Zika virus prevention behaviors and knowledge among male partners of pregnant people and lack of condom use as a prevention behavior from the Zika en Embarazadas y Niños (ZEN) prospective cohort study, Colombia.

OBJECTIVE: Zika virus (ZIKV) infection in pregnancy can cause brain and eye abnormalities and neurodevelopmental sequelae. In the absence of medical countermeasures, behavioral interventions were recommended to prevent mosquito bites and sexual transmission of ZIKV. This report uses data from the Zika en Embarazadas y Niños (ZEN) prospective cohort study in Colombia to describe the knowledge, attitudes, and behaviors (KAB) related to ZIKV prevention in male partners compared to those of their pregnant partners at study enrollment during February 2017-2018. RESULTS: Most male partners reported wearing protective clothing such as long pants (97.6%) and long sleeves (72.8%), as well as covering ankles and feet (89.1%) to prevent ZIKV infection. When comparing the preventive behavior of condom use between male and pregnant partners, 26 pairs (10.0%) both responded that they performed the behavior. Overall, 25.1% of male partners and 18.9% of pregnant people reported any condom use during the three months before enrolling in ZEN. When comparing other preventive behaviors between male and pregnant partners, the behavior which was most frequently reported by both partners was wearing long pants (85.4%), and the least frequently reported by both partners was using condoms after finding out about a partner's pregnancy (3.4%).

Selenium Compounds Affect Differently the Cytoplasmic Thiol/Disulfide State in Dermic Fibroblasts and Improve Cell Migration by Interacting with the Extracellular Matrix.

Deficient wound healing is frequently observed in patients diagnosed with diabetes, a clinical complication that compromises mobility and leads to limb amputation, decreasing patient autonomy and family lifestyle. Fibroblasts are crucial for secreting the extracellular matrix (ECM) to pave the wound site for endothelial and keratinocyte regeneration. The biosynthetic pathways involved in collagen production and crosslinking are intimately related to fibroblast redox homeostasis. In this study, two sets of human dermic fibroblasts were cultured in normal (5 mM) and high (25 mM)-glucose conditions in the presence of 1 µM selenium, as sodium selenite (inorganic) and the two selenium amino acids (organic), Se-cysteine and Se-methionine, for ten days. We investigated the ultrastructural changes in the secreted ECM induced by these conditions using scanning electron microscopy (SEM). In addition, we evaluated the redox impact of these three compounds by measuring the basal state and real-time responses of the thiol-based HyPer biosensor expressed in the cytoplasm of these fibroblasts. Our results indicate that selenium compound supplementation pushed the redox equilibrium towards a more oxidative tone in both sets of fibroblasts, and this effect was independent of the type of selenium. The kinetic analysis of biosensor responses allowed us to identify Se-cysteine as the only compound that simultaneously improved the sensitivity to oxidative stimuli and augmented the disulfide bond reduction rate in high-glucose-cultured fibroblasts. The redox response profiles showed no clear association with the ultrastructural changes observed in matrix fibers secreted by selenium-treated fibroblasts. However, we found that selenium supplementation improved the ECM secreted by high-glucose-cultured fibroblasts according to endothelial migration assessed with a wound healing assay. Direct application of sodium selenite and Se-cysteine on purified collagen fibers subjected to glycation also improved cellular migration, suggesting that these selenium compounds avoid the undesired effect of glycation.

Metabolic Biomarkers in Adults with Type 2 Diabetes: The Role of PPAR-γ2 and PPAR-ß/δ Polymorphisms.

