Tiza-Titre increase and enhanced immunity through an adjuvanted, recombinant herpes zoster subunit vaccine in patients with liver cirrhosis and post-liver transplantation: a study protocol for a prospective cohort study.

INTRODUCTION: Shingrix, an effective adjuvanted, recombinant herpes zoster vaccine (RZV), has been available since 2018. Immunocompromised patients are known to be predisposed to vaccine failure. In-vitro testing of immunological surrogates of vaccine protection could be instrumental for monitoring vaccination success. So far, no test procedure is available for vaccine responses to RZV that could be used on a routine basis. METHODS AND ANALYSIS: This is a single-centre, three-arm, parallel, longitudinal cohort study aspiring to recruit a total of 308 patients (103 with a liver cirrhosis Child A/B, 103 after liver transplantation (both ≥50 years), 102 immunocompetent patients (60-70 years)). Blood samples will be taken at seven data collection points to determine varicella zoster virus (VZV) and glycoprotein E (gE)-specific IgG and T cell responses. The primary study outcome is to measure and compare responses after vaccination with RZV depending on the type and degree of immunosuppression using gE-specific antibody detection assays. As a secondary outcome, first, the gE-specific CD4+ T cell response of the three cohorts will be compared and, second, the gE-VZV antibody levels will be compared with the severity of possible vaccination reactions. The tertiary outcome is a potential association between VZV immune responses and clinical protection against shingles. ETHICS AND DISSEMINATION: Ethical approval was issued on 07/11/2022 by the Ethics Committee Essen, Germany (number 22-10805-BO). Findings will be published in peer-reviewed open-access journals and presented at local, national and international conferences. TRIAL REGISTRATION NUMBER: German Clinical Trials Registry (number DRKS00030683).

cfDNA as a surrogate marker for COVID-19 severity in patients with influenza-like symptoms with and without SARS-CoV-2 infections in general practice: a study protocol for a prospective cohort study.

INTRODUCTION: The clinical course of patients with a SARS-CoV-2 (COVID-19) infection varies widely, from symptom-free to severe courses that can lead to death. Laboratory values of SARS-CoV-2 patients such as lymphocyte counts or C-reactive protein (CRP) do not allow a prediction of the actual course of the disease. To identify a possible predictive marker for the differentiation and prognosis of illness with influenza-like symptoms with and without SARS-CoV-2 infections in general practice, we will analyse the concentrations of cell-free DNA (cfDNA) levels, laboratory and clinical parameters, temperature, oxygen saturation, breathing rate and concomitant symptoms in patients with flu-like symptoms with and without a SARS-CoV-2 infection. METHODS AND ANALYSIS: This is a single-centre, two-arm, parallel longitudinal cohort study with a total of 44 patients. 22 patients with flu-like symptoms without a SARS-CoV-2 infection and 22 patients with flu-like symptoms with a SARS-CoV-2 infection will be recruited. The primary objective is to compare cfDNA levels in ambulatory patients in general practice with flu-like symptoms with SARS-CoV-2 infection with those with influenza like symptoms without a SARS-CoV-2 infection during the disease (day 7 and day 14). The secondary objective is to determine whether there is a correlation between cfDNA concentrations on the one hand, and laboratory and clinical parameters on the other hand. cfDNA, differential blood count, high-sensitive CRP and erythrocyte sedimentation rate will be measured in blood samples, concomitant symptoms will be surveyed via a self-assessment questionnaire, and oxygen saturation, breathing rate and examination of the lungs will be reported by treating physicians. ETHICS AND DISSEMINATION: Ethical approval was issued on 1 March 2021 by the Ethics Committee Essen under the number 21-9916-BO. Findings will be published in peer-reviewed open-access journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER: DRKS00024722.

The influence of excessive consumption of liquorice on phenprocoumon (Marcumar®): a case report.

Here, the case of a 92-year-old female patient, who was diagnosed with atrial fibrillation and treated with phenprocoumon (Marcumar®), is reported. Pre-existing comorbidities were arterial hypertension, coronary heart disease, diabetes mellitus type 2, mild senile dementia and renal insufficiency. Despite treatment with phenprocoumon (Marcumar®), the patient experienced an ischaemic stroke. Her measured international normalized ratio (INR)-values during the months before the stroke were within the therapeutic range of 2-3, then suddenly decreased to 1.25. A retrospective inquiry failed to identify any significant changes in behaviour or therapy adherence, other than the consumption of 1.5 kg (3.3 lb) of hard-boiled candy liquorice in the days leading up to the stroke. The sudden decrease in INR-values may be explained by the influence of liquorice and its compounds on the pharmacokinetics of phenprocoumon (Marcumar®). In this context, the most important factors are the susceptibility of vitamin K antagonists to nutrition or metabolic irregularities, the influence of liquorice on the function of isoenzymes of the cytochrome P450 family that may lead to reduced bioavailability of phenprocoumon, and the influence of liquorice on peroxisome proliferator-activated receptor alpha transactivation.

