Ureteral triplication is a very rare anomaly found in the upper urinary tract. This condition can be connected with a higher incidence of congenital anomalies and predisposition for urinary ...infections. Operative procedure is considered in cases where symptoms reduce the patient's quality of life. The type of surgical treatment depends on symptom manifestation. The risk of renal failure is usually a deciding factor, which can be found in conditions such as vesicoureteral reflux, obstruction, ureteral ectopy and recurrent infections. Simultaneous treatment of upper and lower urinary tract can be performed. We report a case of a 38-year-old female patient diagnosed with cervical carcinoma, where ureteral triplication was detected incidentally during a radical operative procedure. Keywords: Ureteral triplication; Cervical carcinoma; Congenital anomalies
Uterine rupture during pregnancy is a critical obstetric complication associated with maternal and fetal mortality and morbidity. The risk is increased in patients with a history of previous uterine ...surgery including cesarean section, myomectomy, salpingectomy, as well as uterine and placental anomalies and polyhydramnios. It can also occur spontaneously. We present a case of uterine rupture in the early third trimester in a woman who had undergone previous laparoscopic removal of the left fallopian tube due to sactosalpinx and laparotomic removal of left uterine horn due to ectopic pregnancy. Key words: Pregnancy; Third trimester; Uterine rupture; Cornual resection; Salpingectomy
Hemiperitoneum caused by venous bleeding from the hilum of the spleen is a rare cause of acute abdomen in the last trimester of pregnancy.
We are presenting a case of a twenty-nine-year-old primipara ...with the clinical picture of acute abdomen.
Primipara in the 36th week of pregnancy presented with the clinical picture of acute abdomen with the ultrasound finding of free fluid in the abdominal cavity and foetal bradycardia. Considering the clinical picture of the mother and the risks for the foetus, it was decided to complete the pregnancy with an emergency caesarean section. During the procedure, exploration of the abdominal cavity found the bleeding site from the venae gastricae breves, and a surgeon stopped active bleeding.
Non-obstetric bleedings are not common in pregnancy, but they are life-threatening both to the mother and the foetus. The exact cause is usually found during the surgical procedure. If a pregnant woman presents with a clinical picture of abdominal pain, and the signs of foetal distress or clinical instability of the mother are also present, an emergency surgical procedure is indicated. In this case, the indication was foetal bradycardia, and the child was born alive by a caesarean section, while an extended surgical procedure saved the mother's life.
Paraoxonase 1 (PON1) is the enzyme that removes carcinogenic radicals from lipids. The aim of the study was to investigate the differences in PON1 activity and oxidation stress parameters between ...patients with cervical intraepithelial neoplasia (CIN) and healthy controls.
The study included 65 women with CIN and 109 healthy women. Lipid parameters were determined on Cobas Integra 400 plus (Roche, Mannheim, Germany). Tiols and reduced glutathione (GSH) were determined spectrophotometric using Eliman reagent. Activity of PON1 was assessed with two substrates, paraoxon and phenylacetate by spectrophotometric method. Malondialdehyde (MDA) was determined by high performance liquid chromatography (Shimadzu Corporation, Kyoto, Japan). Mann-Whitney-test, t-test, χ2-test, correlation and logistic regression was used in statistical analysis. P < 0.05 was considered statistically significant.
The basal (P = 0.929) and NaCl-stimulated (P = 0.985) PON1 activity and activities standardised on the concentration of high-density lipoprotein (HDL; P = 0.076; P = 0.065, respectively) and apolipoprotein AI (apo AI; P = 0.444; P = 0.499, respectively) as well as PON1 phenotypes (P = 0.842) did not differ significantly between the groups. The PON1 arylesterase activity (53±19 kU/L vs. 77±17 kU/L; P < 0.001) and HDL-standardized activity (37 (28-44) kU/mmol
. 43 (37-50) kU/mmol; P < 0.001) and apoAI (29±11 kU/g
. 44±11 kU/g; P < 0.001) was significantly reduced in the CIN group. The concentration of the thiol groups was similar (P = 0.519), of MDA was lower (0.39 (0.27-0.55) µmol/L
. 0.76 (0.57-1.15) µmol/L; P < 0.001) and of GSH was higher (112.0 (66.0-129.6) µg/mL
. 53.4 (34.8-134.4) µg/mL; P < 0.001) in the CIN group.
Reduced PON1 arylesterase activity, lower MDA and higher GSH concentration were observed in CIN patients.
Purpose
Most site-specific cancer incidence is increased with the decrease of glomerular filtration rate (GFR). We analyzed endometrial cancers depending on different type, staging, and histology ...grades. We hypothesized that patients with lower GFR levels have an increased risk for higher staging and histology grades of endometrial cancers.
Methods
Patients were divided into two subgroups regarding GFR; the first group with GFR < 60 ml/min and the second group with GFR > 60 ml/min and regarding different histology grades and cancer stages. Cancers were also divided by stages (1–4). Patients were followed up during 1 year through regular controls in the outpatient clinic and during that time cancer recurrence was recorded.
Results
GFR was the strongest predictor for higher cancer histology grade and higher cancer staging. Patients with reduced GFR had OR for higher histology grade and higher staging of 1.06 and 1.06. Traditional risk factors for endometrial cancer development were not associated with higher histology grade or higher cancer staging.
Conclusion
Higher staging and histology grades in patients with endometrial cancers are associated with reduced GFR. Patients with mild-to-moderate CKD had significantly higher number of cancers with higher histology grades and higher stages than patients with mild or normal GFR category. Decline in GFR was independently associated with more aggressive cancers without other well-known risk factors for endometrial cancer development like age, menopause, diabetes, and obesity.
