Molecular characterisation of fowl adenovirus associated with hydropericardium hepatitis syndrome in broiler and layer breeders in Azerbaijan.

BACKGROUND: Fowl adenovirus-4 is a causative agent of hydropericardium hepatitis syndrome (HHS) in chickens and has been frequently reported from many countries. Fowl adenoviruses cause severe disease and mortality in broiler and layer breeders in Azerbaijan. Therefore, in this study, pathological lesions and the dissemination of fowl adenovirus-4 into the visceral organs of infected birds were investigated as well as molecular characterisation of detected strains. For this, liver, heart and spleen from 20 necropsied chickens originated from a broiler breeder flock and a layer breeder flock were embeded on the FTA cards and the samples were analysed for adenovirus-DNA by PCR and sequencing. RESULTS: The findings of necropsy in both broiler and layer breeder chickens were similar, and the liver was severely effected showing hepatitis, and the heart with hydropericardium lesions. The kidneys were swollen with haemorrhages and small white foci on the surface of the spleens were noted. Intestinal congestion and ecchymotic hemorrhages were also observed in some birds. Fowl adenovirus-4-DNA was detected by PCR in all collected organs of 20 birds. The sequence analysis revealed that fowl adenovirus-4 present in Azerbaijan and close similarity of the hexon genes of the adenoviruses existing in the Middle East, North America, far east and Indian subcontinent were determined by phylogenetic analysis. However, sequence diversity was detected from the adenovirus strains circulating in Europe, North and South America. CONCLUSIONS: This study indicates the impact of fowl adenovirus-4 on the poultry health and production, and improved disease control and prevention strategies are necessary to reduce the HHS disease in chickens in Azerbaijan.

Comparison of scoring systems for predicting short- and long-term type 2 diabetes remission after bariatric surgery.

INTRODUCTION: Our study aimed to compare the short- and particularly long-term type 2 diabetes mellitus (T2DM) remission prediction abilities of ABCD, individualised metabolic surgery (IMS), DiaRem2, Ad-DiaRem and DiaBetter scoring systems in Turkish adult type 2 diabetic morbidly obese patients who underwent bariatric surgery. PATIENTS AND METHODS: Our study was planned as a retrospective cohort study. A total of 137 patients with T2DM, including 78 sleeve gastrectomy (SG) and 59 Roux-en-Y gastric bypass (RYGB) patients, were included in the 1st-year evaluation after bariatric surgery, and a total of 115 patients with T2DM, including 64 SG and 51 RYGB patients, were included in the evaluation at the end of the 5th year. RESULTS: In the 1st year after bariatric surgery, area under the ROC curve (AUC) values for diabetes remission scores were 0.863 for Ad-DiaRem, 0.896 for DiaBetter, 0.840 for DiaRem2, 0.727 for ABCD and 0.836 for IMS. At 5 years after bariatric surgery, the AUC values for diabetes remission were 0.834 for Ad-DiaRem, 0.888 for DiaBetter, 0.794 for DiaRem2, 0.730 for ABCD and 0.878 for IMS. CONCLUSIONS: According to our study, the DiaBetter score provided a better AUC value than the other scores both in the short and long term but showed similar predictive performance to Ad-DiaRem in the short term and IMS in the long term. We believe that DiaBetter and Ad-DiaRem scores might be more appropriate for short-term assessment and DiaBetter and IMS scores for long-term remission assessment.

DNA fragmentation, chromosomal aberrations, and multi-toxic effects induced by nickel and the modulation of Ni-induced damage by pomegranate seed extract in Allium cepa L.

