ABSTRACT
INTRODUCTION: Thalidomide is an immunomodulatory drug and first choice in the treatment of erythema nodosum leprosum. Given its teratogenic potential, it is essential that an effective contraceptive method is used, especially a long-acting reversible contraceptive (LARC) method. The subdermal etonogestrel (ENG)-releasing implant is an adequate method due to the high effectiveness and long-term use. However, interaction between thalidomide and ENG has not been well documented. Concern arises because thalidomide interacts with cytochrome P450 (CYP450) enzymes that metabolize sexual steroids. AIM: We aimed to study the effectiveness and safety of the ENG-implant in a thalidomide user. METHODS: Case report of a sexually active 21-year-old patient with both Hansen's disease and leprosy reaction type 2 treated with thalidomide requiring effective contraception. Follow-up was up to 36 months after implant placement. RESULTS: Contraception with ENG-implant was effective and safe, based on clinical parameters (reduction of menstrual flow and cervical mucus thickening) and laboratory parameters (gonadotropins and sexual steroids). CONCLUSION: To the best of our knowledge, this is the first case reported which presents a patient in simultaneous use of thalidomide and ENG-implant. Although this case report preliminary supports effectiveness and safety of ENG-implant as a contraceptive option in women using thalidomide, rigorous drug-drug interaction research is needed to better characterize the interaction between thalidomide and the ENG-implant.

Estrogen modulates platelet activation and aggregation, and it increases the levels of the von Willebrand factor, factors II, VII, VIII, and X, and of fibrinogen, all of which increase the risk for thromboembolism. We report the case of a 59-year-old woman, postmenopausal for 4 years, not using hormone replacement therapy, who was admitted into the emergency room with shortness of breath and increased abdominal volume. After physical examination and imaging and biochemical tests, she was diagnosed with pulmonary thromboembolism and a large left adnexal tumor. The patient was promptly received full anticoagulation therapy for the pulmonary thromboembolism. High levels of estradiol (810.4 pg/mL), anti-Mullerian hormone (16.39 ng/mL), inhibin (11250 pg/mL), and suppressed FSH (<0.16 IU/L) led to a suspicion of granulosa-cell tumor. After clinical stabilization, she underwent to an exploratory laparotomy with total hysterectomy and bilateral adnexectomy to treat the pelvic tumor. Pathologic report confirmed a granulosa-cell tumor.

Prolactin (PRL) acts stimulating the mammary glands development, and its deregulation has been associated to the emergence of several types of tumors, including breast cancer. Breast cancer represents the most prevalent malignancy in women, and the second cause of death in several countries. This tumor can be arise due to several molecular alterations, among them PRL has been the object of increasing interest from researchers worldwide. OBJECTIVE: To assess the association between elevated levels of plasma prolactin and breast cancer development. METHODS: A total of 158 studies were found in search databases (48 from PubMed, 69 from Scopus, 88 from Cochrane, 25 from Embase and 10 retrieved from the gray literature) after removing duplicates. Of these, 104 studies were excluded after title and abstract reading, and 54 studies were then read in full, of which only 14 were selected for this review because they had evaluated the association between PRL and breast cancer. Meta-analysis was carried out using the relative risk (RR), mean and standard deviation, confidence interval (95% CI), and the total number of patients for each study. Fixed- and random-effect models were used as applicable and, for the analysis. RESULTS: The meta-analysis showed a positive association between elevated levels of PRL and breast cancer occurrence (RR 1.26; 95%CI 1.15-1.37). Additionally, the patient sub-group analyses showed a positive association between PRL and invasive breast cancer (1.42; 1.24-1.60), ER+/PR+ (1.49; 1.23-1.75), and post-menopausal status (1.29; 1.16-1.43). CONCLUSION: The results showed a positive association between plasma prolactin levels and breast cancer, especially in women with ER+/PR + tumors, of post-menopausal age and those with invasive cancer.