Glucose and lipid metabolism regulation by the peroxisome proliferator-activated receptors (PPARs) has been extensively reported. However, the role of their polymorphisms remains unclear. OBJECTIVE: To determine the relation between PPAR-γ2 rs1801282 (Pro12Ala) and PPAR-ß/δ rs2016520 (+294T/C) polymorphisms and metabolic biomarkers in adults with type 2 diabetes (T2D). MATERIALS AND METHODS: We included 314 patients with T2D. Information on anthropometric, fasting plasma glucose (FPG), HbA1c and lipid profile measurements was taken from clinical records. Genomic DNA was obtained from peripheral blood. End-point PCR was used for PPAR-γ2 rs1801282, while for PPAR-ß/δ rs2016520 the PCR product was digested with Bsl-I enzyme. Data were compared with parametric or non-parametric tests. Multivariate models were used to adjust for covariates and interaction effects. RESULTS: minor allele frequency was 12.42% for PPAR-γ2 rs1801282-G and 13.85% for PPAR-ß/δ rs2016520-C. Both polymorphisms were related to waist circumference; they showed independent effects on HbA1c, while they interacted for FPG; carriers of both PPAR minor alleles had the highest values. Interactions between FPG and polymorphisms were identified in their relation to triglyceride level. CONCLUSIONS: PPAR-γ2 rs1801282 and PPAR-ß/δ rs2016520 polymorphisms are associated with anthropometric, glucose, and lipid metabolism biomarkers in T2D patients. Further research is required on the molecular mechanisms involved.

Discovery of Novel miRNAs in Colorectal Cancer: Potential Biological Roles and Clinical Utility.

Deregulated miRNAs are associated with colorectal cancer (CRC), with alterations depending on the tumor location. Novel tissue-specific miRNAs have been identified in different tumors and are associated with cancer. We used miRMaster to identify novel miRNAs in CRC from the TCGA and GEO data (discovery and validation groups). We used TCGA data from five tissues to analyze miRNA tissue specificity. miRDB was used to predict miRNA targets, and the UCSC Xena Browser was used to evaluate target expression. After successive analyses, we identified 15 novel miRNAs with the same expression patterns in CRC in both the discovery and validation groups. Four molecules (nov-miR-13844-5p, nov-miR-7154-5p, nov-miR-5035-3p, and nov-miR-590-5p) were differentially expressed in proximal and distal CRC. The nov-miR-3345-5p and nov-miR-13172-3p, which are upregulated in tumors, are only expressed in colorectal tissues. These molecules have been linked to a worse prognosis in right-sided colon and rectal carcinomas. An analysis revealed an association between eight novel miRNAs and 81 targets, mostly cancer-related genes, with varying expression based on tumor location. These findings provide new miRNAs with potential biological relevance, molecular biomarkers, and therapeutic targets for CRC treatment.

Sociodemographic Barriers to Physical Activity and Healthy Diet Through Social Networks in Mexican Breast Cancer Survivors.

Introduction Female breast cancer (BC) survivors are affected by poor eating habits and physical inactivity due to certain environmental, physical, and social barriers to healthy lifestyles. This study aimed to identify the sociodemographic, physical, and economic barriers hindering the adoption of physical activity (PA) and a healthy diet, as well as providing insights into how BC survivors cope with these barriers using social networks. Methods A cross-sectional mixed-methods study was conducted, with a self-administered questionnaire and open-ended questions to determine the barriers to PA and healthy eating, while in the second phase, an interpretive qualitative study was carried out with semi-structured interviews. Descriptive statistics, odds ratios (ORs), correspondence analysis, and multivariate analysis were used to estimate the association between moderate to vigorous PA and fruit and vegetable consumption and BC covariates. Results During the COVID-19 lockdown, 150 Mexican BC survivors were studied. The multivariate analysis showed that age (OR = 2.7, 95% CI: 1.0 to 7.03), socioeconomic level (OR = 3.2, 95% CI: 1.3 to 8.2), and overweight (OR = 3.6, 95% CI: 1.5 to 9.7) were significantly associated with low schooling. BC diagnosis of less than three years and age > 40 years were associated with lack of exercise. Survivors individually addressed the challenges associated with BC without the support of specialists. As a result, they sought information on social networks. Conclusions Regarding BC survivors, age > 40 years, low socioeconomic status, and being overweight were important gaps to PA and a healthy diet. In the testimonials, the primary obstacle to engaging in PA was lack of time, while the high cost of food was the most frequently cited reason for not following a healthy diet. Many of the individuals maintained a poor diet with a low intake of fruits and vegetables. Thus, appropriate information must be provided using technologies to develop skills to deal with BC.

