Approximately 9 million ha of wheat (Triticum aestivum and T. durum) is sown in the Southern Cone of America (Argentina, Brazil, Chile, Paraguay, and Uruguay). Two rust epidemiological zones separated by the Andean mountain range have been described in the region. Presently, leaf rust (caused by Puccinia triticina) is the most important rust disease of wheat. The utilisation of susceptible or moderately susceptible cultivars in a high proportion of the wheat area allows the pathogen to oversummer across large areas, resulting in early onset of the epidemics. Severe epidemics cause important economic losses if chemical control is not used. The pathogen population is extremely dynamic, leading to transitory resistance in commercial cultivars. Lr34 is commonly present in the regional germplasm, but there is limited knowledge about the presence of other genes conferring resistance in cultivars. Genes Lr28, Lr36, Lr38, Lr41, and Lr43 provide effective resistance in the region. The best strategy for the stabilisation of the pathogen population and resistance is considered to be the use of adult plant resistance conferred by minor additive genes including Lr34 and Lr46. Sources of this type of resistance from CIMMYT and the region have been made available to breeding programs in the Southern Cone. Stripe rust (P. striiformis f. sp. tritici) is endemic in Chile where chemical control is required to prevent severe losses in stripe rust susceptible cultivars. Although new virulent races emerge frequently, resistance genes Yr5, Yr8, Yr10, Yr15, and YrSp are currently effective in Chile. Some important stripe rust epidemics have occurred in Argentina, Brazil, and Uruguay. Avoiding the use of highly susceptible cultivars appears to be an effective strategy to prevent stripe rust epidemic development in this area. There have been no serious stem rust (P. graminis f. sp. tritici) epidemics for over 2 decades; the disease was controlled by resistant cultivars. The most important genes conferring resistance in Southern Cone germplasm at the present time are probably Sr24 and Sr31. Other effective genes are Sr22, Sr25, Sr26, Sr32, Sr33, Sr35, Sr39, and Sr40. Several stem rust susceptible wheat cultivars have recently been released. The increased cultivation of susceptible cultivars may lead to higher stem rust incidence, increasing the probability of appearance of new virulent races. Since the 1BL.1RS translocation possessing Sr31 is present in a high proportion of the regional germplasm, the possible introduction of stem rust with Sr31 virulence from Africa is of great concern.

The aim of this study was to determine the minimum prevalence of coeliac disease in a group of 459 diabetic children and adolescents. Six patients were already known to have coeliac disease. A total of 436 patients with type 1 diabetes mellitus aged 2-21 years and with age at onset at 2 months to 17 years at three paediatric departments agreed to participate in the study. All patients were tested for gliadin IgA antibodies with a commercial kit (Pharmacia Gluten IgA EIA). Later, serum was tested for reticulin IgA/IgG antibodies. Nineteen patients had elevated gliadin IgA levels (> 25 AU). Eighteen underwent jejunal biopsy. Ten had total or subtotal villous atrophy. These 10 patients were reticulin IgA-positive. Of 417 gliadin IgA-negative patients, 408 were reticulin IgA/IgG-negative. Of 6 reticulin IgA-positive patients, 3 had total or subtotal villous atrophy. All 3 had become gliadin IgA-positive at the time of biopsy. Among 3 reticulin IgG-positive patients with IgA deficiency, 2 had total villous atrophy: 1 was not willing to be biopsied. Patients with total or subtotal villous atrophy were judged as having coeliac disease and were recommended a gluten-free diet. Within 2 months, gliadin IgA levels were normal in patients adhering to the diet. Five patients have gone through a second jejunal biopsy to date with normal histology in all 5. The 15 newly diagnosed patients with coeliac disease plus 6 already known patients with coeliac disease and type 1 diabetes mellitus gave a minimum prevalence of coeliac disease in diabetic children and adolescents of 21/459 = 4.6%.

