Patients with immune mediated inflammatory diseases are insufficiently protected against vaccine-preventable infections
Background Patients with Immune Mediated Inflammatory Diseases (IMIDs) using immunosuppressive therapy are at increased risk of infections, including vaccine-preventable infections. In this study, we aimed to evaluate whether patients with IMIDs on systemic immunosuppressive therapy are vaccinated according to current guidelines. Methods A survey was sent out, between August 2022 and March 2023, to all patients with IMIDs that visited the departments of dermatology, rheumatology and gastroenterology at an academic and regional hospital in Rotterdam, the Netherlands. Patient-reported vaccination status was compared to the Dutch guidelines on vaccinations in patients with chronic inflammatory diseases. Results A total of 1,905/5,987 patients responded to the survey (response rate 32%). After exclusion of patients without systemic immunosuppressive medication, the study population comprised 1,390 patients, median age 56 years (IQR 42-66) and 41% male. Most patients (92%) had been vaccinated according to the Dutch National Immunization Program. Before starting immunosuppressive therapy, 2% of the patients who were still considered at risk according to the Dutch guideline were vaccinated for measles, and 4% for diphtheria/tetanus/polio (DT-IPV). Additionally, 62% of patients received an annual influenza vaccine, 16% received a five-yearly pneumococcal vaccine, and 91% were fully vaccinated against COVID-19. Conclusion Patients with IMIDs on immunosuppressive therapy are not vaccinated in accordance with the guidelines. Implementation strategies to improve the vaccination rates for patients with IMIDs should specifically focus on vaccinating against measles and diphtheria/tetanus/polio, and periodic vaccination against pneumococcal and influenza infections
Data mining to retrieve smoking status from electronic health records in general practice
Aims Optimize and assess the performance of an existing data mining algorithm for smoking status from hospital electronic health records (EHRs) in general practice EHRs. Methods and results We optimized an existing algorithm in a training set containing all clinical notes from 498 individuals (75â712 contact moments) from the Julius General Practitionersâ Network (JGPN). Each moment was classified as either âcurrent smokerâ, âformer smokerâ, ânever smokerâ, or âno informationâ. As a reference, we manually reviewed EHRs. Algorithm performance was assessed in an independent test set (nâ=â494, 78â129 moments) using precision, recall, and F1-score. Test set algorithm performance for âcurrent smokerâ was precision 79.7%, recall 78.3%, and F1-score 0.79. For former smoker, it was precision 73.8%, recall 64.0%, and F1-score 0.69. For never smoker, it was precision 92.0%, recall 74.9%, and F1-score 0.83. On a patient level, performance for ever smoker (current and former smoker combined) was precision 87.9%, recall 94.7%, and F1-score 0.91. For never smoker, it was 98.0, 82.0, and 0.89%, respectively. We found a more narrative writing style in general practice than in hospital EHRs. Conclusion Data mining can successfully retrieve smoking status information from general practice clinical notes with a good performance for classifying ever and never smokers. Differences between general practice and hospital EHRs call for optimization of data mining algorithms when applied beyond a primary development setting
Male Sexual Health and Reproduction in Cutaneous Immune-Mediated Diseases: A Systematic Review
Introduction: Information about the possible effects of cutaneous immune-mediated diseases (cIMDs) on male sexual function and reproduction is scarce. Factors known to impair sexual health and reproduction, such as inflammation, medication use, and hypogonadism, can be present in a significant proportion of male patients with cIMD. Objectives: To systematically review the literature for the influence of paternal cIMD on many aspects of male sexual and reproductive health, such as sexual function, reproductive hormones, fertility, and pregnancy and offspring outcomes. Methods: A systematic literature search was performed. The searches combined keywords regarding male sexual function and fertility, pregnancy outcomes, and offspring's health with a list of cIMDs. Results: The majority of the identified studies included patients with psoriasis (22 of 27), and sexual function was the most common outcome of interest (20 of 27). For patients diagnosed with psoriasis, the prevalence of male sexual dysfunction reported in these studies ranged from 34 to 81%. Hypogonadism in patients with psoriasis was reported in 2 of 3 studies. Sperm analysis abnormalities in patients with psoriasis were reported in 3 of 4 studies. No information about the effect of paternal disease on pregnancy and offspring outcomes was identified. Conclusions: Disease activity in psoriasis might play an important role in the development of sexua
Male Sexual Health and Reproduction in Cutaneous Immune-Mediated Diseases: A Systematic Review
Introduction: Information about the possible effects of cutaneous immune-mediated diseases (cIMDs) on male
sexual function and reproduction is scarce. Factors known to impair sexual health and reproduction, such as
inflammation, medication use, and hypogonadism, can be present in a significant proportion of male patients
with cIMD.
Objectives: To systematically review the literature for the influence of paternal cIMD on many aspects of male
sexual and reproductive health, such as sexual function, reproductive hormones, fertility, and pregnancy and
offspring outcomes.
Methods: A systematic literature search was performed. The searches combined keywords regarding male sexual
function and fertility, pregnancy outcomes, and offspring's health with a list of cIMDs.
Results: The majority of the identified studies included patients with psoriasis (22 of 27), and sexual function was
the most common outcome of interest (20 of 27). For patients diagnosed with psoriasis, the prevalence of male sexual
dysfunction reported in these studies ranged from 34 to 81%. Hypogonadism in patients with psoriasis was reported
in 2 of 3 studies. Sperm analysis abnormalities in patients with psoriasis were reported in 3 of 4 studies. No information
about the effect of paternal disease on pregnancy and offspring outcomes was identified.
