Abstract
Since the first transcatheter aortic valve implantation (TAVI) in 2002, the paradigm for the treatment of severe aortic stenosis has changed. In the recent past, medical therapy with or without balloon aortic valvuloplasty was the only option for inoperable patients but now, TAVI has become the treatment of choice for these patients and the preferred alternative for high-risk operable patients. Surgical aortic valve replacement (SAVR) currently remains the gold standard for patients at low operative risk. As randomized trials have demonstrated comparable (or better results with TAVI) between TAVI and SAVR in the high-risk population, there is now a clear trend towards performing TAVI even in intermediate-risk. Nevertheless, there are still questions regarding TAVI involving paravalvular leak, stroke, pacemaker requirements, and durability, which remain to be more definitively answered before TAVI can routinely be performed in lower risk and younger population. Improvements in patient selection, multimodal imaging, and third generation devices have significantly decreased the incidence of TAVI complications. A role for post-procedure antithrombotic or anticoagulant management remains unanswered. Waiting for current studies to provide us with clear answers to these questions, it is the Heart Team's task to determine the optimal treatment for each patient based on risk scores, frailty metrics, comorbidities, patient's preference, and potential for improvement in quality of life.

Abstract
The management of complex cardiovascular disease has changed considerably with the development of new care strategies. In cardiology, the «Heart Team» or literally «Equipe du cœur» occupies a prominent place in the latest European and American recommendations, particularly in the management of complex coronary or valvular diseases and in heart failure patients. The concept of «Heart Team» is based on the need for a multidisciplinary holistic approach based on evidence (respect of the recommendations of the scientific societies), the patient as a whole (comorbidities, preferences), risks and long-term benefits of the treatment selected and performed, as well as on the level of local expertise. It aims to determine the best management strategy for the patient, and perhaps to guarantee a better result (prognosis).

Abstract
Lower extremity artery disease (LEAD) is frequent and too often neglected. The ongoing evolution of endovascular techniques has revolutionised its management. Vascular surgery is still recommended in specific clinical situations. It can be performed alone or combined with angioplasty-stenting in a hybrid procedure. Various parameters related to the patient, his pathology and to the medical team must be considered especially as randomized trials comparing devices and techniques are lacking. Technical progress should not mask the high cardiovascular morbi-mortality risk of these patients. Therefore LEAD must be detected as soon as possible and optimally managed by a multidisciplinary team. According to clinical stage and comorbidities, the team can include a general practitioner, an angiologist, a cardiologist, a nephrologist, a diabetologist, an oncologist, a radiologist, a vascular surgeon, a dermatologist, etc. Medical treatment of atherosclerosis and prevention are mandatory, as well as walking exercise. Due to its high cardiovascular and amputation risk, chronic limb-threatening ischemia must be quickly and optimally managed by a multidisciplinary team.

Abstract
Coronarography consists in selective angiography of the coronary arteries obtained invasively. It represents the gold standard for the anatomical exploration of the coronary arteries and establishes the first step for the indication of possible percutaneous or surgical revascularisation. According to substantial progress, it represents an essential diagnostic tool frequently used with, despite its invasive characteristic, a very low complication's rate. The present article describes the patient's preparation for this procedure, technical modalities, major indications, contraindications and possible complications.

Abstract
Sympathetic hyperactivity is involved in the early stages of hypertension (HTN) and the mechanism persists during the course of HTN until organ damage and significant increase in cardiovascular risk. Radiofrequency renal denervation (RDN) using a percutaneous catheter inserted into the renal artery helps to destroy adventitial sympathetic nerve fibers, interrupting the connections between the renal sympathetic system and the central nervous system. After the first very encouraging clinical results in a small number of patients, the SIMPLICITY HTN-3 study halted the expansion of the technique because of negative results. From there, the technique has been redesigned conceptually as well as technically with the development of a new quadripolar spiral catheter. The first results of the SPYRAL program show this time a proven efficacy in hypertension and a larger study is underway. The results of this trial will help us to decide definitively on the future of this technique. Other pathologies such as heart failure, atrial fibrillation, obstructive sleep apnea and insulin resistance could also be improved by the RDN and studies to demonstrate this are ongoing.

