Variability of the lower limb symmetry index associated with the gait parameters in the overweight adult population with flatfoot: a case-control study

Background: Adult acquired flatfoot is characterized by a medial arch collapse during monopodal support in the stance phase, developing eversion of the calcaneus and abduction of the forefoot linked to the hindfoot. The purpose of our research was to analyze the dynamic symmetry index in the lower limbs comparing patients with flatfoot and normal foot. Methods: A case-control study was carried out with a sample of 62 participants divided into two groups consisting of 31 participants were overweight with bilateral flatfoot and 31 participants with healthy feet. A portable plantar pressure platform with piezoresistive sensors was used to measure the load symmetry index in the lower limbs in the foot areas and gait phases. Results: Gait pattern analysis showed statistically significant differences in the symmetry index for lateral load (p = 0.004), the initial contact phase (p = 0.025) and the forefoot phase (p < 0.001). Conclusion: The adults were overweight with bilateral flatfoot evidenced alterations in the symmetry index in the lateral load and in the initial contact and flatfoot contact phases, showing greater instability in overweight adult flatfoot compared to the people with normal feet.

Influence of the center of pressure on baropodometric gait pattern variations in the adult population with flatfoot: A case-control study

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.

Stressors and difficulties perceived during the pandemic in the teaching activity of nursing professors

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.

Tweetable abstract

Nursing teachers presented moderate levels of anxiety, depression, and academic stressors due to optimal levels of self-esteem and resilience.

BURNOUT, RESILIENCE AND PSYCHOLOGICAL FLEXIBILITY IN FRONTLINE NURSES DURING THE ACUTE PHASE OF THE COVID-19 PANDEMIC (2020) IN MADRID-SPAIN

Background

In 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.

Aim

The 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.

Methods

This 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.

Results

The 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.

Conclusions

There 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 Management

The scores show the necessity to implement preventive measures to avoid fatal psychological consequences for nurses.

Holistic nursing care for people diagnosed with an eating disorder: A qualitative study based on patients and nursing professionals' experience

PURPOSE

To analyze eating disorder patients and nursing professionals' views and experience of the relationship-based care established.

DESIGN AND METHODS

A qualitative study that employs an interpretative phenomenological analysis. Nineteen patients and 19 nurses participated in the research through interviews and narrations.

FINDINGS

Nurses' help is both unexpected and relevant during the patients' recovery process. They provide care not focusing just on nutritional aspects, other factors such as mutual help, the psychological, emotional, social, and personal aspects are highlighted.

PRACTICE IMPLICATIONS

This study provides a deep understanding of the relationship-based care established that makes it possible to expand knowledge and to individualize the care provided.

Use of the Barthel Index to Assess Activities of Daily Living before and after SARS-COVID 19 Infection of Institutionalized Nursing Home Patients

The objective of the present study was to evaluate the activities of daily living (ADLs) using the Barthel Index before and after infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and also to determine whether or not the results varied according to gender. The ADLs of 68 cohabiting geriatric patients, 34 men and 34 women, in two nursing homes were measured before and after SARS-CoV-2 (Coronavirus 2019 (COVID-19)) infection. COVID-19 infection was found to affect the performance of ADLs in institutionalized elderly in nursing homes, especially in the more elderly subjects, regardless of sex. The COVID-19 pandemic, in addition to having claimed many victims, especially in the elderly population, has led to a reduction in the abilities of these people to perform their ADLs and caused considerable worsening of their quality of life even after recovering from the disease.

Age-based inter-subject variability in platelet and white blood cell concentrations of platelet-rich plasma prepared using a new application to blood separation system

The benefit of autologous platelet‐rich plasma (PRP) treatment is still under discussion. Variations in PRP products, consequence of the lack of a standardised protocol for the multitude of commercially available blood separation systems and the lack of knowledge of the optimal composition of PRP or its suitability for the proposed indication are some of the reasons behind clinical inconsistencies. The impact of inter‐subject variability in PRP has received less attention in comparison. The purpose of this study was to determine the inter‐subject variability, based on age, in the concentrates prepared by a new blood concentration system. Twenty‐six healthy volunteers of both genders (29‐93 years) were enrolled. Whole blood (WB) was collected from each participant to prepare PRP using the Easy PRP kit. Platelets and white blood cells (WBC) from WB and PRP were analysed after split population by age; patients younger than 65 years (n = 13) and patients ≥65 years old (n = 13). Among the demographic characteristics tested, only age was significantly different between the groups. Cell capture efficiency of the system was specific for each type of blood cell and identical for both age groups. Platelets and WBC in PRP were higher than in WB (P < .001). In WB, platelets and WBC concentrations were significantly lower in older group (P ≤ .035). These differences persisted in the prepared PRP (P ≤ .004). The ageing of population has a strong influence on the haematocrit and therefore on the composition of PRP. Because the efficiency of blood separator system seems to be constant across individuals, the inter‐subject haematocrit variability based on age could be used as a predictor of resulting PRP. The clinical application of PRP should be restricted to the specific cell capture capacity of the different commercial devices.

