A challenging issue in COVID-19 infection: The relationship between PA1-1 and TAFI levels in patients with coagulation disorder: A retrospective and observational study.

COVID-19 disrupts the balance between coagulation and fibrinolysis. Especially in the clinical course of serious disease, plasminogen activator inhibitor-1 (PAI-1), thrombin activatable fibrinolysis inhibitor (TAFI), and tissue plasminogen activator levels increase in association with hypercoagulable state and hypofibrinolysis. This explains the increased incidence of thrombosis seen in COVID-19 infection. In this study, we aimed to examine the changes in PAI-1 and TAFI levels of COVID-19 patients. Department of Infectious Diseases and Clinical Microbiology, University of Health Sciences, Diskapi Yildirim Beyazit Training and Research Hospital-Ankara Turkey, between April 1 and May 7, 2021. Patients who were diagnosed with COVID-19 were included in this retrospective study. TAFI and PAI-1 levels were analyzed from the samples that had been stored at -80 °C formerly. One hundred thirty-five patients diagnosed with COVID-19 and followed up in the service or intensive care unit were included in the study. Thirty-four (25.2%) patients required follow-up in the intensive care unit. Mortality rate was 10.4%, the coagulation tests of these patients were also compared. PA1-1 levels were found to be statistically significantly higher in intensive care unit patients (median: 133 pg/mL vs 31 pg/mL; P < .001), and there was no significant difference in TAFI levels (median:7.31 ng/mL vs 9.80 ng/mL; P = .171) between the 2 groups. TAFI levels were found to be higher in patients who died. In COVID-19 infection, as the severity of the disease increases, the coagulation balance deteriorates and eventually a hypercoagulable state occurs with an increase in PAI-1 and TAFI levels. Markers such as PAI and TAFI can be illuminating in further studies in determining prognosis and mortality and developing new treatment options.

Evaluation of adherence and attitudes of patients with allergic rhinitis to nasal steroid treatment.

BACKGROUND: Allergic rhinitis (AR) is defined as an inflammatory disease of the nose. Nasal corticosteroids (NCS) are one of the most effective drugs used in AR treatment. OBJECTIVE: One of the most important issues in the treatment of AR is patient adherence to NCS. We aimed to evaluate the adherence and attitude of patients with AR to NCS treatment. METHODS: One hundred four patients who were prescribed NCS for AR at any time and who used NCS during the study period were included in the study. Morisky Medical Adherence Scale-8 (MMAS-8) was performed on the patients to determine their treatment adherence. RESULTS: The scores of the MMAS-8 were below 6 in 55% of the patients, and the adherence of the patients to the NCS treatment was low. The adherence of the patients to NCS treatment was good in only 19% of the patients. As the duration of the disease increased, the adherence of the patients to the treatment decreased (p = 0.001). Patients who benefited from allergen immunotherapy had statistically significantly higher MMAS-8 scores than those who did not (p = 0.015). As expected, drug adherence was statistically significantly lower in patients with drug-related adverse effects (p = 0.01). Sixty percent of the patients had received NCS training, and MMAS-8 scores were significantly higher in those who received training (p = 0.023). CONCLUSION: Inadequate drug adherence is a challenging problem in the treatment of AR. Frequent evaluation of patients' drug adherence and drug use techniques in daily practice is important for the follow-up and treatment of the disease.

Comparison of deep learning-based recurrence-free survival with random survival forest and Cox proportional hazard models in Stage-I NSCLC patients.

BACKGROUND: The curative treatment for Stage I non-small cell lung cancer (NSCLC) is surgical resection. Even for Stage I patients, the probability of recurrence after curative treatment is around 20%. METHODS: In this retrospective study, we included 268 operated Stage I NSCLC patients between January 2008 and June 2018 to analyze the prognostic factors (pathological stage, histological type, number of sampled mediastinal lymph node stations, type of resection, SUVmax of the lesion) that may affect relapse with three different methods, Cox proportional hazard (CoxPH), random survival forest (RSF), DeepSurv, and to compare the performance of these methods with Harrell's C-index. The dataset was randomly split into two sets, training and test sets. RESULTS: In the training set, DeepSurv showed the best performance among the three models, the C-index of the training set was 0.832, followed by RSF (0.675) and CoxPH (0.672). In the test set, RSF showed the best performance among the three models, followed by DeepSurv with 0.677 and CoxPH methods with 0.625. CONCLUSION: In conclusion, machine-learning techniques can be useful in predicting recurrence for lung cancer and guide clinicians both in choosing the adjuvant treatment options and best follow-up programs.

