In this study, conducted in collaboration with the Western Australian rock lobster industry during the 1992–93 fishing season, daily records were made on morbidity and mortality of western rock lobsters, Panulirus cygnus, held in commercial shipping (export) cartons. The aims were to measure the rates of morbidity + mortality and to identify patterns of correlation of morbidity + mortality rates for a range of environmental variables recorded by the processors. In three processing units, the rate of morbidity + mortality in simulated live shipments averaged 5á2% (±0·6), with a highly significant difference (P<0·001) between processing units. Three factors, holding time in export cartons, ambient temperature within the export cartons and chilling period before packing lobsters, had the greatest influence on the rate of morbidity + mortality. Morbidity + mortality rate of animals held for 30–36 h (10·4 ± 2·3%) was twice that of animals held for 20–24 h (5·2 ± 0·6%). A positive significant correlation (r = 0·25, P = 0·001) was identified between morbidity + mortality rate and the internal carton temperature. Aprolongation of the chilling period was reflected by improved survival, possibly resulting from an anaesthesic effect of the chilling treatment.

Background: Mortality is important to study population change in the country; infant mortality is considered as principal component balancing the child sex ratio. In this study authors aimed to analyze how mortality rates and child sex ratios are different in urban and rural areas and how its growth statistics are changing over years. Objectives of the study were to quantify infant mortality rates change over time and check the means among mortality indicators.Methods: The study was conducted using secondary data obtained from various issues and reports published by Registrar General and Census Commissioner, India for a period of 10 years from 2006 to 2016. The obtained data on mortality indicators were subjected to basic statistical analysis using percent change and paired t-test.Results: The Infant mortality rate which was reduced by 23 points indicating reduction of 67.65 percent control over a period from 2006 to 2016. Further, results show that, in case of urban mortality, there was significant difference between mortality indicators during study period, the p-value (0.011) was less than level of significance (0.05) so we reject the null hypothesis and it is concluded that there is significant difference between the means of urban mortality indicators over a period of from 2006 to 2016.Conclusions: The infant mortality rate frequently provided as a key indicator of overall the development. There is need for stable child sex ratio; health of children and women are essential for better growth and reaching stable child sex ratio for the ever increasing population.

Abstract Patients with incarcerated abdominal wall hernias (AWHs) are often encountered in emergency care units. Despite advances in anesthesia, antisepsis, antibiotic therapy, and fluid therapy, the morbidity and mortality rates for these patients remain high. Between 2006 and 2011, we retrospectively analyzed the cases of 131 patients who underwent emergency surgery for incarcerated abdominal wall hernias. Of these, there were 70 women (53.4%) and 61 men (46.6%) with an average age of 63.3 ± 17.4 years (range, 17–91 years). Morbidity was observed in 28 patients (21.4%), and the mortality rate was 2.3%. Intestinal resection, presence of concomitant disease, and general anesthesia were the independent variants that affected morbidity of patients with incarcerated abdominal wall hernias.

Summary Objective: To determine whether a private HIS could have detected the influenza epidemic outbreaks earlier through changes in morbidity and mortality patterns. Methods: Data Source included a health information system (HIS) from an academic tertiary health care center integrating administrative and clinical applications. It used a local interface terminology server which provides support through data autocoding of clinical documentation. Specific data subsets were created to compare the burden of influenza during the epidemiological week (EW) 21 to 26 for years 2007 to 2009 among 150,000 Health Maintenance Organization members in Argentina. The threshold for identifying an epidemic was considered met when the weekly influenza-like illness (ILI) rate exceeded 200 per 100,000 visits. Case fatality rates and mortality rates of severe acute respiratory infection (SARI) from 2007 to 2009 were retrospectively compared. Case fatality rates and mortality rates for A/H1N1 influenza 2009 also were estimated. Results: The HIS detected the outbreak in EW 23 while the government Ministry of Health (MoH) gave a national epidemic alert during EW 25. The number of visits for ILI increased more than fourfold when comparing 2009 to the period 2007-2008. The SARI mortality rate in 2009 was higher than in 2008 (RR 2.8; 95%CI 1.18-6.63) and similar to that of 2007 (RR 1.05; 95%CI 0.56-1.49). 2009 was the first year with mortalities younger than 65 years attributable to SARI. The estimated A/H1N1 case fatality rate for SARI was 6.2% (95%CI 2.5 to 15.5) and A/H1N1 mortality rate was 6 per 100,000 (95%CI 0 to 11.6). Conclusion: Our HIS detected the outbreak two weeks before than the MoH gave a national alert. The information system was useful in assessing morbidity and mortality during the 2009 influenza epidemic H1N1 outbreak suggesting that with a private-public integration a more real-time outbreak and disease surveillance system could be implemented.

