Analyzing the Thermal Characteristics of Three Lining Materials for Plantar Orthotics.

INTRODUCTION: The choice of materials for covering plantar orthoses or wearable insoles is often based on their hardness, breathability, and moisture absorption capacity, although more due to professional preference than clear scientific criteria. An analysis of the thermal response to the use of these materials would provide information about their behavior; hence, the objective of this study was to assess the temperature of three lining materials with different characteristics. MATERIALS AND METHODS: The temperature of three materials for covering plantar orthoses was analyzed in a sample of 36 subjects (15 men and 21 women, aged 24.6 ± 8.2 years, mass 67.1 ± 13.6 kg, and height 1.7 ± 0.09 m). Temperature was measured before and after 3 h of use in clinical activities, using a polyethylene foam copolymer (PE), ethylene vinyl acetate (EVA), and PE-EVA copolymer foam insole with the use of a FLIR E60BX thermal camera. RESULTS: In the PE copolymer (material 1), temperature increases between 1.07 and 1.85 °C were found after activity, with these differences being statistically significant in all regions of interest (p < 0.001), except for the first toe (0.36 °C, p = 0.170). In the EVA foam (material 2) and the expansive foam of the PE-EVA copolymer (material 3), the temperatures were also significantly higher in all analyzed areas (p < 0.001), ranging between 1.49 and 2.73 °C for EVA and 0.58 and 2.16 °C for PE-EVA. The PE copolymer experienced lower overall overheating, and the area of the fifth metatarsal head underwent the greatest temperature increase, regardless of the material analyzed. CONCLUSIONS: PE foam lining materials, with lower density or an open-cell structure, would be preferred for controlling temperature rise in the lining/footbed interface and providing better thermal comfort for users. The area of the first toe was found to be the least overheated, while the fifth metatarsal head increased the most in temperature. This should be considered in the design of new wearables to avoid excessive temperatures due to the lining materials.

Conventional vs. diode laser stapedotomy: audiological outcomes and clinical safety.

PURPOSE: To compare the hearing results and clinical safety of patients undergoing stapes surgery with conventional technique and diode laser. METHODS: Retrospective observational study, which included patients treated with primary stapes surgery performed between January 2009 and January 2020. Three audiometric measurements (PTA, GAP and SDS) were evaluated as main results, evaluated by analysis of covariance (controlling the preoperative value). Intraoperative and postoperative complications were also analyzed. Outcomes were measured 6 months (± 1 month) after surgery. RESULTS: 153 cases were included, 97 operated with conventional technique and 56 with laser technique. Postoperative GAP ≤ 10 dB was obtained in 85.6% of the total sample, 82.5% in the conventional technique and 91.1% in the laser technique. Analysis of covariance showed no significant differences in the three surgery outcomes between the two groups (PTA, p = 0.277; GAP, p = 0.509 and SDS, p = 0.530). Regarding surgical complications, sensorineural damage was higher in the conventional technique group (p = 0.05). On the other hand, there were four cases of facial paresis, all in the laser group, three of them with the 980 nm laser. CONCLUSIONS: Stapedotomy offered a high percentage of hearing success in the two groups studied. There were no significant differences in audiometric result, but there was a differential presentation of complications, being more frequent sensorineural hearing loss in the conventional technique group and facial paresis in the laser group.

Clinical experience with the Nurotron™ cochlear implant in a Spanish-speaking postlingual population: Clinical safety and audiological results.

