The differential diagnosis of Helicobacter pylori negative gastritis
Abstract
Gastric biopsies are often submitted with as clinical question Helicobacter pylori (HP) infection. Regularly, the morphology suggests a HP infection but the organism is not detected in special stains. This review presents a practical approach to deal with such biopsies. The first step is to exclude a false negative result of the search for HP, by ensuring that both antral and oxyntic mucosa are present, by the use of sensitive stains, identification of marked reactive changes, such as intestinal, pseudo-pyloric, pancreatic metaplasia that may suggest a diagnosis of (HP associated or autoimmune) atrophic gastritis, and finally identification of signs of the use of proton pump inhibitors (PPI) as in such biopsies, HP may sometimes be found only within parietal cells. The differential diagnosis should include lymphocytic gastritis, other diseases affecting the stomach, such as inflammatory bowel disease (IBD), vasculitis, granulomatous disease, viral infection, such as cytomegalovirus (CMV) or more rarely Epstein-Barr virus (EBV) infection, or other bacterial infections, such as Enterococcus and Treponema pallidum. Clinical input may be required to ensure the patient is not taking medication that may cause gastritis, such as antibiotics used for HP eradication or common medications that cause a form of gastropathy. When these have been excluded, a known cause has not been found and in such a case, the term idiopathic focal/diffuse gastritis can be used.

Association Between Type 2 Diabetes Mellitus and Hearing Loss Among Patients in a Coastal City of South India
Abstract
Diabetes mellitus (DM) is a metabolic culprit known to perpetuate several disease processes. The relationship between hearing loss (HL) and type 2 DM (T2DM) remains unclear despite the vast volume of research devoted to this topic. We conducted this study with the aim to evaluate HL among T2DM patients and to assess the relationship between severity of HL, glycosylated hemoglobin (HbA1c) levels and duration of T2DM. Design: a time bound descriptive crosssectional study. Setting: tertiary care hospital of South India. Subjects: subjects with T2DM, aged from 40 to 60 years (excluding hypertension, chronic noise exposure and history of smoking or ototoxicity) were included. Methods: Non-random convenience sampling. Details were gathered using a self-administered, semistructured questionnaire and the hearing was assessed by pure tone audiometry. Data was analysed using SPSS. A large proportion of the sampled population had audiological assessments suggestive of SensoriNeural HL (SNHL). 90.2% had a bilateral distribution of HL; however, only 39% of patients reported having any associated ear complaints. No statistically significant associations were obtained between severity of HL, glycaemic control, duration of diabetes or gender. Bilateral SNHL is a complication associated with T2DM. Duration and glycaemic control are independent variables and do not statistically influence the severity of HL. However, this study demonstrated that many patients with SNHL had no symptoms and also lacked awareness of HL in DM. Therefore routine assessment of hearing should be considered in the diabetic population.

Human Vestibulo-Ocular Reflex Adaptation Training: Time Beats Quantity
Abstract
The vestibulo-ocular reflex (VOR) is the main gaze stabilising system during rapid head movements. The VOR is highly plastic and its gain (eye/head velocity) can be increased via training that induces an incrementally increasing retinal image slip error signal to drive VOR adaptation. Using the unilateral incremental VOR adaptation technique and horizontal active head impulses as the vestibular stimulus, we sought to determine the factors important for VOR adaptation including: the total training time, ratio and number of head impulses to each side (adapting and non-adapting sides; the adapting side was pseudo-randomised left or right) and exposure time to the visual target during each head impulse. We tested 11 normal subjects, each over 5 separate sessions and training protocols. The basic training protocol (protocol one) consisted of unilateral incremental VOR adaptation training lasting 15 min with the ratio of head impulses to each side 1:1. Each protocol varied from the basic. For protocol two, the ratio of impulses were in favour of the adapting side by 2:1. For protocol three, all head impulses were towards the adapting side and the training only lasted 7.5 min. For protocol four, all impulses were towards the adapting side and lasted 15 min. For protocol five, all head impulses were to the adapting side and the exposure time to the visual target during each impulse was doubled. We measured the active and passive VOR gains before and after the training. Albeit with small sample size, our data suggest that the total training time and the visual target exposure time for each head impulse affected adaptation, whereas the total number and repetition rate of head impulses did not. These data have implications for vestibular rehabilitation, suggesting that quality and duration of VOR adaptation exercises are more important than rapid repetition of exercises.

