Visceral Leishmaniasis with Hemophagocytic Syndrome in a patient infected by SARS-COV2: a case report
Introduction: Visceral leishmaniasis is a disease that determines a picture of immunosuppression in the patient after contact with infected sandflies. Secondary hemophagocytic syndrome, on the other hand, is an immune-mediated condition that develops after infections, neoplasms, or autoimmune diseases. COVID-19 has infected more than 130 million people and caused more than 2.6 million deaths worldwide. Immunosuppression triggered by COVID-19 can be an aggravating factor for latent infections. Report: This article reported the case of a patient, 37 years old, with a previous history of Severe Acute Respiratory Distress Syndrome due to SARS-COV-2, later diagnosed with Hemophagocytic Syndrome Secondary to Visceral Leishmaniasis. Conclusion: A SARS-CoV-2 pandemic has revealed cases of co-infection with visceral leishmaniasis, highlighting the need for case reports that contribute to the efficiency of diagnosing and treating patients with comorbidities, aiming for a favorable outcome in the clinical condition of the patients.

Nutritional status of schoolchildren living on a city in Brazilian Western Amazon: a cross-sectional study
Introduction: Childhood is an important phase in the formation of eating habits and in determining nutritional status. Objective: To analyze the association of socio-environmental characteristics and food consumption with the BMI of schoolchildren from the interior of the state of Amazonas, Brazil. Methods: Cross-sectional study carried out with schoolchildren, where information was collected on the birth of children, socioeconomic, anthropometric and food consumption characteristics. BMI for age served as the dependent variable, representing the evaluated outcome. After bivariate analysis, the variables that were associated with the outcome were selected for inclusion in a multivariable linear regression model. Results: The sample size corresponds to 97 children and their mothers. Most children were born with adequate weight (84.54%). A significant proportion of children were identified as being overweight (20.61%). The most consumed foods were fresh fruits (76.29%), followed by ultra-processed candies (56.7%) and vegetables (54.64%). Furthermore, more than half of the children consumed processed meats (50.52%) and sugary drinks (54.17%). Birth weight, gestational age, maternal BMI and family income showed a positive correlation with the students' BMI, while the absence of consumption of sugary drinks had a protective effect on the students' higher BMI. Conclusion: Higher birth weight, gestational age at birth, maternal BMI and family income were the main factors associated with higher BMI among students. Excess weight is a public health problem of moderate magnitude, reflecting the phase of nutrition transition in which the studied population is inserted.

Presence of symptoms after COVID-19 infection may explain the onset of female urinary incontinence: a cross-sectional study
Introduction: Coronavirus 2019 (COVID-19) is a multisystem disease that may affect lower urinary tract function. Objective: To determine if symptoms after COVID-19 infection may explain the onset of urinary incontinence (UI) in female survivors; to investigate the impacts of symptoms on the quality of life of incontinent women. Methods: Cross-sectional study carried out online which included Brazilian women aged 18 years or older who developed UI during or after the COVID-19 infection, and were infected during the last three-months before data collection. Participants answered a semi structured questionnaire with sociodemographic and clinical questions; and validated questionnaires to assess UI symptoms (3-Incontinence Questionnaire; and International Consultation on Incontinence Questionnaire – Short Form). Multiple linear and binary logistic regression analysis were performed. Results: 879 women were included. Symptoms after COVID-19 infection had a statistically significant impact on stress UI, urgency UI, and mixed UI, predicting adequately 75.7%, 84.6%, and 73.4% of the cases, respectively. Muscle pain impacted the quality of life of women with UI, explaining 6.3% of UI. Other symptoms (i.e., diarrhea, tingling, and difficulty in breathing) explained 5.2% of of the impact on quality of life in women with UI. The resence of a cough for more than three weeks impacted the quality of life of women with UI, explaining 2.7% of the outcome. Conclusion: Post-COVID-19 symptoms can explained the onset of UI. The presence of cough lasting more than 3 weeks impact the women’s quality of life.
Schizophyllan Polysaccharide from Schizophyllum commune demonstrates antinociceptive effect on preclinical models of acute pain
Introduction: Twenty-five to 29% of the global population experiences pain that motivates seeking emergency services. Objective: To evaluate the effect of schizophyllan glucan polysaccharide (SPG), an isolated β-(1→3),(1→6) glucan polysaccharide of Schizophyllum commune, in acute pain and neuromuscular performance on pre-clinical models. Methods: Male adult Swiss mice (20-30g, 60 days) were acclimated for a week in groups of 7 per cage before the experiment. SPG was administered, intraperitoneally, at doses of 0.1, 1.0, 3.0, 5.0, 10.0, 30.0, and 100.0 mg/Kg for the writhing test, and 1.0, 10.0, and 30.0 mg/Kg for the formalin and Rotarod tests, respectively. Statistical analysis was performed using one-way ANOVA, followed by the Duncan post hoc test, respectively, as appropriate (p<0.05). Results: Regarding the abdominal writhing test, SPG doses of 1.0, 5.0, 10.0, 30.0, and 100.0 mg/Kg promoted a significant reduction in writing of, respectively, 90.6%, 86.6%, 83.0%, 86.6%, and 76.2%. In the formalin test, the dose of SPG 30 mg/Kg reduced phase II nociception time by 78.0%. Relevant sedation was observed only to SPG 100 mg/Kg in the Rotarod test. Conclusion: SPG showed significant analgesic effects on acute inflammatory pain without causing concomitant central nervous system depression.

