Experiences of people with Long Covid with a digital physiotherapy intervention: A qualitative study.

PURPOSE: Long Covid syndrome is a multiorgan condition with multiple sequelae affecting quality of life, capacity to work and daily activities. The advantages that new technologies can offer are presented as an opportunity in the current healthcare framework. OBJECTIVE: This research aimed to explore people with Long Covid's experiences with a digital physiotherapy practice intervention, during four weeks. METHODS: Qualitative semistructured interviews were conducted by video call. Thirty-two Long Covid participants were invited to join an in-depth interview once the intervention was completed. Participants were queried on their intervention experiences and perceptions, as well as any lifestyle changes made, as a result of receiving digital physiotherapy practice. The interviews were transcribed and analysed using inductive qualitative content analysis. RESULTS: In-depth qualitative analysis has revealed four themes that reflect participants' perceptions of digital physiotherapy intervention. The helpfulness of the exercises, interaction with the physiotherapist, the domestic use of technology and the future of digital health practice were the topics highlighted by Long Covid participants. Some improvements have been suggested including video sounds and the need to introduce face-to-face sessions. Participants stated that interventions were helpful and superior to printed exercise sheets, mobile phone apps and usual care received. This intervention did not present major barriers, highlighting the importance of personalized care and continuity in the provision of health services. CONCLUSION: The digital physiotherapy practice is perceived by people with Long Covid as an appropriate method for the care of their health needs. Participants stated the need for this type of intervention in the public health system, where it would eliminate waiting lists, facilitate accessibility and improve existing care. PATIENT AND PUBLIC CONTRIBUTION: Participants contributed to the interpretation of the data acquired in the interview. CLINICAL TRIAL REGISTRATION: Trial registration NCT04742946.

Development and validation of an analytical methodology based on solvent microextraction and UHPLC-MS/MS for determining bisphenols in honeys from different botanical origins.

A new analytical methodology was proposed to determine fourteen bisphenols in honeys from different botanical origins using ultra-high performance liquid chromatography-tandem mass spectrometry. A fast, efficient, environmentally-friendly and simple sample treatment (recoveries between 81% and 116%; matrix effect <20% for all studied compounds except for bisphenol E, F and S) was proposed, which involved a solvent microextraction with acetone and a small volume/amount of 1-hexanol. Chromatographic analysis (< 15 min) was performed in a Kinetex EVO C18 column under gradient elution mode. The method was validated in terms of selectivity, limits of detection (0.2-1.5 µg/kg) and quantification (0.5-4.7 µg/kg), linearity, matrix effect, trueness, and precision (relative standard deviation <17%). Finally, thirty honey samples were analyzed, revealing the presence of residues of nine bisphenols in some of them. However, quantification was possible only in two cases for bisphenol A, with a concentration of approximately 13 µg/kg.

CFTR pathogenic variants spectrum in a cohort of Mexican patients with cystic fibrosis.

Background: Molecular diagnosis of cystic fibrosis (CF) is challenging in Mexico due to the population's high genetic heterogeneity. To date, 46 pathogenic variants (PVs) have been reported, yielding a detection rate of 77%. We updated the spectrum and frequency of PVs responsible for this disease in mexican patients. Methods: We extracted genomic DNA from peripheral blood lymphocytes obtained from 297 CF patients and their parents. First, we analyzed the five most frequent PVs in the Mexican population using PCR-mediated site-directed mutagenesis. In patients with at least one identified allele, CFTR sequencing was performed using next-generation sequencing tools and multiplex ligation-dependent probe amplification. For variants not previously classified as pathogenic, we used a combination of in silico prediction, CFTR modeling, and clinical characteristics to determine a genotype-phenotype correlation. Results: We identified 95 PVs, increasing the detection rate to 87.04%. The most frequent variants were p.(PheF508del) (42.7%), followed by p.(Gly542*) (5.6%), p.(Ser945Leu) (2.9%), p.(Trp1204*) and p.(Ser549Asn) (2.5%), and CFTRdel25-26 and p.(Asn386Ilefs*3) (2.3%). The remaining variants had frequencies of <2.0%, and some were exclusive to one family. We identified 10 novel PVs localized in different exons (frequency range: 0.1-0.8%), all of which produced structural changes, deletions, or duplications in different domains of the protein, resulting in dysfunctional ion flow. The use of different in silico software and American College of Medical Genetics and Genomics (ACMG) and the Association for Molecular Pathology (AMP) criteria allowed us to assume that all of these PVs were pathogenic, causing a severe phenotype. Conclusions: In a highly heterogeneous population, combinations of different tools are needed to identify the variants responsible for CF and enable the establishment of appropriate strategies for CF diagnosis, prevention, and treatment.