Abstract Background and study aims Over-the-scope clip (OTSC) has been recently used in management of gastrointestinal perforations, but data on it are still limited. The aim of this study was to compare management of iatrogenic perforations before and after the OTSC was available in our endoscopy unit. Patients and methods We conducted a monocentric retrospective study from June 2007 to June 2015. All iatrogenic gastrointestinal perforations detected during endoscopy were included. Two time periods were compared in terms of surgery and mortality rates: before use of OTSC (June 2007 to June 2011) and after OTSC became available (June 2011 to June 2015). Results During the first period, 24 perforations were recorded. Fifteen (62.5 %) were managed with surgery. The mortality rate was 8 %. During the second period, 16 perforations occurred. In 11 patients (68.7 %), an OTSC was used to close the perforation, with complete sealing of the perforation in 100 % of cases. However, 2 patients with sigmoid perforation had to undergo surgery due to right ureteral obstruction by the clip in 1 case and to presence of a localized peritonitis in the other. The surgery rate during this period was 12.5 % (2 /16), with a statistically significant difference compared to the first period (P = 0.002). There was no mortality in the second period versus 8 % in the first one (P = 0.23). Conclusions OTSC is effective for endoluminal closure of iatrogenic perforations and results in a significant decrease in surgery rate.

ObjectivesMany of critically ill patients are being cared for prolonged periods in ED just because of limited number of ICU beds and utilize of ED as the entry point to the health care system. The aim of this study is evaluation efficiency of APACHE III scoring system in predicting mortality rate of the mentioned patients.Materials and MethodsThis cross-sectional, observational, analytic study was performed in one year period. A hundred patients remaining in ED and necessitating ICU hospitalizing were enrolled by the convenience type of non-probability sampling. Then, the APACHE III scores, predicted and observed mortality rates were calculated using of information obtained from patients' files, interview with the patients' family and performing required physical exams and lab tests.ResultsIn the assessment of 100 patients, men group were 56% (56) and women group 44% (44). The age of patients and the ED lengths of stay were 66.07 ± 19.92 years and 5.11 ± 3.79 days respectively. The average (± SD) of APACHE III score of the enrolled patients was 58.89 ± 18.24 and the predicted mortality rate calculated 32.73%; while, the total of observed mortality rate was 55%. The average (± SD) of APACHE III score of survivors and non-survivors were 48.63 ± 16.35 and 67.63 ± 14.84 respectively. So, there was a significant deference (p < 0.001). Also, there was a significant deference in the ED lengths of stay between survivors and non-survivors (3.20 ± 1.34 and 6.57 ± 4.40 respectively, p < 0.001).ConclusionIn our study, APACHE III score and ED lengths of stay were higher versus other studies in Iran and other countries; which show more critical patients presenting to our hospital and limited ICU beds versus patients. This study results nevertheless there was significant difference between predicted and observed mortality rates, the APACHE III scoring system is applicable to evaluating care, treatment and prognosis of ED patients, as is used in ICU.

Background: Aim of this study is to examine the efficacy of Physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and Portsmouth predictor modification (P-POSSUM) equations in predicting morbidity and mortality in patients undergoing emergency laparotomy, to study the morbidity and mortality patterns in patients undergoing emergency laparotomy at Malla Reddy Institute of Medical Sciences, Hyderabad. Methods: The study was conducted for a period of 2 years from February 2018 to February 2020. 100 Patients undergoing emergency laparotomy were studied in the Department of General surgery MRIMS, Hyderabad. POSSUM and P-POSSUM scores are used to predict mortality and morbidity. The ratio of observed to expected deaths (O:E ratio) was calculated for each analysis. Results: The study included total 100 patients, 83 men and 17 women. Observed mortality rate was compared to mortality rate with POSSUM, the O:E ratio was 0.62, and there was no significant difference between the observed and predicted values (χ²=10.79, 9 degree of freedom (df) p=0.148). Observed morbidity rates were compared to morbidity rates predicted by POSSUM, there was no significant difference between the observed and predicted values (χ²=9.89, 9 df, p=0.195) and the overall O:E ratio was 0.91. P-POSSUM predicted mortality equally well when the linear method of analysis was used, with an O:E ratio of 0.65 and no significant difference between the observed and predicted values (χ²= 5.33, 9 df, p= 0.617).Conclusion: POSSUM and P-POSSUM scoring is an accurate predictor of mortality and morbidity following emergency laparotomy and is a valid means of assessing adequacy of care provided to the patient.