This study was designed to assess the recovery effect of pomegranate seed extract (PSEx) against nickel (Ni)-induced damage in Allium cepa. Except for the control group treated with tap water, five experimental groups were exposed to 265 mg L-1 PSEx, 530 mg L-1 PSEx, 1 mg L-1 NiCI2, 265 mg L-1 PSEx + 1 mg L-1 NiCI2, and 530 mg L-1 PSEx + 1 mg L-1 NiCI2, respectively. The toxicity of Ni was examined through the analysis of physiological (germination percentage, weight gain, and root length), cytotoxicity (mitotic index), genotoxicity (micronucleus, chromosomal anomalies, and Comet test), and biochemical (malondialdehyde, proline, chlorophyll a and chlorophyll b contents, the activities of superoxide dismutase and catalase) parameters. Meristematic cell defects were also investigated. The NiCl2-DNA interaction was evaluated through spectral shift analysis. Values of all physiological parameters, mitotic index scores, and chlorophyll contents decreased while micronucleus frequency, DNA tail percentage, chromosomal anomalies, proline, MDA, and enzyme activities increased following Ni administration. According to the tail DNA percentage scale, Ni application caused "high damage" to DNA. Ni-induced chromosomal anomalies were fragment, sticky chromosome, vagrant chromosome, bridge, unbalanced chromatin distribution, reverse polarization, and nucleus with bud. NiCl2-DNA interaction caused a hyperchromic shift in the UV/Vis spectrum of DNA by spectral profile analysis. Ni exposure impaired root meristems as evidenced by the formation of epidermis cell damage, flattened cell nucleus, thickened cortex cell wall, and blurry vascular tissue. Substantial recovery was seen in all parameters with the co-administration of PSEx and Ni. Recovery effects in the parameters were 18-51% and 41-84% in the 265 mg L-1 PSEx + 1 mg L-1 NiCI2 and 530 mg L-1 PSEx + 1 mg L-1 NiCI2 groups, respectively. The Comet scale showed that PSEx applied with Ni reduced DNA damage from "high" to "moderate." Ni-induced thickened cortex cell wall and blurry vascular tissue damage disappeared completely when 530 mg L-1 PSEx was mixed with Ni. PSEx successfully reduced the negative effects of Ni, which can be attributed to its content of antioxidants and bioactive ingredients.

The Role of Adenovirus-36 in Adults with Obesity-Induced Type 2 Diabetes.

BACKGROUND: Obesity may also develop due to a viral infection caused by adenovirus 36. We aimed to detect the presence of neutralizing antibodies against Ad-36 in adult patients who developed type 2 diabetes due to obesity (BMI ≥ 30 kg/m2). METHODS: The patient group (PG) was composed of 80 obese people with type 2 diabetes, the patient control group (PCG) was composed of 40 non-obese people with type 2 diabetes, and the healthy control group (HCG) was com-posed of 40 non-obese people without type 1 or type 2 diabetes in this case-control study. The presence of Ad-36 neutralizing antibodies was studied by serum neutralization assay. RESULTS: A significant difference was found between the PG and HCG in terms of Ad-36 antibody positivity (p < 0.0001) but no significant difference was detected between the PG and the PCG (p > 0.05). BMI, serum leptin, adiponectin, and triglyceride levels were significantly higher in the PG (p < 0.05). Conversely, TNF-α and IL-6 levels were significantly lower in the PG (p < 0.0001). When the two groups were compared, the mean levels of total cho-lesterol and LDL in the PG were found to be high, although not significant (p > 0.05). In type 2 diabetes patients (n = 120), age, BMI, HDL, LDL, triglyceride, total cholesterol, Ad-36 presence, leptin, adiponectin, TNF-α, and IL-6 parameters were taken as independent variables for logistic regression. While BMIs was found to be significant (odds ration [OR] = 2.358; p = 0.0001, 95% Cl 1.507 - 3.690, Ad-36 presence was found to be a significant (OR = 27.352; p = 0.003, 95% Cl 3.157 - 236.961). Our study showed that BMI and Ad-36 increase type 2 diabetes risk by 2.3 and 27.3-fold in the PG and PCG (type 2 diabetes patients) versus the HCG. There was also a significant difference between PCG and HCG. CONCLUSIONS: We suggest that Ad-36 seropositivity is also a risk factor for the development of type 2 diabetes independent of being obese.

Assessment of the diagnostic performance of the 1 mg dexamethasone suppression test in class 3 obese patients.

