Seguimiento a muy largo plazo tras implante de stent en la coartación de aorta / Very long-term follow-up after aortic stenting for coarctation of the aorta

Introducción y objetivos: El implante de stent es el tratamiento de elección en niños mayores y adultos con coartación aórtica (CoA). El objetivo fue determinar la incidencia de eventos tardíos después del tratamiento con stent. Métodos: Se analizó una cohorte de pacientes con CoA tratados en el centro entre 1993 y 2018 a los que se siguió periódicamente, incluyendo evaluación mediante tomografía computarizada (TC) y fluoroscopia. Resultados: Se incluyó a 167 pacientes con TC y fluoroscopia: 83 (49,7%) ≤ 12 años y 46 (28%) mujeres. El tiempo medio de seguimiento clínico fue de 17±8 años (rango 4-30) y de 11±7 años hasta la TC/fluoroscopia. Se detectó aneurisma en un 13% y se asoció al stent PALMAZ (OR=3,09; IC95%, 1,11-9,49; p=0,036) y a la longitud del stent (OR=0,94; IC95%, 0,89-0,99; p=0,039). La fractura del stent fue frecuente (34%) pero no asociada a la presencia de aneurisma. Se asoció con edad joven (OR=3,57; IC95%, 1,54-8,33; p=0,003), sexo masculino (OR=4,00; IC95%, 1,51-12,50; p=0,008) e inversamente con el stent PALMAZ (OR=0,29; IC95%, 0,12-0,67; p=0,005). La reintervención fue menor en adultos (10%), principalmente por aneurismas. Los pacientes que recibieron tratamiento cuando tenían 12 años o menos presentaron tasas de reintervención más altas (43%) debido al crecimiento somático. Conclusiones: Se observó una incidencia notable de eventos tardíos a largo plazo en pacientes con CoA tratados mediante stent. La reintervención fue más frecuente en pacientes tratados a edades más jóvenes. Parece aconsejable una vigilancia periódica mediante pruebas de imagen. (AU)

Introduction and objectives: Stent implantation is the preferred treatment in older children and adults with aortic coarctation (CoA). We aimed to determine the incidence of very late events after CoA stenting. Methods: We analyzed a cohort of CoA patients who underwent stent implantation at our center between 1993 and 2018. Patients were periodically followed up in outpatient clinics, including computed tomography (CT) and fluoroscopy assessment. Results: A total of 167 patients with CT and fluoroscopy data were included: 83 (49.7%) were aged ≤ 12 years and 46 (28%) were female. The mean clinical follow-up time was 17±8 (range 4-30) years and the mean time to CT/fluoroscopy was 11±7 years. Aortic aneurysm was present in 13% and was associated with the PALMAZ stent (OR, 3.09; 95%CI, 1.11-9.49; P=.036) and the stented length (OR, 0.94; 95%CI, 0.89-0.99; P=.039). Stent fracture was frequent (34%), but was not related to the presence of aneurysm. Stent fracture was associated with young age (OR, 3.57; 95%CI, 1.54-8.33; P=.003), male sex (OR, 4.00; 95%CI, 1.51-12.5, P=.008) and inversely with the PALMAZ stent (OR, 0.29; 95%CI, 0.12-0.67, P=.005). Reintervention was lower in adults (10%), mainly related to aneurysms. Those treated when aged ≤ 12 years had higher reintervention rates (43%) due to recoarctation somatic growth. Conclusions: This long-term follow-up study of CoA patients treated with stenting revealed a significant incidence of late events. Reintervention rates were higher in patients treated at younger ages. Periodic imaging surveillance appears to be advisable. (AU)

Predictive factors for decompensating events in patients with cirrhosis with primary biliary cholangitis under different lines of therapy.

