RESUMO
AIM: To update the competences and learning outcomes and their evaluation, educational methods and education quality assurance for the training of contemporary specialists in periodontology, including the impact of the 2018 Classification of Periodontal and Peri-implant Diseases and Conditions (2018 Classification hereafter) and the European Federation of Periodontology (EFP) Clinical Practice Guidelines (CPGs). METHODS: Evidence was gathered through scientific databases and by searching for European policies on higher education. In addition, two surveys were designed and sent to program directors and graduates. RESULTS: Program directors reported that curricula were periodically adapted to incorporate advances in diagnosis, classification, treatment guidelines and clinical techniques, including the 2018 Classification and the EFP CPGs. Graduates evaluated their overall training positively, although satisfaction was limited for training in mucogingival and surgical procedures related to dental implants. Traditional educational methods, such as didactic lectures, are still commonly employed, but they are now often associated with more interactive methods such as case-based seminars and problem-based and simulation-based learning. The evaluation of competences/learning outcomes should employ multiple methods of assessment. CONCLUSION: An update of competences and learning outcomes of specialist training in periodontology is proposed, including knowledge and practical application of the 2018 Classification and CPGs. Harmonizing specialist training in periodontology is a critical issue at the European level.
RESUMO
DESIGN: A critical review on the use of antimicrobials in dentistry. AIM: To provide a general overview of the use of antimicrobials in dentistry. METHODS: The paper was divided into different topics, starting with an approach to understanding both commensal and pathogenic oral microbiota. Subsequently, emphasis was placed on the main categories of antibiotics used in dentistry (ß-lactams, tetracyclines, macrolides, lincosamides, nitroimidazoles and quinolones), and the basis for their prescription. Finally, the implications between systemic diseases and the use of orally-administered antibiotics are presented. RESULTS: The study suggests that an adequate medical history can minimize the risk of systemic adverse effects, unwanted drug interactions, and allergies related to the use of antibiotics. In this regard, when facing a potential history of allergy to a particular group of antibiotics, the prescription of a different group is mandatory. In most indications, ß-lactam antibiotics represent the first-choice in dentistry. Moreover, a short-term prescription of antibiotics when treating acute oral infections is recommended. The use should be extended for 2 to 3 days following the resolution of the infection, with an average duration of 6 days in order to prevent the development of antibiotic resistance. CONCLUSIONS: Oral infections should be managed with interventions aiming at the elimination/reduction of the associated pathogens. Furthermore, inadequate prescription of antibiotics can lead to potential risks to the patient such as allergy, adverse effects, and development of microbial resistance.
RESUMO
This comprehensive review aimed (1) to characterize the sub- and supragingival microbiome in patients with biofilm-induced gingivitis (including experimental gingivitis), (2) to assess its stability and evolution over time, and (3) to assess the impact of biofilm control measures on this stability. An electronic search of the MEDLINE®/PubMed® database until December 2023 was conducted. NCBI Taxonomy, eHOMD 16S rRNA Reference Sequence, and Tree Version 15.23 databases were used to standardize taxonomic nomenclature. Out of 89 papers initially retrieved, 14 studies were finally included: 11 using experimental gingivitis as a model and three randomized clinical trials evaluating the impact of biofilm control measures. Among them, five characterized the subgingival microbiome, nine the supragingival microbiome, and one both the sub- and supragingival microbiome. In addition, five studies evaluated the effect of toothpaste, and four studies evaluated the effect of mouth rinses. The diversity and structure of the microbiome differed significantly between patients with periodontal health and those with biofilm-induced gingivitis (including experimental gingivitis). Those differences were not reversed through conventional oral hygiene measures. Specific antiseptic agents, especially if delivered as mouth rinses, may have an impact on the supra- and subgingival microbiome in gingivitis.
RESUMO
BACKGROUND: Metformin treatment is a recommended first-line medication for patients with type 2 diabetes. Latino patients are subject to factors that may modify their level of diabetes care, including medication prescription. We evaluated the odds of and times to metformin prescription among non-Latino whites, English-preferring Latinos, and Spanish-preferring Latinos with diabetes. METHODS: We constructed a retrospective cohort of 154,368 adult patients from 835 community health centers (CHCs) across 20 states who were diagnosed with diabetes during the study. Patients were from non-Latino white, English-preferring Latino, and Spanish-preferring Latino ethnic/language groups. We modeled adjusted odds of metformin prescription and adjusted hazards (time-to-event) of metformin prescription after diabetes diagnosis and high hemoglobin A1c (HbA1c > 9) test results. RESULTS: English-preferring Latinos had similar odds of metformin prescription (Odds Ratio (OR) = 1.01 (95% CI = 0.93, 1.09)), slightly lower time to metformin prescription after diabetes diagnosis (Hazard Ratio (HR) = 1.06(95% CI = 1.04, 1.09)), and similar time to metformin prescription after a high HbA1c result (HR = 1.04 (0.99, 1.09)) compared to non-Latino whites. Spanish-preferring Latinos had higher odds of metformin prescription (OR) = 1.42 (95% CI = 1.33, 1.52), and less time to prescription after diabetes diagnosis (HR = 1.18 (1.15, 1.20)) and after a high HbA1c result (HR = 1.15 (1.11, 1.20)). CONCLUSIONS: Our analysis of metformin prescription patterns among non-Latino whites, English-preferring Latinos, and Spanish-preferring Latinos did not suggest a lower or slower tendency to prescribe metformin in Latino patients. Understanding disparities in diabetes diagnosis may require further investigation of medication adherence barriers, diet and exercise counseling, and multi-level influences on diabetes outcomes in Latino patients.

