Abstract
BACKGROUND Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. METHODS The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. RESULTS A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). CONCLUSION Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov).

Abstract
Neuroendocrine tumors (NETs) are a rare subset of malignancies in the biliary tract that may have an aggressive and initially asymptomatic course. A 93-year-old female presented with four days of abdominal pain with associated nausea, jaundice, and brown-colored urine. A CT scan revealed a soft-tissue lesion measuring 1.9 x 1.5 x 1.9 cm within the distal-most aspect of the common bile duct and papilla with marked bile duct dilatation, pancreatic duct dilatation, and multiple hepatic lesions of varying sizes. The biliary stricture was palliated with a stent via endoscopic retrograde cholangiopancreatography. Biopsies taken from the biliary mass were consistent with a well-differentiated NET: World Health Organization, Grade 3. The patient was minimally symptomatic after stenting and was discharged home. She ultimately decided not to pursue further treatment and passed away two months after the initial presentation. Currently, surgical excision is considered the main and only curative treatment for localized NETs, although chemotherapy and radiation therapy may be suitable. Early detection and treatment of these rare NETs in the biliary tree can potentially result in curative treatment.

Abstract
OBJECTIVES The benefits of reduction in low-density lipoprotein cholesterol by evolocumab by nearly 60% has not been evaluated among kidney transplant recipients to our knowledge. We assessed the efficacy and safety of evolocumab, a proprotein convertase subtilisin/kexin-9 inhibitor, in reducing lipids and cardiovascular events among kidney transplant recipients in a randomized controlled study. MATERIALS AND METHODS Between June 2017 and June 2019, we enrolled 197 kidney transplant recipients with high cardiovascular risk score (>20). Patients who received evolocumab (140 mg/2 weeks) comprised group 1 (n = 98), and patients maintained on statin therapy comprised group 2 (n = 99). We followed patients clinically and with necessary laboratory investigations over 24 months. RESULTS The 2 groups had comparable demographic characteristics (P > .05). Before enrollment in the study, smokers were significantly more prevalent in group 1, whereas posttransplant diabetes mellitus was more prevalent in group 2 (P = .033). Moreover, baseline serum creatinine was higher in group 1, whereas immunosuppression was equivalent in both groups (P > .05). We found no significant differences between the 2 groups concerning cardiovascular events, and both graft and patient outcomes were comparable (P > .05). The higher baseline cholesterol in group 1 (5.5 vs 4.7 mmol/L; P < .001) decreased significantly after 3 months and thereafter (P = .031) compared with levels in group 2 and baseline values (P < .001). We reported 2 cases of acute myocardial infarction and 1 atrial fibrillation in group 2. CONCLUSIONS Proprotein convertase subtilisin/kexin-9 inhibitors, as an added therapy to statins, are safe and effective in treating hypercholesterolemia after kidney transplant. Evolocumab can minimize cardiovascular events after kidney transplant in patients with high events at baseline. Longer-term trials with larger number of patients are needed to confirm its beneficial effects on cardiovascular complications and patient and graft survival.

Abstract
INTRODUCTION Cardiovascular and renal complications define the outcomes of diabetic kidney transplant recipients (KTRs). The new diabetes medications have changed the management of diabetes. However, transplant physicians are still reluctant to use sodium-glucose cotransporter 2 inhibitors (SGLT2i) and Glucagon-like peptide-1 receptor agonists (GLP-1RA) post kidney transplantation due to fear of drug related complications and lack of established guidelines. PATIENTS AND METHODS We collected 1-year follow-up data from records of 98 diabetic KTRs on SGLT2I, 41 on GLP- 1RA and 70 on standard-of-care medicines. Patients were more than 3 months post-transplant with a minimum estimated glomerular filtration rate (eGFR) of 25 ml/min/1.73 m2 . Demographic data were similar except for a slightly lower HbA1c in the control group and higher albuminuria in SGLT2i group. RESULTS HbA1c dropped significantly by .4% in both SGLT2i and GLP-1RA compared to .05% in the control group. A significant decrease in BMI by .32 in SGLT2i and .34 in GLP-1RA was observed compared to an increase by .015 in control group. A tendency for better eGFR in study groups was observed but was non-significant except for the SGLT2i group with an eGFR above 90 (p = .0135). The usual dip in eGFR was observed in the SGLT2i group at 1-3 months. Albuminuria was significantly reduced in both study groups. Adverse events were minimal with comparable safety in all groups. CONCLUSION The use of SGLT2i and GLP-1RA appears to be effective and safe in diabetic KTRs with good outcomes. Randomized control trials are required to confirm these findings and establish guidelines.