Abstract
Gallbladder mucocele (GBM) is a common extra-hepatic biliary syndrome in dogs with death rates ranging from 7 to 45%. Therefore, the aim of this study was to identify the association of survival with variables that could be utilized to improve clinical decisions. A total of 1194 dogs with a gross and histopathological diagnosis of GBM were included from 41 veterinary referral hospitals in this retrospective study. Dogs with GBM that demonstrated abnormal clinical signs had significantly greater odds of death than subclinical dogs in a univariable analysis (OR, 4.2; 95% CI, 2.14-8.23; P<0.001). The multivariable model indicated that categorical variables including owner recognition of jaundice (OR, 2.12; 95% CI, 1.19-3.77; P=0.011), concurrent hyperadrenocorticism (OR 1.94; 95% CI, 1.08-3.47; P=0.026), and Pomeranian breed (OR, 2.46; 95% CI 1.10-5.50; P=0.029) were associated with increased odds of death, and vomiting was associated with decreased odds of death (OR, 0.48; 95% CI, 0.30-0.72; P=0.001). Continuous variables in the multivariable model, total serum/plasma bilirubin concentration (OR, 1.03; 95% CI, 1.01-1.04; P<0.001) and age (OR, 1.17; 95% CI, 1.08-1.26; P<0.001), were associated with increased odds of death. The clinical utility of total serum/plasma bilirubin concentration as a biomarker to predict death was poor with a sensitivity of 0.61 (95% CI, 0.54-0.69) and a specificity of 0.63 (95% CI, 0.59-0.66). This study identified several prognostic variables in dogs with GBM including total serum/plasma bilirubin concentration, age, clinical signs, concurrent hyperadrenocorticism, and the Pomeranian breed. The presence of hypothyroidism or diabetes mellitus did not impact outcome in this study.

Abstract
There is considerable debate over how different agricultural management systems such as minimum tillage and grazing affect soil organic carbon (SOC), soil nitrogen (SN) concentrations and soil erosion over the long-term. In this study SOC, SN and erosion characteristics were compared over a ten year period for two neighbouring sites with longstanding but different land management strategies; one cropped under a minimum tillage (MT) regime and one used for grazing on largely native pasture. Both sites (Hunter Valley, New South Wales, Australia) shared the same soil type (Euchrozem) and climate. SOC and SN were both found to be ~50% higher at the grazing site while erosion was found to be significantly greater (an order of magnitude) at the cropping site despite the application of MT practices. No discernible link between erosion and either SOC, SN or C:N was evident. While both sites have temporally constant SOC, SN and C:N, the MT site offers scope for increased SOC sequestration.

Response to Novel Drugs before and after Allogeneic Stem Cell Transplantation in Patients with Relapsed Multiple Myeloma. Biol Blood Marrow Transplant 2019; 25:1703-1712.

Abstract
Multiple myeloma (MM) remains as an incurable disease and, although allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative approach, most patients ultimately relapse, and their treatment remains challenging. Because allo-HSCT can modify not only the biology of the disease, but also the immune system and the microenvironment, it can potentially enhance the response to rescue therapies. Information on the efficacy and safety of novel drugs in patients relapsing after allo-HSCT is lacking, however. The objectives of this study were to evaluate the efficacy and toxicity of rescue therapies in patients with MM who relapsed after allo-HSCT, as well as to compare their efficacy before and after allo-HSCT. This retrospective multicenter study included 126 consecutive patients with MM who underwent allo-HSCT between 2000 and 2013 at 8 Spanish centers. All patients engrafted. The incidence of grade II-IV acute graft-versus-host disease (GVHD) was 47%, and nonrelapse mortality within the first 100 days post-transplantation was 13%. After a median follow-up of 92 months, overall survival (OS) was 51% at 2 years and 43% at 5 years. The median progression-free survival after allo-HSCT was 7 months, whereas the median OS after relapse was 33 months. Patients relapsing in the first 6 months after transplantation had a dismal prognosis compared with those who relapsed later (median OS, 11 months versus 120 months; P < .001). The absence of chronic GVHD was associated with reduced OS after relapse (hazard ratio, 3.44; P < .001). Most patients responded to rescue therapies, including proteasome inhibitors (PIs; 62%) and immunomodulatory drugs (IMiDs; 77%), with a good toxicity profile. An in-depth evaluation, including the type and intensity of PI- and IMiD-based combinations used before and after allo-HSCT, showed that the overall response rate and duration of response after allo-HSCT were similar to those seen in the pretransplantation period. Patients with MM who relapse after allo-HSCT should be considered candidates for therapy with new drugs, which can achieve similar response rates with similar durability as seen in the pretransplantation period. This pattern does not follow the usual course of the disease outside the transplantation setting, where response rates and time to progression decreases with each consecutive line of treatment.