Cognitive impairment and depressive symptoms: effects on functional disability, falls, hospitalization, and polypharmacy in a longitudinal follow-up
Introduction: The ageing process is associated with a higher prevalence of depression and cognitive impairment, negatively affecting health. Objective: Analyse the effects of cognitive impairment and depressive symptoms on the risk of functional disability, falls, hospitalisation, and polypharmacy in a two-year follow-up. Methods: Longitudinal study, developed with 200 participants over 45 years old from primary healthcare centres in Três Lagoas, Mato Grosso do Sul, Brazil. The participants were initially evaluated using cognitive and depressive symptoms screening instruments. After two years, functional disability (instrumental activities of daily living), falls, hospitalisation, and polypharmacy were evaluated. Multinomial regression models were performed to assess the effects of cognitive impairment and depressive symptoms on outcomes. Results: 38.5% of the participants had a cognitive impairment, and 55.0% had depressive symptoms. Cognitive impairment at baseline was associated with an increased risk of disability to shopping (OR=2.946), performing housework (OR=2.196), and managing finances (OR=3.488). Depressive symptoms were related to a higher risk of dependence on traveling (OR=1.614), administering medications (OR=5.745), managing finances (OR=2.876), falls (OR=1.960), and polypharmacy (OR=2.464). Participants with the two associated conditions were at higher risk of dependence on using the telephone (OR=2.701), travelling (OR=2.177), shopping (OR=2.890), administering medications (OR=4.773), and managing finances (OR=3.799). Conclusion: Cognitive impairment was associated with dependence in three activities after two years. Depressive symptoms were related to a greater risk of dependence in three activities, falls, and polypharmacy. The cumulative effect of cognitive impairment and depressive symptoms negatively influenced the performance in five instrumental activities of daily living.

Factors associated with neurocognitive disorders in people living with HIV aged ≥ 50 years old in Brazil: a cross-sectional study
Introduction: There is a high prevalence of HIV-associated neurocognitive disorders (HAND), especially in people living with HIV (PLWH) who are ≥50 years old. Objective: The objective of this study was to identify the factors associated with HAND in PLWH who are ≥50 years old. Methods: This is a cross-sectional study involving 48 patients (Mean=59.6 years). We collected sociodemographic, clinical, and anthropometric data, and the instrumental activities of daily living (IADL) and International HIV Dementia Scale (IHDS) were administered for neurocognitive evaluation. Results: A total of 75% of individuals had HANDs, including 88.89% with asymptomatic disorders and 11.11% with mild/moderate disorders. IHDS scores were positively correlated with educational level, nutritional status, and viral load (VL) at the time of diagnosis, while negatively correlated with the number of diseases, number of medications, and blood glucose levels. Conclusion: To the best of our knowledge, this is one of few studies conducted exclusively with elderly PLWH that investigated the factors associated with HAND in an inland city from a developing country, showing that the main predictors of HANDs were education, VL at diagnosis, and blood glucose. Hence, results could support future studies and interventions among PLWH elsewhere, where resources are limited and HIV assistance may be more precarious and difficult.

