Abstract: Purpose The incidence of inguinal hernia is higher in elderly because of aging-related diseases like prostatism, bronchitis, collagen laxity. A conservative management is common in elderly to reduce surgery-related risks, however watchful waiting can expose to obstruction and strangulation. The aim of the present study was to assess the impact of emergency surgery in a large series of elderly with complicated groin hernia and to identify the independent risk factors for postoperative morbidity and mortality. The predictive performance of prognostic risk scores has been also assessed. Methods This is a prospective observational study carried out between January 2017 and June 2018 in elderly patients who underwent emergency surgery for complicated hernia in 38 Italian hospitals. Pre-operative, surgical and postoperative data were recorded for each patient. ASA score, Charlson’s comorbidity index, P-POSSUM and CR-POSSUM were assessed. Results 259 patients were recruited, mean age was 80 years. A direct repair without mesh was performed in 62 (23.9%) patients. Explorative laparotomy was performed in 56 (21.6%) patients and bowel resection was necessary in 44 (17%). Mortality occurred in seven (2.8%) patients. Fifty-five (21.2%) patients developed complications, 12 of whom had a major one. At univariate and multivariate analyses, Charlson’s comorbidity index ≥ 6, altered mental status, and need for laparotomy were associated with major complications and mortality Conclusion Emergency surgery for complicated hernia is burdened by high morbidity and mortality in elderly patients. Preoperative comorbidity played a pivotal role in predicting complications and mortality and therefore Charlson’s comorbidity index could be adopted to select patients for elective operation

Abstract: Background: A limited number of studies investigating perioperative risk factors associated with emergency appendectomy in elderly patients have been published to date. Whether older age may be associated with poorer outcomes following appendectomy is still a matter of debate. The primary aim of this study was to determine the predictors of postoperative morbidity following appendectomy in patients aged ≥ 65years. Methods: Data regarding all elderly patients who underwent emergency appendectomy from January 2017 to June 2018 admitted 36 Italian surgical departments were prospectively collected and analyzed. Baseline demographics and perioperative variables were evaluated. Uni- and multivariate analyses adjusted for differences between groups were carried out to determine possible predictors of adverse outcomes after appendectomy. Results: Between January 2017 and June 2018, 135 patients aged ≥ 65years with a diagnosis of AA met the study inclusion criteria. Twenty-six patients (19.3%) were diagnosed with some type of postoperative complication. Decreasing the preoperative hemoglobin level showed a statistically significant association with postoperative complications (OR 0.77, CI 0.61–0.97, P = 0.03). Preoperative creatinine level (P = 0.02, OR 2.04, CI 1.12–3.72), and open appendectomy (P = 0.03, OR 2.67, CI 1.11–6.38) were significantly associated with postoperative morbidity. After adjustment, the only independent predictor of postoperative morbidity was preoperative creatinine level (P = 0.04, OR 2.01, CI 1.05–3.89). Conclusions: In elderly patients with AA, perioperative risk assessment in the emergency setting must be as accurate as possible to identify modifiable risk factors that can be addressed before surgery, such as preoperative hemoglobin and creatinine levels.