Effect of atrazine on growth and production of AFB 1 in Aspergillus section Flavi strains isolated from maize soils
Abstract
Atrazine is one of the most frequently used herbicides in Argentina for controlling broadleaf weeds and annual grasses. Currently, there is limited information on the impact of triazine herbicides on mycotoxin production and growth parameters of toxigenic fungi in maize. The objective of this study was to evaluate the effect of different concentrations of atrazine on the lag phase prior to growth, the growth rate, and on production of aflatoxin B1 (AFB1) of Aspergillus flavus and Aspergillus parasiticus strains, on maize meal extract agar (MMEA) under different water activities (aW) and temperatures. A commercial formulation of atrazine was added to MMEA medium at 0, 5, 10, 50, or 100 mmol/l, adjusted to 0.98, 0.95, and 0.93 aW, and incubated at 28 °C and 37 °C for 21 days. AFB1 was determined by HPLC after 7, 14, and 21 days of incubation. In the control treatments, a significant increase in the time prior to growth was observed and as the aW decreased, at both temperatures, the growth rate of the strains also decreased. A significant increase in growth rate was observed as the concentration of atrazine in the medium increased, for all aW levels tested. The optimal conditions for the accumulation of AFB1 in the control treatments were 0.98 aW and 28 °C, after 7 days of incubation. As the concentration of herbicide increased, AFB1 production also increased (P < 0.05). These results add to the knowledge about consequences with regard to aflatoxin production of the use of excessive atrazine doses in extensive maize culture.

Short-term evaluation of photobiomodulation therapy on the proliferation and undifferentiated status of dental pulp stem cells
Abstract
The aim of this in vitro study was to analyze the effect of photobiomodulation therapy (PBMT) on the proliferation and undifferentiating status of stem cell from human exfoliated deciduous teeth (SHEDs). PBMT was carried out with an aluminum gallium indium phosphide (InGaAlP) diode laser in contact and punctual mode (continuous wave, 660 nm, 20 mW, 0.028 cm2, and average energy densities of 1 (1 s), 3 (4 s), 5 (7 s), 10 (14 s), 15 (21 s), or 20 (28 s) J/cm2 per point). The immunoprofile of the SHEDs was analyzed using flow cytometry. Cell proliferation was assessed by the MTT reduction assay. Gene expressions of mesenchymal stem cell markers (OCT4, Nestin, CD90, and CD105) were assessed by RT-qPCR 48 h after PBMT. Data were compared by analysis of variance (ANOVA) and Tukey's test (p ≤ 0.05). Cells cultured under nutritional deficit and treated with PBMT at 5 J/cm2 presented similar cell growth than those of positive control group. Cell growth was significantly higher than those of other groups. Mesenchymal stem cell gene markers were still expressed after PBMT at 5 J/cm2. In a short-term analysis, PBMT increases the number of stem cells with no interference in the undifferentiated state of the irradiated cells, which opens wide possibilities for application in tissue regeneration.

Management of Long-Standing Flaccid Facial Palsy
Chronic flaccid facial paralysis (FFP>2 years) may be approached with static and dynamic techniques. An horizontal zonal assessment evaluates the upper, middle, and lower thirds of the face. Surgery is tailored to an individual's deficits, goals, and health status. While dynamic reanimation is the gold standard for rehabilitation, there are cases in which static approaches are more appropriate or may be used as an adjunct to dynamic techniques. This article focuses on the surgical management of FFP primarily using static approaches to the individual zones of the face to create resting symmetry.