A pragmatic randomised controlled trial referring to a Personalised Self-management SUPport Programme (P-SUP) for persons enrolled in a disease management programme for type 2 diabetes mellitus and/or for coronary heart disease.

BACKGROUND: Type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD) are two chronic diseases that cause a tremendous burden. To reduce this burden, several programmes for optimising the care for these diseases have been developed. In Germany, so-called disease management programmes (DMPs), which combine components of Disease Management and the Chronic Care Model, are applied. These DMPs have proven effective. Nevertheless, there are opportunities for improvement. Current DMPs rarely address self-management of the disease, make no use of peer support, and provide no special assistance for persons with low health literacy and/or low patient activation. The study protocol presented here is for the evaluation of a programme that addresses these possible shortcomings and can be combined with current German DMPs for T2DM and CHD. This programme consists of four components: 1) Meetings of peer support groups 2) Personalised telephone-based health coaching for patients with low literacy and/or low patient activation 3) Personalised patient feedback 4) A browser-based web portal METHODS: Study participants will be adults enrolled in a DMP for T2DM and/or CHD and living in North Rhine-Westphalia, a state of the Federal Republic of Germany. Study participants will be recruited with the assistance of their general practitioners by the end of June 2021. Evaluation will be performed as a pragmatic randomised controlled trial with one intervention group and one waiting control group. The intervention group will receive the intervention for 18 months. During this time, the waiting control group will continue with usual care and the usual measures of their DMPs. After 18 months, the waiting control group will also receive a shortened intervention. The primary outcome is number of hospital days. In addition, the effects on self-reported health-state, physical activity, nutrition, and eight different psychological variables will be investigated. Differences between values at month 18 and at the beginning will be compared to judge the effectiveness of the intervention. DISCUSSION: If the intervention proves effective, it may be included into the DMPs for T2DM and CHD. TRIAL REGISTRATION: The study was registered in the German Clinical Trials Registry (Deutsches Register Klinischer Studien (DRKS)) in early 2019 under the number 00020592. This registry has been affiliated with the WHO Clinical Trials Network ( https://www.drks.de/drks_web/setLocale_EN.do ) since 2008. It is based on the WHO template, but contains some additional categories for which information has to be given ( https://www.drks.de/drks_web/navigate.do?navigationId=entryfields&messageDE=Beschreibung%20der%20Eingabefelder&messageEN=Description%20of%20entry%20fields ). A release and subsequent number assignment only take place when information for all categories has been given.

Autologous Lipotransfer - Daily Therapeutic Practice in Breast Cancer: An Intergroup Analysis Encompassing NOGGO, WSG, GBG, AWO Gyn and DGPRÄC.

BACKGROUND: Autologous fat transfer in breast reconstruction has become increasingly important in breast reconstructive surgery. Although the indication to obtain fat, the various operative procedures, and the risks for the patient have been addressed in a large number of studies, detailed information on the everyday use of autologous lipotransfer in breast units in Germany is still lacking. METHODS: The objective of the study was to obtain primary data on the use of autologous lipotransfer to treat breast cancer patients in Germany and to determine measures for quality assurance in the daily practice. An online questionnaire concerning breast cancer and lipofilling was sent to specialists in gynecology and plastic surgery. RESULTS: Two-thirds of the specialists who responded to the questionnaire use autologous lipotransfer for breast reconstruction and did not report an increase of local recurrence following lipotransfer. There were only small differences between gynecologists and plastic surgeons regarding the procedure and indication for lipotransfer. The method is highly accepted by patients and physicians, and both gynecologists and plastic surgeons rated the improvement achieved through lipofilling as 'high'. CONCLUSIONS: The lack of randomized controlled data, especially in high-risk patients, demonstrates the necessity for a registry study on this topic. Our survey describes, in detail, the indications for lipofilling as well as its appropriate application in breast cancer patients in Germany and may thereby reduce the present therapeutic uncertainties.

Jumping Breast Phenomenon Following Subcutaneous Mastectomy: First Description and Grading of a Well-Known Breast Deformity.

INTRODUCTION: One of the goals of breast cancer surgery is to preserve the breast. However, where this is not possible, various breast reconstructive procedures are available. The most common procedure is the immediate insertion of a subpectoral implant after removing the breast tissue. A significant challenge involving subpectoral implants is the deformation of the breast upon contraction of the pectoral muscle causing elevation of the breast and development of wrinkles or ripples in the caudal and cranial quadrants (jumping breast), especially in slim patients with a thin subcutaneous fat layer. METHODS: While the jumping breast phenomenon after augmentation is well-known in cosmetic breast surgery, it has never been systematically described. In oncologic breast surgery, this deformity, which at times can be quite severe, has been ignored thus far. RESULTS AND CONCLUSION: In this paper, we present an initial distinction of grades for the so-called jumping breast, show examples for the different grades of severity of breast deformity in response to tensing of the pectoral muscle, and further describe different primary and secondary procedures for the prevention of the jumping breast phenomenon. By means of a 2-stage procedure, we can prevent this complication and reduce the risk of breast deformity after implant-based breast reconstruction.
