Background: COVID-19 has been associated with a higher risk of death in patients with diabetes mellitus (DM). However, there is a dearth of data regarding the effects of diabetic ketoacidosis (DKA) in these patients. We explored the in-hospital outcomes of patients who presented with COVID-19 and DKA. Methods: A propensity score-matched observation...
Article
Background COVID-19 has been frequently associated with an increased risk of thrombotic complications. There have also been reports of an increased likelihood of stroke, although its true incidence in patients with COVID-19 is currently unknown. Methods Electronic databases PubMed and Scopus were searched from inception up to July 30, 2021 to iden...

While the relative efficacy of remdesivir as a therapeutic agent in selected patients with COVID-19 has been established, safety concerns have been raised regarding potential nephrotoxicity and hepatotoxicity. Our main objective was to investigate the kidney- and liver-related safety outcomes in patients with COVID-19 treated with remdesivir in a p...

This paper studies the impact of the 1st COVID-19 lockdown in Greece on the internet banking. Our study relies on a survey conducted, during the first lockdown period between April 13th and May 3rd, 2020 in Greece, among respondents between 18 and 64-years-old. The sample was appropriately weighted with the raking method to accurately reflect the d...

As is known, HOXB9 is an important factor affecting disease progression and overall survival (OS) in cancer. However, its role in colorectal cancer (CRC) remains unclear. We aimed to explore the role of HOXB9 in CRC progression and its association with OS in colorectal liver metastases (CRLM). We analysed differential HOXB9 expression in CRC using...

Severe obesity increases the risk for negative outcomes in patients with coronavirus disease 2019 (COVID-19). Our objectives were to investigate the effect of BMI on in-hospital outcomes in our New York City Health and Hospitals’ ethnically diverse population, further explore this effect by age, sex, race/ethnicity, and timing of admission, and, gi...
Article
The use of drug-coated devices (DCD) in peripheral arterial disease (PAD) intervention continues to remain controversial after a recent meta-analysis raised concerns of higher late mortality outcome with the use of these devices. Given this, there is need for more data with regards to the late mortality outcome with DCD use. We sought to assess the...
Article
Full-text available
It has been demonstrated that obesity is an independent risk factor for worse outcomes in patients with COVID-19. Our objectives were to investigate which classes of obesity are associated with higher in-hospital mortality and to assess the association between obesity and systemic inflammation. This was a retrospective study which included consecut...
Article

Together, chronic obstructive pulmonary disease (COPD) and asthma account for the most common non-infectious respiratory pathologies. Conflicting preliminary studies have shown varied effect for COPD and asthma as prognostic factors for mortality in coronavirus disease 2019 (COVID-19). The aim of this study was to explore the association of COPD an...

Background Previous studies unveiled a relation between the severity of COVID‐19 pneumonia and obesity. The aims of this multicenter retrospective cohort study were to disentangle the association of BMI and associated metabolic risk factors (diabetes, hypertension, hyperlipidemia, current smoking) in critically ill patients with COVID‐19. Methods...
Article
Objective To explore the possible associations of serum 25-hydroxyvitamin D concentration [25(OH)D] with COVID-19 in-hospital mortality and need for invasive mechanical ventilation. Patients and Methods A retrospective, observational, cohort study was conducted at two tertiary academic medical centers in Boston and New York. Eligible participants...

Background Diabetes Mellitus is one of the leading causes of morbidity and mortality in the world. Infectious diseases are more common and associated with worse outcomes among diabetics. Diabetes is considered a predictor of morbidity in patients with COVID-19. Methods Medline, Embase, Google Scholar, and medRxiv were systematically reviewed up to...
Article

Purpose: Infectious diseases are more frequent and can be associated with worse outcomes in patients with diabetes. The aim of this study was to systematically review and conduct a meta-analysis of the available observational studies reporting the effect of diabetes on mortality among hospitalized patients with COVID-19. Methods: The Medline, Embas...

Background: Infectious diseases are more frequent and can be associated with worse outcomes in patients with diabetes. Our aim was to systematically review and synthesize with a meta-analysis the available observational studies reporting the effect of diabetes in mortality among hospitalized patients with COVID-19. Methods: Medline, Embase, Google...
Article
Mobilization of valuable resources, especially of talented individuals, figures prominently in firms’ strategies and policy agendas. Thus far, there is a dearth of empirical evidence in the field. The contribution of this paper is two-pronged: first, to perform an integral evaluation of the different factors that shape the mobility of patent invent...
Article
Background Surveys report low frequencies of sexual history (SH) obtained in primary care. Sexually transmitted infections incidence can be reduced with timely screening. It is important to determine whether providers obtain thorough SH and to identify needs for improvement. Aim To evaluate the frequency and depth of SH taking in primary care. Me...

Background & Aims: New York is the current epicenter of Coronavirus disease 2019 (COVID-19) pandemic. The underrepresented minorities, where the prevalence of obesity is higher, appear to be affected disproportionately. Our objectives were to assess the characteristics and early outcomes of patients hospitalized with COVID-19 in the Bronx and inves...

Article
This paper exploits a particular facet of the US patent system, which thus far has been overlooked in the literature: the patent renewal fee scheme relating to switches from small to large entity status. Based on this observation, we are able to determine whether university patents are licensed over their enforceable lifecycle and at what point in...
Article
This paper examines the propensity for patents by individual inventors to be commercialized. By exploiting a peculiarity of the US patent system, concerning the different patent renewal fees paid in order to obtain small or large entity status, we are able to distinguish patents that become part of a large corporation’s patent portfolio. Using an e...