Abstract
INTRODUCTION Data regarding contrast-induced nephropathy (CIN) in kidney transplant (KT) recipients are scarce despite the distinct risk factors such as the use of immunosuppressive agents, sympathetic denervation, glomerular hyperfiltration, and high prevalence of the cardiovascular disease. This study aimed to determine the prevalence of CIN in KT recipients who received low-osmolality iodine-based contrast material (CM) for radiological assessment. METHODS Between 2010 and 2020, 79 of the 3180 KT recipients followed at Hamed Al-Essa organ transplant center received low-osmolality iodine-based contrast for radiological assessment for various indications. Preventive measures including holding metformin, intravenous hydration, sodium bicarbonate and N-acetylcysteine were given before contrast administration. CIN was defined as an increase in serum creatinine of 25% from the baseline within 72 hours. RESULTS The enrolled patients were divided into two groups: those who developed CIN (n = 7) and those with no increase in serum creatinine level (n = 72). The mean age of the patients was 52.1 ± 12.3 years; 44 of them were males, and the cause of end-stage kidney disease was mostly diabetic nephropathy. The pre-transplant demographics were comparable between the two groups. Fortyseven cases received contrast for coronary angiography, and 32 received it for a CT scan. The graft function deteriorated in group 1, but no significant difference was found between the two groups at the end of the study. CONCLUSION CIN is not uncommon in KT recipients receiving CM, especially with ischemic heart disease. Risk stratification, optimizing hemodynamics, and avoiding potential nephrotoxins are essential before performing CM-enhanced studies in KT recipients. DOI: 10.52547/ijkd.7165.

Abstract
Background: Honey has a lot of reputation because of its supposed medicinal properties. In this study, Hydroxymethylfurfural (HMF), sugars, and Fructose/Glucose ratio of honey in Bangladesh were assessed for adulteration and authenticity evaluation.
Methods: Seventy honey samples collected from different districts of Bangladesh were analyzed by High Performance Liquid Chromatography (HPLC) for HMF content and sugar profile. The samples were prepared by using Carrez I and Carrez II prior to injecting into HPLC. The samples were then filtered through syringe filter and taken in 1.5 ml vial for injecting into the HPLC system.
Results: HMF values were ranging from 1.41 mg/kg to 2,063.90 mg/kg. The Limit of Detection (LOD) and Limit of Quantification (LOQ) was found 0.10 mg/kg and 0.33 mg/kg with R2=0.9994. The average values of fructose, glucose, and sucrose were in the range of 14.75-52.44%, 8.19-42.63%, and 0.10-21.12%, respectively. From validation parameters, LOD values for fructose, glucose, and sucrose were 0.003, 0.008, and 0.004%, respectively; and LOQ values were 0.01, 0.028, and 0.015%, respectively with an excellent linearity with R2 for fructose=1.0, glucose=0.9999, and sucrose=1.0.
Conclusion: Some samples had higher HMF content which may be due to the storage time was increased and improper processing with high temperature or adulteration by High Fructose Corn Syrup (HFCS), sugar cane syrup, rice syrups or rice molasses. The sugar profiles showed that the most of honey samples were nectar honeys.