Assessment of risk-adjusted mortality ratio (RAMR) in bloodstream infections using all-patient refined diagnosis-related groups (APR-DRGs).

OBJECTIVES: To calculate a risk-adjusted mortality ratio (RAMR) for bloodstream infections (BSIs) using all-patient refined diagnosis-related groups (APR-DRGs) and compare it with the crude mortality rate (CMR). METHODS: Retrospective observational study of prevalent BSI at our institution from January 2019 to December 2022. In-hospital mortality was adjusted with a binary logistic regression model adjusting for sex, age, admission type and mortality risk for the hospitalization episode according to the four severity levels of APR DRGs. The RAMR was calculated as the ratio of observed to expected in-hospital mortality, and the CMR was calculated as the proportion of deaths among all bacteraemia episodes. RESULTS: Of 2939 BSIs, 2541 were included: Escherichia coli (n = 1310), Klebsiella pneumoniae (n = 428), Pseudomonas aeruginosa (n = 209), Staphylococcus aureus (n = 498) and candidaemia (n = 96). A total of 436 (17.2%) patients died during hospitalization and 279 died within the first 14 days after the onset of BSI. Throughout the period, all BSI cases had a mortality rate above the expected adjusted mortality (RAMR value greater than 1), except for Escherichia coli (1.03; 95% CI 0.86-1.21). The highest overall RAMR values were observed for P. aeruginosa, Candida and S. aureus with 2.06 (95% CI 1.57-2.62), 1.99 (95% CI 1.3-2.81) and 1.8 (95% CI 1.47-2.16), respectively. The temporal evolution of CMR may differ from RAMR, especially in E. coli, where it was reversed. CONCLUSIONS: RAMR showed higher than expected mortality for all BSIs studied except E. coli and provides complementary to and more clinically comprehensive information than CMR, the currently recommended antibiotic stewardship programme mortality indicator.

Association of PADI2 and PADI4 polymorphisms in COVID-19 host severity and non-survival.

Background: Enzymes of the peptidylarginine deiminase family (PADs) play a relevant role in the pathogenesis of COVID-19. However, the association of single nucleotide polymorphisms (SNPs) in their genes with COVID-19 severity and death is unknown. Methodology: We included 1045 patients who were diagnosed with COVID-19 between October 2020 and December 2021. All subjects were genotyped for PADI2 (rs1005753 and rs2235926) and PADI4 (rs11203366, rs11203367, and rs874881) SNPs by TaqMan assays and their associations with disease severity, death, and inflammatory biomarkers were evaluated. Results: 291 patients presented had severe COVID-19 according to PaO2/FiO2, and 393 had a non-survival outcome. Carriers of the rs1005753 G/G genotype in the PADI2 gene presented susceptibility for severe COVID-19, while the heterozygous carriers in rs11203366, rs11203367, and rs874881 of the PADI4 gene showed risk of death. The GTACC haplotype in PADI2-PADI4 was associated with susceptibility to severe COVID-19, while the GCACC haplotype was a protective factor. The GCGTG haplotype was associated with severe COVID-19 but as a protective haplotype for death. Finally, the GTACC haplotype was associated with platelet-to-lymphocyte ratio (PLR), the GCACC haplotype with neutrophil-to-hemoglobin and lymphocyte and the GCGTG haplotype as a protective factor for the elevation of procalcitonin, D-dimer, CRP, LCRP, NHL, SII, NLR, and PLR. Conclusions: Our results suggest that the haplotypic combination of GTACC and some individual genotypes of PADI2 and PADI4 contribute to the subjects' susceptibility for severity and death by COVID-19.

Performance of adenosine deaminase in synovial fluid for the diagnosis of tuberculous arthritis: A systematic review and meta-analysis.