Objective. This study was aimed to evaluate the prevalence of Cushing's syndrome and the diagnostic performance of the 1 mg dexamethasone suppression test in class 3 obese patients. Methods. Anthropometric measurements and other laboratory data, including 1 mg dexamethasone suppression test of 753 class 3 obese patients, who applied to the Endocrinology and Metabolism Outpatient Clinic for the pre-bariatric surgery evaluation between 2011 and 2020, were evaluated retrospectively. Results. An abnormal response to the 1 mg dexamethasone suppression test (cortisol ≥1.8 mcg/dl) was observed in 24 patients and the presence of Cushing's syndrome was confirmed by additional tests in 6 patients. The prevalence of abnormal dexamethasone suppression test was 3.18% and the prevalence of Cushing's syndrome 0.79%. The specificity value was determined as 97.5% for 1 mg dexamethasone suppression test with cortisol threshold value ≥1.8 mcg/dl. Conclusions. The prevalence of Cushing's syndrome was found to be low in class 3 obese patients and 1 mg of dexamethasone suppression test had a very sufficient performance for Cushing's syndrome screening in this patient group.

Comparison of scoring systems for predicting remission of type 2 diabetes in sleeve gastrectomy patients.

Introduction: This study aims to compare the predictive capacity of ABCD, DiaRem2, Ad-DiaRem, and DiaBetter scoring systems for type 2 diabetes mellitus (T2DM) remission in Turkish adult morbidly obese patients who underwent SG. Methods: This retrospective cohort study included 80 patients who underwent sleeve gastrectomy (SG) operation who were diagnosed with T2DM preoperatively, and had at least one-year follow-up after surgery. Because bariatric surgery is performed on patients with class III obesity (BMI ≥ 40 kg/m2) or class II obesity (BMI ≥ 35 kg/m2) with obesity releated comorbid conditions in our hospital, our study cohort consisted of these patients. Results: The diagnostic performance of the DiaBetter, DiaRem2, Ad-DiaRem and ABCD for identifying diabetes remission, assessed by the AUC was 0.882 (95% CI, 0.807-0.958, p < 0.001), 0.862 (95% CI, 0.779-0.945, p < 0.001), 0.849 (95% CI, 0.766-0.932, p < 0.001) and 0.726 (95% CI, 0.601-0.851, p = 0.002), respectively. The AUCs of the Ad-Diarem, DiaBetter and DiaRem2 were statistically higher than AUC of the ABCD (all p-value < 0.001). Besides, there was no statistically significant difference in AUCs of the Ad-Diarem, DiaBetter and DiaRem scores (all p-value > 0.05). Conclusion: Ad-Dairem, DiaBetter and DaiRem scoring systems were found to provide a successful prediction for diabetes remission in sleeve gastrectomy patients. It was observed that the predictive power of the ABCD scoring system was lower than the other systems. We think that the use of scoring systems for diabetes remission, which have a simple use, will become widespread.

Effect of 6% Hydroxyethyl Starch 130/0.4 on Inflammatory Response and Pulmonary Function in Patients Having Cardiac Surgery: A Randomized Clinical Trial.

BACKGROUND: Cardiac surgery with cardiopulmonary bypass induces a profound inflammatory response that, when severe, can lead to multiorgan system dysfunction. Preliminary data suggest that administration of hydroxyethyl starch (HES) solutions may mitigate an inflammatory response and improve pulmonary function. Our goal was to examine the effect of 6% HES 130/0.4 versus 5% human albumin given for intravascular plasma volume replacement on the perioperative inflammatory response and pulmonary function in patients undergoing cardiac surgery. METHODS: This was a subinvestigation of a blinded, parallel-group, randomized clinical trial of patients undergoing elective aortic valve replacement surgery at the Cleveland Clinic main campus, titled "Effect of 6% Hydroxyethyl Starch 130/0.4 on Kidney and Haemostatic Function in Cardiac Surgical Patients." Of 141 patients who were randomized to receive either 6% HES 130/0.4 or 5% human albumin for intraoperative plasma volume replacement, 135 patients were included in the data analysis (HES n = 66, albumin n = 69). We assessed the cardiopulmonary bypass-induced inflammatory response end points by comparing the 2 groups' serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and macrophage migration inhibitory factor (MIF), measured at baseline and at 1 and 24 hours after surgery. We also compared the 2 groups' postoperative pulmonary function end points, including the ratio of partial pressure of arterial oxygen to fraction of inspired oxygen (Pao2:Fio2 ratio), dynamic lung compliance, oxygenation index (OI), and ventilation index (VI) at baseline, within 1 hour of arrival to the intensive care unit, and before tracheal extubation. The differences in the postoperative levels of inflammatory response and pulmonary function between the HES and albumin groups were assessed individually in linear mixed models. RESULTS: Serum concentrations of the inflammatory markers (TNF-α, IL-6, MIF) were not significantly different (P ≥ .05) between patients who received 6% HES 130/0.4 or 5% albumin, and there was no significant heterogeneity of the estimated treatment effect over time (P ≥ .15). The results of pulmonary function parameters (Pao2:Fio2 ratio, dynamic compliance, OI, VI) were not significantly different (P ≥ .05) between groups, and there was no significant heterogeneity of the estimated treatment effect over time (P ≥ .15). CONCLUSIONS: Our investigation found no significant difference in the concentrations of inflammatory markers and measures of pulmonary function between cardiac surgical patients who received 6% HES 130/0.4 versus 5% albumin.

