A systematic review of barriers to accessing cleft care worldwide.

PURPOSE: Patients with cleft lip/palate need an interdisciplinary approach. Delays in the care of these patients and difficulties in accessing health services have been reported in different low-, middle-, and high-income countries. This study aimed to characterize worldwide publications on access to cleft lip and palate health treatment. METHODS: Databases were selected systematically and searched until July 2021. The review process followed standard methods for systematic reviews. The study quality was evaluated using the Strengthening the Reporting of Observational studies in Epidemiology guidelines for observational studies. RESULTS: A total of 289 publications were identified using our search strategy. After reviewing the titles and reading the abstracts and full text, 16 studies met the inclusion criteria in the review. In one study, financial difficulties obtained the attention of the professionals who attended to cleft lip/palate patients. Ethnic disparities, problems in transportation, and long distances between users and health centers were found. Additionally, there was misinformation about treatment and follow-up among the caregivers of patients with cleft lip/palate. CONCLUSION: When reviewing the literature on access to health services for patients with cleft lip/palate, barriers were reported in access to information, physical access to care centers, financial resources to cover expenses for treatment, and opportunities in care.

Ocular Manifestations Related to Antibodies Positivity and Inflammatory Biomarkers in a Rheumatological Cohort.

Purpose: Ocular involvement is frequent in autoimmune diseases and even can be the first manifestation. There are multiple descriptions in the literature around the world regarding this topic. However, we evidenced a lack of studies analyzing the relationship between the ocular manifestations and systemic biomarkers, especially in Latinamerica. Therefore, this study aimed to examine the relationship between the positivity of inflammatory biomarkers and the ocular manifestations in a Colombian cohort of rheumatological patients. Patients and Methods: We conducted an observational, descriptive, non-comparative cross-sectional study in a rheumatology center, in Bogotá, Colombia, from 2013 to 2019. We calculated a sample size of 797 patients to assess the prevalence of ocular manifestations and inflammatory biomarkers. We performed univariate analyses for categorical and continuous variables and bivariate analyses using the Chi-square and Fisher's exact test for categorical variables. Results: Women represented 84% of the population, and the mean age was 54.61± 15.64 years. Of 797 patients, 21.45% reported one or more ophthalmological diagnoses, being keratoconjunctivitis sicca (KCS) the most common (15.93%), followed by uveitis, and cataract (1.38%, each one). Regarding ophthalmological symptoms, 35% presented at least one, being dry eye sensation (DE) the most common (30.86%), followed by ocular pain (2.76%), red eye, and decreased visual acuity (2.63%, each one). The antibodies or inflammatory biomarkers most frequently found were antinuclear antibodies (ANAs) (35.3%), C-reactive protein (28.7%), and rheumatoid factor (27.9%). We found statistical associations between consumption of complement 3, anti-CCP, anti-RO, and anti-LA antibodies with ocular manifestations such as photophobia, DE, conjunctivitis, KCS, uveitis, retinal vasculitis, and maculopathy. Conclusion: Ocular manifestations are frequently found in patients with positive antibodies and inflammatory biomarkers. Our results suggest antibodies and inflammatory molecules could be biomarkers for ocular manifestations in patients with rheumatological diseases. This study provides the basis for future longitudinal studies.

Psychometric Properties of a Cultural Adapted Version of the Assessment of Identity Development in Adolescence in Panama.

