AbstractRecently, there has been increased concern about a risk of secondary malignancies (SM) occurring in myelofibrosis (MF) patients receiving ruxolitinib (RUX). In polycythemia vera (PV), on the other hand, only limited data on the risk of SM under RUX treatment are available. To investigate the association between RUX therapy in PV and SM, we conducted a retrospective, single-center study that included 289 PV patients. RUX was administered to 32.9% (95/289) of patients for a median treatment duration of 48.0 months (range 1.0–101.6). Within a median follow-up of 97 months (1.0–395.0) after PV diagnosis, 24 SM occurred. Comparing the number of PV patients with RUX-associated SM (n = 10, 41.7%) with the 14 (58.3%) patients who developed SM without RUX, no significant difference (p = 0.34, chi square test) was found. No increased incidences of melanoma, lymphoma, or solid “non-skin” malignancies were observed with RUX (p = 0.31, p = 0.60, and p = 0.63, respectively, chi square test). However, significantly more NMSC occurred in association with RUX treatment (p = 0.03, chi-squared test). The “SM-free survival” was not significantly different by log rank test for all 289 patients (p = 0.65), for the patients (n = 208; 72%) receiving cytoreductive therapy (p = 0.48) or for different therapy sequences (p = 0.074). In multivariate analysis, advanced age at PV diagnosis (HR 1.062 [95% CI 1.028, 1.098]) but not administration of RUX (HR 1.068 [95% CI 0.468, 2.463]) was associated with an increased risk for SM (p = 0.005). According to this retrospective analysis, no increased risk of SM due to RUX treatment could be substantiated for PV.

A new procedure for nonsurgical deep intrauterine insemination (DUI) in non-sedated sows has recently been reported (Martinez et al. 2002 Reproduction 123, 163–170). In comparison to traditional artificial insemination (AI), using this procedure, a 20-fold reduction in the number of spermatozoa inseminated can be used without a decrease in fertility when hormonally treated post-weaning estrous sows are used. The aim of the present study was to evaluate the effectiveness of DUI under field conditions. In Experiment 1, crossbred sows (2–6 parity) were weaned at 20.75 ± 0.06 days. Estrous detection was performed once per day, beginning 3 days after weaning. Sows with a weaning to estrus interval of 4–5 days were selected to be inseminated. A total of 190 sows were inseminated at 12, 24, and 36 h after onset of estrus using one of the following two regimes: (1) DUI with 150 × 106 fresh spermatozoa in 5 mL of BTS (n = 95) and (2) Traditional AI with 3 × 109 fresh spermatozoa in 100 mL of BTS (n = 95) prepared from the same semen samples used for the DUI group. Farrowing rates (FR) and litter sizes (LTS; mean ± SEM) from both groups were compared using chi-squared test and ANOVA, respectively. There was no significant difference in the FR between groups (83.2 and 86.3% for DUI and AI groups, respectively). However, a decrease (P < 0.001) in the LTS was observed in sows inseminated by the DUI procedure (9.8 ± 0.29 and 10.9 ± 0.17, respectively). In Experiment 2, seventy one natural post-weaning estrus sows were used. Fifty-five sows were DUI inseminated three times with 150 (n = 17), 300 (n = 19), or 600 (n = 19) × 106 spermatozoa in 5, 10, or 20 mL of BTS, respectively. The remaining sows (n = 16) were traditionally inseminated. On Day 6 after estrus, sows were subjected to laparotomy and the tips of both uterine horns were flushed in order to evaluate pregnancy rate (PR: percentage of sows with at least 4 viable embryos) and fertilization rate (ratio of viable embryos to the total number of embryos and oocytes). PR was similar in all the groups, ranging from 84.2% (DUI 300 × 106 spermatozoa group) to 94.7% (DUI 600 × 106 spermatozoa group). Fertilization rate and the percentage of bilateral fertilization after DUI with 600 × 106 spermatozoa did not differ from those of the AI group (97.8 and 100% vs. 98.4 and 100%, respectively), but a significant decrease in both parameters (P < 0.05; chi-square test) was observed in sows inseminated with 300 (94.3 and 87.5%) or 150 (84.4 and 66.7%) × 106 spermatozoa. In conclusion, DUI with 150 × 106 spermatozoa offers similar FR but a lower LTS in sows with natural estrus in comparison with those parameters obtained when traditional AI is used. The lower litter size could be related to the low percentage of bilateral fertilization observed in that group. This work was supported by CDTI 020003.

