AbstractIntroduction: Prostate carcinoma is the most frequent malign neoplasm among men with an ever-growing incidence rate. TMPRSS2-ERG fusion transcript leads to the androgen induction of ERG proto-oncogenes expression, representing a high presence of oncogenes alteration among prostate tumour cells.Aim: The aim of this research was to detect and evaluate theTMPRSS2-ERG fuse transcript in the tissues of patients with prostate cancer, and establish a base of material of these samples for further genetic examination.Materials and methods: The research was a prospective clinical study that involved and focused on random sampling of 101 patients (62 with prostate cancer-study group and 39 with benign changes in the prostate-control group). Real time PCR analysis for detection of the TMPRSS2-ERG fusion transcript in prostate tissue was performed and also data from the histopathology results of tissues were used, as well as data for the level of PSA (prostate-specific antigen) in blood.Results: TMPRSS2-ERG fusion transcript was detected in 20 out of 62 (32.2%) patients with prostate carcinoma and among no patients with benign changes whatsoever. There were no significant differences between patients with/without detected TMPRSS2-ERG fusion related to Gleason score. Among 50%, in the study group this score was greater than 7 per/for Median IQR=7 (6-8). Significant difference was recognized, related to the average value of PSA in favour of significantly higher value of PSA in the study group with prostate cancer, but there was also no significant difference between samples with prostate cancer who were with/without detected TMPRSS2-ERG fusion transcript related to PSA level.Discussion: The results from this research are in accordance with the values and results from analyses done in several research centres and oncological institutes.Conclusion: The positive findings in small scale studies encourage the implementation of larger scale studies that will be enriched with results of genetic transcript in blood and urine and will define the positive diagnostic meaning of the TMPRSS-ERG fusion transcript.

BACKGROUND: Postmenopausis is a period that begins one year after the last menstrual period. Abnormal uterine bleeding could be of different origins. AIM: This study aimed to determine the association of serum estrogen hormone levels and obesity with the occurrence of endometrial bleeding in post-menopausal women. MATERIAL AND METHODS: Prospective clinical study involving 120 postmenopausal patients treated at the University Clinic for Gynecology and Obstetrics-Skopje, divided into two groups: control and study. The control group consisted of 40 postmenopausal patients without endometrial bleeding, hospitalised and operated due to urogenital pathology. The study group consisted of 80 patients with endometrial bleeding who were divided into three subgroups according to the thickness of the endometrium: from 5-8 mm, 8-11 mm and above 11 mm. In all subjects, estradiol and BMI was determined. RESULTS: Estradiol levels were statistically higher in the study group compared to control while statistically significant difference among the three subgroups according to the thickness of the endometrium about the levels of estradiol in blood is not found. About BMI, the results showed that there was no statistical significance between the two examined groups. CONCLUSION: Patients with endometrial bleeding have increased levels of estradiol and are at increased risk of endometrial cancer about controls, the likelihood of endometrial cancer significantly increases by 1,108 times.

