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.

We have reported an aerobic oxidation of primary and secondary alcohols to respective aldehydes and ketones using a bipyridyl-cinchona alkaloid based palladium catalytic system (PdAc-5) using oxygen at moderate pressure. The PdAc-5 catalyst was analysed using SEM, EDAX, and XPS analysis. The above catalytic system is used in experiments for different oxidation systems which include different solvents, additives, and bases which are cheap, robust, non-toxic, and commercially available on the industrial bench.

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.