Background: The SSRIs being used as 1st line therapy in treatment of depression have delayed therapeutic effect which makes the patient vulnerable to an increased risk of suicide and decreased adherence to the treatment and will prematurely discontinue the therapy. The present study was conducted to evaluate if low dose mirtazapine-escitalopram combination therapy has any add on benefit over monotherapy with escitalopram.Methods: In a single-centered, comparative study involving patients with depression attending the out-patient after screening and exclusion, 60 eligible patients were randomly assigned to receive tablet mirtazapine 7.5 mg plus tablet escitalopram 10 mg intervention or tablet escitalopram 10 mg plus placebo intervention in a double-blind 6-week treatment phase. The primary outcome measure was the change in the 17-item Hamilton Depression Rating Scale (HDRS) and Montgomery-Asberg Depression Rating Scale (MADRS) score from baseline. Participants were evaluated at baseline, 1st, 2nd,4th and 6th week. Results were analyzed using Chi-Square test for adverse effects and independent t-test analysis for efficacy parameter.Results: In the analysis of results at 6th week the numbers of patients achieved remission in mirtazapine group are more with a p-value of 0.018 which is significant and the numbers of responders in mirtazapine group are also more which is statistically significant on chi-square test. There is no significant difference was observed between the two groups with reference to occurrence of adverse effect.Conclusions: Adding low dose mirtazapine has an added benefit in terms of efficacy and getting remission early with more number of responders in the treatment of major depression.

Abstract Objective: To test the hypothesis that bonding with a blue light-emitting diode (LED) curing unit produces no more failures in adhesive-precoated (APC) orthodontic brackets than bonding carried out by a conventional halogen lamp. Materials and Methods: Sixty-five patients were selected for this randomized clinical trial, in which a total of 1152 stainless steel APC brackets were employed. In order to carry out a valid comparison of the bracket failure rate following use of each type of curing unit, each patient's mouth was divided into four quadrants. In 34 of the randomly selected patients, designated group A, the APC brackets of the right maxillary and left mandibular quadrants were bonded using a halogen light, while the remaining quadrants were treated with an LED curing unit. In the other 31 patients, designated group B, halogen light was used to cure the left maxillary and right mandibular quadrants, whereas the APC brackets in the remaining quadrants were bonded using an LED dental curing light. The bonding date, the type of light used for curing, and the date of any bracket failures over a mean period of 8.9 months were recorded for each bracket and, subsequently, the chi-square test, the Yates-corrected chi-square test, the Fisher exact test, Kaplan-Meier survival estimates, and the log-rank test were employed in statistical analyses of the results. Results: No statistically significant difference in bond failure rate was found between APC brackets bonded with the halogen light-curing unit and those cured with LED light. However, significantly fewer bonding failures were noted in the maxillary arch (1.67%) than in the mandibular arch (4.35%) after each light-curing technique. Conclusions: The hypothesis cannot be rejected since use of an LED curing unit produces similar APC bracket failure rates to use of conventional halogen light, with the advantage of a far shorter curing time (10 seconds).

ABSTRACT Objective: The purpose of this clinical study was to evaluate the effect of implant body form (cylindrical and conical implants) on crestal bone levels during 6 months' follow-up after loading. Materials and Methods: A total of 32 SPI implants (19 conical implants/13 cylindrical implants) were randomly placed in 12 male patients using a submerged approach. None of the patients had compromising medical conditions or parafunctional habits. Periapical radiographs using the parallel technique were taken after clinical loading and 6 months later. Clinical indices including pocket depth and bleeding on probing (BOP) were recorded on 6-month follow-up. Data were analyzed by independent samples t-test and Chi-square test with a significance level of 0.05. Results: Six months after loading, crestal bone loss was 0.84 (±0.29) mm around the cylindrical implants and 0.73 (±0.62) mm around the conical types, which was not significantly different (P = 0.54). Pocket depth around the cylindrical and conical implants was 2.61 (±0.45) mm and 2.36 (±0.44) mm, respectively (P = 0.13). BOP was observed among 53.8% and 47.4% of the cylindrical implants and conical (P = 0.13). Bone loss and pocket depth in the maxilla and mandible had no significant difference (P = 0.46 and P = 0.09, respectively). Conclusion: In this study, although bone loss and clinical parameters were slightly higher in the cylindrical implants, there was no significant difference between the conical- and cylindrical-shaped implants.

