Abstract
The ability to understand whether embryos survive the thaw process is crucial to transferring competent embryos that can lead to pregnancy. The objective of this study was to develop a proof of concept deep learning model capable of assisting embryologist assessment of survival of thawed blastocysts prior to embryo transfer. A deep learning model was developed using 652 labeled time-lapse videos of freeze-thaw blastocysts. The model was evaluated against and along embryologists on a test set of 99 freeze-thaw blastocysts, using images obtained at 0.5 h increments from 0 to 3 h post-thaw. The model achieved AUCs of 0.869 (95% CI 0.789, 0.934) and 0.807 (95% CI 0.717, 0.886) and the embryologists achieved average AUCs of 0.829 (95% CI 0.747, 0.896) and 0.850 (95% CI 0.773, 0.908) at 2 h and 3 h, respectively. Combining embryologist predictions with model predictions resulted in a significant increase in AUC of 0.051 (95% CI 0.021, 0.083) at 2 h, and an equivalent increase in AUC of 0.010 (95% CI -0.018, 0.037) at 3 h. This study suggests that a deep learning model can predict in vitro blastocyst survival after thaw in aneuploid embryos. After correlation with clinical outcomes of transferred embryos, this model may help embryologists ascertain which embryos may have failed to survive the thaw process and increase the likelihood of pregnancy by preventing the transfer of non-viable embryos.

Abstract
Background Assessment of nutritional status is gaining more importance in cancer patients because nutritional status is associated with response to chemotherapy, side effects of cancer treatment and disease progression. Several studies that were performed on patients with solid malignancies have shown the clinical significance of CONUT score (Controlling nutritional status). Aims Therefore we tried to show the utility of CONUT score in newly diagnosed Diffuse Large B Cell Lymphoma (DLBCL) patients which is the most frequently seen B Cell Lymphoma type. Methods Data of the 81 patients diagnosed with DLBCL were retrospectively evaluated. The primary endpoint of our study was to evaluate and classify newly diagnosed DLBCL patients according to the CONUT score and secondary endpoint was to show any relationship with CONUT score and overall survival. Patients' demographics, treatment details, stages, extranodal involvements, the presence of bulky disease, response to treatment options and overall survivals were evaluated from medical recordings. Results Univariate cox regression analysis CONUT score was associated with overall survival (HR: 2.34-95% CI: 1.55-3.24 P = 0.040). On multivariate Cox regression analysis model CONUT score ≥5 was found to be an independent prognostic factor for overall survival (HR: 4.96-95% CI: 1.77-13.97- P = 0.002). Conclusion The value of obtaining nutritional status in cancer patients is underestimated and CONUT score is simple, easily applicable and in our opinion is going to fill the gap especially in DLBCL patients.

