Nosocomial infections pose an imminent challenge to hospitalized Coronavirus disease-19 (COVID-19) patients due to complex interplay of dysregulated immune response combined with immunomodulator therapy. In the pre-pandemic era, immunomodulatory therapy has shown benefit in certain autoimmune conditions with untamed inflammatory response. Efforts to recapitulate these immunomodulatory effects in COVID-19 patients has gained impetus and were followed by NIH COVID-19 expert panel recommendations.

Article Synopsis
  • A new palladium catalytic system (PdAc-5) effectively oxidizes primary and secondary alcohols to aldehydes and ketones using oxygen at moderate pressures.
  • The catalyst's performance was evaluated using various analytical techniques and demonstrated high yields (70-85%) with cost-effective, non-toxic solvents and additives.
  • Comprehensive studies compared PdAc-5 against commercial catalysts and explored different conditions, ensuring the synthetic process of alcohol oxidation was reliable and thoroughly analyzed through advanced methods like H NMR and GC-mass.

Patients with heart failure (HF) may be at a higher risk of coronavirus disease 2019 (COVID-19) infection and may have a worse outcome due to their comorbid conditions and advanced age. In this narrative review, we aim to study the interaction between COVID-19 and HF from a critical care perspective. We performed a systematic search for studies that reported HF and critical care-related outcomes in COVID-19 patients in the PubMed and Medline databases.

Immune-mediated oral disorders are characterised by their chronicity, and some are refractory to treatment. Interference RNA (iRNA) has been implicated in the underlying mechanism of such immune-mediate oral and refractory inflammatory oral diseases. iRNA-based understanding of the mechanism in these diseases may help to produce non-invasive diagnostic methodologies and treatment modalities of such drug non-responsive diseases.

Oral physicians frequently encounter medically compromised patients in their everyday practice and a sizable number of these patients are in urgent need of specialized care. One such medically specialized category is that of patients suffering from hydrocephalus. A large number of medical reports and citations in support of surgical care of the hydrocephalic disorder are available in literature.