4544 Background: IRI-S had longer in median survival time (MST) than S-1 alone, and was well tolerated in previously untreated AGC, but not statistically significant. Considering 68 patients (pts) were censored, further follow-up was needed to confirm the OS with more precision (Imamura et al. ASCO-GI 2008). We now present updated results of OS and exploratory analysis with the prolonged 2.5 year follow-up data. Methods: Treatments Arm A (oral S-1 80 mg/m2/day from Day 1 to 28, q6w), or Arm B (IRI-S; oral S-1 80 mg/m2/day from Day 1 to 21 and intravenous irinotecan 80 mg/m2 on Days 1 and 15, q5w) were continued until disease progression or unacceptable toxicities were observed. The primary endpoint was to compare OS between groups. This updated result was regarded as exploratory position. Results: Although the MST of Arm A was 319 days (95%Cl: 286–395) and of Arm B was 389 days (95%Cl: 324–459), Arm B didn’t show statistically significant superiority to Arm A (log-rank test p=0.54; hazard ratio (HR) =0.93). The 1-year survival was 45.0% in Arm A and 52.0% in Arm B, and the 2-year survival was 22.5% and 18.0%, respectively. Response rate was significantly different (Arm A/B, 26.9%/41.5%; chi-square test p=0.04) in 187 patient evaluated by RECIST criteria. Time to treatment failure was also favored in Arm B (median=138 days) compared to Arm A (111 days; log-rank test p=0.16; HR=0.85). In subset analyses, two groups showed possibility of clinical benefit in Arm B. The HR of diffuse type group was 0.71 (95%Cl: 0.52–0.96), and of PS1, 2 group was 0.63 (95%Cl: 0.42–0.95). As post protocol treatment, 45.6% of Arm A patients received an irinotecan-based regimen, and the MST of them was 496 days (95%Cl: 395–573). Conclusions: IRI-S did not show statistically significant superiority to S-1 alone in OS with this follow-up data. Post protocol treatment, effective treatment after S-1 failure might have affected survival. According to exploratory analyses, IRI-S may have clinical benefit in early-term of treatment, group of the diffuse type and that of PS1, 2. We need more considering predictive factors, because the gastric cancer is heterogeneous adenocarcinoma. [Table: see text]

Atypical Meningiomas

Abstract BACKGROUND WHO grade II (atypical) meningiomas are treated with surgical resection, often followed by adjuvant fractionated radiation therapy (FRT). The increased availability of frameless stereotactic radiosurgery (SRS) presents an opportunity to offer patients a high biological effective dose over fewer fractions. Here we study the patterns of care and outcomes of these two forms of adjuvant RT. METHODS Patients with atypical meningioma were abstracted from the National Cancer Database (NCDB). Descriptive statistics were reported, and differences between treatment groups were assessed using either a chi-square test or ANOVA. Patients were grouped by treatment type and Kaplan Meier (KM) analysis was performed to compare overall survival (OS) using a log rank test. Univariable (UVA) and multivariable (MVA) cox regression analyses were completed. RESULTS Of 10,015 cases diagnosed from 2004-2016, 7,153 received surgery alone, 2,059 received surgery and adjuvant FRT (S+RT), and 362 received adjuvant SRS (S+SRS). The use of adjuvant RT increased by 71.8% for S+RT and 97.8% for S+SRS. In 2004, 15.1% of 443 registered patients received S+RT and 2.26% received S+SRS, while in 2016 these figures were 26.0% and 4.47%, respectively, for the 1051 registered patients (p&lt; 0.001 and 0.022, respectively). For the 8,636 patients with survival data there was no significant difference in median OS between S+RT and S+SRS (130 months vs. 125 months, log rank p=0.935). On UVA, S+RT conferred better survival compared to surgery alone (HR 0.81 [0.72-0.91], p&lt; 0.001) while S+SRS trended towards better survival (HR 0.82 [0.64-1.06], p=0.124). On MVA, no significant OS benefit was seen with S+RT (HR 0.96 [0.85-1.08], p=0.491) or S+SRS (HR 0.90 [0.69-1.16], p=0.413) versus surgery alone. CONCLUSIONS While the use of adjuvant RT for atypical meningioma has increased substantially since 2004, OS is comparable between FRT and SRS. The data presented here support further prospective investigation of adjuvant SRS.

The aim of the present study was to perform lifetime performance analysis in three pig breeds; Hungarian Large White (n=295), Duroc (n=76) and Pietrain (n=91) on a commercial farm using analysis of survival sows. We took into consideration the age of sows at the time of their inclusion into breeding, their age at the time of culling, time spent in production, number of mating and parities, parity percentage, intervals between litters, number and mean of piglets born alive and born dead, number of raised piglet litters, number and mean of 21 days old piglets, the weight and mean of raised litter and raise percentage. We carried out the analysis by SPSS 22.0. Single factor analysis of variants, Kaplan-Meier analysis and Cox PH model were used. The determination of the significance of risk rates differences was done by Wald chi square test. Our results showed that the average culling age were 1056 (±33.52) days for the Hungarian Large White, 735 (±73.56) days for Duroc and 818 (±71.98) days for the Pietrain. The log rank test of the survival analysis indicated a significant difference between the three tested genotypes (χ2=16.981, P<0.001), which means that the survival percentage of the individual breeds varied significantly from one another. In comparison with the Hungarian Large White genotype the Duroc genotype has a 1.6 times higher (P<0.001) culling risk while that of the genotype Pietrain was 1.36 times higher (P<0.001). Our results can be used to compare the breeds kept under the same conditions and to compare the life span of one genotype under different farming conditions. Factors that increase survival and improve the profitability of pig farming can be determined by this method.

