The role of platelet large cell ratio in determining mortality in COVID-19 patients. Medicine (Baltimore) 2024; 103:e38033. [PMID: 38701279 PMCID: PMC11062659 DOI: 10.1097/md.0000000000038033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 04/05/2024] [Indexed: 05/05/2024] Open
Abstract
Inflammatory mechanisms have been implicated and have been subject to research in the clinical course of COVID-19 patients. In this study, platelet large cell ratio (P-LCR) has been examined as a novel prognostic and inflammatory parameter. A total of 1992 COVID-19-positive patients admitted to COVID-19 unit of Infectious Diseases were included. In order to identify a potential relationship between P-LCR and mortality, surviving patients were compared with subjects who died as a result of the disease. Although P-LCR levels showed a steady increase in all COVID-19 patients after admission, they were significantly higher in those who eventually died (P < .001), indicating a positive correlation between mortality and P-LCR. The P-LCR levels of patients followed up in the intensive care unit were statistically significantly higher than those followed up in the ward (P < .001). P-LCR levels of patients intubated in intensive care unit were statistically significantly higher than those who were not intubated (P < .001). Also, P-LCR levels were subdivided into 3 categories as normal, low, and elevated. Elevated P-LCR was found to be positively correlated with leukocyte count, neutrophil count, D-dimer, troponin, ferritin, and C-Reactive Protein (CRP) and showed negative correlation with fibrinogen, lymphocyte count, and platelet count. As P-LCR was correlated with the severity of inflammation in all COVID-19 patients, it was significantly higher in those patients who died. Elevated P-LCR was considered to be associated with the risk of severe disease and death. This inexpensive, readily available test may be incorporated into our clinical practice as a novel marker of poor prognosis in addition to other valuable laboratory parameters.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of Troponin-T levels on the prognosis of neonatal encephalopathy (NE). PATIENTS AND METHODS The study included one hundred and eleven newborns diagnosed with NE and receiving hypothermia treatment. The cases were separated into 2 groups according to the SARNAT classification as Stage 2 or Stage 3. The groups were compared in respect of anthropometric characteristics, APGAR scores, and biochemical parameters. The cases were also separated into 3 groups according to the Troponin-T levels and were compared with respect to the clinical course. RESULTS The serum Troponin-T (p=0.012), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (p<0.0001), and lactate levels (p=0.04) in the Sarnat Stage 3 group were statistically significantly higher than in the Sarnat stage 2 group. A significant positive correlation was determined between the Troponin-T level and the total duration of respiratory support (r=0.20, p=0.03). A significant positive correlation was determined between the ALT/AST ratio and the length of stay in hospital (r=0.29, p=0.001), duration of intubation (r=0.32, p=0.01), and total duration of respiratory support (r=0.36, p<0.001). A statistically significant difference was determined in mortality rates between the 3 subgroups of Troponin-T levels; Group 1: 2.8%, Group 2:5.4%, and Group 3: 15.8%. (p=0.04, χ²=4.74). A cut-off value of 164 ng/L for Troponin-T was determined to predict mortality with 77% sensitivity and 67% specificity (AUC=0.73, p=0.023). When the groups were compared according to Troponin-T level, a statistically significant difference was determined in respect of length of stay in hospital (p=0.03, χ²=6.95) and total duration of oxygen support (p=0.01, χ²=9.12). CONCLUSIONS The serum Troponin-T level can be evaluated as a prognostic marker in cases followed up with a diagnosis of NE and receiving hypothermia treatment. There is a need for further prospective studies with larger samples on this subject.