INTRODUCTION: The genus Bartonella includes species and subspecies of fastidious, facultative intracellular Gram-negative bacilli that infect a wide variety of mammalian reservoirs including cats and humans. In 2022, the Ecuadorian Ministry of Health reported an outbreak of cat scratch disease caused by B. henselae in the city of Guayaquil. Therefore, we aimed to characterize the presence of Bartonella spp. in domestic and stray cats from the area of Guayaquil where the outbreak happened in 2022. METHODS: Whole blood samples of 100 domestic and stray cats were collected. Riboflavin synthase (ribC) and 16S rRNA genes detection was performed by PCR using Bartonella spp. specific primers, followed by Sanger sequencing and phylogenetic analysis. RESULTS: 14 cats were positive for Bartonella spp. carriage. Phylogenetic analysis confirmed the presence of 12 cats infected with B. henselae and 2 cats with B. clarridgeiae. CONCLUSIONS: There is a high prevalence of Bartonella spp. carriage in cats in the city of Guayaquil within the area where a recent cat scratch disease outbreak happened. Considering the high presence of cats and other domestic and stray animals in the city of Guayaquil, a One Health approach for surveillance and prevention of zoonotic diseases like cat scratch disease is needed.

BACKGROUND: Burnout in primary care undermines worker well-being and patient care. Many factors contribute to burnout, including high workloads, emotional stress, and unsupportive supervisors. Formative evidence suggests that burnout might be reduced if clinic leaders hold quarterly and brief (â¼30 min) one-on-one check-ins with team members to acknowledge and address work-life stressors (e.g., schedules, workflow breakdowns, time off requests). This paper describes the intervention protocol for a randomized controlled trial (RCT) designed to evaluate the effectiveness and process of the check-ins in reducing burnout among primary care professionals. METHODS: Two-arm RCT conducted at 12 primary care clinics of a healthcare system in the Pacific Northwest. Six clinics received an adaptive design, semi-structured intervention, including predefined training modules with evidence-based tactics to reduce burnout through the check-ins, followed by clinic-specific feedback sessions prior to offering and conducting quarterly leader-employee check-ins. Six clinics were randomized as waitlist controls. Burnout was measured using the Maslach Burnout Inventory (MBI) at baseline and at the 12-month follow-up. Secondary outcomes include organizational constraints, psychological safety, and supervisor support. Multilevel modeling and qualitative methods were applied to evaluate the effects and process of the intervention. CONCLUSION: By focusing on modifiable work-life factors such as stressors and supervisor support, the check-ins intervention aims to reduce burnout rates among primary care professionals. Findings from this trial will shed light on the conditions upon which check-ins might reduce burnout. Results will also inform policies and interventions aimed at improving mental health and well-being in primary care settings. CLINICALTRIALS: gov: ID NCT05436548.

