Effectiveness of Probiotic Therapy in the Management of Periodontal Disease in Diabetic Patients: A Scoping Review.

BACKGROUND: Probiotics can compete with periodontal pathogens in the formation of dental biofilm, and they are able to modulate local and systemic immune responses. Thus, its use in diabetic patients with periodontal disease (PD) can overcome the limitations of conventional periodontal treatment. OBJECTIVE: This scoping review aimed to understand the extent and type of evidence in relation to the effects of probiotic therapy on periodontal and glycaemic parameters of diabetic patients with PD. METHODS: An electronic search was performed in the following databases: Cochrane Library, EMBASE, Virtual Health Library (including LILACS and BBO), PubMed (including Medline), Scopus, Web of Science, and Google Scholar. The review included clinical trials on patients with type 2 diabetes, diagnosed with gingivitis or periodontitis, who received probiotic therapy as a single therapy or adjuvant to scaling and root planning, and on whom the analyses of clinical periodontal, immunological, microbiological, or glycaemic parameters were performed. RESULTS: The electronic search yielded a total of 1165 articles. After removing duplicate titles and performing systematic screening, 6 studies were included in the qualitative summary. Probiotic administration improved clinical periodontal parameters (bleeding on probing and probing depth), oxidative stress markers, and inflammatory cytokines (IL-8, IL-10, and TNF-α) in relation to control groups. Experimental groups were also more advantageous in reducing the frequency of periodontopathogenic bacteria. However, the evidence of probiotics in decreasing glycated hemoglobin is still uncertain. CONCLUSION: Probiotics may provide safe additional benefits to periodontal parameters of patients with type 2 diabetes and periodontal disease.

Impact of subnasal lip lift on lip aesthetic: a systematic review.

This study is to perform a systematic review of the literature on surgical correction of the upper lip in order to assess whether the subnasal lip lift technique improves lip aesthetics and maintains its stability. A systematic search was carried out using the PubMed, Science Direct, Scopus, Cochrane Library and EMBASE databases, based on records published until July 2020. The quality of the included studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions. In the absence of randomized clinical trials, prospective or retrospective cohort studies, case control and case series were considered eligible. Of the 464 articles initially found by the two reviewers, 4 were selected, with 2 retrospective cohorts and 2 case series. The results of the studies showed that 92.4% of subnasal lip lift cases were performed in women with an age range between 21 and 65 years (mean of 36.6 years). Only one of the 4 studies did not contain information regarding the sex and age of the patients. The bull's horn excision pattern for subnasal lip lift was used to perform the subnasal lip lift in 75% of the included studies. All studies pointed to an improvement in lip aesthetics after the subnasal lip lift, based on anthropometric measures and the degree of patient satisfaction while maintaining results for varying periods of time (from 12 to 59.1 months). The studies included in this review suggest that the subnasal lip lift improves lip aesthetics in adult patients and maintains its stability for a certain period of time.

Diagnosis, Prognosis and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors.

Mast cell tumors (MCTs) are hematopoietic neoplasms composed of mast cells. It is highly common in dogs and is extremely important in the veterinary oncology field.

Systems analysis of subjects acutely infected with the Chikungunya virus.

The largest ever recorded epidemic of the Chikungunya virus (CHIKV) broke out in 2004 and affected four continents. Acute symptomatic infections are typically associated with the onset of fever and often debilitating polyarthralgia/polyarthritis. In this study, a systems biology approach was adopted to analyze the blood transcriptomes of adults acutely infected with the CHIKV. Gene signatures that were associated with viral RNA levels and the onset of symptoms were identified. Among these genes, the putative role of the Eukaryotic Initiation Factor (eIF) family genes and apolipoprotein B mRNA editing catalytic polypeptide-like (APOBEC3A) in the CHIKV replication process were displayed. We further compared these signatures with signatures induced by the Dengue virus infection and rheumatoid arthritis. Finally, we demonstrated that the CHIKV in vitro infection of murine bone marrow-derived macrophages induced IL-1 beta production in a mechanism that is significantly dependent on the inflammasome NLRP3 activation. The observations provided valuable insights into virus-host interactions during the acute phase and can be instrumental in the investigation of new and effective therapeutic interventions.