The use of herbal remedies by African farmers in the treatment of livestock diseases was investigated using a range of methods, including group interviews, structured interviews, semi-structured interviews and participant observation. The study was concerned mainly with the 'why' and 'how' of herbal remedy use among African livestock holders farming on communally-owned land in central Eastern Cape Province. We found that the use of herbal remedies was still widespread because these remedies were cheap, locally available and convenient to administer. Farmers also used herbal remedies because they did not have knowledge of conventional remedies or found these too expensive and therefore used herbal remedies as a last resort. Most of the farmers interviewed (73%) had used some form of herbal remedy. A small number of farmers did not use herbal remedies at all. They rejected them because they had bad experiences in the past or because they considered the practice outdated and socially inferior. Often farmers used herbal remedies in combination with conventional ones, but a substantial number relied on herbal remedies only. Farmers obtained herbal remedies principally by preparing their own or by purchasing from herbalists. Different plant parts were used to prepare herbal remedies in the form of infusions, decoctions, powders, pastes, and juices from fresh plant material. Preparations were made from a single plant or from a range of plants. Application of a remedy was by different routes and methods, depending on the perceived cause of the disease condition. Topical applications were used for skin conditions, powders were rubbed into incisions, drenches were common in the treatment of systemic conditions, and drops to treat ears and eyes. We identified several aspects of herbal remedy utilisation that could be subject to improvement, which included the absence of standard dose regimes, the potential toxicity of certain compounds present in plants used, over-exploitation of the plant resource and a lack of interest by the youth to learn the art.

Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat ( Triticum aestivum L.), in Argentina. Host resistance is the most economical, effective and ecologically sustainable method of controlling the disease. Gene postulation helps to determine leaf rust resistance genes ( Lr genes) that may be present in a large group of wheat germplasm. Additionally presence of Lr genes can be determined using associated molecular markers. The objective of this study was to identify Lr genes that condition leaf rust resistance in 66 wheat cultivars from Argentina. Twenty four differential lines with individual known leaf rust resistance genes, were tested with 17 different pathotypes of leaf rust collected from Argentina. Leaf rust infection types produced on seedling plants of the 66 local cultivars were compared with the infection types produced by the same pathotypes on Lr differentials to postulate which seedling leaf rust genes were present. Presence of Lr9, Lr10, Lr19, Lr20, Lr21, Lr24, Lr25, Lr26, Lr29, Lr34, Lr35, Lr37, Lr47 and Lr51 was also determined using molecular markers. Eleven different Lr genes were postulated in the material: Lr1, Lr3a, Lr3ka, Lr9, Lr10, Lr16, Lr17, Lr19, Lr24, Lr26, Lr41. Presence of Lr21, Lr25, Lr29, and Lr47 could not be determined with the seventeen pathotypes used in the study because all were avirulent to these genes. Eleven cultivars (16.7%) were resistant to all pathotypes used in the study and the remaining 55 (83.3%) showed virulent reaction against one or more local pathotypes. Cultivars with seedling resistance gene combinations including Lr16 or single genes Lr47 (detected with molecular marker), Lr19 and Lr41, showed high levels of resistance against all pathotypes or most of them. On the opposite side, cultivars with seedling resistance genes Lr1, Lr3a, Lr3a+Lr24, Lr10, Lr3a+Lr10, Lr3a+Lr10+Lr24 showed the highest number of virulent reactions against local pathotypes. Occurrence of adult plant resistance genes Lr34, Lr35 and Lr37 in local germplasm was evaluated using specific molecular markers confirming presence of Lr34 and Lr37. Our data suggest that combinations including seedling resistance genes like Lr16, Lr47, Lr19, Lr41, Lr21, Lr25 and Lr29, with adult plant resistance genes like Lr34, SV2, Lr46 will probably provide durable and effective resistance to leaf rust in the region.

We put forward a completely redesigned approach to soft set based decision making problems under incomplete information. An algorithmic solution is proposed and compared with previous approaches in the literature. The computational performance of our algorithm is critically analyzed by an experimental study.

