Abstract
OBJECTIVE Analyze the molecular mimicry between Plasmodium spp. and autoantigens associated with GBS, identifying possible antigenic epitopes. METHODS PSI-Blast, Praline, Emboss, Protein Data Bank, Swiss Model Server, AlphaFold 2, Ellipro and PyMol 2.3 were used to search for homologies, perform alignments, obtain protein structures, and predict epitopes. RESULTS 17 autoantigens and seven immunological targets of the peripheral nervous system were included, identifying 72 possible epitopes associated with GBS. From the proteome of Plasmodium spp. (298 proteins), only two showed similarities close to 30% with TRIM21 and BACE1, generating seven possible epitopes. CONCLUSION No significant homologies were observed between the proteome of GBS and Plasmodium spp. The exploration of other mechanisms such as immune-mediated capillary damage, Epitope Spreading or Bystander Activation is suggested to explain the mentioned association. These findings underscore the need to clarify the etiology of autoimmune diseases and the role of pathogens. The need for experimental studies to validate these results is emphasized.

Abstract
Despite its potential impor- tance for adherence, knowledge of the treatment has been little studied in patients with psychosis. We performed this study to assess the possible association between knowledge of the treatment and nonadherence, unintentional nonad- herence (UNA) and intentional nonadherence (INA).

Abstract
Introduction
Leadless pacemakers (LPM) have demonstrated adequate electrical performance and safety in patients with multiple commorbidities such as heart valve replacements at short-term follow-up.
Purpose
We present our experience in patients with LPM and heart valve replacements at long-term follow-up.
Methods
This was a prospective observational study including all consecutive LPM implantation from June 1 2005 to March 15 2021. Clinical, electrical, echocardiographic characteristics, related complications and electrical parameters were compared in 2 different groups with and with-out valve surgical procedure.
Results
A total of 255 LPM were implanted. Clinical, electrical and echocardiographic characteristics are described in table 1. Mean follow-up was of 24 months. There were no significant differences in electrical performance or related complications in between both groups (Figure 1).
Conclusions
Electrical performance and complications were no significantly different between both groups with and without heart valve replacements.

Abstract
BACKGROUND Despite a wealth of studies seeking to identify factors associated with nonadherence few consistent predictors have been determined, and several gaps still exist in the literature. METHOD We assessed 110 consecutively admitted patients diagnosed with schizophrenia or schizoaffective disorder according to ICD-10 criteria. Assessments were performed during hospitalization and at six-months follow-up. Evaluation included sociodemographic, clinical, psychopathologic and treatment-related variables. Prevalence of nonadherence, associated variables, reasons for nonadherence and possible subtypes were explored. Adherence was defined as the concurrence of adherence to antipsychotic treatment and adherence to outpatient follow-up, during the six-month period. RESULTS Nonadherence was detected in 58.2% of patients. An identifiable profile was found in nonadherent patients. After multivariate logistic regression analysis, low socio-economic level (OR = 3.68; 95% CI = 1.42-9.53), current cannabis use or abuse (OR = 2.79; 95% CI = 1.07-7.28), nonadherence as a reason for relapse and admission (OR = 5.46; 95% CI = 2.00-14.90), and greater overall severity of symptoms at six months follow-up (OR = 2.00; 95% CI = 1.02-3.95) remained independently associated with nonadherence. Believing that medication is unnecessary was the most reported reason for nonadherence. For nonadherent patients (N = 64), two distinguishable subtypes were found: intentional nonadherence (N = 32; 50%), and unintentional nonadherence (N = 32; 50%). CONCLUSIONS A large percentage of patients with schizophrenia or schizoaffective disorder did not adhere to their treatment in the post-discharge follow-up period. The profile identified may enable better prevention of this problem. Specific reasons for nonadherence should also be explored to provide individualized strategies.