Abstract
Abstract
Background: Oncology professionals face challenges to find out a complete solution in prevention or alleviation of chemotherapy induced peripheral neuropathy (CIPN). Current pharmacological treatments used for CIPN have limited effects and pose major side effects. At this point, management of CIPN by a multidisciplinary team approach is very crucial. Therefore, this randomized controlled study aimed to examine the effect of classical massage on CIPN using objective and subjective measurements in breast cancer patients receiving adjuvant paclitaxel.
Method:The study was conducted at Dr. Abdurrahman Yurtaslan Ankara Training and Research Hospital in Turkey between July 2017 and June 2018. The study was approved by a local ethical committee. Eligible patients with breast cancer included those who (a) were 18 years and older; (b) had no documented diagnosis of CIPN; (c) had receiving the first cycle of adjuvant paclitaxel. Exclusion criteria were (a) history of severe psychiatric disorder; (b) history of peripheral neuropathy due to any cause; (c) had lesion on hands or feet; (d) had bleeding or coagulation disorders. Simple randomization method was utilized to allocate patients to an intervention group (n=18) and a control group (n=19). Patients in the intervention group (IG) received totally 12 sessions classical massage, on the days of chemotherapy cycles. The duration of each massage was 30 min, with 20 min for the feet and 10 min for the hands. The CG received only routine care. After completion of paclitaxel regimen no intervention was applied to neither the IG nor the CG, and patients were followed at week 16. Subjective measurement tools included the Self-Leeds Assessment of Neuropathic Symptoms and Sign (S-LANSS); and the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy (EORTC QLQ-CIPN20). Electromyography (EMG) was applied as an objective measurement at baseline and week 12 for all patients by the same neurologist. The data were collected at five time points including baseline (T1), week 4 (T2) week 8 (T3), week 12 (T4) and week 16 (T5). To analyze data repeated measures ANOVA and Mann Whitney U tests were used.
Results: The S-LANSS scores were significantly lower in the IG when compared the CG (p<.05). Motor sub-dimension scores of EORTC QLQ-CIPN20 were significantly lower in favor of the IG compared to the CG. As for sensorial and autonomic sub-dimensions of the EORTC QLQ CIPN20 showed no significant difference. Regarding EMG outcomes, compound muscle action potentials of ulnar nerve and posterior tibial nerve in the IG were significantly higher than the CG at week 12.
Conclusion: In this study, classical massage initiated concurrently with adjuvant paclitaxel regimen decreased neuropathic pain severity and prevented motor axonal neuropathy in the IG when compared to the CG. Accordingly, classical massage had promising effects on prevention and alleviation of CIPN. Based on the results, classical massage can be recommended as a preventive complementary option for breast cancer patients receiving adjuvant paclitaxel.

Abstract
PURPOSE In this study, we aimed to describe the real-life practice outcomes of pertuzumab-trastuzumab-taxane (PTT) combination in visceral organ metastatic, trastuzumab-naive breast cancer (BC) patients. METHODS This study was conducted by Turkish Oncology Group and included 317 patients' data from 36 centers. RESULTS Median age was 51 (22-82). Median PFS was 28.5 months, while median OS was 40.3 months. Patients with brain metastases (n: 13, 4.1%) had worse PFS (16.8 m vs. 28.5 m; p = 0.002) and OS (26.7 m vs. 40.3 m; p = 0.009). Patients older than 65 years of age (n: 42, 13.2%) had significantly lower OS results (19.8 m vs. 40.3 m; p = 0.01). Two hundred sixty-eight patients (86.7%) received docetaxel while 37 patients (11.7%) received paclitaxel. PFS and OS were similar between taxane groups. In eight patients (2.5%), 5-40% ejection fraction decrement from baseline was detected without any clinical sign of heart failure. CONCLUSIONS Our RLP trial included only visceral metastatic, trastuzumab-naïve BC patients including cases with brain involvement who received PTT combination in the first-line treatment. Regardless of negative prognostic characteristics, our results are in parallel with pivotal trial. Further strategies for brain metastasis should be developed to improve outcomes despite encouraging results with PTT treatment. Taxane selection can be personalized and endocrine maintenance may further improve outcomes after taxanes were discontinued. To our knowledge, this is the largest scale real-life clinical practice study of pertuzumab-trastuzumab-taxane therapy to date.

Abstract
Dual-purpose management of winter cereals for grazing and grain production provides highly nutritive forage for ruminants in the spring and may positively affect straw feeding value. A 2-yr study investigated the effect of spring defoliation of triticale, wheat, and rye at the tillering and stem elongation stages on total biomass, grain yields, and straw quality. Furthermore, straws of spring-defoliated and undefoliated (control) cereal crops were evaluated for nutritional value and voluntary intake as a means of assessing the efficiency of dual-purpose management systems from the winter feeding context as well. The feeding study consisted of 9 total mixed rations (TMR), each containing 35% triticale, rye, or wheat straw obtained under 3 spring-defoliation regimens. The TMR were individually fed to fifty-four 1-yr-old Anatolian Merino ewes for 28 d. Defoliation of the crops at tillering did not affect the total biomass production or grain yields. However, biomass and grain yields were reduced ( < 0.01) by 55 and 52%, respectively, in crops defoliated at stem elongation. Straw of spring-defoliated cereals had less NDF and ADF concentrations ( < 0.01) but greater CP ( < 0.01), nonfiber carbohydrates ( < 0.01), and ME concentrations ( < 0.01) compared with straw from undefoliated crops. The increase in the nutritive value of straw led to greater nutrient digestion ( < 0.01) and intake of DM and OM of ewes ( < 0.01). However, sheep live weight gain did not differ among treatments ( > 0.77). This study indicated that straw feeding value and digestibility can be increased through spring defoliation.