TRPM2 modulates neutrophil attraction to murine tumor cells by regulating CXCL2 expression
Abstract
In recent years, immune cells were shown to play critical roles in tumor growth and metastatic progression. In this context, neutrophils were shown to possess both pro- and anti-tumor properties. To exert their anti-tumor effect, neutrophils need to migrate towards, and form physical contact with tumor cells. Neutrophils secrete H2O2 in a contact-dependent mechanism, thereby inducing a lethal Ca2+ influx via the activation of the H2O2-dependent TRPM2 Ca2+ channel. Here, we explored the mechanism regulating neutrophil chemoattraction to tumor cells. Interestingly, we found that TRPM2 plays a role in this context as well, since it regulates the expression of potent neutrophil chemoattractants. Consequently, cells expressing reduced levels of TRPM2 are not approached by neutrophils. Together, these observations demonstrate how tumor cells expressing reduced levels of TRPM2 evade neutrophil cytotoxicity in two interrelated mechanisms—downregulation of neutrophil chemoattractants and blocking of the apoptotic Ca2+-dependent cascade. These observations demonstrate a critical role for TRPM2 in neutrophil-mediated immunosurveillance and identify cells expressing low levels of TRPM2, as a potential target for cancer therapy.

Molecular Expression of Mg2+ regulator TRPM7 and CNNM4 in rat odontoblasts
Publication date: Available online 23 September 2018
Source: Archives of Oral Biology
Author(s): Jonghwa Won, Ji Hyun Kim, Seog Bae Oh
Abstract
Objective
Magnesium, the second most abundant cation in cellular fluid, is critical for mineralization of hard tissues. Among the molecules involved in cellular Mg2+ homeostasis, functional impairment of Mg2+ permeable ion channel TRPM7 or Mg2+ transporter CNNM4 have been found to result in severe hypomineralization of the enamel and dentin. However, molecular expressions of TRPM7, CNNM4 and their respective homologues have not been fully investigated in adult odontoblasts.
Design
Expressions of TRPM6, TRPM7, CNNM1, CNNM2, CNNM3, CNNM4 were screened in acutely dissociated rat odontoblasts by single cell RT-PCR. Among these candidates, expression levels of TRPM7 and CNNM4 were compared along the odontoblast layer by immunohistochemical analysis. Finally, the coexpression pattern of TRPM7 and CNNM4 in subcellular regions was examined by immunocytochemical analysis.
Results
ScRT-PCR revealed high expression rate of TRPM7 and CNNM4 in odontoblasts, with CNNM4 detected almost exclusively in TRPM7-positive odontoblasts. However, CNNM2 and CNNM3 were detected in only a small population of odontoblasts, and TRPM6 and CNNM1 were not detected even in the pulp tissue. Immunohistochemical analysis revealed higher CNNM4 expression in the apical odontoblast layer than the coronal area, in contrast to the ubiquitous expression of TRPM7. Lastly, immunocytochemical analysis revealed colocalization of CNNM4 with TRPM7 in the odontoblastic process.
Conclusions
CNNM4 and TRPM7 may serve as main Mg2+ regulators in odontoblasts, possibly with selective involvement of CNNM4 in apical dentin formation or mineralization. Colocalization of TRPM7 and CNNM4 in the odontoblastic process suggest functional coupling of these two molecules to maintain Mg2+ homeostasis.

Null Cell Adenoma of the Pituitary: Pseudo-rosettes Say It Best When Immunohistochemistry Says Nothing At All!
Abstract
Null cell adenoma is composed of adenohypophyseal cells that show no evidence of any specific cell type differentiation by immunohistochemistry or transcription factors like pituitary-specific positive transcription factor 1 and steroidogenic factor 1. Though rare, pituitary ependymoma and germinoma are also known to occur at sellar region and in such instances, it is challenging to differentiate them from a pituitary null cell adenoma featuring papillary architecture and perivascular pseudo-rosettes. We describe a case of an elderly diabetic lady presenting with headache and blurring of vision for past 3 months due to a sellar tumour. The histology was diagnostically challenging with notable presence of numerous perivascular pseudo-rosettes and negative immunoreactivity for all pituitary hormones. The differential diagnosis and importance of ancillary techniques is discussed.

