RESUMO
BACKGROUND: Safety is an important consideration in decisions on treatment for patients with moderate-to-severe psoriasis and the study of drug safety is the main purpose of the BIOBADADERM registry. The combination of a biologic agent and a conventional systemic drug [generally methotrexate (MTX)] is a common treatment in clinical practice. However, there is a paucity of evidence from real-world practice on the safety of such combination regimens in the treatment of psoriasis. OBJECTIVES: The primary objective of this study was to ascertain whether the use of regimens combining biologic drugs with MTX in the management of moderate-to-severe psoriasis increases the risk of adverse events (AEs) or serious AEs (SAEs). We compared monotherapy using tumour necrosis factor (TNF), interleukin (IL)-17 and IL-23 inhibitors with the use of the same drugs in combination with MTX. METHODS: Using data from the BIOBADADERM registry, we compared biologic monotherapies with therapies that were combined with MTX. We estimated adjusted incidence rate ratios (aIRR) using a random effects Poisson regression with 95% confidence intervals for all AEs, SAEs, infections and serious infections and other AEs by system organ class. RESULTS: We analysed data from 2829 patients and 5441 treatment cycles, a total of 12 853 patient-years. The combination of a biologic with MTX was not associated with statistically significant increases in overall risk of AEs or SAEs in any treatment group. No increase in the total number of infections or serious infections in patients receiving combined therapy was observed for any group. However, treatment with a TNF inhibitor combined with MTX was associated with an increase in the incidence of gastrointestinal AEs (aIRR 2.50, 95% CI 1.57-3.98; P < 0.002). CONCLUSIONS: The risk of AEs and SAEs was not significantly increased in patients with moderate-to-severe psoriasis receiving different classes of biologic drugs combined with MTX compared with those on biologic monotherapy.

The reaction between 5-acetylbarbituric acid and 4-dimethylthiosemicarbazide or 4-hexamethyleneiminyl thiosemicarbazide produces 5-acetylbarbituric-4-dimethylthiosemicarbazone (H2AcbDM) and 5-acetylbarbituric-4N-hexamethyleneiminyl thiosemicarbazone (H2Acbhexim). Eight new complexes with different copper(II) salts have been prepared and characterized using elemental analysis, molar conductance, UV-Vis, ESI-HRMS, FT-IR, magnetic moment, EPR, and cyclic voltammetry. In addition, three-dimensional molecular structures of [Cu(HAcbDM)(H2O)2](NO3)·H2O (3a), [Cu(HAcbDM)(H2O)2]ClO4 (4), and [Cu(HAcbHexim)Cl] (6) were determined by single crystal X-ray crystallography, and an analysis of their supramolecular structure was carried out. The H-bonded assemblies were further studied energetically using DFT calculations and MEP surface and QTAIM analyses. In these complexes, the thiosemicarbazone coordinates to the metal ion in an ONS-tridentate manner, in the O-enolate/S-thione form. The electrochemical behavior of the thiosemicarbazones and their copper(II) complexes has been investigated at room temperature using the cyclic voltammetry technique in DMFA. The Cu(II)/Cu(I) redox system was found to be consistent with the quasi-reversible diffusion-controlled process.
RESUMO
Guselkumab is a monoclonal antibody that selectively blocks the p19 subunit of interleukin 23 and has been approved for the treatment of moderate to severe psoriasis and active psoriatic arthritis in adult patients due to its efficacy in different clinical trials. Therefore, itis important to know the performance of guselkumab in this setting of patients in clinical practice given that a high percentage of them are not represented in these clinical trials. Our objective was to evaluate the effectiveness and tolerability of guselkumab in clinical practice in the first patients with psoriasis and psoriatic arthritis treated since the date of its approval for psoriasis in Spain, in joint dermatology-rheumatology clinics. A multicenter retrospective data collection was carried out, in which 14 hospitals participated, including a total of 90 patients with psoriatic arthritis confirmed by a rheumatologist. Data collection was recorded at baseline and at weeks 12, 24, and 52 for both the articular and cutaneous domains. Ninety PsA patients started treatment with guselkumab and therefore were included in this study. The vast majority had already failed to at least to one biologic therapyprior guselkumab prescription. The median age was 55 years, 61% were female and 46% had a BMI ≥ 30 kg/m2 . Sixty-nine percent suffered from peripheral arthritis, and in 34% an axial involvement was also detected; dactylitis or enthesitis was present in 24% and 29% of patients, respectively. Guselkumab was effective in controlling both articular and skin manifestations of PsA patients. Absolute PASI significantly decreased from 10.5 to 4.8, 1.9 and 1.3 at weeks 12, 24, and 52, respectively. In 29 out of 61 (48%) of cases, DAPSA was moderate or high, and patients showed a significant reduction in DAPSA at 12, 24, and 52 weeks of treatment (mean DAPSA values at baseline and follow up were 29, 20, 16, and 14, respectively). Patients with DAPSA in low activity or in remission at the time of initiation of guselkumab maintained response at the end of the study period. No new safety concerns were detected. Seventy-eight out of 90 patients (84.4%) persisted on treatment after 2 years follow-up. Our experience suggests that guselkumab isan effective drug for PsA and PsO patients in clinical practice with good tolerability and no additional safety signals, making it a new therapeutic alternative for the treatment of PsA and PsO patients.