OBJECTIVES: Adenosine deaminase (ADA) activity has shown good performance in diagnosing pleural, peritoneal, and meningeal tuberculosis. This meta-analysis aimed to evaluate the performance of measuring ADA activity in synovial fluid for the early diagnosis of joint tuberculosis. METHODS: We searched published information in MEDLINE, Embase, Cochrane Library, Web of Science, and MedRxiv databases, as well as unpublished information in the American College of Rheumatology and European League Against Rheumatism for conference abstracts (2012-2021). We also scanned the reference lists of articles. Two reviewers independently applied the criteria for selection, assessed quality, and extracted data (PROSPERO number CRD42021284472). RESULTS: Seven independent studies (N=305 subjects) that compared ADA activity in synovial fluid with a composite reference diagnostic method for tuberculosis were included. Overall, the risk of bias was judged low. Studies were classified as high quality (n=3; 148 subjects) and low quality (n=4; 157 subjects). Pooled sensitivity and specificity of ADA activity was 94% (95% confidence interval [CI], 0.89-98; I2=23%) and 88% (95% CI, 83-92; I2=83%), respectively. The random-effects model for pooled diagnostic Odds ratio was 67.1 (95%CI, 20.3-222.2; I2=30%). The receiver operating characteristic curve area was 0.96 (95% CI, 0.92-0.99). Meta-regression did not identify the quality of the study, country of publication, or the type of assay as a source of heterogeneity. CONCLUSIONS: Measuring ADA activity in synovial fluid demonstrates good performance for the early diagnosis of joint tuberculosis.

Regional differences in infective endocarditis epidemiology and outcomes in Spain. A contemporary population-based study.

INTRODUCTION AND OBJECTIVES: Our aim was to describe the contemporary epidemiological profile of infective endocarditis (IE) in Spain, and to evaluate variations in IE incidence, characteristics, and outcomes among the different Spanish regions (autonomous communities [AC]). METHODS: We conducted a retrospective, population-based study, using data obtained from national in-patient hospital activity of all patients discharged with a diagnosis of IE from hospitals included in the Spanish National Health System, from January 2016 to December 2019. Differences in the IE profile between the 17 Spanish AC were analyzed. RESULTS: A total of 9008 hospitalization episodes were identified during the study period. Standardized incidence of IE was 5.77 (95%CI, 5.12-6.41) cases per 100 000 population. Regarding predisposing conditions, 26.8% of episodes occurred in prosthetic valve carriers, 36.8% had some kind of valve heart disease, and 10.6% had a cardiac implantable electronic device. Significant differences were found between AC in terms of incidence, predisposing conditions, and microbiological profile. Cardiac surgery was performed in 19.3% of episodes in the total cohort, and in 33.4% of the episodes treated in high-volume referral centers, with wide variations among AC. Overall in-hospital mortality was 27.2%. Risk-adjusted mortality rates also varied significantly among regions. CONCLUSIONS: We found wide heterogeneity among Spanish AC in terms of incidence rates and the clinical and microbiological characteristics of IE episodes. The proportion of patients undergoing surgery was low and in-hospital mortality rates were high, with wide differences among regions. The development of regional networks with referral centers for IE could facilitate early surgery and improve outcomes.

Sex differences in population versus in-hospital use of aortic valve replacement procedures in Spain.

BACKGROUND AND AIMS: It is not well known if sex differences in the use and results of aortic valve replacement (AVR) are changing. The aim of the study is to assess the time trends in the differences by sex in the utilisation of AVR procedures in hospitals and in the community. METHODS: Retrospective observational analysis using data from the Spanish National Hospitalizations Administrative Database. All hospitalisations between 2016 and 2021 with a main diagnosis of aortic stenosis (ICD-10 codes: I35.0 and I35.2) were included. Time trends in hospitalisation, AVRs and hospital outcomes were analysed. Crude utilisation and population-standardised rates were calculated. RESULTS: During the study period, 64 384 hospitalisations in 55 983 patients (55.5% men) with 36 915 (65,9%) AVR were recorded. Of these, 15 563 (42.2%) were transcatheter and 21 432 (58.0%) surgical. At hospital level, transcatheter procedures were more frequently performed in women (32.3% vs 24.2%, p < 0.001) and surgical in men (42.9% vs. 32.5%, p < 0.001) but at the population level, surgical and transcatheter aortic valve replacements were used more frequently in men (12.6 surgical and 8.0 transcatheter per 100 000 population) vs women (6.4 and 5.8, respectively; p < 0.001 for both comparisons). Transcatheter procedures shifted from 17.3% in 2016 to 38.0% in 2021, overtaking surgical procedures in 2018 for women and 2021 for men. CONCLUSIONS: TAVR has displaced SAVR as the most frequent AVR procedure in Spain by 2020. This occurred earlier in women, who despite the greater weight of their age group in the older population, receive fewer AVRs, both SAVR and TAVR.

Digital physiotherapy is a satisfactory and effective method to improve the quality of life in Long COVID patients.