Analytic and clinical validity of thyroid nodule mutational profiling using droplet digital polymerase chain reaction
Abstract
Background
Recent guidelines for the management of thyroid nodules incorporate mutation testing as an adjunct for surgical decision-making, however current tests are costly with limited accuracy. Droplet digital PCR (ddPCR) is an ultrasensitive method of nucleic acid detection that is particularly useful for identifying gene mutations. This study aimed to assess the analytic and clinical validity of RAS and BRAF ddPCR mutational testing as a diagnostic tool for thyroid fine needle aspirate biopsy (FNAB).
Methods
Patients with thyroid nodules meeting indication for FNAB were prospectively enrolled from March 2015 to September 2017. In addition to clinical protocol, an additional FNAB was obtained for ddPCR. Optimized ddPCR probes were used to detect mutations including HRASG12 V, HRASQ61K, HRASQ61R, NRASQ61R, NRASQ61K and BRAFV600E. The diagnostic performance of BRAF and RAS mutations was assessed individually or in combination with Bethesda classification against final surgical pathology.
Results
A total of 208 patients underwent FNAB and mutational testing with the following Bethesda cytologic classification: 26.9% non-diagnostic, 55.2% benign, 5.3% FLUS/AUS, 2.9% FN/SPN, 2.4% SFM and 7.2% malignant. Adequate RNA was obtained from 91.3% (190) FNABs from which mutations were identified in 21.1% of HRAS, 11.5% of NRAS and 7.4% of BRAF. Malignant cytology or BRAFV600E was 100% specific for malignancy. Combining cytology with ddPCR BRAF600E mutations testing increased the sensitivity of Bethesda classification from 41.7 to 75%. Combined BRAFV600E and Bethesda results had a positive predictive value (PPV) of 100% and negative predictive value (NPV) of 89.7% for thyroid malignancy in our cohort.
Conclusions
DdPCR offers a novel and ultrasensitive method of detecting RAS and BRAF mutations from thyroid FNABs. BRAFV600E mutation testing by ddPCR may serve as a useful adjunct to increase sensitivity and specificity of thyroid FNAB.

Quality of occlusal outcome following space closure in cases of lower second premolar aplasia using lingual orthodontic molar mesialization without maxillary counterbalancing extraction
Abstract
Background
Controlled space closure in cases of isolated lower second premolar aplasia (ILSPA) without maxillary counterbalancing extraction is challenging. Anterior anchorage loss may occur during space closure resulting in compromised occlusal results in terms of an absence of proper canine guidance during laterotrusive mandible movements.
In order to evaluate the effectiveness of Herbst telescope anchorage in combination with double-cable, pull mechanics and a completely customized lingual appliance for orthodontic space management in cases of ILSPA, we tested the null hypothesis that there is a significant deterioration in the sagittal canine relationship towards an Angle-Class-II occlusion expressed as a loss of anterior anchorage following space closure with molar mesialization.
Methods
Twenty-five consecutively de-bonded subjects (female / male 17 / 8; aged at T0 (start of MB Tx) 12.3 to 20.6 years; mean age 15.0 / SD 1.7 years) were included in this retrospective analysis using the inclusion criteria of least of one lower second premolar aplasia; completed treatment with a totally customized lingual appliance (CCLA) in combination with Herbst telescopes. Exclusion criteria were the absence of counterbalancing maxillary extractions, as well as additional tooth aplasia other than lower second premolars. A total of 33 single, lower premolar aplasia space closures (right / left sided 17 / 16) were assessed using plaster casts and intra-oral photographs scaled to the plaster casts, at bonding (T0), Herbst insertion (T1), following gap closure (T2) and de-bonding (T3). Parallelism of roots was controlled by panoramic x-rays at T3.
Results
The mean aplasia space at T0 was 7.5 mm (SD 2.6). Complete space closure was achieved in all 33 situations. The null hypothesis was rejected. There was a significant improvement in the initial canine relationships (mean 3.5 mm distal occlusion at T0) to a mean 0.1 mm at T3. When evaluated against the individual treatment plan, the following amounts of planned improvements were achieved: space closure 100%, canine relationship 97.5%, overjet 93.9%, overbite 96.4%, parallel roots in space closure site 93.9%.
Conclusion
Herbst telescope anchorage in combination with double-cable pull mechanics and a CCLA for orthodontic space closure can deliver predictable, high-quality treatment results.

