Xenobiotics Triggering Acute Intermittent Porphyria and Their Effect on Mouse Brain Respiratory Complexes.

Heme enzyme dysfunction causes a group of diseases called porphyrias. Particularly, a decrease in porphobilinogen deaminase, involved in the third step of heme biosynthesis, leads to acute intermittent porphyria (AIP). Considering our previous works demonstrating the multiplicity of brain metabolisms affected by porphyrinogenic agents, this study aimed to elucidate whether they cause any alteration on the mitochondrial respiratory chain. The activities of respiratory chain complexes (I to IV) were measured in encephalon mitochondria of CF1 male mice receiving volatile anesthetics: isoflurane (2 mL/kg) and sevoflurane (1.5 mL/kg), ethanol (30%), allylisopropylacetamide (AIA) (350 mg/kg), and barbital (167 mg/kg). Moreover, they were compared versus animals with pathological levels of 5-aminolevulinic acid (ALA, 40 mg/kg). Complex I-III activity was induced by isoflurane and decreased by AIA, ethanol, and ALA. Complex II-III activity was increased by sevoflurane and decreased by isoflurane and AIA. Complex II activity was increased by sevoflurane and barbital and decreased by AIA, ethanol, and ALA. Complex IV activity was increased by barbital and ALA and decreased by sevoflurane. The damage to the respiratory chain by ALA could be reflecting the pathophysiological condition of patients with AIP. Better understanding the broad effect of porphyrinogenic drugs and the mechanisms acting on the onset of AIP is vital in translational medicine.

Profitability determinants of the natural stone industry: Evidence from Spain and Italy.

The natural stone sector is an important driver of the Spanish and Italian economies, which underwent internationalization after the financial crisis of 2008 as part of a survival and development strategy. This article aims to study the financial and economic profitability of this sector in the two leading European production countries, as well as its determinants. For this purpose, the economic-financial data of a sample composed of 453 companies (203 Spanish and 250 Italian) from 2015-2019 were analyzed using the multiple linear regression methodology. To address the problems of possible endogeneity and omission of variables in the model, the dependent variable was used as a regressor with one and two lags, and panel data with fixed effects were considered after performing the Hausman test. The results show significant differences between the two countries, with higher profitability in Italy. Company size, company growth (measured as the change in assets), and the variation in the country's GDP all positively affected profitability. At the same time, the level of indebtedness showed a negative relationship. The country's inflation rate and gender diversity in top management were shown to be non-relevant variables. The research conducted indicates that, to increase profitability, Spanish and Italian companies in the natural stone sector should undergo mergers in order to grow in size, increase efficiency in the use of assets, reduce their dependence on external financing, and promote equity capital. In addition, Italian companies should reduce the average period of payment to suppliers to lower deferral costs, and boost exports to become less dependent on the country's domestic economy.

Obesity Contributes to Inflammation in Patients with IBS via Complement Component 3 and C-Reactive Protein.

Irritable Bowel Syndrome (IBS) is usually a lifelong state that disturbs the digestive system. IBS has been linked to low-grade inflammation and the release of inflammatory mediators into the bloodstream. This could be associated with the degree of obesity presented by patients with IBS. Reports imply that IBS is more frequent in obese patients than in the overall population, with a prevalence of up to 31%. Here, we evaluated the serum levels of immunological and inflammation molecules and their correlation with Body Mass Index in IBS patients and the healthy control (HC). Seventy-nine serum samples of the IBS patients and thirty-five of the HC group were analyzed to determine the levels of each molecule and compare them with their BMI. Serum levels of C3 and C4 were significantly increased in IBS patients. C3 and C4 levels were higher in IBS-M and IBS-D subtypes compared with the HC group. When patients were grouped by BMI, a positive correlation between serum C3 (r = 0.49, p < 0.0001) and CRP (r = 0.40, p < 0.001) levels was found. Our results show, for the first time, a correlation between immunological molecules and BMI in IBS patients, suggesting that the inflammatory nature of obesity could contribute to the development of the symptoms in IBS through the stimulation and release of proteins as complement components and CRP.

Reliability and clinical utility of the chronic pain classification in the 11th Revision of the International Classification of Diseases from a global perspective: results from India, Cuba, and New Zealand.