BACKGROUND AND AIMS: The landscape in primary biliary cholangitis (PBC) has changed with the advent of second-line treatments. However, the use of obeticholic acid (OCA) and fibrates in PBC-related cirrhosis is challenging. We assessed the impact of receiving a second-line therapy as a risk factor for decompensated cirrhosis in a real-world population with cirrhosis and PBC, and identify the predictive factors for decompensated cirrhosis in these patients. APPROACH AND RESULTS: Multicenter study enrolling 388 patients with PBC-cirrhosis from the Spanish ColHai registry. Biopsy (20%), ultrasound (59%), or transient elastography (21%) defined cirrhosis, and the presence of varices and splenomegaly defined clinically significant portal hypertension (CSPH). Paris-II and PBC OCA international study of efficacy criteria determined the response to ursodeoxycholic acid (UDCA), fibrates (n=93), and OCA (n=104). The incidence of decompensated cirrhosis decreased for UDCA versus OCA or fibrates in the real-world population, but they were similar considering the propensity score-matched cohort (UDCA 3.77 vs. second-line therapy 4.5 100 persons-year, respectively), as patients on second-line therapy exhibited advanced liver disease. Consequently, GGT, albumin, platelets, clinically significant portal hypertension, and UDCA response were associated with a decompensating event. OCA response (achieved in 52% of patients) was associated with bilirubin (OR 0.21 [95% CI: 0.06-0.73]) and AST (OR 0.97 [95% CI: 0.95-0.99]), while fibrate response (achieved in 55% of patients) with AST [OR 0.96 (95% CI: 0.95-0.98]). In patients treated with OCA, drug response (sHR 0.23 [95% CI: 0.08-0.64]), diabetes (sHR 5.62 [95% CI: 2.02-15.68]), albumin (sHR 0.34 [95% CI: 0.13-0.89]), and platelets (sHR 0.99 [95% CI: 0.98-1.00]) were related to decompensation. In patients treated with fibrate, drug response (sHR 0.36 (95% CI: 0.14-0.95]), albumin (sHR 0.36 (95% CI: 0.16-0.81]), and clinically significant portal hypertension (sHR 3.70 (95% CI: 1.17-11.70]) were associated with decompensated cirrhosis. CONCLUSIONS: Advanced PBC, rather than OCA and fibrates, was found to be associated with decompensating events. Therefore, biochemical and clinical variables should be considered when making decisions about the management of these drugs. Moreover, a positive response to OCA and fibrates reduced the risk of decompensation.

A randomized controlled trial on the effectiveness of mirror therapy in improving strength, range of movement and muscle activity, in people with carpal tunnel syndrome.

BACKGROUND: There is little information on the potential effects of mirror therapy (MT) on motor recovery in individuals with Carpal Tunnel Syndrome (CTS). PURPOSE: To compare the effectiveness of a MT protocol versus a therapeutic exercise (TE) protocol, in improving strength, range of motion (ROM), muscle activity, pain, and functionality in patients with CTS. STUDY DESIGN: Randomized clinical trial. METHODS: Thirty-nine participants with unilateral CTS were divided into two groups: (i) MT group (n = 20) that followed an exercise protocol applied to the unaffected hand reflected in a mirror, and (ii) TE group (n = 19) that followed the same exercise protocol using the unaffected hand but without a mirror. Strength, wrist ROM, muscle activity, pain and functionality, were assessed at baseline (T0), after treatment (T1) and one month after treatment (T2). RESULTS: At T1, the MT group showed significantly higher wrist flexion-extension ROM compared to TE (p = 0.04, d = 0.8), maintained at T2 (p = 0.02, d = 0.8). No significant changes were observed in ulnar-radius deviation, pronosupination, or fatigue following either MT or TE (p > 0.05). MT exhibited enhanced handgrip strength at T1 (p = 0.001, d = 0.7), as well as an increase in the extensor carpi radialis (ECR) and flexor carpi radialis (FCR) maximum muscle activity (p = 0.04, d = 1.0; p = 0.03, d = 0.4). At T1, both groups decreased pain (p = 0.002, d = 1.1; p = 0.02, d = 0.7), and improved functionality (p < 0.001, d = 0.8; p = 0.01, d = 0.5) (MT and TE respectively). DISCUSSION: MT led to enhancements in wrist flexion-extension movement, handgrip strength and functionality unlike TE. MT notably increased muscle activity, particularly in the ECR and FCR muscles. CONCLUSIONS: MT is a favorable strategy to improve wrist flexion-extension ROM, handgrip strength, ECR and FCR muscle activity, and functionality in people with unilateral CTS.

