During the pandemic, it has been recommended that vaccination against COVID-19 be a priority for patients with cancer; however, these patients were not included in the initial studies evaluating the available vaccines. To define the impact of vaccination against COVID-19 in preventing the risk of complications associated with the infection in a cohort of patients with cancer in Colombia. An analytical observational cohort study, based on national registry of patients with cancer and COVID 19 infection ACHOC-C19, was done.

This study investigated the utility of comprehensive genomic profiling (CGP), a hybrid capture-based next-generation sequencing (NGS) assay, in clinical practice in a developing country.
Methods: In this retrospective cohort study, CGP was performed on clinical samples from patients with different solid tumors recruited between December 2016 and November 2020, using hybrid capture-based genomic profiling, at the individual treating physicians' request in the clinical care for therapy decisions.
The absence of markers for diagnosis of idiopathic Parkinson's disease (IPD), multiple system atrophy (MSA), and progressive supranuclear palsy (PSP) results in these disorders being commonly mistaken for each other, particularly in the initial stages. We aimed to investigate annualized whole-brain atrophy rates (a-WBAR) in these disorders to aid in the diagnosis between IPD vs. PSP and MSA.

Such mistakes occur particularly in the initial stages, when "plus syndrome" has not yet clinically emerged.
Objective: To investigate the global brain volume and tissue loss in patients with PSP relative to patients with IPD and healthy controls and correlations between clinical parameters and magnetic resonance imaging (MRI)-derived brain volume estimates.
A 45 year old male presented with IgA multiple myeloma s/p (status post) autologous hematopoietic stem cell transplantation; and with a history of six weeks of fever and constitutional symptoms. Liver tests showed an infiltrative pattern, with ultrasound evidence of multiple nodular lesions. A laparoscopic biopsy identified circumscribed myeloma foci.

Myeloid-derived suppressor cells (MDSC; immunosuppressive myeloid cells including monocytes) have been identified in other cancers and correlate with tumor burden. We hypothesized that glioblastoma exposure causes normal monocytes to assume an MDSC-like phenotype and that MDSC are increased in glioblastoma patients.

The clinical manifestations range from severe neonatal lactic acidosis to chronic neurodegeneration. Optic neuropathy is an uncommon clinical sequela and the imaging findings of optic neuropathy in these patients have not previously been described.

Hearing loss is a frequent finding in CCD. We describe the CT craniofacial findings in CCD and provide a comprehensive discussion of the CT temporal bone findings in these patients.

Although levels of low-density lipoprotein cholesterol are often normal or only slightly elevated in persons with diabetes, lipid-altering therapy with statins has been shown in large, randomized, controlled trials to decrease the risk of cardiovascular complications in this patient population. A target low-density lipoprotein cholesterol level of <70 mg/dL is now a therapeutic option in patients at very high risk for coronary heart disease, including patients with diabetes.