Abstract
Objective: The present study was conducted to investigate the potential effects of dietary supplemented propolis in two growing rabbit breeds on growth performance, immune response, blood parameters, carcass characteristics, and cecal microflora composition.Methods: A total of 90 growing rabbits aged 6 weeks from two breeds (V-line and Jabali) were randomly allocated to 3 dietary propolis experimental treatments. The experimental treatments consisted of a 2×3 factorial arrangement with two rabbit breeds and three levels of dietary propolis supplementation (0, 250 mg/kg, and 500 mg/kg). Each sub-treatment has 15 rabbits. The experimental period lasted six weeks.Results: There were no significant differences in growth performance and carcass characteristics due to propolis administration. Propolis supplementation at a high level significantly increased (linear; p<0.05) cellular-mediated immunity compared with the unsupplemented group. Furthermore, the rabbits receiving propolis exhibited a significant increase (linear and quadratic; p<0.03) in IgM immunoglobulins compared to the control. The current study provides further evidence that the dietary inclusion of propolis can significantly reduce pathogenic bacterial colonization in growing rabbits. The total count of microflora, E. coli, and Salmonella spp. was significantly lower (linear; p<0.01) in supplemented rabbit groups compared to the control group according to the microbiological analysis of cecal digesta. Based on breed effect, the results indicated that Jabali rabbits (local) performed better than V-line rabbits (foreign) in the majority of the studied traits.Conclusion: Dietary propolis is promising for further investigation into improving intestinal health and enhancing immunity in growing rabbits.

Abstract
The effectiveness of the inactivated BBIBP-CorV vaccine against severe COVID-19 outcomes (hospitalization, critical care admission and death due to COVID-19) and its long-term effectiveness have not been well characterized among the general population. We conducted a retrospective cohort study using electronic health records of 3,147,869 adults, of which 1,099,886 vaccinated individuals were matched, in a 1:1 ratio to 1,099,886 unvaccinated persons. A Cox-proportional hazard model with time varying coefficients was used to assess the vaccine effectiveness adjusting for age, sex, comorbidity, ethnicity, and the calendar month of entry into the study. Our analysis showed that the effectiveness was 79.6% (95% CI, 77.7 to 81.3) against hospitalization, 86% (95% CI, 82.2 to 89.0) against critical care admission, and 84.1% (95% CI, 70.8 to 91.3) against death due to COVID-19. The effectiveness against these severe outcomes declined over time indicating the need for booster doses to increase protection against severe COVID-19 outcomes.

Abstract
Abstract
BACKGROUND AND AIMS
Monoclonal antibodies inhibiting proprotein convertase subtilisin/Kexin type A(PCSK-9) have emerged as one of the new cholesterol-lowering agents. It is not evaluated among renal transplant recipients despite its favorable safety profile. We aimed to evaluate the safety and efficacy of evolocumab in reducing lipids and cardiovascular events among risky renal transplant recipients.
METHOD
About 195 kidney transplant recipients—with high cardiovascular risk (>20)—were enrolled in this randomized controlled study during the period between 6.2017 and 6.2018. Patients who received statin and evolocumab (140 mg/2 weeks, group 1, n = 97) while those who were maintained on statin alone comprised group 2 (n = 98). They were followed up for 24 months.
RESULTS
The two groups were comparable regarding their demographics (P > 0.05). Before enrollment in the study, post-transplant complications were comparable apart from a higher prevalence of NODAT in group 2 (P = 0.033). Smokers were significantly more prevalent in group 1. Basal graft function was significantly higher in group 1 despite equivalent regimen of immunosuppression in both groups (P > 0.05). Clinically two groups were comparable concerning cardiovascular events and both graft and patient outcomes (P > 0.05). Basal cholesterol was significantly higher in group 1 (5.5 versus 4.7, P < 0.001) which dropped significantly after 3 months (versus12 months in group 2) and thereafter (P = 0.031). We observed that triglycerides in the two groups were comparable (P > 0.05) till the end of the study.
CONCLUSION
Evolocumab is a promising add on lipid-lowering agent. In high risk renal transplant, earlier reduction of cholesterol was observed in the add-on evolocumab group but without significant positive cardiovascular impact.

