Association of Sleep Apnea and cardiovascular mortality in CAD patients

Abstract Background A growing body of epidemiological and clinical research has uncovered a significant relationship between sleep apnea and the exacerbation of cardiovascular outcomes, notably myocardial infarction, stroke, and cardiac death. Individuals diagnosed with coronary artery disease (CAD) alongside sleep apnea are identified to have a heightened likelihood of experiencing recurrent cardiovascular events. Despite these associations, the link between sleep apnea and an elevated risk of mortality among CAD patients remains insufficiently explored. Purpose Our study aims to shed light on the impact of sleep apnea on mortality rates within this patient population, potentially guiding future therapeutic strategies. Methods Our cohort study leveraged data from the TriNetX multinational electronic health record network, focusing on patients aged 18 and above diagnosed with coronary artery disease. Participants were stratified into two groups based on the diagnosis of sleep apnea. To ensure a fair comparison, we adjusted for prevalent risk factors such as hypertension, diabetes, dyslipidemia, obesity, and chronic kidney disease, which are commonly observed in CAD patients. Results The study encompassed 1,799,812 patients, equally divided into two groups of 899,906 individuals each, one with sleep apnea and the other without. Over a 5-year observation period, the primary endpoint, defined as event-free survival, was significantly lower in the sleep apnea group (74.385%) compared to the non-sleep apnea group (76.606%), with a Log Rank confidence interval of 1.128 to 1.148 and a p-value of <0.0001. This outcome highlights a association between sleep apnea and increased mortality rates in CAD patients. Conclusion The findings from our large cohort study underscore the critical impact of sleep apnea on mortality among patients with coronary artery disease. The diagnosis of sleep apnea in CAD patients within the TriNetX cohort was significantly associated with a higher mortality rate over a span of five years. These insights emphasize the need for integrated care strategies that not only address the primary cardiovascular conditions but also prioritize the diagnosis and management of sleep apnea to potentially improve survival outcomes in this vulnerable patient group. Our study calls for heightened clinical awareness and further research to elucidate the mechanisms behind this association and to explore the benefits of targeted sleep apnea interventions in reducing mortality rates among CAD patients.5-year Kaplan-Meier curves for mortality

Implementation of sodium-glucose co-transporter 2 inhibitors in patients with heart failure through a new digital strategy (EMAIL-HF): a randomised clinical trial study design

Abstract Introduction Delayed implementation of new medical discoveries remains a global healthcare challenge and is mainly due to the complexity of cross-institutional patient care. Sodium-glucose co-transporter-2 (SGLT-2) inhibitors is the latest medical discovery in heart failure (HF) and have recently been added to clinical guidelines as they have proven to reduce the risk of adverse cardiovascular outcomes in patients with HF across the ejection fraction spectrum. Whether a new digital strategy can optimise and accelerate the implementation of SGLT2 inhibitors in patients living with HF is of great importance for public health. Purpose To evaluate whether a new and streamlined digital strategy can optimise and accelerate the implementation of SGLT2 inhibitors in patients with HF. Design and methods: The trial is a multicentre, parallel group, register-based randomised clinical study, evaluating the effect and potential of a new digital strategy to implement new guideline therapies to patients living with a chronic disease, specifically SGLT2 inhibitors to patients with HF (figure 1). The setup employs data from nationwide health registers and official digital letters to inform patients about the new therapy option and invite them to have their eligibility evaluated by a HF specialist and start therapy. A total of ~10,000 patients with HF across the ejection fraction spectrum (with and without diabetes), who have not yet been started on SGLT2 inhibitors, are identified through Danish nationwide health registers, and randomised 1:1 to receive the digital letter (figure 2). The primary outcome is the proportion of patients redeeming a prescription of a SGLT2 inhibitor within six months. Secondary outcome is a composite HF endpoint consisting of all-cause death or HF hospitalisation. Other outcome measures are renal failure, stroke and myocardial infarction, safety outcomes, adherence to therapy and proportion of vulnerable patient groups initiating therapy including immigrants, elderly, frail patients, patients with lower socioeconomic level and lower educational level. A total of 4689 patients have been randomised (February 2024) and data will be presented in 2025. Conclusions The trial will determine the efficacy and safety of a new and streamlined digital strategy to implement SGLT2 inhibitors to patients with chronic HF. The setup has the potential to be used in a broad spectrum of patients living with chronic diseases and is expected to be highly cost-effective.Figure 1.Study hypothesisFigure 2.Study design

Virtual clinics in oral surgery: an equitable service for all?