The Mid-Term Effects of Transit Bipartition with Sleeve Gastrectomy on Glycemic Control, Weight Loss, and Nutritional Status in Patients with Type 2 Diabetes Mellitus: a Retrospective Analysis of a 3-Year Follow-up.

BACKGROUND: Metabolic surgery is an effective treatment method for glycemic control and weight loss in obese patients with type 2 diabetes mellitus (T2DM). This study aimed to present the mid-term metabolic effects and weight loss results of the patients with T2DM who underwent transit bipartition with sleeve gastrectomy (TB-SG). METHODS: A total of 32 obese patients with T2DM who underwent TB-SG were included in the study. The T2DM remission status after surgery was evaluated. The postoperative glycemic variables, weight loss, lipid profile, and nutritional profile were also compared with the baseline values. RESULTS: At 36 months after surgery, T2DM remission occurred in 27 patients (84.3%) and the mean BMI decreased from 44.70 ± 9.34 to 29.75 ± 2.19 kg/m2. The percentage of total weight loss (TWL) and excess weight loss (EWL) was 33.84% and 77.19%, respectively. The mean LDL values significantly decreased compared to baseline; however, the mean HDL did not significantly differ. No significant difference was observed regarding the mean albumin, vitamin B12, and folic acid levels. CONCLUSION: TB-SG procedure seems promising in terms of T2DM remission and weight loss with less malnutrition and vitamin deficiency in treating obese patients with T2DM.

Prognostic Utility of KDIGO Urine Output Criteria After Cardiac Surgery.

OBJECTIVES: Kidney Disease: Improving Global Outcomes (KDIGO) guidelines include assessment of creatinine and urine output to identify acute kidney injury (AKI). Whether urine output is an accurate indicator of AKI after cardiac surgery, however, is unclear. The authors' goal was to examine whether cardiac surgery patients who fulfilled criteria for AKI by KDIGO urine output criteria also demonstrated kidney injury by elevated creatinine, other kidney biomarkers, or had worse clinical outcomes. DESIGN: Secondary analysis of prospectively collected data from a clinical trial, "6% Hydroxyethyl starch 130/0.4 in Cardiac Surgery (NCT02192502)." SETTING: Academic, quaternary care hospital. PARTICIPANTS: Patients undergoing elective aortic valve replacement INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: One hundred forty-one patients were classified into AKI stage by KDIGO urine output criteria within 24 hours after surgery. Kidney biomarkers (serum creatinine, urinary neutrophil gelatinase-associated lipocalin [NGAL], urinary interleukin-18 [IL-18]) and hospital and intensive care unit length of stay were analyzed across AKI stages. Urine output criteria classified four times as many patients with AKI than creatinine criteria (95 [67%] v 21 [15%]). Most patients meeting KDIGO urine output criteria for AKI postoperatively did not satisfy KDIGO creatinine criteria for AKI within one week (77 of 95 [81%]) or six-to-12 months (27 of 29 [93%]). Higher AKI stage assessed by urine output was not associated with higher NGAL, IL-18, or longer hospital or intensive care unit stays. CONCLUSIONS: Acute kidney injury classified by KDIGO urine output criteria was not associated with other biomarkers of kidney injury or worse patient outcomes. These data suggested that KDIGO urine output criteria after cardiac surgery may overclassify AKI stage; further research is needed.

