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.

During pregnancy, women undergo several metabolic changes to guarantee an adequate supply of glucose to the foetus. These metabolic modifications develop what is known as physiological insulin resistance. When this process is altered, however, gestational diabetes mellitus (GDM) occurs. GDM is a multifactorial disease, and genetic and environmental factors play a crucial role in its aetiopathogenesis. GDM has been linked to both macroscopic and molecular alterations in placental tissues that affect placental physiology. This review summarizes the role of the placenta in the development of GDM from a molecular perspective, including hormonal and pro- inflammatory changes. Inflammation and hormonal imbalance, the characteristics dominating the GDM microenvironment, are responsible for placental changes in size and vascularity, leading to dysregulation in maternal and foetal circulations and to complications in the newborn. In conclusion, since the hormonal mechanisms operating in GDM have not been fully elucidated, more research should be done to improve the quality of life of patients with GDM and their future children.

Sleep is a crucial physiological process that promotes human health and well-being. Physical activity and sports participation are known to improve sleep quality in adolescents. The objective was to investigate how the characteristics of different sports affected this relationship in elite athletes. This cross-sectional study analyzed data from 1,831 young Spanish elite athletes (1,059 males and 772 females) from 11 to 20 years old who self-reported their sleep quality using the Pittsburgh Questionnaire and provided information on their sports practice. Technical sports reported significantly better sleep quality than team sports (p=.004, d =- 0.39, small). Additionally, individual competition sports reported better sleep quality than team competition sports (p=.033, d=-0.15, trivial). Differences by the type of metabolism were not statistically significant. Better sleep quality was reported in outdoors training environment sports compared to indoors training environment sports (p=.023, d=-0.11, trivial). The type of sports practiced may influence sleep quality in adolescents and highlights the importance of considering sport characteristics when promoting sleep health. Further research is necessary to explore the underlying mechanisms and to validate these findings across different age groups and populations.

Background: Malnutrition, sedentary lifestyle, cognitive dysfunction and poor psychological well-being are often reported in patients on haemodialysis (HD). Aims: We aimed to explore needs, barriers and facilitators—as perceived by patients, their carers, and healthcare professionals (HCPs) for increasing the adherence to the diet, to physical activity and cognition and psychological well-being. Methods: This is an observational cross-sectional study following the STROBE statement. This study is part of an ERASMUS+ project, GoodRENal—aiming to develop digital tools as an educational approach to patients on HD. For that, the GoodRENal comprises HD centers located in four Belgium, Greece, Spain and Sweden. Exploratory questionnaires were developed regarding the perceived needs, barriers and facilitators regarding the diet, physical activity, cognition and psychological well-being from the perspective of patients, their carers and HCPs. Results: In total, 38 patients, 34 carers and 38 HCPs were included. Nutrition: For patients and carers, the main needs to adhere to the diet included learning more about nutrients and minerals. For patients, the main barrier was not being able to eat what they like. Physical activity: As needs it was reported information about type of appropriate physical activity, while fatigue was listed as the main barrier. For Cognitive and emotional state, it was perceived as positive for patients and carers perception but not for HCPs. The HCPs identified as needs working as a team, having access to specialised HCP and being able to talk to patients in private. Conclusions: Patients and their carers listed as needs guidance regarding nutrition and physical activity but were positive with their cognitive and emotional state. The HCPs corroborated these needs and emphasised the importance of teamwork and expert support.

Purpose: Many patients with acute coronary syndrome experience problematic or altered sexual function. This aspect of the disease is frequently ignored or overlooked by the healthcare community even though it can strongly influence health-related patient quality of life (HRQoL). Thus, the aim of this study was to compare the effects of a specific cardiac rehabilitation programme focused on aerobic and neuromuscular strength-resistance training to those of a classic rehabilitation programme, both in terms of HRQoL and erectile dysfunction in patients with acute coronary syndrome. Methods: This study reports both secondary and unregistered outcomes from a double-blinded, randomised, and controlled clinical trial. The proposed intervention was based on the completion of a 20-session (10-week) cardiac rehabilitation programme for patients with cardiovascular disease. The patient cohort had been diagnosed with acute coronary syndrome and was recruited at the Cardiology Service of a private tertiary hospital. The outcomes assessed in this study were HRQoL and erectile disfunction assessed at baseline, after the intervention, and at a 6-month follow-up. Results: A total of 30 participants were randomly allocated to each study arm. The results of the two-way mixed ANOVAs showed significant group × time interactions for all the outcome measures (EQ-5D_index, p = 0.004; EQ-5D_VAS, p = 0.017; QLMI-Q, p ≤ 0.001; and IIEF-5, p = 0.001). Conclusion: The neuromuscular strength training programme was more effective than the classic strength training programme in terms of increasing the HRQoL and improving erectile dysfunction in patients following acute coronary syndrome, with differences still remaining between these groups at the 6-month follow-up.

