RESUMO

The E6 and E7 oncoproteins of high-risk types of human papillomavirus (HR-HPV) are crucial for the development of cervical cancer (CC). Small interfering RNAs (siRNAs) are explored as novel therapies that silence these oncogenes, but their clinical use is hampered by inefficient delivery systems. Modification (pegylation) with polyethylene glycol (PEG) of liposomal siRNA complexes (siRNA lipoplexes) may improve systemic stability. We studied the effect of siRNA targeting HPV16 E6, delivered via cationic liposomes (lipoplexes), on cellular processes in a cervical carcinoma cell line (CaSki) and its potential therapeutic use. Lipoplexes-PEG-HPV16 E6, composed of DOTAP, Chol, DOPE, and DSPE-PEG2000 were prepared. The results showed that pegylation (5% DSPE-PEG2000) provided stable siRNA protection, with a particle size of 86.42 ± 3.19 nm and a complexation efficiency of over 80%; the siRNA remained stable for 30 days. These lipoplexes significantly reduced HPV16 E6 protein levels and restored p53 protein expression, inhibiting carcinogenic processes such as proliferation by 25.74%, migration (95.7%), and cell invasion (97.8%) at concentrations of 20 nM, 200 nM, and 80 nM, respectively. In conclusion, cationic lipoplexes-PEG-HPV16 E6 show promise as siRNA carriers for silencing HPV16 E6 in CC.

RESUMO

Resumen Antecedentes: Los aneurismas de la aorta ascendente son patologías poco frecuentes en la infancia, sobre todo en ausencia de enfermedades previas como el síndrome de Marfan. Objetivo: Dar a conocer la posibilidad del manejo endovascular exitoso de los aneurismas de grandes vasos, usando stent y micro catéter con embolización del saco aneurismático. Método: Presentamos el caso de una paciente de 10 años y 2 meses, previamente sana, en quien se documentó un pseudoaneurisma entre el origen de la arteria carótida común izquierda y la arteria subclavia izquierda, que logró manejarse de forma endovascular, inicialmente con un stent cubriendo el cuello del aneurisma con el fin de remodelarlo y posteriormente por medio de microcatéter se realizó embolización del saco del aneurisma con coils, con resultado exitoso. Resultados: Los aneurismas de los grandes vasos, como la arteria carótida común y la arteria subclavia, tienen riesgo de ruptura con complicaciones devastadoras; el manejo endovascular se plantea como una opción poco invasiva de manejo, con resultados favorables. Conclusión: El manejo de aneurismas de grandes vasos, por vía endovascular usando stent y microcatéter con embolización del saco aneurismático, es una opción novedosa de manejo que logra resultados exitosos.


Abstract Background: Ascending aortic aneurysms are rare pathologies in childhood, especially in the absence of previous diseases such as Marfan syndrome. Objective: Present the possibility of successful endovascular management of large vessel aneurysms, using stents and microcatheters with embolization of the aneurysm sac. Method: We present the case of a previously healthy ten-year-old patient, in whom a pseudoaneurysm was documented between the origin of the left common carotid artery and left subclavian artery, successfully managed endovascularly, initially with a stent covering the neck of the aneurysm to remodel it and later with embolization of the aneurysm sac using a microcatheter. Results: Aneurysms of large vessels, such common carotid artery and subclavian artery, are at risk of rupture with devastating complications; endovascular management is considered a minimally invasive management option, with favorable results. Conclusion: The endovascular management of large vessel aneurysms using stents and microcatheters with embolization of the aneurysmal sac is a novel management option that achieves successful results.

RESUMO

Background: L-2-hydroxyglutaric aciduria (L2HGA) is a rare inherited autosomal recessive neurometabolic disorder caused by pathogenic variants in the L2HGDH gene which encodes mitochondrial 2-hydroxyglutarate dehydrogenase. Here, we report a case of L2HGA in a Mexican-Mayan patient with a homozygous mutation at L2HGDH gene and clinical response to vitamin supplements and levocarnitine. Case report: A 17-year-old, right-handed female patient with long-term history of seizures, developmental delay and ataxia was referred to a movement disorders specialist for the evaluation of tremor. Her brain MRI showed typical findings of L2HGA. The diagnosis was corroborated with elevated levels of 2-hydroxyglutaric acid in urine and genetic test which revealed a homozygous genetic known variant c.569C>T in exon 5 of L2HGDH gene. She was treated with levocarnitine and vitamin supplements, showing improvement in tremor and gait. Discussion: To our knowledge this is the first report of a Mexican patient with L2HGA. This case adds information about a rare condition in a different ethnic group and supports the findings of other authors which encountered symptomatic improvement with the use of flavin adenine dinucleotide (and its precursor riboflavin), and levocarnitine. Highlights: We report the first case of Mexican-Mayan patient with L2HGA showing a missense homozygous mutation in L2HGDH gene, and improvement of symptoms with vitamin supplements and levocarnitine.