Subjects: acute care surgery, SIRS, elderly, frailty, metabolic syndrome
Abstract: Patients with MetS or SIRS experience higher rates of mortality and morbidity, across both cardiac and noncardiac surgery. Frailty assessment has acquired increasing importance in recent years as it predisposes elderly patients to a worse outcome. The aim of our study was to investigate the influence of MetS, SIRS, and with or without frailty on elderly patients undergoing emergency surgical procedures.We analyzed data of all patients with nonmalignant diseases requiring an emergency surgical procedure from January 2017 to December 2020. The occurrence of MetS was identified using modified definition criteria used by the NCEP-ATP III Expert Panel: obesity, hypertension, diabetes, or if medication for high triglycerides or for low HDL cholesterol was taken. Systemic inflammatory response syndrome (SIRS) was evaluated according to the original consensus study (Sepsis-1). The frailty profile was investigated by the 5-modified Frailty Index (5-mFI) and the Emergency Surgery Frailty Index (EmSFI). Postoperative complications have been reported and categorized according to the Clavien-Dindo (C-D) classification system. Morbidity and mortality have been mainly considered as the 30-day standard period definition.Of the 2,318 patients included in this study, 1,010 (43.6%) fulfilled the criteria for MetS (MetsG group). Both 5-Items score and EmsFI showed greater fragility in patients with MetS. All patients with MetS showed more frequently a CACI index greater than 6. The occurrence of SIRS was higher in MetSG. LOS was longer in patients with MetS (MetSG 11.4 ± 12 days vs.Impact of MetS and SIRS on elderly surgical patient outcomes has yet to be fully elucidated. The present study showed a 43.6% incidence of MetS in the elderly population. In conclusion, age per se should be not considered anymore as the main variable to estimate patient outcomes, while MetS and Frailty should have always a pivotal role.

Abstract: Gastrointestinal emergencies (GE) are frequently encountered in emergency department (ED), and patients can present with wide-ranging symptoms. more than 3 million patients admitted to US hospitals each year for EGS diagnoses, more than the sum of all new cancer diagnoses. In addition to the complexity of the urgent surgical patient (often suffering from multiple co-morbidities), there is the unpredictability and the severity of the event. In the light of this, these patients need a rapid decision-making process that allows a correct diagnosis and an adequate and timely treatment. The primary endpoint of this Italian nationwide study is to analyze the clinicopathological findings, management strategies and short-term outcomes of gastrointestinal emergency procedures performed in patients over 18. Secondary endpoints will be to evaluate to analyze the prognostic role of existing risk-scores to define the most suitable scoring system for gastro-intestinal surgical emergency. The primary outcomes are 30-day overall postoperative morbidity and mortality rates. Secondary outcomes are 30-day postoperative morbidity and mortality rates, stratified for each procedure or cause of intervention, length of hospital stay, admission and length of stay in ICU, and place of discharge (home or rehabilitation or care facility). In conclusion, to improve the level of care that should be reserved for these patients, we aim to analyze the clinicopathological findings, management strategies and short-term outcomes of gastrointestinal emergency procedures performed in patients over 18, to analyze the prognostic role of existing risk-scores and to define new tools suitable for EGS. This process could ameliorate outcomes and avoid futile treatments. These results may potentially influence the survival of many high-risk EGS procedure.

Abstract: As the world population is aging rapidly, emergency abdominal surgery for acute abdomen in the elderly represents a global issue, both in developed and developing countries. Data regarding all the elderly patients who underwent emergency abdominal surgery from January 2017 to December 2017 at 36 Italian surgical departments were analyzed with the aim to appraise the contemporary reality regarding the use of emergency laparoscopy for acute abdomen in the elderly. 1993 patients were enrolled. 1369 (68.7%) patients were operated with an open technique; whereas, 624 (31.3%) underwent a laparoscopic operation. The postoperative morbidity rate was 32.6%, with a statically significant difference between the open and the laparoscopic groups (36.2% versus 22.1%, p < 0.001). The reported mortality rate was 8.8%, with a statistically significant difference between the open and the laparoscopic groups (11.2% versus 2.2%, p < 0.001). Our results demonstrated that patients in the ASA II (58.1%), ASA III (68.7%) and ASA IV (88.5%) groups were operated with the traditional open technique in most of the cases. Only a small percentage of patients underwent laparoscopy for perforated gastro-duodenal ulcer repair (18.9%), adhesiolyses with/without small bowel resection (12.2%), and large bowel resection (10.7%). Conversion to open technique was associated with a higher mortality rate (11.1% versus 2.2%, p < 0.001) and overall morbidity (38.9% versus 22.1%, p = 0.001) compared with patients who did not undergo conversion. High creatinine (p < 0.001) and glycaemia (p = 0.006) levels, low hemoglobin levels (p < 0.001), oral anticoagulation therapy (p = 0.001), acute respiratory failure (p < 0.001), presence of malignancy (p = 0.001), SIRS (p < 0.001) and open surgical approach (p < 0.001) were associated with an increased risk of postoperative morbidity. Regardless of technical progress, elderly patients undergoing emergency surgery are at very high risk for in-hos

