Correlation between pain and depressive symptoms in patients with confirmed endometriosis during COVID-19 pandemic.

BACKGROUND: Endometriosis is a chronic, estrogen-dependent, inflammatory condition which affects women of reproductive age physically and psychologically in their everyday life. The most common symptom is chronic lower abdominal pain. Apart from physical pain, endometriosis often also leads to an unfulfilled desire to give birth. In general, these two main aspects alone lead to emotional stress for patients and often initiate depressive symptoms. To what extent endometriosis patients are additionally affected by the COVID pandemic and its effects is to be determined in this study. METHODS: Patients who presented at our endometriosis center and met the study criteria were offered participation in the study. A link to an online questionnaire (SoSci-Survey) was sent by email. The online questionnaire evaluated depressive symptoms before and during the pandemic as well as the pain perception and perceived support during the pandemic. The data of 167 fully completed questionnaires were evaluated and analyzed using SPSS. RESULTS: The analysis of the questionnaires revealed a significant association between pain levels and depressive symptomatology in endometriosis patients during the pandemic. Patients with more severe pain showed significantly higher depressive symptoms than patients with little or no pain. During the pandemic, patients showed higher depressive symptoms than before. In addition, it was found that those endometriosis patients who felt left alone with their pain due to the consequences of the COVID pandemic, or who felt they had to endure the pain alone, also had higher depressive symptoms. CONCLUSION: In summary, it can be observed that endometriosis patients with a high pain burden had significantly higher depressive symptoms during the COVID pandemic. The consequences of the pandemic often led to the feeling of having to cope with the symptoms alone or having to endure pain alone, which in turn increased the depressive symptoms. As treating physicians, we should be aware of these connections and try to counteract them with targeted offers and support.

COVID-19 Vaccination during Pregnancy and Lactation: Attitudes and Uptakes before and after Official Recommendations in Germany.

BACKGROUND: Vaccination against COVID-19 is an effective measure to mitigate the pandemic. Pregnant and breastfeeding women were not included in registration studies, so official recommendations to vaccinate this vulnerable group appeared belated. Therefore, our aims were to evaluate vaccination uptake, reasons for and against vaccination, and the changes in these depending on the official national recommendations in Germany. METHODS: An anonymous online cross-sectional survey among pregnant and breastfeeding women was conducted prior to and after the publication of the official vaccination recommendation. RESULTS: Data from the convenience sample of 5411 participants (42.9% pregnant; 57% breastfeeding) were analysed. The recommendation was known to 95% of the participants. The information was obtained mainly autonomously (61.6%) and through the media (56.9%). Vaccination uptake increased in pregnant (2.4% before vs. 58.7% after) and breastfeeding women (13.7% vs. 74.7%). As reasons to get vaccinated, pregnant women indicated more fear of the infection than of the side effects of vaccination (52.0% before vs. 66.2% after), intended protection of the baby and oneself (36.0% vs. 62.9%), and limited information about vaccination (53.5% vs. 24.4%). CONCLUSION: The official national recommendation is widely known and mostly obtained autonomously, thereby showing a high level of awareness and a rise in vaccination uptake. Nonetheless, targeted education campaigns focusing on scientific evidence should be maintained, whereas the engagement of health professionals should be enhanced.

The influence of being pregnant during the COVID-19 pandemic on birth expectations and antenatal bonding.

PURPOSE: The aim of the present study was to compare birth expectations and antenatal bonding of women pregnant prior to and during the COVID-19 pandemic. MATERIALS AND METHODS: In total, 74 pregnant women (mean age: 33.9 ± 4.1 years, gestational age: 36 ± 2 weeks) participated in the study, who were pregnant either during the the COVID-19 pandemic (corona group, N = 35, April-July 2020) or before the pandemic (control group, N = 39, October 2017-January 2019). Birth expectations were measured using the Wijma Delivery Expectancy Questionnaire (WDEQ) and Salmon's Item List (SIL) and antenatal bonding with the Maternal Antenatal Attachment Scale (MAAS). Additionally, the corona group indicated their level of worry regarding different pandemic-related aspects using visual analogue scales. RESULTS: The corona group displayed significantly elevated fear of childbirth measured by the WDEQ and lower antenatal bonding quality compared to the control group. The additional items regarding COVID-19 burdens highlighted that the aspects that the partner may not be present during labour and that no visitors will be allowed in hospital were associated with the highest worries. CONCLUSIONS: Midwives and gynaecologists should be aware of the negative impact of the COVID-19 pandemic on fear of childbirth and antenatal bonding .

Does Nutrition Affect Endometriosis?

