Acute kidney injury (AKI) is a global health challenge of vast proportions, as approx. 13.3% of people worldwide are affected annually. The pathophysiology of AKI is very complex, but its main causes ...are sepsis, ischemia, and nephrotoxicity. Nephrotoxicity is mainly associated with the use of drugs. Drug-induced AKI accounts for 19–26% of all hospitalized cases. Drug-induced nephrotoxicity develops according to one of the three mechanisms: (1) proximal tubular injury and acute tubular necrosis (ATN) (a dose-dependent mechanism), where the cause is related to apical contact with drugs or their metabolites, the transport of drugs and their metabolites from the apical surface, and the secretion of drugs from the basolateral surface into the tubular lumen; (2) tubular obstruction by crystals or casts containing drugs and their metabolites (a dose-dependent mechanism); (3) interstitial nephritis induced by drugs and their metabolites (a dose-independent mechanism). In this article, the mechanisms of the individual types of injury will be described. Specific groups of drugs will be linked to specific injuries. Additionally, the risk factors for the development of AKI and the methods for preventing and/or treating the condition will be discussed.
Perinatal hypoxia is a major cause of neurodevelopmental impairment and subsequent motor and cognitive dysfunctions; it is associated with fetal growth restriction and uteroplacental dysfunction ...during pregnancy. This review aims to present the current knowledge on brain development resulting from perinatal asphyxia, including the causes, symptoms, and means of predicting the degree of brain damage. Furthermore, this review discusses the specificity of brain development in the growth-restricted fetus and how it is replicated and studied in animal models. Finally, this review aims at identifying the least understood and missing molecular pathways of abnormal brain development, especially with respect to potential treatment intervention.
Small-for-gestational-age (SGA) are neonates born with birth weight below the 10th centile for a given week of pregnancy. It is a risk factor of perinatal and neonatal morbidity and mortality. There ...is an ongoing debate whether prenatal detection of SGA neonates is good predictor of perinatal outcome especially in low risk populations. Our primary aim was to compare the odds ratios for unfavorable outcome in a risk stratified cohort of SGA neonates in regard to prenatal detection status.
This is a retrospective cohort study analysing the effect of prenatal detection on perinatal outcome. This cohort has been divided into a predefined low-risk and high-risk population. Electronic records of 39,032 singleton deliveries from 2010 through 2016 were analysed. SGA was defined as newborn weight below the 10th percentile on the Fenton growth chart. Detected SGA (dSGA) neonates were those that were admitted for delivery with a prenatal ultrasound diagnosis of abnormal growth. Undetected SGA (uSGA) were neonates that were found to be below the 10th percentile after birth. Perinatal and neonatal outcome was compared.
The detection rate in high-risk pregnancies was almost 45.7% versus low risk where it amounted to 18.9%. In both the high-risk and low-risk populations there was a significantly higher risk of composite mortality for undetected SGA compared to approporiate-for-gestational-age (AGA) (OR 7.95 CI 4.76-13.29; OR 14.4 CI 4.99-41.45 respectively). The odds for the composite neonatal outcome were significantly higher for dSGA and uSGA than for AGA in all the studied populations except for the uSGA in high risk population (OR 1.57 CI 0.97-3.53). Importantly, there was not a single case of intrauterine fetal death among detected SGA, in the low risk group.
Prenatal detection of SGA status is related to perinatal outcomes, especially mortality. Therefore, assessment of SGA status even in low-risk pregnancies could help predict potential perinatal and neonatal complications.

In March 2020, daily life was disrupted by the new virus SARS-CoV-2, which causes COVID-19. Pandemic-related prenatal anxiety could lead to depression, a risk factor for adverse pregnancy outcomes ...and abnormal neonatal development. This study aimed to investigate the impact of anxiety on the mental health of pregnant women exposed to catastrophic events as compared to those without such exposure.
PubMed/MEDLINE, Web of Science, Cochrane Library, Scopus, and EMBASE were searched for relevant studies. This study compared the prevalence of anxiety among pregnant women during a catastrophic event.
Fifteen full texts were assessed for inclusion, with 3 included, 10 excluded for not meeting criteria, and 2 excluded for other reasons. The included studies were published before the current COVID-19 pandemic but included the SARS 2003 outbreak. During the current COVID-19 pandemic, 10 further studies were conducted, but they failed to meet the inclusion criteria. A meta-analysis of two studies using STAI revealed that women exposed to a catastrophic event had a higher mean STAI score of 1.82 points (95% CI: 0.47-3.18 points).
