Abstract
BACKGROUND To investigate the mechanism of action of stathmin1 (STMN1) in mesothelioma (MSM) and whether it has any role in its treatment. METHODS STMN1 expression was examined using immunohistochemistry in biopsy tissues taken from MSM patients. The relationships between the levels of STMN1 expression in the pathology preparations of MSM patients, and the clinicopathological characteristics of these patients, and their survival times were investigated. Transfection of STMN1-specific siRNA into SPC212 cells was compared to negative control siRNAs. The mRNA levels of genes that may play a role in invasion, apoptosis, and autophagy were evaluated by RT-PCR. RESULTS The expression of STMN1 was shown to be high in MSM tissues (p < 0.05). It was found that the only independent predictor factor affecting the survival time of MSM patients was the disease stage (p < 0.05). STMN1 was significantly reduced after siRNA intervention (81.5%). STMN1 with specific siRNA has been shown to suppress invasion by reducing the mRNA levels of cadherin-6 (CDH6), fibroblast growth factor-8 (FGF8), hypoxia-inducible factor 1 (HIF1A), matrix metallopeptidase 1-2 (gelatinase A) (MMP1-2), and TIMP metallopeptidase inhibitor 2 (TIMP2), which are important markers for invasion. Although the expression of apoptosis and autophagy-related genes, caspase-2 (Casp2) and LC-3, was reduced by silencing STMN1 with specific siRNA in western blot analysis, this effect was not observed in PCR results. CONCLUSIONS Immunohistochemical analysis of STMN1 may contribute to the differential diagnosis of MSM, and STMN1 may also be considered as a potential therapeutic target in the early invasive stage of MSM therapy.

Abstract
OBJECTIVE Cancer patients are among the high-risk groups where COVID-19 infection tends to be severe and can lead to increased mortality. Therefore, they are included in the priority groups for COVID-19 vaccination. This study aimed to compare the levels of SARS-CoV-2 immunoglobulin G (IgG) antibodies following two different COVID-19 vaccinations between hematology-oncology patients and healthcare personnel and to identify factors associated with these antibody levels. PATIENTS AND METHODS A prospective study was conducted with 91 hematology-oncology patients (cancer group) and 75 healthcare personnel (control group) from January 2020 to June 2023. The cancer and control groups comprised adults who had received a booster dose, with either a single dose of BNT162b2 or two doses of CoronaVac™ spaced one month apart, following their primary vaccination with two doses of either CoronaVac™ or BNT162b2. Four weeks after the administration of the booster dose, levels of SARS-CoV-2 IgG antibodies were assessed using an ELISA kit. Antibody levels above 50 AU/mL were accepted as signifying seropositivity. RESULTS The median SARS-CoV-2 IgG antibody level was lower in the cancer group compared to the control group (4,509 vs. 7,268, p = 0.004), while the rate of seroconversion was similar between the groups (97.8% vs. 100%, p = 0.564). In the cancer group, no association was found between SARS-CoV-2 IgG antibody levels and age, sex, comorbidity, type of malignancy, stage and duration, or type of vaccine. CONCLUSIONS In cancer patients, the seroconversion positivity rate was about 98%. However, antibody responses were still lower compared to the control group. No difference was detected in antibody levels among cancer patients based on the type of vaccine.

Abstract
OBJECTIVE Cyclin D1 (CDDN1) is a protein required for mitotic cell cycle progression through the G1 phase, as well as a regulatory component of the cyclin-dependent kinases CDK4 and CDK6. In this study, we wanted to evaluate the relationship between CDDN1 expression and clinicopathological features in breast cancer (BC) cases and whether CDDN1 could be used as a prognostic biomarker for BC cases. METHODS A total of 70 cases, 30 cases each with limited and advanced-stage BC, and as the control group, 10 healthy breast tissue, without a cancer diagnosis, with examined for benign reasons (mammoplasty, breast reduction surgery, etc.) were included in this study. The pathological specimens from the cases were stained, immunohistochemically, and categorized as a "low" (L) group or a "high" (H) group for CDDN1 expression. The cases' clinicopathological features and survival rates were evaluated statistically, within a 95% of confidence interval, p<0.05, retrospectively. RESULTS The median follow-up period of the cases was 48.00 (range, 6-150) months. CDDN1 expression was significantly higher in advanced-stage BC cases than in normal breast tissue and limited-stage BC cases. The median overall survival (OS) was 96 months (CI 95%: 67.74-117.59) in the H-CDDN1 group, compared to the L-CDDN1 group not reached, but there was no relation (p>0.05). CDDN1 overexpression was more prominent in low-grade advanced BC cases (p=0.004). The median OS of advanced-stage BC cases with Grade 1 was significantly longer than those with other grades (p=0.04). CONCLUSION Our results suggest that CDDN1 expression can be used as a potentially appropriate positive prognostic biomarker for advanced-stage BC cases.

Abstract
BACKGROUND Pancreatic and colon cancer are among important gastrointestinal cancer diseases. Pain, fatigue, and insomnia are among the most common symptoms in cancer patients receiving chemotherapy. Self-acupressure may improve patients' pain, fatigue, sleep quality, quality of life, and functional well-being. OBJECTIVE The aim of this study was to examine the effects of self-acupressure application on pain, fatigue, and sleep quality in colon and pancreatic cancer patients receiving chemotherapy. METHODS This randomized controlled study was conducted with 60 patients in treatment for pancreatic or colon cancer, 30 in the intervention and 30 in the control group, between June and October 2021. Participants in the intervention group were asked to complete 16 acupressure sessions for 4 weeks, 2 days a week in the morning and afternoon for a total of 18 minutes, depending on the preparation and pressure time on 4 pressure points. Control group participants did not receive any interventions during the study. The data were collected by using a personal information form, the Pittsburgh Sleep Quality Index, the Piper Fatigue Scale, and the visual analog scale. RESULTS After self-acupressure, the visual analog scale, Piper Fatigue Scale, and Pittsburgh Sleep Quality Index scores of the intervention group decreased when compared with the control group scores; the difference between the 2 groups was statistically significant. CONCLUSION Self-acupressure was effective in reducing the pain, fatigue, and sleep disorder scores of patients with colon or pancreatic cancer receiving chemotherapy. IMPLICATIONS FOR PRACTICE In nursing practice, self-acupressure, an applicable, accessible, and inexpensive method in the management of cancer-related symptoms, can be supported and maintained during a 4-week period.