Objective: This research aimed to explore Long COVID patient's quality of life, satisfaction and perception with an individualized and customizable digital physiotherapy intervention during a 4-week period. Methods: A pre-post clinical trial was conducted with 32 Long COVID patients. Quality of life was assessed using the 12-Item Short Form Survey and the European Quality of Life-5 Dimensions questionnaire (EuroQol-5D), while satisfaction and perception were measured using the Telemedicine Satisfaction Questionnaire. Optional open-ended questions were added as qualitative approach. A mixed design method was conducted. Results: After intervention, a statistically significant improvement (p < 0.05) was observed in quality of life. The SF-12 questionnaire showed an increase of 4.04 points in the physical component and 6.55 points in the mental component with a small/medium effect size. The EuroQoL-5D questionnaire demonstrated a medium effect size with an increase of 0.87 points. Patient perception indicated high rates of satisfaction and values above the minimal clinically important difference. The qualitative approach revealed several interesting findings. Conclusion: Participants found the digital intervention satisfactory and effective in improving their quality of life. Suggestions for improvement, such as the inclusion of face-to-face sessions, a chat for immediate contact, sound in breath exercises in the digital program, longer duration and continuity of intervention, were mentioned. Larger sample studies and in-deep qualitative methodologies are needed to draw extrapolable conclusions. Trial registration: NCT04742946.

Free amino acid profile in Mimosa scabrella honeydew honey from Brazil and chemometric analysis for geographical discrimination.

In this study, twenty free amino acids (FAA) were investigated in samples of bracatinga (Mimosa scabrella) honeydew honey (BHH) from Santa Catarina (n = 15) and Paraná (n = 13) states (Brazil), followed by chemometric analysis for geographic discrimination. The FAA determination was performed by gas chromatography-mass spectrometry (GC-MS) after using a commercial EZ:faast™ kits for GC. Eight FAA were determined, being proline, asparagine, aspartic and glutamic acids found in all BHH, with significant differences (p < 0.05). In addition, with the exception of proline, the others FAA (asparagine, aspartic and glutamic) normally showed higher concentrations in samples from Santa Catarina state, being that in these samples it was also observed higher FAA sums (963.41 to 2034.73 mg kg-1) when compared to samples from Paraná state. The variability in the results did not show a clear profile of similarity when the heatmap and hierarchical grouping were correlated with the geographic origin and the concentration of eight determined FAA. However, principal component analysis (PCA) demonstrated that serine, asparagine, glutamic acid, and tryptophan were responsible for the geographic discrimination among samples from Santa Catarina and Paraná states, since they were the dominant variables (r > 0.72) in the PCA. Therefore, these results could be useful for the characterization and authentication of BHH based on their FAA composition and geographic origin.

Gender differences in clinical features and outcomes of patients over 75 years presenting with acute heart failure. Results of a nationwide study (2016-2019).

BACKGROUND: Heart failure (HF) is a major health problem in Western countries, and a leading cause of hospitalizations and death. There is a scarcity of data on the influence of sex on HF outcomes in elderly patients. The aim of the present study was to analyze differences between men and women in clinical characteristics, in-hospital mortality, 30-day HF readmission rates, cardiovascular mortality and HF readmission rates at 1 year after discharge in patients older than 75 years hospitalized for HF in Spain. METHODS: Retrospective analysis of patients discharged with a main diagnosis of HF from all Spanish public hospitals between 2016 and 2019. Patients aged 75 years or older were selected, and a comparison was made between male and female patients. RESULTS: From 2016 to 2019, a total of 354,786 episodes of HF in this age subgroup were identified, 59.2% being women. The overall mean age was 85.2 ± 5.4 years, being higher in women (85.9 ± 5.5 vs. 84.2 ± 5.3 years, p < 0.001). Risk-adjusted in-hospital mortality was lower in women (odds ratio [OR]: 0.96, 95% confidence interval [CI]: 0.92-0.97; p < 0.001). Female sex also showed a protective effect for 30-day readmissions, with an OR of 1.06 (95% CI: 1.04-1.09; p < 0.001). One-year cardiovascular mortality (24.1% vs. 25.0%; p < 0.001) and one-year HF readmission rates (30.8% vs. 31.6%; p = 0.001) were lower in women. CONCLUSIONS: Almost 60% of hospital admissions for HF in people aged 75 years or older between 2016 and 2019 in Spain were female patients. Female sex seems to play a protective role on in-hospital mortality and the rate of admissions and mortality at 1 year after discharge.

Clinical profile, management and outcomes of patients with cardiogenic shock undergoing transfer between centers in Spain.