The Assessment of Identity Development in Adolescence (AIDA) is a self-report instrument to detect pathological development of Identity. In Panamá, psychometric instruments for assessment of psychopathology in adolescence are lacking. Our aim was to develop a valid and reliable version of the AIDA Inventory for Panamanian Population. AIDA was adapted to Spanish considering cultural aspects of Panamanian population. Two pilot tests were performed prior to main test to assess item-total correlation at subscale, primary scale and total scale levels and internal consistency at subscale level. A mixed sample of students and PD patients (N = 315) completed the AIDA inventory, the "Strength and Difficulties Questionnaire" and "Defense Style Questionnaire-40." AIDA was retested in a sub sample from school population (n = 98). The Structured Clinical Interview for Axis II Disorders was used for diagnosis of personality disorders in the patient sample (n = 25). Psychometric properties were tested to assess internal consistency, reliability, factorial validity, convergent validity, and criterion validity. AIDA Panama showed excellent internal consistency for the total scale Identity Diffusion with Cronbach's α:0.94 and a retest reliability of 0.84. A Bifactorial CFA was modeled to assess the dimensionality of the inventory. The proportion between OmegaH and Omega at total scales 96% of the variance is explained by a general factor. Furthermore, the Explained Common Variance for the General Factor is 73% supporting unidimensionality. In line with theory, AIDA total scale showed a high positive correlation (r = 0.67) with Total Difficulties scale and high positive correlation (r = 0.71) with Immature Defense scale. The AIDA total score differed highly significant (p = 0.000) between the patient sample and the students with a large effect size (d = 1.02). Conclusion: The adaptation and validation of AIDA for Panamanian adolescent population was successful with good psychometric properties and significant correlations with related psychopathological constructs. AIDA showed high clinical validity by providing a valid discrimination between the school sample and a diagnosed PD sample, in line with the assumption that impaired identity functioning is at the core of personality disorders, especially in adolescence.

Colecistitis aguda durante el segundo trimestre del embarazo: reporte de un caso / Acute cholecystitis during the second trimester of pregnancy: A case report

Resumen ANTECEDENTES: La colecistitis aguda es la segunda causa más frecuente de urgencia quirúrgica no obstétrica, con una incidencia de 1 caso por cada 1600 a 10,000 embarazos. OBJETIVO: Reportar el caso de una paciente con colecistitis aguda durante el segundo trimestre del embarazo tratada mediante cirugía laparoscópica. CASO CLÍNICO: Paciente de 34 años, con 16.5 semanas de embarazo. Acudió a consulta debido a un dolor abdominal de tipo cólico en el hipocondrio derecho. A la exploración física se encontraron: abdomen blando, depresible, dolor a la palpación en el flanco e hipocondrio derechos, signo de Murphy negativo, sin datos de irritación peritoneal; no se palparon plastrones; el útero se encontraba arriba de la sínfisis del pubis. El ultrasonido abdominal mostró la vesícula debidamente delimitada, con bordes regulares y definidos, con pared delgada y múltiples cálculos en su interior. No se evidenció leucocitosis. Los reportes de la laparoscopia fueron: vesícula con paredes a tensión, el conducto cístico corto, dilatado, con un cálculo retenido. No se informaron complicaciones. La paciente fue dada de alta a las 48 horas del posoperatorio. Continuó en control prenatal y finalizó el embarazo por cesárea. El desenlace neonatal fue satisfactorio. CONCLUSIONES: La colecistitis es una de las principales alteraciones durante el embarazo. Postergar la cirugía supone consecuencias para la madre y el feto, por lo que debe establecerse el diagnóstico y tratamiento oportunos.

Abstract BACKGROUND: Bile duct pathologies, specifically acute cholecystitis, is the second most common cause of non-obstetric surgical emergency, with an incidence of 1 in 1,600 to 10,000 pregnancies. OBJECTIVE: Report of a case of a patient with acute cholecystitis during the second trimester of pregnancy treated by laparoscopic surgery. CLINICAL CASE: 34-year-old female, pregnancy 3, childbirth 2; with pregnancy of 16.5 weeks. She presented colicky abdominal pain located in the right upper quadrant. Physical examination revealed abdomen with normoaudible peristalsis, soft, depressible, pain on medium and deep palpation in the right hypochondrium, murphy sign (-), no evidence of peritoneal irritation, no plastrons palpated, uterus above symphysis of the pubis. Abdominal ultrasound reports a well-defined vesicle with regular and well-defined borders, with a thin wall, with the presence of multiple stones in its interior. There was no presence of leukocytosis. Laparoscopic surgical management was decided, during which a gallbladder with tension walls, a short, dilated cystic duct, with an impacted stone was found. No complications were reported. She continued her prenatal care in our hospital unit and the pregnancy was resolved by cesarean section. Neonatal outcomes were optimal. CONCLUSIONS: Cholecystitis is one of the main non-obstetric surgical pathologies that occur in pregnancy, it is important to consider that the fact of postponing surgery could have consequences for both the mother and the fetus, so the timely diagnosis and management of this type of pathology must be carried out.