ABSTRACT: Chronic pain affects 1 in 5 persons and contributes substantially to the global burden of disease. The 11th Revision of the International Classification of Diseases (ICD-11) includes a comprehensive classification of chronic pain. The aim of this ecological implementation field study was to evaluate the classification's interrater reliability and clinical utility in countries with different income levels. The study was conducted in 4 pain clinics in Cuba, India, and New Zealand. Twenty-one clinicians used the ICD-11 to diagnose and code n = 353 patients with chronic pain. Of these, 111 were assessed by 2 clinicians, and Fleiss' kappa was calculated to establish interrater reliability for any diagnosis assigned to ≥15 patients. The clinicians rated the clinical utility of all diagnoses. The interrater reliability could be calculated for 11 diagnoses. It was substantial for 10 diagnoses and moderate for 1 (kappa: 0.596-0.783). The mean clinical utility of the ICD-11 chronic pain diagnoses was rated as 8.45 ± 1.69/10. Clinical utility was rated higher for ICD-11 than for the commonly used classification systems (P < 0.001, η2 = 0.25) and differed between all centers (P < 0.001, η2 = 0.60). The utility of the ICD-11 diagnoses was rated higher than the commonly used diagnoses in Dunedin and Havana, and no difference was found in Kolkata and Hyderabad. The study showed the high interrater reliability of the new chronic pain diagnoses. The perceived clinical utility of the diagnoses indicates their superiority or equality compared with the classification systems currently used in pain clinics. These results suggest the global applicability of the classification in specialized pain treatment settings.

Clinical, biochemical, and genetic characterization of acute hepatic porphyrias in a cohort of Argentine patients.

BACKGROUND: Acute Hepatic Porphyrias (AHPs) are characterized by an acute neuroabdominal syndrome including both neuropsychiatric symptoms and neurodegenerative changes. Two main hypotheses explain the pathogenesis of nervous system dysfunction: (a) the ROS generation by autooxidation of 5-aminolevulinic acid accumulated in liver and brain; (b) liver heme deficiency and in neural tissues that generate an oxidative status, a component of the neurodegenerative process. METHODS: We review results obtained from Acute Intermittent Porphyria (AIP) and Variegate Porphyria (VP) families studied at clinical, biochemical, and molecular level at the CIPYP in Argentina. The relationship between the porphyric attack and oxidative stress was also evaluated in AHP patients and controls, to identify a marker of neurological dysfunction. RESULTS: We studied 116 AIP families and 30 VP families, 609 and 132 individuals, respectively. Genotype/phenotype relation was studied. Oxidative stress parameters and plasma homocysteine levels were measured in 20 healthy volunteers, 22 AIP and 12 VP individuals. CONCLUSION: No significant difference in oxidative stress parameters and homocysteine levels between the analyzed groups were found.

Associação entre cognição, velocidade da marcha e habilitação veicular em idosos / Relación entre cognición, velocidad de la marcha y licencia de conducir en adultos mayores / Association between cognition, gait speed and vehicle habilitation in elderly people

Resumo Objetivo: Investigar a associação entre cognição, velocidade da marcha e resultado final da habilitação veicular de idosos candidatos à Carteira Nacional de Habilitação. Métodos: Estudo quantitativo de corte transversal desenvolvido em 12 clínicas de trânsito de Curitiba/Paraná/Brasil. A amostra do tipo probabilística foi constituída por 421 idosos (≥ 60 anos). Para a coleta de dados foram aplicados o Mini-Exame do Estado Mental (MEEM), teste de velocidade da marcha e realizadas consultas ao formulário Registro Nacional de Condutores Habilitados. A relação entre as variáveis foi identificada por meio do teste de regressão linear múltipla, método stepwise, utilizando-se o programa estatístico R versão 3.4.0. Resultados: Observou-se que, ao aumentar o escore no MEEM em uma unidade a chance do idoso ser considerado inapto temporariamente para dirigir diminui em 54,96% (95%; IC 28,47% - 92,69%; p<0,0001), e ao aumentar uma unidade no escore do MEEM houve um aumento na velocidade da marcha (VM) de 0,0091 (95%; IC 0,0005 - 0,0174; p=0,0366). Conclusão: O elevado escore no MEEM diminuiu a probabilidade do idoso ser considerado inapto temporariamente para dirigir veículos automotores e houve uma tendência de aumento da VM com o aumento dos escores do MEEM. A VM é um importante indicador a ser avaliado em idosos motoristas, logo, é um tópico a ser incluído nas avaliações das clínicas de trânsito, assim como o rastreamento cognitivo, fundamental para avaliar um conjunto de atividades mentais necessárias à direção veicular segura.