INTRODUCTION AND OBJECTIVES: The aim of this study was to analyze the clinical profile, management, and prognosis of ST segment elevation myocardial infarction-related cardiogenic shock (STEMI-CS) requiring interhospital transfer, as well as the prognostic impact of structural variables of the treating centers in this setting. METHODS: This study included patients with STEMI-CS treated at revascularization-capable centers from 2016 to 2020. The patients were divided into the following groups: group A: patients attended throughout their admission at hospitals with interventional cardiology without cardiac surgery; group B: patients treated at hospitals with interventional cardiology and cardiac surgery; and group C: patients transferred to centers with interventional cardiology and cardiac surgery. We analyzed the association between the volume of STEMI-CS cases treated, the availability of cardiac intensive care units (CICU), and heart transplant with hospital mortality. RESULTS: A total of 4189 episodes were included: 1389 (33.2%) from group A, 2627 from group B (62.7%), and 173 from group C (4.1%). Transferred patients were younger, had a higher cardiovascular risk, and more commonly underwent revascularization, mechanical circulatory support, and heart transplant during hospitalization (P<.001). The crude mortality rate was lower in transferred patients (46.2% vs 60.3% in group A and 54.4% in group B, (P<.001)). Lower mortality was associated with a higher volume of care and CICU availability (OR, 0.75, P=.009; and 0.80, P=.047). CONCLUSIONS: The proportion of transfers in patients with STEMI-CS in our setting is low. Transferred patients were younger and underwent more invasive procedures. Mortality was lower among patients transferred to centers with a higher volume of STEMI-CS cases and CICU.

Influence of threshold selection and image sequence in in-vivo segmentation of enlarged perivascular spaces.

BACKGROUND: Growing interest surrounds perivascular spaces (PVS) as a clinical biomarker of brain dysfunction given their association with cerebrovascular risk factors and disease. Neuroimaging techniques allowing quick and reliable quantification are being developed, but, in practice, they require optimisation as their limits of validity are usually unspecified. NEW METHOD: We evaluate modifications and alternatives to a state-of-the-art (SOTA) PVS segmentation method that uses a vesselness filter to enhance PVS discrimination, followed by thresholding of its response, applied to brain magnetic resonance images (MRI) from patients with sporadic small vessel disease acquired at 3 T. RESULTS: The method is robust against inter-observer differences in threshold selection, but separate thresholds for each region of interest (i.e., basal ganglia, centrum semiovale, and midbrain) are required. Noise needs to be assessed prior to selecting these thresholds, as effect of noise and imaging artefacts can be mitigated with a careful optimisation of these thresholds. PVS segmentation from T1-weighted images alone, misses small PVS, therefore, underestimates PVS count, may overestimate individual PVS volume especially in the basal ganglia, and is susceptible to the inclusion of calcified vessels and mineral deposits. Visual analyses indicated the incomplete and fragmented detection of long and thin PVS as the primary cause of errors, with the Frangi filter coping better than the Jerman filter. COMPARISON WITH EXISTING METHODS: Limits of validity to a SOTA PVS segmentation method applied to 3 T MRI with confounding pathology are given. CONCLUSIONS: Evidence presented reinforces the STRIVE-2 recommendation of using T2-weighted images for PVS assessment wherever possible. The Frangi filter is recommended for PVS segmentation from MRI, offering robust output against variations in threshold selection and pathology presentation.

Weekend and holiday admissions for decompensated heart failure and in-hospital mortality. A cumulative effect of "nonworking" days?

INTRODUCTION AND OBJECTIVES: The aim of this study was to analyze whether nonelective admissions in patients with heart failure (HF) on nonworking days (NWD) are associated with higher in-hospital mortality. METHODS: We conducted a retrospective (2018-2019) observational study of episodes of nonelective admissions in patients aged 18 years and older discharged with a principal diagnosis of HF in acute general hospitals of the Spanish National Health System. NWD at admission were defined as Fridays after 14:00hours, Saturdays, Sundays, and national and regional holidays. In-hospital mortality was analyzed with logistic regression models. The length of NWD was considered as an independent continuous variable. Propensity score matching was used as a sensitivity analysis. RESULTS: We selected 235 281 episodes of nonelective HF admissions. When the NWD periods were included in the in-hospital mortality model, the increases in in-hospital mortality compared with weekday admission were as follows: 1 NWD day (OR, 1.11; 95%CI, 1.07-1.16); 2 days (OR, 1.13; 95%CI, 1.09-1.17); 3 (OR, 1.16; 95%CI, 1.05-1.27); and ≥4 days (OR, 1.20; 95%CI, 1.09-1.32). There was a statistically significant association between a linear increase in NWD and higher risk-adjusted in-hospital mortality (chi-square trend P=.0002). After propensity score matching, patients with HF admitted on NWD had higher in-hospital mortality than those admitted on weekdays (OR, 1.11; average treatment effect, 12.2% vs 11.1%; P<.001). CONCLUSIONS: We found an association between admissions for decompensated HF on an NWD and higher in-hospital mortality. The excess mortality is likely not explained by differences in severity. In this study, the "weekend effect" tended to increase as the NWD period became longer.