BACKGROUND: Women with polycystic ovary syndrome (PCOS) are at an elevated risk of endometrial cancer, which may be associated with the continuous proliferative state caused by the interaction between hormones and metabolic factors. OBJECTIVE: To investigate the impact of hormones and metabolic factors in the proliferation and death of endometrium during the proliferative phase. METHODS: Cross-sectional study with 11 women with PCOS and eight normal-cycling non-PCOS controls at the Federal University of the State of Rio de Janeiro from February 2011 to June 2019. Clinical, biochemical, and hormonal data were collected to analyze their influence on the expression of biomarkers related to the endometrial tissue breakdown. Hysteroscopy and endometrial biopsies were conducted, and the endometrial samples underwent immunohistochemistry for markers of apoptosis B-cell lymphoma 2 (BCL2), cleaved caspase-3 (CASP3), fas cell surface death receptor (FAS), FAS ligand (FASLG), BCL2 associated X (BAX), marker of proliferation Ki-67 (MKI67), and cell death using terminal deoxynucleotidyl transferase dUTP nick and labeling (TUNEL). RESULTS: CASP3 and TUNEL expressions were lower in both stroma and endometrium gland of PCOS women than in controls. MKI67 and homeostasis indexes (BCL2/BAX; FASLG/FAS) in the endometrium of the PCOS group were significantly higher. Body mass index (BMI) values were positively correlated with the expression of MKI67 and MKI67/TUNEL ratio in the endometrial stroma compartment. Fasting insulin levels were positively correlated with the expression of BCL2, and DHEA-S levels were negatively correlated with the expression of CASP3 of women with PCOS. CONCLUSION: BMI, insulin, and DHEA-S influence the endometrial homeostasis breakdown in PCOS in the endometrium stroma.

Objective: Evaluate histomorphometry of ectopic and eutopic endometrial tissues in receptor mice. Method: Eighteen female Balb/c were divided into 3 groups, 6 animals each: GI Control, no procedure; GII - Sham, animals that had the same procedures as GIII without receiving the ectopic endometrial implant. Instead, they received saline solution; GIII - endometriosis model, animals had surgical intervention with an ectopic endometrial implant. GI and GIII mice were treated with 17ß-estradiol, 100 µg/kg each. All animals were euthanized to collect uterine horns, which were fixed in 4% paraformaldehyde, embedded in paraffin, stained with Hematoxilin and Eosin and submitted to histomorphometric analyzes. Data underwent one-way ANOVA followed by Tukey's test. Results: Local tissue growth, showing important lesions and adhesions, as well as dark cysts were noticed. In GIII group, there was an increase in number of blood vessels and glands (GIII ≥ GI and GIII p > .001). Thickening of the GIII endometrial epithelial was also evident (GIII ≥ GI and GIII. p > .001). We also noticed an increase in the number of eosinophils (GIII (GIII ≥ GI and GIII. p > .001). Conclusion: Easy to perform model, capable of reproducing morphological endometriosis characteristics. From our findings, there was an increase of endometrial thickness as well as an increase in the eosinophils population.

BACKGROUND: The transition in the population pyramid is a reality in several locations around the world and projections of an increase in the older population in Brazil demonstrate the relevance of studies on factors that may interfere in the functionality and quality of life in this age group. Thus, the present study aims to assess depression levels and their relationship with sleep quality in institutionalized and community older adults. METHODS: This cross-sectional study included 220 older people of both sexes, divided into two groups, institutionalized older adults, and community older adults. The older adults were monitored by Community Health Agents (CHA), through identification of everyone in their micro area using a method of random name generation, based on geographic location. Due to the small number of institutionalized older adults, all residents in the institutions were recruited, according to the inclusion and exclusion criteria. The Geriatric Depression Scale (GDS-15) and Pittsburgh Sleep Quality Index (PSQI) were used to assess depression and sleep quality. RESULTS: Among the 220 older adults, 175 were community members and 45 were institutionalized. The survey revealed that institutionalized older adults had a higher percentage of severe depression compared to community dwelling older adults (p < 0.039). CONCLUSION: Older adults in the community present greater symptoms of depression and better sleep than institutionalized older adults. There was a direct association between sleep quality and depression. In our sample, being institutionalized and female positively influenced and feeling alone negatively influenced depressive symptoms.

OBJECTIVE: To assess cyclin D1 and PTEN immunoexpression in benign endometrial polyps (EPs) in asymptomatic postmenopausal women and its correlation with obesity. Methods: This was a cross-sectional study based on data from a sample of 52 patients diagnosed with EP between February 2018 and January 2019. The women included in this study were amenorrheal for at least 1 year and were asymptomatic (no postmenopausal bleeding). Obesity defined by body mass index (BMI) was investigated for correlation with Cyclin-D1 and PTEN gene expression (immunohistochemistry) in glandular and stromal compartments of polyps. Results: No significant differences among groups were identified in any clinical and epidemiological parameter (age, age of menopause, time since menopause, number of gestations, polyp size, leucocyte count, fasting blood glucose and basic pathologies), except for BMI. Body mass index did not alter PTEN or Cyclin D1 immunoexpression. Conclusion: Our study shows that obesity does not appear to be a relevant factor in the immunoexpression of PTEN and Cyclin D1 in benign EP, in either the stromal or glandular compartments.

