Neutrophil/lymphocyte ratio and Red blood cell distribution width are independent risk factors for 30-day mortality in Gastrointestinal system bleeding patients

Abstract

Background. In this study, we aimed to examine demographic and endoscopic features of patients with GI bleeding to determine the factors affecting 30-day mortality.
Method. Patient’s demographic features, laboratory outcomes, comorbidities, drug use, endoscopy outcomes, Glasgow-Blatchford scores, and mortality status were examined. The factors affecting 30-day mortality were investigated.
Results. The mean age of the patients was 58.2±17.4 years, and 72.1% were male patients. 30-day mortality rate was found to be 14.4%. The mean age of patients who died was high (p<0.05). The incidence of mortality was high in the presence of comorbidity, malignancy, and cirrhosis (p<0.05). Systolic blood pressure was low in the patients who died (p<0.05). No significant correlation was found between mortality and gender, symptoms, predisposing factors, lesion type and Forrest score, diastolic blood pressure and heart rate (p>0.05). Urea, neutrophils, red blood cell distribution width / platelet ratio, neutrophil / lymphocyte ratio and RDW levels were high, and hemoglobin level was significantly low in patients with a mortal progression (p<0.05). No significant correlation was found between mortality, and platelet and lymphocyte levels (p>0.05). Glasgow-Blatchford score was significantly higher in patients who died (p<0.05).
Conclusion. Many factors affect 30-day mortality in GI bleeding. It should be remembered that follow-up of patients with an advanced age who have comorbidity and impaired hemodynamics should be kept for long, and that these patients are at a high risk for mortality.
According to our results, NLR and RDW are independent factors that determine the 30-day mortality in upper GI bleeding.

Can echocardiographic assessment of interatrial septum shape and motion improve the accuracy of the BLUE protocol?

Abstract

Acute respiratory failure is one of the most challenging critical conditions due to a wide variety of differential diagnosis. Bedside lung ultrasound in emergency (BLUE) protocol allows accurate differentiation between the most common underlying causes of acute respiratory failure in up to 90% of the cases. The assessment of left atrial pressure affecting left ventricular filling is essential in critically ill patients guiding volume substitution, optimization of left ventricular function and prevention of pulmonary congestion, thus ensuing haemodynamic stability. A simple, non-invasive method of left atrial pressure evaluation is the echocardiographic assessment of interatrial septum shape and motion, which is affected by interatrial pressure gradient. Aiming to improve the accuracy of the BLUE protocol, we propose the simple, non-invasive echocardiographic assessment of interatrial septum shape and motion as an upgrade, providing additional information of the loading of left and right atrium thus distinguishing the most common causes of acute respiratory failure.

An Unnoticed Case; Hypermagnesemia at the Emergency Department

Abstract

Introduction. Hypermagnesemia generally develops in people with renal function disorders or due to exogen Mg intake for constipation. Hospitalized cases of fatal hypermagnesemia are rare in the literature. The aim of this case report was to see if fatal progression could be due to delayed diagnose.

Case Presentation. A 61 year old woman presented at the emergency department (ED) for the evaluation of her symptoms which were leg pain, weakness, nausea, constipation and general debility. In her prior history, she had used magnesia calcine for laxative until two weeks before. Electrocardiography showed atrial fibrillation with high ventricular respond (HVRAF). Initial serum magnesium (Mg) concentration was 6.80 mEq/l. 10% calcium gluconate with 20 ml used to antagonize symptoms for treatment. Intravenous (IV) metoprolol was used for HVRAF but the patient was unresponsive. On the second day Mg rose to 7.06 mEq/l. The patient’s consciousness was altered, she developed lethargy, and hemodynamic instability was revealed. In addition, respiratory distress was present and patient was intubated. Therefore, she was diagnosed with a suspected Mg intoxication due to laxative use. Continuous hemodiafiltration (CHDF) was urgently used to decrease Mg. On the third day the patient was unresponsive to the treatment and died in intensive care unit (ICU).