BACKGROUND: There are still many barriers when implementing exercise routines within daily dialysis care, even though benefits are well-known. Developing cost-effective strategies is necessary to overcome these barriers and include exercise as a complementary therapy in dialysis. AIM: To compare several exercise programs on hemodialysis patient’s functional capacity and health-related quality of life. DESIGN: This study was a 16-week follow-up, two-parallel group trial with balanced randomization. SETTING: Participants in this study belonged to a private hospitalized care center. POPULATION: Referred sample of 71 patients that suffered end-stage chronic kidney disease who underwent hemodialysis for at least 3 months and had a medical stable condition. METHODS: Thirty-six participants performed for 16 weeks an intradialytic exercise program lead by the nursing staff of the hemodialysis unit and 35 a home-based program supervised by physical therapists of the hospital. RESULTS: The main researcher and the data analyst were both blinded to participant allocation. There was a significant effect in time for both groups. Participants improved significantly in the Short Performance Physical Battery (SPPB), One-Leg Heel-Rise (OLHR) and 6 Minute-Walk Test (6MWT), and in the Physical Activity Scale for the Elderly (PASE) and Short Survey Form 36 (SF-36) questionnaires. CONCLUSIONS: Nurse-led and home-based exercise interventions produce beneficial effects involving physical function, activity levels and health-related quality of life in patients undergoing hemodialysis. CLINICAL REHABILITATION IMPACT: The study emphasizes the importance of exercise rehabilitation routines in fragile populations such as dialysis patients, and the potential to overcome barriers for its daily implementation.

Background: Exercise programs in patients with kidney disease improve functional capacity and health-related quality of life, but the implementation of exercise programs in nephrology services is not an easy task. Aim: To evaluate the effectiveness of a home-based exercise program in patients with chronic kidney disease (CKD) stages 4–5 (with or without dialysis). Methods: A 12-week prospective observational cohort design study was carried out with patients with renal failure who undertook a home-based exercise program. Registered data included: (a) biochemical parameters; (b) functional capacity tests, that is, short physical performance battery, sit to stand to sit 10, and 6-min walking test; (c) handgrip strength; (d) health-related quality of life; (e) satisfaction; and (f) adherence. The quantitative variables were expressed by means and standard deviation, and qualitative variables, by percentage. The comparison of quantitative data between baseline and at 12 weeks of the same group was carried out using the Wilcoxon test for nonparametric-related variables and the chi-square test for categorical variables using contingency tables. Results: Fifty-three patients were included (mean age = 67.4 years). The functional capacity tests showed a significant improvement in the short physical performance battery (8.3 ± 2.8 vs. 9.5 ± 2.6 points), the sit to stand to sit 10 (35.8 ± 17.7 vs. 31.8 ± 15.3 s), and the 6-min walking test (355.0 ± 106.1 vs. 386.4 ± 113.6 meters), mainly in CKD stage 5. There were no significant differences in handgrip and health-related quality of life. Regarding the degree of program satisfaction, 70% of the patients were very satisfied with being able to participate in the program, and 64% considered that they had more strength after completing the home-based exercise program. Linking Evidence to Action: The implementation of a home-based exercise program results in improved functional capacity in patients with CKD stage 5. Moreover, this exercise program is safe, and patients were satisfied.