Abstract
In the current study, a facile, rapid, and ecologically safe photosynthesis of gold nanoparticles (AuNPs) that remained stable for 3 months is reported to advocate the main aspects of green chemistry, such as safer solvents and auxiliaries, and the use of renewable feedstock. Zi-AuNPs were phytosynthesized by the aqueous extract of Ziziphus spina-christi leaves, and numerous techniques were employed for their characterization. The results demonstrated the successful phytofabrication of crystalline AuNPs with brownish-black color, spherical nanoparticles with a size between 0 and 10 nm, a plasmon peak at 540 nm, and a surface charge of -25.7 mV. Zi-AuNPs showed an effective photodegradation efficiency (81.14%) against malachite green and a good recycling capacity of 69.2% after five cycles of regeneration. The cytotoxicity test by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay signified a high anticancer efficiency for both Zi-AuNPs and Z. spina-christi extract against human breast cancer cells (MCF7 cell line) with IC50's of 48 and 40.25 μg/mL, respectively. Highly efficient antioxidant capabilities were proven with 2,2-diphenyl-1-picrylhydrazyl (DPPH) removal percentages of 67.5% for Zi-AuNPs and 92.34% for Z. spina-christi extract.

Abstract
This retrospective cohort study aims to review our 18-year experience with early hepatic artery thrombosis (e-HAT) following living-donor liver transplantation (LDLT), as well as to assess the feasibility, efficacy and potential risks of endovascular management of e-HAT in the first 48 hours (hrs) post-LDLT. Medical records of 730 patients who underwent LDLT were retrospectively reviewed. In all cases who had developed e-HAT, treatment modalities employed and their outcomes were evaluated. Thirty-one patients developed e-HAT(4.2%). Definite technical success and 1-year survival rates of surgical revascularization[11/31 cases(35.5%)] were 72.7% & 72.7%, whereas those of endovascular therapy[27/31 cases(87.1%)] were 70.4% & 59.3%, respectively. Endovascular therapy was carried out in the first 48hrs post-transplant in 9/31 cases(29%) [definite technical success:88.9%, 1-year survival:55.6%]. Four procedure-related complications were reported in 3 of those 9 cases(33.3%). In conclusion, post-LDLT e-HAT can be treated by surgical revascularization or endovascular therapy, with comparable results. Endovascular management of e-HAT in the first 48hrs post-LDLT appears to be feasible and effective, but is associated with a relatively higher risk of procedure-related complications, compared to surgical revascularization. Hence, it can be reserved as a second-line therapeutic option in certain situations where surgical revascularization is considered futile, potentially too complex, or potentially more risky.

Abstract
INTRODUCTION Plane warts, mostly found on the face, present a challenge to treat as most destructive methods can lead to unpleasant cosmetic outcome. Alternative therapeutic methods should be evaluated. The aim of this study is to evaluate the clinical efficacy and adverse effects of photodynamic therapy with methylene blue and intense pulsed light in comparison to candida antigen immunotherapy in the treatment of plane warts. METHODS The study included 39 patients with plane warts assigned into 3 groups. Group I received photodynamic therapy using methylene blue followed by IPL illumination, group II received immunotherapy using 0.1 ml of candida albicans antigen and group III received 0.1 ml saline as a control. RESULTS Complete response was detected in (46.1%) of patients in group I compared to (61.5%) in group II and no response in group III. CONCLUSION Candida antigen immunotherapy is superior to photodynamic therapy in plane warts treatment with absence of recurrence and comparable side effects in both groups.