The aim of the study was to assess the long-term effectiveness and safety of secukinumab in Spanish patients with moderate-to-severe psoriasis in a daily practice setting. Nationwide multicenter, observational, retrospective, non-interventional, single-cohort study including patients who initiated treatment with secukinumab in daily clinical practice conditions. Subjects were followed for a minimum of 3 months and a maximum of 24 months. Psoriasis Area Severity Index (PASI), Body Surface Area and Physician's Global Assessments were collected at baseline and months 3, 6, 12, 18 and 24 during treatment. Adverse events and reasons for secukinumab withdrawal were collected and classified for analyses. A total of 384 patients were enrolled in the study. Median PASI declined rapidly from 14.3 at baseline to 2.7 at month 3, 2.1 at month 12, and remained low (2.8) at month 24. Within the group of patients with PASI ≥10 at baseline (n = 278), 58.3%, 60.4% and 56.5% achieved a PASI90 response at months 3, 12 and 24, respectively. As for absolute PASI, 86.5%, 69.5%, 42.7% and 37% achieved PASI <5, < 3, < 1 and 0, respectively, at month 3. Secukinumab was more effective in biologic-naïve patients and in those with lower Body Mass Index. Secukinumab presented a good long-term safety profile. Secukinumab was effective and safe in a routine clinical setting, in a large cohort of patients with moderate-to-severe plaque psoriasis, in the short-, medium- and long-term (up to 24 months).

Psoriasis is a chronic dermatological disease with great impact on patients' quality of life (QoL). The main objective of this study was to assess the impact of secukinumab treatment on different patient-reported outcomes (PROs) during a long-term follow-up in Spanish patients with moderate-to-severe psoriasis under real-world conditions. Retrospective, observational, open-label, nationwide multicenter cohort study that included patients who initiated treatment with secukinumab in daily clinical practice conditions. PROs assessing disease impact and QoL included Dermatology Life Quality Index (DLQI), Patient's Global Psoriasis Assessment, Itch Numerical Rating Scale and EuroQoL Thermometer Visual Analogue Scale. Outcomes, including PROs and Psoriasis Area and Severity Index (PASI), were assessed at months 3, 6, 12, 18, and 24 during treatment. A total of 238 patients were enrolled in the study. Patients had a mean DLQI score of 14.9 at baseline; 78.3%, 73.7%, and 71.7% of them achieved a DLQI 0/1 response at months 6, 12, and 24, respectively. DLQI score was lower in the long term for naïve patients. A sharp decrease in mean DLQI was observed during the first 3 months, reaching a plateau that was maintained until the end of follow-up. Similar findings were observed for the rest of QoL assessments. There was a close association between improvement in QoL and skin clearance (PASI), which progressively increased during follow-up. In this study, secukinumab sustainably improved patient's QoL during a 24-month follow-up, with strongest effects in patients naïve to biological therapies and with a direct correlation with PASI improvement.

