Serum phosphorus levels as a predictor and severity marker for mechanical ventilation in adults versus elderly patients – A cross-sectional study
Authors: Ambali Anand P , Tomar Priyanka , Shivanand L K 
Published: August 2024

Objectives
Mechanical ventilation (MV) is a supportive therapy for patients with acute respiratory failure. Studies have shown direct relationship between serum phosphorus on admission and risk of respiratory failure requiring MV. This study aims to determine admission serum phosphorus level’s ability to predict severity in 64 mechanically ventilated patients among two groups: Group A was designated to adults (<60 years of age) and Group B to elderly (60 years or older) admitted to the critical care unit (CCU). Study Design: It is a cross-sectional study.

Material and Methods
Data were collected from 64 adults admitted to CCU. The Sequential Organ Failure Assessment (SOFA) score and serum Phosphorus level on admission were assessed. Patients with Diabetic Ketoacidosis, Head Trauma, Renal Failure, Hyper or Hypoparathyroidism, Leukaemia, and Lymphoma were excluded.

Results
The study had 32 subjects in each group. The commonest indication for mechanical ventilation was Poisoning (31.25%) in Group A and Cerebrovascular Accident (34.37%) in Group B. The common complication among the study group was ventilator- associated pneumonia (14.06%). Out of 64 patients requiring mechanical ventilation, nine patients had hypophosphatemia, and eighteen had hyperphosphatemia. In the case of hypophosphatemia, 100% and in hyperphosphatemia, 55.5% mortality was observed.

Conclusion
Altered serum phosphorus levels on admission can be a potential indicator for requiring MV and mortality. Both hypophosphatemia and hyperphosphatemia are potential risk factors for the development of respiratory failure. Also, age-related variation in phosphorus levels has not shown any association with the outcome.

The objective of this study was to compare the clinical response of patients with chronic plaque psoriasis treated with MTX versus APM.

Materials and Methods:
This is a 1½ year descriptive observational study of all new chronic plaque psoriasis patients. The sample size was 64 (31 in MTX group and 33 in APM group). Sixty-four patients diagnosed with chronic plaque psoriasis were treated with MTX or APM. The patients were evaluated for therapeutic outcome by psoriasis area and severity index (PASI) score at 4 weeks, 12 weeks, and 24 weeks. The efficacy of drugs was compared using PASI 75. The data obtained from the patient was entered in Microsoft Excel and analyzed using the Statistical Package for the Social Sciences software.

Results:
Out of the 64 patients, 31 were treated with MTX and 33 patients were treated with APM. At 12 weeks, 35.5% of patients receiving MTX group achieved PASI 75 whereas only 9% of patients achieved PASI 75 in APM group which was found to be statistically significant (P = 0.01). The PASI 75 was achieved by 93.5% of patients in the MTX group and 87.9% of patients in the APM group with no statistical significance at 24 weeks.

Conclusion:
The MTX and APM demonstrated equal efficacy in the treatment of chronic plaque psoriasis at the end of 24 weeks.

Published: August 2024

This study addresses the issue of controlling the inventory of raw materials for pen production at PT. XYZ uses Material Requirement Planning (MRP) to minimize excess inventory. The MRP calculates net requirements, planned receipts, planned order releases, and projected on-hand inventory based on estimated demand, product structure, lot size, lead time, and safety stock. The results categorize 20 raw material components for ballpoint pen products into five levels, determining the optimal quantity and timing for ordering and receiving each component to meet production plans while avoiding excess stock or shortages. This study concludes that the MRP method can significantly optimize inventory management, reducing the risks of overstock and stockouts in the pen production process at PT. XYZ. Consistent application of the MRP method and regular evaluation of supplier capabilities are recommended to ensure efficient and effective raw material inventory planning and control.