Prospective cohort analyzing risk factors for chronic kidney disease progression in children / Coorte prospectiva que analisa os fatores de risco para progressão de doença renal crônica (DRC) em crianças

Abstract Objective: To identify risk factors for chronic kidney disease progression in Brazilian children and to evaluate the interactions between factors. Methods: This was a multicenter prospective cohort in São Paulo, involving 209 children with CKD stages 3-4. The study outcome included: (a) death, (b) start of kidney replacement therapy, (c) eGFR decrease >50% during the followup. Thirteen risk factors were tested using univariate regression models, followed by multivariable Cox regression models. The terms of interaction between the variables showing significant association with the outcome were then introduced to the model. Results: After a median follow-up of 2.5 years (IQR = 1.4-3.0), the outcome occurred in 44 cases (21%): 22 started dialysis, 12 had >50% eGFR decrease, seven underwent transplantation, and three died. Advanced CKD stage at onset (HR = 2.16, CI = 1.14-4.09), nephrotic proteinuria (HR = 2.89, CI = 1.49-5.62), age (HR = 1.10, CI = 1.01-1.17), systolic blood pressure Z score (HR = 1.36, CI = 1.08-1.70), and anemia (HR = 2.60, CI = 1.41-4.77) were associated with the outcome. An interaction between anemia and nephrotic proteinuria at V1 (HR = 0.25, CI = 0.06-1.00) was detected. Conclusions: As the first CKD cohort in the southern hemisphere, this study supports the main factors reported in developed countries with regards to CKD progression, affirming the potential role of treatments to slow CKD evolution. The detected interaction suggests that anemia may be more deleterious for CKD progression in patients without proteinuria and should be further studied.

Resumo Objetivo: Identificar os fatores de risco para progressão da DRC em crianças do Brasil e avaliar as interações entre os fatores. Métodos: Coorte prospectiva multicêntrica em São Paulo, envolvendo 209 crianças com DRC em estágios 3-4. O desfecho do estudo incluiu: a) óbito, b) início da terapia de substituição renal, c) redução de > 50% na taxa estimada de filtração glomerular (eGFR) durante o acompanhamento. Foram testados 13 fatores de risco com o modelo de regressão univariada seguido do modelo de regressão multivariado de Cox. Os termos de interação entre as variáveis mostraram associação significativa e foram introduzidos ao modelo. Resultados: Após média de acompanhamento de 2,5 anos (IIQ = 1,4 a 3,0), 44 casos (21%) apresentaram desfecho: 22 iniciaram diálise, 12 apresentaram redução de > 50% na eGFR, sete foram submetidos a transplante e três morreram. Estágio avançado de DRC no acometimento (RR = 2,16, IC = 1,14-4,09), proteinúria nefrótica (RR = 2,89, IC = 1,49-5,62), idade (RR - 1,10, IC = 1,01-1,17), escore Z da pressão arterial sistólica (RR = 1,36, IC = 1,08-1,70) e anemia (RR = 2,60, IC - 1,41-4,77) foram associados ao resultado. Foi detectada interação entre anemia e proteinúria nefrótica na primeira visita (V1) (RR = 0,25, IC = 0,06-1,00). Conclusões: Como a primeira coorte de DRC no hemisfério sul, este estudo é concordante com os principais fatores relatados em países desenvolvidos com relação à progressão da DRC, afirmando o possível papel dos tratamentos para mostrar a evolução da DRC. A interação detectada sugere que a anemia pode ser mais nociva na progressão da DRC em pacientes sem proteinúria e deve ser ainda mais estudada.