RESUMO

BACKGROUND: Aneurysms and diverticula of the left ventricle are rare entities in childhood, with a prevalence of less than 0.1%. Described since 1886, as a severe and potentially fatal disease if not corrected, mainly due to the presence of associated anomalies and the risk of rupture. OBJETIVE: Present other management options for ventricular diverticula, different from surgical options, using alternative materials that are not used very often in daily practice. METHOD: A detailed description of a case successfully managed with these new treatment modalities. RESULTS: Endovascular management of the left ventricular diverticulum, diagnosed prenatally in the patient presented, was successful after initial failure with surgical management. CONCLUSIONS: Endovascular management of ventricular diverticula, using alternative materials to those commonly used, is an attractive option with satisfactory results in these patients.

RESUMO

Pneumocystis is an opportunistic fungus that causes potentially fatal pneumonia (PCP) in immunocompromised patients. The objective of this study was to determine the prevalence of P. jirovecii in HIV patients through phenotypic and molecular study, to investigate the genetic polymorphisms of P. jirovecii at the mitochondrial gene mtLSU and at the nuclear dihydropteroate synthase gene (DHPS), and by analysis of molecular docking to study the effect of DHPS mutations on the enzymatic affinity for sulfamethoxazole. A PCP prevalence of 28.3% was detected, with mtLSU rRNA genotypes 3 (33.3%) and 2 (26.6%) being the most common. A prevalence of 6.7% (1/15) mutations in the DHPS gene was detected, specifically at codon 55 of the amino acid sequence of dihydropteroate synthase. Molecular docking analysis showed that the combination of mutations at 55 and 98 codons is required to significantly reduce the affinity of the enzyme for sulfamethoxazole. We observed a low rate of mutations in the DHPS gene, and molecular docking analysis showed that at least two mutations in the DHPS gene are required to significantly reduce the affinity of dihydropteroate synthase for sulfamethoxazole.

RESUMO

INTRODUCCIÓN: El Compromiso Organizacional (CO), se considera un vínculo entre la organización y los trabajadores, e influye en la satisfacción, el desempeño, la productividad y la inversión profesional. OBJETIVO: Determinar el compromiso organizacional en profesionales y técnicos en enfermería adscritos a un hospital del sur de chile, años 2022-2023. METODOLOGÍA: Estudio de corte transversal, en una muestra de 305 funcionarios. La recolección de la información se realizó con el instrumento compromiso organizacional de Meyer y Allen (1991), puntuación según escala Likert de 5 puntos, donde 1 corresponde a "totalmente en desacuerdo" y 5 es "totalmente de acuerdo"; análisis con estadística descriptiva e inferencial. Estudio autorizado por el Comité de ética científica. RESULTADOS: El instrumento logró consistencia interna adecuada, mediante alfa de Cronbach. El CO observado fue "neutral o indiferente" con tendencia a "de acuerdo", según escala Likert. El Compromiso Afectivo (CA) fue superior respecto a los demás dominios. El Compromiso Normativo (CN) del nivel técnico mostró ser fuerte, así como los funcionarios divorciados y viudos. El Compromiso de Continuidad (CC) resultó ser el dominio con promedio más bajo. A mayor edad, aumentó el CA. CONCLUSIONES: los funcionarios mostraron un nivel medio de compromiso organizacional con tendencia a alto, por lo que se debe fortalecer el lazo afectivo del binomio funcionario/organización, de manera que juegue un papel positivo en la calidad de la atención otorgada hacia sus usuarios.