Abstract
BACKGROUND In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS This was a multicenter, open-label, phase I-II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day ‒1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. RESULTS A total of 66 patients were recruited (median age 36 years; range 18-66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3-4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3-4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2×10e6/kg CD34+ cells (median 5.75; range 2.12-33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). CONCLUSION BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival.

Abstract
Progesterone (P4) is of paramount importance in the establishment and maintenance of pregnancy for mammals. Progesterone stimulates the endometrial secretion of several molecules involved in conceptus growth and development during the peri-implantation period. Indeed, several studies involving ruminants have reported that exogenous P4 supplementation is related to increased early embryo development, higher levels of interferon tau, and improved pregnancy rate. However, there is a lack of information about P4 supplementation during early pregnancy regarding swine embryonic development. Additionally, some of the few studies involving pigs have shown an impaired pregnancy rate when supplementation was performed before Day 6 of pregnancy. Thus, the objective of this study was to evaluate the effects of progesterone/progestin supplementation from Day 6 of pregnancy on total number of embryos (TE), pregnancy rate (PR), embryo development, and maternal serum 17β-oestradiol concentration (17β-E). A total of 31 crossbred, 2 to 6 parity sows were used. All sows were inseminated every 24h through the first oestrus following a 21-day lactation, and ovulation was detected by transrectal real-time ultrasound to determine Day 0 of pregnancy. On Day 6 of pregnancy, animals were randomly allocated to one of the following groups: CON (n=11), non-supplemented sows; RU (n=11), sows supplemented daily with 20mg of Altrenogest-Regumate® from Day 6 to 12 of pregnancy; and PG (n=9), sows supplemented with 2.15 mg/kg of long-acting P4 IM on Day 6 of pregnancy. Sows were treated with altrenogest p.o. as a top dressing over a small portion of feed. Blood samples were collected from 12 sows (4 per group) on Day 12 of pregnancy to measure the level of plasma 17β-E by radioimmunoassay. Sows were slaughtered on Day 28 of pregnancy. The uterus from each sow was collected and embryos were counted to determine TE. Embryos were individually separated from their placentas, weighed, and crown-to-rump length was determined. Data were analysed by the SAS program. All variables were analysed by PROC-MIXED t-test. Statistical difference was considered when P<0.05. The PR did not differ among groups (91, 90, and 88%, for CON, RU, and PG, respectively; P>0.05). No difference was observed among groups for TE and 17β-E level (P>0.05). However, embryonic weight and crown-to-rump length differed among the 3 groups (P<0.001). The RU-treated sows had heavier and bigger embryos when compared with the other groups. In contrast, PG-treated sows had the lowest averages for the same variables (weight: 1.39±0.01, 1.46±0.02, and 1.22±0.01; crown-to-rump: 21.07±0.08, 21.61±0.11, and 20.66±0.11; for CON, RU, and PG, respectively). In conclusion, altrenogest supplementation from Day 6 to 12 of pregnancy increases size and weight of porcine embryos, whereas 2.15mg kg−1 of long-acting P4 on Day 6 of pregnancy decreased these variables when compared with non-supplemented sows.

Abstract
Background:
The expressive difficulties in patients with Alzheimer’s dementia have been
extensively studied, mainly in oral language. However, the deterioration of their writing processes has
received much less attention.
Objective:
The present study aims to examine the decline of the performance of patients with Alzheimer’s
disease in both oral and written picture-naming tasks.
Method:
Sixty-four participants (half with Alzheimer’s disease and half healthy elderly) were compared
in the oral and written versions of a picture-naming task. Follow-up lasted two and a half years and patients
were evaluated every six months.
Results:
Cross-sectional data indicate that the controls performed better than the patients, and both
groups showed a different pattern of errors. In terms of longitudinal data, the results show a similar pattern
of deterioration in both tasks. In terms of errors, lexical-semantics were the most numerous at the
beginning and their number remained constant throughout all evaluations. In the case of non-responses,
there was a significant increase in the last session, both in oral and written naming.
Conclusion:
These results replicate those found in previous studies and highlight the utility of the naming
task to detect minimal changes in the evolution of patients with Alzheimer’s disease.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of
unresolved organised pulmonary emboli/thrombi obstructing the major pulmonary
arteries. The aim of this study was to estimate the incidence and risk factors
of CTEPH in a cohort with first venous thromboembolism (VTE). This was a
population-based cohort study of patients with first VTE and no active cancer in
England between 2001 and 2012. CTEPH was assessed using a rigorous
case-ascertainment algorithm. Risk factors for CTEPH were studied using a nested
case-control approach by matching CTEPH cases to VTE patients without CTEPH.
Adjusted odds ratios (OR) of comorbidities were estimated from conditional
logistic regression. During 81,413 person-years of follow-up among 23,329
patients with first VTE (mean follow-up 3.5 years; maximum 11.0 years) 283
patients were diagnosed with CTEPH (incidence rate 3.5 per 1000 person-years);
cumulative incidence was 1.3% and 3.3% at 2 and 10 years after pulmonary
embolism, and 0.3% and 1.3% following deep vein thrombosis (DVT), respectively.
Risk factors for CTEPH included age over 70, OR 2.04 (95% CI 1.23 to 3.38),
female gender, 1.44 (1.06 to 1.94), pulmonary embolism at first VTE, 3.11 (2.23
to 4.35), subsequent pulmonary embolism and DVT, 3.17 (2.02 to 4.96) and 2.46
(1.34 to 4.51) respectively, chronic obstructive pulmonary disease 3.17 (2.13 to
4.73), heart failure 2.52 (1.76 to 3.63) and atrial fibrillation, 2.42 (1.71 to
3.42). CTEPH develops most commonly after pulmonary embolism and less frequently
after DVT. Awareness of risk factors may increase referrals to specialised
centres for confirmation of CTEPH and initiation of specific treatment.