Leachate treatment: comparison of a bio-coagulant (Opuntia ficus mucilage) and conventional coagulants using multi-criteria decision analysis.

The main aim of this research was to compare a bio-coagulant, organic coagulant, and a conventional coagulant applied to the treatment of leachates. Coagulant options were Stage 1 FeCl3, Stage 2 Polyamine, and Stage 3 Opuntia ficus mucilage (OFM). Optimal conditions for maximum chemical oxygen demand (COD) removal were determined by experimental data and Response Surface Methodology. The application of Multiple Criteria Decision Analysis using Multi-Criteria Matrix (MCM) was explored by evaluating the Coagulation-Flocculation processes. Maximum COD removal (%) and the best MCM scores (on a scale from 0 to 100) were: Stage 1: 69.2±0.9 and 48.50, Stage 2: 37.8±1.1 and 79.0, and Stage 3: 71.1±1.7, and 81.5. Maximum COD removal using FeCl3 and OFM was not statistically different (p 0.15 < 0.05). OFM extraction process was evaluated (yield 0.70 ± 1.17%, carbohydrate content 32.6 ± 1.18%). MCM allows the evaluation of additional technical aspects, besides oxygen COD removal, as well as economic aspects, permitting a more comprehensive analysis. Significant COD removals indicate that the use of OFM as a coagulant in the treatment of stabilized leachate was effective. Opuntia ficus cladodes, a residue, were used to treat another residue (leachates).

Ocular Manifestations in Colombian Patients with Systemic Rheumatologic Diseases.

PURPOSE: To establish the prevalence of ocular involvement in a Colombian population with rheumatologic diseases. DESIGN: Observational cross-sectional study. METHODS: We included a probabilistic sample size of 797 patients who attended a rheumatologic disease center in Bogotá, Colombia. Statistical analysis with descriptive measures and Chi-square independence test between rheumatologic diseases and ophthalmological symptoms and diseases was performed. RESULTS: Eighty-four percent of the population were women, and the mean age was 54.61± 15.64 years. The most common condition was rheumatoid arthritis (33.37%), followed by fibromyalgia (22.71%), Sjögren Syndrome (19.72%), and systemic lupus erythematosus (9.91%). Almost 7% of the patients presented polyautoimmunity. Thirty-five percent of the patients reported one or more ophthalmological symptoms, being dry eye sensation the most common (30.86%), followed by ocular pain (2.76%), red-eye, and decreased visual acuity (both 2.63%). Similarly, 21.45% of the patients presented one or more ophthalmological diagnoses, being keratoconjunctivitis sicca the most common (15.93%), followed by cataract, uveitis (1.38% each), and scleritis (1.25%). CONCLUSION: Almost a third of the patients reported any ocular involvement. It is crucial to be aware of the most common ophthalmic manifestations among the different rheumatologic diseases in our population, to offer early specialist referral and timely treatment.

Damage control in orthopaedical and traumatology

In Orthopedics, damage control is indicated in patients with pelvic and/or long bone fractures associated with hemodynamic instability. It is inappropriate to perform a complex definitive reduction and fixation surgery for severely injured trauma patients with hemodynamic instability. In these cases, it is recommended to perform minimally invasive procedures that temporarily stabilize the fractures and bleeding control. Closed or open fractures of the long bones such as femur, tibia, humerus, and pelvis can lead to hemodynamic instability and shock. Thus, orthopedic damage control becomes a priority. However, if the patient is hemodynamically stable, it is recommended to stabilize all fractures with an early permanent internal fixation. These patients will have a shorter hospital length of stay and a reduction in mechanical ventilation, blood components transfusions and complications. Therefore, the concept of orthopedic damage control should be individualized according to the hemodynamic status and the severity of the injuries. Open fractures, dislocations, and vascular injuries could lead to permanent sequelae and complications if a correct management and approach are not performed.