Abstract: Purpose: The incidence of inguinal hernia is higher in elderly because of aging-related diseases like prostatism, bronchitis, collagen laxity. A conservative management is common in elderly to reduce surgery-related risks, however watchful waiting can expose to obstruction and strangulation. The aim of the present study was to assess the impact of emergency surgery in a large series of elderly with complicated groin hernia and to identify the independent risk factors for postoperative morbidity and mortality. The predictive performance of prognostic risk scores has been also assessed. Methods: This is a prospective observational study carried out between January 2017 and June 2018 in elderly patients who underwent emergency surgery for complicated hernia in 38 Italian hospitals. Pre-operative, surgical and postoperative data were recorded for each patient. ASA score, Charlson’s comorbidity index, P-POSSUM and CR-POSSUM were assessed. Results: 259 patients were recruited, mean age was 80 years. A direct repair without mesh was performed in 62 (23.9%) patients. Explorative laparotomy was performed in 56 (21.6%) patients and bowel resection was necessary in 44 (17%). Mortality occurred in seven (2.8%) patients. Fifty-five (21.2%) patients developed complications, 12 of whom had a major one. At univariate and multivariate analyses, Charlson’s comorbidity index ≥ 6, altered mental status, and need for laparotomy were associated with major complications and mortality Conclusion: Emergency surgery for complicated hernia is burdened by high morbidity and mortality in elderly patients. Preoperative comorbidity played a pivotal role in predicting complications and mortality and therefore Charlson’s comorbidity index could be adopted to select patients for elective operation.

Abstract: As the world population is aging rapidly, emergency abdominal surgery for acute abdomen in the elderly represents a global issue, both in developed and developing countries. Data regarding all the elderly patients who underwent emergency abdominal surgery from January 2017 to December 2017 at 36 Italian surgical departments were analyzed with the aim to appraise the contemporary reality regarding the use of emergency laparoscopy for acute abdomen in the elderly. 1993 patients were enrolled. 1369 (68.7%) patients were operated with an open technique; whereas, 624 (31.3%) underwent a laparoscopic operation. The postoperative morbidity rate was 32.6%, with a statically significant difference between the open and the laparoscopic groups (36.2% versus 22.1%, p < 0.001). The reported mortality rate was 8.8%, with a statistically significant difference between the open and the laparoscopic groups (11.2% versus 2.2%, p < 0.001). Our results demonstrated that patients in the ASA II (58.1%), ASA III (68.7%) and ASA IV (88.5%) groups were operated with the traditional open technique in most of the cases. Only a small percentage of patients underwent laparoscopy for perforated gastro-duodenal ulcer repair (18.9%), adhesiolyses with/without small bowel resection (12.2%), and large bowel resection (10.7%). Conversion to open technique was associated with a higher mortality rate (11.1% versus 2.2%, p < 0.001) and overall morbidity (38.9% versus 22.1%, p = 0.001) compared with patients who did not undergo conversion. High creatinine (p < 0.001) and glycaemia (p = 0.006) levels, low hemoglobin levels (p < 0.001), oral anticoagulation therapy (p = 0.001), acute respiratory failure (p < 0.001), presence of malignancy (p = 0.001), SIRS (p < 0.001) and open surgical approach (p < 0.001) were associated with an increased risk of postoperative morbidity. Regardless of technical progress, elderly patients undergoing emergency surgery are at very high risk for in-hospital complications. A detailed analysis of complications and mortality in the present study showed that almost 9% of elderly patients died after surgery for acute abdomen, and over 32% developed complications.