Abstract
OBJECTIVE Crimean-Congo Hemorrhagic Fever (CCHF) is a potentially fatal zoonotic viral disease involving fever and hemorrhage. Our aim was to investigate the relationship between interleukin (IL)-1 and IL-1 receptor antagonist (RA) levels in patients with CCHF and the course of the disease and mortality, as well as to contribute to the literature at a time when new therapeutic protocols are being investigated. PATIENTS AND METHODS Sixty-one patients with CCHF were admitted to our hospital's infectious diseases ward between March and September 2022, and 40 healthy people were included in the control group in our study. The patients were divided into mild/moderate (n=35) and severe (n=26) CCHF groups depending on the clinical course. The patients with CCHF were also divided into surviving and exitus groups. IL-1 and IL-1RA levels were measured from blood specimens using the ELISA method. RESULTS Significant elevation in IL-1 and IL-1RA levels was observed in CCHF cases with a severe manifestation compared to those with moderate disease. Both patient groups' IL-1 and IL-1RA levels were also significantly higher than those of the control group. In addition, IL-1 and IL-1RA levels were significantly higher among the exitus patients compared to the surviving CCHF patients. The laboratory values of lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine phosphokinase (CK), platelet count, prothrombin time (PT), and activated partial thromboplastin time (aPTT) were also significantly higher among the patients with severe manifestations compared to the moderate severity patient group, and in the exitus patients compared to the survivors. However, platelet count and fibrinogen levels were lower in the patients with a severe manifestation compared to the moderate severity group and in the exitus patients compared to the survivors. White blood cells (WBC) were higher in exitus patients than in survivors. CONCLUSIONS IL-1 and IL-1RA levels were elevated in all the CCHF patients, while the higher values in patients with a fatal course suggest that the inflammatory process is very severe and that IL-1 receptor antagonists may be needed in the treatment.

Abstract
BACKGROUND This study examined the relationship between levels of the chemokines CXCL9, CXCL10, CXCL11, and CXCR3 and mortality in patients with COVID-19.. METHODS A total of 71 patients hospitalized with COVID-19 and 35 health workers with no symptoms and negative SARS-CoV-2 PCR results were included in the study. CXCL9, CXCL10, CXCL11, and CXCR3 levels were measured in blood samples using enzyme-linked immunosorbent assays. Participants were divided into three groups: healthy individuals, patients with mild to moderate pneumonia, and patients with severe pneumonia. Patients were also divided into sub-groups according to the outcome: dead and survived. RESULTS Serum CXCL9, CXCL10, CXCL11, and CXCR3 levels were significantly higher in patients with severe COVID-19 than in those with non-severe COVID-19; were higher in both patient groups than in the control group; and were higher in patients who died than in those who survived. Lymphocyte counts, and fibrinogen and PaO2/FiO2 levels were significantly lower in patients with severe COVID-19 than in those with moderate disease. Patients with COVID-19 also had elevated neutrophil/lymphocyte ratios, neutrophil counts, and lactate dehydrogenase, C-reactive protein, D-dimer, and ferritin levels. CONCLUSIONS This study confirmed that CXCL9, CXCL10, CXCL11, and CXCR3 levels are associated with disease severity in patients with COVID-19. These laboratory parameters can help to estimate disease severity and predict outcomes, and are useful in clinical decision-making.

Abstract
OBJECTIVE This study aimed to investigate the frequency of sleep disorders, and the relationship between glycemic control and sleep characteristics in diabetic children and adolescents. PATIENTS AND METHODS Sixty-one patients followed for at least one year for type 1 diabetes mellitus (T1DM) aged 6-16 years old, and eighty-three group-matched healthy controls were included in the study. Time in range (TIR) and hypoglycemia episode numbers were recorded using the freestyle libre sensor data. The sleep characteristics were evaluated using the Sleep Disturbance Scale for Children (SDSC) validated survey. The diabetic patients were trichotomized according to SDSC scores, as low, medium, and high score groups. RESULTS Sleep duration, SDSC total score, and subgroup scores except for sleep hyperhidrosis (3.11±1.53 vs. 2.16±0.85, p<0.001, respectively) were similar (p>0.05) between the diabetic and control group. According to the survey, 1.6% of diabetic cases and 6.1% of the control group had clinically significant sleep disturbances (p>0.05). Duration of diabetes (DD) was lower (p=0.01), and the level of HbA1C was higher (p=0.02) in the high-score group than the others. Regression analysis revealed that TIR was the only independent determinant for the SDSC score (β=-1.27, t=-1.90; p=0.012). CONCLUSIONS Sleep habits and problems should be routinely evaluated in diabetic children and adolescents.

