In-Hospital Outcomes in Patients With Non-ST Segment Elevation Myocardial Infarction and Concomitant Neurodevelopmental Disorders in the United States: Insights From the National Inpatient Sample 2011-2020

Patients with neurodevelopmental disorders (NDDs) encounter significant barriers to receiving quality health care, particularly for acute conditions such as non-ST segment elevation myocardial infarction (NSTEMI). This study addresses the critical gap in knowledge regarding in-hospital outcomes and the use of invasive therapies in this demographic. By analyzing data from the National Inpatient Sample database from 2011 to 2020 using the International Classification of Diseases, Ninth Edition (ICD-9) and Tenth Edition (ICD-10) codes, we identified patients with NSTEMI, both with and without NDDs, and compared baseline characteristics, in-hospital outcomes, and the application of invasive treatments. The analysis involved a weighted sample of 7,482,216 NSTEMI hospitalizations, of which 30,168 (0.40%) patients had NDDs. There were significantly higher comorbidity-adjusted odds of in-hospital mortality, cardiac arrest, endotracheal intubation, infectious complications, ventricular arrhythmias, and restraint use among the NDD cohort. Conversely, this group exhibited lower adjusted odds of undergoing left heart catheterization, percutaneous coronary intervention, or coronary artery bypass graft surgery. These findings underscore the disparities faced by patients with NDDs in accessing invasive cardiac interventions, highlighting the need for further research to address these barriers and improve care quality for this vulnerable population.

In-hospital outcomes of septal myectomy vs. alcohol septal ablation for hypertrophic cardiomyopathy with outflow tract obstruction: An update and insights from the national inpatient sample from 2011 to 2019

Septal Myectomy (SM) and Alcohol Septal Ablation (ASA) improve symptoms in patients with Hypertrophic Cardiomyopathy with outflow tract obstruction (oHCM). However, outcomes data in this population is predominantly from specialized centers. The National Inpatient Database was queried from 2011 to 2019 for relevant international classification of diseases (ICD)-9 and -10 diagnostic and procedural codes. We compared baseline characteristics and in-hospital outcomes of patients with oHCM who underwent SM vs ASA. A p-value  < 0.001 was considered statistically significant. We identified 15,119 patients with oHCM who underwent septal reduction therapies, of whom 57.4% underwent SM, and 42.6% underwent ASA. Patients who underwent SM had higher all-cause mortality (OR: 1.8 (1.3-2.5)), post-procedure ischemic stroke (OR: 2.3 (1.7-3.2)), acute kidney injury (OR: 1.4 (1.2-1.7)), vascular complications (OR: 3.6 (2.3-5.3)), ventricular septal defect (OR: 4.4 (3.2-6.1)), cardiogenic shock (OR: 1.7 (1.3-2.3)), sepsis (OR: 3.2 (1.9-5.4)), and left bundle branch block (OR: 3.5 (3-4)), compared to ASA. Patients who underwent ASA had higher post-procedure complete heart block (OR: 1.3 (1.1-1.4)), right bundle branch block (OR: 6.3 (5-7.7)), ventricular tachycardia (OR: 2.2 (1.9-2.6)), supraventricular tachycardia (OR: 1.6 (1.4-2)), and more commonly required pacemaker insertion (OR: 1.4 (1.3-1.7)) (p < 0.001 for all) compared to SM. This nationwide analysis evidenced that patients undergoing SM had higher in-hospital mortality and periprocedural complications than ASA; however, those undergoing ASA had more post-procedure conduction abnormalities and pacemaker implantation. The implications of these findings warrant further investigation regarding patient selection strategies for these therapies.

US trends of in-hospital morbidity and mortality for acute myocardial infarctions complicated by cardiogenic shock

BACKGROUND

There is limited real-world data highlighting recent temporal in-hospital morbidity and mortality trends for cases of acute myocardial infarction complicated by cardiogenic shock. The role of mechanical circulatory support within this patient population remains unclear.

METHODS

The US National Inpatient Sample database was sampled from 2011 to 2018 identifying 206,396 hospitalizations with a primary admission diagnosis of ST- or Non-ST elevation myocardial infarction complicated by cardiogenic shock. The primary outcomes included trends of all-cause in-hospital mortality, mechanical circulatory support use, and sex-specific trends for acute myocardial infarction complicated by cardiogenic shock (AMI-CS) over the study period.