Primary Laryngeal Tuberculosis: A Series of 15 Cases
Abstract
Tuberculosis usually involves the lungs, but can also involve various other organs. Extra pulmonary tuberculosis is very rarely confined to the larynx in the absence of an associated pulmonary lesion. In this retrospective study, clinicopathological characteristics of patients with final diagnosis of laryngeal tuberculosis (LTB) were reviewed. The diagnosis of LTB was based on: (1) the existence of chronic granulomatous inflammation with caseous necrosis in the histopathology of laryngeal lesions or (2) the presence of laryngeal lesions with atypical histopathology (chronic granulomatous inflammation) which had a complete response to anti-tuberculosis therapy. Fifteen cases with a diagnosis of LTB were collected. The patients' age ranged between 24 and 75 years with a mean of 49 years. On laryngoscopy, 66.6% of cases (10/15) had an ulceroproliferative lesion while the remaining 33.3% of cases (5/15) had an exophytic growth. The pathology of laryngeal lesions revealed chronic granulomatous inflammation with caseous necrosis in nine cases and chronic granulomatous inflammation without necrosis in six cases. Nine out of 15 cases (60%) showed presence of acid-fast bacilli on Ziehl–Neelsen stain. Any evidence of pulmonary tuberculosis was ruled out by chest X-ray findings. The response to anti-tuberculosis therapy was desirable in all patients. Since the introduction of anti-tuberculous therapy, the incidence of LTB has declined. However, with the incidence of TB increasing, the overall incidence of laryngeal involvement may be on the rise. This study highlights the importance to consider the rare possibility of LTB in the presence of non-specific clinical and laryngoscopic signs and to confirm this by histological examination.

Effects of topical applications of porcine acellular urinary bladder matrix and Centella asiatica extract on oral wound healing in a rat model
Abstract
Objectives
To evaluate the effects of topical applications of porcine acellular urinary bladder matrix (AUBM) and Centella asiatica extract (CAE) on the healing of tongue wounds in a rat model.
Materials and methods
Wounds were made in the tongue using a punch tool in 64 male Sprague-Dawley rats, randomized into four groups (n = 16 per group): group 1 (control), group 2 (CAE), group 3 (AUBM mixed with orabase), and group 4 (orabase). No product was applied in group 1 and groups 2–4 received three daily topical applications. The animals were weighed on day 0 and at the time of euthanasia. Four rats in each group were euthanized at days 2, 7, 14, and 21 and the tongues were processed for: macroscopic morphometric analysis, myeloperoxidase (MPO) and malondialdehyde (MDA) levels, histological wound repair (degree of reepithelialization and inflammation), and CD31 positivity.
Results
The animals' weight gain, histological wound repair, and CD31 positivity from greatest to least were: AUBM > CAE > orabase > control. Percentage of tongue occupied by wound, MPO, and MPA levels from least to greatest were: AUBM < CAE < orabase < control, whereby the AUBM group showed significant differences (p ≤ 0.05) in comparison with the other groups on days 2, 7, 14, and 21 for percentage of tongue occupied by wound and MDA and on days 7, 14, and 21 for MPO.
Conclusions
CAE is effective for oral tissue regeneration, while AUBM is an even more potent means of oral mucosa regeneration.
Clinical relevance
AUBM may be beneficial to patients with oral wounds; this finding requires further clinical and laboratory investigation.

