Nationwide analysis of neuromyelitis optica in systemic lupus erythematosus and Sjogren’s syndrome
Objective Neuromyelitis optica (NMO), also known as Devic’s disease, is a rare inflammatory demyelinating disorder causing myelitis and optic neuritis. While there have been reports of systemic lupus erythematosus (SLE) and primary Sjogren’s syndrome (SS) occurring with NMO, a formal association is not established. We aimed to investigate the occurrence of NMO in SLE and SS patients and study the clinical characteristics and outcomes of NMO and SLE/SS hospitalizations utilizing the national inpatient sample (NIS) database. Methods The NIS database from 2016 to 2019 was used to extract data. Adult hospitalizations with the principal or secondary diagnosis of NMO were included. We classified NMO patients with and without concomitant diagnosis of SLE or Sjogren’s syndrome. We evaluated and compared the clinical characteristics and outcomes of NMO hospitalizations with and without SLE or Sjogren’s syndrome. STATA17 was used for data analysis. We also calculated the odds ratio of NMO in SLE and Sjogren’s syndrome. Results There were a total of 16,360 adult hospitalizations with the principal or secondary discharge diagnosis of NMO. Among all NMO hospitalizations, 1425 (8.71%) had the primary or secondary diagnosis of SLE or SS. The odds of NMO in SLE and Sjogren’s syndrome were noted to be 12.29 and 5.56, respectively. NMO with SLE/SS group had higher proportion of females (89.82% vs 79%, P value < 0.001), African Americans (56.63% vs 38.28, P value < 0.001), and Asians (5.73% vs 3.25, P value 0.04). The Charlson comorbidity index was higher for NMO-SLE/SS overlap (2.44 vs 1.28, P value < 0.001). There was no significant difference in overall mortality rates of both groups (2.11% vs 1.2%, P value 0.197). There were significantly higher reported seizures (14.73% vs 6.05, P value < 0.001) and paraplegia (21.75% vs 13.93%, P value < 0.001) in NMO-SLE/SS patients. These patients also had a longer length of stay in comparison to the reference group (7 vs 5 days, P value < 0.001) as well as higher total charges. Conclusions NMO patients had a 12-fold higher risk of SLE and 5-fold higher risk of Sjogren’s disease when compared to general population. Patients with overlap of NMO and SLE or Sjogren’s were predominantly women and were more likely to be African-American. Co-existence of these autoimmune disorders was associated with poor prognosis in terms of higher morbidity for patients and increased health care burden. Key Points • NMO is a rare autoimmune disease seen predominantly in women in the middle age group with low overall mortality. • SLE and Sjogren’s have increased odds of NMO in comparison to general population. • NMO patients have high rates of several complications such as paraplegia, quadriplegia, seizures, blindness, sepsis, and respiratory failure with even higher rates of seizures and paraplegia in those with concomitant SLE or Sjogren’s.

Systemic Lupus Erythematosus: An Overview of the Disease Pathology and Its Management
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with varied natural history and multisystemic involvement. The pathogenesis is multifactorial and complex precipitating the formation of autoantibodies. One of the main factors in SLE is the interaction between environmental triggers and genetic factors. Genome-wide association study technology has led to the identification of more than 80 loci which produce key proteins that lead to small pathophysiological changes and are associated with SLE. There has been an improvement in the management of the disease with newly standardized scores that have been validated in assessing disease activity and quality of life, and have helped in clinical care as well as research. The last five decades have seen a marked improvement in the prognosis of SLE, thanks to better general care and the development of newer immunosuppressive drugs, more specifically biological agents.

The Prevention and Management of Contrast-induced Acute Kidney Injury: A Mini-review of the Literature
Contrast-induced acute kidney injury, also called contrast-induced nephropathy, is one of the main causes of acute renal failure/acute kidney injury (AKI) in hospitalized patients within 48 to 72 hours of contrast media administration during various radiologic procedures. Several factors can be responsible for contrast-induced acute tubular necrosis (ATN); however, patient and procedure-related factors play the lead role in determining the development of contrast-induced nephropathy. There is no definitive treatment and hydration remains the mainstay preventive strategy. This article will review the incidence, criteria for definitive diagnosis, and an effective approach on how to prevent contrast-induced nephropathy in a clinical setup.

American Heart Association High Blood Pressure Protocol 2017: A Literature Review
Hypertension is the most prevalent clinical symptom arising from various cardiovascular disorders. Likewise, it is considered a precursor or sequelae to the development of acute coronary artery disease and congestive heath failure (CHF). Hypertension has been considered a cardinal criterion to determine cardiovascular function. According to the World Health Organization (WHO) global observatory data, hypertension causes more than 7.5 million deaths a year, about 12.8% of the total human mortality. Similarly, the Center for Disease Control (CDC) states that 35% of the American adults have been estimated to have a persistently high blood pressure, which makes it about one in every three adults. Hypertension is a modifiable symptom that can be managed through pharmacological and non-pharmacological methods and standard protocols set forth by the American Heart Association (AHA). With new findings from various clinical trials related to the management of hypertension, new developments and recommendations have been made to update the previously established protocols for hypertension. This article aims to discuss and dissect the modern updates of hypertension management as comprehensively elaborated in the 2017 Hypertension Clinical Practice Guidelines.

Management of Orthostatic Hypotension: A Literature Review
In the older population, especially the hospitalized patients who are prone to dehydration and hypovolemia, orthostatic hypotension (OH) presents as a debilitating disease. How different pharmacological and non-pharmacological interventions affect the incapacitating symptoms (falls and episodes of syncope), morbidity, and mortality related to OH has become a topic of debate. OH can predispose to ischemic heart disease (IHD). A non-pharmacological approach consisting of mobilization, early lifestyle changes, and therapeutic maneuvers is the first choice in the management of these patients. Individuals with persistent symptoms require pharmaceutical therapy to increase blood volume and peripheral vascular resistance. This article summarizes the management of OH that is vital to cope with the needs of the growing geriatric populations.

Neurogenic Stunned Myocardium: A Literature Review
Neurogenic stunned myocardium (NSM) is defined as the occurrence of cardiac abnormalities due to neurological events such as stroke, seizures, etc. These events lead to dysfunction of the autonomic nervous system (ANS) and ultimately cause injury to the myocardium. The clinical features seen in NSM include elevated troponin level, left ventricular dysfunction, and changes on the electrocardiogram (ECG). However, these features are also seen in Takotsubo cardiomyopathy as well as in an acute coronary syndrome (ACS). Hence, diagnosing the condition by clinical presentation alone is difficult. Thus, a patient of NSM who is at increased risk of developing coronary heart disease may require invasive procedures such as cardiac catheterization to rule out ACS. This review aims at raising awareness about NSM among physicians so that management of patients can be individualized.
