Doxofylline is a xanthine derivative and it has its application as a bronchodilator in different pulmonary conditions like asthma and COPD (chronic obstructive pulmonary disease). The research was conducted with the objective to develop and validate a simple, easy, rapid and cost-effective UV-Spectrophotometric method to estimate the amount of doxofylline in bulk and tablets. The validating parameters and methodology were selected and performed according to ICH and USP guidelines. In the accuracy study, the mean % recovery was within the limit (100.20%) with %RSD 0.77. The mean of % assay and %RSD of intra-assay precision study was found 99.81 and 0.79 respectively with only 0.57% variation between two analysts in intermediate precision study. The linearity study demonstrated the value of the correlation coefficient is 0.9999 whereas the robustness studies showed a slight but negligible variation of absorbance while changing different operating parameters. In system suitability study, the %RSD was found less than 2.00%. According to the specificity study, there were no placebo and diluent effect on the absorbance measurements.

Abstract Funding Acknowledgements Type of funding sources: None. Objectives Mechanical ventilation is the short-term technical support most widely used and cardiac arrest its main indication in a Coronary Care Unit (CCU). However, the knowledge about the specific moment and ventilator mode of onset to avoid the acute lung injury is still equivocal. Our objective is to determine the survival rate and the prognostic factors in patients supported by mechanical ventilation. Methods We conducted a retrospective cohort study of adult patients admitted to the CCU between January 2018 and November 2020 that received mechanical ventilation during the hospital stay. Results We collected 94 patients, 28% females with a median age of 68 ± 11,9. 43% were diabetics and almost one quarter of them had some degree of chronic obstructive pulmonary disease (COPD). Ischemic cardiopathy (33%) and heart failure (31%) were frequent pathologies as well as renal injury (29% patients a filtration rate below 45 mL/min/1,73m2). The reason for initiating mechanical ventilation was cardiac arrest in the half of the patients. Volume-controlled ventilation (73%) was the initial setting mode in most cases. The support with vasoactive drugs were highly necessary in these patients (Infection rate of 48%). In the subgroup analysis, we realized that the number of reintubations and the necessity of non-invasive ventilation were higher in the COPD group (p = 0,01), as well as tracheostomy (p = 0,03). COPD patients also needed higher maintaining PEEP, though this was not statistically significant. The mean length of stay in the intensive care unit of our cohort was 11 days (range: 1-78 days; median: 8 days) and the mean length of mechanical ventilation 6 days (range: 1-64 days; median: 3 days). The in-hospital mortality was 41,4%. Conclusions Cardiac arrest is the most common reason of mechanical ventilation support. Our study showed that COPD patients presented more complications during the weaning and the period after extubation. In-hospital mortality remains high in intubated patients.

Objective: To determine the outcome of early use of non-invasive positive pressure ventilation (NIPPV) in Pakistani patients with acute exacerbation of chronic obstructive pulmonary disease. Methods: This descriptive study was conducted at Shifa International Hospital Islamabad from April 2015 to January 2017. A total of 120 patients with acute exacerbation of chronic obstructive pulmonary disease receiving NIPPV alongside standard therapy were included in the study. The patients were clinically assessed before starting on NIPPV. The parameters of respiratory rate, pH and paCO2 were monitored and NIPPV was given for six hours to evaluate clinical outcomes and analyze the factors predicting failure (requirement of mechanical ventilation and mortality). Frequency and percentages were calculated for qualitative variables while Mean and Standard Deviation for quantitative variables. Chi-square and t-test were used to see differences in pre and post NIPPV arterial blood gases. Results: Patients’ mean age was 58.88±10.09 years. Males were 88 (73.3%) and females were 32 (26.7%). The mean respiratory rate was 24±1.45 per minute before and 17.96±1.35 per minute after NIPPV (p < 0.00001). The mean pH before NIPPV was 7.27±0.04 and afterwards 7.38±0.02 (p < 0.00001). The mean pCO2 was 61.87±9.60 mm of Hg before and 57.46±6.79 mm of Hg after NIPPV (P < 0.0003). Twenty Four (20%) patients required invasive ventilation of which 19 (15.8%) patients could not survive. Conclusions: There was remarkable improvement in the arterial blood gases after NIPPV. However, the high mortality rate and significant number of COPD patients requiring mechanical ventilation necessitates further investigation into our population. doi: https://doi.org/10.12669/pjms.35.6.857 How to cite this:Ishfaq N, Gul N, Zaka N.