Evaluation the Potential of Onion/Laponite Composites Films for Sustainable Food Packaging with Enhanced UV Protection and Antioxidant Capacity.

Agro-industrial residues have attracted attention for their applications in the field of biodegradable packaging. Recently, our research group has developed onion-based films with promising properties for this type of application due to their non-toxicity, biocompatibility and biodegradability. Therefore, in this study, we investigated the effect of Laponite clay concentration on the physicochemical and antioxidant properties of the onion-based films, which were prepared by a casting method. The XRD and FTIR data confirm the presence of the mineral clay in the onion-based films. These findings are consistent with those obtained from FE-SEM analysis, which revealed the presence of typical Laponite grains. In terms of wettability, the results show that the clay decreases the hydrophilic character of the material but slightly increases the water vapor permeation. Optical characterization revealed that the materials exhibited zero transmittance in the UV region and increased opacity in the visible region for composites containing 5% and 10% Laponite. Furthermore, the antioxidant test demonstrated higher antioxidant potential in the composites compared to the pure films. Consequently, these results suggest that the formation of Laponite and onion composites could be an essential strategy for developing natural polymers in the field of food contact packaging.

Programa de salud y enfoque sociocultural en comunidades rurales de Ancash, Perú / Health Program and Sociocultural Approach in Rural Communities of Ancash, Peru

Introducción: En intervenciones con tecnologías apropiadas, orientadas a mejorar la salud respiratoria, predomina el precepto de que en comunidades rurales, su sola aplicación resuelve los problemas de salud. Aun cuando la educación socio-cultural ha adquirido una alta prioridad, sigue ocupando una importancia menor. Objetivo: Comprender cómo las particularidades y las semejanzas de los programas de salud con tecnología apropiada, de ayer y de hoy, impactan en la calidad de vida de las mujeres rurales. Métodos: Se realizó un estudio con diseño cualitativo. En un primer momento, en tres grupos de La Esperanza, se evaluaron tres propuestas: Grupo 1 (Cocina Mejorada-Programa Educativo), Grupo 2 (Cocina Mejorada) y Grupo 3 (Programa Educativo). Cada grupo estuvo conformado por 15 mujeres. La información se obtuvo a partir de los cambios observados y las notas de campo. En un segundo momento, se analizaron las percepciones sobre cocinas mejoradas recientemente implementadas, a través de la realización de entrevistas a tres mujeres residentes en Chamana. Resultados: En La Esperanza, el grupo 1 alcanzó cambios ostensibles en todas las variables. El grupo 2 mantuvo prácticas inadecuadas. El grupo 3 logró cambios en las variables no vinculadas con la tecnología apropiada. En Chamana, debido a una capacitación insuficiente, las mujeres no reconocen las buenas prácticas para el uso de las cocinas mejoradas ni su impacto en la salud. Conclusiones: Una implementación con cocina mejorada acompañada con un pertinente programa educativo resulta cualitativamente superior. La presunción de que las tecnologías apropiadas por sí solas, podrían generar los cambios deseados, es cuestionable a todas luces(AU)

Introduction: In interventions with appropriate technologies, aimed at improving respiratory health, the precept that in rural communities their application alone solves health problems predominates. Although socio-cultural education has acquired a high priority, it is still of lesser importance. Objective: To understand how the particularities and similarities of health programs with past and present appropriate technology impact the quality of life of rural women. Methods: A qualitative study was conducted. Initially, three proposals were evaluated in three groups of La Esperanza: Group 1 (Improved Cooking-Educational Program), Group 2 (Improved Cooking) and Group 3 (Educational Program). Each group consisted of 15 women. Information was obtained from observed changes and field notes. In a second moment, perceptions about recently implemented improved cookstoves were analyzed, through interviews with three women living in Chamana. Results: In La Esperanza, group 1 achieved significant changes in all variables. Group 2 maintained inadequate practices. Group 3 achieved changes in variables not linked to appropriate technology. In Chamana, due to insufficient training, women do not recognize good practices for the use of improved cookstoves and their impact on health. Conclusions: An implementation with improved cooking accompanied by a relevant educational program is qualitatively superior. The presumption that appropriate technologies alone could bring about the desired changes is clearly questionable(AU)

Can mixed circuit training elicit the recommended exercise intensity and energy expenditure in people after stroke?

