    Introduction Elevated serum levels of S100β, an astrocyte-derived protein, correlate with unfavourable neurological outcomes following cardiac surgery, neurotrauma, and resuscitation. This study evaluated whether pre-/postoperative serum S100β levels correlate with unfavourable clinical and radiological findings in patients undergoing elective meningioma resection. Methods In 52 consecutive patients admitted for meningioma surgery, serum S100β levels were determined upon admission and immediately, 24 hours, and 48 hours after surgery. All patients underwent complete pre- and postoperative neurological examination and mini-mental state examination. Radiological evaluation included preoperative magnetic resonance imaging (MRI) and postoperative computed tomography. Tumour volume, brain edema, and bleeding volume were calculated using BrainSCAN™ software. Results Preoperative S100β levels did not correlate with the tumour characteristics demonstrated by preoperative MRI (for example, tumour volume, edema volume, ventricular asymmetry, and/or midline shift). Preoperative serum S100β levels (0.065 ± 0.040 μg/l) were significantly lower than the levels measured immediately (0.138 ± 0.081 μg/l), 24 hours (0.142 ± 0.084 μg/l), and 48 hours (0.155 ± 0.119 μg/l) postoperatively (p < 0.0001). Significantly greater postcraniotomy S100β levels were observed with prolonged surgery (p = 0.039), deterioration in the mini-mental state examination (p = 0.005, 0.011, and 0.036 for pre versus immediate, 24 hours, and 48 hours postsurgery, respectively), and with postoperative brain computed tomography evidence of brain injury; bleeding was associated with higher serum S100β levels at 24 and 48 hours after surgery (p = 0.046, 95% confidence interval [CI] -0.095 to -0.001 and p = 0.034, 95% CI -0.142 to -0.006, respectively) as was the presence of midline shift (p = 0.005, 95% CI -0.136 to -0.025 and p = 0.006, 95% CI -0.186 to -0.032, respectively).

    Background Circulating biomarkers can predict clinical outcomes in colorectal cancer patients. The aim of the study was to evaluate the feasibility of our multigene biomarker chip for detecting circulating tumor cells for postoperative surveillance of stage I–III colorectal cancer patients. Materials and Methods In total, 298 stage I–III colorectal cancer patients were analyzed after curative resection between June 2010 and October 2014. During each follow-up, a postoperative surveillance strategy, including ESMO Guidelines Working Group recommendations and the biochip, was used. Results After a 28.4-month median follow-up, 48 (16.1%) patients had postoperative relapse. Univariate analysis revealed that the postoperative relapse risk factors were rectal tumor, perineural invasion, elevated preoperative and postoperative serum carcinoembryonic antigen levels, and positive biochip results (all P < 0.05). Multivariate analyses revealed that postoperative relapse correlated significantly with elevated postoperative serum carcinoembryonic antigen levels (odds ratio = 4.136, P = 0.008) and positive biochip results (odds ratio = 66.878, P < 0.001). However, the sensitivity (P = 0.003), specificity (P = 0.003), positive (P = 0.002) and negative (P = 0.006) predictive values, and accuracy (P < 0.001) of the biochip for predicting postoperative relapse were significantly higher than those of elevated postoperative serum carcinoembryonic antigen levels. Moreover, the median lead time between positive biochip result and postoperative relapse detection was significantly earlier than that between elevated postoperative serum carcinoembryonic antigen level and postoperative relapse detection (10.7 vs. 2.8 months, P < 0.001). Furthermore, positive biochip results correlated strongly with lower disease-free survival and overall survival of colorectal cancer patients (both P < 0.001). Conclusion Compared with conventional serum carcinoembryonic antigen detection, our multigene

    Introduction Several studies have shown that lactoferrin (LF) and neopterin (NT) are correlated with infection. The aim of this study is to determine whether serum levels of LF and NT are associated with postoperative infectious complications in patients with acute traumatic spinal cord injury. Material and methods A total of 268 patients with acute traumatic spinal cord injury who underwent spinal surgery were enrolled in this study. Serum levels of LF, NT, and C-reactive protein (CRP), in addition to white blood cell count (WBC) and erythrocyte sedimentation rate (ESR), were measured preoperatively and 24 h postoperatively. Results In total, 22 of 268 patients (8.2%) developed postoperative infectious complications. The levels of serum LF, NT, and CRP were significantly higher in the infected patients than in the non-infected patients. No significant differences were observed in postoperative WBC count and ESR between the two groups. Multivariate logistic regression revealed that LF (OR: 1.004 (1.002–1.007)), NT (OR: 1.137 (1.054–1.227)), and CRP (OR: 1.023 (1.002–1.044)) were significantly associated with the presence of postoperative infectious complications. The area under receiver operating characteristic curves for LF, NT, and CRP was 0.709, 0.779, and 0.629, respectively. Conclusions Elevated serum concentrations of LF and NT are associated with early infection after surgery. Compared to CRP, elevated levels of LF and NT are better indicators for predicting postoperative infectious complications in patients with acute traumatic spinal cord injury. PMID:24273571

    We examined esophageal cancer patients who received enteral nutrition (EN) to evaluate the validity of early EN compared to delayed EN, and to determine the appropriate time to start EN. A total of 208 esophagectomy patients who received EN postoperatively were divided into three groups (Group 1, 2 and 3) based on whether they received EN within 48 h, 48 h-72 h or more than 72 h, respectively. The postoperative complications, length of hospital stay (LOH), days for first fecal passage, cost of hospitalization, and the difference in serum albumin values between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test, the Mann-Whitney U test and the chi square test. Statistical significance was defined as p < 0.05. Group 1 had the lowest thoracic drainage volume, the earliest first fecal passage, and the lowest LOH and hospitalization expenses of the three groups. The incidence of pneumonia was by far the highest in Group 3 (p = 0.019). Finally, all the postoperative outcomes of nutritional conditions were the worst by a significant margin in Group 3. It is therefore safe and valid to start early enteral nutrition within 48 h for postoperative esophageal cancer patients.

    A prospective evaluation of In-111 labeled autologous platelet scintigraphy for the early diagnosis of acute postoperative renal transplant rejection was undertaken. To date, 28 consecutive patients between 7 and 14 days post-op have been injected with 500..mu..Ci of In-111 platelets followed by imaging at 24 and 48 hours. Activity within the renal transplant exceeding activity in the adjacent iliac vessels was considered to be evidence of rejection, and both chemical evidence and clinical impression of rejection at 5 days after completion of imaging was accepted as proof of ongoing or incipient rejection at the time of scintigraphy. In addition, to visual inspection, independent quantitative analysis compared the area-normalized activity over the transplant with the adjacent iliac vessels (normal <1.0). For 5 patients, positive In-111 scintigraphy was present before convincing clinical evidence of rejection. In-111 platelet scintigraphy is useful not only to confirm the clinical diagnosis of rejection but also to establish the early, pre-clinical diagnosis of incipient acute postoperative renal transplant rejection.

    Abstract The factors, determining possibility of early postoperative morbidity occurrence in patients, suffering gastro-esophageal zone cancer, were analyzed. After radical operation performance (gastrectomy, gastric and esophageal resection) 5.7% patients died. Insufficience of the anastomosis sutures with peritonitis occurrence, an acute hepato-renal insufficience, an acute coronary syndrome, pulmonary thromboembolism, pneumonia, the brain insult, pancreonecrosis and mesenterial thrombosis constituted the main morbidities. The complications occurrence depends upon the tumoral process course severity, morphological variant of cancer, presence of concomitant diaphragmatic hernia and the blood rheological properties. Initially high indices of the blood sera present a rheological properties of blood serum may serve as a prognostic criterion of the postoperative complications occurrence in the patients.

    The effects of early postoperative radiation were assessed in free nonvascularized and free vascularized rib grafts in the canine model. The mandibles of one-half of the dogs were exposed to a cobalt 60 radiation dose of 4080 cGy over a 4-week period, starting 2 weeks postoperatively. The patency of vascularized grafts was confirmed with bone scintigraphy. Histological studies, including ultraviolet microscopy with trifluorochrome labeling, and histomorphometric analyses were performed. Osteocytes persist within the cortex of the vascularized nonradiated grafts to a much greater extent than in nonvascularized, nonradiated grafts. Cortical osteocytes do not persist in either vascularized or nonvascularized grafts subjected to radiation. New bone formation is significantly retarded in radiated grafts compared with nonradiated grafts. Periosteum and endosteum remained viable in the radiated vascularized grafts, producing both bone union and increased bone turnover, neither of which were evident to any significant extent in nonvascularized grafts. Bone union was achieved in vascularized and non-vascularized nonradiated bone. In the radiated group of dogs, union was only seen in the vascularized bone grafts.

    ABSTRACT Background: Roux-en-Y gastric bypass is one of the most common bariatric surgery and leads to considerable weight loss in the first months. Aim: To quantify the main early postoperative complications in patients submitted to the gastric bypass. Method: Observational retrospective cohort. Data of 1051 patients with class II obesity associated with comorbidities or class III obesity submitted to the gastric bypass with 30 days of follow-up starting from the date of the surgery. Results: The age average was 36 years with a predominance of females (81.1%). The mean preoperative body mass index was 43 kg/m². The major complication was fistula (2.3%), followed by intestinal obstruction (0.5%) and pulmonary embolism (0.5%). Death occurred in 0.6% of the cases. Conclusion: In the period of 30 days after surgery the overall complication rate was 3.8%; reoperation was necessary in 2.6% and death occurred in 0.6%. Fistula was the main complication and the leading cause of hospitalization in intensive care unit, reoperation and death. PMID:27683781

    Serum gastrin concentration was measured in newborns and infants with no gastrointestinal disorders, in the fasting state and after food stimulation. Mean fasting concentration in 14 newborns aged 1 to 12 days (130 . 4 pg/ml +/- 11 . 4 SE) was significantly higher than the mean value in 23 infants aged 1.5 to 22 months (101.4 +/- 6.6 pg/ml). Ingestion of the usual milk meal resulted in a definite rise of the serum gastrin level in the 5 subjects tested (3 newborns and 2 infants). The mean fasting serum gastrin level in 6 babies with hiatus hernia and gastro-oesophageal reflux was found to be no different from the corresponding value in 8 age-matched controls. However, a conspicuously raised fasting gastrin concentration was observed in one infant with lower oesophageal dyskinesia. The results indicate that the release of gastrin and the reactivity of the hormone-producing sites to food stimulation in early life are similar to those in adult humans. No defect of gastrin release was shown in patients with gastro-oesophageal reflux. PMID:1244175

    Objective To correlate serum level of monocyte chemoattractant protein-1 (MCP-1) with postoperative recurrence of spinal tuberculosis in the Chinese Han population. Methods Patients of Han nationality with newly diagnosed spinal tuberculosis were consecutively included in this study. At different time points postoperatively, serum level of MCP-1 was determined using an enzyme linked immunosorbent assay. Recurrence of spinal tuberculosis after surgery and during the follow-up period was recorded. The correlation between serum MCP-1 level and recurrence of spinal tuberculosis was analyzed. Results A total of 169 patients with spinal tuberculosis were included in the study and followed up for an average of2.2±1.3 years (range, 1–5 years). Of these patients, 11 had postoperative recurrence of spinal tuberculosis. The patients’ serum level of MCP-1 increased significantly after postoperative recurrence of spinal tuberculosis. Once the symptoms of recurrence were cured, the serum level of MCP-1 decreased significantly and it did not differ from patients without disease recurrence. Conclusion Postoperative recurrence of spinal tuberculosis is likely to increase the serum level of MCP-1. PMID:25962150

    31 children aged 1 to 9 years with malformations of the kidneys and upper urinary tracts were preoperatively examined for immune status. After plastic operation 14 children developed early postoperative infectious-inflammatory complications. It is suggested that early postoperative complications in some children with renal and upper urinary tract maldevelopments may arise because of weak compensatory abilities and immunodeficiency resultant from the operative stress. These created favourable conditions for activation of latent infection. Immunological assessment of the patient prior to surgery predicts early postoperative complications and thus enables proper preventive measures.

    Abstract Persistence of postoperative radicular pain after surgery for multifocal disc herniation (MFDH) is a clinical problem. This study aims to evaluate the effects of a combined treatment approach compared with unilateral stabilization on early postoperative radicular pain in patients with MFDH. Age, sex, level of operation, clinical findings, and radicular pain visual analogue scale (VAS) scores before surgery in the early postoperative period and at 3 months after surgery were retrospectively reviewed for 20 cases of multifocal lumbar disc herniation. The combined approach (translaminar and far lateral) was used for 13 cases. Seven cases underwent transforaminal lumbar interbody fusion (TLIF) and unilateral transpedicular stabilization following total facetectomy. The mean age of the sample was 49.4 ± 10.1 years and the female-to-male ratio was 8:12. The mean VAS scores for radicular pain in cases treated with the combined approach were 8.2, 4.07, and 2.3 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean score for radicular pain improved by 50.4% in the early postoperative period and by 72% in the late postoperative period. The mean VAS scores for radicular pain in cases who underwent TLIF and unilateral stabilization after facetectomy were 8.4, 2.1, and 1.4 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean VAS score for radicular pain improved by 75% in the early postoperative period and by 83.3% in the late postoperative period. The combined approach is an effective alternative in cases with MFDH. TLIF and unilateral segmental stabilization provide substantial decompression and eliminate mechanical compression by conserving the height of the intervertebral foramen in the event that sufficient decompression is unable to obtain. We suggest that elimination of chemical mediators, particularly those causing pain in the dorsal ganglion, contributes to

    AIM To investigate serum urokinase-type plasminogen activator receptor (uPAR) and liver stiffness in biliary atresia (BA) and examine the correlation of circulating uPAR, liver stiffness, and clinical outcomes in postoperative BA children. METHODS Eighty-five postKasai BA children and 24 control subjects were registered. Circulating uPAR was measured using enzyme-linked immunosorbent essay. Liver stiffness was analyzed using transient elastography. RESULTS BA children had significantly greater circulating uPAR and liver stiffness scores than control subjects (P < 0.001). Circulating uPAR and liver stiffness were substantially higher in jaundiced BA children than non-jaundiced BA children (P < 0.001). In addition, circulating uPAR was positively associated with serum aspartate aminotransferase (r = 0.507, P < 0.001), alanine aminotransferase (r = 0.364, P < 0.001), total bilirubin (r = 0.559, P < 0.001), alkaline phosphatase (r = 0.325, P < 0.001), and liver stiffness scores (r = 0.508, P < 0.001). CONCLUSION Circulating uPAR and liver stiffness values were greater in BA children than healthy controls. The increased circulating uPAR was associated with liver dysfunction in BA. As a consequence, serum uPAR and liver stiffness may be used as noninvasive biomarkers indicating the progression of liver fibrosis in postKasai BA. PMID:27957246

    Introduction Acute renal dysfunction is a common complication of cardiac surgery. Furosemide is used in prevention, or treatment, of acute renal dysfunction. This study was conducted to evaluate the protective effects of intra- and early postoperative furosemide infusion on preventing acute renal dysfunction in elective adult cardiac surgery. Methods Eighty-one patients, candidates of elective cardiac surgery, were enrolled in this study in either the furosemide (n=41) or placebo (n=40) group. Furosemide (2 mg/h) or 0.9% saline was administered and continued up to 12 hours postoperatively. We measured serum creatinine (Scr) at preoperative and on the second and fifth postoperative days. Then calculated estimated glomerular filtration rate (eGFR) at these times. An increase in Scr of >0.5 mg/dL and/or >25%–50%, compared to preoperative values, was considered as acute kidney injury (AKI). In contrast, an increase in Scr by >50% and/or the need for hemodialysis was regarded as acute renal failure (ARF). At the end we compared the AKI or ARF incidence between the two groups. Results On the second and fifth postoperative days, Scr was lower, and the eGFR was higher in the furosemide group. AKI incidence was similar in the two groups (11 vs 12 cases; P-value 0.622); however, ARF rate was lower in furosemide group (1 vs 6 cases; P-value 0.044). During the study period, Scr was more stable in the furosemide group, however in the placebo group, Scr initially increased and then decreased to its preoperative value after a few days. Conclusion This study showed that intra- and early postoperative furosemide infusion has a renal protective effect in adult cardiac surgery with cardiopulmonary bypass. Although this protective effect cannot be discovered in mild renal dysfunctions, it apparently reduces the rate of the more severe renal dysfunctions. A more multidisciplinary strategy may be needed in reducing the milder renal damage. PMID:28176949

    The beneficial effects of dexmedetomidine (DEX) have not been extensively investigated in elderly patients receiving spinal anesthesia. This study evaluated the effects of intravenous DEX infusion on stress and hemodynamic response, as well as on postoperative analgesia in elderly patients undergoing total knee arthroplasty (TKA). We randomly allocated 45 adult patients to 3 patient groups (n=15 each): uni-saline group patients underwent unilateral TKA with saline administration, uni-DEX group patients underwent unilateral TKA with DEX administration, and bilateral-DEX group patients underwent bilateral TKA with DEX administration. Serum interleukin-6 (IL-6) levels were significantly lower in the bilateral-DEX group than in the uni-saline group 6 and 24h postoperatively, and were negatively correlated with total DEX dosage 24h postoperatively. Bradycardia occurred more frequently in the uni-DEX and bilateral-DEX groups than in the uni-saline group. The total dose of required supplementary analgesics was significantly higher in the uni-saline group than in the uni-DEX and bilateral-DEX groups 6h postoperatively. The results indicate that perioperative intravenous DEX administration decreases postoperative serum IL-6 levels in patients undergoing bilateral TKA, and has a postoperative analgesic effect in patients undergoing unilateral or bilateral TKA.

    The structure and causes of postoperative complications occurrence, necessitating early relaparotomy conduction through last 5 yrs and 30 yrs ago, were analyzed. The complications rate almost did not change, but their structure--essentially. The occurrence rate for eventration, adhesive ileus, relaparotomy performance for abdominal cavity abscess have had lowered significantly due to introduction of a new operative technologies and prophylactic measures. The lowering of lethality after relaparotomy is caused by improvement of the complications diagnosis, timely performance of reoperations, application of laparostomy in the treatment of postoperative peritonitis, what have permitted to govern a postoperative period course.

    Orthotopic liver transplantation (OLT) is the only curative treatment for end-stage liver disease. Early diagnosis and treatment of infections after OLT are usually associated with improved outcomes. This study's objective is to identify reliable factors that can predict postoperative infectious morbidity. 27 children were included in the analysis. They underwent liver transplantation in our department. The correlation between two parameters (the level of blood glucose at 5th postoperative day and the duration of the anhepatic phase) and postoperative infections was analyzed, using univariate analysis. In this analysis, an independent predictive factor was derived which adequately identifies patients at risk of infectious complications after a liver transplantation.

    It is well established that the nutritional state greatly influences tolerance during the operation. Authors present a new procedure for the early postoperative enteral alimentation having not been used in Hungary so far. Twelve hours after operation, a pump-operated, gradually increasing amount of oligopeptide food-preparation and concentrate is introduced continuously into the second jejunal loop intraoperatively. Using this method, a caloric intake of 9572 kJ can be achieved already from the fourth postoperative day onwards. Based on our experience gained from 32 patients, the method can be recommended for an up-to-date postoperative enteral alimentation.

    Background This study aimed to determine early postoperative changes of plasma polyunsaturated fatty acids (PUFAs) following laparoscopic sleeve gastrectomy (LSG). Methods Ten obese patients (mean BMI: 51.10 ± 11.59 kg/m2) underwent LSG and eleven normal weight control patients (mean BMI: 24.37 ± 2.33 kg/m2) underwent laparoscopic abdominal surgery. Fasting blood samples were collected prior to surgery, at day 1 after surgery and after postoperation oral feeding. Plasma levels of arachidonic acid (AA, C20:4n6), dihomo-gamma-linolenic acid (DGLA, C20:3n6), eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6n3) were determined by an optimized multiple reaction monitoring (MRM) method using ultra fast-liquid chromatography (UFLC) coupled with tandem mass spectrometry (MS/MS). Prostaglandin E2 (PGE2) was measured in serum samples by enzyme immunoassay. Results A significant decrease was observed in insulin and HOMA IR levels in sleeve gastrectomy patients after postoperation oral feeding compared to preoperation. Plasma AA levels and AA/EPA ratio were significantly increased in sleeve gastrectomy patients after postoperation oral feeding compared to postoperation day 1. Serum PGE2 levels and AA/DHA ratio was significantly higher in sleeve gastrectomy patients at preoperation, postoperation day 1 and after postoperation oral feeding when compared to control group patients. Conclusion Increased peripheral insulin sensitivity associated with LSG may play a role in the significant increase of plasma AA levels in sleeve gastrectomy patients following postoperation oral feeding. The significant increase in PGE2 levels and AA/DHA ratio in sleeve gastrectomy group patients also confirms the presence of a proinflammatory state in obesity. PMID:24694037

    Postoperative cognitive dysfunction (POCD) is a frequent complication following major surgery in the elderly. However, the exact pathogenic mechanisms are still unknown. Dexmedetomidine, a selective alpha 2 adrenal receptor agonist, was revealed anesthesia and brain protective role. The present study aimed to examine whether dexmedetomdine protects against POCD induced by major surgical trauma under general anesthesia in aged mice. In the present study, cognitive function was assessed by Y-maze. Proinflammatory cytokines interleukin-1β (IL-1β) and tumor necrosis factor (TNF-α), apoptosis-related factor caspase-3 and Bax were detected by real-time PCR, Western blot or immunohistochemistry. The results showed that anesthesia alone caused weak cognitive dysfunction on the first day after general anesthesia. Cognitive function in mice with splenectomy under general anesthesia was significantly exacerbated at the first and third days after surgery, and was significantly improved by dexmedetomidine administration. Splenectomy increased the expression of IL-1β, TNF-α, Bax and caspase-3 in hippocampus. These changes were significantly inversed by dexmedetomidine. These results suggest that hippocampal inflammatory response and neuronal apoptosis may contribute to POCD, and selective alpha 2 adrenal receptor excitation play a protective role.

    Patients with aneurysmal coronary artery fistulas are often a treatment challenge. We hereby, report a case of aneurysmal left main coronary artery to coronary sinus fistula repair, complicated by an early post-operative thrombosis of the left main coronary artery, necessitating an orthotropic heart transplant. Routine use of peri-procedural and long-term anti-coagulation is usually not a standard recommendation in these cases; however, early institution of the same may prevent flow stasis, thrombus formation and unfavourable outcomes pre- or post-operatively.

    We aimed to determine the factors predicting liver cirrhosis-related complications in the early postoperative period after lung cancer surgery in patients with liver cirrhosis. We retrospectively reviewed the medical records of patients who underwent curative surgery for primary lung cancer in our institute from January 1990 to March 2007, finding 37 cases with comorbid liver cirrhosis. These patients were divided into two groups, according to whether liver failure, bleeding, and critical infection had occurred postoperatively. Various clinical parameters were analyzed statistically between the bigeminal groups. Liver cirrhosis-related complications occurred in seven of the 37 patients (18.9%). Transient liver failure occurred in two patients (5.4%) after pulmonary resection. Acute intrathoracic bleeding occurred in four cases (10.8%). Two patients died (5.4%) in both cases due to sepsis. Preoperative total bilirubin (P<0.05), and indocyanine green retention rate at 15 min (P<0.05) were significantly higher in patients with liver failure. Only serum value of total bilirubin was an independent risk factor (P<0.05) by multivariate analysis. In predicting death from infection, only preoperative nutritional status was a significant risk factor (P<0.05). To avoid postoperative cirrhosis-related complications, preoperative preparation to improve their liver function and nutrition status is essential.

    Early postoperative neuroimaging has been performed in people for over 20 years to detect residual brain tumor tissue and surgical complications. The purpose of this retrospective study was to describe characteristics observed using early postoperative magnetic resonance imaging in a group of dogs undergoing craniotomy for brain tumor removal. Two independent observers came to a consensus opinion for presence/absence of the following MRI characteristics: residual tumor tissue; hemorrhage and ischemic lesions; abnormal enhancement (including the margins of the resection cavity, choroid plexus, meninges) and signal intensity changes on diffusion-weighted imaging. Five dogs were included in the study, having had preoperative and early postoperative MRI acquired within four days after surgery. The most commonly observed characteristics were abnormal meningeal enhancement, linear enhancement at margins of the resection cavity, hemorrhage, and a thin rim of hyperintensity surrounding the resection cavity on diffusion-weighted imaging. Residual tumor tissue was detected in one case of an enhancing tumor and in one case of a tumor containing areas of hemorrhage preoperatively. Residual tumor tissue was suspected but could not be confirmed when tumors were nonenhancing. Findings supported the use of early postoperative MRI as a method for detecting residual brain tumor tissue in dogs.

    Although bottle-feeding after cheiloplasty is widely accepted, postoperative feeding regimen after palatoplasty is still controversial. The aim of this prospective randomized study was to evaluate the effect of bottle-feeding on early postoperative course after palatoplasty in a relatively homogeneous group of patients. Eighty-two consecutive patients with nonsyndromic cleft palate undergoing 2-flap palatoplasty by a single surgeon were randomized to feeding from a bottle with the usual nipple (G1, N = 42) or to feeding with a spoon, cup, or syringe (G2, N = 40). Complication rates, postoperative sedative use, oral intake for the first 6 days, and relative weight gain at 1 and 2 months were compared. There were no significant complications such as bleeding or respiratory problem. The overall complication rate including wound dehiscence and oronasal fistula was similar in G1 and G2 (11.9% versus 12.5%, P = 1.000) as was postoperative sedative use and mean daily oral intake for the first 5 days. Mean intake on the sixth day was significantly higher in G1. There were no significant between-group differences in relative weight gain after 1 and 2 months. In conclusion, bottle-feeding had no adverse effect on the early postoperative course after palatoplasty including complication rate, oral intake, and weight gain. These findings suggest that an unrestricted feeding regimen is appropriate immediately after palatoplasty.

    INTRODUCTION Obstructive sleep apnoea (OSA) is the most common sleep-related breathing disorder associated with multisystemic organ involvement. The STOP-BANG questionnaire is a concise, validated questionnaire that is used to screen for OSA. This study aimed to establish the use of the STOP-BANG questionnaire for perioperative patient risk stratification. METHODS In this retrospective cohort study, we extracted the demographic, medical and perioperative outcome data of all patients who underwent elective surgery, excluding ophthalmic surgeries, from January to December 2011. Multivariate regression analysis was used to predict independent risk factors for intraoperative and early postoperative adverse events. RESULTS Of the 5,432 patients analysed, 7.4% had unexpected intraoperative and early postoperative adverse events. We found that the risk of unexpected intraoperative and early postoperative adverse events was greater in patients with STOP-BANG scores ≥ 3 compared to those with a STOP-BANG score of 0 (score 3: odds ratio [OR] 3.6, 95% confidence interval [CI] 2.1–6.3, p < 0.001; score 4: OR 3.4, 95% CI 1.8–6.5, p < 0.001; score 5: OR 6.4, 95% CI 2.7–15.0, p < 0.001; score ≥ 6: OR 5.6, 95% CI 2.1–15.4, p < 0.001). Patients with STOP-BANG scores ≥ 5 had a fivefold increased risk of unexpected intraoperative and early postoperative adverse events, while patients with STOP-BANG scores ≥ 3 had a ‘one in four’ chance of having an adverse event. Other independent predictors included older age (p < 0.001), American Society of Anesthesiologists class ≥ 2 (p < 0.003) and uncontrolled hypertension (p = 0.028). CONCLUSION STOP-BANG score may be used as a preoperative risk stratification tool to predict the risk of intraoperative and early postoperative adverse events. PMID:25917473

    A prospective evaluation of /sup 111/In-labeled platelet scintigraphy (IPS) for the early diagnosis of acute postoperative renal transplant rejection (TR) was undertaken. The results of IPS were compared with in vitro biochemical tests, the clinical finding of graft tenderness, and combined (/sup 99m/Tc)DTPA and (/sup 131/I)orthoiodohippurate scintigraphy. With a sensitivity of 0.93 and a specificity of 0.95, IPS provided otherwise unavailable diagnostic information. Furthermore, postoperative IPS was a good predictor of long-term allograft survival.

    Imaging the lumbar spine after surgery for disk herniation is all too often an unrewarding challenge. A constellation of findings is inevitable, and determining their significance is often impossible. The challenge is greatest during the first few months following surgery, when the rules of scar enhancement, deformity, and mass effect do not apply to differentiation of the abnormal from the normal. A clear understanding of normal postoperative healing is necessary to avoid overreaction to misleading findings. This report reviews imaging of the lumbar spine in the early postoperative period (i.e., the first 6 months after surgery), focusing on the normal healing process that so often mimics complicating or recurrent disease.

    Background The aim of this study was to examine the association between serum expression of miRNA-155 and postoperative cognitive dysfunction (POCD) after laparoscopic surgery for colon cancer. Material/Methods We enrolled 110 patients scheduled to undergo colon tumor resection via laparotomy in Ningbo No. 2 Hospital from July 2013 to November 2015. The blood samples were collected from the participants 1 day before surgery. Multiple logistic regression analysis was used for the analysis of independent predictive biomarkers for POCD. Results On the 7th postoperative day, 29 of the 110 participants developed POCD, yielding a POCD incidence of 26.4%. Age, MMSE score, duration of surgery and anesthesia, serum levels of CRP, TNF-α, urea, creatinine, and miRNA-155 were highly associated with the occurrence of POCD. Serum expression of miRNA-155 was shown by multiple logistic regression analysis to be an independent predictive indicator for POCD after surgery (OR: 2.732; 95%CI 1.415–5.233; P=0.002). Conclusions The serum expression of miRNA-155 is an independent predictive factor for POCD after laparoscopic surgery for colon cancer. PMID:27872469

    Abstract Background: The administration of oral pregabalin preoperatively has been reported to reduce acute postoperative pain. However, no clinical study to date has yet fully investigated whether or not pregabalin premedication affects sensory and motor blocks using spinal anesthesia and its effect upon early postoperative pain management. This prospective, randomized, and double-blind clinical study was designed to evaluate the efficacy of a single dose of pregabalin in terms of spinal blockade duration and its potential opioid-sparing effect during the first 24 hours subsequent to urogenital surgery. Methods: Forty-four patients scheduled for urogenital surgery under spinal anesthesia were randomly allocated to 2 groups: group C (no premedication; orally administered placebo 2 hours before surgery) and group P (orally administered 150 mg pregabalin 2 hours before surgery). Results: The duration of sensory and motor blockade was significantly prolonged in group P patients when compared with that in group C patients, and the pain scores at postoperative 6 and 24 hours were significantly lower in group P patients. Requests for analgesics during the first postoperative 24 hours were lower among group P patients. Conclusion: Premedication with a single dose of 150 mg pregabalin before surgery promoted the efficacy of intrathecal bupivacaine and improved postoperative analgesia in patients undergoing urogenital surgery under spinal anesthesia.

    The impact of early enteral nutrition (EEN) on clinical outcomes of gastric cancer patients was investigated. Three hundred pa-tients undergoing gastric cancer surgery from July 2010 to May 2014 were randomly divided into experimental and control groups (n = 150/group). Experimental group patients received enteral nutrition in water during the early postoperative period. Control group patients received conventional perioperative treatment. Patients' clinical outcomes, post-operative immune function, and nutritional statuses were compared, which revealed that the postoperative fever duration (80.2 ± 6.0 vs 88.1 ± 8.1 h, P < 0.05), anal exhaust time (78.8 ± 9.3 vs 85.3 ± 8.4 h, P < 0.05), and length of hospitalization (7.73 ± 2.13 vs 9.77 ± 1.76 days, P < 0.01) differed significantly. Treatment costs in thousands of dol-lars were 31.24 ± 3.21 for the experimental group and 35.61 ± 2.32 for the control group; this difference was statistically significant (P < 0.01). The incidence of postoperative complications did not significantly differ between the experimental and control groups [14.0% (21/150) vs 17.3% (26/150), P > 0.05]. At postoperative days 3 and 7, the CD3(+), CD4(+), natural killer cell, albumin, and prealbumin levels and CD4(+)/CD8(+) ra-tio were significantly higher in the experimental group than the control group (all P < 0.05). CD8(+) cell counts were significantly lower in the experimental group than the control group (P < 0.05). Postsurgical oral EEN can improve nutritional status and immune function and promote early recovery of intestinal function in patients with gastric cancer.

    In a group of cadaveric kidney transplantations the problem of the dependence of the functional development of the graft on the function of donor kidney before explanation and on the total time of ischaemia in the immediate postoperative period was investigated. Based on the plasma concentration of endogenous creatinine (PKr), urea (PUrea) and the total ischaemic time (GI), the early function of the graft cannot be predicted. On the contrary, the values of PKr, GI and the kidney index (NIKI = PKr x GI) allow an accurate prediction that the early function of the graft will not be sufficient. Early function of the graft is not likely to develop when PKr is higher than 160 mumol/l, total ischaemic time is longer than 30 hours and the NIKI is over 3,500. Severe alterations in the level of serum potassium (SK) occurred in 61.4% of the donors. In cases where SK was 3.0 mmol/l or less, early function of the graft did not develop in 82.3%. With high probability haemodialysis was necessary. More pronounced alterations of the level of SNa occurred in more than 60% of the donors. When SNa was 125 mmol/l or less, early function of the graft did not develop in 76%. Diuresis over 400 ml/h increased significantly the number of early nonfunctional grafts. In cases where fractional sodium excretion (FENa) was over 5%, early function of the graft did not develop. With a FENa less or equal to 1%, early function of the graft was most likely to develop.

    We compared early postoperative complications between trabeculectomy and Ex-PRESS implantation. Enrolled patients with 39 primary open-angle or 25 exfoliative glaucoma were randomly assigned to receive trabeculectomy (trabeculectomy group) or Ex-PRESS implantation (Ex-PRESS group). Primary outcomes were early postoperative complications, including postoperative anterior chamber inflammation, frequencies of hyphema, flat anterior chamber, choroidal detachment, hypotonic maculopathy, and the change of visual acuity. The postoperative flare values in trabeculectomy group were higher than those in the Ex-PRESS group (overall, P = 0.004; and 10 days, P = 0.02). Hyphema occurred significantly more frequently in the trabeculectomy group (P = 0.0025). There were no significant differences of the other primary outcomes between the two groups. Additionally, duration of anterior chamber opening was significantly shorter in the Ex-PRESS group (P = 0.0002) and the eyes that had iris contact with Ex-PRESS tube had significantly shallower anterior chambers than did the eyes without the iris contact (P = 0.013). The Ex-PRESS implantation prevented early postoperative inflammation and hyphema in the anterior chamber and shortened the duration of anterior chamber opening. Iris contact with the Ex-PRESS tube occurred more frequently in eyes with open-angle glaucoma and shallow anterior chambers.

    Background: Previous studies indicated that patients from Black, Asian and minority ethnic (BAME) groups tend to receive less analgesics compared to Caucasian (White) patients after similar surgical procedures. Most such data originated from North America and suggested that health-care professionals may perceive the expression of excessive pain by BAME patient groups as an exaggerated response to pain, rather than sub-optimal treatment. There are limited data comparing acute pain management between South Asian and White British patients. Objective: We aimed to investigate correlation between patients’ ethnicity and disparities of early post-operative pain perception/management, in an ethnically diverse population. Methods: We conducted a retrospective case note review of acute post-operative pain after total abdominal hysterectomy (TAH) in 60 South Asian and 60 age-matched White British females. Data for 140 variables (pre-, intra- and post-operative) for each patient were recorded. We used propensity score matching to produce 30 closely matched patients in each group minimizing effects of recorded co-variates. Data were analysed with and without propensity score matching. Results: There were no significant differences in acute post-operative pain scores, morphine requirements, pain management, adverse effects or duration of post-operative care unit stay between South Asian and White British patients. The median duration of hospital stay of South Asian patients was longer (4.5 days versus 3.0 days, p < 0.001). Conclusion: We conclude that in an institution where both patients and health-care professionals are from an ethnically diverse population, neither post-operative pain nor pain management are influenced significantly by South Asian ethnicity.

    Objective The early postoperative period following neonatal cardiac surgery is a time of increased risk for brain injury, yet the mechanisms underlying this risk are unknown. To understand these risks more completely, we quantified changes in postoperative cerebral metabolic rate of oxygen (CMRO2), oxygen extraction fraction (OEF), and cerebral blood flow (CBF) compared with preoperative levels by using noninvasive optical modalities. Methods Diffuse optical spectroscopy and diffuse correlation spectroscopy were used concurrently to derive cerebral blood flow and oxygen utilization postoperatively for 12 hours. Relative changes in CMRO2, OEF, and CBF were quantified with reference to preoperative data. A mixed-effect model was used to investigate the influence of total support time and deep hypothermic circulatory arrest duration on relative changes in CMRO2, OEF, and CBF. Results Relative changes in CMRO2, OEF, and CBF were assessed in 36 patients, 21 with single-ventricle defects and 15 with 2-ventricle defects. Among patients with single-ventricle lesions, deep hypothermic circulatory arrest duration did not affect relative changes in CMRO2, CBF, or OEF (P > .05). Among 2-ventricle patients, total support time was not a significant predictor of relative changes in CMRO2 or CBF (P > .05), although longer total support time was associated significantly with greater increases in relative change of postoperative OEF (P = .008). Conclusions Noninvasive diffuse optical techniques were used to quantify postoperative relative changes in CMRO2, CBF, and OEF for the first time in this observational pilot study. Pilot data suggest that surgical duration does not account for observed variability in the relative change in CMRO2, and that more comprehensive clinical studies using the new technology are feasible and warranted to elucidate these issues further.

    There is a number of factors such as the thyroidectomy and limiting subtotal thyroid resection against the background of euthyroidism and initial hypothyroidism (in any extent of operation) which leads to the prediction of early postoperative hypothyroidism origin during 10 days of the postoperative peri- od. The early postoperative hypothyroidism is accompanied by activation processes of lipid peroxide oxidation and at the same time by reduction of antioxidant protection.

    Objective Lymphedema is a chronic major complication that is seen frequently post-operatively and has negative effects on quality of life. In our study, determining the early-stage postoperative lymphedema frequency and specifying the risk factors in its development has been aimed. Materials and Methods One hundred one cases that were operated on for breast cancer were evaluated regarding the 12-month control of their clinical specifications, histopathological specifications, and specifications related with the surgical intervention retrospectively. The data related to the parameters envisioned as risk factors were evaluated. Results Lymphedema development was found in 7 (6.9%) out of 101 cases constituting the study group. No significant difference (p>0.05) in terms of lymphedema development was determined among age, body mass index (BMI), chemotherapy (CT), postoperative seroma or infection, mastectomy with the dominant arm, and breast-conserving surgery (BCS), which were evaluated as risk factors. There was a significance (p<0.05) between the other risk factors, which were axillary dissection (AD), number of positive lymph nodes (LN), radiotherapy (RT), the tumor size (T), and lymphedema existence. In every case in which lymphedema was determined, it was seen that there was axillary LN involvement and 15≤LN were ablated in the dissection (p<0.05). Conclusion It is seen that AD, RT applied to the breast cancer patients, and T are important risk factors in early-stage lymphedema development. No early-stage lymphedema development was determined in any of the patients to whom sentinel lymph node dissection (SLND) was applied.

    This prospective randomized study compares the clinical results of immediate passive mobilization versus delayed mobilization in the rehabilitation of rotator cuff repair during the early postoperative period. The mobilization group (79 patients) received immediate daily passive mobilization. The immobilization group (51 patients) was immobilized for 4 weeks until physiotherapy was started. Passive range of motion was noted preoperatively, at 6 weeks and 4 months. Strength was measured preoperatively and at 4 months. Constant-Murley, Simple Shoulder Test, SPADI and UCLA scores were noted at baseline and at 4 months. Ultrasonography was performed at 6 weeks to exclude early failures of repair. We noted no significant difference between the two groups regarding range of motion at 6 weeks and range of motion, strength and functional outcome scores at 4 months. Ultrasound didn't show a difference in healing at 6 w in either of both groups. Both rehabilitation protocols seem applicable as well as safe in the early post-operative phase.

    We studied 37 children soon after ureteroneocystostomy using diuretic radionuclide urography to assess the patency of the ureterovesical junction. Postoperative obstruction was excluded correctly in 90 per cent of the patients. Transient ureterovesical obstruction occurred in 5 patients, identification of which was useful in assigning risk and in guiding followup studies. Because it is a safe, noninvasive and relatively low radiation test the diuretic radionuclide urogram proves to be an attractive alternative to the excretory urogram in the early and late followup of patients undergoing a ureterovesical junction operation.

    Background: Respiratory and renal insufficiencies are common dysfunctions during post-liver transplantation period that increase post-operative mortality and morbidity rates. Intra-operative fluid therapy is an important factor associated with pulmonary and renal insufficiency. Objective: To evaluate the relation between intra-operative fluid therapy and early renal and respiratory insufficiency after liver transplantation. Methods: In this randomized clinical study, 67 adult patients with end-stage liver disease who underwent orthotopic deceased donor liver transplantation were randomly allocated into two groups. The restricted fluid group, which received a controlled fluid administration of normal saline, 5 mL/kg/hr during anesthesia, and non-restricted fluid group received a controlled infusion of normal saline 10 mL/kg/hr during anesthesia. Early post-operative respiratory and renal insufficiency in both groups were assessed. The patients were monitored during the three stages of liver transplantation for their hemodynamic indices. The trial is registered with the Iranian Randomized Clinical Trial Registry, number IRCT2013101811662N4. Results: The baseline demographic and clinical characteristics were similar in both studied groups. The prevalence of respiratory insufficiency in the non-restricted fluid group (15%) significantly (p=0.01) higher than that in the restricted fluid group (0%). The post-operative mean±SD serum creatinine was 1.0±0.1 mg/dL in the non-restricted fluid group and 1.1±0.2 in the restricted fluid group (p=0.43). No patients in the studied groups required post-operative continuous renal replacement therapy. Conclusions: Restricted crystalloid fluid administration during orthotropic liver transplantation though decreased post-operative chance of pulmonary insufficiency, did not increase renal dysfunction.

    Kidney transplant is inevitably subjected to ischemic and reperfusion injury. In many cases, this is due to a violation of intraorgan hemodynamics. Severity of such damage can be reduced using different methods of extracorporeal hemocorrection. The aim of the study was to examine the intraorgan blood flow of kidney transplant and assess the impact of plasmapheresis on its primary function in the early postoperative period. Plasmapheresis with replacement from 1,25 to 3,5 liters of plasma was applied in 40 recipients of the Group 1; in 40 recipients of Group 2 plasmapheresis was not performed. High resistance index (Ri > 0,9) at low flow velocities in the interlobular arteries at the first day after surgery is an informative criterion for the diagnosis of acute tubular necrosis and indicates the inadequate blood supply of kidney. Plasmapheresis has promoted the normalization of renal hemodynamics. Immediate graft function in patients of Group 1 was observed in 36 patients, whereas only in 19 patients of Group 2. In the Group 1, there were no patients with primary non-functioning graft, while there were three such patients in Group 2. Thus, plasmapheresis in the early postoperative period, no later than 3-5 h after reperfusion of the graft, has a positive effect on the functional status of the transplanted kidney.

    We examined colon cancer patients who received soluble dietary fiber enteral nutrition (SDFEN) to evaluate the feasibility and potential benefit of early SDFEN compared to EN. Sixty patients who were confirmed as having colon cancer with histologically and accepted radical resection of colon cancer were randomized into an SDFEN group and an EN group. The postoperative complications, length of hospital stay (LOH), days for first fecal passage, and the difference in nutritional status, immune function and inflammatory reaction between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test and the chi square test. Statistical significance was defined as p < 0.05. After the nutrition support, differences in the levels of albumin, prealbumin and transferrin in each group were not statistically significant (p > 0.05); the levels of CD4+, IgA and IgM in the SDFEN group were higher than that of the EN group at seven days (p < 0.05); the levels of TNF-α and IL-6 in the SDFEN group were lower than that of the EN group at seven days (p < 0.05); and patients in the SDFEN group had a significantly shorter first flatus time than the EN group (p < 0.05). Early post-operative SDFEN used in colon cancer patients was feasible and beneficial in immune function and reducing inflammatory reaction, gastrointestinal function and speeding up the recovery.

    Background and Objectives: Adequate nutritional supplementation in infants with cardiac malformations after surgical repair is a challenge. Critically ill infants in the early postoperative period are in a catabolic stress. The mismatch between estimated energy requirement (EER) and the intake in the postoperative period is multifactorial, predisposing them to complications such as immune deficiency, more infection, and growth failure. This study aimed to assess the feasibility and efficacy of enriched breast milk feed on postoperative recovery and growth of infants after open heart surgery. Methodology: Fifty infants <6 months of age were prospectively randomized in the trial for enteral nutrition (EN) postoperatively from day 1 to 10, after obtaining the Institute Ethics Committee's approval. They were equally divided into two groups on the basis of the feed they received: Control group was fed with expressed breast milk (EBM; 0.65 kcal/ml) and intervention group was fed with EBM + energy supplementation/fortification with human milk fortifier (7.5 kcal/2 g)/Simyl medium-chain triglyceride oil (7.8 kcal/ml). Energy need for each infant was calculated as per EER at 90 kcal/kg/day, as the target requirement. The intra- and post-operative variables such as cardiopulmonary bypass and aortic cross-clamp times, ventilation duration, Intensive Care Unit (ICU), and hospital length of stay and mortality were recorded. Anthropometric and hematological parameters and infection control data were recorded in a predesigned pro forma. Data were analyzed using Stata 14.1 software. Results: The duration of mechanical ventilation, length of ICU stay (LOIS), length of hospital stay (LOHS), infection rate, and mortality rate were lower in the intervention group compared to the control group although none of the differences were statistically significant. Infants in control group needed mechanical ventilation for about a day more (i.e., 153.6 ± 149.0 h vs. 123.2 ± 107.0 h; P = 0

    Introduction Liver transplantation is one of the best treatment options for end-stage liver disease. In Turkey, living donor liver transplantation (LDLT) is performed more frequently than cadaveric transplantation, because organ donation is unpopular in our country. Neurological complications contribute to poor postoperative outcomes after liver transplantation. In the present study, we aimed to evaluate the outcomes of LDLT patients in whom such complications developed early during postoperative follow-up in the intensive care unit. Methods Of 217 LDLTs performed between August 2011 and August 2012, neurology consultations were arranged for 29 patients (13.36%) because of development of new-onset neurological symptoms and/or findings in patients with neurologically uneventful preoperative histories. We retrospectively collected data on age, gender, primary disease, Model for End-Stage Liver Disease (MELD) score, and postoperative hospitalization duration of those who survived. The indications for neurological consultation and diagnoses were categorized into acute confusion/encephalopathy, epileptic seizures, leukoencephalopathy, and focal neurological deficits. The immunosuppressive treatment regimens prescribed were also considered. The outcomes of the 2 groups (with and without neurological complications) were compared. Results The mean patient age was 44.52±16.24 years, and males predominated (65.5%, n=19). Acute confusion/encephalopathy was the most frequent complication (62.1%, n=18), followed by epileptic seizures (27.6%, n=8), cerebrovascular disease (6.9%, n=2), and leukoencephalopathy (3.4%, n=1). Statistically significant between-group differences in age (44.5±16.2 vs. 34.33±20.98 years; p<0.001), and proportions of patients with a disease of viral etiology (55.17% vs. 35.63%, p<0.05), were evident. Mortality was significantly higher in the group with neurological complications (65.5% vs. 37.32%, p<0.05). The duration of postoperative hospitalization

    Evidence is mixed for an association between serum insulin-like growth factor-I (IGF-I) levels and postoperative delirium (POD). The current study assessed preoperative serum IGF-I levels as a predictor of incident delirium in non-demented elderly elective knee arthroplasty patients. Preoperative serum levels of total IGF-I were measured using a commercially available Human IGF-I ELISA kit. POD incidence and severity were determined using DSM-IV criteria and the Delirium Rating Scale-Revised-98 (DRS-R98), respectively. Median IGF-I levels in delirious (62.6 ng/ml) and non-delirious groups (65.9 ng/ml) were not significantly different (p = 0.141). The ratio (95% CI) of geometric means, D/ND, was 0.86 (0.70, 1.06). The Hodges-Lehmann median difference estimate was 7.23 ng/mL with 95% confidence interval (-2.32, 19.9). In multivariate logistic regression analysis IGF-I level was not a significant predictor of incident POD after correcting for medical comorbidities. IGF-I levels did not correlate with DRS-R98 scores for delirium severity. In conclusion, we report no evidence of association between serum IGF-I levels and incidence of POD, although the sample size was inadequate for a conclusive study. Further efforts to investigate IGF-I as a delirium risk factor in elderly should address comorbidities and confounders that influence IGF-I levels.

    Background In most people with low-grade gliomas (LGG), the primary treatment regimen remains a combination of surgery followed by postoperative radiotherapy. However, the optimal timing of radiotherapy is controversial. It is unclear whether to use radiotherapy in the early postoperative period, or whether radiotherapy should be delayed until tumour progression occurs. Objectives To assess the effects of early postoperative radiotherapy versus radiotherapy delayed until tumour progression for low-grade intracranial gliomas in people who had initial biopsy or surgical resection. Search methods We searched up to September 2014 the following electronic databases: the Cochrane Register of Controlled Trials (CENTRAL, Issue 8, 2014), MEDLINE (1948 to Aug week 3, 2014), and EMBASE (1980 to Aug week 3, 2014) to identify trials for inclusion in this Cochrane review. Selection criteria We included randomised controlled trials (RCTs) that compared early versus delayed radiotherapy following biopsy or surgical resection for the treatment of people with newly diagnosed intracranial LGG (astrocytoma, oligodendroglioma, mixed oligoastrocytoma, astroblastoma, xanthoastrocytoma, or ganglioglioma). Radiotherapy may include conformal external beam radiotherapy (EBRT) with linear accelerator or cobalt-60 sources, intensity-modulated radiotherapy (IMRT), or stereotactic radiosurgery (SRS). Data collection and analysis Three review authors independently assessed the trials for inclusion and risk of bias, and extracted study data. We resolved any differences between review authors by discussion. Adverse effects were also extracted from the study report. We performed meta-analyses using a random-effects model with inverse variance weighting. Main results We included one large, multi-institutional, prospective RCT, involving 311 participants; the risk of bias in this study was unclear. This study found that early postoperative radiotherapy is associated with an increase in time to

    The objective of the present work was to study peculiarities of the analgesic action of therapeutic electrical stimulation (TES therapy) in the early postoperative period in the patients who underwent tonsillectomy. A total of 60 patients admitted for this surgery to the specialized otorhinolaryngological department were available for observation. They were divided into two groups depending on the pain relief strategy. The patients of the study group (n=30) underwent courses of transcranial electrical stimulation on a daily basis (from the onset of hospitalization) in addition to the administration of a standard analgetic. The standard dose of tramadol (2.0 ml) was given to the patients of the control group (n=30) who complained of strong pain. The results of the objective and subjective estimations indicate that the degree of pharyngeal pain in the patients treated with TES therapy and the standard analgetic was significantly different. The patients receiving TES therapy could sooner resume their habitual diet and required smaller amounts of the analgetic which makes this modality a cost-effective supplement to the standard postoperative treatment.

  9. Early ambulation and prevention of post-operative thrombo-embolic risk.

    The prevention of post-operative risk of venous thrombo-embolism (VTE) is of fundamental importance, but preventive methods have progressed with the introduction of direct oral anticoagulants (DOAC), the development of ambulatory surgery and enhanced recovery programs (ERP) after surgery. Surgery is, inherently a trigger for venous thrombo-embolic disease, as is prolonged immobilization. However, the risk of VTE is very low following ambulatory surgery, especially in this selected population. ERP, consists of a set of measures to optimize the patient's peri-operative management while reducing length of stay, costs and morbidity and mortality; one measure is the encouragement of early ambulation. This will undoubtedly have an impact on the incidence of VTE and lessen the need for prolonged thrombo-prophylaxis.

    In-vivo measurement of tibiofemoral forces transmitted through Total Knee Replacement (TKR) during normal walking allows the early detection of postoperative complications such as the tibiofemoral misalignment and soft-tissue imbalance. In addition, the in-vivo data can help to improve the design of TKR in order to reduce polyethylene wear and consequently to increase the lifespan of knee implant. A self-powered custom-designed tibial implant instrumented with four piezoceramics has been developed in order to detect the aforementioned complications by measuring the relative change in pressure center (COP) position for different levels of eccentric compressive loading. Moreover, the energy harvested by the piezoceramics can be used to power a transmission system located at the stem of knee implant to wirelessly transmit the in-vivo data outside the implant for further processing and display.

    Numerous basic drugs are extensively bound to alpha 1-acid glycoprotein. Fentanyl, with a pKa value of 8.43, is also a basic drug. Protein binding studies have yielded contradictory results concerning binding of fentanyl to alpha 1-acid glycoprotein. In this study we investigated time courses of serum protein concentrations and serum protein binding of fentanyl during postoperative acute phase reaction, assuming that an increase of alpha 1-acid glycoprotein is accompanied by an increase of serum protein binding, if fentanyl is extensively bound to alpha 1-acid glycoprotein. Fentanyl protein binding measurements using equilibrium dialysis can be affected by volume shifts and pH changes. Therefore, volume shifts from buffer to serum and the influence of various phosphate buffers on increasing pH due to loss of CO2 were also evaluated. METHODS. Thirteen patients with no history of renal or hepatic disease undergoing an operation with a significant acute phase reaction were studied. Preoperatively and on the first 3 postoperative days serum concentrations of alpha 1-acid glycoprotein, albumin, total protein and apolipoprotein A and B were determined by rocket immunoeolectrophoresis, biuret method and laser nephelometry, respectively. Corresponding serum protein binding of fentanyl was measured by adding 40 ng of fentanyl to 1 ml serum followed by equilibrium dialysis at 37 degrees C for 4 h. A 0.167 M phosphate buffer (pH 7.27), which gave a final pH of 7.40, was used. Volume shifts from buffer to serum were measured. Fentanyl concentration in serum before dialysis (FS) was determined by gas chromatography, and fentanyl concentration in buffer after dialysis (FB) was determined by radioimmunoassay. Serum protein binding (SPB) was calculated by the formula: SPB = (FS - FB - FB*c)/(FS - FB) where c is a correction factor. Ten randomly selected patient sera were dialyzed against four phosphate buffers of different pH values and molarities, and the serum pH at the end of

    Cerebral blood flow (CBF) was measured in 90 patients who underwent early aneurysmal clipping after subarachnoid hemorrhage (SAH). Measurements were made by a noninvasive, two-dimensional method involving intravenous injection of 133Xe. Patients of Hunt and Hess grades I and II exhibited normal to slightly subnormal CBF, without significant changes, during the study period. Grades III-V patients had almost normal CBF in the early postoperative period, but their CBF gradually decreased, becoming significantly low after day 31. It is noteworthy that in grades IV and V patients, CBF was abnormally high in the acute stage, relative to their poor neurological condition; these patients were considered to have the "global luxury perfusion syndrome." The syndrome was not uncommon in patients with severe SAH. Possible causative or contributory factors are attempts to surgically reduce intracranial pressure, which leads to increased cerebral perfusion pressure, and concomitant global dysautoregulation. In patients with this syndrome, maneuvers intended to increase CBF should be avoided, as they may aggravate brain swelling or cause hemorrhagic events. Positron emission tomographic studies will provide more accurate and useful information concerning the management of SAH patients.

    Background Laparoscopic gastrectomy requires a reverse-Trendelenburg position and prolonged pneumoperitoneum and it could cause significant changes in cerebral homeostasis and lead to cognitive dysfunction. We compared changes in regional cerebral oxygen saturation (rSO2), early postoperative cognitive function and hemodynamic variables in patients undergoing laparoscopic gastrectomy with those patients that underwent conventional open gastrectomy. Methods Sixty patients were enrolled in this study and the patients were distributed to receive either laparoscopic gastrectomy (laparoscopy group, n = 30) or open conventional gastrectomy (open group, n = 30). rSO2, end-tidal carbon dioxide tension, hemodynamic variables and arterial blood gas analysis were monitored during the operation. The enrolled patients underwent the mini-mental state examination 1 day before and 5 days after surgery for evaluation of early postoperative cognitive function. Results Compared to baseline value, rSO2 and end-tidal carbon dioxide tension increased significantly in the laparoscopy group after pneumoperitoneum, whereas no change was observed in the open group. No patient experienced cerebral oxygen desaturation or postoperative cognitive dysfunction. Changes in mean arterial pressure over time were significantly different between the groups (P < 0.001). Conclusions Both laparoscopic and open gastrectomy did not induce cerebral desaturation or early postoperative cognitive dysfunction in patients under desflurane anesthesia. However, rSO2 values during surgery favoured laparoscopic surgery, which was possibly related to increased cerebral blood flow due to increased carbon dioxide tension and the effect of a reverse Trendelenburg position.

    Various clinical trials have assessed how intraoperative anesthetics can affect early recovery, hemodynamics and nociception after supratentorial craniotomy. Whether or not the difference in recovery pattern differs in a meaningful way with anesthetic choice is controversial. This review examines and compares different anesthetics with respect to wake-up time, hemodynamics, respiration, cognitive recovery, pain, nausea and vomiting, and shivering. When comparing inhalational anesthetics to intravenous anesthetics, either regimen produces similar recovery results. Newer shorter acting agents accelerate the process of emergence and extubation. A balanced inhalational/intravenous anesthetic could be desirable for patients with normal intracranial pressure, while total intravenous anesthesia could be beneficial for patients with elevated intracranial pressure. Comparison of inhalational anesthetics shows all appropriate for rapid emergence, decreasing time to extubation, and cognitive recovery. Comparison of opioids demonstrates similar awakening and extubation time if the infusion of longer acting opioids was ended at the appropriate time. Administration of local anesthetics into the skin, and addition of corticosteroids, NSAIDs, COX-2 inhibitors, and PCA therapy postoperatively provided superior analgesia. It is also important to emphasize the possibility of long-term effects of anesthetics on cognitive function. More research is warranted to develop best practices strategies for the future that are evidence-based. PMID:26345202

    Introduction: Urinary tract infection (UTI) is one of the most common bacterial infections in children that can be associated with renal parenchymal injuries and late scars. Dimercaptosuccinic acid (DMSA) renal scan is known as golden standard for detecting acute pyelonephritis (APN) that has a lot of difficulties and limitations. Objectives: we designed this study the accuracy of one inflammatory marker, serum procalcitonin (PCT) to identify as an early predictor of renal injuries. Patients and Methods: A prospective study was carried out in 95 patients who admitted in the hospital with the first febrile UTI. Serum PCT of all patients was measured; sensitivity, specificity, positive and negative predictive value (PPV and NPV) of this marker was analyzed compared to DMSA scan. P value <0.05 was taken as significant. Results: In total, 79 females and 16 males were investigated. There are 42 cases in group 1 with normal DMSA scan and 53 patients in group two with renal parenchymal injuries in their scans. Mann-Whitney test showed a meaningful relation between the two groups regarding PCT level (P<0.0001). Sensitivity, specificity, PPV and NPV of PCT reported in optimum cut off were 70%, 88.1%, 88.1% and 70%, respectively. The positive likelihood ratio (PLR) of PCT test was 5.8. Conclusion: In the current survey, PCT was the eligible inflammatory marker to predict renal parenchymal injuries in children with proper sensitivity, specificity, PPV and NPV that play also a pivotal role in the children aged less than 24 months, although, more studies should be undertaken to confirm.

