30-day readmission following urgent and elective transcatheter aortic valve replacement: A Nationwide Readmission Database analysis.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is being increasingly used for decompensated severe symptomatic aortic stenosis. Data on urgent and elective TAVR readmission is scarce in the literature. Here, we have performed a retrospective cohort study with the Nationwide Readmission Database of 2016 to identify the rate of 30-day all-cause readmission, common causes of readmission, and distribution of morbidity in index admission and readmission after urgent and elective TAVR. METHODS: We used International Classification of Diseases, Tenth Revision codes (02R.F38H, 02R.F38Z, 02R.F48Z) for identification of all TAVR procedures done in 2016 in patients >18 years old. We found 8379 patients who underwent urgent TAVR and 32,006 patients who underwent elective TAVR in 2016. RESULT: The mean age of patients undergoing urgent TAVR was 79 ± 9.97 years with 44.6% women. The mean age of patients undergoing elective TAVR was 80.7 ± 8.25 years with 46.2% women. We found the 30-day all-cause readmission rate of 15.5% and 9.5% in patients undergoing urgent and elective TAVR, respectively (p < 0.001). The cardiac cause was the predominant cause of readmission in both groups (43.77% vs. 42.11%, p = 0.57), followed by pulmonary cause, gastrointestinal (GI) cause, and renal cause. Among cardiac causes, congestive heart failure (CHF) was predominant cause of readmission and was similar in both groups (18.73 in urgent TAVR vs. 15.73 in elective TAVR, p = 0.12). CONCLUSION: We found that the all-cause 30-day readmission rate was higher in patients who had undergone urgent TAVR. Further studies are needed to better understand this difference.

Outcomes of diverticulitis in patients with tobacco smoking: a propensity-matched analysis of nationwide inpatient sample.

BACKGROUND: Recent data shows a significantly increased risk of diverticulosis among smokers. There is limited data on the association between tobacco smoking and diverticulitis. We aim to determine in-hospital outcomes, length of hospital stay, and resource utilization in a contemporary cohort of diverticulitis patients based on tobacco smoking status. METHODS: A retrospective analysis was performed by utilizing the National Inpatient Sample database (2016 and 2017) and the International Classification of Diseases, Tenth Revision codes to identify the patients with the principal diagnosis of diverticulitis and smoking. We assessed all-cause in-hospital mortality, morbidity, length of hospital stay (LOS), and total costs between propensity-matched groups of tobacco smokers vs. nonsmokers with diverticulitis. RESULTS: We identified 442,273 diverticulitis patients, of whom 96,864 were tobacco smokers, and 345,409 were nonsmokers. Between the two groups, in-hospital mortality was not significant (OR 1.09, 95% CI 0.38-2.6; P = 0.98). Tobacco smokers with diverticulitis have higher odds of lower gastrointestinal bleeding (LGIB) (OR 1.6, 95% CI 1.4-3.8; P = 0.01), peritonitis (OR 1.5, 95% CI 1.9-3.3; P = 0.00), intestinal obstruction (OR 1.6, 95% CI 2.8-7.6; P = 0.00), sepsis (OR 2.1, 95% CI 1.05-4.4; P = 0.03), and shock requiring vasopressor (OR 1.5, 95% CI 1.2-2.2; P = 0.00). In tobacco smokers with complicated diverticulitis, there were higher odds of LGIB (OR 1.4, 95% CI 1.2-1.6; P = 0.00), sepsis (OR 2.1, 95% CI 1.05-4.4; P = 0.03), and colectomy (OR 1.2, 95% CI 1.1-1.2; P = 0.00). In-hospital mortality was not significant in smokers with complicated diverticulitis (OR 1.2, 95% CI 0.78-1.9; P = 0.3). CONCLUSIONS: In this propensity-matched analysis, there was no difference in in-hospital mortality between tobacco smokers vs. nonsmokers with diverticulitis. Smoking has been associated with an increased incidence of complications in diverticulitis with a higher length of hospital stay and resource utilization.

Skin Prick Test Positivity in Chronic Urticaria.

BACKGROUND: Skin prick tests identify allergens for chronic urticaria. The objective of this study was to determine skin prick test positivity in patients with chronic urticaria visiting skin outpatient department in one of the tertiary referral centre of Nepal. METHODS: This was a hospital based cross-sectional study conducted at Department of Dermatology and Venereology, Tribhuvan University Teaching Hospital. All patients of chronic urticaria aged more than 16 years were taken into study and were prick tested with seven groups of 21 allergens, taking normal saline as negative control and histamine as positive control as per the standard protocol by the Global Allergy and Asthma European Network. Frequency of positivity to each allergen was assessed. RESULTS: Out of 62 patients of chronic urticaria enrolled in the study, 52% were females and 48% were males. Overall, 71% were positive for at least one allergen. The most common allergens which tested positive included Dermatophagoides farinae (50%), Cotton dust (17.7%), Mosquito (16%), hay dust (14.5%), Cladosporium herbarum (14.5%), Candida albicans (12.9%), Parthenium hysterophorus (9.6%), House fly (9.6%), Soya bean (9.6%) and fish sardine (8%). Out of all these patients, 55% patients showed positivity to more than one allergens. CONCLUSIONS: A significant proportion of cases with chronic urticaria demonstrated sensitivity to various allergens. Skin prick test can be considered as important diagnostic procedure in cases of chronic urticaria in our population.

Sex Differences in In-Hospital Outcomes of Transcatheter Aortic Valve Replacement.

