A potent and selective activator of large-conductance Ca2+-activated K+ channels induces preservation of mitochondrial function after hypoxia and reoxygenation by handling of calcium and transmembrane potential.

AIMS: Ischaemic heart disease remains a significant cause of mortality globally. A pharmacological agent that protects cardiac mitochondria against oxygen deprivation injuries is welcome in therapy against acute myocardial infarction. Here, we evaluate the effect of large-conductance Ca2+-activated K+ channels (BKCa) activator, Compound Z, in isolated mitochondria under hypoxia and reoxygenation. METHODS: Mitochondria from mice hearts were obtained by differential centrifugation. The isolated mitochondria were incubated with a BKCa channel activator, Compound Z, and subjected to normoxia or hypoxia/reoxygenation. Mitochondrial function was evaluated by measurement of O2 consumption in the complexes I, II, and IV in the respiratory states 1, 2, 3, and by maximal uncoupled O2 uptake, ATP production, ROS production, transmembrane potential, and calcium retention capacity. RESULTS: Incubation of isolated mitochondria with Compound Z under normoxia conditions reduced the mitochondrial functions and induced the production of a significant amount of ROS. However, under hypoxia/reoxygenation, the Compound Z prevented a profound reduction in mitochondrial functions, including reducing ROS production over the hypoxia/reoxygenation group. Furthermore, hypoxia/reoxygenation induced a large mitochondria depolarization, which Compound Z incubation prevented, but, even so, Compound Z created a small depolarization. The mitochondrial calcium uptake was prevented by the BKCa activator, extruding the mitochondrial calcium present before Compound Z incubation. CONCLUSION: The Compound Z acts as a mitochondrial BKCa channel activator and can protect mitochondria function against hypoxia/reoxygenation injury, by handling mitochondrial calcium and transmembrane potential.

The use of a biopsychosocial model in the treatment of patients with chronic.

OBJECTIVE: To explore the available knowledge on the application of biopsychosocial model (BPS) in patients with chronic low back pain (CLBP). METHODS: A scoping review, including 32 papers that used a BPS to manage adult patients with CLBP, published in any language. Six different databases were searched. RESULTS: According to the description of the protocols, most of them use BPS for assessment of the patients. In this first stage the most often evaluated were pain and disability, kinesiophobia and quality of life, and work-related factors. The intervention most used associate psychological and physical domains using pain education or cognitive functional therapy and active exercise. Even though was not the most common, in the social domain occupational, behavioral and family interventions were observed. CONCLUSION: BPS is more often used as combination of physical and psychological aspects, being the social domain restricted to work-related factors. Patien'ts perception of their health status is little explored, and it is suggested that the International Classification of Functioning, Disability and Health be used. PRACTICE IMPLICATION: Patient perception as well as social factors in addition to occupational ones should be included in the clinical approach of the patient with CLBP and should be further explored in research.

Extracellular Vesicles and Cardiac Aging.

Global population aging is a major challenge to health and socioeconomic policies. The prevalence of diseases progressively increases with aging, with cardiovascular disease being the major cause of mortality among elderly people. The allostatic overload imposed by the accumulation of cardiac senescent cells has been suggested to play a pivotal role in the aging-related deterioration of cardiovascular function. Senescent cells exhibit intrinsic disorders and release a senescence-associated secretory phenotype (SASP). Most of these SASP compounds and damaged molecules are released from senescent cells by extracellular vesicles (EVs). Once secreted, these EVs can be readily incorporated by recipient neighboring cells and elicit cellular damage or otherwise can promote extracellular matrix remodeling. This has been associated with the development of cardiac dysfunction, fibrosis, and vascular calcification, among others. The molecular signature of these EVs is highly variable and might provide important information for the development of aging-related biomarkers. Conversely, EVs released by the stem and progenitor cells can exert a rejuvenating effect, raising the possibility of future anti-aging therapies.

Quercetin improves white adipose tissue redox homeostasis in ovariectomized rats.