Abstract
An ongoing clinical trial is testing the efficacy of web telematic support in a structured program for obesity treatment and diabetes prevention. Participants were recruited from two tertiary-care hospitals and randomized to receive either a telematic intervention (TI) supported by PREDIRCAM2 web platform or a non-telematic intervention (NTI). All receive 1-year follow-up. Both interventions consist of tailored dietary and exercise prescriptions, based on a Mediterranean dietary pattern and general WHO exercise recommendations for adults. At 6 months, both groups have received 7 contacts, 3 exclusively telematic for the TI group. This is a preliminary result intention-to-treat analysis. One hundred eighty-three participants were recruited, with a mean body mass index of 34.75 ± 2.75 kg/m2. General dropout rate at 6 months was 26.8%. Weight changes were statistically significant at months 3 and 6 compared to baseline, -2.915 ± 0.24 kg, -3.29 ± 0.36 kg, respectively (P < 0.001), but not statistically significant between the 3- and 6-month time points -0.37 ± 0.21 kg (P = 0.24). Mean group differences showed that the TI group lost 1.61 ± 1.88 kg more than the NTI group (P = 0.39). Waist, waist/hip ratio, resting heart rate, blood pressure, HbA1c, and low-density lipoprotein cholesterol also showed statistically significant changes at 6 months, with no significant differences between groups. Weight loss in the TI group shows similar results as the usual care NTI group for weight loss and control of obesity comorbidities. At completion of the clinical trial, these results will be reevaluated to assess the potential role of web support in weight-loss maintenance and its cost-effectiveness.

Abstract
BACKGROUND Alterations of site-specific gene expression profiles in disease-relevant networks within the different layers of the intestinal wall may contribute to the onset and clinical course of gastrointestinal disorders. To date, no systematic analysis has assessed and compared sub-regional gene expression patterns in all distinct layers of the gut using fresh frozen human samples. Our aim was to establish an optimized protocol for site-specific RNA isolation in order to achieve maximum RNA quality and amount for subsequent gene expression analysis combining laser-capture microdissection (LCM) with a probe-based technology, the NanoString nCounter Analysis system. METHODS Four full-thickness colon samples from patients who underwent surgery due to pathological conditions were processed and separated into epithelium, lamina propria, myenteric plexus, submucosa, and tunica muscularis by LCM. Site-specific marker expression by nCounter technology was performed on total RNA from each sub-region, respectively. KEY RESULTS Collecting ~10 mm² (~100 000-250 000 cells) of tissue from the epithelial layer, lamina propria, and myenteric plexus provided sufficient amounts of RNA of appropriate quality for subsequent analyses. In contrast, ~40 mm² (~250 000-650 000 cells) of tissue were dissected from the less cell-rich submucosal and tunica muscularis layer. nCounter analysis revealed a site-specific expression pattern of marker genes in the different layers of the colonic wall which were highly correlating (r > .9). CONCLUSIONS AND INFERENCES LCM in combination with nCounter expression analysis enables site-specific, sensitive, reliable detection, and quantification of mRNA from histologically heterogeneous tissues.

Brentuximab vedotin prior to allogeneic stem cell transplantation in Hodgkin lymphoma: a report from the EBMT Lymphoma Working Party. Br J Haematol 2018; 181:86-96.