Abstract: Background Frailty assessment has acquired an increasing importance in recent years and it has been demonstrated that this vulnerable profile predisposes elderly patients to a worse outcome after surgery. Therefore, it becomes paramount to perform an accurate stratification of surgical risk in elderly undergoing emergency surgery. Study design 1024 patients older than 65 years who required urgent surgical procedures were prospectively recruited from 38 Italian centers participating to the multicentric FRAILESEL (Frailty and Emergency Surgery in the Elderly) study, between December 2016 and May 2017. A univariate analysis was carried out, with the purpose of developing a frailty index in emergency surgery called “EmSFI”. Receiver operating characteristic curve analysis was then performed to test the accuracy of our predictive score. Results 784 elderly patients were consecutively enrolled, constituting the development set and results were validated considering further 240 consecutive patients undergoing colorectal surgical procedures. A logistic regression analysis was performed identifying different EmSFI risk classes. The model exhibited good accuracy as regard to mortality for both the development set (AUC = 0.731 [95% CI 0.654–0.772]; HL test χ2 = 6.780; p = 0.238) and the validation set (AUC = 0.762 [95% CI 0.682–0.842]; HL test χ2 = 7.238; p = 0.299). As concern morbidity, our model showed a moderate accuracy in the development group, whereas a poor discrimination ability was observed in the validation cohort. Conclusions The validated EmSFI represents a reliable and time-sparing tool, despite its discriminative value decreased regarding complications. Thus, further studies are needed to investigate specifically surgical settings, validating the EmSFI prognostic role in assessing the procedure-related morbidity risk.

Abstract: Improvements in living conditions and progress in medical management have resulted in better quality of life and longer life expectancy. Therefore, the number of older people undergoing surgery is increasing. Frailty is often described as a syndrome in aged patients where there is augmented vulnerability due to progressive loss of functional reserves. Studies suggest that frailty predisposes elderly to worsening outcome after surgery. Since emergency surgery is associated with higher mortality rates, it is paramount to have an accurate stratification of surgical risk in such patients. The aim of our study is to characterize the clinicopathological findings, management, and short-term outcome of elderly patients undergoing emergency surgery. The secondary objectives are to evaluate the presence and influence of frailty and analyze the prognostic role of existing risk-scores. The final FRAILESEL protocol was approved by the Ethical Committee of “Sapienza” University of Rome, Italy. The FRAILESEL study is a nationwide, Italian, multicenter, observational study conducted through a resident-led model. Patients over 65 years of age who require emergency surgical procedures will be included in this study. The primary outcome measures are 30-day postoperative mortality and morbidity rates. The Clavien-Dindo classification system is used to categorize complications. The secondary outcome measures include length of hospital stay, length of stay in intensive care unit, and predictive value for morbidity and mortality of several frailty and surgical risk-scores. The results of the FRAILESEL study will be disseminated through national and international conference presentations and peer-reviewed journals. The study is also registered at ClinicalTrials.gov (ClinicalTrials.gov identifier: NCT02825082).

Abstract: Purpose: The incidence of inguinal hernia is higher in elderly because of aging-related diseases like prostatism, bronchitis, collagen laxity. A conservative management is common in elderly to reduce surgery-related risks, however watchful waiting can expose to obstruction and strangulation. The aim of the present study was to assess the impact of emergency surgery in a large series of elderly with complicated groin hernia and to identify the independent risk factors for postoperative morbidity and mortality. The predictive performance of prognostic risk scores has been also assessed. Methods: This is a prospective observational study carried out between January 2017 and June 2018 in elderly patients who underwent emergency surgery for complicated hernia in 38 Italian hospitals. Pre-operative, surgical and postoperative data were recorded for each patient. ASA score, Charlson’s comorbidity index, P-POSSUM and CR-POSSUM were assessed. Results: 259 patients were recruited, mean age was 80 years. A direct repair without mesh was performed in 62 (23.9%) patients. Explorative laparotomy was performed in 56 (21.6%) patients and bowel resection was necessary in 44 (17%). Mortality occurred in seven (2.8%) patients. Fifty-five (21.2%) patients developed complications, 12 of whom had a major one. At univariate and multivariate analyses, Charlson’s comorbidity index ≥ 6, altered mental status, and need for laparotomy were associated with major complications and mortality Conclusion: Emergency surgery for complicated hernia is burdened by high morbidity and mortality in elderly patients. Preoperative comorbidity played a pivotal role in predicting complications and mortality and therefore Charlson’s comorbidity index could be adopted to select patients for elective operation.