Estrogen deficiency is a well-known hallmark of menopause and is associated with oxidative stress and metabolic dysfunction. Quercetin (Q), a flavonoid found in fruits and vegetables, has demonstrated anti-inflammatory effects in experimental models of metabolic disorders. In this study, we aimed to investigate the effects of quercetin on retroperitoneal white adipose tissue (rWAT) redox homeostasis and systemic metabolic parameters in ovariectomized (OVX) rats. Female Wistar rats at 3 months old were divided into the following experimental groups: sham-operated treated with vehicle (DMSO 10% + PBS - 1 mL/kg); OVX (vehicle treated) and OVX-Q (25 mg/kg) - via oral gavage, daily for 5 weeks. Q did not prevent weight gain but improved glucose tolerance and blood cholesterol profile, and attenuated uterine atrophy in OVX rats. Furthermore, Q had a protective effect on rWAT, once the OVX-Q group presented lower oxidative stress levels, and reduced levels of the pro-inflammatory cytokine tumor necrosis factor alpha, compared to the OVX group. Q improved antioxidant enzyme activities such as superoxide dismutase and catalase and decreased reactive oxygen species production, in OVX-Q rats. It was followed by increased levels of total thiol content and lower lipid peroxidation. Moreover, Q reduced senescent-related genes p16INK4a and p19ARF expression which were higher in the OVX group. In conclusion, quercetin supplementation improved redox homeostasis and reduced senescence-related markers, and inflammation in rWAT, which was reflected in preserved systemic metabolic health parameters in OVX rats. These findings suggest that quercetin may have therapeutic potential for the management of metabolic disorders associated with menopause-induced estrogen deficiency.

Aging Triggers Mitochondrial Dysfunction in Mice.

Direct analysis of isolated mitochondria from old mice enables a better understanding of heart senescence dysfunction. Despite a well-defined senescent phenotype in cardiomyocytes, the mitochondrial state in aged cardiomyocytes is still unclear. Here, we report data about mitochondrial function in old mice. Isolated cardiomyocytes' mitochondria were obtained by differential centrifugation from old and young mice hearts to perform functional analyses of mitochondrial O2 consumption, transmembrane potential, ROS formation, ATP production, and swelling. Our results show that mitochondria from old mouse hearts have reduced oxygen consumption during the phosphorylative states of complexes I and II. Additionally, these mitochondria produced more ROS and less ATP than those of young hearts. Mitochondria from old hearts also showed a depolarized membrane potential than mitochondria from young hearts and, as expected, a greater electron leak. Our results indicate that mitochondria from senescent cardiomyocytes are less efficient in O2 consumption, generating more ROS and producing less ATP. Furthermore, the phosphorylative state of complexes I and II presents a functional defect, contributing to greater leakage of protons and ROS production that can be harmful to the cell.

Effectiveness of physical therapy interventions in women with dyspareunia: a systematic review and meta-analysis.

BACKGROUND: Dyspareunia is defined as the occurrence of pain during or after sexual intercourse, which directly affects physical, sexual, and mental health. This condition can lead to depression, anxiety, and low self-esteem in women who experience it. OBJECTIVES: The aim of this research was to evaluate the effectiveness of physical therapy interventions for the treatment of female dyspareunia. DESIGN: A systematic review and meta-analysis was conducted. METHOD: Search of publications was conducted in Scopus, Medline, Pubmed, Cinahl and Web of Science. Treatment effects were defined as standardized mean difference and their 95% confidence intervals. Statistical heterogeneity was assessed using Crohan's Q test and quantified using the I2 index. RESULTS: Of the 19 articles selected, six applied multimodal physiotherapy treatments; five, electrotherapy; three, Thiele's massage; two, interdisciplinary interventions or pelvic floor muscle training; and one, extracorporeal shockwave therapy. The meta-analysis showed significant results for the variables pain and quality of life with the interventions based on electrotherapy and electrotherapy combined with pelvic floor muscle training. These interventions did not show significant results for the improvement of sexual function. CONCLUSIONS: Physiotherapy techniques are effective and procedures have been identified with reliable results in improving pain and quality of life in patients with dyspareunia. One of the most important aspects is the strengthening of the perineal musculature and the application of Transcutaneous Electrical Nerve Stimulation. Furthermore, manual trigger point release therapy and Thiele massage, optimize and guarantee the reduction of pain intensity. PROSPERO REGISTRATION: CRD42021236155.

Physicochemical, Rheological, and Nutritional Quality of Artisanal Fermented Milk Beverages with Cupuassu (Theobroma grandiflorum) Pulp and Flour.