BACKGROUND: Condom non-use among sexually active adolescents is a major cause of unintended pregnancy and sexually transmitted infections. In order to promote condom use, it is essential to understand factors associated with condom non-use. AIM: Our aim was to evaluate sex differences and associated factors of condom non-use based on the nationally representative Brazilian National School Health Survey. METHODS: The study participants were 100,962 adolescents 13-18 years old, 9th graders from both public and private schools throughout Brazil. The following factors were considered as explanatory group variables for the outcome of condom non-use among adolescents: school and health service, sexual behavior, substance use, and self-reported body and health perception. Poisson regression model was performed. RESULTS: Of the total students, 28% (n = 28,157) had had sexual intercourse at least once. (boys, 37.1%; girls, 19.5%). Of these, 69.2% had used condoms the last time they had intercourse (girls: 68%; boys: 69.9%). The variables associated with condom non-use for both sexes were not having accessed a health service or approached a health professional for health-related care; not having received pregnancy prevention counseling or guidance on AIDS or STI prevention at school; early sexual initiation; no additional contraception method; substance use; feeling alone; not being satisfied with their own body; feeling fat or thin; and poor self-reported health. The number of sexual partners was also associated with condom non-use; however, contrasting behavior was indicated between sexes. A higher number of sexual partners indicated less use of condoms among girls, while for boys, a higher number of sexual partners indicated higher condom use. CONCLUSION: High condom non-use appears to be associated with lack of health care access and sexual health education, poor sexual practices, substance use, and poor self-perception, indicating areas for health promotion programs.

BACKGROUND: To determine whether age is a barrier against acceptability of cervicovaginal self-sampling in screening for cervical cancer at two gynecology outpatient clinics. METHODS: This is a cross-sectional study involving 116 women over 21 years of age with an abnormal Pap smear. Clinical and laboratorial data were recorded in electronic files. Women received detailed self-collection instructions. After the self-sampling procedure (Evalyn Brush®), women were instructed to answer a questionnaire about vaginal self-sampling acceptability that consisted of seven multiple-choice items. The participants were divided into three age brackets: 21 to 29 years, 30 to 49 years, and 50 years and over. Chi-square, Fischer exact, Kolmogorov-Smirnov and Kruskal-Wallis tests were used. RESULTS: The analysis of the participants' perception of the procedure stratified according to age groups showed a decline in the fear of hurting oneself during the procedure as age increased. Most participants reported that it was very easy to understand how to use the self-sampling brush and that it was easy to use it. Most of them were neither embarrassed nor afraid of getting hurt during the procedure. The majority preferred self-sampling to collection by a healthcare professional. The main reason was practicality: the possibility of choosing the place and time for sampling. CONCLUSIONS: The participating women found self-collection simple to understand and easy to accept regardless of age. The younger women indicated more fear and discomfort in self-sampling, which points to the need for attraction strategies that are more appealing to the younger generations.

The current reference standard to check the position of a tubal sterilization microinsert device after its insertion is hysterosalpingography. The objective of this study was to evaluate the accuracy of 2-dimensional (2D) and 3-dimensional (3D) ultrasonography (US) in the positioning of the tubal sterilization microinsert for definitive contraception. We searched MEDLINE, Embase, Cochrane, and Scopus databases through October 2017. Selection criteria included studies that analyzed the accuracy of 2D or 3D US, or both, with respect to the positioning of the microinsert. Data were displayed as forest plots and a summary receiver operating characteristic curves. Values for sensitivity, specificity, and positive and negative likelihood ratios (LRs) were calculated. The pooled analysis produced sensitivity and specificity values for 2D US in the positioning of the microinsert of 0.88 (95% confidence interval [CI], 0.47-1.0) and 0.92 (95% CI, 0.88-0.95), respectively, with positive and negative LRs of 8.68 (95% CI, 1.63-46.1) and 0.35 (95% CI, 0.11-1.11), respectively. Three studies analyzed the performance of 3D US, showing sensitivity, specificity, and positive and negative LRs of 0.75 (95% CI, 0.35-0.97), 0.82 (95% CI, 0.77-0.87), 3.65 (95% CI, 2.31-5.75), and 0.46 (95% CI, 0.2-1.09). In conclusion, 2D and 3D US are methods that show good accuracy in tubal sterilization microinsert positioning.

