Comparison of endoscopic versus CT assessment of stone-free status after percutaneous nephrolithotomy (PCNL).

This study is aimed to determine whether postoperative low dose computed tomography (LDCT) imaging is necessary after percutaneous nephrolithotomy (PCNL), or the surgeon's intraoperative assessment of residual fragments (RF) is sufficient and avoidance of postoperative imaging with reduction of radiation exposure can be achieved. Data of all 610 patients who underwent PCNL in prone position in our institution from February 2009 to September 2020 was collected. Parameters such as age, gender, BMI, ASA-Classification, stone related parameters and the surgeon's assessment of stone-free status were analyzed. The LDCT performed postoperatively was compared to the intraoperative assessment of the surgeon regarding RF. The mean age of patients was 52.82 years; the mean BMI was 28.18 kg/m2. In 418 cases, the surgeon made a clear statement about the presence of RF and postoperative LDCT was carried out. The discrepancy between the two methods (surgeon´s assessment vs. LDCT) was significant at p < 0.0001. The sensitivity, specificity, positive and negative predictive value of the surgeon when assessing RF were 24.05%, 99.45%, 98.28% and 50%. Stone free rate (SFR) after primary PCNL was 45.57%. The overall SFR at discharge was 96.23%. Although the surgeon´s assessment of RF was reliable, postoperative LDCT imaging should still be performed if endoscopic stone clearance is suspected due to the high false negative rate and the low negative predictive value. The optimal timing of postoperative imaging following PCNL remains unclear.

Evaluation of sexual function and vaginal prolapse after radical cystectomy in women: a study to explore an under-evaluated problem.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate sexual function, vaginal prolapse, and quality of life (QoL) in women after radical cystectomy (RC) using validated questionnaires and pelvic organ prolapse quantification (POP-Q) measurement. METHODS: Female bladder cancer patients who underwent RC at our tertiary care center were included (January 2008 to March 2022). Patients received three validated questionnaires (International Consultation on Incontinence Questionnaire Vaginal Symptoms [ICIQ-VS] Part A, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire IUGA revised [PISQ], European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC] C30/BLM30). Patients who consented were examined with vaginal POP-Q measurement. RESULTS: Out of 322 patients, 193 were still alive, 54 patients were lost to follow-up, and 43 were excluded, resulting in 96 patients who received the questionnaire. Finally, 35 patients were included, of whom 17 patients consented to vaginal examination. Complaints due to vaginal symptoms were low (ICIQ-VS 6.17 + 5.37). Sexual activity was reported by 12 patients (34.3%); 23 patients (65.71%) were not sexually active. No apical prolapse was found in POP-Q measurement; 6 patients (35.3%) had anterior, and 14 patients (82.4%) posterior prolapse; the highest prolapse stage was 2. No significant differences were found regarding POP stages, sexual function, and QoL (all p > 0.05) when comparing continent and incontinent urinary diversions. Comparing the vaginal approach (no sparing vs sparing), significant differences were found in only two PISQ subscales (significantly higher scores after vagina sparing, p = 0.01 and p = 0.02). CONCLUSIONS: The type of urinary diversion, POP-Q stages, and tumor stages did not show significant differences regarding sexual function, QoL, and prolapse complaints in women after RC, whereas a vagina- sparing approach showed significant differences only in two subscales without clinical relevance.

Coping strategies during legally enforced quarantine and their association to psychological distress level: a cross-sectional study.

OBJECTIVES: The non-pharmacological measures to contain the COVID-19 pandemic may lead to considerable psychological distress. The aim of the CoCo-Fakt study was to investigate possible coping strategies and their effects on psychological distress during legally enforced quarantine of infected persons (IPs) and their close contacts (CPs). STUDY DESIGN: This was a cross-sectional cohort study. METHODS: From 12 December 2020 to 6 January 2021, all IPs and their CPs (n = 8232) registered by the public health department (Cologne, Germany) were surveyed online. Psychosocial distress and coping were measured using sum scores; free-text answers related to specific strategies were subsequently categorised. RESULTS: Psychosocial distress was higher in IPs than in CPs (P < .001). Although the mean coping score did not differ between both groups, it was influenced by the reason for quarantine (IP vs CP) besides gender, age, socio-economic status, living situation, psychological distress, resilience, physical activity and eating behaviour. This final regression model explained 25.9% of the variance. Most participants used active coping strategies, such as contact with the social environment, a positive attitude and hobbies. CONCLUSIONS: Although psychological distress was higher in IPs than in CPs during the quarantine period, the mean coping score did not differ. The strategies most frequently used by IPs and CPs were activating social networks, a healthy lifestyle and professional support systems, such as the health department helpline. Appropriate advice should be implemented to prevent long-term psychological consequences when supporting affected people.

Breakthrough infections with the SARS-CoV-2 Delta variant: vaccinations halved transmission risk.