    Purpose: To report dosimetry and early toxicity data in breast cancer patients treated with postoperative proton radiation therapy. Methods and Materials: From March 2013 to April 2014, 30 patients with nonmetastatic breast cancer and no history of prior radiation were treated with proton therapy at a single proton center. Patient characteristics and dosimetry were obtained through chart review. Patients were seen weekly while on treatment, at 1 month after radiation therapy completion, and at 3- to 6-month intervals thereafter. Toxicity was scored using Common Terminology Criteria for Adverse Events version 4.0. Frequencies of toxicities were tabulated. Results: Median dose delivered was 50.4 Gy (relative biological equivalent [RBE]) in 5 weeks. Target volumes included the breast/chest wall and regional lymph nodes including the internal mammary lymph nodes (in 93%). No patients required a treatment break. Among patients with >3 months of follow-up (n=28), grade 2 dermatitis occurred in 20 patients (71.4%), with 8 (28.6%) experiencing moist desquamation. Grade 2 esophagitis occurred in 8 patients (28.6%). Grade 3 reconstructive complications occurred in 1 patient. The median planning target volume V95 was 96.43% (range, 79.39%-99.60%). The median mean heart dose was 0.88 Gy (RBE) [range, 0.01-3.20 Gy (RBE)] for all patients, and 1.00 Gy (RBE) among patients with left-sided tumors. The median V20 of the ipsilateral lung was 16.50% (range, 6.1%-30.3%). The median contralateral lung V5 was 0.34% (range, 0%-5.30%). The median maximal point dose to the esophagus was 45.65 Gy (RBE) [range, 0-65.4 Gy (RBE)]. The median contralateral breast mean dose was 0.29 Gy (RBE) [range, 0.03-3.50 Gy (RBE)]. Conclusions: Postoperative proton therapy is well tolerated, with acceptable rates of skin toxicity. Proton therapy favorably spares normal tissue without compromising target coverage. Further follow-up is necessary to assess for clinical outcomes and cardiopulmonary

    Early anastomotic leakage (AL), usually defined as leakage within 30 post-operative days, represents a severe entity. However, mounting evidence has indicated that majorities of leakage occur within one week after surgery, making late AL rarity. Here we analyzed 101 consecutive colorectal AL, all of which occurred within 30 post-operative days, during Jan 2013 and Dec 2015 in cancer hospital of Fudan University. AL occurring within 5 post-operative days was defined as very early AL (vE-AL). We evaluated risk factors of vE-AL compared with non-vEAL and correlated with post-leakage peritonitis and need of relaparatomy. We found that AL occurred at median time of 7 days after surgery. 23 cases were vE-AL. Reconstruction of post-peritoneum for mid-low rectal carcinoma significantly reduced incidence of vE-AL compared with non-vE-AL (p = 0.042). Patients with vE-AL was associated with presence of peritonitis (p = 0.031), the latter significantly correlated with increased re-operation rate (p = 6.8E-13). Besides, patients with vE-AL trended to correlate with increased re-operation rate after leakage (p = 0.088). In concludsion, vE-AL occurring within 5 post-operative days represents a severe subtype associated with general peritonitis and need of relaparatomy. PMID:28084305

    Study Design Case control study. Purpose To identify the most significant laboratory marker for early detection of surgical site infection (SSI) using multiple logistic regression analysis. Overview of Literature SSI is a serious complication of spinal instrumentation surgery. Early diagnosis and treatment are crucial. Methods We retrospectively reviewed the laboratory data of patients who underwent posterior lumbar instrumentation surgery for degenerative spinal disease from January 2003 to December 2014. Six laboratory markers for early SSI detection were considered: renewed elevation of the white blood cell count, higher at 7 than 4 days postoperatively; renewed elevation of the C-reactive protein (CRP) level, higher at 7 than 4 days postoperatively; CRP level of >10 mg/dL at 4 days postoperatively; neutrophil percentage of >75% at 4 days postoperatively; lymphocyte percentage of <10% at 4 days postoperatively; and lymphocyte count of <1,000/µL at 4 days postoperatively. Results Ninety patients were enrolled; five developed deep SSI. Multivariate regression analysis showed that a lymphocyte count of <1,000/µL at 4 days postoperatively was the sole significant independent laboratory marker for early detection of SSI (p=0.037; odds ratio, 11.9; 95% confidence interval, 1.2–122.7). Conclusions A lymphocyte count of <1,000/µL at 4 days postoperatively is the most significant laboratory marker for early detection of SSI. PMID:27994779

    Introduction Decreasing the diagnostic delay in axial spondyloarthritis (axSpA) remains a major challenge. Here, we assessed the value of serum inflammatory biomarkers to distinguish early axSpA from other pathologies in a large cohort of patients referred with early back pain. Methods Serum c reactive protein (CRP), erythrocyte sedimentation rate (ESR) and calprotectin were determined in the SPondyloArthritis Caught Early (SPACE) cohort (n=310), an early back pain inception cohort. Additionally, explorative serum biomarkers derived from the literature (interleukin-27 (IL-27), human β-defensin-2 (hBD-2) and lipcolin-2 (LCN-2)) were determined by ELISA in full-blown patients with ankylosing spondylitis (AS) (n=21) and healthy controls (n=20). Results Serum CRP and ESR levels were not elevated in early axSpA versus ‘control’ back pain patients. Serum calprotectin was elevated in early axSpA versus controls (p=0.01) but failed to identify early axSpA at the individual level (positive predictive value of 38.7%). As to explorative biomarkers, serum levels of IL-27 were not detectable, and hBD-2 and LCN-2 serum levels were not elevated in full-blown AS versus healthy controls (p=0.572, p=0.562, respectively). Therefore, these markers were not further determined in the SPACE cohort. Conclusions None of the candidate serum inflammatory markers were useful as diagnostic markers in the early phase of axSpA.

Aim: To assess the effect of preoperative statin therapy on POMI in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. Setting and Design: Prospective observational study in a tertiary level hospital. Methods: Sixty patients aged 45–65 years undergoing OPCAB surgery were allocated into two groups of 30 each. Group A patients were receiving statin and Group B patients were not receiving statins. All patients underwent memory function assessment preoperatively after admission to hospital and on the 6th postoperative day using postgraduate institute memory scale. Statistical Analysis: Appropriate tests were applied with SPSS 20 to compare both groups. The value P < 0.05 was considered statistically significant. Multiple regression analysis was performed with confounding factors to determine the effect on memory impairment. Results: Patients in Group A showed significant postoperative deterioration in 6 of the 10 functions and in Group B showed deterioration in 9 of 10 functions tested compared to preoperative scores. Intergroup comparison detected less POMI in Group A compared to Group B and was statistically significant in 8 memory functions. Multiple regression analysis detected statin as an independent factor in preventing memory impairment. Conclusions: Preoperative statin therapy attenuates the early POMI in patients undergoing OPCAB. Future long-term studies will define the efficacy of statin on POMI. PMID:26750672

    Background Post-thoracotomy pain is an obstacle for lung-cancer patients even after introduction of less invasive surgical procedures. The aim of this prospective study was to evaluate if early postoperative administration of pregabalin is beneficial for patients with non-small cell lung cancer (NSCLC). Methods We conducted a randomized open control trial. Patients with NSCLC were allocated randomly to epidural and nonsteroidal anti-inflammatory drug (NSAID) use for analgesia (control group) or pregabalin use (pregabalin group). Primary endpoint was the frequency of additional administration of a NSAID. Secondary endpoints were intensity of ongoing pain, frequency of neuropathic pain, and pain catastrophizing. Results Seventy-two patients were registered and allocated. Thirty-four cases in the control group and 33 in the pregabalin group were assessed. Age, sex, body mass index (BMI), type of surgical procedure, type of lymph-node dissection, operation time, bleeding, duration of chest-tube insertion, and postoperative hospital stay between the two groups was not significantly different. Frequency of additional NSAID use between the control group (2±4 suppositories) and pregabalin group (2±3 suppositories) was not significantly different (P=0.62). Numeric Rating Scale (NRS) for the intensity of ongoing pain, frequency of neuropathic pain, and Pain Catastrophizing Scale (PCS) between each group were not significantly different at any time until 3 months after surgery. Conclusions Early postoperative administration of pregabalin is not beneficial for patients with NSCLC. PMID:28149551

    Abstract Background: Trial design neuroinflammation and postoperative pain after surgery are increasingly reported in association with postoperative cognitive dysfunction (POCD). Parecoxib, a selective cyclooxygenase (COX)-2 inhibitor, is used for postoperative analgesia for its potent anti-inflammatory and analgesic effects. This study aimed to evaluate parecoxib's effects on POCD in elderly patients undergoing total knee arthroplasty. Methods: Around 134 elderly patients undergoing total knee arthroplasty were randomly divided into parecoxib (group P) and control (group C) groups, and treated with parecoxib sodium and saline, respectively, shortly after induction of general anesthesia and 12-h postsurgery, respectively. Perioperative plasma IL-1β, IL-6, TNF-α, and C-reactive protein (CRP) 1evels were measured. Postoperative pain was assessed following surgery. Neuropsychological tests were performed before surgery, and 1 week and 3 months postoperation. Results: POCD incidence in group P was significantly lower compared with that of group C at 1 week after surgery (16.7% vs 33.9%; P < 0.05); no significant difference was found between groups C and P at 3-month follow-up (9.7% vs 6.7%). Compared with group C values, visual analog pain scale (VAS) scores at 3, 6, and 12 hours after surgery were significantly lower in group P(P < 0.05). Plasma IL-1β, IL-6, and TNF-α levels were lower in group P than in group C after the operation (P < 0.05). No significant difference in the plasma CRP level was found between groups P and C. Conclusions: Parecoxib sodium decreases POCD incidence after total knee arthroplasty in elderly patients and may explain how this drug suppresses inflammation and acute postoperative pain caused by surgical trauma.

    There were examined 47 children, operated on for tumors of abdominal cavity and retroperitoneal space. The opioid-induced hyperalgesia may occur in early postoperative period. The anesthesia conduction of m. transverses abdominis (TAP-block), using 0.375% bupivacaine solution and combined spinal epidural analgesia (CSEA) for postoperative anesthesia have promoted the hyperalgesia severity reduction. Hyperalgesia in early postoperative period was demonstrated by upgrading of the toll-like receptors (TLR-4) level in the blood. The TLR-4 expression increased in the blood was noted while application of a TAP-block and CSEA.

    The objective of this study was to determine the effects of age, sex, and type of surgery on postoperative pain trajectories derived in a clinical setting from pain assessments in the first 24 hours after surgery. This study is a retrospective cohort study using a large electronic medical records system to collect and analyze surgical case data. The sample population included adult patients undergoing nonambulatory nonobstetric surgery in a single institution over a 1-year period. Analyses of postoperative pain trajectories were performed using a linear mixed-effects model. Pain score observations (91,708) from 7293 patients were included in the statistical analysis. On average, the pain score decreased about 0.042 (95% confidence interval [CI]: -0.044 to -0.040) points on the numerical rating scale (NRS) per hour after surgery for the first 24 postoperative hours. The pain score reported by male patients was approximately 0.27 (95% CI: -0.380 to -0.168) NRS points lower than that reported by females. Pain scores significantly decreased over time in all age groups, with a slightly more rapid decrease for younger patients. Pain trajectories differed by anatomic location of surgery, ranging from -0.054 (95% CI: -0.062 to -0.046) NRS units per hour for integumentary and nervous surgery to -0.104 (95% CI: -0.110 to -0.098) NRS units per hour for digestive surgery, and a positive trajectory (0.02 [95% CI: 0.016 to 0.024] NRS units per hour) for musculoskeletal surgery. Our data support the important role of time after surgery in considering the influence of biopsychosocial and clinical factors on acute postoperative pain.

    Dengue is an arbovirosis that ranges from an asymptomatic presentation to a more severe disease, which is characterized by a vascular leakage syndrome where abdominal pain is a major symptom. Transplant recipients are immunosuppressed and are less likely to develop a severe form of the disease because of a reduction in immune-mediated responses that trigger plasma extravasation events. Herein, we report two cases of severe dengue in the early postoperative period of two kidney transplant recipients. Considering the severity of the cases, we emphasize the importance of dengue screening immediately before transplantation in areas endemic for the disease.

    Percutaneous transluminal angioplasty has been successfully used for the treatment of transplant renal artery stenosis (RAS). Cutting-balloon angioplasty (CBA) is being used as a second option in pressure-resistant stenosis. It is thought that CBA is less traumatic and therefore restenosis occurs less frequently than in conventional angioplasty. This case report describes the unusual use of a cutting balloon in transplant RAS as a first option in the early postoperative period. Long-term follow-up data are also presented.

    2010-01-01

    Background: Magnetic resonance myelography (MRM) after lumbar discectomy is all too often an unrewarding challenge. A constellation of findings are inevitable, and determining their significance is often difficult. MRM is a noninvasive technique that can provide anatomical information about the subarachnoid space. Until now, there is no study reported in literature showing any clinico-radiological correlation of post operative MRM. The objective of this study was to prospectively evaluate the diagnostic effectiveness of MRM for the demonstration of decompression in operated discectomy patients and its correlation with subjective and objective outcome (pain and SLR) in immediate postoperative period. Materials and Methods: Fifty three patients of single level lumbar disc herniation (LDH) justifying the inclusion criteria were operated for discectomy. All patients underwent MRM on second/third postoperative day. The pain relief and straight leg raise sign improvement was correlated with the postoperative MRM images to group the patients into: A- Subjective Pain relief, SLR improved and MRM image showing myelo regression; B- Subjective Pain relief, SLR improved and MRM image showing no myelo regression; C- No Subjective Pain relief, no SLR improved and MRM image showing myelo regression and; D- No Subjective Pain relief, no SLR improved and MRM image showing no myelo regression. Results: The result showed that Group A had 46 while Group B, C and Group D had 4, 2 and one patients respectively. Clinico-radiological correlation (Clinically diagnosed patient and findings with MRM correlation) was present in 47 patients (88.68%) which includes both A and D groups. The MRM specificity and sensitivity were 92% and 33.33% respectively. Conclusion: MRM is a non-invasive, efficient and reliable tool in confirming postoperative decompression in lumbar discectomy patients, especially when economic factors are to be considered and the required expertise to reliably read a complex

    Both low serum uric acid (UA) levels and apathy are considered biomarkers of cognitive decline and dementia in Parkinson's disease (PD). There is an urgent need to combine different biomarkers to predict disease course in PD. Data on the relationship between serum UA levels and apathy in PD are lacking. The aim of this study is to evaluate the relationship between serum UA levels and pure apathy in early, drug-naïve PD patients. Forty-nine early, drug-naïve PD patients were enrolled and stratified into two groups using the median serum UA levels at diagnosis (Group 1 serum UA ≤ 4.8 mg/dl; Group 2 serum UA > 4.8 mg/dl). The cohort was followed for the first 2 years of disease. Apathy was evaluated with the Apathy Evaluation Scale (AES). Patients with lower serum UA levels presented significant higher AES score compared to patients with higher serum UA levels. Regression analysis showed that baseline serum UA levels were significant determinants of AES scores at both baseline and 2-year follow up, irrespective of gender, age, attention/executive functions and dopamine replacement therapy when applicable. This is the first study showing a link between serum UA levels and apathy in non-demented, non-depressed, early, drug-naïve PD, being lower serum UA levels associated with greater apathy. Further follow up of our patients and replication of this observation in independent cohorts are needed to establish if this combination of biomarkers may help in characterizing a subgroup of PD patients at diagnosis.

    Modified Early Warning Scores (MEWS) provide real-time vital sign (VS) trending and reduce ICU admissions in post-operative patients. These early warning calculations classically incorporate oxygen saturation, heart rate, respiratory rate, systolic blood pressure, and temperature but have not previously included end-tidal CO2 (EtCO2), more recently identified as an independent predictor of critical illness. These systems may be subject to failure when physiologic data is incorrectly measured, leading to false alarms and increased workload. This study investigates whether the implementation of automated devices that utilize ongoing vital signs monitoring and MEWS calculations, inclusive of a score for end-tidal CO2 (EtCO2), can be feasibly implemented on the general care hospital floor and effectively identify derangements in a post-operative patient's condition while limiting the amount of false alarms that would serve to increase provider workload. From July to November 2014, post-operative patients meeting the inclusion criteria (BMI > 30 kg/m(2), history of obstructive sleep apnea, or the use of patient-controlled analgesia (PCA) or epidural narcotics) were monitored using automated devices that record minute-by-minute VS included in classic MEWS calculations as well as EtCO2. Automated messages via pagers were sent to providers for instances when the device measured elevated MEWS, abnormal EtCO2, and oxygen desaturations below 85 %. Data, including alarm and message details from the first 133 patients, were recorded and analyzed. Overall, 3.3 alarms and pages sounded per hour of monitoring. Device-only alarms sounded 2.7 times per hour-21 % were technical alarms. The remaining device-only alarms for concerning VS sounded 2.0/h, 70 % for falsely recorded VS. Pages for abnormal EtCO2 sounded 0.4/h (82 % false recordings) while pages for low blood oxygen saturation sounded 0.1/h (55 % false alarms). 143 times (0.1 pages/h) the devices calculated a MEWS

    Gastrointestinal myoelectrical activity was registered in 6 dogs after different surgical procedures such as laparotomy, segmental resection of the jejunum and right hemicolectomy. Animals were studied in the fasted- and fed state and after pharmacological stimulation with Ceruletide. The electrical activity was recorded by means of 6 bipolar electrodes implanted along the intestinal wall. Abdominal surgery abolished normal motility in the stomach and small intestine only for a short period of time. The time for the reappearance of regularly recurring activity fronts varied with the type of the surgical procedure from 3 h after segmental resection of the jejunum to 49 h after colon resection. Severe disturbances of the BER (basic electrical rhythm) in the stomach as tachygastria and tachyarrhythmia persist even after restoration of the MMC (migrating motor complex) in the small intestine. Feeding induced a typical fedpattern but never before restoration of the MMC. Stimulation of the intestine during postoperative ileus with Ceruletide increases segmental myoelectrical activity. The period of postoperative ileus was not reduced.

    Background/Objectives: Effects of vitamin D deficiency in pregnancy have been associated with some adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in childbearing aged women and pregnancy loss (PL) in the first trimester. Subjects/Methods: This is a cross-sectional study. Plasma was collected from 60 nulliparous women with singleton at 7–9 weeks of gestation (30 with viable gestation and 30 with PL) and 60 non-gravid childbearing aged women (30 with a successful pregnancy history, and 30 with one or more spontaneous first-trimester PL history). Quantitation of serum 25-hydroxyvitamin D (25(OH)D) and 25-hydroxyvitamin D-1 alpha hydroxylase (CYP27B1) was assayed. Results: By pregnancy/non-gravid, normal pregnant women had higher 25(OH)D (49.32 μg/l) and CYP27B1 (82.00 pg/ml) than PL women (34.49 μg/l and 37.87 pg/ml, both P<0.01); the non-gravid women with a successful pregnancy history also had higher 25(OH)D (39.56 μg/l) and CYP27B1 (39.04 pg/ml) than women with PL history (12.30 μg/l and 12.35 pg/ml, both P<0.01). The 96.7% of non-gravid women with PL history and 43.3% of PL women had serum 25(OH)D concentrations below 30 μg/l. There was a strong association between low vitamin D levels and PL (odds ratio 1.71; 95% confidence interval: 1.2–2.4, P<0.001). The regression analyses showed that PL was significantly inversely correlated with 25(OH)D (P<0.01) and CYP27B1 levels (P<0.01). Conclusions: Vitamin D deficiency associated with PL in the first trimester of pregnancy. Decreased serum vitamin D levels among childbearing aged women with the failed clinical pregnancies history may predispose to increased risk for PL. PMID:27222154

    Introduction Pituitary neoplasms are benign entities that require distinct diagnostic and treatment considerations. Recent advances in endoscopic transsphenoidal surgery have resulted in shorter lengths of stay (LOS). We implemented a postoperative day (POD) 1 discharge paradigm involving a multidisciplinary approach and detailed preoperative evaluation and review of both medical and socioeconomic factors. Methods The experience of a single neurosurgeon/ears, nose, throat (ENT) team was reviewed, generating a preliminary retrospective database of the first 30 patients who underwent resection of pituitary lesions under the POD 1 discharge paradigm. We assessed multiple axes from their preoperative, in-house, and postoperative care. Results There were 14 men and 16 women with an average age of 53.8 years (range: 27-76 years). There were 22 nonsecretory and 8 secretory tumors with average size of 2.80 cm (range: 1.3-5.0 cm). All 30 patients underwent preoperative ENT evaluation. Average LOS was 1.5 ± 0.7 days. A total of 18 of 30 patients were discharged on POD 1. The insurance status included 15 with public insurance such as emergency Medicaid and 15 with private insurance. Four patients had transient diabetes insipidus (DI); none had permanent DI. Overall, 28 of 30 patients received postoperative steroids. Factors that contributed to LOS > 1 day included public insurance status, two or more medical comorbidities, diabetes mellitus, transient panhypopituitarism, and DI. Conclusion The implementation of a POD 1 discharge plan for pituitary tumors is feasible and safe for elective patients. This implementation requires the establishment of a dedicated Pituitary Center model with experienced team members. The consistent limitation to early discharge was socioeconomic status. Efforts that incorporate the analysis of social disposition parameters with proper management of clinical sequelae are crucial to the maintenance of ideal LOS and optimal patient

    Objectives: With side effects of antibiotics taken into consideration, the necessity of antibiotic therapy after simple implant placement procedures is still a subject of debate and the existing literature on this topic is widely controversial. The aim of this study was to assess the effect of postoperative amoxicillin therapy on early colonization of peri-implant sulcus after implant placement. Materials and Methods: In this randomized controlled clinical trial, 20 patients requiring simple implant placement were randomly allocated to test or control groups and received postoperative amoxicillin or placebo, respectively. Microbiological samples were collected on day 0 and day 7. Mann Whitney and Wilcoxon signed rank tests were utilized to evaluate changes in colony count of identified bacterial species between the test and control groups, and between day 0 and day 7. Results: The decrease in the number of sensitive facultative species and the increase in the number of resistant anaerobes in amoxicillin group were statistically significant as compared to the placebo group (P=0.025 and P=0.005, respectively). The increase in the number of sensitive anaerobes in the placebo group as compared to amoxicillin group, and the decrease in the number of facultative Gram-positive cocci as compared to the placebo group were statistically significant (P=0.011 and P=0.035, respectively). Conclusions: Postoperative administration of amoxicillin resulted in an increase in the number of resistant anaerobes and a decrease in the number of sensitive facultative bacteria and facultative Gram-positive cocci, as compared to the placebo, but with no sign/symptom of infection in any group.

    The identification of prognostic factors in cutaneous melanoma allows choosing the most effective treatment, especially in group of patients with locoregional disease. Markers related to carcinogenesis and angiogenesis in particular have effect on the course of the disease. The aim of this study was to evaluate clinical utility of vascular endothelial growth factor (VEGF), matrix metalloproteinase 2 (MMP-2), MMP-9, tissue inhibitors of metalloproteinase 1 (TIMP-1), and YKL-40 in serum of melanoma patients at pathological stages I-III. We included 148 adult patients with melanoma. The median follow-up was 40 months. Disease recurrence was observed in 43 patients; 3-year disease-free survival (DFS) rate was 71.7%; 35 patients died; and the 3-year overall survival (OS) rate was 85%. Concentrations of VEGF, MMP-2, MMP-9, TIMP-1, and YKL-40 were measured by ELISA kits. VEGF, MMP-9, TIMP-1, and YKL-40 were significantly higher in group of patients than in controls. Increased concentrations of TIMP-1 were related to patient survival, which in the group of lower and increased TIMP-1, disease-free survival amounted to 81 vs. 61% (p = 0.014) and overall survival -88 vs. 82% (p = 0.050), respectively. An increased concentration of YKL-40 was observed in 59% of patients with ulceration and in 26% of patients without ulceration (p = 0.012). We have found a clinically significant correlation between YKL-40 and MMP-9 (rho = 0.363; p = 0.004) as well as YKL-40 and VEGF (rho = 0.306; p = 0.018). In melanoma patients at stages I-III, the high concentrations of TIMP-1 in serum predicted adverse prognosis. YKL-40 was associated with ulceration of primary tumor, which is a very important prognostic factor.

    PN is a secreted cell adhesion protein critical for carcinogenesis. Elevated serum levels of PN have been implicated as playing an important role in different types of cancer, and a few reports suggest a potential role as a prognostic marker. We evaluated the prognostic significance of preoperative serum PN concentration in patients with BCa receiving curative surgery. Enzyme-Linked Immunosorbent Assay (ELISA) was performed to determine the preoperative serum PN level in 182 patients. The correlations between serum PN concentration with clinical pathological features and PN expression in primary tumor samples were analyzed. The prognostic impact of serum PN levels with all-cause and BCa-specific mortality was also investigated. Appropriate statistics were used. Elevated serum PN levels were significantly associated with patient age (p = 0.005), adjuvant systemic therapy (p = 0.04) and progesterone receptor (PgR) status (p = 0.02). No correlation between PN preoperative serum levels and other clinical-pathological parameters, including either the epithelial or the stromal PN expression of primary tumor or the combination of the two, was found. Similarly, no association between serum PN levels and either all-cause or BCa-specific mortality was found. However, subgroup analysis revealed a correlation between higher PN serum levels and all-cause mortality in patients with node-negative disease (p = 0.05) and in those with a low PgR expression (p = 0.03). Higher levels of serum PN were also found to correlate with BCa-specific mortality in the subgroup of patients who did not receive any adjuvant systemic therapy (p = 0.04). Our findings suggest that PN was detectable in the serum of early BCa patients before surgery and increased base-line serum levels predicted worse long-term survival outcomes in specific subgroups of patients.

    Molecular markers define the diagnosis of glioblastoma in the new WHO classification of 2016, challenging neuro-oncology centers to provide timely treatment initiation. The aim of this study was to determine whether a time delay to treatment initiation was accompanied by signs of early tumor progression in an MRI before the start of radiotherapy, and, if so, whether this influences the survival of glioblastoma patients. Images from 61 patients with early post-surgery MRI and a second MRI just before the start of radiotherapy were examined retrospectively for signs of early tumor progression. Survival information was analyzed using the Kaplan-Meier method, and a Cox multivariate analysis was performed to identify independent variables for survival prediction. 59 percent of patients showed signs of early tumor progression after a mean time of 24.1 days from the early post-surgery MRI to the start of radiotherapy. Compared to the group without signs of early tumor progression, which had a mean time of 23.3 days (p = 0.685, Student's t test), progression free survival was reduced from 320 to 185 days (HR 2.3; CI 95% 1.3-4.0; p = 0.0042, log-rank test) and overall survival from 778 to 329 days (HR 2.9; CI 95% 1.6-5.1; p = 0.0005). A multivariate Cox regression analysis revealed that the Karnofsky performance score, O-6-methylguanine-DNA-methyltransferase (MGMT) promoter methylation, and signs of early tumor progression are prognostic markers of overall survival. Early tumor progression at the start of radiotherapy is associated with a worse prognosis for glioblastoma patients. A standardized baseline MRI might allow for better patient stratification.

    Plantar fasciotomy is offered to patients with recalcitrant plantar fasciitis. Few studies have characterized the functional outcomes over time for the endoscopic approach compared with the open approach. We hypothesized that patients undergoing endoscopic surgery will have better postoperative functional outcomes early in the postoperative period but equivalent long-term outcomes compared with patients undergoing open surgery. We analyzed the prospectively collected data of all patients undergoing plantar fasciotomy at our institution from December 2007 to August 2014. A total of 42 feet of 38 patients were included in the analysis. The clinical data were collected preoperatively and at 3 and 6 months and 1 year. The functional outcomes analyzed included the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, the Medical Outcomes Study, Short-Form, 36-item Health Survey, and patient satisfaction and expectations. Patients undergoing endoscopic surgery had significantly greater American Orthopaedic Foot and Ankle Society Ankle-Hindfoot and SF-36 Health Survey scores and lower pain scores at the 3-month period. They were also significantly more likely to be satisfied with and have had their expectations met by surgery. Compared with the open approach, the patients who had undergone endoscopic plantar fasciotomy experienced significantly greater improvements in the subjective and objective functional outcomes, with less pain and greater satisfaction, and had had their expectations met earlier in the recovery period, with equivalent long-term outcomes, compared with the patients who had undergone open plantar fasciotomy.

    Early post-operative neurological deterioration is a well-known complication following dorsal cervical laminectomies and hemilaminectomies in dogs. This study aimed to evaluate potential risk factors for early post-operative neurological deterioration following these surgical procedures. Medical records of 100 dogs that had undergone a cervical dorsal laminectomy or hemilaminectomy between 2002 and 2014 were assessed retrospectively. Assessed variables included signalment, bodyweight, duration of clinical signs, neurological status before surgery, diagnosis, surgical site, type and extent of surgery and duration of procedure. Outcome measures were neurological status immediately following surgery and duration of hospitalisation. Univariate statistical analysis was performed to identify variables to be included in a multivariate model. Diagnoses included osseous associated cervical spondylomyelopathy (OACSM; n = 41), acute intervertebral disk extrusion (IVDE; 31), meningioma (11), spinal arachnoid diverticulum (10) and vertebral arch anomalies (7). Overall 54% (95% CI 45.25-64.75) of dogs were neurologically worse 48 h post-operatively. Multivariate statistical analysis identified four factors significantly related to early post-operative neurological outcome. Diagnoses of OACSM or meningioma were considered the strongest variables to predict early post-operative neurological deterioration, followed by higher (more severely affected) neurological grade before surgery and longer surgery time. This information can aid in the management of expectations of clinical staff and owners with dogs undergoing these surgical procedures.

    Peritoneal spread of tumors is a major problem in cancer management. Patients develop a marked deterioration in quality of life and shortened survival. This is in part due to bowel obstructions, marked ascites, and overall increase debilitation. Standard medical management has shown to be inadequate for the treatment of these problems. Surgery can palliate symptoms, however, it is unable to be complete at the microscopic level by a significant spillage of tumor cells throughout the abdomen. Chemotherapy can have some improvement in symptoms however it is short lived due to poor penetration into the peritoneal cavity. The role of intraperitoneal chemotherapy is to maximize tumor penetration and optimize cell death while minimizing systemic toxicity. Hyperthermic intraperitoneal chemotherapy (HIPEC) and early post-operative intraperitoneal chemotherapy (EPIC) are two treatment methods that serve this role and have been shown to improve survival. This review will discuss different chemotherapies used for both of these treatment options. PMID:26941983

    The optimal timing of early oral intake after surgery has not been fully established. The objective of this study was to compare early oral intake at postoperative day 1 after resection of colorectal cancer with that of day 2 to identify the optimal timing for resumption of oral intake in such patients. Consecutive patients with colorectal cancer who underwent elective colorectal resection were separated into two groups. Sixty-two patients began a liquid diet on the first postoperative day (POD1 group) and 58 patients began on POD2 (POD2 group) and advanced to a regular diet within the next 24 hours as tolerated. As for gastrointestinal recovery, the first passage of flatus was experienced, on average, on postoperative day 3.1 ± 1.0 in the POD2 group and on day 2.3 ± 0.7 in the POD1 group. The first defecation was also significantly earlier in patients in the POD1 group than those in the POD2 group (POD 3.2 ± 1.2 versus 4.2 ± 1.4, respectively). No statistical difference was found between the two groups in terms of postoperative complications. Our results suggest that very early feeding on POD1 after colorectal resection is safe and feasible and that induced a quicker recovery of postoperative gastrointestinal movement in patients.

    The purpose of our study was to determine the safety and tolerability of early oral hydration (EOH) compared with delayed oral hydration (DOH) after general anesthesia. One thousand anesthesiology (ASA) I to III adult patients undergoing non-gastrointestinal surgery with general anesthesia were randomized assigned into two groups: DOH (n=500, patients were given water 4 h after general anesthesia), EOH (n=500, patients were given 0.5 ml/kg water once recovered from general anesthesia.) in the postanesthesia care unit (PACU). Patients were evaluated for nausea, vomiting, drink desire, thirsty scale, oropharyngeal discomfort scale, and satisfaction scale. Statistical analysis was performed with Student’s t and Chi-Square tests. Complete data were available for 983 patients (EOH=488, DOH=495). Twenty minutes after receiving water the incidence of vomiting in EOH group was very low. And there was no significant difference between the two groups at the same time point (p > 0.05). Compared with DOH group, after receiving water there was a significant decrease of patients’ thirsty scales (p < 0.0001) and oropharyngeal discomfort scales (p < 0.0001) in EOH group. Significantly more patients’ satisfaction were reported in EOH group (p < 0.001). No serious adverse effects were reported during the study period. For patients undergoing non-gastrointestinal surgery, early oral hydration after recovery from general anesthesia was safe, with lower thirsty scale and oropharyngeal discomfort scales, and higher satisfaction.

    This two-part meta-analysis combined data from eight prospective randomized trials designed to compare the nutritional efficacy of early enteral (TEN) and parenteral (TPN) nutrition in high-risk surgical patients. The combined data gave sufficient patient numbers (TEN, n = 118; TPN, n = 112) to adequately address whether route of substrate delivery affected septic complication incidence. Phase I (dropouts excluded) meta-analysis confirmed data homogeneity across study sites, that TEN and TPN groups were comparable, and that significantly fewer TEN patients experienced septic complications (TEN, 18%; TPN, 35%; p = 0.01). Phase II meta-analysis, an intent-to-treat analysis (dropouts included), confirmed that fewer TEN patients developed septic complications. Further breakdown by patient type showed that all trauma and blunt trauma subgroups had the most significant reduction in septic complications when fed enterally. In conclusion, this meta-analysis attests to the feasibility of early postoperative TEN in high-risk surgical patients and that these patients have reduced septic morbidity rates compared with those administered TPN.

    Thirty-six multiparous cows were assigned to a study to determine the effects of dietary Co supplementation during late gestation and early lactation on concentrations of Co in serum and liver, vitamin B12 concentrations in serum and milk, and milk yield. Nonlactating cows received diets containing 0.15, 0.89, or 1.71 mg/ kg of Co (dry matter basis) from 55 d before parturition, and lactating cows received diets containing 0.19, 0.57, or 0.93 mg/kg of Co (dry matter basis) from parturition through 120 d postpartum. Serum vitamin B12 concentrations declined sharply in all cows between 55 and 20 d prepartum. Dietary Co supplementation tended to cause an increase in the concentration of vitamin B12 in colostrum and milk. Cobalt intake did not affect concentrations of Co in liver or serum, but increased the Co concentration of milk (0.089, 0.120, and 0.130 microg of Co/mL) at 120 days in milk. There was no effect of Co supplementation on dry matter intake or yield of milk and milk components. In conclusion, serum concentrations of vitamin B12 are reduced in the early dry period, and added dietary Co may increase ruminal synthesis of vitamin B12 as indicated by a tendency for increased vitamin B12 concentrations in colostrum and milk of cows supplemented with dietary Co.

    Objective To investigate the impact of postoperative adjuvant therapy on survival of patients with intermediate risk early-stage cervical squamous cell carcinoma. Methods A total of 133 consecutive patients with intermediate risk early-stage cervical squamous cell carcinoma treated at Shandong Cancer Hospital and Institute from February 2010 to March 2014 were enrolled in our study. All patients received adjuvant therapy and were subdivided into three groups: pelvic radiotherapy (RT; N=42), adjuvant chemotherapy + intracavitary radiotherapy (CT+ICRT; N=47), or concurrent chemoradiation (CCRT; N=44). Disease-free survival (DFS) and therapeutic complications were evaluated. Results There were no significant differences in DFS for patients treated with RT, CT+ICRT, and CCRT (P>0.05) with 3-year rates of 94.0%, 93.4%, and 97.6%, respectively. Frequencies of grade III–IV acute toxicities were higher in patients treated with CCRT (34.1%) than those treated with RT (9.5%) or CT+ICRT (16.7%; P<0.05), with no significant differences observed between RT and CT+ICRT groups (P>0.05). Grade I–II late toxicities were higher in CCRT (25%), followed by RT (19.0%), and finally, the CT+ICRT group (4.3%; P<0.05); with no significant differences observed between CCRT and RT groups (P>0.05). Conclusion Treatment with CT+ICRT or RT resulted in the equivalent of 3-year DFS compared to CCRT, but fewer therapeutic complications were observed with CT for patients with intermediate risk early-stage cervical squamous cell carcinoma.

    Objective To identify serum biomarkers of early spontaneous preterm birth (SPTB) using semi-quantitative proteomic analyses. Study Design Nested case-control study of pregnant women with previous SPTB. Maternal serum was collected at 19 to 24 and 28 to 32 weeks gestation, and analyzed by liquid chromatography-multiple-reaction monitoring-mass spectrometry. Targeted and shotgun proteomics identified 31 candidate proteins that were differentially expressed in pooled serum samples from spontaneous preterm (<34 weeks - cases) and term deliveries (controls). Candidate protein expression was compared in individual serum samples between cases and controls matched by age and race groups, and clinical site. Protein expression was verified by Western blot in the placenta and fetal membranes from cases and controls. Results Serum samples were available for 35 cases and 35 controls at 19 to 24 weeks, and 16 cases and 16 controls at 28 to 32 weeks. One protein, serpin B7, yielded serum concentrations that differed between cases and controls. The mean concentration of serpin B7 at 28 to 32 weeks was 1.5-fold higher in women with subsequent preterm deliveries compared to controls; there was no difference at 19 to 24 weeks. Higher levels of serpin B7 at both gestational age windows were associated with a shorter interval to delivery, and higher levels of serpin B7 in samples from 28 to 32 weeks were associated with a lower gestational age at delivery. Western blotting identified serpin B7 protein in placenta, amnion, and chorion from cases and controls. Conclusion Targeted and shotgun serum proteomics analyses associated one protein, serpin B7, with early SPTB. Our results require validation in other cohorts and analysis of the possible mechanistic role of serpin B7 in parturition. PMID:24954659

    Study Design Case-control study. Purpose To identify the characteristics of candidate indexes for early detection of surgical site infection (SSI). Overview of Literature SSI is a serious complication of spinal instrumentation surgery. Early diagnosis and treatment are crucial for the welfare of the patient postoperation. Methods We retrospectively reviewed laboratory data of patients who underwent posterior lumbar instrumentation surgery for degenerative spine disease. The sensitivity and specificity of six laboratory markers for early detection of SSI were calculated: greater elevation of the white blood cell count at day 7 than at day 4 postoperatively, greater elevation of the C-reactive protein (CRP) level at day 7 than at day 4 postoperatively, a CRP level of >10 mg/dL at 4 days postoperatively, neutrophil percentage of >75% at 4 days postoperatively, a lymphocyte percentage of <10% at 4 days postoperatively, and a lymphocyte count of <1,000/µL at 4 days postoperatively. Statistical analysis was via Fisher's exact test and a p-value of <0.05 was considered significant. Results In total, 85 patients were enrolled. Of these, five patients developed deep SSI. The sensitivity and specificity of each index were as follows: index 1, 20.0% and 77.5%; index 2, 20.0% and 83.8%; index 3, 40.0% and 97.5%; index 4, 40.0% and 86.3%; index 5, 0% and 96.3%; and index 6, 80.0% and 80.0%. A significant difference was noted for indexes 3 and 6. Conclusions A CRP level of >10 mg/dL at 4 days postoperatively would be useful for definitive diagnosis of SSI, and a lymphocyte count of <1,000/µL at 4 days postoperatively would be a useful screening test for SSI. Although laboratory markers for early detection of SSI have been frequently reported, we believe that it is important to understand the characteristics of each index for a precise diagnosis.

    Early diagnosis is the key for the successful treatment of breast cancer. A serum marker for the early detection of breast cancer could significantly reduce breast cancer morbidity and mortality by bringing the time of diagnosis at an earlier and therefore still curable stage. So far, no biomarker for the early detection is available for the clinical routine. The aim of the present study was to evaluate the use of calponin-h2 as a blood-based biomarker for the early diagnosis of this disease. Using two monoclonal antibodies against calponin-h2, we developed a sandwich ELISA to analyze the serum levels of calponin-h2. In order to evaluate the diagnostic potential of this biomarker, patients with breast cancer (n = 76), benign diseases of the breast (n = 51) and healthy females (n = 24) were analyzed. Serum levels above 10 ng/ml were only observed in patients with breast cancer (n = 8; 10.5%). Further large-scale studies and preanalytic evaluations are necessary to clarify the definite role of calponin-h2 as a biomarker in breast cancer management.

    Background Tissue injuries may provoke neuro-hormonal response which in turn may lead to release of inflammatory cytokines. We hypothesize that block of afferent sensory pathways by infiltration of 0.5% bupivacaine in the scalp may decrease neuro-hormonal response in the neurosurgical patient. Methods After obtaining informed consent, forty ASA physical statuses I, II, or III patients between the ages of 18 and 65 years were enrolled randomly into two equal groups to receive either 20 ml of 0.5% bupivacaine (group A) or 20 ml of 0.9% normal saline as a placebo (group B) in the site of pin insertion and scalp incision. As the primary outcome we checked serum C-reactive protein (CRP) levels before implementation of noxious stimulus, 24h, and 48h after the end of surgery to compare these values between groups. In addition, mean arterial pressure (MAP) and heart rate (HR) were checked at baseline (after the induction of anesthesia), one minute after pin fixation and 5, 10, and 15 minute after skin incision and the recorded values were compared between groups. Results No significant difference was found between serum CRP levels of the two groups. Comparison of mean HR between groups shows no significant difference. The mean of MAP was significantly lower in the group A in comparison with the group B (p< 0.001). Conclusion The results of this study confirm that 0.5% bupivacaine scalp infiltration before skull-pin holder fixation and skin incision could not decrease post-operative C-reactive protein level.

    Using a novel noninvasive, visible-light optical diffusion oximeter (T-Stat VLS Tissue Oximeter; Spectros Corporation, Portola Valley, CA) to measure the tissue oxygen saturation (StO2) of the buccal mucosa, the correlation between StOz and central venous oxygen saturation (ScvO2) was examined in children with congenital cyanotic heart disease undergoing a cardiac surgical procedure. Paired StO2 and serum ScvO2 measurements were obtained postoperatively and statistically analyzed for agreement and association. Thirteen children (nine male) participated in the study (age range, 4 days to 18 months). Surgeries included Glenn shunt procedures, Norwood procedures, unifocalization procedures with Blalock-Taussig shunt placement, a Kawashima/ Glenn shunt procedure, a Blalock-Taussig shunt placement, and a modified Norwood procedure. A total of 45 paired StO2-ScvO2 measurements was obtained. Linear regression demonstrated a Pearson's correlation of .58 (95% confidence interval [CI], .35-.75; p < .0001). The regression slope coefficient estimate was .95 (95% CI, .54-1.36) with an interclass correlation coefficient of .48 (95% CI, .22-.68). Below a clinically relevant average ScvO2 value, a receiver operator characteristic analysis yielded an area under the curve of .78. Statistical methods to control for repeatedly measuring the same subjects produced similar results. This study shows a moderate relationship and agreement between StO2 and ScvO2 measurements in pediatric patients with a history of congenital cyanotic heart disease undergoing a cardiac surgical procedure. This real-time monitoring device can act as a valuable adjunct to standard noninvasive monitoring in which serum SyvO2 sampling currently assists in the diagnosis of low cardiac output after pediatric cardiac surgery.

    Breast cancer is the most common cancer in women worldwide, identification of new biomarkers for early diagnosis and detection will improve the clinical outcome of breast cancer patients. In the present study, we determined serum levels of vitronectin (VN) in 93 breast cancer patients, 30 benign breast lesions, 9 precancerous lesions, and 30 healthy individuals by enzyme-linked immunosorbent assays. Serum VN level was significantly higher in patients with stage 0-I primary breast cancer than in healthy individuals, patients with benign breast lesion or precancerous lesions, as well as those with breast cancer of higher stages. Serum VN level was significantly and negatively correlated with tumor size, lymph node status, and clinical stage (p < 0.05 in all cases). In addition, VN displayed higher area under curve (AUC) value (0.73, 95 % confidence interval (CI) [0.62-0.84]) than carcinoembryonic antigen (CEA) (0.64, 95 % CI [0.52-0.77]) and cancer antigen 15-3 (CA 15-3) (0.69, 95 % CI [0.58-0.81]) when used to distinguish stage 0-I cancer and normal control. Importantly, the combined use of three biomarkers yielded an improvement in receiver operating characteristic curve with an AUC of 0.83, 95 % CI [0.74-0.92]. Taken together, our current study showed for the first time that serum VN is a promising biomarker for early diagnosis of breast cancer when combined with CEA and CA15-3.

    Previous studies have reported inconsistent associations between maternal serum ferritin concentrations and the risk of spontaneous preterm birth (sPTB). The aim of the present study was to examine the association between Fe biomarkers, including serum ferritin concentrations, and the risk of total ( 75th percentile ( ≥ 43 μg/l) (OR 1.49, 95% CI 1.06, 2.10) and >90th percentile ( ≥ 68 μg/l) (OR 1.92, 95% CI 1.25, 2.96). Increased odds of early and moderate-to-late sPTB were associated with ferritin levels >90th percentile (OR 2.50, 95% CI 1.32, 4.73) and >75th percentile (OR 1.56, 95% CI 1.03, 2.37), respectively. No association was found between the risk of sPTB and elevated sTfR levels or Fe deficiency. In conclusion, elevated maternal serum ferritin levels in early pregnancy are associated with an increased risk of sPTB from 34 weeks of gestation. The usefulness of early pregnancy ferritin levels in identifying women at risk of sPTB warrants further investigation.

    A 51-year-old Japanese man who underwent a standard distal gastrectomy for cancer of the stomach developed abdominal pain when oral intake was commenced on the 6th postoperative day after an uneventful postoperative course. Complete obstruction of the jejunum led to a sudden deterioration in his general condition and a laparotomy was performed, revealing counterclockwise rotation of the mesenterium. The necrotic portion of the small intestine was removed, while 10 cm of the upper jejunum and 100 cm of the terminal ileum were preserved. His second postoperative course was uneventful apart from the development of "intestinal hurry," which is now under medical control 9 months after his second laparotomy.

    Accidental radiation exposure is a threat to human health that necessitates effective clinical planning and diagnosis. Minimally invasive biomarkers that can predict long-term radiation injury are urgently needed for optimal management after a radiation accident. We have identified serum microRNA (miRNA) signatures that indicate long-term impact of total body irradiation (TBI) in mice when measured within 24 hours of exposure. Impact of TBI on the hematopoietic system was systematically assessed to determine a correlation of residual hematopoietic stem cells (HSCs) with increasing doses of radiation. Serum miRNA signatures distinguished untreated mice from animals exposed to radiation and correlated with the impact of radiation on HSCs. Mice exposed to sublethal (6.5 Gy) and lethal (8 Gy) doses of radiation were indistinguishable for 3 to 4 weeks after exposure. A serum miRNA signature detectable 24 hours after radiation exposure consistently segregated these two cohorts. Furthermore, using either a radioprotective agent before, or radiation mitigation after, lethal radiation, we determined that the serum miRNA signature correlated with the impact of radiation on animal health rather than the radiation dose. Last, using humanized mice that had been engrafted with human CD34+ HSCs, we determined that the serum miRNA signature indicated radiation-induced injury to the human bone marrow cells. Our data suggest that serum miRNAs can serve as functional dosimeters of radiation, representing a potential breakthrough in early assessment of radiation-induced hematopoietic damage and timely use of medical countermeasures to mitigate the long-term impact of radiation.

    Serum type III procollagen peptide (PIIIP) concentrations were determined in 36 male workers exposed to asbestos fibres in the production of asbestos cement items and in 13 healthy male controls. Mean (SD) PIIIP serum concentrations were 9.3 (1.5) ng/ml (range 7-12) in the controls and 13.7 (3.5)ng/ml (range 7.5-20) in the asbestos workers; the difference was statistically significant (p less than 0.01). The exposed workers were subdivided according to presence or absence of radiological signs of asbestosis and intensity and duration of exposure. PIIIP serum values of workers with asbestos related interstitial fibrosis were the highest of the groups at 14.6 (2.3) ng/ml. In workers with heavy exposure the PIIIP values were significantly related to duration of exposure (r = 0.95; p less than 0.01). PIIIP serum values may be a useful index for the early diagnosis of asbestos induced pulmonary fibrosis and its use should be considered as part of the biological monitoring of exposed workers.

    Many molecules fail to reach the market due to poor pharmacokinetic (PK) properties, rendering the potential drug virtually unavailable for the primary target despite efficient administration to the body. PK properties of endogenous and exogenous compounds in mammals are dependent, among other factors, on their ability to interact with serum proteins. The extent of binding can greatly influence their ADME (adsorption, distribution, metabolism and execration) profile. Reliable and cost-effective bioavailability studies, early in the drug discovery process, can lead to an improvement of the success rate for compounds entering clinical trials. Optical biosensors based on surface plasmon resonance (SPR) detection emerged as an efficient approach to obtain large amounts of information about the binding of small molecules to serum proteins. Simple, automated and fast assays provide a good throughput, versatility and highly informative data output, rendering the methodology particularly suited for early screening. The ability to provide basic information on PK can be easily coupled to structure-activity relationship analysis. In this review, features of the technology and its employment for the study of serum protein-small molecule interactions are presented and discussed.

    Overweight and obese patients are at especially high risk for delayed awakening after general surgery. Whether this risk also applies to cerebral neurosurgical procedures remains unclear. This study evaluated early postoperative cognitive recovery and gas exchange patterns, after balanced anesthesia with sevoflurane or desflurane, in overweight and obese patients undergoing craniotomy for supratentorial expanding lesions. Fifty-six patients were consecutively enrolled, and randomly assigned to 1 of 2 study groups to receive balanced anesthesia with sevoflurane or desflurane. Cognitive function was evaluated with the Short Orientation Memory Concentration Test and the Rancho Los Amigos Scale and gas exchange patterns (pH, PaO2, and PaCO2) were recorded in all patients at 5 time-points: preoperatively and postoperatively, after patients reached an Aldrete score >or=9, at 15, 30, 45, and 60 minutes. Preoperative cognitive status was similar in the 2 treatment groups. Early postoperative cognitive recovery was more delayed and Short Orientation Memory Concentration Test scores at 15 and 30 minutes postanesthesia were lower in patients receiving sevoflurane-based anesthesia than in those receiving desflurane-based anesthesia (21.5+/-3.5 vs. 14.9+/-3.5) (P<0.005) and (26.9+/-0.7 vs. 21.5+/-1.4) (P<0.005), and the postoperative Rancho Los Amigos Scalegrade 8 showed a similar trend (25/28 patients 89% vs. 8/28 patients 28% (P<0.005) and 28/28 patients (100% vs. 13/28 patients 46%) (P<0.005). Similarly, gas-exchange analysis showed higher PaCO2 at 15 and 30 minutes and lower pH up to 45 minutes postextubation in patients receiving sevoflurane-based anesthesia. In overweight and obese patients undergoing craniotomy desflurane-based anesthesia allows earlier postoperative cognitive recovery and reversal to normocapnia and normal pH.

    Liver transplantation with the use of donation after circulatory death (DCD) is associated with ischemic cholangiopathy (IC) often leading to graft loss. We hypothesized that serial postoperative analysis of alkaline phosphatase and bilirubin might identify patients who would later on develop ischemic cholangiopathy and/or graft loss, allowing early recognition and potentially retransplantation. The University of Washington DCD experience totals 89 DCD liver transplantations performed from 2003 to 2011 with Kaplan-Meier estimated 5-year patient and graft survival rates of 81.6% and 75.6%, respectively; 84/89 patients transplanted with DCD livers lived ≥ 60 days after transplantation and were analyzed. Serum bilirubin and alkaline phosphatase levels at 1 week, 2 week, 1 month, and 2 months after transplantation were analyzed. Two-month serum bilirubin and alkaline phosphatase proved to have the strongest associations with development of IC and graft failure. Two-month alkaline phosphatase of <100 U/L had a negative predictive value of 97% for development of IC. Two-month alkaline phosphatase demonstrated an inflection starting at >300 U/L strongly associated with development of IC (P < .0001). Serum bilirubin at 2 months was most strongly associated with graft failure within the 1st year with a strong inflection point at 2.5 mg/dL (P = .0001). All jaundiced recipients at 60 days after transplantation (bilirubin >2.5 mg/dL) developed graft failure within the 1st year (P < .0001). Use of these early surrogate markers could facilitate prioritization and early retransplantation for DCD liver recipients with allografts destined for failure.

    Objectives: To compare the effect of cataract surgery on anterior segment parameters measured by optical biometry in primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PXG). Materials and Methods: Twenty-five eyes of 25 patients with POAG and 29 eyes of 29 patients with PXG who had uncomplicated phacoemulsification and posterior chamber intraocular lens implantation surgery were included to our prospective study. Central corneal thickness (CCT), anterior chamber depth (ACD) and axial length (AL) were measured with an optical biometer preoperatively and at 1 month postoperatively. The pre- and postoperative values of intraocular pressure (IOP) and the anterior segment parameters and the differences between POAG and PXG were compared statistically by paired t, independent t and chi-square tests. Results: The mean values of preoperative CCT (p=0.042) and ACD (p=0.012) were significantly lower in the PXG than in the POAG group. In the PXG group, IOP decreased (p=0.001) but CCT (p=0.03) and ACD (p=0.001) increased significantly postoperatively; AL did not change significantly. In the POAG group, IOP decreased (p=0.01) and ACD (p=0.004) increased significantly postoperatively, while AL and CCT did not change significantly. There were no significant differences in the pre- to postoperative changes in IOP (p=0.76), AL (p=0.44) and CCT (p=0.52) values between the two groups. However, the postoperative increase in ACD was larger in the PXG group (p=0.03). Conclusion: Cataract surgery may cause some changes in IOP and anterior segment parameters like ACD and CCT postoperatively in eyes with POAG and PXG, and these changes may differ between eyes with PXG and POAG.

    We aimed to identify microRNA (miRNA) expression patterns in the serum of prostate cancer (CaP) patients that predict the risk of early treatment failure following radical prostatectomy (RP). Microarray and Q-RT-PCR analyses identified 43 miRNAs as differentiating disease stages within 14 prostate cell lines and reflectedpublically available patient data. 34 of these miRNA were detectable in the serum of CaP patients. Association with time to biochemical progression was examined in a cohort of CaP patients following RP. A greater than two-fold increase in hazard of biochemical progression associated with altered expression of miR-103, miR-125b and miR-222 (p <.0008) in the serum of CaP patients. Prediction models based on penalized regression analyses showed that the levels of the miRNAs and PSA together were better at detecting false positives than models without miRNAs, for similar level of sensitivity. Analyses of publically available data revealed significant and reciprocal relationships between changes in CpG methylation and miRNA expression patterns suggesting a role for CpG methylation to regulate miRNA. Exploratory validation supported roles for miR-222 and miR-125b to predict progression risk in CaP. The current study established that expression patterns of serum-detectable miRNAs taken at the time of RP are prognostic for men who are at risk of experiencing subsequent early biochemical progression. These non-invasive approaches could be used to augment treatment decisions. PMID:24583788

    Methamphetamine (METH) abuse is an increasing public health problem worldwide. Many of the METH-induced physical and mental problems are associated with the neurotoxic effects of METH. Animal studies have shown that brain-derived neurotrophic factor (BDNF) decreased after repeated amphetamine administration and increased at 30 and 90 days from psychostimulant withdrawal, suggesting that there might be a psychostimulant-induced neuroprotective dysfunction followed by a neuroadaptive process in the brain. However, current research on the role of BDNF in human METH addiction is limited, particularly during early withdrawal. The aim of this study was to assess the serum BDNF levels in METH abusers during the early withdrawal stage. Two groups of subjects were enrolled: (1) 59 DSM-IV METH abusers confirmed by board-certified psychiatrists during the first 3 weeks of withdrawal; (2) 59 age- and sex-matched healthy controls. We found that serum BDNF levels were significantly and constantly lower in the METH abusers during early withdrawal than those of the healthy controls. This indicates that METH abusers might have severe BDNF dysfunction and an impaired neuroprotective function after repetitive METH misuse.

    THE AIM OF THE STUDY was comparison of inflammatory response intensity through estimation of CRP, IL-6 and WBC concentration in blood serum in patients before and after inguinal hernia operations with Stoppa and TEP method. MATERIAL AND METHODS. The study involoved 117 patients operated on inguinal hernia between 2006-2008. The patients were divided into two groups. In the first group (group I - 56) Stopp'a method was used, in the second (group II - 61) TEP method. The patients selection was coincidental. All examined patients were men between 25-75 years old (mean age 54.3). Moreover, the operation's time, state of postoperative wound, the average hospitalization time and intensity of pain were estimated. The observations were directed over two weeks after operation. RESULTS. The inflammatory response estimated with CRP, IL-6 concentration in blood serum was considerably higher in patients operated with Stoppa method. There wasn't observed a relevant difference in increase of white blood cells' concentration in both groups. Moreover, the patients operated on with TEP method experienced lower pain. In group, operated on with Stoppa method, 3 cases of wound healing complications were observed. The operation's time was considerably shorter in the first group. The hospitalization time, was considerably shorter in patients operated on with videoscopic method. CONCLUSIONS. The operation of inguinal hernia with TEP technique in comparison with Stopp'a method is connected with considerably lower inflammatory response of organism, what directly involve with postoperative pain abridgment and reduction of hospitalization time. Moreover it may have influence on frequency of postoperative complications related with wound healing.

    Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

    Inadequate pain relief after lower limb joint replacement surgery has been a well-recognised limiting factor affecting post-operative mobilisation and length of hospital stay. Multimodal local wound infiltration with local anaesthetics, adrenaline and non-steroidal anti-inflammatory agents can lower the opiate intake, reduce the length of stay and enhance early mobilisation in knee replacement patients. A retrospective review of 64 patients undergoing primary total knee replacement was undertaken. Thirty-two patients (cases) had their wounds infiltrated with ropivacaine, adrenaline and ketorolac by the operating surgeon, intraoperatively. Subsequently, a 19G wound catheter placed into the knee joint. They received two further top-up doses of the same combination at 10 and 20 h post-operatively. This group was compared with a control group of 32 patients who did not receive any local infiltration. Both groups were comparable in terms of BMI and age. Post-operative opiate drug consumption in first 48 h after surgery, length of hospital stays and time taken to mobilise after surgery were recorded. There was significant reduction in opiate consumption in the treatment group with an average consumption of 49.35 mg of morphine compared to 71.48 mg in the control group (p = 0.004). The median length of hospital stay was significantly reduced from 5 days in the control group to 4 days in the treatment group (p = 0.03). The patients in the treatment group mobilised around 19 h earlier (p = 0.001). No major post-operative complications were encountered in either group. Wound infiltration is an effective and safe technique that promotes early rehabilitation and discharge of patients following primary total knee replacement.

    Objective: To evaluate the effects of early enteral micro-feeding on neonatal serum vitamin D levels, and to analyze the application value of glutamine. Methods: One hundred ninty neonates enrolled in intensive care unit were randomly divided into a treatment group and a control group (n=95) that were both given enteral and parenteral nutrition support. Meanwhile, the treatment group was fed formula milk containing 0.3 g/(kg·d) glutamine as enteral nutrition support for 14 days. Results: The weight of the treatment group increased significantly faster than that of the control group did (P<0.05). The treatment group had significantly higher milk amount and calorie intake than those of the control group (P<0.05), and neonates in the treatment group who reached calorie intake of 50/80/100 kcal/kg/d were significantly younger (P<0.05). Meanwhile, the treatment group was significantly less prone to feeding intolerance than the control group (P<0.05). After 14 days of feeding, the serum motilin, gastrin and vitamin D levels of both groups all increased, with significant intra-group and inter-group differences. Such levels of the treatment group significantly exceeded those of the control group (P<0.05). Conclusion: Supplementing early enteral micro-feeding with glutamine promoted the absorption of neonatal routine nutrients and vitamin D, obviously regulated gastrointestinal hormones, and elevated weight as a result.

    In this study, we performed a proteomic analysis of sera from stage I gastric cancer patients using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) and established a diagnostic model for the early diagnosis of stage I gastric cancer. Serum samples from 169 gastric cancer patients and 83 age- and gender-matched healthy individuals were analyzed by SELDI-TOF-MS ProteinChip array technology. The SELDI-TOF-MS spectral data were analyzed using the Biomarker Wizard™ and Biomarker Patterns™ software to find differential proteins and develop a classification tree for gastric cancer. A total of 34 mass peaks were identified. Six peaks at a mass-to-charge ratio (m/z) of 2873, 3163, 4526, 5762, 6121 and 7778 were used to construct the diagnostic model. The model effectively distinguished gastric cancer samples from control samples, achieving a sensitivity and specificity of 93.49 and 91.57%, respectively. In addition, we identified 3 of the 6 protein peaks at 2873, 6121 and 7778 m/z, which distinguished between stage I and stage II/III/IV gastric cancer. The model had an accuracy of 88.89% for the identification of stage I gastric cancer. In conclusion, the diagnostic model for the detection of serum proteins by SELDI-TOF-MS ProteinChip array technology correctly distinguishes gastric cancer from healthy samples, and has the ability to screen and distinguish between early gastric cancer from advanced gastric cancer.

    Background: Modifiable behaviours during early childhood may provide opportunities to prevent disease processes before adverse outcomes occur. Our objective was to determine whether young children’s eating behaviours were associated with increased risk of cardiovascular disease in later life. Methods: In this cross-sectional study involving children aged 3–5 years recruited from 7 primary care practices in Toronto, Ontario, we assessed the relation between eating behaviours as assessed by the NutriSTEP (Nutritional Screening Tool for Every Preschooler) questionnaire (completed by parents) and serum levels of non–high-density lipoprotein (HDL) cholesterol, a surrogate marker of cardiovascular risk. We also assessed the relation between dietary intake and serum non-HDL cholesterol, and between eating behaviours and other laboratory indices of cardiovascular risk (low-density lipoprotein [LDL] cholesterol, apolipoprotein B, HDL cholesterol and apoliprotein A1). Results: A total of 1856 children were recruited from primary care practices in Toronto. Of these children, we included 1076 in our study for whom complete data and blood samples were available for analysis. The eating behaviours subscore of the NutriSTEP tool was significantly associated with serum non-HDL cholesterol (p = 0.03); for each unit increase in the eating behaviours subscore suggesting greater nutritional risk, we saw an increase of 0.02 mmol/L (95% confidence interval [CI] 0.002 to 0.05) in serum non-HDL cholesterol. The eating behaviours subscore was also associated with LDL cholesterol and apolipoprotein B, but not with HDL cholesterol or apolipoprotein A1. The dietary intake subscore was not associated with non-HDL cholesterol. Interpretation: Eating behaviours in preschool-aged children are important potentially modifiable determinants of cardiovascular risk and should be a focus for future studies of screening and behavioural interventions.

    Epithelial ovarian cancer (EOC) is the sixth most common cause of cancer deaths in women because the diagnosis occurs mostly when the disease is in its late-stage. Current diagnostic methods of EOC show only a moderate sensitivity, especially at an early-stage of the disease; hence, novel biomarkers are needed to improve the diagnosis. We recently reported that serum glycome modifications observed in late-stage EOC patients by MALDI-TOF-MS could be combined as a glycan score named GLYCOV that was calculated from the relative areas of the 11 N-glycan structures that were significantly modulated. Here, we evaluated the ability of GLYCOV to recognize early-stage EOC in a cohort of 73 individuals comprised of 20 early-stage primary serous EOC, 20 benign ovarian diseases (BOD), and 33 age-matched healthy controls. GLYCOV was able to recognize stage I EOC whereas CA125 values were statistically significant only for stage II EOC patients. In addition, GLYCOV was more sensitive and specific compared to CA125 in distinguishing early-stage EOC from BOD patients, which is of high relevance to clinicians as it is difficult for them to diagnose malignancy prior to operation.

    In the post-operative course of the interventions of lung resection for primary tumor, complications of different nature and severity can arise, recognizing different pathogenetic mechanisms and differing according to the type of resection performed and to the time elapsed after surgery. The low diagnostic accuracy of chest radiography requires a thorough knowledge of the radiologist about all radiographic findings, both normal and pathological, which can be found in the immediate post-operative period (within 30 days after surgery). This article aims to describe the incidence, the clinical features and the radiological aspects of immediate complications following pulmonary resections, with specific reference to those in which the diagnostic imaging provides a fundamental contribution.

    Surgical models in animals are used extensively to study small molecules and devices for lumbar intervertebral disc repair, replacement, and fusion. Although the ventral lumbar animal models themselves are well described, critical assessment of morbidity and mortality avoidance when using the models have not been reported. Hypothesizing that technique modifications and the relative prevalence and severity of complications would be correlated, we collected and examined peri- and postoperative data stratified by surgical technique. We here report complications associated with the transperitoneal approach to the lumbar spine in 268 Lewis rats and offer data-driven suggestions regarding complication avoidance through technique modification. Compared with wider exposure, limiting the width of exposure to a maximum of 3 mm resulted in fewer neurologic complications in the lower limbs. In addition, avoiding extracorporeal reflection of the small intestine during the exposure was associated with lower incidence of postoperative gastrointestinal distress and fewer situations requiring euthanasia. These findings underscore the importance of detailed approaches in minimizing postoperative morbidity and attrition in surgical models.

    Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by synovial inflammation and destruction of joint cartilage and bone. Different cytokines play important role in the processes that cause articular destruction and extra-articular manifestations in RA. The contribution of cytokines representing the Th1 (INF-γ), Th2 (IL-4) and IL-17A to the pathogenesis of early RA and bone mineral density (BMD) loss in still poorly understood. Serum samples of 38 early RA patients were evaluated for erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), C-reactive protein (CRP), anti-cyclic citrullinated peptide antibodies (anti-CCP) and for the tested cytokines (IL-17A, IL-4 and INF-γ). BMD was evaluated by dualenergy X-ray absorptiometry (DXA). Disease activity score (DAS28) calculation was assessed for all patients. Control serum samples were obtained from 34 healthy volunteers. The levels of tested cytokines were significantly higher (IL-17A, p<0.001; INF-γ, P<0.001; IL-4, P<0.01) in patients with early RA, compared to the healthy controls. In early RA patients, strong correlation of serum IL-17A was found with DAS28, ESR and CRP. Also, a significant negative correlation was found between serum INF-γ levels and the DAS28 score. Significantly positive correlation of BMD values and CRP, DAS28 IL-17A were also demonstrated. DXA analysis revealed that the most common site for osteoporosis was the lumbar spine followed by the femoral neck. BMD values significantly correlated with CRP, DAS28 score and IL-17A serum levels. The mean serum IL-17A levels, in patients with early RA, corresponded with disease activity, severity and BMD loss, indicating the potential usefulness of serum IL-17A in defining the disease activity and bone remodeling.

    The present study characterized the early changes in the serum chemokines/cytokine signatures and networks in infants with congenital-toxoplasmosis/(TOXO) as compared to non-infected-controls/(NI). TOXO were subgrouped according to the retinochoroidal lesion status as no-lesion/(NL), active-lesion/(ARL), active/cicatricial-lesion/(ACRL) and cicatricial-lesion/(CRL). The results showed that TOXO display prominent chemokine production mediated by IL-8/CXCL8, MIG/CXCL9, IP-10/CXCL10 and RANTES/CCL5. Additionally, TOXO is accompanied by mixed proinflammatory/regulatory cytokine pattern mediated by IL-6, IFN-γ, IL-4, IL-5 and IL-10. While TNF appears as a putative biomarker for NL and IFN-γ/IL-5 as immunological features for ARL, IL-10 emerges as a relevant mediator in ACRL/CRL. IL-8/CXCL8 and IP-10/CXCL10 are broad-spectrum indicators of ocular disease, whereas TNF is a NL biomarker, IFN-γ and MIG/CXCL9 point out to ARL; and IL-10 is highlighted as a genuine serum biomarker of ACRL/CRL. The network analysis demonstrated a broad chemokine/cytokine crosstalk with divergences in the molecular signatures in patients with different ocular lesions during congenital toxoplasmosis.

    Early detection of pancreatic cancer is promising for improving clinical outcome; however, no effective biomarker has yet been identified. Here, we detected 61 clinical serum parameters in 200 healthy controls (Ctrls), 163 pancreatic ductal adenocarcinoma (PDAC) patients and 109 benign pancreatitis patients (Benign) in the training group. A metropolis algorithm with Monte Carlo simulation was used for identifying parameter panels. Sera from 183 Ctrl, 129 PDAC and 95 Benign individuals were used for cross-validation. Samples from 77 breast, 72 cervical, 101 colorectal, 138 gastric, 108 prostate and 132 lung cancer patients were collected for evaluating cancer selectivity. A panel consisting of carbohydrate antigen (CA)19-9, albumin (ALB), C-reactive protein (CRP) and interleukin (IL)-8 had the highest diagnostic value for discriminating between PDAC and Ctrl. The sensitivity (SN) was 99.39% for all-stage, 96.10% for early-stage and 98.80% for advanced-stage PDAC at 90% specificity (SP). In the validation group, the sensitivities were 93.80, 93.10 and 94.40%, respectively, at 90% SP. This panel also identified 80.52% of the breast cancer, 66.67% cervical cancer, 86.14% colorectal cancer, 89.86% gastric cancer, 71.30% prostate cancer and 93.85% lung cancer samples as non-PDAC. The panel consisting of CA19-9, carbon dioxide, CRP and IL-6 panel had the highest diagnostic value for discriminating between PDAC and Benign. The SN was 74.23% for all-stage, 75.30% for early-stage and 74.40% for advanced-stage PDAC at 90% SP. In the validation group, the sensitivities were 72.10, 76.10 and 67.20%, respectively, at 90% SP. Our parameter panels may aid in the early detection of PDAC to improve clinical outcome.

  1. Identification of serum proteomic biomarkers for early porcine reproductive and respiratory syndrome (PRRS) infection

    2012-01-01

    Background Porcine reproductive and respiratory syndrome (PRRS) is one of the most significant swine diseases worldwide. Despite its relevance, serum biomarkers associated with early-onset viral infection, when clinical signs are not detectable and the disease is characterized by a weak anti-viral response and persistent infection, have not yet been identified. Surface-enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF MS) is a reproducible, accurate, and simple method for the identification of biomarker proteins related to disease in serum. This work describes the SELDI-TOF MS analyses of sera of 60 PRRSV-positive and 60 PRRSV-negative, as measured by PCR, asymptomatic Large White piglets at weaning. Sera with comparable and low content of hemoglobin (< 4.52 μg/mL) were fractionated in 6 different fractions by anion-exchange chromatography and protein profiles in the mass range 1–200 kDa were obtained with the CM10, IMAC30, and H50 surfaces. Results A total of 200 significant peaks (p < 0.05) were identified in the initial discovery phase of the study and 47 of them were confirmed in the validation phase. The majority of peaks (42) were up-regulated in PRRSV-positive piglets, while 5 were down-regulated. A panel of 14 discriminatory peaks identified in fraction 1 (pH = 9), on the surface CM10, and acquired at low focus mass provided a serum protein profile diagnostic pattern that enabled to discriminate between PRRSV-positive and -negative piglets with a sensitivity and specificity of 77% and 73%, respectively. Conclusions SELDI-TOF MS profiling of sera from PRRSV-positive and PRRSV-negative asymptomatic piglets provided a proteomic signature with large scale diagnostic potential for early identification of PRRSV infection in weaning piglets. Furthermore, SELDI-TOF protein markers represent a refined phenotype of PRRSV infection that might be useful for whole genome association studies. PMID:22873815

    Purpose To investigate the effects of early administration of dutasteride in patients with detectable serum prostate-specific antigen (PSA) levels after radical prostatectomy (RP). Materials and Methods A prospective open-label study, with a cumulative analysis of asymptomatic increase in PSA following RP, was conducted from January 2005 to December 2013. An early increase in PSA level was defined as detectable serum PSA level> 0.04 ng/mL. Patients with PSA level>0.04 ng/mL were treated with dutasteride 0.5 mg daily. Serum PSA level and biochemical recurrence (BCR) were monitored. We divided the patients into 2 groups based on the serum PSA response after dutasteride treatment. Results Eighty patients were included in the study. At the median follow-up of 51.8 months, 56 patients (70.0%) showed a decrease of greater than 10% in serum PSA level, and 24 showed increased PSA levels. Twelve of the 56 patients with PSA response showed subsequently increased PSA. Intergroup differences in preoperative PSA levels, PSA nadir levels, and Gleason score of 6 or less were significant (p=0.028, p=0.030, and p=0.035, respectively). A multivariate analysis revealed that Gleason score of 6 or less (p=0.018) and PSA nadir levels (p=0.011) were predictive factors for PSA response after early dutasteride treatment in men with increased PSA levels following RP. Conclusions Early monotherapy of dutasteride showed a decline in serum PSA levels in men with lower nadir PSA levels, and a Gleason score 6, when the serum PSA was detected after RP. PMID:28261678

    Highlights: Black-Right-Pointing-Pointer Overexpression of Ku86 in human liver cancer was shown by immunohistochemistry. Black-Right-Pointing-Pointer Serum anti-Ku86 was significantly elevated in early hepatocellular carcinoma. Black-Right-Pointing-Pointer Anti-Ku86 may be more sensitive than the conventional markers for early detection. Black-Right-Pointing-Pointer Serum anti-Ku86 significantly decreased after surgical resection of liver tumors. Black-Right-Pointing-Pointer Elevation of serum anti-Ku86 in other non-liver solid tumors was minimal. -- Abstract: Hepatocellular carcinoma (HCC), the predominant form of primary liver cancer, is one of the most common cancers worldwide and the third most common cause of cancer-related death. Imaging studies including ultrasound and computed tomography are recommended for early detection of HCC, but they are operator dependent, costly and involve radiation. Therefore, there is a need for simple and sensitive serum markers for the early detection of hepatocellular carcinoma (HCC). In our recent proteomic studies, a number of proteins overexpressed in HCC tissues were identified. We thought if the serum autoantibodies to these overexpressed proteins were detectable in HCC patients. Of these proteins, we focused on Ku86, a nuclear protein involved in multiple biological processes and aimed to assess the diagnostic value of serum anti-Ku86 in the early detection of HCC. Serum samples were obtained prior to treatment from 58 consecutive patients with early or relatively early hepatitis C virus (HCV)-related HCC and 137 patients with HCV-related liver cirrhosis without evidence of HCC. Enzyme immunoassays were used to measure serum levels of autoantibodies. Serum levels of anti-Ku86 antibodies were significantly elevated in HCC patients compared to those in liver cirrhosis patients (0.41 {+-} 0.28 vs. 0.18 {+-} 0.08 Abs at 450 nm, P < 0001). Setting the cut-off level to give 90% specificity, anti-Ku86 was positive in 60.7% of

    Antibodies against tumor-associated antigens have been found in serum of patients with various types of cancers and may serve as biomarkers for early detection of gastric cancer as well. This systematic review aims to give an overview about known autoantibodies and their diagnostic value in gastric cancer. We conducted a systematic literature search in two databases to identify studies which performed serological testing for autoantibodies in gastric cancer patients and controls. Data on study characteristics and results were extracted independently by two reviewers. Overall, 39 articles reporting the detection of 34 different autoantibodies met the inclusion criteria for this review. The most common antibody detection method was enzyme-linked immunosorbent assay and the most frequently assessed autoantibody was anti-p53, which was tested in 13 studies. Most antibodies were assessed in only one study and only few authors have evaluated the diagnostic value of combinations of multiple autoantibodies. For single autoantibodies, specificity was generally very high (median: 99.15%), but sensitivity was mostly rather low (median: 12.35%). For some autoantibody combinations, substantially higher sensitivity at reasonably high levels of specificity could be achieved. Development of extended and optimized multimarker panels of autoantibodies might be a promising approach for gastric cancer early detection.

    Background: Breast cancer is a leading cause of morbidity and mortality worldwide. Although mammography screening is available, there is an ongoing interest in improved early detection and prognosis. Herein, we have analysed a combination of serological biomarkers in a case–control cohort of sera taken before diagnosis. Methods: This nested case–control study within the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) used serum samples from 239 women who subsequently developed breast cancer and 239 matched cancer-free controls. Sera were screened by ELISA for 9 candidate markers. Univariate and multivariate analyses were performed to examine associations with clinico-pathological features and between case controls in different time groups before diagnosis. Results: Significant associations with clinico-pathological features related to prognosis were found for several candidates (CA15-3, HSP90A and PAI-1). However, there were no consistent differences between cases and controls for any candidate in the lead up to diagnosis. Whilst combination models outperformed single markers, there was no increase in performance towards diagnosis. Conclusions: This study using unique pre-diagnosis samples shows that CA15-3, HSP90A and PAI-1 have potential as early prognostic markers and warrant further investigation. However, none of the candidates or combinations would be useful for screening. PMID:28081538

    Objective Suitable biomarkers are essential for the design of therapeutic strategies in personalized medicine. Vasoactive intestinal peptide (VIP) has demonstrated immunomodulatory properties in autoimmune murine and ex vivo human models. Our aim was to study serum levels of VIP during the follow-up of an early arthritis (EA) cohort and to analyze its value as a biomarker predicting severity and therapeutic requirements. Methods Data from 91 patients on an EA register were analyzed (76% rheumatoid arthritis (RA), 24% undifferentiated arthritis, 73% women, and median age 54 years; median disease duration at entry, 5.4 months). We collected per protocol sociodemographic, clinical, and therapeutic data. VIP levels were determined by enzyme immunoassay in sera harvested from the 91 patients (353 visits; 3.9 visit/patient) and from 100 healthy controls. VIP values below the 25th percentile of those assessed in healthy population were considered low. To determine the effect of independent variables on VIP levels, we performed a longitudinal multivariate analysis nested by patient and visit. A multivariate ordered logistic regression was modeled to determine the effect of low VIP serum levels on disease activity at the end of follow-up. Results VIP concentrations varied considerably across EA patients. Those fulfilling the criteria for RA had the lowest values in the whole sample, although no significant differences were observed compared with healthy donors. Disease activity, which was assessed using DAS28, inversely correlated with VIP levels. After a two-year follow-up, those patients with low baseline levels of VIP displayed higher disease activity and received more intensive treatment. Conclusion Patients who are unable to up-regulate VIP seem to have a worse clinical course despite receiving more intense treatment. Therefore, measurement of VIP levels may be suitable as a prognostic biomarker. PMID:24409325

    Introduction: Opioids are widely used in conjunction with local anesthetics as they permit the use of lower dose of local anesthetics while providing adequate anesthesia and analgesia. It both provides adequate anesthesia as well as lower drug toxicity neuraxial administration of opioids in conjunction with local anesthetics improves the quality of intraoperative analgesia and prolongs the duration of postoperative analgesia. Bupivacaine is the most commonly used drug for subarachnoid block due to its lesser side effects. The present study was conducted to decrease the overall dose of local anesthetics with opioid combination for urological procedure with respect to quality of anesthesia and recovery with patient's satisfaction. Materials and Methods: The study population was randomly allocated by computer generated table into two groups; Group A: 5 mg 0.5% bupivacaine + 25 mcg and Group B: 5 mg 0.5% bupivacaine + 25 mg butorphanol. Results: Highest level of sensory block was T9 and T8 with the fentanyl group and butorphanol group, respectively. The onset of sensory block was early in fentanyl group than butorphanol group. Duration of both sensory and motor block was significantly higher in butorphanol group. There was no incidence of itching in both groups. There were two patients in fentanyl group and one in butorphanol with hypotension for which injection mephentermine was given. Two patients in fentanyl group complained of nausea and vomiting, for which injection ondansetron was given. One patient complained of pain in fentanyl group for which injection propofol with injection fentanyl was supplemented. Conclusion: Low-dose bupivacaine with butorphanol group was devoid of any side effects in the present study but low dose bupivacaine in addition with fentanyl is superior in terms of early postoperative recovery resulting in early discharge and better outcome in comparison to bupivacaine and butorphanol group, which is beneficial in elderly patients with

    Purpose: The purpose of this study was to evaluate dose-volume histogram (DVH) predictors for the development of chronic gastrointestinal (GI) complications in cervical cancer patients who underwent radical hysterectomy and postoperative concurrent nedaplatin-based chemoradiation therapy. Methods and Materials: This study analyzed 97 patients who underwent postoperative concurrent chemoradiation therapy. The organs at risk that were contoured were the small bowel loops, large bowel loop, and peritoneal cavity. DVH parameters subjected to analysis included the volumes of these organs receiving more than 15, 30, 40, and 45 Gy (V15-V45) and their mean dose. Associations between DVH parameters or clinical factors and the incidence of grade 2 or higher chronic GI complications were evaluated. Results: Of the clinical factors, smoking and low body mass index (BMI) (<22) were significantly associated with grade 2 or higher chronic GI complications. Also, patients with chronic GI complications had significantly greater V15-V45 volumes and higher mean dose of the small bowel loops compared with those without GI complications. In contrast, no parameters for the large bowel loop or peritoneal cavity were significantly associated with GI complications. Results of the receiver operating characteristics (ROC) curve analysis led to the conclusion that V15-V45 of the small bowel loops has high accuracy for prediction of GI complications. Among these parameters, V40 gave the highest area under the ROC curve. Finally, multivariate analysis was performed with V40 of the small bowel loops and 2 other clinical parameters that were judged to be potential risk factors for chronic GI complications: BMI and smoking. Of these 3 parameters, V40 of the small bowel loops and smoking emerged as independent predictors of chronic GI complications. Conclusions: DVH parameters of the small bowel loops may serve as predictors of grade 2 or higher chronic GI complications after postoperative

    Purpose: To determine the clinical benefit of high-dose early adjuvant radiotherapy (EART) in high-risk prostate cancer (hrCaP) patients submitted to radical retropubic prostatectomy plus pelvic lymphadenectomy. Patients and Methods: The clinical outcome of 334 hrCaP (pT3-4 and/or positive resection margins) node-negative patients submitted to radical retropubic prostatectomy plus pelvic lymphadenectomy before 2004 was analyzed according to the EART dose delivered to the prostatic bed, <70.2 Gy (lower dose, median 66.6 Gy, n = 153) or >=70.2 Gy (median 70.2 Gy, n = 181). Results: The two groups were comparable except for a significant difference in terms of median follow-up (10 vs. 7 years, respectively) owing to the gradual increase of EART doses over time. Nevertheless, median time to prostate-specific antigen (PSA) failure was almost identical, 38 and 36 months, respectively. At univariate analysis, both 5-year biochemical relapse-free survival (bRFS) and disease-free survival (DFS) were significantly higher (83% vs. 71% [p = 0.001] and 94% vs. 88% [p = 0.005], respectively) in the HD group. Multivariate analysis confirmed EART dose >=70 Gy to be independently related to both bRFS (hazard ratio 2.5, p = 0.04) and DFS (hazard ratio 3.6, p = 0.004). Similar results were obtained after the exclusion of patients receiving any androgen deprivation. After grouping the hormone-naive patients by postoperative PSA level the statistically significant impact of high-dose EART on both 5-year bRFS and DFS was maintained only for those with undetectable values, possibly owing to micrometastatic disease outside the irradiated area in case of detectable postoperative PSA values. Conclusion: This series provides strong support for the use of EART doses >=70 Gy after radical retropubic prostatectomy in hrCaP patients with undetectable postoperative PSA levels.

    Introduction: Since currently no sensitive and specific biomarkers for early detection of lung adenocarcinoma (AD) exist and the majority of AD patients are diagnosed at late stages of disease, the development of effective screening tests for early-stage lung AD is urgently needed. Serum microRNAs (miRNAs) have been documented as novel noninvasive biomarkers in tumor diagnosis; thus, we studied the profile of serum miRNA in AD patients in order to identify the differentially expressed miRNAs as potential biomarkers for early detection of AD. Patients and Methods: Serum samples were collected from 180 AD patients and 180 age- and sex-matched healthy controls. Serum miRNA profiling was performed by low-density array (LDA) using RNA extracted from blood samples of 20 patients and 20 controls. To validate the selected miRNAs, a stem-loop based RT-qPCR assay was used and serum samples from 160 patients and 160 controls were examined. Results: Profiling data showed 11 differentially expressed miRNAs in the serum samples from AD patients compared with the controls. Among them, 6 selected miRNAs in AD patients, including miR-103, miR-146a, miR-151, miR-21, miR-221, miR-222, and miR-223, were validated by RT-qPCR. In particular, the top three, miR-146a, miR-222, and miR-223, were confirmed to be significantly expressed in stage I/II AD patients compared with healthy controls. Conclusion: A panel of miRNAs with miR-146a, miR-222 and miR-223 could be used as potential noninvasive biomarkers for early detection of AD. PMID:28123597

    Background Interleukin-15 (IL-15) is thought to be involved in the physiopathological mechanisms of RA and it can be detected in the serum and the synovial fluid of inflamed joints in patients with RA but not in patients with osteoarthritis or other inflammatory joint diseases. Therefore, the objective of this work is to analyse whether serum IL-15 (sIL-15) levels serve as a biomarker of disease severity in patients with early arthritis (EA). Methodology and Results Data from 190 patients in an EA register were analysed (77.2% female; median age 53 years; 6-month median disease duration at entry). Clinical and treatment information was recorded systematically, especially the prescription of disease modifying anti-rheumatic drugs. Two multivariate longitudinal analyses were performed with different dependent variables: 1) DAS28 and 2) a variable reflecting intensive treatment. Both included sIL-15 as predictive variable and other variables associated with disease severity, including rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibodies (ACPA). Of the 171 patients (638 visits analysed) completing the follow-up, 71% suffered rheumatoid arthritis and 29% were considered as undifferentiated arthritis. Elevated sIL-15 was detected in 29% of this population and this biomarker did not overlap extensively with RF or ACPA. High sIL-15 levels (β Coefficient [95% confidence interval]: 0.12 [0.06–0.18]; p<0.001) or ACPA (0.34 [0.01–0.67]; p = 0.044) were significantly and independently associated with a higher DAS28 during follow-up, after adjusting for confounding variables such as gender, age and treatment. In addition, those patients with elevated sIL-15 had a significantly higher risk of receiving intensive treatment (RR 1.78, 95% confidence interval 1.18–2.7; p = 0.007). Conclusions Patients with EA displaying high baseline sIL-15 suffered a more severe disease and received more intensive treatment. Thus, sIL-15 may be a biomarker for

    Magnesium-deficient patients show dysfunctional calcium (Ca(2+)) metabolism due to defective parathyroid hormone (PTH) secretion. In mice and rats, long-term magnesium (Mg(2+)) deprivation causes hyperphosphaturia and increases fibroblast growth factor 23 (FGF23) secretion, despite normal serum phosphate (Pi) and Ca(2+). Electrolyte disturbances during early hypomagnesemia may explain the response of mice to long-term Mg(2+) deprivation, but our knowledge of electrolyte homeostasis during this stage is limited. This study compares the effect of both short- and long-term Mg(2+) restriction on the electrolyte balance in mice. Mice were fed control or Mg(2+)-deficient diets for one to three days, one week, or three weeks. Prior to killing the mice, urine was collected over 24 h using metabolic cages. Within 24 h of Mg(2+) deprivation, hypomagnesemia, hypocalcemia and hyperphosphatemia developed, and after three days of Mg(2+) deprivation, serum potassium (K(+)) was increased. These changes were accompanied by a reduction in urinary volume, hyperphosphaturia, hypocalciuria and decreased Mg(2+), sodium (Na(+)) and K(+) excretion. Surprisingly, after one week of Mg(2+) deprivation, serum K(+), Pi and Ca(2+) had normalized, showing that mineral homeostasis is most affected during early hypomagnesemia. Serum Pi and K(+) are known to stimulate secretion of FGF23 and aldosterone, which are usually elevated during Mg(2+) deficiency. Thus, the hyperphosphatemia and increased serum K(+) concentration observed during short-term Mg(2+) deprivation may help our understanding of adaptation to chronic Mg(2+) deficiency.

    Pain thresholds and levels of distress before and in the early postoperative period after anterior cruciate ligament surgery were measured in professional and amateur male soccer players and compared. Between June 2005 and March 2007, 30 soccer players (10 amateur, 20 professional) with acute or chronic tears of the anterior cruciate ligament who were scheduled for a bone-tendon-bone ACL reconstruction procedure were enrolled in the study. Measures of pain intensity, depression and anxiety were assessed 1 day pre-operation and 1 week and 3 weeks post-operation (T1 T2 and T3). Pain was assessed using a visual analog scale (VAS), depression with the Beck Depression Inventory (BDI), and anxiety with both the state and trait forms of the State-Trait Anxiety Inventory (STAI). Scores on the VAS, BDI, and STAI in both groups were analyzed. The mean VAS scores at T1 and T2 in professional players were not significantly higher than those in amateur players (P>0.05). Professionals had significantly higher BDI scores at T1 and T2 (P<0.05), but this difference was not significant at T3 (P=0.12). High depression scores did not correlate with high pain scores. Pain scores between professional and amateur soccer players with ACL injuries were not significantly different pre-op or in the early post-op period. Depression was more common in professionals before and after their ACL surgery, but anxiety levels were not significantly different between the two groups.

    Objective This study was conducted to investigate survival related factors, as well as to evaluate the effects of early decompression on acute subdural hematoma (ASDH). Methods We retrospectively reviewed cases of decompressive craniectomy (DC) for decade. In total, 198 cases of DC involved ASDH were available for review, and 65 cases were excluded due to missing data on onset time and a delayed operation after closed observation with medical care. Finally, 133 cases of DC with ASDH were included in this study, and various factors including the time interval between trauma onset and operation were evaluated. Results In the present study, survival rate after DC in patients with ASDH was shown to be related to patient age (50 years old, p=0.012), brain compression ratio (p=0.042) and brain stem compression (p=0.020). Sex, preoperative mental status, and time interval between trauma onset and operation were not related with survival rate. Among those that survived (n=78), improvements in Glasgow Coma Scale (GCS) score of more than three points, compared to preoperative measurement, were more frequently observed among the early (less than 3 hours between trauma onset and operation) decompressed cases (p=0.013). However, improvements of more than 4 or 5 points on the GCS were not affected by early decompression. Conclusion Early decompression of ASDH was not correlated with survival rate, but was related with neurological improvement (more than three points on the GCS). Accordingly, early decompression in ASDH, if indicated, may be of particular benefit. PMID:27182496

    Study Design Retrospective study. Purpose To evaluate the initial fixation using the cortical bone trajectory (CBT) technique for posterior lumbar fusion through assessment of the clear zones around the screws and the risk factors involved. Overview of Literature Postoperative radiolucent zones (clear zones) are an indicator of poor conventional pedicle screw fixation. Methods Between January 2013 and April 2014, 19 patients (8 men and 11 women) underwent posterior lumbar interbody fusion or posterior lumbar fusion using the CBT technique. A total of 109 screws were used for evaluation with measurement of the maximum insertional torque of last two screw rotations. Clear zone-positivity on plain radiographs was investigated 6 months after surgery. The relation between intraoperative insertional torque and clear zone-positivity was investigated by one-way analysis of variance. In addition, the correlation between clear zone-positivity and gender, age (<75 years old or >75 years old), or operative stabilization level (<2 or >3 vertebral levels) was evaluated using the chi-square test. Results Clear zones were observed around six screws (5.50%) in five patients (26.3%). The mean insertional torque (4.00±2.09 inlbs) of clear zone-positive screws was lower than that of clear zone-negative screws (8.12±0.50 in-lbs), but the difference was not significant. There was a significant correlation between clear zone-positivity and operative level of stabilization. Conclusions The low incidence of clear zone-positive screws indicates good initial fixation using the CBT technique. Multilevel fusions may be risk factors for clear zone generation. PMID:26713120

    OBJECTIVES: Newborns who undergo surgery for gastroschisis correction may present with oliguria, anasarca, prolonged postoperative ileus, and infection. New postoperative therapeutic procedures were tested with the objective of improving postoperative outcome. PATIENTS AND METHODS: One hundred thirty-six newborns participated in one of two phases. Newborns in the first phase received infusions of large volumes of crystalloid solution and integral enteral formula, and newborns in the second phase received crystalloid solutions in smaller volumes, with albumin solution infusion when necessary and the late introduction of a semi-elemental diet. The studied variables were serum sodium and albumin levels, the need for albumin solution expansion, the occurrence of anasarca, the length of time on parenteral nutrition, the length of time before initiating an enteral diet and reaching a full enteral diet, orotracheal intubation time, length of hospitalization, and survival rates. RESULTS: Serum sodium levels were higher in newborns in the second phase. There was a correlation between low serum sodium levels and orotracheal intubation time; additionally, low serum albumin levels correlated with the length of time before the initiation of an oral diet and the time until a full enteral diet was reached. However, the discharge weights of newborns in the second phase were higher than in the first phase. The other studied variables, including survival rates (83.4% and 92.0%, respectively), were similar for both phases. CONCLUSIONS: The administration of an albumin solution to newborns in the early postoperative period following gastroschisis repair increased their low serum sodium levels but did not improve the final outcome. The introduction of a semi-elemental diet promoted an increase in body weight at the time of discharge. PMID:22358234

    Background & Objective Placental abruption, an ischemic placental disorder, complicates about 1 in 100 pregnancies, and is an important cause of maternal and perinatal morbidity and mortality worldwide. Metabolomics holds promise for improving the phenotyping, prediction and understanding of pathophysiologic mechanisms of complex clinical disorders including abruption. We sought to evaluate maternal early pregnancy pre-diagnostic serum metabolic profiles and abnormal vaginal bleeding as predictors of abruption later in pregnancy. Methods Maternal serum was collected in early pregnancy (mean 16 weeks, range 15 to 22 weeks) from 51 abruption cases and 51 controls. Quantitative targeted metabolic profiles of serum were acquired using electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS/MS) and the Absolute IDQ® p180 kit. Maternal sociodemographic characteristics and reproductive history were abstracted from medical records. Stepwise logistic regression models were developed to evaluate the extent to which metabolites aid in the prediction of abruption. We evaluated the predictive performance of the set of selected metabolites using a receiver operating characteristics (ROC) curve analysis and area under the curve (AUC). Results Early pregnancy vaginal bleeding, dodecanoylcarnitine/dodecenoylcarnitine (C12 / C12:1), and phosphatidylcholine acyl-alkyl C 38:1 (PC ae C38:1) strongly predict abruption risk. The AUC for these metabolites alone was 0.68, for early pregnancy vaginal bleeding alone was 0.65, and combined the AUC improved to 0.75 with the addition of quantitative metabolite data (P = 0.003). Conclusion Metabolomic profiles of early pregnancy maternal serum samples in addition to the clinical symptom, vaginal bleeding, may serve as important markers for the prediction of abruption. Larger studies are necessary to corroborate and validate these findings in other cohorts. PMID:27300725

    Significant advances have been made in detecting cancer therapeutics-related cardiac dysfunction with serum biomarkers, cardiovascular MRI, echocardiography and multi-modality approaches. Serum biomarkers, notably cardiac troponins and natriuretic peptides, have been evaluated for their prognostic ability in predicting left ventricular dysfunction. Imaging modalities, such as cardiovascular MRI and echocardiography, have been used for cardiac surveillance of patients with cancer undergoing chemotherapy. Developments in imaging, specifically myocardial deformation imaging, also known as strain, have been shown to be sensitive tools in detecting early changes in cardiac function. This review aims to synthesize the evidence that supports emerging serum biomarkers and complementary imaging modalities that continue to enhance the detection of cancer therapeutics-related cardiac dysfunction.

    The purpose of this study was to evaluate the relationship between five previously established serum osteoarthritis biomarkers and the severity of cartilage lesions in the knee. Cartilage damage (classified according to the Outerbridge scoring system) and serum concentrations of cartilage oligomeric matrix protein (COMP), collagen type II C-telopeptide (CTX-II), matrix metalloproteinase-3 (MMP-3), collagen type III N-propeptide, (PIIINP), and hyaluronic acid (HA) were determined in 79 patients who underwent knee arthroscopy or total knee replacement. HA and COMP concentrations were significantly higher in the Outerbridge score 1 and 2 groups, respectively. These results suggest that serum COMP and HA concentrations can be used to predict early cartilage lesions in the knee.

Measurement of the serum BSAP, CTX, NTX, and TRACP 5b concentrations may be useful for the early detection of bone nonunion. The serum NTX concentrations changed significantly in rabbits with bone nonunion. Further studies are required in order to determine the feasibility of using serum NTX concentrations for the early diagnosis of bone nonunion. PMID:28105092

    Objective The insulin-pancreatic acinar axis may play a major role in pancreatic function. Amylase is an exocrine enzyme that is produced by pancreatic acinar cells, and low serum amylase levels may be associated with endocrine diseases, such as metabolic syndrome and diabetes. We hypothesized that low serum amylase levels may be associated with impaired islet β cell function in type 2 diabetes. Therefore, we investigated the relationship between the serum amylase levels and islet β cell function in patients with early type 2 diabetes. Methods The cross-sectional study recruited 2327 patients with a mean of 1.71±1.62 years since their diagnosis of type 2 diabetes, and all participants were treated with lifestyle intervention alone. Serum amylase levels, the 75-g oral glucose tolerance test (OGTT) and metabolic risk factors were examined in all participants. The insulin sensitivity index (Matsuda index, ISIMatsuda) and insulin secretion index (ratio of total area-under-the-insulin-curve to glucose-curve, AUCins/glu) were derived from the OGTT. Integrated islet β cell function was assessed by the Insulin Secretion-Sensitivity Index-2 (ISSI-2) (ISIMatsuda multiplied by AUCins/glu). Results Serum amylase levels in the normal range were significantly correlated with ISIMatsuda, AUCins/glu and ISSI-2 (r = 0.203, 0.246 and 0.413, respectively, p<0.001). The association of the serum amylase levels with ISSI-2 (adjusted r = 0.363, p<0.001) was closer than the association with ISIMatsuda (adjusted r = 0.191, p<0.001) and AUCins/glu (adjusted r = 0.174, p<0.001) after adjusting for the anthropometric indices, time since the diagnosis of diabetes, lipid profiles, uric acid levels, estimated glomerular filtration rate, HbA1c levels, smoking and drinking using the partial correlation test. After adjusting for these metabolic risk factors in the multivariate regression analysis with the amylase levels as the dependent variable, ISSI-2 was the major independent contributor to

    With the numerous significant advances in surgical methodology--e.g., microinstrumentation, the operating microscope, the surgical keratometer, and intraocular lenses--that have been developed over the past two decades, both surgeons and patients have become increasingly aware of the final optic result of any surgical intervention. This is especially so since the development of refractive surgery, where good uncorrected vision is frequently the final arbiter of success. We have progressed to the stage where the optic manipulation of the cornea, whether intentional or otherwise, can be understood in terms of a number of variables. These include the preparation and closure of the surgical wound, the choice of suture material, and both intraoperative and postoperative manipulations. Where these have failed and postoperative astigmatism still occurs, a number of surgical procedures are available to reduce the astigmatic error to an acceptable level.

    Background and Aims Primary hepatocellular carcinoma (HCC) is usually presented in inflamed fibrotic/cirrhotic liver with extensive lymphocyte infiltration. We examined the associations between the HCC early recurrence and alterations in serum levels of inflammatory cytokines. Methods A cohort of 105 HCC patients with chronic hepatitis B virus infection were included. Pre-therapy, we quantified their serum concentrations of Th1-, Th2-, Th17-, Treg-related, and other cytokines that have been reported to be associated with poor prognosis in human cancers. IL17-producing T-cells were generated in vitro from HCC patients and co-cultured with HCC cell lines separated by a 0.4 µM transwell. Results All the 105 cases of HCC patients had liver cirrhosis. The patients who suffered from HCC early recurrence had higher pre-therapy serum levels of IL17 and lower levels of IL10 than those who did not suffer from recurrence after curative hepatectomy. After adjustment for general tumor clinicopathological factors, elevated serum levels of IL17 (≥0.9 pg/ml) was found to be an independent risk factor for HCC early recurrence with a hazard ratio of 2.46 (95%CI 1.34–4.51). Patients with bigger tumors (>5 cm in diameter) and elevated serum levels of IL17 had the highest risk of early recurrence as compared to those with only one of these factors (P = 0.009) or without any (P<0.001). These factors showed similar effects on the HCC patient overall survival. Intrahepatic infiltrated T-cells in HCC patients were identified as the major IL17-producing cells. Proliferation of HCC cells, QGY-7703, was augmented QGY-7703, was augmented in the presence of IL17-producing T-cells. This effect diminished after neutralizing antibody against human IL17A or TNFα was included. Conclusion Both tumors and IL17 from liver infiltrated T-cells contributed to HCC early recurrence and progression after curative resection. Pre-therapy serum IL17 levels may serve as an additional indicator for

    Introduction: Fentanyl iontophoretic transdermal system (ITS) (IONSYS®, The Medicines Company, Parsippany, NJ, USA) and morphine intravenous (IV) patient-controlled analgesia (PCA) have demonstrated equivalent pain control in several published studies. The primary objective of the current study was to compare fentanyl ITS with morphine IV PCA with regard to the patient’s ability to mobilise with acute postoperative pain. Methods: In this multicentre, open-label, randomised, active-controlled, prospective phase IV study, postoperative patients initially received IV morphine and were titrated to pain score ⩽ 4out of 10 on a Numeric Rating Scale (NRS) and then received fentanyl ITS (up to 240 µg (6 doses)/hour; up to a maximum of 3.2 mg (80 doses)/24 hours) or morphine IV PCA (doses up to 20 mg morphine/2 hours, up to 240 mg/24 hours). The primary efficacy measure was ability to mobilise, assessed using patient responses to three validated questions regarding mobility on a 6-point Likert scale (0 = no difficulty to mobilise to 5 = a very great deal of difficulty to mobilise). The study was originally planned to include ~200 patients. However, following the early suspension and termination of the study, a total of 108 patients were randomised to study treatment. Results: One hundred and eight patients were recruited prior to undergoing surgical procedures (orthopaedic surgical procedures (72%) or underwent major abdominal procedures (28%)). Postoperatively, 58 were randomised to receive fentanyl ITS, and 50 to morphine IV PCA. Fentanyl ITS patients had a greater ability to mobilise at the time of stopping study drug, with an adjusted mean ability to mobilise score (95% confidence interval (CI)) of 0.14 (−0.19, 0.47) for fentanyl ITS patients and 2.37 (1.98, 2.76) for morphine IV PCA patients (p < 0.001). Conclusion: Patients treated with fentanyl ITS reported that they were better able to mobilise than patients treated with morphine IV PCA, at all time

    Purpose We aimed to see the frequency of concomitant ischemic heart disease (IHD) in Korean patients with abdominal aortic aneurysm (AAA) and to determine risk factors for an early postoperative acute myocardial infarction (PAMI) after elective open or endovascular AAA repair. Methods We retrospectively reviewed a database of patients who underwent elective AAA repair over the past 11 years. Patients were classified into 3 groups: control group; group I, medical IHD treatment; group II, invasive IHD treatment. Rates of PAMI and mortality at 30 days were compiled and compared between groups according to the type of AAA repair. Results Six hundred two elective repairs of infrarenal or juxtarenal AAAs were enrolled in this study. The patients were classified into control group (n = 398, 66.1%), group I (n = 73, 12.1%) and group II (n = 131, 21.8%). PAMI developed more frequently after open surgical repair (OSR) than after endovascular aneurysm repair (EVAR) (5.4% vs. 1.3%, P = 0.012). In OSR patients (n = 373), PAMI developed 2.1% in control group, 18.0% in group I and 7.1% in group II (P < 0.001). In EVAR group (n = 229), PAMI developed 0.6% in control group, 4.3% in group I and 2.2% in group II (P = 0.211). On the multivariable analysis of risk factors of PAMI, PAMI developed more frequently in patients with positive functional stress test. Conclusion The prevalence of concomitant IHD was 34% in Korean AAA patients. The risk of PAMI was significantly higher after OSR compared to EVAR and in patients with IHD compared to control group. Though we found some risk factors for PAMI, these were not applied to postoperative mortality rate. PMID:26942161

    Blood-based early detection of breast cancer has recently gained novel momentum, as liquid biopsy diagnostics is a fast emerging field. In this study, we aimed to identify secreted proteins which are up-regulated both in tumour tissue and serum samples of breast cancer patients compared to normal tissue and sera. Based on two independent tissue cohorts (n = 75 and n = 229) and one serum cohort (n = 80) of human breast cancer and healthy serum samples, we characterised AGR3 as a novel potential biomarker both for breast cancer prognosis and early breast cancer detection from blood. AGR3 expression in breast tumours is significantly associated with oestrogen receptor α (P<0.001) and lower tumour grade (P<0.01). Interestingly, AGR3 protein expression correlates with unfavourable outcome in low (G1) and intermediate (G2) grade breast tumours (multivariate hazard ratio: 2.186, 95% CI: 1.008-4.740, P<0.05) indicating an independent prognostic impact. In sera analysed by ELISA technique, AGR3 protein concentration was significantly (P<0.001) elevated in samples from breast cancer patients (n = 40, mainly low stage tumours) compared to healthy controls (n = 40). To develop a suitable biomarker panel for early breast cancer detection, we measured AGR2 protein in human serum samples in parallel. The combined AGR3/AGR2 biomarker panel achieved a sensitivity of 64.5% and a specificity of 89.5% as shown by receiver operating characteristic (ROC) curve statistics. Thus our data clearly show the potential usability of AGR3 and AGR2 as biomarkers for blood-based early detection of human breast cancer.

    Minimally invasive lumbar interbody fusion (MILIF) offers potential for reduced operative morbidity and earlier recovery compared with open procedures for patients with degenerative lumbar disorders (DLD). Firm conclusions about advantages of MILIF over open procedures cannot be made because of limited number of large studies of MILIF in a real-world setting. Clinical effectiveness of MILIF in a large, unselected real-world patient population was assessed in this Prospective, monitored, international, multicenter, observational study. Objective: To observe and document short-term recovery after minimally invasive interbody fusion for DLD. Materials and Methods: In a predefined 4-week analysis from this study, experienced surgeons (≥30 MILIF surgeries pre-study) treated patients with DLD by one- or two-level MILIF. The primary study objective was to document patients’ short-term post-interventional recovery (primary objective) including back/leg pain (visual analog scale [VAS]), disability (Oswestry Disability Index [ODI]), health status (EQ-5D) and Patient satisfaction. Results: At 4 weeks, 249 of 252 patients were remaining in the study; the majority received one-level MILIF (83%) and TLIF was the preferred approach (94.8%). For one-level (and two-level) procedures, surgery duration was 128 (182) min, fluoroscopy time 115 (154) sec, and blood-loss 164 (233) mL. Time to first ambulation was 1.3 days and time to study-defined surgery recovery was 3.2 days. Patients reported significantly (P < 0.0001) reduced back pain (VAS: 2.9 vs 6.2), leg pain (VAS: 2.5 vs 5.9), and disability (ODI: 34.5% vs 45.5%), and a significantly (P < 0.0001) improved health status (EQ-5D index: 0.61 vs 0.34; EQ VAS: 65.4 vs 52.9) 4 weeks postoperatively. One adverse event was classified as related to the minimally invasive surgical approach. No deep site infections or deaths were reported. Conclusions: For experienced surgeons, MILIF for DLD demonstrated early benefits (short time to

    Obesity and diabetes are increasing in epidemic proportions globally. Lipocalin-2 (LCN-2) is an inflammatory adipocytokine and obesity-related marker of low-grade inflammation. We aimed to investigate, for first time, the possible role of LCN-2 expression and serum levels in prediction of impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) among obese Egyptian women. This study included 188 obese women and 180 controls. Obese women were subdivided into three subgroups according to their fasting blood glucose, normal glucose tolerance (NGT), IGT and T2DM. Circulating LCN-2 expression levels were determined by real time polymerase chain reaction. Serum LCN-2 concentrations were assessed by ELISA. Our findings revealed that LCN-2 expression and serum levels were higher in obese women compared to lean controls. They were higher in IGT and T2DM obese cases than in NGT obese women. Receiver operating characteristic analyses revealed that LCN-2 expression level was a useful biomarker discriminating IGT from NGT and T2DM from IGT obese women (AUC were 0.735 and 0.740, respectively). It was an independent predictor of IGT and T2DM among obese women. Serum LCN-2 level was a useful biomarker discriminating IGT from NGT and T2DM from IGT obese women (AUC were 0.705 and 0.728, respectively). It was independent predictor of T2DM without predicting IGT among obese women. The power of combined LCN-2 serum levels and expression in discriminating between IGT from NGT and T2DM from IGT obese women was high (AUC = 0.717 and 0.741, respectively). In conclusion, LCN-2 expression and serum levels could discriminate IGT from NGT and T2DM from IGT obese women and early predicting T2DM among obese women. While, LCN-2 expression level was the independent predictor of IGT in obese women. Combination of both LCN-2 expression and serum levels improved their diagnostic value in early detection of IGT and T2DM among obese women. © 2017 IUBMB Life, 69(2):88-97, 2017.

    A set of proteins antigenically related to the c-fos protein (Fos) are induced by serum in fibroblasts. To isolate cDNA clones of genes encoding such proteins, a lambda gt11 expression cDNA library constructed from serum-stimulated rat fibroblasts was screened with antibodies raised against a hydrophilic region (amino acids 127 to 152) of Fos. One of the positive clones identified, termed fra-1 (Fos-related antigen) was characterized. It encoded a protein that shared several regions of extensive amino acid homology with Fos (including the region that showed similarity to both the yeast GCN4 regulatory protein and the protein encoded by the jun oncogene), although its nucleotide sequence was considerably diverged from that of the c-fos gene. Only a subset of the agents and conditions that activated c-fos also induced fra-1. Induction of fra-1 expression following serum stimulation was delayed compared with that of c-fos. However, like c-fos, fra-1 was induced rapidly by serum in the presence of protein synthesis inhibitors. Thus, a family of Fos-related, inducible genes are involved in the cellular immediate-early transcriptional response to extracellular stimuli. Images PMID:3133553

    Purpose Hepatocellular carcinoma (HCC) is a primary cancer of the liver that is predominantly the result of infection with a hepatotropic virus such as hepatitis B virus (HBV) or hepatitis C virus (HCV). As liver cancer is often asymptomatic, the development of sensitive non-invasive biomarkers is needed for early detection and improved survival. Experimental Design We have previously identified alterations in the N-linked glycosylation of serum proteins with the development of HCC and identified many of the proteins that contained the altered glycosylation. In the current study, we compared the ability of the identified proteins to diagnose HCC with the total serum glycan analysis. Results Surprisingly, glycan analysis of total serum had the greatest ability to distinguish HCC from cirrhosis with an AUROC of 0.851, a sensitivity of 73% at a specificity of 88%. When total glycan sequencing was combined with alpha-fetoprotein (AFP), the sensitivity increased to 95% at a specificity of 90%. Conclusion and clinical relevance Changes in glycosylation as detected in whole serum could be used to diagnose HCC with greater sensitivity and specificity than that observed through the analysis of specific protein glycoforms or protein levels. Such an assay could have value in the management of those at risk for the development of HCC. PMID:23857719

    The most common causes of acute pancreatitis (AP) are biliary tract diseases with cholestasis and alcohol consumption. In 10%–15% of patients, etiology determination is difficult. Identification of the etiology allows for the implementation of adequate treatment. The aim of this study was to assess the utility of the serum concentrations of total bile acids (TBA) to diagnose AP etiology in the early phase of the disease. We included 66 patients with AP, admitted within the first 24 h from the onset of symptoms. TBA were measured in serum at 24, 48, and 72 h from the onset of AP, using an automated fifth generation assay. The bilirubin-to-TBA ratio (B/TBA) was calculated. TBA was highest on the first day of AP and decreased subsequently. In patients with biliary etiology, serum TBA was significantly higher compared to those with alcoholic and other etiologies. B/TBA was significantly higher in patients with alcoholic etiology. At admission, the cut-off values of 4.7 µmol/L for TBA and 4.22 for the B/TBA ratio allowed for a differentiation between biliary and other etiologies of AP with a diagnostic accuracy of 85 and 83%. Both TBA and B/TBA may help in the diagnosis of AP etiology in the early phase of AP. PMID:28067818

    Effective triage of dengue patients early in the disease course for in- or out-patient management would be useful for optimal healthcare resource utilization while minimizing poor clinical outcome due to delayed intervention. Yet, early prognosis of severe dengue is hampered by the heterogeneity in clinical presentation and routine hematological and biochemical measurements in dengue patients that collectively correlates poorly with eventual clinical outcome. Herein, untargeted liquid-chromatography mass spectrometry metabolomics of serum from patients with dengue fever (DF) and dengue hemorrhagic fever (DHF) in the febrile phase (<96 h) was used to globally probe the serum metabolome to uncover early prognostic biomarkers of DHF. We identified 20 metabolites that are differentially enriched (p<0.05, fold change >1.5) in the serum, among which are two products of tryptophan metabolism-serotonin and kynurenine. Serotonin, involved in platelet aggregation and activation decreased significantly, whereas kynurenine, an immunomodulator, increased significantly in patients with DHF, consistent with thrombocytopenia and immunopathology in severe dengue. To sensitively and accurately evaluate serotonin levels as prognostic biomarkers, we implemented stable-isotope dilution mass spectrometry and used convalescence samples as their own controls. DHF serotonin was significantly 1.98 fold lower in febrile compared to convalescence phase, and significantly 1.76 fold lower compared to DF in the febrile phase of illness. Thus, serotonin alone provided good prognostic utility (Area Under Curve, AUC of serotonin = 0.8). Additionally, immune mediators associated with DHF may further increase the predictive ability than just serotonin alone. Nine cytokines, including IFN-γ, IL-1β, IL-4, IL-8, G-CSF, MIP-1β, FGF basic, TNFα and RANTES were significantly different between DF and DHF, among which IFN-γ ranked top by multivariate statistics. Combining serotonin and IFN-γ improved

    Purpose: A nomogram is a predictive statistical model that generates the continuous probability of a clinical event such as death or recurrence. The aim of the study was to construct a nomogram to predict 5-year overall survival after postoperative radiation therapy for stage IB to IIA cervical cancer. Methods and Materials: The clinical data from 1702 patients with early-stage cervical cancer, treated at 10 participating hospitals from 1990 to 2011, were reviewed to develop a prediction nomogram based on the Cox proportional hazards model. Demographic, clinical, and pathologic variables were included and analyzed to formulate the nomogram. The discrimination and calibration power of the model was measured using a concordance index (c-index) and calibration curve. Results: The median follow-up period for surviving patients was 75.6 months, and the 5-year overall survival probability was 87.1%. The final model was constructed using the following variables: age, number of positive pelvic lymph nodes, parametrial invasion, lymphovascular invasion, and the use of concurrent chemotherapy. The nomogram predicted the 5-year overall survival with a c-index of 0.69, which was superior to the predictive power of the International Federation of Gynecology and Obstetrics (FIGO) staging system (c-index of 0.54). Conclusions: A survival-predicting nomogram that offers an accurate level of prediction and discrimination was developed based on a large multi-center study. The model may be more useful than the FIGO staging system for counseling individual patients regarding prognosis.

    A variety of surgical approaches are available for the treatment of spine diseases. Complications can arise intraoperatively, in the immediate postoperative period, or in a delayed fashion. These complications may lead to severe or even permanent morbidity if left unrecognized and untreated [1-4]. Here we review a range of complications in the early postoperative period from more benign complications such as postoperative nausea and vomiting (PONV) to more feared complications leading to permanent loss of neurological function or death [5]. Perioperative pain management is covered in a separate review (Chapter 8).

    Knee osteoarthritis (OA) is a leading cause of physical disability. At the early stage of knee OA, the increase in synovial fluid cytokine concentrations could contribute to the pathogenesis of OA by degrading articular cartilage. It is unknown, however, if inflammatory cytokines increase systemically at the early or advanced stage of knee OA. The systemic increase of inflammatory cytokines could be detrimental to the endogenous status of micronutrients that protect against excessive inflammation and cytokine-mediated events. The purpose of this study was to test the hypothesis that an increase in serum cytokines associate with a decrease in circulating micronutrients in subjects with early compared to advanced knee OA. Advanced knee OA subjects (n=14) displayed radiographic, pain, and muscular weakness symptoms of knee OA. Early knee OA subjects (n=14) were matched (age, gender, and body mass index) to the advanced OA group and displayed one or two of the aforementioned symptoms of knee OA. Inflammatory cytokines, vitamins C (ascorbic acid), D (25-hydroxyvitamin D), and E (α- and γ-tocopherols), and β-carotene were measured in fasting blood samples. In the early OA group, serum tumor necrosis factor (TNF)-α, interleukin (IL)-5, IL-6, IL-12, and IL-13 concentrations were significantly (all p<0.05) increased. Circulating ascorbic acid, 25-hydroxyvitamin D, α- and γ-tocopherol's, and β-carotene concentrations were not significantly different between groups. Based on these preliminary results, we conclude that the systemic increase of inflammatory cytokines is not associated with a decrease in circulating micronutrients in subjects with early compared to advanced knee OA.