Abstract
Brusellosis is the world's most common bacterial zoonotic infection and is still endemic in many developing countries. The clinical appearance of brucellosis is not specific, but the course and severity of the infection varies. In this study, it was aimed to determine the relationship between laboratory parameters and clinical response and organ involvement in patients with Brucellosis diagnosed with specific diagnostic tests. In the study, 100 patients without previous diagnosis of Brucellosis who have admitted to the Department of Infectious Diseases and Clinical Microbiology and had positive Brucella tube agglutination tests and whose clinic was compatible with Brucellosis were evaluated prospectively. Patients were invited to be checked in the 1st, 2nd and 6th weeks . Patients with hip pain and low back pain were evaluated with sacroiliac magnetic resonance imaging (MRI) and lumbar MRI for sacroiliitis and spondylodiscitis. Patients with liver and bone marrow involvements, sacroiliitis, spondylodiscitis and orchitis were recorded as the patients with organ involvement. After six weeks, the decline of the complaints was considered as a clinical response. In the 6th week of the treatment, it was observed that platelet distribution width (PDW) and mean platelet volume (MPV) levels were lower in patients with a clinical response compared to the patients with no clinical response which was statistically significant (p= 0.01, p= 0.02). Platelet and platelet lymphocyte ratio (PLR) level in patients with organ involvement in the 1st and 6th weeks of the treatment, were observed to be lower than the patients without organ involvement which was statistically significant (week 1: p= 0.001, p= 0.01; week 6: p= 0.03, p= 0.01). Among patients with organ involvement and non-organ involvement, the area under the curve was 66% in the ROC curve analysis for PLR at the onset of the treatment. When the cut-off value was taken as 128.8%, the sensitivity was 55%, and the specificity was 78%. Depending on the level of platelet at the beginning of the treatment, in the ROC curve analysis carried out among patients with organ involvement and non-organ involvement, the area under the curve was 73% and when the cut off value was taken as 256000, the sensitivity was 71%, and the specificity was 68%. In the 6th week of the treatment, the area under the curve was observed as 67% in the ROC curve analysis of the PDW level among patients from whom clinical responses were received and not received. When the cut-off value was taken as 10.75%, the sensitivity was 65%, and the specificity was 70%. In the ROC curve analysis of the MPV value for clinical response, the area under the curve was 66%, and when the cut-off value was taken as 9.95, the sensitivity was observed as 52%, and the specificity was 74%. As a result, in the evaluation of the clinical response, which is important in the termination of the treatment in patients with Brucellosis, the use of MPV and PDW values in the evaluation of organ involvement and platelet level and PLO in the follow up, are cheap, easily accessible biomarkers that can be used clinically.

