Abstract Background Previous reports have documented seasonal variation in out-of-hospital cardiac arrest (OHCA), with peak incidence in winter months, regardless of geographical region. However, seasonal variation in in-hospital cardiac arrest (IHCA) has not been well studied. Purpose To assess seasonal variation in incidence of in-hospital cardiac arrest, as well as gender and mortality differences. Methods We queried the 2014 National Inpatient Service (NIS) database for the total numbers of inpatient hospitalizations and in-hospital cardiac arrests for each month, as identified by ICD-9 codes (99.60 and 99.63). The trend for each month was plotted to assess seasonal variations in hospitalizations, IHCA, and mortality. Seasonal Variations in IHCA Results The mean age of the study population was 57.3±0.2 years and 58.9% were female. Out of 29,717,872 total inpatient hospitalizations in 2014, the overall IHCA event for the year was 0.38%. Females were more likely to be hospitalized; however, males were more likely to have IHCA. These gender differences persisted throughout the year. Overall, more hospitalizations and IHCA were seen in the winter compared to the summer, and this trend was seen in both men and women. The highest incidence of in-hospital cardiac events occurred in January and the lowest incidence occurred in June. There was no seasonal variation in mortality in both male and female patients who suffered IHCA. Conclusion(s) In this observational study, seasonal variation is present in in-hospital cardiac arrest. Cardiac events are highest in the winter months as compared to the summer months; however, the mechanism of this variation is unknown and warrants further study. Acknowledgement/Funding None

Introduction: Heart Disease and Stroke Statistics_2014 Update suggests more than 424,000 people suffer out of hospital cardiac arrest (OHCA) in the United States. Hypothesis: We assessed seasonal variation in OHCA from a large national hospitalisation database in the past decade. Methods: The Nationwide Inpatient Sample database was used to estimate the annual number of hospitalisations with from 2000-2011. Identification of out of hospital cardiac arrest related hospitalisations was based on the designation of the International Classification of Diseases (9th Edition) Clinical Modification (ICD-9-CM) diagnosis code 427.5 (OHCA) as the principal discharge diagnosis. The frequency of hospitalisation for each month cumulative over 11 years was calculated and divided by number of days in that month to obtain the mean hospitalisations per day for each month. All calculations were carried out using the weighted estimates approximating nationwide population estimates. Results: An estimated 93,209 hospitalisations with primary diagnosis of OHCA occurred in the United States from the beginning of the calendar year 2000 to the end of the calendar year 2011. The number of hospitalisations per day in each month is shown in Figure 1.The number of hospitalisation was maximum in the winter months and minimum in summer months. Specifically, the mean number of hospitalisation each day (averaged over 11 years) was least in August (242). There was a rising trend from August to January. The average number of hospitalisation was highest in January (310); thereafter, the hospitalisation rate dropped to a nadir in August. There was however no seasonal pattern in inhospital mortality. Conclusions: We identified for the first time in United States an impressive pattern of seasonal variation in hospitalisations for OHCA. Further efforts must be made to identify triggers and methods to prevent OHCA and reduce its burden on health care system.

Aim: To evaluate the priority of coronary angiography (CAG) and therapeutic hypothermia therapy (TH) after return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA). Patients and Methods: SOS-KANTO 2012 study is a prospective, multicenter (69 emergency hospitals) and observational study and includes 16,452 patients with OHCA. Among the cases with ROSC in that study, we intended for patients treated with both CAG and TH within 24 hours after arrival. Those patients were divided into two groups; patients in whom TH was firstly performed (TH group), and the others in whom CAG was firstly done (CAG group). We statistically compared the prognosis between the two groups. SPSS Statistics 22 (IBM, Tokyo, Japan) was used for the statistical analysis. Statistical significance was assumed to be present at a p value of less than 0.05. Result: 233 patients were applied in this study. There were 86 patients in the TH group (M/F: 74/12, mean age; 60.0±15.2 y/o) and 147 in the CAG group (M/F: 126/21, mean age: 63.4±11.1 y/o) respectively, and no significant differences were found in the mean age and M/F ratio between the two groups. The overall performance categories (OPC) one month after ROSC in the both groups were as follows; in the TH group, OPC1: 21 (24.4%), OPC2: 3 (3.5%), OPC3: 7 (8.1%), OPC4: 8 (9.3%), OPC5: 43 (50.0%), unknown: 4 (4.7%), and in the CAG group, OPC1: 38 (25.9%), OPC2: 13 (8.8%), OPC3: 15 (10.2%), OPC4: 18 (12.2%), OPC5: 57 (38.8%), unknown: 6 (4.1%). There were no significant differences in the prognosis one month after ROSC between the two groups. Conclusion: The results which of TH and CAG you give priority to over do not affect the prognosis in patients with OHCA.