    In response to diverse environmental stimuli at different infection sites, Pseudomonas aeruginosa, a serious nosocomial pathogen, coordinates the production of different virulence factors through a complicated network of the hierarchical quorum-sensing (QS) systems including the las, rhl, and the 2-alkyl-4-quinolone-related QS systems. We recently showed that at early stages of growth serum alters the expression of numerous P. aeruginosa genes. In this study, we utilized transcriptional analysis and enzyme assays to examine the effect of serum on the QS and QS-controlled virulence factors during early and late phases of growth of the P. aeruginosa strain PAO1. At early phase, serum repressed the transcription of lasI, rhlI, and pqsA but not lasR or rhlR. However, at late phase, serum enhanced the expression of all QS genes. Serum produced a similar effect on the synthesis of the autoinducers 3OC12-HSL, C4-HSL, and HHQ/PQS. Additionally, serum repressed the expression of several QS-controlled genes in the early phase, but enhanced them in the late phase. Furthermore, serum influenced the expression of different QS-positive (vqsR, gacA, and vfr) as well as QS-negative (rpoN, qscR, mvaT, and rsmA) regulatory genes at either early or late phases of growth. However, with the exception of PAOΔvfr, we detected comparable levels of lasI/lasR expression in PAO1 and PAO1 mutants defective in these regulatory genes. At late stationary phase, serum failed to enhance lasI/lasR expression in PAOΔvfr. These results suggest that depending on the phase of growth, serum differentially influenced the expression of P. aeruginosa QS and QS-controlled virulence genes. In late phase, serum enhanced the expression of las genes through vfr. PMID:24436158

    Objective: The aim of this study was to compare the efficacy of oral, intra muscular and transdermal diclofenac sodium for pain treatment in patients undergoing laparoscopic cholecystectomy, and their effect on postoperative opioid consumption. Methods: Following informed consent, 90 ASA I-II patients scheduled for laparoscopic cholecystectomy were randomized into three groups. Group PO got oral diclofenac sodium 1 hour before the operation, Group IM 75 mg diclofenac sodium intra muscular and Group TD diclofenac sodium patch 6 hours before the operation. Patients were not premedicated. Routine anaesthesia induction was used. After the operation in post anaesthesia care unit tramadol HCl infusion was delivered by intravenous patient controlled analgesia (iv PCA). Ramsey Sedation Score (RSS), Modified Aldrete’s Score System(MASS) and Visual Analog Scale Pain Score (VAS) was used for postoperative evaluation. Postoperative opioid consumption was recorded. Results: Demographic characteristics, intraoperative and postoperative hemodynamics of the patients were similar between groups. Postoperative VAS were lower at all time points in Group IM and Group TD than in Group PO. Lowest Postoperative RSS were in Group IM and the highest were in Group PO, and the difference between groups was significant. There was no significant difference in Postoperative MASS between groups. Postoperative tramadol consumption was statistically different between groups. Tramadol consumption in Group IM and Group TD was lower than Group PO. Postoperative nausea and vomiting was not observed. Local complications related to transdermal and intra muscular applications was not reported. Conclusion: In patients undergoing ambulatory laparoscopic cholecystectomy, a noninvasive application transdermal diclofenac sodium is as effective as intramuscular diclofenac sodium and can be preferred in postoperative pain treatment.

    Novel blood-based screening tests are strongly desirable for early detection of colorectal cancer (CRC). We aimed to identify and evaluate autoantibodies against tumor-associated antigens as biomarkers for early detection of CRC. 380 clinically identified CRC patients and samples of participants with selected findings from a cohort of screening colonoscopy participants in 2005–2013 (N=6826) were included in this analysis. Sixty-four serum autoantibody markers were measured by multiplex bead-based serological assays. A two-step approach with selection of biomarkers in a training set, and validation of findings in a validation set, the latter exclusively including participants from the screening setting, was applied. Anti-MAGEA4 exhibited the highest sensitivity for detecting early stage CRC and advanced adenoma. Multi-marker combinations substantially increased sensitivity at the price of a moderate loss of specificity. Anti-TP53, anti-IMPDH2, anti-MDM2 and anti-MAGEA4 were consistently included in the best-performing 4-, 5-, and 6-marker combinations. This four-marker panel yielded a sensitivity of 26% (95% CI, 13–45%) for early stage CRC at a specificity of 90% (95% CI, 83–94%) in the validation set. Notably, it also detected 20% (95% CI, 13–29%) of advanced adenomas. Taken together, the identified biomarkers could contribute to the development of a useful multi-marker blood-based test for CRC early detection. PMID:26909861

    Hyperkalemia occurs frequently in hospitalized patients and is of particular concern for those who have undergone surgery, with postoperative care provided by clinicians of many disciplines. This review describes the normal physiology and how multiple perioperative factors can disrupt potassium homeostasis and lead to severe elevations in plasma potassium concentration. The pathophysiologic basis of diverse causes of hyperkalemia was used to broadly classify etiologies into those with altered potassium distribution (e.g. increased potassium release from cells or other transcellular shifts), reduced urinary excretion (e.g. reduced sodium delivery, volume depletion, and hypoaldosteronism), or an exogenous potassium load (e.g. blood transfusions). Surgical conditions of particular concern involve: rhabdomyolysis from malpositioning, trauma or medications; bariatric surgery; vascular procedures with tissue ischemia; acidosis; hypovolemia; and volume or blood product resuscitation. Certain acute conditions and chronic co-morbidities present particular risk. These include chronic kidney disease, diabetes mellitus, many outpatient preoperative medications (e.g. beta blockers, salt substitutes), and inpatient agents (e.g. succinylcholine, hyperosmolar volume expanders). Clinicians need to be aware of these pathophysiologic mechanisms for developing perioperative hyperkalemia as many of the risks can be minimized or avoided.

    Objective The goals of this study were to describe the clinical and anatomic features of infants undergoing Kasai portoenterostomy (KPE) for biliary atresia (BA), and to examine associations between these parameters and outcomes. Methods Infants enrolled in the prospective Childhood Liver Disease Research and Education Network, who underwent KPE were studied. Patients enrolled in a blinded, interventional trial were excluded from survival analysis. Primary end-points were successful surgical drainage (total bilirubin less than 2 mg/dL within the first three months), transplant-free survival (Kaplan-Meier), and time to transplant/death (Cox regression). Results KPE was performed in 244 infants (54% female; mean age 65± 29 days). Transplant-free survival was 53.7% and 46.7% at 1 and 2 years post-KPE. The risk of transplant/death was significantly lower in the 45.6% of patients who achieved successful bile drainage within 3 months post-KPE (HR 0.08, p<0.001). The risk of transplant/death was increased in patients with porta hepatis atresia (Ohi Type II and III vs. Type I; HR 2.03, p=0.030), non-patent common bile duct (Ohi Subtype b, c, and d vs. a; HR 4.31, p=0.022), BA splenic malformation syndrome (HR 1.92, p=0.025), ascites > 20 ml (HR=1.90, p=0.0230), nodular liver appearance compared to firm (HR=1.61, p=0.008), and age at KPE ≥ 75 days (HR 1.73, p<0.002). Outcome was not associated with gestational age, gender, race, ethnicity, or extent of porta hepatis dissection. Conclusion Anatomic pattern of BA, BASM, presence of ascites and nodular liver appearance at KPE, and early postoperative jaundice clearance are significant predictors of transplant-free survival.

    Cucurbitacins are a group of tetracyclic triterpenoids, known for centuries for their anti-cancer and anti-inflammatory properties, which are being actively investigated over the past decades in order to elucidate their mechanism of action. In perspective of being used as therapeutic molecules, a pharmacokinetic characterization is crucial to assess the affinity toward blood carrier proteins and extrapolate distribution volumes. Usually, pharmacokinetic data are first collected on animal models and later translated to humans; therefore, an early characterization of the interaction with carrier proteins from different species is highly desirable. In the present study, the interactions of cucurbitacins E and I with human and rat serum albumins (HSA and RSA) were investigated by means of surface plasmon resonance (SPR)-based optical biosensing and circular dichroism (CD) spectroscopy. Active HSA and RSA sensor chip surfaces were prepared through an amine coupling reaction protocol, and the equilibrium dissociation constants (Kd) for the different cucurbitacins-serum albumins complexes were then determined by SPR analysis. Further information on the binding of cucurbitacins to serum albumins was obtained by CD competition experiments with biliverdin, a specific marker binding to subdomain IB of HSA. SPR data unveiled a previously unreported binding event between CucI and HSA; the determined binding affinities of both compounds were slightly higher for RSA with respect to HSA, even though all the compounds can be ranked as high-affinity binders for both carriers. CD analysis showed that the two cucurbitacins modify the binding of biliverdin to serum albumins through opposite allosteric modulation (positive for HSA, negative for RSA), confirming the need for caution in the translation of pharmacokinetic data across species.

    N-3 polyunsaturated fatty acids (PUFAs), especially long-chain types such as docosahexaenoic acid, are important nutrients in pregnancy, but the relationship between n-3 PUFA levels and perinatal and postnatal depression remains controversial. This study examined the possible relationship between serum n-3 PUFA levels and psychological distress among expectant mothers in early pregnancy. Data and specimen samples were obtained in a birth cohort study started at Toyama Regional Center in July 2012 as an adjunct study of the Japan Environment and Children's Study. Blood samples were collected at 9-14 weeks' gestation (75% of samples) or after 15 weeks (25%). Subjects with a Kessler Psychological Distress Scale score (K6) ⩾ 9 were assigned to the psychological distress group (n=283). The control group (n=283) was matched for age, educational level and family income. Fatty acid composition was determined from serum samples by gas chromatography. Associations between fatty acid levels and incident psychological distress were evaluated by logistic regression. After adjusting for possible confounders, eicosapentaenoic acid showed an inverse association with risk of psychological distress, with an odds ratio of 0.47 (95% confidence interval: 0.30, 0.73) for the highest tertile. This inverse association remained even after applying a higher cutoff score (K6 ⩾ 13) indicating severe psychological distress (74 pairs). We believe this is the first study to reveal the associations between serum n-3 PUFAs and risk of psychological distress in early pregnancy. Further research is required to verify the causality of these associations.

    Two experiments were conducted to evaluate the effects of dietary supplementation with Astragalus polysaccharide (APS) on growth performance, apparent ileal digestibilities (AID) of amino acids (AA), and their serum concentrations in early weaned piglets. In Exp. 1, 60 pigs were weaned at 21 days of age (BW 7.35 +/- 0.23 kg) and allocated to three treatments (20 pigs/treatment), representing supplementing 0.0% (control), 0.02% colistin (antibiotic), or 0.1% APS to a corn- and soybean meal-based diet. Average daily gain (ADG), average daily feed intake (ADFI), and feed/gain ratio (F/G) were measured weekly. Blood samples were obtained from five pigs selected randomly from each treatment for the measurement of serum free AA concentrations on days 7, 14, and 28. In Exp. 2, 12 pigs were weaned at 21 day of age (BW 7.64 +/- 0.71 kg), assigned to three treatment groups as in Exp. 1, and surgically fitted with a simple T-cannula at the terminal ileum. Ileal digesta samples were obtained for the measurement of AID of AA on days 7, 14 and 28. Dietary APS did not affect ADFI, but enhanced (P < 0.05) ADG by 11 and 4.4%, and improved F/G by 5.6 and 8.4%, respectively, compared with the control and antibiotic groups. Addition of APS to the diet increased AID and serum concentrations of most nutritionally essential and non-essential AA (including arginine, proline, glutamate, lysine, methionine, tryptophan, and threonine) on days 14 and 28. Circulating levels of total AA were affected by the age of pigs and treatment x time interaction. Collectively, these findings indicate that APS may ameliorate the digestive and absorptive function and regulate AA metabolism to beneficially increase the entry of dietary AA into the systemic circulation, which provide a mechanism to explain the growth-promoting effect of APS in early weaned piglets.

    It is well documented that bilateral hippocampal lesions or unilateral hippocampal lesion at birth causes impairment of contralateral LTP and long-term memory. However, effects of unilateral hippocampal lesion in adults on contralateral in vivo LTP and memory are not clear. We here examined the influence of unilateral electrolytic dorsal hippocampal lesion in adult rats on contralateral LTP in vivo and spatial memory during different postoperative phases. We found that acute unilateral hippocampal lesion had no effect on contralateral LTP. However, contralateral LTP was impaired at 1 week after lesion, and was restored to the control level at postoperative week 4. Similarly, spatial memory was also impaired at postoperative week 1, and was restored at postoperative week 4. In addition, the rats at postoperative week 1 showed stronger spatial exploratory behavior in a novel open-field environment. The sham operation had no effects on contralateral LTP, spatial memory and exploration at either postoperative week 1 or week 4. These results suggest that unilateral dorsal hippocampal lesion in adult rats causes transient contralateral LTP impairment and spatial memory deficit.

    Studies recently showed that intratracheal (IT) instillation of Libby amphibole (LA) increases circulating acute-phase proteins (APP; α-2 macroglobulin, A2M; and α-1 acid glycoprotein, AGP) and inflammatory biomarkers (osteopontin and lipocalin) in rats. In this study, objectives were to (1) compare changes in biomarkers of rats after instillation of different naturally occurring asbestos (NOA) minerals including LA, Sumas Mountain chrysotile (SM), El Dorado Hills tremolite (ED), and Ontario ferroactinolite cleavage fragments (ON), and (2) examine biomarkers after subchronic LA or amosite inhalation exposure. Rat-respirable fractions (aerodynamic diameter approximately 2.5 μm) prepared by water elutriation were delivered via a single IT instillation at doses of 0, 0.5, and 1.5 mg/rat in male F344 rats. Nose-only inhalation exposures were performed at 0, 1, 3.3, and 10 mg/m(3) for LA and at 3.3 mg /m(3) for amosite, 6h/d, 5 d/wk for 13 wk. Inflammation, metabolic syndrome, and cancer biomarkers were analyzed in the serum for up to 18 mo. IT instillation of some asbestos materials significantly increased serum AGP and A2M but to a varying degree (SM = LA > ON = ED). Numerical increases in interleukin (IL)-6 and osteopontin occurred in rats instilled with SM. SM and ED also elevated leptin and insulin at 15 mo, suggesting potential metabolic effects. LA inhalation tended to raise A2M at d 1 but not cytokines. Serum mesothelin appeared to elevate after 18 mo of LA inhalation. These results suggest that the lung injury induced by high levels of asbestos materials may be associated with systemic inflammatory changes and predisposition to insulin resistance.

    It is known that anterior cruciate ligament (ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, “ossified” knowledge or modalities really prove themselves in the literature? Could questions such as “is postoperative brace use really necessary?”, “what are the benefits of early restoration of the range of motion (ROM)?”, “to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?”, “how early can proprioception training and open chain exercises begin?”, “should strengthening training start in the immediate postoperative period?” be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper. PMID:25232521

    Aim. To investigate whether there is a correlation between early dental implant failure and low serum levels of vitamin D. Methods. All patients treated with dental implants in a single centre, in the period 2003–2015, were considered for enrollment in this study. The main outcome was early implant failure. The influence of patient-related variables on implant survival was calculated using the Chi-square test. Results. 822 patients treated with 1625 implants were selected for this study; 27 early failures (3.2%) were recorded. There was no link between gender, age, smoking, history of periodontitis, and an increased incidence of early failures. Statistical analysis reported 9 early failures (2.2%) in patients with serum levels of vitamin D > 30 ng/mL, 16 early failures (3.9%) in patients with levels between 10 and 30 ng/mL, and 2 early failures (9.0%) in patients with levels <10 ng/mL. Although there was an increasing trend in the incidence of early implant failures with the worsening of vitamin D deficiency, the difference between these 3 groups was not statistically significant (P = 0.15). Conclusions. This study failed in proving an effective link between low serum levels of vitamin D and an increased risk of early implant failure. Further studies are needed to investigate this topic.

    Lung cancer has the highest mortality rate among cancer patients in the world, in particular because most patients are only diagnosed at an advanced and noncurable stage. Computed tomography (CT) screening on high-risk individuals has shown that early detection could reduce the mortality rate. However, the still high false-positive rate of CT screening may harm healthy individuals because of unnecessary follow-up scans and invasive follow-up procedures. Alternatively, false-negative and indeterminate results may harm patients due to the delayed diagnosis and treatment of lung cancer. Noninvasive biomarkers, complementary to CT screening, could lower the false-positive and false-negative rate of CT screening at baseline and thereby reduce the number of patients that need follow-up and diagnose patients at an earlier stage of lung cancer. Lung cancer tissue generates lung cancer-associated proteins to which the immune system might produce high-affinity autoantibodies. This autoantibody response to tumor-associated antigens starts during early stage lung cancer and may endure over years. Identification of tumor-associated antigens or the corresponding autoantibodies in body fluids as potential noninvasive biomarkers could thus be an effective approach for early detection and monitoring of lung cancer. We provide an overview of differentially expressed protein, antigen, and autoantibody biomarkers that combined with CT imaging might be of clinical use for early detection of lung cancer.

    Abstract Unique change of circulating microRNAs (miRNAs) was recognized to occur in early oncogenesis, which conferred it the potential as biomarkers for early detection of cancer. However, its diagnostic capability for hepatocellular carcinoma (HCC) has not been fully understood. In this study, microarray analysis was applied to screen the initial candidate miRNA from both the supernatants of anoikis-resistant cellular models and the sera samples of HCC patients. The selected differentially expressed miRNAs were further verified in 115 HCC patients and 40 health controls by qRT-PCR. Among these, 4 miRNAs (miR-16-2-3p, 92a-3p, 107, and 3126-5p) were significantly changed in HCC patients compared with controls. Logistic regression analysis identified a 3-miRNA panel (miR-92-3p, miR-107, and miR-3126-5p) as valuable diagnostic marker for HCC, especially for early stage patients (AUC = 0.975) and for low-level AFP HCC patients (AUC = 0.971). In addition, the combination of 3-miRNA panel and AFP was even more effective for discriminating the early stage HCC patients (AUC = 0.988) and low-level AFP HCC patients (AUC = 0.989) from control. In conclusion, diagnostic efficacy of the combination of 3-miRNA panel and AFP was powerful for HCC diagnosis, especially in early tumor screening and low-level AFP patients. PMID:28079796

    Emerging evidence suggests that minor changes in serum creatinine concentrations are associated with increased hospital mortality rates. However, whether serum creatinine concentration (SCr) on admission and its change are associated with an increased mortality rate in mechanically ventilated patients is not known. We have conducted an international, prospective, observational cohort study enrolling adult intensive care unit patients under mechanical ventilation (MV). Recursive partitioning was used to determine the values of SCr at the start of MV (SCr0) and the change in SCr ([DeltaSCr] defined as the maximal difference between the value at start of MV [day 0] and the value on MV day 2 at 8:00 am) that best discriminate mortality. In-hospital mortality, adjusted by a proportional hazards model, was the primary outcome variable. A total of 2,807 patients were included; median age was 59 years and median Simplified Acute Physiology Score II was 44. All-cause in-hospital mortality was 44%. The variable that best discriminated outcome was a SCr0 greater than 1.40 mg/dL (mortality, 57% vs. 36% for patients with SCr0

    AIM: To investigate the diagnostic significance of Interleukin 12 (IL-12) in breast cancer (BC) and its correlation with other tumor markers including cancer antigen 15-3 (CA 15-3), carcinoembryonic antigen (CEA), matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinases-1 (TIMP-1), and MMP9/TIMP1 ratio. METHODS: Serum levels of IL-12, tumor markers, and hormone receptors were measured in 92 BC and 56 benign lesion patients versus 40 healthy subjects. Clinical stage, tumor size, lymph node metastasis, grade, and histological type were recorded. RESULTS: BC patients have lower IL-12, but higher CA 15.3 and CEA than control group. High levels of serum IL-12 were associated with lymph node positivity and progesterone receptor negativity. IL-12 was significant lower in invasive ductal carcinoma (IDC) compared to non IDC histological type. IL-12 was higher in patients with higher stage and grade but the difference was not statistically significant. IL-12 correlates negatively with MMP9/TIMP1 ratio. CONCLUSION: IL-12 is less specific than CEA for screening early BC, but its correlation with tumor aggressiveness and progression markers may have a prognostic value. PMID:27275301

    Cancer.gov

    Using the guidelines for cancer biomarker validation suggested by Pepe et al. (23), we propose to perform a Phase 2 study of DCP for the detection of early stage HCC. In this proposal, we plan to perform a larger case-control study to compare the sensitivity and specificity of DCP and AFP alone and in combination in differentiating patients with all stages of HCC and more importantly those with early HCC from patients with cirrhosis. We plan to enroll consecutive patients with HCC seen at 7 centers in the United States.

    Hodgkin's lymphoma is associated with immune dysregulation. Immune impairment often results in aberrant immune responses and lytic reactivation of ubiquitous Herpesviruses such as Epstein-Barr virus (EBV) in mucosal tissues. Accordingly, the specificity of IgA to EBV early-lytic antigens, which are important for reactivation, was evaluated to determine Hodgkin's lymphoma-specific sero-reactive patterns. Sera from 42 previously described patients with Hodgkin's lymphoma were compared to sera from 17 patients with infectious mononucleosis (IM), another EBV-related condition that often presents in a similar manner; and to sera from 15 healthy EBV-seropositive subjects. Flow cytometry analysis demonstrated that like IM sera, most Hodgkin's lymphoma sera contained IgA that labeled cells expressing EBV early-lytic antigens whereas healthy EBV-seropositive sera did not. Further evaluation to distinguish Hodgkin's lymphoma from IM showed that IgA in most Hodgkin's lymphoma, irrespective of the presence of EBV in primary tumors, detected only modified forms of EBV lytic Early Antigen-Diffuse (EA-D) while IM sera detected the un-modified form as well, further supporting the presence of immune dysregulation in Hodgkin's lymphoma patients. This IgA pattern distinguished Hodgkin's lymphoma from IM sera with a sensitivity of 92.9%, specificity 100%, positive predictive value 100%, and negative predictive value 85%. Our findings lay the groundwork for additional scientific and clinical investigation, particularly into the potential for developing Hodgkin's lymphoma -associated diagnostic and prognostic biomarkers.

    Circulating trimethylamine N-Oxide (TMAO) levels predict cardiovascular disease (CVD), possibly by impacting on cholesterol metabolism and oxidative stress. Because hepatic TMAO production is regulated by insulin signalling and it is unclear whether and to what extent circulating TMAO levels associate with CVD risk, independently of insulin resistance and its important determinants fatty liver and visceral obesity, we have now addressed this question in 220 subjects who participated in the Tübingen Lifestyle Intervention Program. Visceral fat mass (r = 0.40, p < 0.0001), liver fat content (r = 0.23, p = 0.0005) and TMAO levels (r = 0.26, p < 0.0001) associated positively, and insulin sensitivity associated negatively (r = −0.18, p = 0.009) with carotid intima-media thickness (cIMT). Higher TMAO levels (std.−Beta 0.11, p = 0.03) predicted increased cIMT, independently of age, sex and visceral fat mass. While during the lifestyle intervention most cardiovascular risk parameters improved, mean TMAO levels did not change (p = 0.18). However, cIMT decreased significantly (p = 0.0056) only in subjects in the tertile with the largest decrease of TMAO levels (>20%). We provide novel information that increased serum TMAO levels associate with increased cIMT, independently of established cardiovascular risk markers, including insulin resistance, visceral obesity and fatty liver. Furthermore, the decrease of cIMT during a lifestyle intervention may be related to the decrease of TMAO levels. PMID:27228955

    Adiponectin is the most abundant adipose-released protein that circulates in human plasma at high concentrations. The neuropeptides orexin A (OXA, hypocretin-1) and orexin B (OXB, hypocretin-2) are derived from a common precursor peptide, prepro-orexin and are produced mainly by neurons located in the lateral hypothalamus. It has been demonstrated that the peptides such as adiponectin and orexins have an important role in the regulation of energy metabolism and neuroendocrine functions. These hormones appear to be implicated in both normal and disturbed pregnancy. The objectives of this study were to determine adiponectin and orexin concentrations in the plasma and uterine luminal fluid (ULF) of pigs during early gestation and to explore the relationships between hormone concentrations and stages of pregnancy. The greatest plasma concentrations of adiponectin were observed on days 15-16 and 27-28 of pregnancy, and the least concentrations were on days 30-32 of gestation and on days 10-11 of the oestrous cycle. In ULF, adiponectin concentrations were greater on days 15-16 of pregnancy and on days 10-11 of the oestrous cycle than on days 10-11 and days 12-13 of pregnancy. The greatest OXA concentrations in the blood plasma were noted on days 10-16 of gestation, and the least OXA concentrations were on days 27-32 of pregnancy and on days 10-11 of the oestrous cycle. Orexin A concentrations in ULF were greater on days 10-11 of the cycle than throughout pregnancy. Serum OXB concentrations were greatest on days 10-11 and 30-32 of pregnancy, and least on days 12-28 of gestation. The greatest OXB concentrations in ULF were on days 10-13 of gestation, and the least OXB concentrations were on days 15-16 of pregnancy. This is first study to demonstrate the presence of adiponectin and orexins in the serum and ULF during early pregnancy of pigs as well as the relationships between adiponectin and orexin concentrations and the stage of pregnancy.

  19. Assessment of biochemical markers in the early post-burn period for predicting acute kidney injury and mortality in patients with major burn injury: comparison of serum creatinine, serum cystatin-C, plasma and urine neutrophil gelatinase-associated lipocalin

    PubMed Central

    2014-01-01

    Introduction The reported mortality rates range from 28% to 100% in burn patients who develop acute kidney injury (AKI) and from 50% to 100% among such patients treated with renal replacement therapy. Recently, the serum cystatin C and plasma and urine neutrophil gelatinase-associated lipocalin (NGAL) levels have been introduced as early biomarkers for AKI; the levels of these biomarkers are known to increase 24 to 48 hours before the serum creatinine levels increase. In this study, we aimed to estimate the diagnostic utility of the cystatin C and plasma and urine NGAL levels in the early post-burn period as biomarkers for predicting AKI and mortality in patients with major burn injuries. Methods From May 2011 to July 2012, 90 consecutive patients with a burn wound area comprising ≥ 20% of the total body surface area (TBSA) were enrolled in this study. Whole blood and urine samples were obtained for measuring the serum creatinine, serum cystatin C, and urine and plasma NGAL levels at 0, 3, 6, 12, 24, and 48 hours after admission. Receiver operating characteristic curve, area under the curve, and multivariate logistic regression analyses were performed to assess the predictive values of these biomarkers for AKI and mortality. Results In the multivariate logistic regression analysis, all variables, including age, percentage TBSA burned, sex, inhalation injury, and serum creatinine levels, serum cystatin C levels, and plasma and urine NGAL levels were independently associated with AKI development. Moreover, age, sex, percentage TBSA burned, and plasma and urine NGAL levels were independently associated with mortality. However, inhalation injury and the serum creatinine and cystatin C levels were not independently associated with mortality. Conclusions Massively burned patients who maintained high plasma and urine NGAL levels until 12 hours after admission were at the risk of developing early AKI and early mortality with burn shock. However, the plasma and urine

    Cognitive deficits are common in Parkinson's disease (PD) and many patients eventually develop dementia; however, its occurrence is unpredictable. Serum uric acid (UA) has been proposed as a biomarker of PD, both in the preclinical and clinical phase of the disease. The aim of this pilot study was to evaluate relationships between baseline serum UA levels and occurrence of mild cognitive impairment (MCI) at 4-year follow-up in a cohort of early PD patients. Early PD patients, not presenting concomitant diseases, cognitive impairment or treatment possibly interfering with UA levels, underwent neuropsychological testing at baseline and 4-year follow-up. UA levels were determined in serum at baseline. MCI was found in 23 out of 42 PD patients completing 4-year follow-up. Patients presenting MCI had significantly higher age at onset and lower Frontal Assessment Battery scores at baseline as compared with patients cognitively intact. Logistic regression analysis showed that both serum UA levels (OR = 0.54, p = 0.044) and age (OR = 1.16, p = 0.009) contribute to the occurrence of MCI at 4-year follow-up. Our pilot study suggests that lower levels of serum UA in the early disease stages are associated to the later occurrence of MCI. These results need to be confirmed by further studies on larger samples.

    The paper describes the carbohydrate, lipidic and nitrogen metabolism of the postoperative period which is subdivided into an early and a late phase. Since the metabolism of caloric substrates in the early postoperative period is a stress metabolism with glucose intolerance and wide protein catabolism, the authors emphasise that an insufficient caloric intake is worse than the fasting state and suggest that alternative caloric sources, such as branched chain amino acids, fatty acids and, even, ketonic bodies, should be used.

    The knee range of motion is an important outcome of total knee arthroplasty (TKA). According to previous studies, the knee range of motion temporarily decreases for approximately 1 month after TKA due to postoperative pain and quadriceps dysfunction following surgical invasion into the knee extensor mechanism. We describe our experience with a knee-extension training program based on a single-joint hybrid assistive limb (HAL-SJ, Cyberdyne Inc., Tsukuba, Japan) during the acute recovery phase after TKA. HAL-SJ is a wearable robot suit that facilitates the voluntary control of knee joint motion. A 76-year-old man underwent HAL-SJ-based knee-extension training, which enabled him to perform knee function training during the acute phase after TKA without causing increased pain. Thus, he regained the ability to fully extend his knee postoperatively. HAL-SJ-based knee-extension training can be used as a novel post-TKA rehabilitation modality. PMID:27774330

    There is no agreed technique for minimizing PONV (Postoperative Nausea and Vomiting) although some techniques are associated with low rate. Best practice involves identifying high risk patients and surgeries and use of prophylactic antiemetic where appropriate. Laparoscopic gynaecological surgery has high incidence of PONV (54-92%). An audit on the practice of antiemetic use in diagnostic laparoscopic gynaecological surgery was done in the department of anaesthesia of Aga Khan University Hospital from 1st January to 30th June 2006. We included all the patients scheduled for this procedure lasting less than 90 minutes. Anaesthetist involved in the audit identified the patient falling into the predetermined risk factors. The following facts about antiemetic were noted; whether the patients received any antiemetics or not, if it was prophylactic or rescue, type, dose route and timing of antiemetic. Patients were rated for any signs of nausea and vomiting (retching) after extubation in the operating room by the anaesthetist and in the recovery room or surgical day care unit (SDC) by the nurse who was briefed about it and was cross checked by the anaesthetist involved in the audit. This was done for two hours postoperatively. Our results showed that only 75% of patients with risk factors received an antiemetic. The most commonly used antiemetic was Metoclopramide. Eight percent of the patients had vomiting and all of them had received a prophylactic antiemetic. They received the same rescue antiemetic. This audit recommended institutional guidelines for the management of PONV. These should be based on evidence obtained from the published peer-reviewed studies. These guidelines could be communicated to health care workers involved in postoperative management of patients to help them achieve an optimal management strategy for this uncomfortable postoperative complication.

    Introduction This study was conducted according to GCP criteria as a prospective randomized cross-over study. The primary goal of the study was to determine clinical findings and patient satisfaction with postoperative treatment. 29 patients with a distal radius fracture that was surgically stabilized from volar and who met the inclusion criteria were enrolled over a 12-month period. Each patient randomly received either a dorsal plaster splint or a vacuum-fit flexible but blocked orthosis applied postoperatively in the operating theatre to achieve postoperative immobilization. After one week all patients were crossed over to the complementary device maintaining the immobilization until end of week 2. After week 2 both groups were allowed to exercise wrist mobility with a physiotherapist, in the orthosis group the device was deblocked, thus allowing limited wrist mobility. After week 4 the devices were removed in both groups. Follow-up exams were performed after postoperative weeks 1, 2, 4 and 12. Results and Discussion Results were determined after week 1 and 2 using SF 36 and a personally compiled questionnaire; after weeks 4 and 12 with a clinical check-up, calculation of ROM and the DASH Score. Comparison of the two groups showed a significant difference in ROM for volar flexion after 4 weeks, but no significant differences in DASH Score, duration of disability or x-ray findings. With regard to satisfaction with comfort and hygiene, patients were significantly more satisfied with the dynamic orthosis, and 23 of the 29 patients would prefer the flexible vacuum orthosis in future.

    Two types of prognostic signatures for predicting recurrent risk of ER+ breast cancer patients have been developed: one type for patients accepting surgery only and another type for patients receiving post-operative tamoxifen therapy. However, the first type of signature cannot distinguish high-risk patients who cannot benefit from tamoxifen therapy, while the second type of signature cannot identify patients who will be at low risk of recurrence even if they accept surgery only. In this study, we proposed to develop two coupled signatures to solve these problems based on within-sample relative expression orderings (REOs) of gene pairs. Firstly, we identified a prognostic signature of post-operative recurrent risk using 544 samples of ER+ breast cancer patients accepting surgery only. Then, applying this drug-free signature to 840 samples of patients receiving post-operative tamoxifen therapy, we recognized 553 samples of patients who would have been at high risk of recurrence if they had accepted surgery only and used these samples to develop a tamoxifen therapy benefit predictive signature. The two coupled signatures were validated in independent data. The signatures developed in this study are robust against experimental batch effects and applicable at the individual levels, which can facilitate the clinical decision of tamoxifen therapy.

    There is little information on the early kinetics of hepatitis delta virus (HDV) and hepatitis B surface antigen (HBsAg) during interferon-α therapy. Here a mathematical model was developed and fitted to frequent HDV and HBsAg kinetic data from 10 patients during the first 28 weeks of pegylated-interferon-α2a (peg-IFN) therapy. Three patients achieved a complete virological response (CVR), defined as undetectable HDV 6 months after treatment stopped with loss of HBsAg and anti-HBsAg seroconversion. After initiation of therapy a median delay of 9 days (interquartile range IQR:[5;15]) was observed with no significant changes in HDV level. Thereafter, HDV declined in a biphasic manner, where a rapid first-phase lasting for 25 days (IQR:[23;58]) was followed by a slower or plateau second-phase. The model predicts that the main effect of peg-IFN is to reduce HDV production/release with a median effectiveness of 96% (IQR:[93;99.8]). Median serum HDV half-life (t1/2) was estimated to 2.9 days (IQR:[1.5;5.3]) with pretreatment production and clearance of about 1010 (IQR:[109.8-1010.8]) virions/day. None of the patients with flat 2nd phase in HDV achieved CVR. HBsAg kinetics of decline paralleled the second-phase of HDV decline consistent with HBsAg-productive-infected cells being the main source of production of HDV, with a median t1/2 of 135 days (IQR:[20-460]. The interferon lambda-3 polymorphism (rs12979860) was not associated with kinetic parameters. Conclusions Modeling results provide insights into HDV-host dynamics, the relationship between serum HBsAg levels and HBsAg-infected cells, IFN's mode of action and its effectiveness. The observation that a flat second phase in HDV and HBsAg kinetics was associated with failure to achieve CVR provides the basis to develop early stopping rules during peg-IFN treatment in HDV-infected patients.

    Adjuvant chemo- and/or radiotherapy is applied in a majority of patients treated for early stage breast cancer, although only a small percentage of these individuals are at high risk of metastasis or recurrence. Hence, knowledge of the biomarkers associated with the risk of disease progression might facilitate the planning of an optimal therapy and protect many patients from the toxicity of unnecessary treatment. In this study, we characterized the serum proteome of patients diagnosed with early-stage breast cancer, exhibiting either no evidence of disease five years after the end of therapy or suffering from metastasis, relapse or a second cancer during the corresponding follow-up. Samples collected before treatment and one year after the end of therapy, when no clinical symptoms of a treatment failure was evidenced, were analyzed using two classical proteomics approaches: LC-MS/MS and 2D-PAGE. A total of 42 proteins with relative quantities that were significantly different between pre- and post-treatment samples were identified in either group of patients; however, the observed changes were more frequent in the treatment-failure group. Among the posttreatment samples, 30 proteins were upregulated, and 10 proteins were downregulated, while 11 proteins were upregulated, and eight proteins were downregulated in the control group. Moreover, several proteins exhibited different patterns of changes in both groups of patients. For example, haptoglobin expression increased in the treatment-failure group but decreased in the control group (this pattern of changes was confirmed using an immunoassay). Notably, proteins affected in posttreatment samples in either group of patients could be associated with different molecular and cellular functions, including angiogenesis, blood coagulation and wound healing in the treatment-failure group and cell adhesion and cell death in the control group.

  12. Overexpression of serum response factor in astrocytes improves neuronal plasticity in a model of early alcohol exposure.

    Neuronal plasticity deficits underlie many of the cognitive problems seen in fetal alcohol spectrum disorders (FASD). We have developed a ferret model showing that early alcohol exposure leads to a persistent disruption in ocular dominance (OD) plasticity. Recently, we showed that this deficit could be reversed by overexpression of serum response factor (SRF) in the primary visual cortex during the period of monocular deprivation (MD). Surprisingly, this restoration was observed throughout the extent of visual cortex and most of the cells transfected by the virus were positive for the astrocytic marker GFAP rather than the neuronal marker NeuN. Here we test whether overexpression of SRF exclusively in astrocytes is sufficient to restore OD plasticity in alcohol-exposed ferrets. To accomplish that, first we exposed cultured astrocytes to Sindbis viruses carrying either a constitutively active form of SRF (SRF+), a dominant negative (SRF-) or control Green Fluorescent Protein (GFP). After 24h, these astrocytes were implanted in the visual cortex of alcohol-exposed animals or saline controls one day before MD. Optical imaging of intrinsic signals showed that alcohol-exposed animals that were implanted with astrocytes expressing SRF, but not SRF- or GFP, showed robust restoration of OD plasticity in all visual cortex. These findings suggest that overexpression of SRF exclusively in astrocytes can improve neuronal plasticity in FASD.

    Serum IgD levels in individuals infected with the human immunodeficiency viruses (HIV) were studied as a means of monitoring the character and timing of B cell activation in individuals with this infection. Significantly increased levels of IgD were characteristic of homosexual men who were HIV seropositive but asymptomatic or mildly symptomatic. The hyper IgD globulinaemia became progressively more pronounced in patients with increasingly severe infection and reached its most marked level in patients with AIDS-related complex (ARC). In ARC patients, IgD levels were increased 8.8-fold above normal which was disproportionately greater than the 2.4-fold increase in IgG, the 1.8-fold increase in IgA and the 1.6-fold increase in IgM. IgD levels declined in AIDS patients (although remained elevated compared to controls). The data suggest that an unusual type of B cell activation is responsible for the unique pattern of hypergammaglobulinaemia seen in this disease and that the B cell activation occurs early in the pathogenesis of HIV infection, often before development of symptoms, and continues throughout the course of infection.

Significantly increased levels of IgD were characteristic of homosexual men who were HIV seropositive but asymptomatic or mildly symptomatic. The hyper IgD globulinaemia became progressively more pronounced in patients with increasingly severe infection and reached its most marked level in patients with AIDS-related complex (ARC). In ARC patients, IgD levels were increased 8.8-fold above normal which was disproportionately greater than the 2.4-fold increase in IgG, the 1.8-fold increase in IgA and the 1.6-fold increase in IgM. IgD levels declined in AIDS patients (although remained elevated compared to controls). The data suggest that an unusual type of B cell activation is responsible for the unique pattern of hypergammaglobulinaemia seen in this disease and that the B cell activation occurs early in the pathogenesis of HIV infection, often before development of symptoms, and continues throughout the course of infection.

    Specimen collection is an integral component of clinical research. Specimens from subjects with various stages of cancers or other conditions, as well as those without disease, are critical tools in the hunt for biomarkers, predictors, or tests that will detect serious diseases earlier or more readily than currently possible. Analytic methodologies evolve quickly. Access to high-quality specimens, collected and handled in standardized ways that minimize potential bias or confounding factors, is key to the "bench to bedside" aim of translational research. It is essential that standard operating procedures, "the how" of creating the repositories, be defined prospectively when designing clinical trials. Small differences in the processing or handling of a specimen can have dramatic effects in analytical reliability and reproducibility, especially when multiplex methods are used. A representative working group, Standard Operating Procedures Internal Working Group (SOPIWG), comprised of members from across Early Detection Research Network (EDRN) was formed to develop standard operating procedures (SOPs) for various types of specimens collected and managed for our biomarker discovery and validation work. This report presents our consensus on SOPs for the collection, processing, handling, and storage of serum and plasma for biomarker discovery and validation.

    Renal cell carcinoma (RCC) is frequently diagnosed at advanced stages of disease, although early diagnosis has much favorable prognosis. This study assessed aberrant expression of cytosolic carboxypeptidase 6 (CCP6) leading to accumulation of serum polyglutamylated DNAJC7 as a biomarker for early RCC detection. A total of 835 RCCs, 143 chronic nephritis, 170 kidney stones and 415 health controls were collected for qRT-PCR, immunohistochemistry and Western blot analysis of CCP6 expression and mass spectrometry of DNAJC7 and polyglutamylated DNAJC7. The data showed that CCP6 expression was significantly decreased in 30 RCC tissues and that mass spectrometric and pull-down analysis identified DNAJC7 as a substrate of CCP6 and showed upregulated polyglutamylated-DNAJC7 (polyE-DNAJC7) in sera of RCC patients. The electrochemiluminescence immunoassay of large-scale serum samples from multi-institutes further confirmed the remarkable increase of polyE-DNAJC7 in 805 RCCs compared to that of 385 healthy controls (p < 0.001), 128 patients with chronic nephritis (p < 0.001), and 153 with kidney stone (p < 0.001). Serum level of DNAJC7-polyE protein was also associated with advanced RCC stage and grade in 805 patients. The data from the current study for the first time demonstrated increased serum polyglutamylated DNAJC7 as a potential biomarker for RCC early detection and association with advanced tumor stages and grade, which provides support of further polyglutamylation research in RCC.

    In order to determine whether microRNA (miR)-300 is a diagnostic and prognostic biomarker in osteosarcoma, the miR-300 levels in serum of 114 osteosarcoma patients and 114 healthy controls were compared, followed by serum analysis of the differences between the pre-operative and post-operative sera of these osteosarcoma patients. It was observed that the concentration levels of miR-300 in the serum of osteosarcoma patients was significantly higher than those in the serum of healthy controls (P<0.01). Furthermore, the concentration levels of miR-300 in the post-operative serum were significantly reduced when compared with the pre-operative serum levels (P<0.001). High miR-300 levels in serum correlated significantly with clinical stage, distant metastasis and poor survival of osteosarcoma patients. Notably, serum miR-300 was an independent prognostic marker for osteosarcoma. In conclusion, our results suggested that serum miR-300 may be a potential and useful noninvasive biomarker for the early detection of osteosarcoma.

    Cell-mediated immunity plays an important role in the pathobiology of tuberculosis (TB). The ligands for CXC chemokine receptor 3 (CXCR3) activate the T-helper type 1 lymphocyte pathway. The CXCR3 ligands are reportedly useful clinical markers for the diagnosis and follow-up of TB. The objective of this study was to assess the utility of CXCR3 ligands for evaluating early treatment responses in TB.We recruited 88 patients who underwent antituberculous chemotherapy. The serum levels of interferon (IFN)-γ and the CXCR3 ligands CXCL9 (monokine induced by IFN-γ [MIG]), CXCL10 (IFN-γ-inducible 10-kDa protein [IP-10]), and CXCL11 (IFN-inducible T-cell α chemoattractant [I-TAC]) were measured before and 2 months after the start of treatment. Treatment responses were divided into "fast" and "slow" based on the clinical, radiological, and bacteriological improvement at 2 months. A change in level of 20% or more at 2 months was defined as "significant."In patients with treatment success, 58 patients exhibited a fast response and 20 patients exhibited a slow response. Treatment failure occurred in 5 patients, and the diagnoses were changed to non-TB diseases in 5 patients. The levels of all CXCR3 ligands significantly decreased in the fast-response group (P < 0.01) but did not decrease in the other groups. IFN-γ levels showed no significant changes. The ability of significant decreases in marker levels to predict a fast response was evaluated. CXCL9 showed a sensitivity of 83%, and CXCL10 showed a specificity of 100%. Use of various combinations of CXCR3 ligands resulted in improvements in sensitivity (88%-93%), while specificity (92%-96%) was similar to that using single CXCR3 ligands. The decreases in CXCR3 ligand levels were less marked in the 2-month Mycobacterium tuberculosis culture-positive group than in the culture-negative group. There were significant differences in treatment outcomes in terms of 2-month culture positivity (P < 0.001), the significance

    The diagnosis of early, small and alpha-fetoprotein (AFP)-negative primary hepatic carcinomas (PHCs) remains a significant challenge. We developed a simple and robust approach to noninvasively detect these PHCs. A rapid, high-throughput and single-tube method was firstly developed to measure serum autofluorescence and cell-free DNA (cfDNA)-related fluorescence using a real-time PCR system, and both types of serum fluorescence were measured and routine laboratory data were collected in 1229 subjects, including 353 PHC patients, 331 liver cirrhosis (LC) patients, 213 chronic hepatitis (CH) patients and 332 normal controls (NC). The results showed that fluorescence indicators of PHC differed from those of NC, CH and LC to various extents, and all of them were not associated with age, gender, or AFP level. The logistic regression models established with the fluorescence indicators alone and combined with AFP, hepatic function tests and blood cell analyses were valuable for distinguishing early, small, AFP-negative and all PHC from LC, CH, NC and all non-PHC, with areas under the receiver operating characteristic curves 0.857–0.993 and diagnostic accuracies 80.2–97.7%. Conclusively, serum autofluorescence and cfDNA-related fluorescence are able to be rapidly and simultaneously measured by our simple method and valuable for diagnosing early, small and AFP-negative PHCs, especially integrating with AFP and conventional blood tests.

Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

    In the postoperative period, 47% to 75% of the patients report some degree of pain. This study aimed to evaluate pain in the pre and postoperative period of patients submitted to craniotomy. This prospective research was carried out at the neurosurgery unit of a large Brazilian hospital. For a quantitative evaluation of pain, the verbal numeric 0-10 rating scale was used. Forty patients with a mean age of 36 years were evaluated. In the preoperative period, 34 (85%) patients indicated headache as the main cause of pain. In the postoperative period, 37 (93%) patients complained of pain while three (7%) reported absence of pain. Pain peaks were observed on the 2nd postoperative day, when 12 (32%) of the patients reported severe pain and 10 (27%) moderate pain. Absence of severe pain occurred after the 8th postoperative day. It was concluded that protocols of analgesia in craniotomy are needed, such as training nurses to better evaluate and handle pain.

    Circulating microRNAs are deregulated in liver fibrosis and hepatocellular carcinoma (HCC) and are candidate biomarkers. This study investigated the potential of serum microRNAs; miR-19a, miR-296, miR-130a, miR-195, miR-192, miR-34a, and miR-146a as early diagnostic biomarkers for hepatitis C virus (HCV)-related HCC. As how these microRNAs change during liver fibrosis progression is not clear, we explored their serum levels during fibrosis progression in HCV-associated chronic liver disease (CLD) and if they could serve as non-invasive biomarkers for fibrosis progression to HCC. 112 Egyptian HCV-HCC patients, 125 non-malignant HCV-CLD patients, and 42 healthy controls were included. CLD patients were subdivided according to Metavir fibrosis-scoring. Serum microRNAs were measured by qRT-PCR custom array. Serum microRNAs were deregulated in HCC versus controls, and except miR-130a, they were differentially expressed between HCC and CLD or late fibrosis (F3-F4) subgroup. Serum microRNAs were not significantly different between individual fibrosis-stages or between F1-F2 (early/moderate fibrosis) and F3-F4. Only miR-19a was significantly downregulated from liver fibrosis (F1-F3) to cirrhosis (F4) to HCC. Individual microRNAs discriminated HCC from controls, and except miR-130a, they distinguished HCC from CLD or F3-F4 patients by receiver-operating-characteristic analysis. Multivariate logistic analysis revealed a panel of four microRNAs (miR-19a, miR-195, miR-192, and miR-146a) with high diagnostic accuracy for HCC (AUC = 0.946). The microRNA panel also discriminated HCC from controls (AUC = 0.949), CLD (AUC = 0.945), and F3-F4 (AUC = 0.955). Studied microRNAs were positively correlated in HCC group. miR-19a and miR-34a were correlated with portal vein thrombosis and HCC staging scores, respectively. In conclusion, studied microRNAs, but not miR-130a, could serve as potential early biomarkers for HCC in high-risk groups, with miR-19a as a biomarker for liver fibrosis

    Systemic lupus erythematosus (SLE) is a common but severe autoimmune systemic inflammatory disease. Lupus nephritis (LN) is a serious complication of SLE,affecting up to 70% of SLE patients. Circulating microRNAs (miRNA) are emerging as biomarkers for pathological conditions and play significant roles in intercellular communication. In present research, serum samples from healthy control, early and late stage LN patients were used to analyze the expression profile of miRNAs by microarray. Subsequent study demonstrated that miR-130b-3p in serum of patients with early stage LN were significantly up-regulated when compared with healthy controls. In addition,we have also observed that the expression of a large amount of circulating microRNAs significantly decreased in patients with late stage LN. The further analysis found that the expression of serum miR-130b-3p was positively correlated with 24-hour proteinuria and renal chronicity index in patients with early stage LN.Transfection of renal tubular cellline(HK-2)with miR-130b-3p mimics can promote epithelial-mesenchymal transition (EMT). The opposite effects were observed when transfected with miR-130b-3p inhibitors. MiR-130b-3p negatively regulated ERBB2IP expression by directly targeting the 3‧-UTR of ERBB2IP The circulating miR-130b-3p might serve as a biomarker and play an important role in renal damage in early stage LN patients.

    The goal of postoperative management is to promote early mobility and avoid postoperative complications, recognizing the potentially devastating impact of complications on elderly patients with hip fracture. The recommended approach involves early mobilization; freedom from tethers (indwelling urinary catheters and other devices); effective pain control; treating malnutrition; preventing pressure ulcers; reducing risk for pulmonary, urinary, and wound infections; and managing cognition. This carefully structured and patient-centered management provides older, vulnerable patients their best chance of returning to their previous level of functioning as quickly and safety as possible.

    Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

    Chronic postoperative pain remains a frequent pathology whose global impact approximates 20 and 30% and accounts for 20% of the consultations in a pain center. Risk factors consider firstly each patient's feature and comorbidity and also different surgical procedures with their technical approach. Neuropathic pain compared to nociceptive pain is a great component in the postoperative period and needs to be recognized by specific tests (DN4). Pain prevention involves risk factors' detection, appropriate anesthetic support and effective postoperative pain management. Treatment is based on the type of pain and includes a multimodal analgesia with interventional pain therapy.

    Proteomic profiling of serum is a powerful technique to identify differentially expressed proteins that can serve as biomarkers predictive of disease onset. In this study, we utilized 2D gel analysis followed by MALDI-TOF mass spectrometry analysis to identify putative serum biomarkers for autoimmune type 1 diabetes (T1D) in BioBreeding Diabetes Resistant (BBDR) rats induced to express disease. Treatment with toll-like receptor 3 (TLR3) ligand, polyinosinic:polycytidilic acid (pIC), plus infection with Kilham rat virus (KRV), a rat parvovirus, results in nearly 100% of young BBDR rats becoming diabetic within 11–21 days. Sera collected from pre-diabetic rats at early time points following treatment with pIC + KRV were analyzed by 2D gel electrophoresis and compared with sera from control rats treated with PBS, pIC alone, or pIC + H1, a non-diabetogenic parvovirus. None of the latter three control treatments precipitates T1D. 2D gel analysis revealed that haptoglobin, an acute phase and hemoglobin scavenger protein, was differentially expressed in the sera of rats treated with pIC + KRV relative to control groups. These results were confirmed by Western blot and ELISA studies that further validated haptoglobin levels as being differentially increased in the sera of pIC + KRV treated rats relative to controls during the first week following infection. Early elevations in serum haptoglobin were also observed in LEW1.WR1 rats that became diabetic following infection with rat cytomegalovirus (RCMV). The identification and validation of haptoglobin as a putative serum biomarker for autoimmune T1D in rats now affords us the opportunity to test the validity of this protein as a biomarker for human T1D, particularly in those situations where viral infection is believed to precede onset of disease.

    The present work deals with the evaluation of a high-performance liquid chromatography laser-induced fluorescence (HPLC-LIF) technique developed in our laboratory for early detection of oral cancer from protein profiles of body fluids. The results show that protein profiles of serum samples from a given class of samples, say, normal, premalignant, or malignant, are statistically very close to each other, while profiles of members of any class are significantly different from other classes. The performance of the technique is evaluated by the use of sensitivity and specificity pairs, receiver operating characteristic (ROC) analysis, and Youden's Index. The technique uses protein profile differences in serum samples, registered by the HPLC-LIF technique. The study is carried out using serum samples from volunteers diagnosed as normal or premalignant clinically, and as malignant by histopathology. The specificities and sensitivities of the HPLC-LIF method at an ideal threshold (M-distance = 2) for normal, malignant, and premalignant classes are 100, 69.5, and 61.5%, and 86.5, 87.5, and 87.5% respectively.

    Despite the introduction of high-technology methods of detection and diagnosis, screening of primary liver cancer (PLC) remains imperfect. To diagnosis PLC earlier, Surface-enhanced Raman spectroscopy (SERS) coupled with cellulose-acetate membrane electrophoresis were introduced to separate human serum albumin and SERS spectra. Three groups (15 normal persons' samples, 17 hepatitis/cirrhosis samples, 15 cases of PLC) of serum albumin were tested. Silver colloid was used to obtain SERS spectra of human serum albumin. Principal component analysis (PCA) and linear discriminant analysis (LDA) were also employed for statistical analysis. The mean Raman spectra of three groups and the difference spectra of any two suggested that the albumin has changed in liver patients. Compared to normal groups, some Raman peaks have shifted or even disappeared in hepatitis/cirrhosis and PLCs groups. The sensitivity and specificity between PLCs and normal groups is 80% and 93.3%. Among hepatitis/cirrhosis and normal groups, the sensitivity is 88.2% and specificity is also 93.3%. Besides, the sensitivity and specificity between PLCs and hepatitis/cirrhosis groups is 86.7% and 76.5%. All the above data and results indicated that early screening of PLC is potential by SERS in different stages of liver disease before cancer occurs.

    As neurotrophic factors play an important role in development and maintenance of global central nervous system (CNS) function, we supposed that glial cell-line derived neurotrophic factor (GDNF), which has been extensively studied for its survival promoting effects especially concerning catecholaminergic neurons, also plays a significant role in neurodegenerative disease characterized mainly by damage of cholinergic CNS neurons like AD. Here we compared GDNF concentrations in serum and cerebrospinal fluid (CSF) of patients with probable Alzheimer's disease (AD) and normal controls (NC). While GDNF concentrations in CSF were significantly increased in patients with AD (291.7 +/- 85.8 pg/ml) compared with NC subjects (218.7 +/- 93.3 pg/ml, p = 0.012), GDNF concentration of AD patients (486.5 +/- 72.3 pg/ml) in serum were significantly decreased compared with the NC group (711.5 +/- 186.5 pg/ml, p < 0.001). Increased GDNF in CSF of AD might be due to an upregulated expression in CNS as an adaptive process of the impaired brain to enhance neurotrophic support at least in early stages of disease and/or impairment of CSF turnover. Decreased serum concentration of GDNF might be related to altered function of the blood brain barrier thus disturbing clearance or facilitating passover of potentially harmful metabolites.

    We applied multiplex-tandem PCR (MT-PCR) to 255 EDTA whole-blood specimens, 29 serum specimens, and 24 plasma specimens from 109 patients with Candida bloodstream infection (candidemia) to determine whether a diagnosis could be expedited in comparison with the time to diagnosis by the use of standard blood culture. Overall, the MT-PCR performed better than blood culture with DNA extracted from whole blood from 52/74 (70%) patients, accelerating the time to detection (blood culture flagging) and determination of the pathogenic species (by use of the API 32C system [bioMérieux, Marcy l'Etoile, France]) by up to 4 days (mean, 2.2 days; range, 0.5 to 8 days). Candida DNA was detected more often in serum (71%) and plasma (75%) than in whole blood (54%), although relatively small numbers of serum and plasma specimens were tested. The sensitivity, specificity, positive predictive value, and negative predictive value of the assay with whole blood were 75%, 97%, 95%, and 85%, respectively. Fungal DNA was not detected by MT-PCR in 6/24 (25%) whole-blood samples drawn simultaneously with the positive blood culture sample. MT-PCR performed better with whole-blood specimens stored at -20 degrees C (75%) and when DNA was extracted within 1 week of sampling (66%). The molecular and culture identification results correlated for 61 of 66 patients (92%); one discrepant result was due to misidentification by culture. All but one sample from 53 patients who were at high risk of candidemia but did not have proven disease were negative by MT-PCR. The results demonstrate the good potential of MT-PCR to detect candidemia, to provide Candida species identification prior to blood culture positivity, and to provide improved sensitivity when applied to with serum and plasma specimens.