PURPOSE: To investigate whether mixed circuit training (MCT) elicits the recommended exercise intensity and energy expenditure in people after stroke, and to establish the between-day reproducibility for the percentages of heart rate reserve (%HRR), oxygen uptake reserve (%VO2R), and energy expenditure elicited during two bouts of MCT. METHODS: Seven people aged 58 (12) yr, who previously had a stroke, performed a cardiopulmonary exercise test, a non-exercise control session, and two bouts of MCT. The MCT included 3 circuits of 10 resistance exercises at 15-repetition maximum intensity, with each set of resistance exercise interspersed with 45-s of walking. Expired gases were collected during the MCT and control session and for 40 min afterward. Control session was necessary to calculate the net energy expenditure associated with each bout of MCT. RESULTS: Mean %VO2R (1st MCT: 51.1%, P = .037; 2nd MCT: 54.0%, P = .009) and %HRR (1st MCT: 66.4%, P = .007; 2nd MCT: 67.9%, P = .010) exceeded the recommended minimum intensity of 40%. Both %VO2R (P = .586 and 0.987, respectively) and %HRR (P = .681 and 0.237, respectively) during the 1st and 2nd bouts of MCT were not significantly different to their corresponding gas exchange threshold values derived from cardiopulmonary exercise testing. Mean net total energy expenditure significantly exceeded the minimum recommend energy expenditure in the 1st (P = .048) and 2nd (P = .023) bouts of MCT. Between-day reproducibility for %HRR, %VO2R, and energy expenditure was excellent (ICC: 0.92-0.97). CONCLUSIONS: MCT elicited physiological strain recommended for improving health-related fitness in people after stroke and these responses demonstrated excellent between-day reproducibility.

Advances in the Molecular Landscape of Lung Cancer Brain Metastasis.

Lung cancer is one of the most frequent tumors that metastasize to the brain. Brain metastasis (BM) is common in advanced cases, being the major cause of patient morbidity and mortality. BMs are thought to arise via the seeding of circulating tumor cells into the brain microvasculature. In brain tissue, the interaction with immune cells promotes a microenvironment favorable to the growth of cancer cells. Despite multimodal treatments and advances in systemic therapies, lung cancer patients still have poor prognoses. Therefore, there is an urgent need to identify the molecular drivers of BM and clinically applicable biomarkers in order to improve disease outcomes and patient survival. The goal of this review is to summarize the current state of knowledge on the mechanisms of the metastatic spread of lung cancer to the brain and how the metastatic spread is influenced by the brain microenvironment, and to elucidate the molecular determinants of brain metastasis regarding the role of genomic and transcriptomic changes, including coding and non-coding RNAs. We also present an overview of the current therapeutics and novel treatment strategies for patients diagnosed with BM from NSCLC.

Mixed circuit training acutely reduces arterial stiffness in patients with chronic stroke: a crossover randomized controlled trial.

