Change in Defense Mechanisms During a Brief Cognitive Behavioral Therapy for Obsessive-Compulsive Disorder.

ABSTRACT: Defense mechanisms (DMs) are strategies used by the individuals to protect the ego. Therefore, compulsive behaviors in obsessive-compulsive disorder (OCD) can be recognized as DMs. We analyzed how DMs changed in a brief cognitive behavioral therapy (CBT) for OCD. This was a quasi-experimental study with 92 OCD patients (aged 18-60 years). We used the Mini International Neuropsychiatric Interview to confirm OCD diagnosis, and we assessed the DMs with the Defense Style Questionnaire at three time points. Through a latent change score modeling, we found that the mature mechanism presented a constant change during the therapy. This mechanism increased in average 0.37 points at each measured moment of CBT, showing a linear trajectory. Neurotic and immature mechanisms showed no significant changes during therapy. The increased use of the mature mechanism can be an indicator of improvement in OCD treatment, showing that patients intensified their more adaptive responses to conflicts.

Maternal hsa-miR-423-5p associated with the cognitive development of babies in pregnant women without mental disorders.

Background: MicroRNAs (miRNAs) are small non-coding RNAs capable of regulating gene expression post-transcriptionally. MiRNAs are recognized as key regulators of diverse biological and developmental processes. During the pregnancy-puerperal cycle, numerous changes occur in the female body for the formation, growth, and development of the baby. After birth, there is a critical period in child development, as rapid gains in the physical, cognitive, and socio-emotional domains constitute the "building blocks" of children's later growth. Objective: The aim of this study was to investigate the association between maternal expression of hsa-miR-423-5p during the first and second trimesters of pregnancy and neurocognitive development at 90 days of life in infants. Methods: This is a longitudinal study included in a population-based cohort study, carried out in a city in southern Brazil. The Bayley III was used to assess the babies' cognitive development. Blood samples from mothers were obtained for RNA extraction from serum and analysis of miRNA expression by qRT-PCR. Results: In total, 87 dyads (mother-baby) were included. The average gestational age was 15.86 weeks (SD ± 5.55). An association of maternal miRNA with infant cognitive development was found; as maternal miR-423-5p increases, infants' cognitive development increases by 2.40 (95% CI 0.37; 4.43, p = 0.021) points at 3 months of age. Conclusion: In this context, it is suggested to use this miRNA as a biomarker of child neurocognitive development detectable in the prenatal period, thus allowing the planning of early interventions.

Environmental sustainability assessment of biodegradable bio-based poly(3-hydroxybutyrate-co-3-hydroxyvalerate) from agro-residues: Production and end-of-life scenarios.

In the context of a circular bio-based economy, more public attention has been paid to the environmental sustainability of biodegradable bio-based plastics, particularly plastics produced using emerging biotechnologies, e.g. poly(3-hydroxybutyrate-co-3-hydroxyvalerate) or PHBV. However, this has not been thoroughly investigated in the literature. Therefore, this study aimed to address three aspects regarding the environmental impact of PHBV-based plastic: (i) the potential environmental benefits of scaling up pellet production from pilot to industrial scale and the environmental hotspots at each scale, (ii) the most favourable end-of-life (EOL) scenario for PHBV, and (iii) the environmental performance of PHBV compared to benchmark materials considering both the pellet production and EOL stages. Life cycle assessment (LCA) was implemented using Cumulative Exergy Extraction from the Natural Environment (CEENE) and Environmental Footprint (EF) methods. The results show that, firstly, when upscaling the PHBV pellet production from pilot to industrial scale, a significant environmental benefit can be achieved by reducing electricity and nutrient usage, together with the implementation of better practices such as recycling effluent for diluting feedstock. Moreover, from the circularity perspective, mechanical recycling might be the most favourable EOL scenario for short-life PHBV-based products, using the carbon neutrality approach, as the material remains recycled and hence environmental credits are achieved by substituting recyclates for virgin raw materials. Lastly, PHBV can be environmentally beneficial equal to or even to some extent greater than common bio- and fossil-based plastics produced with well-established technologies. Besides methodological choices, feedstock source and technology specifications (e.g. pure or mixed microbial cultures) were also identified as significant factors contributing to the variations in LCA of (bio)plastics; therefore, transparency in reporting these factors, along with consistency in implementing the methodologies, is crucial for conducting a meaningful comparative LCA.

