COVID-19 Isolation and Quarantine Guidelines for Older Adults in Nursing Homes.

The COVID-19 pandemic poses an ever-increasing threat to older Americans, especially those in nursing homes. The compact nature of these facilities and the morbidities shared by this population make them susceptible to the virus and its symptoms. Because of this, the CDC has published guidelines directed at isolation and quarantine measures specifically created to protect this patient population. These measures are comprehensive and provide examples and management of situations, such as admissions and outbreaks, that these facilities must deal with and be ready to face on a regular basis. In this review, we discuss the guidelines for isolation and quarantine as it pertains to the nursing home population, and some of the unintended effects these protocols may have on this population.

A Comprehensive Review of COVID-19 Associated Neurological Manifestations.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing COVID-19 utilizes the angiotensin-converting enzyme 2 (ACE-2) receptor of cells in order to gain entry and continue infection. Recent literature has focused on acute respiratory distress syndrome (ARDS) and other associated pulmonary complications; however, only a scarce amount of literature exists on neurological complications. Such complications also pose a high morbidity in these patients. The exact pathogenesis of nervous system involvement by COVID-19 still remains poorly understood. The aim of this article is to review the neurological symptoms seen in COVID-19 infection and discuss the probable pathogenesis, management and outcome of associated neurological complications.

The Economic Implications of COVID-19 in the United States.

The novel coronavirus disease 2019 (COVID-19) first reported in Wuhan, China, in 2019 has evolved into a pandemic and public health emergency, leading to extensive fatalities and halting global economies. Older adults have emerged as a critically vulnerable population as earlier data suggests a disproportionately increased incidence of COVID-19 in this population, as well as worse health outcomes. Disease attenuating behaviors such as social distancing has been encouraged and mandated across different countries leading to downstream economic ramifications. This paper seeks to outline the economic implications of COVID-19 in the U.S. (particularly in terms of vocational, retail, and service industries), highlighting the role of nursing homes in disease dissemination. We also discuss potential costs associated with COVID-19 management focusing on the senior population who rely on Medicare benefits for health insurance.

COVID-19: Catastrophic Cause of Acute Lung Injury.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak that began in 2019 and spread rapidly across the globe has been observed to cause acute lung injury and multiorgan system failure. While common symptoms are flu-like, this population has been observed to decompensate at an alarmingly rapid rate to severe hypoxia. SARS-CoV-2 infects host cells by targeting the angiotensin-converting enzyme 2 (ACE2) receptor, which is present on endothelial cells in the lung, heart, kidney, and gastrointestinal tissue. The pathophysiology of acute respiratory distress syndrome (ARDS) in SARS-CoV-2 infection has a component of lung perfusion dysregulation and is described as a "cytokine storm" that causes increased vascular permeability and disease severity. Older adults and those with comorbid conditions, particularly hypertension, diabetes, and history of ischemic heart disease, are especially vulnerable. These high-risk populations are often on angiotensin-modulating therapies, which are theorized to increase ACE2 expressivity, but current evidence for or against discontinuation is equivocal. The standard for SARS-CoV-2 testing is through reverse transcription polymerase chain reaction, which has presented problems due to low sensitivity and possible co-infection with other pathogens. Treatment for ARDS in the setting of SARS-CoV-2 should follow pre-established goals of care and the wishes of the patient and family members or caregivers and consider the high risk for polypharmacy, cognitive decline, malnutrition, and depression, particularly in older adults. Treatment recommendations have outlined ventilation goals to minimize further lung injury. Compassionate use of pharmacologic therapies such as remdesivir has shown promise, and further clinical trials of anticytokine agents are underway.

Gastrointestinal Manifestations of COVID-19: A Review of What We Know.

Background: The coronavirus disease 2019 (COVID-19) is not just a disease of the respiratory system. The virus can affect the gastrointestinal (GI) tract as well. Recognizing the various manifestations in every organ system is important because these manifestations can contribute to community-based transmission. Methods: We outline the evidence of the pathophysiology of COVID-19 in the GI tract, the effects of the virus on the gut and liver, the presence of the virus in stool samples, and the potential for fecal-oral transmission of COVID-19. Most of the literature sources used in this paper are case studies from China following the surge of COVID-19 infection. Results: In patients with COVID-19, GI symptoms such as anorexia, nausea, vomiting, diarrhea, and abdominal pain have presented in conjunction with respiratory symptoms such as fever, shortness of breath, and cough. Evidence also shows acute hepatocellular injury, indicated by elevated liver enzymes such as alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase. Fecal-oral transmission of COVID-19 is suspected because of the presence of COVID-19 RNA in stool samples of COVID-19-positive patients. Conclusion: Even without the presence of respiratory symptoms, several GI symptoms are associated with COVID-19 infection, as well as possible fecal-oral transmission. Therefore, COVID-19 infection should be considered for patients presenting with primarily GI symptoms.