OBJECTIVE: to assess clinical safety and postoperative audiological outcomes in postlingual deafness Spanish speaking patients, who underwent surgery with Nurotron™ cochlear implant. MATERIAL AND METHODS: Retrospective descriptive case series study. We performed follow-up of complications and audiological measurements before and after cochlear implantation. Patients with bilateral severe to profound sensorineural hearing loss or patients with unilateral deafness with/without tinnitus were included. Repeated-measures within-subjects for assess pure tone thresholds and speech performance (bilingual test) with a detailed monitoring to establish security or adverse effects were performed. Analysis of variance tests, repetitive measures, were used for statistical analysis. RESULTS: 31 patients were included, 17 (54.8%) men and 14 (45.2%) women. Mean age at the time of surgery was 49.82 ± 18.8 years. The mean follow-up of the group was 31.56 ± 9.57 months (minimum = 19.6 months and maximum = 52.50 months). As major complication one patient (3.23%) had a hard failure that required removal and re-implantation. 25.8% of the patients presented minor complications, the most frequent being vertigo/unsteadiness in 22.6%. The mean of language discrimination (free field at 65 dB SPL) was 62.19% ± 16.66; being 69.82% ± 7.35 in the group of severe to profound bilateral sensorineural hearing loss. A statistically significant reduction was observed in patients with tinnitus, assessed using the visual analogue scale, preoperative = 7.2 ± 1,6 vs postoperative (18months postoperative) = 1.7 ± 1.3 (p < .001). CONCLUSIONS: The Nurotron™ cochlear implant shows satisfactory audiological results, in accordance with what has been reported in the literature. Minor complications were similar to previous studies, but the percentage of hard failure should continue to be observed, which was higher than other reports with comparable follow-up.

Validity and reliability of the Berlin questionnaire for the detection of moderate or severe obstructive sleep apnea in patients aged 40 years or older detected from primary care.

Background: The obstructive sleep apnea syndrome (OSA) is a highly prevalent condition. In Spain and other countries, only 5%-9% of patients with OSA have been diagnosed and treated. The lack of accessibility to diagnosis is considered the main cause of this situation through easy-to-use screening instruments, it is necessary to check their validity and reliability in the context where they are to be used. Objective: To validate the Spanish translation of the Berlin questionnaire for screening for moderate or severe OSA in patients aged 40 years or more detected in primary care. Methods: A descriptive observational study, with a first qualitative phase of transcultural adaptation to Spanish using the translation-back-translation method. Setting: primary care level of the Spanish National Health System. A total of 255 patients recruited from 7 healthcare centers completed the study. The Berlin questionnaire was administered to the recruited patients, and subsequently, a respiratory polygraphy was performed to confirm the diagnosis of OSA. The concurrent criterion validity of the questionnaire and its reliability in terms of internal consistency and reproducibility (intra-observer agreement) were analyzed. Results: The patients' mean age was 54.76 years (SD: 6.57; 95% CI: 53.53-54.99), and 54.12% were men (95% CI: 47.96-60.27). We found that 61.57% (95% CI: 55.57-67.57) presented OSA (apnea-hypopnea index-AHI >5), and 45.5% (95% CI: 17.05-57.92) presented moderate or severe (AHI >15) OSA. The Berlin questionnaire, with a cut-off point of 4.5, showed a sensitivity of 76.77% (95% CI: 67.94-85.59), a specificity of 74.49% (95% CI: 65.35-83.63), a positive predictive value of 75.25% (95% CI: 66.34-84.16), a negative predictive value of 76.04% (95% CI: 66.98-85.10), and an area under the curve of 0.786 (95% CI: 0.721-0.851). Cronbach's alpha coefficient was 0.730 (95% CI: 0.668-0.784), and the Kappa index was 0.739 (95% CI, 0.384-1.000). Conclusion: The Spanish adaptation of the Berlin questionnaire has good validity and reliability as a test for the diagnostic screening of moderate or severe OSA in patients aged 40 years or older. The findings of our study confirm that primary care physicians should use such screening tools to predict OSA.

Piloting the informed health choices resources in Barcelona primary schools: A mixed methods study.

INTRODUCTION: The main objective of the Informed Health Choices (IHC) project is to teach people to assess treatment claims and make informed health choices. For this purpose, the IHC learning resources were developed for primary school children. The aim of this study is to explore students' and teachers' experience when using the IHC resources in primary schools in Barcelona (Spain). METHODS: We conducted a mixed methods study for piloting the IHC resources in a convenience sample of primary schools in Barcelona. The intervention included a workshop with teachers, and nine lessons with students. We collected data using multiple approaches. We performed quantitative and qualitative analyses, and integrated the findings in a joint display. Finally, we formulated recommendations for using the IHC resources in this setting. RESULTS: Two schools, with a total of 143 students in 4th and 5th grade and six teachers, participated in the study. One school followed the suggested IHC teaching plan and competed all the lessons; the other school modified the plan substantially and did not complete all the lessons. Overall, students and teachers from both schools understood, were interested in, and were able to apply the content of the lessons. During the lessons, the textbook was useful for students; nevertheless, for the teachers, the usefulness of the IHC resources was variable. Teachers adapted the IHC resources to increase student participation and used Information and Communications Technologies tools. We observed more facilitators than barriers to teach the lessons. The teachers suggested some ideas to improve the lessons based on activities they developed and implemented. The integration analysis showed great convergence of the quantitative and qualitative findings. We propose seven recommendations for using the IHC resources in this setting. CONCLUSIONS: Students and teachers from primary schools in Barcelona showed a positive experience when using IHC resources; however, these resources should be adapted to promote classroom participation.