    Abstract The serum C-reactive protein (CRP) is an inflammatory marker. The aim of the present study was to elucidate whether CRP could serve as a potential surrogate marker for 30-day mortality in hospitalized patients with HBV-related decompensated cirrhosis (HBV-DeCi). This was a retrospective cohort study that included 140 patients with HBV-DeCi. All patients were followed up for 1-month. A panel of clinical and biochemical variables were analyzed for potential associations with outcomes using multiple regression models. The serum CRP was significantly higher in nonsurviving patients than in surviving patients. Multivariate analysis demonstrated that CRP levels (odds ratio: 1.047, P = 0.002) and the model for end-stage liver disease score (odds ratio: 1.370, P = 0.001) were independent predictors for mortality. Serum CRP is a simple marker that may serve as an additional predictor of 1-month mortality in hospitalized patients with HBV-DeCi. PMID:28121954

    Despite the well-accepted notion that early maternal influences persist beyond fetal life and may underlie many adult diseases, the risks imposed by the maternal environment on breast cancer development and underlying biological mechanisms remain poorly understood. In this study, we investigated whether early exposure to blueberry (BB) via maternal diet alters oncogene Wnt1-induced mammary tumorigenesis in offspring. Wnt1-transgenic female mice were exposed to maternal Casein (CAS, control) or blueberry-supplemented (CAS + 3%BB) diets throughout pregnancy and lactation. Offspring were weaned to CAS and mammary tumor development was followed until age 8 months. Tumor incidence and latency were similar for both groups; however, tumor weight at killing and tumor volume within 2 weeks of initial detection were lower (by 50 and 60%, respectively) in offspring of BB- versus control-fed dams. Dietary BB exposure beginning at weaning did not alter mammary tumor parameters. Tumors from maternal BB-exposed offspring showed higher tumor suppressor (Pten and Cdh1) and lower proproliferative (Ccnd1), anti-apoptotic (Bcl2) and proangiogenic (Figf, Flt1 and Ephb4) transcript levels, and displayed attenuated microvessel density. Expression of Pten and Cdh1 genes was also higher in mammary tissues of maternal BB-exposed offspring. Mammary tissues and tumors of maternal BB-exposed offspring showed increased chromatin-modifying enzyme Dnmt1 and Ezh2 transcript levels. Body weight, serum insulin and serum leptin/adiponectin ratio were lower for maternal BB-exposed than control tumor-bearing offspring. Tumor weights and serum insulin were positively correlated. Results suggest that dietary influences on the maternal environment contribute to key developmental programs in the mammary gland to modify breast cancer outcome in adult progeny.

  18. Serum levels of osteoprotegerin and receptor activator of nuclear factor -κB ligand in children with early juvenile idiopathic arthritis: a 2-year prospective controlled study

    2010-01-01

    Background The clinical relevance of observations of serum levels of osteoprotegerin (OPG) and receptor activator of nuclear factor -κB ligand (RANKL) in juvenile idiopathic arthritis (JIA) is not clear. To elucidate the potential role of OPG and RANKL in JIA we determined serum levels of OPG and RANKL in patients with early JIA compared to healthy children, and prospectively explored changes in relation to radiographic score, bone and lean mass, severity of the disease, and treatment. Methods Ninety children with early oligoarticular or polyarticular JIA (ages 6-18 years; mean disease duration 19.4 months) and 90 healthy children individually matched for age, sex, race, and county of residence, were examined at baseline and 2-year follow-up. OPG and RANKL were quantified by enzyme-immunoassay. Data were analyzed with the use of t-tests, ANOVA, and multiple regression analyses. Results Serum OPG was significantly lower in patients than controls at baseline, and there was a trend towards higher RANKL and a lower OPG/RANKL ratio. Patients with polyarthritis had significantly higher increments in RANKL from baseline to follow-up, compared to patients with oligoarthritis. RANKL was a significant negative predictor for increments in total body lean mass. Patients who were receiving corticosteroids (CS) or disease-modifying antirheumatic drugs (DMARDs) at follow-up had higher OPG/RANKL ratio compared with patients who did not receive this medication. Conclusions The data supports that levels of OPG are lower in patients with JIA compared to healthy children, and higher levels of RANKL is associated with more serious disease. RANKL was a significant negative predictor of lean mass in patients with JIA. The OPG/RANKL ratio was higher in patients on DMARDs or CS treatment. PMID:21134287

    Background: Total thyroidectomy (TT) is a commonly performed surgery and postoperative hypocalcemia is a major detriment to early discharge. The aim of this randomized controlled trial was to ascertain the usefulness of routine pre- and post-operative calcium and Vitamin D supplementation in prevention of hypocalcemia after TT. Materials and Methods: Sixty consecutive patients who underwent total or near TT from February 2013 to August 2014 were included in the study. They were randomly divided into two groups - Group 1 received oral calcium (500 mg every 6 h) and Vitamin D (calcitriol 0.25 mcg every 6 h) 7 days before and 7 days after the surgery; and Group 2 did not receive supplementation. Symptoms and signs of hypocalcemia were monitored. Calcium profile was measured pre- and post-operatively at 6, 12, 24, 48, 72 h, and on 30th day. Hypocalcemia after surgery was either symptomatic or laboratory documented. Serum calcium level ≤ 8.5 mg/dl was considered as laboratory hypocalcemia. Results: Twelve patients from Group 2, and 3 patients from Group 1 developed symptomatic hypocalcemia (P < 0.01). Laboratory hypocalcemia within postoperative 24 h was comparable between two groups, but more patients of Group 2 compared to Group 1 developed hypocalcemia at 48 h (6 and 13, respectively; P = 0.04) and at 72 h after surgery (5 and 14, respectively; P = 0.01). Twenty-four hours postoperative serum calcium level was significantly associated with grade of goiter, preoperative calcium, and nature of thyroid disease (benign or malignant). On multiple linear regression analysis, preoperative serum calcium was only independent variable significantly associated with development of 24 h post-TT hypocalcemia. Conclusion: Routine pre- and post-TT calcium and Vitamin D supplementation can significantly reduce postoperative hypocalcemia. PMID:28217498

    The hormone progesterone is essential for proper embryonic development. The objective of this study was to examine the relationship between recipient serum concentrations of progesterone, at the time of embryo transfer and at conceptus recovery, on conceptus development from in vivo- or in vitro-produced embryos. Embryos were produced in vivo by superovulation of Holstein cows (IVO; n = 17) or in vitro with either serum-containing (IVPS; n = 27) or serum-restricted medium (IVPSR; n = 34). Single grade I blastocysts from each embryo production system were transferred into heifers on day 7 of development. Conceptuses were recovered on day 17 of gestation and classified as complete, degenerated, or no conceptus. Compared with the IVO group, in vitro-produced embryos had more (P = 0.055) degenerated conceptuses (IVO, 0%; IVPS, 18.5%; and IVPSR, 20.6%). There were no differences in progesterone concentrations at the time of transfer when recipients received either male or female embryos (P > 0.05). Progesterone concentrations in recipients receiving in vivo-produced embryos were higher (P < 0.05; 3.74 ± 0.4 ng/mL; least-squares mean ± standard error of the mean) on day 7 compared with those receiving in vitro-produced embryos (IVPS, 2.4 ± 0.2; IVPSR, 2.58 ± 0.3 ng/mL). However, there was no difference in progesterone concentration on day 7 between treatment groups for heifers from which short conceptuses (≤194 mm) were recovered on day 17. In contrast, when longer (>194 mm) conceptuses were recovered on day 17, heifers receiving in vitro-produced embryos had lower (P = 0.05) serum concentrations of progesterone on day 7 compared with those receiving in vivo-produced embryos (IVPS, 2.2 ± 0.5; IVPSR, 2.3 ± 0.5; IVO, 3.9 ± 0.5 ng/mL). In conclusion, differences in autonomy may exist between in vitro- and in vivo-produced embryos during the period of conceptus elongation with in vitro-produced embryos relying more on intrinsic factors to influence elongation.

    Serum protein profiles of patients with bacterial sepsis from the day of diagnosis until recovery/mortality were compared from early to late stages in response to severe sepsis using two dimensional electrophoresis. The proteins exhibiting changes during the course of sepsis (20‑28 day mortality) were selected and identified by matrix‑assisted laser desorption ionization‑time of flight‑tandem mass spectrometry. Among the proteins identified, haptoglobin (Hp), transthyretin (TTR), orosomucoid 1/α1 acid glycoprotein (ORM1), α1 antitrypsin (A1AT), serum amyloid A (SAA) and S100A9 exhibited differential expression patterns between survivors (S; n=6) and non‑survivors (NS; n=6), particularly during the early stages of sepsis. Expression factors (EFs), taken as the ratio between the NS and S during early stages, showed ratios of Hp, 0.39 (P≤0.012); TTR, 3.96 (P≤0.03); ORM1, 0.69 (P≤0.79); A1AT, 0.92 (P≤0.87) and SAA, 0.69 (P≤0.01). S100A9, an acute phase protein, exhibited an EF ratio of 1.68 (P≤0.004) during the end stages of sepsis. A delayed rise in levels was observed in Hp, A1AT, ORM1, S100A9 and SAA, whereas TTR levels increased during the early stages of sepsis in NS. Analysis of inflammatory responses in the early stages of sepsis revealed increased mRNA expression in leukocytes of interleukin (IL)‑6 (EF, 2.50), IL‑10 (EF, 1.70) and prepronociceptin (EF, 1.6), which is a precursor for nociceptin in NS compared with S, and higher Toll‑like receptor‑4 (EF, 0.30) levels in S compared with NS. Therefore, a weaker acute phase response in the early stages of sepsis in NS, combined with an inefficient inflammatory response, may contribute to sepsis mortality.

    We hypothesized the levels of free light chains obtained before and after autologous stem cell transplantation can be useful in predicting transplantation outcome. We analyzed 70 multiple myeloma patients. Abnormal free light chain ratios before stem cell transplantation were found to be associated early progression, although without any impact on overall survival. At day +30, the normalization of levels of involved free light chain related with early progression. According to these results almost one-third reduction of free light chain levels can predict favorable prognosis after autologous stem cell transplantation.

    Background: A recent study reported a positive association between elevated serum levels of angiopoietin-like protein 2 (ANGPTL2) and the development of type 2 diabetes in a general population. However, the relationship of serum ANGPTL2 levels with the risk of developing gestational diabetes mellitus (GDM) has not been reported to date. The aim of this study was to investigate the change of maternal serum ANGPTL2 concentrations in the first trimester of pregnancy and to determine whether ANGPTL2 is a biomarker for subsequent GDM development. Methods: We conducted a prospective, nested case-control study in a pregnancy cohort. First-trimester ANGPTL2 levels were measured using a high-resolution assay in 89 women who subsequently developed GDM and in a random sample of 177 women who remained euglycemic throughout the pregnancy. Median ANGPTL2 levels were compared using Mann-Whitney U-test. Logistic regression was used to compute unadjusted and multivariable-adjusted odds ratios for developing GDM among ANGPTL2 quartiles. Results: The serum levels of ANGPTL2 was higher in women with GDM than that in women without GDM (3.06 [2.59, 3.65] ng/ml vs. 2.46 [2.05, 2.96] ng/ml, P = 0.003). Fasting blood glucose was higher in women with GDM than that in women without GDM (5.0 ± 0.9 mmol/L vs. 4.4 ± 0.6 mmol/L, P < 0.001). Glucose challenge test showed that the blood glucose was higher in women with GDM than that in women without GDM (9.1 ± 3.5 mmol/L vs. 6.2 ± 1.2 mmol/L, P < 0.001). A multivariate model adjusted for baseline characteristics, medical complications, and gestational characteristics revealed that the risk of developing GDM among women in Q4 compared with Q1 was 2.90-fold more likely to develop GDM later in pregnancy. Conclusions: At 11–13 weeks in pregnancies that develop GDM, the serum concentration of ANGPTL2 is increased, and it can be combined with maternal factors to provide effective early screening for GDM.

    Relief of acute pain during the immediate postoperative period is an important task for anaesthetists. Morphine is widely used to control moderate-to-severe postoperative pain and the use of small i.v. boluses of morphine in the post-anaesthesia care unit allows a rapid titration of the dose needed for adequate pain relief. The essential principle of a titration regimen must be to adapt the morphine dose to the pain level. Although morphine would not appear to be the most appropriate choice for achieving rapid pain relief, this is the sole opioid assessed in many studies of immediate postoperative pain management using titration. More than 90% of the patients have pain relief using a protocol of morphine titration and the mean dose required to obtain pain relief is 12 (7) mg, after a median of four boluses. Sedation is frequent during i.v. morphine titration and should be considered as a morphine-related adverse event and not evidence of pain relief. The incidence of ventilatory depression is very low when the criteria to limit the dose of i.v. morphine are enforced. Morphine titration can be used with caution in elderly patients, in children, or in obese patients. In practice, i.v. morphine titration allows the physician to meet the needs of individual patients rapidly and limits the risk of overdose making this method the first step in postoperative pain management.

    Between 10 and 40% of patients who have undergone a radical prostatectomy may have a biologic recurrence. Local or distant failure represents the possible patterns of relapse. Patients at high-risk for local relapse have extraprostatic disease, positive surgical margins or seminal vesicles infiltration or high Gleason score at pathology. Three phase-III randomized clinical trials have shown that, for these patients, adjuvant irradiation reduces the risk of tumoral progression without higher toxicity. Salvage radiotherapy for late relapse allows a disease control in 60-70% of the cases. Several research in order to improve the therapeutic ratio of the radiotherapy after prostatectomy are evaluate in the French Groupe d'Étude des Tumeurs Urogénitales (Gétug) and of the French association of urology (Afu). The Gétug-Afu 17 trial will provide answers to the question of the optimal moment for postoperative radiotherapy for pT3-4 R1 pN0 Nx patients, with the objective of comparing an immediate treatment to a differed early treatment initiated at biological recurrence. The Gétug-Afu 22 questions the place of a short hormonetherapy combined with image-guided, intensity-modulated radiotherapy (IMRT) in adjuvant situation for a detectable prostate specific antigen (PSA). The implementation of a multicenter quality control within the Gétug-Afu in order to harmonize a modern postoperative radiotherapy will allow the development of a dose escalation IMRT after surgery.

    The authors hypothesized that the use of incentive spirometry by orthopedic patients is less than the recommended level and is affected by patient-related factors and type of surgery. To determine its postoperative use, the authors prospectively surveyed all patients in their institution's general orthopedic ward who had undergone elective spine surgery or total knee or hip arthroplasty during a consecutive 3-month period in 2010, excluding patients with postoperative delirium or requiring a monitored bed. All 182 patients (74 men, 108 women; average age, 64.5 years; range, 32-88 years; spine group, n=55; arthroplasty group, n=127), per protocol, received preoperative spirometry education by a licensed respiratory therapist (recommended use, 10 times hourly) and reinforcement education by nurses. Patients were asked twice daily (morning and evening) regarding their spirometry use during the previous 1-hour period by a registered nurse on postoperative days 1 through 3. All data were collected by the same 2 nurses using the same standardized questionnaire. Spirometry use was correlated with surgery type, postoperative day/time, and patient's age and sex. Student's t test, Spearman test, and one-way analysis of variance were used to compare differences (P<.05). Spirometry use averaged 4.1 times per hour (range, 0-10 times). No statistical correlations were found between spirometry use and age. Sex did not influence spirometry use. The arthroplasty group reported significantly higher use than did the spine group: 4.3 and 3.5 times per hour, respectively. Mean use increased significantly between postoperative days 1, 2, and 3.

    Fluoro-edenite (FE) is a natural mineral asbestos-like fibrous species first isolated in Biancavilla, Sicily. In order to clarify potential involvement of IL-18 in the pathogenesis of FE-induced chest abnormalities, we analyzed IL-18 serum levels in FE-exposed workers (FEEW) and correlated them with pleural and parenchymal abnormalities. A total of 21 FEEWs, residing in Biancavilla for >30 years, with a working seniority of 17 ± 6.1 years were examined. High-resolution computed tomography scans revealed low grade of fibrosis in 8 (38%) FEEWs, and pleural plaques (PPs) in 13 (62%) FEEWs. The mean IL-18 level was 203.13 ± 90.43 pg/ml. Pearson correlation showed a significant association (p < 0.0001) between IL-18 and PPs and parenchymal abnormality scores. Data suggest a potential role of IL-18 in the pathogenesis of these diseases.

    This prospective study evaluated whether serum glycodelin and insulin-like growth factor binding protein 1 (IGFBP-1) predict the likelihood of embryo implantation in recipients undergoing donor egg in vitro fertilization. We measured glycodelin and IGFBP-1 at 6 points from lining check to lutenizing hormone (LH) + 31. β-Human chorionic gonadotropin levels were first measured at LH + 17. The recipients were divided into those without embryo implantation (group 1, n = 6) and those with successful implantation (group 2, n = 30). Although this is a negative study in that neither glycodelin nor IGFBP-1 alone reflected endometrial (EM) receptivity, the glycodelin/IGFBP-1 ratio on the day of blastocyst transfer was higher in recipients who achieved pregnancy (P = .05). At LH + 17, glycodelin was higher (P = .04), and IGFBP-1 was lower (P = .004) in recipients who achieved pregnancy when compared to those who did not. These observations are likely due to EM changes induced by successful embryo implantation.

    Community-acquired pneumonia (CAP) is amongst the leading causes of death worldwide. As inflammatory markers, cytokines can predict outcomes, if interpreted together with clinical data and scoring systems such as CURB-65, CRB, and Acute Physiology and Chronic Health Evaluation II (APACHE II). The aim of this study was to determine the impact of inflammatory biomarkers on the early mortality of hospitalized CAP patients. Twenty-seven CAP patients needing hospitalization were enrolled for the study and samples of interleukin-1 (IL-1) and interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), C-reactive protein (CRP), and homocystein were collected at the time of admission (day 1) as well as on the seventh day of the treatment. There was a significant reduction in the levels of IL-6 between the first and the second collections. Median IL-6 values decreased from 24 pg/mL (day 1) to 8 pg/mL (day 7) (P=0.016). The median levels of TNF-α were higher in patients: i) with acute kidney injury (AKI) (P=0.045), ii) requiring mechanical ventilation (P=0.040), iii) with short hospital stays (P=0.009), iv) admitted to the intensive care unit (ICU) (P=0.040), v) who died early (P=0.003), and vi) with worse CRB scores (P=0.013). In summary, IL-6 and TNF-α levels were associated with early mortality of CAP patients. Longer admission levels demonstrated greater likelihood of early death and overall mortality, necessity of mechanical ventilation, and AKI.

    The fat-soluble vitamin E comprises the 8 structurally related compounds (congeners) α-, β-, γ-, and δ-tocopherol (with a saturated side chain) and α-, β-, γ-, and δ-tocotrienol (with a 3-fold unsaturated side chain). Little is known regarding the blood and liver concentrations of the 8 vitamin E congeners during the transition from pregnancy to lactation in dairy cows. We thus quantified tocopherols (T) and tocotrienols (T3) in serum and liver and hepatic expression of genes involved in vitamin E metabolism in pluriparous German Holstein cows during late gestation and early lactation and investigated whether dietary supplementation (from d 1 in milk) with conjugated linoleic acids (CLA; 100g/d; each 12% of trans-10,cis-12 and cis-9,trans-11 CLA; n=11) altered these compared with control-fat supplemented cows (CTR; n=10). Blood samples and liver biopsies were collected on d -21, 1, 21, 70, and 105 (liver only) relative to calving. In both groups, the serum concentrations of αT, γT, βT3, and δT3 increased from d -21 to d 21 and remained unchanged between d 21 and 70, but were unaffected by CLA. The concentrations of the different congeners of vitamin E in liver did not differ between the CTR and the CLA groups. In both groups, the concentrations of the vitamin E forms in liver changed during the course of the study. The hepatic mRNA abundance of genes controlling vitamin E status did not differ between groups, but α-tocopherol transfer protein and tocopherol-associated protein mRNA increased with time of lactation in both. In conclusion, the concentrations of vitamin E congeners and the expression of genes related to vitamin E status follow characteristic time-related changes during the transition from late gestation to early lactation but are unaffected by CLA supplementation at the dosage used.

    Aimed to evaluate the postoperative pain and other complications among two cohorts of patients undergone transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) laparoscopic hernia repairs with mechanical fixation, the chart of 305 TAPP and 134 TEP for bilateral not recurrent inguinal hernias were reviewed. The postoperative pain was assessed by using the Verbal Rating Scale (VRS) at one week, one month, 3 months ad six months postoperatively. A subgroup of 60 patients was also administered the QoL EQ-5D questionnaire and follow up for at least 6 months. We found a statistically significant difference in the first day (p = 0.001), in the 7th day (p = 0.002), 30th, and 90th day (p = 0.008) between patients perception of pain in TAPP group and TEP group, but after the 180th day there was not any considerable distinction. On the short term the postoperative pain seems slightly lesser in TEP group.

    Forty-nine cases of primary keratophakia and 13 cases of secondary keratophakia were analyzed for postoperative astigmatism. For primary cases, the surgically induced astigmatism was 1.55 D, whereas for secondary cases it was 0.19 D (insignificant). There was a tendency for both procedures to induce against-the-rule astigmatism, and both procedures were found capable of producing irregular astigmatism.

    Early diagnosis and prevention of Rhodococcus equi pneumonia in foals represent important goals for equine clinicians. Recent protocols for diagnosis and treatment of Rhodococcosis in foals typically rely on a multimodal approach based on sonographic evidence suggestive of pyogranulomas, sonographic abscess scores and laboratory findings including plasma fibrinogen concentrations, blood biochemistry testing and platelet and leukocyte counts. The aim of this study was to assess the utility of weekly testing of serum amyloid A (SAA) and plasma fibrinogen concentrations in foals to achieve early diagnosis of R. equi pneumonia prior to the onset of clinical signs. This testing was used to simulate a clinically practical screening procedure and compared with thoracic ultrasonography performed in parallel. The present study suggests that SAA does not represent a reliable early marker of Rhodococcosis when plasma concentrations are tested weekly. However, when clinical signs of R. equi pneumonia are present, SAA concentrations may allow clinicians to obtain 'real-time' indications concerning both the progress of infection and the effectiveness of therapy. This study raises the possibility that plasma fibrinogen monitoring starting at 1 week of age and repeated on a weekly basis, could serve as a screening test allowing clinicians to identify foals as suspected of R. equi infection. Future investigations regarding both physiological plasma fibrinogen concentrations in foals as well as fibrinogen kinetics in foals affected with R. equi pneumonia, including the establishment of appropriate reference intervals for the test method employed in this study, will be necessary in order to clarify this possibility.

    Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

    Predicting lymph node metastasis (LNM) accurately is of great importance to formulate optimal treatment strategies preoperatively for patients with early gastric cancer (EGC). This study aimed to explore risk factors that predict the presence of LNM in EGC. A total of 697 patients underwent gastrectomy enrolled in this study, were divided into training and validation set, and the relationship between LNM and other clinicopathologic features, preoperative serum combined tumor markers (CEA, CA19-9, CA125) were evaluated. Risk factors for LNM were identified using logistic regression analysis, and a nomogram was created by R program to predict the possibility of LNM in training set, while receiver operating characteristic (ROC) analysis was applied to assess the predictive value of the nomogram model in validation set. Consequently, LNM was significantly associated with tumor size, macroscopic type, differentiation type, ulcerative findings, lymphovascular invasion, depth of invasion and combined tumor marker. In multivariate logistic regression analysis, factors including of tumor size, differentiation type, ulcerative findings, lymphovascular invasion, depth of invasion and combined tumor marker were demonstrated to be independent risk factors for LNM. Moreover, a predictive nomogram with these independent factors for LNM in EGC patients was constructed, and ROC curve demonstrated a good discrimination ability with the AUC of 0.847 (95% CI: 0.789-0.923), which was significantly larger than those produced in previous studies. Therefore, including of these tumor markers which could be convenient and feasible to obtain from the serum preoperatively, the nomogram could effectively predict the incidence of LNM for EGC patients.

    Postoperative care units are run by an anesthesiologist or a surgeon, or a team formed of both. Management of postoperative fluid therapy should be done considering both patients’ status and intraoperative events. Types of the fluids, amount of the fluid given and timing of the administration are the main topics that determine the fluid management strategy. The main goal of fluid resuscitation is to provide adequate tissue perfusion without harming the patient. The endothelial glycocalyx dysfunction and fluid shift to extracellular compartment should be considered wisely. Fluid management must be done based on patient’s body fluid status. Patients who are responsive to fluids can benefit from fluid resuscitation, whereas patients who are not fluid responsive are more likely to suffer complications of over-hydration. Therefore, common use of central venous pressure measurement, which is proved to be inefficient to predict fluid responsiveness, should be avoided. Goal directed strategy is the most rational approach to assess the patient and maintain optimum fluid balance. However, accessible and applicable monitoring tools for determining patient’s actual fluid need should be further studied and universalized. The debate around colloids and crystalloids should also be considered with goal directed therapies. Advantages and disadvantages of each solution must be evaluated with the patient’s specific condition. PMID:26261771

    Background Patients undergoing surgery for gastric cancer may be expected to develop a certain range of postoperative complications. This retrospective cohort study determined if gauging the serum value of total proteins and albumins before and especially after surgery can predict an undesired short term outcome in patients with gastric resections for cancer, as we have not found studies debating the link between low postoperative total proteins or albumins and early postoperative morbidity. Methods A total of 195 patients with gastric cancer who had been subjected to gastric resection (83 patients) or total gastrectomy (111 patients), were subsequently arranged into study group pairs. In each of these group pairs, one group had a complication, while another was without said complication, or total vs. subtotal gastrectomy, etc. Each of these group pairs were compared between them in order to determine if total serum proteins and/or albumins, before and/or after surgery could predict the onset of certain complications or death. In the end, we performed ROC curves to determine the predictability value of variables for certain complications. Results preoperative serum albumin can predict an early onset of anastomotic leakage (p=0.02) as it can predict the occurrence of general complications (p=0.018) and surgical wound infections (p=0.029) as well as a higher risk of reoperation for the management of complications (p=0.028). Total serum protein may be tied to a higher surgical stress, like albumin, as it was significantly lower in patients undergoing total gastrectomy as compared to those subjected to subtotal gastrectomy (p=0.0001 total proteins, p=0.0001 albumins). Postoperative low total serum proteins and albumins translate in a risk of early postoperative death (p=0.031 total proteins, p=0.001 albumins). Conclusion We demonstrated the fact that total serum proteins and serum albumins, checked both before and after surgery, are of great value in helping predict a

    Improving postoperative return of bowel function after abdominal surgery is an important nursing and medical goal. One promising intervention to achieve this goal is to have patients chew gum several times per day in the early postoperative period to stimulate the cephalic-vagal reflex and bowel peristalsis. A study to determine if return of gastrointestinal function after abdominal surgery could be hastened by the simple intervention of chewing gum or sucking on hard candy three times per day is described.

    Statins have beneficial effects on cerebral circulation and brain parenchyma during ischemic stroke and reperfusion. The primary hypothesis of this randomized parallel trial was that treatment with 80 mg/day of atorvastatin administered early at admission after acute atherosclerotic ischemic stroke could reduce serum levels of markers of immune-inflammatory activation of the acute phase and that this immune-inflammatory modulation could have a possible effect on prognosis of ischemic stroke evaluated by some outcome indicators. We enrolled 42 patients with acute ischemic stroke classified as large arteries atherosclerosis stroke (LAAS) randomly assigned in a randomized parallel trial to the following groups: Group A, 22 patients treated with atorvastatin 80 mg (once-daily) from admission day until discharge; Group B, 20 patients not treated with atorvastatin 80 mg until discharge, and after discharge, treatment with atorvastatin has been started. At 72 hours and at 7 days after acute ischemic stroke, subjects of group A showed significantly lower plasma levels of tumor necrosis factor-α, interleukin (IL)-6, vascular cell adhesion molecule-1, whereas no significant difference with regard to plasma levels of IL-10, E-Selectin, and P-Selectin was observed between the 2 groups. At 72 hours and 7 days after admission, stroke patients treated with atorvastatin 80 mg in comparison with stroke subjects not treated with atorvastatin showed a significantly lower mean National Institutes of Health Stroke Scale and modified Rankin scores. Our findings provide the first evidence that atorvastatin acutely administered immediately after an atherosclerotic ischemic stroke exerts a lowering effect on immune-inflammatory activation of the acute phase of stroke and that its early use is associated to a better functional and prognostic profile.

    To compare the efficacy of digital rectal examination and serum prostate specific antigen (PSA) in the early detection of prostate cancer, we conducted a prospective clinical trial at 6 university centers of 6,630 male volunteers 50 years old or older who underwent PSA determination (Hybritech Tandom-E or Tandem-R assays) and digital rectal examination. Quadrant biopsies were performed if the PSA level was greater than 4 μg./l. or digital rectal examination was suspicious, even if transrectal ultrasonography revealed no areas suspicious for cancer. The results showed that 15% of the men had a PSA level of greater than 4 μg./l., 15% had a suspicious digital rectal examination and 26% had suspicious findings on either or both tests. Of 1,167 biopsies performed cancer was detected in 264. PSA detected significantly more tumors (82%, 216 of 264 cancers) than digital rectal examination (55%, 146 of 264, p = 0.001). The cancer detection rate was 3.2% for digital rectal examination, 4.6% for PSA and 5.8% for the 2 methods combined. Positive predictive value was 32% for PSA and 21% for digital rectal examination. Of 160 patients who underwent radical prostatectomy and pathological staging 114 (71%) had organ confined cancer: PSA detected 85 (75%) and digital rectal examination detected 64 (56%, p = 0.003). Use of the 2 methods in combination increased detection of organ confined disease by 78% (50 of 64 cases) over digital rectal examination alone. If the performance of a biopsy would have required suspicious transrectal ultrasonography findings, nearly 40% of the tumors would have been missed. We conclude that the use of PSA in conjunction with digital rectal examination enhances early prostate cancer detection. Prostatic biopsy should be considered if either the PSA level is greater than 4 μg./l. or digital rectal examination is suspicious for cancer, even in the absence of abnormal transrectal ultrasonography findings.

    Colostrum and milk samples from twelve Tunisian camels were analysed for concentration of immunoglobulin G (IgG), alpha-lactalbumin (alpha-la), serum albumin (CSA) and lactoferrin throughout the first 14 milkings post partum (7 days of lactation) using single radial immunodiffusion assay. Concentrations (mg/ml, means+/-SD) at first milking were IgG, 100.7+/-60.4; alpha-la, 2.2+/-0.7; CSA, 8.5+/-3.6 and lactoferrin, 1.2+/-0.3. Large variations were recorded for IgG and CSA concentrations (11.8-211.1 mg/ml and 2.9-13.8 mg/ml respectively) Concentrations of IgG and CSA dropped abruptly in the subsequent milkings while alpha-la concentration increased until milking 5 and then decreased slowly. Lactoferrin dropped only from milking 7. Mean IgG concentrations were 3.6 and 2.5 mg/ml at milking 9 and 13 respectively. However, IgG concentration did not differ significantly, at the 1% level, from milkings 11 to 14. The contribution of CSA to the increase in whey proteins in early milks was greater than that described in the bovine and caprine species.

    Objective The objective of this study was to clarify significant risk factors for postoperative complications in the oral cavity in patients who underwent oral surgery, excluding those with oral cancer. Material and Methods This study reviewed the records of 324 patients who underwent mildly to moderately invasive oral surgery (e.g., impacted tooth extraction, cyst excision, fixation of mandibular and maxillary fractures, osteotomy, resection of a benign tumor, sinus lifting, bone grafting, removal of a sialolith, among others) under general anesthesia or intravenous sedation from 2012 to 2014 at the Department of Oral and Maxillofacial Reconstructive Surgery, Hiroshima University Hospital. Results Univariate analysis showed a statistical relationship between postoperative complications (i.e., surgical site infection, anastomotic leak) and diabetes (p=0.033), preoperative serum albumin level (p=0.009), and operation duration (p=0.0093). Furthermore, preoperative serum albumin level (<4.0 g/dL) and operation time (≥120 minutes) were found to be independent factors affecting postoperative complications in multiple logistic regression analysis results (odds ratio 3.82, p=0.0074; odds ratio 2.83, p=0.0086, respectively). Conclusion Our results indicate that a low level of albumin in serum and prolonged operation duration are important risk factors for postoperative complications occurring in the oral cavity following oral surgery.

    A randomized, double-blind, prospective study was carried out in 100 patients who had undergone some type of surgical treatment in order to evaluate the degree of pain and relief of pain, the degree of achieved analgesia according to the opinion of the observer and consumption of analgesic agents. The evaluation was carried out on seven occasions during the first 12 hours of the postoperative period. Patients received dexamethasone (4 mg before or after the operation or 8 mg after the operation), 6-methylprednisolone (16 mg at the end of the operation) or nothing (control group). Regardless of type, dose or timing of administration of the drugs, all patients receiving corticosteroids presented less pain, more relief of pain (expressed by themselves or in opinion of the observer) and needed lower doses of analgesics during the studied time.

    Postoperative imaging in shoulder instability is still a challenge for radiologists due to various postsurgical anatomical findings that could be considered pathologic in treated shoulder. For this reason is very important a deep knowledge about surgical procedures, anatomical changes after surgery and the appropriate diagnostic imaging modalities to work up the symptomatic postoperative shoulder. Postoperative imaging options include use conventional radiography, magnetic resonance imaging (MRI), MRI arthrography, computed tomography (CT) and CT arthrography. The purpose of our review is to explain the different surgical procedures and to describe postoperative changes detected with radiological imaging.

    Diabetes insipidus (DI) after endoscopic transsphenoidal surgery (ETSS) can lead to increased morbidity, longer hospital stays, and increased medication requirements. Predicting which patients are at high risk for developing DI can help direct services to ensure adequate care and follow-up. The objective of this study was to review our institution's experience with ETSS and determine which clinical/laboratory variables are associated with DI in this patient population. The authors wanted to see if there was an easily determined single value that would help predict which patients develop DI. This represents the largest North American series of this type. We retrospectively reviewed the charts of patients who had undergone ETSS for resection of sellar and parasellar pathology between 2006 and 2011. We examined patient and tumor characteristics and their relationship to postoperative DI. Out of 172 endoscopic transsphenoidal surgeries, there were 15 cases of transient DI (8.7%) and 14 cases of permanent DI (8.1%). Statistically significant predictors of postoperative DI (p < 0.05) included tumor volume and histopathology (Rathke's cleft cyst and craniopharyngioma). Significant indicators of development of DI were postoperative serum sodium, preoperative to postoperative change in sodium level, and urine output prior to administration of 1-deamino-8-D-arginine vasopressin. An increase in serum sodium of ≥2.5 mmol/L is a positive marker of development of DI with 80% specificity, and a postoperative serum sodium of ≥145 mmol/L is a positive indicator with 98% specificity. Identifying perioperative risk factors and objective indicators of DI after ETSS will help physicians care for patients postoperatively. In this large series, we demonstrated that there were multiple perioperative risk factors for the development of DI. These findings, which are consistent with other reports from microscopic surgical series, will help identify patients at risk for diabetes insipidus

    Rationale The current standard surgical treatment for the cervix and uterine cancer is the radical hysterectomy (lymphadenohysterocolpectomy). This has the risk of intraoperative accidents and postoperative associated morbidity. Objective The purpose of this article is the evaluation and quantification of the associated complications in comparison to the postoperative morbidity which resulted after different types of radical hysterectomy. Methods and results Patients were divided according to the type of surgery performed as follows: for cervical cancer – group A- 37 classic radical hysterectomies Class III Piver - Rutledge -Smith ( PRS ), group B -208 modified radical hysterectomies Class II PRS and for uterine cancer- group C -79 extended hysterectomies with pelvic lymphadenectomy from which 17 patients with paraaortic lymphnode biopsy . All patients performed preoperative radiotherapy and 88 of them associated radiosensitization. Discussion Early complications were intra-abdominal bleeding ( 2.7% Class III PRS vs 0.48% Class II PRS), supra-aponeurotic hematoma ( 5.4% III vs 2.4% II) , dynamic ileus (2.7% III vs 0.96% II) and uro - genital fistulas (5.4% III vs 0.96% II).The late complications were the bladder dysfunction (21.6% III vs 16.35% II) , lower limb lymphedema (13.5% III vs 11.5% II), urethral strictures (10.8% III vs 4.8% II) , incisional hernias ( 8.1% III vs 7.2% II), persistent pelvic pain (18.91% III vs 7.7% II), bowel obstruction (5.4% III vs 1.4% II) and deterioration of sexual function (83.3% III vs 53.8% II). PRS class II radical hysterectomy is associated with fewer complications than PRS class III radical hysterectomy , except for the complications of lymphadenectomy . A new method that might reduce these complications is a selective lymphadenectomy represented by sentinel node biopsy . In conclusion PRS class II radical hysterectomy associated with neoadjuvant radiotherapy is a therapeutic option for the incipient stages of cervical cancer

    2015-01-01

    Introduction: In the postoperative phase, the prognosis of multiple trauma patients with severe brain injuries as well as of patients with extensive head and neck surgery mainly depends on protein metabolism and the prevention of septic complications. Wound healing problems can also result in markedly longer stays in the intensive care unit and general wards. As a result, the immunostimulation of patients in the postoperative phase is expected to improve their immunological and overall health. Patients and methods: A study involving 15 patients with extensive ENT tumour surgery and 7 multiple-trauma patients investigated the effect of enteral glutamine supplementation on immune induction, wound healing and length of hospital stay. Half of the patients received a glutamine-supplemented diet. The control group received an isocaloric, isonitrogenous diet. Results: In summary, we found that total lymphocyte counts, the percentage of activated CD4+DR+ T helper lymphocytes, the in-vitro response of lymphocytes to mitogens, as well as IL-2 plasma levels normalised faster in patients who received glutamine-supplemented diets than in patients who received isocaloric, isonitrogenous diets and that these parameters were even above normal by the end of the second postoperative week. Summary: We believe that providing critically ill patients with a demand-oriented immunostimulating diet is fully justified as it reduces septic complications, accelerates wound healing, and shortens the length of ICU (intensive care unit) and general ward stays.

    2013-01-01

    Background Recovery after a major stroke is usually limited, but cell therapy for patients with fixed neurologic deficits is emerging. Several recent clinical trials have investigated mesenchymal stem cell (MSC) therapy for patients with ischemic stroke. We previously reported the results of a controlled trial on the application of autologous MSCs in patients with ischemic stroke with a long-term follow-up of up to 5 years (the 'STem cell Application Researches and Trials In NeuroloGy’ (STARTING) study). The results from this pilot trial are challenging, but also raise important issues. In addition, there have been recent efforts to improve the safety and efficacy of MSC therapy for stroke. Methods and design The clinical and preclinical background and the STARTING-2 study protocol are provided. The trial is a prospective, randomized, open-label, blinded-endpoint (PROBE) clinical trial. Both acute and chronic stroke patients will be selected based on clinical and radiological features and followed for 3 months after MSC treatment. The subjects will be randomized into one of two groups: (A) a MSC group (n = 40) or (B) a control group (n = 20). Autologous MSCs will be intravenously administered after ex vivo culture expansion with autologous ischemic serum obtained as early as possible, to enhance the therapeutic efficacy (ischemic preconditioning). Objective outcome measurements will be performed using multimodal MRI and detailed functional assessments by blinded observers. Discussion This trial is the first to evaluate the efficacy of MSCs in patients with ischemic stroke. The results may provide better evidence for the effectiveness of MSC therapy in patients with ischemic stroke. Trial registration This trial was registered with ClinicalTrials.gov, number NCT01716481. PMID:24083670

    Mounting evidence indicates that serum cholesterol and other risk factors for cardiovascular disease intensify normative trajectories of age-related cognitive decline. However, the neural mechanisms by which this occurs remain largely unknown. To understand the impact of cholesterol on brain networks, we applied graph theory to resting-state fMRI in a large sample of early- to mid-life Veterans (N = 206, Meanage  = 32). A network emerged (centered on the banks of the superior temporal sulcus) that evidenced age-related decoupling (i.e., decreased network connectivity with age), but only in participants with clinically-elevated total cholesterol (≥180 mg/dL). Crucially, decoupling in this network corresponded to greater day-to-day disability and mediated age-related declines in psychomotor speed. Finally, examination of network organization revealed a pattern of age-related dedifferentiation for the banks of the superior temporal sulcus, again present only with higher cholesterol. More specifically, age was related to decreasing within-module communication (indexed by Within-Module Degree Z-Score) and increasing between-module communication (indexed by Participation Coefficient), but only in participants with clinically-elevated cholesterol. Follow-up analyses indicated that all findings were driven by low-density lipoprotein (LDL) levels, rather than high-density lipoprotein (HDL) or triglycerides, which is interesting as LDL levels have been linked to increased risk for cardiovascular disease, whereas HDL levels appear inversely related to such disease. These findings provide novel insight into the deleterious effects of cholesterol on brain health and suggest that cholesterol accelerates the impact of age on neural trajectories by disrupting connectivity in circuits implicated in integrative processes and behavioral control.

Twenty six Duroc x Landrace x Yorkshire piglets at the age of 15 days were used. The piglets had access to creep feed during the suckling. Six piglets were sacrificed for sampling at the beginning of the study. The other 20 piglets were individually housed in metabolic cages and randomly allotted to four corn and soybean meal-based diets including the control group, the antibiotic group with 110 mg lincomycin/kg diet, the COS group containing 0.025% COS, and the GMOS group with 0.20% GMOS, respectively, in a 2-week feeding experiment. Blood urea nitrogen (BUN) level was reduced whereas serum total protein concentration was increased (P<0.05) in responses to the COS and GMOS supplementation. Dietary supplementation of COS and GMOS also increased (P<0.05) the serum GH and IGF-I levels along with enhanced hepatic and the muscle IGF-I mRNA abundance. Dietary supplementation of oligosaccharides such as COS and GMOS may improve growth and feed conversion efficiency by increasing plasma GH and IGF-I levels, in the early-weaned piglets.

    We demonstrated previously that dynamic prognostic markers such as the thyroglobulin (Tg)-doubling time in thyroglobulin antibody (TgAb)-negative papillary thyroid carcinoma (PTC) and changes in pre- and postoperative TgAb levels in TgAb-positive PTC patients more keenly reflect patients' prognosis than conventional static prognostic factors. Here we investigated periodic changes in TgAb levels in 513 TgAb-positive PTC patients who underwent total thyroidectomy. The TgAb levels at 1 year after surgery decreased to <50% of the preoperative values in 407 (79%) patients, and the remaining 106 (21%) patients showed no decrease in TgAb. In 426 patients, TgAb was also measured more than 1 year after surgery. Compared with their TgAb levels 1 year after surgery, 59 patients (14%) showed an increase in TgAb levels of >20% during the follow-up. The postoperative Tg levels at 1 year after surgery remained positive in 44 (9%) patients despite their TgAb positivity. To date (median follow-up period 35 months), 12 of the 426 patients (3%) showed PTC recurrence, and 11 of these patients showed either or both a TgAb elevation later than 1 year after surgery and postoperative Tg positivity. Although further studies with longer follow-ups are necessary, we can conclude that changes in postoperative TgAb levels may be usable as a surrogate tumor marker for TgAb-positive PTC patients after total thyroidectomy.

    We studied the effects of preoperative administration of Hochuekkito (TJ-41) on the host response of patients undergoing gastrectomy or colectomy in a prospective, randomized, multicenter clinical trial. Forty-eight patients were randomized into two groups: one received 7.5 g/day of TJ-41 for 7 days before surgery (n = 22); and the other served as the control group (n = 26). The body temperature and pulse rate in patients in the TJ41 group were significantly better controlled during the study compared with those in the control group. The concentration of serum cortisol on the first postoperative day in the TJ-41 group was also significantly lower compared with that in the control group. These results clearly indicate that the preoperative administration of TJ-41 may ameliorate an excessive postoperative inflammatory response and prolonged immunosuppressed state, resulting in fewer postoperative infectious complications.

    The occurrence of a postoperative pancreatic fistula is one of the most important complications following pancreatic resections. The frequency of this complication varies between 3 % after pancreatic head resection and up to 35 % following distal pancreatectomy. In 2005, the international definition of postoperative pancreatic fistula was standardized according to the approach of the International Study Group of Pancreatic Surgery (ISGPS) including an A-C grading system of the severity. Consequently, results from different studies have become comparable and the historically reported fistula rates can be evaluated more critically. The present review summarises the currently available data on incidence, risk factors, fistula-associated complications and management of postoperative pancreatic fistula.

    Correct interpretation of imaging findings in the postoperative shoulder is impaired by surgical distortion of normal anatomy and possible artifacts. Advanced postoperative imaging of the shoulder in addition to the selection of the best suited modality necessitates familiarity with the surgical procedure that has been performed and its consecutive morphological changes. This article reviews the most common arthroscopic and open techniques used for treatment of shoulder instability, lesions of the superior labral-bicipital complex, primary impingement, and rotator cuff tears, their typical postoperative imaging findings, as well as the diagnostic performance of cross sectional imaging techniques in the detection of recurrent lesions and complications.

    Despite use of meticulous surgical techniques, and regardless of surgical access via laparotomy or laparoscopy, postoperative adhesions develop in the vast majority of women undergoing abdominopelvic surgery. Such adhesions represent not only adhesion reformation at sites of adhesiolysis, but also de novo adhesion formation at sites of surgical procedures. Application of antiadhesion adjuvants compliment the benefits of meticulous surgical techniques, providing an opportunity to further reduce postoperative adhesion development. Improved understanding of the pathophysiology of adhesion development and distinguishing variations in the molecular biologic mechanisms from adhesion-free peritoneal repair represent future opportunities to improve the reduction of postoperative adhesions. Optimization of the reduction of postoperative adhesions will likely require identification of unique, personalized approaches in each individual, representing interindividual variation in peritoneal repair processes.

    Introduction: Several studies have found anesthetic agents including propofol in ovarian follicular fluid. However, little is known about the effect of anesthetic agents on ovarian function. We aimed to investigate whether there were differences in the postoperative levels of sex hormones when propofol was used as the anesthetic agent. Methods: A retrospective review was done of 80 patients who underwent ovarian surgery, with 72 infertile women serving as controls. Patients were included in the study if their serum estradiol (E2) and follicle stimulating hormone (FSH) levels were measured during their first postoperative menstrual cycle. Results: Patients were grouped according to the use or non-use of propofol as follows: propofol group (n = 39) and non-propofol group (n = 41). The control group did not undergo surgery. Postoperative E2 levels did not differ between the three groups, but FSH levels were significantly higher in the patients who had undergone surgery compared to controls (p < 0.05). Post-hoc analysis of E2 and FSH levels in the propofol and non-propofol groups did not show any significant differences. Conclusions: The use of propofol did not result in any differences compared to other anesthetic agents in terms of postoperative sex hormone levels after gynecologic surgery. The type of anesthetic agent does not seem to affect the postoperative levels of female sex hormones. PMID:27134297

  1. Perioperative changes in serum CA125 levels: a prognostic factor for disease-specific survival in patients with ovarian cancer

    Objective In patients with advanced stage epithelial ovarian cancer (EOC) the volume of residual tumor after debulking is known as prognostic factor for survival. We wanted to examine the relationship between postoperative decline in serum CA125 and residual disease after cytoreductive surgery and evaluate perioperative changes in serum CA125 levels as predictor for disease-specific survival. Methods A retrospective study was conducted of patients with FIGO stage IIb-IV EOC treated with cytoreductive surgery, followed by chemotherapy between 1996 and 2010 in three hospitals in the Southeastern region of the Netherlands. Data were analyzed with the use of multilevel linear regression and Cox-proportional hazard regression models. Results A postoperative decline in serum CA125 level of ≥80% was associated with complete primary cytoreduction (p=0.035). Univariate analyses showed favorable associations with survival for both the degree of decline in serum CA125 and residual tumor after primary cytoreduction. In multivariate analyses the decline in serum CA125 but not the outcome of surgery remained significantly associated with better survival (HR50%–79%=0.52 [95% CI: 0.28–0.96] and HR≥80%=0.26 [95% CI: 0.13–0.54] vs. the serum CA125 decline of <50% [p<0.001]). Conclusion The current study, although hampered by possible biases, suggests that the perioperative decline in serum CA125 is an early biomarker that predicts disease-specific survival in patients who underwent primary cytoreductive surgery for advanced stage EOC. If confirmed prospectively, the perioperative change in serum CA125 could be a better marker for residual tumor volume after primary cytoreductive surgery (and therewith disease-specific survival) than the surgeons’ estimation of residual tumor volume.

    Postoperative ileus is a natural part of recovery following abdominal and intestinal surgery. Research in the laboratory and clinical arenas has challenged the long-held belief that enteral nutrition (EN) should not be administered until bowel function has resumed, which is typically judged by a subjective bowel function assessment. Traditional postoperative management begins with clinical monitoring of return of bowel function, followed by a clear liquid diet that is advanced to regular solid food as tolerated. Studies have consistently demonstrated that early EN is safe and well tolerated, showing a reduction in wound morbidity and healing, fewer septic complications, diminished weight loss, and improved protein kinetics in patients administered early EN. Barriers to early enteral feeding include fear of GI morbidity, anastomotic disruption or leak but have not been proven valid in clinical or experimental trials. A clear liquid diet is the most frequently ordered first postoperative meal regardless of early or delayed administration. Although generally well tolerated, this diet fails to provide adequate nutrients to the postsurgical patient. In contrast, advancement to a regular diet as the initial meal has been shown to be well tolerated and provides significantly more nutrients than a clear liquid diet. This article reviews basic GI physiology, including motility, nutrient absorption, and the changes that occur in regulation and function of the GI tract following surgery, as well as clinical data regarding postoperative GI function and diet advancement. This will be applied to the clinical practices of postoperative dietary advancement to discuss the timing and choice of initial feeding in the postoperative patient.

    Background The reduction of insulin-like growth factor 1 (IGF-1) plasma levels is associated with the degree of liver dysfunction and mortality in cirrhotic patients. However, little research is available on the recovery of the IGF-1 level and its prognostic role after liver transplantation (LT). Methods From April 2010 to May 2011, 31 patients were prospectively enrolled (25/6 M/F; mean age±SEM: 55.2±1.4 years), and IGF-1 serum levels were assessed preoperatively and at 15, 30, 90, 180 and 365 days after transplantation. The influence of the donor and recipient characteristics (age, use of extended criteria donor grafts, D-MELD and incidence of early allograft dysfunction) on hormonal concentration was analyzed. The prognostic role of IGF-1 level on patient survival and its correlation with routine liver function tests were also investigated. Results All patients showed low preoperative IGF-1 levels (mean±SEM: 29.5±2.1), and on postoperative day 15, a significant increase in the IGF-1 plasma level was observed (102.7±11.7 ng/ml; p<0.0001). During the first year after LT, the IGF-1 concentration remained significantly lower in recipients transplanted with older donors (>65 years) or extended criteria donor grafts. An inverse correlation between IGF-1 and bilirubin serum levels at day 15 (r = -0.3924, p = 0.0320) and 30 (r = -0.3894, p = 0.0368) was found. After multivariate analysis, early (within 15 days) IGF-1 normalization [Exp(b) = 3.913; p = 0.0484] was the only prognostic factor associated with an increased 3-year survival rate. Conclusion IGF-1 postoperative levels are correlated with the graft’s quality and reflect liver function. Early IGF-1 recovery is associated with a higher 3-year survival rate after LT.

    Amyloid β (Aβ) deposition has been implicated in the pathogenesis of Alzheimer's disease. However, the early effect of Aβ deposition on metabolism remains unclear. In the present study, thus, we explored the metabolic changes in the hippocampus and serum during first 2 weeks of Aβ25-35 injection in rats by using an integrated method of NMR-based metabolomics and ANOVA-simultaneous component analysis (ASCA). Our results show that Aβ25-35 injection, time, and their interaction had statistically significant effects on the hippocampus and serum metabolome. Furthermore, we identified key metabolites that mainly contributed to these effects. After Aβ25-35 injection from 1 to 2 weeks, the levels of lactate, N-acetylaspartate, creatine, and taurine were decreased in rat hippocampus, while an increase in lactate and decreases in LDL/VLDL and glucose were observed in rat serum. Therefore, we suggest that the reduction in energy and lipid metabolism as well as an increase in anaerobic glycolysis may occur at the early stage of Aβ25-35 deposition.

    Background Protein losing enteropathy (PLE) is a challenging complication after Fontan operation. Subclinical enteric protein loss may precede development of overt PLE. We evaluated the acute effects of Fontan circulation on enteric protein loss and mesenteric vascular resistance. Methods A prospective cohort study was performed evaluating enteric protein loss in children undergoing Fontan operation. Stool alpha-1-antitrypsin (A1AT) concentration was measured in the pre-operative, early post-operative, and intermediate post-operative (3–9 months) periods. The intestinal circulation was characterized by Doppler-derived resistance indices of the superior mesenteric artery, and serum albumin and protein levels were obtained. Results We enrolled 33 subjects at a median age at operation of 3.0 (2.5–3.3) years. No clinical PLE was observed. Six of the 93 stool A1AT samples obtained were elevated (>54 mg/dl), with two abnormal samples at each of the three time points. Two of the five subjects with elevated stool A1AT values had significant hemodynamic disturbances requiring intervention (junctional bradycardia or tricuspid stenosis). There was no difference in superior mesenteric artery resistance in the pre-operative versus early post-operative period (p=0.9). Serum albumin levels were lower in the early post-operative period compared to the pre-operative period (3.2 mg/dl [IQR 2.9–3.5] vs. 4.1 mg/dl [IQR 3.4–4.5], p=0.01) but did not correlate with abnormal stool A1AT concentration or superior mesenteric artery resistance indices. Conclusions The Fontan operation does not commonly result in acute development of increased enteric protein loss. However, increased enteric protein loss may occur in children before or after Fontan operation, particularly when hemodynamic disturbances are present. PMID:26652137

    Hypothyroidism and hyperthyroidism are commonly present conditions in adults, leading to neurological symptoms, affecting the central and peripheral nervous system, and to neurocognitive impairment. Several studies investigated a possible association between Alzheimer's disease (AD) and thyroid dysfunctions. Increasing evidence supports an extensive interrelationship between thyroid hormones and the cholinergic system, which is selectively and early affected in AD. Moreover, thyroid hormones negatively regulate expression of the amyloid-beta protein precursor (AbetaPP), which plays a key role in the development of AD. A condition, the so called euthyroid sick syndrome (ESS), characterized by reduced serum T_{3} and T_{4} concentrations without increased serum thyroid stimulation hormone secretion, occurs within hours after major surgery. After surgery, elderly patients often exhibit a transient, reversible state of cognitive alterations. Delirium occurs in 10-26% of general medical patients over 65, and it is associated with a significant increase in morbidity and mortality. Modifications in thyroid hormone functioning may take place as a consequence of psycho-physical stress caused by surgery, and probably as a consequence of reduced conversion of T4 into T3 by the liver engaged in metabolizing anesthetic drugs. Therefore, modifications of thyroid hormones post-surgery, might play a role in the pathogenesis of postoperative cognitive dysfunction.

    The effects of early postoperative nasoduodenal feeding on nutrition and metabolic response were studied using 24 patients after biliary surgery. The patients were randomly divided into two groups with 12 in each group. Group I was fed via a nasoduodenal tube from the first postoperative day but control group II was not fed until the fourth postoperative day. The hospital blenderized tube feeding diet provided the enteric nutrition (17% protein, 33% fat and 50% carbohydrate). The nutritional status of the 2 groups was compared over a one week period. The changes in nitrogen balance were measured daily for 8 days. The group fed early had a significantly reduced negative nitrogen balance when compared to the group whose feeding was started later. (-1.91 +/- 1.05 g/day vs -5.84 +/- 0.48 g/day). There was no difference in serum albumin and transferrin levels, but serum prealbumin levels in the group fed early were more desirable than those of the control group (from 15.8 +/- 2.5 mg/dl to 28.9 +/- 3.8 mg/dl vs from 18.0 +/- 2.0 mg/dl to 25.9 +/- 3.9 mg/dl). Total lymphocyte count was also better in the group fed early than in the controls (from 1,325 +/- 204 cells/mm3 to 2,655 +/- 584 cells/mm3 vs from 1,277 +/- 188 cells/mm3 to 1,877 +/- 440 cells/mm3). All the patients in group I felt better than those in group II during the study course. These results indicated that those patients provided with early nasoduodenal feeding after a biliary operation displayed a better nitrogen balance, and a faster increase in short half life visceral protein and total lymphocyte count.

  9. Post-operative urinary retention.

    PubMed

    Steggall, Martin; Treacy, Colm; Jones, Mark

    Urinary retention is a common complication of surgery and anaesthesia. The risk of post-operative urinary retention is increased following certain surgical procedures and anaesthetic modalities, and with patients' advancing age. Patients at increased risk of post-operative urinary retention should be identified before surgery or the condition should be identified and treated in a timely manner following surgery. If conservative measures do not help the patient to pass urine, the bladder will need to be drained using either an intermittent catheter or an indwelling urethral catheter, which can result in catheter-associated urinary tract infections. This article provides an overview of normal bladder function, risk factors for developing post-operative urinary retention, and treatment options. Guidance drawn from the literature aims to assist nurses in identifying at-risk patients and inform patient care.

    The aim of this study was to establish the serum concentrations, ranges, and trends of Th1 type cytokine (tumor necrosis factor (TNF)-α and interleukin (IL)-2), Th2 type cytokine (IL-10), and nitric oxide (NO) during the estrous cycle, early pregnancy and abortion in goats. Boer goats (n=25) having symptoms of normal estrous cycles were selected, 20 were mated and 15 conceived a pregnancy, and the remaining five were not mated and served as estrous controls. On the Day 60 of pregnancy, all 15 pregnant goats were induced to abort the pregnancy by intramuscular injection of prostaglandin (PG). Serum samples were collected on Days 1, 7, 14, and 19 of the estrous cycle, at Days 0, 10, 20, 30, 40, 50, and 60 of pregnancy, and at Days 1, 3, 8, 10 over the period when abortion were occurring. Results of the present study indicated that during the estrous cycle the balance between Th1 and Th2 cytokines slightly shifted toward Th1 cytokine production (TNF-α and IL-2). The NO may have a direct positive role in inducing a Th1 response. During early pregnancy, TNF-α and IL-2 serum concentrations markedly increased from Days 0 to 10, and gradually decreased from Days 10 to 60, while IL-10 and NO serum concentrations remained elevated from Days 0 to 60. The increased concentrations of IL-10 and decreased concentrations of TNF-α and IL-2 are characteristic of a Th2-enhanced response, which may be related to increased concentrations of NO. These changes may be essential to maintain a normal pregnancy. In addition, the serum concentrations of TNF-α, IL-2 and NO at Days 1, 3, 8 and 10 of the period of induced abortion were markedly greater than that on Day 60 of pregnancy. Conversely, IL-10 concentrations at these four time points of abortion were markedly less than that on Day 60 of pregnancy. After abortion, the Th2 response shifted to a Th1-enhanced response. Thus, NO concentrations increase and the Th1-enhanced response may function synergistically to be involved in

    According to the current opinion, lymph-heart striated muscle represents a specialized type of skeletal muscles in frogs. Here, we studied muscle fibers in mechanically damaged lymph hearts during the first postoperative week using electron-microscopic autoradiography. We present evidence that both, the satellite cells and pre-existing muscle fibers bordering the site of injury, contribute directly to the lymph-heart muscle regeneration. Several muscle fibers located in the vicinity of the damaged area displayed features of nuclear and sarcoplasmic activation. We also observed ultrastructural changes indicating activation of a few satellite cells, namely decondensation of chromatin, enlargement of nuclei and nucleoli, appearance of free ribosomes and rough endoplasmic reticulum tubules in the cytoplasm. Electron-microscopic autoradiography showed that 4 h after single (3)H-thymidine administration on the seventh day after injury not only the activated satellite cells, but also some nuclei of myofibers bordering the injured zone are labeled. We showed that both, the myonuclei of fibers displaying the signs of degenerative/reparative processes in the sarcoplasm and the myonuclei of the fibers enriched with highly organized myofibrils, can re-enter into the S-phase. Our results indicate that the nuclei of lymph-heart myofibers can reactivate DNA synthesis during regenerative myogenesis, unlike the situation in regenerating frog skeletal muscle where myogenic cells do not synthesize DNA at the onset of myofibrillogenesis.

