During a fatal disease, patients often request updated information on their prognosis. After patients have already survived a certain time, conditional survival captures their future survival probability. We investigated conditional overall and failure-free survival in 473 younger mantle cell lymphoma (MCL) patients from a randomized phase III trial comparing immunochemotherapies R-CHOP and alternating R-CHOP/R-DHAP before autologous transplantation.

Objectives: To investigate tooth-specific, clinical tooth-, and patient-related factors associated with tooth loss (TL) in patients with mild to severe periodontitis treated in a periodontal practice-based research network (Perio-PBRN) over at least 5 years.
Materials And Methods: The Perio-PBRN consists of five German periodontal practices where clinical data were collected regarding patient age, tooth type, bleeding on probing (BOP), pocket probing depth (PPD), furcation involvement (FI), number of attended appointments, and other variables of interest. The data were evaluated regarding factors influencing TL.

Objective: Many diseases are characterised by their seasonal appearance due to circannual changes in immune defence and a lifestyle that changes over the seasons. However, there is a lack of studies regarding the influence of seasonality on periodontitis. Therefore, the aim of this non-interventional, retrospective, observational study was to investigate the influence of seasonality on periodontitis.

Summary: The retarded transient function (RTF) approach serves as a complementary method to ordinary differential equations (ODEs) for modelling dynamics typically observed in cellular signalling processes. We introduce an R package that implements the RTF approach, originally implemented within the MATLAB-based Data2Dynamics modelling framework. This package facilitates the modelling of time and dose dependencies, and it includes the possibility of model reduction to minimize overfitting.

Background: Despite clinical interventional studies on the influence of diet on periodontal inflammatory parameters, there has been no practice-based cross-sectional study from a German population to date that has conducted both a comprehensive dental and periodontal examination and a thorough validated assessment of dietary behavior. Therefore, the aim of this pilot study was to evaluate, in a proof of concept, whether there is a correlation between the overall periodontal inflammatory surface area (PISA), periodontal clinical parameters (pocket probing depths (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), furcation involvement (FI), tooth mobility (TM)), and the dietary behavior of patients with periodontal disease when utilizing a practice-based research network. The primary outcome was the correlation between the periodontal inflammatory surface (PISA) and the dietary assessment data.

This study aims to develop and apply multistate models to estimate, forecast, and manage hospital length of stay during the COVID-19 epidemic without using any external packages. Data from Bellvitge University Hospital in Barcelona, Spain, were analyzed, involving 2285 hospitalized COVID-19 patients with moderate to severe conditions. The implemented multistate model includes transition probabilities and risk rates calculated from transitions between defined states, such as admission, ICU transfer, discharge, and death.

: For patients with percutaneous coronary intervention (PCI) of an unprotected left main coronary artery (uLMCA) stenosis, the optimal duration of dual antiplatelet therapy (DAPT) remains a matter of debate. The purpose of this study was to compare clinical outcomes of 6- versus 12-month DAPT duration in patients with PCI of an uLMCA and stable angina. : In this retrospective analysis, we included consecutive patients of our centre who underwent PCI of uLMCA stenosis for stable angina and who received DAPT with acetylsalicylic acid and clopidogrel for either 6 or 12 months.

The fit of a regression model to new data is often worse due to overfitting. Analysts use variable selection techniques to develop parsimonious regression models, which may introduce bias into regression estimates. Shrinkage methods have been proposed to mitigate overfitting and reduce bias in estimates.

Objectives: There is a paucity of data on the outcome of fixed tooth- and implant-supported porcelain-fused-to-metal (PFM) and ceramic-based (CB) restorations fabricated during undergraduate dental education. Therefore, this retrospective study examined the outcome of fixed restorations placed in patients participating in an undergraduate program.
Methods: Patient records were searched for data on fixed PFM and CB restorations.

Background: Dissecting trends and contributing risk factors for intracranial hemorrhage (ICH) in patients treated for acute pulmonary embolism (PE) may allow for a better patient selection for existing and emerging treatment options.
Methods: The German nationwide inpatient sample was screened for patients admitted due to PE 2005-2020. Hospitalizations were stratified for the occurrence of ICH; risk factors for ICH and temporal trends were investigated.

Laminin β4 was recently identified as a structural component of the dermal-epidermal junction and autoantigen of anti-p200 pemphigoid. In this study, we provided further evidence of the pathogenic effect of anti-laminin β4 IgG and identified potential binding partners of laminin β4. We showed that laminin β4 immune complexes led to activation of normal leukocytes and dose-dependent ROS release.

Background: Pulmonary embolism (PE) is a potentially life-threatening condition. Admission and treatment in the intensive care unit (ICU) is an important element in critically ill PE patients.
Objectives: We aimed to identify risk factors for ICU admission and differences in patient profiles regarding risk factors and comorbidities between PE patients who had to be admitted to an ICU and those who were treated in a normal ward without ICU.

Background: The spread of several severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) variants of concern (VOCs) has repeatedly led to increasing numbers of coronavirus disease 2019 (COVID-19) patients in German intensive care units (ICUs), resulting in capacity shortages and even transfers of COVID-19 intensive care patients between federal states in late 2021. In this respect, there is scarce evidence on the impact of predominant VOCs in German ICUs at the population level.
Methods: A retrospective cohort study was conducted from July 01, 2021, to May 31, 2022, using daily nationwide inpatient billing data from German hospitals on COVID-19 intensive care patients and SARS-CoV-2 sequence data from Germany.

Background: Suboptimal diet quality is a key risk factor for premature death. Assuming relatively stable energy intake among individuals, changes in nutrient intakes occur by exchanging different nutrients. Therefore we aimed to examine the association of isocaloric substitution of dietary (macro)nutrients with all-cause mortality using network meta-analysis (NMA).

Multiple myeloma (MM) is a hematological disease exhibiting aberrant clonal expansion of cancerous plasma cells in the bone marrow. The effects of treatments for MM vary between patients, highlighting the importance of developing prognostic models for informed therapeutic decision-making. Most previous models were constructed at the gene level, ignoring the fact that the dysfunction of the pathway is closely associated with disease development and progression.