Women with complications during pregnancy should be assessed for anxiety independently from catastrophic events. During financial crises, environmental or other disasters, special attention should be given to women with low risk, normal pregnancies.

This systematic review was conducted to gather evidence of preeclampsia occurring before the 20th week of gestation, additionally considering the role of PLGF and sFlt-1 in the development of the ...disease. In the three cases of preeclampsia before the 20th week of gestation presented in the authors' material, all pregnancies ended up with IUFD, and the SFlt-1/PLGF ratios were significantly elevated in all women. Eligible publications were identified with searches in the PubMed, Embase, Scopus, and Web of Science databases. No date or language restrictions were made. All original peer-reviewed scientific reports were included. A total of 30 publications were included in the final report, including case reports and case series. No other publication types regarding this issue were identified. In the literature, 34 cases of preeclampsia with onset occurring before the 20th week of gestation were identified, for a final total of 37 cases. Live births were reported in 5 cases (10.52%), and there were 9 intrauterine fetal demises (24.32%), and 23 terminations of pregnancy (62.16%). Preeclampsia before the 20th week of gestation is rare but can occur. We collected all available evidence regarding this phenomenon, with 37 cases reported worldwide. We call for large-scale cohort or register-based studies to establish revised definitions or develop new ones regarding the currently unrecognized very early onset preeclampsia.
Abstract
Background
Pelvic girdle pain (PGP) is a type of pregnancy-related lumbopelvic pain. This study aimed to examine the prevalence, severity, and factors associated with postpartum PGP in a ...selected group of postpartum women in Poland.
Methods
This was a prospective, observational study. In phase 1, 411 women were recruited 24–72 h postpartum. The prevalence of PGP was assessed by a physiotherapist using a series of dedicated tests. Pelvic floor muscle function and presence of diastasis recti were assessed via palpation examination. Age, education, parity, mode of delivery, infant body mass, body mass gain during pregnancy, the use of anesthesia during delivery and were recorded. In a phase 2, 6 weeks postpartum, the prevalence of PGP and its severity were assessed via a self-report.
Results
In phase 1 (shortly postpartum), PGP was diagnosed in 9% (n = 37) of women. In phase 2 (6 weeks postpartum), PGP was reported by 15.70% of women (n = 42). The univariable analyses showed a higher likelihood of PGP shortly postpartum in women who declared PGP during pregnancy (OR 14.67, 95% CI 4.43–48.61) and among women with abdominal midline doming (OR 2.05, 95% CI 1.04–4.06). The multivariable regression analysis showed significant associations in women with increased age (OR 1.12, 95% CI 1.01–1.21) and declaring PGP during pregnancy (OR 14.83, 95% CI 4.34–48.72).
Conclusion
Although the prevalence of postpartum PGP among women in Poland is lower than reported in other countries, it is experienced by almost every tenth women shortly postpartum and every sixth can report similar symptoms 6 weeks later. Age, PGP during pregnancy and abdominal midline doming were associated with experiencing PGP shortly postpartum.

Premenstrual dysphoric disorder is a female affective disorder that is defined by mood symptoms. The condition is linked to unstable progesterone concentrations. Progestin supplementation is given in ...cases of threatened or recurrent miscarriage and for luteal phase support. Progesterone is essential for implantation, immune tolerance, and modulation of uterine contractility. For a long time, the administration of progestins was associated with an unfavorable impact on mood, leading to negative affect, and, therefore, was contraindicated in existing mood disorders. Establishing the role of the natural progesterone derivative allopregnanolone in advances in the treatment of postpartum depression has shed new light on the general pathophysiology of mood disorders. Allopregnanolone directly interacts with gamma-aminobutyric acid type A (GABA-A) receptors even at nanomolar concentrations and induces significant anti-depressant, anti-stress, sedative, and anxiolytic effects. Postpartum depression is caused by a rapid drop in hormones and can be instantly reversed by the administration of allopregnanolone. Premenstrual dysphoric disorder can also be considered to result from insufficient neuroactive steroid action due to low progesterone derivative concentration, unstable hormone levels, or decreased receptor sensitivity. The decrease in progesterone levels in perimenopause is also associated with affective symptoms and an exacerbation of some psychosomatic syndromes. Bioidentical progesterone supplementation encounters several obstacles, including limited absorption, first-pass effect, and rapid metabolism. Hence, non-bioidentical progestins with better bioavailability were widely applied. The paradoxical, unfavorable effect of progestins on mood can be explained by the fact that progestins suppress ovulation and disturb the endocrine function of the ovary in the luteal phase. Moreover, their distinct chemical structure prevents their metabolism to neuroactive, mood-improving derivatives. A new understanding of progesterone-related mood disorders can translate the study results from case series and observational studies to cohort studies, clinical trials, and novel, effective treatment protocols being developed.