Endometriosis is a hormone-related, chronic inflammation in women of childbearing age. The aetiology and pathogenesis of endometriosis are not yet fully understood. For other illnesses classed as lifestyle diseases, the link between nutrition and pathogenesis has already been researched and proven. With regard to these findings, the question continues to arise as to whether and how a specific diet and lifestyle could also influence pathogenesis and the progression of endometriosis. The aim of this review is to examine the data and determine what influence nutrition has on the development of endometriosis or on existing disease. The study results currently available do not permit a clear, scientific recommendation or indicate a detailed diet. In summary, it can be said that fish oil capsules in combination with vitamin B 12 have been associated with a positive effect on endometriosis symptoms (particularly of dysmenorrhoea). Alcohol and increased consumption of red meat and trans fats are associated with a negative effect. The results of the studies listed with regard to fruit and vegetables, dairy products, unsaturated fats, fibre, soy products and coffee are not clear. Therefore, the general recommendations for a balanced and varied diet in line with the guidelines of the Deutsche Gesellschaft für Ernährung e. V. [German Nutrition Society] apply, along with the recommendation to cut out alcohol. In order to be able to derive more concrete recommendations, we require further studies to investigate the influence of nutrition on endometriosis.

The Influence of Personality and Anxiety Traits on Birth Experience and Epidural Use in Vaginal Deliveries - A Cohort Study.

A positive birth experience for the mother is an important goal in obstetric health care and is influenced by several factors. For this study, 186 women filled in questionnaires between 24 and 72 hours after giving birth vaginally. We evaluated the Big-Five personality traits (extraversion, neuroticism, openness, conscientiousness and agreeableness), trait anxiety, different dimensions of childbirth experience and pain management. Correlation analysis revealed that trait anxiety and neuroticism were negatively associated with several dimensions of the birth experience. Furthermore, conscientiousness and extraversion were positively correlated with the dimension Participation. Regression analysis for the individual dimensions and overall score respectively, confirmed the independent impact of anxiety trait on Perceived Safety, Participation and Professional Support and the overall score as well as of neuroticism on Perceived Safety and conscientiousness on Participation. The significant regression models showed small R2-scores (.084-.154). The birth experience did not differ whether the women received an epidural or not. Women who did not receive an epidural displayed higher scores on the personality trait conscientiousness. The study highlights small but important associations between personality traits and birth experience in vaginal births which should sensitize the medical staff when supporting women during labor.

Both interferon alpha and lambda can reduce all intrahepatic HDV infection markers in HBV/HDV infected humanized mice.

Co-infection with hepatitis B (HBV) and D virus (HDV) is associated with the most severe course of liver disease. Interferon represents the only treatment currently approved. However, knowledge about the impact of interferons on HDV in human hepatocytes is scant. Aim was to assess the effect of pegylated interferon alpha (peg-IFNα) and lambda (peg-IFNλ), compared to the HBV-polymerase inhibitor entecavir (ETV) on all HDV infection markers using human liver chimeric mice and novel HDV strand-specific qRT-PCR and RNA in situ hybridization assays, which enable intrahepatic detection of HDV RNA species. Peg-IFNα and peg-IFNλ reduced HDV viremia (1.4 log and 1.2 log, respectively) and serum HBsAg levels (0.9-log and 0.4-log, respectively). Intrahepatic quantification of genomic and antigenomic HDV RNAs revealed a median ratio of 22:1 in untreated mice, resembling levels determined in HBV/HDV infected patients. Both IFNs greatly reduced intrahepatic levels of genomic and antigenomic HDV RNA, increasing the amounts of HDAg- and antigenomic RNA-negative hepatocytes. ETV-mediated suppression of HBV replication (2.1-log) did not significantly affect HBsAg levels, HDV productivity and/or release. In humanized mice lacking adaptive immunity, IFNs but not ETV suppressed HDV. Viremia decrease reflected the intrahepatic reduction of all HDV markers, including the antigenomic template, suggesting that intracellular HDV clearance is achievable.

Hepatitis Delta co-infection in humanized mice leads to pronounced induction of innate immune responses in comparison to HBV mono-infection.

