The Effect of Mother's Voice and Father's Voice Listened by Newborns During Heel Blood Collection on Pain Level and Physiological Parameters: A Randomized Controlled Study.

BACKGROUND: The newborn can learn the voices of its mother and father during intrauterine life, and the reencounter with these familiar voices after birth has a relaxing and calming effect on the baby. PURPOSE: The purpose of this study was to determine the effect of mother's voice and father's voice that newborns listened to during the heel blood collection procedure on pain level and physiological parameters. METHODS: The study was a randomized controlled trial. The study consisted of a total of 90 newborns as participants (mother voice group = 30, father voice group = 30, and control group = 30) at the Düzce Atatürk State Hospital Gynecology Service, Türkiye. Newborns randomly assigned to the intervention groups were made to listen to the mother's voice/father's voice during the heel prick procedure. The newborn in the control group received standard heel blood collection procedures. RESULTS: When the pain level of newborns was examined, it was determined that the lowest Newborn Infant Pain Scale score was in the mother's voice group (P < .05). When the physiological parameter results were evaluated, it was determined that the highest oxygen saturation value and the lowest heart rate were found in the mother's voice group (P < .05). CONCLUSION: It was determined that the mother's voice was the most effective method in relieving the pain that occurred during the heel prick procedure and in the positive course of physiological parameters in newborns. According to the results of the study, it is recommended to use the mother's voice in order to reduce the pain caused by the heel prick attempt in newborns and to regulate their physiological parameters.

High grade tumor budding is associated with poor survival in pathologic stage I lung adenocarcinoma.

AIM: Tumor budding is a significant prognostic parameter that has been related to aggressive behavior in early-stage tumors of various origins. The aim of this study was to evaluate the clinicopathological significance of tumor budding in pathologic stage (pStage) I lung adenocarcinomas. METHODS: This study comprised 107 patients who underwent curative resection for pStage I lung adenocarcinomas at our hospital between December 2010 and January 2016. We examined tumor budding on routine hematoxylin and eosin (H&E) slides from resected specimens. Tumors were categorized into two groups based on the degree of tumor budding: low grade (grade 0-1) and high grade (grade 2-3). We evaluated the relationship between tumor budding and overall survival (OS), disease-free survival (DFS) and clinicopathological parameters. RESULTS: There is a significant difference (p = 0.002) between the 5-year DFS rates of the high-grade and the low-grade tumor budding group, which were 70 % and 90 %, respectively. High-grade tumor budding positive patients from the same pathological stage (p < 0.001; HR = 2.93 [1.51-5.68]) and clinical stage (p = 0.002) had poorer cumulative survival rates than low grade tumor budding positive patients. High grade tumor budding was positively associated with spread through air spaces (STAS) (p < 0 0.001), lymphovascular invasion (LVI) (p < 0.001), tumor necrosis (p < 0.001), high SUVmax value (SUVmax>3.0) (p < 0.001), and tumor size >20 mm (p = 0.024). High-grade tumor budding was significant prognostic factor of OS (p < 0.006) and DFS (p < 0.001) on univariate Cox regression hazard model analysis. However, it did not show significance in the multivariate analysis (p > 0.05). CONCLUSIONS: High-grade tumor budding is an independent prognostic factor and associated with adverse clinicopathological features and poor survival rates. We proposed that high-grade tumor budding should be recognized as a new prognostic parameter and will be beneficial in predicting the clinical course in pStage I lung adenocarcinomas.

Comparison of the soft and hard tissue effects of two different protraction mechanisms in class III patients: a randomized clinical trial.

OBJECTIVE: The objective of the present study is to test the null hypotheses that there were no significant differences for hard and soft tissue changes induced by mini maxillary protractor (MMP) and face mask and rapid maxillary expansion (FM/RME). MATERIALS AND METHODS: Thirty-two patients who met the criteria were randomly divided into two groups: 16 patients (males/females 7/9) in the MMP group and 16 patients (males/females 6/10) in the FM/RME group. The patients in both groups were instructed to wear the appliances for at least 20 h per day until a 2-mm positive overjet was achieved. Hard and soft tissue profile changes observed by MMP and FM/RME were compared using paired and Student's t tests. RESULTS: Class III malocclusion and negative overjet were improved by means of skeletal changes in conjunction with upper incisor proclination and lower incisor retroclination in both groups. Maxilla and surrounding soft tissues (SNA, Ls-E, and Ls-PMV) were significantly moved anteriorly with less rotation of the palatal plane in the MMP group. Mandibular incisors were found to be more retrusive in the FM/RME group (p = 0.024). CONCLUSION: Both groups showed similar effects except more anterior movement of the maxilla and surrounding soft tissues with less rotation of the palatal plane and retrusion of lower incisors in the MMP group. CLINICAL RELEVANCE: This is the first study to compare the soft and hard tissue changes induced by MMP appliance with a conventional FM /RME.