Plants host a diverse microbiome and differentially react to the fungal species living as endophytes or around their roots through emission of volatiles. Here, using divided Petri plates for Arabidopsis-T. atroviride co-cultivation, we show that fungal volatiles increase endogenous sugar levels in shoots, roots and root exudates, which improve Arabidopsis root growth and branching and strengthen the symbiosis. Tissue-specific expression of three sucrose phosphate synthase-encoding genes (AtSPS1F, AtSPS2F and AtSPS3F), and AtSUC2 and SWEET transporters revealed that the gene expression signatures differ from those of the fungal pathogens Fusarium oxysporum and Alternaria alternata and that AtSUC2 is largely repressed either by increasing carbon availability or by perception of the fungal volatile 6-pentyl-2H-pyran-2-one. Our data point to Trichoderma volatiles as chemical signatures for sugar biosynthesis and exudation and unveil specific modulation of a critical, long-distance sucrose transporter in the plant.

The effect of sex on systemic therapy for psoriasis has not been well studied. The aim of this study was to analyse a large multicentre Spanish cohort of 2,881 patients with psoriasis (58.3% males), followed from January 2008 to November 2018, to determine whether sex influences prescription, effectiveness of therapy, and the risk of adverse events. The results show that women are more likely than men to be prescribed biologics. There were no differences between men and women in effectiveness of therapy, measured in terms of drug survival. Women were more likely to develop adverse events, but the difference in risk was small and does not justify different management. Study limitations include residual confounding and the use of drug survival as a proxy for effectiveness.

The U.S. spends trillions annually on health care that affects only 16% of health outcomes, with 84% driven by social factors, behaviors, and the physical environment. Medical schools are focusing more on these social determinants of health. We describe an academic community engagement unit with unique methods for partnering with the surrounding community to improve its members' health. Annually, a Call for Ideas asked community members to identify important health problems and propose solutions. A panel of community members and academic researchers reviewed submitted ideas and selects those addressing significant issues, that are also feasible, can be accomplished in a year, and are potentially scalable. Financial, project development, and evaluation support is provided where needed. Three Calls for Ideas generated 268 ideas from 249 individuals: 35% focused on social and behavioral factors, 33% on health behaviors, 16% on health care, and 6% on the physical environment. Half were submitted by individuals and half by community service organizations. Twenty-four (9%) were selected for implementation; 19 have been successfully implemented while 5 are under development. People with lived experience can identify barriers to health in their communities and effective mitigating interventions. By seeking community leadership and mutual benefit, academicians can gain community members' trust and meet both community and academic needs by establishing true partnerships, recognizing power dynamics and structural biases, and using language and approaches that respect the importance and power of lived experiences in identifying approaches to enhancing community health.

Despite the promise of psychosocial interventions for adolescent Attention Deficit Hyperactivity Disorder (ADHD), there are no studies that examine their implementation in community mental health contexts. In this study, we evaluate the implementation of community-based Supporting Teens' Autonomy Daily (STAND), a parent-teen Motivational Interviewing + Behavior Therapy intervention for adolescents with ADHD. Adolescents with ADHD (N = 225), who were clients at four community mental health agencies, received treatment from 82 therapists. There was double randomization of adolescents and therapists to STAND or Usual Care (UC). Nearly all therapists randomized to STAND completed the training and regularly attended supervision, rating STAND as acceptable and lower burden than UC practices. In the STAND group, MI competence and implementation were lower than in university trials (benchmark range, 19.5% for reflection to question ratio to 83.1% for technical globals). MI integrity in the STAND group was significantly higher than UC across most MITI indices. Content fidelity was adequate in STAND's engagement and skills phases (76.4-85.0%), but not its planning phase (24.4%). Therapists commonly neglected weekly review of goals and home practice and deviated from manualized pace and sequencing of therapy tasks. Learning MI was more challenging for bilingual therapists and therapists with more years of experience. STAND was delivered with higher integrity in earlier sessions and office-based sessions. Discussion identifies future directions for exporting adolescent ADHD interventions to community settings. Patient outcome data for this trial is presented elsewhere.