Abstract: As the world population is aging rapidly, emergency abdominal surgery for acute abdomen in the elderly represents a global issue, both in developed and developing countries. Data regarding all the elderly patients who underwent emergency abdominal surgery from January 2017 to December 2017 at 36 Italian surgical departments were analyzed with the aim to appraise the contemporary reality regarding the use of emergency laparoscopy for acute abdomen in the elderly. 1993 patients were enrolled. 1369 (68.7%) patients were operated with an open technique; whereas, 624 (31.3%) underwent a laparoscopic operation. The postoperative morbidity rate was 32.6%, with a statically significant difference between the open and the laparoscopic groups (36.2% versus 22.1%, p < 0.001). The reported mortality rate was 8.8%, with a statistically significant difference between the open and the laparoscopic groups (11.2% versus 2.2%, p < 0.001). Our results demonstrated that patients in the ASA II (58.1%), ASA III (68.7%) and ASA IV (88.5%) groups were operated with the traditional open technique in most of the cases. Only a small percentage of patients underwent laparoscopy for perforated gastro-duodenal ulcer repair (18.9%), adhesiolyses with/without small bowel resection (12.2%), and large bowel resection (10.7%). Conversion to open technique was associated with a higher mortality rate (11.1% versus 2.2%, p < 0.001) and overall morbidity (38.9% versus 22.1%, p = 0.001) compared with patients who did not undergo conversion. High creatinine (p < 0.001) and glycaemia (p = 0.006) levels, low hemoglobin levels (p < 0.001), oral anticoagulation therapy (p = 0.001), acute respiratory failure (p < 0.001), presence of malignancy (p = 0.001), SIRS (p < 0.001) and open surgical approach (p < 0.001) were associated with an increased risk of postoperative morbidity. Regardless of technical progress, elderly patients undergoing emergency surgery are at very high risk for in-hospital complications. A d

Abstract: Improvements in living conditions and progress in medical management have resulted in better quality of life and longer life expectancy. Therefore, the number of older people undergoing surgery is increasing. Frailty is often described as a syndrome in aged patients where there is augmented vulnerability due to progressive loss of functional reserves. Studies suggest that frailty predisposes elderly to worsening outcome after surgery. Since emergency surgery is associated with higher mortality rates, it is paramount to have an accurate stratification of surgical risk in such patients. The aim of our study is to characterize the clinicopathological findings, management, and short-term outcome of elderly patients undergoing emergency surgery. The secondary objectives are to evaluate the presence and influence of frailty and analyze the prognostic role of existing risk-scores. The final FRAILESEL protocol was approved by the Ethical Committee of “Sapienza” University of Rome, Italy. The FRAILESEL study is a nationwide, Italian, multicenter, observational study conducted through a resident-led model. Patients over 65years of age who require emergency surgical procedures will be included in this study. The primary outcome measures are 30-day postoperative mortality and morbidity rates. The Clavien-Dindo classification system is used to categorize complications. The secondary outcome measures include length of hospital stay, length of stay in intensive care unit, and predictive value for morbidity and mortality of several frailty and surgical risk-scores. The results of the FRAILESEL study will be disseminated through national and international conference presentations and peer-reviewed journals. The study is also registered at ClinicalTrials.gov (ClinicalTrials.gov identifier: NCT02825082).