The role of time interval elimination on pain control of preterm infants by sucrose administration.

PURPOSE: The 2-min time interval of sucrose administration given before minor painful procedures in preterm infants is based on a few limited studies. We aimed to assess availability of sucrose analgesia in emergency states of minor procedural pain by eliminating the 2-min time interval prior to heel lance in preterm infants. The primary outcome was Premature Infants Pain Profile-Revised (PIPP-R) at 30 and 60 s. METHODS: Healthy 69 preterms undergoing a heel lance, who were assigned randomly to 1 of 2 groups, i.e., group I, with the 2-min time interval of per oral 24% sucrose given prior to heel lance, or group II, without a time interval of per oral 24% sucrose, were recruited. Premature Infants Pain Profile-Revised, crying incidence, duration, and heart rate at 30 and 60 s following heel lance were the outcome measures in this single-center, randomized, prospective study. RESULTS: The 2 groups did not differ significantly in PIPP-R scores at 30 s (6.63 vs. 6.32, p = .578) and 60 s (5.80 vs. 5.38, p = .478). The crying incidence was similar between the 2 groups (p = .276). The median crying duration was 6 s (range: 1-13 s) in group I and 4.5 s (range: 1-18 s) in group II (p = .226). No significant differences in the heart rates between the 2 groups and the proportion of adverse events by time interval elimination were recorded. CONCLUSIONS: Eliminating the time interval did not decrease the analgesic effect of orally administered 24% sucrose given prior to heel lance. In emergency states of minor procedural pain, eliminating the 2-min time interval following sucrose administration is safe and efficacious in preterm infants.

Clinical, Functional, and Prognostic Evaluation of Idiopathic Pulmonary Fibrosis, Connective Tissue Disease-Associated Interstitial Lung Disease, Interstitial Pneumonia with Autoimmune Features: A Single-Center Prospective Study.

OBJECTIVE: Our study aimed to evaluate clinical, functional, and prognostic features and to determine the prognosis of idiopathic pulmonary fibrosis, connective tissue disease-associated interstitial lung diseases, and interstitial pneumonia with autoimmune features. MATERIAL AND METHODS: Sixty-nine cases with interstitial lung diseases were recruited in this study prospectively. Demographic features, symptoms, radiological findings, functional measurements, and immunological markers were recorded twice (at the time of initial admission and in the 12th month). Twenty-four of 69 cases were idiopathic pulmonary fibrosis, 32 were connective tissue diseaseassociated interstitial lung diseases, and 13 were interstitial pneumonia with autoimmune features . RESULTS: Most of the patients with idiopathic pulmonary fibrosis were male, while there were more female patients in connective tissue disease-associated interstitial lung diseases and interstitial pneumonia with autoimmune features groups. Female patients (65.0%) predominated in connective tissue disease-associated interstitial lung diseases group (P <.001). There was no significant difference in the mean ages of the disease groups, yet connective tissue disease-associated interstitial lung diseases patients were generally younger (min- max: 34-82 years). In the idiopathic pulmonary fibrosis group, only low titers of antinuclear antibody positivity were found. Antinuclear antibody positivity in the connective tissue disease-associated interstitial lung diseases group and interstitial pneumonia with autoimmune features group was high (P = .001). The long-term survival of idiopathic pulmonary fibrosis, connective tissue disease-associated interstitial lung diseases, and interstitial pneumonia with autoimmune features patients were 37%, 40 months (median) (95% CI, 5.193- 74.807), 48.6%, 80 months (median) (95% CI, 57.032-102.968), 30.8%, 46 months (median) (95% CI, 26.624-65.376), respectively. CONCLUSION: Although a consensus report describing interstitial lung diseases with autoimmune features has been published, diagnostic criteria for this group are still vague. Since the interstitial pneumonia with autoimmune features group had the worst results in terms of functional loss and survival rates, the follow-up parameters and follow-up algorithm should be established for this group. Clinical and immunological evaluation of the interstitial pneumonia with autoimmune features group should include detailed parameters because of follow-up and to estimate survival.