Obesity is a known factor in the development of preeclampsia. This paper links adipose tissue pathologies with aberrant placental development and the resulting preeclampsia. PPARγ, a transcription ...factor from the ligand-activated nuclear hormone receptor family, appears to be one common aspect of both pathologies. It is the master regulator of adipogenesis in humans. At the same time, its aberrantly low activity has been observed in placental pathologies. Overweight and obesity are very serious health problems worldwide. They have negative effects on the overall mortality rate. Very importantly, they are also conducive to diseases linked to impaired placental development, including preeclampsia. More and more people in Europe are suffering from overweight (35.2%) and obesity (16%) (EUROSTAT 2021 data), some of them young women planning pregnancy. As a result, we will be increasingly encountering obese pregnant women with a considerable risk of placental development disorders, including preeclampsia. An appreciation of the mechanisms shared by these two conditions may assist in their prevention and treatment. Clearly, it should not be forgotten that health education concerning the need for a proper diet and physical activity is of utmost importance here.
Abuse against women in labor starts with subtle forms of discrimination that can turn into overt violence. Therefore it is crucial to work towards prevention and elimination of disrespect and ...ill-treatment in medical facility perinatal care in which staff allows such abuse. The aim of the study was to analyze the experiences of women related to perinatal care. Special emphasis was put on experiences that had traits indicating disrespectful and offensive care during childbirth in medical facilities providing perinatal care.
This was a cross-sectional survey. A questionnaire was prepared for respondents who gave birth in medical facilities. Information about the study was posted on the website of a non-governmental foundation dealing with projects aimed at improving perinatal care. The respondents gave online consent for processing the submitted data. 8378 questionnaires were submitted. The study was carried out between February 06 and March 20, 2018. The results were analyzed using the Chi-square independence test. The analysis was carried out at the significance level of 0.05 in Excel, R and SPSS.
During their hospital stay, 81% of women in the study experienced violence or abuse from medical staff on at least one occasion. The most common abuse was having medical procedures without prior consent. Inappropriate comments made by staff related to their own or a woman's situation were reported in 25% of situations, whilst 20% of women experienced nonchalant treatment. In the study 19.3% of women reported that the staff did not properly care for their intimacy and 1.7% of the respondents said that the worst treatment was related to feeling anonymous in the hospital.
The study shows that during Polish perinatal care women experience disrespectful and abusive care. Most abuse and disrespect involved violation of the right to privacy, the right to information, the right to equal treatment, and the right to freedom from violence. The low awareness of abuses and complaints reported in the study may result from women's ignorance about relevant laws related to human rights.

Background
Vaginal birth is a safe mode of childbirth for the majority of women after cesarean section (CS). However, data show that women who have undergone a CS are more likely to have an elective ...CS (ECS) than a vaginal birth after CS (VBAC) in many areas of the world.
Aim
This study aimed to review the literature about women's mode of birth preferences and attitudes and the underlying reasons for, and factors associated with, their preferences.
Methods
This is narrative literature review. PubMed/MEDLINE and Scopus databases were searched, limiting the results to non‐interventional studies published between 1990 and 2020. Twenty‐one articles were included in the analysis.
Results
The review found 34 different factors that influence women's preferences. Five factors influenced both VBAC and ECS preference, depending on the study. The most common factors having a dualistic effect on preference were: medical staff recommendation, doctor's opinion, and fear of pain. The most common factors were: desire to experience natural childbirth, faster/easier recovery, support from doctor's, and midwife's opinion. Among the factors influencing the preference for ECS, two were particularly prominent: predictability, controllability and comfortability of CS and the belief that CS is safer for the baby and/or mother.
Conclusions
Our review showed that there are a variety of factors that influence women's preference for the mode of delivery after CS. Some of these have a dualistic effect according to the study. The key to making an informed decision regarding the mode of delivery is communication with medical professionals.
