Abstract Lamb deaths occurring in the neonatal phase, which covers the first four weeks after birth, cause serious economic losses for farms. This study was carried out on 140 Akkaraman-Kangal sheep that lost their lambs due to pneumonia and enteritis in the neonatal phase during the anestrus period. In the study, an intravaginal sponge containing progesterone was applied to the animals in Group 1 (n:70) on day 0, and 7 days after the application, the vaginal sponges were removed, and 263 µg PGF2α and 500 IU eCG (PMSG) hormone were applied. After removing the intravaginal sponge, rams were introduced for 7 days (between the days 8th and 14th ). Without any manipulations to the animals in Group 2, the ram effect was utilized by performing simultaneous ram introduction with Group 1. To determine the reproductive response, the economic implications between the groups were compared by considering the reproductive parameters such as oestrous rate, pregnancy rate, multiple pregnancy rate, embryonic death rate, number of births, number of offspring, and fertility. The study group created a positive economic difference compared to the control group while analyzing the statistical differences in terms of each reproductive parameter between the study and control groups. When lamb losses are experienced in farms that build their profitability on lamb production, it was concluded that pregnancy should be achieved by sexual stimulation without waiting for the breeding season.

Backgroung: Seasonal anestrus in ewes reduces reproductive efficiency and hinders productivity. Exogenous hormones can be used to facilitate the induction and synchronization of estrus in the anestrus period. The aim of this study was to evaluate the pregnancy rate in ewes after the treatment with different hormones and fixed time artificial insemination. Methods: The ewes were randomly divided in 4 (n=4) groups: Melatonin group (Group 1), Melatonin and Medroxyprogesterone group (Group 2), Medroxyprogesterone group (Group 3) and control group (Group 4). Pregnancy rate, estrus induction rate and litter size were determined and compared. Result: The estrus induction rate in our study was 100% for the first 3 groups and 6.25% for the 4th group. The pregnancy rate was between 4.16% (group 4) and 95.83% (group 2). For the others groups the values were 89.58% for the first group and 91.67%, for the 3rd group. The prolificacy rate was between 1 (control group) and 1.71 (2nd group), with intermediate values for the other 2 groups: 1.21 for 1st group and 1.27 for the 3rd group.

Background: Many guidelines have been issued regarding the number of embryos to be transferred after in vitro fertilization (IVF), but patients and clinicians may be reluctant to accept or offer a single embryo transfer due to the expected lower chance of pregnancy or live birth. This study was aimed to provide additional information on cycle outcome according to the number and quality of thawed transferred blastocysts. Methods:A retrospective cohort study was designed to collect the data of 505 patients who performed the first frozen blastocysts transfer at Tam Anh General Hospital from June 2018 to September 2019. One good-quality embryo was transferred for 121 patients (Group 1), two good for 214 patients (Group 2), one good and one poor for 112 patients (Group 3), one good and two poor for 25 patients (Group 4), and one or two poor for 33 patients (Group 5). Results:The pregnancy rate was 71.9%, 74.8%, 69.4%, 84.0%, and 39.4% in Group 1–5, respectively. The multiple pregnancy rate was 36.9%, 16.9%, and 32.0% in Groups 2–4, respectively, higher than Group 1 (4.9%). The live birth rate was 55.6%, 50.9%, and 60.0% in Group 2–4, respectively, but not significantly different from the Group 1 (47.9%). Conclusions:Transferring an additional good or poor embryo, along with a good embryo, does not increase the live birth rate while the incidence of multiple pregnancies rises significantly.