The objective of this study was to evaluate the action of soy isoflavones and 17 beta estradiol on the extracellular matrix in the uterus and mammary gland of diabetic rats. Sixty adult female rats underwent ovariectomy, then randomized into seven groups of ten animals each: Non-diabetic: GI Sham control animals ovariectomized; and GII control ovariectomized that received propylene glycol vehicle. Diabetic: GIII Sham control diabetic animals ovariectomized; GIV ovariectomized diabetic animals receiving propylene glycol vehicle; GV diabetic ovariectomized animals treated with soy isoflavones (150 mg/kg by gavage); GVI ovariectomized diabetic rats treated with estrogen (17b-estradiol, 10 mg/kg, subcutaneously); GVII diabetic ovariectomized animals treated with soy isoflavones (150 mg/kg by gavage), and with estrogen (17b-estradiol, 10 mg/kg combination therapy). Treatments occurred during 30 consecutive days. After animals euthanasia, a portion of the uterus was immersed in liquid nitrogen for molecular biology analysis, the other portion of uterus and mammary glands were removed and processed for paraffin embedding. Soy isoflavones (GV) and 17b estradiol improved the production of compounds of extracellular matrix, such as small leucine-rich proteoglycans (SLRPs). The combination of both therapies had an additive effect in SLRPs expression. Soy isoflavones contribute to the uterine integrity of SLRPs of diabetic rats.

This study aimed to determine whether the ovaries synthesize estradiol (E2), testosterone (T), and androstenedione (A) after menopause. The first group (30 patients) underwent surgical menopause (SM) - their ovaries were removed due to a benign condition around the time of menopause. The second group (30 patients) consisted of patients with natural menopause (NM). The E2 median level was 10.0 pg/ml (CI ± 2.18) and 9.5 pg/ml (CI ± 1.63) in the NM and SM groups (p = .69), respectively. The median level of total T was 0.12 ng/ml (CI ± 0.01) and 0.11 ng/ml (CI ± 0.03) in NM and SM, respectively (p = .96). The median level of A was 783.85 pg/ml (CI ± 154.39) and 883.48 pg/dl (CI ± 201.03) in NM and SM, respectively (p = .57). The FAI (free androgen index) was 1.06 (CI ± 0.24) and 1.35 (CI ± 0.68) for NM and SM, respectively (p = .98). We concluded that 5-10 years after menopause the ovaries are no longer relevant for sex steroid synthesis.

OBJECTIVE: The selection of breast cancer patients as candidates for nipple-sparing mastectomy (NSM) is dependent on the preoperative detection of neoplastic involvement of the nipple-areola complex (NAC). This cross-sectional study was designed to evaluate the accuracy of preoperative breast MRI as a noninvasive method to predict neoplastic involvement of the nipple. MATERIALS AND METHODS: We included 165 female breast cancer patients with a surgical plan that included total mastectomy or breast conservation surgery with the removal of the NAC. All patients underwent MRI before surgery on a 1.5-T unit with a 4-channel in vivo dedicated surface breast coil. One radiologist who was blinded to the results of the histologic evaluations of the specimens evaluated the MRI studies. RESULTS: Of the 170 mastectomy specimens evaluated, 37 (21.8%) had neoplastic involvement of the NAC. The MRI findings of enhancement between the index lesion and the NAC and of nipple retraction were considered statistically significant predictors of nipple involvement in breast cancer patients (p < 0.01 and p = 0.01, respectively). The negative predictive value of the combination of these MRI findings was 83.3%. CONCLUSION: Breast MRI is a safe noninvasive method to preoperatively evaluate breast cancer patients eligible for NSM with a high specificity and a high negative predictive value when enhancement between the index lesion and the nipple and nipple retraction are analyzed.