The effect of the volume of supra-inguinal injected solution on the spread of the injectate under the fascia iliaca: a preliminary study
Abstract
The fascia iliaca compartment is the compartment confined by the fascia iliaca (FI) and a muscular layer formed by the iliac- and psoas muscle. This compartment creates a virtual tunnel that contains the femoral nerve (FN), the obturator nerve (ON), and the lateral femoral cutaneous nerve (LFCN) of the lumbar plexus. In this pilot study, we aimed to determine the suggested volume needed to reach the three target nerves of the lumbar plexus (FN, ON, and LFCN) with a single-injection ultrasound-guided supra-inguinal fascia iliaca compartment (S-FICB). A computer tomography (CT scan)-guided step-up/step-down sequence was used to determine the suggested injection volume to target all three nerves. Subsequently, an anatomist blinded for the injected volume and CT findings, dissected the cadavers, and evaluated the spread of dye underneath the fascia iliaca. In total, seven pelvic areas of four cadavers were evaluated on CT scan and dissected. Distribution of dye underneath the FI in relation to the FN, ON, and the LFCN was recorded in all dissected cadavers. Combining CT and dissection findings, the suggested volume to reach the FN, ON, and LFCN with an S-FICB was 40 mL.

Role of Concha Bullosa in Chronic Rhinosinusitis
Abstract
Concha bullosa is one of the most common anatomical variant found in the patients of chronic rhinosinusitis. To study the role of concha bullosa in patients of chronic rhinosinusitis a prospective cross sectional study was done comprising of 60 patients who were having symptoms of sinusitis for more than 12 weeks. These were evaluated with the help of nasal endoscope and CT scan. DNS and concha bullosa are the most common anatomical variant seen in the patients of chronic rhinosinusitis with percentage being 88.3% and 76.6% respectively. Patients with deviated nasal septum and large concha bullosa (bulbous and extensive) were associated with higher incidence of ostiomeatal complex obstruction. There seems a strong relationship between unilateral concha bullosa and contralateral deviated nasal septum in development of chronic rhinosinusitis. (1) To find out the percentage and role of concha bullosa in patients of chronic rhinosinusitis. (2) To screen the patients of chronic rhinosinusitis for concha bullosa. (3) To do the nasal endoscopy and CT scan of the screened patients. Study design: cross sectional study. Sample size: 60. Inclusion criteria: all patients of chronic rhinosinusitis. Exclusion criteria: patients with previous sinus surgeries, malignancy and acute cases of chronic rhinosinusitis.

Niedrig dosierte prophylaktische orale Therapie mit Isotretinoin über 18 Jahre bei einer Patientin mit Epidermodysplasia verruciformis und zahlreichen Plattenepithelkarzinomen
Zusammenfassung
Epidermodysplasia verruciformis (auch Lewandowsky-Lutz-Dysplasie) ist eine extrem seltene autosomal-rezessive Genodermatose, bei der eine ungewöhnlich hohe Empfindlichkeit der Haut gegenüber humanen Papillomviren vorliegt. Die Erkrankung ist mit einem hohen Risiko für die Entwicklung von nichtmelanozytären Hauttumoren verbunden. Eine Behandlung mittels keratolytischen Retinoiden gilt derzeit als die effektivste Therapie. Retinoide haben ein breites Wirkungsspektrum und hemmen das Wachstum von Plattenepithelkarzinomen und anderen bösartigen Tumoren. Wir berichten über eine 81-jährige Patientin, die aufgrund einer Epidermodysplasia verruciformis (Nachweis von HPV 9 und HPV 57) mit der raschen Entwicklung zahlreicher kutaner Karzinome seit ca. 18 Jahren eine prophylaktische orale Therapie mit Isotretinoin in einer Dosis von 1,0–0,33 mg/kg Körpergewicht täglich erhält. Im Verlauf zeigte sich eine starke Reduktion der Inzidenz, des Größenwachstums und der Invasionsneigung von weiteren Karzinomen der Haut, sodass wir im vorliegenden Fall einen protektiven Effekt der Retinoidgabe auf die Aktivität der Hautkrebserkrankung postulieren.

