Resumo Este estudo objetivou analisar as possíveis associações entre o Escore da Estrutura de Controle de Infecção (EECI), os serviços de saúde e características sociais dos municípios brasileiros. Foram analisados dados secundários do terceiro ciclo 2017-2018 do Programa Nacional de Melhoria do Acesso e Qualidade da Atenção Básica (PMAQ). Seis variáveis independentes - Índice FIRJAN de Desenvolvimento Municipal, número de habitantes, número de Equipes de Saúde da Família que recebiam incentivo financeiro do governo federal, gasto com saúde per capita e número de Equipes de Saúde Bucal modalidades 1 e 2 - foram incluídas para avaliar a influência sobre o EECI, medido para cada município brasileiro. Para a análise dos dados, foi utilizado o modelo de Árvore de Classificação e Regressão no IBM SPSS 25. Foram incluídos 4.900 municípios, e o EECI médio foi de 0,905 (±0,092). Observou-se uma associação positiva entre o gasto com saúde per capita, o desenvolvimento municipal e o desfecho. Por outro lado, municípios com maior número de Equipes de Saúde da Família com incentivo financeiro do governo federal apresentaram menor média do EECI. Os achados sugerem que existem desigualdades nas estruturas de controle de infecções no país, relacionadas aos serviços de saúde e às características sociais dos municípios.

Abstract This study aimed to analyze possible associations between the Infection Control Structure Score (ICSS), health services, and social characteristics of the municipalities in Brazil. Secondary data from the third cycle 2017-2018 of the Brazilian National Program for Improving Primary Care Access and Quality (PMAQ) was analyzed. Six independent variables - FIRJAN Index of Municipal Development, number of inhabitants, number of family health teams receiving a financial incentive from the federal government, healthcare expenditure per capita, and number of Oral Health Teams modalities 1 and 2 - were included to assess their influence on ICSS, measured for each Brazilian town. Data analysis used the Classification and Regression Tree model performed with IBM SPSS 25. A total of 4,900 municipalities were included, and the mean ICSS was 0.905 (±0.092). A positive relationship was observed between healthcare expenditure per capita, municipal development, and the outcome. Conversely, towns with a higher number of family health teams receiving a financial incentive from the federal government showed lower mean ICSS. The findings suggest that inequalities in the infection control structures exist within the country, and they were related to the health services and social characteristics of the municipalities.

ABSTRACT Scorpion envenoming is considered a public health problem in Brazil. A recent study described a variation in the clinical outcome of envenoming by Tityus obscurus in two populations separated by 850 km in the northeastern Amazon region. Our aim was to evaluate whether such clinical and toxinological variations are associated with underlying differences in genetic diversity between these two T. obscurus populations. We obtained DNA from five individuals of each population, in the municipalities of Belém and Santarém, located east and west of the state of Pará, Brazil, respectively. Gene regions encoding mitochondrial DNA (mtDNA) markers cytochrome oxidase subunit I (COI) and ribosomal 16S RNA (16S) were amplified and sequenced. Phylogenetic analyses were performed using maximum likelihood (ML) and Bayesian inferences (BA) for both molecular data (COI and 16S). The sampled T. obscurus populations corresponded to two distinct mtDNA lineages (genetic distance COI K2 P = 0.08 to 0.13; 16S K2 P = 0.10 to 0.11) with no shared mutations between groups and well supported by ML and BA inferences. Based on the divergence values found between eastern and western populations (COI, 0.07 to 0.12; 16S, 0.10), our study confirms the genetic heterogeneity of T. obscurus populations within the state of Pará, which correlates with observed venom and clinical differences, and reinforces the need for mapping the distribution of haplotypes throughout the geographic range of T. obscurus, to aid in future epidemiological, toxinological, and evolutionary studies.