Square prism micropillars improve osteogenicity of poly(methyl methacrylate) surfaces. JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2018; 29:53.

Abstract
Osteogenicity and osteointegration of materials is one of the key elements of the success of bone implants. Poly(methyl methacrylate) (PMMA) is the basic compound of bone cement and has been widely investigated for other orthopedic applications, but its poor osteointegration and the subsequent loosening of implant material limits its widespread use as bone implants. Micropillar features on substrate surfaces were recently reported to modulate cell behavior through alteration of cell morphology and promotion of osteogenesis. Utilization of this pillar-decorated topography may be an effective approach to enhance osteogenicity of polymeric surfaces. The aim of this study was to investigate the effect of cell morphology on the micropillar features on attachment, proliferation, and osteogenic activity of human osteoblast-like cells. A series of solvent cast PMMA films decorated with 8 µm high square prism micropillars with pillar width and interpillar distances of 4, 8 and 16 µm were prepared from photolithographic templates, and primary human osteoblast-like cells (hOB) isolated from bone fragments were cultured on them. Micropillars increased cell attachment and early proliferation rate compared to unpatterned surfaces, and triggered distinct morphological changes in cell body and nucleus. Surfaces with pillar dimensions and gap width of 4 µm presented the best osteogenic activity. Expression of osteogenic marker genes was upregulated by micropillars, and cells formed bone nodule-like aggregates rich in bone matrix proteins and calcium phosphate. These results indicated that micropillar features enhance osteogenic activity on PMMA films, possibly by triggering morphological changes that promote the osteogenic phenotype of the cells.

Abstract
<p><strong>Abstract.</strong> The aim of this study was to evaluate the effects of premating ewe weight and age on ewe reproductive performance, lamb growth and survival in Central Anatolian Merino (CAM) sheep. <br><br> The trial included 4935 ewes and 5548 lambs from 23 breeder flocks in Eskişehir Province. The live weights (LWs) and ages of the ewes were recorded 1 week before the mating season. The number of lambs born, fertility rate, multiple birth rate (MBR), and lamb survival rate (SR) at days 75 and 120 were determined. The effects of the LW and age of the ewe were found to be important for the reproductive performance of ewes and for the lamb's growth rate (<i>P</i> < 0.05–0.001). Ewe MBRs and the birth weight (BW) and LW of the lambs at days 75 and 120 increased proportionally with the increase in LW in ewes prior to mating. The fertility rate and MBR were lower (<i>P</i> < 0.05–0.001) in 1.5-year-old ewes than in older ewes. However, lambs' SR at days 75 and 120 were not affected by the premating LW and age of the ewe. In summary, a better reproductive performance and lamb growth rate in CAM flocks may be achieved by the selection of breeding ewes from ewes weighing more than 60 kg.</p>

Abstract
Nanomechanical motion of bacteria adhered to a chemically functionalized silicon surface is studied by means of a microcantilever. A non-specific binding agent is used to attach Escherichia coli (E. coli) to the surface of a silicon microcantilever. The microcantilever is kept in a liquid medium, and its nanomechanical fluctuations are monitored using an optical displacement transducer. The motion of the bacteria couples efficiently to the microcantilever well below its resonance frequency, causing a measurable increase in the microcantilever fluctuations. In the time domain, the fluctuations exhibit large-amplitude low-frequency oscillations. In corresponding frequency-domain measurements, it is observed that the mechanical energy is focused at low frequencies with a 1/fα -type power law. A basic physical model is used for explaining the observed spectral distribution of the mechanical energy. These results lay the groundwork for understanding the motion of microorganisms adhered to surfaces and for developing micromechanical sensors for bacteria.