The aim of this study was to quantify the sulfated glycosaminoglycans in the endometria of women with polycystic ovary syndrome (PCOS). Of the 18 patients recruited for this study, 10 patients with PCOS comprised the PCOS group (PCOSG), and eight patients with regular and ovulatory menstrual cycles comprised the control group (CG). The clinical, biochemical, morphological and endometrial data from both groups were analyzed. Biopsies were performed during the proliferative phase of the menstrual cycle for the CG and during the persistent proliferative phase for the PCOSG (all women were amenorrheic). In the PCOSG, there was a significant increase in the endometrial concentration levels of heparan sulfate (p = 0.03), but no difference in the concentrations of chondroitin sulfate was determined between the two groups (p = 0.77). Period of time without menstruation (p = 0.001) and body mass index (BMI) (p = 0.04) correlated directly and positively with heparan sulfate concentration. There was no association between heparan sulfate levels and basal insulin values (p = 0.08). High levels of endometrial heparan sulfate in women with PCOS indicate an interference with maternal-fetal recognition, which contributes to infertility; thus, endometrial heparan sulfate may be a predictive marker of future neoplasia risk.

OBJECTIVES: To evaluate the frequency of obesity in postmenopausal women and assess the potential effects of increased body mass index (BMI) on lipoprotein profile and on risk factors for arterial hypertension and diabetes. DESIGN: A cross-sectional study was conducted with 5027 postmenopausal Brazilian women. Analyses were performed of BMI and cardiovascular factors (systemic blood pressure [BP], total cholesterol, low-density lipoprotein, high-density lipoprotein [HDL-C], triglyceride, and fast glucose). The statistical analysis included the chi-square and Mann-Whitney tests. The significance level was set at 5%. RESULTS: Obesity (BMI >30) in our study characterized approximately 30% of the 5027 postmenopausal women. The comparison of patients with normal BMI and those with high BMI showed that high BMI had a significant negative effect on BP, as evidenced by the increased frequency of hypertension in overweight and obese patients (>25) (p < 0.001), that it also negatively and significantly affected triglyceride (p < 0.001) and fast glucose levels (p < 0.001), and that it was linked significantly to low levels of HDL-C. CONCLUSION: Our data showed the high frequency of obesity in our population and of the cardiovascular risks (glucose, systemic arterial hypertension, and low HDL-C) associated with high BMI.

Gender relations are a set of socially determined norms and rules that assign values, characteristics, and expectations to individuals based on their biological sex. These aspects also influence the clinician-patient relationship, since it has been for a long time based on cisheteronormativity. However, this attitude alienated the LGBTQIA+ community from health services. Global and specific gynecologic care needs to be offered to the LGBTQIA+ population, which has demands for sexual and reproductive health care. In this narrative review, we bring conceptual aspects, gender identity and expression, sexual history, screening for cancer and other care to the community.
ABSTRACT
BACKGROUND: Polycystic ovary syndrome (PCOS) is an endocrine disorder characterized by anovulation, hyperandrogenism, and polycystic ovarian morphology. Its etiology is uncertain and one of the hypotheses is that environmental factors, such as the bisphenol A (BPA) endocrine disruptor, may be involved. OBJECTIVE: To investigate the association between exposure to BPA and PCOS. SEARCH STRATEGY: Research was conducted focusing on studies published in English, Portuguese, and Spanish from January 2001 to March 2023 and available in Embase, Medline/PubMed, Rima, Lilacs, Scielo, Google academic, and SCI databases. SELECTION CRITERIA: Studies in humans that evaluated the association between exposure to BPA and a diagnosis of PCOS. DATA COLLECTION AND ANALYSIS: Following PRISMA guidelines, study characteristics and relevant data were extracted. MAIN RESULTS: Selection of 15 case-control and 7 cross-sectional studies with a total of 1682 PCOS patients. The studies were carried out in China, Poland, Turkey, Japan, Greece, Italy, the USA, Iran, Iraq, Egypt, India, Czechia, and Slovakia. A positive relationship between exposure to BPA and PCOS was described in19 studies (1391 [82.70%] of the PCOS patients). The fluids used in the studies were serum, urine, plasma, and follicular fluid. BPA was measured by ELISA and by chromatography (HPLC, HPLC-MS/MS, GC-MS, and GC-MS/MS). Diagnosis of PCOS used Rotterdam criteria in 15, NIH 1999 in 3, AE&PCOS Society in 2, similar to the Rotterdam criteria in 1, and criteria not informed in 1. Androgens were measured in 16 studies; in 12, hyperandrogenism was positively associated with BPA. BPA level was related to body mass index (BMI) in studies. In 15 studies independently of BMI, women with PCOS had higher BPA levels. Carbohydrate metabolism disorders were evaluated in 12 studies and in 6 a positive correlation was found with BPA levels. Lipid profile was evaluated in seven studies and in only one the correlation between lipid profile and BPA levels was present. CONCLUSIONS: Exposure to BPA is positively associated with PCOS, mainly with the hyperandrogenism.