OBJECTIVE: The aim of this real-world study was to evaluate the effect of agomelatine on anhedonia as primary endpoint in outpatients under treatment of major depressive episodes. METHODS: The study was an open-label, multicenter, 8-week phase IV trial. Two hundred fifty-seven (257) patients were recruited, and 143 patients were included in the analysis. Agomelatine was administered orally as a 25-mg tablet. The dose could be increased to 50 mg after 2 weeks of treatment. RESULTS: An improvement in the severity of anhedonia (Snaith-Hamilton Pleasure Scale total score) was observed from 8.5 points at baseline to 4.1 at week 8, statistically significant (p < 0.05) from the first week. Significant decreases in scores on the severity of depression (Quick Inventory of Depressive Symptomatology 16-item Self-Report [QIDS-SR-16]), anxiety (Generalized Anxiety Disorder 7-item scale), and in overall clinical status (CGI) were also found over 8 weeks, independently from the presence of a first or recurrence episode. Response (QIDS-SR-16 score ≥ 50% of baseline) at week 8 was observed in 65.7% of the patients, while 49.6% of the patients achieved remission (QIDS-SR-16 score ≤ 5). CONCLUSION: Agomelatine was shown to be effective on anhedonia, depression, and anxiety in subjects with major depression. The pragmatic design of the study reflects real-world clinical practice providing interesting insights into routine care management.

Abstract Field experiments were carried out at the INTA Bordenave Agriculture Experiment Station to determine the effect of Azospirillum brasilense and Bacillus polymyxa on the yield of wheat. Seeds were inoculated with different strains of A. brasilense and a strain of B. polymyxa. Sowing was performed with 100 kg seed ha‐1 at the beginning of winter for the period 1987–1991. Azospirillum brasilense strain Az 39 increased yields of the Cochicó INTA wheat cultivar by 13.4% in 1988–1989; 24.3% in 1990–1991, and 15.5% in 1991–1992. Yields of cultivar Buck Poncho increased by 21.6%, and of Prointa Pigüé by 20.8% and 33.3% during the latter two periods. In one out of two cropping cycles, A. brasilense strain Cd increased yield of the Cochicó INTA cultivar by 25.7%. Other strains did not affect yields significantly. Strain Az 39 increased wheat yields in an unfertilized soil but not if the soil was amended with 19 kg N ha‐1 as urea. Inoculation of Cochicó INTA seeds with B. polymyxa Bp 4317 increased yield by 13.6% and 19.5% in two different years. When the bacterium was co‐inoculated with A. brasilense Cd, no synergistic effect on yield was observed. However, it increased yield of cultivar Prointa Pigüé by 20.1%. Grain protein content was not influenced by inoculation. The results suggest that wheat growing in semiarid regions of Argentina (about 2 million ha) could benefit from seed inoculation if bacterial strains and wheat cultivars are carefully selected and soil conditions are appropriate.

We studied effects of changes in the extracellular potassium concentration (|K* ]") on the mechanical responsiveness of canine coronary artery preparations. Four different contractile behaviors were delineated between | K *),, = 0 and 40 HIM: (1) at [K + ] o < 1 mu, a contracture developed which was augmented by /3-adrenergic stimulation and inhibited by propranolol, 1 x 10~7M; (2) at |K*| (I between 1 and 2.5 mti, arterial tone was minimum and propranolol acted as a potent constrictor. Within this range of [K + ],,, arteries exhibited calciuminduced relaxations and verapamil-induced contractions; (3) at |K* |,, between 5 and 15 mM there was a steep rise in force which was increased by isoproterenol (/3-adrenergic contraction), almost completely blocked by L-propranolol, but not attenuated by a-adrenergic blockade with phentolamine; (4) at |K' ] > 30 mM, effects of /3-adrenergic stimulation and blockade became very small. Steady increases in force elicited by isoproterenol and by sudden increases in [K + ] o were preceded by transient relaxations. Effects of exogenous and endogenous (tyramine, nerve stimulation) norepinephrine paralleled those of isoproterenol and were blocked by propranolol but not attenuated by phentolamine. In contrast, modulation of the effects of phenylephrine by potassium consisted of monotonicaUy increasing constrictor responses over the whole range of |K'| 0 tested. Arteries labeled with ( 3 H)-norepinephrine showed substantial changes in ( 3 H)-efTlux with relatively small changes in [K + ] o . Maximum releases were observed with |K* I,, ranging between 10 and 25 mM. The smallest releases were observed at the highest (K + | o (40 mM). Thus, changes in [K + ] o influence arterial tone by modulating or-and /3-adrenergic effects and by regulating the release of neurotransmitter from the coronary nerves.