Resumen Objetivo: Investigar la relación entre cognición, velocidad de la marcha y obtención del permiso de conducir en adultos mayores que tramitan la licencia de conducir. Métodos: Estudio cuantitativo de corte transversal llevado a cabo en 12 centros médicos de evaluación de tránsito de Curitiba, estado de Paraná, Brasil. La muestra probabilística fue formada por 421 adultos mayores (≥ 60 años). Para la recolección de datos se aplicó el Mini Examen del Estado Mental (MEEM), la prueba de velocidad de la marcha y se realizaron consultas al formulario del Registro Nacional de Conductores Habilitados. La relación entre las variables fue identificada mediante la prueba de regresión lineal múltiple, método stepwise, con el programa de estadística R versión 3.4.0. Resultados: Se observó que, al aumentar la puntuación del MEEM una unidad, la probabilidad de que el adulto mayor sea considerado no apto temporalmente para conducir se redujo un 54,96 % (95 %; IC 28,47 % - 92,69 %; p<0,0001), y al aumentar una unidad la puntuación del MEEM, hubo un aumento en la velocidad de la marcha (VM) de 0,0091 (95 %; IC 0,0005 - 0,0174; p=0,0366). Conclusión: La puntuación del MEEM elevada redujo la probabilidad de que el adulto mayor sea considerado no apto temporalmente para conducir automóviles y hubo una tendencia de aumento de la VM con un aumento de la puntuación del MEEM. La VM es un indicador importante que debe ser evaluado en adultos mayores conductores. Por lo tanto, es un tema que deberá ser incluido en las evaluaciones de los centros médicos de evaluación de tránsito, así como también el rastreo cognitivo, fundamental para analizar un conjunto de actividades mentales necesarias para una conducción vehicular segura.

Abstract Objective: To investigate the association between cognition, gait speed and the result of vehicle habilitation of elderly candidates for the National Driver's License. Methods: Quantitative cross-sectional study developed in 12 traffic agencies in Curitiba, state of Paraná, Brazil. The probabilistic sample consisted of 421 elderly people (≥ 60 years). The Mini-Mental State Examination (MMSE), gait speed testing and consultations to forms of the National Qualified Drivers Registration were used for data collection. The relationship between variables was identified through the multiple linear regression test, stepwise method, using the statistical program R, version 3.4.0. Results: When increasing a unit in the MMSE score, the chance of the elderly person being considered as temporarily unfit to drive decreased by 54.96% (95% CI; 28.47% - 92.69%I; p<0.0001). When increasing a unit in the MMSE score, there was an increase in gait speed (GS) of 0.0091 (95% CI: 0.0005 - 0.0174; p=0.0366). Conclusion: The high MMSE score decreased the probability of the elderly participant being considered temporarily unfit to drive motor vehicles. There was a trend of higher GS with the increase in MMSE scores. As GS is an important indicator to be assessed in elderly drivers, this topic should be included in evaluations of traffic agencies, as well as cognitive screening, which is essential to assess a set of mental activities necessary for safe driving.

Asociación entre el nivel de soledad percibido y el uso de Internet en las personas sin hogar / Association between perceived loneliness and Internet use among homeless people

Resumen El objetivo de este estudio fue explorar la asociación entre los niveles de soledad percibida y el acceso a Internet en personas sin hogar. La muestra estuvo compuesta por un total de 129 personas sin hogar que asistieron a un albergue en Monterrey, México (n=129). Para medir las variables del estudio (uso de Internet y niveles de soledad de las personas sin hogar que asisten a albergues) se administró un cuestionario a cada participante, que contenía tres secciones principales: (1) datos de control; (2) uso de Internet y tecnologías de información; y (3) niveles de soledad social y emocional. Los resultados mostraron que: (1) los niveles de soledad están muy por encima del promedio reportado en estudios con otras poblaciones vulnerables; (2) el 51.9% de los participantes han usado Internet en algún momento y lo usan principalmente para contactar a familiares y amigos; y (3) existe una diferencia nominal, aunque no estadísticamente significativa, entre los niveles de soledad de los que usan Internet y los que no. Los resultados de esta investigación sugieren que proporcionar acceso a Internet en los albergues tiene potencial de impactar positivamente la calidad de vida de sus beneficiarios.