Objective: To perform genotyping for MTR A2756G polymorphism and identification of risk factors associated with head and neck squamous cell carcinoma (HNSCC). Study Design: Cross section, comparative study. Place and Duration of Study: The study was carried out at the Department of Biochemistry of Quaid-i- Azam University, Islamabad from October 2014 to August 2015. Materials and Methods: In this study, 292 diagnosed patients HNSCC and 324 normal individuals without any history of cancer were enrolled. Blood samples of patients and controls were collected in ethylenediamine tetra acetic acid (EDTA) and DNA was extracted using conventional method. All samples were genotyped for the MTR A2756G polymorphism using PCR-RFLP. Frequency of polymorphism was compared between HNSCC patients andcontrols. MultipleLogisticRegression(MLR)andchi-squaretestwasperformedtoexaminetheassociation of MTR A2756G polymorphism with risk factor. Results: Chi-square test of independence showed statistically significant difference among the variables of age, smoking and MTR A2756G genotype (p-value<0.05). Multivariate analysis showed that smoking (adjusted OR, 3.7; 95% CI, 2.3 – 6.0), age groups 41 – 50 years (adjusted OR, 3.6; 95% CI, .9 – 6.7) and > 60 years (adjusted OR, 3.5; 95% CI, 1.7 – 7.3), MTR 2756 AG genotype (adjusted OR, 2.1; 95% CI, 1.3 – 3.5) is associated with increased risk of HNSCC. Conclusion: The results suggest that the genetic polymorphism MTR A2756G is associated with the occurrence of HNSCC in the Pakistani population while the individuals between 40 to 50 years of age and those who are smokers are at a greater risk of developing HNSCC.

Background: Urgent-start dialysis is a major problem for incident dialysis population. Urgent start on hemodialysis is associated with an increased risk of infectious or mechanical complications, and its mortality is equal to or higher than that of urgent start on peritoneal dialysis (PD). However, compared to patients starting PD in a planned setting, those on urgent-started PD have an increased risk of mechanical complications and lower technique survival. Methods: In this study, 101 adult incident dialysis patients (≥18 years old) who underwent Tenckhoff catheter implantation were enrolled. All of the patients were grouped according to the urgent PD mode: the intermittent PD (IPD) or automatic PD (APD) group, and patients were followed for 1 year. The paired or independent t test was used to analyze the change of laboratory variables. Pearson chi-square test was applied to compare the short outcome between the 2 groups. Results: When PD was treated for 7 days and 1 month, the APD group has the lower serum potassium and phosphorus levels than the IPD group. The incidence of catheter dysfunction was significantly lower in the APD group. The morbidity of infection associated with PD in the first year was lower in the APD group despite no significant difference existing. The technique survival and patient survival rate have no evident difference between the 2 groups. Conclusion: Compared to IPD, urgent start on APD could reduce the risk of mechanical complication, which could be considered a gentle, safe, and feasible alternative to urgent start on IPD.

Introduction: Ceftolozane–tazobactam (CT) and ceftazidime–avibactam (CZA) are new beta-lactam/beta-lactamase inhibitors (BL/IBL) and antibiotics. There are few data regarding their impact on Clostridioides difficile infections (CDI). The objective of our study was, therefore, to determine and compare the number of CDI occurring after treatment with CT or CZA and carbapenem (CBP). Methods: All patients who received at least one dose of CT or CZA in our hospital between 1 January 2018 and 31 December 2019 were included. We compared, during the same period, the number of CDI after CT or CZA treatment and CBPs by using a chi-square test of Fischer’s exact test when required. p value < 0.05 was considered as significant. Results: Among the 53 patients receiving CZA and 42 patients receiving CT, two and one, respectively, developed a CDI within 90 days. Of the three (3%) patients who developed a CDI, one died 15 days after his second CDI (36 days after initiation of CZA). Of the 2291 patients receiving CBP, 37 (1.6%) developed a CDI within 90 days. There was no significant difference between the number of CDI occurring after CBP and CT or CZA treatment. CT or CZA use is not associated with an increased rate of CDI compared to CBP.