Effects of Bacillus Calmette-Guérin (BCG Moscow) vaccination on white blood cell count: results of a randomized clinical trial
Introduction: Bacillus Calmette-Guérin (BCG) vaccination induces innate and specific responses that protect against some severe forms of tuberculosis and have nonspecific effects against other infections. Objective: To evaluate whether revaccination with BCG Moscow is associated with serum increase in total and differential leukocytes. Methods: We conducted an analytical study on the white blood cell count of 156 participants (BCG revaccination group: 80; Control group: 76) of a randomized clinical trial investigating BCG revaccination for the prevention or reduction of complications associated with COVID-19. Blood samples were collected before randomization and after 15 days of intervention. Values were expressed as mean (μ) and standard deviation, using paired t-tests and Student's t-test. Results: BCG revaccination did not alter leukocyte levels between revaccinated (μ, 6019.74±1865.33) and non-revaccinated groups (μ, 6278.75±1823.87), p=0.94. Stratification by sex, obesity, and age did not significantly affect white blood cell levels. Conclusion: Revaccination with BCG Moscow did not stimulate leukocyte production.

Analysis of ChatGPT responses to breastfeeding questions
Introduction: Artificial intelligence tools are impacting medicine in a way that makes knowledge more accessible to both doctors and patients, but their absolute accuracy is still little studied. Objective: This study aims to evaluate the quality of responses provided by ChatGPT to potential inquiries from families regarding breastfeeding. Methods: A cross-sectional study was conducted through an online questionnaire with active Brazilian pediatricians (n=56) who expressed their opinions on ten pairs of questions and answers related to breastfeeding. Questions were formulated based on common doubts, and responses were obtained after submitting the queries to ChatGPT. The quality of responses was assessed on a scale of 1 to 5 points. Results: The findings revealed an average score exceeding 4.0 for all questions posed to the artificial intelligence regarding "Clarity of the provided answer" and "Conformity with current scientific knowledge." Regarding "I am satisfied with the presented response," participants rated ChatGPT responses above 4.0 for most questions. Most pediatricians agreed with the statement, "If I were responding to this question for a real patient, my answer would be different." Conclusion: Responses generated by ChatGPT received high satisfaction rates from the population of pediatricians who evaluated them, being considered clear and based on updated scientific knowledge. However, most pediatricians stated they would provide different responses to their patients.

High-fat diet and fructose drink stimulate apoptotic signaling via cleaved caspase-3 protein in hepatic cells of rats
Introduction: The intake of a high-fat, high-fructose diet during childhood may lead to obesity, hepatic steatosis, and inflammation in adulthood. Objective: To investigate the effects on hepatic metabolism of intake of diets with various levels of fat associated with fructose drinks during childhood. Methods: Male 21-days-old rats were divided into groups: Control (C, 16.3% kcal from lipids diet and water); High-fat (HF, 45% kcal from lipids diet and fructose drink); and very high-fat (VHF, 60% kcal from lipids diet and fructose drink). After 10 weeks, blood and liver were collected for biochemical, histological, lipid profile, and Western blotting analyses. Results: The HF and VHF animals presented higher adiposity index, hepatic accumulation of lipids, and inflammatory cells, suggesting the treatments were effective at inducing non-alcoholic fatty liver disease in its inflammatory form. The hepatic content of cleaved caspase-3 and deposition of collagen fibers were increased in the HF group. Conclusion: In summary, lipid-rich diets combined with fructose drinks seem to promote the increase in body lipids content and accumulation of lipids, inflammation, activation of apoptotic signaling pathways, and the initiation of a fibrotic process in the liver in adulthood.