The arts-and the arts and culture sector-offer fertile ground for achieving a culture of health in the United States. The arts and artists are agents of change and can help enable this vision and also address the most critical public health issues we are contending with, including COVID-19 and racism. The arts provide means for engaging dialogue, influencing behaviors, disrupting paradigms and fueling social movements. The arts uncover and illuminate issues. They engage us emotionally and intellectually. They challenge assumptions. They call out injustice. They drive collective action. They heal-making arts + public health collaboration very relevant in this historic moment. In this special Health Promotion Practice supplement on arts in public health, you'll find powerful examples and evidence of how cross-sector collaboration between public health and the arts can advance health promotion goals and impacts, and make health promotion programs not only more accessible to diverse populations but also more equitable and effective in addressing the upstream systems, policies, and structures that create health disparities. You will see how the arts can empower health communication, support health literacy, provide direct and measurable health benefits to individuals and communities, and support coping and resilience in response to COVID-19. This issue itself exemplifies cross-sector collaboration, as it was created through partnership between Health Promotion Practice, the Society for Public Health Education, ArtPlace America, and the University of Florida Center for Arts in Medicine, and presents voices from across the public health, arts, and community development sectors.

The goal of this study was to evaluate the comparative efficacy of 2 clinic-based psychosocial treatment modalities for adolescent attention deficit/hyperactivity disorder (ADHD) and identify characteristics that facilitate patient-modality matching. Culturally diverse adolescents with ADHD (N = 123) were randomized to 1 of 2 versions of a parent-teen psychosocial treatment for ADHD (Supporting Teens' Autonomy Daily [STAND]): (a) group parent and adolescent skills training or (b) dyadic skills training blended with motivational interviewing. Participants were assessed at baseline, posttreatment, and 6-month follow-up on ADHD symptom severity and functional treatment targets. Differences in therapy process and cost were documented. Modality differences in outcome were examined using linear mixed and general linear models. Each modality successfully engaged the proposed therapy processes. Dyadic and group STAND produced equivalent overall outcomes. However, the dyadic modality demonstrated superior efficacy when parents had elevated ADHD or depression symptoms or high conflict with the teen. Families with lower parent education level and higher parental depression showed lower overall attendance; married parents were more likely to attend dyadic STAND (vs. group). Naturalistic stimulant medication did not influence treatment outcome. At less than one third of the cost of dyadic treatment, group models may be an economical option for treating parents and adolescents with ADHD. Screening adolescents with ADHD for parental psychopathology and parent-teen conflict may allow clinics to match higher risk patients to more personalized approaches that can enhance efficacy.

Iron is an essential plant micronutrient. It is a component of numerous proteins and participates in cell redox reactions; iron deficiency results in a reduction in nutritional quality and crop yields. Volatiles from the rhizobacterium Arthrobacter agilis UMCV2 induce iron acquisition mechanisms in plants. However, it is not known whether microbial volatiles modulate other metabolic plant stress responses to reduce the negative effect of iron deficiency. Mass spectrometry has great potential to analyze metabolite alterations in plants exposed to biotic and abiotic factors. Direct liquid introduction-electrospray-mass spectrometry was used to study the metabolite profile in Medicago truncatula due to iron deficiency, and in response to microbial volatiles. The putatively identified compounds belonged to different classes, including pigments, terpenes, flavonoids, and brassinosteroids, which have been associated with defense responses against abiotic stress. Notably, the levels of these compounds increased in the presence of the rhizobacterium. In particular, the analysis of brassinolide by gas chromatography in tandem with mass spectrometry showed that the phytohormone increased ten times in plants grown under iron-deficient growth conditions and exposed to microbial volatiles. In this mass spectrometry-based study, we provide new evidence on the role of A. agilis UMCV2 in the modulation of certain compounds involved in stress tolerance in M. truncatula.

