RESUMO

Objetivo: O estudo teve por objetivo avaliar o Programa Nacional de Controle do Tabagismo (PNCT) em Mato Grosso do Sul, taxas de cobertura, abandono, cessação, uso de medicamentos, rede de serviços de saúde e as razões pelas quais algumas Equipes de Saúde da Família de Campo Grande ainda não aderiram ao programa. Métodos: Trata-se de uma pesquisa descritiva, com abordagem quantitativa, baseada em dados primários e secundários sobre o PNCT em Mato Grosso do Sul. Os dados primários foram obtidos por meio de questionário aplicado aos profissionais das Equipes de Saúde da Família (ESF) de Campo Grande, sem oferta do programa e avaliados quanto à frequência e presença de correlação entre as variáveis analisadas utilizando V de Cramer e teste de χ2. Os dados secundários foram obtidos do consolidado do Instituto Nacional de Câncer José Alencar Gomes da Silva com os registros produzidos pelos serviços. Resultados: As taxas de adesão, efetividade e apoio farmacológico na capital e interior foram: 66,80 e 59,79%; 20,58 e 34,91%; 32,14 e 99,86%, respectivamente. A oferta do programa ocorreu em 49,37% municípios e 43,85% das Unidades Básicas de Saúde (UBS) estimadas. Houve correlações entre ser capacitado e implantar o programa; treinamento de ingresso e oferta na UBS. As dificuldades relatadas pelos profissionais foram a pandemia de COVID-19, a sobrecarga e/ou equipe pequena e/ou falta de tempo e a ausência de capacitação/treinamento. Conclusões: O PNCT em Mato Grosso do Sul apresenta baixa cobertura e oferta restrita na rede de saúde, além do desempenho mediano de assistência aos tabagistas. Evidencia-se a necessidade de investimento em capacitação/treinamento, prioritariamente para as ESF de Campo Grande, dando-lhes condições de responder às necessidades de promoção da saúde, reconhecendo o programa como de maior custo-efetividade.


Objective: The objective of this study was to evaluate the National Tobacco Control Program (PNCT) in Mato Grosso do Sul, coverage rates, dropout, cessation, use of medication, the health services network and the reasons why Family Health Teams in Campo Grande have not yet joined the program. Methods: This was a descriptive study with a quantitative approach, based on primary and secondary data on the PNCT in Mato Grosso do Sul. The primary data were obtained by means of a questionnaire administered to Family Health Teams (ESF) in Campo Grande, which did not offer the program and evaluated the frequency and presence of correlation between the variables analyzed using Cramer's V test and the χ2 test. The secondary data were obtained from the consolidated records of the José Alencar Gomes da Silva National Cancer Institute with the records produced by the services. Results: The rates of adherence, effectiveness and pharmacological support in the capital and interior were: 66.80 and 59.79%; 20.58 and 34.91%; and 32.14 and 99.86%, respectively. The program was offered in 49.37% of the municipalities and 43.85% of the Basic Health Units (UBS) estimated. There were correlations between being trained and implementing the program and entry training and provision in the UBS. The difficulties reported by professionals were the COVID-19 pandemic, overload and/or a small team and/or lack of time and the absence of training. Conclusions: The PNCT in Mato Grosso do Sul has low coverage and restricted supply in the health network, in addition to average performance in assisting smokers. There is a clear need to invest in capacitation/training, primarily for the ESF in Campo Grande, enabling them to respond to the needs of health promotion, recognizing the program as more cost-effective.

RESUMO

Trans-chalcone (TC) is a flavonoid precursor characterized by a wide spectrum of action, with anti-inflammatory and antioxidant effects. However, no validated methods are available in official compendia for the analysis of this substance. Thus, the aim of this work was to develop and validate a simple, fast, and reproducible spectrophotometric method for the analysis of TC in raw material, and in topical pharmaceutical formulation containing TC. The established conditions were: methanol as extracting solvent, and detection wavelength of 309 nm by UV spectrophotometer. All tests followed the rules of Resolution RDC 166, 2017. The proposed method was selective. Linearity was demonstrated in the concentration range of 1 to 8 µg/mL (r = 0.999). Repeatability and intermediate precision were confirmed by low relative standard deviation values of 1.53% and 2.70% for TC, and of 1.73% and 2.91% for formulation containing TC. Accuracy, evaluated through recovery test, was adequate, with minimum of 98.24% and maximum of 100.23% of recovery. It was observed that the small deliberate modifications done did not interfere with the results, demonstrating the method is robust. The results showed that the method was considered suitable for the intended purpose, inexpensive, easy to apply, selective, linear, precise, accurate, and robust for the determination TC, and pharmaceutical formulation containing TC. Thus, the method developed satisfies the need for an analytical method for the determination of TC, and topical formulation containing TC, being effective, innovative and able to aid in the development of the pharmaceutical field.