Abstract
BACKGROUND Severely calcified coronary lesions present a particular challenge for percutaneous coronary intervention. AIMS The aim of this randomized study was to determine whether coronary intravascular lithotripsy (IVL) is non-inferior to rotational atherectomy (RA) regarding minimal stent area (MSA). METHODS The randomized, prospective non-inferiority ROTA.shock trial enrolled 70 patients between July 2019 and November 2021. Patients were randomly (1:1) assigned to undergo either IVL or RA before percutaneous coronary intervention of severely calcified coronary lesions. Optical coherence tomography was performed at the end of the procedure for primary endpoint analysis. RESULTS The primary endpoint MSA was lower but non-inferior after IVL (mean: 6.10 mm2 , 95% confidence interval [95% CI]: 5.32-6.87 mm2 ) versus RA (6.60 mm2 , 95% CI: 5.66-7.54 mm2 ; difference in MSA: -0.50 mm2 , 95% CI: -1.52-0.52 mm2 ; non-inferiority margin: -1.60 mm2 ). Stent expansion was similar (RA: 0.83 ± 0.10 vs. IVL: 0.82 ± 0.11; p = 0.79). There were no significant differences regarding contrast media consumption (RA: 183.1 ± 68.8 vs. IVL: 163.3 ± 55.0 mL; p = 0.47), radiation dose (RA: 7269 ± 11288 vs. IVL: 5010 ± 4140 cGy cm2 ; p = 0.68), and procedure time (RA: 79.5 ± 34.5 vs. IVL: 66.0 ± 19.4 min; p = 0.18). CONCLUSION IVL is non-inferior regarding MSA and results in a similar stent expansion in a random comparison with RA. Procedure time, contrast volume, and dose-area product do not differ significantly.

Abstract
Background and purpose Gliomas are the most common primary malignant central nervous system tumors in adults, exhibiting a poor prognosis. Indoleamine 2, 3-dioxygenase-1 (IDO-1) has important functions in cancer immunotherapy due to its role in escaping cancer cells from the immune system. In this study we purposed to evaluate the correlation between IDO-1 expression and clinicopathological parameters in gliomas, and whether IDO-1 can be a prognostic marker. . Methods n=75 patients in total, n=25 patients with low grade glial tumors (LGG, grade 1-2), n=25 patients with high grade glial tumors (HGG, grade 3-4), and n=25 persons with normal brain tissue as control group were included in this study. IDO-1 expression was categorized by using immunohistochemical staining in biopsy specimens as high (H) and low (L) groups among the patients with gliomas. We used a 95% percent confidence interval and p <0.05 to analyze the association between the degree of IDO-1 expression, clinicopathological characteristics, and survival rates in glioma patients. . Results In HGG, IDO-1 levels were higher than in control brain tissue and LGG (p< 0.001). The mean overall survival (OS) was longer in the L-IDO-1 group (64.53 ± 3.34) in months (95% CI: 57.969-71.098) compared to the H-IDO-1 group (43.74 ± 4.36) in months, (95% CI: 35.218-52.330) (p< 0.05). . Conclusion IDO-1 expression is an independent prognostic biomarker to predict OS and progression in HGG. IDO-1 can be evaluated as an alternative instrument for precision medicine in the treatment of gliomas. .

Abstract
AIM to investigate the changes in the biomarker levels related to inflammation and tissue destruction in the periapical exudate of mandibular premolar teeth with asymptomatic apical periodontitis after receiving intracanal cryotherapy, to compare cryotherapy and control groups in terms of analgesic intake, interappointment, and postoperative pain, and evaluate the correlation between biomarker levels and interappointment pain. METHODOLOGY Mandibular premolar teeth of 44 patients aged 18-35 years, diagnosed with asymptomatic apical periodontitis, were root canal treated in two visits (registered as NCT04798144). Baseline periapical exudate samples were obtained, and the patients were assigned to either control or intracanal cryotherapy group according to the final irrigation with distilled water either at room temperature or 2.5°C. The canals were dressed with calcium hydroxide. In the second visit, the calcium hydroxide was removed with passive ultrasonic irrigation, and the periapical exudate was sampled again. IL-1β, IL-2, IL-6, IL-8, TNF-α, PGE2 and MMP-8 levels were determined with ELISA. Postoperative pain levels were recorded for six days following both visits using a visual analogue scale. Data were analysed using t-test, Mann-Whitney U, and correlation tests. RESULTS There was a significant correlation between the pain scores reported after first visit and IL-1β and PGE2 levels (p < .05). IL-1β, IL-2, and IL-6 levels showed no significant difference in the cryotherapy group (p > .05), while they significantly increased in the control group (p < .05). There was a decrease in IL-8, TNF-α, PGE2 , and MMP-8 levels, however, the difference was not significant (p > .05). Pain scores were significantly lower in the cryotherapy group for the first three days (p < .05), except for 24th hours (p > .05). CONCLUSIONS The positive correlation between interappointment pain and IL-1β and PGE2 levels might indicate that these biomarker levels can be used to predict the severity of postoperative pain. Intracanal cryotherapy was effective in reducing postoperative pain in the short term in teeth with asymptomatic apical periodontitis. Cryotherapy prevented an increase in IL-1β, IL-2, and IL-6 levels compared to the control group.

Abstract
Background: Ribociclib, palbociclib and abemaciclib are currently approved CDK4/6 inhibitors along with aromatase inhibitors as the first-line standard-of-care for patients with hormone receptor-positive, HER2-negative metastatic breast cancer. Methods: The authors report retrospective real-life data for 600 patients with estrogen receptor- and/or progesterone receptor-positive and HER2-negative metastatic breast cancer who were treated with ribociclib and palbociclib in combination with letrozole. Results & conclusion: The results demonstrated that the combination of palbociclib or ribociclib with letrozole has similar progression-free survival and overall survival benefit in real life for the patient group with similar clinical features. Specifically, endocrine sensitivity may be a factor to be considered in the treatment preference.

Abstract
PURPOSE Extrapontine myelinolysis (EPM) is a highly uncommon, life-threatening disease, particularly in individuals who initially appear with severe clinical symptoms. Here, we describe a case of EPM caused by the rapid correction of hyponatremia that had severe clinical signs at first but parkinsonism symptoms were fully improved after treatment. CASE REPORT A 46-year-old female patient was admitted to the hospital due to impaired consciousness. Her medical history reveals that she has PAI, or primary adrenal insufficiency. Initial laboratory measurements showed that the serum's sodium (Na) concentration was 104 mEq/L, chloride (Cl) content was 70 mmol/L, potassium (K) content was 4.95 mEq/L, glucose was 42 mg/dL, hydrogen potential (Ph) was 7.12, and bicarbonate (HCO3) concentration was 10 mmol/l. The adrenocorticotropic hormone (ACTH) level was 21 mg/ml, while the cortisol level was 1.2ug/dl. Her mental state was unclear, she had sluggish hypophonic speech, generalized akinesia/rigidity in both upper and lower extremities, trouble swallowing solid and liquid meals, and sialorrhea were all discovered after the Na level was corrected. Hyperintense lesions were visible in the bilateral putamen and caudate nuclei of the Magnetic Resonance Imaging (MRI) T2 and flair-weighted scans, which indicate EPM. EPM was treated with corticosteroids and dopamine agonists, and she was eventually released after complete recovery. CONCLUSION Even if there are severe clinical symptoms at first, prompt diagnosis and treatment, such as dopaminergic, corticosteroid, and palliative therapy, can save a patient's life.