INTRODUCTION: Advanced Glycation End-Products (AGEs) are a diverse group of highly reactive molecules that play a vital role in the development of neurodegenerative disorders, such as Parkinson's Disease (PD), leading to a decline in functional and cognitive capacity. The objective of this study was to assess the intake and quantification of AGEs in individuals with PD and to correlate them with their functional and cognitive abilities. METHODS: This was a cross-sectional study involving 20 PD patients and 20 non-PD individuals as the Control group (C). The autofluorescence reader was used to evaluate skin AGEs, while food recall was used to quantify AGEs consumed for three different days. The Montreal Cognitive Assessment, Short Physical Performance Battery, and handgrip tests were used. PD patients demonstrated greater impairment in functional capacity compared to the control group. RESULTS: Dominant Handgrip (p = 0.02) and motor performance, in the sit and stand test (p = 0.01) and Short Physical Performance Battery (SPPB) (p = 0.01) were inferior in PD patients than the control group. Although PD patients tended to consume less AGEs than the control group, AGE intake was negatively correlated with handgrip strength in individuals with PD (r = -0.59; p < 0.05). CONCLUSION: PD patients had lower strength and functional capacity, suggesting that the effects of AGEs might be exacerbated during chronic diseases like Parkinson's.

CONTEXT: Vehicle driving depends on the integration of motor, visual, and cognitive skills to respond appropriately to different situations that occur in traffic. OBJECTIVES: To analyze a model of performance predictor for braking time in the driving simulator, using a battery of tests divided by gender. METHODS: Selected were 100 male drivers with a mean age of 72.6 ± 5.7 years. Sociodemographic variables, braking time in the driving simulator, and motor, visual, and cognitive skills were evaluated. RESULTS: Comparing genders, men were older than women (p = 0.002) and had longer driving times (p = 0.001). Men had more strength in hand grip (p ≤ 0.001). In the linear regression analysis, the model explained 68 % of the braking time in men and 50.8 % in women. In the stepwise multiple linear regression analysis, the variable that remained in the model was the strength of the right plantar flexors, which explained 13 % of the braking time in women and men, and the cognitive variables explained 38.9 %. CONCLUSION: Sociodemographic, motor, visual, and cognitive variables, explained a substantial portion of the variability in braking time for both older women and men, the specific variables driving this performance differed between the sexes. For older women, factors such as muscle strength emerged as critical determinants of braking ability, highlighting the importance of physical health in maintaining driving skills. On the other hand, cognitive conditions emerged as the primary predictor of braking performance in older men, underscoring the role of mental acuity and decision-making processes in safe driving.

INTRODUCTION: An accurate assessment of balance problems is critical for decreasing the risk of falling in patients with Parkinson's Disease (PD). Reliable diagnostic tools such as Computerized Dynamic Posturography (CDP) are not feasible for the clinical setting. Therefore, the present study's aim was to assess the correlation between the clinical Balance Evaluation Systems Test (BESTest) and CDP. METHODS: 20 male older adults with Parkinson's Disease (PD) were included in this study. Participants first executed the Sit-To-Stand (STS), Step/Quick turn (SQT), and Step Up and Over (SUO) tests on a Balance Master® force platform, followed by a clinical balance evaluation using the BESTest. RESULTS: Four outcomes of the CDP were negatively correlated with one or more BESTest domains or total BESTest score: STS sway velocity was negatively correlated with the anticipatory postural adjustment (p = 0.02) and sensory orientation (p = 0.01) domains. SQT turn time was negatively correlated with biomechanical restriction (for turns to the left, p = 0.01, and right, p = 0.03, respectively), postural response (p = 0.01, p = 0.01), dynamic balance during gait (p = 0.007, p = 0.001), and total score (p = 0.02, p = 0.01). Step over time to the right in SUP was negatively correlated with the limits of the stability domain (p = 0.002) and total BESTest score (p = 0.020). SUO impact index was negatively correlated with the anticipatory postural adjustment domain (p = 0.01). CONCLUSION: This study shows that several BESTest domains are significantly correlated with CDP outcomes, demonstrating that the BESTest can be used as a more clinically feasible alternative for computerized posturography, without loss of information.
