The success of SII, MII-1, MII-2, MII-3, and QT dispersion in predicting the walled-off pancreatic necrosis development in acute pancreatitis in the emergency department: An observational study.

walled-off pancreatic necrosis (WOPN) is one of the complications of acute pancreatitis (AP) with high mortality. A method to predict the development of WOPN in AP patients admitted to the emergency department may guide life-saving practices such as early initiation of antibiotic therapy and, when necessary, referral of the patient to a center where necrosectomy can be performed. This study is a prospective observational study. One hundred eleven AP patients who applied to the emergency department were included in the study. The mean of QT interval (QT) dispersion, systemic immune-inflammation Index (SII), multi-inflammatory index-I (MII-1), multi-inflammatory index-II (MII-2), and multi-inflammatory index-III (MII-3) were compared between patients who developed WOPN and patients who did not develop WOPN during their hospitalization. In the study, the mean of QT dispersion, SII, MII-1, MII-2, and MII-3 were significantly lower in the patient group who developed WOPN compared to those who did not develop WOPN. In the receiver operating characteristic analysis, all methods except SII were found to be successful in predicting WOPN. QT dispersion, SII, MII-1, MII-2, and MII-3 are valuable tools that provide rapid results and successfully predict the development of WOPN in AP. However, MII-2 and QT dispersion appears to be slightly more successful than the others.

Evaluation of the Reparative Effect of Sinomenine in an Acetaminophen-Induced Liver Injury Model.

Due to its rising global prevalence, liver failure treatments are urgently needed. Sinomenine (SIN), an alkaloid from sinomenium acutum, is being studied for its liver-repair properties due to Acetaminophen (APAP) overdose. SIN's effect on APAP-induced hepatotoxicity in rats was examined histologically and biochemically. Three groups of 30 adult male Wistar rats were created: control, APAP-only, and APAP + SIN. Histopathological and biochemical analyses were performed on liver samples after euthanasia. SIN is significantly protected against APAP damage. Compared to APAP-only, SIN reduced cellular injury and preserved hepatocellular architecture. The APAP + SIN Group had significantly lower ALT, MDA, and GSH levels, protecting against hepatocellular damage and oxidative stress. SIN also had dose-dependent antioxidant properties. When examining critical regulatory proteins, SIN partially restored Sirtuin 1 (SIRT1) levels. While BMP-7 levels were unaffected, histopathological evidence and hepatocyte damage percentages supported SIN's liver-restorative effect. SIN protected and repaired rats' livers from APAP-induced liver injury. This study suggests that SIN may treat acute liver damage, warranting further research into its long-term effects, optimal dosage, and clinical applications. These findings aid liver-related emergency department interventions and life-saving treatments.

The effect of stress hyperglycemia seen in acute ST-segment elevation in myocardial infarction on in-hospital mortality.

INTRODUCTION: The brief rise in blood glucose level during acute physiological stress in patients with no previous symptoms of diabetes mellitus is called stress hyperglycemia. METHODS: This study is conducted with 1033 patients over the age of 18 who are diagnosed with STEMI and who did not meet the exclusion criteria for 1 year. Patients were divided into 2 groups as DM and non-DM and their blood glucose levels, demographic data (age, sex, cardiovascular risk factors, DM, HT presence/absence, history of smoking), vital signs, fatal arrhythmia requiring intervention (ventricular tachycardia and ventricular fibrillation), cardiac insufficiency development according to Killip score, length of hospital stay, mortality and cardiogenic shock conditions were evaluated. Statistical analysis was made using SPSS 23.0 for Windows® (IBM Inc. Chicago, IL, USA). Results were considered significant at p < 0.05, with a 95% confidence interval. RESULTS: In non-DM group, BG has been found to be significantly higher in mortal cases compared to surviving cases (289.25 ± 106.35 mg/dL for mortal cases; whereas 156.99 ± 58.60 mg/dL for surviving cases; p < 0.001). Likewise, in DM group BG has been found to be higher in mortal cases compared to surviving cases. (328.38 ± 77.13 mg/dL for mortal cases while 237.16 ± 95.00 mg/dL for surviving cases; p < 0.001). CONCLUSIONS: For patients who are admitted to the hospital with STEMI, stress hyperglycemia in the non-DM group and hyperglycemia in the DM group are associated with both mortality and adverse conditions; thereby, glucose levels of those patients must be evaluated.