Since the introduction of transcatheter aortic valve replacement (TAVR), there has been a paradigm shift in the management of severe aortic stenosis. While women represent almost half of the patients undergoing TAVR, there are limited data on sex-based comparisons in hospital outcomes and predictors of mortality in women and men. The National Inpatient Sample database from 2012 to 2015 was used to identify TAVR using international classification of diseases-9 clinical modification procedure codes 35.05 and 35.06. We identified 61,239 patients who underwent TAVR between 2012 and 2015. After adjusting for potential confounders, women had higher odds of all-cause mortality as compared to men [odds ratio (OR) 1.25, 95% confidence interval (CI): 1.01-1.54; P = 0.036]. Moreover, women had significantly increased odds of cardiac complications [OR 2.41, 95% CI: 1.67-3.49; P ≤ 0.01], respiratory complications [OR 1.20 95% CI: 1.07-1.34; P = 0.001], major hemorrhage requiring transfusion [OR 1.51, 95% CI: 1.37-1.67; P ≤ 0.001], neurological complications [OR 1.38, 95% CI: 0.95-1.99; P = 0.08], need for vasopressor treatment [OR 1.33, 95% CI: 1.01-1.75; P = 0.04], and vascular complications [OR 1.73, 95% CI: 1.19-2.52; P = 0.004]. On the contrary, the odds of pacemaker requirement [OR 0.85, 95% CI: 0.75-0.97; P = 0.02], and acute kidney injury [OR 0.80, 95% CI: 0.71-0.91; P = 0.001] were significantly lower in women. Among patients undergoing TAVR, women were more likely to have in-hospital complications and mortality as compared with men. Further studies are needed to identify the discrepancy in in-hospital outcomes with sex-specific factors being considered.

Does Insurance Effect the Outcome in Patients With Acute Coronary Syndrome?: An Insight from the Most Recent National Inpatient Sample.

Several studies have shown disparities in outcome in the patients with Acute coronary syndrome (ACS) based on several factors. Treatment might differ based on insurance type. Therefore, we retrospectively analyzed National Inpatient Sample (NIS 2016) data to identify the impact of different types of insurances on mortality outcome in patients admitted with ACS. ICD-CM-10 codes were used to identify hospital discharges with a principal diagnosis of ACS. Observations were stratified based on insurance (Medicare, Medicaid, Private, and No insurance). Primary and secondary outcomes were in-hospital mortality, length of stay and total cost. Any potential confounders were adjusted using multivariate logistic regression. STATA/IC 15.1 Stata Corp LLC was used for analysis. A total of 8,01,195 hospitalizations with the primary diagnosis of ACS were identified, of which 59.2% had Medicare, 9.72% had Medicaid, 26.8% had Private insurance, and 4.3% had no insurance. Higher odds of mortality were seen in the patients with Medicare, Medicaid, and Noninsured group. Adjusted Odds ratio for mortality in Medicare was 1.01 (confidence interval [CI]: 0.94-1.1; P = 0.65), in Medicaid was 1.16 (CI: 1.03-1.30; P = 0.01) and in uninsured group was 1.46 (CI: 1.26-1.69; P ≤ 0.01). However, the patients with private insurance adjusted odds ratio for mortality were 0.77 (CI: 0.70-0.84; P ≤ 0.01) compared to the patients with other insurance groups. Above results show that the disparity exists in the outcome of patients admitted with ACS based on their insurance types, particularly for Medicaid patients. We need further studies to understand the root cause of this disparity.

Primary cutaneous actinomycosis: a diagnosis consideration in people living with HIV/AIDS.

BACKGROUND: Owing to similar clinical presentations, as of cutaneous disease of different etiologies, and extreme rarity in the global incidence; primary cutaneous actinomycosis often remains as diagnostic challenges. CASE PRESENTATION: Herein, we describe a case of primary cutaneous actinomycosis, erroneously treated as cutaneous tuberculosis, in a patient living with AIDS. On clinical examination, the characteristic lesion, resembling cutaneous tuberculosis, observed on the dorsum of a left leg. No other lesion elsewhere on the body was observed, however. Cytological examinations of the stabbed biopsy were negative for malignant cells; although hyper-keratosis and mild-acanthosis of epidermis, acute inflammatory infiltrates comprising plasma cell, macrophages and neutrophils were observed in the upper and mid dermis. The pus aspirated from lesion grew a molar tooth, adherent colonies in microaerophilic condition. Further, identifications and susceptibility pattern against recommended antibiotics were assessed as per the CLSI (Clinical and Laboratory Standard Institute) guidelines. Subsequently, the case was then, diagnosed as primary cutaneous actinomycosis. Radiographic imaging of abdomen and lungs were normal; no feature of disseminated actinomycosis seen. Penicillin G followed by Penicillin V, was prescribed for 12 months. The patient underwent progressive changes and no relapse noted on periodic follow-up. CONCLUSION: The case underscores cutaneous actinomycosis requires a diagnosis consideration, especially in People Living with HIV/AIDS (PLHA), where myriad of opportunistic cutaneous infections are common.

Cutaneous Tuberculosis: Clinicopathologic Arrays and Diagnostic Challenges.

The clinicopathological manifestations of cutaneous tuberculosis are diverse. The precise diagnosis is often overlooked, due to clinical presentations as those of cutaneous diseases with different etiology and the relative paucity of the pathogens in the lesions. Meanwhile, almost all of the diagnostic methods confer lower sensitivity and specificities which augments further diagnostic challenges. This article revises the current scenario of the disease's physiopathology and underscores clinicopathological challenges, due to multifaceted presentations of cutaneous tuberculosis, in the diagnosis.