RESUMO O envenenamento por escorpiões é considerado um problema de saúde pública no Brasil. Um estudo recente descreve a variação do quadro clínico de envenenamento por Tityus obscurus em duas populações separadas por uma distância de 850 km no nordeste da Amazônia. O objetivo deste estudo foi avaliar se tais variações clínicas e toxicológicas estão associadas a diferenças subjacentes na diversidade genética entre essas duas populações de T. obscurus. Obtivemos DNA de cinco indivíduos de cada população nos municípios de Belém e Santarém, localizados a leste e oeste do estado do Pará, Brasil, respectivamente. Regiões gênicas que codificam marcadores de DNA mitocondrial (mtDNA) citocromo oxidase subunidade I (COI) e RNA ribossômico 16S (16S) foram amplificadas e sequenciadas. As análises filogenéticas foram realizadas por máxima verossimilhança (ML) e inferência Bayesiana (BA) para ambos os dados moleculares (COI e 16S). As populações de T. obscurus amostradas corresponderam a duas linhagens distintas de mtDNA (distância genética COI K2 P = 0,08 a 0,13; 16S K2 P = 0,10 a 0,11) sem mutações compartilhadas entre os grupos, e bem corroboradas por inferências ML e BA. Com base nos valores de divergência encontrados entre as populações oriental e ocidental (COI, 0,07 a 0,12; 16S, 0,10), nosso estudo confirma a heterogeneidade genética das populações de T. obscurus no estado do Pará. Os resultados são congruentes com as diferenças observadas no quadro clínico dos acidentes e toxicidade do veneno, e reforçam a necessidade de mapear a distribuição de haplótipos em toda a distribuição geográfica de T. obscurus, para auxiliar em futuros estudos epidemiológicos, toxinológicos e evolutivos.

Resumen Introducción: El trasplante renal es el tratamiento de elección de la enfermedad renal en etapa terminal (ERT). Desde marzo de 2020, la actividad de trasplantes en México se ha visto afectada debido a la pandemia de COVID-19. Objetivo: Determinar el impacto en la mortalidad de pacientes en lista de espera (LE) para trasplante renal de donante cadavérico en un hospital de referencia en Yucatán, por suspensión de actividades debido a la pandemia. Material y métodos: Pacientes > 18 años en LE para trasplante renal en este hospital. En caso de muerte de un paciente, se investigó la causa, especialmente si estaba asociada a COVID-19. Un valor de p de dos colas ≤ 0.05 se consideró significativo en todos los análisis. Resultados: La razón de probabilidad de muerte por COVID-19 en un paciente con ERT en la LE en 2020 fue OR = 5.04 (IC 95%: 1.65-7.14, p = 0.023). La razón de probabilidad de morir con ERT en la LE con retraso en las consultas de seguimiento fue de OR = 6.59 (IC 95%: 2.7-16.28, p = 0.008). Conclusión: La probabilidad de muerte de un paciente con ERT en la LE con retraso en las consultas de seguimiento y retención del trasplante es estadísticamente más alta que la probabilidad de muerte por COVID-19.

Abstract Introduction: Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). Since March 2020, transplant activity in Mexico has been affected due to the COVID-19 pandemic. Objective: The aim of the study was to determine the impact on mortality of patients on the waiting list (WL) for cadaveric donor kidney transplantation in a referral hospital in Yucatán, due to suspension of activities due to the pandemic. Material and methods: Patients over 18 years of age on the waiting list for kidney transplantation at this hospital. In the event of a patient's death, the cause was investigated, especially if it was associated with COVID-19. A two-tailed p ≤ 0.05 was considered significant in all analyzes. Results: The odds ratio (OR) of death from COVID-19 in a patient with ESRD in the WL in 2020 was OR = 5.04 (95% CI: 1.65-7.14, p = 0.023). The OR of dying with ESRD in the WL with a delay in the follow-up visits was OR = 6.59 (95% CI: 2.7-16.28, p = 0.008). Conclusion: The probability of death of a patient with ESRD with delayed follow-up visits and transplant retention is statistically higher than the probability of death from COVID-19.

