RESUMO
BACKGROUND: Critically ill patients requiring emergent colectomy have significant mortality risk. OBJECTIVE: A national administrative database was used to compose a simple scoring scheme for predicting in-hospital mortality risk. DESIGN: The 2007 to 2009 Nationwide Inpatient Sample was queried to identify patients requiring nonelective colectomy. Multivariable binary logistic regression analysis was used to identify predictors that increased mortality. Each predictor was given a point value, based on the corresponding logit, the sum of which constituted a risk score. The scoring system was tested by using k-partitions cross-validation. SETTINGS: This study is based on database analysis. PATIENTS: A total of 338,348 cases were identified. Mean age was 64, and 53% of the patients were women. MAIN OUTCOME MEASURES: The primary outcomes measured were mortality and risk score development. RESULTS: The overall mortality risk was 9%. Regression analysis identified the following risk factors and assigned points: acute renal failure (6), hemodialysis (6), age >65 (4), peripheral vascular disease (4), myocardial infarction (4), chronic obstructive pulmonary disease (2), cardiac arrhythmia (1), and congestive heart failure (1). The maximum score observed was 26 (of a possible 28), which corresponded to 100% mortality. Receiver operator characteristic analysis showed an area under the curve of 0.81. LIMITATIONS: This study was limited because of its retrospective nature, and because it used database data with variability in coding among participating institutions. CONCLUSIONS: With the use of a simple 8-variable scoring system, inpatient mortality estimates can be made for patients requiring emergent colectomy. When used judiciously, it can be used as a tool when counseling patients and family both before and after surgery.

PURPOSE: Gastrointestinal tract hemorrhage is a common problem accounting for approximately 1 % of hospital admissions. It is estimated that one third of the episodes of lower gastrointestinal hemorrhage are secondary to diverticular disease. Inter-institutional transfer has been associated with delay in care and increased in-hospital mortality. We hypothesized that patients with diverticular hemorrhage that were transferred from an acute care hospital to tertiary care institutions have increased in-hospital morbidity and mortality when compared to primarily admitted patients. MATERIALS AND METHODS: We performed a retrospective analysis of the Nationwide Inpatient Sample for the year 2008. Patients with a primary discharge diagnosis of diverticular hemorrhage were selected. Multivariate logistic regression was used to identify the relationship between transfer status and in-hospital mortality. RESULTS: A total of 99,415 hospitalizations for diverticular hemorrhage were identified. Transferred patients had higher in-hospital mortality rates compared to primarily admitted patients (3.5 vs. 1.8 %, p < 0.001), as well as increased length of stay (8.4 vs. 5.4 days, p < 0.001) and a higher rate of total abdominal colectomy (1.2 vs. 0.6 %, p < 0.001). Multivariate analysis indicated that transfer status was associated with increased in-hospital mortality [OR 1.8, 95 % CI 1.5-2.8, p < 0.001]. CONCLUSIONS: Inter-institutional transfer for diverticular bleeding is associated with increased in-hospital mortality, increased total abdominal colectomy rate, as well as increased economic burden including mean length of stay and total hospital charges. Further prospective studies are needed to analyze the clinical information of patients requiring transfer to another hospital in order to identify those patients who would truly benefit from inter-institutional transfer.

BACKGROUND: The objective of this study was to analyze a population-based database for (1) recent 9-year trends in utilization of partial cholecystectomy (PC), laparoscopic PC, and trocar cholecystostomy (TC), (2) demographics, associated diagnoses, and hospital characteristics, and (3) relevant inpatient outcomes. METHODS: Retrospective cohort analysis of the Nationwide Inpatient Sample (NIS) files from 2000 to 2008 was performed. For the purposes of the study, gallbladder damage control was defined as PC, laparoscopic PC, and TC. RESULTS: A national estimate of 10,872 gallbladder damage control cases was obtained. Procedures performed included PC (47.8 %), laparoscopic PC (27.2 %), TC (25.3 %), and intraoperative cholangiogram (IOC) (19.7 %). A total of 1,479 (13.6 %) postoperative complications were identified, including pulmonary complications (4.3 %), hemorrhage/hematoma/seroma (3.4 %), and accidental puncture or laceration during procedure (3.3 %). Common bile duct injury occurred in 3.3 % overall. Hospital types included nonteaching (82.1 %) and urban (67.8 %), with regional variations of 42.1 % from the South and 45.2 % from the West. Inpatient outcomes included mean length of stay of 11.4 (0.16 SEM) days, mean total hospital charge of $71,296.69 ($1,106.03 SEM), 7.4 % mortality, and 16.8 % discharge to skilled nursing facility. Multivariate logistic regression analysis identified independent risk variables for common bile duct injury: teaching hospitals (OR = 1.517, CI = 1.155-1.991, P = 0.003). IOC (OR = 2.030, CI = 1.590-2.591, P < 0.001) was a commonly associated procedure in the setting of common bile duct injury. CONCLUSION: Various circumstances may require gallbladder damage control with PC and TC. Postoperative complications and common bile duct injury remain significantly high despite limited resection, and the teaching status of the hospital is associated with CBD injury. High morbidity and mortality of gallbladder damage control may reflect both the compromised nature of the procedures and multiple comorbidities.