Antifibrotic preventive effect of polyethylene glycol (PEG) 3350 in methotrexateinduced hepatoxicity model.

PURPOSE: Liver damage caused by drugs and other chemicals accounts for about 5% of all cases. Methotrexate (MTX), a folic acid analogue, is a first-line synthetic antimetabolite agent routinely used in the treatment of rheumatoid arthritis and other autoimmune and chronic inflammatory diseases. Polyethylene glycol (PEG) has antioxidant activity. In this study, we evaluated biochemically and histopathologically the antifibrotic effect of PEG 3350 administered intraperitoneally to prevent methotrexate-induced liver damage in rats. METHODS: A total of 30 male rats including 10 rats was given no drugs (normal group), and 20 rats received single-dose 20 mg/kg MTXfor induced liver injury in this study. MTX was given to 20 rats, which were divided in two groups. Group 1 rats was given PEG30 mg/kg/day (Merck) intraperitoneally, and Group 2 rats % 0.9 NaCl saline 1 mL/kg/day intraperitoneally daily for two weeks. RESULTS: Transforming growth factor beta (TGF-ß), plasma malondialdehyde (MDA), liver MDA, serum tumour necrosis factor alpha (TNF-α), alanine aminotransferase and plasma pentraxin-3 levels and, according to tissue histopathology, hepatocyte necrosis, fibrosis and cellular infiltration were significantly better in MTX+PEG group than in MTX+saline group. CONCLUSIONS: PEG 3350 is a hope for toxic hepatitis due to other causes, since liver damage occurs through oxidative stress and cell damage, similar to all toxic drugs.

Rapid Shallow Breathing Index as a Predictor for Intubation and Mortality in Acute Respiratory Failure.

BACKGROUND: Noninvasive ventilation (NIV) is one of the most important therapeutic tools in patients with acute respiratory failure. However, in case of incorrect patient selection it can delay necessary intubation and is associated with complications and even mortality. Patient selection, therefore, plays a key role in therapeutic success. The purpose of this study was to determine the value of the rapid shallow breathing index (RSBI) in predicting the failure of NIV. METHODS: This prospective observational study was conducted in the emergency department (ED) of a tertiary hospital. Adults presenting to the ED with acute respiratory failure were included in the study. The success of RSBI values measured initially (RSBI 1) and at 30 min (RSBI 2) and the difference between these 2 values (Δ RSBI) in predicting subjects' intubation requirement and survival was tested using multivariate logistic regression analysis. RESULTS: Two hundred sixty-seven subjects were included in the study. RSBI 1, RSBI 2, and Δ RSBI values differed significantly between the intubated and non-intubated subjects. According to the multivariate model, RSBI 1 and RSBI 2 > 105, Δ RSBI < 19, heart rate > 100 beats/min, and SpO2 < 92% were significantly associated with intubation requirement. RSBI 1, RSBI 2, and Δ RSBI values also differed significantly between subjects with a fatal course and surviving individuals. According to the multivariate model, RSBI 2 > 105, Δ RSBI < 19, heart rate > 100, and increasing age were associated with in-hospital mortality. CONCLUSIONS: RSBI can be a successful marker in predicting the failure of NIV and predicting in-hospital mortality in patients admitted to the ED with acute respiratory failure.

The Evaluation of End Tidal Carbon Dioxide Values in Intubated Patients with COVID-19.

BACKGROUND: The aim of this study is to establish the value of PETCO2 in COVID-19 patients intubated in emergency department, and its effects on mortality.  Objectives: Between May 15, 2020 and January 15, 2021, The patients aged ≥18 years and diagnosed COVID-19, scheduled for urgent intubation in the emergency department were included. METHOD: Single-center, prospective and observational study. Age, gender, vital signs, laboratory findings are recorded. Immediately after intubation as measured by the capnography, the initial PETCO2_1 and at post-ventilation 15 min, PETCO2_2 and first, second arterial blood gas analysis are recorded. RESULTS: The mean age of the 48 patients was 74 years. The PETCO2_1 and PETCO2_2 measurements were statistically significantly different between the patients who survived and those who died (p=0.014, p=0.015). The patients with a high first PETCO2_1 value and a decrease to the normal level survived, but those with a low PETCO2_1 value that could not increase to a normal value died (p=0.038, p=0.031). Increased levels of SpO2, PETCO2_1, PETCO2_2 and PaCO2_2 decreased the risk of mortality, while an increased level of PaO2_2 increased the risk of mortality. CONCLUSION: Capnography is non-invasive and provides continuous measurement. Assessment of changes in PETCO2 value would contribute to patient survival.