En Ortopedia se indica control del daño en pacientes que presentan fracturas de pelvis y/o huesos largos asociado a condiciones generales inestables. Dada la severidad del trauma asociada a inestabilidad hemodinámica no es adecuado realizar una cirugía definitiva compleja de reducción y fijación de todas sus fracturas. En estos casos se recomienda realizar procedimientos poco invasivos que permitan estabilizar provisionalmente las fracturas, para; disminuir el dolor, controlar la hemorragia de las fracturas, obtener una alineación adecuada de los huesos fracturados y reducir las luxaciones. Estas medidas permiten controlar el daño del primer golpe para así disminuir las complicaciones. Las fracturas de los huesos largos fémur, tibia, húmero y pelvis cerradas o abiertas pueden llevar a una inestabilidad y estado de shock. Mientras que el paciente no tenga alteración hemodinámica, se recomienda estabilizar todas sus fracturas precozmente con una fijación interna que controle esta forma el daño y la necesidad de tiempo de hospitalización. Como resultado se disminuyen los días en cuidados intensivos, la ventilación mecánica, las transfusiones y las complicaciones. El concepto de control de daño para el manejo de las lesiones ortopédicas se debe individualizar de acuerdo a las condiciones generales de cada paciente y la gravedad de sus lesiones como: fracturas abiertas, luxaciones, luxación completa de la articulación sacroíliaca, luxofractura del talo, y lesiones vasculares, ya que estas lesiones requieren un manejo prioritario inicial generalmente definitivo en la mayoría de los pacientes con politraumatismo para evitar complicaciones serias futuras que pueden dejar secuelas definitivas al no recibir el tratamiento adecuado inicial.

Desenlaces materno-fetales en embarazadas con categoría de riesgo III - IV según la Organización Mundial de la Salud en un centro de tercer nivel durante 2006 a 2017 / Maternal-fetal outcomes in pregnant women with World Health Organisation risk category III - IV in a tertiary care centre from 2006 to 2017

Resumen Objetivo: describir los desenlaces materno-fetales en embarazadas con categoría de riesgo III-IV según la Organización Mundial de la Salud (OMS). Métodos: se revisaron las historias clínicas de 41 embarazadas con categoría de riesgo III-IV según la OMS, atendidas en un hospital de tercer nivel en Medellín, Colombia. Se recolectaron variables demográficas, clínicas y ecocardiográficas en un formulario diseñado para tal fin. Las variables primarias están orientadas a la evaluación de los desenlaces maternos y fetales. Los análisis estadísticos se realizaron con el software IBM-SPSS versión 23. Resultados: la tasa de eventos neonatales fue mayor que la tasa de eventos maternos (68.3 vs. 31.7%). Los desenlaces maternos primarios y secundarios ocurrieron en un 31.7 y 12.2% respectivamente. La distribución según la categoría de riesgo de la OMS fue del 7.3% en el grupo III y del 92.7% en el grupo IV. Solo hubo una muerte materna no relacionada con enfermedad cardiovascular. La presencia de insuficiencia tricuspídea moderada/severa se asoció con prematuridad (p 0.006) y las gestantes con presión sistólica pulmonar ≥ 50 mm Hg tuvieron mayor número de neonatos con distrés respiratorio (p 0.010). La falla cardiaca derecha se relacionó con muerte materna (p 0.014) y prematuridad (p 0.019), mientras que la de falla cardiaca izquierda se asoció con muerte neonatal (p 0.003). Conclusiones: la enfermedad cardiovascular materna es causa frecuente de alta morbilidad y mortalidad materno-fetal. Este estudio identificó los principales desenlaces maternos y fetales, sin embargo, se requieren estudios con mayor tamaño de muestra.