Thermal Differences in the Plantar Surface Skin of the Foot after Using Three Different Lining Materials for Plantar Orthotics.

The lining materials of plantar orthoses are chosen for their hardness, breathability, and moisture absorption, but without there being any clear scientific criterion. Thermographic analysis would provide information about the thermal response of the sole of the foot, and would thereby allow the choice to be adapted in accordance with this criterion. The objective of this study was to evaluate plantar temperatures after the use of three materials with different characteristics. Plantar temperatures were analyzed by using a FLIR E60BX thermographic camera on 36 participants (15 men and 21 women, 24.6 ± 8.2 years old, 67.1 ± 13.6 kg, and 1.7 ± 0.09 m). Measurements were made before and after (3 h) the use of three lining materials for plantar orthoses (Material 1: PE copolymer; Material 2: EVA; Material 3: PE-EVA copolymer) on different days. For Material 1 (PE), the temperature under the heel was significantly higher after exercise, increasing from 30.8 ± 2.9 °C to 31.9 ± 2.8 °C (p = 0.008), and negative correlations were found between room temperature and the pre/post temperature difference for the big toe (r = -0.342, p = 0.041) and the 1st metatarsal head (r = -0.334, p = 0.046). No significant pre/post temperature differences were found with the other materials. The three materials thermoregulated the plantar surface efficiently by maintaining the skin temperature at levels similar to those evaluated before exercise. If PE is used as a lining material, it should be avoided for the heel area in patients with hyperhidrosis or those with a tendency to suffer from skin pathologies due to excess moisture.

Association between Clinical Frailty Scale (CFS) and clinical presentation and outcomes in older inpatients with COVID-19.

BACKGROUND: Frailty is a physiological condition characterized by a decreased reserve to stressors. In patients with COVID-19, frailty is a risk factor for in-hospital mortality. The aim of this study was to assess the relationship between clinical presentation, analytical and radiological parameters at admission, and clinical outcomes according to frailty, as defined by the Clinical Frailty Scale (CFS), in old people hospitalized with COVID-19. MATERIALS AND METHODS: This retrospective cohort study included people aged 65 years and older and admitted with community-acquired COVID-19 from 3 March 2020 to 31 April 2021. Patients were categorized using the CFS. Primary outcomes were symptoms of COVID-19 prior to admission, mortality, readmission, admission in intensive care unit (ICU), and need for invasive mechanical ventilation. Analysis of clinical symptoms, clinical outcomes, and CFS was performed using multivariable logistic regression, and results were expressed as odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Of the 785 included patients, 326 (41.5%, 95% CI 38.1%-45.0%) were defined as frail (CFS ≥ 5 points): 208 (26.5%, 95% CI 23.5%-29.7%) presented mild-moderate frailty (CFS 5-6 points) and 118 (15.0%, 95% CI 12.7%-17.7%), severe frailty (7-9 points). After adjusting for epidemiological variables (age, gender, residence in a nursing home, and Charlson comorbidity index), frail patients were significantly less likely to present dry cough (OR 0.58, 95% CI 0.40-0.83), myalgia-arthralgia (OR 0.46, 95% CI 0.29-0.75), and anosmia-dysgeusia (OR 0.46, 95% CI 0.23-0.94). Confusion was more common in severely frail patients (OR 3.14; 95% CI 1.64-5.97). After adjusting for epidemiological variables, the risk of in-hospital mortality was higher in frail patients (OR 2.79, 95% CI 1.79-4.25), including both those with mild-moderate frailty (OR 1.98, 95% CI 1.23-3.19) and severe frailty (OR 5.44, 95% CI 3.14-9.42). Readmission was higher in frail patients (OR 2.11, 95% CI 1.07-4.16), but only in mild-moderate frailty (OR 2.35, 95% CI 1.17-4.75).. CONCLUSION: Frail patients presented atypical symptoms (less dry cough, myalgia-arthralgia, and anosmia-dysgeusia, and more confusion). Frailty was an independent predictor for death, regardless of severity, and mild-moderate frailty was associated with readmission.

