Effects of added elastic tubes on open-chain knee extensor strength training

Attaching elastic tubes (ETs) to resistance training machines can affect the exercise load profile. The purpose of this study was to assess the training effects of added ETs, which were strategically attached to provide additional loads only during the deceleration phase of the knee extension exercise. Twenty-two healthy participants, assigned to either an experimental group (with ETs) or a control group (without ETs), participated in a 12-week strength-training program using a knee extension exercise machine. The acceleration effects were quantified and a method of attaching the ETs to the knee extension machine was developed. The effects of the added ETs were analysed by testing dynamic and isometric maximum contractions at four knee flexion angles (10°, 30°, 50°, and 80°). Analyses of covariance with the initial values as the covariate were used to examine the ET effects. A greater increase in isometric maximum strength was found in the experimental group than in the control group at knee flexion angles of 10° [effect size (ES) = 2.25] and 30° (ES = 1.18). No significant difference in the dynamic maximum strength was found between the groups. The use of ETs increased strength at smaller knee flexion angles with quadriceps that were relatively short.     

Anthropometrics and electromyography as predictors for maximal voluntary isometric arm strength

BackgroundMuscular strength can be conceptually determined by two components: muscle activation and size. Muscle activation by the central nervous system can be measured by surface electromyography (sEMG). Muscular size reflects the amount of contractile protein within a skeletal muscle and can be estimated by anthropometric measurements. The purpose of this study was to determine the relative contributions of size parameters and muscle activation to the prediction of maximal voluntary isometric elbow flexion strength.MethodsA series of anthropometric measurements were taken from 96 participants. Torque and root-mean-square (RMS) of the sEMG from the biceps brachii were averaged across three maximal voluntary isometric contractions. A multiple linear regression analysis was performed based on a Pearson's correlation matrix.ResultsBody weight (BW) accounted for 39.1% and 27.3% in males and females, respectively, and was the strongest predictor of strength for males. Forearm length (L3) was the strongest predictor of strength in females (partial R² = 0.391). Elbow circumference (ELB) accounted for a significant (p < 0.05) amount of variance in males but not females. The addition of sEMG RMS as a third variable accounted for an average of 10.1% of the variance excluding the equation of BW and L3 in females. The strongest prediction equation included BW, L3, and ELB accounting for 55.6% and 58.5% of the variance in males and females, respectively.ConclusionAnthropometrics provide a strong prediction equation for the estimation of isometric elbow flexion strength. Muscle activation, as measured by sEMG activity, accounted for a significant (p < 0.05) amount of variance in most prediction equations, however, its contribution was comparable to an additional anthropometric variable.     

Institutional experience of PTH evaluation on fine-needle washing after aspiration biopsy to locate hyperfunctioning parathyroid tissue

Assaying parathyroid hormone (PTH) in the washing liquid after fine-needle aspiration biopsy (FNAB) seems to be a valid approach to locate parathyroid tissue. PTH-FNAB was evaluated in 47 patients with a clinical picture of primary hyper-parathyroidism (PHP) and ultrasonography (US) suggestive of parathyroid lesion. The patients were subdivided into two groups on the basis of the absence or presence of US thyroid alterations. The result of PTH-FNAB was compared with those of cytology, scintigraphy and, in 24 patients, surgical outcome. PTH-FNAB samples with a value higher than that recorded in the serum and higher than our institutional cut-off were deemed to be probable samples of parathyroid tissue. Cytology proved diagnostic for benign thyroid lesions, non-diagnostic for thyroid lesions, hyperplastic parathyroid tissue, undetermined or malignant thyroid lesions and other lesions in 45%, 30%, 17%, 4%, and 4% of cases, respectively. In 47% of cases, PTH-FNAB indicated that the sample had been taken in parathyroid tissue. In patients without US alterations, the diagnostic accuracy of PTH-FNAB was greater than that of scintigraphy. After surgery, comparison between the results of PTH-FNAB and scintigraphy, in terms of positive predictive value (PPV), revealed the superiority of PTH-FNAB; PPV was 94% for FNAB and 71% for scintigraphy, while sen-sitivity was 83% and 69%, respectively. PTH-FNAB evaluation after FNAB appears to be more diagnostic than cytology and scintigraphy. Of all the procedures used, PTH-FNAB appears to be the method of choice when the target is US suggestive and reachable. PTH-FNAB appears to be a useful method of guiding surgical intervention.