Aims: To measure the waist circumference of Sudanese adults in Khartoum Locality and its relationship to blood pressure and lifestyle  during celebration of international day of hypertension in May 2016 . Study Design: It was a descriptive cross-sectional study. Place of the Celebration: Khartoum Locality at Alsahaa Alkhadraa (The Green Park). Methodology: A total of 364 adult participants, 196 men and 168 women were interviewed using structured questionnaire. Blood pressure (BP) was measured considering hypertension as ≥ 140 mmHg and ≥ 90 mmHg for systole and diastole BP respectively. Waist circumference was measured using an anthropometric measuring tape at cut-off point of 94 cm and 80 cm for men and women respectively. Data was managed by SPSS version 20 and Chi-square test at 95% CL was used to test the association between waist circumference, blood pressure and life style characteristics. Results: Age distribution of the study population showed 48.2% females and 45.4% males in the middle age group (38-57 years). Two thirds of the study population were hypertensive, 62.8% of males and 64.3% of females. The mean waist circumference of men was 97.82 cm + 16.7, mean Systolic BP was 127 + 22 and mean Diastolic BP was 85 + 15. The mean waist circumference of women was 99.31 + 16.2, mean Systolic was 128 + 24 and mean Diastolic BP was 84 +17. Abnormal waist circumference was found in 61.2% of males and 86.9% of females. Fifty nine (30.1%) of the males and 86 (51.2%) of the females with abnormal waist circumference were hypertensive. The association between abnormal waist circumference and high blood pressure was significant among both sexes, P value = 0.001. Physical exercise and fat and salt foods were not significantly associated waist circumference in both men and women. Conclusion: Two thirds of women and men in the celebrating areas were hypertensive.  Half of women and one third of men were significantly hypertensive and having abnormal waist circumference. Doing physical exercise, avoiding fat and salt foods was insignificantly associated with normal waist circumference. Large survey with representative sample is needed to estimate the real Sudanese waist circumference.

Background: Minutes are crucial in the treatment of out-of-hospital cardiac arrest (CA). Immediate chest compressions and early defibrillation are keys to good outcomes. Local neighborhood volunteer (vol) response programs may decrease delays to early CPR and AED use. We hypothesized that a coordinated effort of alerting trained neighborhood vols simultaneously with 911 activation of professional EMS providers would provide earlier CPR and defibrillation in such communities. Methods: We developed a program of simultaneously alerting CPR and AED trained neighborhood vols and the local EMS system for cardiac arrest events in a retirement community in Southern Arizona, encompassing approximately 17,300 homes and 21,500 residents. EMS services are provided by 5 stations within the community boundaries. Within a single housing development neighborhood, 9 vols and the closest EMS station were involved in 3 days of mock CA notifications (total of 12 different alerts at various times during daytime hours were sent). This provided a total of 120 response opportunities, 12 for EMS and 108 for vols. The distance to the mock event and the time from alert to arrival were recorded and compared. Results: In the selected 55+ neighborhood, the two groups differed significantly in both distance to the mock cardiac arrest event and in response times. The volunteers average 0.33±0.19 miles from the mock CA incidences while the closest EMS station was 3.3 miles from the tested neighborhood (p<0.0001). Response times (time from call to arrival) were also different. The earliest Vol arrived at 1min 30sec±48sec*, 2 Vols & AED at 1min 38 sec±53sec*, all arriving Vols at 3min 23 sec*, and EMS at 7min 20 sec±1min 13sec (*p<0.0001 vs EMS). Conclusion: When the neighborhood volunteers in this testing period were geographically closer to the mock CA event, they arrived significantly sooner to the scene than did the EMS service. The mean time of arrival for at least 2 vols with an AED was 5 min 42 sec faster than the professional rescuers. The implications for such a time saving could be as much as a 240% increase (25% to 85%) in survival for those with shockable rhythms.