Camels are important sources of milk, meat, wool and leather, and are widely used in transportation in arid and semi-arid areas. But their illnesses, especially parasitic diseases, have not been taken into consideration. The Dipetalonema evansi microfilariae are in the blood. Adult nematode is only dedicated to camels and disrupts spermatic arteries, lung arteries, right atrium, and testicles. This study was carried out on testicular samples of camels infected with D. evansi referred from slaughterhouse. In each of the control and contaminated groups, 5 samples were examined. In this study, in addition to the qualitative description of parasite histopathologic lesions, the spermatogenesis process was evaluated quantitatively including spermatogenesis process, diameter of the seminiferous tubules and Johnsen ranking and compared with the control group. Histopathological examination of infected testis with D. evansi showed lumen obstruction of testicular blood vessels by parasites, hypertrophy of blood vessels, degenerative and necrosis changes in the tubules, decreased spermatogenetic activity, increased interstitial space tubules, destruction of the spermatogenic cells. Also, there was a significant difference in the control and contaminated groups in the parameters of spermatogenesis, diameter of the seminiferous tubules and Johnsen score.
RESUMO
OBJECTIVES: Wound healing is a complex and dynamic process that begins immediately following tissue injury and continues until the wound is completely healed and remodeled. Applying the most effective burn repair techniques is a constant challenge in medicine. Antiulcerogenic and wound healing properties of Areca palm leaves have been validated through various investigations and animal studies. This study aimed to determine the potential for A. palm hydroalcoholic extract to heal burn wounds in rats. MATERIALS AND METHODS: For 14 days, we examined 40 male Wistar albino rats in 5 groups: those receiving 1% silver sulfadiazine cream (reference standard), those receiving eucerin (positive control), and those receiving 5% and 10% ointments of Areca catechu hydroalcoholic extract (treatment groups). No treatment was given to the negative control group. On the dorsal part of the animals' necks, burn wounds were made. After the rats were sacrificed, the wound contraction rate (WCR) was determined, and the wound sites were histopathologically examined. RESULTS: On the 14th day, the WCR was significantly higher in rats treated with A. palm 10% extract ointment than in rats treated with 5% extract, positive or negative control groups (p < 0.001), or rats treated with silver sulphfadiazine (p = 0.01). After applying a 10% extract ointment to burn wound sites, complete healing occurred with only mild tissue inflammation and edema. CONCLUSION: The study's findings indicate that the hydroalcoholic extract of A. palm L. has the ability to expedite the wound healing process. Additional research is necessary to identify the compounds responsible for their wound healing properties and comprehend their action mechanism.
RESUMO
To study the effectiveness of pomegranate juice on osteoarthritis, mono-iodoacetate induced loss of articular cartilage in the mouse tibiofemoral joint was used as a model. Mono-iodoacetate is an inhibitor of glycolysis which promotes osteoarthritis similar to that noted in human osteoarthritis. The histopathology of the subchondral bone and cartilage of mouse knee joints treated with a single intra-articular injection of mono-iodoacetate (0.1 mg) and killed at 1, 14 and 28 days post injection was investigated. The effect of pomegranate juice (4 mL/kg, 10 mL/kg, 20 mL/kg, orally) was studied in different groups. Histopathological changes in knee joints were seen after 2 weeks. Early osteoarthritis was characterized by areas of chondrocyte degeneration, which sometimes involved the entire thickness of the articular cartilage in the tibial plateaus and femoral condyles. Changes to the subchondral bone and proteoglycan contents, focal fragmentation and collapse of bony trabeculae with fibrosis and necrosis, and synovial cell proliferation were observed. The administration of pomegranate juice dose dependently prevented the negative effects of iodoacetate. Chondrocyte damage was significantly prevented, with proteoglycan less affected, especially in the groups receiving a high amount of pomegranate juice. No cell proliferation or inflammatory cells were detected in the synovial fluid. The effectiveness of pomegranate juice in improving histopathological damage is emphasized and its chondroprotective effect in vivo highlighted.