    A significant percentage of the patients admitted to our hospitals show signs of malnutrition that are neither detected nor treated and often become more severe during the hospital stay. This malnutrition can contribute to the loss of some important functions as, for instance the capacity for immune response and healing. In this study we use several simple, economical parameters to evaluate the nutritional status upon admittance and upon leaving the hospital of all the patients who in the course of a year occupied four randomly chosen beds in a general surgery ward at a county hospital in the Valencian Community. The results show that hospitalization reduced the number of over weight patients, duplicated the number of hypoalbuminemics and triplicated the number of people with body weight and body mass index (BMI) below normal levels. In patients over 40 hospitalization decrease the values of all the parameters studied, whereas in younger subjects only the weight, the BMI and serum albumin values were affected. Fifty seven percent of the patients suffer some kind of postoperative complication and this incidence is higher among patients with malnutrition upon admittance. The most common complication is the nosocomial pneumonia and urine infection. The nutritional parameters that best predict possible postoperative complications are low values of serum albumin, total lymphocyte count, tricipital fat skin fold and arm circumference. In general, postoperative complications show only a slight positive correlation with the length of the hospital stay, but the longer the stay is the worst the nutritional status becomes.

    Rheumatoid arthritis is often accompanied by massive destruction of the smaller and larger joints even with early therapy using antirheumatic drugs. In these cases total joint arthroplasty is the only surgical option, especially for the knee and hip joint. Knowledge of the specific disease-related postoperative characteristics is a prerequisite for the successful treatment of patients with rheumatoid arthritis. As dislocation of the arthroplastic joint does not occur more often in rheumatoid arthritis, the risk of periprosthetic infection is increased due to the use of biologicals. Therefore, a perioperative optimization is obligatory. In order to facilitate independence in daily living physiotherapy in combination with aids such as arthritis crutches, gripping pliers or raised toilet seat need to be started as soon as possible after surgical treatment. To achieve this goal it is recommended to refer patients with inflammatory arthritis to inpatient rehabilitation facilities. With respect to the specific postoperative treatment after joint replacement the long-term results are comparable with those from patients with primary osteoarthritis.

    A sufficient analgesic treatment in the early postoperative period is important for the patients comfort level. Moreover, physical therapy for prophylaxis of pneumonia and thrombosis is better tolerated. In a prospective study, we compared two postoperative pain management regimens to establish a sufficient pain management without the need of additional costs or manpower. Of 215 patients undergoing major urologic surgery, 111 patients received on demand medication exclusively (group 1), whereas 104 patients were treated with basic analgesics combined with on demand medication (group 2). Pain intensity, side effects and subjective well being were evaluated with a visual analogue scale and a standardised interview. Pain intensity and side effects were significantly lower in group 2. Thus, with combined analgesic treatment, postoperative pain relieve can be achieved safely and without additional costs.

    Diagnosis of renal cell carcinoma (RCC) at an early stage is challenging, but it provides the best chance for cure. We aimed to develop a predictive diagnostic method for early-stage RCC based on a biomarker cluster using nuclear magnetic resonance (NMR)-based serum metabolomics and self-organizing maps (SOMs). We trained and validated the SOM model using serum metabolome data from 104 participants, including healthy individuals and early-stage RCC patients. To assess the predictive capability of the model, we analyzed an independent cohort of 22 subjects. We then used our method to evaluate changes in the metabolic patterns of 23 RCC patients before and after nephrectomy. A biomarker cluster of 7 metabolites (alanine, creatine, choline, isoleucine, lactate, leucine, and valine) was identified for the early diagnosis of RCC. The trained SOM model using a biomarker cluster was able to classify 22 test subjects into the appropriate categories. Following nephrectomy, all RCC patients were classified as healthy, which was indicative of metabolic recovery. But using a diagnostic criterion of 0.80, only 3 of the 23 subjects could not be confidently assessed as metabolically recovered after nephrectomy. We successfully followed-up 17 RCC patients for 8 years post-nephrectomy. Eleven of these patients who diagnosed as metabolic recovery remained healthy after 8 years. Our data suggest that a SOM model using a biomarker cluster from serum metabolome can accurately predict early RCC diagnosis and can be used to evaluate postoperative metabolic recovery.

    Background Today, early diagnosis of upper gastrointestinal (GI) tract malignancies and their surgical resection is becoming more feasible. One of the important side effects in upper GI tract malignancies is malnutrition which has direct relationship with postoperative complications. Nonetheless, there is no easy regimen of nutrition for these patients especially for the first week after operation. Accordingly we present a simple method for improving feeding such patients via tube jejunostomy. The aim of this study was to investigate the impact of early enteral feeding (EEF) on postoperative course after complete resection of upper gastrointestinal tract malignancy and reconstruction. Methods Between September 2005 to September 2008, 60 consecutive patients (22 female, 38 male) with upper GI tract malignancies who had undergone complete resection and reconstruction enrolled in this study. The patients randomly divided equally in two groups of control and EEF. Control group was treated with traditional management of nil by mouth and intravenous fluids for the first five postoperative days and then with liquids and enteral regular diet when tolerated. In EEF group the patients were fed by tube jejunostomy from 1st postoperative day and assessed for nutritional status before surgery and 5 days after surgery. Both groups were monitored on the basis of weight gain, clinical and paraclinical parameters and postoperative complications. Results Sixty patients were randomly divided to two equal groups. Surgical procedures were similar in two groups and no significant difference in demographic and basic nutritional status were found. On 5th postoperative day serum albumin was 4.2±0.4 g/dl in EEF and 3.6±0.3 g/dl in control group (p= 0.041). Also serum transferrin was 260.8±2.5 mg/dl and 208±1.8 mg/dl in EEF and control group respectively (p < 0.001). Moreover, hospital stay was shorter in EEF group (7.7±3.1 vs. 14±2.5 days, p = 0.009).There were four (13

    Ninety-eight patients admitted to the emergency rooms of three urban hospitals with a diagnosis of either ischemic stroke or hemorrhagic stroke exhibited early and significant deficits in serum ionized Mg2+ (IMg2+), but not total Mg, as measured with a unique Mg2+-sensitive ion-selective electrode. Twenty-five percent of these stroke patients exhibited >65% reductions in the mean serum IMg2+ found in normal healthy human volunteers or patients admitted for minor bruises, cuts or deep lacerations. The stroke patients also demonstrated significant elevation in the serum ionized Ca2+ (ICa2+)/IMg2+ ratio, a sign of increased vascular tone and cerebrovasospasm. Exposure of primary cultured canine cerebral vascular smooth muscle cells to the low concentrations of IMg2+ found in the stroke patients, e.g. 0.30-0.48 mM, resulted in rapid and marked elevations in cytosolic free calcium ions ([Ca2+]i) as measured with the fluorescent probe, fura-2, and digital image analysis. Coincident with the rise in [Ca2+]i, many of the cerebral vascular cells went into spasm. Reintroduction of normal extracellular Mg2+ ion concentrations failed to either lower the [Ca2+]i overload or reverse the rounding-up of the cerebral vascular cells. These results suggest that changes in Mg2+ metabolism play important roles in stroke syndromes and in the etiology of cerebrovasospasm associated with cerebral hemorrhage.

    MR imaging has been widely evaluated in the assessment of patients with recurrent or residual symptoms following meniscal surgery. Importantly, the causes of such symptoms may relate to failure or complication of the surgical procedure, a possible recurrent or residual meniscal tear, or may be related to other causes of joint symptoms, including tears of the contralateral meniscus, or local hyaline cartilage, or marrow abnormalities subjacent to or distant to the meniscal surgical site. The complex diagnostic issues involved in the MR imaging evaluation of the postoperative meniscus were identified in early MR imaging studies. The knowledge of the normal MR imaging appearance of the knee after the more common repair procedures will allow radiologists to recognize complications associated with such procedures. In this article, we discuss the MR imaging evaluation of the knee after meniscal surgery.

    Purpose To evaluate postoperative pain and early recovery in cataract patients. Patients and methods A total of 201 patients who underwent elective first eye cataract extraction surgery were enrolled, and 196 were included in the final analysis. The study design was a single-center, prospective, follow-up study in a tertiary hospital in eastern Finland. Postoperative pain was evaluated with the Brief Pain Inventory at four time points: at baseline, and at 24 hours, 1 week, and 6 weeks postsurgery. Results Postoperative pain was relatively common during the first hours after surgery, as it was reported by 67 (34%) patients. After hospital discharge, the prevalence decreased; at 24 hours, 1 week, and 6 weeks, 18 (10%), 15 (9%) and 12 (7%) patients reported having ocular pain, respectively. Most patients with eye pain reported significant pain, with a score of ≥4 on a pain scale of 0–10, but few had taken analgesics for eye pain. Those who had used analgesics rated the analgesic efficacy of paracetamol and ibuprofen as good or excellent. Other ocular irritation symptoms were common after surgery; as a new postoperative symptom, foreign-body sensation was reported by 40 patients (22%), light sensitivity by 29 (16%), burning by 15 (8%), and itching by 15 (8%). Conclusion Moderate or severe postoperative pain was relatively common after cataract surgery. Thus, all patients undergoing cataract surgery should be provided appropriate counseling on pain and pain management after surgery. PMID:23885165

    The postoperative electromyographic profile of the proximal jejunum and its evolution during recovery from surgery were defined in fasted humans after cholecystectomy. An intraluminal probe supporting four groups of bipolar electrodes was transnasally inserted at the end of surgery to allow continuous recording of jejunal electrical activity over 4 consecutive days. Electromyographic activity was characterized by an early reappearance of phase 3 of migrating myoelectric complexes (MMC) lasting 5.2 +/- 0.6 minutes and occurring at 38.1 +/- 3.1-minute intervals at day 1 after surgery. During the 4 days after surgery, there was an increased duration of MMC, mainly consisting of phase 2 occurrence with an increased duration and lengthening of the MMC cycle. The amplitude of spikes during phase 3 increased. During the postoperative period, characterized by an inversion of the circadian rhythm, the velocity of propagation was higher (p less than 0.05) between 18:00 and 06:00 (4.0 +/- 0.5 cm/minute) than between 06:00 and 18:00 (3.1 +/- 0.3 cm/minute). In contrast, the duration of phase 2 was lower during nighttime (18:00 to 06:00) than during daytime. The authors conclude that during the early (1 to 2 days) period after cholecystectomy, the jejunal electromyographic activity is limited to phase 3 activity, but that a normal fasted pattern is recovered after 4 days. A progressive reorganization and coordination of the intestinal tract may account for this delay. PMID:1543395

    Objective After 9/11/2001, some Fire Department of New York (FDNY) workers had excessive lung function decline. We hypothesized that early serum matrix metalloproteinases (MMP) expression predicts World Trade Center-Lung Injury (WTC-LI) years later. Methods This is a nested case-control analysis of never-smoking male firefighters with normal pre-exposure Forced Expiratory Volume in one second (FEV1) who had serum drawn up to 155 days post 9/11/2001. Serum MMP-1, 2,3,7,8, 9, 12 and 13 were measured. Cases of WTC-LI (N = 70) were defined as having an FEV1 one standard deviation below the mean (FEV1≤77%) at subspecialty pulmonary evaluation (SPE) which was performed 32 months (IQR 21–53) post-9/11. Controls (N = 123) were randomly selected. We modeled MMP's ability as a predictor of cases status with logistic regression adjusted for time to blood draw, exposure intensity, weight gain and pre-9/11 FEV1. Results Each log-increase in MMP-3 and MMP-12 showed reduced odds of developing WTC-LI by 73% and 54% respectively. MMP-3 and MMP-12 consistently clustered together in cases, controls, and the cohort. Increasing time to blood draw significantly and independently increased the risk of WTC-LI. Conclusions Elevated serum levels of MMP-3 and MMP-12 reduce the risk of developing WTC-LI. At any level of MMP-3 or 12, increased time to blood draw is associated with a diminished protective effect. PMID:24146820

    Singultus, or hiccups, is a common medical condition. Despite exponential leaps in medicine, the pathophysiologic cause remains poorly defined. Persistent singultus has been associated with conditions such as pulmonary embolism and myocardial infarction. Singultus is also a well-known postoperative complication. The criterion standard of care for patients with singultus involves ruling out lethal pathologic causes, attempting physical stimulation with Valsava maneuvers or drinking water, and, if no relief has been achieved, administering drugs to ease the symptoms. The authors report a case of a man whose postoperative singultus was successfully managed with osteopathic manipulative treatment. This approach addresses many of the possible underlying neuromechanical causes of the aberrant reflex with minimal potential for adverse effects. Physicians should consider osteopathic manipulative treatment in the care of patients with singultus.

    Postoperative pain after septorhinoplasty and its optimal management has not been described in detail. Fifty-two adult septorhinoplasty patients were included in a prospective cohort single center study. Patients' and surgical characteristics were evaluated. Outcome and process parameters were analyzed using the questionnaires of the German-wide project Quality Improvement in Postoperative Pain Management (QUIPS) on the first postoperative day. Pain during the first operative day after septorhinoplasty was moderate. Pain management predominately consisted of remifentanil intraoperatively, metamizole in the recovery room, in combination with piritramide in one-third of the patients, and metamizole on ward. Patients younger than 31 years were less satisfied with pain management (P = 0.018). Open rhinoplasty was associated with less satisfaction with pain management (P = 0.007). Use of rib grafts led to more mobility, breathing, sleeping and mood disturbances (P = 0.003, 0.047; 0.047; 0.022, respectively). Preoperative pain counseling was followed by higher satisfaction, less breathing and mood disturbances after surgery (P = 0.021; 0.004; 0.046, respectively). Opioids in the recovery room in addition to non-opioids and treatment with non-opioids on ward led to less maximal pain (P = 0.027 and 0.040, respectively). We conclude that QUIPS is an easy tool to evaluate the quality of postoperative pain management following rhinoplasty. Preoperative pain counseling, specific care for patients with rib grafts, consequent use of opioids in the recovery room in addition to non-opioids, and use of non-opioids on ward seem to be effective to improve pain management after septorhinoplasty.

    Postoperative alopecia is a rare occurrence seen after a variety of surgical procedures performed under general anesthesia. The speculated cause is pressure-induced ischemia due to prolonged head immobilization. This case describes a patient who developed this complication after undergoing sacrocolpopexy. A 57-year-old postmenopausal Caucasian female was consented to undergo a robotic-assisted sacrocolpopexy, perineoplasty, and midurethral sling with possible conversion to an open procedure. The indication was symptomatic proximal and distal rectocele with foreshortened vagina. It was converted to laparotomy due to difficult presacral dissection. Her total operative time was 540 with 240 min in the Trendelenburg position. No intraoperative hypotension or excessive blood loss was noted. She started complaining of scalp pain in the postoperative recovery area. She developed soreness, crusting, and later alopecia in the same area. It was noted at her 3-week office visit. Referral was made for dermatology and anesthesiology evaluation. There was spontaneous full recovery by the 5th month. Postoperative alopecia is a rare condition mimicking alopecia areata but it is preceded by inciting events. There is some evidence to suggest that it is a preventable condition by frequent head repositioning during surgery. This case report is intended to increase the surgeon's awareness about this rare complication as its occurrence can be distressing for the patient.

    Conservative treatment of metastatic germ-cell tumor of the ovary does not exclude the possibility of pregnancy in the future. Serum beta-human chorionic gonadotropin (beta-hCG) serves as pregnancy test, and has also been proven to be a useful marker for ovarian germ-cell tumors. This paper is a case report of a 19-year-old patient who was admitted to a district hospital in emergency due to pelvic pain, amenorrhoea, and free fluid in the pelvis. Laboratory tests demonstrated slight increase in beta-hCG serum concentration and transvaginal ultrasound (TVUS) showed no evidence of gestational sac in the uterus. At the age of 14, the patient was diagnosed with malignant germ-cell tumor of the left ovary in FIGO Stage IV and was treated with four courses of chemotherapy according to TGM-95 protocol with etoposide, ifosfamide, and cisplatin, followed by conservative surgery and adjuvant two courses of cytostatics. The initial diagnosis was recurrence of ovarian malignancy and the patient was referred to an oncology center. Wait-and-see approach and repeated ultrasound examination confirmed a normal intrauterine pregnancy which concluded with the delivery of a healthy newborn through cesarean section.

    Neurological signs and serum acetylcholine receptor antibody (AChR-Ab) levels before and after thymectomy were monitored in a 6-year-old male cat with acquired Myasthenia Gravis (MG) as a paraneoplastic syndrome of thymoma. Soon after surgery, the neurological symptoms relapsed, and the cholinesterase inhibitor was administered to control them. The AChR-Ab levels increased postoperatively until 90 days after surgery. This is the first report on long term measurements of serum AChR-Ab levels in a cat with MG. Although thymectomy is valuable for the removal of thymoma, it may not resolve MG symptoms, neurological signs and serum AChR-Ab levels, without medication early after surgery. Also, this case report indicates that the AChR-Ab level might be a guide to detect a deterioration of MG symptoms. PMID:27593682

    Mycobacterium avium subspecies paratuberculosis (MAP) is the aetiological agent of Johne’s disease (JD), a chronic enteritis in ruminants that causes substantial economic loses to agriculture worldwide. Current diagnostic assays are hampered by low sensitivity and specificity that seriously complicate disease control; a new generation of diagnostic and prognostic assays are therefore urgently needed. Circulating microRNAs (miRNAs) have been shown to have significant potential as novel biomarkers for a range of human diseases, but their potential application in the veterinary sphere has been less well characterised. The aim of this study was therefore to apply RNA-sequencing approaches to serum from an experimental JD infection model as a route to identify novel diagnostic and prognostic miRNA biomarkers. Sera from experimental MAP-challenged calves (n = 6) and age-matched controls (n = 6) were used. We identified a subset of known miRNAs from bovine serum across all samples, with approximately 90 being at potentially functional abundance levels. The majority of known bovine miRNAs displayed multiple isomiRs that differed from the canonical sequences. Thirty novel miRNAs were identified after filtering and were found within sera from all animals tested. No significant differential miRNA expression was detected when comparing sera from MAP-challenged animals to their age-matched controls at six-month’s post-infection. However, comparing sera from pre-infection bleeds to six-month’s post-infection across all 12 animals did identify increased miR-205 (2-fold) and decreased miR-432 (2-fold) within both challenged and control groups, which suggests changes in circulating miRNA profiles due to ageing or development (P<0.00001). In conclusion our study has identified a range of novel miRNA in bovine serum, and shown the utility of small RNA sequencing approaches to explore the potential of miRNA as novel biomarkers for infectious disease in cattle.

    During our initial experience with endoscopic third ventriculostomies, we observed intraoperative bradycardia and postoperative hyperkalemia. The present study was carried out to verify the consistency of these initial observations. Intraoperative heart rate (HR) changes and postoperative serum K + changes were studied prospectively in 20 patients of endoscopic third ventriculostomy. Another 6 patients who underwent endoscopic procedures other than ventriculostomy acted as controls. The anaesthetic technique and intraoperative and postoperative fluid regimen were similar in all patients. Serum K + concentrations were measured intraoperatively and once a day for the next 5 days. The third ventriculostomy group exhibited a significant slowing of the heart rate during the fenestration of the floor of the third ventricle (112 +/- 26 to 101 +/- 28 bpm, p < 0.001) and also at the time of the reversal of the neuromuscular block at the end of surgery (104 +/- 29 to 96 +/- 33 bpm, p < 0.01). The control group did not exhibit similar changes in the heart rate. The postoperative increase in serum K + values in the ventriculostomy group (0.82 +/- 0.55 mmol/L) was higher than that in the control group (0.10 +/- 0.44 mmol/L) (p < 0.01). Endoscopic third ventriculostomy is associated with a significant bradycardia at the time of fenestration and at the time of reversal of the neuromuscular block. The procedure is also associated with a postoperative increase in serum K + values. We propose a mechanism involving distortion of the posterior hypothalamus, which accounts for the bradycardia and postoperative hyperkalemia.

In this regard, the analysis of the effectiveness of a combination regimen of 74 patients with valvular congenital heart diseases complicated with infective endocarditis. Given the indications for surgical correction operative technique features and possible technical difficulties in carrying out such operations, due to the inflammatory changes and tissue destruction, and ways to overcome them. For the correction of metabolic disorders in the postoperative period, 47 patients (main group) was appointed Reamberin: once, intravenous drip 400 ml/day during the first 5 days after surgery. 27 patients (control group) was conducted infusion therapy depending on the severity of the condition according to the classical scheme. In addition to standard clinical and laboratory examination, to assess the effectiveness of Reamberin was investigated catalase activity of CPK in blood serum in the dynamics of observation (1, 3 and 5 days after surgery). It is revealed that surgical approach, used in complex treatment of patients with valvular congenital heart diseases, including reorganization of the cavities of the heart, increasing the frequency of joints and the use of reinforcing strips of synthetic material that prevents the cutting of sutures through the inflamed tissue has achieved good short-and long-term results.

    The optimal methods of prophylaxis and therapy of postoperative respiratory complications in surgical patients are still open to discussion. In spite of numerous recent clinical investigations, there is still no specific and universally acceptable therapeutic concept. In our department, we identify patients at risk of pulmonary complications by adequate screening, i.e. medical history, physical examination, chest X-ray, and spirometry. In the postoperative period there are a sequence of stages starting with early mobilization, respiratory therapy (including incentive spirometry and IPPB), and when necessary, controlled mechanical ventilation. We have measured and documented the flows and volumes required of patients using various types of incentive spirometer. In addition, we review on the literature and describe our experience with the technique, handling, and organization of sustained maximal inspiration (SMI). After thoracic or major upper abdominal surgery, all lung volumes decrease due to impairment of rib cage movement, changes in chest wall muscle tone, an increase in lung recoil, and airway closure. At the end of each expiration some of the smallest airways collapse either partly or totally. This process continues to some extent until, normally, a deep breath recruits the alveoli. Sighs to the limit of total lung capacity or oscillations of the expiratory baseline ought to be responsible for this effect in healthy humans; the same purpose is intended in incentive spirometry. For this therapy, it is mandatory that the central airways are not occluded by mucus and that the patient is able to breath volumes exceeding his normal tidal volume.(ABSTRACT TRUNCATED AT 250 WORDS)

    BACKGROUND Based on our laboratory work and clinical trials we hypothesised that radiotherapy after lumpectomy for breast cancer could be restricted to the tumour bed. In collaboration with the industry we developed a new radiotherapy device and a new surgical operation for delivering single-dose radiation to the tumour bed - the tissues at highest risk of local recurrence. We named it TARGeted Intraoperative radioTherapy (TARGIT). From 1998 we confirmed its feasibility and safety in pilot studies. OBJECTIVE To compare TARGIT within a risk-adapted approach with whole-breast external beam radiotherapy (EBRT) over several weeks. DESIGN The TARGeted Intraoperative radioTherapy Alone (TARGIT-A) trial was a pragmatic, prospective, international, multicentre, non-inferiority, non-blinded, randomised (1 : 1 ratio) clinical trial. Originally, randomisation occurred before initial lumpectomy (prepathology) and, if allocated TARGIT, the patient received it during the lumpectomy. Subsequently, the postpathology stratum was added in which randomisation occurred after initial lumpectomy, allowing potentially easier logistics and a more stringent case selection, but which needed a reoperation to reopen the wound to give TARGIT as a delayed procedure. The risk-adapted approach meant that, in the experimental arm, if pre-specified unsuspected adverse factors were found postoperatively after receiving TARGIT, EBRT was recommended. Pragmatically, this reflected how TARGIT would be practised in the real world. SETTING Thirty-three centres in 11 countries. PARTICIPANTS Women who were aged ≥ 45 years with unifocal invasive ductal carcinoma preferably ≤ 3.5 cm in size. INTERVENTIONS TARGIT within a risk-adapted approach and whole-breast EBRT.

Secondary outcome measures included toxicity and breast cancer-specific and non

    PubMed Central

    2009-01-01

    Background Post-operative pulmonary infection often appears to result from aspiration of pathogens colonizing the oral cavity. It was hypothesized that impaired periodontal status and pathogenic oral bacteria significantly contribute to development of aspiration pneumonia following neurosurgical operations. Further, the prophylactic effects of a single dose preoperative cefazolin on the oral bacteria were investigated. Methods A matched cohort of 18 patients without postoperative lung complications was compared to 5 patients who developed pneumonia within 48 hours after brain surgery. Patients waiting for elective operation of a single brain tumor underwent dental examination and saliva collection before surgery. Bacteria from saliva cultures were isolated and periodontal disease was scored according to type and severity. Patients received 15 mg/kg cefazolin intravenously at the beginning of surgery. Serum, saliva and bronchial secretion were collected promptly after the operation. The minimal inhibitory concentrations of cefazolin regarding the isolated bacteria were determined. The actual antibiotic concentrations in serum, saliva and bronchial secretion were measured by capillary electrophoresis upon completion of surgery. Bacteria were isolated again from the sputum of postoperative pneumonia patients. Results The number and severity of coexisting periodontal diseases were significantly greater in patients with postoperative pneumonia in comparison to the control group (p = 0.031 and p = 0.002, respectively). The relative risk of developing postoperative pneumonia in high periodontal score patients was 3.5 greater than in patients who had low periodontal score (p < 0.0001). Cefazolin concentration in saliva and bronchial secretion remained below detectable levels in every patient. Conclusion Presence of multiple periodontal diseases and pathogenic bacteria in the saliva are important predisposing factors of postoperative aspiration pneumonia in patients after

    The objective of this study is to observe the adult growth hormone level in postoperative pituitary tumor patients of multi-centers, and explore the change of hypophyseal hormones in postoperative pituitary tumor patients. Sixty patients with pituitary tumor admitted during March, 2011-March, 2012 were selected. Postoperative hypophyseal hormone deficiency and the change of preoperative, intraoperative, and postoperative growth hormone levels were recorded. Growth hormone hypofunction was the most common hormonal hypofunction, which took up to 85.0 %. Adrenocortical hormone hypofunction was next to it and accounted for 58.33 %. GH + ACTH + TSH + Gn deficiency was the most common in postoperative hormone deficiency, which took up to 40.00 %, and GH + ACTH + TSH + Gn + AVP and GH deficiencies were next to it and accounted for 23.33 and 16.67 %, respectively. The hormone levels in patients after total pituitary tumor resection were significantly lower than those after partial pituitary tumor resection, and the difference was statistically significant; growth hormone and serum prolactin levels after surgery in two groups were decreased, and the difference was statistically significant. The incidence rate of growth hormone deficiency in postoperative pituitary tumor patients is high, which is usually complicated with deficiency of various hypophyseal hormones. In clinical, we should pay attention to the levels of the hypopnyseal hormones, and take timely measures to avoid postoperative complications.

In the control group the arterial pressure was maintained within the patients' normal ranges, while in the study group pentolinium was administered i.v. (average 22 mg per patient) to achieve and maintain a mean arterial pressure of 50 mm Hg (+/-10 SEM). In the normotensive group the blood sugar concentration increased markedly and significantly during surgery and in the early postoperative period while the serum K+ concentration was essentially unchanged. In the hypotensive group pentolinium produced a striking modification of the surgery-induced hyperglycaemic response (but not to hypoglycaemic values) as well as a small but significant decrease in serum K+ concentration. The observed increase in the blood sugar concentration may be part of the autonomic response to surgical stress. Two mechanisms can explain the reduction in serum K+ concentration: (1) decreased hepatic glycogenolysis and (2) attenuation of the suppressive effect of adrenaline on insulin release, both effects being secondary to the ganglion-blocking property of pentolinium. These results are in contrast to the widely held belief that ganglion-blocking drugs cause hypoglycaemia.

    Ischemia is a major cause of flap failure in reconstructive surgery. To detect circulatory compromise, many flap monitoring methods are used; however, there is no any optimal standard method. Ischemia-modified albumin (IMA) is an ischemia marker, which has recently been investigated in many studies and largely validated for early detection of ischemia. In this study, we investigated possible relationship between muscle flap viability and serum IMA levels in experimental flap model. The rectus abdominis muscle flap model was used in 18 New Zealand white rabbits. The study was planned using 3 groups. In group 1, the rectus abdominis muscle flap was harvested as a superior pedicle-based flap in which the inferior pedicle was sacrificed. In group 2, the flap was harvested by severing the superior pedicle. Both pedicles were harvested in group 3. Serum IMA levels were measured before the procedure and 1 hour, 6 hours, and 7 days postoperatively and then compared. In group 3, in which the ischemia was evident, and in group 1, IMA levels were significantly high 1 hour postoperatively (P < 0.05). There was no other significant difference in any of the other studied parameters between the groups. In conclusion, IMA can be used as a biochemical parameter for monitoring muscle flap viability.

    Objectives Pulmonary dysfunction is a recognized postoperative complication that may be linked to use of cardiopulmonary bypass. The off-pump technique of coronary artery bypass aims to avoid some of the complications that may be related to cardiopulmonary bypass. In this study, we compared the influence of on-pump or off-pump coronary artery bypass on pulmonary gas exchange following routine surgery. Methods Fifty patients (mean age 60.4 ± 8.4 years) with no preexisting lung disease and good left ventricular function undergoing primary coronary artery bypass grafting were prospectively randomized to undergo surgery with or without cardiopulmonary bypass. Alveolar/arterial oxygen pressure gradients were calculated prior to induction of anesthesia while the patients were breathing room air, and repeated postoperatively during mechanical ventilation and after extubation while inspiring 3 specific fractions of oxygen. Results Baseline preoperative arterial blood gases and alveolar/arterial oxygen pressure gradients were similar in both groups. At both postoperative stages, the partial pressure of arterial oxygen and alveolar/arterial oxygen pressure gradients increased with increasing fraction of inspired oxygen, but there were no statistically significant differences between patients who underwent surgery with or without cardiopulmonary bypass, either during ventilation or after extubation. Conclusions Off-pump surgery is not associated with superior pulmonary gas exchange in the early postoperative period following routine coronary artery bypass grafting in patients with good left ventricular function and no preexisting lung disease.

    Dietary lutein intake is postulated to interfere with the development of age-related macular degeneration (AMD). Because egg yolk-derived lutein has a high bioavailability, long-term consumption of lutein-enriched eggs might be effective in preventing AMD development, but alternatively might increase cardiovascular disease risk. Here, we report the effect of 1-y daily consumption of a buttermilk drink containing 1.5 lutein-rich egg yolks on serum lipid and lipoprotein and plasma lutein concentrations. Additionally, subgroups that could potentially benefit the most from the intervention were identified. Men and women who had early signs of AMD in at least 1 eye, but were otherwise healthy, participated in a 1-y randomized, placebo-controlled parallel intervention trial. At the start of the study, 101 participants were included: 52 in the experimental (Egg) group and 49 in the control (Con) group. Final analyses were performed with 45 participants in the Egg group and 43 participants in the Con group. As expected, the increase in plasma lutein concentrations in the Egg group was 83% higher than that in the Con group (P < 0.001). Changes in serum total, HDL, and LDL cholesterol, as well as the ratio of total cholesterol to HDL cholesterol, were not different between the 2 groups. Interestingly, participants classified as cholesterol absorbers had higher serum HDL cholesterol concentrations than participants classified as cholesterol synthesizers or participants with average campesterol-to-lathosterol ratios (P < 0.05) at baseline. In addition, cholesterol absorbers had a 229% higher increase in plasma lutein concentrations than participants who were classified as having an average campesterol-to-lathosterol ratio upon consumption of the lutein-enriched egg yolk drink (P < 0.05). Moreover, the change in serum HDL cholesterol upon consumption was significantly different between these 3 groups (P < 0.05). We suggest that cholesterol absorbers particularly might benefit

    Objectives The aim of this study was to identify risk factors associated with postoperative delirium in patients undergoing urological surgery. Methods We prospectively evaluated pre- and postoperative risk factors for postoperative delirium in consecutive 215 patients who received urological surgery between August 2013 and November 2014. Preoperative factors included patient demographics, comorbidities, and frailty assessment. Frailty was measured by handgrip strength, fatigue scale of depression, fall risk assessment, and gait speed (the timed Get-up and Go test). Postoperative factors included types of anesthesia, surgical procedure, renal function and serum albumin decline, blood loss, surgery time, highest body temperature, and complications. Uni- and multivariate logistic regression analyses were performed to assess pre- and postoperative predictors for the development of postoperative delirium. Results Median age of this cohort was 67 years. Ten patients (4.7%) experienced postoperative delirium. These patients were significantly older, had weak handgrip strength, a higher fall risk assessment score, slow gait speed, and greater renal function decline compared with patients without delirium. Multivariate analysis revealed slow gait speed (>13.0 s) and rapid renal function decline (>30%) were independent risk factors for postoperative delirium. Conclusions Slow gait speed and rapid renal function decline after urological surgery are significant factors for postoperative delirium. These data will be helpful for perioperative patient management. This study was registered as a clinical trial: UMIN: R000018809. PMID:27145178

    An experiment was designed to find the suitable acellular bovine pericardium (ABP) patch in pericardial cavity reconstruction and to evaluate the effect of sodium hyaluronic acid (NaHA) on inflammatory reaction in prevention of pericardial adhesions. The pericardial adhesion model was established in 20 rabbits, weighing from 3.2 to 3.6 kg. Groups were classified as follows: Group A (n = 5), the control group, the pericardium was directly closed; Group B (n = 5), 0.15% glutaraldehyde-treated ABP (low cross-link degree); Group C, 0.3% glutaraldehyde-treated ABP (middle cross-link degree); Group D, 0.15% glutaraldehyde-treated ABP + NaHA solution. Blood samples were collected at 6 h, 24 h, 3 days, and 5 days, to assay postoperative inflammatory reaction. The tenacity and severity of adhesions were evaluated 2 months after operation, by macroscopic and microscopic examinations, and Q-PCR (real-time quantitative polymerase chain reaction) test was used to quantitatively analyze the associated genes with adhesion. Pericardium regeneration was demonstrated by immunohistochemical technique to identify mesothelial cells. In Group D, the serum concentration of tumor necrosis factor-α (TNF-α) was significantly lower in the early postoperative period, and the mean adhesion score (adhesion between the epicardium and ABP) was significantly lower compared with the control group (Groups D vs. A: 0.20 ± 0.45 vs. 2.00 ± 0.71, P = 0.009*). The signs of degradation of the ABPs were observed 2 months postoperation in Groups D and B. Immunohistochemically, the positive cytokeratin AE1 staining results demonstrated the relatively total regeneration of the pericardium in Group D. Signs of regeneration were observed in Group D. Compared with the control group, the level of TGF-β2 in Group D was significantly lower (0.00132 ± 0.00114, P = 0.022*). The TGF-β3 level was statistically significant, being highest in Group D (0.00805 ± 0.00136, P = 0.029*). The mean quantity of Smad6 in

    Immunogenicity assessment during early stages of nonclinical biotherapeutic development is not always warranted. It is rarely predictive for clinical studies and evidence for the presence of anti-drug antibodies (ADAs) may be inferred from the pharmacokinetic (PK) profile. However, collecting and banking samples during the course of the study are prudent for confirmation and a deeper understanding of the impact on PK and safety. Biotherapeutic-specific ADA assays commonly developed can require considerable time and resources. In addition, the ADA assay may not be ready when needed if the study of PK and safety data triggers assay development. During early stages of drug development for antibody-drug conjugates (ADCs), there is the added complication of the potential inclusion of several molecular variants in a study, differing in the linker and/or drug components. To simplify analysis of ADAs at this stage, we developed plug-and-play generic approaches for both the assay format and the data analysis steps. Firstly, the assay format uses generic reagents to detect ADAs. Secondly, we propose a cut point methodology based on animal specific baseline variability instead of a population data approach. This assay showed good sensitivity, drug tolerance, and reproducibility across a variety of antibody-derived biotherapeutics without the need for optimization across molecules. PMID:27092313

    Purpose Epigenetic alterations measured in blood may help guide breast cancer treatment. The multisite prospective study TBCRC 005 was conducted to examine the ability of a novel panel of cell-free DNA methylation markers to predict survival outcomes in metastatic breast cancer (MBC) using a new quantitative multiplex assay (cMethDNA). Patients and Methods Ten genes were tested in duplicate serum samples from 141 women at baseline, at week 4, and at first restaging. A cumulative methylation index (CMI) was generated on the basis of six of the 10 genes tested. Methylation cut points were selected to maximize the log-rank statistic, and cross-validation was used to obtain unbiased point estimates. Logistic regression or Cox proportional hazard models were used to test associations between the CMI and progression-free survival (PFS), overall survival (OS), and disease status at first restaging. The added value of the CMI in predicting survival outcomes was evaluated and compared with circulating tumor cells (CellSearch). Results Median PFS and OS were significantly shorter in women with a high CMI (PFS, 2.1 months; OS, 12.3 months) versus a low CMI (PFS, 5.8 months; OS, 21.7 months). In multivariable models, among women with MBC, a high versus low CMI at week 4 was independently associated with worse PFS (hazard ratio, 1.79; 95% CI, 1.23 to 2.60; P = .002) and OS (hazard ratio, 1.75; 95% CI, 1.21 to 2.54; P = .003). An increase in the CMI from baseline to week 4 was associated with worse PFS ( P < .001) and progressive disease at first restaging ( P < .001). Week 4 CMI was a strong predictor of PFS, even in the presence of circulating tumor cells ( P = .004). Conclusion Methylation of this gene panel is a strong predictor of survival outcomes in MBC and may have clinical usefulness in risk stratification and disease monitoring.

    In the postoperative patient ordinary radiographs of the spine generally add very little information, revealing the usual postoperative bone changes and often postoperative narrowing of the intervertebral space. Myelography may sometimes be informative, showing evidence of focal arachnoiditis or a focal defect at the surgical site. However, the latter finding is difficult to interpret. As experience with high-resolution CT scanning of the lumbar spine has been increasing, it is becoming apparent that this noninvasive and easily performed study can give considerably more information about the postoperative spine than any of the other current imaging methods. About 750 patients with previous lumbar laminectomies had CT scanning within a 28 month period.

    Our aim was to analyze the correlation of early postoperative cortisol levels in patients after transsphenoidal pituitary adenoma surgery compared to the standard dose ACTH test and Insulin tolerance test (ITT) several months later. We retrospectively reviewed data from 94 patients operated for pituitary adenoma in years 2009-2012. The comparison of day 7 (median) postoperative basal cortisol levels and 3.6 months (median) after pituitary adenoma surgery stimulation test - standard dose 250 microg 1-24ACTH test in 83 patients or ITT in 11 patients were performed. All 16 patients with early postoperative cortisol levels >500 nmol/l proved a sufficient response in the stimulation tests. At basal cortisol levels of 370-500 nmol/l the sufficient response was found in 96 % (27/28) of patients. In the postoperative basal cortisol levels 200-370 nmol/l we found a preserved corticotroph axis later on in 88 % (28/32) of cases. Patients with basal cortisol levels 100-200 nmol/l had a maintained corticotroph axis function in 8/11 cases - 73 %. All patients with an early postoperative basal cortisol level above 500 nmol/l proved in the stimulation tests a preserved corticotroph axis function. The interval 370-500 nmol/l showed a minimal risk of postoperative adrenal insufficiency.

    OBJECTIVE: The present study evaluated effects of incidental parathyroidectomy, surgical technique, and presence of thyroiditis or hyperthyroidism on occurrence of postoperative persistent or transient hypocalcemia. METHODS: Patients who underwent thyroidectomy at İstanbul Medeniyet University between 2013 and 2015 were included in the study. Patient information, postoperative serum calcium levels, and pathology reports were investigated retrospectively. Group 1 was made up of patients who were found to have hypocalcemia (calcium ≤8.5 mg/dL) according to postoperative serum level and normocalcemic patients were placed in Group 2. Groups were compared statistically in terms of rate of incidental parathyroidectomy, surgical technique, and presence of thyroiditis or hyperthyroidism. RESULTS: Mean age was 49.8±12.8 years (range: 20-88). A total of 417 patients were included in the study, 74 (17.7%) were male and 343 (82.3%) were female. Group 1 consisted of 205 (49.2%) patients who had hypocalcemia according to postoperative serum level, and remaining 212 (50.8%) patients were placed in Group 2. In Group 1, 38 (18.5%) patients had incidental parathyroidectomy, and with only 18 (8.5%) patients in Group 2, a statistically significant relationship was found between incidental parathyroidectomy and hypocalcemia (p=0.003). There was no statistically significant difference in terms of presence of thyroiditis or hyperthyroidism between groups. There was statistically significant decrease in postoperative hypocalcemia rate in patients with lobectomy compared to patients with bilateral total thyroidectomy or central neck dissection (p<0.01). CONCLUSION: Risk of postoperative hypocalcemia may be reduced with lobectomy for selected patients. In addition, delicate dissection during thyroidectomy is important in order to protect parathyroid glands and prevent hypocalcemia. PMID:28058379

    Objective To examine the predictive significance of 2 pneumoproteins, surfactant protein D (SP-D) and CC-chemokine ligand 18 (CCL18), for the course of systemic sclerosis (SSc)-related interstitial lung disease. Methods The pneumoproteins were determined in the baseline plasma samples of 266 patients with early SSc enrolled in the GENISOS observational cohort. They also were measured in 83 followup patient samples. Pulmonary function tests were obtained annually. The primary outcome was decline in forced vital capacity (FVC percentage predicted) over time. The predictive significance for longterm change in FVC was investigated by a joint analysis of longitudinal measurements (sequentially obtained FVC percentage predicted) and survival data. Results SP-D and CCL18 levels were both higher in patients with SSc than in matched controls (p < 0.001 and p = 0.015, respectively). Baseline SP-D levels correlated with lower concomitantly obtained FVC (r = −0.27, p < 0.001), but did not predict the short-term decline in FVC at 1 year followup visit or its longterm decline rate. CCL18 showed a significant correlation with steeper short-term decline in FVC (p = 0.049), but was not a predictor of its longterm decline rate. Similarly, a composite score of SP-D and CCL18 was a significant predictor of short-term decline in FVC but did not predict its longterm decline rate. Further, the longitudinal change in these 2 pneumoproteins did not correlate with the concomitant percentage change in FVC. Conclusion SP-D correlated with concomitantly obtained FVC, while CCL18 was a predictor of short-term decline in FVC. However, neither SP-D nor CCL18 was a longterm predictor of FVC course in patients with early SSc. PMID:23588945

    Despite the availability of biological drugs and the widespread and earlier use of immunosuppressants, intestinal resection remains necessary in almost half of the patients with Crohn's disease. The development of new mucosal lesions in previously unaffected intestinal segments (a phenomenon known as post-operative recurrence, POR) occur within the first year in up to 80% if no preventive measure is started soon after resectional surgery, leading to clinical manifestations (clinical recurrence) and even needing new intestinal resection (surgical recurrence) in some patients. That is the reason why endoscopic monitoring has been recommended within 6 to 12 months after surgery. Active smoking is the only indisputable risk factor for early POR development. Among several evaluated drugs, only thiopurine and anti-tumor necrosis factor therapy seem to be effective and feasible in the long-term both for preventing or even treating recurrent lesions, at least in a proportion of patients. However, to date, it is not clear which patients should start with one or another drug right after surgery. It is also not well established how and how often POR should be assessed in patients with a normal ileocolonoscopy within the first 12 months.

    Background The treatment of ulcerative colitis (UC) patients with moderate to severe inflammatory activity with anti-tumor necrosis factor alpha (TNFα) antibodies leads to a clinical remission rate of 10% after 8 weeks of therapy. However, it must be taken into account that patient selection in clinical trials clearly influences both response and remission rates. An unsatisfactory response to anti-TNFα medication after week 12 often leads to a discontinuation of treatment. The early prediction of clinical response could therefore help optimize therapy and potentially avoid ineffective treatments. Objective The aim of this study is to develop an algorithm for optimizing golimumab administration in patients with moderate to severe UC by calculating the probability of clinical response in Week 26 based on data from Week 6. Methods The study is designed as a prospective, single-arm, multicenter, non-interventional observational study with no interim analyses and a sample size of 58 evaluable patients. The primary outcome is the prediction of clinical response in Week 26 based on a 50% reduction in fecal calprotectin and a positive golimumab trough level in Week 6. Results Enrollment started in October 2014 and was still open at the date of submission. The study is expected to finish in December 2016. Conclusions The early identification of patients who are responding to an anti-TNFα antibody is therapeutically beneficial. At the same time, patients who are not responding can be identified earlier. The development of a therapeutic algorithm for identifying patients as responders or non-responders can thus help prescribing physicians to both avoid ineffective treatments and adjust dosages when necessary. This in turn promotes a higher degree of treatment tolerance and patient safety in the case of anti-TNFα antibody administration.

    Comparative estimation of results for endoscopic lifting of the face upper part in dynamics of early and late postoperative period was adduced. In accordance to results of analysis, concerning the eyebrows height in a control terms, there was established, that through one year postoperatively the eyebrows have a tendency towards ptosis due to activity of the eyes circular muscles. Deterioration of the result achieved post-operatively is less prominent in patients after preliminary chemical denervation of mimic muscles. Chemical denervation of the eyes circular muscles, using injections of botulinic toxine type A before 2 weeks preoperatively secures a stable fixation of tissues in early postoperative period, what permits to escape loss of the result achieved, secures the results improvement in late postoperative period in 3.7 times.

    Study Objectives: To describe preoperative and postoperative sleep disruption and its relationship to postoperative delirium. Design: Prospective cohort study with 6 time points (3 nights pre-hospitalization and 3 nights post-surgery). Setting: University medical center. Patients: The sample consisted of 50 English-speaking patients ≥ 40 years of age scheduled for major non-cardiac surgery, with an anticipated hospital stay ≥ 3 days. Interventions: None. Measurements and results: Sleep was measured before and after surgery for a total of 6 days using a wrist actigraph to quantify movement in a continuous fashion. Postoperative delirium was measured by a structured interview using the Confusion Assessment Method. Sleep variables for patients with (n = 7) and without (n = 43) postoperative delirium were compared using the unpaired Student t-tests or χ2 tests. Repeated measures analysis of variance for the 6 days was used to examine within-subject changes over time and between group differences. The mean age of the patients was 66 ± 11 years (range 43–91 years), and it was not associated with sleep variables or postoperative delirium. The incidence of postoperative delirium observed during any of the 3 postoperative days was 14%. For the 7 patients who subsequently developed postoperative delirium, wake after sleep onset (WASO) as a percentage of total sleep time was significantly higher (44% ± 22%) during the night before surgery compared to the patients who did not subsequently developed delirium (21% ± 20%, p = 0.012). This sleep disruption continued postoperatively, and to a greater extent, for the first 2 nights after surgery. Patients with WASO < 10% did not experience postoperative delirium. Self-reported sleep disturbance did not differ between patients with vs. without postoperative delirium. Conclusions: In this pilot study of adults over 40 years of age, sleep disruption was more severe before surgery in the patients who experienced postoperative

    Acceptance of lower transfusion thresholds and shorter post-operative stays results in patients leaving hospital after surgery with lower haemoglobin (Hb) than previously. We undertook a prospective observational study to assess the haematological response to post-operative anaemia and to determine the utility of quality of life (QoL) measures in assessing the impact of anaemia on such patients. Thirty patients undergoing unilateral hip arthroplasty had blood samples taken and QoL questionnaires administered pre-operatively and at 7, 28 and 56 days post-operatively. Increased erythropoiesis was evident at day 7 post-operatively. Approximately two-thirds of the post-operative Hb deficit was corrected by day 28. There was evidence of functional iron deficiency in more than one-quarter of patients at day 56. QoL scores used did not show any relationship with Hb in the post-operative period. Red cell 2,3-diphosphoglycerate (2,3DPG) levels increased in proportion to the degree of post-operative anaemia. We concluded that substantial recovery of Hb occurs between day 7 and day 28 post-operatively. Complete recovery of Hb may be delayed beyond day 56 due to development of iron deficiency. Patients are at significant risk of developing post-operative iron deficiency depending on operative blood loss and pre-operative iron stores. Increased red cell 2,3DPG may offset the effect of anaemia on oxygen delivery. We found no evidence that anaemia produces a measurable effect on chosen QoL scores in the post-operative period.

    Lumbar discectomy is the most common surgical procedure performed in neurosurgery clinics. Such a large number of procedures underscore not only the prevalence of conditions such as intervertebral disc herniation, but also the strong belief of surgeons that the operation does provide benefits to patients suffering from sciatica. In spite of this belief, sciatic pain may continue after the surgery. The recurrence of sciatic and/or back pain after primary discectomy is called the "failed back surgery syndrome." The rate of the complications involved in standard lumbar discectomy ranges from 5.4 to 14%. One of the complications of the lumbar disc surgery is nerve root injury. The complication rate of this injury ranges from 0.7 to 2.2%. Postoperative radicular neuroma must be considered in differential diagnosis for the patient who has failed back surgery syndrome. In this study the authors evaluate a patient who had undergone surgery for lumbar disc herniation and suffered intractable pain. A traumatic radicular neuroma is demonstrated and the pertinent literature is presented.

    The catabolic response that commonly occurs after major operation is characterized by net skeletal muscle proteolysis and accelerated nitrogen excretion. This response was absent in patients undergoing cardiac surgical procedures associated with the combination of cardiopulmonary bypass, narcotic anesthesia, neuromuscular blockade, and hypothermia. Forearm nitrogen release was 422 +/- 492 nmol/100 ml X min on the first postoperative day, approximately 25% of preoperative values (1677 +/- 411, p less than 0.05). Nitrogen excretion and the degree of negative nitrogen balance were comparable to levels observed in nonstressed, fasting subjects. The potential role of hypothermia, high-dose fentanyl anesthesia, and neuromuscular blockade in modifying the catabolic response to laparotomy and retroperitoneal dissection was further evaluated in animal studies. Six hours after operation, amino acid nitrogen release from the hindquarter was 84% less than control values (p less than 0.05). Nitrogen excretion and urea production were also reduced compared to normothermic controls. It is concluded that the combination of hypothermia, narcotic anesthesia, and neuromuscular blockade attenuates the catabolic response to injury and thus may be useful in the care of critically ill surgical patients.

    Postoperative surgical site infection (SSI) is a common complication after posterior lumbar spine surgery. This review details an approach to the prevention, diagnosis and treatment of SSIs. Factors contributing to the development of a SSI can be split into three categories: (1) microbiological factors; (2) factors related to the patient and their spinal pathology; and (3) factors relating to the surgical procedure. SSI is most commonly caused by Staphylococcus aureus. The virulence of the organism causing the SSI can affect its presentation. SSI can be prevented by careful adherence to aseptic technique, prophylactic antibiotics, avoiding myonecrosis by frequently releasing retractors and preoperatively optimizing modifiable patient factors. Increasing pain is commonly the only symptom of a SSI and can lead to a delay in diagnosis. C-reactive protein and magnetic resonance imaging can help establish the diagnosis. Treatment requires acquiring intra-operative cultures to guide future antibiotic therapy and surgical debridement of all necrotic tissue. A SSI can usually be adequately treated without removing spinal instrumentation. A multidisciplinary approach to SSIs is important. It is useful to involve an infectious disease specialist and use minimum serial bactericidal titers to enhance the effectiveness of antibiotic therapy. A plastic surgeon should also be involved in those cases of severe infection that require repeat debridement and delayed closure. PMID:23330073

    Responses to surgical stress can be modulated by anesthetics. We prospectively compared the effects of two different anesthetic/sedative techniques on the peak postoperative bladder temperature (BT) and the postoperative C-reactive protein (CRP) level. Twenty patients who were scheduled to undergo elective thoracoabdominal esophagectomy were allocated to receive either propofol anesthesia followed by propofol sedation (PP group, n = 10) or sevoflurane anesthesia followed by midazolam sedation (SM group, n = 10). In each case, the patient's peak bladder temperature was measured on the morning after surgery, and their serum CRP levels were assessed on postoperative days (POD) 1, 2, and 3. The patients' postoperative clinical courses were also evaluated. The peak postoperative BT (degrees C) (37.6 ± 0.4 vs. 38.2 ± 0.6, respectively; p < 0.05) and the CRP level on POD 2 (mg/dl) (14.3 ± 3.9 vs. 20.6 ± 3.9, respectively; p < 0.05) were lower in the PP group than in the SM group. The peak postoperative BT was positively correlated with the CRP level on POD 2 (R = 0.533, p < 0.05). There were no significant differences between the clinical course-related parameters in both groups. Propofol anesthesia and postoperative propofol sedation resulted in a reduced peak postoperative BT and lower CRP levels on POD 2 after esophagectomy than sevoflurane anesthesia followed by midazolam sedation.

    Adequate pain relief after surgery is essential for avoiding pain-associated stress and patient comfort in the postoperative period. The Swedish nurse anesthetist has an important role in the intraoperative management of the surgical patient by assessing and moderating individual physiological response evoked by surgical stimuli during general anesthesia. The extent to which knowledge of specific individual response patterns are used to plan postoperative pain management is unknown. The aim of the present study was to assess the role of the nurse anesthetist in planning early postoperative pain management for surgical patients. Nurse anesthetists (N = 101) at 4 academic hospitals in Sweden responded to a questionnaire focusing, in addition to demographic data, on intraoperative routines for postoperative pain management, perceived clinical relevance of used routines, personal involvement (in addition to existing routines) in postoperative pain management, factors influencing pain alleviation requirements, and the potential role of the nurse anesthetist for improved postoperative pain management. We found that type of anesthesia and type of surgical procedure were both factors considered important for postoperative pain management. A majority of the participants believed that pain management approaches were not appropriately individualized to the patient.

  19. Differences in postoperative opioid consumption in patients prescribed patient-controlled analgesia versus intramuscular injection.

    The purpose of this study was to examine differences in opioid consumption in patients prescribed patient-controlled analgesia (PCA) versus intramuscular injection (IMI) in the early postoperative period after open abdominal surgery. A retrospective audit of 115 patients elicited demographic and clinical data. No significant differences were found between the demographic variables of the PCA and IMI groups. There was a significant difference in the mean opioid dose used during the first 3 postoperative days (p < .01). Mean opioid consumption was 136.89 mg for the PCA group and 50.79 mg for the IMI group. Although there was a reduction in the amount of opioid consumed over the first 3 postoperative days, the PCA group consistently consumed more opioid analgesia compared with the IMI group. Furthermore, there was a disproportionate reduction in opioid consumption between the two groups from Day 1 (r = .34; p < .01) to Day 3 (r = .14; p = .14). This study shows that the amount of analgesia consumed during the postoperative period by patients who had abdominal surgery varied markedly depending on the mode of analgesia (PCA or IMI). The difference in analgesic consumption was also found to increase throughout the 3-day postoperative period. This divergence in the amount of opioid consumption between patients who were prescribed PCA and patients who were prescribed IM analgesia heightens the need for vigilance in assessment and management of pain during the early postoperative period, particularly in patients prescribed IM analgesia on an "as-needed" basis.

    Several benign and malignant liver diseases may require surgical treatment for cure, including anatomical resections based on the segmental anatomy of the liver, non-anatomical (wedge) resections, and surgical management of biliary cysts. The type of surgery depends not only on the location and the nature of the disease, but also on the expertise of the surgeon. Whereas ultrasonography is often the first-line imaging examination in case of suspected postoperative complication, multidetector computed tomography (MDCT) is of greater value for identifying normal findings after surgery, early postoperative pathologic fluid collections and vascular thromboses, and tumor recurrence in patients who have undergone hepatic surgery. Magnetic resonance cholangiopancreatography (MRCP) is the imaging modality of choice for depicting early postoperative bile duct injuries and ischemic cholangitis that may occur in the late postoperative phase. Both MDCT and MRCP can accurately depict tumor recurrence. Radiologists should become familiar with these surgical procedures to better understand postoperative changes, and with the normal imaging appearances of various postoperative complications to better differentiate between complications and normal findings.

    Neonates with critical congenital heart disease (CCHD) are vulnerable to malnutrition during the post-operative period due to hypermetabolism and hypercatabolism. To improve nutritional outcomes during hospitalization, a nurse led post-operative enteral feeding protocol was implemented at a large U.S. children's hospital. During an eight-month implementation period, twenty-one neonates met protocol inclusion criteria. Days for neonates to achieve goal caloric feedings (120kcal/kg/day) were decreased. A one-way repeated measures analysis of variance showed serum albumin levels and serial anthropometric measurements improved significantly throughout hospitalization (p<0.005). Results from this quality improvement project show standardizing nutritional care for neonates with CCHD during the post-operative period is an effective way to improve nutritional outcomes and shorten length of hospital stay.

    Transdermal scopolamine, a patch system that delivers 1.5 mg of scopolamine gradually over 72 hours following an initial bolus, was approved in the United States in 2001 for the prevention of postoperative nausea and vomiting (PONV) in adults. Scopolamine (hyoscine) is a selective competitive anatagonist of muscarinic cholinergic receptors. Low serum concentrations of scopolamine produce an antiemetic effect. Transdermal scopolamine is effective in preventing PONV versus placebo [relative risk (RR)=0.77, 95% confidence interval (CI), 0.61-0.98, P = 0.03] and a significantly reduced risk for postoperative nausea (RR=0.59, 95% CI, 0.48-0.73, P < 0.001), postoperative vomiting (RR=0.68, 95% CI, 0.61-0.76, P < 0.001), and PONV (RR 0.73, 95% CI, 0.60-0.88, P = 001) in the first 24 hours after the start of anesthesia.

    Numerous factors need to be taken into account when managing a patient with Parkinson's disease (PD) after deep brain stimulation (DBS). Questions such as when to begin programming, how to conduct a programming screen, how to assess the effects of programming, and how to titrate stimulation and medication for each of the targeted sites need to be addressed. Follow-up care should be determined, including patient adjustments of stimulation, timing of follow-up visits and telephone contact with the patient, and stimulation and medication conditions during the follow-up assessments. A management plan for problems that can arise after DBS such as weight gain, dyskinesia, axial symptoms, speech dysfunction, muscle contractions, paresthesia, eyelid, ocular and visual disturbances, and behavioral and cognitive problems should be developed. Long-term complications such as infection or erosion, loss of effect, intermittent stimulation, tolerance, and pain or discomfort can develop and need to be managed. Other factors that need consideration are social and job-related factors, development of dementia, general medical issues, and lifestyle changes. This report from the Consensus on Deep Brain Stimulation for Parkinson's Disease, a project commissioned by the Congress of Neurological Surgeons and the Movement Disorder Society, outlines answers to a series of questions developed to address all aspects of DBS postoperative management and decision-making with a systematic overview of the literature (until mid-2004) and by the expert opinion of the authors. The report has been endorsed by the Scientific Issues Committee of the Movement Disorder Society and the American Society of Stereotactic and Functional Neurosurgery.