Abstract
Abstract
Background
The unfolded protein response of the endoplasmic reticulum (UPRER) is highly activated in cardiovascular diseases and aims to restore homeostasis by improving protein folding. An analogue cytoprotective mitochondrial unfolded protein response (UPRMito) regulated by an orthologue of the activating transcription factor 5 (ATF5) was described in model organism c. elegans. However, in humans it is not clear if there is a distinct UPRMito, and if there is an activation of an UPRMito during stress induced by cardiovascular diseases. The endothelium is subjected to high levels of mitochondrial stress, e.g. in atherosclerosis.
Purpose
To provide a systematic characterization of the UPRMito in human coronary artery endothelial cells (HCAEC).
Methods and results
HCAEC were treated with Nicotinamide Riboside (NR), a NAD+ precursor that activates UPRMito without inducing cellular stress. NR treatment did not induce toxicity and improved cell viability at a concentration of 100μM NR. Quantitative PCR confirmed a dose-dependent upregulation of UPRMito markers. Additionally, we measured expression of ATF4, which is discussed to regulate an integrated stress response in mammals by activating both the UPRMito and UPRER. ATF4 upregulation upon NR treatment was more pronounced than ATF5 upregulation. Analysis of GTEX-Data showed that ATF5 is almost exclusively expressed in liver tissue, while ATF4 shows ubiquitous expression. Among 54 tissues, aortic tissue and coronary arterial tissue are among the five tissues with the highest ATF4 expression.
Analysis of RNA-seq-data of human carotid atherosclerosis revealed that the two transcription factors are differentially regulated. ATF4 is downregulated in unstable plaque, while ATF5 is upregulated. Moreover, ATF4 is in both conditions highly more abundant than ATF5. Accordingly, endothelial cells incubated under atherosclerotic conditions (oxLDL + high glucose) exhibited a ATF4 down- and ATF5 upregulation. Genes previously described to be involved in the UPRMito exhibited a similar expression pattern as ATF4.
To further elucidate these findings, we will perform transcriptomic analyses of HCAEC treated with atherosclerotic stimuli (IL-1β, oxLDL), UPRER inductors (Thapsigargin, Tunicamycin) and stressors of mitochondrial proteostasis (Oligomycin, MitoBloCK-6), to analyze, if ATF5- or ATF4-related pathways are dysregulated. Specific inhibitors and UPRMito activators will be used to investigate the significance of ATF4 and ATF5 on endothelial cell function (proliferation, migration, apoptosis, monocyte adhesion).
Conclusion
The UPRMito is dysregulated during the pathogenesis of atherosclerosis in HCAEC. Further findings are required to elucidate, if the UPRMito is activated separately and specifically by ATF5 or as part of an integrated cellular stress response by ATF4. A deeper understanding of these stress responses is crucial for the identification of novel therapeutic targets in atherosclerosis.

Abstract
Abstract
Background
Endoplasmic-reticulum-stress (ER Stress) and associated chaperones like the main ER-Stress moderator GRP78 (glucose-regulated-protein, 78kDa) are involved in the pathogenesis of coronary artery disease (CAD). In addition to their intracellular localization and effects, secretion and extracellular properties of chaperones, including GRP78, were recently described. However, a diagnostic or prognostic relevance of serum ER-chaperones in patients with CAD has not been established yet.
Purpose
To investigate the significance of serum GRP78 in patients undergoing coronary angiography for suspected CAD.
Methods
Serum concentration of GRP78 was measured by ELISA in 789 patients with indication for coronary angiography (both ACS and CCS). CAD was defined as >50% stenosis in any major coronary artery. Clinical endpoint was one-year all-cause mortality.
Results
Mean age was 70.8±11.9 years and 65% of patients were male. 192 (24%) patients presented with acute coronary syndrome (ACS). CAD was found in 72.4% of patients. Mean GRP78 serum concentration was 2492 ng/ml. Increased levels of GRP78 (> median) were associated with diabetes (29.9% vs. 23.1%, p=0.03), a higher BMI (28.9±7.1 kg/m2 vs. 27.0±6.0 kg/m2, p<0.0001) and chronic kidney disease (CKD: 23.3% vs. 17.1%, p=0.03). There was no difference regarding age or sex.
GRP78 levels were increased in patients with CAD when compared to patients without CAD (2640 ng/ml [95% CI: 2415–2864] vs. 2178 ng/ml [95% CI: 1893–2463], p=0.013, Fig A). Interestingly, GRP78 levels were lower in patients with ACS than in patients with CCS (2284 ng/ml [95% CI: 1944–2642] vs. 2822 [95% CI: 2531–3113], p=0.018, Fig B). To further elucidate these findings, we analyzed available proteomics of patients with hypertrophic cardiomyopathy undergoing septal ablation as a model for a planned myocardial infarction (PMI)1. Coronary sinus blood samples drawn 10 and 60 min after PMI showed a downregulation of GRP78 levels compared to baseline.
Finally, we assessed prognostic relevance of GRP78 in patients with CAD. Increased GRP78 levels were associated with lower one-year mortality (5.3% vs. 10.6% vs. p=0.016). Increased GRP78 levels were associated with reduced one-year mortality in both continuous (HR: 0.48 [95% CI: 0.25–0.92]) and categorial analyses stratified by median GRP78. After adjusting for age, sex, BMI, diabetes, CKD and ACS, GRP78 remained an independent predictor of one-year mortality (HR: 0.51 [0.26–0.96], p=0.039).
Conclusion
GRP78 serum levels are generally elevated in patients with CAD but downregulated during ACS. Reduced levels are associated with increased one-year mortality. These results support previous findings that GRP78 secretion is a protective mechanism in cardiovascular diseases. Further mechanistic studies are warranted to foster our understanding of the effects of extracellular GRP78 and to aid in the identification of modifying therapeutic targets.

Abstract
Abstract
Introduction
Glucose-Regulated Protein 78kD (GRP78) is a chaperone and the main regulator of the ER-stress response. Upon ER Stress, GRP78 activates the unfolded protein response (UPR), which aims to clear unfolded proteins and restore ER homeostasis. A prolonged activation of the UPR triggers inflammation, thus contributing to the progression of cardiovascular diseases. Recently, extracellular secretion of GRP78 was described. However, the pathophysiological relevance of secreted GRP78 in atherosclerosis and endothelial cell inflammation remains to be elucidated.
Aim
Aim of this study is to investigate the role of GRP78 secretion in endothelial cells.
Methods and results
First, we sought to investigate if vascular cells secrete GRP78 during ER Stress. Human coronary artery endothelial cells (HCAEC) were treated with the ER stress inductor tunicamycin for up to 48h. After ER Stress induction, Western Blot and ELISA experiments detected an increased intracellular GRP78 expression. Intriguingly, prolonged ER Stress also promoted extracellular secretion of GRP78. Proteomic analysis confirmed that after ER-Stress induction, GRP78 is one of the most highly upregulated extracellular proteins (2.43-fold). Co-incubation with Brefeldin A, an inhibitor of ER-Golgi protein transport, abolished extracellular secretion (Fig.1). Hence, ER-Stress-induced GRP78 secretion is an actively regulated process.
Next, the effect of GRP78 containing conditioned medium (CM) on HCAEC was analyzed. Treatment with GRP78 containing CM decreased GRP78 mRNA expression in target cells (0.35-fold vs. control [+BFA], p<0.0001). Furthermore, it increased viability (93.0% vs. 79.6%, p=0.017) and decreased formation of reactive oxygen species (0.78-fold). Moreover, expression of markers of vascular inflammation and ER Stress (e.g., NF-κB and CHOP) was decreased when compared to control CM with additional BFA treatment.
However, ER Stress induced by tunicamycin exhibits deleterious effects on donor cells and is therefore not feasible for in vivo usage. Thus, we utilized Bip protein inducer x (Bix), a recently described small-molecule activator of GRP78. Treatment with Bix also promoted expression of GRP78 and general UPR activation (e.g., ATF4, XBP1). Moreover, in contrast to tunicamycin, Bix treatment did not impair viability of HCAEC.
After treatment with Bix-induced CM, apoptosis (0.77-fold vs. 1.64-fold, p<0.0001) and expression of markers of vascular inflammation (e.g., Il-6) were significantly decreased compared to control CM. Furthermore, presence of GRP78 was able to promote proliferation and viability.
Conclusion
Endothelial ER Stress promotes GRP78 secretion. Presence of GRP78 in conditioned medium ameliorates subsequent ER Stress and endothelial inflammation, which play a critical role in atherogenesis. Modification of GRP78 secretion by Bix might be a feasible and innovative therapeutic option for vascular inflammation and endothelial regeneration.