BACKGROUND: In this study, we used a single-institution database to examine the risks of heart transplantation in patients with diabetes mellitus (DM). METHODS: Recipients 18 years and older who underwent cardiac transplantation from July 1994 to December 2000 were reviewed; 101 consecutive patients with insulin-dependent diabetes mellitus and non-insulin-dependent diabetes mellitus were compared with 244 patients who did not have DM and who received standard donor hearts. Survival, renal function (serum creatinine concentration), development of transplant coronary artery disease (TCAD), severe rejection, and infection (requiring hospitalization) were analyzed. RESULTS: Patients with DM were older (mean age, 57.1 years vs 51.4 years), had greater body mass index (mean, 26.7 vs 24.1 kg/m(2), p < 0.02), and more commonly had ischemic cardiomyopathy (58% vs 43%, p = 0.02). We found a trend toward decreased survival for those with DM at 1 year (85.1% vs 90.9%; p = 0.12). Five-year survival was 81.6% for both groups. Mean follow-up time was 4.1 years. Infection rate within 3 months was greater among those with DM (14% vs 3%, odds ration = 5.09; 95% confidence interval, 1.59-16.23). Freedom from infection at 4 years was 71.0% for patients with DM and 85.0% for those without DM (p = 0.02). Freedom from rejection at 4 years was similar (70.6% vs 73.6%, p = 0.69). At 4 years, transplant coronary artery disease (TCAD)-free survival was 69.5% for those with DM and 81.6% for those without (p = 0.23). Mean serum creatinine concentration at 4 years after transplant was 1.5 mg/dl in patients with DM (vs 1.4, p = 0.28). Multivariate analysis showed increased baseline creatinine level as a significant risk factor for survival and showed pre-transplant ischemic cardiomyopathy as a risk factor for TCAD in both groups. Body mass index >30 was a significant risk factor for survival among patients with DM. CONCLUSION: We found an increased risk of serious infections in patients with DM, particularly in the early post-operative period. Careful consideration of obesity and renal function during evaluation of candidacy is indicated.

BACKGROUND: Donor atraumatic intracranial bleed (aICB) is associated with older age and may reflect a history of hypertension. Hearts from donors who died of aICB may be at increased risk for graft failure because of the associated catecholamine surge. We evaluated whether receiving a heart from a donor who had an aICB independently affected the outcome of transplantation. METHODS: We reviewed adult patients (>18 years) who underwent heart transplantation between July 1994 and December 1999. We excluded patients who received non-standard hearts (e.g., donor age >55 years). Group 1 received hearts from donors with aICB (n = 80), and Group 2 received hearts from donors who did not have aICB (n = 171). RESULTS: Recipient age, gender, United Network for Organ Sharing status, and indication for transplantation were similar for both groups. Donors in Group 1 were older (41 vs 26 years, p = 0.001), more commonly women (55% vs 20%, p = 0.001), and more often had history of hypertension (26% vs 2%, p = 0.001). Survival to discharge was 86% in Group 1 and 95% in Group 2. Actuarial 5-year survival was 72% for Group 1 and 81% for Group 2 (p = 0.52). Regression analysis showed that receiving a heart from a donor with aICB was a risk factor for early recipient mortality but not for long-term outcome (odds ratio = 3.25, p = 0.02, and hazard ratio = 1.16, p = 0.69, respectively). Donor aICB, female gender, and abnormal initial echocardiogram (global hypokinesia) were selected as clinically relevant independent risk factors for early mortality of the recipient, using a fitted multifactor logistic regression model (goodness-of-fit chi-square p value = 0.94). Donor age, accident-to-retrieval time interval, and borderline left ventricular hypertrophy did not significantly differ. Five-year freedom from transplant coronary artery disease in Group 1 was 74% (vs 80% in Group 2, p = 0.05). CONCLUSIONS: The trend observed in this series suggests that receiving a heart from a donor with aICB is a potential independent risk factor for early mortality after transplantation independent of age. Caution should be used when evaluating such donors, particularly when other risk factors such as female donor or depressed ejection fraction are present.