ABSTRACT The chemical composition of the essential oils obtained by hydrodistillation of Spanish cultivated and wild growing plants from Myrtus communis L. was examined by GC/MS. Over one hundred compounds were detected in the oils, from which about fifty could be identified and quantified. The main components were found to be α-pinene (8.05–8.18%), 1,8-cineole (15.14–29.89%), linalool (0.5–8.3%), and myrtenyl acetate (32.90–35.90%). A myrtle oil of Moroccan and one of Albanian origin were also examined and their composition was compared against the lab-distilled oils from Spanish plant material. The major components of these oils were α-pinene (19.40–23.54%), limonene (10.94–12.37%), 1,8-cineole (21.77–33.63%), and myrtenyl acetate (16.06–16.08%). As there were some differences between the chemical composition of these oils, the origin of these differences are discussed.

Tigecycline is the first of a new class of antibiotics named glycylcyclines and it was approved for the treatment of complicated intra-abdominal infections and complicated skin and skin structure infections. Notwithstanding this, tigecycline's pharmacological and microbiological profile which includes multidrug-resistant pathogens encourages physicians' use of the drug in other infections. We analyzed, during the first months after its launch, the tigecycline prescriptions for 113 patients in 12 institutions. Twenty-five patients (22%) received tigecycline for approved indications, and 88 (78%) for "off label" indications (56% with scientific support and 22% with limited or without any scientific support). The most frequent "off label" use was ventilator associated pneumonia (VAP) (63 patients). The etiology of infections was established in 105 patients (93%). MDR-Acinetobacter spp. was the microorganism most frequently isolated (50% of the cases). Overall, attending physicians reported clinical success in 86 of the 113 patients (76%). Our study shows that the "off label" use of tigecycline is frequent, especially in VAP. due to MDR-Acinetobacter spp., where the therapeutic options are limited (eg: colistin). Physicians must evaluate the benefits/risks of using this antibiotic for indications that lack rigorous scientific support.

Two hundred and fifty-three farmers and forest workers and 249 clerks from south-west Sweden were recruited to a cross-sectional seroprevalence study to find out if individuals working outdoors are more prone to acquire Borrelia burgdorferi infection than indoor workers and to find undiagnosed cases of Lyme borreliosis. The participants answered a questionnaire and blood specimens were collected to estimate the prevalence of antibodies to B. burgdorferi in each group. Sera were analysed with an enzyme-linked immunoassay technique to determine IgG antibodies to B. burgdorferi flagellum. The prevalence of B. burgdorferi antibodies was 7.6% in the farmers and forest workers vs. 5.3% in the clerks (adjusted odds ratio [age, sex] = 1.2 [95% confidence interval = 0.5-2.8]). One case of Lyme borreliosis was diagnosed. The positive predictive value of the antibody test was estimated to be 3% in the studied populations. B. burgdorferi infection is of low endemicity in south-west Sweden and is probably not an occupational risk among outdoor workers. Undiagnosed cases of Lyme borreliosis are uncommon. The test used is not acceptable for screening purposes.