[The experience of caring for people with eating disorders: a qualitative study of nurses' perspectives]

BACKGROUND

Eating disorders (ED) are an increasingly prevalent problem with serious consequences for different spheres of life. This study aims to analyze nurses' perspectives and experiences of the care provided to people diagnosed with an ED.

METHODS

Hermeneutical phenomenological qualitative study. Nineteen nurses from Alcalá de Henares (Madrid) collab-orated in the research sharing their experience through interviews and stories, which were recorded, transcribed and analyzed thematically.

RESULTS

Three issues were obtained: a fight between the heart and mind, conscious reflection: the body says what the head keeps silent and learning how to care holistically. Nurses experience a struggle with their feelings of transference / countertransference when caring for patients. They set out to combine skills acquired from their experience with new research, without losing sight of the individual and the factors involved (family, society and work), which are key to understand the patient's experience and recovery.

CONCLUSIONS

Nurses need more specialization, ongoing training, coordination and teamwork with other professionals to provide people with holistic care. Gender perspectives should be taken into account to enable care to be adapted to the needs of men and women. This study takes an in-depth look at the care relationship between nurse and patient, to obtain a hitherto unknown perspective of care, which makes it possible to expand knowledge and individualize the care provided.

Degree of Impact of Tailor's Bunion on Quality of Life: A Case-Control Study

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.

Comparative Study of Intramedullary Hammertoe Fixation

BACKGROUND

Temporary Kirschner wire fixation (K-wire) is a widely used, low-cost fixation method for the correction of hammertoe deformity. Reported complications associated with K-wires prompted the development of new implants over the past decade. However, there is a lack of literature on comparative studies analyzing functional outcomes using validated questionnaires. The purpose of this study was to analyze functional outcomes in patients who had undergone proximal interphalangeal joint fusion using 2 types of intramedullary implant, the Smart Toe and the TenFuse, and to compare them with the outcomes in patients treated with standard K-wire fixation.

METHODS

A retrospective review of operative hammertoe correction by a single surgeon was performed in 96 patients followed for more than 12 months. Functional outcome was assessed using the Foot Function Index (FFI), the Short Form 36 (SF-36), and the 10-point visual analog scale (VAS) validated questionnaires. Complications and fusion rates were also evaluated. Several patients in the study underwent corrections in different toes; thus, a total of 186 toes were included in the study. From these, 65 toes (34.9%) were treated with K-wire fixation, 94 (50.5%) with Smart Toe titanium implant, and 27 (14.5%) with TenFuse allograft implant.

RESULTS

No statistically significant differences in functional outcome and incidence of complications were observed among the 3 fixation groups, although the 2 intramedullary implants were associated with greater fusion rates and patient satisfaction. Breakage of the Smart Toe implant was significantly higher than that of the other fixations, with 10.6% of implants breaking within the first year postoperatively. SF-36 and VAS scores decreased 12 months after surgery for the 3 types of fixation, with no statistically significant differences observed.

CONCLUSION

The use of Smart Toe and TenFuse implants provided operative outcomes comparable to those obtained using a K-wire fixation and slightly better patient satisfaction. Our results suggest that utilization of these implants for hammertoe correction was a reasonable choice that provided good alignment, pain reduction, and improved function at final follow-up. However, they are more expensive than K-wires. For this reason, in-depth cost-benefit studies would be required to justify their use as a standard treatment.

Impact of shoe size in a sample of elderly individuals

Summary Introduction: The use of an improper shoe size is common in older people and is believed to have a detrimental effect on the quality of life related to foot health. The objective is to describe and compare, in a sample of participants, the impact of shoes that fit properly or improperly, as well as analyze the scores related to foot health and health overall. Method: A sample of 64 participants, with a mean age of 75.3±7.9 years, attended an outpatient center where self-report data was recorded, the measurements of the size of the feet and footwear were determined and the scores compared between the group that wears the correct size of shoes and another group of individuals who do not wear the correct size of shoes, using the Spanish version of the Foot Health Status Questionnaire. Results: The group wearing an improper shoe size showed poorer quality of life regarding overall health and specifically foot health. Differences between groups were evaluated using a t-test for independent samples resulting statistically significant (p<0.05) for the dimension of pain, function, footwear, overall foot health, and social function. Conclusion: Inadequate shoe size has a significant negative impact on quality of life related to foot health. The degree of negative impact seems to be associated with age, sex, and body mass index (BMI).