Primary Laryngeal Tuberculosis: A Series of 15 Cases
Abstract
Tuberculosis usually involves the lungs, but can also involve various other organs. Extra pulmonary tuberculosis is very rarely confined to the larynx in the absence of an associated pulmonary lesion. In this retrospective study, clinicopathological characteristics of patients with final diagnosis of laryngeal tuberculosis (LTB) were reviewed. The diagnosis of LTB was based on: (1) the existence of chronic granulomatous inflammation with caseous necrosis in the histopathology of laryngeal lesions or (2) the presence of laryngeal lesions with atypical histopathology (chronic granulomatous inflammation) which had a complete response to anti-tuberculosis therapy. Fifteen cases with a diagnosis of LTB were collected. The patients' age ranged between 24 and 75 years with a mean of 49 years. On laryngoscopy, 66.6% of cases (10/15) had an ulceroproliferative lesion while the remaining 33.3% of cases (5/15) had an exophytic growth. The pathology of laryngeal lesions revealed chronic granulomatous inflammation with caseous necrosis in nine cases and chronic granulomatous inflammation without necrosis in six cases. Nine out of 15 cases (60%) showed presence of acid-fast bacilli on Ziehl–Neelsen stain. Any evidence of pulmonary tuberculosis was ruled out by chest X-ray findings. The response to anti-tuberculosis therapy was desirable in all patients. Since the introduction of anti-tuberculous therapy, the incidence of LTB has declined. However, with the incidence of TB increasing, the overall incidence of laryngeal involvement may be on the rise. This study highlights the importance to consider the rare possibility of LTB in the presence of non-specific clinical and laryngoscopic signs and to confirm this by histological examination.

A Randomized Study of Quantiferon-CMV-Directed Versus Fixed Duration Valganciclovir Prophylaxis to Reduce Late CMV Following Lung Transplantation
Background We provide the results of the first interventional study of CMV-specific immune monitoring to direct the length of antiviral prophylaxis in lung transplantation (LTx). Methods Patients (n = 118) at risk of CMV infection were randomized 1:2 to either 5 months or variable length valganciclovir prophylaxis (5-11 months post-LTx), as determined by the QuantiFERON (QFN)-CMV assay. Patients with a negative QFN-CMV assay ( 600 copies/ml) within the blood was significantly reduced in patients with a positive QFN-CMV assay compared to those without protective immunity (13% vs 67%, p = 0.0003), as was the incidence of severe viremia (>10,000 copies/ml) (3% vs 50%, p

Effect of the Selective NLRP3 Inflammasome Inhibitor mcc950 on Transplantation Outcome in a Pig Liver Transplantation Model with Organs from Donors after Cardiac Death Preserved by Hypothermic Machine Perfusion
Background We investigated whether the outcome of organs from donors after cardiac death (DCD) can be improved by the addition of mcc950 to the perfusate of the hypothermia machine perfusion (HMP) system and intravenous mcc950 injection after transplantation in a pig liver transplantation model. Methods Thirty-six healthy Bama mini pigs randomized into 3 groups. All the DCD livers were preserved in an HMP system after 2 h of simple cold storage (SCS).In HMP-Postop group, mcc950 was added to the perfusate; in the control group and Postop group, the perfusate was normal LPS. After transplantation, the pigs in the Postop group and HMP-Postop group were intravenously administered 3 mg/kg mcc950, at the time of reperfusion and on day 2 and day 3 after transplantation. During the 3-day follow-up period, general operative characteristics, and serological markers and histological features related to ischemia reperfusion injury were examined. Results The HMP-Postop group suffer the lightest ischemia reperfusion injury(IRI),and functioned best after transplantation. Model for the Early Allograft Function Score (MEAF, predictor of long-term survival), degree of injury in the hepatocytes and rate of apoptosis was lowest in the HMP-Postop group. Further, in the HMP-Postop group, the NLRP3 inflammasome pathway activation was lowest, and the level of IL-1β was lowest. Postop group functioned better than control group, but not comparable with HMP-Postop group. Conclusions The outcome of DCD organs can be improved by the addition of mcc950 to the perfusate of the HMP system and intravenous injection of mcc950 after transplantation. *Corresponding Author: Dr. Yong-Feng Liu, MD, First Affiliated Hospital, China Medical University, 155 Nanjing Street, Shenyang , Liaoning Province 110000, The People's Republic of China.