Effects of mirror neuron activation therapies on functionality in older adults: Systematic review and meta-analysis.

PURPOSE: To identify the effects of mirror neuron activation (MNAT) combined or not with physical exercise (PE) in healthy older adults, on functionality, balance, gait velocity and risk of falls. METHODS: A systematic electronic search was performed in PubMed/MEDLINE, Cochrane, and Embase databases. RESULTS: Thirteen randomized controlled trials were included in the qualitative analysis, and eleven in the quantitative analysis. All studies showed fair to high quality and the most frequent high-risk bias was "Blinding of participants and personnel". Compared to the control condition, higher improvement was shown in older people who received MNAT, on functionality (1.57 [0.57, 2.62], balance (1.95 [1.32, 2.572]), and gait velocity (1.20 [0.30, 2.11]). Compared to PE, MNAT combined with PE does not improve functionality. More studies are needed to assess MNAT effectiveness in the rest of the outcomes. CONCLUSIONS: Neuron system activation through MNAT improves relevant abilities in older adults, with better results when including functional activities. However, the beneficial effects on these variables of adding MNAT to a PE program are controversial.

Therapeutic drug monitoring in inflammatory bowel diseases. Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis. / Monitorización terapéutica de los fármacos biológicos en la enfermedad inflamatoria intestinal. Documento de Posicionamiento del Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU).

The treatment of inflammatory bowel disease has undergone a significant transformation following the introduction of biologic drugs. Thanks to these drugs, treatment goals have evolved from clinical response and remission to more ambitious objectives, such as endoscopic or radiologic remission. However, even though biologics are highly effective, a significant percentage of patients will not achieve an initial response or may lose it over time. We know that there is a direct relationship between the trough concentrations of the biologic and its therapeutic efficacy, with more demanding therapeutic goals requiring higher drug levels, and inadequate exposure being common. Therapeutic drug monitoring of biologic medications, along with pharmacokinetic models, provides us with the possibility of offering a personalized approach to treatment for patients with IBD. Over the past few years, relevant information has accumulated regarding its utility during or after induction, as well as in the maintenance of biologic treatment, in reactive or proactive strategies, and prior to withdrawal or treatment de-escalation. The aim of this document is to establish recommendations regarding the utility of therapeutic drug monitoring of biologics in patients with inflammatory bowel disease, in different clinical practice scenarios, and to identify areas where its utility is evident, promising, or controversial.

Effects of a low-pressure hyperbaric oxygen therapy on psychological constructs related to pain and quality of life in women with fibromyalgia: A randomized clinical trial.

BACKGROUND AND OBJECTIVES: Self-reported psychological variables related to pain have been posited as the major contributors to the quality of life of fibromyalgia (FM) women and should be considered when implementing therapeutic strategies among this population. The aim of this study was to explore the effect of low-pressure hyperbaric oxygen therapy (HBOT) on psychological constructs related to pain (i.e., pain catastrophism, pain acceptance, pain inflexibility, mental defeat) and quality of life in women with FM. METHODS: This was a randomized controlled trial. Thirty-three women with FM were randomly allocated to a low-pressure hyperbaric oxygen therapy group (HBOTG) (n=17), who received an 8-week intervention (5 sessions per week), and a control group (CG) (n=16). All women were assessed at baseline (T0) and upon completion of the study (T1) for self-perceived pain intensity, pain catastrophism, pain acceptance, pain inflexibility, mental defeat and quality of life. RESULTS: At T1, the HBOTG improved across all variables related to pain (i.e. self-perceived pain intensity, pain catastrophism, pain acceptance, pain flexibility, mental defeat) (p<0.05) and quality of life (p<0.05). In contrast, the CG showed no improvements in any variable. Furthermore, significant differences between the groups were found in quality of life (p<0.05) after the intervention. CONCLUSIONS: HBOT is effective at improving the psychological constructs related to pain (i.e. pain catastrophism, pain acceptance, pain flexibility, mental defeat) and quality of life among women with FM.

Effects of an Oral Stimulation Program on Feeding Outcomes in Preterm Infants: A Systematic Review and Meta-Analysis.

