Comment on 'Importance of real-time measurement of sperm head morphology in intracytoplasmic sperm injection' by Fumiaki Itoi et al.

We present a commentary on the article published in the Zygote FirstView: 'Importance of real-time measurement of sperm head morphology in intracytoplasmic sperm injection' by Fumiaki Itoi and colleagues. We comment on the importance of providing the microscope setup details whenever sperm morphology visualization is discussed. The claim of ×6000-10,000 magnification is misleading as such levels of magnification are impossible to achieve.

Preferences of women with low obstetric risk for cesarean or vaginal birth in Poland: Areas for intervention.

BACKGROUND: In Poland, the rate of cesarean birth (CB) is 43%, which is much higher than the European average of 27%. Optimizing the CB birth rate is of critical importance, especially among women with low-risk pregnancies. However, the determinants of cesarean preference among low-risk women in Poland have not been well explored. METHODS: This cross-sectional study included 1011 pregnant women and aimed to identify associations between selected determinants of women's preferences for CB vs. vaginal birth (VB) in Poland. A descriptive questionnaire was distributed online, and a theoretical model was validated against empirically gathered data. Group comparisons were performed using the Welch t test for continuous data or chi-square test for categorical data. All statistical analyses were performed using R (R Core Team, 2018). RESULTS: The mean age of women preferring CB (30.46 years) was 1.25 years higher than that of women preferring VB (29.21 years). Pregnant women who expressed a preference for CB tended to be multigravid, inhabited cities, and were characterized by higher levels of anxiety and depression. Moreover, the majority of women who underwent a previous CB asserted their intention to repeat the procedure for the current pregnancy. CONCLUSIONS: The primary factors that were correlated with high CB preference among the low-risk group included age, previous childbirth experiences, and anxiety. The underlying reasons that drive birth preferences remain poorly understood. However, women who have previously undergone difficult childbirth experiences and are afraid of pain require specialized care.

Factors Associated with Vaginal/Cesarean Birth Attitudes among Medical Students.

BACKGROUND: Polish perinatal care is facing a high, ever-increasing cesarean section (CS) rate that is currently at 43%. Crucially, reports have revealed that the attitudes, experiences, and skills of clinicians directly contribute to this elevated CS rate. METHODS: This cross-sectional study, which included 748 Polish medical students, aimed to identify medical students' attitudes regarding birth methods. A descriptive questionnaire was distributed via the academic email addresses of surveyed medical students. Group comparisons were performed using Welch's t-test for continuous data or a Chi-squared test for categorical data. We also used the Mann-Whitney U test and Kruskal-Wallis H test. RESULTS: Midwifery students (96.2%) were the most unified group of students, with most agreeing that VB (vaginal birth) presents a safer option for women at low risk for VB-related complications vs. cesarean section. Of Medical Faculty students, 68% believed that fewer complications typically occur during vaginal birth than during CS. Students in their final vs. initial years of study furthermore considered VB more beneficial for women than CS. CONCLUSIONS: An important factor identified at the individual clinician level is the presence of leadership and executive support. For medical students, we can interpret this as support from their trainers and supervisors.

IMSI-Guidelines for Sperm Quality Assessment.

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.

Polish Adaptation of the Pregnancy-Related Anxiety Questionnaire-Revised 2 for All Pregnant Women.

Pregnancy-related anxiety (PrA) is a specific type of anxiety characteristic of the perinatal period. PrA can affect pregnancy and birth. However, no validated tool exists to measure PrA in Polish obstetric practice. The aim of this study was to translate the Pregnancy-Related Anxiety Questionnaire-Revised 2 (PRAQ-R2) into Polish and to evaluate its reliability and factorial and construct validity. This study was conducted in Poland as an online questionnaire in April 2020 and included 175 healthy women. To validate the PRAQ-R2, we used standardized tools for the measurement of general anxiety: the modified Visual Analog Scale (VAS), the Ten-Item Personality Inventory (TIPI), and the Hospital Anxiety and Depression Scale (HADS). Scale reliability was assessed using Cronbach's alpha. Concurrent validity was evaluated by calculating Spearman's rho correlation coefficients. Statistical analyses were performed using R ver. 4.0.2. Values for comparative fit index >0.90, Tucker-Lewis index >0.90, and root mean square error of approximation <0.08 indicated acceptable model fit, confirming the reliability of the three-factor structure of the translation. The subscales and total scores had good consistency (α > 0.7), and convergent validity was demonstrated. The PRAQ-R2 as translated into Polish represents the first validated tool in Poland to measure PrA for all pregnant women.

Pain Scales in Neonates Receiving Mechanical Ventilation in Neonatal Intensive Care Units - Systematic Review.