Introduction Teledentistry has become more prevalent in the provision of oral healthcare since the COVID-19 pandemic. Virtual consultation clinics were introduced at Birmingham Dental Hospital as an adjunct to face-to-face (F2F) consultation clinics. This service evaluation compares virtual and F2F consultation clinics in oral surgery, with particular focus on 'did not attend' (DNA) rates.Methodology Data were collected retrospectively from all clinics conducted within the oral surgery service in April 2021. Information collected included attendance, patient demographics and complications impeding the consultation, including technical difficulties. Patients' postcodes were used to generate deprivation deciles. All data were handled sensitively in line with the Caldicott principles.Results Binomial regression analysis showed that DNA rates were more likely to occur in virtual consultation clinics compared to F2F clinics (p <0.00). DNAs were less likely to occur at review appointments (p <0.00). Lower deprivation decile ratings were associated with higher rates of DNAs, independent of clinic type (eg review or new patient) or method of consultation (virtual versus F2F) (p <0.01).Conclusion While virtual clinics are advantageous for some patient demographics and have shown promising results in other studies, it is important that the delivery of these virtual services does not continue to marginalise vulnerable patient groups and enhance pre-existing oral health inequalities.

The impact of viral respiratory infection on surgical outcome of cavopulmonary shunt.

Undetected respiratory infections may adversely affect the intrapulmonary resistance after Stage 2 or Stage 3 Fontan palliation. A few studies describe a higher risk for viral pneumonia during respiratory virus season, but none of them have focused on the effect of symptomatic viral pneumonia on in-hospital clinical course after bidirectional Glenn shunt. We analysed 77 patients who underwent bidirectional Glenn shunt surgery. Six patients were detected with pneumonia and proof of viral ribonucleic acid in tracheal mucus in the very early postoperative time. We compared them retrospectively to the remaining 71 patients regarding preoperative inflammatory signs, mortality, paediatric ICU length of stay, and ventilation time. The infection rate was not seasonal dependent. Ventilation time was significantly elongated in the pneumonia group (558 h ± 634 vs. 8.7 h ± 1.9; p < 0.0001) and so was the paediatric ICU length of stay (29 days ± 26 vs. 3 days±1; p = 0.007). Significantly more patients in the pneumonia group required extracorporeal cardiac life support postoperatively. The mortality was significantly increased in patients with pneumonia. Even subclinical viral pneumonia may cause ventilation-to-perfusion mismatch by raising intrapulmonary resistance. Recorded parameters of postoperative paediatric ICU therapy showed a significant impact of a viral pneumonia on patients after bidirectional Glenn shunt. The respiratory syncytial virus vaccination does not protect these patients from infection with other respiratory viruses. The focus should be put on preoperative diagnosis of pulmonary infections in the vulnerable group of patients with univentricular hearts.

A scoping review on cancer and body image research

The purpose of this research is to explore previous studies that investigated the body image of cancer patients and survivors by identifying the variables that have been examined and the gaps in the current research through a scoping review. The researchers conducted extensive and methodical searches in several databases using relevant keywords. After analyzing the full text of 89 papers, 45 studies were included in this review, published between 1995 and 2024. Most of the studies were conducted solely with female participants, and breast cancer was the most commonly researched cancer type. The researchers identified variables that affect the body image perspectives of this population, with the surgery method being the most frequently tested variable, followed by education level, age, cancer state, and mental health. This scoping review highlights the need to pay particular attention to a vulnerable group of under-educated female cancer patients who must undergo invasive cancer treatment.

Unraveling the impact of abdominal arterial calcifications on kidney transplant waitlist mortality through ensemble machine learning

The scarcity of organ donors relative to the number of patients with End Stage Kidney Disease (ESKD) has led to prolonged waiting times for kidney transplants, contributing to elevated cardiovascular mortality risk. Transplant professionals are tasked with the complex allocation of limited organs to a vulnerable patient group facing heightened morbidity and mortality risk. The need for continuous re-evaluation of waitlisted patients is evident due to the significant number who perish while awaiting transplantation. Among individuals with ESKD, vascular calcification, particularly Abdominal Arterial Calcifications (AAC), holds predictive value for cardiovascular events and mortality. However, a standardized method to quantify AAC’s prognostic potential remains lacking, especially for kidney transplant evaluations. This study presents an ensemble machine learning (ML) approach to study the relationship between AAC score and mortality in patients on the waitlist and triage patients needing transplantation. Using the AAC score, the proposed ML model can predict kidney transplant waitlist morality with an accuracy of 78% while its accuracy is 68% without using this score. This study leverages explainable ML to explore the relationship between predictors and mortality in waitlisted patients, aiming to improve patient triage accuracy.

