Caracterización Clínica y Desenlaces Hospitalarios en Adultos Con Meningitis en un Hospital de Alta Complejidad en Colombia (2019–2021). Clinical Characteristics And In-Hospital Outcomes In Adults With Meningitis In A High-Complexity Hospital In Colombia (2019–2021)

Introduction: Bacterial meningitis in adults is a time-dependent medical emergency due to its rapid progression, risk of septic shock, and severe neurological complications. The objective was to characterize the clinical profile, cerebrospinal fluid (CSF) cytochemical findings, and in-hospital outcomes in adult patients with a clinical diagnosis of meningitis.

Methods: A single-center, retrospective observational cohort study was conducted at a high-complexity hospital in Tunja, Colombia, a regional referral center. Patients with a clinical diagnosis of meningitis who underwent diagnostic lumbar puncture between 2019 and 2021 were included.

Results: Thirty-two patients were included, with a median age of 52 years and a male predominance. The most frequent symptoms were headache and fever; 53.1% presented with altered mental status at admission. CSF analysis showed pleocytosis with predominance of polymorphonuclear cells, low glucose levels, and elevated protein concentrations. In-hospital mortality was 21.9%, 25.0% of patients required admission to the intensive care unit, and 84.4% developed at least one complication.

Conclusions: Patients exhibited a clinical and cytochemical profile consistent with bacterial etiology and a high frequency of adverse outcomes (mortality ~22% and 84% complications). These findings highlight the severity of the condition and the need for timely diagnosis and treatment.

IMPACT Score as a Predictor of Mortality in Patients with Severe Traumatic Brain Injury in The Intensive Care Unit. Puntaje IMPACT como Predictor de Mortalidad en Pacientes con Traumatismo Craneoencefálico Severo en la Unidad de Cuidados Intensivos

Objective: To assess whether the IMPACT score predicts mortality in patients with traumatic brain injury (TBI).

Design: Cohort study.

Setting: A total of 260 patients with moderate and severe TBI were enrolled from the Intensive Care Unit (ICU) of Hospital Regional Docente de Trujillo, a trauma referral hospital in northern Peru. The data collection period spanned from 2018 to 2023.

Patients: Patients with moderate and severe TBI admitted to the ICU.

Interventions: Patients with TBI in whom the predictive performance of the IMP ACT score for mortality was assessed.

Main Outcome Measure: In-hospital mortality.

Results: A total of 260 patients with moderate and severe TBI were included. When evaluating the IMPACT score and its models (core, extended, and laboratory), we found adequate predictive values expressed by their respective ROC AUCs (0.74, 0.83, and 0.84). Additionally, upon constructing a predictive model utilizing the IMPACT score laboratory model, an increased risk of mortality was observed (adjusted RR 1.21; 95% CI 1.12–1.31). Furthermore, the variables: mechanism of TBI (adjusted RR 5.6; 95% CI 3.03–10.85), Glasgow Coma Scale (GCS) (adjusted RR 1.35; 95% CI 1.15–1.58), and use of vasopressors (adjusted RR 2.2; 95% CI 1.14–4.42) behaved as independent predictors of in-hospital mortality.

Mortalidad y pronóstico funcional en pacientes con infarto cerebral en una ciudad a gran altitud (Cusco, 3300m) durante la pandemia por COVID-19. Mortality and functional prognosis in patients with ischemic stroke residing in a high-altitude city (Cusco, 3300 m) during the covid-19 pandemic.

Introduction: Information on stroke mortality in people residing at high altitudes is controversial, and during the coronavirus disease 2019 (COVID-19) pandemic, there was a decrease in in-person care. Our objective is to evaluate mortality and functional prognosis after 3 months in stroke patients residing at high altitude during the COVID-19 pandemic. Methods: An analytical longitudinal study was conducted from January 2020 to January 2022 in a hospital in Cusco (3300 m above sea level), including adult patients diagnosed with stroke but without COVID-19 diagnosis, who were followed up for 90 days, evaluating mortality and functional disability (modified Rankin scale ≥ 3). Clinical and laboratory risk factors were evaluated, obtaining crude and adjusted hazard ratios (HR) through Cox regression models with 95% confidence intervals (CI95%). Results: One hundred twenty-three stroke patients were evaluated. After 90 days of follow-up, 28 patients (22.7%) died and 80 patients (65.0%) were diagnosed with functional disability. In models adjusted for gender, age, Alberta stroke program early CT (ASPECTS) score, and hypertension background, the only variable with increased risk was National Institutes of Health Stroke Scale (NIHSS) score at admission, both for mortality (HR 1.14, CI95% 1.09–1.20) and functional disability (HR 1.07, CI95% 1.04–1.11). Conclusions: Regarding stroke patients cared for in a high-altitude city during the COVID-19 pandemic, NIHSS score at admission is the most important risk factor for determining the 90-day mortality or functional disability, with a risk increase of approximately 10% for both outcomes for each additional point on the scale.