The use of fruits and their by-products in food has dramatically impacted the food industry due to the nutritional benefits and the technological and sensory effects of food matrices. Therefore, this research aimed to evaluate the effects of adding cupuassu (Theobroma grandiflorum) pulp and flour on fermented milk beverages' physicochemical, microbial, and sensory properties during refrigerated storage (0, 7, 14, 21, and 28 days). Twelve formulations were realized with different percentages of cupuassu pulp (0, 5, 7.5, and 10% w/v) and flour (0, 1.5, and 3% w/v). The treatments with 3% cupuassu flour presented the highest percentages of protein, fat, fiber, and carbohydrates, compared with the samples containing pulp. On the other hand, the addition of pulp increased water retention capacity and color parameters (L*, a*, b*, and C*) and decreased pH and syneresis on day 0 of storage. During storage, the samples with pulp showed increases in pH values, consistency index, and apparent viscosity. In comparison, cupuassu flour addition decreased syneresis values and increased L* and b* during storage, as did pulp. In addition, sample HPHF (10% pulp and 3% cupuassu flour), based on just-about-right, penalty, and check-all-that-apply analyses, improved some sensory attributes of the fermented milk beverage, such as brown color, acid taste, bitter taste, cupuassu flavor, and firm texture. It can be concluded that cupuassu pulp and flour addition improves the physicochemical and sensory quality of fermented milk beverages and can provide nutritional value to the product.

Mitochondrial dysfunction and cardiac ischemia/reperfusion injury are attenuated by nandrolone: Role of JAK-STAT3 pathway.

AIM: To investigate the effect of acute treatment with the anabolic steroid (AS) nandrolone decanoate in mitochondrial homeostasis and JAK-STAT3 signaling during the progression of cardiac ischemia/reperfusion injury (IR). METHODS: Male Wistar rats (2 months old) were randomly allocated into four experimental groups: Control (CTRL), IR, AS, and AS + AG490. All animals were euthanized 3 days after a single intramuscular injection of nandrolone at 10 mg/kg (AS and AS + AG490 groups) or vehicle (CTRL and IR groups). Baseline mRNA expression of antioxidant enzymes superoxide dismutase (SOD) 1 and 2, glutathione peroxidase, catalase, and myosin heavy chain (MHC) α and ß were compared between CTRL and AS groups. Isolated hearts were submitted to ex vivo ischemia and reperfusion, except for hearts from the CTRL group. Before the IR protocol, the JAK-STAT3 inhibitor AG490 was perfused in hearts from the AS + AG490 group. Heart samples were collected during reperfusion to investigate the effects on mitochondrial function. Results Antioxidant enzyme mRNA expression was unaffected, whereas the AS group exhibited decreased ß- MHC/α-MHC ratio versus the CTRL group. Compared to the IR group, the AS group exhibited better recovery of post-ischemic left ventricular (LV) end-diastolic pressure and LV-developed pressure levels, while infarct size significantly decreased. Furthermore, mitochondrial production, transmembrane potential, and swelling were improved, whereas ROS formation was decreased versus the IR group. These effects were prevented by the perfusion of JAK-STAT3 inhibitor AG490. CONCLUSION: These findings suggest that acute nandrolone treatment can provide cardioprotection by recruiting the JAK-STAT3 signaling pathway and mitochondrial preservation.

Genetic Ablation and Pharmacological Blockade of Bradykinin B1 Receptor Unveiled a Detrimental Role for the Kinin System in Chagas Disease Cardiomyopathy.

Chagas disease, the parasitic infection caused by Trypanosoma cruzi, afflicts about 6 million people in Latin America. Here, we investigated the hypothesis that T. cruzi may fuel heart parasitism by activating B1R, a G protein-coupled (brady) kinin receptor whose expression is upregulated in inflamed tissues. Studies in WT and B1R-/- mice showed that T. cruzi DNA levels (15 days post infection-dpi) were sharply reduced in the transgenic heart. FACS analysis revealed that frequencies of proinflammatory neutrophils and monocytes were diminished in B1R-/- hearts whereas CK-MB activity (60 dpi) was exclusively detected in B1R+/+ sera. Since chronic myocarditis and heart fibrosis (90 dpi) were markedly attenuated in the transgenic mice, we sought to determine whether a pharmacological blockade of the des-Arg9-bradykinin (DABK)/B1R pathway might alleviate chagasic cardiomyopathy. Using C57BL/6 mice acutely infected by a myotropic T. cruzi strain (Colombian), we found that daily treatment (15-60 dpi) with R-954 (B1R antagonist) reduced heart parasitism and blunted cardiac injury. Extending R-954 treatment to the chronic phase (120-160 dpi), we verified that B1R targeting (i) decreased mortality indexes, (ii) mitigated chronic myocarditis, and (iii) ameliorated heart conduction disturbances. Collectively, our study suggests that a pharmacological blockade of the proinflammatory KKS/DABK/B1R pathway is cardioprotective in acute and chronic Chagas disease.