Objectives: Asthma and chronic obstructive pulmonary disease (COPD) are chronic illnesses of the airways affecting a good number of people in Lebanon and the Middle East. Pressurized metered-dose inhalers (pMDIs) are important drug delivery systems used to treat such pulmonary diseases. Drugs proven to be valuable and effective may fail to act effectively if such inhalers are used incorrectly. The purpose of this study was to assess the technical use of pMDIs by patients with pulmonary diseases presenting to the community pharmacies in Lebanon. Methods: A structured questionnaire was developed to collect data. A total of 601 patients using drugs delivered through pMDIs and presenting to 12 Lebanese community pharmacies were recruited to participate in the research project. The questionnaire items were divided into 3 subscales: subscale 1—assessing the device preparation; subscale 2—investigating the device use; and subscale 3—examining the knowledge and use of spacers. After confirming the reliability and validity of the survey tool, patients’ responses were analyzed and compared according to many variables. Results: Many patients answered inaccurately to questions assessing both the device preparation and use. Around 40% of patients said they do not coordinate the inhalation with pressing the canister down. The mean scores were 1.72 (± 0.73) over 6 and 5.67 (± 1.44) over 7 for subscales 1 and 2, respectively. The mean total score on all questions was 7.39 over 13, with a standard deviation of 1.75. While patients’ age did not impact the results, asthmatic, well-educated, male patients had fewer wrong answers when it comes to preparing and using the device ( P < .01). Conclusions: Our study showed that many patients with asthma and COPD might not be properly using their pMDIs. Appropriate inhaler use is crucial for successful pulmonary disease management. As pMDIs are one of the most difficult devices to use, proper and tailored instructions should be given to patients.

Using Data

In this work, a mobile application is developed to assist patients suffering from chronic obstructive pulmonary disease (COPD) or Asthma that will reduce the dependency on hospital and clinic based tests and enable users to better manage their disease through increased self-involvement. Due to the pervasiveness of smartphones, it is proposed to make use of their built-in sensors and ever increasing computational capabilities to provide patients with a mobile-based spirometer capable of diagnosing COPD or asthma in a reliable and cost effective manner. Data collected using an experimental setup consisting of an airflow source, an anemometer, and a smartphone is used to develop a mathematical model that relates exhalation frequency to air flow rate. This model allows for the computation of two key parameters known as forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) that are used in the diagnosis of respiratory diseases. The developed platform has been validated using data collected from 25 subjects with various conditions. Results show that an excellent match is achieved between the FVC and FEV1 values computed using a clinical spirometer and those returned by the model embedded in the mobile application.

Some beverages and smoking cause an inflammatory response in the lungs and airways in a similar way, ultimately affecting chronic obstructive pulmonary disease (COPD) occurrence. Using a nationally representative health survey database, this study investigates the individual and joint effects of consumption of different beverages and smoking on COPD. This study is a cross-sectional analysis of 15,961 Korean adults in the Korea National Health and Nutritional Examination Survey of 2008–2015. COPD was defined as forced expiratory volume in 1 s (FEV1) divided by forced vital capacity (FVC) <0.70. We used multiple linear and logistic regression models to examine the association of beverage consumption and smoking with an FEV1/FVC ratio and odds ratio (OR) for COPD. The mean FEV1/FVC ratio decreased with increasing soda intake (p = 0.016), coffee intake (p = 0.031), and smoking status; however, the mean FEV1/FVC ratio increased with increasing green tea intake frequency (p = 0.029). When soda intake increased to 10 times/month, the OR of having COPD increased to 1.04 times (95% CI: 1.01, 1.07). The positive joint effect of soda intake and smoking on COPD was marginally significant (p = 0.058). We found that soda intake, coffee intake, and smoking increased airflow limitation while green tea intake decreased it. In addition, soda intake and smoking had a positive joint effect on COPD in the Korean population.