Relationship between palatally impacted canines and dimensions and morphology of sella turcica: A cone-beam computed tomography study.

INTRODUCTION: This study aimed to analyze the association of unilateral and bilateral palatal canine impaction with the dimensions and morphology of sella turcica from 3-dimensional cone-beam computed tomography (CBCT) images. METHODS: CBCT images of patients with bilateral (BPI) (n = 12; 9 female 3 male; 20.75 ± 5.88 years) and unilateral (UPI) (n = 35; 22 female 13 male; 19.28 ± 5.57 years) palatally impacted canines were compared with a control group (n = 56; 34 female 22 male; 20.82 ± 4.88 years). Linear measurements regarding sella turcica were made, and its morphologic variations were categorized. Two group comparisons were made with the Student t test or Mann-Whitney U-test, whereas one-way analysis of variance or Kruskal-Wallis tests were used for multiple group comparisons. Categorical variables were compared using the chi-square or Fisher exact test as appropriate. The binary logistic regression analyses and correlations using Spearman or Pearson correlation analyses were used to determine associations between variables (P <0.05). RESULTS: Sella diameter was significantly smaller in the BPI group compared to UPI and control groups. There was a significant association between sella diameter and BPI when compared with the control group (χ2[1] = 9.150; P = 0.008). There were no significant differences between groups in the distribution of sella turcica morphology. CONCLUSIONS: Despite the similar genetic origin of the sella turcica region and teeth, the association of palatal canine impaction with dimensions and morphology of sella turcica was weak. Both local and genetic factors might contribute to the ectopic position of the canine.

Prognostic value of systemic inflammatory response markers in cervical cancer.

We investigated the association between preoperative ratios of inflammatory markers and the prognosis in patients with invasive cervical cancer (CC). In this single-centre study, we retrospectively enrolled 163 CC patients who underwent radical hysterectomy between February 2008 and October 2018. Among the evaluated ratios, a high neutrophil-to-lymphocyte ratio (N/L) was significantly associated with deep stromal invasion and tumour size larger than 2 cm, whereas a high M/L was significantly related to advanced-stage CC (IB3-IIIC2), lymphatic metastasis (total) and pelvic lymph node metastasis (p= .002, p= .046 and p= .046, respectively). The neutrophil count plus monocyte-to-lymphocyte ratio (NM/L) and platelet-to-lymphocyte ratio (P/L) were significantly higher in patients with deep stromal invasion, advanced stage and tumour size larger than 2 cm (p=.01, p=.044 and p=.007; p=.004, p=.005 and p=.003, respectively). In the multivariate analysis, high NM/L (>168) was associated with a statistically significant hazard ratio of 3.04 (95% CI: (1.38-6.72); p=.006) for recurrence and 9.05 (95% CI: (2.10-38.99); p=.003) for death. Both stage and NM/L are independent prognostic factors that are significantly associated with recurrence and overall survival in CC.Impact StatementWhat is already known on this subject? Previous studies suggested that there is a relationship between inflammation and the formation, development and progression of cancer. However, the relationship between cervical cancer (CC) and inflammatory blood parameters is incompletely understood.What do the results of this study add? This study investigated the relationship between systemic blood inflammatory ratios and clinicopathological patient characteristics and disease outcomes in CC.What are the implications of these findings for clinical practice and/or further research? According to this study, systemic blood inflammatory ratios may help predict the prognosis and survival of patients with CC.

Choroidal structural alterations in diabetic patients in association with disease duration, HbA1c level, and presence of retinopathy.

