Translation and cultural adaptation of the DSM-5 Personality Inventory – Brief Form (PID-5-BF)

Introduction: The Personality Inventory for the DSM-5 – Brief Form (PID-5-BF) – is an instrument for assessment of the five pathological personality traits from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) alternative model of personality disorders. Objectives: To determine the psychometric properties of the version of the PID-5-BF translated and adapted to Brazilian Portuguese. Methods: The process of translating and cross-culturally adapting the text was carried out by independent translators and the resulting version was administered to 176 patients in two hospitals in Rio Grande do Sul. The internal structure was tested by means of confirmatory factor analysis. Evidence of reliability was tested by examining the internal consistency of the scales and their convergent and concurrent validity with other methods of psychopathology. Results: The five factors were replicated in the present sample with adequate indicators of fit of the data to the model. Appropriate reliability coefficients for the scales and evidence of validity were observed, indicating the clinical usefulness of the PID-5-BF in the Brazilian context. Conclusion: The psychometric properties of PID-5-BF proved satisfactory in an initial sample of Brazilians

Overlap syndrome of systemic lupus erythematosus and systemic sclerosis in a person living with HIV: the paradox of immunodeficiency and autoimmunity coming together / Síndrome de overlap entre lupus eritematoso sistêmico e esclerose sístemica em pessoa vivendo com HIV: o paradoxo da imunodeficiência e autoimunidade

The existence of autoimmune dysfunction in HIV/AIDS patients is intriguing. Many cases are being reported around the world of the combination of HIV with systemic autoimmune diseases. We report a case of an HIV-infected patient that presented alopecia, symmetric polyarthritis, skin thickening and raynaud’s phenomenon. Diagnosis of overlap syndrome of SS and SLE was made and treatment with prednisone, methotrexate and nifedipine started. No HIV flare was documented

Effect of the acidified extract of Moringa oleifera leaves as a supplement in the in vitro culture medium of sheep preantral follicles

This study was conducted to evaluate the effects of the acidified extract of M. oleifera leaves as a supplement into the base medium for in vitro culture of sheep isolated secondary follicles. Follicles were isolated and cultured for 12 days in α-MEM+(supplemented with bovine serum albumin, insulin, glutamine, hypoxanthine, transferrin, selenium, and ascorbic acid) with or without 0.1; 0.2 or 0.4 mg/ml of the acidified extract of M. oleifera. Follicle morphology, antral cavity formation, follicular and oocyte diameter, glutathione (GSH) concentration, mitochondrial activity and meiotic resumption were evaluated. After 12 days of culture, there was no significant difference among treatments in relation to follicular morphology, antral cavity formation, diameter and mitochondrial activity. Nevertheless, oocytes from follicles cultured in α-MEM+ showed greater GSH concentration than media containing M. oleifera extract. Furthermore, the concentration of 0.4 mg/ml M. oleifera extract significantly increased the percentage of fully grown oocyte (≥ 110 µm) when compared to the other treatments. In conclusion, the concentration of 0.4 mg/ml M. oleifera extract as a supplement of the culture medium, maintained the survival, and increased the percentage of fully grown oocytes

Uma capitania dos novos tempos: economia, sociedade e política na São Paulo restaurada (1765-1822)

O artigo reflete sobre a trajetória da Capitania de São Paulo, a partir de 1750, apontando sua transformação, de fronteira e "boca do sertão", para território estratégico da conquista e defesa das partes meridionais e área economicamente integrada aos circuitos mercantis atlânticos.In this article, we reflect upon the history of the Captaincy of São Paulo as from 1750, drawing attention to its transformation from frontier land and "door to the backcountry" into a territory of strategic value for the purposes of conquest and defense of the southern regions, and economically integrated into the Atlantic trade routes

Cooperation between Apoptotic and Viable Metacyclics Enhances the Pathogenesis of Leishmaniasis

Mimicking mammalian apoptotic cells by exposing phosphatidylserine (PS) is a strategy used by virus and parasitic protozoa to escape host protective inflammatory responses. With Leishmania amazonensis (La), apoptotic mimicry is a prerogative of the intramacrophagic amastigote form of the parasite and is modulated by the host. Now we show that differently from what happens with amastigotes, promastigotes exposing PS are non-viable, non-infective cells, undergoing apoptotic death. As part of the normal metacyclogenic process occurring in axenic cultures and in the gut of sand fly vectors, a sub-population of metacyclic promastigotes exposes PS. Apoptotic death of the purified PS-positive (PSPOS) sub-population was confirmed by TUNEL staining and DNA laddering. Transmission electron microscopy revealed morphological alterations in PSPOS metacyclics such as DNA condensation, cytoplasm degradation and mitochondrion and kinetoplast destruction, both in in vitro cultures and in sand fly guts. TUNELPOS promastigotes were detected only in the anterior midgut to foregut boundary of infected sand flies. Interestingly, caspase inhibitors modulated parasite death and PS exposure, when added to parasite cultures in a specific time window. Efficient in vitro macrophage infections and in vivo lesions only occur when PSPOS and PS-negative (PSNEG) parasites were simultaneously added to the cell culture or inoculated in the mammalian host. The viable PSNEG promastigote was the infective form, as shown by following the fate of fluorescently labeled parasites, while the PSPOS apoptotic sub-population inhibited host macrophage inflammatory response. PS exposure and macrophage inhibition by a subpopulation of promastigotes is a different mechanism than the one previously described with amastigotes, where the entire population exposes PS. Both mechanisms co-exist and play a role in the transmission and development of the disease in case of infection by La. Since both processes confer selective advantages to the infective microorganism they justify the occurrence of apoptotic features in a unicellular pathogen

Maternal outcomes and risk factors for COVID-19 severity among pregnant women.

Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (n = 53/75)], preterm delivery [62.7% (n = 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n = 31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