Evaluation of the choroidal thickness and retinal nerve fiber layer and visual fields in morbid obesity: Does bariatric surgery affect retinal structure and function?

Purpose: The study aimed to investigate the changes in choroidal thickness (CT), retinal nerve fiber layer thickness (RNFL), and visual field parameters in morbidly obese patients following bariatric surgery. Methods: The study included 40 morbidly obese patients with body mass indexes (BMI) ≥40 who had undergone bariatric surgery (Group 1) and 40 age-and sex-matched healthy subjects with normal BMI values (Group 2). RNFL and CT measurements by optical coherence tomography (OCT) and visual field test were performed preoperatively and the 1st, 6th, and 12th months postoperatively. CT measurements were obtained from the subfoveal, nasal (N), and temporal (T) regions at distances of 500 µm and 1,000 µm from the fovea. Results: No significant pathology was detected during ophthalmological examinations following bariatric surgery. The BMIs were found to be significantly lower in all of the periods after bariatric surgery (P < 0.0001). The CT measurements decreased significantly in all periods after bariatric surgery (P < 0.0001). No differences were found in terms of the mean RNFL thicknesses in all postoperative periods (P = 0.125). Visual field tests showed no significant changes during scheduled visits. (P = 0.877). No visual field defect was detected in any patient during the follow-up periods after bariatric surgery. Conclusion: These results have suggested that CT is positively correlated with BMI and decreased with a reduction in BMI progressively. Nutritional disorders resulting from malabsorption have not caused any nutritional optic neuropathy and visual field defect for at least the first postoperative year after bariatric surgery.

The Short-Term Effects of Transit Bipartition with Sleeve Gastrectomy and Distal-Roux-en-Y Gastric Bypass on Glycemic Control, Weight Loss, and Nutritional Status in Morbidly Obese and Type 2 Diabetes Mellitus Patients.

PURPOSE: The aim of this study was to compare the postoperative metabolic and nutritional outcomes after transit bipartition with sleeve gastrectomy (TB-SG) and distal-Roux-en-Y gastric bypass (D-RYGB). MATERIALS AND METHODS: A retrospective evaluation was made of 109 morbidly obese patients who underwent TB-SG or D-RYGB. Primary outcomes included metabolic variables such as glycemic control and serum lipid levels, and secondary outcomes consisted of nutritional deficiencies and weight loss after surgical procedures. RESULTS: During the study period, 83 and 26 patients underwent D-RYGB and TB-SG, respectively. The preoperative characteristics and nutritional status of the groups were similar. D-RYGB resulted in significantly higher weight loss rates in the first 3 months, but the percentage of excess weight loss (EWL %) was not different in the 12-month follow-up period. Although D-RYGB provided faster glycemic control due to early weight loss, there was no difference between the two groups. At the end of the follow-up period, the TB-SG was associated with significantly less deficiency of vitamin D, vitamin B12, iron, and folic acid. Anastomosis leakage was more common in the D-RYGB technique. The overall complication rates of the groups were similar. CONCLUSION: TB-SG is a safe and effective alternative to D-RYGB for the treatment of obesity-related metabolic disorders with fewer nutritional deficiencies.

Pain during sexual activity and ejaculation following hernia repair: A retrospective comparison of transabdominal preperitoneal versus Lichtenstein repair.

