RESUMO

OBJECTIVE: Various systemic inflammation response indexes (SIRI) have repeatedly been described as prognostic factors in ovarian cancer. They have not been validated in prospective trials and published results are sometimes contradictory. We aimed to explore their role in a cohort of patients diagnosed with stage III and IV ovarian cancer treated at our institution. METHODS: We retrospectively examined the prognostic influence of the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the monocyte-to-lymphocyte ratio (MLR), the red cell distribution width (RDW), and the mean platelet volume (MPV). RESULTS: A total of 77 patients were analyzed. NLR > 2.243 at diagnosis, NLR before primary surgery, MLR at diagnosis, PLR > 289.1 at diagnosis, and PLR at diagnosis were significant in univariate Cox regression for progression-free survival, but none of them retained their significance in the multivariate Cox regression analysis. For overall survival, NLR > = 2.53 at diagnosis, MLR > = 0.245 at diagnosis, and PLR > = 198.3 at diagnosis resulted significant in univariate COX regression; only PLR > = 198.3 at diagnosis retained its significance in the multivariate analysis. CONCLUSION: In our cohort, PLR > = 198.3 was an independent prognostic factor for worse OS. The definitive role of SIRI in ovarian cancer has not yet been established. If their value as prognostic factors could finally be established, they would become a simple and economical method to predict prognosis in patients with advanced ovarian cancer. Therefore, it is time to conduct prospective, multicenter studies with larger samples to definitively establish its role in ovarian cancer, if any.

RESUMO

OBJECTIVE: This study aimed to evaluate the value of platelet activation markers in predicting preeclampsia and its severity. Preeclampsia is a serious pregnancy complication that affects 3-5% of pregnancies and can lead to significant morbidity and mortality for both the mother and the fetus. METHODS: The study included 99 patients diagnosed with preeclampsia and 60 healthy pregnant women as a control group. Platelet activation markers such as mean platelet volume (MPV), platelet distribution width (PDW), platelet count, and plateletcrit were evaluated along with other clinical parameters. RESULTS: The results of the study showed that platelet activation markers, particularly PDW and MPV, are valuable in the diagnosis and follow-up of preeclampsia. However, they are not sufficient to predict the severity of the disease. CONCLUSION: The study suggests that platelet activation markers could aid in predicting, diagnosing, and managing preeclampsia. However, further research is needed to determine the role of these markers in predicting the severity of the disease. The findings of this study could contribute to the development of more effective strategies for the prevention and management of preeclampsia, which could ultimately improve maternal and fetal outcomes.

OBJETIVO: El estudio tuvo como objetivo determinar el valor de los marcadores de activación plaquetaria en la predicción de la preeclampsia y su gravedad. MÉTODO: Se incluyeron 99 pacientes diagnosticadas con preeclampsia, incluyendo 36 casos graves, y un grupo control de 60 mujeres embarazadas sanas. Se evaluaron diversas variables, como el volumen plaquetario medio, el recuento de plaquetas, el hematocrito plaquetario y la amplitud de distribución plaquetaria. RESULTADOS: Los resultados mostraron que el volumen plaquetario medio y la amplitud de distribución plaquetaria son parámetros valiosos en el diagnóstico y seguimiento de la preeclampsia, aunque no son suficientes para predecir su gravedad. El análisis estadístico reveló que la edad, el volumen plaquetario medio, la amplitud de distribución plaquetaria, la semana de gestación y los puntajes de Apgar al primer y quinto minuto fueron significativamente diferentes en el grupo de preeclampsia en comparación con el grupo control. CONCLUSIONES: En conclusión, estos resultados sugieren que los marcadores de activación plaquetaria pueden ser útiles para el diagnóstico y seguimiento de la preeclampsia, y que el volumen plaquetario medio y la amplitud de distribución plaquetaria, por ser parámetros económicos y accesibles, podrían ayudar a predecir, diagnosticar y manejar esta complicación durante el embarazo.