Abstract This study aimed to identify the association between the level of perceived loneliness and Internet use among homeless people. The sample consisted of 129 homeless people who were assisted at a shelter in Monterrey (Mexico). To measure the variables of the study, a survey with three main sections was conducted: demographic data, use of Internet and information technologies, and perceived levels of emotional and social loneliness. The results showed: (1) their levels of loneliness were above the average reported in studies with other vulnerable populations; (2) 51.9% of participants have used the Internet at some point in time and use it mainly to contact family and friends; (3) there is a nominal difference, although not statistically significant, between the levels of loneliness of those who use the Internet and those who do not. These results suggest that providing Internet access in shelters may positively influence the quality of life of its beneficiaries.

Partial and Transient Clinical Response to Omalizumab in IL-21-Induced Low STAT3-Phosphorylation on Hyper-IgE Syndrome.

Hyper-IgE syndrome (HIES) is a rare primary immunodeficiency characterized by elevated levels of immunoglobulin E (IgE), eczematous dermatitis, cold abscesses, and recurrent infections of the lung and skin caused by Staphylococcus aureus. The dominant form is characterized by nonimmunologic features including skeletal, connective tissue, and pulmonary abnormalities in addition to recurrent infections and eczema. Omalizumab is a humanized recombinant monoclonal antibody against IgE. Several studies reported clinical improvement with omalizumab in patients with severe atopic eczema with high serum IgE level. We present the case of a 37-year-old male with HIES and cutaneous manifestations, treated with humanized recombinant monoclonal antibodies efalizumab and omalizumab. After therapy for 4 years, we observed diminished eczema and serum IgE levels.

Introduction: Immunosuppression is one of the main obstacles in the treatment of cancer, for this reason, several natural and synthetic immunomodulators are studied, in order to attenuate the effects of conventional therapy. Objective: To evaluate the immunomodulator activity of Punica granatum Linn (pomegranade). Methods: Wistar male rats were divided into four groups: group I (control), II (immunized with red blood cells of sheep), III (immunosuppressed with cyclophosphamide and immunized with red blood cells of sheep) and IV (treated with pomegranate powder, immunosuppressed with cyclophosphamide and immunized with red blood cells of sheep). The variables studied were body weight and detection of haemagglutinating antibodies. Results: A slight tendency to increase body weight was observed in groups I, II and III, with a different response in group IV, where there was a slight decrease. The antibody titre of group III decreased with respect to II and IV, both in the primary and secondary response. In group IV the antibody titer was found to be statistically significant in relation to group III (p = 0.000) for both responses. Conclusions: Punic granatum showed immunomodulatory effect, increasing the level of haemagglutinating antibodies(AU)

Gait speed associated factors in elderly subjects undergoing exams to obtain the driver's license. / Fatores associados à velocidade da marcha em idosos submetidos aos exames para habilitação veicular.

OBJECTIVE: to analyze the factors associated with gait speed in elderly subjects undergoing physical and mental fitness tests to obtain a driver's license. METHOD: a cross-sectional quantitative study conducted in transit agencies. The probabilistic sample included 421 elderly (≥ 60 years old). The study was developed through application of questionnaires and tests that assess the frailty phenotype. For evaluating gait speed, the time spent by each participant to walk a 4.6 meter distance at normal pace on a flat surface was timed. Data were analyzed by using multiple linear regression and the stepwise method. The R statistical program version 3.4.0 was adopted. RESULTS: there was a significant association between gait speed and paid work (<0.0000), body mass index (<0.0000), Mini-Mental State Examination (=0.0366), physical frailty (pre-frail =0.0063 and non-frail <0.0000), age (<0.0000), sex (=0.0255), and manual grip strength (<0.0000). CONCLUSION: elderly drivers who do not work, women of advanced age, high body mass index, low score in the Mini-Mental State Examination, low hand grip strength, and frail tend to decrease gait speed and should be a priority of interventions.

Conclusion elderly drivers who do not work, women of advanced age, high body mass index, low score in the Mini-Mental State Examination, low hand grip strength, and frail tend to decrease gait speed and should be a priority of interventions.