Vibrio harveyi causes vibriosis in various commercial marine fish species. The infection leads to significant economic losses for aquaculture farms, and vaccination is an alternative approach for the prevention and control of fish diseases for aquaculture sustainability. This study describes the use of formalin-killed Vibrio harveyi (FKVh) strain Vh1 as a vaccine candidate to stimulate innate and adaptive immunities against vibriosis in a marine red hybrid tilapia model. Tilapia are fast growing; cheap; resistant to diseases; and tolerant to adverse environmental conditions of fresh water, brackish water, and marine water and because of these advantages, marine red hybrid tilapia is a suitable candidate as a model to study fish diseases and vaccinations against vibriosis. A total of 180 healthy red hybrid tilapias were gradually adapted to the marine environment before being divided into two groups, with 90 fish in each group and were kept in triplicate with 30 fish per tank. Group 1 was vaccinated intraperitoneally with 100 µL of FKVh on week 0, and a booster dose was similarly administered on week 2. Group 2 was similarly injected with PBS. Skin mucus, serum, and gut lavage were collected weekly for enzyme-linked immunosorbent assay (ELISA) and a lysozyme activity assay from a total of 30 fish of each group. On week 4, the remaining 60 fish of Groups 1 and 2 were challenged with 108 cfu/fish of live Vibrio harveyi. The clinical signs were monitored while the survival rate was recorded for 48 h post-challenge. Vaccination with FKVh resulted in a significantly (p < 0.05) higher rate of survival (87%) compared to the control (20%). The IgM antibody titer and lysozyme activities of Group 1 were significantly (p < 0.05) higher than the unvaccinated Groups 2 in most weeks throughout the experiment. Therefore, the intraperitoneal exposure of marine red hybrid tilapia to killed V. harveyi enhanced the resistance and antibody response of the fish against vibriosis.

AbstractBackground:Case-control studies often analyze risk factors for antibiotic resistance. Recently published articles have illustrated that randomly selected control-patients may be preferable to those with the susceptible phenotype of the organism. A possible methodologic problem with randomly selected control-patients is potential bias due to control group misclassification. This occurs if some control-patients did not have clinical cultures performed and thus might have been unidentified case-patients. If this bias exists, these studies might be expected to report lower odds ratios (ORs) because control-patients would be more like case-patients.Objective:To analyze potential biases that might arise due to control group misclassification and potentially larger selection biases that may be introduced if control-patients are required to have at least one clinical culture.Patients:One hundred twenty case-patients, 770 control-patients in group 1, and 510 control-patients in group 2.Methods:Two case-control studies. Case-patients had clinical cultures positive for imipenem-resistant Pseudomonas aeruginosa. The first group of control-patients were random. The second group of control-patients were identical to those in group 1 except being required to have at least one clinical culture.Results:Univariate analyses showed higher ORs for case-patients versus control-patients in group 1 (imipenem [OR, 12.5], piperacillin-tazobactam [OR, 3.7], and vancomycin [OR, 4.7]) as compared with case-patients versus control-patients in group 2 (imipenem [OR, 8.0], piperacillin-tazobactam [OR, 2.5], and vancomycin [OR, 3.0]).Conclusion:Requiring control-patients to have at least one clinical culture introduces a selection bias likely because it eliminates patients with less severe illness.

Relinqing granule (RLQ) is the best-selling Chinese patent drug for treatment of urinary system diseases. In this study, the effects of RLQ on the pharmacokinetics of ciprofloxacin, sulfamethoxazole, and trimethoprim in SD rats were investigated. Rats were randomly divided into control group 1, control group 2, RLQ group 1, and RLQ group 2. RLQ group 1 and RLQ group 2 were treated orally with RLQ for 7 days, and rats were treated with the same volume of water in control group 1 and control group 2. Then, RLQ group 1 and control group 1 were given intragastrically ciprofloxacin on day 8, while RLQ group 2 and control group 2 were given intragastrically sulfamethoxazole and trimethoprim on day 8. Blood samples were collected and determined. There was no significant influence of pharmacokinetic parameters of trimethoprim on two groups. But some pharmacokinetic parameters of ciprofloxacin and sulfamethoxazole in RLQ pretreated rats were evidently altered (P < 0.05), which indicated that absorption of ciprofloxacin and sulfamethoxazole in RLQ pretreated rats was significantly affected. It indicated the coadministration of RLQ would have an influence on the efficacy of ciprofloxacin and sulfamethoxazole, and the doses of ciprofloxacin tablet and compound sulfamethoxazole tablet need adjustment.