Cultural adaptation and validation of the "Pregnancy Physical Activity Questionnaire" for the Portuguese population.

BACKGROUND: The lack of instruments to assess the level of physical activity in pregnant women, led to the development of the PPAQ (Pregnancy Physical Activity Questionnaire), a self-administered questionnaire, which has already been translated in several countries and has already been used in several studies. AIM(S): Translate and adapt the PPAQ into Portuguese and test its reliability and validity. METHODS: An analytical observational study was carried out. Linguistic and semantic equivalence was performed through translation and back-translation and content validity was tested by a panel of experts. To test reliability, a test-retest was performed on a sample of 184 pregnant women, with an interval of 7 days and the ICC was used. To test the criterion validity, Pearson's correlation coefficient (r) was used between the PPAQ and the accelerometer, in a sample of 226 pregnant women. FINDINGS: The questionnaire was considered comprehensive. The ICC values of Reliability were: total score (0.77); sedentary activities (0.87); light-intensity activities (0.76); moderate-intensity activities (0.76); vigorous-intensity activities (0.70). For criterion validity was obtained a coefficient correlation of r = -0.030, considered weak and negative, for total activity. DISCUSSION: This study describes the translation and validation process of the PPAQ questionnaire from English to Portuguese. The final version of the PPAQ was considered as a valid instrument in terms of content to measure physical activity and was referred to as being simple to apply and easy to understand. CONCLUSION: The PPAQ has content validity, excellent reliability and weak criterion validity, as in the original version.

Efficacy of percutaneous electrolysis for the treatment of tendinopathies: A systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of percutaneous electrolysis for the treatment of patients with tendinopathies. DATA SOURCES: A systematic search of publications was conducted in Pubmed, Cinahl, Medline, Scopus and Web of Science. METHODS: The Oxford 2011 Levels of Evidence and the Jadad scale were used to assess the quality of studies. The mean and standard deviation were obtained for each study group and used to calculate the effect size. The DerSimonian and Laird method was used to develop a random-effects model. RESULTS: Of the 14 articles, four applied percutaneous electrolysis to the knee, three to the shoulder, three to the elbow, two to the hip and two to the ankle and foot. A meta-analysis on intensity of pain (evaluated with algometer and the Visual Analogue Scale) was performed on studies comparing percutaneous electrolysis with a control group, indicating that the groups treated with percutaneous electrolysis had better results (p = 0.01). Although percutaneous electrolysis did not overcome the analgesic effect achieved by corticosteroid injections. CONCLUSIONS: The percutaneous electrolysis is effective for the treatment of tendinopathies. The combination of this technique with eccentric training has proven to be one of the most effective treatments to date for improving pain. PROSPERO Registration: CRD42021230005.

Comparison between exercise therapy and non-hydrolyzed collagen (UC-II) in functionality and quality of life in women with knee osteoarthritis : A randomized controlled clinical trial.

BACKGROUND: Knee osteoarthritis (OA) is characterized by a progressive degeneration of cartilage and menisci, leading to pain and locomotor disability. Here, we aimed to assess the effect of an exercise protocol and the oral use of non-hydrolyzed collagen (UC-II) on the functionality and quality of life of women with knee OA. MATERIAL AND METHODS: Individuals were divided into three groups (CG [control group]; MG [medication group]; EG [exercise group]). In the CG there was no intervention, while MG received an oral dose (1 capsule/day) of UC-II and the EG held 12 sessions of an exercise protocol. RESULTS: In the functionality tests (6-min walk test, 6MWT and timed up and go test [TUG]) the EG (p < 0.001/p = 0.020) and MG (p = 0.010/p = 0.010) revealed a significant improvement when compared to the CG. In the analysis of quality of life by WOMAC, a significant improvement was found only in the EG (p = 0.030) when compared to the CG; the same happened in the stiffness domain (EG, p = 0.010), despite in the pain domain, both the EG (p < 0.001) and the MG (p = 0.060) were better than the CG. CONCLUSION: Data obtained here reveal that an exercise protocol and UC-II have similar effects for functionality, despite exercise being superior in promoting the quality of life score.