Abstract: The objective of this study was to evaluate the quality of milk and cheese and sensory analysis of cheese from goats that received a diet with different levels of sorghum silage in the diet. Twenty Anglonubian dairy goats were used, with an average age of 2 years, average live weight of 43.7 kg, distributed in a completely randomized design, with five replications. Moisture (P=0.001), total solids (P=0.001), fat (p=0.001), TDE (P=0.006) and protein (P=0.003) of goat cheese showed a significant difference due to the inclusion of silage from goat cheese. sorghum in the diet. The sensory attributes soft appearance (P<.0001), look (P<.0001), salty taste (P<.0001) and smooth texture (P=0.0430) showed a significant difference depending on the level of sorghum silage added to the diet. of goats. In the PC analysis, it is observed that three main components were needed to represent the variation of 64.84% of the data. PC 1 determined 29% of the data variation and was represented by the attributes with the highest averages: attractive aroma (5.87) and global acceptability (7.74). The inclusion of up to 45% of sorghum silage in the diet of goats increased milk and cheese fat, which favored high scores for the attributes of softness and global acceptance.

BACKGROUND A positive Trypanosoma cruzi polymerase chain reaction (PCR) is associated with a worse prognosis in patients with chronic Chagas disease (CD). OBJECTIVES To study the association of clinical, electrocardiographic, and echocardiographic characteristics and biomarker blood levels with positive T. cruzi PCR in chronic CD. METHODS This is a single-centre observational cross-sectional study. Positive T. cruzi PCR association with clinical, electrocardiographic, and echocardiographic characteristics, and biomarker blood levels were studied by logistic regression analysis. p values < 0.05 were considered significant. FINDINGS Among 333 patients with chronic CD (56.4% men; 62 ± 10 years), T. cruzi PCR was positive in 41.1%. Stepwise multivariate logistic regression showed an independent association between positive T. cruzi PCR and diabetes mellitus {odds ratio (OR) 0.53 [95% confidence interval (CI) 0.30-0.93]; p = 0.03}, right bundle branch block [OR 1.78 (95% CI 1.09-2.89); p = 0.02], and history of trypanocidal treatment [OR 0.13 (95% CI 0.04-0.38); p = 0.0002]. Among patients with a history of trypanocidal treatment (n = 39), only four (10%) patients had a positive T. cruzi PCR. MAIN CONCLUSIONS Among several studied parameters, only diabetes mellitus, right bundle branch block, and history of trypanocidal treatment showed an independent association with positive T. cruzi PCR. History of trypanocidal treatment was a strong protective factor against a positive T. cruzi PCR.

Abstract Background: Sarcopenia is a disease that involves skeletal muscle mass loss and is highly prevalent in the older adult population. Moreover, the incidence of sarcopenia is increased in patients with hypertension. Objectives: The study aimed to evaluate the association between the classes of the drugs used for arterial hypertension treatment and the presence or absence of sarcopenia. Methods: 129 older adults with hypertension were evaluated by the researchers who registered the participants medication for arterial hypertension treatment. Sarcopenia level was measured by anthropometric parameters, muscular strength, and functional capacity. The data were analyzed by one-way ANOVA followed by post-hoc test and Fisher’s exact test; statistical significance was set at 0.05. Results: Age was not different between women with different levels of sarcopenia, but significant differences were observed between men with absent sarcopenia (66.8±4.2 years) and men with probable sarcopenia (77.0±10.2 years). Individuals with absent sarcopenia showed higher handgrip strength (men: 33.8±7.4, women: 23.2±4.6 Kgf) in comparison with those with sarcopenia (men with probable sarcopenia: 9.5±3.3 Kgf, women with probable, confirmed, and severe sarcopenia: 11.7±2.5, 12.2±3.0, 11.8±1.8 Kgf, respectively). The analysis showed an association between the type of medication and degree of sarcopenia; diuretics were significantly associated with probable sarcopenia, and angiotensin II receptor blockers (alone or in combination with diuretics) was associated with absence of sarcopenia. Conclusion: In conclusion, handgrip strength was a good method to diagnose sarcopenia, and diuretics were associated with increased risk of sarcopenia in older adults with hypertension.