RESULTS

The annual number of AMI-CS hospitalizations increased from 22,851 in 2011 to 30,015 in 2018 and in-hospital mortality trends remained similar (42.9 % to 43.7 %, ptrend < 0.001). The proportion of patients receiving any temporary MCS device decreased (46.4 % to 44.4 %). The use of intra-aortic balloon pump (IABP) decreased (44.9 % to 32.9 %) and the use of any other non-IABP MCS device increased (2.5 % to 15.6 %), ptrend<0.001. Sex-specific mortality indicate female in-hospital mortality remained similar (50.3 % to 51 %, ptrend<0.001), but higher than male in-hospital mortality, which increased non-significantly (38.8 % to 40.2 %, ptrend = 0.372).

CONCLUSIONS

From 2011 to 2018, hospitalizations for AMI-CS patients have increased in number. However, there has been no recent appreciable change in AMI-CS mortality despite a changing treatment landscape with decreasing use of IABPs and increasing use of non-IABP MCS devices. Further research is necessary to examine the appropriate use of MCS devices within this population.

A historical, evidence-based, and narrative review on commonly used dietary supplements in lipid-lowering

Dietary supplements augment the nutritional value of everyday food intake and originate from the historical practices of ancient Egyptian (Ebers papyrus), Chinese (Pen Ts'ao by Shen Nung), Indian (Ayurveda), Greek (Hippocrates), and Arabic herbalists. In modern-day medicine, the use of dietary supplements continues to increase in popularity with greater than 50% of the US population reporting taking supplements. To further compound this trend, many patients believe that dietary supplements are equally or more effective than evidence-based therapies for lipoprotein and lipid-lowering. Supplements such as red yeast rice, omega-3 fatty acids, garlic, cinnamon, plant sterols, and turmeric are marketed to and believed by consumers to promote "cholesterol health." However, these supplements are not subjected to the same manufacturing scrutiny by the Food and Drug Administration as pharmaceutical drugs and as such, the exact contents and level of ingredients in each of these may vary. Furthermore, supplements do not have to demonstrate efficacy or safety before being marketed. The holistic approach to lowering atherosclerotic cardiovascular disease risk makes dietary supplements an attractive option to many patients; however, their use should not come at the expense of established therapies with proven benefits. In this narrative review, we provide a historical and evidence-based approach to the use of some dietary supplements in lipoprotein and lipid-lowering and provide a framework for managing patient expectations.

In-hospital outcomes in unhoused patients with cardiogenic shock in the United States: Insights from The National Inpatient Sample 2011-2019

BACKGROUND

Unhoused patients face significant barriers to receiving health care in both the inpatient and outpatient settings. For unhoused patients with heart failure who are in extremis, there is a lack of data regarding in-hospital outcomes and resource utilization in the setting of cardiogenic shock (CS).

HYPOTHESIS

Unhoused patients hospitalized with CS have increased mortality and decreased use of invasive therapies as compared to housed patients.

METHODS

The National Inpatient Sample (NIS) database was queried from 2011 to 2019 for relevant ICD-9 and ICD-10 codes to identify unhoused patients with an admission diagnosis of CS. Baseline characteristics and in-hospital outcomes between patients were compared. Binary logistic regression was used to adjust outcomes for prespecified and significantly different baseline characteristics (p < .05).

RESULTS

We identified a weighted sample of 1 202 583 adult CS hospitalizations, of whom 4510 were unhoused (0.38%). There was no significant difference in the comorbidity adjusted odds of mortality between groups. Unhoused patients had lower odds of receiving mechanical circulatory support, left heart catheterization, percutaneous coronary intervention, or pulmonary artery catheterization. Unhoused patients had higher adjusted odds of infectious complications, undergoing intubation, or requiring restraints.

CONCLUSIONS

These data suggest that, despite having fewer traditional comorbidities, unhoused patients have similar mortality and less access to more aggressive care than housed patients. Unhoused patients may experience under-diuresis, or more conservative care strategies, as evidenced by the higher intubation rate in this population. Further studies are needed to elucidate long-term outcomes and investigate systemic methods to ameliorate barriers to care in unhoused populations.

