Prognostic Impact of AGR3 Protein Expression in Breast Cancer: A Systematic Review and Meta-analysis.

OBJECTIVE: To investigate the clinicopathological significance and prognosis of the expression of the anterior gradient 3 (AGR3) protein in women with breast cancer. DATA SOURCES: The PubMed, CINAHL, EMBASE, Scopus, and Web of Science databases were searched for studies published in English and without restrictions regarding the year of publication. The search terms were: breast cancer AND anterior gradient 3 OR AGR3 expression. STUDY SELECTION: We included observational or interventional studies, studies on AGR3 protein expression by immunohistochemistry, and studies on invasive breast cancer. Case reports, studies with animals, and reviews were excluded. In total, 4 studies were included, containing 713 cases of breast cancer. DATA COLLECTION: Data were extracted on clinicopathological characteristics and survival. A meta-analysis of the prevalence of AGR3 expression was performed according to the clinicopathological characteristics, hazard ratios (HRs), and overall survival and disease-free survival. DATA SYNTHESIS: The expression of AGR3 was found in 62% of the cases, and it was associated with histological grade II, positivity of estrogen and progesterone receptors, low expression of ki67, recurrence or distant metastasis, and lumen subtypes. In patients with low and intermediate histological grades, AGR3 expression was associated with worse overall survival (HR: 2.39; 95% confidence interval [95%CI]: 0.628-4.159; p = 0.008) and worse disease-free survival (HR: 3.856; 95%CI: 1.026-6.686; p = 0.008). CONCLUSION: The AGR3 protein may be a biomarker for the early detection of breast cancer and predict prognosis in luminal subtypes. In addition, in patients with low and intermediate histological grades, AGR3 protein expression may indicate an unfavorable prognosis in relation to survival.

Indicators of Eating Disorders in Sexually Abused Brazilian Adolescents: Family and School Contexts.

Eating disorders, characterized by abnormal eating behaviors, are among a wide variety of psychiatric conditions that mainly affect children and adolescents. These disorders have a multifactorial origin and can be associated with restrictive diets, negative feelings, harmful family relationships, and post-traumatic stress. Thus, this study's objective was to evaluate the association between indicators of eating disorders and family and school contexts in Brazilian adolescents who previously experienced sexual abuse and examine the findings based on sex. National School Health Survey data were utilized. Among 102,301 students between 11 and 19 years of age, 4124 reported having experienced sexual abuse and were included in this study. Self-report questionnaires were used to assess participants' health status and the presence of risk behaviors, which were examined through multivariate analysis using a Poisson regression model. The results indicated positive relationships between self-induced vomiting, laxative misuse, and other purgative methods and infrequent meals with family, hunger, and the presence of violence in students' daily lives, regardless of sex (p < 0.05). In addition, body dissatisfaction and negative feelings about one's body were associated with having been bullied or teased by schoolmates for both sexes (p < 0.05). Distant relationships with parents were associated with purgative methods and body dissatisfaction among female students (p < 0.05). In conclusion, body dissatisfaction, negative feelings about one's body, laxative misuse, self-induced vomiting, and purgative methods were found to be associated with factors in family and school contexts such as hunger, infrequent meals with family, family violence, distant relationships with parents, and bullying at school in adolescents who have previously experienced sexual abuse.

Relationship between depression and quality of life among students: a systematic review and meta-analysis.

The objectives of this systematic review were to estimate the prevalence of depression and to identify the relationship between depression and quality of life (QOL) among high school and university students. Literature search was performed in the Scopus, Embase, PubMed, Scielo, CINAHL and Web of Science databases, following the PRISMA methodology. The results were presented through descriptive approaches and meta-analysis. Thirty-six studies met the eligibility criteria, and twenty-six were included in the meta-analysis. The prevalence of depressive symptoms was 27% (95% CI 0.21-0.33) among students, being high school and university students was 25% (95% CI 0.14-0.37) and 27% (95% CI 0.20-0.34), respectively, and most studies have shown that depression was associated with low QOL. Among the limitations of the study is the difficulty of generalizing the results found, considering the large sample of health students. New studies should be conducted considering the severity, duration, and patterns of depressive symptoms in high school and university students, to better understand the relationship between depression and QOL.

Prevalence and Risk Factors of Musculoskeletal Disorders in Basketball Players: Systematic Review and Meta-Analysis.