Teaching the Use of Library of Congress Subject Headings as a Research Strategy for Undergraduate Students

Library of Congress subject headings (LCSH) are such a powerful tool that ACRL recognized them in the Information Literacy Competency Standards. The Standards state that the information-literate student should be able to select discipline-specific controlled vocabulary and construct a search strategy. The authors, recognizing this often-forgotten Standard, surveyed instruction librarians to determine if LCSH are still taught in the library instruction classroom, and, if so, which strategies are used for identifying relevant subject headings. Survey results were mixed. While teaching the use of controlled vocabulary has clearly fallen from popularity, it is still recognized as a valuable tool.     

Croatian survey on critical results reporting

Introduction

Poor harmonization of critical results management is present in various laboratories and countries, including Croatia. We aimed to investigate procedures used in critical results reporting in Croatian medical biochemistry laboratories (MBLs).

Materials and methods

An anonymous questionnaire, consisting of 24 questions/statements, related to critical results reporting procedures, was send to managers of MBLs in Croatia. Participants were asked to declare the frequency of performing procedures and degree of agreement with statements about critical values reporting using a Likert scale. Total score and mean scores for corresponding separate statements divided according to health care setting were calculated and compared.

Results

Responses from 111 Croatian laboratories (48%) were analyzed. General practice laboratories (GPLs) more often re-analyzed the sample before reporting the critical result in comparison with the hospital laboratories (HLs) (score: 4.86 (4.75-4.96) vs. 4.49 (4.25-4.72); P = 0.001) and more often reported the critical value exclusively to the responsible physician compared to HLs (4.46 (4.29-4.64) vs. 3.76 (3.48-4.03), P < 0.001). High total score (4.69 (4.56-4.82)) was observed for selection of the critical results list issued by the Croatian Chamber of Medical Biochemistry (CCMB) indicating a high harmonization level for this aspect of critical result management. Low total scores were observed for the statements regarding data recording and documentation of critical result notification.

Conclusions

Differences in practices about critical results reporting between HLs and GPLs were found. The homogeneity of least favorable responses detected for data recording and documentation of critical results notification reflects the lack of specific national recommendations.Key words: critical results, laboratory testing, quality indicators, survey, post-analytical phase     

Enacting Social Change Along the Cultural Identity Spectrum: Intercultural Identity Construction in Faith-Based Community Organizations

This study employs Cultural Identity Spectrum Theory to analyze identity construction and positioning of faith-based nonprofit organizations (FBOs). Intercultural communication studies have not adequately analyzed religion and identity, particularly as they intersect with socio-economic class and racial marginalization. Because religion is one of the most conflict-ridden social divides, the study situates FBOs as important (inter)cultural sites, and traces an FBO's Secular–Religious location on the Cultural Identity Spectrum to critically engage cultural discourses surrounding the organization, to shift its identity to serve historically marginalized groups. Building on the dialectical approach the study interrogates challenges of creating partnerships with diverse community stakeholders to promote enduring and far-reaching social change.     

Social and educational modernisation in Spain: the work of Segell Pro Infància in Catalonia (1933–1938)

During the Second Republic of Spain (1931–1939) and within the framework of ambitious social reform, the government of the Generalitat of Catalonia launched a social and educational assistance system. This new system would be independent, modern, and capable of surpassing the traditional welfare system based on religious charity that was predominant in Spain at the time. One of the initiatives performed to obtain funding consisted of the sale of Christmas seals, whose earnings would be allocated to the fight against childhood tuberculosis. The Segell Pro Infància organisation was created for this purpose. This article analyses the origins of this institution within the socio-political context of Catalonia during the Second Republic and the Spanish Civil War, in addition to its work and activities during its brief existence. The series of actions financed by Segell were primarily directed at improving institutions that provided a social welfare system, such as crèches and nursery schools. In this analysis, the commitment of early twentieth-century Catalan nationalism to social and educational modernisation, in addition to its development of social justice policies, is revealed. This reform fits into the framework of a broader pro-sovereignty project in which Catalonia would build state structures independent of Spain.     

Ni de Aquí, Ni de Allá: Conceptualizing the self-authorship experience of gay Latino college men using conocimiento

This essay aims to enhance our conceptual understanding of students with intersectional identities, specifically gay Latino men in college. We first explain how ethnic, gender, and sexual identities can act as compounding influences. Second, we review two distinct but complementary developmental theories. Conocimiento captures the disruptive, challenging path experienced by marginalized Latino youth. Self-authorship situates the broader developmental process in and beyond college. Our modified framework—conociéndose y escribiéndose—conceptualizes how college students navigate multiple marginalized identities. Finally, we discuss the implications of this intersectional framework for LGBTQ+ students and institutions seeking to enhance diversity, inclusion, and student success.
