RESUMO

Overactive bladder syndrome (OAB) is a prevalent condition that affects the elderly population in particular and significantly impairs quality of life. Imperatorin, a naturally occurring furocoumarin, possesses diverse pharmacological properties that warrant consideration for drug development. The aim of this study was to investigate the potential of imperatorin (IMP) to attenuate the cystometric and biochemical changes typically associated with retinyl acetate-induced overactive bladder (OAB) and to assess its viability as a pharmacological intervention for OAB patients. A total of 60 rats were divided into four groups: I-control, II-rats with rapamycin (RA)-induced OAB, III-rats administered IMP at a dose of 10 mg/kg/day, and IV-rats with RA-induced OAB treated with IMP. IMP or vehicle were injected intraperitoneally for 14 days. The cystometry and assessment of bladder blood flow were performed two days after the last dose of IMP. The rats were then placed in metabolic cages for 24 h. Urothelial thickness measurements and biochemical analyses were performed. Intravesical infusion of RA induced OAB. Notably, intraperitoneal administration of imperatorin had no discernible effect on urinary bladder function and micturition cycles in normal rats. IMP attenuated the severity of RA-induced OAB. RA induced increases in urothelial ATP, calcitonin gene-related peptide (CGRP), organic cation transporter 3 (OCT3), and vesicular acetylcholine transporter (VAChT), as well as significant c-Fos expression in all micturition areas analyzed, which were attenuated by IMP. Furthermore, elevated levels of Rho kinase (ROCK1) and VAChT were observed in the detrusor, which were reversed by IMP in the context of RA-induced OAB in the urothelium, detrusor muscle, and urine. Imperatorin has a mitigating effect on detrusor overactivity. The mechanisms of action of IMP in the bladder appear to be diverse and complex. These findings suggest that IMP may provide protection against RA-induced OAB and could potentially develop into an innovative therapeutic strategy for the treatment of OAB.

RESUMO

The aim of this study was to assess the quality of life (QoL) of men treated for infertility in Poland. This cross-sectional study was conducted using the Abbreviated World Health Organization Quality of Life questionnaire (WHOQoL-BREF), Fertility Quality of Life tool (FertiQoL) and an author-constructed questionnaire. The study included 1200 men treated for infertility without the use of assisted reproductive technology (non-ART), intrauterine insemination (IUI) and in vitro fertilization (IVF). The control group consisted of 100 healthy men with confirmed fertility. The quality of life assessed by the WHOQoL-BREF questionnaire was significantly lower in study groups in the Environmental domain, compared to the control group (p = 0.009). Statistically significant differences were found in the case of FertiQoL subscales: Emotional, Mind-Body, Relational, and Treatment Environment, depending on applied treatment. Men whose partners were treated without the use of ART assessed their QoL significantly more negatively than those treated with IUI. Reproductive problems and type of their treatment influenced the quality of life of the affected men. Non-ART treatment, rural place of residence, and increased BMI were associated with lower QoL.

RESUMO

Intracytoplasmic sperm injection (ICSI) is a widely used and accepted treatment of choice for oocyte fertilization. However, the quality of sperm selection depends on the accurate visualization of the morphology, which can be achieved with a high image resolution. We aim to correct the conviction, shown in a myriad of publications, that an ultra-high magnification in the range of 6000×-10,000× can be achieved with an optical microscope. The goal of observing sperm under the microscope is not to simply get a larger image, but rather to obtain more detail-therefore, we indicate that the optical system's resolution is what should be primarily considered. We provide specific microscope system setup recommendations sufficient for most clinical cases that are based on our experience showing that the optical resolution of 0.5 µm allows appropriate visualization of sperm defects. Last but not least, we suggest that mixed research results regarding the clinical value of IMSI, comparing to ICSI, can stem from a lack of standardization of microscopy techniques used for both ICSI and IMSI.

RESUMO

Background: The purpose of the study was to assess the level of such psychosocial resilience resources as self-efficacy, dispositional optimism, and health locus of control in pregnant women with obesity with threatened premature labor. Methods: The study was performed in the years 2017-2020 in a group of 328 pregnant women hospitalized due to threatened preterm labor and diagnosed with obesity before the pregnancy. The following instruments were applied: the Life Orientation Test, the Generalized Self-Efficacy Scale, and the Multidimensional Health Locus of Control Scale. Results: Obese pregnant women with threatened premature labor have a moderate level of generalized self-efficacy (28.02) and a moderate level of dispositional optimism (16.20). Out of the three health locus of control dimensions, the highest scores were recorded in the "internal control" subscale (26.08). Statistically significant predictors for the self-efficacy variable model included: satisfactory socio-economic standing (ß = 0.156; p = 0.004), being nulliparous (ß = -0.191; p = 0.002), and the absence of comorbidities (ß = -0.145; p = 0.008). Higher levels of dispositional optimism were found in women who were married (ß = 0.381; p = 0.000), reported a satisfactory socio-economic standing (ß = 0.137; p = 0.005), were between 23 and 27 weeks pregnant (ß = -0.231; p = 0.000), and had no comorbidities (ß = -0.129; p = 0.009). Conclusions: Generalized self-efficacy in obese women with threatened preterm labor is associated with satisfactory socio-economic standing, being nulliparous, and the absence of chronic disease. Dispositional optimism in obese pregnant women with threatened preterm labor is determined by their marital status, socio-economic standing, gestational age, and the absence of comorbidities.

RESUMO

The aim of this study was to assess the quality of life (QoL) of infertility treated women as it can affect the effectiveness of therapy. This cross-sectional study was conducted with Abbreviated World Health Organization Quality of Life questionnaire (WHOQOL-BREF), Fertility Quality of Life tool (FertiQoL) and an author's questionnaire. The study included 1200 women treated for infertility without the use of assisted reproductive technology (non-ART), intrauterine insemination (IUI), or in vitro fertilization (IVF). The control group was 100 healthy women who had children. The time to conceive did not significantly differ between study groups and was 3.1-3.6 years, on average. The quality of life in the WHOQOL-BREF questionnaire data significantly differed between study groups and the control (physical domain p < 0.001, psychological p = 0.009; social p = 0.004; environmental p < 0.001). A significant effect was found in 4 FertiQoL subscales: emotional, biological, partnership, and attitude towards treatment; depending on the method of treatment. Women who received non-ART treatment evaluated their QoL in significantly more negative terms in these 4 subscales, compared to those treated with IVF. The quality of life depends on reproductive problems, methods of infertility treatment, age, place of residence, and education level. Prolongation of the duration of treatment unfavourably affects the quality of life. The quality of life of women undergoing infertility treatment differs according to the mode of work and having children from a previous relationship.