    Postoperative nausea and vomiting (PONV) is a complication affecting between 20 and 40% of all surgery patients, with high-risk patients experiencing rates of up to 80%. Recent studies and publications have shed light on the uses of alternative treatment for PONV through their modulation of endogenous opioid neuropeptides and neurokinin ligands. In addition to reducing PONV, hypnosis was reported to be useful in attenuating postoperative pain and anxiety, and contributing to hemodynamic stability. Music therapy has been utilized to deepen the sedation level and decrease patient anxiety, antiemetic and analgesic requirements, hospital length of stay, and fatigue. Isopropyl alcohol and peppermint oil aromatherapy have both been used to reduce postoperative nausea. With correct training in traditional Chinese healing techniques, acupuncture (APu) at the P6 acupoint has also been shown to be useful in preventing early PONV, postdischarge nausea and vomiting, and alleviating of pain. Electro-acupuncture (EAPu), as with APu, provided analgesic and antiemetic effects through release and modulation of opioid neuropeptides. These non-pharmacological modalities of treatment contribute to an overall patient wellbeing, assisting in physical and emotional healing.

    A 53-year-old Caucasian man underwent femtosecond cataract surgery and then presented with pain and hand motions vision 1 day following surgery. Anterior segment examination showed a 2-mm-layered hypopyon, a well-centered intraocular lens in the sulcus, and an obscured view to the fundus. B-scan ultrasonography showed significant vitritis and that the retina was attached. A tap and an injection of vancomycin 1 mg per 0.1 ml and of ceftazidime 2.25 mg per 0.1 ml were performed. The tap eventually yielded culture results positive for Staphylococcus haemolyticus, which was sensitive to vancomycin. We report a case of endophthalmitis that occurred on postoperative day 1 following complicated cataract surgery. This is an uncommon bacterium that is not widely reported in the literature as a cause of endophthalmitis in the postoperative period. We urge clinicians to consider S. haemolyticus as an offending agent, especially when the infection presents very early and aggressively in the postoperative period. PMID:26951642

    In past decades, the surgical techniques for treating laryngeal carcinoma have been vastly improved. For circumscribed tumors, voice-conserving resections are possible and for extensive neoplasms, radical laryngectomy, sometimes combined with chemoradiation, has been developed. Postoperative complications regarding swallowing function are not uncommon. Radiologic examinations, especially pharyngography and videofluoroscopy, are most often used to evaluate patients with complications after laryngeal surgery. An optimized videofluoroscopic technique for evaluation of complications is described. The radiologic appearance of early and late complications, such as fistulas, hematomas, aspiration, strictures, dysfunction of the pharyngoesophageal sphincter, tumor recurrence, and metachronous tumors is demonstrated.

    Abstract The aim was to evaluate the nutritional situation of patients admitted to the Postoperative Acute Care Unit using classic methods of objective anthropometry, systemic evaluation methods, and Nutrition Risk in Critically Ill (NUTRIC) score, and to compare them as a predictor of morbidity and mortality. At admission to the postoperative care unit, patients undergoing various surgeries were assessed for the following items: Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Nutritional Risk Screening (NRS)-2002, Mini Nutritional Assessment (MNA), Charlson comorbidity index (CCI), and NUTRIC score, anthropometric measurements, serum total protein, serum albumin, and lymphocyte count. Patients were monitored for postoperative complications until death or discharge. Correlation of complications with these parameters was also analyzed. A total of 152 patients were included in the study. In this study a positive correlation was determined between mortality and NRS-2002, SGA, CCI, Acute Physiology and Chronic Health Evaluation , Sepsis-related Organ Failure Assessment, and NUTRIC score, whereas a negative correlation was determined between mortality and NRI. There was a correlation between NUTRIC score and pneumonia, development of atrial fibrillation, delirium, renal failure, inotrope use, and duration of mechanical ventilation. In our study group of postoperative patients, MNA had no predictive properties for any complication, whereas SGA had no predictive properties for any complications other than duration of hospital stay and mortality. The NUTRIC score is an important indicator of mortality and morbidity in postoperative surgical patients. NRI correlated with many postoperative complications, and though SGA and NRS were correlated with mortality, they were not correlated with the majority of complications. MNA was determined not to have any correlation with any complication, mortality, and duration of hospital stay in our patient group. PMID

    Background: The main advantages of video assisted thoracoscopic surgery (VATS) include less post-operative pain, rapid recovery, less postoperative complications, shorter hospital stay and early discharge. Although pain intensity is less as compared to conventional thoracotomy but still patients experience upto moderate pain postoperatively. The objective of this study was to assess the efficacy and morphine sparing effect of intercostal nerve block in alleviating immediate post-operative pain in patients undergoing VATS. Materials and Methods: Sixty ASA I-III patients, aged between 16 to 60 years, undergoing mediastinal lymph node biopsy through VATS under general anaesthesia were randomly divided into two groups. The intercostal nerve block (ICNB group) received the block along with patient control intravenous analgesia (PCIA) with morphine, while control group received only PCIA with morphine for post-operative analgesia. Patients were followed for twenty four hours post operatively for intervention of post-operative pain in the recovery room and ward. Results: The pain was assessed using visual analogue scale (VAS) at 1, 6, 12 and 24 hours. There was a significant decrease in pain score and morphine consumption in ICNB group as compared to control group in first 6 hours postoperatively. There was no significant difference in pain scores and morphine consumption between the two groups after 6 hours. Conclusion: Patients receiving intercostal nerve block have better pain control and less morphine consumption as compared to those patients who did not receive intercostal nerve block in early (6 hours) post-operative period.

    Previous data have shown that preoperative analgesia may reduce postoperative analgesic demands. The aim of the current study was to determine if preincisional ropivacaine infiltration may reduce postoperative oral pain in infants and small children undergoing elective cleft palate patients.Twenty nonsyndromic cleft palate patients were randomly divided into 2 groups. Injection with ropivacaine hydrochloride, at dose of 0.2 mg/kg, was performed by submucous infiltration of the proposed incisional site groups of patients. In control group, no medication was given before cleft palate repair under general anesthesia. Postoperative pain scores were measured according to Children and Infants Postoperative Pain Scale. Heart rate recordings and noninvasive blood pressure measurements were also done in all the patients.Measurements of Children and Infants Postoperative Pain Scale scores at all the observational postoperative periods showed significantly favorable values in ropivacaine group than in control group (P < 0.05). Six patients in the control group required rescue analgesia, whereas 2 patients required analgesic therapy in the treatment group.Preemptive analgesia using ropivacaine may enhance early postoperative comfort by reducing early postoperative pain in primary cleft repair.

    This study was to evaluate the risk factors of infectious complications after percutaneous nephrolithotomy (PCNL) and build a prediction tool for postoperative complications based on the risk factors. A total of 110 male (67.1%) and 54 female (32.9%) patients who underwent PCNL for renal stones between 2010 and 2014 in our institute were included. A detailed clinical information and laboratory results were obtained from patients. Systemic inflammatory response syndrome (SIRS) and postoperative fever were recorded after PCNL surgery. In all, 45 cases (27.4%) developed SIRS and fever was observed in 20 cases (12.2%). In multivariate analysis, stone size (odds ratio, OR = 1.471, p = 0.009) and urine white blood cell (WBC) (OR = 1.001, p = 0.007) were related to the development of SIRS. Stone size (OR = 1.644, p = 0.024), urine WBC (OR = 1.001, p = 0.002) and serum albumin (OR = 0.807, p = 0.021) were associated with postoperative fever. We concluded that patients with larger stone size and preoperative urinary tract infection might have a higher risk of developing SIRS and fever after operation, while a high-normal level of serum albumin might be the protective factor for postoperative fever.

Patients over the age of 65 years receive greater than 1/3 of the over 40 million anesthetics delivered yearly in the United States. This number is expected to increase with the aging of the population. Thus, it is increasingly important that perioperative clinicians who care for geriatric patients have an understanding of the complex syndrome of postoperative delirium. PMID:26315635

    Osteoarthritis (OA) is a degenerative process involving the progressive loss of articular cartilage, synovial inflammation and structural changes in subchondral bone that lead to loss of synovial joint structural features and functionality of articular cartilage. OA represents one of the most common causes of physical disability in the world. Different OA treatments are usually considered in relation to the stage of the disease. In the early stages, it is possible to recommend physical activity programs that can maintain joint health and keep the patient mobile, as recommended by OA Research Society International (OARSI) and European League Against Rheumatism (EULAR). In the most severe and advanced cases of OA, surgical intervention is necessary. After, in early postoperative stages, it is essential to include a rehabilitation exercise program in order to restore the full function of the involved joint. Physical therapy is crucial for the success of any surgical procedure and can promote recovery of muscle strength, range of motion, coordinated walking, proprioception and mitigate joint pain. Furthermore, after discharge from the hospital, patients should continue the rehabilitation exercise program at home associated to an appropriate diet. In this review, we analyze manuscripts from the most recent literature and provide a balanced and comprehensive overview of the latest developments on the effect of physical exercise on postoperative rehabilitation in OA. The literature search was conducted using PubMed, Scopus, Web of Science and Google Scholar, using the keywords ‘osteoarthritis’, ‘rehabilitation’, ‘exercise’ and ‘nutrition’. The available data suggest that physical exercise is an effective, economical and accessible to everyone practice, and it is one of the most important components of postoperative rehabilitation for OA.

    Early life events can significantly alter the development of the nociceptive circuit. In fact, clinical work has shown that maternal adversity, in the form of depression, and concomitant selective serotonin reuptake inhibitor (SSRI) treatment influence nociception in infants. The combined effects of maternal adversity and SSRI exposure on offspring nociception may be due to their effects on the developing hypothalamic-pituitary-adrenal (HPA) system. Therefore, the present study investigated long-term effects of maternal adversity and/or SSRI medication use on nociception of adult Sprague-Dawley rat offspring, taking into account involvement of the HPA system. Dams were subject to stress during gestation and were treated with fluoxetine (2×/5 mg/kg/day) prior to parturition and throughout lactation. Four groups of adult male offspring were used: 1. Control+Vehicle, 2. Control+Fluoxetine, 3. Prenatal Stress+Vehicle, 4. Prenatal Stress+Fluoxetine. Results show that post-operative pain, measured as hypersensitivity to mechanical stimuli after hind paw incision, was decreased in adult offspring subject to prenatal stress alone and increased in offspring developmentally exposed to fluoxetine alone. Moreover, post-operative pain was normalized in prenatally stressed offspring exposed to fluoxetine. This was paralleled by a decrease in corticosteroid binding globulin (CBG) levels in prenatally stressed offspring and a normalization of serum CBG levels in prenatally stressed offspring developmentally exposed to fluoxetine. Thus, developmental fluoxetine exposure normalizes the long-term effects of maternal adversity on post-operative pain in offspring and these effects may be due, in part, to the involvement of the HPA system.

    Stored serum samples can be an important research resource into the etiology of cancer. These sera cannot be replaced and should therefore be used to best advantage. In previous epidemiologic studies, only single serum constituents have been assayed in individual serum samples. For example, serum ferritin has been examined in samples stored for as long as 10 years at -20C for a possible relation with general mortality (1) and cancer death (2). Ferritin is the tissue iron-storage protein and is therefore subject to denaturation. Serum selenium has also been examined in relation to cancer risk in a prospective manner by using stored frozen serum samples (3, 4). The interactions of a variety of serum factors in relation to cancer risk would be a desirable research goal, except that the amounts of serum typically available in frozen serum banks are less than 1 ml. It was the purpose of this investigation to determine if a radioimmunoassay for ferritin affected a subsequent neutron activation assay for selenium on the same 0.1 ml serum sample.

    Pulmonary dysfunction with impairment of lung function and oxygenation is one of the most serious problems in the early postoperative period after cardiac surgery. In this study we investigated the effect of alveolar recruitment strategy during cardiopulmonary bypass on postoperative gas exchange and lung function. This prospective randomized study included 32 patients undergoing elective myocardial revascularization with cardiopulmonary bypass. In 16 patients 5 cm H(2)O of positive end-expiratory pressure was applied after intubation and maintained until extubation (Group I). In the other 16 patients (group II) a positive end expiratory pressure (PEEP) of 5 cm H(2)O was maintained as well but was increased to 14 cm H(2)O every 20 min for 2 min during cross clamp. Measurements were taken preoperatively, before skin incision, before and after (3, 24, 48 h) cardiopulmonary bypass and before discharge (6th postoperative day). Postoperative gas exchange, extravascular lung water and lung function showed no significant difference between the groups. Postoperative pulmonary function variables were lower in both groups compared to baseline values. In patients with normal preoperative pulmonary function, application of an alveolar recruitment strategy during cardiopulmonary bypass does not improve postoperative gas exchange and lung function after cardiac surgery.

    Altered serum proline levels are related to cancer metabolism. This study developed and validated a LC-MS/MS method to analyze proline in human serum. Surrogate blank serum, coupled with stable isotope l-proline-(13) C5 ,(15)  N as internal standard, was used for generating standard curves ranging from 2.5 to 100 μg/mL. Proline was extracted from serum samples using methanol. A Phenomenex Lux 5u Cellulose-1 column (250 × 4.6 mm) was used for chromatographic separation with 40% methanol in 0.05% formic acid aqueous solution as a mobile phase. Mass detection was performed under positive ionization electrospray. Intra- and inter-day accuracy and precision were <10%. The extraction recovery and matrix factor were 99.17 and 1.47%, respectively. Our study showed that the chiral column had high specificity and selectivity for separating proline from serum components. The assay was successfully applied for the quantification of human serum proline levels from 30 esophageal cancer patients and 30 healthy volunteers. Statistical analyses showed significantly lower levels of serum proline in the patients as compared with the healthy volunteers (p-value = 0.011). We report here a simple, specific and reproducible LC-MS/MS method for the quantification of proline in human serum as a potential screening biomarker for esophageal cancer.

    Previous studies have shown that nursing documentation is often deficient in its recording of pain assessment and treatment. In Sweden, documentation of the care process, including assessment, is a legal obligation. The aim of this study was to describe nursing documentation of postoperative pain management and nurses' perceptions of the records in relation to current regulations and guidelines. The sample included nursing records of postoperative care on the second postoperative day from 172 patients and 63 Registered Nurses from surgical wards in a central county hospital in Sweden. The records were reviewed for content and comprehensiveness based on regulations and guidelines for postoperative pain management. Three different auditing instruments were used. The nurses were asked if the documentation concurred with current regulations and guidelines. The result showed that pain assessment was based mainly on patients' self-report, but less than 10% of the records contained notes on systematic assessment with a pain assessment instrument. Pain location was documented in 50% of the records and pain character in 12%. About 73% of the nurses reported that the documentation concurred with current regulations and guidelines. The findings indicate that significant flaws existed in nurses' recording of postoperative pain management, of which the nurses were not aware.

    ABSTRACT Background: The bariatric surgery may cause some nutritional deficiencies. Aim: To compare the serum levels of biochemical markers, in iimmediate post-surgical patients who were submitted to bariatric surgery. Methods: Non-concurrent prospective cross-sectional study. The analysis investigated data in medical charts of pre-surgical and immediate post-surgical patients who were submitted to bariatric surgery, focusing total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C reactive protein, vitamin B12 levels, folic acid, homocysteine values, iron and serum calcium at the referred period. Results: Twenty-nine patients of both genders were evaluated. It was observed weight loss from 108.53 kg to 78.69 kg after the procedure. The variable LDL-c had a significant difference, decreasing approximately 30.3 mg/dl after the surgery. The vitamin B12 serum average levels went from 341.9 pg/ml to 667.2 pg/ml. The triglycerides values were in a range of 129.6 mg/dl-173.3 mg/dl, and 81.9 mg/dl-105.3 mg/dl at the pre- and postoperative respectively. CRP levels fall demonstrated reduction of inflammatory activity. The variable homocysteine was tested in a paired manner and it did not show a significant changing before or after, although it showed a strong correlation with LDL cholesterol. Conclusion: Eligible patients to bariatric surgery frequently present pre-nutritional deficiencies, having increased post-surgical risks when they don´t follow an appropriate nutritional follow-up.

    The postoperative peritonitis (POP) remains formidable conditions due to a high mortality rate of between 20 and 80%. The purpose of this study is to identify risk factors for mortality. This study is a retrospective, descriptive analysis carried out over a period of 09 years (1/1/2003 - 30/11/2011) and interesting 102 patients supported for POP following general surgery. Achieved in department of General Surgery B Charles Nicolle hospital Tunis. The parameters measured included epidemiological data, data related to the Initial Surgical Intervention and reoperation for POP, terms of management and evolution. Bacteriological data were also seized. The incidence of POP was 0.90%. The average age of our patients was 58 +/- 19 years with a sex ratio of 1.08. Forty-seven percent of our patients belonged to the ASAII class. The initial operation was performed urgently in 49 patients (48%) with a majority belonging to the class II Altemeier (49.01%). Colorectal pathology (373%) and hepatobiliay (176%) were the most frequent reasons for the initial intervention. The frequency of clinical signs were fever (75.5%), hypothermia (6.9%), abdominal pain (725%), abdominal distension (46.1%), productive gastric aspiration (30.4%), abdominal defense (25.5%), externalizing the digestive fluid (25.5%), vomiting (19.6%), diarrhea (12.7%), tachycardia (569%), oliguria (42.2%), respiratory failure (40.2%), hypotension (35.3%), neuropsychiatric disorders ( 23.5%) and jaundice (69%). The treatment period was 2.95 +/- 3.16 days. The surgical recovery time was 78 days +/- 5.66. At the time of reoperation, the APACHE II score was 8.43 +/- 6.26 and 25.1 +/- MPI score 8.53. The POP was generalized in 52.9% of cases with purulent peritoneal fluid in 51% of cases. The most common cause was the dropping of the anastomosis (59.8%). Empirical antibiotic therapy was appropriate in 69.44 % of cases. The mortality rate was 39.2%. Multivariate analysis using multiple logistic regression identified the

    Delirium is an acute state of confusion that is often seen in older patients after major orthopedic surgical procedures. It is associated with increased costs of care, morbidity, delayed functional recovery, and prolonged hospital stay. Identification of predictive risk factors, early diagnosis and treatment, and implementation of environmental controls can minimize the impact of postoperative delirium. This project measured pre- and post intervention compliance with best practice in the prevention and management of postoperative delirium.

    Visual laser ablation of the prostate (VLAP) has been shown to be as effective with fewer complications than TURP in the treatment of bladder outlet obstruction secondary to benign prostatic hyperplasia. Questions have been raised about VLAP regarding prolonged irritative and obstructive voiding symptoms postoperatively. It is postulated that these symptoms are due to the slow slough of necrotic debris following VLAP. In an effort to improve upon the technique of VLAP, patients underwent lasing of the prostate in the routine manner (2, 4, 8, and 10 o'clock positions with sixty watts for sixty seconds) using Nd:YAG free beam energy. A bladder neck incision was then performed using a contact laser fiber. International prostate symptom score assessments were done preoperatively; one week and six weeks postoperatively. Post void residual urine volumes and prostate size were also evaluated. The findings indicate that symptom scores and post void residual urine volumes have significantly improved within ten days postoperatively using this technique.

    Induction of anesthesia can be a very stressful period for a child and his family and can be associated with increased risk of psychological disturbances. These disturbances are categorized as preoperative anxiety, emergence delirium and postoperative behavioral changes. Several tools have been developed to measure these psychological manifestations as well as the baseline personality traits of these patients. Postoperative negative behavioral changes, such as sleep and eating disorders, separation anxiety, temper tantrum, aggression toward authorities, may occur in up to 60% of all children undergoing general anesthesia. Several studies found a strong association between these postoperative behavioral changes, the distress of the child on induction and his individual personality characteristics, although a cause-effect relationship could not be determined. Understanding the risk factors for behavior changes helps us determine the best way for prevention and treatment of these changes in the perioperative period.

    Treatment of osteitis after surgical removal of the third molar of the mandible is still a clinical problem. A total of 140 patients undergoing operations for removal of an impacted third molar of the mandible, were included in a double-blind study. Placebo or antibiotics - azidocillin, erythromycin, clindamycin and doxycycline - were given to the patients preoperatively and for the following 7 days. The concentrations in serum, alveolar serum and mandibular bone were measured and the postoperative courses - pain, trismus, swelling and wound-healing - were recorded. No correlation was obtained between the antibiotic concentration and the postoperative complaints, except in the azidocillin group on day 2, in which fewer complaints were noticed in patients with high concentrations of the drug at the time of operations. The 80 patients in the antibiotic groups responded significantly better with respect to wound-healing than the 60 patients in the placebo groups. Only 15 operations lasted more than 15 min and the three of them which subsequently resulted in alveolitis were in the placebo groups. Antibiotics significantly reduced pain on day 7 postoperatively. In general, no statistically significant differences in trismus and swelling could be demonstrated between the patient groups. However, there was a significant difference between the placebo and doxycycline groups with respect to swelling (day 2 postoperative, P < 0.01; day 5 postoperative, P < 0.05). Thus systemically administered antibiotics offered only slight advantages in routine operations of impacted third mandibular molars, but could decrease the rate of infections after traumatic operations.

    Pain is a major postoperative symptom in many oral surgical procedures. It is a complex and variable phenomenon that can be influenced by many factors. Good management of oral surgical pain requires a detailed understanding of the pathogenesis of surgical pain. This article aims at reviewing postoperative pain from a broad perspective by looking into the nociception, neuroanatomy, neurophysiology, and neuropharmacology of pain. Therapeutic recommendations are made after reviewing the evidence from the literature for maximizing the efficacy of pain management techniques for oral surgical pain. PMID:12722900

    Global postoperative amnesia (profound anterograde and retrograde amnesia) is rare and usually attributed to transient global amnesia-a poorly understood condition with no broadly accepted mechanism. We report an incident of probable transient global amnesia in a patient after endoscopic retrograde cholangiopancreatogram under general anesthesia, which was successfully treated with flumazenil. On the basis of the results of flumazenil administration in this and a previous case report, we would recommend a trial dose of 0.2 mg for cases of global postoperative amnesia, repeated if the first dose seems effective.

    Under the effect of acetylsalicyl lysin, a postoperative hypercoagulability was ascertained with regard to shortened antithrombin and partial prothrombin times. The inhibition of aggregation was easily demonstrable with a high concentration of collagen in the test batch and showed a striking relationship to the occurrence of thrombosis. Under heparin prophylaxis, normal coagulability was maintained. Since disorders of hemostasis due to therapy occur sporadically, early postoperative raising of the dose of heparin should only be done under regular laboratory controll, to which activated PTT and antithrombin time is well suited.

    O(6)-methylguanine-DNA methyltransferase (MGMT) promoter methylation is a conventional technique to predict the prognosis or individualized treatment of glioma in tumor tissue following surgery or biopsy. However, the technique cannot be applied in those glioma patients with concomitant neurological dysfunctions or advanced age. The present study aimed to find a new minimally invasive and efficient alternative method for the detection of MGMT promoter methylation. The expression of MGMT promoter methylation was assessed in peripheral blood and cerebrospinal fluid (CSF), and compared to the corresponding tumor tissue from glioma patients. The 89 patients in the study [32 World Health Organization (WHO) grade II, 19 WHO grade III and 38 WHO grade IV) were pathologically-diagnosed glioma and received radiation therapy following sample collection. The resected glioma tumor tissue (89), corresponding serum (89) and CSF (78) samples were collected for the detection of MGMT promoter methylation using methylation-specific polymerase chain reaction. The sensitivity and specificity of detecting MGMT promoter methylation in CSF and serum were compared. Among the tumor tissue samples, 51/89 (57.3%) showed MGMT promoter methylation. The specificity of the detection in the CSF and serum samples reached 100%. The sensitivity of MGMT promoter methylation detection in CSF and serum were 26/40 (65.0%) and 19/51 (37.3%), respectively (P<0.05). In the WHO II, III and IV subgroups, the sensitivities of MGMT promoter methylation detection using CSF were 8/12 (66.7%), 11/18 (61.1%) and 7/10 (70.0%), respectively, which were significantly higher than the sensitivities using serum (7/21, 33.3%; 7/19, 36.8%; and 5/11, 45.5%, respectively P<0.05). Among patients with residual postoperative tumors, the sensitivities of detecting MGMT promoter methylation using CSF and serum were 18/25 (72.0%) and 10/24 (41.7%), respectively, both of which were significantly higher than the corresponding

Sedation scores, visual analog pain scores, cumulative pain scores, serum cortisol concentration, and appetite were used to assess postoperative analgesic effect. Buprenorphine demonstrated the highest efficacy with the lowest cumulative pain scores and serum cortisol levels.

    Background Primary spontaneous pneumothorax (PSP) is a relatively common disorder in young patients. Although various surgical techniques have been introduced, recurrence after video-assisted thoracoscopic surgery (VATS) remains high. The aim of study was to identify the risk factors for postoperative recurrence after thoracoscopic bullectomy in the spontaneous pneumothorax. Methods From January 2011 through March 2013, two hundreds and thirty two patients underwent surgery because of pneumothorax. Patients with a secondary pneumothorax, as well as cases of single port surgery, an open procedure, additional pleural procedure (pleurectomy, pleural abrasion) or lack of medical records were excluded. The records of 147 patients with PSP undergoing 3-port video-assisted thoracoscopic bullectomy with staple line coverage using an absorbable polyglycolic acid (PGA) sheet were retrospectively reviewed. Results The median age was 19 years (range, 11−34 years) with male predominance (87.8%). Median postoperative hospital stay was 3 days (range, 1−10 days) without mortality. Complications were developed in five patients. A total of 24 patients showed postoperative recurrence (16.3%). Younger age less than 17 years old and immediate postoperative air leakage were risk factors for postoperative recurrence after thoracoscopic bullectomy by multivariate analysis. Conclusions Immediate postoperative air leakage was the risk factor for postoperative recurrence. However, further study will be required for the correlation of air leakage with recurrence.

    1Alpha,25-dihydroxyvitamin D3 (1,25-(OH)2D3) is a potent mediator of differentiation and maintenance of specific functions of osteoblasts. To detect novel targets for 1,25-(OH)2D3 action, we applied differential display PCR to human fetal osteoblast-like cells and identified the human analog of murine cystein rich protein 61 (hCYR61) as a 1,25-(OH)2D3-responsive immediate early gene in differentiated fetal osteoblast-like cells. The murine gene CYR61 is important for cell-cell and cell-matrix interactions, and it belongs to an emerging gene family of cysteine-rich proteins. hCYR61 messenger RNA (mRNA) steady-state levels were stimulated 11-fold by 10 nM 1,25-(OH)2D3 by 1 h and declined to control levels by 4 h. This transient stimulation of hCYR61 mRNA was not inhibited by cycloheximide but was prevented by actinomycin D, indicating that the 1,25-(OH)2D3 effect involves transcriptional events and does not require de novo protein synthesis. hCYR61 mRNA stability was not influenced by 1,25(OH)2D3, whereas cycloheximide treatment stabilized hCYR61 mRNA. FCS, as well as growth factors and cytokines such as basic fibroblast growth factor, epidermal growth factor, tumor necrosis factor alpha, and interleukin-1, strongly elevated hCYR61 mRNA steady-state levels within 1 h. hCYR61 mRNA was expressed also in primary human osteoblasts and osteosarcoma cell lines. Using a commercial tissue blot, hCYR61 mRNA was only observed in skeletal muscle. The fast and transient response of hCYR 61 to 1,25-(OH)2D3, serum, growth factors, and cytokines suggests an important role of hCYR61 for osteoblast function and differentiation.

    Objective This study aims to assess the preoperative nutritional status of patients and the role it plays in the occurrence of clinical complications in the postoperative period of major elective cardiac surgeries. Methods Cross-sectional study comprising 72 patients aged 20 years or older, who underwent elective cardiac surgery. The preoperative nutritional assessment consisted of nutritional screening, anthropometry (including the measurement of the adductor pollicis muscle thickness) and biochemical tests. The patients were monitored for up to 10 days after the surgery in order to control the occurrence of postoperative complications. The R software, version 3.0.2, was used to statistically analyze the data. Results Clinical complications were found in 62.5% (n=42) of the studied samples and complications of non-infectious nature were most often found. Serum albumin appeared to be associated with renal complications (P=0.026) in the nutritional status indicators analyzed herein. The adductor pollicis muscle thickness was associated with infectious complications and presented mean of 9.39±2.32 mm in the non-dominant hand (P=0.030). No significant correlation was found between the other indicators and the clinical complications. Conclusion The adductor pollicis muscle thickness and the serum albumin seemed be associated with clinical complications in the postoperative period of cardiac surgeries. PMID:27982346

    Background Preoperative anaemia is associated with adverse outcomes after surgery but outcomes after liver surgery specifically are not well established. We aimed to analyze the incidence of and effects of preoperative anemia on morbidity and mortality in patients undergoing liver resection. Methods All elective hepatectomies performed for the period 2005–2012 recorded in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database were evaluated. We obtained anonymized data for 30-day mortality and major morbidity (one or more major complication), demographics, and preoperative and perioperative risk factors. We used multivariable logistic regression models to assess the adjusted effect of anemia, which was defined as (hematocrit <39% in men, <36% in women), on postoperative outcomes. Results We obtained data for 12,987 patients, of whom 4260 (32.8%) had preoperative anemia. Patients with preoperative anemia experienced higher postoperative major morbidity and mortality rates compared to those without anemia. After adjustment for predefined variables, preoperative anemia was an independent risk factor for postoperative major morbidity (adjusted OR 1.21, 1.09–1.33). After adjustment, there was no significant difference in postoperative mortality for patients with or without preoperative anemia (adjusted OR 0.88, 0.66–1.16). Conclusion Preoperative anemia is independently associated with an increased risk of major morbidity in patients undergoing hepatectomy. Therefore, it is crucial to readdress preoperative blood management in anemic patients prior to hepatectomy. PMID:27017165

    The purpose of this study was to assess the incidence and risk factors associated with postoperative nausea (PON) and vomiting (POV) after orthognathic surgery. A review of the clinical records of consecutively enrolled subjects (2008–2012) at a single academic institution was conducted between 9/2013 and 3/2014. Data on the occurrence of PON and POV and potential patient-related, intraoperative, and postoperative explanatory factors were extracted from the medical records. Logistic models were used for the presence/absence of postoperative nausea and vomiting separately. Data from 204 subjects were analyzed: 63% were female, 72% Caucasian, and the median age was 19 years. Thirty-three percent had a mandibular osteotomy alone, 27% a maxillary osteotomy alone, and 40% had bimaxillary osteotomies. Sixty-seven percent experienced PON and 27% experienced POV. The most important risk factors for PON in this series were female gender, increased intravenous fluids, and the use of nitrous oxide, and for POV were race, additional procedures, and morphine administration. The incidence of PON and POV following orthognathic surgery in the current cohort of patients, after the introduction of the updated 2007 consensus guidelines for the management of postoperative nausea and vomiting, has not decreased substantially from that reported in 2003–2004.

    Fractures of the proximal femur are frequently seen in elderly people and will increase due to the demographic development of most industrialized countries. Early operation of dislocated fractures with either osteosynthesis or hemiprothesis has become a standard treatment for this type of injury. The high co-morbidity often leads to secondary complications like infections still resulting in a perioperative mortality rate of 11%. The perioperative infusion regime might influence the postoperative inflammatory response. Therefore Biseko(®), a serum protein solution, was compared to albumin and crystalloid infusion (Elomel). A total of 45 patients with proximal femur fractures were randomly assigned to either of the groups and received 500 ml of the infusion on 3 days starting from the day of operation. The Biseko(®) group showed significantly lower CRP levels, less infections and antibiotic treatment as well as a better clinical outcome referring to the TISS28 and APACHE Score. Concerning IL-6, IL-8, IL-10 and serum leukocytes no significant differences were observed. The result shows a beneficial influence of the serum protein solution Biseko(®) concerning the number of perioperative complications. The design of this study and the small number of patients does not yet allow any conclusion concerning the effectiveness of this treatment.

    The postoperative growth rates achieved in eight early pubertal adolescent males with Crohn's disease undergoing surgery for obstructive complications is reported as a function of the use of 1 month's preoperative central venous alimentation. All patients had ileal strictures with ileocolitis, bone ages less than 13, Tanner stages 1 or 2, and growth velocities below the 3rd percentile for age. During a 3-year follow-up, those receiving preoperative venous alimentation demonstrated greater oral caloric intake (significant for 1 year) and greater postoperative growth velocity (significant for 2 years) in comparison to those patients who did not receive preoperative venous alimentation. There was no significant difference between the two groups of patients in postoperative weight gain, sexual development, and 3-year disease control.

    AIM To investigate the association between postoperative pain control and oncologic outcomes in resected pancreatic ductal adenocarcinoma (PDAC). METHODS From January 2009 to December 2014, 221 patients were diagnosed with PDAC and underwent resection with curative intent. Retrospective review of the patients was performed based on electronic medical records system. One patient without records of numerical rating scale (NRS) pain intensity scores was excluded and eight patients who underwent total pancreatectomy were also excluded. NRS scores during 7 postoperative days following resection of PDAC were reviewed along with clinicopathologic characteristics. Patients were stratified into a good pain control group and a poor pain control group according to the difference in average pain intensity between the early (POD 1, 2, 3) and late (POD 5, 7) postoperative periods. Cox-proportional hazards multivariate analysis was performed to determine association between postoperative pain control and oncologic outcomes. RESULTS A total of 212 patients were dichotomized into good pain control group (n = 162) and poor pain control group (n = 66). Median follow-up period was 17 mo. A negative impact of poor postoperative pain control on overall survival (OS) was observed in the group of patients receiving distal pancreatectomy (DP group; 42.0 mo vs 5.0 mo, P = 0.001). Poor postoperative pain control was also associated with poor disease-free survival (DFS) in the DP group (18.0 mo vs 8.0 mo, P = 0.001). Patients undergoing pancreaticoduodenectomy or pylorus-preserving pancreaticoduodenectomy (PD group) did not show associations between postoperative pain control and oncologic outcomes. Poor patients’ perceived pain control was revealed as an independent risk factor of both DFS (HR = 4.157; 95%CI: 1.938-8.915; P < 0.001) and OS (HR = 4.741; 95%CI: 2.214-10.153; P < 0.001) in resected left-sided pancreatic cancer. CONCLUSION Adequate postoperative pain relief during the early

    Abstract The aim of this study was to explore the impact of 3% hypertonic saline (HS) intragastric administration for patients who underwent upper gastrointestinal surgery. During the postoperative period, 3% HS has been suggested as a means to improve the intestinal edema and reduce gastrointestinal complications. The medical records of 111 patients with HS intragastric administration following upper gastrointestinal surgery and 268 patients, served as control, were reviewed retrospectively. Propensity score matching was performed to adjust for selected baseline variables. Clinical outcomes, including early gastrointestinal function recovery, postoperative complications, and length of hospital stay, were compared according to the HS intragastric administration or not. HS intragastric administration was associated with prompt postoperative gastrointestinal function recovery, including first flatus (risk ratio [RR], 1.32; 95% confidence interval [CI], 0.89–1.65; P = 0.048) and feeding within 3 postoperative days (RR (95% CI), 0.57 (0.49–0.77); P = 0.036). Early ileus occurred in 25 of 108 patients with HS treatment versus 36 of 108 patients without HS treatment (RR (95% CI), 1.43 (0.63–2.15); P = 0.065). The patients with HS experienced a lower overall postoperative complication (odds ratio [OD] 0.57; 95% CI, 0.33–1.09; P = 0.063), including trend toward a decrease for infectious complications (15[13.9] vs 23[21.3]; P = 0.11; OD, 0.59; 95% CI, 0.29–1.22). There was a decreased incidence of anastomotic leakage (1[0.9] vs 7[6.5]; P = 0.033) and postoperative ileuas (5[4.6%] vs 11[10.2%]; P = 0.096) in the HS administration patients. Our study demonstrated beneficial postoperative clinical effects of HS intragastric administration in patients who had undergone upper gastrointestinal surgery, such as prompt postoperative gastrointestinal function recovery and reduced overall postoperative complications, which may be attributed to a

    Kidneys procured by donation after cardiac death (DCD) may increase the donor pool but are associated with high incidence of delayed graft function (DGF). Urinary liver-type fatty acid-binding protein (L-FABP) level is an early biomarker of renal injury after kidney transplantation (KTx); however, its utility is limited in DGF cases owing to urine sample unavailability. We examined whether serum L-FABP level predicts functional recovery of transplanted DCD kidneys. Consecutive patients undergoing KTx from living related donors (LD), brain-dead donors (BD), or DCD were retrospectively enrolled. Serum L-FABP levels were measured from samples collected before and after KTx. Serum L-FABP decreased rapidly in patients with immediate function, slowly in DGF patients, and somewhat increased in DGF patients requiring hemodialysis (HD) for >1 wk. Receiver-operating characteristic curve analysis demonstrated that DGF was predicted with 84% sensitivity (SE) and 86% specificity (SP) at cutoff of 9.0 ng/mL on post-operative day (POD) 1 and 68% SE and 90% SP at 6.0 on POD 2. DGF >7 d was predicted with 83% SE and 78% SP at 11.0 on POD 1 and 67% SE and 78% SP at 6.5 on POD 2. Serum L-FABP levels may predict graft recovery and need for HD after DCD KTx.

    The purpose of this case-control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status. All 34 consecutive patients undergoing hybrid minimally invasive esophagectomy for cancer at our surgical unit between 2008 and 2013 were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization (open), matched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course (including quality of life and systemic inflammatory and nutritional status) were compared. Postoperative course was similar in terms of complication rate. Length of stay in intensive care unit was shorter in patients undergoing hybrid minimally invasive esophagectomy (P = 0.002). In the first postoperative day, patients undergoing hybrid minimally invasive esophagectomy had lower C-reactive protein levels (P = 0.001) and white cell blood count (P = 0.05), and higher albumin serum level (P = 0.001). In this group, albumin remained higher also at third (P = 0.06) and seventh (P = 0.008) postoperative day, and C-reactive protein resulted lower at third post day (P = 0.04). Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit.

    With the increasing longevity of the population, the annual rates of hip arthroplasties performed have been steadily increasing over the past decade. Given the presence of medical comorbidities in the older patients, the peri-operative care of these individuals requires multi-specialty care, now more than ever. Hip arthroplasty is generally well tolerated, with early mortality after the procedure being <1%. Bone cement implantation syndrome (BCIS) is an entity that is occasionally encountered during or after the surgery. It is characterized by hypoxemia, hypotension, cardiac arrhythmias, and cardiac arrest leading to death, in severe cases. We report a case of a middle-aged female who developed refractory hypotension and pulmonary edema while undergoing hemiarthroplasty for a pathological femoral neck fracture and experienced cardiac arrest in the immediate postoperative period. Critical care physicians must familiarize themselves with promptly diagnosing and managing BCIS. PMID:28250610

    Low cardiac output syndrome frequently complicates the post-operative care of infants and children following cardiac surgery. The onset of low cardiac output follows a predictable course in the hours following cardiopulmonary bypass, as myocardial performance declines in the face of an elevated demand for cardiac output. When demand outstrips supply, shock ensues, and early recognition and intervention can decrease mortality. Multifactorial in etiology, this article will discuss the pathophysiology of low cardiac output syndrome, including myocardial depression following bypass, altered cardiac loading conditions, and inflammation driving a hypermetabolic state. Contributions from altered neurohormonal, thyroid, and adrenal axes will also be discussed. Sources included the clinical experiences of four cardiac intensivists, supported throughout by primary sources and relevant reviews obtained through PubMed searches and from seminal textbooks in the field. This article addresses the second of eight topics comprising the special issue entitled "Pharmacologic strategies with afterload reduction in low cardiac output syndrome after pediatric cardiac surgery".

    A four-year-old girl suffered difficult-to-diagnose hyponatremia resistant to treatment following surgery for a suprasellar tumor. The final diagnosis was diabetes insipidus evolving in three stages. Hyponatremia is a common problem following surgery to remove brain tumors. Early diagnosis and treatment of this electrolytic imbalance are essential for preventing serious neurological symptoms or death. The conditions most closely related to hyponatremia are inappropriate antidiuretic hormone secretion syndrome (IADHSS) and cerebral salt wasting syndrome (CSWS). The latter has become more common in recent years among patients undergoing brain surgery. Whereas IADHSS is treated by restricting fluids, CSWS requires administration of salt and volume fluid volume. We believe that for differential diagnosis of postoperative hyponatremia, a fluid restriction test takes priority over of fluid loading following neurosurgery. The course of hyponatremia must be carefully monitored and a complete endocrinological workup must be performed to detect the possible presence of hypophyseal deficiencies, particularly hypothyroidism and suprarenal insufficiency.

    The correct application of multimodal analgesia appropriate to the pain intensity, the characteristics of the surgery and the hospitalisation scheme provide the key to improving the management of postoperative pain, which is currently still under treated. In highly complex surgeries the best benefit is obtained by combining systemic analgesic drugs with regional analgesia techniques. Epidural analgesia, not only provides an excellent quality of analgesia, but can prevent complications and reduce postoperative morbidity. Recently, peripheral blocks and parietal infiltration techniques, with or without catheter, have gained prominence in the postoperative analgesia of haemorrhoids and hernia repair. All these analgesic techniques are integrated into the concept of early postoperative rehabilitation and pursue the objective of minimising the side effects associated with the treatment and facilitate the functional recovery of the patient. In addition, proper postoperative pain management, not only increases the quality of in-patient care but is also a factor to consider in the development of chronic post-surgical pain, where the impact is significant and impairs the quality of life of the patients.

    Orthotopic liver transplantation (OLT) is the only definitive treatment for irreversible acute liver failure and chronic liver disease. In the immediate postoperative period after OLT, patients are closely monitored with Doppler ultrasonography (US) to detect treatable vascular complications and ensure graft survival. The first postoperative Doppler US examination is performed fairly early on the first postoperative day, before surgical wound closure has been performed. The immediate postoperative images, obtained when the effects of surgery are very recent, often reveal an array of findings that may appear alarming but that tend to normalize within a few days and are compatible with changes related to the surgery itself. These findings include a starry-sky appearance of reperfusion hepatic edema, transient foci of increased echogenicity, pneumobilia, small fluid collections, perihepatic hematomas, pleural effusion, temporary elevation of hepatic arterial velocity, transient elevation of resistive index (RI), decreased RI with tardus parvus waveform, increased portal venous flow and mono- or biphasic waveforms of the hepatic veins. Most of these changes revert to normal in the first postoperative week; deterioration atypical of transient changes requires further evaluation.

    Background This is an updated version of the original Cochrane review published in Issue 2, 2000. Dihydrocodeine is a synthetic opioid analgesic developed in the early 1900s. Its structure and pharmacokinetics are similar to that of codeine and it is used for the treatment of postoperative pain or as an antitussive. It is becoming increasingly important to assess the relative efficacy and harm caused by different treatments. Relative efficacy can be determined when an analgesic is compared with control under similar clinical circumstances. Objectives To quantitatively assess the analgesic efficacy and adverse effects of single-dose dihydrocodeine compared with placebo in randomised trials in moderate to severe postoperative pain. Search methods Published reports were identified from electronic databases (MEDLINE, EMBASE, CENTRAL, the Oxford Pain Relief Database in December 2007, the original search was conducted in October 1999). Additional studies were identified from the reference lists of retrieved reports. Selection criteria Inclusion criteria: full journal publication, clinical trial, random allocation of participants to treatment groups, double blind design, adult participants, baseline pain of moderate to severe intensity, postoperative administration of study drugs, treatment arms which included dihydrocodeine and placebo and either oral or injected (intramuscular or intravenous) administration of study drugs. Data collection and analysis Data collection and analysis: summed pain intensity and pain relief data over four to six hours were extracted and converted into dichotomous information to yield the number of participants obtaining at least 50% pain relief. This was used to calculate relative benefit and number-needed-to-treat-to-benefit (NNT) for one participant to obtain at least 50% pain relief. Single-dose adverse effect data were collected and used to calculate relative risk and number-needed-to-treat-to-harm (NNH). Main results Fifty-two reports

    Background and Aims: Postoperative patient evaluation is an integral component of perioperative care. An audit of our anesthesia department's records demonstrated a compliance rate of <50%. We postulated that the development of clinical anesthesia service dedicated to performing such evaluations would improve compliance significantly. Materials and Methods: This retrospective study examined postoperative follow-up completion rate at a large academic center. Data were collected from 58,000 anesthetics during three periods, between each of which an intervention was introduced. The first period examined completion rate when postoperative evaluations were left to the team performing the anesthetic. During the second period, this task was delegated to groups of anesthesiologists based on surgical subspecialty; these smaller groups utilized rotating residents. The third period examined completion rate after implementation of a postoperative evaluation service. All periods utilized the department's electronics database to identify operative patients. The number of adverse anesthesia events reported was also recorded. Results: A significant difference in the proportions of compliance with postoperative evaluations among all three periods was detected. Compliance was 47% during period one and improved to 66% during period two. During period three, which employed a postoperative evaluation service, compliance was 83%. The number of adverse events reported per month increased significantly following the first study period from 95 reported monthly events to 215 and 201 in the second and third periods, respectively. Conclusion: By creating a dedicated postoperative evaluation service using available technology, we improved postoperative evaluation completion rate from 47% to 83%, and demonstrated a significant increase in the number of adverse events reported. Based on this, we support the deployment of a dedicated service as a quality improvement initiative. PMID:25788778

    In recent years idiopathic macular hole has become an increasingly frequent indication for vitrectomy. To our knowledge, the literature contains no studies comparing binocular vision before and after vitrectomy. We therefore carried out a prospective study not only on visual acuity following vitrectomy but also, for the first time, on binocular vision. Stereopsis and fusion were evaluated in 37 patients with idiopathic macular holes (stage I-IV) using Bagolini striated glasses, the Titmus stereotest (contour stereopsis), the random dot test (global stereopsis), the Worth four-dot test and the phase-difference haploscope. The tests were performed preoperatively and 10-12 weeks after vitrectomy. Two patients with stage I macular hole showed no loss of stereopsis in conventional tests. One patient, however, exhibited suppression tendencies with partial exclusion. The 18 patients with stage II macular hole had a relative good visual acuity of 0.2-0.6, but subnormal binocular vision with marked suppression of foveal images. Postoperatively, the majority of these patients had symptom-free binocular vision and good stereopsis. Some, however, continued to experience foveal exclusion. Patients with macular hole stage III and IV (n = 17) had the poorest results. Although the postoperative visual acuity improved by 2 to 3 points in some patients (n = 6), in approximately one third it remained limited to global peripheral binocular vision. In summary, our findings show that even in early stages (I and II), macular hole can cause not only reduced visual acuity but also impairment or, in stage II, even loss of binocular vision. Vitrectomy in these early stages often leads to an overall improvement in visual acuity and binocular vision, whereas in more advanced stages vitrectomy often does not affect visual acuity and binocular vision. This should be taken into account when weighing up the indications for surgery.

    Background Axillary web syndrome (AWS) is a condition that may develop following breast cancer surgery and that presents as a palpable axillary cord of tissue. Objective The purposes of this study were: (1) to determine the clinical characteristics of AWS related to movement, function, pain, and postoperative edema and (2) to define the incidence of and risk factors for AWS within the first 3 months following breast cancer surgery. Design This was a prospective cohort study with a repeated-measures design. Methods Women who underwent breast cancer surgery with sentinel node biopsy or axillary lymph node dissection (N=36) were assessed for AWS, shoulder range of motion, function, pain, and postoperative edema (using girth measurements, bioimpedance, and tissue dielectric constant) at 2, 4, and 12 weeks. Demographic characteristics were used for risk analysis. Results Seventeen women (47.2%) developed AWS, and AWS persisted in 10 participants (27.8%) at 12 weeks. Abduction range of motion was significantly lower in the AWS group compared with the non-AWS group at 2 and 4 weeks. There were no differences between groups in measurements of function, pain, or edema at any time point. Trunk edema measured by dielectric constant was present in both groups, with an incidence of 55%. Multivariate analysis determined lower body mass index as being significantly associated with AWS (odds ratio=0.86; 95% confidence interval=0.74, 1.00). Limitations Limitations included a short follow-up time and a small sample size. Conclusion Axillary web syndrome is prevalent following breast/axilla surgery for early-stage breast cancer and may persist beyond 12 weeks. The early consequences include movement restriction, but the long-term effects of persistent AWS cords are yet unknown. Low body mass index is considered a risk factor for AWS. PMID:25977305

    A 62-year-old man with no major comorbidities became acutely hyponatraemic on the second postoperative day following a routine carotid endarterectomy. He developed a headache, became hypertensive and confused, and then had a seizure and required intubation and admission to the intensive care unit. A CT angiogram of his head and carotid arteries was normal, as was a subsequent MRI head. His serum and urine osmolality were low. He was treated by fluid restriction and his hyponatraemia resolved over 3 days. On discontinuation of sedation the patient woke up appropriately. The cause of his hyponatraemia was initially a mystery but when questioned by the medical team he admitted that he drank about 5 litres of water in the afternoon on the second postoperative day. At this point the diagnosis of dilutional hypervolaemic hyponatraemia secondary to water intoxication could be made.

    This article aims to identify risk factors for postoperative pancreatic fistula (POPF) and evaluate the gastric/pancreatic amylase ratio (GPAR) on postoperative day (POD) 3 as a POPF predictor in patients who undergo pancreaticoduodenectomy (PD).POPF significantly contributes to mortality and morbidity in patients who undergo PD. Previously identified predictors for POPF often have low predictive accuracy. Therefore, accurate POPF predictors are needed.In this prospective cohort study, we measured the clinical and biochemical factors of 61 patients who underwent PD and diagnosed POPF according to the definition of the International Study Group of Pancreatic Fistula. We analyzed the association between POPF and various factors, identified POPF risk factors, and evaluated the predictive power of the GPAR on POD3 and the levels of serum and ascites amylase.Of the 61 patients, 21 developed POPF. The color of the pancreatic drain fluid, POD1 serum, POD1 median output of pancreatic drain fluid volume, and GPAR were significantly associated with POPF. The color of the pancreatic drain fluid and high GPAR were independent risk factors. Although serum and ascites amylase did not predict POPF accurately, the cutoff value was 1.24, and GPAR predicted POPF with high sensitivity and specificity.This is the first report demonstrating that high GPAR on POD3 is a risk factor for POPF and showing that GPAR is a more accurate predictor of POPF than the previously reported amylase markers.

    Introduction. Few data are available on vitamin A deficiency in the gastric bypass population. Methods. We performed a retrospective chart review of gastric bypass patients (n = 69, 74% female). The relationship between serum vitamin A concentration and markers of protein metabolism at 6-weeks and 1-year post-operative were assessed. Results. The average weight loss at 6-weeks and 1-year following surgery was 20.1 ± 9.1 kg and 44.1 ± 17.1 kg, respectively. At 6 weeks and 1 year after surgery, 35% and 18% of patients were vitamin A deficient, (<325 mcg/L). Similarly, 34% and 19% had low pre-albumin levels (<18 mg/dL), at these time intervals. Vitamin A directly correlated with pre-albumin levels at 6 weeks (r = 0.67, P < 0.001) and 1-year (r = 0.67,  P < 0.0001). There was no correlation between the roux limb length measurement and pre-albumin or vitamin A serum concentrations at these post-operative follow-ups. Vitamin A levels and markers of liver function testing were also unrelated. Conclusion. Vitamin A deficiency is common after bariatric surgery and is associated with a low serum concentration of pre-albumin. This fat-soluble vitamin should be measured in patients who have undergone gastric bypass surgery and deficiency should be suspected in those with evidence of protein-calorie malnutrition.

    Monoclonal antibodies are used to detect serum antigens associated with specific malignancies. These tumor markers are most useful for monitoring response to therapy and detecting early relapse. With the exception of prostate-specific antigen (PSA), tumor markers do not have sufficient sensitivity or specificity for use in screening. Cancer antigen (CA) 27.29 most frequently is used to follow response to therapy in patients with metastatic breast cancer. Carcinoembryonic antigen is used to detect relapse of colorectal cancer, and CA 19-9 may be helpful in establishing the nature of pancreatic masses. CA 125 is useful for evaluating pelvic masses in postmenopausal women, monitoring response to therapy in women with ovarian cancer, and detecting recurrence of this malignancy. Alpha-fetoprotein (AFP), a marker for hepatocellular carcinoma, sometimes is used to screen highly selected populations and to assess hepatic masses in patients at particular risk for developing hepatic malignancy. Testing for the beta subunit of human chorionic gonadotropin (beta-hCG) is an integral part of the diagnosis and management of gestational trophoblastic disease. Combined AFP and beta-hCG testing is an essential adjunct in the evaluation and treatment of nonseminomatous germ cell tumors, and in monitoring the response to therapy. AFP and beta-hCG also may be useful in evaluating potential origins of poorly differentiated metastatic cancer. PSA is used to screen for prostate cancer, detect recurrence of the malignancy, and evaluate specific syndromes of adenocarcinoma of unknown primary.

    IMPORTANCE Postoperative hypocalcemia is common after total thyroidectomy, and perioperative monitoring of serum calcium levels is arguably the primary reason for overnight hospitalization. Confidently predicting which patients will not develop significant hypocalcemia may allow for a safe earlier discharge. OBJECTIVE To examine associations of patient characteristics with hypocalcemia, duration of hospitalization, and postoperative intact parathyroid hormone (IPTH) level after total thyroidectomy. DESIGN, SETTING, AND PARTICIPANTS Retrospective study of consecutive patients who underwent total thyroidectomy by a single high-volume surgeon between February 1, 2010, and November 30, 2012. Postoperative serum 25-hydroxyvitamin D (vitamin D), calcium, and IPTH levels were tested within 6 to 8 hours after surgery. Mild hypocalcemia was defined as any postoperative serum calcium level of less than 8.4 to 8.0 mg/dL. Significant hypocalcemia was defined as any postoperative serum calcium level of less than 8.0 mg/dL or the development of hypocalcemia-related symptoms. INTERVENTIONS Total thyroidectomy. MAIN OUTCOMES AND MEASURES Associations of patient demographic and clinical characteristics and laboratory values with postoperative mild and significant hypocalcemia were examined using univariate analysis, and independent predictors of hypocalcemia, duration of hospitalization, and IPTH level were determined using multivariate analysis. RESULTS Overall, 304 total thyroidectomies were performed. Mild and significant hypocalcemia occurred in 68 (22.4%) and 91 (29.9%) patients, respectively, of which the majority were female (P = .003). The development of significant hypocalcemia was associated with postoperative IPTH level (P < .001). On multivariate analysis, males had a decreased risk of developing mild (odds ratio, 0.37 [95% CI, 0.16–0.85]) and significant (odds ratio, 0.57 [95% CI, 0.09–0.78]) hypocalcemia.

    The optimal anesthetic technique for peripheral vascular surgery remains controversial. The purpose of this study was to evaluate the effect of spinal versus general anesthesia on postoperative pain, analgesic requirements and postoperative comfort in patients undergoing peripheral vascular surgery. A total of 40 patients scheduled for peripheral vascular surgery were randomly assigned to two groups of 20 patients each to receive general anesthesia (GA) or spinal anesthesia (SA). In GA group, anesthesia was induced using thiopental and fentanyl. Vecuronium was used for muscle relaxation. Anaesthesia was maintained with isoflurane and nitrous oxide. In the SA group, hyperbaric 0.5% bupivacaine was injected into the subarachnoid space. Postoperative pain was assessed for 24 hours by a visual analog scale during three assessment periods: 0-4, 4-12 and 12-24 h as well as analgesic requirements. Patients were also asked to assess their postoperative state as satisfactory or unsatisfactory with regard to the pain, side effects and postoperative nausea and vomiting. Visual analogue scale (VAS) pain score was significantly lower in the group SA compared with group GA. This effect was mainly due to the lower pain score during the first study period. The patients received general anesthesia also reported a significantly higher rate of unsatisfactory postoperative comfort than those receiving spinal anesthesia. We conclude that spinal anesthesia is superior to general anesthesia when considering patients' satisfaction, side effects and early postoperative analgesic management.

    Pain is a predictable consequence following operations, but the management of postoperative pain is another challenge for anesthesiologists and inappropriately controlled pain may lead to unwanted outcomes in the postoperative period. Opioids are indeed still at the mainstream of postoperative pain control, but solely using only opioids for postoperative pain management may be connected with risks of complications and adverse effects. As a consequence, the concept of multimodal analgesia has been proposed and is recommended whenever possible. Acetaminophen is one of the most commonly used analgesic and antipyretic drug for its good tolerance and high safety profiles. The introduction of intravenous form of acetaminophen has led to a wider flexibility of its use during peri- and postoperative periods, allowing the early initiation of multimodal analgesia. Many studies have revealed the efficacy, safety and opioid sparing effects of intravenous acetaminophen. Intravenous ibuprofen has also shown to be well tolerated and demonstrated to have significant opioid sparing effects during the postoperative period. However, the number of randomized controlled trials confirming the efficacy and safety is small and should be used in caution in certain group of patients. Intravenous acetaminophen and ibuprofen are important options for multimodal postoperative analgesia, improving pain and patient satisfaction. PMID:25664148

    2016-01-01

    Living-donor liver transplantation has provided a solution to the severe lack of cadaver grafts for the replacement of liver afflicted with end-stage cirrhosis, fulminant disease, or inborn errors of metabolism. Vascular complications remain the most serious complications and a common cause for graft failure after hepatic transplantation. Doppler ultrasound remains the primary radiological imaging modality for the diagnosis of such complications. This article presents a brief review of intra- and post-operative living donor liver transplantation anatomy and a synopsis of the role of ultrasonography and color Doppler in evaluating the graft vascular haemodynamics both during surgery and post-operatively in accurately defining the early vascular complications. Intra-operative ultrasonography of the liver graft provides the surgeon with useful real-time diagnostic and staging information that may result in an alteration in the planned surgical approach and corrections of surgical complications during the procedure of vascular anastomoses. The relevant intra-operative anatomy and the spectrum of normal and abnormal findings are described. Ultrasonography and color Doppler also provides the clinicians and surgeons early post-operative potential developmental complications that may occur during hospital stay. Early detection and thus early problem solving can make the difference between graft survival and failure. PMID:27468207

    The records of 70 patients with oral cancer who were treated at a single institution between 2008 and 2014 were reviewed. The body temperature, white blood cell count, and C-reactive protein (CRP) levels were compared between those who had received preoperative oral care (oral care group) and those who had not received any (non-oral care group). When the patients were divided into those who underwent minimally invasive surgery and those who underwent severely invasive surgery, the mean CRP level in the early postoperative period was lower in the oral care group as compared with the non-oral care group in those who underwent minimally invasive surgery as well as those who underwent severely invasive surgery. However, the mean CRP level was most evidently reduced in the severely invasive group on days 1 and 3–5. However, no significant differences were observed with regard to the percentage of postoperative infectious complications (for example, surgical site infection, anastomotic leak and pneumonia) between the oral care (13.6%) and non-oral care (20.8%) groups, though a reduced prevalence of postoperative complications following preoperative oral care was noted. The results of the present study suggest that preoperative oral care can decrease inflammation during the early postoperative stage in patients with oral cancer who undergo severely invasive surgery.