KEY MESSAGE: Our results show that Sorghum bicolor is able to recognize bacteria through its volatile compounds and differentially respond to beneficial or pathogens via eliciting nutritional or defense adaptive traits. Plants establish beneficial, harmful, or neutral relationships with bacteria. Plant growth promoting rhizobacteria (PGPR) emit volatile compounds (VCs), which may act as molecular cues influencing plant development, nutrition, and/or defense. In this study, we compared the effects of VCs produced by bacteria with different lifestyles, including Arthrobacter agilis UMCV2, Bacillus methylotrophicus M4-96, Sinorhizobium meliloti 1021, the plant pathogen Pseudomonas aeruginosa PAO1, and the commensal rhizobacterium Bacillus sp. L2-64, on S. bicolor. We show that VCs from all tested bacteria, except Bacillus sp. L2-64, increased biomass and chlorophyll content, and improved root architecture, but notheworthy A. agilis induced the release of attractant molecules, whereas P. aeruginosa activated the exudation of growth inhibitory compounds by roots. An analysis of the expression of iron-transporters SbIRT1, SbIRT2, SbYS1, and SbYS2 and genes related to plant defense pathways COI1 and PR-1 indicated that beneficial, pathogenic, and commensal bacteria could up-regulate iron transporters, whereas only beneficial and pathogenic species could induce a defense response. These results show how S. bicolor could recognize bacteria through their volatiles profiles and highlight that PGPR or pathogens can elicit nutritional or defensive traits in plants.

BACKGROUND: The chronicity status of breast cancer survivors suggests a growing need for cancer rehabilitation. Currently, the use of technology is a promising strategy for providing support, as reflected in the emergence of research interest in Web-based interventions in cancer survivorship. METHODS: A randomized controlled trial was conducted that included a total of 81 participants who had completed adjuvant therapy (except hormone treatment) for stage I to IIIA breast cancer. Participants were randomly assigned to an 8-week Internet-based, tailored exercise program (n = 40) or to a control group (n = 41).The instruments used at baseline, 8 weeks, and 6-month follow-up were the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30 and its breast cancer module, the Brief Pain Inventory, the handgrip dynamometer, the isometric abdominal test, the back dynamometer, the multiple sit-to-stand test, and the Piper Fatigue Scale. RESULTS: After the intervention, the telerehabilitation group had significantly improved scores for global health status, physical, role, cognitive functioning, and arm symptoms (all P < .01) as well as pain severity (P = .001) and pain interference (P = .045) compared with the control group. Significant improvements also were observed favoring the telerehabilitation group for affected and nonaffected side handgrip (both P = .006), abdominal, back and lower body strength (all P < .01), and total fatigue (P < .001). These findings were maintained after 6 months of follow-up, except for role functioning, pain severity, and nonaffected side handgrip. Analysis was based on an intention-to-treat principle. CONCLUSIONS: This program may improve adverse effects and maintain benefits in breast cancer survivors. The results of this study have encouraging implications for cancer care.