Musculoskeletal disorders characteristically induce pain and limitations in mobility, ability, and overall functioning. In athletes, including basketball players, disorders such as back pain, postural changes, and spinal injuries are common. This systematic review aimed to evaluate the prevalence of back pain and musculoskeletal disorders in basketball players and ascertain the associated factors. Methods: The Embase, PubMed, and Scopus databases were searched for studies published in English without a time limit. Using STATA, meta-analyses were performed to estimate the prevalence of pain and musculoskeletal disorders of the back and spine. Results: Of the 4135 articles identified, 33 studies were included in this review, with 27 studies included in the meta-analysis. Of these, 21 were used for the meta-analysis of back pain, 6 articles were used for the meta-analysis of spinal injury, and 2 studies were used for the meta-analysis of postural changes. The overall prevalence of back pain was 43% [95% CI, -1% to 88%]; of these, the prevalence of neck pain was 36% [95% CI, 22-50%], the prevalence of back pain was 16% [95% CI, 4-28%], the prevalence of low back pain was 26% [95% CI, 16-37%], the prevalence of thoracic spine pain was 6% [95% CI, 3-9%]. The combined prevalence of spinal injury and spondylolysis was 10% [95% CI, 4-15%], with a prevalence of spondylolysis of 14% [95% CI, 0.1-27%]. The combined prevalence of hyperkyphosis and hyperlordosis was 30% [95% CI, 9-51%]. In conclusion, we found a high prevalence of neck pain, followed by low back pain and back pain, in basketball players. Thus, prevention programs are important to improve health and sports performance.

Sedentary behavior, physical inactivity, abdominal obesity and obesity in adults and older adults: A systematic review and meta-analysis.

BACKGROUND: Sedentary behavior and physical inactivity may increase the risk of obesity. This systematic review and meta-analysis aimed to investigate: i) the prevalence/incidence of sedentary behavior and physical inactivity, ii) the association of sedentary behavior and physical inactivity with obesity, and iii) the objective and subjective measures, diagnostic criteria, and cut-off points to estimate sedentary behavior and physical inactivity in adults and older adults with obesity. METHODS: We conducted a systematic review and meta-analysis in PubMed, Scielo, Lilacs, and Cochrane Library databases. A meta-analysis of a random-effects model was performed to estimate the combined prevalence of sedentary behavior and physical inactivity and their association with obesity. RESULTS: Twenty-three studies involving 638,000 adults and older adults were included in the systematic review. A meta-analysis was conducted with 111,851 individuals with obesity. The combined prevalence of sedentary behavior was 31% (95% CI, 23-41%), and physical inactivity was 43% (95% CI, 31-55%). Significant associations between obesity and sedentary behavior (OR 1.45, 95% CI, 1.21-1.75) and physical inactivity (OR 1.52, 95% CI, 1.23-1.87) were found. Nine studies have used objective measures to assess physical activity levels, such as accelerometers and pedometers, whereas fourteen applied subjective methods and self-reported questionnaires. CONCLUSIONS: As expected, we found elevated rates of sedentary behavior and physical inactivity in individuals with obesity and a positive risk association. The wide range of objective and subjective measures, methods and cut-offs resulted in great variations of physical inactivity and sedentary behavior estimates.

Association between multimorbidity and hospitalization in older adults: systematic review and meta-analysis.

BACKGROUND: Multimorbidity is defined as the presence of multiple chronic conditions in the same individual. Multimorbidity is more prevalent in older adults and can lead to several adverse health outcomes. METHODS: We systematically reviewed evidence from observational studies to verify the association between multimorbidity and hospitalization in older adults. Furthermore, we also aimed to identify whether it changes according to gender, advanced age, institutionalization, and wealth of the country of residence. We searched the PubMed, Embase and Scopus databases from December 2020 to April 2021. The analysed outcomes were as follows: hospitalization, length of stay and hospital readmission. RESULTS: Of the 6,948 studies identified in the databases, 33 were included in this review. From the meta-analysis results, it was found that multimorbidity, regardless of the country's wealth, was linked to hospitalization in older adults (OR = 2.52, CI 95% = 1.87-3.38). Both definitions of multimorbidity, ≥2 (OR = 2.35, 95% CI = 1.34-4.12) and ≥3 morbidities (OR = 2.52, 95% CI = 1.87-3.38), were associated with hospitalization. Regardless of gender, multimorbidity was associated with hospitalization (OR = 1.98, 95% CI = 1.67-2.34) and with readmission (OR = 1.07, 95% CI = 1.04-1.09). However, it was not possible to verify the association between multimorbidity and length of stay. CONCLUSIONS: Multimorbidity was linked to a higher hospitalization risk, and this risk was not affected by the country's wealth and patient's gender. Multimorbidity was also linked to a higher hospital readmission rate in older adults. PROSPERO Registration (Registration number: CRD42021229328).