Giant-cell myocarditis is a rare and aggressive form of myocarditis with a high mortality rate. Our purpose is to summarize 3 cases of acute giant-cell myocarditis that illustrate possible outcomes with mechanical support. We reviewed the cases of 3 patients, aged 39 to 59 years, who had giant-cell myocarditis (confirmed by myocardial biopsy). The indication for ventricular assist was circulatory failure despite maximal medical treatment with 2 or more inotropic agents and intraaortic balloon pump support. Immunosuppression and a biventricular mechanical assist (BVS 5000) were used to treat all these patients. The mean duration of mechanical support was 15.7 days (range, 10 to 19 days). One patient had recovery of myocardial function and was weaned from mechanical support. This case is, to our knowledge, the first reported of ventricular support leading to cardiac recovery after diagnosis of giant-cell myocarditis. The 2nd patient was not a candidate for further surgery and died of multisystem organ failure. The 3rd patient underwent orthotopic heart transplantation after 18 days of support and was discharged. We conclude that patients with giant-cell myocarditis tend to have biventricular involvement and can recover myocardial function on mechanical support and immunosuppression. If recovery is not observed, transplantation is warranted. By avoiding left ventricular cannulation, the BVS 5000 is well suited for bridging to recovery, transplantation, or long-term support.

IMPORTANCE: This study analyzes a role of laparoscopy in obese patients with ventral hernia. OBJECTIVE: To evaluate the outcomes of laparoscopic compared with open ventral hernia repair (VHR) in obese patients. DESIGN: Retrospective cohort analysis. SETTING: Nationwide hospital survey. PARTICIPANTS: Obese patients undergoing VHR from 2008 through 2009 were selected from the Nationwide Inpatient Sample database. MAIN OUTCOMES AND MEASURES: Data analysis included intraoperative and postoperative complications, length of stay, and total hospital charges. Additional patient demographics, including insurance, median income, and locations, were analyzed. RESULTS: Of the 47,661 obese patients who underwent VHR during the study period, laparoscopic VHR increased more than 4-fold, from 1547 of 23,917 (6.5%) to 6629 of 23,704 (28.0%) (P < .001). Laparoscopic VHR was associated with a lower overall complication rate (6.3% vs 13.7%; P < .001), shorter median length of stay (3 vs 4 days; P < .001), and lower mean total hospital charges ($40,387 vs $48,513; P < .001). Multivariable logistic regression analysis identified a predictive variable for laparoscopic VHR: private insurance (odds ratio, 1.20; 95% CI, 1.15-1.27; P < .001). Ventral hernias with a gangrenous bowel were less likely to undergo laparoscopic VHR (odds ratio, 0.14; 95% CI, 0.06-0.34; P < .001). CONCLUSIONS AND RELEVANCE: In the era of laparoscopy, the overall use of laparoscopic VHR in obese patients has increased significantly and appears to be safe, with a shorter stay and a lower cost of care.

BACKGROUND: To assess the incidence of cervical spine (C-spine) injuries in patients admitted after motorcycle crash in states with mandatory helmet laws (MHL) compared with states without helmet laws or selective helmet laws. METHODS: The Nationwide Inpatient Sample from the Healthcare and Utilization Project for the year 2008 was analyzed. International Classification of Diseases and Health Related Problems, Ninth Edition codes were used to identify patients with a diagnosis of motorcycle crash and C-spine injuries. National estimates were generated based on weighted analysis of the data. Outcome variables investigated were as follows: length of stay (LOS), in-hospital mortality, hospital teaching status, and discharge disposition. States were then stratified into states with MHL or selective helmet laws. RESULTS: A total of 30,117 discharges were identified. Of these, 2,041 (6.7%) patients had a C-spine injury. Patients in MHL states had a lower incidence of C-spine injuries (5.6 vs. 6.4%; p = 0.003) and less in-hospital mortality (1.8 vs. 2.6%; p = 0.0001). Patients older than 55 years were less likely to be discharged home (57.5% vs. 72.5%; p = 0.0001), more likely to die in-hospital (3.0% vs. 2.1%; p = 0.0001), and more likely to have a hospital LOS more than 21 days (7.7% vs. 6.2%; p = 0.0001). CONCLUSION: Patients admitted to the hospital in states with MHLs have decreased rate of C-spine injuries than those patients admitted in states with more flexible helmet laws. Patients older than 55 years are more likely to die in the hospital, have a prolonged LOS, and require services after discharge. LEVEL OF EVIDENCE: III.