Relationship between a Prolonged Corrected QT Interval and Mortality in Patients Presenting with Syncope at the Emergency Department.

BACKGROUND: Syncope is a common symptom in emergency department patients. Among various etiological factors, cardiac causes have the highest risk of mortality. The corrected QT interval is considered an independent predictor of mortality for many diseases. OBJECTIVES: Analyze QT interval analysis of patients presenting to the emergency department with syncope. METHODS: In this prospective observational study, patients who presented to the emergency department with syncope between January 1, 2018, and January 1, 2019 were included. RESULTS: The median age was 64 (49-78) years, and 58.8% of patients were male. The corrected QT interval (QTc) in patients with coronary artery disease and chronic obstructive pulmonary disease was longer than those without. There was no statistically significant association between hypertension, diabetes, stroke, thyroid disease, and prolonged QTc. Patients who did not survive had significantly prolonged QT intervals. According to ROC analysis, sensitivity of >440.5 ms QTc values in predicting mortality was 86% and specificity was 71% (AUC = 0.815; 95%CI = 0.71 - 0.91; p < 0.001). CONCLUSIONS: Patients admitted to emergency department with syncope and a prolonged QTc are associated with a higher mortality rate and thus can provide us with an important guide for the management of these patients.

The value of conventional manometry in the identification of normal esophageal manometry.

ABSTRACT: In the last decade, high-resolution esophageal manometry (HREM) is the main device for the management of dysphagia replacing conventional manometry (CM). Conventional manometry still seems to have some space to diagnose major motility disorders and differentiate normal from abnormal esophageal motility. The long term outcomes of patients with normal CM were analyzed in our study.Participants (patients with dysphagia and normal CM) took a questionnaire via a phone call in February 2021. Impact Dysphagia Questionnaire (IDQ) was used as an assessment tool.Only 55% (83/151) the individuals with previous normal manometric findings were reached via telephone. The group who have completed the survey was representative of the cohort. 66.2% of the participants were female (P = .40). The mean age was 57.21, mean weight was 70.69 kg, mean height was 163.74 cm and mean body mass index was 26.41. More than 40% of patients were completely asymptomatic at follow up, reflected by an IDQ score of 0. Only 28 out of 83 (33.7%) patients reported significant symptoms as reflected by an IDQ score greater than or equal to 7. The rest of responders admitted as having moderate to mild symptoms.HREM is a valid technique with comparable precision to CM. HREM measurements differ considerably to CM. The identification of normal motor function in CM is not likely a positive prognostic indicator and must be interpreted precautiously.

How would you like your COVID-19? From a host with mild course disease, or from a severe one?

The clinical course of COVID-19 presents a broad spectrum, being asymptomatic in some individuals while following a severe course and resulting in mortality in others. It is known that such factors as age and chronic diseases can result in a different clinical courses in individuals, however, variable clinical courses among the similar individuals in terms of age and chronic diseases are also seen. Other possible factors affecting the course of the disease that are mostly speculative or under investigation are genetic factors and the origin of transmission or possible subtype of novel coronavirus. Whether the source of transmission is important in the clinical course of the disease is unknown. A case series composed of seven individuals in a similar age group, with different lines of descent and different genetic structures, but who were infected from the same source is presented here. The similar and different clinical, laboratory and radiological findings of the cases residing in the same nursing home, who presented to the hospital altogether, were evaluated. The aim of the study was to analyze whether the source of transmission is influential in the clinical course of the disease.

Posterior reversible encephalopathy syndrome in a pregnant patient without eclampsia or preeclampsia.

Posterior Reversible Encephalopathy syndrome (PRES) is a rare neurologic disorder characterised by vasogenic edema in occipital and parietal lobes on MR. Patients usually complain about headache, visual disturbance, seizure and altered mental status. We repot a case of PRES seen in a pregnant patient. Although pre-eclampsia and eclampsia are among the common causes of this syndrome in this case patient was normotensive and no proteinuria was present. To our knowledge this is the first PRES case presented of a pregnant patient without eclampsia or pre-eclampsia.