Abstract
Abstract
Background
Despite major advances, transcatheter aortic valve replacement (TAVR) is associated with procedure-related vascular and bleeding complications, that have a significant impact on mortality. A recently published study has shown that heparin antagonization using protamine resulted in significantly lower rates of serious bleeding events in patients undergoing TAVR as compared to those without heparin reversal. However, the optimal protamine-to-heparin dosing ratio to prevent bleeding complications without increasing ischemic complications in patients undergoing TAVR is unknown. Accordingly, daily clinical practice varies between selective to routine administration of protamine in different dosing ratios.
Purpose
The aim of this observational multicentre study was to compare the safety and efficacy of two different protamine-to-heparin dosing ratios for the prevention of bleeding complications after TAVR.
Methods
The study included 1446 patients undergoing TAVR, of whom 623 (43.1%) received partial and 823 (56.9%) full heparin antagonization (0.4–0.6 mg versus 0.9–1.0 mg protamine/100 units of heparin). The indication for partial or full heparin antagonization was left to the discretion of the operator, who made the decision according to the patient's individual thrombotic and bleeding risk. The primary endpoint was a composite of 30-day mortality, life-threatening and major bleeding. Safety endpoints included stroke and myocardial infarction at 30 days.
Results
The overall study population had a mean age of 81.1±6.0 years; 47.9% were of female gender.
The baseline characteristics were well balanced between the two groups. Full antagonization of heparin resulted in significantly lower rates of the primary endpoint as compared to partial heparin reversal (5.6 vs. 10.4%, p<0.01), mainly driven by lower rates of life-threatening (0.5 vs 1.6%, p=0.05) and major bleeding (3.2 vs 7.5%, p<0.01). The incidence of major vascular complications was significantly lower in patients with full heparin reversal (3.5 vs 7.5%, p<0.01), as presented in Figure 1. Accordingly, the post-interventional drop in hemoglobin level and the need for red-blood-cell transfusion was lower in patients receiving full as compared to partial heparin reversal (1.5±1.2 vs 1.7±1.2 g/dl, p<0.01; 10.4 vs 15.9%, p<0.01, respectively). Regarding safety endpoints, no differences were observed in the incidence of stroke and myocardial infarction between the groups (2.2 vs 2.6%, p=0.73 and 0.2 vs 0.4%, p=0.64, respectively). Multivariate regression analyses revealed that full antagonization of heparin (OR: 0.43 [95% CI: 0.24–0.81], p<0.01) was independently associated with the primary end point
Conclusion
Full heparin antagonization resulted in significantly lower rates of life-threatening and major bleeding after TAVR as compared to partial heparin reversal. The occurrence of stroke and myocardial infarction was low and comparable between both groups.

Abstract
INTRODUCTION Alectinib is an effective second-generation ALK tyrosine kinase inhibitor (TKI) used in the first-line treatment of patients with advanced ALK-positive NSCLC. Recent studies demonstrated that the percentage of ALK-positive tumor cells in patient groups receiving crizotinib might affect outcomes. This study aimed to investigate whether the percentage of ALK-positive cells had a predictive effect in patients with advanced NSCLC who received first-line Alectinib as ALK-TKI. MATERIALS AND METHODS This retrospective study included patients with advanced-stage NSCLC who received alectinib as a first-line ALK-TKI and whose percentage of ALK-positive cells was determined by FISH at 27 different centers. Patients who received any ALK-TKI before alectinib were not included in the study. Patients were separated into two groups according to the median (40%) value of the percentage of ALK-positive cells (high-positive group ≥ 40% and low-positive group < 40%). The primary endpoint was PFS, and the secondary endpoints were OS, ORR, and PFS of the subgroups based on different threshold values for the percentage of ALK-positive cells. RESULTS 211 patients were enrolled (48.3% female, 51.7% male) to study. 37% (n = 78) of the patients had received chemotherapy previously. After a median of 19.4 months of follow-up, the median PFS was not reached in the high-positive group (n = 113), but it was 10.8 months in the low-positive group (n = 98) (HR 0.39; 95% CI 0.25-0.60, p < 0.001). The median OS in the high-positive group was not reached, whereas it was 22.8 months in the low-positive group (HR 0.37; 95% CI 0.22-0.63, p < 0.001). ORR was significantly higher in the high-positive group (87.2 vs. 68.5%; p = 0.002). According to the cut-off values of < 20%, 20-39%, 40-59%, and ≥ 60%, the median PFS was 4.5, 17.1, and 26 months, respectively, and could not be reached in the ≥ 60% group. CONCLUSION Our study demonstrated that the efficacy of alectinib varies significantly across patient subgroups with different percentages of ALK-positive cells. If these findings are prospectively validated, the percentage of ALK-positive cells may be used as a stratification factor in randomized trials comparing different ALK-TKIs.

Abstract
BACKGROUND Perioperative FLOT regimen is a standard of care in locally advanced operable gastric and GEJ adenocarcinoma. We aimed to determine the efficacy, prognostic factors of perioperative FLOT chemotherapy in real-life gastric and GEJ tumors. METHODS The data of patients who were treated with perioperative FLOT chemotherapy were retrospectively analyzed from 34 different oncology centers in Turkey. Baseline clinical and demographic characteristics, pretreatment laboratory values, histological and molecular characteristics were recorded. RESULTS A total of 441 patients were included in the study. The median of age our study population was 60 years. The majority of patients with radiological staging were cT3-4N(+) (89.9%, n = 338). After median 13.5 months (IQR: 8.5-20.5) follow-up, the median overall survival was NR (95% CI, NR to NR), and median disease free survival was 22.9 (95% CI, 18.6 to 27.3) months. The estimated overall survival at 24 months was 62%. Complete pathological response (pCR) and near pCR was achieved in 23.8% of all patients. Patients with lower NLR or PLR have significantly longer median OS (p = 0.007 and p = 0.033, respectively), and patients with lower NLR have significantly longer median DFS (p = 0.039), but PLR level did not affect DFS (p = 0.062). The OS and DFS of patients with better ECOG performance scores and those who could receive FLOT as adjuvant chemotherapy instead of other regimens were found to be better. NLR was found to be independent prognostic factor for OS in the multivariant analysis. At least one adverse event reported in 57.6% of the patients and grade 3-4 toxicity was seen in 23.6% patients. DISCUSSION Real-life perioperative FLOT regimen in operable gastric and GEJ tumors showed similar oncologic outcomes compared to clinical trials. Better performance status, receiving adjuvant chemotherapy as same regimen, low grade and low NLR and PLR improved outcomes in real-life. However, in multivariate analysis, only NLR affected OS.