Antitumor effects of oleandrin in different types of cancers: Systematic review.

Oleandrin, a cardiac glycoside isolated from the leaves of Nerium oleander, has known effects on the heart. Evidence from recent studies have highlighted its potential for anticancer properties. Therefore, we aimed to investigate the effects of oleandrin on cancer cell proliferation, viability and apoptosis in vitro and in vivo. We performed a systematic search in six electronic databases up to Jan 2022. We extracted information about the effects of oleandrin on cell proliferation, cell viability, apoptosis and/or cell cycle arrest in in vitro studies, and the effects on tumor size and volume in animal experimental models. We have retrieved 775 scientific studies. 14 studies met the inclusion criteria. They investigated the effects of oleandrin on breast, lung, pancreatic, colon, prostate, colorectal, oral, ovarian, glioma, melanoma, glioblastoma, osteosarcoma, and histiocytic lymphoma cancers. Overall, in vitro studies demonstrated that oleandrin was able to inhibit cell proliferation, decrease cell viability, and induce apoptosis and/or cell cycle arrest. In addition, oleandrin had an effect on reducing mean tumor size and volume in animal studies. Oleandrin, as a cytotoxic agent, demonstrated antitumor effects in different types of cancers, however important clinical limitations remain a concern. These results encourage future studies to verify the applicability of oleandrin in antineoplastic therapeutic protocols human and veterinary medicine, the investigation of antimetastatic properties, as well as the potential increase in patient survival and the decrease of tumor markers.

Antitumor Properties of Curcumin in Breast Cancer Based on Preclinical Studies: A Systematic Review.

Breast cancer is one of the most common neoplasms among women. Anticancer strategies using natural formulations and phytotherapies are promising antitumor treatment alternatives. This review assesses the antitumor effects of curcumin on breast cancer reported in preclinical in vitro and in vivo animal models. We used five databases to search for preclinical studies published up to May 2021. The assessments included the effects of curcumin on the proliferation, viability, and apoptosis of breast cancer cell lineages and on tumor volume. In total, 60 articles met the inclusion criteria. Curcumin administered at different concentrations and via different routes of administration inhibited proliferation, decreased viability, and induced apoptosis in human and animal breast cancer cells. Nanoparticle formulations of curcumin administered orally, via implant, and intraperitoneally reduced the tumor volume of human and murine mammary cells in vivo. Moreover, curcumin nanoformulations exert positive effects on tumor growth inhibition in animal models of breast cancer. Further randomized clinical trials are warranted to assess the efficacy and safety of curcumin formulations for clinical use.

Barriers to high school and university students' physical activity: A systematic review.

Physical inactivity commonly occurs throughout one's life, particularly during adolescence and young adulthood. Multiple factors can negatively influence participation in physical activity, but there has been no review examining the barriers to physical activity among high school and university students. Therefore, the aim of this systematic review was to summarize evidence of barriers to the practice of physical activity among high school and university students. The literature search was conducted without time limits using five databases, including CINAHL, Cochrane Library, Embase, PubMed, and Scopus. In total, 59 studies (37 with high school students [n = 22,908] and 22 with university students [n = 15,411]) were included. The main barriers identified in high school and university students were lack of time, lack of motivation, and lack of accessible places. These findings may be useful in designing and implementing evidence-informed interventions and programs for physical activity promotion in students.

Gastroschisis: a systematic review of diagnosis, prognosis and treatment.

OBJECTIVES: The present systematic review aims to investigate the diagnosis, prognosis, delivery assistance, pregnancy results and postnatal management in gastroschisis. STUDY DESIGN: The following data sources were evaluated: The CINAHL, Embase and MEDLINE/PubMed databases were searched, observational and intervention studies published over the past 20 years. The quality of the studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). RESULTS: A total of 3770 infants diagnosed with gastroschisis were included (44 studies); 1534 fetuses were classified as simple gastroschisis and 288 as complex gastroschisis. Intrauterine fetal demise occurred in 0.47% and elective termination occurred in 0.13%. Preterm delivery occurred in 23.23% and intrauterine growth restriction in 4.43%. Cesarean section delivery was performed in 54.6%. Neonatal survival was 91.29%. The main neonatal complications were: sepsis (11.78%), necrotizing enterocolitis (2.33%), short bowel syndrome (1.37%), bowel obstruction (0.79%), and volvulus (0.23%). Immediate surgical repair was performed in 80.1% with primary closure in 69%. The average to oral feeding was 33 (range: 11-124.5) days. Average hospital duration was 38 days and 89 days in neonates with simple and complex grastroschisis, respectively. CONCLUSIONS: The present systematic review provides scientific data for counseling families with fetal gastroschisis.