RESUMO

Las actividades que realiza el profesional de la enfermería les producen quebranto en la salud, siendo el estrés el primer factor que va a afectar el ritmo propio, ocasionando irritabilidad y ansiedad. La práctica físico-deportiva tiene un efecto positivo sobre su salud física y mental debido a que produce liberación de endorfinas, lo que conlleva una reducción de la ansiedad, la depresión y el estrés, ya que cualquier tipo de actividad física, ya sea de bajo o alto impacto, libera estas sustancias que actúan directamente sobre el cerebro, produciendo sensación de bienestar y relajación inmediata. Se presenta una investigación con un diseño no experimental, desde el enfoque cuantitativo de tipo descriptivo comparativo de corte transversal. Tiene como objetivo: determinar las relaciones entre actividad física y regulación emocional de un grupo de enfermeras (o) s del Hospital Sur en Chilpancingo, Guerrero, México. Se aplicó la Escala para Evaluación de la Inteligencia Emocional TMMS-24 y el Cuestionario Internacional de Actividad Física (IPAQ). Para determinar la relación entre las variables se empleó la Correlación del Rho de Spearman. Las dimensiones estudiadas son la atención, claridad y reparación emocional por parte de la variable dependiente (Control emocional) y las dimensiones Alta, Media y Baja por la variable independiente (Actividad física). En la comunidad donde se observaron los signos y síntomas de nerviosismo, agitación o tensión asociados a situaciones de ansiedad y estrés, se establecen correlaciones directas entre la intensidad de la actividad física y el control emocional de los sujetos investigados, o sea, a menor intensidad de la actividad física menor control y regulación emocional.


As atividades realizadas pelo profissional de enfermagem causam-lhe problemas de saúde, sendo o estresse o primeiro fator que afetará seu próprio ritmo, causando irritabilidade e ansiedade. A prática físico-esportiva tem um efeito positivo sobre sua saúde física e mental, pois produz uma liberação de endorfinas, o que leva a uma redução da ansiedade, da depressão e do estresse, pois qualquer tipo de atividade física, seja ela de baixo ou alto impacto, libera essas substâncias que atuam diretamente no cérebro, produzindo uma sensação de bem-estar e relaxamento imediato. A pesquisa é apresentada em um desenho não-experimental, a partir de uma abordagem quantitativa, descritiva, comparativa, transversal e de corte transversal. Seu objetivo é determinar a relação entre a atividade física e a regulação emocional em um grupo de enfermeiras do Hospital Sur em Chilpancingo, Guerrero, México. Foram aplicados o Emotional Intelligence Rating Scale TMMS-24 e o International Physical Activity Questionnaire (IPAQ). A Correlação Rho de Spearman foi usada para determinar a relação entre as variáveis. As dimensões estudadas são Atenção, Clareza e Reparação Emocional para a variável dependente (Controle Emocional) e as dimensões Alta, Média e Baixa para a variável independente (Atividade Física). Na comunidade onde foram observados os sinais e sintomas de nervosismo, agitação ou tensão associados a situações de ansiedade e estresse, foram estabelecidas correlações diretas entre a intensidade da atividade física e o controle emocional dos sujeitos investigados, ou seja, quanto menor a intensidade da atividade física, menor o controle e a regulação emocional.