Abstract
BACKGROUND Nonadherence is a major problem in the treatment of psychotic disorders. It has been hypothesized that nonadherent patients with schizophrenia are not a homogeneous population and subtypes of nonadherence might exist, but this hypothesis has not been specifically tested.
AIM To test the hypothesis of subtypes of nonadherence in schizophrenia and schizoaffective disorder.
METHODS This prospective study included 110 consecutively admitted patients diagnosed with schizophrenia or schizoaffective disorder. Assessments were performed at baseline and at 6 mo follow-up after discharge. Sociodemographic, clinical, psychopathological and treatment-related variables were evaluated. Adherence was defined as the concurrence of adherence to antipsychotic treatment and outpatient follow-up during the six-month period. Adherence to antipsychotic treatment was defined as the concurrence of objective and subjective adherence. Sixty-four patients (58%) fulfilled nonadherence criteria at the end of the follow-up period and were categorized according to their subtype of nonadherence.
RESULTS In nonadherent patients (n = 64), 32 (50%) fulfilled criteria of intentional nonadherence, and 32 (50%) of unintentional nonadherence (UNA). Unintentional nonadherent patients, as compared to intentional nonadherent patients, are characterized by older age, lower educational level, worse cognitive and negative symptoms, greater severity, worse knowledge of their treatment regimen, greater prevalence of supervision of the treatment, lower number of prior hospitalizations and greater use of nonpsychiatric treatment, anticholinergics and hypnotics. Low educational level (OR = 26.1; 95%CI: 2.819-241), worse treatment knowledge at six months (OR per unit = 0.904; 95%CI: 0.853-0.957) and nonpsychiatric treatment at six months (OR = 15.8; 95%CI: 1.790-139) were independently associated to UNA.
CONCLUSION Differentiated subtypes of nonadherence according to intentionality seem to exist in patients with schizophrenia and schizoaffective disorder. Our findings suggest the need for differentiated approach, both in future research and in clinical practice.

Abstract
AIM The aim of this study was to evaluate the efficacy of transcutaneous neuromodulation of the posterior tibial nerve for faecal incontinence and to assess quality of life after the procedure. METHOD A prospective non-randomized cohort study was conducted in a tertiary centre from September 2010 to May 2013. All patients with faecal incontinence who met the inclusion criteria were included and were treated as outpatients during a 3-month period by unilateral neuromodulation of the posterior tibial nerve. The patients were followed 3-monthly for 1 year. Severity scales, a bowel diary and quality of life scales were evaluated prospectively before and after treatment. RESULTS Twenty-seven patients of median age 67 (interquartile range 60-69) years and a male to female ratio of 1/6 were included. Faecal incontinence was for solid stools in 48.1% of patients with urgency in 55.6%. About one-third (34.6%) had a sphincter defect on ultrasound and reduction of anal canal pressure in 85.2%. There was a significant improvement in episodes of incontinence on the Wexner score and visual analogue scale assessment and a decrease in the number of episodes of incontinence per unit time. The Fecal Incontinence Quality of Life score was improved at the end of the follow-up. No adverse effects were observed. The cost of the treatment was €135 per patient. CONCLUSION Transcutaneous posterior tibial nerve neuromodulation provides good treatment for faecal incontinence in terms of efficacy and quality of life.

Abstract
OBJECTIVE Attempted suicide and death due to suicide are not uncommon among patients with bipolar disorder. Although some risk factors for suicidality in bipolar patients have been identified, little is known about hopelessness and other possible trait or diathesis-related factors. Consequently, the objective of this study was to investigate variables associated with suicidal risk in clinically nonsyndromal bipolar patients. METHODS A sample of 102 outpatients with a diagnosis of bipolar disorder according to International Classification of Diseases, 10th Revision criteria during nonsyndromal stage were evaluated. On the basis of suicidal history, patients were divided into suicide attempt, suicidal ideation, and nonsuicidal groups. Sociodemographic, clinical, and psychopathological variables were assessed. RESULTS As compared with the nonsuicidal group, female sex, combined psychopharmacologic treatment, and hopelessness were independently associated with suicide attempt. Hopelessness and insight into having a mental disorder were independently associated with history of suicidal ideation. CONCLUSIONS Patients with bipolar disorder and suicidal history are characterized by the presence of hopelessness, which probably confers greater vulnerability for suicidal behavior in the presence of stress factors. This identification of the risk profile for suicidal behavior in nonsyndromal bipolar patients adds complementary information to risk factors established for suicidality during acute phases of the disease, allows for differentiated preventive and treatment approaches of patients at risk, and suggests psychotherapy as an advisable intervention in this group of patients.

