Concerns have been raised that patients with Coronavirus Disease 2019 (COVID-19) are still infectious with a re-positive nucleic acid test of the pharyngeal swab after hospital discharge. The aim of this study was to investigate the clinical relevance of induced sputum as an additional indicator for the current clinical discharge criteria of COVID-19 patients to prevent virus recurrence.

Twenty-one COVID-19 patients who met the national clinical discharge criteria were discharged from the hospital and tested daily for the presence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) nucleic acid in their pharyngeal swabs and every other day for the presence of SARS-CoV-2 in their induced sputum. Once the patient's induced sputum was negative after two consecutive tests, testing was discontinued.

Among 21 discharged patients from COVID-19, the first pharyngeal swab and induced sputum tests for viral nucleic acid were positive in 3 (14.3%) and 8 (38.1%) patients respectively. Induced sputum wasCOVID-19.
Hematologic cancer patients with Coronavirus Disease 2019 (COVID-19) tend to have a more serious disease course than observed in the general population. Herein, we comprehensively reviewed existing literature and analyzed clinical characteristics and mortality of patients with hematologic malignancies and COVID-19.

Through searching PubMed until June 03, 2020, we identified 16 relevant case studies (33 cases) from a total of 45 studies that have reported on patients with COVID-19 and hematologic malignancies. We investigated the clinical and laboratory characteristics including type of hematologic malignancies, initial symptoms, laboratory findings, and clinical outcomes. Then, we compared those characteristics and outcomes of patients with hematologic malignancies and COVID-19 to the general population infected with COVID-19.

The median age was 66-year-old. Chronic lymphocytic leukemia was the most common type of hematologic malignancy (39.4%). Fever was the most common symptom (75.9%). Most patients h-19 is rare. Raptinal cost However, due to the high mortality rate from COVID-19 in this vulnerable population, further investigation on tailored treatment and management is required.
The pandemic from SARS-CoV-2 is having a profound impact on daily life of a large part of world population. Italy was the first Western country to impose a general lockdown to its citizens. Implications of these measures on several aspects of public health remain unknown. The aim of this study was to investigate the effects of the lockdown on surgical emergencies volumes and care in a large, tertiary referral center.

Electronic medical records of all patients visited in our Emergency Department (ED) and admitted in a surgical ward from February 21st 2020 to May 3rd 2020 were collected, analyzed and compared with the same periods of 2019 and 2018 and a cross-sectional study was performed.

Number of surgical admissions dropped significantly in 2020 with respect to the same periods of 2019 and 2018, by almost 50%. The percentage distribution of admissions in different surgical wards did not change over the three years. Time from triage to operating room significantly reduced in 2020 respect to 2019 and 2018 (p<0.001).

The lockdown in Italy due to SARS-CoV-2 pandemic arguably represents the largest social experiment in modern times. Data provided by our study provide useful information to health authorities and policymakers about the effects of activity restriction on surgical accesses and changing epidemiology due to an exceptional external event.

Herein we report clinical and virological data in a patient with COVID-19 infection and a prior history of kidney transplantation who had a good clinical recovery despite systemic infection.

Reverse transcriptase quantitative PCR analysis for the RdRp, N and E target genes detected viral RNA in different types of biological specimens. Whole viral genome sequences were obtained and analyzed from respiratory tract, feces and blood.

Viral sequences showed high (~99.9%) homology with the Wuhan seafood market pneumonia virus. Phylogenetic analysis assigned of the SARS-CoV-2 strains to clade G. A rare variant in the orf1ab gene was present in both sequences, while a missense variant was detected only in viral RNA from stool.

The evolution of the COVID-19 systemic infection in the patient presented here was favorable to the hypothesis that immunosuppressive therapy in organ transplant recipients might be involved in viral dissemination. A missense mutation was present in only one specimen from the same patient implying the occurrence of a mutational event in viral RNA, which is suggestive for the presence of an active virus, even though viral isolation is necessary to demonstrate infectivity.

Caffeine is one of the most commonly used stimulants among pregnant women. Human and animal studies have shown that prenatal caffeine exposure affects fetal brain development and results in persistent cognitive deficits in offspring. Studies have found that caffeine consumption during pregnancy may alter many activities that are ultimately associated with cognitive dysfunction in offspring. Despite these important findings, there is a fundamental gap in understanding the mechanism underlying cognitive impairment due to prenatal caffeine exposure. Filling this knowledge gap would provide further insights into caffeine-mediated cognitive dysfunction. The objective of this review was to evaluate the findings of studies showing that prenatal caffeine exposure induces cognitive dysfunction and the potential underlying mechanisms.