Epidemiological profile of self-medication by university students during the COVID-19 pandemic in Brazil
Introduction: Self-medication is characterized by drug consumption without a medical prescription to alleviate undesirable symptoms. During the COVID-19 pandemic, this practice may have been stimulated by the implementation of remote teaching with an extensive workload, the development of mental health disorders, and the dissemination of false information on social media. Objective: To outline the epidemiological profile of self-medication and drugs consumed by university students during the COVID-19 pandemic in Brazil. Methods: This is an analytical cross-sectional epidemiological study, in which data were collected through an online questionnaire sent by email to the coordinators of university courses in different regions of Brazil in January 2022. The prevalence of self-medication was calculated, and binomial logistic regression analysis and chi-square tests were applied to determine the influence of some variables on the practice of self-medication. Results: A prevalence of 48.43% of self-medication was detected among the 384 participants, the majority of whom were female and studied non-health-related areas. Associations (p<0.005) were observed between self-medication and the female sex, the Applied Social Sciences course, and having comorbidities. Furthermore, prevalences of 43.22%, 24.22%, and 16.15%, respectively, of consumption of analgesics, antihistamines and antidepressants were detected. Conclusion: In the pandemic context, a set of interconnected factors, such as gender, course, comorbidities, mental suffering, and low-severity symptoms can influence the practice of self-medication by university students.

Predictive factors for sexual dissatisfaction in men after traumatic spinal cord injury
Introduction: In addition to motor and sensory losses, the urinary tract and sexual function are also affected by spinal cord injury, with sexual dysfunction being one of the most common problems in these patients and its severity depends on the level and complexity of the injury. This alteration of sexual function occurs due to changes in the neurophysiological process, but this mechanism and its association with sexual satisfaction are not well established. Objective: To analyze the association between clinical and psychosocial factors and sexual satisfaction in men after traumatic spinal cord injury, as well as predictive factors for sexual dissatisfaction after the injury. Method: Observational study performed with 45 men, with traumatic and sexually active spinal cord injury. The International Erectile Function Index assessed sexual function, and the level and grade of the lesion were determined following the guidelines of the International Standards for Neurological Examination and Functional Classification of Spinal Cord Injury. Bi and multivariate analysis was applied to observe the association between factors, with a significance level of 0.05. Results: 45 individuals with mean lesion time in years 7.5 (CI 5.2 - 9.9) were evaluated. Frequency of monthly sexual intercourse is a risk factor (OR: 11.69, 95% CI: 2.16 - 63.19) for sexual dissatisfaction, as well as orgastic dysfunction (OR: 10,13; 95% CI: 1, 33-77, 18). Conclusion: Infrequent sexual relations and orgastic dysfunction are predictors of sexual dissatisfaction after spinal cord injury.

Knee pain in adults from the northeast of São Paulo, Brazil: prevalence, risk factors, and impact on quality of life
Introduction: The existing literature describes several risk factors associated with knee pain, including personal, psychological, and work-related factors, among others. Furthermore, several studies have shown the negative impact of knee pain on quality of life; however, there is a lack of knowledge about knee pain in Latin American populations. Objective: This study aims to investigate the prevalence, risk factors, and impact on the quality of life of knee pain in Brazilian adults. Methods: This cross-sectional study was based on a population survey with 600 individuals interviewed using questionnaires including a) sociodemographic and labor aspects; b) physical activity level (IPAC questionnaire); c) musculoskeletal symptoms (Nordic questionnaire); and d) quality of life (SF-36). Results: The prevalence of knee pain was 25.6% (95% confidence interval: 22.3–29.3%), and it was associated with being >60 years old, black ethnicity, mean or low income, overweight, depression, gastrointestinal and renal diseases, and persons who performed occupations requiring repetitive movements, sitting while using a computer, and standing. All individuals with knee pain demonstrated significantly greater risks for summaries of the physical components. Conclusion: Knee pain is associated with socioeconomic variables, work aspects, and lifestyle factors and impacts the quality of life.