Plants interact with root microbes via chemical signaling, which modulates competence or symbiosis. Although several volatile organic compounds (VOCs) from fungi may affect plant growth and development, the signal transduction pathways mediating VOC sensing are not fully understood. 6-pentyl-2H-pyran-2-one (6-PP) is a major VOC biosynthesized by Trichoderma spp. which is probably involved in plant-fungus cross-kingdom signaling. Using microscopy and confocal imaging, the effects of 6-PP on root morphogenesis were found to be correlated with DR5:GFP, DR5:VENUS, H2B::GFP, PIN1::PIN1::GFP, PIN2::PIN2::GFP, PIN3::PIN3::GFP and PIN7::PIN7::GFP gene expression. A genetic screen for primary root growth resistance to 6-PP in wild-type seedlings and auxin- and ethylene-related mutants allowed identification of genes controlling root architectural responses to this metabolite. Trichoderma atroviride produced 6-PP, which promoted plant growth and regulated root architecture, inhibiting primary root growth and inducing lateral root formation. 6-PP modulated expression of PIN auxin-transport proteins in a specific and dose-dependent manner in primary roots. TIR1, AFB2 and AFB3 auxin receptors and ARF7 and ARF19 transcription factors influenced the lateral root response to 6-PP, whereas EIN2 modulated 6-PP sensing in primary roots. These results indicate that root responses to 6-PP involve components of auxin transport and signaling and the ethylene-response modulator EIN2.

PURPOSE: Fructose intake from added sugars correlates with the epidemic rise in metabolic syndrome and cardiovascular diseases. However, consumption of beverages containing fructose is allowed during gestation. Recently, we found that an intake of fructose (10 % wt/vol) throughout gestation produces impaired fetal leptin signaling and hepatic steatosis. Therefore, we have investigated whether fructose intake during pregnancy produces subsequent changes in the progeny, when adult. METHODS: Fed 261-day-old male and female descendants from fructose-fed, control or glucose-fed mothers were used. Plasma was used to analyze glucose, insulin, leptin, and adiponectin. Hepatic expression of proteins related to insulin signaling was determined. RESULTS: Fructose intake throughout pregnancy did not produce alterations in the body weight of the progeny. Adult male progeny of fructose-fed mothers had elevated levels of insulin without a parallel increase in phosphorylation of protein kinase B. However, they displayed an augmented serine phosphorylation of insulin receptor substrate-2, indicating reduced insulin signal transduction. In agreement, adiponectin levels, which have been positively related to insulin sensitivity, were lower in male descendants from fructose-fed mothers than in the other two groups. Furthermore, mRNA levels for insulin-responsive genes were not affected (phosphoenolpyruvate carboxykinase, glucose-6-phosphatase) or they were decreased (sterol response element-binding protein-1c) in the livers of male progeny from fructose-supplemented rats. On the contrary, adult female rats from fructose-fed mothers did not exhibit any of these disturbances. CONCLUSION: Maternal fructose, but not glucose, intake confined to the prenatal stage provokes impaired insulin signal transduction, hyperinsulinemia, and hypoadiponectinemia in adult male, but not female, progeny.

OBJECTIVES: To analyze the effect of weight on psychological and functional outcomes in multiple sclerosis (MS) patients, including self-perception, depression, functional level, fatigue, and self-rated health status. METHODS: One hundred and one (n = 101) patients with MS participated in this cross-sectional study. Outcomes were scores in the Beck Depression Inventory, NEO Five-Factor Inventory (NEOFFI), Functional Assessment of Multiple Sclerosis (FAMS), Fatigue Impact Scale, and Quality Short-Form Health Survey 36 (SF-36). Patients were classified as normal weight (18.5 < BMI < 24.9 kg/m(2)) or overweight (25.0 > BMI > 29.9 kg/m(2)). One-way analysis of covariance was conducted with gender, age, and years with disease as covariates. RESULTS: Depression levels were significantly higher in overweight versus normal-weight MS patients (F = 6.381; P = 0.013). NEOFFI scores were significantly higher in overweight versus normal-weight MS patients for extraversion (F = 6.331; P = 0.014), conscientiousness (F = 4.794; P = 0.034), and neuroticism (F = 5.422; P = 0.022) but not for openness (F = 2.174; P = 0.109) or agreeableness (F = 0.047; P = 0.829). The two groups did not significantly differ in fatigue (P > 00.5). Scores in general (F = 4.708; P = 0.032) and mental health (F = 4.583; P = 0.035) SF-36 domains were significantly lower in overweight versus normal-weight patients. Scores for FAMS domains of emotional well-being (F = 8.050; P = 0.006), general contentment (F = 7.967; P = 0.006), and family/social well-being (F = 7.662; P = 0.007) were significantly lower in overweight versus normal-weight patients. CONCLUSIONS: Overweight MS patients evidenced higher depression levels, lower functional capacity, and worse self-rated health status in comparison to normal-weight MS patients. These results suggest that weight control programs should be incorporated into the management of patients with MS.