Pain during sexual activity and ejaculation are the unspoken long-term complications of groin hernia repair. Laparoscopic surgical techniques are associated with decreased post-operative pain and earlier return to daily activities, but its effect on these complications is unclear. This study aims to investigate the effect of transabdominal preperitoneal repair (TAPP) on de-novo pain during sexual intercourse and ejaculation and to compare with open repair. For this reason, two groups were determined according to the surgical technique: the Lichtenstein repair and the TAPP groups and a questionnaire was sent to the patients a minimum of 6 months following the surgery. A total of 317 patients included, as 115 in TAPP and 202 in Lichtenstein repair group. No significant difference was observed concerning pre-operative pain during sexual activity and ejaculation in both groups (p = .75, p = .56). Following the surgery, the number of patients experiencing painful sexual activity was significantly higher in the Lichtenstein repair group compared to the TAPP group (19.3% vs. 11.3%, respectively, p = .03). The post-operative painful ejaculation rate was also significantly lower for the TAPP group (p = .04). The lower rates of post-operative dysejaculation and pain during sexual activity can be achieved with the advantage of laparoscopic surgery.

Association Between Preoperative Statin Use and Respiratory Complications After Noncardiac Surgery: A Retrospective Cohort Analysis.

BACKGROUND: Statins possess pleiotropic effects, which potentially benefit noncardiovascular conditions. Previous work suggests that statins reduce inflammation and prevent acute respiratory distress syndrome and infections. However, there is a paucity of data regarding potential benefits of statins on respiratory and infectious complications, particularly after noncardiac surgery. We therefore evaluated respiratory and other complications in noncardiac surgery patients taking or not taking statins preoperatively. METHODS: We obtained data from the Cleveland Clinic Perioperative Health Documentation System and evaluated medical records of 92,139 inpatients who had noncardiac surgery. Among these, 31,719 patients took statins preoperatively. Statin patients were compared to nonstatin patients on incidence of intraoperative use of albuterol and postoperative respiratory complications for primary analysis. Infectious complications, cardiovascular complications, in-hospital mortality, and duration of hospitalization were compared for secondary analyses, using inverse probability of treatment weighting to control for potential confounding. RESULTS: Statin use was associated with lower odds of intraoperative albuterol treatment (odds ratio [OR] = 0.89; 97.5% confidence interval [CI], 0.82-0.97; P = .001; number needed to treat [NNT] = 216). Postoperative respiratory complications were also less common (OR = 0.82; 98.75% CI, 0.78-0.87; P < .001). Secondarily, statin use was associated with lower odds of infections, cardiovascular complications, in-hospital mortality, and shorter duration of hospitalization. The interaction between statin use and sex was significant (with significance criteria P < .10) for all primary and secondary outcomes except intraoperative use of albuterol. CONCLUSIONS: Preoperative statin use in noncardiac surgical patients was associated with slightly reduced odds of postoperative respiratory, infectious, and cardiovascular complications. However, the NNTs were high. Thus, despite the fact that statins appeared to be associated with lower odds of various complications, especially cardiovascular complications, our results do not support using statins specifically to reduce noncardiovascular complications after noncardiac surgery.

Characterisation of Fowl Adenovirus (FAdV-8b) Strain Concerning the Geographic Analysis and Pathological Lesions Associated with Inclusion Body Hepatitis in Broiler Flocks in Turkey.

INTRODUCTION: Fowl adenovirus can cause important diseases in chickens such as inclusion body hepatitis, hepatitis hydropericardium syndrome, and gizzard erosion and ulceration. Inclusion body hepatitis has been regularly reported from many countries. This is the first case report from Turkey, describing an outbreak of inclusion body hepatitis in broiler farms due to fowl adenovirus-8b (FAdV-8b). MATERIAL AND METHODS: Broiler flocks with mortality about 10% were visited in Turkey, and necropsy was performed on dead birds. Samples were subjected to PCR assay to detect FAdV and other viral pathogens. After sequencing, phylogenetic analysis was performed and the nucleotide sequences of hexon genes were compared with the FAdV sequences data available in GenBank. RESULTS: Clinical signs such as anorexia, depression, ruffled feathers, huddling, and greenish diarrhoea were observed. Mortality started at the 8th day of age and ranged from 10% to 14%. Necropsy showed severe hepatitis, jaundice, and pancreatitis. The main necropsy findings included a pale, enlarged, haemorrhagic, and friable liver along with swollen and haemorrhagic kidneys and spleen. PCR and sequence analysis revealed the presence of fowl adenovirus serotype 8b (FAdV-E). CONCLUSION: This is the first report on characterisation and the pathological lesions associated with FAdV in broilers in Turkey. Our findings suggest that FAdV strains could be an emerging pathogen in Turkish broilers and could actively contribute to hepatitis and immunosuppression.