BACKGROUND: Heart transplantation in the elderly is increasingly common. In the mid-1990s, 25% of recipients in our program were >62 years of age. We evaluated outcomes from one institution with the hypothesis that older recipients may be at higher risk of major complications associated with immunosuppression. METHODS: We analyzed results for 182 patients aged 62 to 75 years (mean +/- SD: 66.3 +/- 11.4 years) who underwent heart transplantation between January 1995 and July 2001 at a single institution. They were compared with a control group of 348 contemporaneous adult recipients aged 18 to 62 years (mean +/- SD: 48.2 +/- 11.4 years). All recipients in this consecutive cohort had a follow-up of at least at least 5 years. End-points studied were Kaplan-Meier survival, freedom from dialysis and freedom from malignancy at 100 months. Follow-up was 100% at 100 months. RESULTS: At 100 months, survival for the elderly was 55% (46 remaining at risk) and 63% (102 remaining at risk) for controls (p = 0.051, log-rank test). Re-transplant and dialysis, but not recipient age or malignancy, were predictive of survival by regression analysis (p = 0.003, p < 0.001, p = 0.53 and p = 0.84, respectively). Freedom from malignancy at 100 months was 68% for the elderly and 95% for controls (p < 0.001). Age predicted malignancy by regression analysis (p < 0.001). At 100 months, freedom from dialysis was 81% for the elderly and 87% for controls (p = 0.005). Pre-operative creatinine, but not age, was predictive of need for dialysis (p = 0.003 and p = 0.47, respectively). CONCLUSIONS: Although long-term survival of older heart transplant recipients is acceptable, it is significantly lower than in young recipients. The increased risk of renal failure and malignancy among elderly patients likely influences the difference in survival observed between the two groups. Pre-operative renal function warrants careful consideration. As ventricular assist device technology improves, it may be used to complement heart transplantation to avoid immunosuppression and its side effect of malignancy in older patients with advanced heart failure.

OBJECTIVE: To compare the different diagnostic criteria for gestational diabetes mellitus (GDM) proposed by the American Diabetes Association (ADA), World Health Organization (WHO), and Australian Diabetes in Pregnancy Society (ADIPS) in a 75-g, 2-hour oral glucose tolerance test (OGTT) and to investigate their effects on neonatal birth weight. METHODS: Healthy pregnant women were enrolled in a cohort study to undergo a 75-g OGTT during 24 to 28 weeks of pregnancy and then followed up to delivery. ADA criteria and recommendations were used for the management of patients. RESULTS: Among 670 pregnant women, GDM was diagnosed in 41 (6.1%), 81 (12.1%), and 126 (18.8%) on the basis of ADA, WHO, and ADIPS criteria, respectively. The kappa value was 0.38 (P<.0001) for the agreement between ADA and WHO criteria, 0.41 (P<.0001) for agreement between ADA and ADIPS criteria, and 0.64 (P<.0001) for agreement between WHO and ADIPS criteria. WHO-only "positive" women had significantly lower fasting plasma glucose (87.9 versus 102.2 mg/dL; P<.0001) and 1-hour plasma glucose levels (146.4 versus 200.5 mg/dL; P<.0001) but higher 2-hour plasma glucose levels (150.1 versus 109.1 mg/dL; P<.0001) than women diagnosed with GDM by only ADA criteria. The correlation coefficient between 1-hour glucose level and neonatal birth weight was 0.09 (P<.02). The adjusted odds ratio of macrosomia associated with GDM according to ADA criteria was 1.34 (95% confidence interval, 0.15 to 12). CONCLUSION: The frequency of occurrence of GDM was 6.1% in a 75-g OGTT based on ADA criteria, and there was fair agreement between ADA and WHO criteria, moderate agreement between ADA and ADIPS criteria, and strong agreement between WHO and ADIPS criteria. A modest correlation was found between the 1-hour serum glucose value and neonatal birth weight.

Older age, prior transplantation, pulmonary hypertension, and mechanical support are commonly seen in current potential cardiac transplant recipients. Transplants in 436 consecutive adult patients from 1994 to 1999 were reviewed. There were 251 using standard donors in 243 patients (age range 18-69 years). To emphasize recipient risk, 185 patients who received a nonstandard donor were excluded from analysis. The indications for transplant were ischemic heart disease (n = 123, 47%), dilated cardiomyopathy (n = 82, 32%), and others (n=56, 21%). One hundred and forty-nine (57%) recipients were listed as status I; 5 and 6% were supported with an intra-aortic balloon and an assist device, respectively. The 30-d survival and survival to discharge were 94.7 and 92.7%, respectively; 1-year survival was 89.1%. Causes of early death were graft failure (n = 6), infection (n = 4), stroke (n = 4), multiorgan failure (n = 3) and rejection (n = 2). Predictors were balloon pump use alone (OR= 11.4, p =0.002), pulmonary vascular resistance > 4 Wood units (OR = 5.7, p = 0.007), pretransplant creatinine > 2.0 mg/dL (OR = 6.9, p = 0.004) and female donor (OR = 8.3, p = 0.002). Recipient age and previous surgery did not affect short-term survival. Heart transplantation in the current era consistently offers excellent early and 1-year survival for well-selected recipients receiving standard donors. Early mortality tends to reflect graft failure while hospital mortality may be more indicative of recipient selection.