Contamination of Honeybee (Apis mellifera L.) Royal Jelly by Pesticides and Sample Preparation Methods for Its Determination: A Critical Appraisal.

Pesticides can easily enter the food chain, harming bee populations and ecosystems. Exposure of beehive products to various contaminants has been identified as one of the factors contributing to the decline in bee populations, and multiple food alerts have been reported. Despite this fact, royal jelly, a valuable bee product with nutritional and functional properties, has received less attention in this context. Pesticide residues of different chemical class can contaminate royal jelly when foraging bees collect pollen or nectar from pesticide-treated flowers, or in some cases, due to its frequent and inappropriate use in the treatment of mites in beehives. To monitor this issue and also make it more reliable, it is crucial to develop effective sample preparation methods for extracting pesticides from royal jelly for subsequent analysis. In this context, this review provides information about sample preparation methods (solid-phase extraction, solvent extraction, and QuEChERS-quick, easy, cheap, effective, rugged and safe) and analytical methods that have been validated or improved to extract and analyze pesticides, respectively, in royal jelly samples of different origins. Finally, future perspectives are discussed. With this background, we aim to provide data that can guide future research related to this topic.

Telerehabilitation and telemonitoring interventions programs used to improving quality of life in people with cystic fibrosis: A systematic review.

Background: Cystic fibrosis causes mucus to build up in the lungs, digestive tract, and other areas. It is the most common chronic lung disease in children and young adults. It requires daily medical care. Before the COVID-19 pandemic, telerehabilitation and telehealth were used, but it was after this that there was a boom in these types of assistance in order to continue caring for cystic fibrosis patients. Objective: The objective is to evaluate the effect of telemedicine programs in people with cystic fibrosis. Methods: For the search, the PubMed, Scopus, Web of Science, PEDro, Cochrane, and CINAHL databases were used. Randomized controlled trials, pilot studies, and clinical trials have been included. The exclusion criteria have considered that the population did not have another active disease or that telemedicine was not used as the main intervention. This study follows the PRISMA statement and has been registered in the PROSPERO database (CRD42021257647). Results: A total of 11 articles have been included in the systematic review. No improvements have been found in quality of life, forced expiratory volume, and forced vital capacity. Good results have been found in increasing physical activity and early detection of exacerbations. Adherence and satisfaction are very positive and promising. Conclusions: Despite not obtaining significant improvements in some of the variables, it should be noted that the adherence and satisfaction of both patients and workers reinforce the use of this type of care. Future studies are recommended in which to continue investigating this topic.

Virtual reality to improve low-back pain and pelvic pain during pregnancy: a pilot RCT for a multicenter randomized controlled trial.

A significant proportion of women experience low back and pelvic pain during and after pregnancy, which can negatively impact their daily lives. Various factors are attributed to these complaints, and many affected women do not receive adequate healthcare. However, there is evidence to support the use of different physiotherapeutic interventions to alleviate these conditions. Virtual reality is a promising complementary treatment to physiotherapy, particularly in improving pain perception and avoidance. The primary objective of this study is to evaluate the efficacy of a four-week program combining VR and physiotherapy compared to standard physiotherapy in pregnant women with low back and pelvic pain, in terms of improving pain avoidance, intensity, disability, and functional level. The study also aims to investigate patient satisfaction with the VR intervention. This research will be conducted through a multi-center randomized controlled clinical trial involving pregnant patients residing in the provinces of Seville and Malaga with a diagnosis of low back and pelvic pain during pregnancy. The alternative hypothesis is that the implementation of a Virtual Reality program in combination with standard physiotherapy will result in better clinical outcomes compared to the current standard intervention, which could lead to the development of new policies and interventions for these pathologies and their consequences. Clinical trial registration: clinicaltrials.gov, identifier NCT05571358.