Abstract
Aims: In this multicenter study, the authors aimed to determine the real-life efficacy and safety of first-line alectinib. Materials & methods: This retrospective trial included advanced-stage, ALK-positive non-small-cell lung cancer patients who were treated with first-line alectinib in terms of ALK-tyrosine kinase inhibitors, regardless of previous chemotherapy. The co-primary end points were progression-free survival both for all patients and for the treatment-naive population. The secondary end points were overall response rate, overall survival, rate of CNS progression and safety. Results & conclusion: A total of 274 patients (n = 177 for treatment-naive patients) were enrolled in the study. The median progression-free survival was 26 and 28.8 months for all patients and the treatment-naive group, respectively. The overall response rate, CNS progression rate and 1-year overall survival ratio were 77.9, 12.4 and 77%. Alectinib is a highly effective therapy with a favorable safety profile.

Abstract
Neoadjuvant chemotherapy (NACT) in gastroesophageal junction (GEJ) and gastric cancer (GC) was shown to improve survival in recent studies. We aimed to share our real-life experience of patients who received NACT to compare the efficacy and toxicity profile of different chemotherapy regimens in our country. This retrospective multicentre study included locally advanced GC and GEJ cancer patients who received NACT between 2007 and 2021. Relation between CT regimens and pathological evaluation were analysed. A total of 794 patients from 45 oncology centers in Turkey were included. Median age at the time of diagnosis was 60 (range: 18-86). Most frequent NACT regimens used were FLOT (65.4%), DCF (17.4%) and ECF (8.1%), respectively. In the total study group, pathological complete remission (pCR) rate was 7.2%, R0 resection rate 86.4%, and D2 dissection rate was 66.8%. Rate of pCR and near-CR (24%), and R0 resection (84%) were numerically higher in FLOT arm (p > 0.05). Patients who received FLOT had also higher chemotherapy-related toxicity rate compared to patients who received other regimens (p > 0.05). Median follow-up time was 16 months (range: 1-154 months). Estimated median overall survival (OS) was 58.4months (95% CI: 35.2-85.7) and disease-free survival (DFS) was 50.7 months (95% CI: 25.4-75.9). The highest 3-year estimated OS rate was also shown in FLOT arm (68%). We still do not know which NACT regimen is the best choice for daily practice. Clinicians should tailor treatment regimens according to patients' multifactorial status and comorbidities for to obtain best outcomes. Longer follow-up period needs to validate our results.

Abstract
OBJECTIVE Gestational diabetes mellitus (GDM) is a type of diabetes that affects from 3.8% to 6.9% of pregnancies worldwide, causing significant mortality and unfavorable obstetric outcomes, such as delivery trauma and macrosomia risk. The fundamental processes of this metabolic disorder that first appeared during pregnancy are still unknown. Tissue hormones, particularly adipokines, have aided in understanding the pathophysiology of numerous disorders in recent years. This study aims to determine if Apelin-13 (APLN-13), Apelin-36 (APLN-36), Elabela (ELA), and nitric oxide (NO) molecules have all a part in the pathophysiology of GDM. PATIENTS AND METHODS The study included 30 pregnant control women and 30 pregnant women who had been diagnosed with GDM in the second trimester and whose body mass index and age were compatible with each other. Blood samples were collected from 60 participants during the second trimester (30 control pregnant women and 30 GDM pregnant women) and postpartum (17 controls vs. 14 GDM). In these blood samples, the amounts of APLN-13, APLN-36, ELA, and NO were studied using the ELISA method. In addition, the participants' glucose, lipid profiles, and other parameters were obtained from the hospital record files. At postpartum, 29 pregnant women (13 control and 16 pregnant women with GDM) dropped out of the study without explanation. RESULTS In the second trimester and postpartum plasma of mothers with GDM, APLN-13, APLN-36, NO, and ELA molecules were found to be significantly higher (< 0.05), compared to those of the control mothers, while APLN-13, APLN-36, NO values were significantly lower (0.05). While APLN-13, APLN-36, NO amounts in mothers with GDM were positively correlated with glucose amounts, they were negatively correlated with ELA amounts. Similarly, the triglyceride amounts in mothers with GDM were positively correlated with APLN-13, APLN-36 and NO, while they were negatively correlated with the ELA amounts. Due to gestational diabetes, APLN-13, APLN-36, NO, glucose, and triglyceride increased, and ELA decreased. CONCLUSIONS It is predicted that the glucose increase in GDM is because Apelins reduce glucose transport to erythrocytes by inhibiting the sodium-dependent glucose transporter (SGLT) and that the increase in triglyceride and NO may be associated with high glucose levels in GDM. As a result, we believe that the above-mentioned chemicals may cause GDM Pathology by triggering one another.

Abstract
OBJECTIVE Obesity is a serious public health problem associated with excessive food intake. Regulation of food intake in highly organized organisms is under the control of a large number of orexigenic and anorexigenic molecules. Therefore, the main purpose of this study has been to determine the relationship between obesity and some of the circulating orexigenic and anorexigenic peptides that have a role in appetite control and to determine whether the concentrations of these molecules differ according to blood groups. PATIENTS AND METHODS The study included 400 individuals of whom 100 were obese women, 100 obese men, 100 healthy men and 100 healthy women. Obese women and men were divided into 4 groups, according to their blood groups. In the control group, healthy women and healthy men were similarly divided into 4 blood groups. Each blood group within the groups, therefore, had 25 participants. RESULTS When leptin, nesfatin-1, obestatin and neuropeptide-Y, ghrelin and galanin levels of the control group and obese participants were compared, regardless of blood groups, leptin, nesfatin-1, obestatin and neuropeptide-Y were significantly higher, whereas only the ghrelin levels were significantly lower in obese patients. When the amounts of these hormones were measured according to gender, the situation was similar. When leptin, nesfatin-1, obestatin and neuropeptide-Y values of the control and obese participants' blood groups were compared with each other; these hormones were high in all blood groups; however, leptin levels in A blood group, nesfatin-1 levels in AB and O blood group, obestatin levels in AB blood group, neuropeptide-Y levels in A, B, AB blood groups were significantly higher. When the ghrelin levels of the blood groups in the control group and obese participants were compared, it was only significantly lower in the AB blood group. The ghrelin levels in the other blood groups of the obese individuals were again low, but not significantly so. When the distribution of hormones according to gender was evaluated, a situation parallel to the above results was recorded. CONCLUSIONS Leptin, nesfatin-1, obestatin and neuropeptide-Y and galanin levels of obese individuals were significantly higher than the control values, whereas the ghrelin values were significantly lower regardless of blood groups. Also, these hormones in blood partly varied with ABO blood groups. These different concentrations of hormones in ABO blood groups might be related with stimulation or suppression of appetite in human. However, further studies in other ethnic groups are needed to confirm these results.