Outcomes of Acute Myocardial Infarction in Female Patients With Type 1 Diabetes Mellitus

There is a paucity of data on acute myocardial infarction (AMI) outcomes for female patients with type 1 diabetes (T1DM) compared with men. The National Inpatient Sample Database was queried from 2011 to 2019 for relevant International Classification of Diseases, Ninth and Tenth Revision procedural and diagnostic codes. Hospitalizations with an admitting diagnosis of non-ST-elevation myocardial infarction or ST-elevation myocardial infarction were compared between male and female patients with T1DM. A multivariate logistic regression adjusting for baseline characteristics and primary diagnosis was performed. A p <0.001 was considered significant. A total of 50,020 hospitalizations for AMI in patients with T1DM were identified, of which 23,980 (47.9%) were women. The baseline characteristics are listed in Table 1. Women experienced similar rates of all-cause and inhospital mortality (5.0% vs 4.7%, p = 0.082). However, after adjusting for baseline characteristics and primary diagnosis, women had higher odds of mortality (adjusted odds ratio [aOR] 1.26, 95% confidence interval [CI] 1.15 to 1.38). Women were less likely to undergo cardiac catheterization (65.7% vs 68.2%; aOR 0.90, 95% CI 0.86 to 0.94) and coronary artery bypass grafting (5.6% vs 6.9%; aOR 0.76, 95% CI 0.70 to 0.82, p <0.001 for both). There was no difference in the use of percutaneous coronary intervention (41.0% vs 41.9%; aOR 1.01, 95% CI 0.97 to 1.05, p = 0.042). The female gender is not protective against AMI in patients with T1DM. Women with T1DM, on average, experience AMI at the same age as men, are less likely to undergo surgical revascularization, and have higher odds of mortality.

Impact of Chronic Heart Failure on Acute Pulmonary Embolism in-Hospital Outcomes (From a Contemporary Study)

There is a paucity of evidence on the impact of chronic heart failure (HF) on acute pulmonary embolism (PE) hospitalization outcomes. The aim of this study was to evaluate the in-hospital outcomes of patients with chronic HF and acute PE. A total of 1,391,145 hospitalizations with acute PE from the National Inpatient Sample Database from 2011 to 2019 were included. The database was queried for relevant International Classification of Diseases, Ninth and Tenth Revisions procedural and diagnostic codes. Baseline characteristics and in-hospital outcomes for patients with acute PE were compared in patients with and without a history of chronic HF. Multivariate logistic regression analyses were performed, adjusting for age, race, gender, and statistically significant co-morbidities between cohorts. A p value <0.001 was considered significant. Overall, the mean age was 65.2±16 years; 50.9% of patients were women, and 230,875 patients (16.6%) had chronic HF. The patients in the chronic HF cohort were predominantly older (mean age 69.0 vs 61.4 years) and male (49.9% vs 48.3%). In the multivariate model, chronic HF was associated with increased all-cause mortality (odds ratio [OR] 1.6, 95% confidence interval [CI], 1.57 to 1.63, 10.4% vs 5.7%), acute respiratory distress (OR 1.7, 95% CI 1.70 to 1.74, 39.5% vs 22.1%), cardiac arrest (OR 1.4, 95% CI 1.40 to 1.49, 3.9% vs 2.2%), and cardiogenic shock (OR 3.0, 95% CI 2.85 to 3.06, 4.2% vs 1.2%). All p values were <0.001. In conclusion, patients with PE and chronicHF are associated with increased in-hospital complications compared with patients with PE and without chronic HF. Prospective studies are needed to evaluate optimal management strategies in this population at high risk.

Temporary Mechanical Circulatory Support: Left, Right, and Biventricular Devices

Temporary mechanical circulatory support (MCS) encompasses a wide array of invasive devices, which provide short-term hemodynamic support for multiple clinical indications. Although initially developed for the management of cardiogenic shock, indications for MCS have expanded to include prophylactic insertion prior to high-risk percutaneous coronary intervention, treatment of acute circulatory failure following cardiac surgery, and bridging of end-stage heart failure patients to more definitive therapies, such as left ventricular assist devices and cardiac transplantation. A wide variety of devices are available to provide left ventricular, right ventricular, or biventricular support. The choice of a temporary MCS device requires consideration of the clinical scenario, patient characteristics, institution protocols, and provider familiarity and training. In this review, the most common forms of left, right, and biventricular temporary MCS are discussed, along with their indications, contraindications, complications, cannulations, hemodynamic effects, and available clinical data.