Post-traumatic stress disorder in individuals who required hospitalization for COVID-19: A cross-sectional study
Introduction: Currently, the physical and functional consequences on individuals who have recovered from the severe form of the Covid-19 and are experiencing traumatic stress remain unknown. Objective: To assess post-traumatic stress disorder (PTSD) in individuals post-hospital discharge following COVID-19 and investigate its relationship with sociodemographic variables, quality of life, muscle strength and functional capacity. Methods: A cross-sectional study was conducted, including individuals of both genders aged between 31 and 79 years, who had recovered from COVID-19 and required hospitalization. Participants underwent evaluations for PTSD, physical activity level, mobility and balance (Timed Up and Go test – TUG), the distance covered in the 6-minute walk test (6MWT) and quality of life (Short Form-36 Health Srvey -SF-36). Results: Out of 153 eligible individuals, 60 successfully completed the assessments. The age range was 31 to 77 years, and 63.3% were female. PTSD was identified in 48.3%, with 38.7% exhibiting partial symptoms. Furthermore, 65.5% of individuals with PTSD were obese, and 62.1% were hypertensive. This group demonstrated a higher degree of sedentary behavior (p=0.009), increased frequency of intensive care unit hospitalization, and a greater number of days hospitalized, respectively (p<0.001 and p=0.010). They exhibited longer times in the TUG (p=0.014), shorter distances than predicted in the 6MWT (p=0.001), and a reduction in all domains of the SF-36. Conclusion: Given the findings of this study, the follow-up of these individuals needs to be continued in order to verify the permanence of these symptoms and functional manifestations.

Effects of low, moderate, and high-intensity aquatic exercise on joint edema in induced rat knee arthritis
Introduction: Arthritis has prompted interest in using physical exercise as therapy. This study assesses the effects of low-, moderate-, and high-intensity exercise on induced arthritis in male Wistar rats. Objective: To evaluate the impact of low-, moderate-, and high-intensity physical exercise on induced arthritis. Methods: Twenty 60-day-old rats were divided into 5 groups: Control Group Arthritis (GCA), Control Group Placebo (GCP), Group Low Physical Activity (GL), Group Moderate Physical Activity (GM), and Group Intense Physical Activity (GI). The physical activity groups received intra-articular injections of Zymosan in the right knee, followed by aquatic activity, swimming with a dorsal load for 30 minutes, 4 times weekly, for five weeks. Exercise intensity varied: GL 1%, GM 5%, GI 15% of body weight. At the end of the 5th week euthanasia was performed, and soleus muscles were histologically. Group comparisons: one-way ANOVA with Tukey or Kruskal-Wallis with Dunn's post-test, contingent on data homogeneity Levene test. Weight changes: Student’s T-test or ANOVA for repeated measurements, with Bonferroni's post-test for inter-week and first and last-week comparisons within each group. Results: There were no significant differences in inflammatory edema before or after exercise in joint diameter analysis. GI exhibited decreased inflammatory edema in the 3rd week post-activity. GM showed a substantial decrease in the 4th week compared to GL and GI. Post-intervention inflammation did not differ significantly among groups. Conclusion: Varying exercise intensities did not harm any group-induced arthritis in rats.