Recent History of Serious Fall Injuries and Posttransplant Outcomes among U.S. Kidney Transplant Recipients
Background Serious fall injuries are associated with poor outcomes among dialysis patients, but whether these associations hold in patients with a history of serious fall injury before kidney transplantation is unknown. Methods In national administrative data, 22 474 U.S. adults receiving a first kidney transplant in 2011-2014 with at least 1 year of follow-up prior to transplant were identified. Serious fall injuries in the year prior to transplant were identified using diagnostic codes for falls and simultaneous fractures, dislocations, or head trauma in inpatient or outpatient claims. We used multivariable Cox proportional hazards models to estimate associations of incident posttransplant outcomes with serious fall injury in the year prior to transplant. Results A total of 620 recipients (2.8%) had serious fall injuries prior to transplant and were more likely to be white, female, and have more comorbid conditions than those without a fall injury. While posttransplant recipient survival did not differ by recent serious fall injuries (HR=1.03; 95% CI 0.78-1.36), these injuries were associated with 33% higher rates of graft failure (HR=1.33; 95% CI 1.03-1.72). Patients with serious fall injuries spent 12.1% of posttransplant follow-up hospitalized, a 3.3-fold higher rate than those without a fall, and had nearly 2-fold higher rates of skilled nursing facility utilization (HR=1.98; 95% CI 1.52-2.57). Conclusions Serious fall injuries are independently associated with significantly greater resource requirements and lower graft survival. Further study is needed to delineate the relationship between falls and adverse outcomes in transplant and reduce the incidence and deleterious effects of these events.

Novel Therapeutic Approaches to Allosensitization and Antibody-Medicated Rejection
Modification of pathogenic antibodies for autoimmune diseases illuminated the biologic relevance of B cells, plasma cells and pathogenic antibodies in autoimmunity. They have also rejuvenated interest in how B cells mediate multiple effector functions that include antibody production, antigen presentation to T cells, costimulation and the production of immune stimulating and immune modulatory cytokines. Repurposing these drugs from autoimmunity and cancer immunotherapy has yielded important advancements in the care of ABMR patients and novel drug development aimed at HLA desensitization have recently emerged. We now stand on an important threshold that promises many advances in the care of our allosensitized patients. We hope these initial advances will encourage basic scientist, clinical investigators, industry, National Institutes of Health (NIH), our academic societies and the FDA to continue support of these important objectives. These advances clearly have implications for sensitized patients receiving solid organ transplants and ABMR treatment. Modification of alloimmunity and alloantibodies will also have relevance to xenotransplantation where the xenoantibodies present a formidable obstacle to advancement of this important therapy. Working together, we can advance transplant therapeutics where biologic agents are likely to play novel and important roles. Here we discuss novel drugs emerging in this area.

Building Kidney Exchange Programmes in Europe – An Overview of Exchange Practice and Activities
Background Considerable differences exist among the living donor Kidney Exchange Programmes (KEPs) that are in use and being built in Europe, contributing to a variation in the number of living donor transplants [6]. Efforts of European KEPs to exchange (best) practices and share approaches to address challenges have, however, been limited. Methods Experts from 23 European countries, collaborating on the ENCKEP COST Action, developed a questionnaire to collect detailed information on the functioning of all existing KEPs in Europe, as well as their opportunities and challenges. Following a comparative analysis, results were synthesised and interpreted by the same experts. Results The practices, opportunities and challenges reported by 17 European countries reveal that some of the 10 operating programmes are mature, while others are in earlier stages of development. Over 1300 transplants were performed through existing KEPs up to the end of 2016, providing approximately 8% of their countries' living kidney donations in 2015. All countries report challenges to either initiating KEPs or increasing volumes. Some challenges are shared, whilst others differ because of differences in context (eg, country size, effectiveness of deceased donor programme) and ethical and legal considerations (eg, regarding living donation as such, nonrelated donors, and altruistic donation). Transnational initiatives have started in Central Europe, Scandinavia, and Southern Europe. Conclusions Exchange of best practices and shared advancement of national programmes to address existing challenges, aided by transnational exchanges, may substantially improve access to the most (cost) effective treatment for the increasing number of patients suffering from kidney disease.