Abstract
Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate. Preliminary data suggest that BV might improve outcomes after allogeneic stem cell transplantation (SCT) for Hodgkin lymphoma (HL) when used as pre-transplant salvage therapy. Between 2010 and 2014, 428 adult patients underwent an allogeneic SCT for classical HL at participating centres of the European Society for Blood and Marrow Transplantation. We compared the outcomes of 210 patients who received BV prior to allogeneic SCT with that of 218 patients who did not receive BV. The median follow-up for survivors was 41 months. Patients in the BV group were more heavily pre-treated (median pre-allograft treatment lines: 4 vs. 3). The two groups were comparable in terms of disease status, performance status, comorbidities, prior autologous SCT, type of donor, conditioning and in vivo T cell depletion. In multivariate analysis, pre-allograft BV had no impact on acute graft-versus-host disease (GVHD), non-relapse mortality, cumulative incidence of relapse, progression-free survival or overall survival (OS), but significantly reduced the risk of chronic GVHD (hazard ratio = 0·64; 95% confidence interval = 0·45-0·92; P < 0·02). Older age, poor performance status, use of pre-transplant radiotherapy and active disease at SCT adversely affected OS. Patients allografted for HL after prior exposure to BV do not have a superior outcome after allogeneic SCT except for a lower risk of chronic GVHD. However, BV may improve the outlook of allogeneic SCT by helping otherwise refractory patients to achieve a more favourable disease status, facilitating allotransplant success.

Abstract
Purpose To compare the safety and efficacy of a new enhanced viscosity ophthalmic formulation of tobramycin, given twice daily (BID), with the existing four times daily (QID) treatment regimen in patients with acute bacterial conjunctivitis. Methods This was a 12-day, multicenter, observer-masked, randomized, parallel group study. Patients received one drop of tobramycin 0.3% (3 mg/mL) enhanced viscosity ophthalmic solution BID or tobramycin 0.3% (3 mg/mL) ophthalmic solution QID in the affected eyes for 7 days. The primary efficacy variable was the percentage of patients with sustained cure/presumed bacterial eradication based on clinical judgment at the test-of-cure visit (Day 12). Pretherapy bacterial isolates were obtained and tested for susceptibility to tobramycin by determination of minimum inhibitory concentrations (MIC). Results A total of 276 patients were enrolled in the study and 203 of these were culture positive and attended all follow-up examinations. In this group, 98% of those treated with tobramycin enhanced viscosity ophthalmic solution and 99% of those treated with tobramycin 0.3% ophthalmic solution were categorized as having sustained cure/presumed eradication at the test-of-cure visit (p=0.6037). Reported adverse events were not serious, mild to moderate in severity, and generally did not prevent continuation in the study. Several pretreatment pathogens demonstrated tobramycin resistance (MIC > 4 mg/mL). However, therapy with both treatments was effective in the majority of the cases. Conclusions Tobramycin enhanced viscosity ophthalmic solution is well tolerated and has equivalent efficacy to the established treatment regimen with a simplified posology. The formulation provides an alternative therapy for acute bacterial conjunctivitis that should improve patient compliance and satisfaction.

Abstract
Vaginoplasty by penile and scrotal skin inversion is a well-established technique for male-to-female gender confirmation surgery. In this setting, chronic inflammation and lacerations associated with history of human papillomavirus (HPV) infection may induce a high risk of malignant degeneration in the long term. A 78-year-old transgender woman was admitted with genital discomfort and neovaginal discharge. The patient’s history revealed male-to-female gender confirmation surgery with construction of a neovagina by penile and scrotal skin inversion at 33 years of age. Physical examination of the genitalia revealed presence of fecal material, suggestive of recto-neovaginal fistula. A biopsy specimen was positive for well-differentiated HPV-related squamous cell carcinoma. Magnetic resonance imaging (MRI) showed a bulky mass in the posterior wall of the neovagina that infiltrated the urethra, prostatic gland and the anterior rectal wall. Following a multidisciplinary evaluation, we performed a definitive sigmoid colostomy and administered chemotherapy. Long-term follow-up seems advisable in patients after vaginoplasty due to the possibility of delayed development of cancer. Following biopsy, we consider MRI as the modality of choice to identify possible infiltration of the adjacent structures. As data regarding these lesions are scarce and management is complex, a multidisciplinary approach is recommended.