Evaluation of the Diagnostic Role of Bedside Lung Ultrasonography in Patients with Suspected Pulmonary Embolism in the Emergency Department.

BACKGROUND: Despite the existence of detailed consensus guidelines, challenges remain regarding efficient, appropriate, and safe imaging methods for the diagnosis of suspected pulmonary embolism. AIMS: To investigate the role of the wedge sign, B-lines, and pleural effusion seen on bedside lung ultrasound in the diagnosis of pulmonary embolism. STUDY DESIGN: Diagnostic accuracy study. METHODS: During the first evaluation of patients with suspected pulmonary embolism, bedside lung ultrasound was performed, and the B-lines, wedge sign, and pleural effusion were investigated. Computed tomography angiography was used as a confirmatory test and was compared with the lung ultrasound findings. RESULTS: Pulmonary embolism was detected in 38 (38%) patients. In the comparison of bedside lung ultrasound results, statistically significant differences were found between the groups in terms of the B-lines and wedge sign (p=0.005 and p>0.001, respectively). There were no significant differences in terms of effusion (p=0.234). Comparison of these findings with computed tomography angiography of the chest showed weak negative correlations between the groups in terms of B-lines (r=-0297) and a moderately positive correlation in terms of the wedge sign (r=0.523). The sensitivity, specificity, and positive and negative predictive values of lung ultrasound findings alone were low. In the logistic regression analysis, the wedge sign (p>0.01, OR=69.45, 95% CI=6.94-695.17) and B-line (p=0.033, OR=1.96, 95% CI=0.41-8.40) were found to be effective in the diagnosis of pulmonary embolism. CONCLUSION: Although the role of lung ultrasound has been increasing in the management of critically ill patients, its value is limited and cannot replace the gold standard tests in the diagnosis of pulmonary embolism.

The relationship between optical coherence tomography patterns, angiographic parameters and visual acuity in age-related macular degeneration.

To assess the relationships between visual acuity (VA), fluorescein angiographic parameters and optical coherence tomography (OCT) patterns in exudative age-related macular degeneration (AMD). Fifty eyes with confirmed diagnosis of new exudative AMD who underwent fluorescein angiography (FA) and OCT evaluation were reviewed retrospectively. The greatest linear diameter of lesion (GLD) by FA and central foveal thickness (CFT) by OCT were measured. The OCT scans were evaluated for the presence of diffuse retinal thickening (D), cystic spaces (C), subretinal fluid (S) and pigment epithelial detachment (P) and five OCT patterns were detected (D + S; C; C + S; P + C + S; P + D + S). Angiographic classification of choroidal neovascularizations was performed. Correlations were statistically significant for VA and CFT in all patients whereas VA and GLD correlation was statistically significant only in predominantly classic and minimal classic lesions. The lowest VA values were detected in patients with COCT pattern and/or predominantly classic lesion type by FA. The OCT and FA findings when evaluated simultaneously may provide information regarding visual function in AMD.

Screening for retinopathy of prematurity in a tertiary hospital in Istanbul: incidence and risk factors.

PURPOSE: To study the incidence and risk factors of retinopathy of prematurity (ROP) in premature infants examined in a tertiary hospital in Istanbul. METHODS: Data of infants screened for ROP from April 2007 to September 2009 were retrospectively reviewed. Possible risk factors and eye examinations were recorded and analyzed using the chi-square test and univariate and multivariate regressions. RESULTS: ROP was detected in 177 (34.3%) of the 517 infants enrolled in the study; 64 had mild ROP (77.4%) and 38 had severe ROP (22.6%). The mean gestational age and birth weight of patients who were treated for ROP were 28.6 ± 2.3 and 1,143.5 ± 337.4, respectively. Two of these infants had a gestational age of 32 g or greater and three had a birth weight of 1,500 g or greater. The multivariate regression analyses showed gestational age, birth weight, sepsis, respiratory distress syndrome, and length of oxygen therapy as independent predictors of ROP. CONCLUSION: The incidence of ROP observed in this study was higher than that in developed countries and relatively more mature infants were affected. Criteria including gestational age of less than 34 weeks or birth weight of less than 2,000 g would have identified all infants who were at risk.