    Background. Parasternal block and transcutaneous electrical nerve stimulation (TENS) have been demonstrated to produce effective analgesia and reduce postoperative opioid requirements in patients undergoing cardiac surgery. Objectives. To compare the effectiveness of TENS and parasternal block on early postoperative pain after cardiac surgery. Methods. One hundred twenty patients undergoing cardiac surgery were enrolled in the present randomized, controlled prospective study. Patients were assigned to three treatment groups: parasternal block, intermittent TENS application, or a control group. Results. Pain scores recorded 4 h, 5 h, 6 h, 7 h, and 8 h postoperatively were lower in the parasternal block group than in the TENS and control groups. Total morphine consumption was also lower in the parasternal block group than in the TENS and control groups. It was also significantly lower in the TENS group than in the control group. There were no statistical differences among the groups regarding the extubation time, rescue analgesic medication, length of intensive care unit stay, or length of hospital stay. Conclusions. Parasternal block was more effective than TENS in the management of early postoperative pain and the reduction of opioid requirements in patients who underwent cardiac surgery through median sternotomy.

    One hundred thirty five patients with osteoarthritis who underwent total knee arthroplasty (TKA) were evaluated to determine whether specific pre- and postoperative variables were correlated with the postoperative range of motion. Age, sex, pre- and postoperative range of motion, pre- and postoperative Knee Society scores, intraoperative patellar thickness before and after resurfacing, pre- and postoperative radiographic patellar height (as determined by the Insall-Salvati and Blackburn-Peel ratios), and preoperative radiographic alignment were recorded for each patient. Regression analysis was performed to identify whether any variables were correlated with the postoperative range of motion or Knee Society scores. The only variable that was significantly correlated with postoperative range of motion was the preoperative range of motion. This study suggests that among the variables evaluated, the preoperative range of motion was the only significant predictor of postoperative range of motion.

  11. Piezoelectric microcantilever serum protein detector

    NASA Astrophysics Data System (ADS)

    Capobianco, Joseph A.

    The development of a serum protein detector will provide opportunities for better screening of at-risk cancer patients, tighter surveillance of disease recurrence and better monitoring of treatment. An integrated system that can process clinical samples for a number of different types of biomarkers would be a useful tool in the early detection of cancer. Also, screening biomarkers such as antibodies in serum would provide clinicians with information regarding the patient's response to treatment. Therefore, the goal of this study is to develop a sensor which can be used for rapid, all-electrical, real-time, label-fee, in-situ, specific quantification of cancer markers, e.g., human epidermal receptor 2 (Her2) or antibodies, in serum. To achieve this end, piezoelectric microcantilever sensors (PEMS) were constructed using an 8 mum thick lead magnesium niobate-lead titanate (PMN-PT) freestanding film as the piezoelectric layer. The desired limit of detection is on the order of pg/mL. In order to achieve this goal the higher frequency lateral extension modes were used. Also, as the driving and sensing of the PEMS is electrical, the PEMS must be insulated in a manner that allows it to function in aqueous solutions. The insulation layer must also be compatible with standardized bioconjugation techniques. Finally, detection of both cancer antigens and antibodies in serum was carried out, and the results were compared to a standard commercialized protocol. PEMS have demonstrated the capability of detecting Her2 at a concentration of 5 pg/mL in diluted human serum (1:40) in less than 1 hour. The approach can be easily translated into the clinical setting because the sensitivity is more than sufficient for monitoring prognosis of breast cancer patients. In addition to Her2 detection, antibodies in serum were assayed in order to demonstrate the feasibility of monitoring the immune response for antibody-dependent cellular cytotoxicity (ADCC) in patients on antibody therapies

    We report a series of 15 patients with a postoperative biliary fistula treated by endoscopic sphincterotomy. The exact location of the bile leak was revealed by ERCP in 13 cases (87%): cystic duct remnant in 6 (39%), intrahepatic biliary tree in 4 (26%), and main bile duct in 3 (20%). In all cases a distal obstacle (ie: retained stones, hydatid material) to bile flow was also found in ERCP. Treatment consisted of endoscopic sphincterotomy and subsequent removal of the distal obstacle, and could be completed in 13 (87%) cases. In our experience the treatment of postoperative biliary fistula with a distal obstruction bile flow by endoscopic sphincterotomy is a safe and effective procedure, and should be recommended as the first option in those patients.

    Pulmonary complications are a major cause of morbidity and mortality in the post-operative period after thoracotomy. The type of complications and the severity of complications depend on the type of thoracic surgery that has been performed as well as on the patient's pre-operative medical status. Risk stratification can help in predicting the possibility of the post-operative complications. Certain airway complications are more prone to develop with thoracic surgery. Vocal cord injuries, bronchopleural fistulae, pulmonary emboli and post-thoracic surgery non-cardiogenic pulmonary oedema are some of the unique complications that occur in this subset of patients. The major pulmonary complications such as atelectasis, bronchospasm and pneumonia can lead to respiratory failure. This review was compiled after a search for search terms within ‘post-operative pulmonary complications after thoracic surgery and thoracotomy’ on search engines including PubMed and standard text references on the subject from 2000 to 2015.

    Post-operative complications have a significant impact on patient morbidity and mortality; these impacts are exacerbated when patients experience multiple complications. However, the task of modeling the temporal sequencing of complications has not been previously addressed. We present an approach based on Markov chain models for characterizing the temporal evolution of post-operative complications represented in the American College of Surgeons National Surgery Quality Improvement Program database. Our work demonstrates that the models have significant predictive value. In particular, an inhomogenous Markov chain model effectively predicts the development of serious complications (coma longer than a day, cardiac arrest, myocardial infarction, septic shock, renal failure, pneumonia) and interventional complications (unplanned re-intubation, longer than 2 days on a ventilator and bleeding transfusion).

    Postoperative pelvic pain after gynecological surgery is a readily detected but unspecific sign of complication. Imaging as a complement to physical examination helps establish the etiological diagnosis. In the context of emergency surgery, vascular, urinary and digestive injuries constitute the most frequent intraoperative complications. During the follow-up of patients who had undergone pelvic surgery, imaging should be performed to detect recurrent disease, postoperative fibrosis, adhesions and more specific complications related to prosthetic material. Current guidelines recommend using pelvic ultrasonography as the first line imaging modality whereas the use of pelvic computed tomography and/or magnetic resonance imaging should be restricted to specific situations, depending on local availability of equipment and suspected disease.

    Background: Postoperative rehabilitation after arthroscopic rotator cuff repair (ARCR) remains controversial and suffers from limited high-quality evidence. Therefore, appropriate use criteria must partially depend on expert opinion. Hypothesis/Purpose: The purpose of the study was to determine and report on the standard and modified rehabilitation protocols after ARCR used by member orthopaedic surgeons of the American Orthopaedic Society for Sports Medicine (AOSSM) and the Arthroscopy Association of North America (AANA). We hypothesized that there will exist a high degree of variability among rehabilitation protocols. We also predict that surgeons will be prescribing accelerated rehabilitation. Study Design: Cross-sectional study; Level of evidence, 4. Methods: A 29-question survey in English language was sent to all 3106 associate and active members of the AOSSM and the AANA. The questionnaire consisted of 4 categories: standard postoperative protocol, modification to postoperative rehabilitation, operative technique, and surgeon demographic data. Via email, the survey was sent on September 4, 2013. Results: The average response rate per question was 22.7%, representing an average of 704 total responses per question. The most common immobilization device was an abduction pillow sling with the arm in neutral or slight internal rotation (70%). Surgeons tended toward later unrestricted passive shoulder range of motion at 6 to 7 weeks (35%). Strengthening exercises were most commonly prescribed between 6 weeks and 3 months (56%). Unrestricted return to activities was most commonly allowed at 5 to 6 months. The majority of the respondents agreed that they would change their protocol based on differences expressed in this survey. Conclusion: There is tremendous variability in postoperative rehabilitation protocols after ARCR. Five of 10 questions regarding standard rehabilitation reached a consensus statement. Contrary to our hypothesis, there was a trend toward later

    Occasionally radiation is required as adjunctive therapy following mastectomy for breast cancer. The effects of radiation on a developing implant capsule are unknown, but they are very important in relation to the increased use of immediate reconstruction. Experiments were performed on rabbits to study the effects of postoperative radiation therapy on capsule contraction and thickness. The results of these experiments suggest that radiation has no effect on implant capsules.

    Purpose: To evaluate the effect of postoperative concurrent chemoradiotherapy using three-dimensional conformal radiotherapy and to identify the prognostic factors that influence survival in patients with extrahepatic bile duct cancer. Methods and Materials: We retrospectively analyzed the data from 101 patients with extrahepatic bile duct cancer who had undergone postoperative concurrent chemoradiotherapy using three-dimensional conformal radiotherapy. Of the 101 patients, 52 (51%) had undergone complete resection (R0 resection) and 49 (49%) had microscopic or macroscopic residual tumors (R1 or R2 resection). The median radiation dose was 50 Gy. Also, 85 patients (84%) underwent concurrent chemotherapy with 5-fluorouracil. Results: The median follow-up period was 47 months for the surviving patients. The 5-year overall survival rate was 34% for all patients. A comparison between patients with R0 and R1 resection indicated no significant difference in the 5-year overall survival (44% vs. 33%, p = .2779), progression-free survival (35% vs. 22%, p = .3107), or locoregional progression-free survival (75% vs. 63%, p = .2784) rates. An analysis of the first failure site in the 89 patients with R0 or R1 resection indicated isolated locoregional recurrence in 7 patients. Elevated postoperative carbohydrate antigen 19-9 level was an independent prognostic factor for overall survival (p = .001) and progression-free survival (p = .033). A total of 3 patients developed Grade 3 or greater late toxicity. Conclusion: Adjuvant concurrent chemoradiotherapy using three-dimensional conformal radiotherapy appears to improve locoregional control and survival in extrahepatic bile duct cancer patients with R1 resection. The postoperative carbohydrate antigen 19-9 level might be a useful prognostic marker to select patients for more intensified adjuvant therapy.

    In this work, postoperative lower limb kinematics are predicted with respect to preoperative kinematics, physical examination and surgery data. Data of 115 children with cerebral palsy that have undergone single-event multilevel surgery were considered. Preoperative data dimension was reduced utilizing principal component analysis. Then, multiple linear regressions with 80% confidence intervals were performed between postoperative kinematics and bilateral preoperative kinematics, 36 physical examination variables and combinations of 9 different surgical procedures. The mean prediction errors on test vary from 4° (pelvic obliquity and hip adduction) to 10° (hip rotation and foot progression), depending on the kinematic angle. The unilateral mean sizes of the confidence intervals vary from 5° to 15°. Frontal plane angles are predicted with the lowest errors, however the same performance is achieved when considering the postoperative average signals. Sagittal plane angles are better predicted than transverse plane angles, with statistical differences with respect to the average postoperative kinematics for both plane's angles except for ankle dorsiflexion. The mean prediction errors are smaller than the variability of gait parameters in cerebral palsy. The performance of the system is independent of the preoperative state severity of the patient. Even if the system is not yet accurate enough to define a surgery plan, it shows an unbiased estimation of the most likely outcome, which can be useful for both the clinician and the patient. More patients' data are necessary for improving the precision of the model in order to predict the kinematic outcome of a large number of possible surgeries and gait patterns.

    Abstract Previous study showed that patients under general anesthesia (GA) had nasopharyngeal secretions on the face at the end of ocular surgery, especially in propofol-based total intravenous anesthesia (TIVA), it might induce postoperative endophthalmitis. Therefore, we conducted a retrospective study to compare the incidence of endophthalmitis after ocular surgery under topical, inhalation anesthesia, and propofol-based TIVA in our medical center from 2011 to 2015. A total of 21,032 patients were included, and we evaluated epidemiologic factors, systemic diseases, other ocular pathologic characteristics, complications during the surgery, technique of ocular surgery, method of antibiotic prophylaxis, vitreous culture, and vision outcome in these patients. Fifteen endophthalmitis cases among 21,032 operations reported, equaling an incidence of 0.071%. The incidence rates under topical, inhalation anesthesia, and propofol-based TIVA were 0.083%, 0.039%, and 0%, respectively (P = 0.39). Moreover, the risk of endophthalmitis under GA (0.024%) was significantly lower than topical anesthesia (0.083%) (P < 0.001). We also found that elder was the risk factor for endophthalmitis following ocular surgery. In conclusion, propofol-based TIVA or inhalation anesthesia did not increase the risk of endophthalmitis after ocular surgery. Thus, GA was not a risk factor for postoperative endophthalmitis. By contrast, elder was the risk factor for postoperative endophthalmitis. PMID:28328861

    Takotsubo cardiomyopathy simulates acute myocardial infarction, and it is characterised by reversible left ventricular failure. A case of Takotsubo cardiomyopathy diagnosed after emergency angiography performed in a patient with evidence of acute myocardial infarction in the postoperative period will be described in this report. Transurethral resection of a bladder tumour (TUR-BT) was performed in a 92-year-old male patient by the urology clinic. The patient was transferred to the post-anaesthesia care unit after the operation. An echocardiography was performed because of the sudden onset of dyspnoea, tachycardia (140-150 beats per minute, rhythm-atrial fibrillation) and ST-segment elevation on electrocardiography (ECG) at the first postoperative hour, and midapical dyskinesia was detected at the patient. An immediate angiography was performed due to suspicion of acute coronary syndrome. Patent coronary arteries and temporary aneurysmatic dilatation of the apex of the heart were revealed by angiography. As a result of these findings, the patient was diagnosed with Takotsubo cardiomyopathy by the cardiology service. The patient was discharged uneventfully following 10 days in the intensive care unit. Aneurysm of the apex of the left ventricle and normal anatomy of the coronary arteries in the angiography have diagnostic value for Takotsubo cardiomyopathy. Diuretics (furosemide) and beta-blockers (metoprolol) are commonly used for the treatment of Takotsubo cardiomyopathy. Even though Takotsubo cardiomyopathy is a rare and benign disease, it should be kept in mind in patients suspected for acute myocardial infarction in the postoperative period.

    Cognitive decline after surgery in the elderly population is a major clinical problem with high morbidity. Hyperbaric oxygen (HBO) preconditioning can induce significant neuroprotection against acute neurological injury. We hypothesized that HBO preconditioning would prevent the development of postoperative cognitive impairment. Elderly male rats (20 months old) underwent stabilized tibial fracture operation under general anesthesia after HBO preconditioning (once a day for 5 days). Separate cohorts of animals were tested for cognitive function with fear conditioning and Y-maze tests, or euthanized at different times to assess the blood-brain barrier integrity, systemic and hippocampal proinflammatory cytokines, and caspase-3 activity. Animals exhibited significant cognitive impairment evidenced by a decreased percentage of freezing time and an increased number of learning trials on days 1, 3, and 7 after surgery, which were significantly prevented by HBO preconditioning. Furthermore, HBO preconditioning significantly ameliorated the increase in serum and hippocampal proinflammatory cytokines tumor necrosis factor-α, interleukin-1 β (IL-1β), IL-6, and high-mobility group protein 1 in surgery-challenged animals. Moreover, HBO preconditioning markedly improved blood-brain barrier integrity and caspase-3 activity in the hippocampus of surgery-challenged animals. These findings suggest that HBO preconditioning could significantly mitigate surgery-induced cognitive impairment, which is strongly associated with the reduction of systemic and hippocampal proinflammatory cytokines and caspase-3 activity.

    Twenty-four patients with stable angina pectoris were studied after aortocoronary bypass surgery with hypothermic cardiopulmonary bypass (CPB). Twelve patients (radiant heat supply group) were rewarmed during CPB to a nasopharyngeal temperature of at least 38 degrees C and a mean rectal temperature of 34.4 degrees C. Postoperatively they received radiant heat supply from a thermal ceiling. In addition, a heating water mattress was used during the end of the operation and heated, humidified inspired gases were administered intra- and postoperatively. The other 12 patients (combination heat supply group) had the rewarming during CPB extended until the rectal temperature exceeded 36 degrees C, but otherwise received the same treatment as the radiant heat supply group. The combination of extended rewarming during CPB and postoperative radiant heat supply significantly reduced oxygen uptake, carbon dioxide production and the required ventilation volumes during early recovery as compared with the values in the radiant heat supply group. The reduced metabolic demands were accompanied by lower cardiac index and oxygen delivery, which, however, were sufficient for adequate tissue perfusion as judged by the similarity in oxygen extraction and arterial base excess values in the two groups. The metabolic demands and ventilatory requirements were reduced to a level at which safe early extubation is possible.

    Introduction Risk factors associated with Carpal Tunnel Syndrome include repetitive use of hand and wrist, advanced age, obesity, pregnancy, diabetes mellitus and thyroid disease. Decompression of the median nerve is the last treatment of choice usually indicated when negative results to conservative treatments remain for three months. In this study, we aimed to find out whether hypothyroid patients would respond to CTS surgical decompression differently in comparison to healthy individuals. Methods This case control study was conducted on patients with CTS in need of surgical release who were refered to Shahid Faghihi hospital, International Branch of Shiraz University of Medical Sciences, Shiraz, Iran from January 2013 to January 2015. Twenty-five hypothyroid and 22 euthyroid patients were recruited. Hypothyroidism was diagnosed based on clinical symptoms and serum TSH level. All patients were followed for three weeks after surgery and a Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was completed for them pre and post operation. An electrophysiological study was performed during the same follow up period. Statistical analysis was performed using SPSS version 16. Results The CTS grade reported by electrophysiological study, decreased significantly 3 weeks after operation in comparison with preoperative grades (p<0.001). A significant decrease was observed in the immediate postoperative BCTQ scores compared to preoperative (p<0.001). Also a decrease was detected in the three weeks of postoperative follow up compared to immediate postoperative BCTQ scores (p<0.001) and preoperative BCTQ scores (p<0.001). Postoperative BCTQ scores of euthyroid patients decreased more in comparison to hypothyroid patients (p<0.001). Conclusion It seems that, hypothyroidism has an effect on postoperative outcome of carpal tunnel release. PMID:27790353

    BACKGROUND Retroperitoneal bleeding as a consequence of non-traumatic kidney or allograft rupture is well known, but there are no reports on hemorrhagia from a native kidney after allogeneic renal transplantation. Therefore, we present the first such case to be published and highlight the possibility of this complication after renal transplantation. CASE REPORT We report the case of a 28-year-old male patient who developed early post-transplant hemorrhagia from a ruptured native kidney. The patient underwent left-sided nephrectomy. Histopathological examination revealed ruptured hemangioma of the patient's native left kidney. The further postoperative period was not complicated. The patient was discharged on the 18th postoperative day, with good transplant function. CONCLUSIONS Transplantologists should be aware of the fact that in patients with uncontrolled blood pressure, native kidney hemangioma may rupture in the early post-transplant period, and it can be a life-threating and difficult to diagnose complication.

    Introduction. Postoperative pancreatic fistula formation remains the major complication after distal pancreatectomy. At our institution, we have recently developed a novel bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure technique of the pancreatic remnant during distal pancreatectomy. The aim of this study was to analyze the impact of this approach with regard to technical feasibility and overall postoperative outcome. Patients and Methods. 32 patients who underwent a bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure of the pancreatic remnant during distal pancreatectomy between 2012 and 2014 at our institution were analyzed for clinically relevant postoperative pancreatic fistula formation (Grades B and C according to ISGPF definition) and overall postoperative morbidity. Results. Three out of 32 patients (9.4%) developed Grade B pancreatic fistula, which could be treated conservatively. No Grade C pancreatic fistulas were observed. Postpancreatectomy hemorrhage occurred in 1 patient (3.1%). Overall postoperative complications > Clavien II were observed in 5 patients (15.6%). There was no postoperative mortality. Conclusion. The performance of a bovine serum albumin-glutaraldehyde sealed hand sutured fish-mouth closure of the pancreatic remnant was shown to be technically feasible and may lead to a significant decrease of postoperative pancreatic fistula formation after distal pancreatectomy.

    Postoperative complications and related risk factors after lung reduction surgery are analyzed based on a review of the literature. In particular the pathogenesis of some of postoperative respiratory disorders is carefully assessed. Most commonly cardiac arrhythmias, respiratory failure, bronchopleural fistula are observed. Main risk factors for postoperative complications are old age, chronic obstructive pulmonary disease, coronary disease, poor nutritional state, neoadjuvant therapy. Attention should be paid to all these factors, both in preoperative assessment and postoperative care, to prevent and promptly treat postoperative complications.

    Aspergillus is a ubiquitous fungus which can cause a variety of clinical syndromes. This fungus has emerged as agent of systemic infections and has therefore gained considerable public health importance. This paper describes two cases of invasive aspergillosis caused by A. fumigatus in immuno-suppressed patients and underscores the importance of early identification of Aspergillus infection associated with systemic lupus erythematosus and cardiac postoperative complications.

    BACKGROUND Previous studies have reported poor graft regeneration after living donor liver transplantation (LDLT) due to inappropriate portal venous flow (PVF). In this study, we investigated the perioperative factors affecting postoperative PVF after LDLT. MATERIAL AND METHODS The perioperative data of 366 LDLT patients were retrospectively reviewed. The average PVF on postoperative days 1, 3, and 5 was measured and dichotomized at a cut-off value for patient survival of 1,477 mL/min. Perioperative variables, including coagulation profiles, were compared between high and low postoperative PVF groups. The factors potentially significant (p<0.1) for a low postoperative PVF were evaluated in a univariate analysis, followed by the development of a predictive model for a low postoperative PVF. RESULTS A low post-LDLT PVF was determined in 113 patients (30.9%). The univariate analysis identified systemic hypertension, LDLT duration, average mean blood pressure, and insulin administration as the significantly related factors. Other significant factors were a plasma fibrinogen, at the anhepatic phase and 1 h after graft reperfusion, as well as the platelet count at the anhepatic phase. After multivariate adjustment, plasma fibrinogen 1 h after graft reperfusion against a recipient background of systemic hypertension was independently associated with a low mean postoperative PVF. CONCLUSIONS A low mean PVF during the early post-LDLT period was independently related to the plasma fibrinogen level 1 h after graft reperfusion, and to a history of systemic hypertension. Thus, the practice of aggressive supplementation of plasma fibrinogen during the immediate post-reperfusion period merits serious consideration.

    Background Research on post-transplant care has predominantly focused on predictors of readmission with little attention to emergency department (ED) visits. The goal of this study was to describe early postoperative ED care of transplant recipients. Methods A secondary database analysis of adult patients who underwent abdominal organ transplantation between January 1, 2008 and December 31, 2013 and sought ED care within one year post-transplantation was conducted. Survival was compared using the Kaplan-Meier method with log-rank test. Cox proportional hazards regression analysis was performed to adjust for pertinent covariates. Results A total of 1,900 abdominal organ transplants were performed during the study period. Of these, 37% (N=711) transplant recipients sought care in the ED (1,343 total visits) with 1.89 mean ED visits per recipient. Of recipients seen in the ED, 58% received a kidney transplant and 28% received a liver transplant, with 45% of recipients presenting within the first 60 postoperative days. The most common chief complaints were gastroenterological (17%) and abnormal laboratory values or vital signs (17%). In total, 74% of recipients were readmitted and 50% of admitted patients were discharged in less than 24 hours. Transplant recipients with ED visits had lower 3-year graft (81% vs. 87%; p<0.001) and patient (89% vs. 93%; p=0.002) survival. Conclusion Transplant recipients have a high frequency of ED visits in the first post-transplantation year and high rates of subsequent hospital admission. Further investigation is needed to understand what drives recipient presentation to the ED and create care models that achieve the best outcomes. PMID:26050012

  13. Prevention and management of postoperative urinary retention after urogynecologic surgery

    2014-01-01

    Postoperative urinary retention (POUR) is a frequent consequence of gynecologic surgery, especially with surgical correction of urinary incontinence and pelvic organ prolapse. Estimates of retention rates after pelvic surgery range from 2.5%–43%. While there is no standard definition for POUR, it is characterized by impaired bladder emptying, with an elevation in the volume of retained urine. The key to management of POUR is early identification. All patients undergoing pelvic surgery, especially for the correction of incontinence or prolapse, should have an assessment of voiding function prior to discharge. There are several ways to assess voiding function – the gold standard is by measuring a postvoid residual. Management of POUR is fairly straightforward. The goal is to decompress the bladder to avoid long-term damage to bladder integrity and function. The decision regarding when to discontinue catheter-assisted bladder drainage in the postoperative period can be assessed in an ongoing fashion by measurement of postvoid residual. The rate of prolonged POUR beyond 4 weeks is low, and therefore most retention can be expected to resolve spontaneously within 4–6 weeks. When POUR does not resolve spontaneously, more active management may be required. Techniques include urethral dilation, sling stretching, sling incision, partial sling resection, and urethrolysis. While some risk of POUR is inevitable, there are risk factors that are modifiable. Patients that are at higher risk – either due to the procedures being performed or their clinical risk factors – should be counseled regarding the risks and management options for POUR prior to their surgery. Although POUR is a serious condition that can have serious consequences if left untreated, it is easily diagnosed and typically self-resolves. Clinician awareness of the condition and vigilance in its diagnosis are the key factors to successful care for patients undergoing surgical repair. PMID:25210477

    BACKGROUND/OBJECTIVES: Pain-related misbeliefs among health care professionals (HCPs) are common and contribute to ineffective postoperative pain assessment. While standardized patients (SPs) have been effectively used to improve HCPs’ assessment skills, not all centres have SP programs. The present equivalence randomized controlled pilot trial examined the efficacy of an alternative simulation method – deteriorating patient-based simulation (DPS) – versus SPs for improving HCPs’ pain knowledge and assessment skills. METHODS: Seventy-two HCPs were randomly assigned to a 3 h SP or DPS simulation intervention. Measures were recorded at baseline, immediate postintervention and two months postintervention. The primary outcome was HCPs’ pain assessment performance as measured by the postoperative Pain Assessment Skills Tool (PAST). Secondary outcomes included HCPs knowledge of pain-related misbeliefs, and perceived satisfaction and quality of the simulation. These outcomes were measured by the Pain Beliefs Scale (PBS), the Satisfaction with Simulated Learning Scale (SSLS) and the Simulation Design Scale (SDS), respectively. Student’s t tests were used to test for overall group differences in postintervention PAST, SSLS and SDS scores. One-way analysis of covariance tested for overall group differences in PBS scores. RESULTS: DPS and SP groups did not differ on post-test PAST, SSLS or SDS scores. Knowledge of pain-related misbeliefs was also similar between groups. CONCLUSIONS: These pilot data suggest that DPS is an effective simulation alternative for HCPs’ education on postoperative pain assessment, with improvements in performance and knowledge comparable with SP-based simulation. An equivalence trial to examine the effectiveness of deteriorating patient-based simulation versus standardized patients is warranted. PMID:22184553

    Purpose This study was conducted to identify the effectiveness of a preoperative comprehensive geriatric assessment (CGA) for predicting postoperative morbidity in elderly patients who underwent surgery for colorectal cancer. Methods Elderly patients (≥70 years old) who underwent surgery for colorectal cancer at a tertiary hospital in Korea were identified, and their cases were analyzed using data from a prospectively collected database to establish an association between major postsurgical complications and 'high-risk' patient as defined by the CGA. Results A total of 240 patients, with a mean age of 76.7 ± 5.2 years, were enrolled. Ninety-five patients (39.6%) were classified as "high-risk" and 99 patients (41.3%) as having postoperative complications. The univariate analysis indicated that risk factors for postoperative complications were age, American Society of Anesthesiologists physical status classification, serum hemoglobin, carcinoembryonic antigen, cancer stage, and "high-risk" status. The multivariable analyses indicated that "high-risk" status (odds ratio, 2.107; 95% confidence interval, 1.168–3.804; P = 0.013) and elevated preoperative carcinoembryonic antigen (odds ratio, 2.561; 95% confidence interval, 1.346–4.871, P = 0.004) were independently associated with postoperative complications. A multivariable analysis of the individual CGA domains indicated that high comorbidities and low activities of daily living were significantly related with postoperative complications. Conclusion A preoperative CGA indicating "high-risk" was associated with major postoperative complications in elderly patients who underwent surgery for colorectal cancer. Thus, using the CGA to identify elderly colorectal-cancer patients who should be given more care during postoperative management may be clinically beneficial. PMID:27847786

    Locally advanced non-small-cell lung carcinoma (NSCLC) is a very heterogeous disease, the role of postoperative radiation therapy (PORT) in pN2 patients with completly resected NSCLC remains controversial. Although an improvment in local control has been described in several studies, the effect on survival has been contradictory or inconclusive. Retrospective evaluation suggest a positive effect of PORT in high risk patients with pN2 disease: RI-resected NSCLC, bulky and multilevel N2. However further evaluation of PORT in prospectively randomized studies in completely resected pN2 NSCLC is needed.

    Formation of heterotopic bone (HTB) following total hip replacement may partially or completely ankylose the joint space, causing pain and/or limiting the range of motion. Patients at high risk for formation of HTB postoperatively include those with previous HTB formation, heterotopic osteoarthritis, and active rheumatoid spondylitis. Patients in these high risk groups have a 63-69% incidence of post-operative HTB formation, usually seen radiographically by 2 months post-operation. From 1980-1986 twenty-nine hips in 28 consecutively treated patients were irradiated post-operatively at the UCLA Center for the Health Sciences. The indication for irradiation was documented HTB formation previously in 26 of the 27 hips presented below. From 1980-1982 patients received 20 Gray (Gy) in 2 Gy fractions; from 1982-1986 the dose was reduced to 10 Gy in 2 Gy fractions. Twenty-seven hips in 26 patients completed therapy and were available for evaluation, with a minimum of 2 month follow-up, and a median follow-up of 12 months. Three of 27 hips developed significant HTB (Brooker grade III or IV) post-operatively, whereas 5 of 27 hips developed minor, nonsymptomatic HTB (Brooker grade I). When irradiation was begun by postoperative day 4, 0 of 17 hips formed significant HTB. If irradiation began after post-operative day 4, 3 of 10 hips formed significant HTB (Brooker grade III or IV). These 3 hips received doses of 10 Gy in one hip and 20 Gy in the other 2 hips. There were no differences in the incidence or severity of side effects in the 10 Gy vs. the 20 Gy treatment groups. Eighteen hips received 10 Gy, 8 hips 20 Gy and, 1 hip 12 Gy. In conclusion, 10 Gy in 5 fractions appears as effective as 20 Gy in 10 fractions at preventing post-operative formation of HTB. For optimal results, treatment should begin as early as possible prior to post-operative day 4.

    Background Antegrade cerebral perfusion (ACP) typically is used with deep hypothermia for cerebral protection during aortic arch reconstructions. The impact of ACP on cerebral oxygenation and serum creatinine at a more tepid 25 °C was studied in newborns and children. Methods Between 2010 and 2014, 61 newborns and children (<5 years old) underwent aortic arch reconstruction using moderate hypothermia (25.0±0.9 °C) with ACP and a pH-stat blood gas management strategy. These included 44% Norwood-type operations, 30% isolated arch reconstructions, and 26% arch reconstructions with other major procedures. Median patient age at surgery was 9 days (range, 3 days–4.7 years). Cerebral oxygenation (NIRS) was monitored continuously perioperatively for 120 hours. Serum creatinine was monitored daily. Results Median cardiopulmonary bypass (CPB) and cross clamp times were 181 minutes (range, 82–652 minutes) and 72 minutes (range, 10–364 minutes), respectively. ACP was performed at a mean flow rate of 46±6 mL/min/kg for a median of 48 minutes (range, 10–123 minutes). Cerebral and somatic NIRS were preserved intraoperatively and remained at baseline postoperatively during the first 120 hours. Peak postoperative serum creatinine levels averaged 0.7±0.3 mg/dL for all patients. There were 4 (6.6%) discharge mortalities. Six patients (9.8%) required ECMO support. Median postoperative length of hospital and intensive care unit (ICU) stay were 16 days(range, 4–104 days) and 9 days (range, 1–104 days), respectively. Two patients (3.3%) received short-term peritoneal dialysis for fluid removal, and none required hemodialysis. Three patients (4.9%) had an isolated seizure which resolved with medical therapy, and none had a neurologic deficit or stroke. Conclusions ACP at 25 °C preserved perioperative cerebral oxygenation and serum creatinine for newborns and children undergoing arch reconstruction. Early outcomes are encouraging, and additional study is warranted to

    Postoperative imaging after spinal surgery is usually performed to document the correct positioning of implants or to rule out complications if patients still suffer from pain after surgery. Depending on the question various imaging modalities can be used all of which have benefits and limitations. Conventional X-ray is used for the documentation of the correct positioning of spinal implants, stability (olisthesis) and during follow-up to rule out fractures or instability of the implants, whereas soft tissue changes cannot be completely assessed. Besides these indications, imaging is usually performed because of ongoing symptoms (pain for the most part) of the patients. Soft tissue changes including persistent or recurrent herniated disc tissue, hematoma or infection can best be depicted using magnetic resonance imaging (MRI) which should be performed within the immediate postoperative period to be able to distinguish physiological development of scar tissue from inflammatory changes in the area of the surgical approach. Often imaging alone cannot differentiate between these and imaging can therefore only be considered as an adjunct. Computed tomography is the modality of choice for the evaluation of bony structures and an adjunct of new therapies such as image-guided application of cement for kyphoplasty or vertebroplasty.

    Context: Alterations in taste and smell, including but not limited to anosmia, ageusia, hypogeusia, and dysgeusia, have been described in association with various medications, including anesthetic agents. Frequently, these symptoms occur 1-2 weeks after medication administration and last several months. While such a phenomenon is a rare occurrence, it nonetheless can significantly impact patients’ satisfaction and quality of life. Evidence Acquisition: The methodology consisted of a thorough literature search using the MEDLINE and Cochrane databases utilizing keywords such as anosmia, ageusia, olfactory disorders, postoperative, and anesthesia. Results: Our results yielded several previously published case report, and were not limited to a specific type of anesthesia. Based on available literature, we review the physiology of taste and smell as well as the medications associated with loss of these senses. We describe perioperative agents that could lead to postoperative complications associated with anosmia and and ageusia. Conclusions: Based on available literature recommendations for anesthesiologists caring for patients at risk for this occurrence are presented in this review. The symptoms are usually temporary as in the majority of the patients the sensory receptor cells are able to regenerate themselves after injury. Anesthesia providers need to aware of this phenomenon to be able to reassure patients and possibly avoid anesthetic techniques associated with anosmia and ageusia. PMID:25599025

    2008-06-01

    Postoperative anastomotic biliary strictures can occur after surgery in bile ducts belonging to transplanted or native (nontransplanted) livers. The majority of postoperative anastomotic strictures encountered by interventional radiologists are most likely in liver transplant recipients due to the large and growing liver transplant recipient population worldwide compared with patients with native livers and biliary enteric anastomoses. They occur after 2.5 to 13% of liver transplantations and they represent at least one-half of biliary strictures encountered after liver transplantation. Anastomotic biliary strictures are considered technical in nature, accentuated by fibrosis and scarring that may be secondary to, if not exacerbated by, graft ischemia. There are numerous variables in the percutaneous transhepatic balloon dilation protocols applied to treat anastomotic biliary strictures. These include (1) types of balloons, (2) how long balloons are inflated, (3) how frequently patients return for additional dilation sessions, and (4) the interval(s) at which they return. No alteration in these variables has proven to improve long-term patency. In addition, new technology such as cutting balloons and stents has not been fully evaluated to determine their effect on long-term patency. The current article describes the overall theme of balloon dilation protocols for the management of anastomotic biliary strictures and discusses possible future management of such strictures.

    This study aimed at reviewing a contemporary series of patients who underwent robotic renal and adrenal surgery by a single surgeon at a tertiary referral academic medical center over a 6-year period, specifically focusing on the unique and serious complication of post-operative rhabdomyolysis of the dependent lower extremity. The cases of 315 consecutive patients who underwent robotic upper tract surgery over a 6-year period from August 2008 to June 2014 using a standardized patient positioning were reviewed and analyzed for patient characteristics and surgical variables that may be associated with the development of post-operative rhabdomyolysis. The incidence of post-operative rhabdomyolysis in our series was 3/315 (0.95%). All three affected patients had undergone robotic nephroureterectomy. Those patients who developed rhabdomyolysis had significantly higher mean Body Mass Index, Charlson Comorbidity Index, and median length of stay than those who did not. The mean OR time in the rhabdomyolysis group was noted to be 52 min longer than the non-rhabdomyolysis group, though this value did not reach statistical significance. Given the trends of increasing obesity in the United States and abroad as well as the continued rise in robotic upper tract urologic surgeries, urologists need to be increasingly vigilant for recognizing the risk factors and early treatment of the unique complication of post-operative rhabdomyolysis.

    Postamputation management is an important determinant of recovery from amputation. However, consensus on the most effective postoperative management strategies for individuals undergoing transtibial amputation (TTA) is lacking. Dressings can include simple soft gauze dressings, thigh-high rigid cast dressings, shorter removable rigid dressings, and prefabricated pneumatic dressings. Postoperative prosthetic attachments can be added to all but simple soft dressings. These dressings address the need to cleanly cover a fresh surgical wound, but not all postoperative dressings are designed to facilitate the strategic goals of preventing knee contractures, reducing edema, protecting from external trauma, or facilitating early weight bearing. The type of dressing and management strategy often overlap and are certainly interrelated. Current protocols and decisions are based on local practice, skill, and intuition. The current available literature is challenging, and difficulties include variations in healing potential, in comorbidity, in surgical-level selection, in techniques and skill, in experience with postoperative strategies, and with poorly defined outcome criteria. This paper reviews the published literature and compares measures of safety, efficacy, and clinical outcomes of the various techniques. Analysis of 10 controlled studies supported only 4 of the 14 claims cited in uncontrolled, descriptive studies.

    2014-01-01

    Arrhythmias are a known complication after cardiac surgery and represent a major cause of morbidity, increased length of hospital stay, and economic costs. However, little is known about incidence, risk factors, and treatment of early postoperative arrhythmias. Both tachyarrhythmias and bradyarrhythmias can present in the postoperative period. In this setting, atrial fibrillation is the most common heart rhythm disorder. Postoperative atrial fibrillation is often self-limiting, but it may require anticoagulation therapy and either a rate or rhythm control strategy. However, ventricular arrhythmias and conduction disturbances can also occur. Sustained ventricular arrhythmias in the recovery period after cardiac surgery may warrant acute treatment and long-term preventive strategy in the absence of reversible causes. Transient bradyarrhythmias may be managed with temporary pacing wires placed at surgery, but significant and persistent atrioventricular block or sinus node dysfunction can occur with the need for permanent pacing. We provide a complete and updated review about mechanisms, risk factors, and treatment strategies for the main postoperative arrhythmias. PMID:24511410

    Ten parameters, including delayed cutaneous hypersensitivity testing (DCH), were evaluated with regard to their predictive value in instances of postoperative septic complications. In 302 patients undergoing surgical treatment, 45 complications, including wound infection, abscess, pneumonia and sepsis, were seen postoperatively in 42 patients. When these patients were compared with 260 patients without complications, hemoglobin, leukocyte count, serum albumin, total protein, blood sedimentation rate, age and sex were found not to contribute to the prediction of postoperative complications. In DCH testing, the complication rate increased from 7.5 per cent in normergic patients to 20.6 per cent in anergic patients. With increasing length and severity of operation, the complication rate increased from 6.5 to 26.4 per cent and from 6.5 to 31.8 per cent, respectively. Only in severe, long lasting operations could DCH testing differentiate the complication risk. Normergic patients had a 8.6 per cent complication rate; hypoergic patients, 36.6 per cent, and anergic patients, 37.5 per cent. The results of DCH testing did not correlate with the complication rate in any of the other operative groups. In conclusion, the predictive value of DCH testing is clearly greater in groups of patients highly affected by the operative trauma. The results of this study show that it is important to consider both host defense mechanisms and environmental factors in the assessment of operative risks.

    Corneal diseases cause severe visual impairment that necessitates corneal transplantation and frequently repetitive procedures due to graft rejection. We tested the hypothesis that exposure of donor corneas to recipient serum-derived factors during eye banking triggers a preoperative adaptation that is beneficial for postoperative tolerance. Donor corneas were incubated in a medium containing human serum (HS) obtained in each case from the prospective graft recipient in order to individually expose the donor cornea to the recipient's serum. All recipient serum-adapted corneas (RSACs) fulfilled the clinical criteria required by the national law and were transplanted successfully. The postoperative ophthalmological examination extended up to 8 years. All RSACs were tolerated by their recipients and did not cause postoperative complications and no rejection. Proteomic analysis of corneas cultivated in culture medium containing either fetal calf serum (FCS) that is routinely used for cornea banking or HS revealed different patterns of proteins. HS-cultured corneas showed a greater proteomic similarity with native human corneas than did the FCS-cultured corneas, indicating a differential nutrification of the cultured corneal tissue by HS-derived factors. The clinical results show for the first time that postoperative complications such as tissue intolerance and graft rejection might be managed if the corneal tissue is individually adapted to the recipient's serum trophic factors. This new donor tissue treatment procedure offers incontrovertible advantages and could be adapted for low-risk eyes as well as other transplantable tissues.

    C57BL/6NCrl male mice (n = 60; age, 6 to 7 wk) underwent partial hepatectomy or no surgery and were given 1 of 3 analgesics pre- and postoperatively. Food and water consumption, body weight, running wheel activity, locomotor activity, and serum corticosterone concentrations were measured before and after surgery. Mice that were surgically manipulated weighed significantly less on days 1 through 3 after surgery than did mice not manipulated surgically. On the day of surgery, the surgery groups consumed significantly less feed (-1.5±0.35 g) than did nonsurgery groups. There were no differences in water consumption on any day between surgery and nonsurgery groups or among the 3 analgesic groups. For running wheel activity, significant decreases in the surgery groups were seen at day 1 after surgery compared with baseline. Surgery groups that received buprenorphine and meloxicam returned to baseline activity levels on day 2 after surgery. Open-field testing revealed no significant differences in locomotor activity in any groups; however, posttreatment locomotor activity in the buprenorphine nonsurgery group was increased compared with baseline, and posttreatment locomotor activity in the flunixin meglumine surgery group was decreased compared with baseline. Serum corticosterone concentrations were within normal limits regardless of treatment in all groups. Comparison of the overall results indicated that meloxicam and buprenorphine, at the dose given, appear to be suitable postoperative analgesics for partial hepatectomy in mice. Flunixin meglumine at the given dosage (2.5 mg/kg) may not provide adequate analgesia for partial hepatectomy.

    This study aims to evaluate the viability of a clinical model of remote ischemic preconditioning (RIPC) and its analgesic effects. It is a prospective study with twenty (20) patients randomly divided into two groups: control group and RIPC group. The opioid analgesics consumption in the postoperative period, the presence of secondary mechanical hyperalgesia, the scores of postoperative pain by visual analog scale, and the plasma levels interleukins (IL-6) were evaluated. The tourniquet applying after spinal anesthetic block was safe, producing no pain for all patients in the tourniquet group. The total dose of morphine consumption in 24 hours was significantly lower in RIPC group than in the control group (p = 0.0156). The intensity analysis of rest pain, pain during coughing and pain in deep breathing, showed that visual analogue scale (VAS) scores were significantly lower in RIPC group compared to the control group: p = 0.0087, 0.0119, and 0.0015, respectively. There were no differences between groups in the analysis of presence or absence of mechanical hyperalgesia (p = 0.0704) and in the serum levels of IL-6 dosage over time (p < 0.0001). This clinical model of remote ischemic preconditioning promoted satisfactory analgesia in patients undergoing conventional cholecystectomy, without changing serum levels of IL-6. PMID:27446611

    This cross-sectional observational study was to establish the preoperative assessment of serum albumin level as indicator for morbidity following cancer surgery and to reduce the incidence of related postoperative complications. Therefore this study was undertaken to assess the morbidity associated with low serum level albumin and identify it as a risk factor following cancer surgery in Bangladeshi population. This study included 312 patients with malignancy who were waiting for surgery or within 60 days of postoperative period were enrolled for the study from indoor of surgical oncology department, National Institute of Cancer Research & Hospital (NICR&H), Dhaka, Bangladesh. Then the patients were submitted for further study to evaluate the preoperative fitness in terms of nutritional assessment - both clinical and biological especially serum albumin level. All the clinical (pre & post-operative including complication, if any), investigation findings were recorded accordingly. Statistical correlation was discovered between BMI and morbidity but no statistical correlation was found between WL >10% and major surgical complications of either infectious or noninfectious origin (p=NS). Conversely, a substantial statistical correlation was found between Hb% or albumin <30gm/l and major surgical complications (either infectious or noninfectious) (p<0.001). The serum albumin level below 30gm/l is a significant risk factor for oncological postoperative major complications (MC).

    The immunologic status of patients undergoing cardiopulmonary bypass as investigated. Rheumatoid factor, cryoglobulinemia and serum immune complexes were looked for. Studies were performed before the operation and eight or fifteen days later. From the results, it is concluded that the immunologic changes that occur in the immediate postoperative period cannot be interpreted because of the profound modifications resulting from cardiopulmonary bypass.

    As many as 2247 patients with different clinical forms of diphtheria were examined. Antidiphtheric serum (ADS) was administered in 1556 children, the dosage being determined by condition of the patient. Serum sickness developed at day 7 to 9 in 24 (1.5%); 10 patients were found to run a mild course, 14--moderately severe. 6 patients had allergic reactions: 3--to antibiotic (penicillin), urticaria type, 1--to pertussoid-tetanic anatoxin, 2 had pollinosis-type reaction. Thus, serum sickness has practical value, which fact requires a detailed allergic history together with skin tests to be performed before the administration of ADS.

    Background Although circumcision for phimosis in children is a minor surgical procedure, it is followed by pain and carries the risk of increased postoperative anxiety. This study examined predictive factors of postoperative pain and anxiety in children undergoing circumcision. Methods We conducted a prospective cohort study of children scheduled for elective circumcision. Circumcision was performed applying one of the following surgical techniques: sutureless prepuceplasty (SP), preputial plasty technique (PP), and conventional circumcision (CC). Demographics and base-line clinical characteristics were collected, and assessment of the level of preoperative anxiety was performed. Subsequently, a statistical model was designed in order to examine predictive factors of postoperative pain and postoperative anxiety. Assessment of postoperative pain was performed using the Faces Pain Scale (FPS). The Post Hospitalization Behavior Questionnaire study was used to assess negative behavioral manifestations. Results A total of 301 children with a mean age of 7.56 ± 2.61 years were included in the study. Predictive factors of postoperative pain measured with the FPS included a) the type of surgical technique, b) the absence of siblings, and c) the presence of postoperative complications. Predictive factors of postoperative anxiety included a) the type of surgical technique, b) the level of education of mothers, c) the presence of preoperative anxiety, and d) a history of previous surgery. Conclusions Although our study was not without its limitations, it expands current knowledge by adding new predictive factors of postoperative pain and postoperative anxiety. Clearly, further randomized controlled studies are needed to confirm its results. PMID:26495079

    Further information on the endogenous arginine vasopressin (AVP) response in patients with postoperative systemic inflammatory response syndrome (SIRS) and vasodilatory shock would provide more insight into the pathophysiology of SIRS-associated cardiovascular failure and help indicate AVP therapy. Patients after uncomplicated abdominal surgery without SIRS (n = 10), critically ill patients after noncardiac surgery with SIRS (n = 9), and patients with SIRS plus vasodilatory shock (n = 22) were included in this prospective trial. Plasma AVP (radioimmunoassay) and copeptin (immunoluminometric assay) concentrations together with clinical parameters were documented daily during the first 7 days postoperative. The AVP response significantly differed between the three groups. Patients without SIRS had lower AVP concentrations than SIRS patients with (P = 0.001) or without shock (P = 0.003). Patients with SIRS and shock had higher AVP levels than patients with SIRS alone (P < 0.001). Arginine vasopressin decreased over time (P = 0.007) in all groups. At day 28, nonsurvivors had higher AVP levels than did survivors (P < 0.001). In SIRS patients without shock, serum osmolarity was indirectly associated with AVP levels, whereas mean arterial blood pressure and serum osmolarity were associated with AVP in SIRS patients with shock. Arginine vasopressin and copeptin correlated significantly with each other (P < 0.001; r = 0.76). In patients without hemofiltration, copeptin levels predicted 28-day mortality with high sensitivity and specificity. The postoperative AVP response in noncardiac surgery patients seems well maintained. The possibility that AVP plays a contributory role in the failure to restore vascular tone in patients with vasodilatory shock cannot be excluded but seems less important than in septic or postcardiotomy shock.

    The aim of the present study was to evaluate the usefulness of a closed-loop system (STG-55; Nikkiso, Tokyo, Japan), a type of artificial endocrine pancreas for the continuous monitoring and control of intraoperative blood glucose, for preventing postoperative acute kidney injury (AKI) in patients undergoing hepatectomy. Thirty-eight patients were enrolled in this study. Glucose concentrations were controlled with either a manual injection of insulin based on a commonly used sliding scale (manual insulin group, n = 19) or the programmed infusion of insulin determined by the control algorithm of the artificial endocrine pancreas (programmed insulin group, n = 19). After the induction of anesthesia, a 20-G intravenous catheter was inserted into the peripheral forearm vein of patients in the programmed insulin group and connected to an artificial endocrine pancreas (STG-55). The target range for glucose concentrations was set to 100-150 mg/dL. The mean serum creatinine concentrations of preoperative, postoperative 24 and 48 h were 0.72, 0.78, and 0.79 mg/dL in the programmed insulin group, and 0.81, 0.95, and 1.03 mg/dL in the manual insulin group, respectively. Elevations in serum creatinine concentrations postoperative 48 h were significantly suppressed in the programmed insulin group. The STG-55 closed-loop system was effective for maintaining strict blood glucose control during hepatectomy with minimal variability in blood glucose concentrations and for suppressing elevations in serum creatinine concentrations. Strict blood glucose control by an artificial endocrine pancreas during hepatectomy may prevent postoperative AKI.

    Background: Considering the important role of pituitary gland in regulating various endocrine axes and its unique anatomical location, various postoperative complications can be anticipated resulting from surgery on pituitary tumors. We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay) in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe. PMID:25191182

    Background Dipyrone (metamizole) is a non-steroidal anti-inflammatory drug used in some countries to treat pain (postoperative, colic, cancer, and migraine); it is banned in others because of an association with life-threatening blood agranulocytosis. This review updates a 2001 Cochrane review, and no relevant new studies were identified, but additional outcomes were sought. Objectives To assess the efficacy and adverse events of single dose dipyrone in acute postoperative pain. Search methods The earlier review searched CENTRAL, MEDLINE, EMBASE, LILACS and the Oxford Pain Relief Database to December 1999. For the update we searched CENTRAL, MEDLINE,EMBASE and LILACS to February 2010. Selection criteria Single dose, randomised, double-blind, placebo or active controlled trials of dipyrone for relief of established moderate to severe postoperative pain in adults. We included oral, rectal, intramuscular or intravenous administration of study drugs. Data collection and analysis Studies were assessed for methodological quality and data extracted by two review authors independently. Summed total pain relief over six hours (TOTPAR) was used to calculate the number of participants achieving at least 50% pain relief. Derived results were used to calculate, with 95% confidence intervals, relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over six hours. Use and time to use of rescue medication were additional measures of efficacy. Information on adverse events and withdrawals was collected. Main results Fifteen studies tested mainly 500 mg oral dipyrone (173 participants), 2.5 g intravenous dipyrone (101), 2.5 g intramuscular dipyrone (99); fewer than 60 participants received any other dose. All studies used active controls (ibuprofen, paracetamol, aspirin, flurbiprofen, ketoprofen, dexketoprofen, ketorolac, pethidine, tramadol, suprofen); eight used placebo controls.

    Postoperative alopecia is the temporary or permanent loss of hair that occurs following prolonged immobilization during general anesthesia and intubation. The clinical and histopathologic aspects of a typical case are described and the literature reviewed. Localized pressure-induced ischemia is the likely cause. Patients at highest risk for permanent hair loss include those subject to cardiac or gynecologic surgical procedures where the combined intraoperative and postoperative intubation time exceeds twenty-four hours. Frequent intraoperative and postoperative head repositioning provides excellent prophylaxis.

    Purpose: Postoperative chemoradiotherapy in gastric cancer improves locoregional control and survival. Reports on late toxicity, however, have been scarce thus far. Because renal toxicity is one of the most serious late complications in upper abdominal radiotherapy, we prospectively analyzed kidney function in patients who underwent postoperative chemoradiotherapy for gastric cancer. Patients and Methods: In 44 patients, Tc{sup 99m}-thiatide renography was performed before and at regular intervals after postoperative chemoradiotherapy. The left-to-right (L/R) ratio was used as an index of the relative kidney function. Mean L/R values were calculated for four follow-up time intervals. For all patients, kidney V{sub 20} (percentage of the volume of the kidney that received more than 20 Gy) and mean dose of both kidneys were retrieved from the three-dimensional dose-volume histograms. Results: We observed a progressive decrease in left renal function of 11% (p = 0.012) after 6 months, up to 52% (p < 0.001) after >18 months. The V{sub 20} (left kidney) and mean left kidney dose were identified as parameters associated with decreased kidney function. Mean serum creatinine was increased from 74.6 {mu}mol/L before treatment to 86.1 {mu}mol/L at 1 year after chemoradiotherapy (p < 0.001). In patients with a follow-up of 18-28 months, one case of severe renovascular hypertension was observed. Conclusion: A progressive relative functional impairment of the left kidney in patients after postoperative chemoradiotherapy for gastric cancer is demonstrated. To optimize the survival benefit that can be established with adjuvant regimens, strategies to minimize the dose to the kidneys and other critical organs should be explored.

    Swelling or oedema of forehead or eyelids is a common consequence of hair transplantation surgery. However, this results in increased morbidity and absence from work due to unaesthetic appearance. To study various physical and therapeutic modalities to reduce or completely prevent the occurrence of such oedema. Three hundred forty hair transplant patients were recruited in the study and were categorized into 8 groups depending upon the intervention employed. There were 32 dropouts in the study due to various reasons. Patients who were administered steroid with tumescent solution had the highest number of patients without oedema, with only 3 out of 117 patients developing oedema. Physical measures like position of head during sleeping, application of occlusion bands or ice packs did not show satisfactory results. Addition of triamcinolone to tumescent anaesthetic solution is a very effective technique of preventing post-operative swelling.

    Gastric cancer remains a disease with poor prognosis, mainly due to its late diagnosis. Surgery remains as the only treatment with curative intent, where the goal is radical resection with free-margin gastrectomy and extended lymphadenectomy. Over the last two decades there has been an improvement on postoperative outcomes. However, complications rate is still not negligible even in high volume specialized centers and are directly related mainly to the type of gastric resection: total or subtotal, combined with adjacent organs resection and the extension of lymphadenectomy (D1, D2 and D3). The aim of this study is to analyze the complications specific-related to lymphadenectomy in gastric cancer surgery. PMID:28138657

    Hemodynamic optimization begins with a medical assessment to identify the high-risk patients. This stratification is needed to customize the choice of hemodynamic support that is best adapted to the patient's level of risk, integrating the use of the least invasive procedures. The macro-circulatory hemodynamic approach aims to maintain a balance between oxygen supply (DO2) and oxygen demand (VO2). Volume replacement plays a crucial role based on the titration of fluid boluses according to their effect on measured stroke volume or indices of preload dependency. Good function of the microcirculatory system is the best guarantee to achieve this goal. An assessment of the DO2/VO2 ratio is needed for guidance in critical situations where tissue hypoxia may occur. Overall, all of these strategies are based on objective criteria to guide vascular replacement and/or tissue oxygenation in order to improve the patient's post-operative course by decreasing morbidity and hospital stay.

    According to the Diagnostic and Statistical Manual IV (DSM IV), conversion disorder is classified as a somatoform illness and defined as an alteration or loss of physical function because of the expression of an underlying psychological ailment. This condition, previously known as hysteria, hysterical neurosis, or conversion hysteria occurs rarely, with an incidence of 11-300 cases per 100,000 people (American Psychiatric Association. Diagnostic and statistical manual of mental disorders. 4th edn. Washington, DC: American Psychiatric Association, 1994). Presentation after an anesthetic is exceptional. After thorough review of the literature, fewer than 20 cases have been documented, with only two instances in patients younger than 18 years of age after general anesthesia; both were mild in nature. We present a severe case of postoperative conversion disorder that developed upon emergence from anesthesia in a previously healthy 16-year-old girl following direct laryngoscopy with vocal fold injection.

    1983-02-01

    Five cases of clinically suspected osteoid osteomas were studied by preoperative injection of technetium-99m methylene disphosphonate, intraoperative localization with a radiation-sensitive scintillation probe, and postoperative examination of the entire tissue specimen (including the presumed nidus and surrounding bone). Microradiography and light microscopy were also used. In addition, a new autoradiography technique was introduced in which the excised surgical specimen was placed on undeveloped x-ray film for pathologic localization, diagnosis of the lesions, and a study of the relative intensity of radioactive uptake in the nidus vs. surrounding bone. Autoradiography revealed that the nidus showed the greatest concentration of radioactivity, followed by the surrounding bone. The authors conclude that /sup 99m/Tc can be used clinically in localizing osteoid osteomas and that preoperative and intraoperative scanning can assist in conservative surgical excision. For small lesions, autoradiography assists the pathologist in identifying an osteoid osteoma.

    Retrospective analysis of 1027 percutaneous radioendoscopic surgeries for upper urinary tract stones was performed. Postoperative acute pyelonephritis was the most common complication (11.2%), the frequency of which was significantly dependent on the presence of source of infection in the urinary tract, and the frequency of intra- and postoperative complications. When performing PPN, patients with urolithiasis and with the presence of the initial infection in the urinary tract, intra- and postoperative complications should be referred to the group of patients with a high risk of postoperative infectious and inflammatory complications. The analysis showed that the development of acute pyelonephritis after PPN increases the cost of treatment by 25%.