Abstract
Background and Aims
Microalbuminuria is one of the early presentations of diabetic kidney disease that may progress to macroalbuminuria, progressive loss of glomerular filtration rate and eventually end stage renal disease. Early recognition and management of microalbuminuria can avert irreversible complications. Antihypertensive medications and antihyperlipidemic medications are medications that have been used to control diabetic nephropathy, but the reports of some side effects limited the usage of some of these drugs in diabetic patients. Pentoxifylline is an anti-inflammatory medication that have been experienced for clinical trials in diabetic patients with diabetic kidney disease. Effect of Pentoxifylline on albuminuria has been evaluated in several studies with different outcomes where a significant decrease in albuminuria in the Pentoxifylline group compared with placebo was the final conclusion. The aim of our study is the assessment of the value of Pentoxifylline addition in diabetic patients.
Method
Of 90 patients aged between 20 and 55 years old with a history of diabetes mellites type II for more than 5 years with normal serum creatinine and had a spot urinary albumin/creatinine ratio of > 300 mg/g on two consecutive measurements with HBA1C < 7% and lacking any history of glomerular disease, immunological, malignant nor cardiovascular disease in the previous 6 months nor using pentoxifylline for the past 3 month attending Ain Shams University clinics in Egypt from October 2017 to September 2018, 61 patients were eligible and randomly assigned in prospective, randomized, parallel-group, non-blind study after obtaining written informed consent from studied patients into 2 groups either the Pentoxifylline group (n = 30) receiving 400 mg thrice daily for 6 months or Ramipril group (n = 31) receiving 2.5 mg once daily on the same schedule. Blood samples and single first morning void urine samples were collected before breakfast after an 8–12 hours overnight fast. Plasma glucose, HbA1c, serum Creatinine, AST, ALT, and urinary protein / Creatinine levels were measured. All biochemical analyses were performed. Participants were followed up after 1, 3 and 6 months during the treatment period to evaluate the outcome
Results
Highly Statistically significant differences were noted as regard the reduction of the proteinuria levels at the same measurement points in both groups where the mean ranges of proteinuria in group 1 were found to be 2.2±1, 1.8±0.7, 1.4±0.6 mg\g at the start of the study, 3 and 6 month later respectively while in group 2 the mean range was found to be 2.6±1.2, 2±0.8, 1.6±0.7 mg\g with marked reduction of 20.6% after 3 month and 37.6% after 6 month from the start of the trial in group 1 in contrast to 20.7% and 40.2% respectively in group 2, also the effect of both drugs on the level of HbA1c has been studied in both group, in group 1 there was no reduction in the level of HbA1c after 6 month of drug administration in contrary to group 2 which showed a reduction of 4% where these results were found to be statistically significant in group 2 only. we also found statistically significant differences in both groups as regard the decline in eGFR throughout the trial duration which was 4% in group 1 and 6% in group 2.
Conclusion
We concluded that Pentoxifylline has a promising role as an antiproteinuric agent in comparison with ACEI from our statistical analysis of the study data with a more decline in eGFR throughout the trial duration in the study population using ACEI in comparison to Pentoxifylline. Due to restrictions of the study design these observations need further confirmation by prospective studies.

Abstract
Data regarding the lower diagnostic threshold for gastric graft-versus-host disease is lacking. The aim of this study was to review a cohort of gastric biopsies taken to evaluate for graft-versus-host disease, and to correlate histologic findings with clinical and endoscopic evidence of graft-versus-host disease as well as biopsy findings from other locations to define a lower diagnostic threshold for gastric graft-versus-host disease. Gastric biopsies were evaluated for the maximum number of apoptotic bodies per 10 contiguous gastric pits, presence of ≥1 apoptotic body per biopsy (NIH criteria), and presence of gastric pit dropout and/or ulceration. To evaluate histologic specificity, sixty gastric biopsies from non-stem cell transplant patients were selected as a control group. Clinical information was collected from chart review. The study group consisted of 65 gastric biopsies from 52 stem cell transplant patients. The mean apoptotic count per 10 contiguous gastric pits for stem cell transplant biopsies was 1.8 (range 0-8) and for control cases 1.0 (range 0-5). Nineteen stem cell transplant biopsies (29%) had ≥1 apoptotic body per biopsy and only a single case had >6 apoptotic bodies per 10 contiguous gastric pits. When the NIH guidelines were combined with presence of at least two apoptotic bodies per 10 contiguous gastric pits, this cutoff point was significantly associated with treatment for graft-versus-host disease (OR = 9.4, 95% CI = 1.7-176.7, p = 0.04) and evidence of extraintestinal graft-versus-host disease (OR = 3.2, 95% CI = 1.1-10.7, p = 0.04). The diagnostic specificity for our proposed cutoff value is 94%. We present criteria for the lower diagnostic threshold of gastric graft-versus-host disease, which uses a lower apoptotic cutoff value than has been utilized in colonic biopsies. Although sensitivity remains a challenge for gastric graft-versus-host disease biopsies, this newly proposed cutoff provides higher specificity than NIH guidelines alone and better correlates with clinical evidence of graft-versus-host disease.