Abstract
Aim: To compare the seropositivity rate of cancer patients with noncancer controls after inactive SARS-CoV-2 vaccination and evaluate the factors affecting seropositivity. Method: Spike IgG antibodies against SARS-CoV-2 were measured in blood samples of 776 cancer patients and 715 noncancer volunteers. An IgG level ≥50 AU/ml is accepted as seropositive. Results: The seropositivity rate was 85.2% in the patient group and 97.5% in the control group. The seropositivity rate and antibody levels were significantly lower in the patient group (p < 0.001). Age and chemotherapy were associated with lower seropositivity in cancer patients (p < 0.001). Conclusion: This study highlighted the efficacy and safety of the inactivated vaccine in cancer patients. Clinical Trials Registration: NCT04771559 (ClinicalTrials.gov).

Abstract
OBJECTIVE Metabolic syndrome (MetS) and obesity are important public health problems associated with adipose tissue mass. Asprosin, visfatin, and subfatin are new members of which fate in MetS and obesity has not been fully revealed yet. Thus, this study was to investigate the association between asprosin, visfatin, subfatin, and biochemical values, demographic data, and body composition measurement values in MetS patients with and without obesity. PATIENTS AND METHODS Blood samples were taken from a total of 90 people, including 31 MetS patients with obesity, 29 MetS patients without obesity, and 30 healthy (control). Asprosin, visfatin, and subfatin were studied by the ELISA method. RESULTS There was a negative correlation between asprosin and Body Mass Index (BMI) in the MetS + Obese group. The correlations between asprosin and urea and fasting insulin (FI) levels in the MetS group were positive and statistically significant (p < 0.05). While there was a statistically significant negative correlation (p < 0.05) between visfatin and BMI in the MetS + Obese group, the correlation with waist circumference in the MetS + Obese and MetS groups was statistically significant and negative (p < 0.05). There was a statistically significant negative relationship (p < 0.05) between aspartate aminotransferase value and visfatin. The results between visfatin values and asprosin and subfatin in all groups were significant (p < 0.05). CONCLUSIONS There is a direct relationship between circulating amounts of asprosin, visfatin, and subfatin hormones and age, weight, height, diastolic blood pressure, high-density lipoprotein-cholesterol, aspartate aminotransferase, alanine transaminase, and creatinine. Therefore, asprosin, visfatin, and subfatin hormones are the new biomarkers of metabolic turbulence.

Abstract
We analyzed the peripheral blood lymphocyte subsets of cancer patients infected with intestinal parasites, with an aim to find out the relationship between the levels of different types of lymphocytes with the prognosis of patients. 201 cancer patients aged 18 and over were included. Stool samples of the patients were examined using native-lugol, trichrome, modified trichrome (Weber's Trichrome stain), and modified Ziehl-Neelsen staining methods. Microsporidia and Cryptosporidium parvum were investigated at the genus and species levels using PCR. Lymphocyte subsets were determined by flow cytometry in blood samples. One or more parasite species were detected in 115 (56.7%) patients. The most common parasite species were Microsporidia, Blastocystis and Entamoeba coli, respectively. The frequency of parasites was high in patients with low lymphocyte percentage, CD3+ T cell and CD3+ CD4+ T (Th) cell levels in blood samples studied by flow cytometry. Microsporidia infection was significantly higher in patients with low lymphocyte percentage and Th cell levels. Similarly, C. parvum infection was found to be significantly higher in patients with low T lymphocyte percentage and Th cell level. Finally, Blastocystis infection was significantly higher in patients with low lymphocyte percentage and CD4/CD8 ratio higher than 1. The decrease in lymphocyte percentage, CD3+ T cell and Th cell count, and low CD4/CD8 ratio in cancer patients increase the frequency of intestinal parasitic infections. Based on these results, lymphocyte subsets may help identify cancer patients at high risk of opportunistic parasites. We suggest that opportunistic parasitic infections affecting the clinical course of the disease should be considered by clinicians during the follow-up and treatment of patients.

Abstract
BACKGROUND The COVID-19 pandemic is a unique challenge to the care of patients with hematological malignancies. We aim to provide supportive guidance to clinicians making individual patients decisions during the COVID-19 pandemic, in particular during periods that access to healthcare resources may be limited. DISCUSSION This review also provides recommendations, which are convenient in evaluating indications for therapy, reducing therapy-associated immunosuppression, and reducing healthcare utilization in patients with specific hematological malignancies in the COVID-19 era. Specific decisions regarding treatment of hematological malignancies will need to be individualized, based on disease risk, risk of immunosuppression, rates of community transmission of SARS-CoV-2, and available local healthcare resources.

Abstract
Abstract
Background
Vitamin K antagonists (VKA) like Warfarin are known to promote adverse cardiovascular remodelling. Contrarily, vitamin K supplementation has been discussed to decelerate cardiovascular disease. The recently described VKOR-isoenzyme Vitamin K epoxide reductase complex subunit 1-like 1 (VKORC1L1) is involved in vitamin K maintenance and exerts antioxidant properties. In this study, we sought to investigate the role of VKORC1L1 in neointima formation and on vascular smooth muscle cell (VSMC) function.
Methods and results
Treatment of wild-type mice with Warfarin increased maladaptive neointima formation after carotid artery injury. This was accompanied by reduced vascular mRNA expression of VKORC1L1.
In vitro, Warfarin was found to reduce VKORC1L1 mRNA expression in VSMC. VKORC1L1 downregulation by siRNA promoted viability, migration and formation of reactive oxygen species. VKORC1L1 knockdown further increased expression of key markers of vascular inflammation (NFκB, IL-6). Additionally, downregulation of the endoplasmic reticulum (ER) membrane resident VKORC1L1 increased expression of the main ER Stress moderator, glucose-regulated protein 78 kDa (GRP78). Moreover, treatment with the ER Stress inducer Tunicamycin promoted VKORC1L1, but not VKORC1 expression.
Finally, we sought to investigate, if treatment with vitamin K can mediate the protective properties of VKORC1L1. Thus, we examined effects of menaquinone-7 (MK7) on VSMC phenotype switch. MK7 treatment dose-dependently alleviated PDGF-induced proliferation and migration. In addition, we detected a reduction in expression of inflammatory and ER Stress markers.
Conclusion
VKA-induced neointima formation is associated with reduced vascular VKORC1L1 expression. VKORC1L1 inhibition contributes to an adverse VSMC phenotype while MK7 restores VSMC function. Thus, MK7 supplementation might be a feasible therapeutic option to modulate vitamin K- and VKORC1L1-mediated vasculoprotection.