Objectives: The aim of this study was to explore the cytomorphometric and morphological effects of Trichomonas vaginalis in exfoliated epithelial cells. Study Design: Ninety-six Pap-stained cervical smears were divided into a study group and two control groups as follows: T. vaginalis cases, a first control group with inflammation, and a second control group without inflammation. Micronucleated, binucleated, karyorrhectic, karyolytic, and karyopyknotic cells and cells with perinuclear halos per 1,000 epithelial cells were counted. Nuclear and cellular areas were evaluated in 70 clearly defined cells in each smear using image analysis. Results: The frequencies of morphological parameters in the T. vaginalis cases were higher than the values of the two control groups, and the difference among groups was found to be significant (p < 0.05). The nuclear and cytoplasmic areas of epithelial cells were diminished in patients with trichomoniasis. The mean nucleus/cytoplasm ratio in T. vaginalis patients was higher than the value in the control groups, and the difference between the study group and control group 1 was significant. However, there was no statistically significant increase between the study group and control group 2. Conclusions:T. vaginalis exhibited significant changes in the cellular size and nuclear structure of the cells. The rising frequency of micronuclei, nuclear abnormalities, and changing nucleus/cytoplasm ratio may reflect genotoxic damage in trichomoniasis.

Aim. To study the neuroprotective effect of a repeated course of low dose cortexin therapy on the quality of life in the early rehabilitative period after hemispheric ischemic stroke (IS). Materials and methods. 90 patients were divided into group 1 treated with cortexin (10 mg i/m twice daily (morning and afternoon) in addition to basal treatment, group 2 given the repeated course of the same treatment, and control group (basal therapy alone). The standard SF-36 questionnaire was used to assess the quality of life. Results. Treatment of patients following acute hemispheric ischemic stroke with cortexin (10 mg i/m twice daily) and the repeated course of the same treatment after 10 days resulted in the accelerated and more complete normalization of the quality of life in the early rehabilitation petriod (starting from days 21-27 days after the onset of disease) than in the patients given a single course of cortexin therapy or basal treatment alone.

Background: Evaluation of feasibility, safety and effectiveness of percutaneous nephrolithotomy (PCNL) in different age groups.Methods: Between July 1997-October 2012, 233 patients who were 65 years old and older were included in this study. These patients were divided into two age subgroups used in gerontology research. Group 1 was defined as patients 65-74 years old, Group 2 was older than 74 years old. Data from patient records, including demographic characteristics, preoperative evaluation, operative details, and complications were retrospectively analyzed and compared with control group data.Results: The mean age of 233 patients was 69.7±4.6 years. The mean operative times for Group 1, group 2 and the control group were 76.2±47.3mins, 92.9±47.6mins, 77±44mins, respectively and there was no statistically significant difference between groups 1 and 2 and the control group (p>0.05). Twenty-eight of the 233 patients (12%) needed blood transfusion due to perioperative bleeding. The transfusion rates of groups 1 and 2 were 11.3% and 16.7%, respectively. There was no statistically significant difference between the study groups and control group for blood transfusion rates (p>0.05). There was no statistically significant difference in complications between the study and control groups (p>0.05).Conclusions: In geriatric patients, stone-free rates, transfusion rates and other operation parameters are similar to younger populations when experienced surgeons perform PCNL. Despite comorbidities and decreased body reserve, PCNL can be performed without a significant increase in complications in different ages.