Complicaciones intrahospitalarias del evento cerebrovascular isquémico de novo en centros hospitalarios de segundo nivel de atención. Inpatient complications of de novo ischemic stroke in second level care hospitals.

The ischemic stroke (IS) is one of the leading causes of mortality worldwide. approximately 90% of patients manifest complications that have been progressively increasing since the last decades. The objective of the study is to determine the inpatient complications of IS in second level hospitals during the period 2020-2022.

Methodology: A retrospective study was carried out in two second level hospitals in Guayaquil. Patients with age ≥ 40 years with de novo ischemic cerebrovascular disease were included. The Oxfordshire Community Stroke Project (OCSP) classification was used to categorize patients according to the affected circulation, with the neurologist being the professional responsible for carrying out said categorization. Descriptive statistics were applied to determine the most frequent neurological complications (NC) and extraneurological (ENC), using frequencies and percentages.

Results: In 320 patients with IS, 64% were men with a mean age of 70 years. In-hospital complications occurred in 72.8% of the patients. The average incidence of NC in the study population was 48.1% while ENC was 55.6%.

Conclusion: In-hospital complications of IS are frequent and their incidence varies depending on the affected circulation.

Hipernatremia como factor pronóstico de mortalidad en trauma encefalocraneano severo. Hypernatremia as a prognostic factor of mortality in patients with severe traumatic brain injury

Background: A severe traumatic brain injury is a frequent pathology, it implies a non-negligible morbidity and mortality. Hypernatremia could be considered a factor associated with poor prognosis in order to optimize treatment in the group of high-risk patients. We aim to determine if hypernatremia is a prognostic factor of mortality in patients with severe traumatic brain injury in a public hospital which is a local reference center in trauma.

Material and Methods: We performed a non-probabilistic sampling of adult patients of both sexes with severe traumatic brain injury from the Intensive Care Unit of the Hospital Regional Docente de Trujillo, Perú during the 2015–2018 period.

Results: Mortality in the group with and without hypernatremia was 38% and 6% respectively (p=0.001). The difference in natremia mean values between the group with and without mortality was 21,86 (95% CI 18.2-25.5) (p=0.000). In the multivariate analysis, we found hypernatremia with adjusted OR of 16.73 (95% CI 1.96-142.82) (p=0.01). The ROC curve showed adequate performance to predict mortality, with an AUC 0.878 (95% CI 0.77-0.97) (p=0.00).

Conclusion: Hypernatremia is a prognostic factor of mortality in patients with severe traumatic brain injury.

Evaluación de la Utilidad de las Escalas Pronósticas del Status Epiléptico Convulsivo en el Status Epiléptico no Convulsivo. Usefulness Of Status Convulsive Score In Prognosis Of Non-Convulsive Status Epilepticus

Introduction: The Non-Convulsive Status Epilepticus (NCSE) is a rare clinical entity. As of today, a predictive mortality scale has not been developed. Moreover, the risk factors that contribute to the prognosis have not been clearly defined. The aim of this study was to evaluate the usefulness of the prognostic scores for status epilepticus (SE): the epileptic status severity score (STESS), the modified RANKIN scale STESS (mRSTESS) and the epileptic status mortality score based on epidemiology (EMSE-EACEG) applied in patients diagnosed with NCSE.

Results: The sample analyzed for this study consisted of 66 patients with an average age of 59 years (SD 18.5).

The STESS and mRSTESS were significantly associated with higher odds for poor prognosis at the time of discharge in patients with NCSE (p<0.05 and p<0.05, respectively). However, none of the three was associated with mortality.

Conclusion: Considering that the scores used to predict prognosis in patients with SE have not shown equal diagnostic accuracy in the NCSE, we believe that a validated predictive scale of morbidity and mortality would be of great help for these patients.

Meningitis Criptocócica. Diferentes Contextos Clínicos y Complicaciones. Serie de 7 Casos. Cryptococal Meningitis. Different Clinical Context And Complications. Seven Cases.

Introduction. Cryptococcal meningitis (CM) is a serious infection of the Central Nervous System. The diagnosis and treatment of these patients is often complex, due to the severity of the clinical manifestations and their complications. The aim of this study is to describe the different clinical contexts, the neuroradiological characteristics and the complications of patients with CM.

Patients. We performed a retrospective review of clinical and radiological factors of 7 patient’s diagnosis and treated with CM during the period October 2016 and September 2017, at the Eugenio Espejo Hospital.

Results. Male sex was predominant (6/7), with an average age of 31.6 years (Range 19-44). The average time for the diagnosis was 8.1 weeks. Immunosuppression causes were evidenced in 5 patients, two HIV positive, one case with Acute Lymphoblastic Leukemia, CD4 idiopathic lymphopenia and Primary Intestinal Linfagectasia respectively. Three patients developed complications as disseminated cryptococcosis, visual acuity and hearing loss, mortality rate reach 26.8% of patients. Hypoglycorrhachia was a relevant feature with average 12.7mmg / dl. In MRI, the most common lesion was dilatation of Virchow Robins spaces (5/7), followed by ischemic lesions.