OBJECTIVE: A suicide attempt is an established risk factor for subsequent suicide attempts and suicide. Nonetheless, the prediction of future suicidal behavior is poor. The lethality of previous suicidal behavior may be informative to better understand future suicide risk among patients hospitalized for suicidal thoughts and behavior. The current study examined whether the lethality of patients' index (most recent suicidal episode at hospitalization), first, and worst suicidal episode predicts the lethality of one's most lethal suicide attempt during a 2-year follow-up period. METHOD: A total of 98 patients hospitalized at an emergency department for high suicide risk (i.e., acute suicidal ideation or a suicide attempt) were included in the study. RESULTS: Results indicated that the lethality of the index suicidal episode predicted the lethality of the worst suicide attempt during a 2-year follow-up period. CONCLUSIONS: These findings extend a growing literature examining risk factors that influence the progression toward high lethality suicidal behavior.

OBJECTIVES: To report 3 new cases of akinetic mutism, a clinical syndrome defined by silent immobility with preserved visual alertness not accountable by lesion of the areas and/or effector pathways of speech and voluntary movements. MATERIAL AND METHODS: Anatomopathological studies were performed in Cases 1 and 2; clinical follow-up, EEG, angiography and CT scans in Case 3. RESULTS: Case 1: Bipallidal necrosis; Case 2: Left pallidal necrosis with right frontoparietal cortico-subcortical infarction; Case 3: Striato-capsular infarction on the left side, involving the caudate nucleus and the anterior arm of the internal capsule, together with obstructive hydrocephalus. CONCLUSION: The roles of both globus pallidus and prefrontostriatal circuits in the onset of voluntary movements are discussed.

In the era of evidence-based medicine, "treatment as usual" (TAU) for borderline personality disorder (BPD) is often considered ineffective or even iatrogenic. To evaluate the effects of TAU, this meta-analysis examined published data from the TAU arms of randomized controlled trials of manualized psychotherapies for BPD. Studies were selected through a comprehensive bibliographic search. A total of 16 studies met inclusion criteria. Comprehensive Meta-analysis V3 software was used for computing and pooling effect sizes. For the primary outcome category of BPD symptoms, Hedges' g showed a small-to-moderate improvement for patients in TAU conditions (11 studies; g = 0.371; 95% confidence intervals [CI: 0.246, 0.495]). Secondary outcomes included general psychopathology, global functioning, and self-harm/suicidality. Hedges' g indicated small improvements in general psychopathology (14 studies; g = 0.119; 95% CI [0.025, 0.214]) and global functioning (10 studies; g = 0.254; 95% CI [0.123, 0.384]). No significant effect was found for changes in self-harm/suicidality (four studies; g = 0.003; 95% CI [-0.193, 0.199]). These findings question the notion that TAU for BPD is inherently iatrogenic. Thus, in the absence of specialized treatment for BPD, standard available care may be a practical option. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

OBJECTIVE: To evaluate the incidence of suicidal outcomes and risk factors for short- and long-term recurrence of suicidal behavior (SB) among high-risk borderline personality disorder (BPD) patients during a 24-month prospective follow-up period. METHODS: A multicenter prospective cohort study was designed to compare data obtained from 136 patients admitted to the emergency department for current suicidal ideation (SI) or a recent suicide attempt (SA). Subjects were clinically evaluated and monitored for a new SA or suicide. RESULTS: The incidence of a new SA was 25.63 events/100 persons-year, and one patient died by suicide. Child sexual abuse (CSA) was the only significant predictor throughout the complete follow-up period. The absence of prior psychiatric treatment predicts the recurrence of SB in the first 6 months of follow-up. Patient age, poor psychosocial functioning before hospitalization, age at first SA, and having multiple suicide attempts increased risk of SB recurrence at the long-term period (24th months). In addition, there was an interaction between CSA and poor psychosocial functioning that increased risk of SB. CONCLUSION: The risk of recurrence was higher during the first 6 months. Risk factors at 6 and 24 months vary. These findings are important for implementing suicide strategies.