AIMS: To review the literature on the effects of unimodal sensorimotor stimulation protocols on feeding outcomes in very preterm and moderate to late preterm infants (PIs). METHODS: Five databases were searched up to April 2022. Studies comparing unimodal sensorimotor stimulation protocols based on the combination of manual oral stimulation with NNS against usual care in PIs, on-time transition to full oral feeding (FOF), feeding efficacy, length of hospital stay, and/or body weight gain. RESULTS: Eleven studies were included. Compared to usual care, unimodal sensorimotor stimulation protocols based on manual oral stimulation combined with NNS demonstrated to be more effective in decreasing time transition to FOF (standardized mean difference [95%CI] - 1.08 [-1.74, -0.41]), improving feeding efficacy (2.15 [1.18, 3.13]) and shortening length of hospital stay (-0.35 [-0.68, -0.03]). However, the proposed intervention was not effective in improving weight gain (0.27 [-0.40, 0.95]). There were no significant differences according to gestational age (p > .05). CONCLUSIONS: Based on fair-to-high quality evidence, unimodal sensorimotor stimulation protocols combined with NNS reduce time transition to FOF, improve feeding efficacy, and shorten the length of hospital stay; yet the proposed intervention yielded no significant effects on body weight gain when compared to usual care in PIs.

Effectiveness of a heart disease blended learning program in physiotherapy students: a prospective study.

Background: In recent years, novel teaching methodologies have been emerging with the aim of improving student learning. One of them is known as Blended Learning. BL allows educators to integrate elements of traditional face-to-face teaching with tailored online learning modalities, integrating the distinct strengths of both methodologies. Purpose: To determine the effectiveness of a heart disease blended learning program in undergraduate physiotherapy students. Methods: 124 participants (average age 21.20 ± 4.67 years, 58.87% female) performed an 8-week heart disease blended learning program that included face-to-face classes and online resources. Knowledge was assessed at baseline, at 4, 8, 12 and 20 weeks. Motivation and engagement were assessed at 4 and 8 weeks. Design of the instructions and learning behaviors were measured at 8 weeks. Finally, 108 subjects completed the study. Results: Knowledge significantly increased mid-program (p = 0.02), at the end of the program (p < 0.001), at 12 weeks (p < 0.001) and 20 weeks (p = 0.001). After the intervention, a high intrinsic motivation was shown (5.60 ± 0.80)) over 7), whilst extrinsic motivation scored 4.24 ± 0.97 over 7.Finally, engagement (3.98 ± 0.52) over 5), design of the instructions (4.15 ± 0.62) over 5) and learning behaviors (70.51 ± 36.08) downloads, 28.97 ± 16.09) topics visited, and online questionnaires scored 7.67 ± 1.60) over 10) reported adequate scores. Conclusion: This program seems to be an appropriate methodology in future physiotherapists, since it improved knowledge and participants exhibited a high motivation and an adequate engagement, design of the program instructions and learning behaviors.

Transcranial direct current stimulation for post-stroke dysphagia: a meta-analysis.

BACKGROUND: Strokes may cause some swallowing difficulty or associated dysphagia in 25-80% of patients. This phenomenon has been linked to increased morbidity and mortality. Therefore, the aim of this study was to evaluate the efficacy of transcranial direct current stimulation in patients with dysphagia in post-stroke patients. METHODS: A systematic search in PubMed, Scopus, Web of Science and MEDLINE was conducted. The articles must have to evaluate an intervention that included transcranial direct current stimulation; the sample had to consist exclusively of patients with post-stroke dysphagia; and the experimental design consisted of randomized controlled trial. Difference in mean differences and their 95% confidence interval were calculated as the between-group difference in means divided by the pooled standard deviation. The I2 statistic was used to determine the degree of heterogeneity. RESULTS: Of the 9 investigations analyzed, all applied transcranial direct current stimulation in combination with conventional dysphagia therapy to the experimental group. All the studies analyzed identified improvements in swallowing function and meta-analysis confirmed their strong effect on reducing the risk of penetration and aspiration (Hedges's g = 0.55). The results showed that participants who received transcranial direct current stimulation significantly improved swallowing function. CONCLUSIONS: Transcranial direct current stimulation has positive effects in the treatment of poststroke dysphagia by improving swallowing function, oral and pharyngeal phase times and the risk of penetration and aspiration. Furthermore, its combination with conventional dysphagia therapy, balloon dilatation with catheter or training of the swallowing muscles ensures improvement of swallowing function.