Objetivo analizar los factores asociados a la velocidad de la marcha en adultos mayores sometidos a los exámenes de aptitud física y mental para habilitación vehicular. Método estudio cuantitativo de corte transversal realizado en las clínicas de tránsito, en el cual hicieron parte de la muestra del tipo probabilística 421 adultos mayores (≥ 60 años). El estudio fue desarrollado mediante aplicaciones de cuestionarios y pruebas que constituyen el fenotipo de fragilidad. Para evaluar la velocidad de la marcha fue cronometrado el tiempo gasto por el participante para andar una distancia de 4,6 metros, de manera habitual y en una superficie plana. Los datos fueron analizados utilizándose la regresión linear múltiple por medio del método stepwise. Fue adoptado el programa estadístico R versión 3.4.0. Resultados hubo una asociación significativa entre velocidad de la marcha y trabajo remunerado (<0,0000), índice de masa corporal (<0,0000), puntaje del Mini-Examen de Estado Mental (=0,0366), fragilidad física (pre-frágiles =0,0063 y no frágiles <0,0000), edad (<0,0000), sexo (=0,0255) y fuerza de prensión manual (<0,0000). Conclusión adultos mayores conductores que no trabajan, mujeres, con edad avanzada, elevado índice de masa corporal, bajo puntaje en el Mini-Examen de Estado Mental, baja fuerza de prensión manual y frágil poseen tendencia de disminución de la velocidad de la marcha y deben ser prioridad de las intervenciones.

Physical frailty and gait speed in community elderly: a systematic review. / Fragilidade física e velocidade da marcha em idosos da comunidade: uma revisão sistemática.

OBJECTIVE: To identify the outcomes of studies on gait speed and its use as a marker of physical frailty in community elderly. METHOD: Systematic review of the literature performed in the following databases: LILACS, SciELO, MEDLINE/PubMed, ScienceDirect, Scopus and ProQuest. The studies were evaluated by STROBE statement, and the PRISMA recommendations were adopted. RESULTS: There were 6,303 studies, and 49 of them met the inclusion criteria. Of the total number of studies, 91.8% described the way of measuring gait speed. Of these, 28.6% used the distance of 4.6 meters, and 34.7% adopted values below 20% as cutoff points for reduced gait speed, procedures in accordance with the frailty phenotype. Regarding the outcomes, in 30.6% of studies, there was an association between gait speed and variables of disability, frailty, sedentary lifestyle, falls, muscular weakness, diseases, body fat, cognitive impairment, mortality, stress, lower life satisfaction, lower quality of life, napping duration, and poor performance in quantitative parameters of gait in community elderly. CONCLUSION: The results reinforce the association between gait speed, physical frailty and health indicator variables in community elderly.

Effects of volatile anaesthetics on heme metabolism in a murine genetic model of Acute Intermittent Porphyria. A comparative study with other porphyrinogenic drugs.

BACKGROUND: Acute Intermittent Porphyria (AIP) is an inherited disease produced by a deficiency of Porphobilinogen deaminase (PBG-D). The aim of this work was to evaluate the effects of Isoflurane and Sevoflurane on heme metabolism in a mouse genetic model of AIP to further support our previous proposal for avoiding their use in porphyric patients. A comparative study was performed administering the porphyrinogenic drugs allylisopropylacetamide (AIA), barbital and ethanol, and also between sex and mutation using AIP (PBG-D activity 70% reduced) and T1 (PBG-D activity 50% diminished) mice. METHODS: The activities of 5-Aminolevulinic synthetase (ALA-S), PBG-D, Heme oxygenase (HO) and CYP2E1; the expression of ALA-S and the levels of 5-aminolevulinic acid (ALA) were measured in different tissues of mice treated with the drugs mentioned. RESULTS: Isoflurane increased liver, kidney and brain ALA-S activity of AIP females but only affected kidney AIP males. Sevoflurane induced ALA-S activity in kidney and brain of female AIP group. PBG-D activity was further reduced by Isoflurane in liver male T1; in AIP male mice activity remained in its low basal levels. Ethanol and barbital also caused biochemical alterations. Only AIA triggered neurological signs similar to those observed during human acute attacks in male AIP being the symptoms less pronounced in females although ALA-S induction was greater. Heme degradation was affected. DISCUSSION: Biochemical alterations caused by the porphyrinogenic drugs assayed were different in male and female mice and also between T1 and AIP being more affected the females of AIP group. GENERAL SIGNIFICANCE: This is the first study using volatile anaesthetics in an AIP genetic model confirming Isoflurane and Sevoflurane porphyrinogenicity.
