(Wiley, 2024-10-08) Mayagoitia-Vázquez, José de Jesús; López-López, Daniel; Miguel-Andrés, Israel; Becerro-de-Bengoa-Vallejo, Ricardo; Losa-Iglesias, Marta; Gómez-Salgado, Juan; Ortiz-Lango, Luis Ángel
The claw toe deformity is a painful condition that mainly affects the adult population. Although there are many different treatments to solve the deformity, there is no optimal procedure to restore the normal foot mechanics. The objective of this review was to identify the technical features of the kinematic evaluation methods used in patients with claw toes. Furthermore, the aim of this review was to clarify what is known and what is needed apart from the surgical procedures to correct the claw toe deformity, with the purpose of reducing risk factors of falling in elderly people. A search in electronic databases, such as Scopus (n = 78), Google Scholar (n = 705) and ScienceDirect (n = 290) was conducted. There were seven articles (43.75%) related to the fixation (arthrodesis) of proximal and distal interphalangeal joints, one article (6.25%) describes the correction of the claw toe through plantar plate tenodesis and release of collateral ligaments, four articles (25%) describe the procedure of tendon transfer, one article (6.25%) describes flexor digitorum brevis tenotomy and a proximal interphalangeal joint arthrolysis, and another article (6.25%) presented the impact of partial phalanx osteotomy to treat the claw toe deformity. In conclusion, the review indicates that there are several studies related to the treatment or correction of claw toe deformity. However, there is a lack of knowledge of the postsurgical effects of treating claw toe condition, especially in the structural mechanics (plantar pressure distribution, stability, gait, foot mechanics and so on) of the foot after the correction of the claw toe deformity. The analysis of the foot mechanics after the correction of the claw toes has to be paramount to determine the benefits of the correction. Keywords: claw toes; foot; gait; lesser toes deformities.
Alcohol-Based Chlorhexidine and Potassium Sorbate Rub Strengthens the Effectiveness of Traditional Hand Scrubbing and Improves Long-Lasting Effectiveness-Evaluation of Hand Preparation Protocols According to EN 12791
(MDPI, 2024-05-20) Alou, Luis; Martin-Villa, Carlos; Becerro-de-Bengoa-Vallejo, Ricardo; Losa-Iglesias, Marta; Sevillano, David
Despite the advantages of surgical handrub in terms of the ease of application and effectiveness, chlorhexidine (CHG)-based hand scrubbing remains the preferred method for surgical hand preparation. However, it does not systematically meet the non-inferiority requirement of the European norm (EN) 12791 with respect to n-propanol (the reference product) and does not provide the sustained efficacy expected for these long-lasting agents. Commercially available alcohol-based products have also failed to demonstrate sustained efficacy according to EN 12791. Multi-step protocols enhance the efficacy of hand scrubbing, yet their extended disinfection duration might diminish their allure for healthcare professionals. In this study, we show that hand scrubbing with CHG 4% followed by a 1 min rubbing with the novel formulation of ethanol (Et) 70%/CHG 3% plus 0.3% potassium sorbate food additive (PS) meets the non-inferiority requirement and demonstrates sustained efficacy when tested according to EN 12791. The immediate and 3 h effect of this protocol was significantly higher than that of n-propanol and the homologous disinfection protocol without PS (CHG 4% hand scrub plus Et 70%/CHG 3% rub), demonstrating that the inclusion of PS confers a notable residual effect. We speculate that this non-volatile ingredient acts synergistically with CHG. This promising combination represents an alternative method for the development of new disinfection strategies. Keywords: EN 12791; chlorhexidine; ethanol; potassium sorbate; surgical hand preparation.
An overview of the risk factors for producing fifth metatarsal fracture in sports activities: A systematic review
(2024) Ortiz-Lango, Luis Angel; Miguel-Andrés, Israel; López-López, Daniel; Mayagoitiza-Vázquez, José de Jesús; Becerro-de-Bengoa-Vallejo, Ricardo; Losa-Iglesias, Marta; Gómez-Salgado, Juan; Saavedra-García, Miguel Ángel
Introduction: The fifth metatarsal fracture is a foot injury that occurs in sports activities. This fracture has been associated with risk factors based on intrinsic variables such as type of feet (flatfoot or cavus foot), foot pathologies, and bone density among others. Extrinsic variables associated with fifth metatarsal fractures include sports maneuvers, the type of sports practice, and contact surface. Although this injury has been investigated over the years, there is no consensus on the most relevant risk factors that cause this injury. An increase in the number of people with fractures makes it a relevant topic of research. The objective of this review was to identify an overview of the risk factors for producing the fifth metatarsal fracture based on intrinsic and extrinsic variables in sports activities. Furthermore, this review aimed to clarify what is known and what is needed on the risk factors that can influence the appearance of the fracture. Methods: A search in electronic databases, such as Scopus (n = 87), PubMed (n = 187), and Web of Science (n = 173) was conducted. The initial search yielded 447 titles and abstracts, from which 31 papers were selected for detailed analysis after screening all citations against the eligibility criteria. Results: After screening the manuscripts, it was found that the fifth metatarsal fracture can be produced by multiple factors. However, most of the studies focus on one or two specific risk factors. It was found that soccer (38.7%) is the sports activity that presents a higher risk of getting a fifth metatarsal fracture compared to other sports activities. The second risk factor was the performance of critical maneuvers (22.5%) and the third one was the biomechanics of the foot (22.5%). Conclusion: It is paramount to identify the most critical risk factors linked to the fifth metatarsal fracture to be able to implement effective treatments and prevention strategies. Keywords: fifth metatarsal fracture; foot; risk factors; sport.