INTRODUCTION: Organizational Commitment (OC) is considered a crucial link between an organization and its employees, significantly impacting satisfaction, performance, productivity, and professional investment. OBJECTIVE: To assess organizational commitment among nursing professionals and technicians in a hospital in southern Chile between 2022 and 2023. METHODOLOGY: This was a cross-sectional study involving a sample of 305 staff members. Data collection utilized Meyer and Allen's (1991) Organizational Commitment tool, employing a 5-point Likert scale where 1 signifies "completely disagree" and 5 indicates "completely agree." Analysis encompassed descriptive and inferential statistics. RESULTS: The instrument demonstrated sound internal consistency, supported by Cronbach's alpha. Observed OC tended towards a "neutral or indifferent" stance with a leaning towards "agreement" on the Likert scale. Affective Commitment (AC) exhibited higher levels compared to other domains. Normative Commitment (NC) among technical-level employees were robust, and particularly notable among divorced and widowed staff. Continuance Commitment (CC) emerged as the domain with the lowest average. AC showed an increase with age. CONCLUSIONS: Staff exhibited a moderate level of organizational commitment with a propensity towards a higher level, suggesting the need to reinforce the emotional bond between employees and the organization to positively influence the quality of care provided.

RESUMO

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

RESUMO

Resumen Objetivo: Determinar la latencia diagnóstica en la enfermedad de Parkinson (EP), así como su relación con variables clínicas y demográficas. Determinar la percepción de síntomas no motores: disfunción olfatoria, trastorno conductual del sueño MOR, depresión y estreñimiento, previos al diagnóstico de EP. Materiales y métodos: Estudio transversal realizado en Yucatán, México en sujetos con EP. Se analizó la asociación entre la latencia diagnóstica con variables clínicas y demográficas usando las pruebas estadísticas no paramétricas: U de Mann Whitney y Kruskal-Wallis. Resultados: Se incluyeron un total de 60 sujetos con una edad promedio de 66.7 años. El tiempo promedio transcurrido desde el inicio del primer síntoma motor hasta el diagnóstico fue de 20.8 meses. El tener antecedentes familiares de EP se asoció significativamente (p=0.031) con una latencia diagnóstica más prolongada en comparación con aquellos pacientes que no refirieron familiares con EP. En cualquier momento antes del diagnóstico de EP: el 36.6% de los pacientes percibieron estreñimiento, 15% depresión, 13.3% trastorno conductual del sueño MOR y 11.6% disfunción olfatoria, 51.7% no refirió ninguno. Conclusiones: La latencia diagnóstica promedio de un grupo de 60 pacientes con EP diagnosticados en Yucatán fue de 20.8 meses. La latencia diagnóstica no se asoció significativamente con el tipo de servicio médico de neurología que realizó en diagnóstico de EP (público o privado), ni con otras variables clínicas ni demográficas además del antecedente familiar de EP.


Abstract Objective: To determine the diagnostic latency in Parkinson's disease (PD), and its relationship with clinical and demographic variables. To determine the perception of non-motor symptoms: olfactory dysfunction, REM sleep behavior disorder, depression, and constipation, prior to the diagnosis of PD. Materials and methods: Cross-sectional study conducted in Yucatan, Mexico in subjects with PD. The association between diagnostic latency with clinical and demographic variables was analyzed using the non-parametric statistical tests: Mann Whitney U and Kruskal-Wallis. Results: A total of 60 subjects with a mean age of 66.7 years were included. The average time elapsed from the onset of the first sympoton to diagnosis was 20.8 months. A family history of PD was significantly associated (p=0.031) with a longer diagnostic latency compared to those patients who did not have relatives with PD. Before the diagnosis of PD: 36.6% of the patients perceived constipation, 15% depression, 13.3% REM sleep behavior disorder and 11.6% olfactory dysfunction, 51.7% did not report any. Conclusions: The mean diagnostic latency of a group of 60 patients with PD diagnosed in Yucatan was 20.8 months. Diagnostic latency was not significantly associated with the type of neurological medical service that performed the diagnosis (public or private), or with other clinical or demographic variables in addition to a family history of PD.

RESUMO

Common bean (Phaseolus vulgaris L.) is an important crop for food security and for national economics for several countries worldwide. One of the most important factors of risk in common bean production is the fungal disease anthracnose caused by Colletotrichum lindemuthianum, which, in some cases, causes complete yield losses; this kind of plant disease is usually managed through the application of chemical products such as fungicides that are commonly not accepted by society. This rejection is based on the relationship of pesticides with health damage and environmental contamination. In order to help in solving these drawbacks, the present work proposes the use of electrochemically activated salt solutions (EASSs) as a safer pathogen control agent in crops, due to it having shown an elicitor and biostimulant effect on plants. With this background, this manuscript presents in vitro results of the evaluation of the inhibitory effect for multiple bean pathogens and in vivo results of EASS in the common bean-Colletotrichum pathosystem by evaluation of the infection severity and defense activation, such as secondary metabolite production and antioxidant activity. EASS presence in growth media had a strong inhibitory effect at the beginning of experiments for some of the evaluated fungi. EASSs showed an effect against the development of the disease when applied in specific doses to prevent distress in plants.

