Background: The lateral ankle ligament complex is the most frequently injured ligament secondary to strong ankle inversion movement during lateral ankle sprains (LAS). Among these injuries, anterior talofibular ligament (ATFL) injury is the most frequent condition (present in 66–85% of such injuries). The purpose of this research was to use magnetic resonance imaging (MRI) to determine the association between ankle tendon, ligament, and joint conditions and ATFL injuries. Methods: A case-control MRI study was carried out to compare the presence of ankle muscle, tendon, ligament, and joint conditions in patients with injured ATFLs (case group; n=25) and non-injured ATFLs (control group; n=25). Results: Achilles tendinopathy was present in 1/25 (4%) patients with injured ATFLs and 7/25 (28%) non-injured ATFL subjects (P=0.048). Injured calcaneofibular ligaments (CFLs) were present in 19/25 (76%) patients with injured ATFLs and 1/25 (4%) non-injured ATFL subjects (P<0.001). Finally, injured tibiotalar joints were present in 16/25 (64%) patients with injured ATFLs and 5/25 (20%) non-injured ATFL subjects (P=0.002). Other musculoskeletal structure injuries occurred at similar rates between patients with injured ATFLs and those with non-injured ATLFs (P≥0.05). Conclusions: Patients with ATFL injuries showed a greater presence of CFL and tibiotalar joint injuries than subjects with non-injured ATFLs.

Objective: To compare central sensitization symptoms, presence of central sensitivity syndrome (CSS), catastrophism, rumination, magnification, and helplessness symptoms between athletes with gastrocnemius myofascial pain and healthy athletes. Furthermore, to predict central sensitization symptoms based on sociodemographic and descriptive data, catastrophism features, and presence of gastrocnemius myofascial pain in athletes.Design: Case–control study.Setting: Outpatient clinic.Subjects: Fifty matched paired athletes were recruited and divided into patients with chronic (more than three months) gastrocnemius myofascial pain (N = 25) and healthy subjects (N = 25).Methods: Central sensitization symptoms and CSS presence (≥40 points) were determined by the Central Sensitization Questionnaire (CSQ). Catastrophism symptoms and rumination, magnification, and helplessness domains were measured by the Pain Catastrophizing Scale (PCS). Statistical significance was set at P < 0.01 for a 99% confidence interval.Results: Statistically significant differences (P ≤ 0.001) with a large effect size (d = 1.05–1.19) were shown for higher CSQ scores and PCS total and domain scores in athletes with gastrocnemius myofascial pain vs healthy athletes. Nevertheless, CSS presence (CSQ ≥ 40 points) did not show statistically significant differences (P = 0.050) between groups. A linear regression model (R2 = 0.560, P < 0.01) predicted higher CSQ scores based on PCS total score (R2 = 0.390), female sex (R2 = 0.095), and myofascial pain presence (R2 = 0.075).Conclusions: Greater symptoms of central sensitization, catastrophism, rumination, magnification, and helplessness were shown in athletes with gastrocnemius myofascial pain compared with healthy athletes. Nevertheless, there was not a statistically significant presence of CSS comparing both groups. Greater central sensitization symptoms were predicted by catastrophism symptoms, female sex, and presence of gastrocnemius myofascial pain in athletes.

Background: Primary dysmenorrhea (PD) is one of the most common gynecological disorders in women of reproductive age that may affect quality of life. It is believed that the underlying cause of PD may be the excessive production of prostaglandins (PGs), however, between 20%–25% of women with PD did not respond to pharmacological treatments, showing that nociceptive mechanisms underlying PD are still not understood. The purpose of this study was to measure and compare, through the use of ultrasound imaging, the thickness at rest of the abdominal wall, as well as the interrecti distance (IRD), in women with and without PD. Methods: A cross-sectional study has been performed using ultrasound imaging (USI) to measure the resting thickness of the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), rectus abdominis (RA), as well as the IRD in a sample of 39 women, 19 with PD and 20 without PD (median ± IR age: 20 ± 4 and 22.5 ± 7 years, respectively). Results: Findings of muscular thickness did not reveal statically significant differences (p < 0.05) in EO, IO, TrAb, RA, and the IRD between the PD group and control group. Conclusions: These findings suggest that the thickness of the abdominal wall is not associated with PD.

Tailor’s bunion (TB) disease should be considered one of the foot injuries that causes disability in feet as well as general health. This case–control descriptive study investigated and contrasted the effects of different TB types in a sociodemographic population using the Foot Health Status Questionnaire (FHSQ). A sample of 100 subjects with a mean age of 51.70 ± 17.78 years was recruited and requested to reply to a foot health survey. Results were self-reported. Subjects were scored. Participants with TB type III (TB3) registered lower scores for foot pain, foot function, footwear, and foot health. Physical activity and social capacity had higher scores, and vigor and general health were lower. A Kruskal–Wallis test was used for systematic differences between the FHSQ and different TB types. In all analyses, statistical significance was considered a p-value <0.05 with a 95% confidence interval. Statistically significant differences were found between all domains of the FHSQ and TB, except for the social capacity domain and vigor. The FHSQ is an important measurement tool in TB subjects, showing that factors such as sex, age, and footwear used throughout an individual’s life are significantly associated with the development of TB3 and its influence on foot pain and foot health.

The coronavirus 2019 (COVID-19) pandemic has prompted several changes in the learning methods of students. The purpose of this study was to establish whether a relationship between levels of resilience, self-esteem, anxiety, depression, and academic stress in both hybrid and virtual learning education exist. A descriptive and observational case-control study was carried out in universities that offer nursing designation. A total sample of 140 freshman nursing students was recruited. Concretely, 70 participants were recruited from an university receiving hybrid education and 70 participants were recruited from another university receiving virtual learning education. Nursing students self-reported the following questionnaires: the Rosenberg Self-Esteem scale, the 10 CD-Risk Connor-Davidson Risk Resilience Scale, the Beck Anxiety Inventory, the Beck Depression Inventory and the Academic Stress Coping Scale. Significant differences (P = 0.001) showed higher depression levels for students who received virtual education versus received hybrid education. Differences in Rosenberg test for self-esteem and Beck Anxiety Inventory for anxiety (P > 0.05) were not found. Students who received online education presented higher depression levels which could be due to they had not face-to-face relationships with teachers or classmates, whereas the hybrid education group received a different type of direct interaction with teachers and peers.