The diagnostic importance of matrix metalloproteinase-7 and nestin in gastrointestinal stromal tumors.

BACKGROUND: The importance of the matrix metalloproteinase-7 (MMP-7) and nestin immunomarkers, C-kit proto-oncogene (CD117), and the efficiency of the Ki-67 proliferation index for gastrointestinal stromal tumors were evaluated. MATERIAL AND METHODS: This study was conducted by examining the microscope slides of 72 patients with gastrointestinal stromal tumors that were sent to the pathology laboratory between 2007 and 2012. Immunohistochemical staining for CD117, MMP-7, nestin, and marker of proliferation Ki-67 was performed. The correlations between the positive results for Ki-67, CD117, MMP-7, and nestin were evaluated relative to the tumor characteristics of size, localization, grade, cellular type, cellularity, cytology type, growth pattern, ulceration, necrosis, hemorrhage, invasion depth, and lymph node metastasis. RESULTS: The tumor was localized in the stomach in 42 of the patients, the intestines in 19, the colon in 7, and the rectum in 4. Comparisons among the groups showed that MMP-7 was correlated with the tumor grade (p<0.001), cellularity (p<0.009), cytologic atypia (p<0.001), ulceration (p=0.002), necrosis (p<0.001), and tumor size (p=0.001). Nestin was correlated with the tumor grade (p=0.013), and tumor size (p=0.024). Correlations among CD117, MMP-7, nestin, and Ki-67 were examined. Nestin and Ki-67 were both significantly correlated with CD117 and MMP-7 [(r=0.279, p=0.018), (r=0.322, p=0.006), (r=0.386, p=0.001), (r=0.386, p=0.002)], respectively. CONCLUSIONS: MMP-7 and nestin may be beneficial as markers, given their sensitivity to gastrointestinal stromal tumors.

Thymoquinone Inhibits Proliferation and Migration of MDA-MB-231 Triple Negative Breast Cancer Cells by Suppressing Autophagy, Beclin-1 and LC3.

BACKGROUND: Triple Negative Breast Cancer (TNBC) is an aggressive and highly heterogeneous subtype of breast cancer associated with poor prognosis. A better understanding of the biology of this complex cancer is needed to develop novel therapeutic strategies for the improvement of patient survival. We have previously demonstrated that Thymoquinone (TQ), the major phenolic compound found in Nigella sativa, induces anti-proliferative and anti-metastatic effects and inhibits in vivo tumor growth in orthotopic TNBC models in mice. Also, we have previously shown that Beclin-1 and LC3 autophagy genes contributes to TNBC cell proliferation, migration and invasion, suggesting that Beclin-1 and LC3 genes provide proto-oncogenic effects in TNBC. However, the role of Beclin-1 and LC3 in mediating TQ-induced anti-tumor effects in TNBC is not known. OBJECTIVE: To investigate the effects of TQ on the major autophagy mediators, Beclin-1 and LC3 expression, as well as autophagic activity in TNBC cells. METHODS: Cell proliferation, colony formation, migration and autophagy activity were evaluated using MTS cell viability, colony formation assay, wound healing and acridine orange staining assays, respectively. Western blotting and RT-PCR assays were used to investigate LC3 and Beclin-1 protein and gene expressions, respectively, in MDA-MB-231 TNBC cells in response to TQ treatments. RESULTS: TQ treatment significantly inhibited cell proliferation, colony formation, migration and autophagic activity of MDA-MB-231 cells and suppressed LC3 and Beclin-1 expressions. Furthermore, TQ treatment led to the inhibition of Integrin-ß1, VEGF, MMP-2 and MMP-9 in TNBC cells. CONCLUSION: TQ inhibits autophagic activity and expression of Beclin-1 and LC3 in TNBC cells and suppresses pathways related to cell migration/invasion and angiogenesis, including Integrin-ß1, VEGF, MMP-2 and MMP- 9, suggesting that TQ may be used to control autophagic activity and oncogenic signaling in TNBC.

Atypical lipomatous tumor in the submental region.

A 54-year-old male patient presented to our outpatient clinic complaining of a mass under his chin, which appeared nearly 1 year earlier. Pathologic diagnosis was atypical lipomatous tumor. To the best of our knowledge, this is the first reported case to localize subcutaneously in the head and neck region. Atypical lipomatous tumors/well-differentiated liposarcomas are rarely reported in the head and neck. We review the clinical and management features of atypical lipomatous tumors.