The activities carried out by the nursing professional produce them health problems, with stress being the first factor that will affect one's own rhythm, causing irritability and anxiety. Physical-sports practice has a positive effect on their physical and mental health because it produces the release of endorphins, which leads to a reduction in anxiety, depression and stress because any type of physical activity, whether low or high impact, releases these substances that act directly on the brain, producing a feeling of well-being and immediate relaxation. A research is presented with a non-experimental design, from the quantitative approach of a cross-sectional comparative descriptive type. Its objective is to determine the relationships between physical activity and emotional regulation of a group of nurses from the Sur Hospital in Chilpancingo, Guerrero, Mexico. The TMMS-24 Emotional Intelligence Assessment Scale and the International Physical Activity Questionnaire (IPAQ) were applied. To determine the relationship between the variables, Spearman's Rho Correlation was used. The dimensions studied are attention, clarity and emotional repair by the dependent variable (Emotional Control) and the High, Medium and Low dimensions by the independent variable (Physical Activity). In the community where the signs and symptoms of nervousness, agitation or tension associated with situations of anxiety and stress were observed, direct correlations were established between the intensity of physical activity and the emotional control of the subjects studied, that is, at a lower intensity of physical activity, less control and emotional regulation.

RESUMO

Introducción: Los brotes recurrentes de dengue subrayan la necesidad de abordajes más efectivos en la prevención y control de vectores. A menudo, las intervenciones se centran en un enfoque biomédico y de promoción de la salud desde un enfoque individual, sin integrar factores socioambientales ni ser evaluados científicamente Objetivo: Evaluar el impacto de la recolección de residuos domésticos de gran tamaño sobre potenciales criaderos de mosquitos transmisores del dengue en Asunción, Paraguay durante los años 2017 a 2021. Material y métodos: Estudio cuasiexperimental, longitudinal, donde se encuestaron 350 hogares, como línea de base durante el 2017 y una línea de cierre en 108 hogares en 2021. Se utilizó el método de Diferencia en Diferencia (DID) para comparar la presencia de criaderos antes y después de la intervención en 43 hogares intervenidos y 65 no intervenidos. Resultados: La recolección diferenciada fue utilizada principalmente por aquellos hogares que tenían una gran cantidad de residuos sólidos de gran tamaño, pero no para deshacerse de todos estos objetos, sino sólo de una parte (DID de -52% en el número total de criaderos y DID de 1% en número de hogares con criaderos). Encontramos una reducción significativa en el número de total de criaderos de gran tamaño, pero no observamos diferencias en el número total de hogares con criaderos. Factores subjetivos, como la creencia de que los objetos en desuso podrían llegar a ser útiles en el futuro explicaban en gran medida su presencia en los hogares, incluso con el servicio disponible. Conclusiones: El enfoque de la gestión municipal en los residuos voluminosos puede contribuir a la prevención del dengue por el hecho de que no constituyen residuos de generación rápida en los hogares, y su eliminación puede tener un impacto relativamente duradero. El factor subjetivo relacionado con la presencia de estos criaderos en los hogares debe ser objeto de mayores estudios.


Introduction: Recurrent dengue outbreaks underscore the need for more effective approaches to vector prevention and control. Often, interventions focus on a biomedical and health promotion approach from an individual approach, without integrating socio-environmental factors or being scientifically evaluated. Objetive: To evaluate the impact of large household waste collection on potential breeding sites of dengue-transmitting mosquitoes in Asuncion, Paraguay during the years 2017 to 2021. Material and methods: Quasi-experimental, longitudinal study, where 350 households were surveyed, as a baseline during 2017 and a closing line in 108 households in 2021. The Difference-in-Difference (DID) method was used to compare the presence of breeding sites before and after the intervention in 43 intervened and 65 non-intervened households. Results: Differentiated collection was mainly used by those households that had a large amount of large solid waste, but not to dispose of all these objects, but only part of them (DID of -52% in the total number of breeding sites and DID of 1% in the number of households with breeding sites). We found a significant reduction in the total number of large breeding sites but did not observe differences in the total number of households with breeding sites. Subjective factors, such as the belief that disused objects could become useful in the future, were largely responsible for the reduction in the number of large breeding sites. Conclusions: The municipal management approach to bulky waste can contribute to dengue prevention because it does not constitute rapidly generated waste in households, and its disposal can have a relatively long-lasting impact. The subjective factors related to the presence of these breeding sites in households warrant further study.