RESUMO

ABSTRACT Objective: To examine the neutrophil-lymphocyte ratio, red cell distribution width and mean platelet volume in patients with febrile seizure and to determine their role in febrile seizure classification. Methods: This was a retrospective hospital-based study conducted among patients aged 5 to 72 months admitted with febrile seizure. Children who had febrile seizures due to upper respiratory tract infection were included in the study. The children were divided into two groups: simple febrile seizures and complex febrile seizures. Patients with a history of febrile status epilepticus, previous convulsions, use of antiepileptic or other chronic drugs, foci of infection other than the upper respiratory tract infection, abnormal biochemical parameters, and chronic mental or physical disease were excluded from the study. Clinical and laboratory findings of the patients were obtained from digital medical records. Results: The records of 112 febrile seizure patients were reviewed, and 89 were grouped as simple and 23 as complex febrile seizures. Although there was no statistically significant difference between the two groups in terms of the mean red cell distribution width values (p=0.703), neutrophil-lymphocyte ratio and mean platelet volume were significantly higher in patients with complex febrile seizures (p=0.034, p=0.037; respectively). Conclusions: This study showed that neutrophil-lymphocyte ratio and mean platelet volume could be practical and inexpensive clinical markers for febrile seizure classification. A similar result could not be reached for red cell distribution width in this study. These findings should be supported by multicenter studies with large samples.

RESUMO Objetivo: Examinar a relação linfócitos-neutrófilos, amplitude de distribuição de hemácias e volume médio de plaquetas em pacientes com convulsão febril, e determinar seu papel na classificação de convulsão febril. Métodos: Este foi um estudo retrospectivo de base hospitalar realizado com pacientes de 5 a 72 meses admitidos com convulsão febril. Crianças que tiveram convulsões febris em razão de infecção do trato respiratório superior foram incluídas no estudo. As crianças foram divididas em dois grupos: convulsões febris simples e complexas. Pacientes com história de Status epiléptico febril, convulsões prévias, uso de drogas antiepilépticas ou outras drogas crônicas, com focos de infecção que não a do trato respiratório superior, parâmetros bioquímicos anormais e doenças crônicas mentais ou físicas foram excluídos do estudo. Os achados clínicos e laboratoriais dos pacientes foram obtidos a partir dos prontuários médicos digitais. Resultados: Registros de 112 pacientes com convulsão febril foram revisados: 89 com convulsões febris simples e 23 com complexas. Embora não tenha havido diferença estatisticamente significativa entre os dois grupos em termos de valor médio de amplitude de distribuição de hemácias (p=0,703), a relação linfócitos-neutrófilos e o volume médio de plaquetas foram significativamente mais elevados em pacientes com convulsões febris simples (p=0,034, p=0,037; respectivamente). Conclusões: Este estudo mostrou que a relação linfócitos-neutrófilos e o volume médio de plaquetas podem ser marcadores clínicos práticos e de baixo custo para a classificação de convulsão febril. Um resultado semelhante não pôde ser alcançado para a amplitude de distribuição de hemácias neste estudo. Esses achados devem ser apoiados por estudos multicêntricos com grandes amostras.

RESUMO

INTRODUCTION AND AIMS: We aimed to investigate changes in initial platelet indices in patients arriving at the emergency department with acute cholecystitis. MATERIAL AND METHODS: A retrospective case-control study was conducted at a tertiary care teaching hospital. Demographics, comorbidities, laboratory data, length of hospital stay, and mortality data for the acute cholecystitis group were retrospectively obtained from the hospital digital database. Platelet count, mean platelet volume, plateletcrit, platelet distribution width, and platelet mass index were collected. RESULTS: A total of 553 patients with acute cholecystitis were the study cases, and 541 hospital employees were the study controls. According to the results of the multivariate analysis of the platelet indices studied, only mean platelet volume and platelet distribution width showed significant differences between the two groups (adjusted odds ratio: 2, 95% confidence interval: 1.4-2.7, p < 0.001 and adjusted odds ratio: 5.88, 95% confidence interval: 2.44-14.4, p < 0.001, respectively). The multivariate regression model created had an area under the curve of 0.969 in the prediction of acute cholecystitis (accuracy: 0.917, sensitivity: 89%, and specificity: 94.5%). CONCLUSION: The study results indicate that the initial mean platelet volume and platelet distribution width were independent predictors of acute cholecystitis.