Regular exercise in adolescents with ACE gene polymorphism helps preventing cardiovascular risk factors
Introduction: Polymorphisms can influence the expression and production of regulatory components in the endocrine system. These include the renin-angiotensin-aldosterone system (RAAS), which plays, along with other environmental factors, a fundamental role in the pathogenesis of essential arterial hypertension in both adults and adolescents. Objective: To analyze the influence of the level of physical activity and the polymorphism in the ACE gene on cardiac autonomic modulation and the chance of cardiovascular risk in adolescents. Methods: 136 adolescents were divided into active (AG) and sedentary (SG) groups. The genotypic frequencies in SG group are DD (38), DI (12) and II (10); and AG group are DD (38), DI (15) and II (23). Blood pressure, body composition, physical activity level, and sexual maturation were assessed to characterize the groups. Afterward, an electrocardiogram was performed to analyze heart rate variability and oral mucosal cells were collected for the genotypic of angiotensin-converting enzyme. Results: The AG presented lower systolic blood pressure and sympathetic modulation when compared to the SG DD. Additionally, the odds ratio for the cardiovascular events was increased in the SG DD compared with that in AG with DD allele (AG DD) adolescents, as verified for the autonomic variables LF%, HF%, LF/HF, and SBP. Conclusion: Regular physical activity in adolescents can contribute to the maintenance of blood pressure levels, preventing autonomic imbalance and cardiovascular risk factors in adolescents with ACE gene polymorphism.

Temporal trend, spatial distribution and factors associated with detection and mortality from viral hepatitis B and C in Brazil (2010–2019)
Introduction: The elimination of viral hepatitis stands out as one of the goals on the agenda for 2030, particularly due to its significant impact on public health. Objective: To analyze the temporal trends, spatial distribution, and factors associated with the detection and mortality of viral hepatitis B and C in Brazil from 2010 to 2019. Methods: An ecological study focusing on Brazilian regions and federative units. Annual detection and mortality rates were calculated, trend analysis was conducted using polynomial regression models, thematic maps were developed for spatial distribution, and the Spearman correlation coefficient was used to assess the association with seven socioeconomic indicators. Results: Brazil exhibited a decreasing trend in detection and mortality rates for hepatitis. The Southern and Northern regions showed the highest rates of hepatitis B, with decreasing and stable trends, respectively. The highest rates of hepatitis C were observed in the Southern and Southeast regions, both showing a declining trend. Hepatitis B detection was highest in Acre and Rondônia, while hepatitis C detection was highest in Rio Grande do Sul and Acre. An increase in hepatitis C detection and a decline in mortality were observed in Pará and Acre. Hepatitis detection was inversely related to the illiteracy rate and directly associated with the human development index, life expectancy, and per capita income. Conclusion: Regional and state disparities were evident regarding the behavior of viral hepatitis B and C in Brazil, with locations having better development indices exhibiting higher detection rates.

Objective: To investigate the factors associated with the early readmission of hospitalized patients due to acute decompensation of cirrhosis. Methods: Data from the first hospitalization of each patient was considered during the study period and were followed up to the 90th day by telephone contact. A prospective cohort study in Southern Brazil. Results: Between 2011 and 2016, 280 patients were included in the study. The mean age was 55.68±11.21 years, and 71.8% were males with a mean MELD of 15.65±5.64 and 41.4% Child-Pugh C. Early readmission occurred in 91 cases (32.5%). In the logistic regression analysis, CLIF-SOFA variables (odds ratio [OR] 1.137, 95% confidence interval [CI] 1.003–1.289, p=0.045) and several complications present in the initial hospitalization (OR 1.503, 95% CI 1.074–2.105, p=0.018) independent of early readmission. Early readmission rates were 16.8% in patients with CLIF-SOFA <8 and less than 2 complications at admission and 49.2% in those with CLIF-SOFA ≥8 and 2 or more complications at the initial hospitalization. Conclusion: Simple parameters such as CLIF-SOFA and the number of complications of cirrhosis present at hospital admission are predictors of early readmission and can be used as tools to individualize the follow-up of cirrhotic patients after hospital discharge.