Proposal for a physiotherapy assessment form for the evaluation of women patients with uro-gynecological disorders: A Delphi study.

BACKGROUND: The correct selection of treatment techniques and methods in physiotherapy depends directly on a well-structured anamnesis, examination and assessment. Within urogynecological and obstetric physiotherapy there is no standardized and protocolized assessment that allows to follow established steps. For all this, the main objective of this study was to identify the assessment items that should be included in the a physiotherapeutic uro-gynecological assessment. METHODS: Delphi study through a group of experts. Prior to this, a systematic search was carried out, accompanied by a review of grey literature, to obtain the possible items to be included in the forms. Subsequently, a Delphi study with two consecutive rounds of questionnaires was developed. A total of 6 expert physiotherapists participated in the study. RESULTS: The initial questionnaire had 97 items and after two rounds one item was eliminated to obtain a total of 96 items in the final questionnaire. CONCLUSIONS: The experts agreed on most of the choices and finally obtained a standardized and protocolized assessment in uro-gynecological physiotherapy. Furthermore, this proposal should be considered by other professionals involved in the process of evaluation and treatment of pelvi-perineal alterations.

Short-Term Effects of Manual Therapy on Balance: A Multicenter, Randomized, Double-Blind Controlled Trial.

OBJECTIVE: The purpose of this study was to analyze short-term changes in dynamic and static balance after a manual therapy protocol in healthy participants and analyze any repercussions on mood and perception of change after applying articulatory techniques. METHODS: A single-blind, randomized, multicenter clinical trial was conducted. Participants were allocated to either a manual therapy group (MTG) (n = 101) or a control group (CG) without intervention (n = 99), and measures were taken before treatment, after the intervention, and 1 week after treatment. Assessments included the Star Excursion Balance Test, Unipedal Stance Test (UPST), Profile of Mood States (POMS), and Patient Global Impression of Change (PGIC) scale. RESULTS: Two hundred healthy participants completed the study (mean age, 22 [SD = 2.67]). There was a statistically significant interaction between groups and time measurements in the right leg for anterior (P = .003), posteromedial (P < .001), and posterolateral (P = .001) directions in favor of the MTG, as well as in the left leg for anterior (P < .001), posteromedial (P < .001), and posterolateral (P = .012) directions. The analysis failed to show statistically significant interactions between any of the factors for the UPST and POMS (P > .05). The MTG showed a significant improvement compared to the CG after treatment (P = .003) and at 1-week follow-up (P < .001) on the PGIC scale. CONCLUSION: The results suggest the MT intervention was effective on dynamic balance in post-intervention in healthy participants, and some of the directions maintained the results at 1-week follow-up. Perception of change in post-treatment and 1-week follow-up also significantly improved. The protocol did not seem to produce changes in static balance and mood states. Positive changes after manual therapy were maintained in the short term.

Very long-term follow-up after aortic stenting for coarctation of the aorta.

INTRODUCTION AND OBJECTIVES: Stent implantation is the preferred treatment in older children and adults with aortic coarctation (CoA). We aimed to determine the incidence of very late events after CoA stenting. METHODS: We analyzed a cohort of CoA patients who underwent stent implantation at our center between 1993 and 2018. Patients were periodically followed up in outpatient clinics, including computed tomography (CT) and fluoroscopy assessment. RESULTS: A total of 167 patients with CT and fluoroscopy data were included: 83 (49.7%) were aged ≤ 12 years and 46 (28%) were female. The mean clinical follow-up time was 17±8 (range 4-30) years and the mean time to CT/fluoroscopy was 11±7 years. Aortic aneurysm was present in 13% and was associated with the PALMAZ stent (OR, 3.09; 95%CI, 1.11-9.49; P=.036) and the stented length (OR, 0.94; 95%CI, 0.89-0.99; P=.039). Stent fracture was frequent (34%), but was not related to the presence of aneurysm. Stent fracture was associated with young age (OR, 3.57; 95%CI, 1.54-8.33; P=.003), male sex (OR, 4.00; 95%CI, 1.51-12.5, P=.008) and inversely with the PALMAZ stent (OR, 0.29; 95%CI, 0.12-0.67, P=.005). Reintervention was lower in adults (10%), mainly related to aneurysms. Those treated when aged ≤ 12 years had higher reintervention rates (43%) due to recoarctation somatic growth. CONCLUSIONS: This long-term follow-up study of CoA patients treated with stenting revealed a significant incidence of late events. Reintervention rates were higher in patients treated at younger ages. Periodic imaging surveillance appears to be advisable.

