Histologic evaluation of bone healing of adjacent alveolar sockets grafted with bovine- and porcine-derived bone: a comparative case report in humans

To evaluate and compare histomorphometrically the bone response to two xenografts, one bovine and the other porcine, grafted in adjacent extraction sockets in a human. In this case report, two adjacent maxillary premolars were extracted, and the sockets were filled with two different xenogeneic bone substitutes (first premolar with bovine bone, and second premolar with porcine bone) to counteract post-extraction volume loss. Following 6 months bone core specimens were harvested during the placement of implants at the regenerated sites. Histomorphometrically, for the bovine xenograft the percentage of newly formed bone (osteoid) was 26.85%, the percentage of the residual graft material was 17.2% and the percentage of connective tissue 48.73%, while for the porcine xenograft, newly formed bone (osteoid) represented 32.19%, residual graft material was 6.57% and non-mineralized connective tissue was 52.99%. Histological results indicated that both biomaterials assessed in this study as grafts for socket preservation technique are biocompatible and osteoconductive. Bovine bone derived demonstrated to be less resorbable than porcine bone derived. Both xenogenic biomaterials did not interfere with the normal bone reparative processe

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

Eduardo e il mondo del cinema

Il saggio si occupa delle opere cinematografiche di uno degli autori e attori più importanti del teatro del Novecento. Nella considerazione generale, l’attività nel mondo del cinema è stata giudicata, dalla critica si settore e dal mondo della cultura, assai meno significativa di quella della scena drammatica. In realtà, ad una analisi più attenta e riflessiva, si può agevolmente constatare che Eduardo, attivo nel cinema dall’inizio degli anni trenta agli anni sessanta, raggiunse risultati importanti e significativi anche nello schermo, sia come di attore, sia come sceneggiatore e perfino regista di alcune sue realizzazioni. Naturalmente un discorso a parte, ma ugualmente “rivalutativo”, merita la sua lunga partecipazione alle realizzazioni televisive che videro la trasposizione in video di gran parte del suo repertorio teatrale

Visual Encounters in "Lost and Delirious" and "Blue is the Warmest Color"

The essay focuses on the surge of homosexual desire in adolescent girls as dealt with 'Lost and Delirious' (2001), a film of Léa Pool, and 'Blue is the Warmest Color' (2010), a graphic novel by young French artist Julie Maroh, adapted by French-Tunisian Director Adbellatif Kechiche as 'La Vie d'Adèle' (2013). The methodology of visual culture is to describe the tensions between visual and verbal representation

Validação de material informativo a pacientes em tratamento quimioterápico e aos seus familiares Validación del material informativo a los pacientes en tratamiento de quimioterapia y a sus familiares Validation of the informative material for patients and their families undergoing chemotherapeutical treatment

O objetivo deste estudo foi a validação do conteúdo e a compreensibilidade do Material informativo a pacientes em tratamento quimioterápico e aos seus familiares. Para avaliar se as informações do material informativo sobre câncer, quimioterapia, cuidados com paciente, alimentação e medicação eram suficientemente esclarecedoras e claras, foram contatados 23 cuidadores principais de crianças com câncer. Os entrevistados responderam a um questionário contendo nove questões fechadas e uma aberta. A avaliação foi positiva e as informações foram consideradas esclarecedoras pela maioria dos participantes, dos quais alguns contribuíram com sugestões, que foram acrescentadas ao material. Após completa finalização, o material servirá como apoio aos pacientes com câncer e aos familiares. O intuito do material é melhorar a qualidade de assistência de enfermagem, pois acredita-se que, quando os responsáveis estão orientados sobre a maneira mais adequada de cuidar, a adesão do paciente ao tratamento aumenta, a informação os torna mais seguros, e colabora-se para o sucesso do tratamento.<br>Refiérase a la validación del contenido y a la comprensibilidad del material informativo a los pacientes en tratamiento de quimioterapia y a sus familiares.

La evaluación fue positiva y las informaciones fueron consideradas satisfactorias y esclarecedoras para la mayoría de las personas. Algunas hicieron sugerencias que fueron incluidas en el material. El material informativo pretende ser implantada con el objetivo de mejorar la cualidad de la asistencia de enfermería, pues se cre que cuando los responsables estan orientados sobre la manera más adecuada de cuidar, mejora la adesión al tratamiento, la información los deja más seguros y colabora para el suceso del tratamiento.<br>The objective of this study was to validate the content and comprehensibility of the informative material for patients and their families undergoing chemotherapy, while describing its utility as a written tool of communication between healthcare provider and healthcare consumers. The informative material draws on information derived from twenty-three interviews of caretakers. The data were collected via surveys involving nine closed questions plus one open-ended question to analyze if the material's content was self-explanatory, sufficient and clear. The analyses of the informative material was positive and the information within was considered satisfactory and explanatory to the majority of the interviewees. Some of the people interviewed contributed with suggestions, which were added to the material. The informative material will be introduced, aimed at improving the quality of nursing assistance provided to cancer patients, as it is believed that when health professionals are well oriented regarding the most adequate way to care, patients adhere to their treatment more seriously; in other words, the information makes them feel more secure and fosters collaboration, leading to successful treatment
