Mycobacterium tuberculosis expressing phospholipase C subverts PGE2 synthesis and induces necrosis in alveolar macrophages
Abstract\ud
\ud
Background\ud
Phospholipases C (PLCs) are virulence factors found in several bacteria. In Mycobacterium tuberculosis (Mtb) they exhibit cytotoxic effects on macrophages, but the mechanisms involved in PLC-induced cell death are not fully understood. It has been reported that induction of cell necrosis by virulent Mtb is coordinated by subversion of PGE2, an essential factor in cell membrane protection.\ud
\ud
\ud
Results\ud
Using two Mtb clinical isolates carrying genetic variations in PLC genes, we show that the isolate 97-1505, which bears plcA and plcB genes, is more resistant to alveolar macrophage microbicidal activity than the isolate 97-1200, which has all PLC genes deleted. The isolate 97-1505 also induced higher rates of alveolar macrophage necrosis, and likewise inhibited COX-2 expression and PGE2 production. To address the direct effect of mycobacterial PLC on cell necrosis and PGE2 inhibition, both isolates were treated with PLC inhibitors prior to macrophage infection. Interestingly, inhibition of PLCs affected the ability of the isolate 97-1505 to induce necrosis, leading to cell death rates similar to those induced by the isolate 97-1200. Finally, PGE2 production by Mtb 97-1505-infected macrophages was restored to levels similar to those produced by 97-1200-infected cells.\ud

Choral singing therapy following stroke or Parkinsons disease: An exploration of participants experiences
© 2015 Informa UK Ltd. Purpose: People with stroke or Parkinsons disease (PD) live with reduced mood, social participation and quality of life (QOL). Communication difficulties affect 90% of people with PD (dysarthria) and over 33% of people with stroke (aphasia). These consequences are disabling in many ways. However, as singing is typically still possible, its therapeutic use is of increasing interest. This article explores the experiences of and factors influencing participation in choral singing therapy (CST) by people with stroke or PD and their significant others. Method: Participants (eight people with stroke, six with PD) were recruited from a community music therapy choir running CST. Significant others (seven for stroke, two for PD) were also recruited. Supported communication methods were used as needed to undertake semi-structured interviews (total N = 23). Results: Thematic analysis indicated participants had many unmet needs associated with their condition, which motivated them to explore self-management options. CST participation was described as an enjoyable social activity, and participation was perceived as improving mood, language, breathing and voice. Conclusions: Choral singing was perceived by people with stroke and PD to help them self-manage some of the consequences of their condition, including social isolation, low mood and communication difficulties.Implications for RehabilitationChoral singing therapy (CST) is sought out by people with stroke and PD to help self-manage symptoms of their condition.Participation is perceived as an enjoyable activity which improves mood, voice and language symptoms.CST may enable access to specialist music therapy and speech language therapy protocols within community frameworks

Mycobacterium tuberculosis complex differentiation using gyrB-restriction fragment length polymorphism analysis
Mycobacterium tuberculosis complex (MTBC) members are causative agents of human and animal tuberculosis. Differentiation of MTBC members is required for appropriate treatment of individual patients and for epidemiological purposes. Strains from six MTBC species - M. tuberculosis, M. bovis subsp. bovis, M. bovis BCG, M. africanum, M. pinnipedii, and "M. canetti" - were studied using gyrB-restriction fragment length polymorphism (gyrB-RFLP) analysis. A table was elaborated, based on observed restriction patterns and published gyrB sequences. To evaluate applicability of gyrB-RFLP at Instituto Adolfo Lutz, SĂŁo Paulo, Mycobacterial Reference Laboratory, 311 MTBC clinical isolates, previously identified using traditional methods as M. tuberculosis (306), M. bovis (3), and M. bovis BCG (2), were analyzed by gyrB-RFLP. All isolates were correctly identified by the molecular method, but no distinction between M. bovis and M. bovis BCG was obtained. Differentiation of M. tuberculosis and M. bovis is of utmost importance, because they require different treatment schedules. In conclusion, gyrB-RFLP is accurate and easy-to-perform, with potential to reduce time needed for conventional differentiation methods. However, application for epidemiological studies remains limited, because it cannot differentiate M. tuberculosis from M. africanum subtype II, and "M. canetti", M. africanum subtype I from M. pinnipedii, and. M. bovis from M. bovis BCG
O cargo pĂșblico de livre provimento na organização da administração pĂșblica federal brasileira: uma introdução ao estudo da organização da direção pĂșblica na perspectiva de estudos organizacionais Public position filled by appointment in the Brazilian federal administration: an introduction to the study of public management organization from the organizational studies perspective
A organização da administração pĂșblica federal brasileira Ă© raramente abordada na pesquisa no campo de estudos organizacionais (EOs). Privilegia-se a tomada de decisĂŁo, seguindo-se a tradição de pesquisa operacional de cunho funcionalista. Contudo, direção Ă© mais complexa e inclui decisĂŁo. A direção na administração pĂșblica federal brasileira se dĂĄ exclusivamente por meio de cargos de livre provimento. Tal realidade permite entender a direção como ação eminentemente polĂtica, cristalizada na organização da administração pĂșblica. Este artigo possui carĂĄter metodolĂłgico e demonstra que o cargo pĂșblico de livre provimento possui centralidade na organização da administração pĂșblica federal brasileira. Identifica, ainda, prĂĄticas de operação e interaçÔes no exercĂcio da direção pĂșblica.<br>The organization of the Brazilian federal public administration is seldom addressed by organizational studies (OS) research. The decision-making process is privileged, according to the tradition of functionalist operational research. However, managing is more complex than decision-making, which is included by it. Management level in Brazilian federal public administration is completely filled by appointment. This reality makes us understand management as an utterly political action, crystallized in the public administration organization. This article has a methodological perspective and demonstrates that public positions filled by appointment are central to the Brazilian federal public administration,. It also identifies practices and interactions of public management

30-Day morbidity and mortality of bariatric metabolic surgery in adolescence during the COVID-19 pandemic â The GENEVA study
Background: Metabolic and bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity. Objectives: This study examined the safety of MBS in adolescents during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This was a global, multicentre and observational cohort study of MBS performed between May 01, 2020, and October 10,2020, in 68 centres from 24 countries. Data collection included in-hospital and 30-day COVID-19 and surgery-specific morbidity/mortality. Results: One hundred and seventy adolescent patients (mean age: 17.75 ± 1.30 years), mostly females (n = 122, 71.8%), underwent MBS during the study period. The mean pre-operative weight and body mass index were 122.16 ± 15.92 kg and 43.7 ± 7.11 kg/m2, respectively. Although majority of patients had pre-operative testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n = 146; 85.9%), only 42.4% (n = 72) of the patients were asked to self-isolate pre-operatively. Two patients developed symptomatic SARS-CoV-2 infection post-operatively (1.2%). The overall complication rate was 5.3% (n = 9). There was no mortality in this cohort. Conclusions: MBS in adolescents with obesity is safe during the COVID-19 pandemic when performed within the context of local precautionary procedures (such as pre-operative testing). The 30-day morbidity rates were similar to those reported pre-pandemic. These data will help facilitate the safe re-introduction of MBS services for this group of patients
