Approximately 50% of tumors are malignant. Neoplasms originating from the mammary gland represent the most common neoplastic disease in canines in Veterinary Medicine. Aim: Relate the expression of the receptor to progesterone (PR) with the tumor stage of canine mammary carcinoma. Material and Methods: Analytical-cross-sectional study, samples of paraffinized tumor tissue obtained from 30 canine patients with breast cancer were used. The expression of PR was performed by immunohistochemical labeling, using murine anti-PR (anti-PR Biocare brand). A descriptive analysis was carried out with the results using the SPSS program. Results: The predominant histological subtype of breast cancer was tubular carcinoma with 12 patients, followed by papillary cystic carcinoma with 6 patients, solid carcinoma 5, carcinosarcoma 4 and comedocarcinoma 3. There was a significant trend between breast cancer subtypes, histological grade G1. Among the histopathological findings, the degree of invasion is related to the presence of tumor cells in adjacent lymph nodes, which is why it is a prognostic indicator. The expression of PR in the tumor tissue samples it was 42.8% positive versus 57.14% negative, of which 75% correspond to G1, 8.3% to G2 and 16.6% to G3. With respect to the relationship of the expression of PR vs type of tumor, it was found that 50% correspond to tubular carcinoma, 33.3% to papillary cystic carcinoma, 8.3% to solid carcinoma and 8.3% to comedocarcinoma. Conclusion: The hormone receptor was negative in more than half of the patients and histological grade is significantly associated with tumor subtypes, this study emphasizes the need to introduce receptor testing into our routine clinical practice to offer the best treatment for breast cancer.展开更多

This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.展开更多

Study Design: A single center retrospective analyses of 470 elective FET cycles which were performed between January 2015 and September 2019 were evaluated. Patients were divided into two groups. Control group was consisted of VP (n = 272), the study group was consisted of VP plus IMP (n = 198) users. Results: The number of transfer attempts in control and study groups was 272 and 198, respectively. Age (29.8 ± 4 vs 30.6 ± 4;p = 0.09), BMI (22 ± 2 vs 21.9 ± 3;p = 0.79) and the number of transferred embryos (1.4 ± 0.5 vs 1.4 ± 0.5;p = 0.48) were comparable between groups. Altough, implantation rates (43.7% vs 43.6%;p = 0.9), ectopic pregnancy (0.8% vs 0.3%;p = 0.46) and abortion rates (8.2% vs 4.8%;p = 0.07) were similar. Biochemical pregnancy rate (8.4% vs 3.4% p = 0.01) in control group and ongoing pregnancy rate (OPR) (27.9% vs 38.1%;p = 0.005) in study group were significantly higher. Conclusion: Within the FET cycles in which good quality blastocyst are being transferred additional IMP supplementation to VP may increase OPR while reducing the biochemical pregnancy rate.展开更多