PURPOSE: Investigate whether a single bout of mixed circuit training (MCT) can elicit changes in arterial stiffness in patients with chronic stroke. Second, to assess the between-day reproducibility of post-MCT arterial stiffness measurements. METHODS: Seven participants (58 ± 12 years) performed a non-exercise control session (CTL) and two bouts of MCT on separate days in a randomized counterbalanced order. The MCT involved 3 sets of 15 repetition maximum for 10 exercises, with each set separated by 45-s of walking. Brachial-radial pulse wave velocity (br-PWV), radial artery compliance (AC) and reflection index (RI1,2) were assessed 10 min before and 60 min after CTL and MCT. Ambulatory arterial stiffness index (AASI) was calculated from 24-h recovery ambulatory blood pressure monitoring. RESULTS: Compared to CTL, after 60 min of recovery from the 1st and 2nd bouts of MCT, lower values were observed for br-PWV (mean diff = - 3.9 and - 3.7 m/s, respectively, P < 0.01; ICC2,1 = 0.75) and RI1,2 (mean diff = - 16.1 and - 16.0%, respectively, P < 0.05; ICC2,1 = 0.83) concomitant with higher AC (mean diff = 1.2 and 1.0 × 10-6 cm5/dyna, respectively, P < 0.01; ICC2,1 = 0.40). The 24-h AASI was reduced after bouts of MCT vs. CTL (1st and 2nd bouts of MCT vs. CTL: mean diff = - 0.32 and - 0.29 units, respectively, P < 0.001; ICC2,1 = 0.64). CONCLUSION: A single bout of MCT reduces arterial stiffness during laboratory (60 min) and ambulatory (24 h) recovery phases in patients with chronic stroke with moderate-to-high reproducibility.

Appetite and energy intake following a bout of circuit resistance training in chronic hemiparetic stroke patients: a preliminary randomized controlled trial.

PURPOSE: The main aim of this study was to investigate the effects of circuit resistance training (CRT) on post-exercise appetite and energy intake in chronic hemiparetic stroke patients. A secondary aim was to evaluate the reproducibility of these effects. METHODS: Seven participants met the eligibility criteria and, in a randomized order, participated in a non-exercise control session (CTL) and two bouts of CRT. The CRT involved 10 exercises with 3 sets of 15-repetition maximum per exercise, performed using a vertical loading approach, with each set interspersed with 45s of walking. Expired gases were carried out   to calculate the net energy cost of the exercise and the relative energy intake post-CTL/CRT. Hunger, fullness, desire to eat, and energy intake were assessed at baseline and for 12 h after CTL and CRT. RESULTS: Compared to CTL, hunger, desire to eat (P < .001), and relative energy intake (P < .05) were significantly lower after CRT, whereas the perception of fullness was significantly higher (P < .001). Significant differences between CTL and CRT were observed only for the first 9 h of the post-exercise period for hunger, fullness, and desire to eat (P < .05). No significant differences in appetite or relative energy intake were observed between the two bouts of CRT. CONCLUSIONS: A bout of CRT elicited decreased post-exercise appetite and relative energy intake in chronic hemiparetic stroke patients. Decreased appetite perceptions lasted for around 9 h and were reproducible.

Hemispheric lateralization, endothelial function, and arterial compliance in chronic post-stroke individuals: A cross-sectional exploratory study.

Purpose/Aim: Cardiovascular function is controlled and regulated by a functional brain-heart axis. Although the exact mechanism is not fully understood, several studies suggest a hemispheric asymmetry in the neural control of cardiovascular function. Thus, the purpose of this study was to examine whether endothelial function and arterial compliance differ between individuals with left- and right-sided strokes.Materials and Methods: This was a cross-sectional exploratory study. Thirty individuals more than 6 months after stroke participated in the study. The endothelial function was assessed by ultrasound-measured flow-mediated dilation of the nonparetic arm brachial artery (baFMD). The arterial stiffness was assessed by measuring carotid-femoral pulse wave velocity (cfPWV) and central aortic pulse wave analysis [augmentation index (AIx), augmentation index normalized to a heart rate of 75 bpm (AIx@75) and reflection magnitude (RM)] using applanation tonometry. Results: Participants with right-sided stroke had worse endothelial function than those with left-sided stroke. This difference (baFMD = 2.51%) was significant (p = 0.037), and it represented a medium effect size (r = 0.38). Likewise, they had higher arterial stiffness than those with left-sided stroke. This difference (AIx = 10%; RM = 7%) was significant (p = 0.011; p = 0.012), and it represented a medium effect size (r = 0.48; r = 0.47).Conclusions: Our findings suggest that individuals with right-sided stroke have reduced endothelial function and arterial compliance compared to those with left-sided stroke. These data may indicate that those with right-sided strokes are more susceptible to cardiovascular events.