RESUMO

BACKGROUND: Executive function (EF) deficits are a significant risk factor for falls among older adults (OAs). However, relationship between EF subdomains (shifting, updating, and inhibition), postural balance (PB), and fall risk in healthy OAs, remains poorly understood. OBJECTIVE: This study aimed to investigate the relationship between EF subdomains (shifting, updating, and inhibition) and PB, and to assess their impact on risk of falls in community-dwelling OAs. METHODS: A cross-sectional study involving 50 OAs aged over 60 years (average age of 72 years) was conducted. Participants underwent assessments of EF subdomains and PB using validated tests. A correlation analysis was employed to examine the relationships between EF and PB. RESULTS: The study revealed significant correlations between subdomains and PB. Mental set shifting (r = -.539; p < .001) and inhibition (r = -.395; p = .050) exhibited inverse relationships with PB. Stepwise multiple linear regression showed that Trail Making Test Part B was associated with the PB (R2 = .42, p < .001). CONCLUSION: These findings highlight the importance of assessing EF subdomains, particularly shifting and inhibition, to identify risk of falls. Trail Making Test Part B largely explains the variability of the PB. Integrating PB assessments and EF training, such as the Mini-BESTest, into routine care can be vital for fall prevention strategies. Significance/Implications: This knowledge underscores the need for cognitive training interventions focusing on shifting and inhibition to enhance PB and potentially reduce falls. Additionally, incorporation of EF assessment tools as Trail Making Test Part B and the Mini-BESTest into routine clinical practice for community-dwelling OAs is recommended to address fall prevention strategies.

RESUMO

Reciprocal inhibition and coactivation are strategies of the central nervous system used to perform various daily tasks. In automatic postural responses (APR), coactivation is widely investigated in the ankle joint muscles, however reciprocal inhibition, although clear in manipulative motor actions, has not been investigated in the context of APRs. The aim was to identify whether reciprocal inhibition can be observed as a strategy in the recruitment of gastrocnemius Medialis (GM), Soleus (So) and Tibialis Anterior (TA) muscles in low- and high-velocity forward and backward perturbations. We applied two balance perturbations with a low and a high velocity of displacement of the movable platform in forward and backward conditions and we evaluated the magnitude and latency time of TA, GM and So activation latency, measured by electromyography (EMG). In forward perturbations, coactivation of the three muscles was observed, with greater activation amplitude of the GM and lesser amplitude of the So and TA muscles. For backward, the pattern of response observed was activation of the TA muscle, a decrease in the EMG signal, which characterizes reciprocal inhibition of the GM muscle and maintenance of the basal state of the So muscle. This result indicates that backward perturbations are more challenging.

RESUMO

The presence of infective larvae (L3) of gastrointestinal nematode (GIN) parasites in pastures directly contributes to the constant recurrence of infections in ruminant herds. This study aimed to evaluate the nematophagous fungus Duddingtonia flagrans (AC001) (proteolytic crude extract and/or conidia) in the in vitro control of GIN L3 in coprocultures. To produce the proteolytic crude extract, a suspension (107 conidia/mL) of D. flagrans was inoculated into a liquid medium. After 6 days, the medium was filtered, centrifuged, and its proteolytic activity was measured. For the experimental assay, fecal samples were collected directly from the rectal ampulla of naturally infected sheep, and egg counts per gram of feces (EPG) were performed. Coprocultures were prepared using 10 g of fecal material with the groups defined as follows: control group G1 (1.0 mL of denatured proteolytic crude extract); treated group G2 (1.0 mL of active proteolytic crude extract); treated group G3 (1.0 mL of active proteolytic crude extract + 1.0 mL of AC001 conidia). The coprocultures were maintained at room temperature (25ºC), for 7 days, and then the L3 larvae were recovered. The results demonstrated that AC001 successfully produced protease (56.34 U/mL). The treatments with active proteolytic crude extract (G2) and active proteolytic crude extract + AC001 conidia (G3) were significantly different (p < 0.01) from the control group with denatured proteolytic crude extract (G1). AC001 and its proteolytic crude extract acted concomitantly on helminths directly in the fecal environment, suggesting potential future applications in the field.

RESUMO

BACKGROUND: In response to a 1995 outbreak of sepsis caused by multidrug-resistant (MR) Gram-negative bacteria (GNB), a Brazilian level III neonatal unit established a series of control and prevention measures. This study evaluated the long-term effects of these measures on late-onset neonatal sepsis (LONS) caused by MR bacteria from 2000 to 2020 and examined their impact on in-hospital mortality. METHODS: Newborns with LONS and positive cultures for Staphylococcus aureus, GNB, and Enterococcus sp were selected, adhering to Center for Desease Control and Prevention and local criteria. Joinpoint regression analysis was used to assess annual trends. RESULTS: Over the 21-year period, the overall LONS rate was 4.6%, showing a significant decline from 2000 to 2016 (P < .0001, slope -0.36). However, from 2016 to 2020, there was a non-significant increase in sepsis rates (slope +0.92, P = .08). MR sepsis were in 15.8% of sepsis cases and displayed a non-significant upward trend (slope +0.50, P = .08) with no major shifts. In-hospital mortality rates for MR and non-MR LONS showed no significant differences (P = .413). DISCUSSION: The study indicates a low prevalence of MR sepsis due to effective antimicrobial use and educational interventions. CONCLUSIONS: MR sepsis prevalence remained low and stable, not increasing in-hospital mortality.