Abstract Objective: To describe the maternal-fetal outcomes in pregnant woman with risk classification of III-IV according to the World Health Organization (WHO). Methods: A review was carried out on the medical records of 41 pregnant women with WHO risk classification of III-IV, treated in a tertiary hospital in Medellin, Colombia. Demographic, clinical, and cardiac ultrasound variables were recorded on a form designed for this purpose. The primary variables were directed at evaluating the fetal and maternal outcomes. The statistical analysis was performed using IBM-SPSS software version 23. Results: The neonatal events rate was greater than the maternal events rate (68.3% vs. 31.7%). Primary and secondary outcomes occurred in 31.7% and 12.2%, respectively. The distribution according to WHO risk category was 7.3% in risk group III, and 92.7% in group IV. There was only one maternal death unrelated to cardiovascular disease. The presence of moderate-severe tricuspid insufficiency was associated with prematurity (P=.006), and the mothers with a pulmonary systolic pressure ≥ 50 mm Hg had a greater number of newborns with respiratory distress (P=.010). Right heart failure was associated with maternal death (P=.014) and prematurity (P=.019), whilst left heart failure was associated with neonatal death (P=.003). Conclusions: Maternal cardiovascular disease is a frequent cause of high maternal-fetal morbidity and mortality. Although this study identified the main maternal and fetal outcomes, studies with a greater sample size are required.

Gait parameters in a sample of healthy Colombian adults aged between 18 and 25 years: a cross-sectional study / Parámetros de la marcha en una muestra de adultos sanos colombianos entre 18 y 25 años, un estudio transversal

Abstract Introduction: Gait analysis is fundamental for assessing the functional capacity and motor skills of any individual. Therefore, a reliable and specific analysis method is necessary to study gait in different populations. However, the reference values of gait parameters currently used in Colombia come from studies conducted on population groups from other countries or regions. Objective: To identify the reference values of gait kinematic parameters in healthy Colombian young adults. Materials and methods: A quantitative, descriptive, and cross-sectional study was conducted. The sample consisted of 155 Colombian young adults (aged 18 to 25). Temporal-spatial parameters and kinematics data of each participant were measured through 3D motion capture, which was performed using 8 infrared cameras (Bonita 10) and the VICON NEXUS 1.8.5. software. POLYGON 4.1. software was used for data analysis, and statistical analysis was performed using the STATA 12.1. software package. Results: Average age, height and BMI were 20.3 years, 1.66m and 21.91T kg/m2, respectively. 41.29% of participants were male. The average values obtained for the cadence, stride time, speed and initial swing temporal-spatial parameters were as follows: 103 steps/min, 1.16 seconds, 1.01 m/s, and 59.62% of the gait cycle (both sides), respectively. Conclusion: Normal gait kinematic and temporal-spatial parameters of a group of healthy Colombian young adults were obtained, which will allow establishing the characteristics of normal gait in this population, improving intervention strategies, and designing and implementing technical aids aimed at improving locomotion in Colombian individuals.

Class I defensins (BraDef) from broccoli (Brassica oleracea var. italica) seeds and their antimicrobial activity.

The objective of this study was to determine whether seeds of Brassica oleracea var. italica (i.e. broccoli, an edible plant) produce defensins that inhibit phytopathogenic fungi and pathogenic bacteria of clinical significance. Crude extracts obtained from broccoli seeds were fractioned by molecular exclusion techniques and analyzed by liquid chromatography-high-resolution mass spectrometry. Two peptides were identified, BraDef1 (10.68 kDa) and BraDef2 (9.9 kDa), which were categorized as Class I defensins based on (a) their primary structure, (b) the presence of four putative cysteine disulfide bridges, and (c) molecular modeling predictions. BraDef1 and BraDef2 show identities of, respectively, 98 and 71%, and 67 and 85%, with defensins from Brassica napus and Arabidopsis thaliana. BraDef (BraDef1 + BraDef2) disrupted membranes of Colletotrichum gloeosporioides and Alternaria alternata and also reduced hyphal growth of C. gloeosporioides by ~ 56% after 120 h of incubation. Pathogenic bacteria (Bacillus cereus 183, Listeria monocytogenes, Salmonella typhimurium, Pseudomonas aeruginosa, and Vibrio parahaemolitycus) were susceptible to BraDef, but probiotic bacteria such as Bifidobacterium animalis, Lactobacillus acidophilus, and Lactobacillus casei were not inhibited. To our knowledge, this is the first report of defensins present in seeds of B. oleracea var. italica (i.e. edible broccoli). Our findings suggest an applied value for BraDef1/BraDef2 in controlling phytopathogenic fungi and pathogenic bacteria of clinical significance.

