Connective tissue disorders predispose patients to earlier aortic dissections and aneurysms. However, there is limited large cohort data given its low incidence.

The National Inpatient Samplewas searched for all adults with Marfans (MFS) and Ehlers Danlos (EDS) disease between 2010 and 2017. ICDcodes were used to select those with a type A aortic dissection or aneurysm.

There was a total of 19,567 cases, giving the estimated incidence of MFS and EDS of 18 and 22.4 per 100k people, respectively. After inclusion criteria, there were 2553 MF and 180 EDS patients. There was no statistical difference in mortality between the MFS and EDS cohorts (4.6% vs. 2.8%, p = .26). EDS patients were more likely to undergo a TEVAR procedure (2.8% vs. 1.0%, p = .03). Tubastatin A MF patients were more likely to have a complication of acute kidney injury (p = .02). EDS patients were more likely older (50 vs. 42, p < .001) and female (47% vs. 33%, p < .001). MFS patients were more likely to have a type A aortic dissection (44% vs. 31%, p < .001). The majority (89%) of patients were treated at urban teaching hospitals. On univariable logistic regression, aortic dissection was a predictor for mortality (odds ratio7.31, p < .001). The type of connective tissue disease was not a significant predictor.

National level estimates show low mortality for patients with MF or ED presenting to the hospital with aortic dissection or aneurysm. The differences in age and gender can guide surveillance for these patient populations, leading to more elective admissions and reduced hospital mortality.

Toward this end, we developed a novel approach that combines occurrence records, spatial-environmental data, and genetic information to model habitat, connectivity, and patterns of genetic structure and link spatial attributes to underlying ecological mechanisms. Using the threatened northern quoll (Dasyurus hallucatus) as a case study, we applied this approach to address the need for conservation decision-making tools that promote resilient metapopulations of this threatened species in the Pilbara, Western Australia, a multiuse landscape that is a hotspot for biodiversity and mining. Habitat and connectivity were predicted by different landscape characteristics. Whereas habitat suitability was overwhelmingly driven by terrain ruggedness, dispersal was facilitated by proximity to watercourses. Although there is limited evidence for major physical barriers in the Pilbara, areas with high silt and clay content (i.e., alluvial and hardpan plains) showed high resistance to dispersal. Climate subtlety shaped distributions and patterns of genetic turnover, suggesting the potential for local adaptation. By understanding these spatial-environmental associations and linking them to life-history and metapopulation dynamics, we highlight opportunities to provide targeted species management. To support this, we have created habitat, connectivity, and genetic uniqueness maps for conservation decision-making in the region. These tools have the potential to provide a more holistic approach to conservation in multiuse landscapes globally.
Management of sternal wound infections (SWIs) in pediatric patients following congenital heart surgery can be extremely difficult. Patients with congenital cardiac conditions are at risk for complications such as sternal dehiscence, infection, and cardiopulmonary compromise. In this study, we report a single-institution experience with pediatric SWIs.

Fourteen pediatric patients requiring plastic surgery consultation for complex sternal wound closure were included. A retrospective chart review was performed with the following variables of interest demographic data, congenital cardiac condition, respective surgical palliations, development of mediastinitis, causative organism, number of debridements, presence of sternal wires, and choice of flap coverage. Primary endpoints included achieved chest wall closure and overall survival.

Of the 14 patients, 8 (57%) were diagnosed with culture-positive mediastinitis. The sternum remained wired at the time of final flap closure in eight (57%) patients. All patients were reconstructed with pectoralis major flaps, except one (7%) who also received an omental flap and two (14%) who received superior rectus abdominis flaps. One patient (7%) was treated definitively with negative pressure wound therapy, and one (7%) was too unstable for closure. Six patients developed complications, including one (7%) with persistent mediastinitis, two (14%) with hematoma formation, one (7%) with abscess, and one (7%) with skin necrosis requiring subsequent surgical debridement. There were three (21%) mortalities.

The management of SWI in congenital cardiac patients is challenging. The standard tenets for management of SWI in adults are loosely applicable, but additional considerations must be addressed in this unique subset population.

Mycophenolate mofetil (MMF) is the gold-standard immunosuppressive agent in heart transplantation (HT), but dose-dependent toxicities (e.g., neutropenia) are frequent. Gut bacteria β-d-glucuronidases (GUS) modulate MMF bioavailability, and changes in the intestinal flora may influence the pharmacokinetics of MMF. The objective of this study was to evaluate the safety and efficacy of MMF 1.5 g every 12 h (q12) [high-dose, HD] versus 1 g q12 [low-dose, LD] and explore the association between neutropenia and GUS.