Papering over the cracks: COVID-19's amplification of the failures of employer-based health insurance coverage.

Background: COVID-19 has altered numerous lives and accounted for significant mortality and morbidity throughout the world and, especially, the USA. During the pandemic, from mid-March to July 2020, around one-fourth of the US population filed for unemployment benefits. Objective: In this article, we discuss the economic ramifications exposed in the American healthcare system's current model by the COVID-19 crisis. Methods: In this review, we analyze 18 articles to look at how access to health insurance has affected how Americans receive medical care during the coronavirus pandemic. Results: The large-scale job losses related to the pandemic translates directly into millions of Americans also losing employer-sponsored health insurance (ESI) coverage. With the pandemic disproportionately affecting minority populations, these communities now bear the additional toll of not receiving appropriate care. Conclusion: Due to the pandemic, it is probable that a significant portion of Americans that are uninsured are less likely to seek medical care for COVID-19 symptoms. While the disease can manifest as a mild respiratory illness in most, others can experience more severe disease and require acute, intensive medical care. The lack of health insurance in this instance can be potentially fatal. Given that COVID-19 has disproportionately affected minority communities across the USA, it is important to highlight the correlation between access to medical care and COVID-19 infection rates. Communities that are of lower socioeconomic status are less likely to have health insurance and follow up with medical care due to out-of-pocket costs, which in turn leads to a higher case fatality rate due to COVID-19.

Cardiology and COVID-19: do we have sufficient information?

COVID-19 caused by severe acute respiratory syndrome coronavirus 2, which originated in Wuhan (China), transformed into a worldwide pandemic. The short span associated with the spread of the virus and its varied manifestations presents a steep learning curve for many clinicians on the front-line of treatment. Cardiology is one such affected area. This paper details the signs and symptoms of cardiovascular disease resulting from COVID-19, including its proposed pathophysiology, signs and symptoms, treatments and outcomes under investigation. The consensus is that COVID-19 patients with cardiovascular injury have a shorter duration from symptom onset to deterioration, higher mortality and higher prevalence in older populations. Diagnosis and intervention for patients with underlying cardiovascular comorbidities is critical.

COVID-19 and Older Adults: What We Know.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel virus that causes COVID-19 infection, has recently emerged and caused a deadly pandemic. Studies have shown that this virus causes worse outcomes and a higher mortality rate in older adults and those with comorbidities such as hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and chronic kidney disease (CKD). A significant percentage of older American adults have these diseases, putting them at a higher risk of infection. Additionally, many adults with hypertension, diabetes, and CKD are placed on angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers. Studies have shown that these medications upregulate the ACE-2 receptor, the very receptor that the SARS-CoV-2 virus uses to enter host cells. Although it has been hypothesized that this may cause a further increased risk of infection, more studies on the role of these medications in COVID-19 infections are necessary. In this review, we discuss the transmission, symptomatology, and mortality of COVID-19 as they relate to older adults, and possible treatments that are currently under investigation.

Approach to critical illness myopathy and polyneuropathy in the older SARS-CoV-2 patients.

One of the major concerns of the health care community and the public surrounding the SARS-CoV-2 pandemic is the availability and use of ventilators. Unprecedented surges of patients presented to intensive care units across the country, with older adults making up a large proportion of the patient population. This paper illustrates contemporary approaches to critical illness myopathy (CIM), critical illness polyneuropathy (CIP), and critical illness polyneuromyopathy (CIPNM) in older patients, including incidence, risk factors, mechanisms for pathology, diagnosis, contemporary treatment approaches, and outcomes. We hope that the following analysis may help educate clinicians and ultimately decrease the duration of the mechanical ventilation required by these patients, resulting in improved clinical outcomes and an increase in ventilator availability for other patients in need.

Vitrectomy for Epiretinal Membranes and Macular Holes in Uveitis Patients.

PURPOSE: Macular pathology, including macular holes (MHs), epiretinal membranes (ERMs), and macular edema, is a cause of irreversible vision loss in the setting of uveitis. Medical management involves corticosteroids, immunomodulatory medications, and biologics to control inflammation. Pars plana vitrectomy (PPV) has been suggested as a therapy for uveitis, with reports of reduced inflammation and decreased dependence on medication postoperatively. Currently, PPV is reserved for retinal detachments, vitreous opacities, and ERMs, causing vitreomacular traction. However, little is known about the visual outcomes of PPV with ERM peel for MH, or in ERM without evidence of traction in the context of uveitis. METHODS: Review of small case series and case reports support both conservative medical treatment and vitrectomy, independently, and in combination, in the management of macular pathology in the setting of uveitis. RESULTS AND CONCLUSIONS: Further studies are required to study uveitic etiologies separately with respect to visual outcomes after vitreoretinal surgery and medical management.
