Topical Sodium Nitrate Ointment for Sickle Cell Disease

Chronic leg ulcers are a debilitating vasculopathic complication for some patients with sickle cell disease (SCD). Prevalence of leg ulcers varies based on age and geographic location; about 5-10% of all SCD patients may suffer leg ulcers. These leg ulcers are painful, result in infections, hospitalization, disability, and negatively impact the patient ’s social and psychological wellbeing on an ongoing basis. Until recently, patients with SCD only had one drug treatment option: hydroxyurea, which was approved by the Food and Drug Administration (FDA) in 1998 in adults and in 2017, in children age 2 and older.  However, there are no FDA-approved treatments specifically to treat SCD ulcers. The ulcer may take months or even years to heal. Opioid drugs are often administered to relieve intense pain symptoms, but the opioids do not treat the underlying wound conditions and carry addiction risks with chronic use. Thus, there is an unmet medical need to develop therapies that heal SCD ulcers.   Scientists at the National Institutes of Health (NIH) have developed a novel medical formulation; a promising sodium-nitrite cream for treating leg ulcers in SCD patients. The topical ointment helps increase nitric oxide levels in the wound. The specific formulation allows nitric oxide gas to dilate vessels by relaxing their smooth muscle cells. This aids healing the wound by increasing the amount of oxygenated blood that reaches the ulcer. A completed Phase 1 clinical tri...

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Currently in fellowship doing bread/butter procedures (MBB, epidurals, PNB, few SCS/PNS trials, etc.) and just interviewed at a private practice spot where they do a lot of procedures that I will have not done any training in prior to graduating (e.g. IT pump, SI fusion, Vertiflex, Kypho, MILD, Discectomy, lots of SCS/PNS trials etc) and significant amount of "OR pain procedures" at a very busy practice seeing 30-40 pts/day - how many of you are commonly performing these procedures and are... private practice concern

Authors: Matti B, Zargar-Shoshtari K Abstract Prostate cancer represents a significant health burden worldwide. The cancer incidence had substantially increased since the introduction of prostate specific antigen (PSA) in cancer screening. This had led to considerable debates among health professionals and epidemiologists, since PSA as a screening tool seemed to be far from perfect. In New Zealand, the controversy was quite prominent in the last three decades, with some advocating the benefits of screening, while others concerned regarding the risk of harms. With the absence of an organised screening programme and ...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.
