Three-dimensional-printed scaffolds for periodontal regeneration: A systematic review.

Background: As current ethical codes preclude determining whether the clinical improvements obtained with the use of three-dimensional (3D)-printed scaffolds represent true periodontal regeneration, the histological proof of evidence for regeneration must be demonstrated in animal models. Thus, this systematic review investigated the regenerative potential of 3D-printed scaffolds in animal models of periodontal defects. Materials and Methods: A systematic search was performed in four databases (Medline, Embase, Web of Science, and Scopus) to identify preclinical controlled studies that investigated the use of 3D-printed scaffolds for periodontal regeneration. Studies limited to periodontal defects treated with 3D scaffolds were eligible for inclusion. The primary outcome was periodontal regeneration, assessed histologically as new bone, cementum, and periodontal ligament (PDL). This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Quality was assessed according to the SRYCLE score. Results: Six studies met the inclusion criteria. Scaffolds were designed using computer-aided design software. While the absence of a scaffold resulted in defects repaired mainly with fibrous connective tissue, the use of nonguiding 3D scaffolds promoted some bone formation. Notably, the regeneration of cementum and functional PDL fibers perpendicularly inserted into the root surface and the alveolar bone was limited to the defects treated with multi-compartment fiber-guiding or ion-containing 3D scaffolds. Nevertheless, the quality of the evidence was limited due to the unclear risk of bias. Conclusions: Despite the limitations of the available evidence, the current data suggest that the use of printed multi-compartment fiber-guiding or ion-containing 3D scaffolds improves periodontal regeneration in animal models.

Syndecan-1 predicts hemodynamic instability in critically ill patients under intermittent hemodialysis.

Introduction: Up to 70% of intermittent hemodialysis (IHD) sessions in critically ill patients are complicated by hemodynamic instability. Although several clinical characteristics have been associated with hemodynamic instability during IHD, the discriminatory capacity of predicting such events during IHD sessions is less defined. In the present study, we aimed to analyse endothelium-related biomarkers collected before IHD sessions and their capacity to predict hemodynamic instability related to IHD in critically ill patients. Methods: In this prospective observational study, we enrolled adult critically ill patients with acute kidney injury who required fluid removal with IHD. We screened each included patient daily for IHD sessions. Thirty minutes before each IHD session, each patient had a 5-mL blood collection for measurement of endothelial biomarkers-vascular cell adhesion molecule-1 (VCAM-1), angiopoietin-1 and -2 (AGPT1 and AGPT2) and syndecan-1. Hemodynamic instability during IHD was the main outcome. Analyses were adjusted for variables already known to be associated with hemodynamic instability during IHD. Results: Plasma syndecan-1 was the only endothelium-related biomarker independently associated with hemodynamic instability. The accuracy of syndecan-1 for predicting hemodynamic instability during IHD was moderate [area under the receiver operating characteristic curve 0.78 (95% confidence interval 0.68-0.89)]. The addition of syndecan-1 improved the discrimination capacity of a clinical model from 0.67 to 0.82 (P < .001) and improved risk prediction, as measured by net reclassification improvement. Conclusion: Syndecan-1 is associated with hemodynamic instability during IHD in critically ill patients. It may be useful to identify patients who are at increased risk for such events and suggests that endothelial glycocalyx derangement is involved in the pathophysiology of IHD-related hemodynamic instability.

Increased interregional virus exchange and nucleotide diversity outline the expansion of chikungunya virus in Brazil.

The emergence and reemergence of mosquito-borne diseases in Brazil such as yellow fever, zika, chikungunya, and dengue have had serious impacts on public health. Concerns have been raised due to the rapid dissemination of the chikungunya virus across the country since its first detection in 2014 in Northeast Brazil. In this work, we carried out on-site training activities in genomic surveillance in partnership with the National Network of Public Health Laboratories that have led to the generation of 422 chikungunya virus genomes from 12 Brazilian states over the past two years (2021-2022), a period that has seen more than 312 thousand chikungunya fever cases reported in the country. These genomes increased the amount of available data and allowed a more comprehensive characterization of the dispersal dynamics of the chikungunya virus East-Central-South-African lineage in Brazil. Tree branching patterns revealed the emergence and expansion of two distinct subclades. Phylogeographic analysis indicated that the northeast region has been the leading hub of virus spread towards other regions. Increased frequency of C > T transitions among the new genomes suggested that host restriction factors from the immune system such as ADAR and AID/APOBEC deaminases might be driving the genetic diversity of the chikungunya virus in Brazil.