Conclusions. CM is characterized for high morbidity and mortality, initial symptoms may be nonspecific and delays the diagnosis as well as initiation of antifungal agents. Several predisposing immunosuppressive conditions can be found and sometimes a diagnostic challenge.

Estatus Epiléptico. Factores Asociados a Una Evolución Desfavorable en un Centro Terciario. Status Epilepticus. Prognostic Variables For An Unfavorable Outcome In A Tertiary Center Of Care.

Introduction. Status Epilepticus (SE) is a frequent neurologic emergency. Little research has been done in South America to evaluate the prognostic variables of mortality and disability in patients with SE. Objective. To determine the variables associated to an unfavorable outcome at hospital discharge in the patients who were treated for SE. Methods. A retrospective study was performed during the period of January 2016–June 2017. A total of 26 patients were diagnosed of SE and its different variants. The effects of clinical, radiological, and electroencephalographic features on hospital outcome according Rankin scale were evaluated  Results. Twelve (46.2%) patients had an unfavorable outcome at hospital discharge, while the mortality rate reached 23.1%. There was a predominance of males with a 76.9% of all the patients. The independent variables associated with an unfavorable outcome were the number of comorbidities (p=0.01, OR: 4.27-95%CI1.33-13.6), structural lesions on the Magnetic Resonance Image (MRI) (p=0.04, OR: 3.92-95%CI1.05-14.61) and refractory SE (p=0.01, OR: 12.52-95%CI1.85-84.44). There was also a trend for age (p=0.07 OR: 1.03-95%CI0.99-1.07). While an initial good clinical condition, according to the Glasgow Scale represent a protective factor (p=0.00 OR: 0.49-IC95% 0.29-0.84) of an unfavorable outcome. Conclusions. The unfavorable outcome was marginally associated with patient age, clinical status at the onset of SE according to the Glasgow Coma Scale, as well as brain lesions on brain MRI. Refractory SE and more than 4 comorbidities are predictors of an unfavorable outcome at hospital discharge.

Mortalidad por enfermedades cerebrovasculares en Ecuador 2001- 2015: Estudio de tendencias, aplicación del modelo de regresión joinpoint. Mortality due to cerebrovascular diseases in Ecuador 2001- 2015: a trend study, application of the joinpoint regression model.

Objective. To analyze the mortality trend for cerebrovascular diseases in Ecuador and to identify the presence of changes in the temporal trend using the joinpoint regression model.

Materials and Methods. A mixed ecological study was carried out. Standardized mortality rates for the last 15 years (2001 to 2015) in Ecuador were calculated and stratified by age, sex, and provinces. A joinpoint regression analysis was used for analysis of trends.

Results. From 2001 to 2015, there were 48,621 deaths from cerebrovascular diseases in Ecuador. In the joinpoint regression analysis, age-adjusted rates in men declined from 71.4 to 59.5 deaths per 100,000 population, with an annual decline of 1.51% (p <0.05) in females from 61.2 to 55.5 deaths per 100,000 population, with an annual decrease of 1.11% (p <0.05). In the analysis by provinces, Sucumbíos presented a growing trend of 3.17% per year (p <0.05).

Conclusions. Mortality from cerebrovascular disease has declined in Ecuador in the last 15 years. The downward trend was observed in almost all age demographics.

Tabaquismo y su Asociación con Mortalidad Intrahospitalaria en Pacientes con Ictus Hemorrágico. Cigarette Smoking And Its Association With In-Hospital Mortality In Hemorrhagic Stroke Patients.

Background: Smoking is a well-known reversible risk factor associated with acute ischemic stroke (AIS), however, some data showed that in-hospital mortality rates among smoker’s patients with hemorrhagic stroke is lower when compared with non-smokers patients. The objective of this analysis was to assess in-hospital patient mortality rate between smokers and non-smokers patients with confirmed diagnosis of hemorrhagic stroke. Methods and Results: We analyzed all the data from patients diagnosed with hemorrhagic stroke that were registered in the Florida Stroke database from 2008-2012. Among the 21,013 patients diagnosed with hemorrhagic stroke, 10.9% of patients were smokers. A Multivariable model was used to estimate the adjusted odds ratio of in-hospital mortality rate in smokers versus non-smokers.  Smoking was associated with lower in-hospital mortality in hemorrhagic patients. (UOR= 0.71 vs. AOR= 0.75). Other risk factors like hypertension, BMI>40 and hyperlipidemia, remained significantly associated after modeling, and some others like gender, race, health insurance coverage, and diabetes became insignificant. The difference between unadjusted and adjusted odds ratios for smoking (0.71 versus 0.75) indicates no presence of substantial confounding by age and other control variables. Conclusions: Among patients hospitalized for hemorrhagic stroke, smoking is a risk factor for early age of onset, even among those with few vascular risk factors. The persistent association with lower in-hospital mortality after adjusted analyses probably represents other unmeasured confounding, although a biological effect of smoking cannot be excluded. Further clinical and prospective population-based studies are needed to explore variables that contribute to outcomes in these patients.