OBJECTIVES: The SARS-CoV-2 Delta variant (B.1.617.2) is associated with increased infectivity. Data on breakthrough SARS-CoV-2 Delta variant infections in vaccinated individuals and transmission risk are limited. The aim of this study was to provide estimates of transmission risk in Delta variant breakthrough infections. STUDY DESIGN: A matched case-control study was performed.. METHODS: To analyse onward transmission of fully vaccinated individuals infected with B.1.617.2, we compared 85 patients (vaccination group [VG]) with an age- and sex-matched unvaccinated control group (CG; n = 85). RESULTS: Transmission of B.1.617.2 was significantly reduced (halved) in the VG. The number of infected contacts to total number of contacts per infected person was 0.26 ± 0.40 in the VG vs 0.56 ± 0.45 in the CG (P = .001). Similarly, fully vaccinated contacts were less likely to be infected by fully vaccinated infected persons (IPs) than by unvaccinated IPs (20.0% vs 37.5%), although this association was not significant. CONCLUSIONS: Fully vaccinated contacts had 50% less transmissions than unvaccinated individuals. These findings must be verified in larger sample populations, and it is especially important to investigate the role of vaccination status of close contacts.

[Participation of people with migration background in health surveys of the Robert Koch Institute]. / Beteiligung von Menschen mit Migrationshintergrund an Gesundheitssurveys des Robert Koch-Instituts.

People with migration background (PMB) make up a huge section of the population with specific health chances and risks. There are only limited data available on the health situation of PMB, since inclusion of PMB in surveys is hindered, e.g. due to language barriers. The present study has examined to what extent the population-based health surveys of the Robert Koch Institute have managed to include a representative extent of PMB, with the aim of deriving recommendations for analysis options and future recruitment strategies. The 2009 microcensus (MC) of the Federal Statistical Office was used as the basis to check whether the sample of KiGGS Wave 1 (2009-2012) and DEGS 1 (2008-2011) are representative regarding socio-demographic and migrant-specific characteristics. 1107 PMB participated in DEGS 1. In comparison to the MC, particular sub-groups are underrepresented in the sample: people who immigrated themselves (first-generation migrants), people with a low education and Turkish citizens. On the other hand, some age groups are overrepresented. In KiGGS Wave 1, 2021 children and adolescents with a migration background participated. Response was lower if parents had a low education. In total, the participation of children and adolescents with a migration background was lower in comparison to the KiGGS baseline survey. The data on PMB in DEGS 1 and KiGGS Wave 1 are appropriate for health analyses of this population group. However, analyses should be stratified according to characteristics like migrant generation, age or education level, or these characteristics should be adjusted for in statistical models. In order to achieve a representative inclusion of people with a migration background, in future surveys sub-group-specific activities to increase participation of PMB are recommended.

Sepsis in second trimester of pregnancy due to an infected myoma. A case report and a review of the literature.

Considering the high incidence of uterine myomata in women in reproductive age, myomata are only found in 2% of all pregnancies. Although they frequently lead to complications in pregnancy, cases of pyomyomata during pregnancy are rarely reported. A 44-year-old gravida 1 in her 26th week of gestation was admitted to the hospital for septic temperatures of unknown cause. A 12-cm leiomyoma with solid structures of heterogenic sonographic pattern and cystic spaces had been documented on a prior first trimester sonogram. The myoma now appeared with the same size but an increased echogenicity of the liquid parts. Ultrasound guided aspiration of the fluid within the myoma showed an infection with Klebsiella pneumoniae. A cesarian section with myo- mectomy confirmed the diagnosis of a pyomyoma.

[The ZEBET database on alternative methods to animal experiments in the Internet--a concrete contribution to the protection of animals]. / Die ZEBET-Datenbank über Alternativen zu Tierversuchen im Internet - ein konkreter Beitrag zum Schutz von Versuchstieren.

Up from February of the year 2000 ZEBET (German Centre for the Documentation and Validation of Alternative Methods) at the Federal Institute for Consumer Health Protection and Veterinary Medicine (BgVV) put the ZEBET-database on alternative methods to animal experiments on the Internet in English via DIMDI, the German Institute for Medical Documentation and Information (http://gripsdb.dimdi.de/engl/guieng.html). The access is free, moreover DIMDI's complete service is available to visitors of the ZEBET-database. The ZEBET database contains documents on alternatives to testing in animals, which have been carefully evaluated by ZEBET's staff according to the "3Rs"-concept established by Russel and Burch in 1959. Therefore, methods documented in the ZEBET database must meet at least one of the following criteria: "replacement" of an animal experiment by a non-animal method, "reduction" of the number of animals used, "refinement" of an experiment by minimising pain and suffering of animals. In addition, the ZEBET-database provides information on the current stage of development and validation of a method and on the acceptance for either scientific or regulatory purposes. Each document is characterised by the following criteria: the title of a method, keywords, assessment, summary and bibliographic references. To search DIMDI<