Acute effects of mixed circuit training on hemodynamic and cardiac autonomic control in chronic hemiparetic stroke patients: A randomized controlled crossover trial.

Objectives: To investigate whether a single bout of mixed circuit training (MCT) can elicit acute blood pressure (BP) reduction in chronic hemiparetic stroke patients, a phenomenon also known as post-exercise hypotension (PEH). Methods: Seven participants (58 ± 12 years) performed a non-exercise control session (CTL) and a single bout of MCT on separate days and in a randomized counterbalanced order. The MCT included 10 exercises with 3 sets of 15-repetition maximum per exercise, with each set interspersed with 45 s of walking. Systolic (SBP) and diastolic (DBP) blood pressure, mean arterial pressure (MAP), cardiac output (Q), systemic vascular resistance (SVR), baroreflex sensitivity (BRS), and heart rate variability (HRV) were assessed 10 min before and 40 min after CTL and MCT. BP and HRV were also measured during an ambulatory 24-h recovery period. Results: Compared to CTL, SBP (∆-22%), DBP (∆-28%), SVR (∆-43%), BRS (∆-63%), and parasympathetic activity (HF; high-frequency component: ∆-63%) were reduced during 40 min post-MCT (p < 0.05), while Q (∆35%), sympathetic activity (LF; low-frequency component: ∆139%) and sympathovagal balance (LF:HF ratio: ∆145%) were higher (p < 0.001). In the first 10 h of ambulatory assessment, SBP (∆-7%), MAP (∆-6%), and HF (∆-26%) remained lowered, and LF (∆11%) and LF:HF ratio (∆13%) remained elevated post-MCT vs. CTL (p < 0.05). Conclusion: A single bout of MCT elicited prolonged PEH in chronic hemiparetic stroke patients. This occurred concurrently with increased sympathovagal balance and lowered SVR, suggesting vasodilation capacity is a major determinant of PEH in these patients. This clinical trial was registered in the Brazilian Clinical Trials Registry (RBR-5dn5zd), available at https://ensaiosclinicos.gov.br/rg/RBR-5dn5zd. Clinical Trial Registration: https://ensaiosclinicos.gov.br/rg/RBR-5dn5zd, identifier RBR-5dn5zd.

Support for Mothers, Fathers, or Guardians of Transgender Children and Adolescents: A Systematic Review on the Dynamics of Secondary Social Networks.

Mothers', fathers', or guardians' support for disclosures of diverse gender identity has significant relationships with decreased suicidality for transgender children and adolescents. They play an essential role in facing transphobia, protecting trans children, and strengthening the expression of their identity. These guardians need structural, emotional, and informative support; they need to be prepared to recognize and manage of their own feelings, as well as deal with the challenges that come with new social contexts of transphobia in schools, health institutions, and other community spaces. This study aimed to analyze the scientific evidence on the dynamics of secondary social networks to support mothers, fathers, or guardians of transgender children and adolescents. This is a systematic review of qualitative studies, guided by PRISMA guidelines. Controlled and free vocabularies were used to survey the primary studies in the following databases: EMBASE; Scopus; MEDLINE; Cumulative Index to Nursing and Allied Health Literature (CINAHL); PsycInfo; Latin American and Caribbean Literature in Health Sciences (LILACS); and Web of Science. A total of 28 articles made up the final sample of this review. Secondary social networks were described as fragile, characterized by conflicting and broken ties with healthcare services and professionals, isolation and unpreparedness from schools, and emotional and informational support from peer groups and some qualified healthcare professionals. The literature shows the potential of the dynamics of secondary social support networks; however, it presented the unpreparedness of professionals and institutional policies for welcoming transgender children and adolescents and their families, with the peer group being the main emotional and informative support network.