Impact of Long-Term Swimming Exercise on Rat Femur Bone Quality.

Considering the conflicting evidence regarding the potential long-term detrimental effect of swimming during growth on femur quality and fracture risk, our aim was to investigate the effect of eight months of swimming on femur quality. Twenty male eight-week-old Wistar rats were assigned into a swimming (SW; n = 10; 2 h/day, 5 days/week) or active control group (CG; n = 10, housed with running wheel) for eight months. Plasma osteocalcin and C-terminal telopeptide of type I collagen concentrations (ELISA) were assessed at baseline, four, and eight months of protocol. Femur structure (micro-computed tomography), biomechanical properties (three-point bending), and cellular density (histology) were determined after the protocol. SW displayed a lower uncoupling index, suggesting higher bone resorption, lower empty lacunae density, cortical and trabecular femur mass, femur length and cortical thickness, and higher cortical porosity than CG (p < 0.05). Although both biomarkers' concentrations decreased in both groups throughout the experiment (p < 0.001), there were no significant differences between groups (p > 0.05). No differences were also found regarding biomechanical properties, bone marrow adiposity, and osteocyte and osteoclast densities (p > 0.05). Long-term swimming was associated with unbalanced bone turnover and compromised femur growth, lower femur mass, and deteriorated cortical bone microarchitecture. However, femur trabecular microarchitecture and biomechanical properties were not affected by swimming.

Bone Tissue Responsiveness To Mechanical Loading-Possible Long-Term Implications of Swimming on Bone Health and Bone Development.

PURPOSE OF REVIEW: To revisit the bone tissue mechanotransduction mechanisms behind the bone tissue response to mechanical loading and, within this context, explore the possible negative influence of regular swimming practice on bone health, particularly during the growth and development period. RECENT FINDINGS: Bone is a dynamic tissue, responsive to mechanical loading and unloading, being these adaptative responses more intense during the growth and development period. Cross-sectional studies usually report a lower bone mass in swimmers compared to athletes engaged in weigh-bearing sports. However, studies with animal models show contradictory findings about the effect of swimming on bone health, highlighting the need for longitudinal studies. Due to its microgravity characteristics, swimming seems to impair bone mass, but mostly at the lower limbs. It is unkown if there is a causal relationship between swimming and low BMD or if other confounding factors, such as a natural selection whithin the sport, are the cause.

Exercise Improves Redox Homeostasis and Mitochondrial Function in White Adipose Tissue.

Exercise has beneficial effects on energy balance and also improves metabolic health independently of weight loss. Adipose tissue function is a critical denominator of a healthy metabolism but the adaptation of adipocytes in response to exercise is insufficiently well understood. We have previously shown that one aerobic exercise session was associated with increased expression of antioxidant and cytoprotective genes in white adipose tissue (WAT). In the present study, we evaluate the chronic effects of physical exercise on WAT redox homeostasis and mitochondrial function. Adult male Wistar rats were separated into two groups: a control group that did not exercise and a group that performed running exercise sessions on a treadmill for 30 min, 5 days per week for 9 weeks. Reactive oxygen species (ROS) generation, antioxidant enzyme activities, mitochondrial function, markers of oxidative stress and inflammation, and proteins related to DNA damage response were analyzed. In WAT from the exercise group, we found higher mitochondrial respiration in states I, II, and III of Complex I and Complex II, followed by an increase in ATP production, and the ROS/ATP ratio when compared to tissues from control rats. Regarding redox homeostasis, NADPH oxidase activity, protein carbonylation, and lipid peroxidation levels were lower in WAT from the exercise group when compared to control tissues. Moreover, antioxidant enzymatic activity, reduced glutathione/oxidized glutathione ratio, and total nuclear factor erythroid-2, like-2 (NFE2L2/NRF2) protein levels were higher in the exercise group compared to control. Finally, we found that exercise reduced the phosphorylation levels of H2AX histone (γH2AX), a central protein that contributes to genome stability through the signaling of DNA damage. In conclusion, our results show that chronic exercise modulates redox homeostasis in WAT, improving antioxidant capacity, and mitochondrial function. This hormetic remodeling of adipocyte redox balance points to improved adipocyte health and seems to be directly associated with the beneficial effects of exercise.