Obsessive-compulsive symptoms relating to psychosocial functioning for people with schizophrenia, schizoaffective disorder, or bipolar disorder.

To assess the psychosocial functioning concerning obsessive-compulsive symptoms (OCS) and/or obsessive-compulsive disorder (OCD) comorbidity in people with schizophrenia, schizoaffective disorder, or bipolar disorder diagnosed in a large case register database in Southeast London. Data were retrieved from the South London and Maudsley NHS Foundation Trust Biomedical Research Centre (SLaM BRC) register using Clinical Record Interactive Search (CRIS) system, a platform allowing research on full but de-identified electronic health records for secondary and tertiary mental healthcare services. Information of schizophrenia, schizoaffective disorder, bipolar disorder diagnosis and OCS/OCD status was ascertained from structural or free-text fields through natural language processing (NLP) algorithms based on artificial intelligence techniques during the observation window of January 2007 to December 2016. Associations between comorbid OCS/OCD and recorded Health of the Nation Outcome Scales (HoNOS) for problems with activities of daily living (ADLs), living conditions, occupational and recreational activities, and relationships were estimated by logistic regression with socio-demographic confounders controlled. Of 15,412 subjects diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder, 2,358 (15.3%) experienced OCS without OCD, and 2,586 (16.8%) had OCD recorded. The presence of OCS/OCD was associated with more problems with relationships (adj.OR = 1.34, 95% CI: 1.25-1.44), ADLs (adj.OR = 1.31, 95%CI: 1.22-1.41), and living conditions (adj.OR = 1.31, 95% CI: 1.22-1.41). Sensitivity analysis revealed similar outcomes. Comorbid OCS/OCD was associated with poorer psychosocial functioning in people with schizophrenia, schizoaffective disorder, or bipolar disorder. This finding highlights the importance of identification and treatment of comorbid OCS among this vulnerable patient group.

12406 Epidemiology Of Multiple Endocrine Neoplasia Type 1 In South Korea: A Nationwide Cohort Study

Abstract Disclosure: K. Kim: None. Y. Hwang: None. M. Yu: None. S. Moon: None. N. Hong: None. Y. Rhee: None. Multiple Endocrine Neoplasia Type 1 (MEN1) is one of the rarest endocrine disorders, with a scarcity of comprehensive epidemiological data globally. This deficiency in data is even more pronounced in Asian populations, where MEN1 remains an under-researched area. Therefore, our aim is to identity the prevalence, demographic characteristics, and patterns of comorbidities associated with MEN1.This nationwide cohort study assessed likely MEN1 cases from the Korean National Health Insurance Service database (2003-2020), selected via two operational definitions: one requiring an ICD-10 code for MEN1 (D44.8) and the other mandating at least two related procedures for MEN1-associated conditions (Primary Hyperparathyroidism, Pituitary Adenomas, and Duodenopancreatic Neuroendocrine Tumors). Cases were 1:10 matched by age, sex, and index year with controls who did not have any MEN-1 associated tumors. Our study evaluated 412 patients with likely MEN1 (mean age 43.6 ± 15.8 years; 35.4% male) against an age-sex matched control group of 4,120. Baseline characteristics showed a higher prevalence of comorbidities in MEN1 patients, including diabetes mellitus (22.6% vs 4.8%), hypertension (38.1% vs 16.4%), and dyslipidemia (20.6% vs 11.2%), all with p&amp;lt;0.001. Cancer prevalence was markedly elevated in MEN1 patients across most types, compared to controls. Adrenal involvements were observed in 34.7% of MEN1 patients, with adrenal adenoma being the most common (31.6%). Parathyroid, pituitary, and duodenopancreatic involvements were identified in 58.6%, 22.3%, and 19.9% of MEN1 patients, respectively. Mortality analysis revealed MEN1 patients had a higher mortality rate (16.0 per 1000 person-years) and a younger mean age at death (60.1 years) compared to controls (68.0 years), with an adjusted mortality hazard ratio of 3.1. Additionally, mortality risk varied with organ involvement; parathyroid involvement showed an adjusted HR of 2.7, pituitary involvement 4.7, and duodenopancreas involvement 4.0. The risk increased significantly with multi-organ involvement, where patients affected in more than two organs had HRs from 2.8 to 7.3. Our findings indicate that MEN1 significantly impacts patient morbidity and mortality, necessitating improved surveillance and tailored management to enhance early detection and optimize care for this vulnerable patient group. These insights underscore the pressing need for further research into MEN1 and other rare diseases to advance patient care and outcomes. Presentation: 6/2/2024