Abstract
Complex functional materials with three-dimensional micro- or nano-scale dynamic compositional features are prevalent in nature. However, the generation of three-dimensional functional materials composed of both soft and rigid microstructures, each programmed by shape and composition, is still an unsolved challenge. Here we describe a method to code complex materials in three-dimensions with tunable structural, morphological and chemical features using an untethered magnetic micro-robot remotely controlled by magnetic fields. This strategy allows the micro-robot to be introduced to arbitrary microfluidic environments for remote two- and three-dimensional manipulation. We demonstrate the coding of soft hydrogels, rigid copper bars, polystyrene beads and silicon chiplets into three-dimensional heterogeneous structures. We also use coded microstructures for bottom-up tissue engineering by generating cell-encapsulating constructs.

METHODS The study included 34 NSCLC patients (28 females, 6 males) and 44 healthy individuals (17 males, 27 females) as a control group. XIAP and USP8 levels were determined by ELISA. RESULTS The median serum XIAP level of the patients and the control group showed no significant difference. USP8 level was higher in patients than in controls (p<0.0001). In univariate analysis, there was no significant relationship between XIAP and USP8 serum levels and age, sex, performance status, weight loss, stage of disease, histopatological type and response to chemotherapy. Response to chemotherapy did not differ between the high and low XIAP and USP8 groups . There was no significant difference in progression- free survival (PFS) (p=0.432 and p=0.50, respectively) and overall survival (OS) (p=0.989 and p=0.90, respectively) between the low and high XIAP and USP8 groups. CONCLUSION No relationship was found in serum XIAP and USP8 levels with clinical parameters, response to chemotherapy, PFS and OS in patients with advanced stages of NSCLC.

Abstract
PURPOSE The extra benefit of adding chemotherapy to effective endocrine therapy (ET) has not been clearly or consistently identified in patients older than 70 years with estrogen receptor (ER) positive and node positive breast cancer. The aim of this study was to evaluate the efficacy of adjuvant ET vs. chemotherapy plus endocrine therapies (Chemo/ET) in such patients. METHODS In this retrospective multicenter study 191 patients ≥ 70 years with operated hormone receptor breast cancer, who were administered adjuvant ET or Chemo/ET were assessed. RESULTS The median patient follow-up time was 29.0 months (range 1-252). Therefore disease free survival (DFS) and overall survival (OS) analysis was limited, due to the rather short median follow-up, and only 30-month cumulative percentages are reported herein. The 30-month DFS rates were 50.0% in the ET arm and 49.0% in the Chemo/ET arm (p=0.79). The 30-month OS rates were 86% in the ET arm and 96.0% in the Chemo/ET arm (p=0.08). Cox proportional hazard model showed that only surgery was independent prognostic factor for survival (p=0.047), while tumor size showed a strong trend for statistical significance (p=0.051). CONCLUSION The addition of chemotherapy to endocrine therapy in older patients has no significant impact on DFS and OS.

Abstract
The prognosis of advanced soft tissue sarcomas (STS) is poor. The median overall survival (OS) is 6 months in unresectable and metastatic STS that progress after treatment with anthracyclines and ifosfamide. Trabectedin is an alkylating agent, effective in advanced STS, especially in leiomyosarcoma and liposarcoma. In the present study, the effectiveness and safety of trabectedin was retrospectively evaluated in 8 unresectable and metastatic STS patients. Their median age was 47 years. The median progression free survival (PFS) was 3.75 months and the median OS 15 months in relapse or progression after anthracyclines and/or ifosfamide. Toxicities were mainly hematologic. In the present study, trabectedin showed efficacy in different histological subtypes of sarcomas like liposarcoma and leiomyosarcoma.