Liquid chromatography coupled to high-resolution mass spectrometry metabolomics: A useful tool for investigating tumor secretome based on a three-dimensional co-culture model.

Three-dimensional (3D) cell culture technologies, which more closely mimic the complex microenvironment of tissue, are being increasingly evaluated as a tool for the preclinical screening of clinically promising new molecules, and studying of tissue metabolism. Studies of metabolites released into the extracellular space (secretome) allow understanding the metabolic dynamics of tissues and changes caused by therapeutic interventions. Although quite advanced in the field of proteomics, studies on the secretome of low molecular weight metabolites (< 1500 Da) are still very scarce. We present an untargeted metabolomic protocol based on the hybrid technique of liquid chromatography coupled with high-resolution mass spectrometry for the analysis of low-molecular-weight metabolites released into the culture medium by 3D cultures and co-culture (secretome model). For that we analyzed HT-29 human colon carcinoma cells and 3T3-L1 preadipocytes in 3D-monoculture and 3D-co-culture. The putative identification of the metabolites indicated a sort of metabolites, among them arachidonic acid, glyceric acid, docosapentaenoic acid and beta-Alanine which are related to cancer and obesity. This protocol represents a possibility to list metabolites released in the extracellular environment in a comprehensive and untargeted manner, opening the way for the generation of metabolic hypotheses that will certainly contribute to the understanding of tissue metabolism, tissue-tissue interactions, and metabolic responses to the most varied interventions. Moreover, it brings the potential to determine novel pathways and accurately identify biomarkers in cancer and other diseases. The metabolites indicated in our study have a close relationship with the tumor microenvironment in accordance with the literature review.

Knee Osteoarthritis: Kinesiophobia and Isometric Strength of Quadriceps in Women.

Introduction: Osteoarthritis is a disease characterized by progressive wear and tear of the joint, with the knee being the most affected region. These patients have reduced mobility and mobility, among other symptoms. Thus, it is necessary to know the variables that influence the ability to walk. Objective: To analyze how much the gait capacity, in the performance of the six-minute walk test, can be influenced by the maximum isometric strength of the quadriceps or by kinesiophobia in women with knee osteoarthritis. Materials and Methods: This is a cross-sectional study with a sample of 49 women diagnosed with osteoarthritis. The evaluation was carried out in a single moment. Variables studied isometric quadriceps strength, level of fear of movement (kinesiophobia), and ability to walk. Simple linear regression analyzes were performed, with gait ability as the dependent variable and maximum isometric strength and kinesiophobia as independent. Data were presented with mean and standard deviation and were analyzed by the SPSS Statistic 22.0 software, considering p < 0.05 as significant. Results: The maximum isometric strength presents a significant difference, directly interfering with the gait ability; as kinesiophobia does not show a statistically significant difference, it does not directly interfere with the ability to walk. Conclusion: Maximal quadriceps isometric strength directly interferes with gait ability in women with knee osteoarthritis, thus suggesting the inclusion of this strategy in treatment programs for this population.

Comparison of Climacteric Symptoms, Quality of Life, and Self-Care Attitudes before and during the COVID-19 Pandemic.

OBJECTIVES: This study aimed to compare the climacteric symptoms, quality of life indices, and self-care attitudes in women before and during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study was conducted between January 2020 and September 2021. The sample consisted of 342 climacteric women who were divided into two groups: before the pandemic (BP group; n = 62) and during the pandemic (DP group; n = 280). The Menopause Rating Scale and Women's Health Questionnaire were used to measure the health-related quality of life and degree of climacteric symptoms reported by women. RESULTS: During the COVID-19 pandemic, women were able to decrease their somatic symptoms derived from the climacteric period (BP group: 7.84 ± 4.46, DP group: 5.94 ± 9.20; P = 0.003). CONCLUSIONS: There was no worsening in the self-reported symptoms, quality of life, and self-care attitudes of climacteric women because of the COVID-19 pandemic. Moreover, only somatic symptoms decreased during the pandemic.