Abstract
The angular dependence of the magnetoresistance effect has been measured on bicrystalline La(0.75)Sr(0.25)MnO(3) films. The measurements have been performed on an electronically lithographed Wheatstone bridge. The study of the angular dependence of both the magnetoresistance and the resistance of single-crystalline and grain-boundary regions of the samples allowed us to isolate two contributions of low-field magnetoresistance in manganites. One of them is associated with the spin-orbit effect, i.e. the anisotropic magnetoresistance of ferromagnetic compounds, and the other one is related to spin-disorder regions at the grain boundary. Complementary x-ray diffraction, ferromagnetic resonance and low temperature magnetization experiments contribute to the characterization of the magnetic anisotropy of the samples and the general comprehension of the problem.

Abstract
The voltammetric behaviour and amperometric detection of tetracycline (TC) antibiotics at multi-wall carbon nanotube modified glassy carbon electrodes (MWCNT-GCE) are reported. Cyclic voltammograms of TCs showed enhanced oxidation responses at the MWCNT-GCE with respect to the bare GCE, attributable to the increased active electrode surface area. Hydrodynamic voltammograms obtained by flow-injection with amperometric detection at the MWCNT-GCE led us to select a potential value E(det) = +1.20 V. The repeatability of the amperometric responses was much better than that achieved with bare GCE (RSD ranged from 7 to 12%), with RSD values for i (p) of around 3%, thus demonstrating the antifouling capability of MWCNT modified electrodes. An HPLC method with amperometric electrochemical detection (ED) at the MWCNT-GCE was developed for tetracycline, oxytetracycline (OTC), chlortetracycline and doxycycline (DC). A mobile phase consisting of 18:82 acetonitrile/0.05 mol L(-1) phosphate buffer of pH 2.5 was selected. The limits of detection ranged from 0.09 micromol L(-1) for OTC to 0.44 micromol L(-1) for DC. The possibility to carry out multiresidue analysis is demonstrated. The HPLC-ED/MWCNT-GCE method was applied to the analysis of fish farm pool water and underground well water samples spiked with the four TCs at 2.0 x 10(-7) mol L(-1). Solid-phase extraction was accomplished for the preconcentration of the analytes and clean-up of the samples. Recoveries ranged from 87 +/- 6 to 99 +/- 3%. Under preconcentration conditions, limits of detection in the water samples were between 0.50 and 3.10 ng mL(-1).

Abstract
Opioid receptors have been localized to a number of brain regions in rats as well as in other species. In situ hybridization has demonstrated the presence of mRNA for the delta receptor subtype in adult rat cerebellar cortex and in several deep nuclei, but there are no reports on localization of the delta receptor protein in cerebellar regions. In the present study, both quantitative immunohistochemistry and Western blots reveal the presence of delta receptors in the adult rat cerebellum, using a specific affinity-purified antibody. Purkinje cells and processes, as well as cells in the granule cell layer, were positively stained with the antibody. Quantitation of confocal microscopy images illustrated a lower relative level of delta receptor immunoreactivity in cerebellar cortical neurons as compared to neurons in hippocampal regions, striatum and cerebral cortex. Stimulation of delta receptors with a selective agonist, DPDPE, in frozen sections of rat brain, induced a significant increase in binding of [35S]-GTPgammaS in the cerebellar cortex as compared to basal binding levels, thereby demonstrating coupling of the receptor subtype to G-protein. Functional implications for the delta receptor in the cerebellum are discussed, particularly in light of evidence for the presence of a cerebellar opioid receptor for the endogenous opioid methionine enkephalin during early postnatal life.