Conclusions: Disease activity in psoriasis might play an important role in the development of sexual
dysfunction, hypogonadism, and abnormal sperm quality. For the other cIMD included in this review, there is
insufficient information regarding male sexual and reproductive health to draw firm conclusions. More research is
needed to understand the association between cIMD and impaired male sexual and reproductive health
Multiple perspectives on inference for two simple statistical scenarios
When data analysts operate within different statistical frameworks (e.g., frequentist versus Bayesian, emphasis on estimation versus emphasis on testing), how does this impact the qualitative conclusions that are drawn for real data? To study this question empirically we selected from the literature two simple scenariosâinvolving a comparison of two proportions and a Pearson correlationâand asked four teams of statisticians to provide a concise analysis and a qualitative interpretation of the outcome. The results showed considerable overall agreement; nevertheless, this agreement did not appear to diminish the intensity of the subsequent debate over which statistical framework is more appropriate to address the questions at hand
Intra- and inter-laboratory agreement of the FAM19A4/mir124-2 methylation test: results from an international study
BACKGROUND: HPV-based cervical screening detects women at an increased risk of cervical cancer and precancer. To differentiate among HPV-positive women those with (pre)cancer, triage testing is necessary. The detection of cancer-associated host-cell DNA methylation (FAM19A4 and hsa-mir124-2) in cervical samples has shown valuable as triage test. This multicenter study from 6 collaborating European laboratories and one reference laboratory was set out to determine the intra- and inter-laboratory agreement of FAM19A4/mir124-2 DNA methylation analysis utilizing the QIAsure Methylation Test. METHODS: Agreement analysis for the QIAsure Methylation Test was assessed on high-risk HPV-positive cervical specimens (n = 1680) both at the level of the assay and at the full workflow, including bisulfite conversion. RESULTS: Intra- and inter-laboratory assay agreement were 91.4% (534/584; 95% CI 88.9-93.5; Îș = 0.82) and 92.5% (369/399; 95% CI 90.0-94.7; Îș = 0.83), respectively. The inter-laboratory workflow (bisulfite conversion and assay combined) agreement was 90.0% (627/697; 95% CI 87.5%-92.0%; Îș = 0.76). CONCLUSION: These data show that the QIAsure Methylation Test performs robust and reproducible in different laboratory contexts. These results support the use of the QIAsure Methylation Test for full molecular screening for cervical cancer, including primary HPV testing and triage testing by methylation analysis
Allelic Switching of DLX5, GRB10, and SVOPL during Colorectal Cancer Tumorigenesis
Allele-specific expression (ASE) is found in approximately 20-30% of human genes. During tumorigenesis, ASE changes due to somatic alterations that change the regulatory landscape. In colorectal cancer (CRC), many chromosomes show frequent gains or losses while homozygosity of chromosome 7 is rare. We hypothesized that genes essential to survival show allele-specific expression (ASE) on both alleles of chromosome 7. Using a panel of 21 recently established low-passage CRC cell lines, we performed ASE analysis by hybridizing DNA and cDNA to Infinium HumanExome-12 v1 BeadChips containing cSNPs in 392 chromosome 7 genes. The results of this initial analysis were extended and validated in a set of 89 paired normal mucosa and CRC samples. We found that 14% of genes showed ASE in one or more cell lines and identified allelic switching of the potential cell survival genes DLX5, GRB10, and SVOPL on chromosome 7, whereby the most abundantly expressed allele in the normal tissue is the lowest expressed allele in the tumor and vice versa. We established that this allelic switch does not result from loss of imprinting. The allelic switching of SVOPL may be a result of transcriptional downregulation, while the exact mechanisms resulting in the allelic switching of DLX5 and GRB10 remain to be elucidated. In conclusion, our results show that profound changes take place in allelic transcriptional regulation during the tumorigenesis of CRC
De werkalliantie als onderwerp van gesprek tussen cliënten en professionals
Hoe denken cliĂ«nten en professionals over de kwaliteit van het contact en de onderlinge samenwerking tussen cliĂ«nten en professionals in het (semi)gedwongen kader? En helpt het volgens hen als zij daar samen af en toe systematisch over praten aan de hand van een door ons (Hogeschool Utrecht) ontwikkeld hulpmiddel? En heeft dat hulpmiddel, een vragenlijst, aanpassingen nodig om het beter werkbaar te maken? Deze vragen stonden centraal in het praktijkgerichte onderzoek waarvan we hier verslag doen. De kwaliteit van het contact en de onderlinge samenwerking noemen we âde werkalliantieâ. In een recent empirisch onderzoek is gevonden dat een goede kwaliteit van de werkalliantie in het gedwongen kader voortijdige uitval van cliĂ«nten kan terugdringen (Menger, 2018)
Direct bisulphite conversion of cervical samples for DNA methylation analysis
Sodium bisulphite conversion of DNA to separate methylated from unmethylated cytosines is a standard for methylation analysis. This study evaluated a direct cell conversion protocol on cervical samples as alternative to isolated genomic DNA as input. Clinician-collected cervical samples (n = 120) were subjected to a direct conversion protocol, or genomic DNA was isolated with a fixed amount used for subsequent bisulphite conversion. Converted samples were compared for ACTB control gene and methylation of FAM19A4 and miR124-2 genes using quantitative methylation-specific PCR (QIAsure Methylation Test). Direct conversion resulted in a high success rate, i.e., 119/120 (99.2%) samples reported a valid test result. ÎÎCq values of FAM19A4 and miR124-2 were significantly correlated between both protocols (Spearman Rho 0.708 and 0.763, respectively, all p-values = 0.000). Agreement between both the bisulphite protocols was demonstrated by BlandâAltman plots. A direct cell conversion protocol shows good technical and analytical performance and offers a streamlined workflow for methylation analysis