Association between higher BMI and postoperative pain and opioid consumption in pediatric inpatients - A retrospective cohort study.

BACKGROUND: Childhood and adolescent obesity increased in recent decades, and caregivers face an increasing number of obese pediatric surgical patients. Some clinical and pharmacogenetic data suggest that obese patients have altered pain sensitivity and analgesic requirements. OBJECTIVE: To test the primary hypothesis that increased BMI in pediatric patients is associated with increased pain during the initial 48 postoperative hours. Secondarily, we tested whether BMI is associated with increased opioid consumption during the same period. DESIGN: Retrospective single-center cohort study. SETTING: Pediatric surgical wards in a tertiary medical center. PATIENTS: A total of 808 opioid naïve patients aged 8 to 18 years having elective non-cardiac surgery with hospital stay of at least 48 h in the Cleveland Clinic between 2010 and 2015. INTERVENTIONS: None. MEASUREMENTS: Using U.S. Centers for Disease Control definitions for childhood weight classifications, we retrospectively evaluated the association between body mass index (BMI) percentile and time-weighted average pain scores and opioid consumption. We used multivariable linear regression to test for an association with postoperative pain scores, and multivariable gamma regression to test for an association with postoperative opioid consumption (in mg morphine equivalents Kg-1). RESULTS: BMI was not associated with postoperative pain after general, orthopedic, or neuro-spinal surgeries. Pain increased by 0.07 [98.75% CI: (0.01, 0.13), Padj < 0.05] points per 5 percentile increase in BMI after neuro-cranial surgery. Higher BMI was associated with a decrease in postoperative opioid consumption (mean change [95% CI] -2.12% [-3.12%, -1.10%] in morphine equivalents Kg-1 per 5 percentile increase in BMI, P < 0.001). CONCLUSION: We found no clinically important increase in pain scores or opioid consumption in association with higher BMI in patients 8 to 18 years of age recovering from elective non-cardiac surgery.

Evaluation of the possible involvement of Ad-36-induced adipogenesis and coronary artery disease development in mediastinal adipose tissue samples.

Mediastinal fat has been suggested to be associated with cardiovascular diseases such as carotid stiffness, atherosclerosis and coronary artery calcification. We investigated the possible role of Ad-36-induced obesity in the pathogenesis of the coronary artery disease (CAD). Ad-36 DNA was investigated in the anterior mediastinal fat tissue samples of obese adults with CAD. Seventy-five obese adults with left main coronary artery (LMCA) disease, 28 non-obese adults with valvular heart diseases, and 48 healthy individuals without cardiovascular problems were included as the obese patient group (OPG), non-obese patient group (NOG) and healthy control group (HCG), respectively. We also simultaneously investigated Ad-36 antibodies by serum neutralization test (SNA), and measured leptin and adinopectin levels. Ad-36 antibodies were detected only in 10 patients (13.3%) within the 75 OPG. A statistically significant difference was detected between OPG, NOG and HCG in terms of Ad-36 antibody positivity (p>0.05). Ad-36 DNA was not detected in mediastinal tissue samples of OPG and NOP without PCR inhibitors. We suggest that Ad-36 may not have an affinity for mediastinal adipose tissue in obese patients with left main CAD and valvular heart diseases. Ad-36 antibody positivity results are not sufficient to reach a causal relationship.

The efficiency of low-dose hepatitis B immunoglobulin plus nucleos(t)ide analogs in preventing posttransplant hepatitis B virus recurrence