Efficacy of Dry Needling for Chronic Low Back Pain: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Objective: To evaluate the current evidence of the effectiveness of dry needling in patients with chronic low back pain (LBP). Methods: PubMed, Medline, ScienceDirect, Web of Science, CINAHL and PEDro databases were searched until 2020. Study selection: Randomised controlled trials (RCTs) that used dry needling as the main treatment and which included participants diagnosed with chronic LBP. Data extraction: Two reviewers independently screened articles, scored methodologic quality, and extracted data. The primary outcomes were pain intensity and functional disability at post-intervention and follow-up. Results: A total of 8 RCTs involving 414 patients were included in the meta-analysis. All trials examined the efficacy of DN in patients with chronic LBP. Results suggested that compared with other treatments, dry needling combined was more effective in alleviating the pain intensity of LBP post-intervention (standardised mean difference [SMD], -0.42; 95% confidence interval [CI], -0.79 to -0.05; P = .03) and at short- term (SMD -0.99, 95% CI -1.61 to -0.37, P = .002). Conclusion: Current evidence showed that dry needling, especially if associated with other therapies, could be recommended to relieve the pain intensity of LBP at post-intervention and at short-term follow up. There is no evidence that dry needling alone or in combination improves disability at post-immediate or at short-term follow up. Registration: This review was registered on PROSPERO (PROSPERO CRD42020215781) and was aligned with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting systematic reviews that evaluate healthcare interventions.

Clinical utility of liquid biopsy and integrative genomic profiling in early-stage and oligometastatic cancer patients treated with radiotherapy.

BACKGROUND: Liquid biopsy and Integrative Genomic Profiling (IGP) are yet to be implemented into routine Radiation Oncology. Here we assess the utility of germline, tumour and circulating cell-free DNA-based genomic analyses for the clinical management of early-stage and oligometastatic cancer patients treated by precision radiotherapy. METHODS: We performed germline, tissue- and liquid biopsy NGS panels on 50 early-stage/oligometastatic cancer patients undergoing radiotherapy. We also monitored ctDNA variants in serial liquid biopsies collected during radiotherapy and follow-up and evaluated the clinical utility of such comprehensive approach. RESULTS: The integration of different genomic studies revealed that only 1/3 of the liquid biopsy variants are of tumour origin. Altogether, 55 tumour variants (affecting 3/4 of the patients) were considered potentially actionable (for treatment and prognosis), whereas potential follow-up biomarkers were identified in all cases. Germline cancer-predisposing variants were present in three patients, which would have not been eligible for hereditary cancer testing according to clinical guidelines. The presence of detectable ctDNA variants before radiotherapy was associated with progression-free survival both in oligometastatic patients and in those with early-stage. CONCLUSIONS: IGP provides both valuable and actionable information for personalised decision-making in Radiation Oncology.

Estudio descriptivo de los resultados obstétricos y neonatales en dos modelos de asistencia al parto en primíparas

Resumen: Introducción: En el siglo XX el parto pasó de ser atendido en casa al ámbito hospitalario. Se adoptaron de forma acrítica intervenciones inapropiadas e innecesarias que condujeron a una deshumanización del parto. Este es el modelo que existe actualmente en la mayoría de los hospitales españoles y que fue cuestionado por la OMS ya en 1996. Objetivo: Describir las diferencias que existen en los resultados obstétricos y neonatales en primíparas en dos modelos distintos de asistencia al parto (biomédico y humanizado). Método: Se llevó a cabo un estudio descriptivo, de corte transversal. Se obtuvo una muestra por conveniencia de 205 primíparas, 110 del modelo biomédico y 95 del humanizado. Se compararon los resultados obstétricos y neonatales en dos hospitales con modelos diferentes de asistencia al parto en España. Resultados: En el modelo humanizado de asistencia al parto se obtuvieron unos mejores resultados obstétricos (inicio espontáneo, parto eutócico, periné íntegro o desgarro de I grado y menos episiotomías) que en el biomédico. No hubo diferencias en los resultados neonatales. Conclusión: Los beneficios de instaurar un modelo humanizado de asistencia al parto deberían ser considerados por los responsables de políticas sanitarias y reflejados en la mujer y su criatura.