Abstract Purpose To determine whether topical tobramycin 0.3%/dexamethasone 0.1% plus ozonized oil eye drops reduces clinical signs and infectious viral titers of presumed viral conjunctivitis more than tobramycin/dexamethasone eye drops alone. Methods Prospective, single-blind, randomized, parallel-groups trial. Eighty patients with a clinical diagnosis of presumed viral conjunctivitis were randomizedly divided into two treatment groups: a study group and a control group, 40 for each group. Patients in the study group received topical tobramycin 0.3%/dexamethasone 0.1% eye drops, plus ozonized oil eye drops, both four times daily; patients in the control group received only topical tobramycin 0.3%/dexamethasone eye drops four times daily. The treatment was for seven days in both groups. Swabs were taken from the conjunctival fornix for adenovirus PCR analysis on the day of recruitment and at seven days follow-up. Clinical signs were also recorded on the day of recruitment and at follow-up examination: the main outcomes were conjunctival injection and conjunctival chemosis, graded on a 4-point clinical scale, presence or absence of superficial punctate keratitis and subepithelial corneal infiltrates. Results No statistically significant difference was reached in adenoviral infection negativization between the two groups, although the study group showed a higher number of PCR negative results at seven days follow-up. PCR real time detected adenoviral infection in 17 of 24 patients on the day of recruitment and it was positive in 4 patients on the seventh day (viral positivity reduction of 76%). In the control group PCR was positive for adenovirus in 18 of 24 patients on the day of recruitment and in 7 patients at seven days follow-up (reduction of 61%). There was statistically significant difference on conjunctival clinical signs between the study and control groups. Significant difference was also found on superficial punctate keratitis resolution between the study and the control group. In the former superficial punctate keratitis was detected in 14 eyes on the first day and in 5 eyes after seven days while in the latter superficial punctate keratitis was found in 124 eyes on the first day and in 6 eyes on the seventh day. No difference was found in subepithelial corneal infiltrates appearance between the two groups. Conclusions The use of ozonized-oil containing eye drops in combination with topical tobramycin 0.3%/dexamethasone 0.1% eye drops four times daily seems to reduce the signs of conjunctivitis, and the duration of viral infection, although it does not affect the subepithelial corneal infiltrates appearance.

PURPOSE: To determine whether a diet low in fat and high in fruits, vegetables, and fiber may be protective against prostate cancer by having an impact on serial levels of serum prostate-specific antigen (PSA). METHODS: Six hundred eighty-nine men were randomized to the intervention arm and 661 to the control arm. The intervention group received intensive counseling to consume a diet low in fat and high in fiber, fruits, and vegetables. The control group received a standard brochure on a healthy diet. PSA in serum was measured at baseline and annually thereafter for 4 years, and newly diagnosed prostate cancers were recorded. RESULTS: The individual PSA slope for each participant was calculated, and the distributions of slopes were compared between the two groups. There was no significant difference in distributions of the slopes (P = .99). The two groups were identical in the proportions of participants with elevated PSA at each time point. There was no difference in the PSA slopes between the two groups (P = .34) and in the frequencies of elevated PSA values for those with elevated PSA at baseline. Incidence of prostate cancer during the 4 years was similar in the two groups (19 and 22 in the control and intervention arms, respectively). CONCLUSION: Dietary intervention over a 4-year period with reduced fat and increased consumption of fruits, vegetables, and fiber has no impact on serum PSA levels in men. The study also offers no evidence that this dietary intervention over a 4-year period affects the incidence of prostate cancer during the 4 years.

Objectives: Prostate cancer (PCa) is a common malignancy affecting elderly male. At present, PCa is estimated using serum prostate-specific antigen (PSA). Prostate biopsy remains the gold standard to confirm the diagnosis of PCa. In this preliminary study, we have assessed the feasibility of detecting PCa using voided urine by targeting the genomic vasoactive intestinal peptide receptor (VPAC) expressed on malignant PCa cells. Material and Methods: Patients ≥40 years old, with no lower urinary tract symptoms (LUTS) and serum PSA levels of <1.6 ng/mL formed the control group and patients ≥40 years old, with LUTS and serum PSA >2.6 ng/ mL formed the study group. Patients were advised to give the first 50 mL of voided urine sample for the detection of malignant markers by targeting the VPAC. The results of histopathological studies were then compared to the results of urine biomarker. Results: The study revealed absence of malignant markers in 75 patients (control group). In the study group, all the 33 patients with adenocarcinoma were positive for malignant markers in the biomarker study and absence of malignant markers in the 32 patients with benign histology. The results of the biomarker studies and histopathology were consistent with each other. Conclusion: This preliminary study validates our belief that patients with PCa do shed malignant cells in the urine which can be identified by targeting the VPAC. The investigation is easy and our data appear to be highly encouraging and further serve as a simple, reliable, and a non-invasive tool in the detection of PCa.