ABSTRACT Introduction. CIGB-300 is an antitumor peptide that inhibits the CK2-mediated phosphorylation by direct targeting of substrates. This paper aims to describe breakthroughs about the CIGB-300 antineoplastic mechanism related to the inhibition of CK2-mediated phosphorylation and the synergism with anticancer drugs. Methods. CK2 phosphorylation assays were performed with catalytic CK2α subunit or the CK2 holoenzyme in presence or not of CIGB-300. CIGB-300/CK2 interaction was verified by pull-down experiments, in situ colocalization and phosphoproteomic analysis of CIGB-300-treated lung cancer cells were also performed. Synergism of the peptide with anticancer drugs was evaluated in vitro and for Cisplatin; it was also tested in vivo. Besides, comparative proteomics of CIGB-300 combined with Cisplatin was conducted. Results. CIGB-300 targeted the CK2α subunit and inhibited the enzymatic activity of the holoenzyme in different experimental settings. Likewise, phosphoproteomic and Western Blot analysis allowed for knowing the early CK2 inhibition profile elicited by CIGB-300 at 10 and 30 minutes of treatment. Moreover, CIGB-300 did synergize with chemotherapeutics and EGFR inhibitors, and molecular events that reportedly support such synergistic interactions were also known. Conclusions. CIGB-300 inhibits the CK2-mediated phosphorylation by using an alternative mechanism of direct interaction with the enzyme itself. Besides, CIGB-300 synergizes with chemotherapeutics and EGFR inhibitors by modulating different proteins related to drug resistance.

RESUMEN Introducción. El CIGB-300 es un péptido antitumoral inhibidor de la fosforilación de los sustratos de la proteína quinasa CK2. El presente trabajo persigue como objetivo fundamental exponer nuevos elementos vinculados al mecanismo antineoplásico del CIGB-300 relacionados con el modo de inhibición de dicha fosforilación y la sinergia del péptido con drogas anticáncer. Métodos. Se realizaron ensayos de fosforilación mediada por la subunidad catalítica CK2( o la holoenzima en presencia o no del CIGB-300. La interacción CIGB-300/CK2 se verificó mediante ensayos de pull-down, colocalización in situ y además se realizó un análisis fosfoproteómico en células de cáncer de pulmón tratadas con el péptido. El sinergismo del CIGB-300 y las drogas anticáncer se evaluó in vitro y en el caso del cisplatino también in vivo. Además, se realizó un estudio de proteómica comparativa de la combinación del CIGB-300 con el cisplatino. Resultados. El CIGB-300 interaccionó directamente con la subunidad CK2( e inhibió la actividad de la holoenzima en diferentes condiciones experimentales. Asimismo, el análisis de fosfoproteómica y Western blot permitió conocer el perfil de inhibición temprana de CK2 por el CIGB-300 a los 10 min y 30 min Adicionalmente, el CIGB-300 sinergizó con quimioterapéuticos e inhibidores del receptor del factor de crecimiento epidérmico (EGFR) y se conocieron los eventos moleculares que pueden sustentar la sinergia del péptido con las drogas anticáncer estudiadas. Como conclusiones, el CIGB-300 inhibe la fosforilación mediada por CK2 a través de un mecanismo alternativo de interacción directa con la enzima. Además, sinergiza con quimioterapéuticos e inhibidores del EGFR, modulando diferentes proteínas relacionadas con la resistencia a dichas drogas.