Effects of mirror therapy on pain, sensitivity and functionality in patients with unilateral carpal tunnel syndrome. Randomised control trial.

PURPOSE: To investigate the effects of mirror therapy (MT) and therapeutic exercise (TE) with the unaffected hand, on pain, sensitivity and functionality in individuals with unilateral carpal tunnel syndrome (CTS). MATERIAL AND METHODS: A randomized controlled trial was carried out. Thirty-nine adults with unilateral CTS were included and randomly allocated to a six-week training programme based on MT (n = 20) or TE (n = 19). Visual Analogue Scale, Semmes-Weinstein monofilament test, Two-point discrimination (2PD), Disabilities of the Arm, Shoulder and Hand (DASH) and Boston Carpal Tunnel Questionnaire (BCTQ) were assessed before (T0) and after the intervention (T1), and at one-month follow-up (T2). RESULTS: At T1, MT and TE showed significant improvements in pain (p = 0.001 and p = 0.03, respectively), however, only MT maintained the achieved effects at T2 (p = 0.01). In addition, 2PD significantly improved in MT in the first (p = 0.04) and fourth fingers (p = 0.02) at T1. The DASH score decreased at T1 in MT (p < 0.001) and TE (p = 0.01). Additionally, the BCTQ score improved in MT (p < 0.001), and TE (p < 0.001) at T1. The effects were maintained at T2 for DASH and BCTQ scores. CONCLUSIONS: Training of the unaffected hand resulted in a significant improvement of the affected hand in both groups; nevertheless, MT achieved a longer duration of the effects.

Training of the unaffected hand may improve pain, sensitivity and functionality in people with unilateral tunnel carpal syndrome.Mirror therapy achieved longer duration of the effects on pain and hand functionality.Our research may inform clinical decision-making and guide the development of therapeutic interventions for patients with carpal tunnel syndrome.

N-acetylcysteine modulates redox imbalance and inflammation in macrophages and mice exposed to formaldehyde.

This study aimed to evaluate the protective role of N-acetylcysteine (NAC) in cells and mice exposed to formaldehyde. For the in vitro study, J774A.1 macrophages cells were incubated for 8, 16 and 24 h with formaldehyde or NAC to assess cell viability and reactive oxygen species (ROS). In the in vivo study, C57BL/6 mice (n = 48) were divided into 6 groups: control (CG), vehicle (VG) that received saline by orogastric gavage, a group exposed to formaldehyde 1% (FG) and formaldehyde exposed groups that received NAC at doses of 100, 150 and 200 mg/Kg (FN100, FN150 and FN200) for a period of 5 days. In vitro, formaldehyde promoted a decrease in cell viability and increased ROS, while NAC reduced formaldehyde-induced ROS production. Animals exposed to formaldehyde presented higher leukocyte counts in the blood and in the bronchoalveolar lavage fluid, and promoted secretion of inflammatory markers IL-6, IL-15, and IL-10. The exposure to formaldehyde also promoted redox imbalance and oxidative damage characterized by increased activities of superoxide dismutase, catalase, decreased GSH/GSSG ratio, as well as it increased levels of protein carbonyls and lipid peroxidation. NAC administration after formaldehyde exposure attenuated oxidative stress markers, secretion of inflammatory mediators and lung inflammation. In conclusion, both in in vitro and in vivo models, NAC administration exerted protective effects, which modulated the inflammatory response and redox imbalance, thus preventing the development airway injury induced by formaldehyde exposure.

