The retear rate after rotator cuff repair remains unacceptably high. Various biological engineered scaffolds have been proposed to reduce the retear rate. We have developed a double rip-stop repair with medial row knot (DRSK) technique to enhance suture-tendon strength and a novel engineered tendon-fibrocartilage-bone composite (TFBC) for rotator cuff repair.

DRSK rotator cuff repair augmented with TFBC will have better biomechanical properties than that of DRSK repair with an acellular dermal graft (DG).

Controlled laboratory study.

Fresh-frozen canine shoulders (n = 30) and knees (n = 10) were used. TFBCs were harvested from the patellar tendon-tibia complex and prepared for rotator cuff repair. The infraspinatus tendon was sharply detached from its bony attachment and randomly assigned to the (1) control group DRSK repair alone, (2) TFBC group DRSK repair with TFBC, and (3) DG group DRSK repair with DG. All specimens were tested to failure, and videos were recorded. The footprint area, tendon thickK technique.

TFBC may help to reduce retear or gap formation after rotator cuff repair using the DRSK technique.[This corrects the article on p. 139 in vol. 9, PMID 32766324.].Clinical informationist (CI) is one of the current trends in the field of medical librarianship and information science. CIs are members of clinical care teams, and their main duty is to fill the gap in the information needs of health-care workers and patients using information sources. They need an official and standard education. This study aims to identify the educational goals and needs of CIs. To this end, a scoping review was conducted using the Preferred Reporting Item for Systematic Reviews and Meta-analyses guidelines. The ISI Web of Science, Scopus, Proquest (MEDLINE), Science Direct, Emerald, ERIC, Cochrane, and Library, Information Science and Technology Abstracts were searched. The Journal of the European Association for Health Information and Libraries was hand searched for relevant studies. A total of 1026 studies were extracted, and 38 studies were selected for the final review. The review resulted in identifying 18 goals in cognitive, emotional, and psychomotor areas. Furthermore, the educational needs were identified in eight educational needs including research method and statistics, education, medical knowledge, information and librarianship science, clinical environment knowledge, evidence-based knowledge, information technologies and systems, management, and leadership. Although part of these educational needs can be met through general medical librarianship and information science education, further specialized education for CIs requires specific aims and curriculum. Thus, the results of this study can be the basis for future studies regarding the competencies of CI in order to provide a more precise and detailed curriculum based on these educational needs.

In chronic diseases such as osteoporosis, understanding the factors that improve prevention, such as health literacy (HL), is essential in reducing the incidence of these diseases. This study aimed to determine the association between HL and adoption of osteoporosis-preventive behaviors among students in Qazvin.

This is a cross-sectional study in which 375 female students (aged 15-18 years) at high schools (grades 10

, 11

, and 12

) in Qazvin city were selected, in 2019. Sampling method was multistage. To collect data, the standardized questionnaire for measuring HL in adolescents (health literacy measure in adolescents), in addition to another questionnaire for assessing osteoporosis-preventive behaviors, was used. Data were analyzed using SPSS 22 by descriptive statistics and logistic regression. The association considered significant when

< 0.05.

The mean scores of adoption of osteoporosis-preventive behaviors and HL were 22.43 ± 5.60 and 70.84 ± 12.58, respectively. Logistic regression showed that there was a significant association between the adoption of osteoporosis-preventive behaviors and HL (

= 0.001). In addition, the association between the adoption of osteoporosis-preventive behaviors and age was also significant (

= 0.048 and odds ratio = 3.35).

Young students and those of low HL showed less adoption of osteoporosis-preventive behaviors. Therefore, it is necessary to pay more attention to design educational programs that may raise the knowledge and awareness of those students about such these diseases, mainly prevention.

Anticipating the increased need of telemedicine by health-care providers, the Medical Council of India released practice guidelines in March 2020. In this article, the literature pertinent to telemedicine and its applications with special reference to recently released practice guidelines were reviewed and summarized in a historical and current context. Telemedicine is bound to grow and be adopted by more health-care practitioners and patients in a wide variety of forms due to ease and availability. At the same time, it cannot replace in-person consultation or emergency medicine.

Occupational accidents have many undesirable and irreparable effects on labor forces, assets, environment, and credibility of organizations. Human errors are one of the most important causes of occupational accidents. Human errors have different causes, but in all cases, human cognitive abilities and limitations play important roles; in this research, the relationship between occupational cognitive failures and work-related accidents in heavy equipment operators of Shahid Rajaee Port Complex has been investigated.

This research was done through the field method. A sample of 332 people was selected by a stratified sampling method among all heavy equipment operators. The data gathering tool contained a 30-item occupational cognitive failure questionnaire. Furthermore, regression analysis method was used to test the hypotheses.

The results of this study showed that cognitive failures of occupational accidents on direct work-related accidents in heavy equipment operators of Shahid Rajaee Port complex have a direct effect (