Apocrine gland adenocarcinoma in a persian cat remission with homeopathic treatment: case report

Apocrine gland carcinomas are rare malignant neoplasms that occur in cats. Available treatment is surgical, would lead to total ablation of the external acoustic meatus and usually recurrent [1,2].Methodology:In December 2020, a homeopathic consultation of the feline, male, Persian, 13 years old, a history of the disease was reported, which started in 2015, adding up to six recurrences of tumor processes in the eyelids and recent formation in the left ear canal.The result of the histopathological examination confirmed apocrine adenocarcinoma.Prior to homeopathic treatment, tumors recurred despite surgical interventions and prophylactic treatment with trichloracetic acid.However, remaining formations were noted in the eyelids and ear canal. It has a rounded blackened shape in the upper right eyelid measuring 0.4 cm and the lower 0.2 cm, round. In the left ear canal, around 1.6 cm, in addition to 4 points scattered in the ear folds. Homeopathic treatment was started for two months with Arsenicum album30 cH, twice a day; Carcinosinum 200 cH, once a day, and complex containing Avena sativa4 cH, Echinacea angustifolia4 cH, Conium maculatum6 cH, Thuja officinalis6 cH and Silicea terra6 cH, four times a day. Every two months, the clinical picturewas reassessed, potenciesand frequencies readjusted.In a few months,there was complete remission of the tumor, recovery of welfare, and improvement in mood and appetite. The free and informed consent term was signed. There was no recurrence of tumors until May2022. Conclusion:This study proved to be effective, documented with photos and exams. Approaching a rare case may provide a new therapeutic possibility. The credibility of quality homeopathic case reports has been increasing due to methodological requirements using tools developed in recent studies.

Phenotypic Changes in Mammary Adenocarcinoma (4T1) cells In Vitro after Treatment with Carcinosinum.

OBJECTIVE: The present study aimed to identify possible phenotypic changes in 4T1 (murine mammary adenocarcinoma) cells in vitro, including viability, HER-2 (human epidermal growth factor receptor-type 2) expression, and metastatic potential, after treatment with Carcinosinum in different homeopathic dilutions (12cH, 30cH, 200cH) shaken mechanically in pure, sterile, water from a commercial stock dilution. METHODS: Treated cells were cultured in R10 medium, using 24-well plates, 105 cells per well, and treated with vehicle, Carcinosinum 12cH, 30cH or 200cH; untreated cells were used as the baseline control. After 24 hours of treatment, the percentage of apoptotic cells was analyzed by annexin V. Cell morphology was evaluated by microscopy after hematoxylin-eosin and Giemsa staining, whilst HER-2 expression was assessed using immunocytochemistry. The metastatic potential was determined by the expression and activity of the enzyme matrix metalloproteinase 9 (MMP-9) using zymography. The cytokine profile was established using the cytometric bead array method. RESULT: Treatment of 4T1 cells in vitro with Carcinosinum 30cH produced an increase in the number of annexin V-positive cells (apoptosis) and decreased expression of proactivated MMP-9. Cells treated with Carcinosinum 200cH presented hyper-expression of HER-2 on the plasma membrane, identified by immunocytochemistry. There were no differences in cytokine production among treatments. CONCLUSION: The data show promising results for Carcinosinum 30cH in vitro, but in vivo studies are also required to evaluate the role of tumor microenvironment in its effects.

A Perspective of the COVID-19 Pandemic in the Plastic Waste Management and Cooperatives of Waste Pickers in Brazil.

Brazil is the fourth largest producer of plastic waste in the world. Among all the challenges the country had faced in the development of public policies for the banning of single-use plastics, the new coronavirus pandemic scenario determined the suspension of these laws indefinitely. In 2020, Brazil became the global epicenter of COVID-19. This scenario changed the habit and behavior of Brazilian consumers, who increased the consumption of plastics due to their importance in applications as protective material. The country also has social problems related to waste management that depend mainly on waste pickers. These workers need social visibility and protection not only to face the current health crisis but also to guarantee their income and survival. This work aims to discuss the increase in single-use plastics that are not intended for recycling and the respective environmental, economic, and social impacts for the country. We demonstrate the lack of data on waste management in Brazil and highlight the importance of the social inclusion of waste pickers for a circular economy. Especially after the change of scenario with the COVID-19 pandemic, the country must have adequate planning and improvements in waste management, recycling programs, and political intervention to raising awareness among the population and guaranteeing social rights for waste pickers.