Prostate-specific antigen (PSA) is the one of the most valuable tumor markers for the early detection and management of prostate carcinoma, but not an ideal one because of poor specificity in the case of prostatic hypertrophy and other benign conditions. In order to overcome this drawback some other parameters as is free to total ratio (F/T) PSA and PSA density (PSAD) are introduced. It has been investigated in 60 patients, 18 of them are proved to be found prostate cancer and other 42 were identified as benign prostatic hyperplasia. Patients with CaP had TPSA median of 11.4 ng/ml and the others with benign prostatic hyperplasia (BPH) had 6.9 ng/ml. In these two groups there was statistical significant difference (p 0.01). By receiver operating characteristics curve (ROC) estimated cutoff for TPSA was 4.0 ng/ml with 95% sensitivity, 30% specificity and area covered by ROC was in amount of 0.76. Median F/T ratio for patients with prostate cancer was 0.10, and for benign prostatic hyperplasia patients it was 0.25.For these values there is also statistical difference (p). Using ROC cutoff for F/T PSA was determined at the value of 0.18 with sensitivity 95%, specificity 80% and area under the curve (AUC) 0.93. Median for PSAD in the group with CaP was 0.38 and in the BPH group was 0.16. There was statistical significance within those two groups. In conclusion F/T PSA, PSAD and TPSA are valuable tumor markers in distinguishing patients with CaP ant those without with modestly raised TPSA. Also F/T PSA showed up as better marker than TPSA and PSAD in investigated group of patients.

Purpose: To investigate the influence of a combination of abiraterone and prednisone on serum chromogranin A (CgA) and neuron-specific enolase (NSE) in patients with metastatic castrationresistant prostate cancer (mCRPC) without previous chemotherapy, so as to provide reference data for drug therapy of prostate cancer. Methods: A total of 103 mCRPC patients without chemotherapy from January 2013 to March 2017 were included in this retrospective study. Seventy-one (71) patients received prednisone combined with abiraterone (study group), while 32 patients accepted prednisone (control group). The CgA, NSE and prostate-specific antigen (PSA) in the two groups were monitored, while PSA progression-free survival (PSA-PFS), radiographic PFS (rPFS), and overall survival (OS) were determined during follow-up. Results: PSA-PFS, rPFS and OS in the study group were significantly higher than those in the control group (p < 0.05). The increased proportion of CgA or NSE in the study group was significantly lower than that in the control group at 6 months of treatment (p < 0.05). The occurrences of NED before treatment and 6 months after treatment were both independent predictors of PSA and radiographic progression in the study group (p < 0.05). Conclusion: The combination of prednisone and abiraterone is helpful for prognosis in mCRPC patients that are not on chemotherapy. The occurrence of NED predicts mostly poor prognosis of mCRPC patients on a combination of abiraterone and prednisone

Background: Prostate cancer (PCa) is the sixth primary cause of cancer death. However, conflicts are present about the efficacy and safety of Non-steroidal anti-androgens (NSAA) for its treatment. The aim of this study was to assess the efficacy and safety of NSAAs versus any comparator for the treatment of advanced or metastatic PCa (mPCa). Methodology: MEDLINE and the Cochrane Library were searched. References of included studies and clinicaltrials.gov were also searched for relevant studies. Only English language studies after 1990 were considered for review. Randomized controlled trials (RCTs) examining the efficacy and safety of NSAAs as compared with any other comparator including surgery or chemotherapy in mPCa patients were included. The outcomes include efficacy, safety and the tolerability of the treatment. The Cochrane Risk of Bias Assessment Tool was used for quality assessment. Two authors were independently involved in the selection, extraction and quality assessment of included studies and disagreements were resolved by discussion or by consulting a third reviewer. Results: Fifty-eight out of 1307 non-duplicate RCTs with 29154 patients were considered for the review. NSAA showed significantly better progression-free survival [PFS] (Hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.46-0.78; P=0.0001), time to distant metastasis or death [TTD] (HR, 0.80; 95% CI 0.73-0.91; p<0.0001), objective response (Odds ratio [OR], 1.64; 95% CI 1.06-2.54; P=0.03) and clinical benefits (OR, 1.33; 95% CI 1.08-1.63; P=0.006) as compared to the control group. There was no significant difference observed between the groups in terms of overall survival (HR, 0.95; 95%CI, 0.87-1.03; P=0.18) and time to progression (HR, 0.93; 95% CI 0.77-1.11; P=0.43). Treatment-related adverse events were more with the NSAA group, but the discontinuation due to lack of efficacy reason was 43% significantly lesser than the control group in patients with mPCa. Rest of the outcomes were appeared to be non-significant. Conclusion: Treatment with NSAA was appeared to be better efficacious with respect to PFS, TTD, and response rate with considerable adverse events when compared to the control group in patients with metastatic PCa.