Migraine Attacks Triggered by Ingestion of Watermelon.

INTRODUCTION: Ingesting some foods can trigger headache attacks in migraine patients. Diet-sourced citrulline activates the l-arginine-nitric oxide pathway, acting on the pathophysiology of migraine. METHODS: The study was a clinical trial, interventional, controlled, and with group comparison. The sample was non-random, composed of 38 volunteers with migraine and 38 without headache (control). Both groups ingested a portion of watermelon to determine the onset of headache attacks. Before and after ingesting watermelon, they underwent blood collections to determine serum nitrite levels. RESULTS: There were 38 volunteers diagnosed with migraine without aura and 38 controls, whose mean age was, respectively, 22.4 ± 1.5 and 22.9 ± 3.1 years (p = 0.791). Headache was triggered by watermelon ingestion after 124.3 ± 20.5 min of ingestion in 23.7% (9/38) of the migraine volunteers and in none of the controls (p = 0.002). There was an increase in serum nitrite levels, both in migraine volunteers (23.4%) and in the control group (24.3%), after watermelon ingestion. This difference was significant (p < 0.001). DISCUSSION: Watermelon ingestion triggered headache attacks in migraine patients and increased serum nitrite levels, attesting to a possible activation of the l-arginine-nitric oxide pathway.

Increased interregional virus exchange and nucleotide diversity outline the expansion of the chikungunya virus ECSA lineage in Brazil.

The emergence and reemergence of mosquito-borne diseases in Brazil such as Yellow Fever, Zika, Chikungunya, and Dengue have had serious impacts on public health. Concerns have been raised due to the rapid dissemination of the chikungunya virus (CHIKV) across the country since its first detection in 2014 in Northeast Brazil. Faced with this scenario, on-site training activities in genomic surveillance carried out in partnership with the National Network of Public Health Laboratories have led to the generation of 422 CHIKV genomes from 12 Brazilian states over the past two years (2021-2022), a period that has seen more than 312 thousand chikungunya fever cases reported in the country. These new genomes increased the amount of available data and allowed a more comprehensive characterization of the dispersion dynamics of the CHIKV East-Central-South-African (ECSA) lineage in Brazil. Tree branching patterns revealed the emergence and expansion of two distinct subclades. Phylogeographic analysis indicated that the northeast region has been the leading hub of virus spread towards other regions. Increased frequency of C>T transitions among the new genomes suggested that host restriction factors from the immune system such as ADAR and AID/APOBEC deaminases might be driving CHIKV ECSA lineage genetic diversity in Brazil.

Assistência de enfermagem à criança com necessidades especiais de saúde na atenção primária / Nursing care for children with special health care needs in primary care

Objetivo: Analisar, nas evidências científicas, a assistência de enfermagem às crianças com necessidades especiais de saúde na Atenção Primária à Saúde.Métodos: Revisão integrativa da literatura, com busca e seleção nas bases de dados MEDLINE via PubMed®, LILACS, Embase, SCOPUS e na biblioteca eletrônica Scielo. Foram incluídos dez estudos primários, disponíveis na íntegra, publicados entre 2011 e 2021, em inglês, português e espanhol. Resultados: Apesar da grande necessidade de conhecimento técnico na assistência às CRIANES, é evidente a necessidade de essas crianças e suas famílias serem atendidas naintegralidade, e não apenas com abordagens de caráter biomédico que limitam a assistência de enfermagem quanto à identificação de aspectos relacionados ao quadro clínico dessas crianças. Evidenciou-se ainda que os enfermeiros, em sua maioria, não se sentem preparados para prestar assistência adequada devido à complexidade das condições de saúde, à deficiêncianaformação profissional ou pela ausência de capacitações periódicas e específicas após se formarem. Conclusão: A assistência de enfermagem no cuidado às CRIANES acontece de forma fragmentada e com ações pautadas no modelo biomédico. Os achados mostraram pouco acesso e inclusão, além de escassez na oferta de capacitação de enfermeiros como um problema frequente na atenção primária. Descritores: Atenção Primária à Saúde.