Background: Labour is the most perilous journey a woman has to undertake. Painless and short labour is desired by every woman and is a constant aim for obstetrician.Objective: To analyze and compare the efficacy and safety of drotaverine and valethamate with control group on improving cervical dilatation and promoting progress of labour. Method: Three hundred demographically similar women, both primigravida and multigravida with a term pregnancy in established labour were randomly divided into three groups. One hundred women (group 1) were given injection valethamate intramuscularly,100 women (group 2) were given drotaverine and the rest 100 (group 3) were not given any drug. Comparative analysis was carried out as regards to duration of first stage of labour, mode of delivery, maternal side effects and fetal outcome. Results: The mean duration of active phase of labour in group 1, 2 and 3 was 254.29±96.621 min, 178.31±73.412 min and 346.31±123.351 min respectively. The duration of injection to end of first stage of labour in valethamate and Drotaverine group was 228.12±84.626min and 168.89±69.576min respectively (p value<0.0001). The duration of injection to delivery in Valethamate was 249.13± 88.321 min and in Drotaverine was 192.56±75.479min (p value<0.0001). There were no serious maternal and fetal adverse effects in any group but minor side effects were more common in valethamate group. Conclusion: The reduction of the duration of the first stage of labour was apparently more in drotaverine group as compared to valethamate and control group. Drotaverine was found to be safe with minimal or no adverse effect on the mother and the fetus.

The negative effect of some diseases, such as bovine viral diarrhea (BVD), infectious bovine rhinotracheitis (IBR), and Leptospirosis, on bovine reproduction rates are well known. The uses of vaccines are considered to be an important tool available in order to control reproductive losses but their efficiency is still controversial. The aim of this study was to evaluate the effects of vaccination against BVD, IBR, and Leptospirosis to improve pregnancy rate in beef cattle submitted to fixed-timed AI (FTAI). Nelore cows (n = 1172) from 4 beef cattle farms in Brazil were randomly distributed in two experimental groups: Group 1 (treated, n = 584) received the first dose of the inactivated vaccines (Bioleptogen and Bioabortogen H, Biogénesis Bagó, Garín, Argentina) at the beginning of the FTAI protocol and the second dose on the pregnancy diagnostic 40 days later; Group 2 (control group, n = 588) received 0.9% saline solution. Serum samples from 3–5% of animals in each farm herd were collected to determinate IBR, BVD, and Leptospirosis challenges, by using ELISA protocol for BVD and IBR (Synbiotics BVD p80 ab monoblocking test and Synbiotics BoHV-1 gB monoblocking test, respectively; Synbiotics Corp., Kansas City, MO, USA); and microaglutination test for Leptospirosis. All animals were submitted to the FTAI protocol: D0 = intravaginal P4 device (Cronipress, Biogenesis Bagó) and application of 2 mg oestradiol benzoate (Bioestrogen, Biogénesis Bagó); Day 8 = intravaginal device removal + 0.5 mg oestradiol cipionate (E.C.P, Zoetis Inc., Florham Park, NJ, USA) and 25 mg D-cloprostenol sodium (Croniben, Biogénesis Bagó) and FTAI after 48 h. Body condition scores (BCS) were measured on Day 0 and pregnancy diagnostic were performed on Day 40. Data were analysed by logistic regression using PROC LOGISTIC procedure of the SAS software (SAS 9.3, SAS Institute, Inc., Cary, NC, USA) as well as the significant differences between the factors was analysed to nonparametric statistical frequency (chi-square test; PROC FREQ). Pregnancy rates on day 40 were greater (P < 0.0001) in Group 1 (58.21%; 340/584) compared to Group 2 (44.73%; 263/588). Effect in BCS by pregnancy rates was observed (P = 0.0165) among animals with higher compared to lower BCS (61.40% v. 47.98%, respectively). Results from BVD, IBR and Leptospirosis prevalence were respectively (78.26%; 95.65%, and 10.20%), demonstrating that all herds were challenger for the 3 agents and a positive correlation with pregnancy rates (P < 0.001) in vaccinated group. In conclusion, vaccination with Bioabortogen H and Bioleptogen contributed to increase pregnancy rates in beef cattle submitted to FTAI; and the positive correlation between high prevalence of BVD, IBR, and leptospirosis, and an increased pregnancy rate by 13.48% can be due to fewer losses caused by the vaccination protection up to Day 40.