Comprehensive secondary analysis of thrombotic events in pediatric patients receiving extracorporeal membrane oxygenation: A prospective cohort study.

This study aims to describe laboratory and clinical factors associated with thrombotic events during prolonged pediatric extracorporeal membrane oxygenation. A secondary analysis of a multi-center prospective study performed between 2012 and 2014. Patients under the age of 19years that received extracorporeal membrane oxygenation for at least 4days of therapy were included (n = 385). Univariable analysis and binomial regression were performed to evaluate predictive factors of single and multiple thrombotic events. A posteriori scoring tool was created to categorize thrombotic event severity. Over 39% of children receiving prolonged ECMO experienced a thrombotic event (TE). Binomial regression demonstrated an association between higher transfused platelet volume (mL/kg) (OR 1.04, CI: 95% 1.01-1.06, p = 0.003), Anti-Xa (OR 5.38, CI: 95% 1.22-23.8, p = 0.026) and aPTT (OR 1.01, CI: 95% 1.00-1.02, p = 0.032) the day prior to TE. Patients experiencing multiple TEs were associated with higher platelet transfusion volume (mL/kg) (OR 1.08, CI: 95% 1.05-1.12, p =< 0.001), antithrombin III (OR 1.03, CI: 95% 1.01-1.04, p = 0.001) and aPTT (OR 1.02, CI: 95% 1.01-1.03, p = 0.009). Patients experiencing multiple thrombotic events had a higher risk of 28-day mortality based on a cumulative clot severity score >4 (OR 2.37 (CI: 95% 1.32-4.24). Current lab tests show limited sensitivity to predict these events the day prior in a vulnerable patient group, leading to potential ECMO circuit failures. Patients with multiple thrombotic events during ECMO therapy face increased mortality risks, highlighting the need for dynamic reporting tools like clot severity scores and detailed documentation of interventions to enhance understanding and improve outcomes.

Sarcopenia influences clinical outcome in hospitalized patients with peripheral artery disease aged 75 years and older

ObjectivesSarcopenia represents a relevant comorbidity in patients with peripheral artery disease (PAD). However, only few studies exist assessing the clinical burden of sarcopenia in PAD. MethodsAll hospitalizations of patients aged ≥75 years who were admitted due to PAD within 2005-2020 in Germany were included in the study and stratified for sarcopenia. Temporal trends and the impact of sarcopenia on treatment procedures as well as adverse in-hospital events were investigated. ResultsOverall, 1,166,848 hospitalization-cases of patients admitted due to PAD (median age 81.0 [78.0-85.0] years; 49.5% female sex) were included, of which 2109 (0.2%) were coded with sarcopenia. Prevalence of sarcopenia in these patients increased during the observational period from 0.05% in 2005 to 0.34% in 2020 (β 2.61 [95%CI 2.42 to 2.80], P<0.001). Sarcopenic PAD patients were more often female (52.1% vs. 49.5%, P=0.015), obese (6.6% vs. 5.5%, P=0.021) and revealed higher prevalences of comorbidities (Charlson comorbidity index, 7.00 [6.00-9.00] vs. 6.00 [5.00-7.00], P<0.001). Sarcopenia was associated with reduced usage of reperfusion treatments (endovascular intervention: OR 0.409 [95%CI 0.358-0.466], P<0.001; surgical revascularization: OR 0.705 [95%CI 0.617-0.805],P<0.001), but higher conduction of amputation (OR 1.365 [95%CI 1.231-1.514], P<0.001) and higher rates of major adverse cardiovascular and cerebrovascular events (OR 1.313 [95%CI 1.141-1.512], P<0.001) and in-hospital death (OR 1.229 [95%CI 1.052-1.436], P=0.009). ConclusionsSarcopenia is an under-recognized condition in PAD patients of high clinical relevance causing a crucial disease burden. Awareness of the ailment needs to be increased in daily clinical practice to identify sarcopenia and improve clinical outcome of this vulnerable patient group.