Parasitic contamination of lettuce: comparison between establishments located in areas with high and low economic values
Introduction: Diseases caused by contaminated food are a threat to public health. Lettuce (Lactuca sativa) is a widespread vegetable for human alimentation. Some systematic reviews showed parasitic contamination of lettuce in Brazil. Objective: To evaluate if the economic value of the places where lettuce is bought could be a determinant of parasitic contamination. Methods: We assessed the presence of parasites in the curly lettuces sold in the city of Passo Fundo, Brazil, and compared the frequency of contamination between markets and fruit stores, and between areas with high and low economic values. 130 samples of lettuce from 65 commercial establishments scattered throughout the city were washed with distilled water and analyzed under optical microscopy after 24 hours of spontaneous sedimentation method. Results: Parasitic forms were found in 80% of the samples, namely: ciliated cysts (probable Balantioides coli), larvae of nematode, Ascaris lumbricoides, cestode eggs, Giardia lamblia, Hymenolepis nana, Entamoeba coli, and Fasciola hepatica. Contamination by larvae of nematode was more frequent in fruit stores than in markets (35.9% vs. 19.7%; p=0.039). Areas with high and low economic values had the same frequency of contamination, but there was a trend to higher contamination by cestode eggs in areas with low economic values. Conclusion: This study was the first to show that the frequency of parasitic contamination is not different compared to establishments located in areas of high and low economic values, refuting any common sense that regions of the city with higher income are less exposed to parasitic contamination of food.

Effects of gestational and lactational exposure to ethanol on body and bone growth of rat offspring
Introduction: Ethanol is the most widely consumed drug in the world. When this consumption occurs by pregnant women, the harmful effects extend to the fetus. There are few data available on its effects on infants. Objective: To evaluate the effects of maternal ethanol consumption during pregnancy (prenatal) as well as during pregnancy and lactation (pre- and post-natal). Methods: 12 Wistar rats were divided into ethanol and control groups. Ethanol group received ethanol (4 g/kg/day) via oral gavage from the ninth day of gestation to the 17th day of lactation. The weight and length of the pups were determined at birth and 17 days of age. The length and width of the femur and tibia and the thickness of the epiphysis were measured in the neonates, and the thickness of the articular cartilage, epiphyseal plate, and its zones were measured at 17 days of age. CDC-47 immunoexpression was evaluated and the expressions of aggrecan, collagen type II, and collagen type X were determined by RT-PCR. Results: In neonates, rats in the group with prenatal exposure to ethanol were significantly shorter (body length) than the control group. At 17 days of age, the femur of the group with pre-and postnatal exposure to ethanol showed a significantly lower percentage of proliferating chondrocytes, as evidenced by the different CDC-47 immunoexpression between groups. Conclusion: Prenatal exposure to ethanol in rats reduced body length at birth while pre- and postnatal exposure to ethanol decreased the proliferation of femoral epiphyseal plate chondrocytes.

Physical exercise in the prevention and rehabilitation of Osteopenia in premature infants and children with Down Syndrome: a systematic review
Introduction: Osteopenia is a systemic metabolic disease derived from decreased bone formation and/or increased resorption without compromising microarchitecture, causing increased fragility and susceptibility to fractures, which can affect growth in childhood and adolescence. Objective: Identify which interventions through physical exercise can help in the treatment and prevention of osteopenia/osteoporosis in premature infants and children with Down Syndrome. Methods: The searches were conducted in specific databases in Health Sciences, structured in the form PICOS, including randomized clinical trials related to physical exercise against osteopenia in premature children and with Down Syndrome from 0 to 12, using the Health Sciences Descriptors to identify the keywords. Studies with high methodological quality were eligible for meta-analysis in the random effects model. Results: Of the 15 articles analyzed, it was observed that both infants, children, and adolescents in the experimental groups, who performed physical exercise, showed statistically significant differences in at least one of the biomarkers of bone formation or bone resorption and, in the same way, showed statistical differences in densitometry and ultrasound measurements. The meta-analysis performed with the studies in preterm infants showed statistically significant mean differences of 0.77 and 0.61 for bone formation in the intervention group and 1.07 for the intensity of 10 repetitions in the Moyer and Mileur protocol. Conclusion: Physical exercise contributes to greater bone formation and reduction of bone resorption, effectively treating and preventing metabolic diseases of osteo in premature infants and children with Down Syndrome.