We report the clinical, SPET, immunohistochemical and DNA features of an early-onset familial Alzheimer's disease (FAD) in an Argentine pedigree of South American indian ethnic background. Pedigree spans 5 generations comprising more than 110 biological relatives. Clinical data supported the diagnosis of early onset FAD (mean age at onset 38.9 years) in 10 family members, including 3 with pathological confirmation (mean age at death 48.5). The pattern of transmission suggested autosomal dominant inheritance. Prominent features were mood changes, early language impairment, myoclonus, seizures and cerebellar signs. SPET displayed bilateral frontal, temporo-parietal and cerebellar hypoperfusion in early stages and in an asymptomatic member at risk, suggesting that SPET may have predictive value in this family. Immunohistochemistry showed beta amyloid deposits within neuritic plaques and vessel walls and no anti-PrP immunoreactivity. DNA analysis showed no abnormalities in the beta amyloid precursor protein gene. The identification of additional genetic defects in well characterized independent FAD pedigrees will contribute to the understanding of the pathogenesis of Alzheimer's disease.

The new antidepressant nomifensin (Hoechst 36984), a drug which showed less cardiotoxicity than tricyclics, was compared in a single-blind comparative trial with viloxazine. Forty elderly depressed patients were treated during four weeks. Nomifensin, N=21, 75 mg/day; viloxazine, N=19, 150 mg/day). Antidepressant effects were assessed by the Hamilton Rating Scale (HRS) for depression, and physical disability, by the Northwestern University Disability Scales. The HRS disclosed statistically significant improvement with both treatments. However, the scores in the nomifensin group fell distinctly form the second week on (P less than 0.01). There were no side effects reported spontaneously by the patients. Sinus tachycardia was recorded in two instances (one viloxazine and one nomifensin patient).

MS INTA 416 is a hard red winter wheat selected for high yield potential and good bread-making quality, combined with moderate resistance to Fusarium-head-blight and high resistance to leaf-rust, due mainly to presence of resistance genes Fhb1 and Lr47. MS INTA 416 is adapted to main production areas of Central-Argentina.

OBJECTIVE: The serotonin-transporter-linked polymorphic region (5-HTTLPR) polymorphisms are associated with suicidal behavior; however, prospective studies are scarce. Herein we aim to determine if 5-HTTLPR polymorphisms predict risk of short-term suicide reattempt in a high-risk suicidal sample. We also explore possible mediators or moderators of this relationship. METHODS: A multicenter prospective cohort study was designed to compare data obtained form 136 patients admitted to the emergency department for current suicidal ideation or a recent suicide attempt. Subjects were clinically evaluated, genotyped, and monitored for a new suicide attempt for 6 months. RESULTS: At 6 months of follow up, 21% of the subjects had a new suicide attempt. The frequency of L-allele and L-carrier was higher in reattempters when compared with non-reattempters (55.8% vs. 35.4%, p = 0.01 and 76.9% vs. 54.2%, p = 0.04, respectively). Reattempters also differ from non-reattempters patients with respect to age, history of previous suicide attempts, and age of onset of suicidal behavior. The logistic regression model showed that L-carriers had an odds ratio of 2.8 (95% CI: 1.0-7.6) for reattempts when compared to SS genotype. The adjusted model indicates that this association is not mediated or moderated by impulsivity. CONCLUSION: The 5-HTTLPR polymorphisms predicted short-term risk of suicidal reattempt independently of age and sex. L-carriers have almost three times more risk of relapse when compared with SS carriers.

Despite the great effort to raise awareness among health promotion, nowadays Public Health policies are not often recognized as important tools. For this reason, the Health in All Policies (HiAP) approach is instrumental in tackling this information gap. In 2018, the US Association of Schools and Programs of Public Health (ASPPH) launched an international campaign called "This is Public Health" (TIPH), whose aim was "to brand public health and raise awareness of how it affects individuals, communities and populations". The Association of Schools of Public Health in the European Region (ASPHER), in coordination with ASPPH, decided to create a European campaign to support and to reproduce the American one, by opening a challenge among the European Public Health Schools. The Schools and Programs of PH of Vita-Salute "San Raffaele" University, Milan, University of Parma, University of Pavia and Politecnico of Milan won this bid. In this "briefing on" we present a report on the Italian project for raising awareness of Public Health among general population and health care personell.