RESUMO

The objective of this work was to molecularly and genotypically characterize and test the inhibitory activity of six colicinogenic Escherichia coli strains (ColEc) and their partially purified colicins against STEC O157:H7 isolated from clinical human cases. Inhibition tests demonstrated the activity of these strains and their colicins against STEC O157:H7. By PCR it was possible to detect colicins Ia, E7, and B and microcins M, H47, C7, and J25. By genome sequencing of two selected ColEc strains, it was possible to identify additional colicins such as E1 and Ib. No genes coding for stx1 and stx2 were detected after analyzing the genome sequence. The inhibitory activity of ColEc against STEC O157:H7 used as an indicator showed that colicins are potent growth inhibitors of E. coli O157:H7, being a potential alternative to reduce the presence of pathogens of public health relevance.

RESUMO

Background: The capillary blood glucose monitoring program at home a challenge in primary health care. Therefore, it is fundamental to identify the glycemic control of people with diabetes mellitus through HBA1c and to analyze its associated factors. Objective: To identify the glycemic profile of people with Diabetes Mellitus (DM) through HbA1c and analyze factors associated. Materials & methods: Cross-sectional study developed in Ribeirão Preto, São Paulo, Brazil. Secondary data from the electronic health record of people registered in the Primary Health Care system were used. A sample of 3181 participants was obtained. People with HbA1c < 7.0% (53 mmol/mol) were considered to have adequate glycemic control. For people aged ≥ 55 years, a less stringent target, < 8.0% (64 mmol/mol), was also considered. The odds ratio was the measure of effect analyzed with their respective 95% Confidence Intervals (95% CI). Results: Adequate glycemic control with HbA1c < 7.0% (53 mmol/mol) was found in 44.8% of people and, when using the less rigid target, HbA1c < 8.0% (64 mmol/mol) for people aged ≥ 55 years-old, 70.6% had adequate glycemic control. Age and drug therapy were associated with adequate glycemic control (p < 0.001), which was more frequent among older people and those who used only metformin. Conclusion: The study shows that the achievement of adequate glycemic control is still a challenge, especially with regard to younger people and those who use insulin.

RESUMO

Background: Skin and soft tissue infections are one of the main causes of consultations worldwide. The objective was to determine the treatment of a group of patients with uncomplicated skin and soft tissue infections in Colombia. Methods: Follow-up study of a cohort of patients with skin infections who were treated in the Colombian Health System. Sociodemographic, clinical and pharmacological variables were identified. Treatments were evaluated using clinical practice guidelines for skin infections. Results: A total of 400 patients were analyzed. They had a median age of 38.0 years and 52.3% were men. The most commonly used antibiotics were cephalexin (39.0%), dicloxacillin (28.0%) and clindamycin (18.0%). A total of 49.8% of the subjects received inappropriate antibiotics, especially those with purulent infections (82.0%). Being cared for in an outpatient clinic (OR: 2.09; 95% CI: 1.06-4.12), presenting pain (OR: 3.72; 95% CI: 1.41-9.78) and having a purulent infection (OR: 25.71; 95% CI: 14.52-45.52) were associated with a higher probability of receiving inappropriate antibiotics. Conclusions: Half of patients with uncomplicated skin and soft tissue infections were treated with antibiotics that were not recommended by clinical practice guidelines. This inappropriate use of antibiotics occurred in the vast majority of patients with purulent infections because the antimicrobials used had no effect on methicillin-resistant Staphylococcus aureus.