Background/aim: In this study, the efficiency of using low-dose hepatitis B immunoglobulin (HBIG) plus antiviral treatment according to individual needs has been evaluated in posttransplant hepatitis B virus (HBV) patients. Materials and methods: We retrospectively evaluated 179 patients who were admitted between 2009 and 2014. Five thousand IU intravenous HBIG was given in the anhepatic phase, and 400 IU/day intramuscular (IM) HBIG was given in the posttransplant period. After HBsAg seroconversion, 400 IU IM HBIG was continued as prophylaxis every two weeks. Results: The average follow-up period was 26 (2­65) months. Seventy patients had hepatocellular carcinoma (HCC). The HBV recurrence was 4.5% in the first year, and 5.8% in the third year. The HBsAg became negative in 11 (2­63) days, and anti-HBs became positive in 9 (1­31) days. HBsAg positivity occurred in 6 patients during the follow-up period. Five of these patients were those who underwent transplantation due to HCC. In 5 of the HCC patients, in whom HBsAg became positive, tumor recurrence was observed after 0.3­9.9 months. HBsAg positivity was more frequently detected in patients with HCC (P = 0.009). Conclusion: The HBV recurrence should be evaluated as a predictor of the HCC recurrence in patients who were transplanted due to HCC.

Iliac Artery Injury During Lumbar Disc Hernia Surgery.

BACKGROUND: Vascular injury complications during lumbar discectomy are rare but potentially life-threatening. Therefore, an early diagnosis and effective treatment management is required for these complications. CASE DESCRIPTION: A 50-year-old female patient was admitted to our outpatient clinic with severe back and right leg pain. She underwent surgery for right L4-5 extruded disc herniation with general anesthesia. Sudden arterial hemorrhage occurred during discectomy performed with straight disc forceps and was controlled using hemostatic materials, with no significant decrease in blood pressure. However, the patient became hypotensive near the end of the operation. The incision was quickly closed, and she was turned to supine position. Emergency abdominal ultrasound, computed tomography, and computed tomography angiography revealed an injury of the left main iliac artery, which was repaired by endovascular stenting. Laparotomy and Bogota bag were applied because of increased intrabdominal pressure at 3 hours postoperative. In addition, a retroperitoneal catheter was placed into the area of the right retroperitoneal hematoma on the first postoperative day. Tissue plasminogen activator was administered through the catheter. On postoperative day 3, the Bogota bag was removed, and the abdomen was closed. The patient was discharged without neurodeficit on day 27. Her abdominal fascial defect was closed with a synthetic graft after 5 months. CONCLUSIONS: Although lumbar discectomy is one of the most commonly performed neurosurgical procedures, the routine rules of discectomy should not be neglected. Early detection and a multidisciplinary approach can help prevent mortality in the event of vascular injury.

Hepatitis B and hepatocellular carcinoma recurrence after living donor liver transplantation: The role of the Milan criteria.

BACKGROUND/AIMS: The aim of this study was to evaluate the effect of the Milan criteria on the hepatitis B virus (HBV) and hepatocellular carcinoma (HCC) recurrence in patients who underwent living donor liver transplantation due to HBV-induced cirrhosis and HCC. MATERIALS AND METHODS: We evaluated a total of 142 patients, 88 who underwent transplantation due to HBV-induced cirrhosis and 54 due to HCC, between 2009 and 2014. In the posttranplant period, after the HBsAg seroconversion, 400 IU of hepatitis B immunoglobulin were applied intramuscularly every 2 weeks, and daily nucleos(t)ide analogs were continued as prophylaxis. The HBV recurrence was defined as the presence of HBsAg in serum. Patients were screened for alpha-fetoprotein levels and imaging for evaluation of HCC recurrence. RESULTS: The average follow-up period was 26 (2-65) months. Fifty-four patients had HCC. The HCC recurrence was observed in 12 patients during the follow-up period. The HBV recurrence was observed in four patients. Three of the patients who developed HBV recurrence had liver transplantation due to HCC. Tumor recurrence was observed 1.4-12 months following the HBV recurrence. The HCC recurrence within the Milan criteria and beyond the Milan criteria was 0% vs. 28.4 % in the first year and 3.4% vs. 47.5% in the third year. The cumulative incidence of the HBV recurrence was 2.8% and 3.7% for the first year and 3.7% for the third year. The HBV recurrence was more frequently detected in patients with HCC (p=0.048), especially with HCC beyond the Milan criteria (p=0.044). CONCLUSION: The HBV recurrence should be evaluated as a predictor of the HCC recurrence in patients who underwent liver transplantation due to HCC with exceeding Milan criteria.