BACKGROUND: The second European Consensus Workshop on Education in Periodontology was commissioned, as a result of the changes in the discipline and the advances in educational methods/technology, to update the 2009 Consensus report of the first European Federation of Periodontology (EFP) Workshop on the same topic that was jointly authored by the Association for Dental Education in Europe. AIM: To identify and propose changes necessary in periodontal education at three levels, namely undergraduate, specialist and continuing professional development (CPD), with respect to learning outcomes, competencies and methods of learning/training and evaluation. METHODS: Four working groups (WGs) considered education in periodontology at the undergraduate, specialist and CPD levels, and education methods. Four commissioned position papers, one per WG, summarized the relevant information. Workshop participants gathered at an in-person consensus meeting to discuss the individual reviews, and this consensus report summarizes the conclusions. RESULTS: The learning outcomes for undergraduate and specialist education in periodontology have been updated, and a proposal for learning outcomes for CPD programmes was made. Learning/teaching/training and evaluation methods were proposed for each level of education, which included face-to-face, virtual and blended learning methods. CONCLUSION: Developments in oral/dental medicine and in contemporary educational technologies have been translated into updated learning outcomes and learning/teaching/ training/evaluation methods relevant to education in periodontology.
RESUMO
Carbohydrate reserves play a vital role in plant survival during periods of negative carbon balance. Under a carbon-limited scenario, we expect a trade-offs between carbon allocation to growth, reserves, and defense. A resulting hypothesis is that carbon allocation to reserves exhibits a coordinated variation with functional traits associated with the 'fast-slow' plant economics spectrum. We tested the relationship between non-structural carbohydrates (NSC) of tree organs and functional traits using 61 angiosperm tree species from temperate and tropical forests with phylogenetic hierarchical Bayesian models. Our results provide evidence that NSC concentrations in stems and branches are decoupled from plant functional traits. while those in roots are weakly coupled with plant functional traits. In contrast, we found that variation between NSC concentrations in leaves and the fast-slow trait spectrum was coordinated, as species with higher leaf NSC had trait values associated with resource conservative species, such as lower SLA, leaf N, and leaf P. We also detected a small effect of leaf habit on the variation of NSC concentrations in branches and roots. Efforts to predict the response of ecosystems to global change will need to integrate a suite of plant traits, such as NSC concentrations in woody organs, that are independent of the 'fast-slow' plant economics spectrum and that capture how species respond to a broad range of global change drivers.
RESUMO
Wastewater surveillance represents an alternative approach to regulating contamination and the early detection of infectious agents and outbreaks of diseases of public health importance. This study evaluated domestic wastewater effects on recreational waters in estuarine and seawater bodies in Guayas and Santa Elena provinces in Ecuador, South America. Fecal indicator bacteria (thermotolerant coliforms) served as key indicators for evaluation. Physical, chemical, and microbiological quality markers following the Ecuadorian environmental quality standard and the discharge of effluents to the water resource were analyzed. Samples were collected from 44 coastal sites and 2 oxidation lagoons during the dry and rainy seasons of 2020 and 2021, respectively. SARS-CoV-2 RNA was detected in samples with higher E. coli concentrations using reverse transcription quantitative PCR to detect the genes N and ORF1ab. All samples analyzed for SARS-CoV-2 showed Ct Ë 40 for at least one gene. Four samples showed at least 20 genome copies of gene N per reaction. These were at an artisanal fishing port, an estuarine area (Palmar), a recreational bay, and an oxidation lagoon. A moderate correlation was found between SARS-CoV-2 RNA, thermotolerant coliform and E. coli (p-value ≤ 0.0037), and a strong and positive correlation between thermotolerant coliform and E. coli. (p-value ≤ 0.00001), highlighting the utility of these established parameters as a proxy of the virus. Significant differences were found in the concentrations of thermotolerant coliforms between seasons (p-value = 0.016) and sites (p-value = 0.005). The highest levels of coliforms were found in the dry season (63000 MPN/100 mL) in Anconcito and during the rainy season (14000 MPN/100 mL) at Esterillo in Playas County. It is recommended that the decentralized autonomous governments of the surveyed provinces in Ecuador implement urgent corrective actions and establish medium-term mechanisms to minimize a potential contamination route. Additional parameters must be included in the monitoring, such as Enterococcus and intestinal parasites, due to their public health implications. In the oxidation lagoons, maintenance actions must be carried out, including the dissolution of sediments, an increase in water retention times, and in situ treatment of the sludge, to improve the system's performance.

