    Opis:
    Hypernatremia is a frequent and potentially life-threatening condition in hospitalized patients. It is a disorder of water metabolism and is usually defined as a plasma sodium concentration above 145 mEq/L. The treatment of severe cases of hypernatremia might be challenging in patient with feeding jejunostomy. The average person’s GI tract secretes and reabsorbs around 7 L of gastrointestinal fluid (including 3-5 L originating above the pylorus alone). These 7 L of gastrointestinal fluid will significantly dilute whatever we consume or infuse. However, this dilution of enteral feed may be bypassed in by feeding jejunostomy. There are very few cases reported on extreme hypernatremia. We present a case of severe hypernatremia in patient with feeding-jejunostomy, managed successfully with the recommended correction.

    Opis:
    Chronic kidney disease (CKD) is characterized by loss of kidney function and generally it is associated with several alterations in pulmonary functions, including restriction, obstruction, and impaired diffusion capacity. It became challenging to maintain oxygenation in a CKD patient associated with COVID 19 on non-invasive ventilation (NIV). In patients with end stage renal disease (ESRD), several factors likes, fluid overload, anaemia, immune suppression, extraosseous calcification, malnutrition, electrolyte imbalance, and acid-base disorder affecting the lungs indirectly. Here we are reporting NIV failure in two COVID 19 patients during dialysis. Both patients were stable on NIV before starting dialysis and underwent oxygen desaturation and shifted to invasive mechanical ventilation during hemodialysis. The possible mechanism of the oxygen desaturation is alveolar hypoventilation in the absence of hypercapnia, which may be due to the removal of CO2 from the body by some route (dialysate) other than the lungs.

    Opis:
    INTRODUCTION: Elderly COVID-19 patients admitted to the intensive care unit (ICU) are at high risk of an inflammatory syndrome, hypercatabolic reaction, malnutrition, and physical immobilization. This may result in loss of muscle mass and pulmonary infection leading to prolonged ventilatory support. Factors responsible for muscle mass loss in ICU are (1) microcirculatory disturbances, (2) presence of systemic inflammatory response syndrome (SIRS), (3) sepsis (4) drugs (corticoids, neuromuscular blockers) having inhibitory activity on the nervous system, neuromuscular junction and muscle itself. Mechanism of muscle atrophy in critically ill elderly patients include an imbalance between protein synthesis and degradation. Interventions to manage muscle atrophy for the patients admitted to ICU is also extrapolated to mechanically ventilated COVID-ARDS patients. PURPOSE: Early recognition of factors contributing to intensive care unit acquired weakness (ICUAW) in COVID-19 patients, inflammation, high catabolic phase, steroid use, and paralysis. The potential interventions to target these specific mechanisms and ameliorate muscle dysfunction in COVID-19 patients. CONCLUSIONS:Intensive care unit acquired weakness (ICUAW) in critically ill COVID-19 patients is due to severity of illness, co-morbidities, muscle unloading, or ICU treatments, a systemic reaction circulating within the body, or combinations therein. Furthermore, the availability of a culture model of ICUAW could facilitate in expediting the diagnosis of ICUAW and fast track the discovery of putative treatments. We recommend NIV or HFNC ventilation or early weaning from invasive mechanical ventilation in critically ill COVID-19 elderly patients.

    Opis:
    The onset of stationary convection in thermal instability of porous layer saturating a Jeffrey nanofluid is studied. The behaviour of nanofluid is described by a Jeffrey fluid model and the porous layer is assumed to follow Darcy’s law. Due to the presence of the Jeffrey parameter and nanoparticles, the momentum-balance equation of fluid is modified. The linear stability analysis and normal modes analysis method are utilised to derive the dispersion relation for the Rayleigh number in terms of various parameters for free-free boundaries. The effects of the Jeffrey parameter, Lewis number, modified diffusivity ratio, nanoparticles’ Rayleigh number and medium porosity on the physical system are discussed analytically and graphically.