RESUMO

Sweet peppers are consumed worldwide, and traditional uses have sparked interest in their applications as dietary antioxidants, which can be enhanced in plants using elicitors. These are endowed with phytochemicals with potential health benefits such as antioxidants, bioavailability, and bioaccessibility. The trend in metabolomics shows us chemical fingerprints linking metabolomics, innovative analytical form, and bioinformatics tools. The objective was to evaluate the impact of multiple stress interactions, elicitor concentrations, and electrical conductivity on the concentration of secondary metabolites to relate their response to metabolic pathways through the foliar application of a cocktail of said elicitors in pepper crops under greenhouse conditions. The extracts were analyzed by spectrophotometry and gas chromatography, and it was shown that the PCA analysis identified phenolic compounds and low molecular weight metabolites, confirming this as a metabolomic fingerprint in the hierarchical analysis. These compounds were also integrated by simultaneous gene and metabolite simulants to obtain effect information on different metabolic pathways. Showing changes in metabolite levels at T6 (36 mM H2O2 and 3.6 dS/m) and T7 (0.1 mM SA and 3.6 dS/m) but showing statistically significant changes at T5 (3.6 dS/m) and T8 (0.1 mM SA, 36 mM H2O2, and 3.6 dS/m) compared to T1 (32 dS/m) or control. Six pathways changed significantly (p < 0.05) in stress-induced treatments: aminoacyl t-RNA and valine-leucine-isoleucine biosynthesis, and alanine-aspartate-glutamate metabolism, glycoxylate-dicarboxylate cycle, arginine-proline, and citrate. This research provided a complete profile for the characterization of metabolomic fingerprint of bell pepper under multiple stress conditions.

RESUMO

Propolis collected by stingless bees is a valuable biocultural resource and a source of bioactive compounds. Methodologies to establish both the geographic origin and the potential pharmacological activity of propolis of stingless bees are required to regulate their sustainable use. The aim of this study was to classify Melipona beecheii propolis according to its phenolic compound content and potential pharmacological activity, using in vitro assays and statistical methodologies of multivariate analysis, hierarchical cluster analysis, and principal component analysis. Propolis samples were collected from seven states in southeastern Mexico. Total phenolic content and flavonoids were determined spectrophotometrically, and antioxidant, anti-inflammatory, and antimicrobial activities were evaluated. Both total phenolic content and flavonoids, and in vitro bioactivity potential of propolis extracts showed significant variations. Multivariate analysis, hierarchical cluster analysis, and principal component analysis enabled us to distinguish and classify propolis produced by M. beecheii according to similarity in terms of total phenolic content, in vitro bioactivity potential, and geographical origin. This strategy could be used to establish regulations for sustainable use, marketing, and industrial applications.

RESUMO

PURPOSE: To evaluate the effect of reconstruction and noise removal algorithms on the accuracy and precision of iodine concentration (CI) quantified with subtracted micro-computed tomography (micro-CT). PROCEDURES: Two reconstruction algorithms were evaluated: a filtered backprojection (FBP) algorithm and a simultaneous iterative reconstruction technique (SIRT) algorithm. A 3D bilateral filter (BF) was used for noise removal. A phantom study evaluated and compared the image quality, and the accuracy and precision of CI in four scenarios: filtered FBP, filtered SIRT, non-filtered FBP, and non-filtered SIRT. In vivo experiments were performed in an animal model of chemically-induced mammary cancer. RESULTS: Linear relationships between the measured and nominal CI values were found for all the scenarios in the phantom study (R2 > 0.95). SIRT significantly improved the accuracy and precision of CI compared to FBP, as given by their lower bias (adj. p-value = 0.0308) and repeatability coefficient (adj. p-value < 0.0001). Noise removal enabled a significant decrease in bias in filtered SIRT images only; non-significant differences were found for the repeatability coefficient. The phantom and in vivo studies showed that CI is a reproducible imaging parameter for all the scenarios (Pearson r > 0.99, p-value < 0.001). The contrast-to-noise ratio showed non-significant differences among the evaluated scenarios in the phantom study, while a significant improvement was found in the in vivo study when SIRT and BF algorithms were used. CONCLUSIONS: SIRT and BF algorithms improved the accuracy and precision of CI compared to FBP and non-filtered images, which encourages their use in subtracted micro-CT imaging.

RESUMO

Recently, the interest of consumers regarding artisan cheeses worldwide has increased. The ability of different autochthonous and characterized lactic acid bacteria (LAB) to produce aromas and the identification of the volatile organic compounds (VOCs) responsible for flavor in cheeses are important aspects to consider when selecting strains with optimal aromatic properties, resulting in the diversification of cheese products. The objective of this work is to determine the relationship between VOCs and microorganisms isolated (Lacticaseibacillus paracasei, Lactiplantibacillus plantarum, Leuconostoc mesenteroides and Lactococcus lactis subsp. hordniae) from raw sheep milk cheeses (matured and creamy natural) using accuracy and alternative methods. On combining Sanger sequencing for LAB identification with Gas Chromatography coupled to Ion Mobility Spectrometry (GC−IMS) to determinate VOCs, we describe cheeses and differentiate the potential role of each microorganism in their volatilome. The contribution of each LAB can be described according to their different VOC profile. Differences between LAB behavior in each cheese are shown, especially between LAB involved in creamy cheeses. Only L. lactis subsp. hordniae and L. mesenteroides show the same VOC profile in de Man Rogosa and Sharpe (MRS) cultures, but for different cheeses, and show two differences in VOC production in skim milk cultures. The occurrence of Lactococcus lactis subsp. hordniae from cheese is reported for first time.