Intervenções inadequadas e desnecessárias foram adotadas acriticamente, levando a uma desumanização do parto. Este é o modelo que existe atualmente na maioria dos hospitais espanhóis e que foi questionado pela Organização Mundial da Saúde já em 1996. Objetivo: O objetivo principal desse estudo é descrever as diferenças existentes nos resultados obstétricos e neonatais em primíparas em dois modelos distintos de assistência ao parto (biomédico e humanizado). Método: Foi realizado um estudo descritivo, transversal. Obteve-se uma amostra por conveniência de 205 primíparas, 110 do modelo biomédico e 95 do modelo humanizado. Os resultados obstétricos e neonatais foram comparados em dois hospitais com diferentes modelos de assistência ao parto na Espanha. Resultados: No modelo humanizado de assistência ao parto obtiveram-se melhores resultados obstétricos (início espontâneo, parto eutócico, períneo íntegro ou laceração grau I e menos episiotomias) do que no modelo biomédico. Não houve diferença nos resultados neonatais. Conclusão: Os benefícios da implementação de um modelo humanizado de assistência ao parto devem ser considerados pelos formuladores de políticas de saúde e refletidos na mulher e em seu bebê.

Abstract: Introduction: In the 20th century, childbirth went from being attended at home to the hospital setting. Inappropriate and unnecessary interventions were uncritically adopted, leading to a dehumanization of childbirth. This is the model that currently exists in most Spanish hospitals, which has been questioned by the World Health Organization as early as 1996. Objective: The aim is to describe the differences in obstetrical and neonatal results across two different models of maternity care (biomedical model and humanised birth). Method: A correlational descriptive and multicenter study was carried out. A convenience sample of 205 primiparous women, 110 biomedical model and 95 humanised model, were recruited. Obstetrical and neonatal results were compared in two hospitals with different models of maternity care in Spain. Results: The humanised model of maternity care produces better obstetrical outcomes (spontaneous beginning of labour, normal vaginal birth, intact perineum and I degree tear and less episiotomies) than the biomedical model. There were no differences in neonatal outcomes. Conclusion: The benefits of implementing a humanised model of delivery care should be considered by health policy makers and reflected in the woman and her baby.

The usefulness of the Spanish version of the STOP-Bang questionnaire for screening for moderate or severe sleep apnea syndrome in primary care.

Rationale: Sleep apnea-hypopnea syndrome (OSA) is a highly prevalent disease and has been related to cardiovascular diseases and occupational and traffic accidents. Currently, it is estimated that there is a significant underdiagnosis of OSA, mainly due to the difficulty accessing the tests for that purpose. Objective: To determine the usefulness of the Spanish version of the STOP-Bang questionnaire (SBQ) for screening for moderate or severe OSA in the adult population attending primary care. Methods: A descriptive observational multicenter study was conducted. Through an opportunistic search, (patients over 18 years old), were recruited in seven primary care centers. The SBQ was applied to them and home respiratory polygraphy (HRP) was subsequently performed to confirm the diagnosis of OSA. The criterion validity of the SBQ was analyzed, comparing the score obtained by the SBQ with the apnea-hypopnea index (AHI) obtained by RP, establishing the diagnosis of OSA for an AHI>5. The reliability of the questionnaire was evaluated. Results: A total of 255 subjects, 54.1% men, with a mean age of 54.76 ± 10 years, were recruited in the study. The results showed that 61.57% (95% Confidence Interval: 55.57-67.57) of the subjects presented OSA, presenting 22.75% (17.57-57.92) a mild OSA (530) (11.54-20.62). The Kuder and Richardson coefficient was 0.623 (0.335-0.788) and Cohen's Kappa coefficient was 0.871 (0.520-1.00; p < 0.001). For moderate/severe OSA screening (AHI>15) the SBQ obtained an ROC curve of 0.769 (0.704-0.833) that with an optimal cutoff of 3, achieved a sensitivity of 84.85% (77.28-92.42) and a specificity of 55.10% (44.74-65.46). Conclusions: The SBQ is very effective for detecting moderate/severe OSA. Its psychometric properties are similar to those obtained in studies on other populations. Because of its ease of use, the SBQ is a very useful tool for primary health care professionals.

