The Vicious Circle of Health Security: Vaginal Fistula in Conflict Settings and its Interdependency with Female Oppression

The complex and multilayered interdependence of health and security gets exceedingly obvious in conflict-related sexual violence (CRSV); however, its scientific study is exceptionally invisible. Political unrest increases incidence of gender-based violence (GBV). Rapes, including gang rapes, and forced insertion into the female genitalia of foreign bodies such as bottles, sticks, and weapons can lead to injury of the vagina and the development of traumatic vaginal fistulas (TVF). This paper aims to give structure to the particular characteristics of traumatic vaginal fistula in conflict settings and its immanent linkage to human security. The authors reviewed all papers concerning prevalence and causes of CRSV-caused TVF (CRSV-TVF) that were available on PubMed and GoogleScholar in February 2021. Findings were integrated into feminist theory on CRSV to identify the connecting linkages of security, health, and gender equality. CRSV-caused TVF illustrate well the complex interdependences of health and security: (1) insecurity leads to a higher prevalence of sexual violence; (2) sexual violence can serve as a weapon of war; (3) insecurity prolongs sufficient medical care; (4) vaginal fistula impede female empowerment and societal development. The multiple threads of their connection reveal several implications for the prevention and treatment of TVF. The reciprocal connection of CRSV and security exemplifies a vicious circle of health security

Colon Ascendens Stent Peritonitis (CASP) - a Standardized Model for Polymicrobial Abdominal Sepsis

Sepsis remains a persistent problem on intensive care units all over the world. Understanding the complex mechanisms of sepsis is the precondition for establishing new therapeutic approaches in this field. Therefore, animal models are required that are able to closely mimic the human disease and also sufficiently deal with scientific questions. The Colon Ascendens Stent Peritonitis (CASP) is a highly standardized model for polymicrobial abdominal sepsis in rodents. In this model, a small stent is surgically inserted into the ascending colon of mice or rats leading to a continuous leakage of intestinal bacteria into the peritoneal cavity. The procedure results in peritonitis, systemic bacteraemia, organ infection by gut bacteria, and systemic but also local release of several pro- and anti-inflammatory cytokines. The lethality of CASP can be controlled by the diameter of the inserted stent. A variant of this model, the so-called CASP with intervention (CASPI), raises opportunity to remove the septic focus by a second operation according to common procedures in clinical practice. CASP is an easily learnable and highly reproducible model that closely mimics the clinical course of abdominal sepsis. It leads way to study on questions in several scientific fields e.g. immunology, infectiology, or surgery

Does health securitization affect the role of global surgery?

Aim!#!More and more frequently outbreaks of infectious diseases force the international community to urgent health action and lead to an increasing security focus on global health. Considering the limiting character of resource allocation, all other medical conditions must compete with the top spot of health security matters, as we currently see with the outbreak of COVID-19. Surgery is an integral part of universal health offering life-saving therapy for a variety of illnesses. Amidst the increasing nexus of infectious diseases and health security and in the view of !##!Subject and methods!#!While the global undersupply of surgical care is well recorded, contextual explanations are absent. Our research introduces the constructivist concept of securitization according to the Copenhagen School to explain the structural handicap of global surgery and by that presents a structural explanation. We investigate the securitizing potential of surgical diseases in comparison to infectious diseases.!##!Results!#!Surgical conditions are non-contagious without the risk for disease outbreaks, hardly preventable and their treatment is often infrastructurally demanding. These key features mark their low securitizing potential. Additionally, as !##!Conclusion!#!Surgery substantially lacks securitizing potential in comparison to communicable diseases and by that is structurally given an inferior position in a securitized health order

Narrowing the therapeutic window?—A case-control study on the influence of the COVID-19 pandemic on the primary UICC stage of NSCLC

Background: General clinical perception suggests a decline in the diagnosis and treatment of lung cancer during the SARS-CoV-2 pandemic. Early diagnosis of non-small cell lung cancer (NSCLC) is crucial in therapeutic regimes as early stages are potentially curable by operation alone or with combined therapy. Pandemic-triggered overload of the healthcare system may have prolonged the diagnosis of NSCLC, possibly leading to higher tumor stages at first diagnosis. This study aims to identify how COVID-19 affected the distribution of the Union for International Cancer Control (UICC) stage in NSCLC at first diagnosis. Methods: A retrospective case-control study was conducted, including all patients receiving their first diagnosis of NSCLC in the regions of Leipzig and Mecklenburg-Vorpommern (MV) between January 2019 and March 2021. Patient data were retrieved from the clinical cancer registries of the city of Leipzig and the federal state of MV. Ethical approval for this retrospective evaluation of archived, anonymized patient data was waived by the Scientific Ethical Committee at the Medical Faculty, Leipzig University. Three investigation periods were defined to study the effects of high incidences of SARS-COV-2: the curfew period as an enacted security measure, the period of high incidence rates and the period of the aftermath of high incidences. Differences in the UICC stages between these pandemic periods were studied by Mann-Whitney-U-Test. Pearson’s correlation was calculated to examine changes in operability. Results: The number of patients diagnosed with NSCLC dropped substantially during investigation periods. There was a significant difference in the UICC status in the aftermath of high incidences and imposed security measures in Leipzig (P=0.016). N-status differed significantly in the aftermath of high incidences and imposed security measures (P=0.022) with a decrease of N0- and an increase of N3-status, respectively, while N1- and N2-status remained relatively unaffected. No pandemic phase showed a significant difference in operability. Conclusions: The pandemic led to a delay in the diagnosis of NSCLC in the two examined regions. This resulted in higher UICC stages upon diagnosis. However, no increase in inoperable stages was shown. It remains to be seen, how this will affect the overall prognosis of the involved patients