Prognostic Role of PD-L1 Expression in Invasive Breast Cancer: A Systematic Review and Meta-Analysis.

Programmed death ligand 1 (PD-L1) has been investigated in various types of cancer; however, the role of PD-L1 expression in breast cancer remains controversial. We performed a systematic review and meta-analysis to assess the association of PD-L1 expression with clinicopathological variables, overall survival (OS), and disease-free survival (DFS) in invasive breast cancer. A total of 965 articles were included from CINAHL, Embase, PubMed, and Scopus databases. Of these, 22 studies encompassing 6468 cases of invasive breast cancer were included in the systematic review, and 15 articles were included in the meta-analysis. PD-L1 expression was associated with age ≥ 50 years, lymph node status-negative, progesterone receptor-negative, Ki67 ≥ 20%, and human epidermal growth factor receptor 2 (HER2)-negative. PD-L1 positivity was associated with worse OS (hazard ratio, HR, 2.39; 95% confidence interval, CI, 1.26-3.52; p =< 0.000); however, there was no significant improvement in DFS (HR 0.17; 95% CI -0.12-0.46; p =< 0.252). PD-L1 positivity was significantly associated with the clinicopathological characteristics of favorable and unfavorable prognoses. However, the final clinical outcome was associated with lower OS and had no significant association with DFS.

Psychosocial Aspects of Gestational Grief in Women Undergoing Infertility Treatment: A Systematic Review of Qualitative and Quantitative Evidence.

Women undergoing assisted reproduction treatment without being able to become pregnant, and experiencing pregnancy loss after assisted reproduction, are triggering factors for prolonged grief and mourning. This review aims to investigate the psychosocial aspects of gestational grief among women who have undergone infertility treatment. We searched the databases of MEDLINE/PubMed, EMBASE, CINAHL, Scopus, ScienceDirect, and Lilacs for works published up to 5 March 2021. The outcomes analyzed were negative and positive psychosocial responses to gestational grief among women suffering from infertility and undergoing assisted human reproduction treatment. Eleven studies were included, which yielded 316 women experiencing infertility who were undergoing treatment. The most frequently reported negative psychosocial manifestations of grief response were depression (6/11, 54.5%), despair or loss of hope/guilt/anger (5/11, 45.5%), anxiety (4/11, 36.4%), frustration (3/11, 27.3%), and anguish/shock/suicidal thoughts/isolation (2/11, 18.2%). Positive psychosocial manifestations included the hope of becoming pregnant (4/6, 66.6%) and acceptance of infertility after attempting infertility treatment (2/6, 33.3%). We identified several negative and positive psychosocial responses to gestational grief in women experiencing infertility. Psychological support before, during, and after assisted human reproduction treatment is crucial for the management of psychosocial aspects that characterize the grief process of women experiencing infertility who become pregnant and who lose their pregnancy. Our results may help raise awareness of the area of grief among infertile women and promote policy development for the mental health of bereaved women.

Ultrasound Markers for Complex Gastroschisis: A Systematic Review and Meta-Analysis.

Although gastroschisis is often diagnosed by prenatal ultrasound, there is still a gap in the literature about which prenatal ultrasound markers can predict complex gastroschisis. This systematic review and meta-analysis aimed to investigate the ultrasound markers that characterize complex gastroschisis. A systematic review of the literature was conducted according to the guidelines of PRISMA. The protocol was registered (PROSPERO ID CRD42020211685). Meta-analysis was displayed graphically on Forest plots, which estimate prevalence rates and risk ratios, with 95% confidence intervals, using STATA version 15.0. The combined prevalence of intestinal complications in fetuses with complex gastroschisis was 27.0%, with a higher prevalence of atresia (about 48%), followed by necrosis (about 25%). The prevalence of deaths in newborns with complex gastroschisis was 15.0%. The predictive ultrasound markers for complex gastroschisis were intraabdominal bowel dilatation (IABD) (RR 3.01, 95% CI 2.22 to 4.07; I2 = 15.7%), extra-abdominal bowel dilatation (EABD) (RR 1.55, 95% CI 1.01 to 2.39; I2 = 77.1%), and polyhydramnios (RR 3.81, 95% CI 2.09 to 6.95; I2 = 0.0%). This review identified that IABD, EABD, and polyhydramnios were considered predictive ultrasound markers for complex gastroschisis. However, evidence regarding gestational age at the time of diagnosis is needed.