mTORC1 controls Golgi architecture and vesicle secretion by phosphorylation of SCYL1.

The protein kinase mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of cell growth and proliferation, supporting anabolic reactions and inhibiting catabolic pathways like autophagy. Its hyperactivation is a frequent event in cancer promoting tumor cell proliferation. Several intracellular membrane-associated mTORC1 pools have been identified, linking its function to distinct subcellular localizations. Here, we characterize the N-terminal kinase-like protein SCYL1 as a Golgi-localized target through which mTORC1 controls organelle distribution and extracellular vesicle secretion in breast cancer cells. Under growth conditions, SCYL1 is phosphorylated by mTORC1 on Ser754, supporting Golgi localization. Upon mTORC1 inhibition, Ser754 dephosphorylation leads to SCYL1 displacement to endosomes. Peripheral, dephosphorylated SCYL1 causes Golgi enlargement, redistribution of early and late endosomes and increased extracellular vesicle release. Thus, the mTORC1-controlled phosphorylation status of SCYL1 is an important determinant regulating subcellular distribution and function of endolysosomal compartments. It may also explain the pathophysiology underlying human genetic diseases such as CALFAN syndrome, which is caused by loss-of-function of SCYL1.

A Dual-Acting Nitric Oxide Donor and Phosphodiesterase 5 Inhibitor Activates Autophagy in Primary Skin Fibroblasts.

Wound healing pathologies are an increasing problem in ageing societies. Chronic, non-healing wounds, which cause high morbidity and severely reduce the quality of life of affected individuals, are frequently observed in aged individuals and people suffering from diseases affected by the Western lifestyle, such as diabetes. Causal treatments that support proper wound healing are still scarce. Here, we performed expression proteomics to study the effects of the small molecule TOP-N53 on primary human skin fibroblasts and keratinocytes. TOP-N53 is a dual-acting nitric oxide donor and phosphodiesterase-5 inhibitor increasing cGMP levels to support proper wound healing. In contrast to keratinocytes, which did not exhibit global proteome alterations, TOP-N53 had profound effects on the proteome of skin fibroblasts. In fibroblasts, TOP-N53 activated the cytoprotective, lysosomal degradation pathway autophagy and induced the expression of the selective autophagy receptor p62/SQSTM1. Thus, activation of autophagy might in part be responsible for beneficial effects of TOP-N53.

Efficacy of e-Health Interventions in Patients with Chronic Low-Back Pain: A Systematic Review with Meta-Analysis.

Introduction: Low-back pain (LBP) is the leading cause of disability worldwide. Around 75-84% of the world's population will experience LBP at some point, establishing it as a major global health problem. e-Health is the remote delivery of therapeutic services, clinical information, and medical care, and may prove a very useful approach to tackle this pathology. Objectives: To evaluate the efficacy of e-health-based interventions in improving the symptoms of chronic LBP. Methods: A systematic review with meta-analysis was performed in PubMed, Web of Science, and PEDro until January 2022 through the assessment of methodological quality of systematic reviews (AMSTAR). Studies were included in which e-health interventions were used as experimental treatment compared to physical therapy to determine changes in back-specific functional status and pain in patients with chronic LBP. Two reviewers examined the sources individually, calculated the risk of bias, and extracted the data (PROSPERO number CRD42022306130). The effect size was calculated using the standardized mean difference (SMD) and its confidence interval (95% CI). Results: A total of 9 randomized controlled trials with 3,180 participants were included. The results of the findings showed an effect of e-health compared to other physical therapy on short-term (SMD = -0.59, 95% CI: -1.77 to 0.59) and intermediate short-term (SMD = -0.40, 95% CI: -0.91 to 0.11) pain intensity and back-specific functional status in the short term (SMD = -0.20, 95% CI: -0.81 to 0.41) and intermediate short term (SMD = -0.30, 95% CI: -0.74 to 0.14). The effect of e-health compared to minimal intervention on short-term intermediate pain intensity (SMD = -0.64, 95% CI: -1.72 to 0.45) and short-term intermediate back-specific functional status (SMD = -0.39, 95% CI: -0.87 to 0.09). Conclusions: e-Health interventions based on self-maintenance and education are as effective on pain and back-specific functional status as other face-to-face or home-based interventions in patients with chronic LBP, with moderate scientific evidence.