Abstract
The objective of this study was to analyze the long-term outcome of 51 patients with brachial-jugular grafts for dialysis. Age, presence of diabetic nephropathy, complications of the angio-access, and therapeutic methods of treating complications were analyzed. All surgical procedures were performed under local anesthesia in an ambulatory surgical setting. The duration of angio-access was analyzed using the life-table method. Our results showed that brachial-jugular grafts can be performed under local anesthesia and in an ambulatory surgical setting. This procedure can be an alternative to complex intrathoracic procedures, Dacron cuff catheters, or lower limb grafts, in cases of stenosis or occlusion of the subclavian vein.

Abstract
The title compound, raloxifene hydrochloride, C(28)H(28)NO(4)S(+).-Cl(-), belongs to the benzothiophene class of antiosteoporotic drugs. In the molecular cation, the 2-phenol ring sustains a dihedral angle of 45.3 (1) degrees relative to the benzo[b]thiophene system. The benzo[b]thiophene and phenyl ring planes are twisted with respect to the carbonyl plane, with the smallest twist component occurring between the phenyl and carbonyl planes. The N atom bears the positive charge in the molecular cation and the piperidine ring adopts an almost perfect chair conformation. The Cl(-) anion is involved in the formation of N-H...Cl and O-H...Cl intermolecular hydrogen bonds, which lead to the formation of a layer of molecular cations.

The title compound, 11-chloro-8,12b-dihydro-2,8-dimethyl-12b-phenyl-4H-[1,3]oxazino[3,2-d][1,4]benzodiazepine-4,7(6H)-dione, C20H17ClN2O3, is a benzodiazepine with an additional d-face-fused heterocyclic ring. In the molecule, a dihedral angle of 86.2 (1) degrees is formed by the planes of the phenyl and benzo rings and the former is axially oriented from the core, i.e. the fused 6,7,6-tricyclic system. Both heterocycles in the core suffer significant deviations from planarity. The central diazepine ring is a twist-boat and the oxazine ring exhibits a conformation intermediate between half-chair and sofa.

Abstract
BACKGROUND The need for continued surveillance endomyocardial biopsies beyond the first year after cardiac transplantation is controversial. We evaluated the incidence of rejections requiring treatment (International Society Heart and Lung Transplantation grade 3A or greater) in patients 5 years or more after heart transplantation. METHODS We conducted a retrospective chart review of all patients who underwent at least 1 endomyocardial biopsy at our center 5 years or more after heart transplantation. RESULTS A total of 461 biopsies were performed in 77 patients 5 or more years after heart transplantation. Nine episodes of grade 3A or greater rejection were identified in 8 of 77 patients (10%). During the first year, 7.6% of biopsies were grade 3A or greater. Grade 3A rejection occurred in approximately 3.5% to 4% of biopsies during years 2 to 7. The overall incidence of procedural related complications at our institution was < 0.5%. CONCLUSION Endomyocardial biopsies continue to detect clinically significant rejection beyond 5 years after cardiac transplantation. The overall incidence of procedural related complications requiring treatment was low and none was life threatening. The absence of early rejection does not predict freedom from late rejection. Therefore, we continue to recommend surveillance biopsies in cardiac transplant recipients late after transplantation.

Abstract
This paper reports laboratory studies of the behavior and fate of triflusulfuron-methyl in aqueous buffer and soils. Aqueous hydrolysis was pH-dependent and fast in acidic buffer solutions. In basic buffers, the hydrolysis rate variation was low between pH 7 and pH 10. The degradation pathway in the range of pH 4-10 was via cleavage of the sulfonylurea bridge to form two transformation products: 2-amino-4-(dimethylamino)-6-(2,2,2-trifluoroethoxy)-1,3, 5-triazine (2) and 6-methyl-2-methylcarboxylate benzene sulfonamide (3). Comparison of transformation rates in sterile and nonsterile soils indicates that chemical and microbial processes are important in soil degradation. The former is more important in acidic soils, and the latter is more important in basic soils. A biphasic model fits well with dissipation of triflusulfuron-methyl in soil. The triazine formed during the first step of transformation was degraded more rapidly in basic soils than in acidic soils.