Abstract: Background: A limited number of studies investigating perioperative risk factors associated with emergency appendectomy in elderly patients have been published to date. Whether older age may be associated with poorer outcomes following appendectomy is still a matter of debate. The primary aim of this study was to determine the predictors of postoperative morbidity following appendectomy in patients aged ≥ 65 years. Methods: Data regarding all elderly patients who underwent emergency appendectomy from January 2017 to June 2018 admitted 36 Italian surgical departments were prospectively collected and analyzed. Baseline demographics and perioperative variables were evaluated. Uni- and multivariate analyses adjusted for differences between groups were carried out to determine possible predictors of adverse outcomes after appendectomy. Results: Between January 2017 and June 2018, 135 patients aged ≥ 65 years with a diagnosis of AA met the study inclusion criteria. Twenty-six patients (19.3%) were diagnosed with some type of postoperative complication. Decreasing the preoperative hemoglobin level showed a statistically significant association with postoperative complications (OR 0.77, CI 0.61–0.97, P = 0.03). Preoperative creatinine level (P = 0.02, OR 2.04, CI 1.12–3.72), and open appendectomy (P = 0.03, OR 2.67, CI 1.11–6.38) were significantly associated with postoperative morbidity. After adjustment, the only independent predictor of postoperative morbidity was preoperative creatinine level (P = 0.04, OR 2.01, CI 1.05–3.89). Conclusions: In elderly patients with AA, perioperative risk assessment in the emergency setting must be as accurate as possible to identify modifiable risk factors that can be addressed before surgery, such as preoperative hemoglobin and creatinine levels.

Abstract: Purpose: Increasing pressure pushes towards the objective competence assessment of clinical operators. Hand motion analysis (HMA) was introduced to measure surgical and clinical procedures; its recent application to FAST examinations leaves unsolved issues. This study aimed at determining optimal HMA parameters to discriminate between operators’ skill levels, and which FAST tasks are experience-dependent. Methods: Ten experienced (EG) and 13 beginner (BG) sonographers performed a FAST examination on one female and one male model. A motion capture system returned the duration, working volume, number of movements (absolute and time normalized), and hand path length (absolute and time normalized) of each view. Results: BG took more time in completing specific views, with a higher working volume (p = 0.003) and longer hands path (p < 0.001). The number of movements was lower in the EG (p < 0.001) and differed between views (p = 0.014). No significant Group/Model differences were found for the normalized number of movements. The LUQ view required a higher number of movements (p < 0.001). Conclusions: HMA identified kinematic parameters discriminating between proficiency level and critical subtasks in the FAST examination. These findings could be the base for a focused HMA-based evaluation of performances following a proctored training period. There is room to incorporate HMA into simulation metrics and evidence-based credentialing standards for clinical ultrasound applications.

20. Measurements and models of the temperature change of water samples in Sea Surface Temperature buckets

Author: Carella, G., Morris, A.K.R., Pascal, R.W., Yelland, M.J., Berry, D.I., Morak-Bozzo, S., Merchant, C.J., and Kent, E.
Abstract: Uncertainty in the bias adjustments applied to historical sea surface temperature (SST) measurements made using buckets are thought to make the largest contribution to uncertainty in global surface temperature trends. Measurements of the change in temperature of water samples in wooden and canvas buckets used before World War 2 are compared with the predictions of models that have been used to estimate bias adjustments applied in widely-used gridded analyses of SST. The results show that the models are broadly able to predict the dependence of the temperature change of the water over time on the thermal forcing and the bucket characteristics: volume and geometry; structure and material. However, assumptions inherent in the derivation of the models are likely to affect their applicability. We observed that the water sample needed to be fairly vigorously stirred to agree with results from the model, which assumes well-mixed conditions. There were inconsistences between the model results and previous measurements made in a wind tunnel in 1951. The model assumes non turbulent incident flow and consequently predicts an approximately square-root dependence on airflow speed. The wind tunnel measurements, taken over a wide range of airflows, showed a much stronger dependence. In the presence of turbulence the heat transfer will increase with the turbulent intensity: for measurements made on ships the incident airflow is likely to be turbulent and the intensity of the turbulence is always unknown. Taken together these uncertainties are expected to be substantial and may represent the limiting factor for the direct application of these models to adjust historical SST observations. However, both the models and the observations indicate that the most important parameter driving temperature biases in historical bucket measurements is the difference between the water temperature and the wet-bulb temperature. Solar radiation is also important, but not examined in this paper.