A novel low-cost plug-and-play multi-spectral LED based fluorometer, with application to chlorophyll detection.

In this paper a novel low-cost multi-spectral optical fluorometer is presented and evaluated. The device uses a range of LEDs in the blue and violet regions of the electromagnetic spectrum and a mini-spectrometer to detect the emitted fluorescence in the UV to IR spectrum region. Custom built electronics and software were designed to control the system and the components were housed in bespoke 3D printed parts. A number of known fluorophores were tested to determine the capabilities of the fluorometer. Application of the device is demonstrated for the detection of chlorophyll a (Chl a) from laboratory grown algae and from environmental samples while analytical performance is established using both in vivo and extracted Chl a fluorescence and by comparison with a benchtop fluorometer.

Fibromyalgia syndrome is associated with sexual dysfunction regardless of physical activity status: a cross-sectional study.

BACKGROUND: Fibromyalgia syndrome (FMS) is a rheumatic disorder that has been observed to affect self-perception of sexuality. AIM: The study aims to assess sexual dysfunction (SD), establish possible associations with SD levels, and evaluate the impact of physical activity (PA) levels on SD in Spanish women with FMS as compared with healthy control women. METHODS: The study was cross-sectional. A total of 170 women voluntarily agreed to participate between September 2019 and February 2020: 88 in the FMS group and 82 in the control group. OUTCOMES: The main outcome measures were SD, as assessed through the Female Sexual Function Index (FSFI), and PA levels, as assessed with a structured interview. RESULTS: There were significant differences in every domain and total SD score between the FMS and control groups (P < .05). In addition, we obtained a moderate significant direct association (χ2[1] = 37.071, P < .05, phi = 0.467) when exploring the associations between FMS and risk of SD. Results showed statistically significant differences between the FMS group and the control group when PA levels were not reached in the desire, pain, and total scores of the FSFI (P < .05). When the PA levels were reached, between-group differences were found in all domains, as well as in the total score of the FSFI (P < .05). CLINICAL IMPLICATIONS: Sexual function should be evaluated in women with FMS, while future treatments should address this clinical area with the aim of managing SD in this population. STRENGTHS AND LIMITATIONS: The main limitation is that the outcome measures were self-reported. CONCLUSION: We found a high prevalence of SD in Spanish women with FMS, with an impact on aspects such as desire, arousal, lubrication, orgasm, satisfaction, and pain during sexual intercourse. In addition, there is a moderate direct association between FMS and SD. Ultimately, the results showed that, irrespective of PA, women with FMS reported increased SD.

Effects of high-intensity interval training with an eccentric hamstring exercise program in futsal players: A randomized controlled trial.

BACKGROUND: Physiotherapy protocols based on high-intensity interval training (HIIT) or eccentric hamstring exercises like Nordic Curl (NC) have been scarcely studied in futsal players. The objective of this study was to compare the effectiveness of a HIIT combined with an NC exercise program versus a HIIT-only program in futsal players. METHODS: Twenty-one futsal players were divided into (1) HIIT + NC group (n = 11, mean age = 21.55 [4.25]); and (2) HIIT group (n = 10, mean age = 20.90 [1.29]). The HIIT + NC group performed a HIIT circuit combined with 3 sets of 10 NC repetitions for 4 weeks, while the HIIT group performed the same protocol without NC exercise. Body mass index, intermittent work performance, vertical jump performance without and with arms, isometric strength of quadriceps and hamstrings, and the isometric hamstrings/quadriceps (H/Q) ratio, were assessed before and after the interventions. RESULTS: The HIIT + NC group and the HIIT group showed a significant improvement in intermittent work performance after the intervention (P = .04 and P = .01, respectively). Also, both groups showed a trend of increasing quadriceps and hamstring isometric strength, although no significant changes were found (P > .05). In addition, neither the HIIT + NC protocol nor the HIIT protocol was sufficient to yield changes in body mass index nor to improve the vertical jump performance (P > .05). CONCLUSION: Both an isolated HIIT protocol and HIIT in combination with NC exercise improved intermittent work performance in futsal players. The present study's findings may guide futsal players' physical preparation and injury prevention programs.