Objective: To analyze, based on scientific evidence, nursing care for children with special health care needs in Primary Health Care.Methods: Integrative literature review, with search and selection in MEDLINE databases via PubMed®, LILACS, Embase, SCOPUS and in the Scielo electronic library. Ten primary studies were included, available in full, published between 2011 and 2021, in English, Portuguese and Spanish. Results: Despite the great need for technical knowledge in assisting CSHCN, it is evidentthe need for these children and their families to be attended in full, and not just with biomedical approaches that limit nursing care in terms of identifying aspects related to the clinical picture of these children. It was also evidenced that nurses,for the most part, do not feel prepared to provide adequate care due to the complexity of the health conditions, the deficiency in professional training or the lack of periodic and specific training after graduation. Conclusion: Nursing care in the care for CSHCN happens in a fragmented way and with actions based on the biomedical model. The findings showed little access and inclusion, in addition to a shortage in the provision of training for nurses as a frequent problem in primary care. Descriptors: Primary Health Care.

Endothelial biomarkers as predictors for haemodialysis need in severe leptospirosis patients (Weil's disease).

OBJECTIVE: To investigate the prediction ability of vascular injury biomarkers for haemodialysis requirement in patients with severe leptospirosis. METHODS: Prospective study with severe leptospirosis patients hospitalised in Fortaleza, Brazil. Blood samples were collected hospital admission to quantify vascular injury biomarkers: syndecan-1, ICAM-1, VCAM-1, angiopoietin-2 and FGF-23. Two groups were evaluated according to haemodialysis requirement during hospital stay. RESULTS: Twenty-seven patients were included, with a mean age of 39 ± 18 years. 88.9% were males. 53.8% needed haemodialysis and presented higher levels on hospital admission of syndecan-1 (572 [300-811] vs. 263 [106-421] ng/ml; p = 0.03), angiopoietin-2 (1.52 [0.72-2.72] vs. 0.63 [0.4-1.38] ng/ml; p = 0.01), and FGF-23 (291 [56-2031] vs. 10 [10-806] pg/ml; p = 0.021). Syndecan-1 showed significant correlation with creatinine (r = 0.546; p = 0.05) and total bilirubin levels (r = 0.534; p = 0.013) on hospital admission. Angiopoietin-2 showed significant correlation with creatinine levels (r = 0.513; p = 0.009) on hospital admission and with number of haemodialysis sessions (r = 0.406; p = 0.049). No significant correlation was found with FGF-23. Regarding prognostic performance, combined syndecan-1 and angiopoietin-2 levels had a better ability to predict haemodialysis need in patients with severe leptospirosis (AUC-ROC = 0.744 [95% CI: 0.545-0.943] p = 0.035). CONCLUSION: Syndecan-1 and angiopoietin-2 were associated with haemodialysis need in patients with severe leptospirosis and may be useful to improve therapeutic approach and reduce mortality.

Use of nasal mucosa graft in tympanoplasty / Uso do enxerto de mucosa nasal na timpanoplastia

Abstract Introduction Tympanoplasty techniques with different types of graft have been used to close tympanic perforations since the 19th century. Tragal cartilage and temporalis fascia are the most frequently used types of graft. They lead to similar functional and morphological results in most cases. Although little published evidence is present, nasal mucosa has also been shown to be a good alternative graft. Objective Surgical and audiological outcomes at the six-month follow-up in type I tympanoplasty using nasal mucosa and temporalis fascia grafts were analyzed. Methods A total of 40 candidates for type I tympanoplasty were randomly selected and divided into the nasal mucosa and temporalis fascia graft groups with 20 in each group. The assessed parameters included surgical success; the rate of complete closure of tympanic perforation and hearing results; the difference between post- and pre-operative mean quadritonal airway-bone gap, six months after surgery. Results Complete closure of the tympanic perforation was achieved in 17 of 20 patients in both groups. The mean quadritonal airway-bone gap closures were11.9 and 11.1 dB for the nasal mucosa and temporalis fascia groups, respectively. There was no statistically significant difference between the groups. Conclusion The nasal mucosa graft can be considered similar to the temporal fascia when considering the surgical success rate of graft acceptance and ultimate audiological gain.