25. Estimating sea surface temperature measurement methods using characteristic differences in the diurnal cycle

Abstract: Lack of reliable observational metadata represents a key barrier to understanding sea surface temperature (SST) measurement biases, a large contributor to uncertainty in the global surface record. We present a method to identify SST measurement practice by comparing the observed SST diurnal cycle from individual ships with a reference from drifting buoys under similar conditions of wind and solar radiation. Compared to existing estimates, we found a larger number of engine room-intake (ERI) reports post–World War II and in the period 1960–1980. Differences in the inferred mixture of observations lead to a systematic warmer shift of the bias adjusted SST anomalies from 1980 compared to previous estimates, while reducing the ensemble spread. Changes in mean field differences between bucket and ERI SST anomalies in the Northern Hemisphere over the period 1955–1995 could be as large as 0.5°C and are not well reproduced by current bias adjustment models.

Abstract: Improvements in living conditions and progress in medical management have resulted in better quality of life and longer life expectancy. Therefore, the number of older people undergoing surgery is increasing. Frailty is often described as a syndrome in aged patients where there is augmented vulnerability due to progressive loss of functional reserves. Studies suggest that frailty predisposes elderly to worsening outcome after surgery. Since emergency surgery is associated with higher mortality rates, it is paramount to have an accurate stratification of surgical risk in such patients. The aim of our study is to characterize the clinicopathological findings, management, and short-term outcome of elderly patients undergoing emergency surgery. The secondary objectives are to evaluate the presence and influence of frailty and analyze the prognostic role of existing risk-scores. The final FRAILESEL protocol was approved by the Ethical Committee of “Sapienza” University of Rome, Italy. The FRAILESEL study is a nationwide, Italian, multicenter, observational study conducted through a resident-led model. Patients over 65 years of age who require emergency surgical procedures will be included in this study. The primary outcome measures are 30-day postoperative mortality and morbidity rates. The Clavien-Dindo classification system is used to categorize complications. The secondary outcome measures include length of hospital stay, length of stay in intensive care unit, and predictive value for morbidity and mortality of several frailty and surgical risk-scores. The results of the FRAILESEL study will be disseminated through national and international conference presentations and peer-reviewed journals. The study is also registered at ClinicalTrials.gov (ClinicalTrials.gov identifier: NCT02825082).

30. Climatological diurnal variability in sea surface temperature characterized from drifting buoy data

Author: Morak-Bozzo, S., Merchant, C. J., Kent, E. C., Berry, D. I., and Carella, G.
Abstract: Drifting buoy sea-surface temperature (SST) records have been used to characterize the diurnal variability of ocean tem- perature at a depth of order 20 cm. We use measurements covering the period 1986–2012 from the International Com- prehensive Ocean-Atmosphere Data Set (ICOADS) version 2.5, which is a collection of marine surface observations that includes individual SST records from drifting buoys. Appropriately transformed, this dataset is well suited for estimation of the diurnal cycle, since many drifting buoys have high temporal coverage (many reports per day), and are globally distributed. For each drifter for each day, we compute the local-time daily SST variation relative to the local-time daily mean SST. Climatological estimates of subdaily SST variability are found by averaging across various strata of the data: in 10° latitudinal bands as well as globally; and stratified with respect to season, wind speed and cloud cover. A parame- terization of the diurnal variability is fitted as a function of the variables used to stratify the data, and the coefficients for this fit are also provided with the data. Results are consistent with expectations based on the previous work: the diurnal temperature cycle peaks in early afternoon (circa 2 pm local time); there is an increase in amplitude and a decrease in seasonality towards the equator. Generally, the ocean at this depth cools on windy days and warms on calm days, so that a component of subdaily variability is the SST tendency on slower timescales. By not ‘closing’ the diurnal cycle when stratified by environmental conditions, this dataset differs from previously published diurnal-cycle parameter- izations. This thorough characterization of the SST diurnal cycle will assist in interpreting SST observations made at different local times of day for climatological purposes, and in testing and constraining models of the diurnal-cycle and air-sea interaction at high temporal resolution.