Electrical dry needling versus conventional physiotherapy in the treatment of active and latent myofascial trigger points in patients with nonspecific chronic low back pain.

BACKGROUND: Chronic low back pain is considered to be one of the main causes of absenteeism from work and primary and specialized consultations. The symptoms of nonspecific chronic low back pain may be accompanied by the activation of myofascial trigger points in the muscles, together with local and/or referred pain. Electrical dry needling is increasingly used in the treatment of lumbar myofascial pain. Conventional physiotherapy, however, is a popular approach to chronic pathologies, and there is evidence of different modalities of physiotherapy being used in the treatment of chronic low back pain. The aim of this study has been to determine the effectiveness of electrical dry needling versus conventional physiotherapy when applied to active and latent myofascial trigger points in patients with nonspecific chronic low back pain. METHODS: This is a controlled, randomized, two-arm, double-blind study. A total of 92 patients with chronic low back pain (time to onset ≥ 3 months, Roland Morris Disability Questionnaire score ≥ 4) will be recruited from the University of Almería. Participants will be divided into two study groups (n = 40) to receive treatment of low back pain with electrical dry needling and conventional physiotherapy (ischaemic compression, analytic stretching and postural education training dossier). A total of 6 sessions will be administered once a week for 6 weeks. Pain intensity, disability, fear of movement, quality of life, quality of sleep, anxiety and depression, pressure pain threshold, abdominal strength and lumbar mobility will be recorded at 6 weeks (post-immediate) and 2 months after the end of treatment. DISCUSSION: We believe that an approach including electrical dry needling to chronic low back pain dysfunction will be more effective in these patients. The results of this study will inform clinicians on which type of treatment is more beneficial for patients with chronic low back pain. TRIAL REGISTRATION: ClinicalTrials.gov NCT04804228.

Increased abundance of Cbl E3 ligases alters PDGFR signaling in recessive dystrophic epidermolysis bullosa.

In recessive dystrophic epidermolysis bullosa (RDEB), loss of collagen VII, the main component of anchoring fibrils critical for epidermal-dermal cohesion, affects several intracellular signaling pathways and leads to impaired wound healing and fibrosis. In skin fibroblasts, wound healing is also affected by platelet-derived growth factor receptor (PDGFR) signaling. To study a potential effect of loss of collagen VII on PDGFR signaling we performed unbiased disease phosphoproteomics. Whereas RDEB fibroblasts exhibited an overall weaker response to PDGF, Cbl E3 ubiquitin ligases, negative regulators of growth factor signaling, were stronger phosphorylated. This increase in phosphorylation was linked to higher Cbl mRNA and protein levels due to increased TGFß signaling in RDEB. In turn, increased Cbl levels led to increased PDGFR ubiquitination, internalization, and degradation negatively affecting MAPK and AKT downstream signaling pathways. Thus, our results indicate that elevated TGFß signaling leads to an attenuated response to growth factors, which contributes to impaired dermal wound healing in RDEB.