Tratamiento para fractura de olécranon en pacientes mayores: Revisión sistemática / Treatment for olecranon fracture in older patients: Systematic review

Introducción El tratamiento de las fracturas de olécranon puede tener diferentes resultados, según el tipo de intervención, las características de la fractura y del paciente. Esta revisión sistemática de la literatura pretende identificar los tratamientos para el manejo de este tipo de fractura en el adulto mayor y sus resultados funcionales. Materiales y métodos Se realizó una búsqueda sistemática de la bibliografía en las bases de datos Medline, Embase y Cochrane. Se incluyeron estudios clínicos en pacientes mayores con fractura de olécranon que incluyeran resultados funcionales en sus seguimientos. Resultados De un total de 432 referencias capturadas, se incluyeron nueve estudios 6 estudios observacionales retrospectivos y 3 prospectivos. En 3 estudios se usó exclusivamente tratamiento no quirúrgico y en 4 tratamiento quirúrgico, de los cuales 2 comparan la fijación de banda de tensión con placa y 2 proponen el uso de supersuturas y suturas de anclaje. En 2 estudios comparan el tratamiento quirúrgico con el tratamiento no quirúrgico. En la evaluación de los resultados funcionales el puntaje de la Escala de Incapacidades del brazo, hombro y la mano (DASH) fue la más usada. Discusión En pacientes de edad avanzada antes de optar por fijación quirúrgica, se evalúan factores que pueden tener implicaciones en los resultados clínicos y funcionales como el número de comorbilidades y la mala calidad ósea. Este trabajo puede servir de base para la elección de tratamientos no quirúrgicos bajo condiciones requeridas, para obtener mejores resultados funcionales.

Background The treatment of olecranon fractures may lead to different outcomes, depending on the type of intervention, the characteristics of the fracture, and the patient. This systematic review of the literature aims to identify the treatments for the management of this type of fracture in the elderly and its functional results. Methods A systematic search of the bibliography was carried out in the Medline, Embase and Cochrane databases. It included clinical studies on elderly patients with olecranon fractures, as well as the functional results in their follow-up. Results Of a total of 432 references were obtained, with nine studies including 6 retrospective observational studies, and 3 prospective studies. In 3 studies, non-surgical treatment was used, and in 4 surgical treatments, 2 were comparing tension band wiring and plate fixation, and 2 proposed the use of super sutures and anchoring sutures. In 2 studies, surgical treatment was compared with non-surgical treatment. In the evaluation, the functional outcomes, the score of the Scale of disabilities of the arm, shoulder, and the hand (DASH) was the most used. Discussion In patients of advanced age, before opting for surgical fixation, factors that may have implications for clinical and functional outcomes, such as number of comorbidities and poor bone quality are evaluated. This work can serve as a basis for the choice of non-surgical treatments under the necessary conditions, and to obtain better functional results.

High yield and simple one-step production of carbon black nanoparticles from waste tires.

Carbon black (CB), a material consisting of finely divided particles, can be obtained by the partial combustion of heavy petroleum feedstock. The commercial preparation of CB nanoparticles require sophisticated equipment, chemical pre-treatment, and combination of complex separation and purification techniques. CB nanoparticles can also be recovered from scrubbed rubber, but yields are modest and the process is technically complex. Here, we report the development of a simple and inexpensive method for the preparation of CB nanoparticles from waste tires. Under optimal conditions, the yield of recovered CB nanoparticles (∼22 nm) was of approximately 81%; the nanomaterial presents good thermal stability and conductivity, and forms chain-like agglomerates; chemical composition analysis and solubility tests indicates that it is partly oxidized (C, 84.9%; S, 10.21%; O, 4.9%). The product was fully characterized by FTIR, Raman, TGA, BET, SEM and TEM. This preparation method could become a viable alternative to reduce the large amount of waste tires and decreasing their negative environmental impact, producing good quality CB nanoparticles useful for batteries, sensors, electronic devices, catalysis, pigments, concrete, and plastics, among many other applications.

Catatonia in patients with anti-NMDA receptor encephalitis.