(Wiley, 2022) Jiménez-Fernández, Raquel; Corral-Liria, Inmaculada; Trevissón-Redondo, Bibiana; Lopez-Lopez, Daniel; Losa-Iglesias, Marta; Becerro-de-Bengoa-Vallejo, Ricardo
BackgroundIn April 2020, Spain was the country with the highest number of patients infected by COVID-19 in Europe. The pressure on health care providers has had a direct impact on nurses and their mental health.AimThe aim of this study is to demonstrate the causal relationship between resilience, acceptance, experiential avoidance, psychological inflexibility and burnout syndrome, all of which are measured with validated questionnaires.MethodsThis was designed as a transversal correlational study with nurses who worked during the acute phase of the pandemic in public hospitals in the Community of Madrid with patients diagnosed with COVID-19 in COVID-19 medical hospitalization units, emergency services and intensive care units. Google Forms was used to obtain an informed consent sheet, socio-demographic variables and the following questionnaires: 10 CD-Risk, Connor-Davidson Risk Resilience Scale, Acceptance and Action Questionnaire-II and the Maslach Burnout Inventory.ResultsThe final sample included 375 nurses with a high number of consecutive days of direct exposure to an infected patient and a very high number of consecutive days without rest; almost 18% suffered from COVID-19. The nurses presented medium levels of resilience, medium levels of experiential avoidance and medium levels as measured for emotional exhaustion, personal accomplishment and depersonalization. We also found a predictive correlation between all the dimensions of the burnout questionnaire in relation to the data obtained from the resilience questionnaire.ConclusionsThere is a direct and predictive relationship between the resilience that nurses had during the acute phase of the pandemic and their capacity for acceptance, experiential avoidance, psychological inflexibility and burnout syndrome.Implications for Nursing ManagementThe scores show the necessity to implement preventive measures to avoid fatal psychological consequences for nurses.

(Healthcare (Basel), 2021) Casado-Hernández, Israel; Becerro-de-Bengoa-Vallejo, Ricardo; Losa-Iglesias, Marta; Cosín-Matamoros, Julia; Calvo-Lobo, César; Rodríguez-San, David; López-López, Dabiel; Martínez-Jímenez, Eva María
Harderness insoles decrease plantar pressure and reduce the foot injury incidence in sport. The purpose of our study was to analyze the plantar pressure variation in moto riders after riding in a real speed circuit with a custom foot 52 degrees Shore EVA insole. Methods: A crossover randomized trial study was performed (consent no. #050520165316). Riders were assessed by an expert motorsport senior podiatry. The participants' mean age was 35 +/- 3.29. Participants completed a 20 min training riding with their own motorcycle in a real speed circuit. Plantar pressures were registered with a baropodometric platform evaluating an Ethyl Vinyl Acetate custom foot insole (CFI) manufactured with 3 mm thickness and 52 degrees Shore A hardness. The Plantar pressures were registered before riding, after riding without EVA insole, and after riding with EVA insole. Results: Total Plantar pressures in right and left foot, and total surface area decrease after riding with EVA insoles. Conclusion: The use of an EVA insole with 52 degrees shore A hardness riding on a motorcycle in speed circuit decreased the total plantar pressures and surface areas values.
Influence of the biomechanical evaluation of rupture using two shapes of same intramedullary implant after proximal interphalangeal joint arthrodesis to correct the claw/hammer pathology: A finite element study
(2024) Bayod-López, Javier; Becerro-de-Bengoa-Vallejo, Ricardo; Prados-Frutos, Juan Carlos; Losa-Iglesias, Marta; López-López, Daniel; Prados-Privado, María
We used finite element analysis to study the mechanical stress distribution of a new intramedullary implant used for proximal interphalangeal joint (PIPJ) arthrodesis (PIPJA) to surgically correct the claw-hammer toe deformity that affects 20% of the population. After geometric reconstruction of the foot skeleton from claw toe images of a 36-year-old male patient, two implants were positioned, in the virtual model, one neutral implant (NI) and another one 10° angled (10°AI) within the PIPJ of the second through fourth HT during the toe-off phase of gait and results were compared to those derived for the non-surgical foot (NSF). A PIPJA was performed on the second toe using a NI reduced tensile stress at the proximal phalanx (PP) (45.83 MPa) compared to the NSF (59.44 MPa; p < 0.001). When using the 10°AI, the tensile stress was much higher at PP and middle phalanges (MP) of the same toe, measuring 147.58 and 160.58 MPa, respectively, versus 59.44 and 74.95 MPa at corresponding joints in the NSF (all p < 0.001). Similar results were found for compressive stresses. The NI reduced compressive stress at the second PP (-65.12 MPa) compared to the NSF (-113.23 MPa) and the 10°AI (-142 MPa) (all p < 0.001). The von Mises stresses within the implant were also significantly lower when using NI versus 10°AI (p < 0.001). Therefore, we do not recommend performing a PIPJA using the 10°AI due to the increase in stress concentration primarily at the second PP and MP, which could promote implant breakage.