Abstract
BACKGROUND The incidence of perineal hernia after abdominoperineal excision and extralevator abdominoperineal excision ranges from 1 to 26%. In this systematic review, we compared surgical options and postoperative outcomes of perineal hernia repair in this setting from 2012 to 2016 with findings in a review of publications 1944-2011. METHODS We searched the PubMed database using the keywords "hernia" AND "perineum" identified 392 papers published from 1946 to 2016. Two hundred and ninety-six papers published before 2012 were excluded and 96 were found to be potentially relevant. RESULTS Twenty-one studies with a total of 108 patients were included in the final analysis. Perineal hernia repair was performed using the perineal approach in 75 patients (69.44%), the laparoscopic approach in 25 patients (23.14%), the open abdominal approach in three patients (2.77%) and the laparoscopic perineal approach in three patients (2.77%) and the open abdominoperineal approach in two patients (1.8%). Non-absorbable mesh was used in 41 (37.96%) of cases, composite mesh in 20 (18.51%) and biological mesh in 19 (17.59%). Flap reconstruction was used in 25 patients (23.14%). First and second recurrences were observed in 26 (24.07%) and 7 (26.92%) cases, respectively. CONCLUSIONS Comparison of perineal hernia repair from 1944 to 2011 and from 2012 to 2016 showed that perineal and laparoscopic approaches are currently the most commonly used techniques. Primary defect closure was abandoned in favor of synthetic or composite mesh placement. Use of flap reconstruction spread rapidly and the recurrence rate was low. Randomized control trials and a larger sample size are needed to confirm these data and to develop a gold standard treatment for secondary hernia repair after abdominoperineal excision or extralevator abdominoperineal excision.

Diagnostic potential of NETosis-derived products for disease activity, atherosclerosis and therapeutic effectiveness in Rheumatoid Arthritis patients. J Autoimmun 2017; 82:31-40.

Abstract
OBJECTIVES 1) To assess the association of NETosis and NETosis-derived products with the activity of the disease and the development of cardiovascular disease in RA; 2) To evaluate the involvement of NETosis on the effects of biologic therapies such as anti-TNF alpha (Infliximab) and anti-IL6R drugs (Tocilizumab). METHODS One hundred and six RA patients and 40 healthy donors were evaluated for the occurrence of NETosis. Carotid-intimae media thickness was analyzed as early atherosclerosis marker. Inflammatory and oxidative stress mediators were quantified in plasma and neutrophils. Two additional cohorts of 75 RA patients, treated either with Infliximab (n = 55) or Tocilizumab (n = 20) for six months, were evaluated. RESULTS NETosis was found increased in RA patients, beside myeloperoxidase and neutrophil elastase protein levels. Cell-free nucleosomes plasma levels were elevated, and strongly correlated with the activity of the disease and the positivity for autoantibodies, alongside inflammatory and oxidative profiles in plasma and neutrophils. Moreover, ROC analyses showed that cell-free nucleosomes levels could identify RA patients showing early atherosclerosis with high specificity. RA patients treated either with IFX or TCZ for six months exhibited decreased generation of NETs. Concomitantly, clinical parameters and serum markers of inflammation were found reduced. Mechanistic in vitro analyses showed that inhibition of NETs extrusion by either DNase, IFX or TCZ, further abridged the endothelial dysfunction and the activation of immune cells, thus influencing the global activity of the vascular system. CONCLUSIONS NETosis-derived products may have diagnostic potential for disease activity and atherosclerosis, as well as for the assessment of therapeutic effectiveness in RA.

Abstract
Several studies in multiple sclerosis (MS) suggest a trend of increasing disease frequency in women during the last decades. A direct comparison of gender ratio trends among MS populations from Argentina remains to be carried out. The objective of the study was to compare gender ratio trends, over a 50-year span in MS populations from Argentina. METHODS multicenter study that included patients from 14 MS Centers of Argentina. Patients with definite MS with birth years ranging from 1940 to 1989 were included. Gender ratios were calculated by five decades based on year of birth and were adjusted for the F/M born-alive ratio derived from the Argentinean national registry of births. The F/M ratios were calculated using a multivariate logistic regression per five decades by the year of birth approach. Analyses were performed using Stata 10.1. RESULTS 1069 patients were included. Gender ratios showed a significant increase from the first to the last decade in the whole MS sample (from 1.8 to 2.7; p value for trend=0.023). The Gender ratio did not show differences considering MS subtype. CONCLUSION our study showed a modest increase of the F/M ratio (from 1.8 to 2.7) over time among patients affected by MS in Argentina.