Kidney Replacement Therapies in Advanced Heart Failure - Timing, Modalities, and Clinical Considerations.

Acute kidney dysfunction is commonly encountered in advanced heart failure and carries significant prognostic implications, often leading to poorer outcomes and increased mortality. It can alter the course of decision making for left ventricular assist device (LVAD) and cardiac transplantation candidacy. Kidney replacement therapies (KRT) offer a critical intervention in this context but require careful consideration of timing, various types of KRT modalities, individual patient preferences and circumstances. This review discusses the intricacies of KRT in advanced heart failure, examining how to optimize timing and choose among the various KRT modalities. It also provides a detailed discussion on the unique clinical scenarios that clinicians may face when treating this vulnerable patient group.

Adrenal Insufficiency in Patients with Beta Thalassemia: A Meta-Analysis

Background and Objectives: Adrenal insufficiency (AI) can be a significant concern in patients with transfusion-dependent homozygous beta thalassemia (bThal) due to the chronic disease burden and frequent blood transfusions that these patients require. The prevalence of AI in this population remains unclear, with studies often lacking control groups for comparison. This meta-analysis aimed to estimate the proportion of patients with transfusion-dependent bThal who exhibit evidence of AI. Materials and Methods: A systematic review following PRISMA guidelines identified 19 studies for analysis. Results: Despite the variability in the diagnostic methods used to ascertain AI, the meta-analysis revealed that approximately one-third of patients had evidence of AI, with the prevalence rising to 50% in studies focused on adults with bThal. Conclusions: These findings suggest an increased risk of AI in patients with bThal compared to the general population. Clinicians should consider tailored management strategies, including glucocorticoid coverage during surgical procedures, to mitigate the risk of adrenal crises in this vulnerable patient group. Further research is needed to optimize adrenal surveillance and management in patients with bThal.

Alcohol consumption in cancer patients receiving psycho-oncologic care analysis of socio-demographic, health-related and cancer-related factors.

The carcinogenic effects of alcoholic beverages and the negative impact of alcohol consumption on cancer progression and treatment outcomes are well established in oncology research. Many cancer patients experience significant psychological distress, often manifesting as elevated levels of depression and anxiety. In the general population, alcohol consumption is commonly used as a coping mechanism for such distress. For cancer patients facing substantial psychological challenges, psycho-oncology care is available to help manage their symptoms and the overall impact of their condition. However, there is limited understanding of the alcohol consumption patterns in this particularly vulnerable group of patients, as well as the disease-related factors that may influence their drinking behavior. This study aims to examine the prevalence of potentially risky alcohol consumption in cancer patients receiving psycho-oncology care and to identify sociodemographic, health-related, and psychosocial factors associated with alcohol consumption after cancer diagnosis. By understanding drinking patterns and the factors associated with them, we aim to promote healthier behaviors and enhance treatment outcomes for cancer patients receiving psycho-oncology care. A consecutive sample of 1.225 patients from the psycho-oncology outpatient clinic of the University Medical Center Hamburg Eppendorf (UKE) was analyzed with regard to their alcohol consumption behavior using the Alcohol Use Disorders Identification Test-Consumption Items (AUDIT-C). Self-report questionnaires were employed to assess sociodemographic, health-related, and cancer-specific information. For statistical analysis, multiple linear regression was utilized. In the sample of cancer patients receiving psycho-oncology support one in six of both female and male patients showed risky alcohol drinking behavior (e.g. AUDIT-C above three for women and four for men). In the analysis (R-Square: 0.056) male gender (regression coefficient B 0.686, 95% CI: 0.453-0.919) and patientsreporting a higher physical health-related quality of life (SF8-PCS) (B 0.021, 95% CI: 0.011-0.032) were associated with higher levels of alcohol consumption, whereas having children (B -0.481, 95%CI: -0.700- -0.262) was associated with lower alcohol consumption. With regard to cancer type, a single-factor analysis of variance with gender as the centered covariate showed that patients with gastrointestinal cancer had had lower average consumption levels compared to the groups of patients with breast cancer, melanoma, genitourinary cancer, and lymphoma. Also, patients with sarcoma had lower average consumption levels than patients with lymphoma. The results allow to identify patient characteristics and cancer types associated with higher or lower alcohol consumption levels and higher likelihood of risky consumption behavior in this sample of cancer patients receiving psycho-oncological support. Cancer patients are particularly susceptible to the hazardous effects of alcohol consumption. The results of this study help to identify cancer patients at risk of worsening prognosis due to alcohol consumption and to develop intervention programs to minimize alcohol consumption in this group.