Introduction: More than 15 million adults in the USA have chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease (COPD) places a high burden on the healthcare system. Many hospital admissions are due to an exacerbation, which is suspected to be from a viral cause. The purpose of this analysis was to compare the outcomes of patients with a positive and negative respiratory virus panel who were admitted to the hospital with COPD exacerbations. Methods: This retrospective cohort study was conducted in the Geisinger Healthcare System. The dataset included 2729 patient encounters between 1 January 2006 and 30 November 2017. Hospital length of stay was calculated as the discrete number of calendar days a patient was in the hospital. Patient encounters with a positive and negative respiratory virus panel were compared using Pearson’s chi-square or Fisher’s exact test for categorical variables and Student’s t-test or Wilcoxon rank-sum tests for continuous variables. Results: There were 1626 patients with a total of 2729 chronic obstructive pulmonary disease exacerbation encounters. Nineteen percent of those encounters (n = 524) had a respiratory virus panel performed during their admission. Among these encounters, 161 (30.7%) had positive results, and 363 (69.3%) had negative results. For encounters with the respiratory virus panel, the mean age was 64.5, 59.5% were female, 98.9% were white, and the mean body mass index was 26.6. Those with a negative respiratory virus panel had a higher median white blood cell count (11.1 vs. 9.9, p = 0.0076). There were no other statistically significant differences in characteristics between the two groups. Respiratory virus panel positive patients had a statistically significant longer hospital length of stay. There were no significant differences with respect to being on mechanical ventilation or ventilation-free days. Conclusion: This study shows that a positive respiratory virus panel is associated with increased length of hospital stay. Early diagnosis of chronic obstructive pulmonary disease exacerbation patients with positive viral panel would help identify patients with a longer length of stay.

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is one of the leading causes of mortality and morbidity worldwide. Though COPD is mainly a chronic disease, many patients experience exacerbations that are related to worst survival outcome, especially with abnormal serum electrolyte level. The objective of this study was to evaluate serum electrolyte levels among the patients with acute exacerbation of COPD. Methods: Structured questionnaire and patients’ charts were used to collect data. Data was analyzed using Statistical Package for the Social Sciences (SPSS) software version 16.0 and descriptive statistics were used to generate the research findings. Results: The mean age of the patients with Acute exacerbation of COPD was 69.57± 9.765 years. Among 100 patients, (83%) belonged to the age group of 60 years and above, (54%) were male, (74%) were married, (52%) were illiterate and (41%) were engaged in agriculture, (41%) consumed alcohol and (67%) were smokers. Dyspnoea (90%) was the most common symptom. The mean level of sodium and potassium were 133.8±4.830 mEq/L, 3.6±0.533 mmol/L, respectively. Fifty seven percent patients had electrolyte disorder. More than half (51%) had hyponatremia and (40%) had hypokalemia. The average value of pH, PaCO2 and PaO2 are 7.34 ± 0.727, 46.64 ± 9.787 mm Hg and 69.38 ± 9.255 mm Hg respectively. Among them, (18%) were in respiratory failure. Conclusion: This study concluded that hyponatremia and hypokalemia are prevalent electrolyte disorder with AE of COPD patients. Therefore, we recommend routine monitoring of the serum electrolytes for better outcomes of patients.

Abstract A chromatofocusing column method for isolating ApoB is described. LDL is first isolated by sequential ultracentrifugation and delipidated with n-butanol/diisopropyl ether. Chromatofocusing of ApoLDL yielded a large ApoB peak at pI 5.0-5.3. ApoA-I and ApoC-II were prepared analogously, with HDL and VLDL as the source of apoprotein. Antisera were raised in rabbits, and electroimmunoassay techniques were used for determination. ApoB was water-soluble after chromatofocusing. Intra-assay precision (CV) was 4.7% for ApoA-I, 7.8% for ApoB in the "rocket" electrophoresis. Interassay precision (CV) was 6% for ApoA-I and 8% for ApoB. Apolipoprotein concentrations were measured in subjects who had undergone lung resection and patients with obstructive pulmonary disease. After lung resection, the concentration of ApoA-I in serum was significantly decreased (p less than 0.001) and that of ApoB significantly increased (p less than 0.001) as compared with controls. The ApoA-I/ApoB ratio was significantly lower in the lung-resection group. ApoA-I and ApoB concentrations were unchanged in chronic obstructive pulmonary disease. ApoC-II concentrations in each group were similar to those for control subjects. Of the lipids, values for total cholesterol were above normal after lung resection (p less than 0.002), as were those for triglycerides (p less than 0.02).