RESUMO

OBJECTIVE: To compare the effectiveness of pain neuroscience education (PNE) versus biomedical education (BME) in a rehabilitation program following arthroscopic rotator cuff repair (ARCR) in patients with chronic shoulder pain. METHODS: Twenty-nine patients who participated in a rehabilitation program were randomly assigned to either an experimental PNE group (N = 16) or a control BME group (N = 13). Measurements included pain intensity at rest and in movement, pain catastrophizing, kinesiophobia, disability and health-related quality of life (HRQoL). Outcomes were evaluated at baseline and at 4 and 8 weeks after the intervention. RESULTS: A main effect for time was observed for: intensity of pain at rest (p < .01); pain with movement (p < .01); pain catastrophizing (p < .01); kinesiophobia (p < .01); disability (p < .01); and HRQoL (p < .01). No group interactions were significant for any variable, except for pain with movement, which favored the PNE group (p = .03). Large effect sizes (ranging from d = 0.79 to d = 2.65) were found for both interventions in all outcomes. CONCLUSION: A rehabilitation program including either PNE or BME are equally effective in improving rest pain, pain catastrophizing, kinesiophobia, disability, and HRQoL in patients after ARCR, except for pain at movement in favor of the PNE group. The inclusion of PNE in the rehabilitation program appears to lead to clinically meaningful improvements in pain at rest in short term when treating patients with ARCR.

RESUMO

A Automonitoramento da Glicemia Capilar (AMGC) é importante ferramenta no controle da glicemia e no manejo do Diabetes mellitus (DM) e os protocolos de dispensação de insumos são orientados por diretrizes de tratamento e regulamentações específicas. O objetivo desse estudo infodemiológico foi analisar as publicações na internet brasileira sobre protocolos AMGC por Secretarias Municipais e/ou Estaduais de saúde disponíveis em websites brasileiros. Para a busca foi utilizada a ferramenta Google e identificadas 286 URL. A pesquisa identificou 23 protocolos disponíveis em sites governamentais, revelando sendo que 10 (43,47%) são da região Sudeste, todos os protocolos definiram o diagnóstico de Diabetes mellitus (DM) tipo 1, DM tipo 2 em uso de insulina e DM gestacional (DMG), em 11 protocolos (47.8%) o fornecimento mensal de tiras de glicemia capilar é realizado pela farmácia e a quantidade variou de 30 até 120 tiras conforme o tipo de diabetes e uso de insulina. Os protocolos analisados enfatizam a importância da educação em DM, com 60,8% deles incorporando programas educacionais. Apesar da dinamicidade da informação na internet ressaltase a necessidade de transparência nos critérios de inclusão e manutenção do fornecimento das TGC, qualificando o cuidado ao paciente com DM. A elaboração e divulgação de protocolos fortalecem a transparência do SUS, auxiliam na organização dos fluxos de documentos entre os profissionais envolvidos e o acesso equitativo aos insumos.


Self-Monitoring of Blood Glucose (SMBG) is an important tool in controlling blood glucose and managing Diabetes mellitus (DM) and input dispensing protocols are guided by treatment guidelines and specific regulations. The objective of this infodemiological study was to analyze publications on the Brazilian internet about SMBG protocols by Municipal and/or State Health Departments available on Brazilian websites. For the search, the Google tool was used and 286 URLs were identified. The research identified 23 protocols available on government websites, revealing that 10 (43.47%) are from the Southeast region, all protocols defined the diagnosis of Diabetes mellitus (DM) type 1, type 2 DM using insulin and gestational DM (GDM), in 11 protocols (47.8%) the monthly supply of capillary blood glucose test strips is provided by the pharmacy and the quantity varies from 30 to 120 strips depending on the type of diabetes and insulin use. The protocols analyzed emphasize the importance of DM education, with 60.8% of them incorporating educational programs. Despite the dynamics of information on the internet, the need for transparency in the inclusion criteria and maintenance of the supply of BGTS is highlighted, qualifying care for patients with DM. The development and dissemination of protocols strengthens the transparency of the SUS, assists in the organization of document flows between the professionals involved and equitable access to inputs.