Abstract
Abstract
Background
Intravascular coronary lithotripsy (IVL) is a novel alternative treatment for heavily calcified lesions. This study sought to determine the strategy success and safety of IVL on calcified lesions in an all-comers cohort of patients.
Methods
Patients with moderate and severely calcified coronary lesions were screened in two centers in Spain and Germany starting April 2018. Until February 2019, 61 patients with 67 lesions were eligible for IVL. Patients were assigned to the following groups: A) Primary IVL therapy for patients with circumferential calcified de-novo coronary lesions (n=32), B) Secondary IVL therapy for patients with moderate or severe calcified coronary lesions in which conventional non-compliant balloon dilatation failed (n=18) and C) Tertiary IVL therapy in patients with in-stent stenosis due to stent underexpansion after previous stenting (n=17). Primary endpoint was strategy success and safety outcome. Strategy success was defined as successful stent delivery and expansion with attainment of <20% in-stent residual stenosis of the target lesion. Safety outcome were procedural complication, defined as coronary dissection, slow or no-reflow phenomenon, new coronary thrombus formation during PCI, abrupt vessel closure and device failure (inability to place the balloon, malfunction, or burst) and in hospital MACE.
Results
61 patients with 67 calcified lesions were treated with IVL. Mean diameter of calcified stenosis on quantitative coronary angiography was 72.02±13.8% at baseline and decreased to 17.7±15.84% (p-value: <0.01) after IVL with an acute gain of 1.9±0.63 mm. Mean minimal lumen diameter was 1.0±0.5 mm at baseline and increased after IVL to 2.9±0.6 mm. The overall average of applied pulses was 63±22. The primary endpoint of strategy success was reached overall in 85.2% of patients. 4 type b dissections (3 in group A, 1 in group B) were observed without further sequelae. There were no in-hospital MACE. In one patient (1.6%) non-ischemia driven target lesion failure was observed in routine follow up coronary angiography and was in need for revascularization. According to the subgroups, strategy success in primary IVL treatment (group A) and secondary IVL treatment (group B) was reached in 81.3% and 83.3% of cases, respectively. In tertiary IVL therapy (group C), the primary study endpoint was reached in 64.7% of cases. Device delivery and IVL treatment of target lesion could be performed in all lesions without vessel complications. 7 IVL balloons ruptured during treatment without any sequelae. Rupture was observed in most cases after repositioning of the balloon within the calcified lesion.
Conclusions
IVL provides a valid strategy for lesion preparation in severely calcified coronary lesions, with high success rate, and low procedural complication and MACE rates. Longitudinal studies will confirm if these favourable initial results of IVL-supported PCI are followed by good long-term results.

Abstract
BACKGROUND Colorectal cancer (CRC) is a rare disease amongst children and adolescents. Previous studies have reported a number of differences between children/adolescents, young adults, and adult patients with CRC. However, none of these studies compared these age groups according to their clinicopathologic and prognostic characteristics. In the current study, we compare these three age groups. METHODS A total of 173 (1.1% of 15,654 patients) young CRC patients (≤25 years) were included in the study. As a control group, 237 adult CRC patients (>25 years) were also included. Patients were divided into three age groups: child/adolescent (10-19 years), young adult (20-25 years), and adult (>25 years). RESULTS Statistical differences amongst the three groups in terms of gender (p = 0.446), family history (p = 0.578), symptoms of presentation (p = 0.306), and interval between initiation of symptoms and diagnosis (p = 0.710) could not be demonstrated. Whilst abdominal pain (p < 0.001) and vomiting (p = 0.002) were less common in young adults than in other groups, rectal bleeding and changes in bowel habits were relatively less common in adolescents than in other groups. Rectal localisation (p = 0.035), mucinous adenocarcinoma (p < 0.001), and a poorly differentiated histologic subtype (p < 0.001) were less common in the adult group than in other groups. The percentage of patients with metastasis and sites of metastasis (e.g., peritoneum and lung) differed between groups. The median overall survival was 32.6 months in the adolescent group, 57.8 months in the young adult group and was not reached in the adult group (p = 0.022). The median event-free survival of the adolescent, young adult, and adult groups was 29.0, 29.9, and 61.6 months, respectively (p = 0.003). CONCLUSIONS CRC patients of different age groups present different clinicopathologic and prognostic characteristics. Clinicians should be aware of and manage the disease according to these differences.

Abstract
Despite significant advances in medicine, mortality due to cardiovascular disease is not yet preventable. We investigated the amounts of elabela (ELA) and apelin, synthesized by cardiomyocytes, and changes of these compounds in cardiac tissue and circulation after administration of iloprost (ILO) and sildenafil (SIL) in rats with induced myocardial ischemia (MI). We also investigated a connection with circulating troponin-I, creatine kinase (CK), creatine kinase-myocardial band (CK-MB) and nitric oxide (NO), and total anti-oxidant (TAS)/total oxidant status (TOS). We established eight study groups of five rats each. Group 1, sham, was given only physiologic serum; group 2, ILO; group 3, SIL; group 4, ILO + SIL; group 5, MI; group 6, MI + ILO; group 7, MI + SIL; group 8, MI + ILO + SIL. Troponin-I, CK, CK-MB and TAS-TOS were investigated using an autoanalyzer. NO, ELA and apelin were analyzed by ELISA. Tissue apelin and ELA expressions and localizations were determined by immunohistochemistry. The MI group compared to the control (sham) group showed that ELA, apelin, troponin-I, CK, CK-MB, NO and TOS levels were elevated significantly. Concentrations of these factors increased in MI, but decreased after ILO and SIL administration. The largest decrease of TOS was identified in the ILO + SIL group. ELA and apelin may be novel indicators of MI and administration of ILO and SIL, individually or together, may be useful for treating MI.

Abstract
Objective To determine the prognostic value of excision repairs cross-complementation group1 (ERCC1) gene in cases with nasopharyngeal carcinoma (NPC) treated with platinum-containing chemotherapy (PCT). Subjects and Methods The present study was included 33 cases in local advanced stage with NPC. ERCC1 expression was evaluated by using immunohistochemical staining in biopsy specimens. We evaluated the relationship between the degree of ERCC1 expression and clinicopathological features, response to therapy, survival rates in cases with NPC, retrospectively. Results ERCC1 expression was not observed in 5 (15.15%) of all cases. Thirteen (39.9%) cases weakly positive (+1, +2) and 15 (45.5%) cases of all them were rather strongly positive (+3). There was no statistically significant difference between the degree of ERCC1 expression and clinicopathological features, response to treatment, survival rates (P > 0.05) in cases with NPC. Conclusions ERCC1 expression has no predictive value for survival in cases locally advanced stage with NPC. Evaluation of ERCC1 expression is not appropriate with a biomarker to detect cases who can benefit from PCT in NPC.

Abstract
The actual role of splint therapy in preventing excessive loading of the temporomandibular joint (TMJ) is still debated. Lower intra-articular pressure levels have been measured in patients wearing occlusal splints, which may also reduce oxidative stress in the articular spaces. The aim of this study was to determine whether splint therapy reduces oxidative stress and inflammation in TMJ internal derangement patients by measuring interleukin 6 (IL-6), malondialdehyde (MDA), and 8-hydroxydeoxyguanosine (8-OHdG) levels in the synovial fluid (SF). Twenty-four patients with a temporomandibular disorder (TMD) were included in the study. TMJ SF samples were obtained prior to arthrocentesis. Twelve patients used a 2-mm hard acrylic, maxillary stabilization-type splint for 3 months after arthrocentesis. Twelve patients had no treatment after the SF aspiration. Second SF samples were obtained from all patients at 3 months post arthrocentesis. IL-6, MDA, and 8-OHdG levels in the samples were evaluated. All patients showed a significant symptomatic improvement after treatment (P < 0.005). No statistical correlation was found between the two groups concerning pre-treatment and 3-month SF levels of MDA, 8-OHdG, and IL-6. Although splint therapy was found to be successful in eliminating clinical symptoms of TMD, the results showed no beneficial effect on inflammation and oxidative stress markers in the synovial fluid.