Fludarabine with pharmacokinetically guided IV busulfan is superior to fixed-dose delivery in pretransplant conditioning of AML/MDS patients. Bone Marrow Transplant 2016; 52:580-587.

Abstract
We hypothesized that IV Busulfan (Bu) dosing could be safely intensified through pharmacokinetic (PK-) dose guidance to minimize the inter-patient variability in systemic exposure (SE) associated with body-sized dosing, and this should improve outcome of AML/MDS patients undergoing allogeneic stem cell transplantation (allo-HSCT). To test this hypothesis, we treated 218 patients (median age 50.7 years, male/female 50/50%) with fludarabine (Flu) 40 mg/m2 once daily ×4, each dose followed by IV Bu, randomized to 130 mg/m2 (N=107) or PK-guided to average daily SE, AUC of 6,000 µM-min (N=111), stratified for remission-status, and allo-grafting from HLA-matched donors. Toxicity and graft vs. host disease (GvHD) rates in the groups were similar; the risk of relapse or treatment-related mortality remained higher in the fixed-dose group throughout the 80-month observation period. Further, PK-guidance yielded safer disease-control, leading to improved overall and progression-free survival, most prominently in MDS-patients and in AML-patients not in remission at allo-HSCT. We conclude that AML/MDS patients receiving pretransplant conditioning treatment with our 4-day regimen may benefit significantly from PK-guided Bu-dosing. This could be considered an alternative to fixed dose delivery since it provides the benefit of precise dose delivery to a predetermined SE without increasing risk(s) of serious toxicity and/or GvHD.

Abstract
The role that changes in DNA methylation and histone modifications have in human malignancies is poorly understood. p300 and CREB-binding protein (CBP), two distinct but highly homologous lysine acetyltransferases, are mutated in several cancers, suggesting their role as tumor suppressors. In the current study, we found that deletion of p300, but not CBP, markedly accelerated the leukemogenesis ofNup98-HoxD13 (NHD13) transgenic mice, an animal model that phenotypically copies human myelodysplastic syndrome (MDS). p300 deletion restored the ability of NHD13 expressing hematopoietic stem and progenitor cells (HSPCs) to self-renew in vitro, and to expand in vivo, with an increase in stem cell symmetric self-renewal divisions and a decrease in apoptosis. Furthermore, loss of p300, but not CBP, promoted cytokine signaling, including enhanced activation of the MAPK and JAK/STAT pathways in the HSPC compartment. Altogether, our data indicate that p300 has a pivotal role in blocking the transformation of MDS to acute myeloid leukemia, a role distinct from that of CBP.

FCERI and Histamine Metabolism Gene Variability in Selective Responders to NSAIDS. Front Pharmacol 2016; 7:353.

Abstract
The high-affinity IgE receptor (Fcε RI) is a heterotetramer of three subunits: Fcε RIα, Fcε RIβ, and Fcε RIγ (αβγ2) encoded by three genes designated as FCER1A, FCER1B (MS4A2), and FCER1G, respectively. Recent evidence points to FCERI gene variability as a relevant factor in the risk of developing allergic diseases. Because Fcε RI plays a key role in the events downstream of the triggering factors in immunological response, we hypothesized that FCERI gene variants might be related with the risk of, or with the clinical response to, selective (IgE mediated) non-steroidal anti-inflammatory (NSAID) hypersensitivity. From a cohort of 314 patients suffering from selective hypersensitivity to metamizole, ibuprofen, diclofenac, paracetamol, acetylsalicylic acid (ASA), propifenazone, naproxen, ketoprofen, dexketoprofen, etofenamate, aceclofenac, etoricoxib, dexibuprofen, indomethacin, oxyphenylbutazone, or piroxicam, and 585 unrelated healthy controls that tolerated these NSAIDs, we analyzed the putative effects of the FCERI SNPs FCER1A rs2494262, rs2427837, and rs2251746; FCER1B rs1441586, rs569108, and rs512555; FCER1G rs11587213, rs2070901, and rs11421. Furthermore, in order to identify additional genetic markers which might be associated with the risk of developing selective NSAID hypersensitivity, or which may modify the putative association of FCERI gene variations with risk, we analyzed polymorphisms known to affect histamine synthesis or metabolism, such as rs17740607, rs2073440, rs1801105, rs2052129, rs10156191, rs1049742, and rs1049793 in the HDC, HNMT, and DAO genes. No major genetic associations with risk or with clinical presentation, and no gene-gene interactions, or gene-phenotype interactions (including age, gender, IgE concentration, antecedents of atopy, culprit drug, or clinical presentation) were identified in patients. However, logistic regression analyses indicated that the presence of antecedents of atopy and the DAO SNP rs2052129 (GG) were strongly related (P < 0.001 and P = 0.005, respectively) with selective hypersensitivity to ibuprofen. With regard to patients with selective hypersensitivity to ASA, men were more prone to develop such a reaction than women (P = 0.011), and the detrimental DAO SNP rs10156191 in homozygosity increased the risk of developing such hypersensitivity (P = 0.039).