BACKGROUND & AIMS: The limited availability of hepatitis Delta virus (HDV) infection models has hindered studies of interactions between HDV and infected hepatocytes. The aim was to investigate the antiviral state of HDV infected human hepatocytes in the setting of co-infection with hepatitis B virus (HBV) compared to HBV mono-infection using human liver chimeric mice. METHODS: Viral loads, human interferon stimulated genes (hISGs) and cytokines were determined in humanized uPA/SCID/beige (USB) mice by qRT-PCR, ELISA and immunofluorescence. RESULTS: Upon HBV/HDV inoculation, all mice developed viremia, which was accompanied by a significant induction of hISGs (i.e. hISG15, hSTATs, hHLA-E) compared to uninfected mice, while HBV mono-infection led to weaker hISG elevations. In the setting of chronic infection enhancement of innate defense mechanisms was significantly more prominent in HBV/HDV infected mice. Also the induction of human-specific cytokines (hIP10, hTGF-ß, hIFN-ß and hIFN-λ) was detected in HBV/HDV co-infected animals, while levels remained lower or below detection in uninfected and HBV mono-infected mice. Moreover, despite the average increase of hSTAT levels determined in HBV/HDV infected livers, we observed a weaker hSTAT accumulation in nuclei of hepatocytes displaying very high HDAg levels, suggesting that HDAg may in part limit hSTAT signaling. CONCLUSIONS: Establishment of HDV infection provoked a clear enhancement of the antiviral state of the human hepatocytes in chimeric mice. Elevated pre-treatment ISG and interferon levels may directly contribute to inflammation and liver damage, providing a rationale for the more severe course of HDV-associated liver disease. Such antiviral state induction might also contribute to the lower levels of HBV activity frequently found in co-infected hepatocytes.

Persistent hepatitis D virus mono-infection in humanized mice is efficiently converted by hepatitis B virus to a productive co-infection.

BACKGROUND & AIMS: Clinical studies have shown that hepatitis delta virus (HDV) infection can persist for years and intrahepatic latency of the large delta antigen (HDAg) has been detected following liver transplantation. However, large HDAg arising via RNA-editing is associated with increasing amounts of non-infectious HDV quasi-species. This study investigated whether HDV could persist intrahepatically in the absence of HBV in vivo and whether infectious HDV could subsequently be released following HBV super-infection. METHODS: Humanized mice were infected with HDV particles lacking HBV. To test for rescue of latent HDV infection 3 and 6 weeks HDV mono-infected mice were super-infected with HBV. Viral loads and cell toxicity were determined by qRT-PCR and immunohistochemistry. RESULTS: The presence of HDAg-positive human hepatocytes determined after 2, 3, and 6 weeks of HDV inoculation demonstrated establishment and maintenance of intrahepatic HDV mono-infection. Although intrahepatic amounts of large HDAg and edited HDV RNA forms increased over time in HDV mono-infected livers, HBV super-infection led to prompt viremia development (up to 10(8) HDV RNA and 10(7) HBV-DNA copies/ml) even after 6 weeks of latent mono-infection. Concurrently, the number of HDAg-positive human hepatocytes increased, demonstrating intrahepatic HDV spreading. The infectivity of the rescued HDV virions was verified by serial passage in naive chimeric mice. CONCLUSIONS: HDV mono-infection can persist intrahepatically for at least 6 weeks before being rescued by HBV. Conversion of a latent HDV infection to a productive HBV/HDV co-infection may contribute to HDV persistence even in patients with low HBV replication and in the setting of liver transplantation.

Humanized chimeric uPA mouse model for the study of hepatitis B and D virus interactions and preclinical drug evaluation.

UNLABELLED: No specific drugs are currently available against hepatitis delta virus (HDV), a defective virus leading to the most severe form of chronic viral hepatitis in man. The lack of convenient HDV infection models has hampered the development of effective therapeutics. In this study, naïve and hepatitis B virus (HBV) chronically infected humanized uPA/SCID mice were employed to establish a small animal model of HBV/HDV coinfection and superinfection. For preclinical antiviral drug evaluation, the GMP version of the myristoylated preS-peptide (Myrcludex-B), a lipopeptide derived from the pre-S1 domain of the HBV envelope, was applied to prevent de novo HBV/HDV coinfection in vivo. Virological parameters were determined at serological and intrahepatic level both by real-time polymerase chain reaction (PCR) and by immunohistochemistry. Establishment of HDV infection was highly efficient in both HBV-infected and naïve chimeric mice with HDV titers rising up to 1 × 10E9 copies/mL. Notably, HDV superinfection led to a median 0.6log reduction of HBV viremia, which although not statistically significant suggests that HDV may hinder HBV replication. In the setting of HBV/HDV simultaneous infection, a majority of human hepatocytes stained HDAg-positive long before HBV spreading was completed, confirming that HDV can replicate intrahepatically also in the absence of HBV infection. Furthermore, the increase of HBV viremia and intrahepatic cccDNA loads was significantly slower than in HBV mono-infected mice. Treatment with the HBV entry inhibitor Myrcludex-B, efficiently hindered the establishment of HDV infection in vivo. CONCLUSION: We established an efficient model of HBV/HDV infection to exploit mechanisms of viral interference in human hepatocytes and to test the efficacy of an HDV-entry inhibitor in vivo.