Abstract
Isotretinoin can have significant adverse reactions on multiple systems. We report a unique case of pseudotumour cerebri and herpes encephalitis resulting due to isotretinoin. A 19-year-old female patient was admitted to our clinic, presenting with headache, nausea, vomiting and fever since three days. She had used isotretinoin for the last two months. The patient's neurological examination revealed the presence of neck stiffnes and a body temperature of 39,0◦C. MRI showed high signal localized to the temporal lobe and insula on the right and widened cerebrospinal fluid signal intensity on either side of the optic nerve. Electroencephalogram sharp and wave paroxysms on the right temporo-parietal region. Lumbar puncture showed an opening pressure of 320 mm H2O. The cerebrospinal fluid displayed the presence of 4-5 lymphocytes. On these grounds, the diagnosis of pseudotumour cerebri and herpes encephalitis was made. It is thus suggested that the physicians must keep in mind that pseudotumour cerebri and herpes encephalitis are possible adverse effects of isotretinoin.

Abstract
PURPOSE Solid pseudopapillary neoplasm (SPN) is a rare, low-grade neoplasm with excellent prognosis. In this study, we evaluated clinicopathological characteristics of patients diagnosed with SPN retrospectively. METHODS This is a retrospective study intended to characterize patients with the diagnosis of SPN between 2005 and 2015. Clinicopathological features, recurrence rate, and overall survival of 28 patients were recorded. Malignant SPN criteria were defined as the presence of distant metastasis (developed at diagnosis or during follow up) or lymph node involvement. RESULTS The mean age at diagnosis was 42 (range: 17-41). Among patients, 82% (n = 23) were female and 17.9% (n = 5) were male. The mean size of tumor was 5.81 cm (range: 2-15). The mean follow up period was 55.6 months, 1-year survival was 96.5% and 5-year survival rate was 88%. A total of 25 patients were alive at the end of follow-up period and 3 of the patients became exitus due to disease. Two patients had a metastatic presentation in livers at the diagnosis and metastasis developed in 3 patients during follow-up (liver of 1 patient, peritoneum in 1 patient and liver and peritoneum in 1 patient). The reason of admission was headache in 68% patients. The type of operation was frequently subtotal pancreatectomy (n = 11, 39.3%) and distal pancreatectomy (n = 10, 35.7%). Tumors were located frequently in body and tail regions (n = 18, 64.3%) and the number of patients with malignant criteria was 6 (21.4%). Although the mean age of malignant patients was significantly higher than benign patients (P = 0.046), there was no significant difference between 2 groups in terms of gender, tumor size, capsule invasion, perineural invasion, vascular invasion, and margin status. CONCLUSION SPN is a rarely seen tumor with low malignity potential. Surgical resection provides long-term survival rate even in local invasion or metastasis conditions.

Abstract
Objectives: To analyze the relationship between clinical features, hormonal receptor status, and survival in patients who were diagnosed with medullary breast cancer (MBC). Methods: Demographic characteristics, histopathological features, and survival statuses of 201 patients diagnosed with MBC between 1995 and 2015 were retrospectively recorded. Survival analyses were conducted with uni- and multivariate cox regression analysis. Results: Median follow-up time was 54 (4-272) months. Median patient age at the time of diagnosis was 47 years old (26-90). Of the patients, 91.5% were triple negative. Five-year recurrence free survival time (RFS) rate was 87.4% and overalll survival (OS) rate 95.7%. For RFS, progesterone receptor (PR) negativity, atypical histopathological evaluation, absence of lymphovascular invasion, smaller tumor, lower nodal involvement were found to be favourable prognostic factors by univariate analysis (p<0.05). The PR negativity and smaller tumor were found to be favourable factors by univariate analysis (p<0.05). However, none of these factors were determined as significant independent prognostic factors for OS (p>0.05). Conclusion: Turkish MBC patients exhibited good prognosis, which was comparable with survival outcomes achieved in the literature. The PR negativity was related to a better RFS and OS rates.

Abstract
Neuro-Behçet's disease (NBD) is a rare clinical entity that frequently presents neuro-psychiatric symptoms, and mesodiencephalic and pontobulbar lesions. There is only one published report about osteonecrosis in NBD. We report a patient whose first presentation was neurological NBD with presenting bilateral femoral heads osteonecrosis. A 36-year-old male was hospitalized with gait disorder, diplopia and speech disorder. The past medical history of the patient was unremarkable. The MR image showed mesencephalic lesion with oedemaas a hyperintense area. The present case was diagnosed as NBD and treated with methylprednisolone (1g /day) only for five days. One year after, bilateral hip pain developed. MR image of both hips showed well-demarcated areas of osteonecrosis in the bilateral femoral heads. The patient was operated by an orthopedic surgeon. Because early diagnosis and immediate treatment of osteonecrosis is very important, the physician must bear in mind that osteonecrosis might result from impaired microvascular involvement in even NBD.

Abstract
Objective: Several pathways are known to be activated during metastasis and treatment of cancer. We investigated the role of osteopontin (OPN) and stathmin-1 (STHMN1) in metastatic castrate-resistant (mCRPC). Methods: We included 30 patients who received at least 6 cycles of taxane regimen for metastatic mPC in the present study. For this study retrospective data was taken from Firat University, Faculty of Medicine, Medical Oncology Department between 2009 and 2015. OPN expression and STHMN1 expression were retrospectively evaluated by immunohistochemical staining in biopsy specimens. The relationship between the expression levels of OPN and STMN1 and the response to taxane based regimen and survival was analyzed. Results: There was mild or strong overexpression of OPN and STHMN1 in all the patients. STHMN1 expression was mildly positive (+2) in four of the cases (13.2%) while it was strongly positive (+3) in 25 (83.4%) cases. Similarly, OPN expression was mildly positive (+2) and strongly positive (+3) in five (16.6%) and 25 (87.4%) patients, respectively. There was no significant correlation between the expression levels of STHMN1 and OPN, survival, and response to taxane based regimen (p>0.05); however, OPN overexpression showed a significant correlation with lower Gleason scores (GS) (p:0.032). Conclusions: STHMN1 and OPN may be prognostic markers although they are not predictive markers of response to treatment in mCRPC. The overexpression of OPN may help identifying patients with lower GS.

Abstract
Hepatocellular cancer is one of the most common and fatal cancer tumor worldwide. However, the obtained results are questionable in terms of medical treatment of hepatocellular cancer. The muscle, soft tissue and cutaneous metastases of hepatocellular cancer, for instance, are rare and may result from interventional procedures. Seeding of tumor along the biopsy needle upon percutaneous biopsy is a very rare phenomenon. We report a very rare case of a 79 -year- old man, known to be hepatitis C virus carrier with a metastatic tumor in abdominal wall caused by seeding of tumor after three years following a percutaneous biopsy procedure. Even years later, after a biopsy procedure for diagnostic purposes and may be soft tissue metastases. This complication is a very rare condition that should not be ignored but can be observed. The biopsy requirement should be questioned closely and avoided unnecessary biopsy procedures.