RESUMO

BACKGROUND AND OBJECTIVES: The storage temperature of immunohaematological reagents generally ranges from 2 to 8°C, and they should be utilised at room temperature. This study aimed to analyse the stability of immunohaematological reagents used in ABO and RhD typing. METHODS: The evaluation encompassed the potency, specificity, and integrity of anti-A, anti-B, anti-D, RhD control sera, and A1 and B red blood cells (RBC) reagents after long (8 h) and short (4 h) daily periods of exposure to room temperature (20-24°C), 5 days a week for 4 weeks. Additionally, the A1 and B RBC reagents were exposed daily for 11 h and 30 min at room temperature, including 30 more minutes at room temperature with simultaneous homogenisation through equipment. For the control, an aliquot of each reagent was constantly stored at refrigeration temperature, while another was exposed to room temperature for 12 h daily. Tests conducted included reaction intensity, titration, and avidity for antisera, reaction intensity, free haemoglobin determination, and electrical conductivity for the RBC reagents. RESULTS: The antisera maintained the reaction intensity. The titre and avidity of the antisera satisfied the minimum Brazilian requirements after different exposure periods. A higher free haemoglobin concentration was noted in the RBC reagents subjected to room temperature and simultaneous homogenisation, although this did not affect the potency and specificity. The electrical conductivity average of the RBC reagent remained consistent. CONCLUSION: The findings indicate that the immunohaematological reagents from a specific manufacturer are stable under the tested temperature, ensuring the quality of the results under these conditions.

RESUMO

BACKGROUND: Wolbachia symbiosis in Aedes aegypti is an emerging biocontrol measure against dengue. However, assessing its real-world efficacy is challenging due to the non-randomised, field-based nature of most intervention studies. This research re-evaluates the spatial-temporal impact of Wolbachia interventions on dengue incidence using a large battery of quasi-experimental methods and assesses each method's validity. METHODS: A systematic search for Wolbachia intervention data was conducted via PUBMED. Efficacy was reassessed using commonly-used quasi-experimental approaches with extensive robustness checks, including geospatial placebo tests and a simulation study. Intervention efficacies across multiple study sites were computed using high-resolution aggregations to examine heterogeneities across sites and study periods. We further designed a stochastic simulation framework to assess the methods' ability to estimate intervention efficacies (IE). RESULTS: Wolbachia interventions in Singapore, Malaysia, and Brazil significantly decreased dengue incidence, with reductions ranging from 48.17% to 69.19%. IEs varied with location and duration. Malaysia showed increasing efficacy over time, while Brazil exhibited initial success with subsequent decline, hinting at operational challenges. Singapore's strategy was highly effective despite partial saturation. Simulations identified Synthetic Control Methods (SCM) and its variant, count Synthetic Control Method (cSCM), as superior in precision, with the smallest percentage errors in efficacy estimation. These methods also demonstrated robustness in placebo tests. CONCLUSIONS: Wolbachia interventions exhibit consistent protective effects against dengue. SCM and cSCM provided the most precise and robust estimates of IEs, validated across simulated and real-world settings.