Abstract Aim To determine if the outcomes and rate of complications differ based on choice of implant for unstable hip fractures. Method Retrospective analysis of 105 hip fractures operated in 2015 + 2016 with AO classification A2.2. A2.3 or A3. These were divided into 2 groups depending on whether DHS/Plate implant was selected (n = 86) or Nail implant was used (n = 19). Any complications occurring in their subsequent management or performance of any revision procedures were recorded. 6-month mortality rate was also calculated for both groups. Results When A2 and A3 fractures were assessed together the rate of acute complications was similar in both groups. 21% for nails and 19% for plates. The rate of delayed complications was not significantly different either, 16% for nails and 10% for plates. Revision procedures were more common where nails had been used (16%) compared to only 6% of plate fixations. Mortality rates were identical. When looking at A3 fractures in isolation, the rate of delayed complications is significantly higher when plates are used (24%) compared to 12% when nails are selected. Conclusions We did not identify any significant difference in acute complications including bleeding and infection based on choice of implant. This goes against common arguments raised against use of nails. Successful use of DHS fixation in unstable A2 hip fractures is possible, as evidenced by similar rates of delayed complications. Revisions were higher when nail was selected. It is however noted that for reverse oblique fractures nails perform demonstrably better, with half as frequent delayed complications and revisions.

Abstract Background Hip fractures are associated with notable mortality rates in elderly patients. The purpose of the study was to evaluate the mortality rate and influencing factors associated with mortality in the elderly patients with hip fractures. Methods Between October 2000 and December 2009, 807 elderly patients with hip fractures were enrolled in this study. There were 197 men and 610 women. The mean age at injuries were 78 years (range, 65–99 years). The fractures consisted of 390 femoral neck fractures and 417 intertrochanteric fractures. The mortality rate was evaluated between patients who underwent surgical and nonsurgical treatments. The influencing factors associated with mortality rate were evaluated statistically. Results Overall, 691 (85.6%) patients treated surgically and 116 (14.4%) patients treated nonsurgically were included. The overall mortality rates one and two years after injuries were 16.6 and 39.4%, respectively. In surgical treatment group, the mortality rate one and two years after injuries were 12.0 and 35.7%, respectively. In nonsurgical treatment group, the mortality rates were 44.0 and 61.2%, respectively (p < 0.05). No significant difference was noted between the types of fractures and the time from injury to surgery. Regardless of surgical methods, a significantly higher mortality rate was observed in patients with heart disease, chronic renal disease, dementia, and cancer, or in patients with 3 or more comorbidities. Conclusions In elderly patients with hip fractures, surgical treatments can decrease the mortality rate as compared with nonsurgical treatments. In addition, patients who had three or more comorbidities (heart disease, chronic renal failure, dementia, and history of cancer) are associated with a higher risk of mortality.

The study monitored the effect of the housing system and the number of animals transported together on transport-induced mortality of slaughter pigs in the Czech Republic in the period from 2004 to 2008. Concerning the type of housing during the fattening, the lowest mortality rate during the subsequent transport to slaughter houses was detected among pigs fattened on solid floor (0.047%) and on deep bedding (0.084%). The highest mortality during transport was detected among pigs fattened on fully or partially slatted floor (0.139%), a significant difference (p < 0.01) was found compared to other housing types. Assessment of the influence of individual pig load size on mortality showed the lowest mortality among pigs transported in loads of up to 40 animals (0.053%). Mortality during the transport in loads of the size of 41 to 120 animals was 0.130%, and for loads of the size over 120 pigs the mortality rate was 0.156%. These mortality rates are significantly higher (p < 0.01) compared to the load sizes of up to 40 animals.

Objective: This study aimed to evaluate the timing of tracheostomy and relationship to outcomes (length of hospital stay, length of mechanical ventilation, morbidity and mortality rate) in adults with moderate and severe tetanus.  Methods:             Design:           Cross-Sectional Study             Setting:           Tertiary Government Training Hospital             Patients:         All adult patients (19 years old and above) diagnosed with moderate and    severe stage tetanus from January 2015 to January 2018 were considered for inclusion. Results: There were 109 patients included in this study, majority were males (n=95) with a male to female ratio of 7:1. Most belonged to the 51-60 years age group (mean: 53.7 SD: +/-16.1). Based on Cole Tetanus staging, the majority presented with severe stage tetanus (67.9%; n=74). Only 35.8% (n=39) were admitted at the Intensive Care Unit. Early tracheostomy was performed in 56.0% (n=61) of the patients (mean 6.3 hours SD: +/- 4.61). Mortality rate was noted to be 52.3% (n=57). Overall, early tracheostomy among moderate to severe stage tetanus patients showed shorter length of hospital stay and length of mechanical ventilation than  late tracheostomy (tracheostomy >24 hours) (p-value < .05). However, no significant difference was noted for timing of tracheostomy in terms of morbidity and mortality rate (p-value > .05). Conclusion: Early tracheostomy within less than 24 hours from time of admission for moderate and severe tetanus is associated with shorter length of hospital stay and mechanical ventilation than late tracheostomy, and may play a role in tetanus management.