Influence of the center of pressure on baropodometric gait pattern variations in the adult population with flatfoot: A case-control study
(Frontiers Media, 2023-03-09) Padrón, Luis; Bayod, Javier; Becerro-de-Bengoa-Vallejo, Ricardo; Losa-Iglesias, Marta; López-López, Daniel; Casado-Hernández, Israel
Background: Adult flatfoot is considered an alteration in the foot bone structure characterized by a decrease or collapse of the medial arch during static or dynamic balance in the gait pattern. The aim of our research was to analyze the center of pressure differences between the population with adult flatfoot and the population with normal feet. Methods: A case-control study involving 62 subjects was carried out on 31 adults with bilateral flatfoot and 31 healthy controls. The gait pattern analysis data were collected employing a complete portable baropodometric platform with piezoresistive sensors. Results: Gait pattern analysis showed statistically significant differences in the cases group, revealing lower levels in the left foot loading response of the stance phase in foot contact time (p = 0.016) and contact foot percentage (p = 0.019). Conclusion: The adult population with bilateral flatfoot evidenced higher contact time data in the total stance phase compared to the control group, which seems to be linked to the presence of foot deformity in the adult population. Keywords: adult flatfoot; foot; gait patterns; musculoskeletal diseases; stance phase gait.

(Salisbury : Tissue Viability Society,, 2022) Navarro-Flores, Enmanuel; Losa-Iglesias, Marta; Casado-Hernández, Israel; Becerro-de-Bengoa-Vallejo, Ricardo; Romero-Morales, Carlos; Palomo-López, Patricia; López-López, Daniel; Jiménez-Cebrián, Ana María
Background: The footwear assessment tool was designed to advise an appropriate footwear for each situation and patient. Footwear alterations structures can influence in musculoskeletal disorders, developing foot ulcers, increase the peak plantar pressure, bacterial growth, low back pain. Methods: To validate the study 101 subjects were recruited. The study was tested by two expert podiatrists using the tool for the assessment of footwear characteristics that is composed by five domains, fit, general features, general structure, motion control properties and cushioning system. Each domain analyzes different shoe items. Results: An excellent agreement between the test-retest. A suitable Cronbach's α was suggested for the five domains of fit (α = 0.952), general features (α = 0.953), general structure (α = 0.947), motion control properties (α = 0.951), and cushioning system (α = 0.951). Test-retest reliability was excellent for all domains. There were no significant differences between any domain (p > 0.05). T

(Pully, Switzerland : Frontiers Research Foundation, 2022) Losa-Iglesias, Marta; Jimenez-Fernandez, Raquel; Corral-Liria, Inmaculada; Herraiz-Soria, Elena; Rodriguez-Vazquez, Rocio; Becerro-De-Bengoa-Vallejo, Ricardo
Background: The coronavirus 2019 (COVID-19) pandemic has prompted several changes in teaching methods in addition to the ways of learning by students. Objective: To check whether a relationship between factors, such as resilience, self-esteem, depression, anxiety, academic stressors, and a change in teaching methods and learning since the first epidemic outbreak exists. Materials and methods: This study was a cross-sectional descriptive one with a non-random sample of nursing degree teachers who did or did not participate in clinical activities but had been teaching online since the start of the pandemic. Data were collected with online questionnaires validated for self-completion with Google Forms. Results: Regarding the analysis of the descriptive data of each scale, we can verify that data indicate very high levels of resilience and self-esteem in the normal range with minimal levels of depression, moderate anxiety, and finally not worrying about sources of stress in teachers. Also, negative correlations were found between the 10 Connor-Davidson Resilience Scale, Beck Depression Inventory (BDI 2), Beck Anxiety Inventory (BAI), and Scale of Sources of Stress in Teachers with a statistical significance of p < 0.001. The Rosenberg Self-Esteem Scale also showed negative correlations with the three previously mentioned scales with a statistical significance of p < 0.001. Finally, positive correlations between the Beck (BDI 2), Beck (BAI), and Sources of Stress in Teachers scales and between the Rosenberg Self-Esteem scale and the 10 CD RISC scale were found (p < 0.001). Discussion: Our study shows that nursing degree teachers combine teaching with activities and presented moderate levels of anxiety, depression, and tolerance to academic stressors and were able to maintain optimal levels of self-esteem and resilience, indicating that these two factors act as protectors against these stressors.