Efficacy of late-onset antiviral treatment in immunocompromised hosts with persistent SARS-CoV-2 infection.

Four years after the onset of the global coronavirus disease 2019 (COVID-19) pandemic, the immunocompromised are at greatest risk of developing life-threatening severe disease. However, specific treatment plans for this most vulnerable patient group have not yet been developed. Employing a CD4+ and CD8+ T cell-depleted immunocompromised mouse model of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, we explored therapeutic options of persistent infections with standard-of-care paxlovid, molnupiravir, and the experimental therapeutic 4'-fluorouridine (4'-FlU). Late-onset treatment initiated 14 days after infection was efficacious, but only 4'-FlU was rapidly sterilizing. No treatment-experienced viral variants with reduced susceptibility to the drugs emerged, albeit virus replication rebounded in animals of the paxlovid group after treatment end. This study supports the use of direct-acting antivirals (DAAs) for late-onset management of persistent SARS-CoV-2 infection in immunocompromised hosts. However, treatment courses likely require to be extended for maximal therapeutic benefit, calling for appropriately powered clinical trials to meet the specific needs of this patient group.

Paediatric formulations-part of the repurposing concept?

The lack of available appropriate paediatric formulations is a significant challenge for optimal treatment in children. The resulting manipulation of adult medicines implies risk of medication errors, inaccurate dosing, and unacceptable dosage forms resulting in non-compliance. This represents significant unmet needs for a large and vulnerable patient group. Currently, the repurposing discussions seems only to a limited degree to cover the aspects of paediatric off-label use of adult medicines, including reformulation strategies to cover unmet needs for suitable formulations in the youngest age groups. Similarly, limited focus seems to be put on incentives in this specific area of repurposing. This paper will discuss the role of reformulation for paediatric needs as part of the repurposing concept, and potential factors contributing to barriers to incentivise the development of new formulations for children.

Vaccination Rates in Patients with Chronic Inflammatory Skin Diseases and Immunomodulatory Systemic Therapies-Vaccinations against SARS-CoV-2, Influenza Virus or Varicella Zoster Virus.

The national guidelines and the Standing Committee on Vaccination (STIKO) of the Robert Koch Institute (RKI) in Germany support preventive vaccinations for patients under immunomodulatory treatments. Retrospective analysis of data from patients with chronic inflammatory skin diseases from December 2021 to December 2022 with a focus on preventive vaccinations against influenza virus, varicella zoster virus, or SARS-CoV-2. Patients with chronic inflammatory skin diseases were referred to our university outpatient's clinic for recommendations of systemic therapy. Vaccinations against influenza virus, varicella zoster virus, or SARS-CoV-2 were documented in 7365 analyzed patient files. A total of 79.7% were completely vaccinated against SARS-CoV-2, 49.7% patients were vaccinated against the influenza virus, and only 9.2% were completely vaccinated against varicella zoster virus. In our patients who came for counselling before or during systemic treatment, vaccination rates against SARS-CoV-2, varicella zoster virus, or influenza virus were low. Patients age 60 and above had higher rates than the average German population of the same age, but still no satisfying protection. We suggest informing patients about preventive vaccination before and during systemic immunomodulatory treatments and emphasize the need for active communication in this vulnerable patient group.

Current Advances and Challenges in the Management of Cutaneous Squamous Cell Carcinoma in Immunosuppressed Patients.