Abstract
The sol-gel method was used to prepare perovskite type (Pb1-1.5x Lax□0.5x)TiO3 (PLT) ceramics with x = 0.21, 0.22, 0.23, 0.24, 0.25 in order to investigate their structural, optical, and dielectric properties. The crystallite compounds were obtained by calcinating the mixture of PbCO3, TiO2, and La2O3 at 1000 °C for different time periods. After 4 h annealing, PLT23 sample, approximately a very little secondary phases have been observed in the XRD spectrum of the PLT sample with 23% La content (PLT23). The presence of La dopants might have affected the tetragonality of the Lead titanate crystal structure. The PLT samples tolerance factor decreases from 0.991 as in x = 0.21 to 0.986 for x = 0.25. Hence, these structures tend, generally, to be in the perovskite phase as t ~ 1. In the doped ceramics, characteristic phase transitions were shifted to lower temperatures. The dielectric permittivity value showed the tendency of a slight increase with lanthanum addition and achieved its maximum εm (3649) at x = 0.23, then it decreases for higher concentrations of La. The samples' estimated average crystallite size ranged from 40 nm to 50 nm, the maximum crystallite size about (49.6 nm) at x = 0.23 La. The calculated bandgaps were 3.1, 3.26, 3.28, 3.08, and 3.12 for the PLT with 0.21, 0.22, 0.23,0.24 and 0.25% La, respectively. The Curie constant C was obtained as the slope of the curve of the inverse values of εr vs. temperature. The highest C value (5.2 × 105 K) was measured for the 23% La sample. The sample with 23% La content appears to be notably distinguished in its structural, optical, and dielectric characteristics compared with other samples.

Abstract
N-carboxyethylchitosan (CECS) was successfully prepared via Michael addition reaction of chitosan (CS) with acrylic acid in water. The structure of CECS was characterized by Fourier transform Infra-Red spectrometry (FT-IR), 1HNMR, elemental analysis, X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Differential scanning calorimetry (DSC). Antibacterial activity of CECS was evaluated against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) by using minimum inhibition concentration (MIC). The results showed that the prepared CECS soluble in water at wide range of pH values. In addition, it has amorphous character improve its chemical reactivity than CS itself, in addition it has been showed stronger antibacterial activity than chitosan itself due to the presence of both -COOH and -NH2 groups and the CECS shows higher antibacterial activity towards S. aureus than E. coli. Finally, the cytotoxicity of CECS has been evaluated through Cell viability assay, which confirm that CECS is non-toxic and tissue compatible like CS.

Abstract
CONTEXT.— Fatty liver disease is now one of the most commonly encountered entities in the practice of liver pathology. Distinguishing simple steatosis from steatohepatitis is critical because the latter requires follow-up because of long-term risks that include cirrhosis and hepatocellular carcinoma. An organized approach for evaluating liver biopsies with steatosis is recommended to capture all of the relevant features: (1) degree of steatosis, (2) presence or absence of ballooning degeneration, (3) lobular inflammation, and (4) fibrosis. Herein, we provide a stepwise approach that readers can use to evaluate liver biopsies with steatosis, including examples, pitfalls, differential diagnostic considerations, and suggested diagnostic phrasing. OBJECTIVE.— To provide a stepwise approach for the evaluation of liver biopsies showing significant steatosis (involving ≥5% of liver parenchyma). DATA SOURCES.— Biopsies demonstrating fatty liver disease encountered in our daily practice were examined as well as recent literature. CONCLUSIONS.— Effective evaluation of liver biopsies with steatosis requires careful histologic examination and correlation with clinical history, particularly regarding medications, nutrition status, and alcohol use. Examples of uniform reporting, including appropriate use of the nonalcoholic steatohepatitis Clinical Research Network Activity Score, are provided.

