Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability
No full textAlthough the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its reliability. We tested the effects of increasing ABP variability, provoked by a modification of the thigh cuff method, on the ability of the autoregulation index to discriminate between normal and impaired CA, using hypercapnia as a surrogate for dynamic CA impairment. In 30 healthy volunteers, ABP (Finapres) and CBF velocity (CBFV, transcranial Doppler) were recorded at rest and during 5% CO(2) breathing, with and without pseudo-random sequence inflation and deflation of bilateral thigh cuffs. The application of thigh cuffs increased ABP and CBFV variabilities and was not associated with a distortion of the CBFV step response estimates for both normocapnic and hypercapnic conditions (P=0.59 and P=0.96, respectively). Sensitivity and specificity of CA impairment detection were improved with the thigh cuff method, with the area under the receiver-operator curve increasing from 0.746 to 0.859 (P=0.031). We conclude that the new method is a safe, efficient, and appealing alternative to currently existing assessment methods for the investigation of the status of CA

The 50 Highest Cited Papers on Rotator Cuff Tear
No full textPurpose: The purpose of this study was to determine the 50 most cited articles on rotator cuff tear and their characteristics. Methods: Thomson ISI Web of Science was searched for the following search terms “rotator cuff” and “tear.” The following characteristics were determined for each article: author(s), year of publication, source journal, geographic origin, article type (and subtype), and level of evidence for clinical articles. Results: The number of citations ranged from 1558 to 253. The 50 most often cited articles were published in 7 journals. The majority of the articles (n = 46) were clinical, with the remaining representing some type of basic science research. Among clinical articles, the case series (n = 23) was the most common article subtype. Nine articles were methodologic in that they proposed a new classification/scoring system or technique. The most common level of evidence was Level IV (n = 31). Conclusion: This article provides clinicians, researchers, and trainees with a group of articles that should be taken into consideration as building blocks in the treatment of rotator cuff tears. Level of Evidence: Level IV, literature review

ROBERT FRANCIS KENNEDY’S MORAL CRITICISMS TOWARD AMERICAN SOCIETY AND HIS SUPPORT ON MINORITY GROUPS NON-VIOLENCE ACTIONS IN 1960S
No full textYogi Rohim Aryani. C0305064. 2010. Robert Francis Kennedy’s Moral Criticisms
toward American Society and His Support on Minority Groups Non-Violence
Actions in 1960s. Thesis. English Department, Faculty of Letters and Fine Arts,
Sebelas Maret University, Surakarta.
Robert Francis Kennedy was one of the most notable figures in 1960s when
the United States of America underwent what was called as a turbulent decade
dealing with social and political problems. This research is focused on his role in
supporting minority groups non-violence actions so that their human rights could be
regained. Robert Kennedy’s support toward these groups was delivered through his
speeches and applied on his moral criticisms he held during his career as a politician
in 1952 to 1968. The thesis is aimed to find his moral criticisms that were verified
through his support toward minority groups non-violence actions in 1960s.
The source of data of the research was two speeches spoken by Robert
Kennedy in 1968. The main data were taken from the source of data that implied his
support toward social condition in the United States in time as well as toward
minority groups and their non-violence actions. The main data were then analyzed
together with supporting data taken from books, journals, articles and movie.
The thesis was a descriptive qualitative research, conducted through the
employment of library exploration. The researcher used three approaches as the
method to analyze the data and to achieve the goal of the thesis, they were:
sociopolitical approach as an approach to find out the urgency between Robert
Kennedy’s career as politician and his support toward minority groups actions in
1960s; biographical approach as an approach to comprehend the figure of Robert F.
Kennedy so that the researcher was able to discover a background of his moral
criticisms; and historical approach as an approach to reveal how social issues existed
among society in the United States shaped Robert Kennedy’s moral criticisms and
encouraged him to support Black and Latin Americans non-violence actions in
1960s.