PURPOSE: To assess choroidal structural changes in diabetic patients in association with disease duration, HbA1c level, and presence of retinopathy. METHODS: This retrospective cross-sectional study included treatment-naive patients with non-proliferative DR (NPDR) (group 1), diabetic patients without DR (group 2), and healthy subjects (group 3). Patients were also grouped according to the duration of diabetes: long-term group (> 15 years, n = 32) and short-term group (˂ 15 years, n = 28). The choroidal thickness was measured at three points; subfoveal, 1500 µm nasal, and 1500 µm temporal to the fovea. The choroidal area, stromal area, luminal area (LA), and choroidal vascularity index (CVI) were quantified using ImageJ. Partial correlation analysis and one-way analysis of covariance test were performed for statistical analysis. RESULTS: The study included 30 eyes of 30 treatment-naive patients with NPDR (group 1), 30 eyes of 30 diabetic patients without DR (group 2), and 30 eyes of 30 healthy persons (group 3). The mean subfoveal, nasal, and temporal choroidal thicknesses were decreased in group 1 in comparison with controls (p < 0.001, p = 0.035, and p = 0.005, respectively). The mean LA in group 1 and group 2 were both significantly lower compared to group 3 (group 1 vs. group 3, p = 0.004; group 2 vs. group 3, p = 0.020). CVI was significantly lower in group 1 and group 2 than in controls (group 1 vs. group 3, p = 0.019; group 2 vs. group 3, p = 0.025). CVI was significantly lower in the long-duration group than in the short-duration group (p < 0.001). A moderate negative correlation was found between the duration of diabetes and CVI (r = - 0.467, p < 0.001). A moderate negative correlation was found between HbA1c level and luminal area and CVI (r = - 0.466, p < 0.001, and r = - 0.425, p < 0.001, respectively). CONCLUSION: Choroidal structure and CVI are altered even in the absence of clinically confirmed retinopathy and these alterations are related to the duration of diabetes.

Risk Factors for Development of Biliary Stricture After Liver Transplant in Adult Patients: A Single-Center Retrospective Study.

Identification of risk factors for biliary stricture after liver transplant and its potential prevention is crucial to improve the outcomes and reduce the complications. We retrospectively analyzed donor and recipient characteristics with intraoperative and postoperative parameters to identify the risk factors for development of post-transplant anastomotic and nonanastomotic biliary strictures with additional analysis of the time onset of those strictures. A total of 412 patients were included in this study. Mean (SD) follow-up time was 79 (35) months (range, 1-152 months). Biliary stricture was diagnosed in 84 patients (20.4%). Multivariate analysis indicated that postoperative biliary leakage (odd ratio [OR], 3.94; P = .001), acute cellular rejection (OR, 3.05; P < .001), donor age older than 47.5 years (OR, 2.05; P = .032), preoperative recipient platelet value < 77.5 × 103/mL (OR, 1.91; P = .023), University of Wisconsin solution (OR, 1.73; P = .041)), recipient male sex (OR, 1.78; P = .072), portal/arterial flow ratio > 4 (OR, 1.76; P = .083), and intraoperative bleeding > 2850 mL (OR, 1.70; P = .053) were independent risk factors for biliary stricture regardless of the time of their appearance. Multiple risk factors for biliary stricture were determined in this study. Some of these risk factors are preventable, and implementation of strategies to eliminate some of those factors should reduce the development of post-transplant biliary stricture.

Macular structural changes and factors affecting final visual acuity in patients with Behçet uveitis.

PURPOSE: To evaluate macular structural changes during the active and remission periods in patients with Behçet uveitis and to further assess the factors affecting final visual acuity. METHODS: Clinical records and spectral domain-optical coherence tomography (SD-OCT) findings of patients with Behçet uveitis were retrospectively reviewed. RESULTS: Sixty-nine eyes of 35 patients were included in the study. SD-OCT findings in the active uveitis period included epiretinal membrane (ERM) in 26 (37.1%) eyes, ellipsoid zone (EZ) damage in 11 (15.7%), external limiting membrane (ELM) damage in 10 (14.3%), macular atrophy in 6 (8.6%), disruption of retinal pigment epithelium (RPE) in 11 (15.7%), a macular scar in 1 (1.4%), and loss of normal foveal contour appearance in 15 (21.4%). There was macular edema in 23 eyes (32.9%) in the active uveitis period (11 (15.7%) cystoid macular edema, 10 (14.3%) diffuse macular edema, and 7 (10.0%) serous retinal detachment). In the remission period, SD-OCT findings included ERM in 37 (52.9%) eyes, EZ damage in 14 (20%), ELM damage in 14 (20%), macular atrophy in 7 (10%), disruption of RPE in 14 (20.0%), macular scar in 1 (1.4%), and loss of normal foveal contour appearance in 17 (24.3%). The mean central macular thickness in the remission period was significantly lower than in the active uveitis period (p < 0.001). The presence of EZ damage and loss of normal foveal contour appearance in active uveitis period were the independent factors associated with final visual acuity (logMAR) (ß = 0.736, p = 0.003; ß = 0.682, p = 0.002, respectively). CONCLUSION: Ellipsoid zone damage and loss of normal foveal contour appearance are important factors affecting visual acuity in Behçet uveitis.