AIM: There is a lack of studies related to the frequency, phenomenology, and associated features of catatonic syndrome in patients with anti-NMDA receptor encephalitis (ANMDARE). This study aimed to measure the frequency of catatonia in this condition and to delineate its particular symptoms. METHODS: A prospective study was done with all inpatients who fulfilled the criteria of definite ANMDARE admitted to the National Institute of Neurology and Neurosurgery of Mexico from January 2014 to September 2018. The Bush-Francis Catatonia Rating Scale and Braünig Catatonia Rating Scale were administered at admission. RESULTS: Fifty-eight patients were included and catatonia was diagnosed in 41 of these patients (70.6%). Immobility, staring, mutism, and posturing were the most frequent catatonic signs. Catatonia was associated with delirium, hallucinations, psychomotor agitation, generalized electroencephalography dysfunction, and previous use of antipsychotics. Mortality was present in 10% of the total sample; it was associated with status epilepticus, and was less frequent in the catatonia group. After immunotherapy, all cases showed a complete recovery from catatonic signs. CONCLUSION: This systematic assessment of catatonic syndrome shows that it is a frequent feature in patients with ANMDARE as part of a clinical pattern that includes delirium, psychomotor agitation, and hallucinations. The lack of recognition of this pattern may be a source of diagnostic and therapeutic errors, as most physicians associate catatonia with schizophrenia and affective disorders.

Photo-assisted electrochemical degradation of polychlorinated biphenyls with boron-doped diamond electrodes.

The capacity of the photo electro-Fenton (PEF) process to degrade a mixture of seven polychlorinated biphenyl (PCB) congeners was studied. Boron-doped diamond (BDD) sheets were used as anode and cathode in the experimental electrolytic cell that contained Na2SO4 0.05 M at pH 3 as supporting electrolyte for the electro generation of H2O2 at the cathode. The effects of UV light intensity (254 and 365 nm), current density (8, 16 and 24 mA cm-2) and ferrous ion dosage (0.1, 0.2 and 0.3 mM) on PCB (C0 = 50 µg L-1) degradation were evaluated. The highest level of PCB degradation (97%) was achieved with 16 mA cm-2 of current density, 0.1 mM of ferrous ion and UV light at 365 nm as irradiation source after 6 h of reaction. PCB28, PCB52 and PCB101 were not detected after 0.5, 1.5 and 3 h of reaction, respectively. The degradation of PCB138, PCB153, PCB180 and PCB209 was also high (>95%). The PEF system outperformed other oxidation processes (electro-Fenton, anodic oxidation, Fenton, photo-Fenton and UV photolysis) in terms of reaction rate and degradation efficiency. These results demonstrate for the first time the degradation of PCB209, the most highly chlorinated PCB congener, by an advanced electrochemical oxidation process.

Co-synthesis of kenyacin 404 and heterologous thurincin H enhances the antibacterial activity of Bacillus thuringiensis.

OBJECTIVES: To develop a recombinant strain of Bacillus thuringiensis that synthesizes two bacteriocins that enhance the antibacterial potency of the strain and that could have applied clinical and industrial value. RESULTS: We cloned the thurincin H cluster into the pHT3101 vector by assembling two genetic cassettes harboring genes for the synthesis, modification, immunity and transport of thurincin H. This construct was used to transform a thurincin H-sensitive strain of B. thuringiensis that synthesizes the kenyacin 404 to generate the recombinant Btk 404/pThurH which was immune to thurincin H and produces bacteriocins of approximately 3 kDa. A significant increase in the inhibitory activity, respectively, ~ 40 and 300%, was observed when compared with parental Btm 269 and Btk 404. Btk 404/pThurH showed increased activity against ten Gram-positive bacteria, including B. cereus, Listeria monocytogenes and B. pseudomycoides, and the Gram-negative bacterium, Sphingobacterium cabi. However, an antagonistic effect against Vibrio parahaemolyticus, relative to native strains, was observed. CONCLUSIONS: We have generated a recombinant strain of B. thuringiensis that co-synthesizes two bacteriocins (kenyacin 404, thurincin H) with improved inhibitory activity, when compared with parental strains. To our knowledge, this is the first study that shows that B. thuringiensis could be manipulated to produce two bacteriocins, one being of heterologous origin, that enhance the antibacterial activity of the recombinant strain.