Subjects: Internal Medicine, Humans, Chile, Hospitals, Teaching, Education, Medical, Undergraduate, Hospitals, Private
Abstract: There is a 10 years teaching experience for fourth year medical students and interns in a Chilean private hospital. The students attend an eight weeks practical course. The interns rotate during 16 weeks by specialties and make shifts. The hospital structure with Clinical Services and Medical-Surgical departments facilitates the teaching process. There are approximately 30,000 admissions per year with a mean stay of 3.7 days, that allow the students to be in touch with patients with different diseases that are managed with updated technology. We emphasize the ethical and clinical management of concrete problems of patients, learning and communication skills. The students evaluate their stay answering surveys and with semi structured interviews. Teaching is assessed by tutors and heads of departments, in clinical rounds, sometimes prepared by the students, by a thorough revision of problem oriented medical records and with practical and theoretical tests. The results of the program have been quite satisfactory for participants.

Abstract: In the last few years, several monitoring programs were established as an effect of the EU Directives which included requirements for monitoring the quality of water resources (drinking water, groundwater and surface water). Plant Protection Products (PPPs) are an obvious target for monitoring activities, since they are directly released into the environment. In Italy, the National Environmental Protection Agency (ISPRA) has recently published several reports containing the results of the National Plans for Control of Environmental Effects of PPPs. These documents contain the collection of monitoring data related to the presence of PPP residues in surface and groundwater systems. In this paper, these results (monitoring campaigns from 2005 to 2009) were analysed. Particularly, the attention was focused on the concentration levels of terbuthylazine (TBZ) and its metabolite desethyl-terbuthylazine (DTZ) detected in the groundwater systems of the Lombardia Region (Northern Italy). The analysis allowed us to identify the spatial and temporal trends of contamination of both substances. Furthermore the DTZ/TBZ ratio was calculated in order to recognize point and non-point sources of contamination

39. Heterogeneous p53 mutations in a Burkitt lymphoma from an AIDS patient with monoclonal c-myc and VDJ rearrangements

Abstract: This study investigates the timing of p53 mutations detected in the malignant cells of a Burkitt's lymphoma cell line (BRG-P) with respect to other maturation or transforming events. The BRG-P cell line, derived from an AIDS patient, was of special value since it displayed subclones that had undergone an isotype switch from IgM to IgA1 (BRG-M and BRG-A cells). BRG-M and BRG-A cells were characterized by the same monoclonal c-myc and VDJ rearrangements and by the expression of Ig receptors with specificity for a 45 kDa protein of human breast cells. Analysis of p53 mutations in the different BRG subclones showed that 1) BRG-M cells displayed 2 different p53 mutations in trans; since the original BL cells also showed the same mutations, this finding indicated that both occurred in vivo; 2) one of the p53 alleles of BRG-A cells was lost, while the other showed a mutation different from those seen in BRG-M cells; and 3) all 3 mutations observed in BRG-M or BRG-A cells resulted in the functional inactivation of the transcriptional activation function of p53. Together, our data demonstrate that p53 mutations were relatively late events during lymphomagenesis. Moreover, in view of the role of p53 in cell apoptosis, it is conceivable that BRG cells were subjected to a strong selective pressure that favored p53 inactivation. Such inactivation was possibly required to counterbalance other potentially apoptotic events, including the presence of a deregulated c-myc oncogene and signals delivered by the host environment in situ.