Reduction in Pain and Pain Intensity with Nonpharmacological Treatment in Severely Obese Patients: A Randomized Clinical Trial.

The objective of this study was to analyze the effectiveness of two nonpharmacological interventions-traditional Brazilian diet (DieTBra), and extra-virgin olive oil (EVOO)-in terms of the reduction in pain and pain intensity in individuals with severe obesity. We conducted a 12-week parallel randomized clinical trial with 149 individuals (body mass index (BMI) ≥ 35 kg/m2) who were randomized into three groups: supplementation with EVOO (n = 50), DieTBra (n = 49), and EVOO + DieTBra (n = 50). Of the total, 133 individuals with a mean BMI of 46.04 kg/m2 completed the study. By the end of the follow-up, there was a reduction in severe pain in the EVOO + DieTBra group (p = 0.003). There was a significant reduction in severe pain in the EVOO + DieTBra group (-22.7%); pain in the wrist and hand (-14.1%), upper back (-26.9%), and knees (-18.4%) in the DieTBra group; and reduction in hip pain (-11.1%) with EVOO consumption. We conclude that EVOO and DieTBra, either alone or in combination, are effective interventions to reduce pain intensity and pain in different regions in individuals with severe obesity, and have great potential for clinical application.

Pain in Hemodialysis Patients: Prevalence, Intensity, Location, and Functional Interference in Daily Activities.

Although pain is a frequent complaint of patients with chronic kidney disease who undergo hemodialysis, few studies have assessed the functional interference of pain in activities of daily living (ADLs). Hence, the aim of this study was to evaluate the prevalence, location, intensity, and functional interference of pain in ADLs of chronic kidney disease patients undergoing hemodialysis and to estimate the association of specific pain sites with severe functional interference by pain in ADLs. This cross-sectional study included patients with chronic kidney disease undergoing hemodialysis. The prevalence, intensity, and functional interference of pain in ADLs were assessed using the brief pain inventory. Poisson regression was used to calculate the prevalence ratio. A total of 65 patients participated in the study. The overall prevalence of pain was 89.23%; the prevalence of headache was 18.46% and that of pain in the trunk was 55.38%, upper limbs was 35.38%, and lower limbs was 60.00%. The prevalence of moderate and severe pain at the time of hemodialysis was 13.85% and 21.54%, respectively. A high prevalence of severe functional interference of pain in general activity (61.54%), mobility (56.92%), and disposition (55.38%) was observed. Pain is a frequent complaint in patients undergoing hemodialysis, mainly musculoskeletal and intradialytic, and it interferes with ADLs and incapacitates the patient. Pain was highly prevalent in the upper and lower limbs and the trunk. Furthermore, a higher prevalence of severe pain at the time of hemodialysis and functional interference of pain, mainly in general activity, mobility, and disposition, were observed.

Prevalence of sexual abuse and its association with health-risk behaviors among Brazilian adolescents: A populational study.

BACKGROUND: Analysis of sexual abuse has usually been neglected in research at developing countries despite its everlasting consequences. This study examined the prevalence of sexual abuse among Brazilian adolescents according to data from the National School Health Survey (PeNSE) and analyzed it based on Brazilian regions, sociodemographic aspects, health information, and health-risk behaviors among Brazilian adolescents who reported having experienced sexual abuse previously. PARTICIPANTS AND SETTING: The PeNSE data were utilized, and the sample included 102,072 students from all over Brazil, aged between 11 and 19 years. METHODS: Data were collected by questionnaires and were analyzed by multivariate analysis using the Poisson regression model. RESULTS: The results denoted a relation between sexual abuse, social determinants of health variables (i.e., black, indigenous, and mixed skin color/ethnicity; Brazilian region public school, age between 15 and 18 years, and low education level of the mother), and health-risk behaviors (i.e., early sexual intercourse, having multiple sexual partners, unprotected sexual intercourse, use of tobacco, alcohol, and illicit drugs). CONCLUSION: Therefore, reports of sexual abuse are associated with risky behaviors. Given these findings, targeted interventions on sexual abuse are essential for the health of adolescents and the prevention of risky behaviors, and can also facilitate programs to prevent sexual abuse.