RESUMO

Introduction: Mean platelet volume (MPV), platelet count, and neutrophil/lymphocyte ratio (NLR) have been proposed to be biomarkers of the chronic inflammatory process in schizophrenia and indicative of increased cardiovascular risk. Objective: To describe MPV, total platelet count (PLT), and NLR between healthy controls and patients with schizophrenia to determine the correlation between these parameters and the duration of untreated psychosis (DUP). Methods: In a retrospective cross-sectional study, we included 175 patients with schizophrenia who had never received psychiatric treatment, and who had undergone blood biometry and blood chemistry within 24 h of admission. Laboratory studies were determined by the impedance method on Coulter ac-T 5 diff hematological equipment. Results: Mean platelet volume levels in patients with schizophrenia were higher than in healthy controls but not statistically significant. The receiver operating characteristic curve for this parameter shows that the optimal cutoff point of agreement was 8.95 fL, with sensitivity and specificity for schizophrenia of 52% and 67%, respectively, and the area under the curve (AUC) was 0.580 (p = 0.079). DUP had no significant correlation with the blood parameters analyzed. Conclusion: The results partially support the hypothesis that MPV, platelet count, and NLR is related to schizophrenia, and further research is needed to establish whether there is an underlying chronic inflammatory process.

RESUMO

BACKGROUND: Papillary thyroid cancer is the most common endocrine neoplasia. There are prognostic factors that establish risk of recurrence and mortality; however, patients considered low risk may have a less favorable evolution and hence the importance of finding new markers. OBJECTIVE: To assess whether the mean platelet volume (MPV) and the platelet-lymphocyte index (PLI) show a relationship with the clinical staging in papillary thyroid cancer. METHOD: Retrospective, observational and analytical study. Preoperative MPV and PLI were recorded, its relationship with TNM and MACIS systems was sought, as well as locally advanced invasion and tumor focality. RESULTS: 107 cases treated from November 2017 to February 2020. No statistically significant difference was observed in these two preoperative parameters with advanced and initial stages, risk groups or tumor focality. The statistical analysis used was one-way ANOVA with SPSS 25, a 95% confidence interval and p < 0.05. CONCLUSIONS: Despite the logical reasoning of tumor pathophysiology, our study did not find a relationship between papillary thyroid carcinoma with MPV and PLI, and should be complemented with more extensive studies.

ANTECEDENTES: El cáncer papilar de tiroides es la neoplasia endocrina más frecuente. Existen factores pronósticos que establecen el riesgo de recurrencia y mortalidad; sin embargo, los pacientes considerados de bajo riesgo pueden llegar a presentar una evolución menos favorable, y de ahí la importancia de encontrar nuevos marcadores. OBJETIVO: Evaluar si el volumen plaquetario medio (VPM) y el índice plaquetas-linfocitos (IPL) presentan una relación con la etapificación clínica en el cáncer papilar de tiroides. MÉTODO: Estudio retrospectivo, observacional y analítico. Se registraron el VPM y el IPL preoperatorios, y se buscó su relación con los sistemas TNM y MACIS, así como con la invasión localmente avanzada y la focalidad del tumor. RESULTADOS: Se trataron 107 casos de noviembre de 2017 a febrero de 2020. No se observó diferencia estadísticamente significativa en estos dos parámetros preoperatorios o en estadios avanzados e iniciales, grupos de riesgo ni focalidad del tumor. El análisis estadístico utilizado fue ANOVA de una vía, con SPSS 25, con intervalo de confianza del 95% y p < 0.05. CONCLUSIONES: Pese al razonamiento lógico de la fisiopatología tumoral, en nuestro estudio no se encontró relación entre el carcinoma papilar de tiroides, el VPM y el IPL, y debiera complementarse con estudios más extensos.