Abstract
INTRODUCTION The main objective of antibiotic prophylaxis in surgery is to reduce morbidity and mortality associated with wound infection, which has a favorable impact on quality of care and overall health-care costs. The bases of antibiotic prophylaxis have been known for decades, but the appearance of new pharmacological agents, alternative routes of administration, modern surgical procedures, and previously unknown antimicrobial resistances involve the need for reviewing these bases. OBJECTIVE To re-evaluate some of the general principles of the use of antibiotic prophylaxis in surgery and highlight the quality of the evidence supporting our clinical decisions found in the literature. METHOD Review of the literature with special attention to prospective, randomized, evidence-based clinical trials on the need for antibiotic prophylaxis in surgery, mainly general surgery. RESULTS The method for demonstrating the effectiveness of an antibiotic in prophylaxis continues to be the prospective, randomized clinical trial. Evidence of the need for antibiotic prophylaxis in clean-contaminated surgery and when prosthetic materials are used is good. CONCLUSIONS Most studies on the general principles of prophylaxis have been carried out in general surgery and it is difficult to extrapolate their results to other fields or surgical specialties. Therefore, new clinical trials in each specialty are needed to establish specific recommendations. However, the standardization of aseptic, antiseptic, and technical procedures in surgery has produced a notable decrease in the wound infection rate compared to historical controls, so now it is difficult to demonstrate significant differences in the results of clinical trials. Finally, the response to the fundamental question of "What do we propose to prevent and to what degree?" with which the antibiotic era began is either difficult to formulate or described ambiguously when referring to advanced procedures, such as endoprostheses, endoscopic retrograde cholangiography, or dental implants.

Abstract
We assessed the bronchodilating effect of glycopyrrolate (GP) and compared it with that of metaproterenol (MP), alone and in combination (GP+MP), in patients with chronic obstructive pulmonary disease (COPD). In a double-blind study, 11 patients (aged (mean +/- SD) 69 +/- 6 yrs; forced expiratory volume in one second (FEV1) 1.2 +/- 0.4 L) with stable COPD inhaled nebulized GP 1.0 mg, MP 15 mg, or GP 1.0 mg+MP 15 mg. Spirometry was performed before inhalation and at hourly intervals for 8 h after inhalation. It was found that GP produced a bronchodilating effect that was about equal to that of MP but lasted longer (8 vs 5 h). The combination of GP and MP produced a bronchodilating effect that was greater than that of either drug alone and was evident mostly during the effect of MP. The mean peak percentage improvement in FEV1 over baseline was 35% for GP+MP and 25% for either drug alone. These data suggest that nebulized glycopyrrolate is an effective bronchodilator in some patients with chronic obstructive pulmonary disease. Concurrent administration of glycopyrrolate and metaproterenol produces additional bronchodilation that is primarily apparent during the bronchodilator effect of metaproterenol.

Abstract
A bacterial strain able to transform iprodione was isolated from a fast iprodione-degrading soil by enrichment procedures. Transformation was detected through 3,5-dichloroaniline production as measured by a rapid colorimetric method. The strain, MA6, was tentatively identified as an Arthrobacter sp. When it was incubated with MA6 in a minimum mineral medium (pH 6.5), iprodione (8.8 mumol/liter) was transformed into two major metabolites that were identified by high-performance liquid chromatography analysis: 3,5-dichlorophenylcarboximide (metabolite 1) and (3,5-dichlorophenylurea) acetic acid (metabolite 2), which was produced after ring cleavage of the former product. These products were synthesized in the laboratory and compared with metabolites 1 and 2 which were formed during iprodione degradation. Small quantities of 3,5-dichloroaniline also appeared in the bacterial culture but did not substantially increase between the first and second days of incubation. In contrast, in the sterile control medium, iprodione was spontaneously transformed into hydantoic acid and an iprodione isomer. Chemical and biological transformations of iprodione seem to occur through two different pathways. One biological degradation pathway is proposed.