Background and purpose: Prunus spinose L. is a traditionally consumed, recently scientifically reexamined plant. Brain bioavailability and functionality of polyphenols (PPH) of blackthorn flower ...extract (PSE) was investigated.Materials and methods: C57BL/6 mice received oral daily repeated doses of 25 mg/kg body weight of total PSE polyphenols for 28 days. Brain concentrations of individual polyphenols from PSE were determined by UPLC/MS on 1st,7th, 14th, 21st, and 28th day. Brain antioxidative defense markers were examined as indicators of functionality after bioaccumulation.Results: A total of 68.7% PPH present in PSE were detected in the brain. Higher (p≤0.05) Cmax/AUClast in the PSE treatment vs. control group was recorded for 59.1% of brain detected compounds, indicating relatively good bioaccumulation in the brain. The highest present compounds in PSE were not necessarily the ones mostly bioapsorbed in the brain. Kaempherols were not significantly distributed, opposite to phenolic acids, quercetins or epicgaloatechin-3-gallate. The compounds with the highest concentrations on 28th day were 4-p-coumaroylquinonic acid, (-)-epicatechin, quercetin-3-O-rutinoside, quercetin–rhamnoside, kaempherol-3-rutinoside and quercetin-3-gucoside. Brain lipid peroxidation (MDA) decreased (p<0.05) on the 21st and 28th day in the PSE group. Increase (p<0.05) in GSH concentration was observed on the 21st and 28th and SOD activity on the 28th day. Catalase activity was unchanged. It could be hypothesized that highest PPH concentration-ratios, caused reduction of lipid peroxidation by radical scavenging and simultaneous induction of glutathione and SOD pathways.Conclusions: Screened compounds could be candidates for examining or creation of brain targeted “neuro-nutriceuticals” polyphenol mixtures.
The 20-year experience with large loop excision of the transformation zone (LLETZ) at Gynecologic Oncology Unit, Department of Gynecology and Obstetrics, Sestre milosrdnice University Hospital Centre ...from Zagreb is presented. This retrospective observational study included 1407 women with cervical dysplasia treated by LLETZ technique during the 1995-2016 period. LLETZ was most commonly performed in the 25-35 age group (51%), followed by the 36-45 age group (22%), and least frequently in the >65 age group (2%). Histopathologic results lower than high-grade squamous intraepithelial lesion were found in 23% and high grade squamous intraepithelial lesion or worse findings in 77% of patients. Positive margin as a sign of possible residual dysplasia was found in 25% of cones, 80% of which included endocervical positive margin. Cervical canal biopsy result was positive in 18% of cases. Accurate colposcopy and its findings can help avoid overtreatment, the rate of which was higher than expected in our retrospective study. Long-term follow up is an imperative for proper assessment of the procedure success. This method is the best choice for complete disease removal without unnecessary overtreatment, but it requires continuous education and training of the whole team.

•The functional beveragesare excellent delivering means for nutrients and bioactive molecules.•Use of medicinal and aromatic plants in the production of functional beverages has ...become increasingly popular due to specific content ofstructurally diverse bioactive molecules withnumerous confirmed healthbenefitsand specific sensory properties.•The quality of plant extracts and essential oils depends on quality of raw materials and applied extraction techniques.•Rising consumer demand for natural ingredients provides numerous opportunities for the fortification and development of new categories of functional beverages based on medicinal and aromatic plants.
The functional beverages (FBs) are an important segment of functional food products due to health benefits they provide and their appealing sensory characteristics, suitability and affordability. FBs market offers many opportunities for new product development (nutraceuticals, colorants, plant-based medicines and products) with desirable and effective composition ofnutrients and bioactive molecules (BAMs) aimed to deliver health benefits and improve human well-being. Recently, the use of medicinal and aromatic plants (MAPs) in the production of FBs has become increasingly popular due to specific content of nutrients (amino and fatty acids) and BAMs (volatile and non-volatile) attributed to the biological effects and health benefits. BAMs are stored in leaves, flowers, fruits, seeds, barks and roots, and they mostly include phenolics (phenolic acids, flavonoids, tanins, anthocyanins, lignans and stilbenes), essential oils (EOs), terpenoids, alkaloids, phytosterols and saponins. The aromatic features of MAPs are mainly related to volatile compounds of EOs, but the presence of non-volatile compounds, such as phenolics, also contributes to the specific sensory properties. Phytochemical profiling of plant species containing specific and complex mixtures of BAMs, provides numerous opportunities for the development of new categories of FBs, but also opens new challenges in their isolation using conventional and advanced extraction techniques, as well as determination of potential biological effects. This review summarizes the categories of the most common FBs, BAMs from selected MAPs and their biological effects, extraction techniques suitable for production of plant extracts and EOs, product quality and prediction trends, and several directions towards future research on FBs development strategies.
Human papillomavirus (HPV) infections are a leading cause of viral‐induced malignancies worldwide, with a prominent association with cervical and head and neck cancers. The pivotal role of HPV ...oncoproteins, E5, E6, and E7, in manipulating cellular events, which contribute to viral pathogenesis in various ways, has been extensively documented. This article reviews the influence of HPV oncoproteins on cellular signaling pathways within the host cell, shedding light on the underlying molecular mechanisms. A comprehensive understanding of these molecular alterations is essential for the development of targeted therapies and strategies to combat HPV‐induced premalignancies and prevent their progress to cancer. Furthermore, this review underscores the intricate interplay between HPV oncoproteins and some of the most important cellular signaling pathways: Notch, Wnt/β‐catenin, MAPK, JAK/STAT, and PI3K AKT/mTOR. The treatment efficacies of the currently available inhibitors on these pathways in an HPV‐positive context are also discussed. This review also highlights the importance of continued research to advance our knowledge and enhance therapeutic interventions for HPV‐associated diseases.