RESUMO

SUMMARY OBJECTIVE: This study aimed at investigating whether there is a relationship between 7- or 30-day mortality and mean platelet volume, platelet distribution width, platelet count-to-total lymphocyte count ratio, or red cell distribution width in patients with traumatic brain injury. METHODS: We retrospectively analyzed intensive care unit patients with traumatic brain injury. We recorded patients' ages; genders; diagnoses; Glasgow Coma Scale scores; length of intensive care unit stay (in days); mean platelet volume, platelet distribution width, platelet count-to-total lymphocyte count ratio, and red cell distribution width values upon hospital admission; and health on the 7th and 30th days of their stays. RESULTS: We analyzed data from 110 patients. Of these, 84 (76.4%) were male and 26 (23.6%) were female. On the 7- and 30-day mortality evaluations, compared to the living patients, the deceased patients had a significantly higher median age and a significantly lower median Glasgow Coma Scale. Thus, increased age and lower Glasgow Coma Scale scores were associated with increased 7- and 30-day mortality rates. mean platelet volume and platelet distribution width values were similar in living and deceased patients. platelet count-to-total lymphocyte count ratio values were lower in deceased patients, but this difference was not statistically significant. Within 30 days after traumatic brain injury, deceased patients' red cell distribution width values were significantly elevated in deceased patients compared to those of living patients. CONCLUSION: Mean platelet volume, platelet distribution width, and platelet count-to-total lymphocyte count ratio values were not associated with 7- and 30-day mortality, whereas only elevated red cell distribution width was associated with 30-day mortality.

RESUMO

OBJECTIVES: A low Neutrophil Lymphocyte Ratio (NLR) has been shown to be associated with good prognosis in Bell's Palsy (BP). However, the effect of chronic diseases that may affect the NLR, including Diabetes Mellitus (DM), has not been clarified in this context. This study aimed to evaluate the relationship between NLR and Mean Platelet Volume (MPV) in BP according to whether it is accompanied by DM, and their relationship with prognosis. METHODS: A prospective observational study was conducted from May 2014 to May 2020 in a tertiary referral center, of all 79 consecutive participants diagnosed with BP in department of otolaryngology and 110 consecutive healthy participants admitted to the check-up unit. Patients diagnosed with BP were divided into two groups according to whether they were diagnosed with DM: diabetic BP patients (DM-BP, n = 33) and non-diabetic BP patients without any chronic disease (nonDM-BP, n = 46). Neutrophil (NEUT) and Lymphocyte (LYM) counts, and Mean Platelet Volume (MPV) were assessed from peripheral blood samples, and the NLR was calculated. Prognosis was evaluated using the House-Brackmann Score (HBS) six months after diagnosis. RESULTS: The mean NLR was 2.85 ±â€¯1.85 in BP patients and 1.69 ±â€¯0.65 in the control group. The mean NLR was significantly higher in BP patients than healthy controls (p < 0.001). The mean NLR was 2.58 ±â€¯1.83 in the nonDM-BP group, 3.23 ±â€¯1.83 in the DM-BP group, and 1.69 ±â€¯0.65 in the control group. The NLR was significantly higher in the nonDM-BP and DM-BP groups than in the control group (p < 0.05). The recovery was 90% according to the HBS. The optimal cut-off value was 2.41 (p = 0.5). CONCLUSION: The NLR was increased in both diabetic and non-diabetic BP and had similar prognostic value in predicting the HBS before treatment in diabetic and non-diabetic patients with BP. MPV wasn't significantly different in diabetic and non-diabetic BP patients compared with the normal population.

RESUMO

Background: The COVID-19 disease has represented one of the most important threats to health. The most severe form is acute respiratory distress syndrome (ARDS). The inflammatory response can cause hematologic changes. Objective: To determine the association between the Neutrophil/lymphocyte ratio (NLR) and the mean platelet volume (MPV) associated with mortality in critically ill patients with COVID-19 and ARDS. Material and methods: A retrospective study was carried out in an intensive care unit (ICU) in a public hospital, with patients in critical condition due to COVID-19 and on mechanical ventilation. The clinical characteristics of admission and severity of the disease were recorded. The end point was the ICU discharge condition. Results: 162 subjects were gathered, 103 were men, with a mean age of 54.54 ± 13.53 years. 66.7% died in the ICU. The NLR had an area under the curve (aROC) of 0.62, with a cut-off point for mortality of > 7.04, sensitivity of 94.4%, specificity of 29.63%. The VPM had an aROC of 0.65 with a cut-off point > 9.5, sensitivity of 30.84%, and specificity of 92.59%; finally, the APACHE II had an aROC of 0.67 with a cut-off point > 14, sensitivity of 51.4% and specificity of 80%. The NLR presented an odds ratio (OR) of 5.02, the VPM 2.06 and the APACHE II score 1.16. Conclusions: NLR, MPV, and APACHE II at ICU admission are associated with mortality for critically ill patients with COVID-19.