RESUMO

BACKGROUND: Mosquito-borne diseases, such as malaria, dengue, Zika and chikungunya, pose significant public health threats in tropical and subtropical regions worldwide. To mitigate the impact of these diseases on human health, effective vector surveillance and control strategies are necessary. Traditional vector control methods, which rely on chemical agents such as insecticides and larvicides, face challenges such as resistance and environmental concerns. Consequently, there has been a push to explore novel surveillance and control tools. Mass trapping interventions have emerged as a promising and environmentally friendly approach to reducing the burden of mosquito-borne diseases. This study assessed mass-trapping interventions using autocidal gravid ovitraps (AGOs) on Aedes aegypti populations in Reynosa, Tamaulipas, Mexico. METHODS: Four neighborhoods were selected to evaluate the effects of three treatments: AGO mass-trapping, integrated vector control (IVC), which included source reduction and the application of chemical larvicide and adulticide, and AGO + IVC on Ae. aegypti populations. A control area with no interventions was also included. The effectiveness of the interventions was evaluated by comparing Ae. aegypti abundance between the pre-treatment period (9 weeks) and the post-treatment period (11 weeks) for each treatment. RESULTS: Only treatment using AGO mass trapping with an 84% coverage significantly reduced Ae. aegypti female populations by 47%, from 3.75 ± 0.32 to 1.96 ± 0.15 females/trap/week. As expected, the abundance of Ae. aegypti in the control area did not differ from the pre- and post-treatment period (range of 4.97 ± 0.59 to 5.78 ± 0.53); Ae. aegypti abundance in the IVC treatment was 3.47 ± 0.30 before and 4.13 ± 0.35 after, which was not significantly different. However, Ae. aegypti abundance in the AGO + IVC treatment increased from 1.43 ± 0.21 before to 2.11 ± 0.20 after interventions; this increase may be explained in part by the low AGO (56%) coverage. CONCLUSIONS: This is the first report to our knowledge on the effectiveness of mass-trapping interventions with AGOs in Mexico, establishing AGOs as a potential tool for controlling Ae. aegypti in Northeastern Mexico when deployed with sufficient coverage.

RESUMO

Aims: This study aimed to assess the use of glucometers by patients and the analytical performance of glucometers provided by the primary care services. Methods: The analytical performance of 48 glucometers Accu-Chek® Active, was assessed through quintuplicate analyses of one Roche and one PNCQ (National Quality Control Program) control sample at different concentrations; 31 were also evaluated by a single proficiency testing sample. The evaluation metrics included imprecision, bias, and total error and were measured according to quality specifications based on biological variation (QSBV). Glucometer users answered a questionnaire regarding their experience. Results: Among the 48 glucometers evaluated with internal control samples, 17 met precision criteria at both control levels according to QSBV, while 24 met the criteria at only one control level. Of the 31 glucometers further evaluated through proficiency test, 11 met accuracy criteria according to QSBV, and only one device showed an unacceptable result. Out of these 31, only 15 demonstrated a total error within the acceptable maximum limits based on QSBV. Conclusions: Overall, our findings showed that patients had a good understanding of glucometer usage and suggested that some glucometers should be replaced, as they sometimes failed to meet even the manufacturer's acceptable variation limits, and/or did not meet QSBV.

RESUMO

This article presents a direct method for temperature control in solid-state lasers, where temperature stability is crucial for optimizing the performance and reliability of such lasers. The proposed method utilizes Peltier chips for both cooling and heating the laser crystal to achieve precise temperature regulation. The system design is based on the step response of the open-loop thermal system and employs a proportional-integral (PI) controller for closed-loop temperature control. Comprehensive testing on a femtosecond Titanium-Sapphire Laser (Ti:Sapphire laser) demonstrated that the system is capable of maintaining the desired operating temperature with remarkable stability and efficiency, highlighting its practicality for real-world applications. Method Outline:•Utilization of Peltier chips for precise temperature control.•Estimation of first-order transfer function based on step response.•Implementation of a proportional-integral (PI) controller for closed-loop temperature regulation.

RESUMO

Little is known about winter-season parasitism of eggs of the corn leafhopper Dalbulus maidis DeLong (Hemiptera: Cicadellidae), an important pest of maize throughout the Americas. Our study, conducted in Mexico, aimed to characterize winter-season parasitism of corn leafhopper eggs on maize crops cultivated with drip irrigation and on wild grasses that grow on the edges of maize crops when maize is not present. Maize leaves baited with D. maidis eggs were used to trap the egg parasitoids in the field. In the first year (2022), parasitism of D. maidis eggs was investigated in maize fields planted contiguously on different dates (asynchronous planting). In the second year (2023), parasitism of D. maidis eggs was evaluated in edge grasses and in adjacent maize crops planted on the same date (synchronous). The highest percentage of parasitism (53%), percentage of emergence, and total abundance of egg parasitoids were found in asynchronous maize fields. Here, Anagrus virlai Triapitsyn (Hymenoptera: Mymaridae), Paracentrobia subflava (Girault) (Hymenoptera: Trichogrammatidae), and Pseudoligosita sp. (Hymenoptera: Trichogrammatidae) wasps were found parasitizing the D. maidis eggs, with P. subflava being the most abundant. In wild edge grasses, only P. subflava was found, showing low levels of parasitism, while in synchronous maize, P. subflava increased its percentage of parasitism (up to 37%), percentage of emergence, and abundance, during winter. These results suggest that P. subflava acts as an efficient biological control agent of D. maidis in irrigation-grown maize crops during the winter season, and that edge grasses are overwinter habitats for P. subflava.