Despite the understanding of the coronavirus disease-19 (COVID-19), the role of salivary extracellular vesicles (sEVs) in COVID-19 remains unclear. Exploring the proteomic cargo of sEVs could prove valuable for diagnostic and prognostic purposes in assessing COVID-19. The proteomic cargo of sEVs from COVID-19(+) subjects and their healthy close contacts (HCC) was explored. sEVs were isolated by ultracentrifugation from unstimulated saliva samples, and subsequently characterized through nanoparticle tracking, transmission electron microscopy, and Western blot analyses. The proteomic cargo of sEVs was processed by LC-MS/MS. sEVs were morphologically compatible with EVs, with the presence of Syntenin-1 and CD81 EV markers. The sEV pellet showed 1417 proteins: 1288 in COVID-19(+) cases and 1382 in HCC. In total, 124 proteins were differentially expressed in sEVs from COVID-19(+) subjects. "Coronavirus-disease response", "complement and coagulation cascades", and "PMN extracellular trap formation" were the most enriched KEGG pathways in COVID-19(+) cases. The most represented biological processes were "Hemoglobin and haptoglobin binding" and "oxygen carrier activity", and the best-denoted molecular functions were "regulated exocytosis and secretion" and "leucocyte and PMN mediated immunity". sEV proteomic cargo in COVID-19(+) suggests activity related to immune response processes, oxygen transport, and antioxidant mechanisms. In contrast, in HCC, sEV signature profiles are mainly associated with epithelial homeostasis.

BACKGROUND: Periodontitis is a chronic inflammatory non-communicable disease (NCD) characterised by the destruction of the tooth-supporting apparatus (periodontium), including alveolar bone, the presence of periodontal pockets, and bleeding on probing. OBJECTIVES: To outline, for family doctors, the implications of the association between periodontal and systemic diseases; to explore the role of family doctors in managing periodontitis as an ubiquitous non-communicable disease (NCD). METHODS: The consensus reports of previous focused collaborative workshops between WONCA Europe and the European Federation of Periodontology (using previously undertaken systematic reviews), and a specifically commissioned systematic review formed the technical papers to underpin discussions. Working groups prepared proposals independently, and the proposals were subsequently discussed and approved at plenary meetings. RESULTS: Periodontitis is independently associated with cardiovascular diseases, diabetes, chronic obstructive pulmonary disease, obstructive sleep apnoea, and COVID-19 complications. Treatment of periodontitis has been associated with improvements in systemic health outcomes. The article also presents evidence gaps. Oral health care professionals (OHPs) and family doctors should collaborate in managing these conditions, including implementing strategies for early case detection of periodontitis in primary medical care centres and of systemic NCDs in oral/dental care settings. There is a need to raise awareness of periodontal diseases, their consequences, and the associated risk factors amongst family doctors. CONCLUSION: Closer collaboration between OHPs and family doctors is important in the early case detection and management of NCDs like cardiovascular diseases, diabetes mellitus, and respiratory diseases. Strategies for early case detection/prevention of NCDs, including periodontitis, should be developed for family doctors, other health professionals (OHPs), and healthcare funders. Evidence-based information on the reported associations between periodontitis and other NCDs should be made available to family doctors, OHPs, healthcare funders, patients, and the general population.
Periodontitis is independently associated with cardiovascular diseases, diabetes, chronic obstructive pulmonary disease, obstructive sleep apnoea, and COVID-19.Periodontal treatment for optimal outcomes improves diabetes outcomes and surrogate measures of cardiovascular risk.Closer collaboration between oral health care professionals and family doctors is important in the early case detection and management of non-communicable diseases.Information on the reported associations should be made available to family doctors, oral health professionals, healthcare funders, patients, and the general population.

This study aimed to evaluate the impact of Candida albicans on subgingival biofilm formation on dental implant surfaces. Scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) were used to compare biofilm structure and microbial biomass in the presence and absence of the fungus after periods of 24, 48, and 72 h. Quantitative polymerase chain reaction (qPCR) was used to quantify the number of viable and total micro-organisms for each of the biofilm-forming strains. A general linear model was applied to compare CLSM and qPCR results between the control and test conditions. The biofilm developed with C. albicans at 72 h had a higher bacterial biomass and a significantly higher cell viability (p < 0.05). After both 48 and 72 h of incubation, in the presence of C. albicans, there was a significant increase in counts of Fusobacterium nucleatum and Porphyromonas gingivalis and in the cell viability of Streptococcus oralis, Aggregatibacter actinomycetemcomitans, F. nucleatum, and P. gingivalis. Using a dynamic in vitro multispecies biofilm model, C. albicans exacerbated the development of the biofilm grown on dental implant surfaces, significantly increasing the number and cell viability of periodontal bacteria.