The association of pre-transplant atrial fibrillation with in-hospital outcomes in patients undergoing orthotopic liver transplantation: A propensity score matching analysis

INTRODUCTION

In this study, we sought to evaluate the prevalence and association of pre-transplant atrial fibrillation (AF) on 30-day postoperative outcomes in patients undergoing orthotopic liver transplant (OLT).

METHOD

The National Inpatient Sample Database was queried from 2011 to 2017 for relevant ICD-9 and ICD-10 procedural and diagnostic codes. Baseline characteristics and in-hospital outcomes were compared in patients who underwent OLT with AF and those without.

RESULTS

Among 45,357 patients who underwent OLT, women made up 35.8% of the overall population. The prevalence of AF before transplant was 2932 (6.5%) with a trend toward increasing prevalence, with an average annual change rate of 4.19%. Applying propensity score matching to control for potential confounding factors, there was no association between pre-transplant AF and in-hospital mortality in patients undergoing OLT, however there was a higher incidence of perioperative complications including: acute kidney injury, ventricular tachycardia, major bleeding, blood product transfusion, and septic shock.

CONCLUSION

In patients undergoing OLT, pre-transplant AF is increasing in prevalence and appears to be associated with similar in-hospital mortality but worse perioperative outcomes. Greater emphasis should be placed on AF in the preoperative cardiovascular risk stratification of patients undergoing OLT.

The association of racial differences with in-hospital outcomes of patients admitted for sinus node dysfunction

Background

The impact of race and its related social determinants of health on cardiovascular disease outcomes has been well documented. However, limited data exist regarding the association of race with in-hospital outcomes in patients admitted for sinus node dysfunction (SND).

Objective

To evaluate whether racial disparities exist in outcomes for patients hospitalized with a primary diagnosis of SND.

Methods

The National Inpatient Sample was queried from 2011 to 2018 for relevant ICD-9 and ICD-10 diagnosis and procedure codes. Baseline characteristics and in-hospital outcomes in patients with a primary diagnosis of SND were compared among White and non-White patients. A multivariate logistic regression model was used to adjust for potential confounding factors and statistically significant comorbidities between both cohorts.

Results

We identified 655,139 persons admitted with a primary diagnosis of SND, 520,926 (79.5%) of whom were White. Non-White patients had significantly higher all-cause mortality, length of stay, and total hospital cost. There were lower odds of pacemaker insertion (adjusted odds ratio [aOR] 1.13 [95% confidence interval (CI) 1.11–1.15]), temporary transvenous pacing (aOR 1.15 [95% CI 1.11–1.22]), and cardioversion (aOR 1.50 [95% CI 1.42–1.58]) in non-White patients. A subgroup analysis was performed and non-Hispanic Black race was predictive of a decreased odds of pacemaker insertion, cardioversion/defibrillation, and temporary transvenous pacing.

Conclusion

Significant differences of in-hospital outcomes exist between White and non-White patients with SND. These findings appeared to be primarily driven by disparities in non-Hispanic Black patients. Increased recognition and focused efforts to mitigate these disparities will improve the care of underrepresented populations treated for SND.

5-Aminolevulinic acid patch (Alacare) photodynamic therapy for actinic cheilitis: data from a prospective 12-month follow-up study on 21 patients

Background

Actinic cheilitis (AC) is a variant of actinic keratosis (AK) affecting the lips and caused by chronic ultraviolet exposure.

Objective

Alacare is a self‐adhesive, skin‐coloured 5‐aminolaevulinic acid patch that has been developed for use in photodynamic therapy (PDT) of mild‐to‐moderate AK. Based on promising preliminary results in the treatment of AC with Alacare patch PDT, we decided to extend our previous investigation to gain more data on the efficacy, tolerability, safety and cosmetic outcome of Alacare patch PDT for AC.