Risk of recurrent venous thromboembolism after discontinuation of vitamin K antagonist treatment: a nested case-control study. J Thromb Haemost 2016; 14:1374-83.

Abstract
UNLABELLED Essentials Vitamin K antagonists (VKA) in venous thromboembolism (VTE) lower the risk of recurrences. 41 841 VKA-treated VTE patients had 1242 recurrent VTEs on therapy or early after cessation. An increased risk of recurrence was found in the first 120 days after VKA cessation. Patient education for the early detection of recurrent VTE after VKA cessation is recommended. SUMMARY Background The standard treatment for venous thromboembolism (VTE) and the prevention of recurrent VTE (rVTE) consists of anticoagulant therapy. The optimal duration of anticoagulation depends on the presence of risk factors for rVTE. Objectives To estimate the risk of rVTE in association with time since discontinuation of vitamin K antagonist (VKA) treatment. Methods From the UK Clinical Practice Research Datalink with linked information on hospitalization and cause of death, a cohort of patients with a first VTE receiving initial VKA treatment between 2001 and 2013 was formed. With a nested case-control approach, patients with incident rVTE (cases) were matched to patients with VTE but without rVTE (controls). Adjusted rate ratios (RRs) of rVTE associated with time since VKA discontinuation relative to current VKA use were estimated from conditional logistic regression. Results The VTE cohort comprised 41 841 patients with 1242 rVTEs and 6205 matched controls. The RR of rVTE was increased within 60 days following VKA discontinuation (RR 2.23, 95% confidence interval [CI] 1.71-2.91) and within 61-120 days following VKA discontinuation (RR 1.49, 95% CI 1.08-2.05) relative to current VKA use. The increased RR corresponded to excess incidence rates of 6.72 (95% CI 3.90-10.06) rVTE cases per 100 person-years within 60 days, and of 2.68 (95% CI 0.42-5.58) rVTE cases per 100 person-years within 61-120 days after VKA discontinuation. Conclusions VKA discontinuation results in a transient increased risk of rVTE, which peaks within 60 days and lasts for up to 120 days after VKA discontinuation. Specific patient education for increased vigilance for signs and symptoms of recurrences is recommended in this period.

Plasma Matrix Metalloproteinases in Patients With Stroke During Intensive Rehabilitation Therapy. Arch Phys Med Rehabil 2016; 97:1832-1840. [PMID: 27373742 DOI: 10.1016/j.apmr.2016.06.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2015] [Revised: 05/26/2016] [Accepted: 06/08/2016] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To study plasma levels of matrix metalloproteinases (MMPs) as potential markers of recovery during intensive rehabilitation therapy (IRT) after stroke. DESIGN Prospective and descriptive 3-month follow-up study. SETTING Rehabilitation unit and research center. PARTICIPANTS Patients with first-ever ischemic stroke (n=15) enrolled to IRT (≥3h/d and 5d/wk) and healthy volunteers (n=15) (N=30). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The primary outcome was to measure plasma MMP3, MMP12, and MMP13 levels and evaluate potential associations with motor/functional scales using a battery of tests (National Institutes of Health Stroke Scale, modified Rankin scale, Barthel Index, Fugl-Meyer Assessment, Functional Ambulation Categories, Medical Research Council scale, Chedoke Arm and Hand Activity Inventory, and the 10-m walk test) before IRT and at 1- and 3-month follow-ups. The secondary outcome was to evaluate the use of these MMPs as biomarkers as predictors of patient's outcome. RESULTS MMP levels remained stable during the study period and were similar to those in the healthy volunteer group. However, baseline MMP12 and MMP13 levels were strongly associated with stroke severity and were found to be elevated in those patients with the poorest outcomes. Interestingly, plasma MMP3 was independent of baseline stroke characteristics but was found to be increased in patients with better motor/functional recovery and in patients with larger improvements during rehabilitation. CONCLUSIONS MMPs might act as biologic markers of recovery during rehabilitation therapy related to their roles in both injury and tissue remodeling. Future confirmatory investigations in multicenter studies are warranted by our data.