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin malignancy and poses a significant risk to immunosuppressed patients, such as solid organ transplant recipients and those with hematopoietic malignancies, who are up to 100 times more likely to develop cSCC compared with the general population. This review summarizes the current state of treatment for cSCC in immunosuppressed patients, focusing on prevention, prophylaxis, surgical and non-surgical treatments, and emerging therapies. Preventative measures, including high-SPF sunscreen and prophylactic retinoids, are crucial for reducing cSCC incidence in these patients. Adjusting immunosuppressive regimens, particularly favoring mTOR inhibitors over calcineurin inhibitors, has been shown to lower cSCC risk. Surgical excision and Mohs micrographic surgery remain the primary treatments, with adjuvant radiation therapy recommended for high-risk cases. Traditional chemotherapy and targeted therapies like EGFR inhibitors have been utilized, though their efficacy varies. Immunotherapy, particularly with agents like cemiplimab and pembrolizumab, has shown promise, but its use in immunosuppressed patients requires further investigation due to potential risks of organ rejection and exacerbation of underlying conditions. Treatment of cSCC in immunosuppressed patients is multifaceted, involving preventive strategies, tailored surgical approaches, and cautious use of systemic therapies. While immunotherapy has emerged as a promising option, its application in immunosuppressed populations necessitates further research to optimize safety and efficacy. Future studies should focus on the integration of personalized medicine and combination therapies to improve outcomes for this vulnerable patient group.

Pediatric Chronic Intestinal Failure: Something Moving?

Pediatric chronic intestinal failure (PIF) is a rare and heterogeneous condition characterized by the inability of the patient's intestine to adequately absorb the required fluids and/or nutrients for growth and homeostasis. As a result, patients will become dependent on home parenteral nutrition (HPN). A MEDLINE search was performed in May 2024 with keywords "intestinal failure", "parenteral nutrition" and "pediatric". Different underlying conditions which may result in PIF include short bowel syndrome, intestinal neuromuscular motility disorders and congenital enteropathies. Most common complications associated with HPN are catheter-related bloodstream infections, catheter-related thrombosis, intestinal failure-associated liver disease, small intestinal bacterial overgrowth, metabolic bone disease and renal impairment. Treatment for children with PIF has markedly improved with a great reduction in morbidity and mortality. Centralization of care in specialist centers and international collaboration between centers is paramount to further improve care for this vulnerable patient group. A recently promising medical therapy has become available for children with short bowel syndrome which includes glucagon-like peptide 2, a naturally occurring hormone which is known to delay gastric emptying and induce epithelial proliferation. Despite advances in curative and supportive treatment, further research is necessary to improve nutritional, pharmacological and surgical care and prevention of complications associated with parenteral nutrition use.

Corona vaccination under immunosuppression

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to play a major role as a severe and potentially fatal airway infection, especially in vulnerable patient groups. In view of the thin data situation on the influence of treatment and response to vaccination, at the beginning of the corona pandemic it was a major challenge to predict the tolerability and effectiveness in patients with inflammatory rheumatic diseases under immunomodulation or immunosuppression. In the meantime, numerous studies have addressed the questions of response and tolerability, at least for the COVID-19 vaccination. Even in the first months of the vaccination campaign, a small study on a single center cohort could show that apart from patients with B‑cell depletion, all included patients showed a seroconversion after the first two vaccinations. This resulted in neither an increased occurrence of exacerbations of the underlying disease nor new autoimmune phenomena. Various studies have since then confirmed these data.

Socioeconomic status as a risk factor for SARS-CoV-2 infection in pregnant women.

Due to the association between COVID-19 and adverse pregnancy outcomes, pregnant women are considered to be a vulnerable patient group. Studies have shown that low socioeconomic status (SES) is a risk factor for SARS-CoV-2 infection. COVID-19 and low SES are likely to have a synergistic adverse effect. This study aimed to evaluate the socioeconomic background, indicated by self-reported SES, educational level, and financial situation, in pregnant women who were positive for SARS-CoV-2. A case-control study was conducted, including all pregnant women with positive SARS-CoV-2 PCR tests at Kepler University Hospital Linz between May 2020 and August 2021 (n=150) and a control group matched 1:1 relative to gestational age at birth (n=150). Data were collected using written questionnaires and medical records from the hospital information system. Lower self-reported socioeconomic status (p=0.029) and lower education level (p=0.003) were detected in the COVID group. Mothers in the COVID group were significantly younger (p=0.024). However, after adjustment for educational attainment, younger age was not confirmed as a risk factor for SARS-CoV-2 infection during pregnancy (p=0.326). The social gradient was not explained by the assumed mediators and confounders. These findings confirm an association between lower socioeconomic status and the risk of SARS-CoV-2 infection during pregnancy. Since both socioeconomic factors and COVID-19 impose negative effects on pregnancy outcomes, health inequalities should be taken into consideration when implementing SARS-CoV-2 prevention measures and when providing health care for pregnant women from disadvantaged communities.