Background: Intradialysis exercise programs in renal patients result in improved functional capacity, muscle strength, symptoms of depression, and health-related quality of life. Home-based exercise programs are an alternative to overcome logistical and human resource problems. However, the implementation of these programs is not an easy task and there is a lack of knowledge regarding the benefits associated with home-based exercise programs. Aim: To determine whether home-based exercise programs improve functional capacity, health-related quality of life, muscle strength, and symptoms of depression among patients with stage III–V chronic kidney disease. Methods: A systematic review and meta-analyses following PRISMA guidelines were utilized. Relevant articles were collected and independently assessed for their inclusion eligibility. Effects of home-based exercise were summarized by the standardized mean differences and represented by forest plots (Review Manager 5.4). Results: Eight studies were included, none of which reported any adverse effects. The intervention was usually aerobic, 76% of these programs lasted 3–6 months, and exercise adherence was 60–87.5%. Four studies measured health-related quality of life and found significant improvements in several subscales. Regarding functional capacity, five studies used the six-minute walking test (44.9 meters; 95% CI [30.45, 59.30]; p ≤ .001), three studies used the sit-to-stand-to-sit test (−0.45 seconds; 95% CI [−0.46, −0.26]; p ≤ .001), and two studies used the timed up-and-go test (−0.76 seconds; 95% CI [−1.38, −0.15]; p ≤ .001) and the handgrip strength test (1.16 kg; 95% CI [−2.88, 5.20]; p ≤ .001). LINKING EVIDENCE TO ACTION: Home-based exercise programs are beneficial to renal patients. These interventions are safe and effective to improve health-related quality of life and functional capacity and reduce symptoms of depression among patients with chronic kidney disease.

Background: Diagnosis and treatment of differentiated thyroid carcinomas (DTC) cause anxiety and depression. Additionally, these patients suffer hormonal alterations that are associated with psychological symptoms (e.g., changes in mood, emotional instability, and memory loss). This study aims to evaluate the effectiveness of a psycho-oncological intervention based on counseling to reduce anxiety and depression related to the treatment in patients with DTC. Methods: A non-randomized controlled study, with two groups [experimental group (EG), n = 37, and control group (CG), n = 38] and baseline and posttreatment measures, was designed. Patients in the EG received a psycho-oncological intervention based on counseling in addition to the standard treatment. The independent variable was the assigned group and the dependent one was the evolution of anxiety and depression, which were analyzed separately, and both were evaluated using the Hospital Anxiety and Depression Scale. Other relevant covariables related to the quality of life (QoL) were also analyzed using Short Form-36 Health Survey and Psychological General Wellbeing Index scales. Results: The difference of the posttreatment-baseline variation showed a statistically significant reduction in anxiety and depression in the EG in relation to the CG (p < 0.001). The mean of the Psychological General Wellbeing Index scales score increased significantly in the EG (p < 0.001) and decreased significantly in the CG (p < 0.001). All the baseline and the posttreatment scores of the variables evaluated showed a statistically significant improvement in the EG vs. the CG. Conclusion: This study demonstrates significant benefits of psycho-oncological intervention based on counseling in anxiety, depression, QoL, and wellbeing of the patient with differentiated thyroid carcinomas.

Las supervivientes de cáncer de cérvix constituyen un grupo especialmente vulnerable al empobrecimiento de la calidad de vida a largo plazo. La evaluación de la calidad de vida mediante el empleo de resultados autoinformados puede ser útil para medir la calidad terapéutica e incluso tener un valor pronóstico. Los efectos adversos del tratamiento oncológico constituyen una importante variable explicativa de la calidad de vida, por tanto resulta prioritario predecir su riesgo de aparición. Objetivos: Diseñar modelos predictivos de supervivencia, efectos adversos del tratamiento oncológico y calidad de vida de supervivientes de cáncer de cérvix. Material y métodos: Realizamos un estudio de cohortes prospectivo en el Hospital Universitario Virgen Macarena (Sevilla, España) entre enero de 2010 y enero de 2019 con 229 pacientes con cáncer de cérvix. Empleamos el cuestionario de calidad de vida autoadministrado FACT-Cx v4.0. La función sexual fue evaluada mediante el FSFI. Desarrollamos modelos de Cox y modelos lineales generalizados (GLM). Resultados y conclusiones: La supervivencia, los efectos adversos del tratamiento oncológico, la calidad de vida y la función sexual de las pacientes con cáncer de cérvix pueden explicarse mediante modelos predictivos sólidos, con un ajuste óptimo y validación interna.