Methods

Twenty‐one patients with a clinical diagnosis of mild‐to‐moderate AC were included in the study and subjected to one single session of PDT. After occlusion with the Alacare patch for 4 h, the AC lesions were illuminated for 10 min with red light at a dose of 37 J/cm². All patients received local anaesthesia prior to illumination. Additionally, all lesions were cooled during PDT with a cold air blower. PDT‐induced pain and skin phototoxicity were monitored during and up to 7 days after PDT. Clinical assessment of efficacy, cosmetic outcome and global patient satisfaction was performed at 3, 6 and 12 months after treatment.

Results

Nineteen patients completed the study. Three months after PDT, 17 patients (89.5%) had achieved complete remission. Of these, one patient presented with recurrence of AC at the 6‐month follow‐up, whereas all other patients remained in remission until the end of the observation period. The complete clinical cure rate at 1 year after a single Alacare patch PDT thus was 84.2%. Pain during illumination and the phototoxic skin reaction were in general mild to moderate. The cosmetic outcome was excellent.

Conclusion

The present prospective study on Alacare patch PDT for AC confirms its high clinical efficacy, good tolerability and favourable cosmetic effects. Alacare patch PDT should be considered as a valid treatment option for patients with AC.

An inhibitor-resistant histone deacetylase in the plant pathogenic fungus Cochliobolus carbonum

We have partially purified and characterized histone deacetylases of the plant pathogenic fungus Cochliobolus carbonum. Depending on growth conditions, this fungus produces HC-toxin, a specific histone deacetylase inhibitor. Purified enzymes were analyzed by immunoblotting, by immunoprecipitation, and for toxin sensitivity. The results demonstrate the existence of at least two distinct histone deacetylase activities. A high molecular weight complex (430,000) is sensitive to HC-toxin and trichostatin A and shows immunoreactivity with an antibody against Cochliobolus HDC2, an enzyme homologous to yeast RPD3. The second activity, a 60,000 molecular weight protein, which is resistant even to high concentrations of well-known deacetylase inhibitors, such as HC-toxin and trichostatin A, is not recognized by antibodies against Cochliobolus HDC1 (homologous to yeast HOS2) or HDC2 and represents a different and/or modified histone deacetylase which is enzymatically active in its monomeric form. This enzyme activity is not present in the related filamentous fungus Aspergillus nidulans. Furthermore, in vivo treatment of Cochliobolus mycelia with trichostatin A and analysis of HDACs during the transition from non-toxin-producing to toxin-producing stages support an HC-toxin-dependent enzyme activity profile.

Comparative analysis of HD2 type histone deacetylases in higher plants

Zea mays (L.) histone deacetylase HD2 was identified as a new type of histone deacetylase (HDAC) unrelated to the well-known Rpd3p and Hdalp families but with sequence homology to peptidyl-prolyl cis-trans isomerases (PPIases). Here we show that HD2 is a multigene family with highly related members in various plant species. Gene analysis revealed a similar exon/intron structure in Arabidopsis thaliana (L.) Heynh. and Z. mays, and most of the sequences analyzed were demonstrated to possess an intron of the very rare AT-AC type.

Characterization of two putative histone deacetylase genes from Aspergillus nidulans

In eukaryotic organisms, acetylation of core histones plays a key role in the regulation of transcription. Multiple histone acetyltransferases (HATs) and histone deacetylases (HDACs) maintain a dynamic equilibrium of histone acetylation. The latter form a highly conserved protein family in many eukaryotic species. In this paper, we report the cloning and sequencing of two putative histone deacetylase genes (rpdA, hosA) of Aspergillus nidulans, which are the first to be analyzed from filamentous fungi. Hybridization with a chromosome-specific cosmid library of A. nidulans allowed the localization of rpdA to chromosome III and hosA to chromosome II, respectively. PCR analyses and Southern hybridization experiments revealed that no further members of the RPD3 family are present in the genome of the fungus. Although sequence alignment displays significant amino acid similarity to other eukaryotic RPD3-type deacetylases, the deduced RPDA sequence reveals an unusual 200-amino acid extension at the C-terminus. Expression of both genes was determined by RNA blot analysis. Treatment of the cells with trichostatin A (TSA), a potent inhibitor of HDACs, was found to stimulate expression of rpdA of A. nidulans.
