RESUMO
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.
RESUMO
Plasma cell disorders including plasmacytomas and multiple myeloma (MM) are exquisitely radiosensitive, and thus, radiation therapy (XRT) is used effectively in their management. The role of XRT in the setting of novel MM therapeutics has not been explored. The 2016 National Cancer Database (NCDB) for MM with patients diagnosed between 2004 and 2013 was studied. Association between utilization of XRT as part of initial therapy and patient, disease, or treating facility characteristics was studied. A total of 111,281 cases with 91.6% MM, 7% osseous plasmacytoma (PLA-O), and 1.4% extramedullary plasmacytoma (PLA-E) were identified. XRT was utilized as part of initial therapy in 25.4% cases, including 69.3% of PLA-O, 60% of PLA-E, and 21.5% of MM patients. Patients with PLA-E and MM were significantly less likely to receive XRT as compared to PLA-O (p < 0.001). A significantly decreased use of XRT was noted over time (p < 0.001), and for advancing patient age (p < 0.001), women (p < 0.001), and blacks (p < 0.001), and with increasing income (p = 0.015). Patients with Medicare were less likely to receive XRT (OR 0.86, 95% CI 0.78, 0.94) as compared to uninsured as were those with initial treatment at academic or high-volume facilities and facilities performing stem cell transplant. There was overall decreased utilization of XRT in recent years, possibly due to advent of efficacious systemic agents for MM therapy, with a higher XRT utilization for plasmacytomas. Patterns of XRT use need to be explored prospectively, so that uniform standards of healthcare delivery can be maintained and treatment heterogeneity can be minimized.

INTRODUCTION: Despite significant improvements in multiple myeloma (MM) treatment modalities, patient mortality early in the course of disease has been identified as a persistent phenomenon with variable reported rates and causes. Trends in early mortality over time have not been clearly defined. PATIENTS AND METHODS: The Surveillance Epidemiology and End Results (SEER) database was used to identify adult patients with MM between 1975 and 2015. Association of available sociodemographic factors with all-cause and MM-specific early mortality (death within 6 months after the diagnosis of MM) was conducted by multivariate analysis. Trends in early mortality were studied by joinpoint regression analysis. RESULTS: Of the 90,975 MM cases included in this analysis, early mortality was noted in 21%. Median age was 68 years overall, and 75 years for the early mortality cohort (P < .01). The most common causes of death for early mortality were MM itself, followed by cardiovascular, infections, and renal failure. Male gender, "other" race/ethnicity group, advancing age, and West, Midwest or South regions (reference Northeast) were associated with increased risk of both all-cause and MM-specific early mortality. Joinpoint regression analysis of trends data resulted in 1 joinpoint for all-cause 6-month mortality (2006-2015), while 2 joinpoints were noticed for myeloma-specific 6-month mortality (1975-1987 and 2003-2015). CONCLUSION: Early mortality remains a significant unmet need for MM patient care, despite improving trends in recent years. Understanding the factors associated with early mortality can help develop individualized plans of patient care and mitigate circumstances that may contribute to early mortality among MM patients.

BACKGROUND: Factors associated with receiving initial care for thyroid cancer (TC) at academic centers (ACs) versus nonacademic centers (NACs) and their impact on patient outcomes have not been reported. METHODS: The National Cancer Database with TC cases from 2004 to 2013 was evaluated for association of type of center for initial care with socioeconomic factors and disease and treatment characteristics, as well as overall survival (OS; all-cause mortality). RESULTS: The patients with TC (n = 200,824) included were predominantly women (74%), non-Hispanic Whites (85%), and from metro areas (84%). Sixty percent received initial care at a NAC. There were no significant differences between treatment groups by age or gender. Among those treated at an AC, a higher proportion belonged to racial/ethnic minorities (16.5%) versus at a NAC (11.6%). Hormone therapy was used more in an AC versus a NAC (60% vs 47%). Patients with all TC pathologies combined had a lower likelihood of death when they received initial care at an AC (hazard ratio [HR], 0.948; P = .0006). Among individual pathologic subtypes, a lower likelihood of death was noted when initial care was received at an AC for follicular (HR, 0.828, P = .0010) and Hurthle cell cancers (HR, 792; P = .0008), as well as stage II papillary thyroid cancer (HR, 0.828; P = .0026), but not for other histopathologic subtypes. CONCLUSIONS: Initial care at an AC was associated with lower likelihood of death for patients with TC, especially for those with follicular or Hurthle cell subtypes. Optimal resource use with consideration of patients' socioeconomic and demographic factors is imperative to ensure the most appropriate management of patients with TC in various treatment settings.

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.

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.

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.

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.