Clima organizacional en el personal de enfermería en una unidad de cuidados intensivos / Organizational environment in nursing staff in an intensive care unit

Introducción: el sistema organizacional genera un determinado clima de trabajo que repercute en las motivaciones de los miembros de la organización y en su comportamiento, por lo que al evaluar el clima organizacional se mide la forma como es percibida la organización. Objetivo: identificar el clima organizacional en el personal de enfermería de la unidad de cuidados intensivos (UCI) del Hospital de Especialidades (HE) No. 14 del Instituto Mexicano del Seguro Social (IMSS), en Veracruz, México. Metodología: estudio observacional, descriptivo y transversal, en el que participaron 49 enfermeras de los turnos matutino, vespertino y nocturno de la UCI del HE No. 14. Durante junio y julio de 2019, se aplicó el instrumento Clima Organizacional de Litwin y Stringer, que contiene 53 ítems en sus 9 dimensiones. Resultados: el nivel promedio global del clima organizacional en la UCI fue de 26.4, lo que lleva a categorizarlo como bueno. Las dimensiones: recompensa, estándares y conflicto obtuvieron una puntuación de 23.5 a 24.8, que se traduce como un promedio regular del clima organizacional. Conclusiones: hay un clima organizacional bueno en el personal de enfermería. El componente que influye de manera positiva es la dimensión cooperación, ya que el trabajador empatiza con sus compañeros de servicio. La dimensión conflicto influye de manera negativa, pues abarca la falta de motivación del personal para realizar su trabajo.

Introduction: Organizational systems generate certain workplace environment that affects the staff members' motivation and their behavior, which is why assessing the organizational environment allows to measure the staff perception on the organization. Objective: To identify the organizational environment of the nursing staff at the Specialty Hospital (SH) No. 14 intensive care unit (ICU) of the National Institute for Social Security (Instituto Mexicano del Seguro Social), in Veracruz, Mexico. Methods: Observational, descriptive, and cross-sectional study, which included 49 nurses from the morning, afternoon and night shifts of the aforementioned ICU. During June and July 2019, it was administered the instrument Organizational Climate by Litwin and Stringer, which contains 53 items in its 9 dimensions. Results: The global average level of the organizational environment in the ICU was 26.4, which leads to categorize it as good. The dimensions reward, standards and conflict obtained a range from 23.5 to 24.8, i.e., a regular average of the organizational environment. Conclusions: There is an organizational environment classified as good in the nursing staff. The component that has a positive influence is the cooperation dimension, since the worker empathizes with his fellow employees. The conflict dimension has a negative influence, given that it includes the lack of motivation of the staff to carry out their work.

ULK1 phosphorylation of striatin activates protein phosphatase 2A and autophagy.

The evolutionarily conserved ULK1 kinase complex acts as gatekeeper of canonical autophagy and regulates induction of autophagosome biogenesis. To better understand control of ULK1 and analyze whether ULK1 has broader functions that are also linked to the later steps of autophagy, we perform comprehensive phosphoproteomic analyses. Combining in vivo with in vitro data, we identify numerous direct ULK1 target sites within autophagy-relevant proteins that are critical for autophagosome maturation and turnover. In addition, we highlight an intimate crosstalk between ULK1 and several phosphatase complexes. ULK1 is not only a PP2A target but also directly phosphorylates the regulatory PP2A subunit striatin, activating PP2A and serving as positive feedback to promote autophagy-dependent protein turnover. Thus, ULK1 and phosphatase activities are tightly coordinated to robustly regulate protein degradation by autophagy.

Perineal protection methods: knowledge and use.

OBJECTIVE: To analyse the knowledge and use of perineal protection methods during the expulsive stage by health professionals involved in childbirth and whether they correspond to the World Health Organization's recommendations. METHOD: This was a cross-sectional descriptive study aimed at health workers involved in births in Spain. RESULTS: Fifty-seven professionals participated in the study: midwives (47%), gynaecologists (25%), nurse residents (14%) and resident physicians (14%) in obstetrics and gynaecology. The degree of knowledge and use of perineal protection methods differed according to the position held and was very limited among gynaecologists and resident physicians. The only method recognized by all positions was "hands on" (p = 0.05). "Hands off " (p = 0.002), "delayed pushing" (p = 0.0001) and "maternal posture" (p = 0.03) were only known to midwives and nurse residents. "Flexion technique" (p = 0.035) and "delayed pushing" (p = 0.011) were used effectively by midwives and nurse residents. "Episiotomy" was erroneously identified as a method to protect the perineum by gynaecologists and resident physicians (p = 0.003). CONCLUSION: The degree of knowledge and use of perineal protection methods by health care professionals does not correspond to the recommendations of the World Health Organization.