Reduction in the incidence of pressure ulcers upon implementation of a reminder system for health-care providers

PURPOSE

To measure the clinical impact of the introduction of a reminder system for healthcare professionals to alert patients who are at risk for pressure ulcers (PU).

METHODS

This was a pre- and post-test study of patients who were discharged from 6 medical-surgical units of the University Hospital of Fuenlabrada in 2009 and 2010. Beginning in January 2010, implementation of an on-screen list of reminders was automatically updated daily on the units' computers including patient arrival date, last assessment of ulceration risk and location of any PU. The cumulative incidence of PU was measured for patients discharged in 2009 (group A: healthcare professionals were not exposed to on-screen reminder) and 2010 (group B: healthcare professionals were exposed to on-screen reminder list). The relative risk (RR) was estimated. The study was completed with a stratified analysis and binary logistic regression.

RESULTS

In group A, there were 84 cases of PU among 9263 patients discharged (0.9%); whereas in group B, there were 59 cases among 9220 patients discharged (0.6%). The RR of PU for group B/group A was 0.706 (p=0.038). In the logistic regression analysis, after adjusting for study variables, the odds ratio of PU B/A was 0.558.

CONCLUSION

A list of on-screen reminders at the beginning of a healthcare professional's shift to inform them of patients at risk for developing a PU was effective at reducing the incidence of these clinical burdens.

Influence of first proximal phalanx geometry on hallux valgus deformity: a finite element analysis

Hallux abducto valgus (HAV), one of the most common forefoot deformities, occurs primarily in elderly women. HAV is a complex disease without a clearly identifiable cause for its higher prevalence in women compared with men. Several studies have reported various skeletal parameters related to HAV. This study examined the geometry of the proximal phalanx of the hallux (PPH) as a potential etiologic factor in this deformity. A total of 43 cadaver feet (22 males and 21 females) were examined by means of cadaveric dissection. From these data, ten representative PPHs for both genders were selected, corresponding to five percentiles for males (0, 25, 50, 75, and 100%) and five for females. These ten different PPHs were modeled and inserted in ten foot models. Stress distribution patterns within these ten PPH models were qualitatively compared using finite element analysis. In the ten cases analyzed, tensile stresses were larger on the lateral side, whereas compressive stresses were larger on the medial side. The bones of males were larger than female bones for each of the parameters examined; however, the mean difference between lateral and medial sides of the PPH (mean ± SD) was larger in women. Also the shallower the concavity at the base of the PPH, the larger the compressive stresses predicted. Internal forces on the PPH, due to differences in length between its medial and lateral sides, may force the PPH into a less-stressful position. The geometry of the PPH is a significant factor in HAV development influencing the other reported skeletal parameters and, thus, should be considered during preoperative evaluation. Clinical assessment should evaluate the first ray as a whole and not as isolated factors.

Advantages and Drawbacks of Proximal Interphalangeal Joint Fusion Versus Flexor Tendon Transfer in the Correction of Hammer and Claw Toe Deformity. A Finite-Element Study

Correction of claw or hammer toe deformity can be achieved using various techniques, including proximal interphalangeal joint arthrodesis (PIPJA), flexor digitorum longus tendon transfer (FDLT), and flexor digitorum brevis transfer. PIPJA is the oldest technique, but is associated with significant complications (infection, fracture, delayed union, and nonunion). FDLT eliminates the deformity, but leads to loss of stability during gait. Flexor digitorum brevis tendon transfer (FDBT) seems to be the best surgical alternative, but it is a recent technique with still limited results. In this work, these three techniques have been analyzed by means of the finite-element method and a comparative analysis was done with the aim of extracting advantages and drawbacks. The results show that the best technique for reducing dorsal displacement of the proximal phalanx is PIPJA (2.28 mm versus 2.73 mm for FDLT, and 3.31 mm for FDBT). However, the best technique for reducing stresses on phalanges is FDLT or FDBT (a reduction of approximately 35% regarding the pathologic case versus the increase of 7% for the PIPJA in tensile stresses, and a reduction of approximately 40% versus 25% for the PIPJA in compression stresses). Moreover, the distribution of stresses in the entire phalanx is different for the PIPJA case. These facts could cause problems for patients, in particular, those with pain in the surgical toe.
