RESUMO
BACKGROUND: Available data identify pregnancy as a strong determinant of a severe course of COVID-19 with increased mortality. Extracorporeal membrane oxygenation (ECMO) remains the last resort treatment in the critical course of COVID-19 yet may increase the risk of excessive bleeding, especially in the immediate post-cesarean section period. One in five patients receiving ECMO during the COVID-19 pandemic were women who were pregnant or postpartum. While the risk of critical respiratory failure in the peripartum period is high, in an early survey only 52% of pregnant patients intended to receive the COVID-19 vaccine. METHODS: Our study aimed to evaluate clinical characteristics and treatment modalities in a series of five pregnant and peripartum women supported with ECMO and anticoagulated with anti-Xa-guided nadroparin therapy in our center. We reviewed the full treatment courses; inflammatory, hemodynamic, and coagulation variables; and maternal and neonatal outcomes. We identified adverse events during the therapy. RESULTS: All five patients developed acute respiratory distress syndrome due to COVID-19 in the third trimester of pregnancy. Termination of pregnancy occurred between 28 and 36 gestational weeks. While four of five newborns survived to hospital discharge, only two of the five mothers survived to leave hospital. CONCLUSIONS: ECMO is feasible in the third trimester but not devoid of complications. The severity of respiratory failure during COVID-19 and extracorporeal support may not adversely impact neonatal outcomes.

PURPOSE: The aim of the study was to evaluate the frequency of occurrence of HPV and co-infection: Chlamydia (C.) trachomatis and HSV-2 in cervical cancer. MATERIAL AND METHODS: The study group consisted of 570 paraffin-sectioned samples of patients with cervical cancer. In order to identify viral and bacterial DNA in DNA isolated from archival, postoperative material, PCR analysis was performed using starters complementary to various types of HPV, HSV-2 and C. trachomatis. RESULTS: In patients with squamous cell cervical cancer the presence of 33 types of HPV was found in 90% (468/520). HPV 16 infections occurred in 69.4% (325/468), while HPV 18 infections were present in 30.5% (143/468) of cases. In the control group C. trachomatis and HSV-2 were observed in four cases (4/50), which constitute 8.0%. In the tissue sections from patients with squamous cell cervical carcinoma, C. trachomatis was identified in 26% (135/520) and HSV-2 in 28% (145/520). In the group of patients with adenocarcinoma C. trachomatis infections were found in 24% (12/50) and herpes virus was identified in 30% (15/50). Statistically significantly higher frequency of occurrence of HSV-2 and C. trachomatis was observed in paraffin-sectioned samples for patients with invasive cervical cancer compared to the control group, without neoplastic lesions (p < 0.05). No correlation was found between frequency of occurrence of HPV and C. trachomatis and of HPV and HSV-2 detected in paraffin-sectioned samples for cervical carcinoma.

Cyclo-oxygenase (COX), which catalyses the conversion of arachidonic acid to prostaglandin endoperoxide and prostanoids, is widely expressed in mammalian organs. The aim of the study was to evaluate the immunoexpression of the constitutive and inducible cyclo-oxygenase isoforms (COX-1 and COX-2 respectively) in the oesophagus, stomach and the small and large bowels of untreated rat dams and foetuses on gestational day 21. The localisation of the COX isoforms was similar in the maternal and foetal organs, although the intensity of the reaction for COX-2 was stronger in the foetuses. Cytoplasmic COX-1 immunostaining was found in myocytes of the muscularis propria, muscularis mucosae and the blood vessels. It was also positive in the endothelial cells, scattered stromal cells of the lamina propria and the ganglion cells of the nerve plexus in the bowels. Apart from the keratinised layer, a strong reaction was revealed in the stratified squamous epithelium of the oesophagus and forestomach. Negative or weakly positive staining was found in the mucus-secreting cells covering the surface, gastric pits and pyloric glands, as well as in the parietal cells and the chief cells. Weakly positive COX-1 immunostaining was observed in epithelial cells of the small intestine crypts, but in some cases enterocytes and goblet cells covering villi were also positive. In the colonic mucosa weak COX-1 staining was typical of the absorptive, and goblet cells. The COX-2 immunostaining was nuclear and/or cytoplasmic. An inconsistent positive reaction was seen in the muscle of the muscularis mucosae, muscularis propria and the blood vessels. Positive staining was also found in scattered stromal cells of the lamina propria and adventitia and the ganglion cells. Weak nuclear staining was found in the stratified squamous epithelium of the oesophagus and forestomach. Unlike the strong foetal reactivity in the epithelial cells of the glandular stomach, a negative or weakly positive reaction was seen in the maternal parietal and/or mucous-secreting surface stomach cells. Some epithelial cells of the crypts both in the small and large bowel were also COX-2 positive. In conclusion, constitutive and inducible COX isoforms were detected in the digestive tract of pregnant female and in foetuses. COX-1 was the predominant isoform in both the adult and foetal organs.

In recent years, more scholarly attention has been paid to a growing range of geographic characteristics as antecedents of inequalities in women's health and well-being. The purpose of this study was to evaluate differences in health-related quality of life between rural and urban Polish postmenopausal women. Using a data set from a reproductive health preventive screening of 660 postmenopausal women aged 48-60 years, inhabitants of Wielkopolska and Lublin provinces, the association of place of residence, socioeconomic status and lifestyle factors with health-related quality of life (the SF-36 instrument) was evaluated using ANCOVA models and multiple logistic regression analysis with backward elimination steps. A consistent rural-to-urban gradient was found in all indices of physical health functioning and well-being but not in vitality, social functioning, emotional role and mental health scales with women in large cities being likely to enjoy the highest and those in villages the lowest quality of life. The rural-urban disparities in health-related quality of life were mediated by women's socioeconomic status. The likelihood of worse physical and mental functioning and well-being was 2-3 times greater for the low socioeconomic status rural women than their counterparts from more affluent urban areas. The educational attainment and employment status were the most powerful independent risk factors for health-related quality of life in both rural and urban women. Better understanding of the role of socioeconomic status that acts as a mediator in the association between area of residence and health-related quality of life may be useful in developing public health policies on health inequalities among women at midlife.

Introduction. The aim of the study was to define the prevalence of bleeding events in patients treated with dual antiplatelet therapy (DAT) in comparison with patients receiving only acetylsalicylic acid (ASA).Methods. Prospective two-centre registry of all first implantations of pacemakers, cardioverter-defibrillators and cardiac resynchronisation therapy units in patients receiving ASA (n=194) or DAT (n=53).Results. Bleeding complications were detected in 27 (16.2%) patients in the ASA group and in 13 (24.5%) in the DAT group. There was no significant difference in the overall number of complications between the patients receiving ASA or DAT, although there was a trend towards a higher incidence of overall complication rates in the DAT group (p=0.0637). The incidence of major complications (requiring blood transfusion or surgical intervention or prolonging hospital stay) was low (3.6%), and similar in both groups (3.6 and 3.8% respectively, ns). The rate of minor complications (subcutaneous haematomas) was greater in the DAT group (p=0.015).Conclusions. Treatment with DAT does not increase the risk of major bleeding complications as a result of device implantation; however, minor complications are significantly more frequent. Our results suggest that DAT could be continued in patients undergoing device implantation with a moderate risk of bleeding complications. (Neth Heart J 2010;18:230-5.).