Translation, reliability, and validity of the Brazilian-Portuguese version of the Early Activity Scale for Endurance (EASE).

PURPOSE: Translate, investigate reliability, and construct validity of the Brazilian Early Activity Scale for Endurance (EASE). MATERIALS AND METHODS: Translation followed the international guidelines. Test-retest reliability was tested by 100 parents of children with cerebral palsy (CP): 18 months-5 years and 6-11 years. To determine construct validity, 94 parents of typically children completed the EASE. Statistical analysis included Bland-Altman, Intraclass Correlation Coefficient (ICC), Internal Consistency, and Floor and Ceiling Effect. RESULTS: The majority of the sample consisted of children with CP in GMFCS (IV-V). EASE showed good test-retest reliability for younger (ICC = 0.8) and excellent test-retest reliability for older children with CP (ICC = 0.9), and good internal consistency of 0.7 and 0.8 for the young and older group, respectively. Bland-Altman showed the bias close to zero, with no ceiling or floor effect. Regarding construct validity, younger children showed lower scores when compared to the older children. Endurance differed significantly between children with CP who were walking and those who were not walking and also for age groups. Children with CP showed lower endurance compared to typically participants in the same age group. CONCLUSIONS: Brazilian EASE is reliable and valid to estimate endurance in children with CP. Results provide evidence of construct validity.

Endurance to physical activity is an important construct to be evaluated and that directly interferes with the health and quality of life of children with Cerebral Palsy (CP).The Brazilian-Portuguese version of the 4-item Early Activity Scale for Endurance (EASE) is a valid and reliable scale to assess endurance to physical activity in children with CP.

Two cases of testicular tuberculosis in HIV patients with distinct clinical presentations.

Genito-urinary tuberculosis (TB) corresponds to the second most common cause of extrapulmonary tuberculosis EPTB worldwide. It is however rare and is often clinically indistinguishable from testicular malignancy and infarction. HIV hugely increases the risk of TB in unusual sites; we present two such cases of testicular tuberculosis. The diagnosis was based respectively on histopathological findings, acid-bacilli smear of biopsy, semen, and culture.

Maternidade distante do país de origem: "aqui a gente não tem uma aldeia" / Maternity far from the country of origin: "here we do not have a village" / Maternidad lejos del país de origen: "aquí no tenemos pueblo"

O presente estudo é um recorte de uma pesquisa mais ampla sobre a experiência da maternidade de mulheres brasileiras migrantes. Ele tem como objetivo investigar o apoio recebido por elas no processo de tornar-se mãe. Trata-se de uma pesquisa qualitativa na qual foram realizadas, em 2022, sete entrevistas com mulheres brasileiras que vivenciaram gestação, parto e primeiro ano de vida do filho (a) em Portugal, Reino Unido, Itália, Espanha e França. Os resultados apontam para a relevância da presença de pessoas que compartilham da mesma cultura de origem na construção da maternidade e na rede de apoio durante a perinatalidade. Conclui-se que o distanciamento da rede familiar, de amigos e de referenciais da cultura de origem da mulher migrante gerou o aumento das sobrecargas psíquica e física inerentes à maternidade. Ao mesmo tempo, de acordo com as participantes, o distanciamento da família e da cultura de origem proporcionou maior liberdade e abertura para a construção da maternidade, provendo novas representações culturais que contribuíram para a construção de sua forma de ser mãe.(AU)

This study is a segment of a broader research project on the maternity experience of Brazilian migrant women. It aims to investigate the support received by these women in the process of becoming mothers. It encompasses a qualitative research study involving seven interviews conducted in 2022 with Brazilian women who experienced pregnancy, childbirth, and the first year of their child's life in Portugal, the United Kingdom, Italy, Spain, and France. The findings highlight the importance of having individuals sharing the same cultural background in the construction of motherhood and in the support network during the perinatal period. The distance from the family network, friends, and references of the migrant woman's culture of origin generated an increase in the psychic and physical burdens inherent to motherhood. Simultaneously, according to the participants, distancing from family and their cultural origins provided greater freedom and openness in constructing motherhood, offering new cultural representations that contributed to shaping their way of being mothers.

Early motor development: risk factors for delay in a population study in Southern Brazil.