Pulmonary Metastasising Aneurysmal Fibrous Histiocytoma: A Case Report, Literature Review and Proposal of Standardised Diagnostic Criteria

An aneurysmal fibrous histiocytoma is a rare cutaneous soft-tissue tumour which accounts for approximately 0.06% of all dermatopathologies. Metastasis is exceedingly uncommon, to the point that there have only been eight reported cases in the scientific literature. We present the case of a 25-year-old male with a primary aneurysmal fibrous histiocytoma located in the nuchal region which exhibited rapid growth and abrupt ulceration over a short time span and showed signs of locoregional aggressive infiltration. A subsequent histopathological analysis confirmed the presence of diffuse solid and cystic pulmonary metastases. Further genetic sequencing verified LAMTOR1-PRKCD fusion. This case report seeks to review the existing literature on aneurysmal fibrous histiocytoma, discuss the challenges of differential diagnosis and propose standardised diagnostic criteria

Determination of Mucoadhesion of Polyvinyl Alcohol Films to Human Intestinal Tissue

The absorption of drugs with narrow absorption windows in the upper small intestine can be improved with a mucoadhesive drug delivery system such as enteric films. To predict the mucoadhesive behaviour in vivo, suitable in vitro or ex vivo methods can be performed. In this study, the influence of tissue storage and sampling site on the mucoadhesion of polyvinyl alcohol film to human small intestinal mucosa was investigated. Tissue from twelve human subjects was used to determine adhesion using a tensile strength method. Thawing of tissue frozen at −20 °C resulted in a significantly higher work of adhesion (p = 0.0005) when a low contact force was applied for one minute, whereas the maximum detachment force was not affected. When the contact force and time were increased, no differences were found for thawed tissue compared to fresh tissue. No change in adhesion was observed depending on the sampling location. Initial results from a comparison of adhesion to porcine and human mucosa suggest that the tissues are equivalent

The Role of the Vagus Nerve: Modulation of the Inflammatory Reaction in Murine Polymicrobial Sepsis

The particular importance of the vagus nerve for the pathophysiology of peritonitis becomes more and more apparent. In this work we provide evidence for the vagal modulation of inflammation in the murine model of colon ascendens stent peritonitis (CASP). Vagotomy significantly increases mortality in polymicrobial sepsis. This effect is not accounted for by the dilatation of gastric volume following vagotomy. As the stimulation of cholinergic receptors by nicotine has no therapeutic effect, the lack of nicotine is also not the reason for the reduced survival rate. In fact, increased septic mortality is a consequence of the absent modulating influence of the vagus nerve on the immune system: we detected significantly elevated serum corticosterone levels in vagotomised mice 24 h following CASP and a decreased ex vivo TNF-alpha secretion of Kupffer cells upon stimulation with LPS. In conclusion, the vagus nerve has a modulating influence in polymicrobial sepsis by attenuating the immune dysregulation

The Learning Objective Catalogue for Patient Safety in Undergraduate Medical Education – A Position Statement of the Committee for Patient Safety and Error Management of the German Association for Medical Education

Background: Since the report “To err is human” was published by the Institute of Medicine in the year 2000, topics regarding patient safety and error management are in the focal point of interest of science and politics. Despite international attention, a structured and comprehensive medical education regarding these topics remains to be missing.Goals: The Learning Objective Catalogue for Patient Safety described below the Committee for Patient Safety and Error Management of the German Association for Medical Education (GMA) has aimed to establish a common foundation for the structured implementation of patient safety curricula at the medical faculties in German-speaking countries. Methods: The development the Learning Objective Catalogue resulted via the participation of 13 faculties in two committee meetings, two multi-day workshops, and additional judgments of external specialists.Results: The Committee of Patient Safety and Error Management of GMA developed the present Learning Objective Catalogue for Patient Safety in Undergraduate Medical Education, structured in three chapters: , and . The learning objectives within the chapters are organized on three levels with a hierarchical organization of the topics. Overall, the Learning Objective Catalogue consists of 38 learning objectives. All learning objectives are referenced with the National Competency-based Catalogue of Learning Objectives for Undergraduate Medical Education.Discussion: The Learning Objective Catalogue for Patient Safety in Undergraduate Medical Education is a product that was developed through collaboration of members from 13 medical faculties. In the German-speaking countries, the Learning Objective Catalogue should advance discussion regarding the topics of patient safety and error management and help develop subsequent educational structures. The Learning Objective Catalogue for Patient Safety can serve as a common ground for an intensified, constructive, subject-specific discussion about these topics at the medical faculties, and guide the implementation of hopefully multiple patient safety curricula in undergraduate medical education