Abstract
OBJECTIVES Data on the management of chronic antibody-mediated rejection after kidney transplantation are limited. We aimed to assess the impact of treatment of biopsy-proven chronic active antibodymediated rejection with combined plasma exchange, intravenous immunoglobulin, and rituximab treatment versus intravenous immunoglobulin alone or conservative management on the evolution of renal function in renal transplant recipients. MATERIALS AND METHODS In this retrospective study, we compared patients diagnosed with chronic active antibody-mediated rejection who were treated with standard of care steroids, intravenous immunoglobulin, plasma exchange, and rituximab (n = 40) at our center versus those who received intravenous immunoglobulin only or just intensified maintenance immunosuppression (n = 28). All patients were followed for 12 months clinically and by laboratory tests for graft and patient outcomes. RESULTS The two groups were matched regarding mean recipient age (41.9 ± 15.4 vs 37.8 ± 15.5 y in patients with conservative versus combined treatment), recipient sex, mean body weight, and the cause of end-stage kidney disease. Most patients and their donors were males. Glomerulonephritis represented the most common cause of end-stage kidney disease in both groups followed by diabetic nephropathy. The type of induction and pretransplant comorbidities were not different between groups (P > .05) except for the significantly higher number of chronic hepatitis C infections in patients who received conservative treatment (P = .007). Mean serum creatinine values before and after treatment of chronic active antibodymediated rejection were comparable between groups (P > .05). Active treatment with heavier immunosuppression (rituximab and plasma exchange) was associated with posttreatment viral (cytomegalovirus and BK virus) and bacterial infections that necessitated more hospitalization (P > .05). However, graft and patient outcomes were significantly better in the active treatment group than in patients with conservative treatment (P = .002 and .028, respectively). CONCLUSIONS Combined treatment of chronic active antibody-mediated rejection with plasma exchange, intravenous immunoglobulin, and rituximab can significantly improve outcomes after renal transplant.

Abstract
A Series of ferrite samples Ni0.1 Cu0.2 Zn0.7-x Mgx Fe2O4 (where x = 0, 0.15, 0.25, 0.35, 0.45, 0.55 and 0.7) were synthesized using auto combustion flash method. The samples were annealed at 600 °c for 2 hours to eliminate the foreign phases of the constituent nitrate and internal stress. The purity of phase structure was confirmed by x-ray diffraction. Some structural and microstructural parameters like porosity, x-ray density, crystallite size and lattice constant were deduced from x-ray. Scanning electron microscope (SEM) analysis reveals that the grains are separated by pores in all samples and the average grain size decreases with increasing Mg content. Magnetic properties such as coercivity (Hc), saturation magnetization (Ms) and retentivity (Mr) were measured from M-H loops. The magnetization curves were characterized by low coercivity indicating that our samples are soft magnetic material. Both saturation magnetization and coercivity increase by increasing Mg ions where Ms reaches maximum value at x = 0.35 then decrease for higher Mg content.

Abstract
BACKGROUND Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. METHODS This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. FINDINGS Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05-2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001). INTERPRETATION Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.

Abstract
Objectives To investigate concussion injury rates, the likelihood of sustaining concussion relative to the number of rugby union matches and the risk of subsequent injury following concussion. Methods A four-season (2012/2013–2015/2016) prospective cohort study of injuries in professional level (club and international) rugby union. Incidence (injuries/1000 player-match-hours), severity (days lost per injury) and number of professional matches conferring a large risk of concussion were determined. The risk of injury following concussion was assessed using a survival model. Results Concussion incidence increased from 7.9 (95% CI 5.1 to 11.7) to 21.5 injuries/1000 player-match-hours (95% CI 16.4 to 27.6) over the four seasons for combined club and international rugby union. Concussion severity was unchanged over time (median: 9 days). Players were at a greater risk of sustaining a concussion than not after an exposure of 25 matches (95% CI 19 to 32). Injury risk (any injury) was 38% greater (HR 1.38; 95% CI 1.21 to 1.56) following concussion than after a non-concussive injury. Injuries to the head and neck (HR 1.34; 95% CI 1.06 to 1.70), upper limb (HR 1.59; 95% CI 1.19 to 2.12), pelvic region (HR 2.07; 95% CI 1.18 to 3.65) and the lower limb (HR 1.60; 95% CI 1.21 to 2.10) were more likely following concussion than after a non-concussive injury. Conclusion Concussion incidence increased, while severity remained unchanged, during the 4 years of this study. Playing more than 25 matches in the 2015/2016 season meant that sustaining concussion was more likely than not sustaining concussion. The 38% greater injury risk after concussive injury (compared with non-concussive injury) suggests return to play protocols warrant investigation.