Abstract Introduction Good hearing in pilots, including central auditory skills, is critical for flight safety and the prevention of aircraft accidents. Pure tone audiometry alone may not be enough to assess hearing in the members of this population who, in addition to high noise levels, routinely face speech recognition tasks in non-ideal conditions. Objective To characterize the frequency-following response (FFR) of a group of military pilots compared with a control group. Methods Twenty military pilots in the Study Group and 20 non-pilot military personnel, not exposed to noise in their work, in the Control Group, all with normal hearing, aged between 30 and 40 years old, completed a questionnaire to assess their hearing habits, and their FFRs were measured with a /da/ syllable (duration 40 milliseconds, speed 10.9/s), at 80 dB NA in the right ear. All procedures were approved by the ethical committee of the institution. Statistical analysis was performed using the t-Student or Mann-Whitney tests for quantitative variables, and the Fisher or chi-squared tests for qualitative variables, and a value of p < 0.05 was considered to be statistically significant. Results There was no significant difference between the groups regarding auditory habits. In the FFR, wave amplitudes A (p = 0.01) and C (p = 0.04) were significantly lower in the Study Group. Conclusion Working as a military pilot can be a crucial factor in determining an individual's typical FFR pattern, demonstrated in the present study by statistically significant reductions in the amplitudes of the A and C waves.

Background and Purpose: Lactobacilli play a vital role in protecting the vagina against pathogens. Cytokines are vital components of defense against infections in women. The genital mycoplasmas, Mycoplasma genitalium and Ureaplasma urealyticum, are associated with various infectious diseases in adults and infants. The objective of our study is to identify differences in cytokine profile and Lactobacillus species dominance between a study group of non-pregnant pre-menopausal women with genital M. genitalium or U. urealyticum colonization and a control group of non-pregnant pre-menopausal women without genital M. genitalium or U. urealyticum colonization. Methods: A real-time polymerase chain reaction was performed to measure Lactobacillus species in vaginal swab samples. Cytokine analysis was performed using multiplex immunoassay techniques. Analysis of variance confirmed a significant difference in cytokine profiles between patient groups, with t-tests identifying the most significantly different cytokines. Categorical data analysis identified significant patterns of relative Lactobacillus species dominance in the study group. Results: Lactobacillus iners was the predominant Lactobacillus species in the control group ( p = 0.005). There were no dominant Lactobacillus species observed in the study group. Vascular endothelial growth factor A ( p = 0.002), interleukin-8 ( p = 0.001), and interleukin-1β ( p = 0.049) were expressed significantly higher in the study group, whereas interleukin-1 receptor antagonist ( p < 0.001), interleukin-10 ( p = 0.001), interleukin-12 ( p = 0.002), and interferon-γ ( p = 0.022) were expressed higher in the control group. Association matrices for cytokines were significantly different between two groups ( p < 0.001), with mostly negative associations in the control group and mostly positive associations in the study group. Conclusion: Cytokine levels, their associations, and the patterns of Lactobacillus species dominance are observed to significantly diverge on the basis of M. genitalium and U. urealyticum colonization among non-pregnant pre-menopausal women.