Abstract Background The influence of past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events toward willingness to “pay it forward” by helping the next cardiac arrest victim was explored. Methods Using a validated questionnaire, 6248 participants were asked to rate their willingness to perform bystander chest compression with mouth-to-mouth ventilation and chest compression-only CPR. Their past familial experiences of receiving cardiopulmonary resuscitation (CPR) and medical help in various cardiac arrest and nonfatal cardiac events were also recorded. Results Kruskal-Wallis test with post hoc Dunn’s pairwise comparisons showed that the following were significantly more willing to perform CPR with mouth-to-mouth ventilation: familial experience of “nonfatal cardiac events” (mean rank = 447) vs “out-of-hospital cardiac arrest with no CPR” (mean rank = 177), U = 35442.5, z = −2.055, p = 0.04; “in-hospital cardiac arrest and successful CPR” (mean rank = 2955.79) vs “none of these experiences” (mean rank = 2468.38), U = 111903, z = −2.60, p = 0.01; and “in-hospital cardiac arrest with successful CPR” (mean rank = 133.45) vs “out-of-hospital arrest with no CPR” (mean rank = 112.36), U = 4135.5, z = −2.06, p = 0.04. For compression-only CPR, Kruskal-Wallis test with multiple runs of Mann-Whitney U tests showed that “nonfatal cardiac events” group was statistically higher than the group with “none of these experiences” (mean rank = 3061.43 vs 2859.91), U = 1194658, z = −2.588, p = 0.01. The groups of “in-hospital cardiac arrest with successful CPR” and “in-hospital cardiac arrest with transient return of spontaneous circulation” were the most willing groups to perform compression-only CPR. Conclusion Prior familial experiences of receiving CPR and medical help, particularly among those with successful outcomes in a hospital setting, seem to increase the willingness to perform bystander CPR.

AbstractObjective: The objective of this study was to evaluate initial end-tidal CO2 (EtCO2) as a predictor of survival in out-of-hospital cardiac arrest.Methods: This was a retrospective study of all adult, non-traumatic, out-of-hospital, cardiac arrests during 2006 and 2007 in Los Angeles, California. The primary outcome variable was attaining return of spontaneous circulation (ROSC) in the field. All demographic information was reviewed and logistic regression analysis was performed to determine which variables of the cardiac arrest were significantly associated with ROSC.Results: There were 3,121 cardiac arrests included in the study, of which 1,689 (54.4%) were witnessed, and 516 (16.9%) were primary ventricular fibrillation (VF). The mean initial EtCO2 was 18.7 (95%CI = 18.2–19.3) for all patients. Return of spontaneous circulation was achieved in 695 patients (22.4%) for which the mean initial EtCO2 was 27.6 (95%CI = 26.3–29.0). For patients who failed to achieve ROSC, the mean EtCO2 was 16.0 (95%CI = 15.5–16.5). The following variables were significantly associated with achieving ROSC: witnessed arrest (OR = 1.51; 95%CI = 1.07–2.12); initial EtCO2 >10 (OR = 4.79; 95%CI = 3.10–4.42); and EtCO2 dropping <25% during the resuscitation (OR = 2.82; 95%CI = 2.01–3.97).The combination of male gender, lack of bystander cardiopulmonary resuscitation, unwitnessed collapse, non-vfib arrest, initial EtCO2 ≤10 and EtCO2 falling > 25% was 97% predictive of failure to achieve ROSC.Conclusions: An initial EtCO2 >10 and the absence of a falling EtCO2 >25% from baseline were significantly associated with achieving ROSC in out-of-hospital cardiac arrest. These additional variables should be incorporated in termination of resuscitation algorithms in the prehospital setting.

Background Long-term physiological variations, such as seasonal variations, affect the screening efficiency at medical checkups. This study examined the seasonal variation in liver function tests using recently described data-mining methods. Methods The ‘latent reference values’ of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyltransferase ( γGT), cholinesterase (ChE) and total bilirubin (T-Bil) were extracted from a seven-year database of outpatients (aged 20–79 yr; comprising approximately 1,270,000 test results). After calculating the monthly means for each variable, the time-series data were separated into trend and seasonal components using a local regression model (Loess method). Then, a cosine function model (cosinor method) was applied to the seasonal component to determine the periodicity and fluctuation range. A two-year outpatient database (215,000 results) from another hospital was also analysed to confirm the reproducibility of these methods. Results The serum levels of test results tended to increase in the winter. The increase in AST and ALT was about 6% in men and women, and was greater than that in ChE, ALP (in men and women) and γGT (in men). In contrast, T-Bil increased by 3.6% (men) and 5.0% (women) in the summer. The total protein and albumin concentrations did not change significantly. AST and ALT showed similar seasonal variation in both institutions in the comparative analysis. Conclusions The liver function tests were observed to show seasonal variations. These seasonal variations should therefore be taken into consideration when establishing either reference intervals or cut-off values, which are especially important regarding aminotransferases.