OBJECTIVE: To determine whether electronic health record (EHR) documentation of certain early childhood risk factors for asthma, such as wheeze differ by race, ethnicity, and language group, and whether these children have different subsequent asthma prevalences. METHODS: We used EHR data from the Accelerating Data Value Across a National Community Health Center (ADVANCE) Clinical Research Network from children receiving care in US community health centers (n = 71,259 children) across 21 states to examine the presence of ICD-coded documentation of early childhood wheeze and its association with subsequent asthma diagnosis documentation in the EHR by race/ethnicity/language. RESULTS: ICD-coded wheeze was present in 2 to 3% of each race/ethnicity/language group. Among the total sample, 18.5% had asthma diagnosed after age 4. The adjusted prevalence of subsequent asthma diagnosis was greater in children with wheeze than those without. Odds of asthma diagnosis did not differ among children in all race/ethnicity/language groups with early childhood wheeze. Non-Latino Black children without wheeze had higher odds of asthma (OR = 1.19, 95% CI = 1.08-1.32) compared with non-Latino White children without wheeze. DISCUSSION: In US community health centers which serve medically underserved populations, EHR documentation of early childhood wheeze was uncommon and did not differ significantly among race/ethnicity/language groups. Differences in asthma diagnosis in Latinos may not stem from differences in early-life wheeze documentation. However, our findings suggest that there may be opportunities for improvement in early asthma symptom recognition for non-Latino Black children, especially in those without early childhood wheeze.

AIM: To evaluate the cross-sectional association between severe periodontitis and diabetes mellitus (DM), in a representative sample of Spanish population. MATERIALS AND METHODS: The di@bet.es epidemiological study is a population-based cohort study aimed to determine the prevalence and incidence of DM in the adult population of Spain. The at-risk sample at the final examination (2016-2017) included 1751 subjects who completed an oral health questionnaire. This questionnaire, together with demographic and risk factors, had been previously validated to build an algorithm to predict severe periodontitis in the Spanish population. Logistic regression models were used to evaluate the association between severe periodontitis and DM with adjustment for confounding factors. RESULTS: In total, 144 subjects developed DM, which yielded 8.2% cumulative incidence. Severe periodontitis was detected in 59.0%, 54.7% or 68.8% of the subjects depending on three different selected criteria at the 2016-2017 exam. All criteria used to define severe periodontitis were associated with DM in unadjusted analysis, but the magnitude of the association decreased after adjusting for significant confounders. The criteria '≥50% of teeth with clinical attachment loss ≥5 mm' presented an odds ratio of 4.9 (95% confidence interval: 2.2-10.7; p ≤ .001) for DM. CONCLUSIONS: Severe periodontitis is associated with DM in the Spanish population.

BACKGROUND AND OBJECTIVE: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030. METHODS: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries. An open questionnaire of 60 questions was validated and used following the Delphi methodology. RESULTS: Two hundred and twenty-five experts from Latin America answered the two rounds of the questionnaire. Moderate to strong consensus was reached on 45 questions (75%). The prediction was that the prevalence of gingivitis and periodontitis in stages I and II will be maintained, the importance of the link with systemic diseases will increase, and the impact of prevention and periodontal treatment will also increase, mainly in the private sector. There was a strong consensus that plastic and regenerative surgical procedures will increase, as well as the demand for training in the specialty of periodontology. CONCLUSIONS: The present study has provided relevant and useful information on predictions in periodontology/periodontics in Latin America, with important level of consensus among experts. It has been predicted that periodontitis will still be a highly prevalent disease, and its links with other medical conditions should demand more attention by health authorities to develop adequate prevention and management policies and strategies.

