Background: The resuscitation guidelines indicate pre-arrival dispatcher-assisted telephone CPR (DATCPR) instructions and measurement to increase the proportion of bystander CPR (BCPR), however the impact of those guidelines on survival is not well known. Objective: To describe the impact of a comprehensive bundle of DATCPR on BCPR and survival from OHCA in a horizontal computerized-aided dispatch (CAD) system. Methods: A centralize CAD system in a metropolitan EMS is studied. Routinely in system the time from call to ambulance dispatch should be within 60 seconds. The audio recordings of confirmed OHCAs were reviewed using a standardized format linked with EMS and hospital process and outcome data. The proportions of BCPR and survival six months after implementation (P1) of a bundle that included guideline-based protocol changes, staff training, computerized audit, feedback to providers and leadership rebuilt are compared with that of the same month period in the prior year as control group (P0), using regression analysis for statistics. Results: There were 1437 OHCAs [665 P0, 772 P1; 64% male, median age 62 (IQR: 47-74)](Table 1). The rate of BCPR went from 20.6% in P0 to 35.0% in P1 (p<0.001). Outcome of ROSC (return to spontaneous circulation) upon hospital arrival was significantly higher in P1 (10.4%) compared to P0 (6.6% p=0.037), as was good neurological outcome (CPC 1or2: 5.5% in P1 vs. 2.6% in P0 p=0.029). Survival to hospital discharge was higher in P1 (8.3%, vs. P0: 6.4%) but not statistically significant. After adjusting for witnessed arrest, shockable rhythms, age, sex, and pre-hospital time intervals, good neurological outcome were still significantly higher in P1 vs. P0 [adjusted odds ratios: 2.1 (95% 1.1-4.4)]. Conclusions: The implementation of a comprehensive bundle of DATCPR in a metropolitan horizontal dispatch system was associated with significant improvements in the rates of BCPR and good neurologic outcome after OHCA.

During the Covid Pandemic, a lot of structural and process changes had to be made in a quick time in almost all the hospitals to accommodate the patients and admit them with the least exposure to the Hospital Staff and the bystanders of the patients. AIIMS Hospital in New Delhi India is a premier tertiary care teaching hospital, which is spread out in different areas. Two Hospital centers of AIIMS were designated as COVID Hospitals. Since there was no previous experience of intrahospital transfers of this magnitude, the hospital had to face lots of difficulties in such transfers and this translated into increased turnaround time. This paper concentrates on the mechanisms in which the Department of Hospital Administration found out the various issues plaguing this process. Later by Change Management, an Intervention was brought in, which helped in the framing of a standard operating procedure that helped in the easy transfer of the patients which was hassle-free and which continued to the second wave of the COVID pandemic.

AbstractIntroduction:In Australia, cardiac arrest kills 142 out of every 100,000 people each year; with only 3–4% of out-of-hospital patients with cardiac arrest in Melbourne surviving to hospital discharge. Prompt initiation of cardiopulmonary resuscitation (CPR), defibrillation, and advanced cardiac care greatly improves the chances of survival from cardiac arrest. A critical step in survival is identifying by the emergency ambulance dispatcher potential of the probability that the person is in cardiac arrest. The Melbourne Metropolitan Ambulance Service (MAS) uses the computerized call-taking system, Medical Priority Dispatch System (MPDS), to triage incoming, emergency, requests for ambulance responses. The MPDS is used in many emergency medical systems around the world, however, there is little published evidence of the system's efficacy.Objective:This study attempts to undertake a sensitivity/specificity analysis to determine the ability of MPDS to detect cardiac arrest.Methods:Emergency ambulance dispatch records of all cases identified as suspected cardiac arrest by MPDS were matched with ambulance, patient-care records and records from the Victorian Ambulance Cardiac Arrest Registry to determine the number of correctly identified cardiac arrests. Additionally, cases that had cardiac arrests, but were not identified correctly at the point of call-taking, were examined. All data were collected retrospectively for a three-month period (01 January through 31 March 2003).Results:The sensitivity of MPDS in detecting cardiac arrest was 76.7% (95% confidence interval (CI): 73.6%–79.8%) and specificity was 99.2% (95% CI: 99.1–99.3%). These results indicate that cardiac arrests are correctly identified in 76.7% of cases.Conclusion:Although the system correctly identified 76.7% of cardiac arrest cases, the number of false negatives suggests that there is room for improvement in recognition by MPDS to maximize chances for survival in out-of-hospital cardiac arrest. This study provides an objective and comprehensive measurement of the accuracy of MPDS cardiac-arrest detection in Melbourne, as well as providing a baseline for comparison with subsequent changes to the MPDS.

Structurally-oriented biologists examine cells, tissues, organelles and macromolecules in order to gain insight into cellular and molecular physiology by relating structure to function. The understanding of these structures can be greatly enhanced by the use of techniques for the visualization and quantitative analysis of three-dimensional structure. Three projects from current research activities will be presented in order to illustrate both the present capabilities of computer aided techniques as well as their limitations and future possibilities.The first project concerns the three-dimensional reconstruction of the neuritic plaques found in the brains of patients with Alzheimer's disease. We have developed a software package “Synu” for investigation of 3D data sets which has been used in conjunction with laser confocal light microscopy to study the structure of the neuritic plaque. Tissue sections of autopsy samples from patients with Alzheimer's disease were double-labeled for tau, a cytoskeletal marker for abnormal neurites, and synaptophysin, a marker of presynaptic terminals.

The microtubule (MT) cytoskeleton is necessary for many of the polarized functions of hepatocytes. Among the functions dependent on the MT-based cytoskeleton are polarized secretion of proteins, delivery of endocytosed material to lysosomes, and transcytosis of integral plasma membrane (PM) proteins. Although microtubules have been shown to be crucial to the establishment and maintenance of functional and structural polarization in the hepatocyte, little is known about the architecture of the hepatocyte MT cytoskeleton in vivo, particularly with regard to its relationship to PM domains and membranous organelles. Using an in situ extraction technique that preserves both microtubules and cellular membranes, we have developed a protocol for immunofluorescent co-localization of cytoskeletal elements and integral membrane proteins within 20 µm cryosections of fixed rat liver. Computer-aided 3D reconstruction of multi-spectral confocal microscope images was used to visualize the spatial relationships among the MT cytoskeleton, PM domains and intracellular organelles.