The Effect of Phenyramidol on Neural Development in Early Chicken Embryo Model.

AIM: To investigate the effects of Phenyramidol (Phe) on neural development in an early chicken embryo model. MATERIAL AND METHODS: Sixty fertile non-pathogenic Super Nick eggs were incubated for 24 hours (h) and divided into four groups of 15 eggs each. Phe was administrated through the sub-blastoderm, and the eggs were incubated for another 24 h. All eggs were opened after 48 h of incubation, and the embryos were evaluated morphologically and histopathologically. RESULTS: In Group 1 (control group), none exhibited neural tube defects (NTDs) (0%), 1 (6.6%) was undeveloped; in Group 2 (low dosages), 1 did not develop (6.6%); in Group 3 (normal dosages), 2 (13.4%) had NTDs, 1 (6.6%) was undeveloped; in Group 4 (high dosages), 5 (33.3%) had NTDs, 2 (13.3%) were undeveloped. CONCLUSION: In light of the results, it was determined that the use of increasing doses of Phe led to defects in midline closure in early chicken embryos. This is the first report in the literature on Phe used in an early chicken embryo model.

Hormone therapy following surgery in low-grade endometrial stromal sarcoma: Is it related to a decrease in recurrence rate?

BACKGROUND: Low-grade endometrial stromal sarcoma (LGESS) is, in most cases, a slow-growing malignancy; however, it is related with high recurrence rates. The aim of this study is to determine which factors may be associated with the recurrence rate of LGESS. METHODS: The clinicopathological features and treatment options in 37 patients with LGESS were evaluated. RESULTS: All patients underwent the hysterectomy and bilateral salpingo-oophorectomy. Additionally, lymphadenectomy was performed in 56.8% (n = 21) of the patients. Among the patients who underwent lymphadenectomy, 14.3% (n = 3) had lymph node metastasis. The disease was limited to the uterus in 75.7% of patients. Treatment following surgery was radiotherapy in three patients, chemotherapy in seven patients, hormone therapy in 12 patients, and chemotherapy plus hormone therapy in one patient. Megestrol acetate was used in all patients who received hormone therapy. Median follow-up time was 96 months. The 5-year disease-free survival and disease-specific survival were 72% and 97%, respectively. The recurrence rate was 27%. Only hormone therapy following surgery was significantly associated with a lower recurrence rate, even in patients with stage 1 disease. None of the patients treated with hormone therapy following surgery had recurrence, whereas recurrence occurred in 38.5% of the patients who underwent surgery only (p = 0.039). CONCLUSION: Hormone therapy after surgery should be considered a viable option for decreasing the LGESS recurrence rate, regardless of the disease stage.

Independent predictors of survival in endometrium cancer: platelet-to-lymphocyte ratio and platelet/neutrophil/monocyte-to-lymphocyte ratio

Objective: To evaluate the association between ratios of inflammatory markers and survival in endometrium cancer (EC). Material and Methods: Four hundred ninety-seven patients with epithelial EC were included. The evaluated ratios were neutrophil (N)/lymphocyte (L), neutrophil count divided by the lymphocyte count; platelet (P)/lymphocyte, platelets divided by the lymphocyte count; lymphocyte/monocyte (M), lymphocytes divided by the monocyte count; NM/L, neutrophil plus monocyte divided by the lymphocyte count; PNM/L, the sum total counts of platelets, neutrophils and monocytes divided by the lymphocyte count. Results: The median follow-up time was 24 months (1-129). Recurrence and exitus occurred in 34 (7%) and 18 (3.7%) patients, respectively. Metastasis in pelvic or para-aortic lymph nodes were significantly related only with low L/M. None of the inflammatory ratios were associated with disease-free survival. In multi-variant analysis, only high P/L (>168) and high PNM/L (>171) were related with a statistically significant hazard ratio for death of 2.91 (p=0.024) and 2.93 (p=0.023), respectively. Conclusion: The P/L and PNM/L were in relation with worse overall survival and also independent prognostic factors for OS.