Increased micronucleus count predicts malignant behavior in pleural effusion fluid

Background/aim: Micronucleus (MN) frequency is used as a biomarker of chromosomal damage, genome instability, and cancer risk. The aim of this study was to evaluate the diagnostic usefulness of MN frequency to differentiate between malignant and benign pleural effusion samples. Materials and methods: Retrospectively, 78 pleural fluid cytology samples (including 20 cases of benign reactive mesothelial cells, 22 cases of suspicious cytology, and 36 cases of malignant cytology) were examined. The number of micronucleated cells in 1000 well- preserved cells was counted. Statistical tests were performed to compare the study groups. Recover operating characteristics (ROC) curve analysis was performed to suggest a cut-off value for predicting malignant behavior. Results: We evaluated a total of 78 cases of pleural effusion cytology. The number of micronucleated cells was significantly higher in cases with malignant outcome compared to cases with benign outcome. We observed that malignant samples had more micronucleated cells than suspicious ones, and suspicious cases had more micronucleated cells than reactive ones. There was a significant difference among all study groups. In addition, the frequency of MN-containing cells in suspicious cases correlates well with their outcomes. Conclusion: The results of this study reveal that there is an absolute, consistent, and proportional relationship between MN counts and malignancy in cytological samples of pleural effusions. MN scoring may be a helpful diagnostic tool for distinguishing malignant effusions from benign ones, and may be used as an adjunct tool to predict malignant behavior in challenging cases.

Cervical sympathetic chain schwannoma: two different clinical presentations.

In this report we present 2 cervical sympathetic chain schwannoma (CSCS) cases with different clinical presentations, one being a pulsatile neck mass associated with Horner's syndrome and the other being an asymptomatic neck mass. CSCS usually presents as an asymptomatic neck mass and atypical findings such as Horner's syndrome and/or pulsation may occur in rare cases. Pulsatile CSCSs are generally diagnosed as carotid body tumors at initial workup and patients are referred to vascular surgeons. The differences in symptomatology, the preoperative management, and the importance of differential diagnosis are discussed.

Prognostic Value of Cancer Stem Cell Markers CD44 and ALDH1/2 in Gastric Cancer Cases

Purpose: To determine expression levels of CD44 and ALDH1/2, known cancer stem cell (CSC) markers, in stomach adenocarcinomas and assess relationships with clinicopathologic parameters and prognosis. Methods: Eighty patients diagnosed with gastric cancer between the years 2011-2015 were included in this study of clinicopathologic characteristics, postoperative prognostic indexes and stem cell marker CD44 and ALDH1/2 expression in paraffin-embedded tumour sections analyzed immunohistochemically. Clinicopathologic parameters were evaluated using the chi-square test and t-test. Survival analyses were conducted using Kaplan-Meier statistics. Results: We observed positive CD44 and ALDH1/2 staining in 45.0 % and 67.5% of tumour tissues, respectively, but not in normal gastric mucosa. Recurrence-free survival (RFS) was found to be shorter in cases with high levels of CD44 expression (p=0.004). Similarly, short RFS was observed in patients with high levels of CD44 and ALDH1/2 co-expression (p=0.004). Furthermore, tumour invasion depth was found to correlate with high CD44 and ALDH1/2 co-expression (p=0.028). Conclusion: The cancer stem cell markers CD44 and ALDH1/2 may indicate poor patient prognosis and play a role in tumour development and invasion.

Micronuclei and nuclear buds: Highlighting overlooked indicators of chromosomal damage in thyroid aspiration smears.

BACKGROUND: We aimed to examine the diagnostic utility of micronuclei (MN) and nuclear buds (NBs) in aspiration smears of the well-differentiated epithelial lesions of thyroid. METHODS: One hundred five cases composed of 34 follicular nodular disease (FND), 31 Hashimoto's thyroiditis (HT), and 40 papillary thyroid carcinoma (PTC) were compiled retrospectively. May- Grünwald Giemsa (MGG) stained smears of each case were selected to count cells with nuclear protrusions (NPs) per 1000 cells. The frequency of cells with NPs (MN&NBs) was compared by using Mann-Whitney U test and Kruskal-Wallis tests when appropriate. Post-Hoc Tukey test was used for pairwise comparison of different diagnostic categories. By running a ROC curve analysis, diagnostic usefulness of the frequency of cells with NPs (MN&NBs) and their cut-off values to predict malignant behavior were calculated. P < 0.05 was regarded as significant. RESULTS: NPs (MN&NBs) were significantly more frequent in malignant cases than benign ones. NBs were more frequent in conventional PTC compared to FV of PTC, but the frequency of MN did not significantly differ between these. ROC curve analysis revealed that evaluation of the frequency of cells with NPs (MN&NBs) was a highly specific, sensitive, and diagnostically useful method to identify malignant behavior. CONCLUSION: To the best of our knowledge, this is the first study in the literature to evaluate the frequency of cells with NPs (MN&NBs) in human thyroid aspiration smears. Our results show that evaluation of NPs (MN&NBs) may be a useful diagnostic tool to detect PTC in thyroid aspiration smears. Diagn. Cytopathol. 2017;45:673-680. © 2017 Wiley Periodicals, Inc.