Abstract
PURPOSE Temozolomide is used concurrently with radiotherapy (RT) and as consolidation therapy in high grade gliomas (HGGs). In the present study we present our experience of long-term efficacy and toxicity of temozolomide in HGGs. METHODS After surgery, temozolomide was administered at 75 mg/m(2) daily concurrently with RT, followed by 6 courses of consolidation therapy (150-200 mg/m(2) for 5 days every 28 days). RESULTS A total of 172 patients with either glioblastoma multiforme (GBM) (n= 142; 82.6%) or anaplastic astrocytoma (AA) (n= 30; 17.4%) were studied. The objective response rate (ORR) was 42.5%, including 12 (7%) complete responses (CRs) and 61 (35.5%) partial responses (PRs). In the GBM group, median progression free survival (PFS) and overall survival (OS) were 9 and 16 months, respectively. In the AA group, median PFS and OS were 16 and 24 months, respectively. Three-year OS was 18.2% for GBM, and 39.4% for AA. In elderly patients (14.5%), median PFS and OS were 8 and 11 months respectively for both HGGs. Serious toxicities were mainly hematologic. CONCLUSION Temozolomide is an effective agent in HGGs with favorable outcome and low toxicity profile even in advanced age.

Abstract
PURPOSE To retrospectively evaluate the efficacy and tolerability of mitomycin-C (MMC) in combination with fluoropyrimidines as salvage 3rd -or 4th-line therapy in metastatic colorectal cancer (MCRC) patients. METHODS All patients in this study had previously failed oxaliplatin and irinotecan-based chemotherapy. Patients were treated with MMC (6 mg/m(2) intravenously/i.v.) on day 1 in combination with either oral UFT (500 mg/m(2)) and oral leucovorin (LV) (30 mg) on days 1-14 every 3 weeks (group A) or infusional 5-fluorouracil (5-FU) by deGramont regimen with i.v. LV (200 mg/m(2)) on days 1 and 2, every 2 weeks (group B). RESULTS Thirty-nine MCRC patients were analyzed. Twenty-two of them were in group A and 17 in group B. Thirty-three were evaluable for clinical efficacy. The clinical benefit in the intent-to-treat (ITT) population was 30.8%. Median progression free survival (PFS) was 6 months (95% confidence interval/ CI 4-8) and median overall survival (OS) 9 months (95% CI 6.5-11.5). Median PFS was 3 months (95% CI 2.4-3.6) in group A and 7 months (95% CI 5.1-8.9) in group B (p=0.009). Median OS was 7 months (95% CI 4.3-9.7) in group A and 12 months (95% CI 5.4-18.6) in group B (p=0.422). The combination of MMC and fluoropyrimidines was generally well tolerated. The most common severe toxicities were nausea and vomiting, neutropenia, hepatotoxicity and diarrhea. CONCLUSION MMC in combination with fluoropyrimidines is safe and active in heavily-pretreated MCRC patients. This combination remains a viable option in these patients. However, better therapies are urgently needed.

Abstract
Tissue engineering based on building blocks is an emerging method to fabricate 3D tissue constructs. This method requires depositing and assembling building blocks (cell-laden microgels) at high throughput. The current technologies (e.g., molding and photolithography) to fabricate microgels have throughput challenges and provide limited control over building block properties (e.g., cell density). The cell-encapsulating droplet generation technique has potential to address these challenges. In this study, we monitored individual building blocks for viability, proliferation and cell density. The results showed that (i) SMCs can be encapsulated in collagen droplets with high viability (>94.2 +/- 3.2%) for four cases of initial number of cells per building block (i.e. 7 +/- 2, 16 +/- 2, 26 +/- 3 and 37 +/- 3 cells/building block). (ii) Encapsulated SMCs can proliferate in building blocks at rates that are consistent (1.49 +/- 0.29) across all four cases, compared to that of the controls. (iii) By assembling these building blocks, we created an SMC patch (5 mm x 5 mm x 20 microm), which was cultured for 51 days forming a 3D tissue-like construct. The histology of the cultured patch was compared to that of a native rat bladder. These results indicate the potential of creating 3D tissue models at high throughput in vitro using building blocks.