From the research, it was found that Robert Kennedy gave his criticisms
toward three social conditions in the United States in 1960s: on the fear of difference,
on the sickness of the soul and on the use of violence. He concluded his criticisms on
the concept of society who lived under the rule of law and through his support toward
black and Latin American non-violence actions. His support was important in giving
black and Latin Americans chance to gain their basic rights as full citizen and
guaranteed their future in the country they named their own
The responsiveness and validity of the Rotator Cuff Quality of Life (RC-QOL) index in a 2-year follow-up study
No full textBackground: The Rotator Cuff Quality of Life (RC-QOL) index was developed to evaluate quality of life in patients with rotator cuff disease. This study provides additional psychometric testing in accordance with the Consensus-Based Standards for the Selection of Health Measurement Instruments guidelines. Methods: This was a 2-year follow-up study on 66 patients (mean age, 59 ± 10 years) originally presenting with chronic full-thickness rotator cuff tears to a tertiary care center. The methodology involved testing internal consistency, content validity, and criterion validity. Responsiveness was evaluated using 3 strategies: 1) standardized response mean of the raw change scores; 2) Guyatt’s Responsiveness Index; and 3) Global Rating Scales of improvement correlated to a quality of life measure. Results: Content validity was confirmed with a Cronbach a of 0.92 (95% confidence interval, 0.92-0.95) and absence of floor and ceiling effects. Criterion validity was confirmed using the Western Ontario Rotator Cuff Index as a reference standard (r ¼ 0.87, P < .001). The effect size of distribution-based methods of determining responsiveness was large (0.99-1.09) compared to that of mixed- and anchorbased methods (0.47-0.89). All responsiveness calculations met minimum requirements for acceptable thresholds. Conclusion: The RC-QOL is a valid and responsive measure of health-related quality of life in patients with chronic rotator cuff pathology. The results of this study added to the methodologic quality assessment of the RC-QOL, completarticl
Edwin F. Gay, Arch W. Shaw, and the uses of history in early graduate business education
No full textNotes that the collaboration between Edwin F. Gay, founding dean of the Harvard Graduate School of Business Administration, and Arch W. Shaw, a Chicago publisher, exemplifies the significance of historical sensibility on the origins of US management studies. Points out that the attention they gave to historical methods and data as tools of inquiry reflected Gay’s professional training in economic history, but it also reflected the sense both men had of the significance of institutions and institutional patterns in business life. Both men also urged more attention to distribution as a serious topic for academic research and teaching, and also recognized co‐ordinating activity as a central function of modern management. Adds that the potential gains from scale economies depended on how well general managers filled this function, and that for this task managers required an outlook that transcended technical expertise. Suggests that they had to understand the broader institutional setting in which they managed and that historical awareness could illuminate that context.</jats:p
Response to: The association between hypertension and rotator cuff disease: a spurious result?
No full textResponse to: The association between hypertension and rotator cuff disease: a spurious result?
Dear editor,
Thank you for giving me the opportunity to answer to letter to the Editor JSES-D-12-00464. As mentioned by the author of this letter, it is well known that the incidence of rotator cuff tears increases with age and that a large proportion of tears is completely asymptomatic4,5,6. The population prevalence of full thickness rotator cuff tears is 22.2% in females of age 60-83 years and 47% of these tears are completely asymptomatic3. The author affirms that the failure to consider the presence of asymptomatic cuff tears in the control group could fully account for the authors observation of an association between hypertension and rotator cuff tears. If we hypothetically assume that we had a plausible prevalence in the control group of asymptomatic cuff tears of 22.2%,3 it will not not affect the result that in the cuff tear patient group the prevalence of hypertension is significantly higher, but, on the contrary, it makes it more evident.
In our article, we selected 201 patients negative for shoulder pathologies because shoulder painless2 and because negative to clinical tests for cuff tears. Of course, as the author state, there is no radiological assessment of their rotator cuff.2 On the other side, a patient affected by a cuff tear (symptomatic or asymptomatic) usually does not have normal shoulder external or internal rotation strength or does have a negative external rotation lag sign.1 In addition, the main result of our study is that there is an association between size of cuff tear and hypertension and, thus, this result is not affected by eventual bias of selection of the control group, being this result calculated only in the study group (patients who underwent arthroscopic cuff repair).
Best personal regards,
Prof. Stefano Gumina (MD, PhD)