Poor Sleep Quality and Daytime Sleepiness in Health Professionals: Prevalence and Associated Factors.

This study aimed to examine the prevalence rates of poor quality sleep and daytime sleepiness in health professionals and their association with socioeconomic, lifestyle, and anthropometric factors and psychosocial work conditions. This cross-sectional study was performed with health professionals from various public and private hospitals in Rio Verde, Goiás, Brazil. Daytime sleepiness and sleep quality were assessed using the Epworth Sleepiness Scale and the Pittsburgh Sleep Quality Index, respectively. The variables were analyzed using multiple hierarchical Poisson regression in the statistical package Stata version 13.0. A total of 244 health professionals participated in this study (women, 78.28%). The rates of abnormal daytime sleepiness and poor sleep quality were 50.41% (n = 123) and 55.74% (n = 136), respectively. Reduced physical activity was associated with poor sleep quality (prevalence ratio (PR) = 1.32; 95% confidence interval (CI) 1.02-1.70, p = 0.035). Age between 20 and 29 years (PR = 2.59; 95% CI 1.37-4.91, p = 0.021) and 30 and 49 years (PR = 2.09; 95% CI 1.12-3.91, p = 0.021), as well as excessive alcohol consumption (PR = 1.29; 95% CI 1.01-1.66, p = 0.048), were risk factors for daytime sleepiness. Conversely, adequate bodyweight (PR = 0.52; 95% CI 0.33-0.82, p = 0.005) was considered a protective factor. The present findings suggest high rates of abnormal daytime sleepiness and poor sleep quality among healthcare professionals. We emphasize the importance of physical activity, adequate weight, and healthy habits for better quality sleep and reduced daytime sleepiness.

Pain in Patients With Chronic Kidney Disease Undergoing Hemodialysis: A Systematic Review.

AIMS: To assess the presence of pain, its location, intensity, and effects on the daily activities of patients with chronic kidney disease (CKD) undergoing hemodialysis (HD). PARTICIPANTS/SUBJECTS: Patients with chronic kidney disease (CKD) undergoing hemodialysis (HD). DESIGN: A systematic review. METHODS: We carried out search for articles published until December 2020, including publications in Portuguese, English, and Spanish during the past 15 years (2005-2020), using the Embase, SciELO, PubMed, and Web of Science databases. The following information was collected: type of pain, pain treatment, pain assessment instrument, prevalence of pain, location, and influence of pain on quality of life. RESULTS: Twenty-five studies were selected for a systematic review. These studies involved a total of 98,162 adult and elderly patients with CKD who were undergoing HD. There was a high prevalence of pain in patients with CKD on HD. The most frequent sites of pain were the head, back, bones, chest, and the upper and lower limbs. The presence of acute, chronic, neuropathic pain, and myalgia was also reported in the studies. In addition, there was a higher frequency of moderate and severe pain, which influenced daily activities, the ability to walk, mood, relationships with other people, sleep, and work in patients on dialysis. CONCLUSIONS: The analyzed studies suggest that acute and chronic pain is a prevalent complaint in adults and elderly patients undergoing HD. There was a higher frequency of moderate and severe pain in different parts of the body, and pain interfered with everyday activities.

Narrative review of the influence of high-intensity interval training on adolescents' bone health: commentary and perspectives.

Although several benefits have been associated to high-intensity interval training (HIIT), there is a lack of clarity on the HIIT effects in adolescents, especially on bone health outcomes. To address this gap, our research aimed to perform a systematic review, which focus on the influence of HIIT on adolescents' bone health. Our search strategy was conducted on three databases (PubMed, SCOPUS, and Embase). For our review, we included articles with the following characteristics: (I) sample consisting of adolescents (10-19 years old), (II) HIIT interventions; and (III) assessment of bone health outcomes. Longitudinal and clinical trials studies with no language and year of publications restrictions were eligible to be included. A total of 63 eligible studies were identified. After removing the duplicates and screening the titles and abstracts, six articles remained to be read in full text. However, none of the articles met our criteria. Studies in which no article meets the eligibility criteria are also essential and need to be shared with the academic community because it may stimulate appropriate future investigations in this field. This lack in the review results highlights the need for further epidemiological research focusing on this topic, including high quality, large scale, and longitudinal studies, as well as randomized controlled trials to confirm or refute efficacy.