ABSTRACT Cyberchondria is a psychopathological behavior that affects people who compulsively consult the internet, by searching the symptoms of different pathologies from which they believe they are suffering, and when influenced by what they read, are sure they have some of these diseases. The aim of this study was to assess the cyberchondria level and associated factors among Brazilian and Portuguese dentists. A total 597 Brazilian and Portuguese dentists participated in this cross-sectional study. They were contacted via WhatsApp and asked to complete an online questionnaire on the Google Forms platform, from January 17 to 31, 2021, during the COVID-19 pandemic. Sociodemographic information was collected and cyberchondria was measured using the Portuguese language version of the Cyberchondria Severity Scale. Binary logistic regression models were used to estimate the unadjusted and adjusted Odds Ratio (OR) and corresponding 95% confidence interval (CI) for the association of cyberchondria and covariates. Each covariate was individually included in the regression model, and the unadjusted OR (95% CI) was estimated. Most participants were Brazilian (62.8%), women (75.5%), married (60.5%) and with children (55.6%). Average age was 42.1 years (+ 12.5). In the final model, it was found that with each increase of one year in age, the chance of a high level of cyberchondria decreased (OR=0.97; 95% CI 0.95-0.98). Brazilian dentists were 1.85 times more likely (95% CI 1.25-2.75) to have a high level of cyberchondria than Portuguese dentists. Women were 1.62 times more likely (95% CI 1.07-2.44) to have a high level of cyberchondria than men. It was concluded that young age, Brazilian nationality, and female gender favored the high level of cyberchondria among the participants in this sample during COVID-19 pandemic.

RESUMO A cibercondria é um comportamento psicopatológico que atinge as pessoas que consultam compulsivamente a internet, pesquisando os sintomas das diferentes patologias de que acreditam estar sofrendo e, quando influenciadas pelo que leem, têm a certeza de possuir alguma dessas doenças. O objetivo deste estudo foi avaliar o nível de cibercondria e fatores associados entre dentistas brasileiros e portugueses. Participaram deste estudo transversal 597 dentistas brasileiros e portugueses. Eles foram contatados via WhatsApp e solicitados a preencher um questionário online na plataforma do Google Forms, no período de 17 a 31 de janeiro de 2021, durante a pandemia de COVID-19. Informações sociodemográficas foram coletadas e a cibercondria foi mensurada através da versão em língua portuguesa da Cyberchondria Severity Scale. Modelos de regressão logística binária foram usados para estimar a Odds Ratio (OR) não ajustada e ajustada e o intervalo de confiança (IC) de 95% correspondente para a associação de cibercondria e covariáveis. Cada covariável foi incluída individualmente no modelo de regressão, e o OR não ajustado (IC 95%) foi estimado. A maioria dos participantes eram brasileiros (62,8%), mulheres (75,5%), casados (60,5%) e com filhos (55,6%). A média de idade foi de 42,1 anos (+ 12,5). No modelo final, verificou-se que a cada aumento de um ano de vida, a chance de um nível elevado de cibercondria diminuía (OR = 0,97; IC95% 0,95-0,98). Os dentistas brasileiros tiveram 1,85 vezes mais probabilidade (IC95% 1,25-2,75) de apresentar alto índice de cibercondria quando comparados aos portugueses. As mulheres tinham 1,62 vezes mais probabilidade (IC 95% 1,07-2,44) de ter um alto nível de cibercondria em comparação com os homens. Concluiu-se que a idade mais jovem, a nacionalidade brasileira e o sexo feminino favoreceram o alto índice de cibercondria entre os participantes desta amostra durante a pandemia COVID-19.

Abstract Isolated left ventricular apical hypoplasia is a rare cardiomyopathy, with a broad range of clinical presentations. Since this entity was already described in association with osteomuscular diseases, mutation in the Lamin A/C gene has been regarded as a possible cause of this disease. This study describes the case of an asymptomatic teenager with isolated left ventricular apical hypoplasia and arthrogriposis but with no mutations in the entire Lamin A/C gene.