Conclusion. Patients with nonspecific symptoms due to a prolonged laxative use can be admitted to the ED. Hypotension, altering consciousness and cardiac dysthymias can be revealed quickly and therefore the progress is fatal. Mg intoxication must be noticed early in the ED. IV calcium directly antagonises the effects of magnesium. It can reverse effects such as cardiac arrhythmias. IV normal saline must be used for supportive treatment and if those not responding to intravenous calcium and other supportive measures, CHDF must be used urgently for all patients with features of life threatening hypermagnesemia.

Prophylactic use of the probiotic strain Lactobacillus casei rhamnosus as part of a triple anti-infective regimen in very preterm infants during neonatal intensive care

Abstract

Background. Probiotics are increasingly used in neonatal intensive care and prove to reduce rates of necrotizing enterocolitis (NEC), sepsis and all-cause mortality by meta-analyses.

Objective. Aim of the study was to analyze the prophylactic use of the probiotic Lactobacillus casei rhamnosus (LCR) as part of a triple anti-infective treatment regimen in very preterm neonates in respect to complications and possible side effects.

Setting. This was a study on 1169 very preterm infants of 32 weeks of gestational age and less born between 2005 and 2015 who were admitted within the first 24 hours of life to the neonatal intensive care unit (NICU) and hospitalized for at least 7 days.

Design. Retrospective observational STROBE compliant single-center cohort study

Intervention. All infants received a standardized prophylactic anti-infective treatment regimen with enteral probiotics (LCR), antifungal agents, and oral gentamycin over the study time starting at the first day of life.

Outcome measures. Perinatal and neonatal data were collected for descriptive analysis. Complications possibly avoided by the anti-infective regimen included NEC, late-onset sepsis (LOS), late-onset multiple organ dysfunction syndrome (MODS), and ventilator associated pneumonia (VAP).

Main results. Eleven of 1169 infants 11 (0.9%) had diagnosis of NEC ≥ IIa, 141 (12.1%) exhibited at least one episode of LOS, 31 (2.7%) a VAP, and 44 (3.8%) a MODS. Those infants with complications were of younger gestational age (p<0.001), had lower birth weight (p<0.001), lower Apgar scores at 1/5/10 minutes (p<0.001), were more common SGA (p=0.007), had longer courses of mechanical ventilation and longer hospital stays and for longer time parenteral antibiotics (all p<0.001). Mortality rate was increased in infants having experienced complications (6.9 vs. 1.7%, p<0.001).

Conclusions. Over an 11-year period, the use of the probiotic LCR as part of an anti-infective regimen was safe and resulted in low rates of NEC, LOS, VAP, and MODS compared to the literature. Those infants with complications had higher mortality rates.

The Importance of Bedside Ultrasonography in Confirming the Location of Endotracheal Tube

Abstract

Objective. Endotracheal intubation may be associated with lethal complications when not applied in appropriate manner. In this study, we aimed to examine the efficiency of transcricoid and pulmonary ultrasonography in confirming the position of the tube in comparison with classical methods.

Methods. This study was carried out between 2016 and 2017 in Turkey and was registered in Clinical Trials under number NCT03081221. The location of the tube was confirmed using methods such as monitoring the vocal cords during direct laryngoscopy, condensation on endotracheal tube during respiration, epigastric-pulmonary auscultation, radiography and capnometry. After that, the transcricoid and pulmonary ultrasonography were implemented by the blinded pediatric emergency care specialist.

Results. 64 cases who needed advanced airway requirements were involved in this study. The double-line appearance could not be obtained from one patient only when using transcricoid ultrasonography, but the bilateral pleural shift movement was observed among all the cases by using pulmonary ultrasonography (sensitive: 98%-100%).

Conclusion. The determination of endoesophageal, endotracheal and endobronchial intubations can be easily made by using transcricoid and pulmonary ultrasonography. The use of ultrasonography may significantly contribute to critical airway management as fast, accurate and on time.

Keywords: Endobronchial intubation, Endotracheal intubation, Ultrasonography.