Resumo Introdução Técnicas de timpanoplastia com diferentes tipos de enxerto têm sido usadas para fechar perfurações timpânicas desde o século XIX. A cartilagem tragal e a fáscia temporal são os tipos de enxerto mais usados, com resultados funcionais e morfológicos semelhantes na maioria dos casos. Embora ainda com poucas evidências publicadas, a mucosa nasal tem se mostrado uma boa opção de enxerto. Objetivo Comparar os resultados cirúrgicos e audiológicos da timpanoplastia tipo I com enxerto de mucosa nasal e de fáscia temporal em seis meses de seguimento. Método Foram selecionados aleatoriamente 40 pacientes candidatos a timpanoplastia tipo I divididos nos grupos enxerto de mucosa nasal e de fáscia temporal com 20 em cada grupo. Os parâmetros avaliados incluíram sucesso cirúrgico, ou seja, a taxa de fechamento completo da perfuração timpânica, e resultados audiológicos; diferença entre o gap quadritonal médio do gap aéreo-ósseo pré e pós-operatório após seis meses da cirurgia. Resultados O fechamento completo da perfuração timpânica foi alcançado em 17 de 20 pacientes no grupo mucosa nasal, como também no grupo fáscia temporal. O ganho quadritonal médio do gap aéreo-ósseo foi de 11,9 dB no grupo mucosa nasal e 11,1 dB no grupo fáscia temporal, respectivamente. Não houve diferença estatisticamente significante entre os grupos. Conclusão O enxerto de mucosa nasal pode ser considerado semelhante ao da fáscia temporal quando se considera o sucesso cirúrgico de pega do enxerto e o ganho audiológico.

Urinary tubular biomarkers as predictors of death in critically ill patients with COVID-19.

Aim: To evaluate the prediction capacity of urinary biomarkers for death in critically ill patients with COVID-19. Methods: This is a prospective study with critically ill patients due to COVID-19 infection. The urinary biomarkers NGAL, KIM-1, MCP-1 and nephrin were quantified on ICU admission. Results: There was 40% of death. Urinary nephrin and MCP-1 had no association with death. Tubular biomarkers (proteinuria, NGAL and KIM-1) were predictors of death and cut-off values of them for death were useful in stratify patients with worse prognosis. In a multivariate cox regression analysis, only NGAL remains associated with a two-mount survival chance. Conclusion: Kidney tubular biomarkers, mostly urinary NGAL, had useful capacity to predict death in critically ill COVID-19 patients.

Association between angiopoietin-2 and functional cardiac remodeling in hemodialysis patients with normal left ventricular ejection.

Cardiac remodeling is the initial process in heart failure development. The aim of this study is to evaluate the association between endothelium-related biomarkers and cardiac remodeling in hemodialysis (HD) patients and how the presence of high blood pressure and diabetes mellitus modulates these associations. This was a cross-sectional study with adult HD and normal left ventricular (LV) ejection fraction-LVEF-patients. The authors correlated several endothelium-related biomarkers with echocardiographic indices-LV mass index (LVMi), LVEF, global longitudinal strain, mitral E/e', and aortic root diameter. Seventy-one patients were included, with 37 women (52.1%) and mean age of 54.3 ± 16.8 years. Angiopoietin-2 (AGPT2) was inversely correlated with global longitudinal strain (r = -.374, p = .001) and directly with E/e' (r = .265, p = .025). After adjustment, only AGPT2 was significantly associated with global longitudinal strain. blood pressure and diabetes mellitus were independent moderators for the AGPT2 and global longitudinal strain association. The conditional association was significant only when the mean pre-HD blood pressure was above 97.5 mmHg or in diabetes mellitus patients. Finally, there was an interaction between diabetes mellitus and blood pressure when moderating the conditional effect of AGPT2 on global longitudinal strain. While in non-diabetic patients, the association between AGPT2 with global longitudinal strain was significant only with pre-HD blood pressure levels as high as 110 mmHg, in diabetic patients, this association was significant with pre-HD blood pressure as low as 90 mmHg. Higher levels of AGPT2 were associated with worse cardiac function as determined by lower global longitudinal strain values. This association was moderated by blood pressure and diabetes mellitus, suggesting that the effects of AGPT2 on cardiac remodeling is dependent of such circumstances.