INTRODUCTION: Recently, interest in the problem of proper prevention and monitoring of pain, especially acute, has been increasing in relation to various age groups. Greater awareness of the problem prompts discussion about the purpose of analgesia in newborns treated with mechanical ventilation. AIM: The purpose of the systematic review was to analyze current research on the use of pain scales in newborns treated with mechanical ventilation in the Neonatal Intensive Care Unit. METHODS: Medline databases: PubMed, OVID, EBSCO, Web of Science and Cochrane Library were traced using the appropriate keywords. The search was limited to studies in English. The review took into account the years 2006-2019. Considering the criteria, 12 articles were included in further analysis, to which full access was obtained. RESULTS: The analyzed scientific research showed differences in beliefs about the validity and credibility of the scales used. Researchers indicated that staff with practical experience in using scales in their daily practice was very skeptical of the results obtained on their basis. CONCLUSION: Based on this review, no explicit evidence can be obtained to support the use of one proper scale in pain assessment. It can be inferred that the COMFORT and N-PASS scales are effective for pain assessment and for determining the need for analgesics in mechanically ventilated neonates. These scales may be equally effective in assessing chronic pain, especially in mechanically ventilated children. On the other hand, the PIPP and CRIES scales are most commonly recommended for assessing acute and postoperative pain.

Multicenter study on midwifery students' attitudes towards abortion and it's place in their future practice - Comparison of respondents at early and late stages of the university education.

Evidence based midwifery education and practice are fundamental to assure high quality care of childbearing women, also with complications. In Poland, midwifery education includes aspects of participation in the abortion. A cross-sectional study was designed to describe the attitudes towards abortion at the beginning and at the end of students' university education. The study was aimed to verify change of attitudes throughout the course of the university education. Most of the students approved abortion if the pregnancy constitutes a threat to woman's health or life, results from a rape, or whenever the fetus presents with a lethal defect. More than a half did not approve participation in the abortion if the fetus presents with a non-lethal defect. Generally, the acceptance rates were significantly higher among the final year students, but more than a half of them stated, that the abortion-related topics were inadequately addressed in their study curriculum. That bring to the conclusion that higher rates of abortion acceptance among the final year students, were not necessarily a manifestation of informed approval for this procedure, but rather a form of a "systemic" adjustment. Midwifery program need to be revised to support students in developing informed and evidence-based attitudes toward abortion.

Influence of socio-economic factors on emotional changes during the postnatal period.

OBJECTIVES: The aim of the study was to identify socio-economic factors that may influence the emotional changes which occur among new mothers in the first days postpartum. MATERIAL AND METHODS: A group of 541 women completed a questionnaire consisting of 30 multiple-choice questions, Edinburgh Postnatal Depression Scale (EPDS), and Hospital Anxiety and Depression Scale (HADS). Statistical calculations were performed with the use of Statistica v.10 and Cytel Studio v. 9.0.0. RESULTS: The findings revealed the presence of factors which might increase the risk of mood disorders during the postpartum period. CONCLUSIONS: Women who demonstrate warning symptoms should be screened for postnatal emotional changes and mood swings during their hospitalization after delivery. EPDS seems to be a suitable tool for early detection of emotional disturbances.

[Etiology of acute diarrheas in children from the Lodz region. I. Occurrence of etiologic agents]. / Etiologia ostrych biegunek u dzieci w regionie lódzkim. I. Czestosc wystepowania czynników etiologicznych.

UNLABELLED: The aim of this study was determination of the etiologic agents (bacterial, fungal or viral) of acute diarrheas in children from the Lódz region, suffering from acute diarrhoea during the period from October 1998 to February 2001. Rotaviruses were detected by the latex test. Other microorganisms belonging to the Enterobacteriaceae, Pseudomonadaceae and Vibrionaceae families, as well as the genera Listeria, Campylobacter, Candida, Staphylococcus were cultured on standard or selective culture media according to the NDH recommendations and identification by means of API system. Acute diarrhea in 155 small children below 6 years of age from the Lódz region were caused by rotaviruses (n = 42; 27%). Enteropathogenic strains of Escherichia coli (n = 25; 16.1%) occupied the third place after Salmonella bacteria (n = 30; 19.3%--second place). Among bacterial etiologic factors of diarrhea Campylobacter bacteria showed high frequency of occurrence (n = 22; 14.1%). The investigations enabled identification both the mixed infections (n = 25; 16.1%) and more rare etiologic agents of diarrhea. CONCLUSIONS: 1. Acute diarrhea in children from the region Lódz were most frequently caused by rotaviruses; 2. Modern microbiological diagnostics of acute diarrhea in children should be multilateral, taking account of the mixed infections and expanding the routine search for bacteria of the genus Campylobacter.