RESUMO
INTRODUCTION: The use of tissue adhesives has been proposed as an anastomosis reinforcement; however, their efficacy has not been evaluated in a contaminated environment. The objective of this study was to determine if the use of sutures reinforced with ethyl-2-cyanoacrylate for colonic anastomoses in the presence of fecal peritonitis, in a murine animal model, decreases the frequency of dehiscence. METHODS: Wistar rats were used. Fecal peritonitis was established until reaching 18 hours of evolution. Then, resection and anastomosis of the colon were performed with only polydioxanone (PDS) sutures in the control group and reinforcement with ethyl-2-cyanoacrylate in the experimental group. The dehiscence frequency and burst pressure were evaluated six days after the anastomosis was performed. RESULTS: We included 30 Wistar rats, all males, with a median age of five months and an average weight of 350.43 g. Anastomotic dehiscence was observed in 53.33% of the control group, in contrast with 13.33% of the experimental group (p = 0.020). There was no significant difference in burst pressure between the two groups. CONCLUSION: The use of ethyl-2-cyanoacrylate, in an experimental murine animal model, as reinforcement in colonic anastomoses in the presence of fecal peritonitis decreases the frequency of anastomotic dehiscence, although it does not increase resistance to burst pressure.
RESUMO
CaVγ2 (Stargazin or TARPγ2) is a protein expressed in various types of neurons whose function was initially associated with a decrease in the functional expression of voltage-gated presynaptic Ca2+ channels (CaV) and which is now known to promote the trafficking of the postsynaptic α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors (AMPAR) towards the cell membrane. Alterations in CaVγ2 expression has been associated with several neurological disorders, such as absence epilepsy. However, its regulation at the transcriptional level has not been intensively addressed. It has been reported that the promoter of the Cacng2 gene, encoding the rat CaVγ2, is bidirectional and regulates the transcription of a long non-coding RNA (lncRNA) in the antisense direction. Here, we investigate the proximal promoter region of the human CACNG2 gene in the antisense direction and show that this region includes two functional cAMP response elements that regulate the expression of a lncRNA called CACNG2-DT. The activity of these sites is significantly enhanced by forskolin, an adenylate cyclase activator, and inhibited by H89, a protein kinase A (PKA) antagonist. Therefore, this regulatory mechanism implies the activation of G protein-coupled receptors and downstream phosphorylation. Interestingly, we also found that the expression of CACNG2-DT may increase the levels of the CaVγ2 subunit. Together, these data provide novel information on the organization of the human CACNG2-DT gene promoter, describe modulatory domains and mechanisms that can mediate various regulatory inputs, and provide initial information on the molecular mechanisms that regulate the functional expression of the CaVγ2 protein.
RESUMO
Background: Acute intracerebral hemorrhage affects annually more than 1 million people worldwide. Chronic systemic arterial hypertension is the most important modifiable risk factor for spontaneous intracerebral hemorrhage. Objective: To determine the relationship between the decrease in systolic blood pressure (SBP) in patients with intracranial hemorrhage and their short-term functional prognosis. Material and methods: Observational, longitudinal, prospective study in patients with intraparenchymal hemorrhage secondary to hypertensive dyscontrol, older than 18 years, of both sexes. Blood pressure was recorded at admission, every hour during the first 6 hours and every two hours from 8 to 24 hours after admission. Functionality was assessed using the modified Rankin scale at admission, at 6 and 24 hours after admission. Results: 58 patients were included, in whom the reduction of systolic blood pressure at admission was 17.04% and at 24 hours was 31.3 mm Hg; the mean systolic blood pressure was 183.62 mm Hg as opposed to 152.3 mm Hg at discharge (p < 0.001). Conclusions: In the first 6 hours, reduction in ASR is significantly associated with hospital outcome in patients with intracranial hemorrhage. A linear association was observed with improvement and favorable functional prognosis as measured by the modified Rankin scale.

La hipertensión arterial sistémica crónica es el factor de riesgo modificable más importante para la hemorragia intracerebral espontánea. Objetivo: determinar la relación entre la disminución de la presión arterial sistólica (TAS) en pacientes con hemorragia intracraneal y su pronóstico funcional a corto plazo. Métodos: estudio observacional, longitudinal, prospectivo, en pacientes con hemorragia intraparenquimatosa secundaria a descontrol hipertensivo, mayores de 18 años, de ambos sexos. Se realizaron registros de presión arterial al ingreso, cada hora durante las primeras seis horas y cada dos horas desde las ocho a las 24 horas posterior al ingreso. Se evaluó funcionalidad mediante escala de Rankin modificada al ingreso, a las seis y a las 24 horas después del ingreso. Resultados: se incluyeron 58 pacientes, en quienes la reducción de la TAS al ingreso fue de 17.04% y a las 24 horas fue de 31.3 mm Hg de la presión arterial sistólica; la media de la TAS fue de 183.62 mm Hg a diferencia de la registrada al egreso, que fue de 152.3 mm Hg (p < 0.001). Conclusiones: en las primeras seis horas, la reducción de la TAS está significativamente asociada con el resultado hospitalario en pacientes con hemorragia intracraneal. Se observó una asociación lineal con la mejoría y un pronóstico funcional favorable, medido por la escala de Rankin modificada.