Influence of resveratrol application with pulp-capping materials on the genetic expression levels of stem cells. Int Endod J 2020; 53:1253-1263. [PMID: 32515014 DOI: 10.1111/iej.13345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 06/03/2020] [Accepted: 06/03/2020] [Indexed: 11/30/2022]
Abstract
AIM To evaluate in a laboratory setting the response of human mesenchymal stem cells (MSCs) to pulp-capping materials with and without resveratrol (RSV). METHODOLOGY Five materials, Calcimol LC, Life, TheraCal LC, ProRoot MTA and Biodentine, were prepared according to the manufacturers' instructions. Human MSCs were then exposed to these materials, with and without RSV, for 24 h (n = 8). Cell viability was evaluated using the MTT assay, and total cell death was quantified by annexin V-FITC staining with flow cytometry. The expression levels of the IL-8, IL-10, HBD-2 and BCL-2 genes were investigated using real-time polymerase chain reaction (RT-PCR). Data obtained from MTT test were analysed using one-way anova, and Tukey's multiple-comparison test. The paired Student t test was employed to compare the effects of materials on gene expression (significance level of 5%). RESULTS The group cell viabilities were Calcimol LC 53%, Life 43%, TheraCal LC 78%, ProRoot MTA 75% and Biodentine 78%. Calcimol LC and Life exhibited significant differences compared with the control groups (P < 0.05). The percentages of necrotic/late apoptotic cells associated with Calcimol LC and TheraCal LC were greater than in the other materials. However, when RSV was added to wells containing materials, cell viability increased to Calcimol LC 63%, Life 52%, TheraCal LC 82%, ProRoot MTA 91% and Biodentine 96%, and the percentages of early apoptotic and late apoptotic/necrotic cells decreased. Calcimol LC + RSV and Life + RSV differed significantly from the control group (P < 0.05). The expression of IL-8 gene was high for all materials, ProRoot MTA caused significant overexpression, and the addition of RSV reduced the expression of IL-8 in the Calcimol LC, TheraCal LC and ProRoot MTA groups and led to increased expression of IL-10 in the Calcimol LC, Life and Biodentine groups. HBD-2 and BCL-2 exhibited increased expression in ProRoot MTA with RSV (P < 0.05). CONCLUSIONS The addition of RSV exerted a protective effect on MSCs and regulated the inflammatory process by altering the expression levels of pro- and anti-inflammatory genes.

Abstract
Objective: The aim of the study is to evaluate temperature change in fiber-reinforced composite (FRC) resin photopolymerized with a light-emitting diode (LED) light-curing unit (LCU). Materials and Methods: Forty dentine disks (1 mm thick and 8 mm diameter) were prepared from human molars. The FRC specimens (2 mm thickness and 8 mm diameter) consisted of polyethylene fiber (Construct (CT)) products or glass fiber (ever Stick (ES)) and one hybrid composite bonded to the dentin disks and polymerized with an LED LCU. Control groups were prepared using the hybrid composite. Temperature rise in dentine samples under the FRC bonded disks was measured using a K-type thermocouple, and data were recorded. Temperature change data were subjected to analysis of variance (ANOVA) and Duncan's test. Results: The results show that addition of fiber (one or two layers) did not change temperature rise values at any of the exposure times (P > 0.05). The CT fiber/two layer/40 s group exhibited the greatest temperature rise (5.49 ± 0.62) and the ES/one layer/10 s group the lowest rise (1.75 ± 0.32). A significant difference was observed in temperature rise measured during 10 and 20 s exposures (P < 0.05). Conclusion: Maximal temperature rise determined in all groups was not critical for pulpal health, although clinicians need to note temperature rises during polymerization.

Abstract
Pneumococcal meningitis does continue to be an important cause of mortality and morbidity in childhood despite widespread vaccination. It develops thorough invasion of the meninges by the agent via bloodstream. It may manifest typical signs of meningeal irritation and even the symptoms not belonging to the central nervous system, such as diarrhea. The diagnosis is made by microscopic evaluation and culture of cerebrospinal fluid (CSF) obtained by lumbar puncture. Despite the treatment, the risk of occurrence of cerebral and neurologic complications is high. A two-month old baby girl was presented to our outpatients' clinic because of fever and diarrhea; she was diagnosed with pneumococcal meningitis and developed cerebral infarct during surveillance. The reason why we presented this patient is to highlight that meningitis due to pneumococ, one of the most common causing agents in childhood meningitis, may have clinical presentations other than expected. Key words: Pneumococcal meningitis; cerebral infarct; infant. DOI: 10.3329/bjms.v10i1.7320 Bangladesh Journal of Medical Science Vol.10 No.1 Jan 2010 pp.52-56