RESUMO

The bacterial community from a cooling water system was investigated through culture-dependent and independent strategies, and the responses of planktonic and sessile bacteria (grown in glass slides and stainless-steel coupons) to antimicrobials of industrial and clinical use were assessed. The morphotypes with higher biofilm-forming potential were Pseudoxanthomonas sp., Rheinheimera sp., Aeromonas sp. and Staphylococcus sp., and the first also exhibited lower susceptibility to all antibiotics and biocides tested. 16S rRNA high throughput sequencing indicated that Pseudomonadota (77.1% on average, sd 11.1%), Bacteroidota (8.4, sd 5.7%), and Planctomycetota (3.0, sd 1.3%) were the most abundant phyla. KEGG orthologs associated with antibiotics and biocide resistance were abundant in all samples. Although the minimum inhibitory and bactericidal concentrations were generally higher for biofilms, morphotypes in planktonic form also showed high levels of resistance, which could be associated with biofilm cells passing into the planktonic phase. Overall, monochloramine was the most effective biocide.

RESUMO

BACKGROUND: Psoriasis is a common immune-mediated skin disease that can involve other organs and tissues, including the oral mucosa. Some studies have found an increased proportion of geographic tongue (GT) and fissured tongue (FT) in patients with psoriasis, which appears to be region-specific. OBJECTIVES: The association of psoriasis with GT/FT in Eastern Asian populations remains unknown. Thus, the authors aimed to investigate the association of psoriasis with GT/FT in the Han population in southwestern China. METHODS: This study was conducted on 230 psoriatics and 230 healthy controls at West China Hospital. The authors compared the proportion of subjects with GT/FT in the two groups and compared age, gender, smoking, alcohol consumption, age at onset of psoriasis, duration of psoriasis, nail and joint involvement, Psoriasis Area and Severity Index, Body Surface Area, Dermatology Life Quality Index, and proportion using biologics in psoriatics with or without GT /FT. RESULTS: The authors have found a strong association between psoriasis and FT (p < 0.001), and a non-significant association between psoriasis and GT (p = 0.760). Compared to psoriasis patients without FT, the authors found that psoriasis patients with FT were older (p = 0.021) and had an increased frequency of late-onset psoriasis (p = 0.014); they also had more severe psoriasis (p = 0.047) and poorer quality of life (p = 0.045). STUDY LIMITATIONS: GT has periods of exacerbation and remission, so the authors cannot avoid a deviation of the prevalence of GT in this study from the true prevalence rate. Also, biologics have been found to lead to remission of GT and FT, which may have influenced the GT/FT ratio in the case group in this study. CONCLUSIONS: Psoriasis was associated with FT in the Han population in southwestern China, attention must be paid to the treatment of psoriatics with FT and skin diseases in patients with FT.