We compared the incidence of acute cellular rejection (ACR) and neutropenia during the first 6 months post-HT. The association between neutropenia and GUS was investigated in an exploratory analysis on a subset of patients with prospectively collected stool data. Stool samples were analyzed using 16S rRNA sequencing.

A total of 168 patients (120 MMF-HD, 48 MMF-LD; mean age 55.7 years, 79% male) were studied. Neutropenia occurred in 38.6% of patients at a median of 106 [64-143] days. Freedom from nn could improve clinical outcomes post-HT.
Perimenstrual migraine attacks in women with menstrual migraine is difficult to treat. This post-hoc analysis evaluated the efficacy of lasmiditan, a high affinity and selective 5-HT
receptor agonist, for perimenstrual attacks.

Patients from two randomized, double-blind, placebo-controlled clinical trials (MONONOFU and CENTURION) were instructed to treat an attack with a single dose of study medication within four hours of pain onset. After dosing, the proportion of patients who achieved freedom from migraine-related head pain, most bothersome symptom, and disability was reported at baseline up to 48 hours after dose and pooled data were evaluated.

A total of 303 patients (MONONOFU N = 78; CENTURION N = 225) treated perimenstrual migraine attacks with lasmiditan 50 mg (N = 24), 100 mg (N = 90), 200 mg (N = 110), and placebo (N = 79). More patients achieved migraine-related head pain freedom with lasmiditan 200 mg versus placebo at all time points assessed. At 2 hours, 33.6% of patients in the 200-mg group (p < 0.001), and 16.7% of patients in the 100-mg (p = 0.11) and 50-mg (p = 0.19) groups were pain free, compared with 7.6% in the placebo group.

Lasmiditan treatment of perimenstrual migraine attacks was associated with freedom from migraine-related head pain at two hours, early onset of efficacy, and sustained efficacy.

The prevalence of lymphatic anomalies seems to differ between pathogenic variants. Therefore, this study aims to describe the clinical presentation, prevalence and genotype-phenotype correlations of lymphatic anomalies during life in patients with NS. This retrospective cohort study included patients (n = 115) who were clinically and genetically diagnosed with NS and visited the Noonan expertise Center of the Radboud University Medical Center between January 2015 and March 2021. Data on lymphatic anomalies during lifetime were obtained from medical records. Lymphatic anomalies most often presented as an increased nuchal translucency, chylothorax and/or lymphedema. Prenatal lymphatic anomalies increased the risk of lymphatic anomalies during infancy (OR 4.9, 95% CI 1.7-14.6). The lifetime prevalence of lymphatic anomalies was 37%. Genotype-phenotype correlations showed an especially high prevalence of lymphatic anomalies during infancy and childhood in patients with a pathogenic SOS2 variant (p = 0.03 and p less then  0.01, respectively). This study shows that patients with NS have a high predisposition for developing lymphatic anomalies during life. Especially patients with prenatal lymphatic anomalies have an increased risk of lymphatic anomalies during infancy. Genotype-phenotype correlations were found in pathogenic variants in SOS2.Representing 10%-25% of the primary cardiac neoplasms, primary malignant cardiac tumors (PMCT) have a poor prognosis, yet with rare incidence. Constituting more than 50% of the PMCT, cardiac sarcoma has increased not only in incidence over the past five decades but also in severity. Patients with PMCTs, especially sarcomas, have the worst prognosis when compared with other cardiac or extracardiac tumors. This retrospective study was performed using SEER*stat software, latest version 8.3.9.2(5) by accessing seer 18 registries plus data (excl AK) Nov 2020 Sub (2000-2018) for standard mortality ratio (SMR). A total of 235 patients were identified of whom 49.4% were females. Most of our patients were Stage 4 (n = 81) and distant in location (n = 92). The most common treatment method was tumor-directed surgery (n = 164), chemotherapy (n = 146), and radiotherapy (n = 55). Furthermore, other associated cancers with cardiac sarcoma were rare, with ten cases with lung and bronchus cancer (SMR 37.95, 95% confidence interval [CI] 18.2, 69.8), four with bone and joints (SMR 1726.05, 95% CI 470.2, 4419.3). During a 5-year follow-up, 235 patients died primarily due to cardiac sarcoma (n = 182, 77.4%), other cancers (n = 34, 14.4%), and other noncancerous causes (n = 19, 8%), while the noncancerous causes were attributed mainly to cardiovascular diseases (n = 4, 21%, SMR 4.95, 95% CI 1.35, 12.67), septicemia (n = 2, 10.5%, SMR 41.23, 95% CI 4.99, 148.95).