Bibliometria dos trabalhos de conclusão do curso de Odontologia do Campus VII Ida Universidade Estadual da Paraíba: panorama de uma faculdade interiorana / Monograph bibliometrics of the dental course at Universidade Estadual da Paraíba Campus VIII: overview of a university in a small town

A realização do trabalho de conclusão de curso (TCC)na graduação, além de ser uma exigência, permite que oestudantetenha contato ativo com as metodologias de pesquisa, proporcionando assim o desenvolvimento de suacapacidade crítica e questionadora. No entanto, pouco se sabe sobre o perfil dos TCCs conduzidos nos cursos de Odontologia brasileiros. Desta forma, o presente estudo teve por objetivo identificar a tendência da produção científica e o perfil bibliométrico dos TCCs do curso de Odontologia da Universidade Estadual da Paraíba (UEPB)doCampus VIII.Foi realizado umestudo observacional descritivo, utilizando atécnica de documentação indireta, por meio de um levantamento de dados de documentos em arquivos públicos da UEPB. De um total de 150 TCCs cadastradosdo curso de Odontologia, a maioria foi defendida por mulheres, principalmente no ano de 2016.As áreas mais frequentes dos temas foram Patologia e Endodontia.O tipo de estudo mais prevalente foi a modalidade pesquisa, principalmente epidemiológica.Apenas 9,3% dos estudos forampublicados, principalmente em revistas de qualis B4e na língua portuguesa. Pode-se verificarque apesar da pesquisa ser bastante realizada pelos estudantes de Odontologia do Campus VIII, ela ainda não está sendo divulgada apropriadamente. Contudo, alguns poucos estudos foram publicados em periódicos de destaque (AU).

Besides being a requirement, writing a monograph to conclude an undergraduate course places students in active contact with research methods, enabling the development of critical, questioning capacity. However, little is known regarding the profile of monographs written for Brazilian dental courses. Therefore, the aim of the present study was to identify the trend in scientific production and the bibliometric profile of monographs for the dental course at Universidade Estadual da Paraíba (UEPB), Campus VIII. A descriptive, observational study was conducted using the indirect documentation method through a survey of documentaldata in public archives of UEPB. Among a total of 150 monographs registered with the dental course, most were presented by women, especially in the year 2016. The most frequent fields were pathology and endodontics. The most prevalent type of study was the research modality, especially epidemiological. Only 9.3% of the studies were published, mainly in "Qualis B4" journals and in Portuguese. Although students of dentistry conduct research, it is not being divulged appropriately. However, a few studies werepublished in high-impact journals (AU).

Life-long arsenic exposure damages the microstructure of the rat hippocampus.

Epidemiological studies demonstrate that arsenic exposure is associated with cognitive dysfunction. Experimental arsenic exposure models showed learning and memory deficits and molecular changes resembling the functional and pathologic neurodegeneration features. The present work focuses on hippocampal pathological changes in Wistar rats induced by continuous arsenic exposure from in utero up to 12 months of age, evaluated by magnetic resonance imaging along with immunohistochemistry. Diffusion-weighted images revealed age-related lower fractional anisotropy and higher radial-axial and mean diffusivity at 6 and 12 months, indicating that arsenic exposure leads to hippocampal demyelination. These structural alterations were paralleled by immunohistochemical changes that showed a significant loss of myelin basic protein in CA1 and CA3 regions accompanied by increased glial fibrillary acidic protein expression at all time-points studied. Concomitantly, arsenic exposure induced an altered morphology of astrocytes at all studied ages, whereas increased synaptogenesis was only observed at two months of age. These results suggest that environmental arsenic exposure is linked to impaired hippocampal connectivity and perhaps early glial senescence, which together might resemble a premature aging phenomenon leading to cognitive deficits.