RESUMO

INTRODUCTION: Type 2 diabetes is a major public health issue in Mexico due to its high prevalence and its projection for the coming years for this disease. Findings on multidisciplinary care related to chronic diseases have proven effective, based on measurement of patient-centered outcomes, The Center of Comprehensive Care for Patients with Diabetes (CAIPaDi) is a multidisciplinary program focused on reducing diabetes complications. This case study aims to illustrate the results of implementing health outcomes measurements and demonstrate the beneficial effects of establishing a comprehensive model of care through a patient-centered approach. METHODS: A descriptive analysis of the comprehensive care indicators of patients with type 2 diabetes treated in the CAIPaDi program between 2013 and 2023 was conducted. The results were structured according to the standard set of outcomes for diabetes proposed by the International Consortium for Health Outcomes Measurements (ICHOM). RESULTS: The baseline and prospective registration of consultations was completed for five years, complying with 25 of the 26 indicators of the ICHOM set. In diabetes control, 56.5% of patients had A1c ≤ 7%, 87.9% had BP ≤ 130/80 mmHg, 60.9% had LDL-cholesterol < 100 mg/dl, and obesity rates decreased from 42.19% to 30.6% during annual consultations. Fewer years of diagnosis before the first visit is key to overall improvement in program adherence (P = 0.02). In acute events, a hyperglycemic crisis occurred in only two cases and severe hypoglycemia episodes in 8 patients. For chronic complications, no lower limb amputations occurred. Cardiovascular outcomes occurred in < 1%. Periodontal disease was analyzed, and periodontitis decreased from 82.9% to 78.7%. Mortality reports were low, with COVID-19 being the main cause of death. Patient-reported outcomes demonstrated reductions in anxiety, depression, and diabetes distress during follow-up. CONCLUSION: Registering quality-of-care indicators is feasible in a comprehensive care program. It allows improving the medical, mental health, and lifestyle outcomes of patients with type 2 diabetes and provides relevant data for planning health programs. A quick diagnosis before program adherence is crucial for overall improvement in patients.

RESUMO

OBJECTIVE: The aim of the present study was to identify the risk factors for severe maternal outcomes (SMO) of women with suspected or confirmed infections using the data from the WHO global maternal sepsis study (GLOSS). METHODS: We conducted a secondary analysis of the GLOSS cohort study, which involved pregnant or recently pregnant women with suspected or confirmed infection around 713 health facilities in 52 low- and middle-income countries, and high-income countries. A nested case-control study was conducted within the GLOSS cohort. Cases included infection-related maternal deaths or near misses, while controls represented non-SMO. Logistic mixed models, adjusting for country variations, were employed. Using univariate analysis, we calculated crude odds ratios (crude OR) and their 95% confidence interval (95% CI). Variables were identified with less than 16% missing data, and P values less than 0.20 were used to perform the multivariate logistic model multilevel. RESULTS: A total of 2558 women were included in the analysis. As for the cases, 134 patients were found in the pregnant in labor or not in labor group and 246 patients in the postpartum or postabortion group. Pregnant women with prior childbirths faced a 64% increased risk of SMO. Ante- or intrapartum hemorrhage increased risk by 4.45 times, while trauma during pregnancy increased it by 4.81 times. Pre-existing medical conditions elevated risk five-fold, while hospital-acquired infections increased it by 53%. Secondary infections raised risk six-fold. Postpartum/postabortion women with prior childbirths had a 45% elevated risk, and pre-existing medical conditions raised it by 2.84 times. Hospital-acquired infections increased risk by 93%. Postpartum hemorrhage increased risk approximately five-fold, while abortion-related bleeding doubled it. Previous cesarean, abortion, and stillbirth also elevated risk. CONCLUSIONS: Key risk factors for SMO include prior childbirths, hemorrhage, trauma, pre-existing conditions, and hospital-acquired or secondary infections. Implementing effective alert systems and targeted interventions is essential to mitigate these risks and improve maternal health outcomes, especially in resource-limited settings.

RESUMO

BACKGROUND: In dental extractions, particularly when local anesthesia is used, it usually offers analgesic relief for a few hours. However, pain can become a notable concern in the immediate postoperative period due to the trauma experienced by both soft and hard oral tissues. OBJECTIVES: This systematic review aimed to evaluate the most effective strategies for managing postoperative pain in primary tooth extractions. METHODS: Two examiners conducted a search across five electronic databases: MEDLINE (via PubMed), Embase, Scopus, Web of Science, CENTRAL, and OpenGray. Studies were included if they met the following criteria after reviewing their titles and abstracts: they involved children and evaluated pain management following primary tooth extraction. Subsequently, articles that described extractions performed under any form of sedation, were not conducted under local anesthesia, in an outpatient setting, and in children aged 0 to 12 years, or were not randomized controlled trials, were excluded. RESULTS: The search yielded 374 relevant articles, of which 9 were included. Among these, 5 utilized preoperative medications as a pain management strategy, one evaluated low-level laser therapy (LLLT) postoperatively, one assessed calendula drops postoperatively, and another explored virtual reality during the procedure and arnica in solution both pre and postoperatively. CONCLUSION: Among all the strategies evaluated, the strategy involving analgesics administered 30 minutes before tooth extractions was supported by better-designed studies. However, there is a high risk of bias.