OBJECTIVE: To assess risk factors associated with motor development delay at three months of age. METHODS: Cross-sectional study with mothers and their three-month-old babies in Southern Brazil. The Bayley-III Scale of Infant and Toddler Development (BSID-III) and the Alberta Infant Motor Scale (AIMS) were used to assess motor development. RESULTS: We evaluated 756 mothers and their three-month-old babies. The overall mean motor development assessed by the BSID-III and the AIMS was 104.7 (SD 13.5) and 55.4 (SD 25.4), respectively. When assessed by the BSID-III, the lowest motor development scores were among babies born by cesarean delivery (p = 0.002), prematurely (p < 0.001), and with low birth weight (p < 0.001). When assessed by the AIMS, babies born prematurely (p = 0.002) and with low birth weight (p=0.004) had the lowest motor development means. After a cluster analysis, we found that babies born by cesarean delivery, with low birth weight, and prematurely had more impaired motor development compared with children born without any risk factors. CONCLUSION: Identifying risk factors allows the implementation of early interventions to prevent motor development delay and, therefore, reduce the probability of other future problems.

Development of an image-based fluorometer with smartphone control for paper analytical devices.

This work describes the construction and evaluation of a fluorometer for use in paper analytical devices, using a smartphone to operate the instrument and to perform real-time image-based detection. In this approach, a circular PAD containing twenty analytical plates is rotated at 18° increments under a UV LED source, providing a sequential irradiation of plates and the detection of the luminescence with a lab-made application, capable of automatically identifying the analytical zones and collecting the RGB intensities from the selected pixels. As a proof of concept, the fluorometer performance was evaluated for the determination of quinine in beverages and riboflavin (B2 vitamin) in supplements. Quinine, which is less photoreactive, provided steady-state signals, while riboflavin, which rapidly degrades under UV photons, presented transient responses for RGB detection. For both analytes, linear calibration ranges (R2 > 0.99) were observed from 2.0 mg L-1 to 10.0 mg L-1 with limits of detection estimated at approximately 1.0 mg L-1. Nevertheless, it was demonstrated that successive additions of standard solutions to a single analytical plate of PAD could enhance the signal-to-noise ratios for less concentrated samples, acting as a pre-concentration step. In addition, suitable deviations for the signals (ca. 4.0%) and the absence of systematic errors for most samples (9 out of 11), when compared with a reference method at 95% confidence level, indicates that the proposed strategy is precise and accurate enough to be used as analytical tool for fluorescence detection in PAD.

Preparation of Porous Scaffold Based on Poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate) and FucoPol.

This work focused on the development of porous scaffolds based on biocomposites comprising two biodegradable and biocompatible biopolymers: a terpolyester, poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate) (PHBHVHHx), and the bacterial polysaccharide FucoPol. The PHBHVHHx terpolymer was composed of 3-hydroxybutyrate (55 wt%), 3-hydroxyvalerate (21 wt%), and 3-hydroxyhexanoate (24 wt%). This hydrophobic polyester has low crystallinity and can form elastic and flexible films. Fucopol is a fucose-containing water-soluble polysaccharide that forms viscous solutions with shear thinning behavior and has demonstrated emulsion-forming and stabilizing capacity and wound healing ability. Emulsion-templating was used to fabricate PHA-based porous structures in which FucoPol acted as a bioemulsifier. Compared with the scaffolds obtained from emulsions with only water, the use of FucoPol aqueous solutions resulted in structures with improved mechanical properties, namely higher tensile strength (4.4 MPa) and a higher Young's Modulus (85 MPa), together with an elongation at break of 52%. These features, together with the scaffolds' high porosity and pore interconnectivity, suggest their potential to sustain cell adhesion and proliferation, which is further supported by FucoPol's demonstrated wound healing ability. Therefore, the developed PHBHVHHx:FucoPol scaffolds arise as innovative porous bioactive structures with great potential for use in tissue engineering applications.

Screen time: Implications for early childhood cognitive development.