Comparative study between biopsy and brushing sampling methods for detection of human papillomavirus in oral and oropharyngeal cavity lesions, / Estudo comparativo entre biópsia e escovado na pesquisa do papilomavírus humano em lesões de cavidade oral e de orofaringe

ABSTRACT INTRODUCTION: Many epidemiological studies have suggested that human papillomavirus (HPV), especially type 16, is involved in the genesis of squamous cell carcinoma of the oral cavity and oropharynx, especially in young, non-smoking patients; thus, its detection in lesions in this region is important. OBJECTIVE: To clarify the capacity of the brushing sampling method to detect the presence of HPV in oral or oropharyngeal lesions through polymerase chain reaction (PCR) testing, and to compare the results with those obtained by biopsy. METHODS: Prospective study of adult patients with oral or oropharyngeal lesions assessed by PCR, comparing biopsy specimens with samples obtained by the brushing method. The study was approved by the Research Ethics Committee of the institution. RESULTS: A total of 35 sample pairs were analyzed, but 45.7% of the brushing samples were inadequate (16/35) and, thus, only 19 pairs could be compared. There was agreement of results in 94.7% (18/19) of the pairs, with HPV identified in 16 of them. HPV DNA was detected in 8.6% (3/35) of biopsy and 5.7% (2/35) of brushing samples. CONCLUSION: There was no statistically significant difference between the two methods, but the brushing sampling method showed a higher number of inadequate samples, suggesting that it is an unreliable method for surveillance.

Resumo INTRODUÇÃO: Muitos estudos epidemiológicos indicam a participação do papilomavírus humano, especialmente o tipo 16, na carcinogênese dos tumores espinocelulares das cavidade oral e oro-faríngea, principalmente em jovens e não fumantes, sendo portanto importante sua detecção nas lesões desta região. OBJETIVO: Elucidar a habilidade do escovado em detectar o papilomavírus humano, pela reação em cadeia da polimerase, nas lesões orais e orofaríngeas, comparando os resultados com os obtidos por biópsia. MÉTODO: Estudo prospectivo de pacientes com lesões orais e orofaríngeas, pela reação em cadeia da polimerase, no qual foram pareados os resultados de amostras obtidas por escovado e por biópsia. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da instituição. RESULTADO: Foram analisados 35 pares de amostras, porém estavam inapropriadas para análise 45,7% (16/35) das amostras obtidas por escovado, e portanto, somente 19 pares puderam ser comparados. Em 94,7% dos pares houve concordância dos resultados, sendo encontrado o papilomavírus humano − 16 em um destes pares. O ácido desoxirribonucleico do papilomavírus humano foi detectado em 8,6% (3/35) das biópsias e em 5,7% (2/35) dos escovados. CONCLUSÃO: Não houve diferença estatística entre os métodos, mas como houve um grande número de amostras obtidas por escovado inapropriadas, este parece não ser confiável para o rastreamento.

Sleep deprivation alters thyroid hormone economy in rats.

NEW FINDINGS: What is the central question of this study? The relationship between the thyroid system and sleep deprivation has seldom been assessed in the literature, and mounting evidence exists that sleep disturbances influence human lifestyles. The aim of this study was to investigate the hypothalamic-pituitary-thyroid axis and thyroid hormone metabolism in sleep-deprived and sleep-restricted rats. What is the main finding and its importance? Central hypothyroidism and high thyroxine (T4 ) to 3,5,3'-triiodothyronine (T3 ) activation in brown adipose tissue were observed following sleep deprivation. Sleep-restricted rats exhibited normal thyroid-stimulating hormone and T4 concentrations despite increased circulating T3 . Sleep recovery for 24 h did not normalize the high T3 concentrations, suggesting that high T3 is a powerful counterregulatory mechanism activated following sleep deprivation. Modern life has shortened sleep time, and the consequences of sleep deprivation have been examined in both human subjects and animal models. As the relationship between thyroid function and sleep deprivation has not been fully investigated, the aim of this study was to assess the hypothalamic-pituitary-thyroid axis and thyroid hormone metabolism following paradoxical sleep deprivation (PSD) and sleep restriction (SR) in rats. The effects of a 24 h rebound period were also studied. Male Wistar rats (200-250 g, n = 10 per group) were subjected to sleep deprivation via the modified multiple platform method. Rats were assigned to the following seven groups: control, PSD for 24 or 96 h, 24 or 96 h of sleep deprivation with rebound (PSD24R and PSD96R), SR for 21 days (SR21) and SR21 with rebound (SR21R). Blood samples were collected to determine the 3,5,3'-triiodothyronine (T3 ), thyroxine (T4 ) and thyroid-stimulating hormone concentrations. Brown adipose tissue iodothyronine deiodinase type 2 (D2) activity was also evaluated. Body weight gain was dramatically reduced (by ∼50-100%) in all sleep-deprived and sleep-restricted rats; rebound restored this parameter in only the PSD24R group. The serum TSH and T4 concentrations decreased, whereas T3 increased in both the PSD24 and PSD96 groups compared with control animals (P < 0.05). Only PSD24R and PSD96R normalized T4 and thyroid-stimulating hormone concentrations, respectively, independently of the higher circulating T3 concentrations (∼20-30%) noted in all groups compared with control animals (P < 0.05). Brown adipose tissue D2 activity increased in the PSD 24 and 96 h groups (∼10 times), and PSD24R was more effective than PSD96R at restoring basal brown adipose tissue D2 activity. Our data suggest that thyroid hormone metabolism adapts to sleep deprivation-induced hypothalamic-pituitary-thyroid alterations and increases T4 to T3 activation peripherally, thereby increasing circulating T3 in rats.