OBJECTIVE: The aim of the present study was to report pressure pain sensitivity topographical maps of the frontal and dorsal parts of the shoulder region, and locate the pressure pain sensitive areas in breast cancer survivors compared with matched healthy control subjects. METHODS: Twenty-two breast cancer survivors (BCS) and 22 matched control subjects participated. A numeric pain rating scale of the neck-shoulder area and pressure pain thresholds (PPTs) was assessed bilaterally over 28 points in the frontal and dorsal neck-shoulder area. Topographical pain sensitivity maps of the upper trapezius, pectoral, and anterior deltoid areas were computed. RESULTS: A three-way analysis of variance was carried out to evaluate the differences in PPTs. The BCS reported spontaneous neck pain (mean ± SD 3.6 ± 2.8), pain in the affected shoulder (4.3 ± 2.7), and pain in the non-affected shoulder (0.9 ± 1.8). Additionally, the BCS exhibited bilaterally lower PPTs in all the measurement points as compared with the control subjects (P < 0.05). The PPTs were lower at the superior part of the trapezius muscle (P < 0.001), the musculotendinous insertion, the anterior part of the deltoid muscle (P < 0.001), and the tendon of the pectoral muscle (P < 0.001) as compared with the control subjects. CONCLUSIONS: The results suggest the sensitization processes in the BCS and give preliminary evidence to most sensitive areas in the superior part of the upper trapezius and musculotendinous insertion of the pectoral muscle.

BACKGROUND: Mobile learning (m-learning) has becoming very popular in education due to the rapidly advancing technology in our society. The potentials of the mobile applications should be used to enhance the education process. Few mobile applications have been designed to complement the study of physical therapy skills for physiotherapy students. The aim of this study was to investigate whether a mobile application, as a supplement to traditional learning, is useful for physiotherapy students in the acquisition of palpation and ultrasound skills in the shoulder area. METHODS: Forty-nine students participated in this single-blinded, randomized controlled study. They were randomly distributed into two groups: experimental, with free access to the mobile application; and control, with access to traditional learning materials on the topic. Objective structured clinical evaluation (OSCE) and multiple-choice questionnaire (MCQ) were used to assess the educational intervention. Then, we also assessed the time taken to get a reliable ultrasound image and to localize a specific shoulder structure by palpation. RESULTS: There was no significant intergroup difference in the acquisition of theoretical knowledge (p = .089). Scores were significantly higher in the experimental group than in the control group for the majority items in the ultrasound assessment; positioning of patient (p < .001), positioning of ultrasound probe (p = 0.007), handling of ultrasound probe (p = .013) and global OSCE (p < .001) and skills in palpation of the shoulder; position of patient (p = .009), direction of palpation contact (p = .021) and global OSCE (p = .034). There were no significant differences in the time required to perform the examination between groups in ultrasound (p = .944) and palpation (p = .393). The results from the post-program survey assessing the global satisfaction with the mobile application were high (8.200 ± .767), on an 11 numeric point rating scale. CONCLUSION: These results suggest the effectiveness of an m-learning program as a complement to traditional education for developing skills in ultrasound and palpation of the shoulder region in undergraduate physiotherapy students.