Determination of HPV prevalence in oral/oropharyngeal mucosa samples in a rural district of São Paulo.

UNLABELLED: Knowledge about HPV infection in the oral cavity/oropharynx may contribute to the elucidation of the role it plays in Head and Neck Squamous Cell Carcinoma (HNSCC). OBJECTIVE: To determine the effectiveness of the methodology used for sampling the oral cavity and oropharynx mucosae and to determine the prevalence of HPV in the oral cavity and oropharynx of adults and children. METHOD: The study population was served by an assistance program in a rural district of São Paulo. The subjects were asked to donate samples regardless of complaints. RESULTS AND CONCLUSION: The study included 47 men, 77 women and 22 children, of which the oral cavity samples were obtained by gargling with commercially-available antiseptic mouthwash. We found 3 positive samples (2.4%) in adults: 2 HPV 55 and one HPV 58. No positive results were found in children. Furthermore we concluded that the sampling method with the mouthwash proved effective and fast for the detection of HPV in the oral cavity and oropharynx in the general population.

Tratamento endoscópico do refluxo vesicoureteral após a cura da instabilidade vesical / Endoscopic treatment of vesico-ureteral reflux following cure of vesical instability

Objetivo: Avaliar a eficácia do uso de "dextranomer hyaluronic acid copopymer (Deflux®)" no tratamento de pacientes com disfunção miccional e refluxo vesicoureteral (RVU) persistente após a cura da disfunção miccional. Pacientes e Métodos: Dos pacientes portadores de disfunção miccional e RVU, 30 foram submetidos ao tratamento do refluxo persistente com Deflux®, após a cura da disfunção miccional. Dos pacientes, 22 eram do sexo feminino e oito do sexo masculino, com idade variando de um ano e dez meses a 16 anos. De um total de 46 unidades ureterovesicais refluxivas, nenhuma apresentava RVU grau I, quatro RVU grau II, 38 apresentavam RVU grau III e quatro apresentavam RVU grau IV. O período de acompanhamento variou de seis meses a cinco anos. Quando o RVU persistiu, apesar do tratamento, uma segunda e, eventualmente, uma terceira injeção foi programada, utilizando a mesma técnica descrita. Resultados: Em todas as quatro unidades ureterais apresentando RVU grau II o refluxo desapareceu após uma simples injeção de Deflux®. Das 38 unidades ureterais apresentando RVU grau III, em 30 o refluxo desapareceu com apenas uma aplicação, em duas unidades após duas aplicações e em uma unidade desapareceu somente após a terceira aplicação. Das quatro unidades que apresentavam refluxo grau IV, somente em uma unidade o RVU desapareceu. Conclusão: O tratamento com Deflux® foi efetivo em mais de 80% dos casos em que existia um RVU grau II ou III, mas foi capaz de tratar o RVU em somente em uma das quatro unidades com RVU grau IV. Uma segunda injeção endoscópica pode eventualmente ser eficaz nos casos de falha inicial do tratamento.