BACKGROUND: Exposure and introduction to digital media, especially in children, are a current cause for concern. The negative links associated with early screen exposure are extensive. AIMS: To evaluate the association between the time of exposure to a screen in children at 18 months of age and cognitive development in a population-based sample in Southern Brazil. STUDY DESIGN: This was a cross-sectional study corresponding to the fourth wave of a population-based cohort study with pregnant women and later, their children living in the city of Pelotas, Southern Brazil. SUBJECTS: The sample consisted of 470 children who completed the cognitive assessment. OUTCOME MEASURES: Cognitive development was assessed using the Bayley Scales of Infant Development - Third Edition (BSID-III). Exposure to screen time was assessed using a questionnaire completed by the primary caregiver. RESULTS: Of the total, 58.8 % of the children had ≥1 h of screen time per day and the average on the cognitive scale of the entire sample was 96.1 (SD = 14.0). Cognitive development was lower in children whose mothers had lower levels of education (CI 95 % -4.9; -2.1), where boys (CI 95 % 3.2; 8.4) and in children exposed to 2 h or more of screen time/day (CI 95 % -3.6; -0.5). CONCLUSIONS: Exposure to screens may have a significant negative association with children's cognitive development and, therefore, we seek to intervene and to give advice to parents and guardians about the true impact of digital media. Further studies are necessary to consolidate the findings and to disclose information on the topic.

Gitelman Syndrome: A Case Report.

Gitelman syndrome is a rare hereditary tubulopathy characterized by hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria. In this case report, we describe a 21-year-old male who presented with myalgias, asthenia, general muscle weakness, and hypokalemia after receiving oral potassium supplementation for six months. Additional biochemical studies showed hypomagnesemia, metabolic alkalosis, and increased urinary potassium and magnesium excretion. Calcium urinary excretion was within the normal range, but 25-hydroxycholecalciferol levels were low. Systolic arterial hypertension was found, probably reflecting chronic hyperreninemic hyperaldosteronism. Genetic testing for SCL12A3 mutations identified a pathogenic variant in homozygosity, which confirmed the Gitelman syndrome diagnosis. Treatment with chronic potassium and magnesium oral supplementation was started, as well as eplerenone and amiloride, with sustained correction of hypokalemia and hypomagnesemia.

Can glutathione be a biomarker for suicide risk in women 18 months postpartum?

Background: Suicide risk is prominent among the problems affecting populations, mainly due to the broad family, psychosocial and economic impact. Most individuals at suicidal risk have some mental disorder. There is considerable evidence that psychiatric disorders are accompanied by the activation of neuro-immune and neuro-oxidative pathways. The aim of the study is to evaluate the serum levels of oxidative stress biomarkers in women at risk of suicide after 18 months of postpartum. Methods: This is a case-control study, nested within a cohort study. From this cohort, 45 women [15 without mood disorders and 30 with mood disorders (Major depression and Bipolar disorder)] were selected at 18 months postpartum, the depression and suicide risk were assessed using the Mini-International Neuropsychiatric Interview Plus (MINI-Plus) instrument, module A and C, respectively. Blood was collected and stored for later analysis of the reactive species (DCFH), superoxide dismutase (SOD), and glutathione reduced (GSH). For data analysis, the SPSS program was used. To compare the nominal covariates with the outcome GSH levels, the Student's t-test or analysis of variance (ANOVA) was used. Spearman's correlation was performed for analysis between the quantitative covariates and the outcome. To analyze the interaction between the factors, multiple linear regression was performed. Bonferroni analysis was used as an additional/secondary result to visualize differences in glutathione levels according to risk severity. After the adjusted analysis, p-values < 0.05 were considered statistically significant. Results: The percentage of suicide risk observed in our sample of women at 18 months postpartum was 24.4% (n = 11). After adjusting for the independent variables, only the presence of suicide risk remained associated with the outcome (ß = 0.173; p = 0.007), low levels of GSH at 18 months after postpartum. Likewise, we verified the difference in GSH levels according to the degree of suicide risk, observing a significant association between the differences in glutathione means in the group of women with moderate to high risk compared to the reference group (no suicide risk) (p = 0.009). Conclusion: Our findings suggest that GSH may be a potential biomarker or etiologic factor in women at moderate to high risk of suicide.

Advancing PHBV Biomedical Potential with the Incorporation of Bacterial Biopigment Prodigiosin.

The quest for sustainable biomaterials with excellent biocompatibility and tailorable properties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high production costs and the lack of bioactivity limit their market penetration. To address this, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was combined with a bacterial pigment with strong anticancer activity, prodigiosin (PG), to obtain functionally enhanced PHBV-based biomaterials. The samples were produced in the form of films 115.6-118.8 µm in thickness using the solvent casting method. The effects of PG incorporation on the physical properties (morphology, biopolymer crystallinity and thermal stability) and functionality of the obtained biomaterials were investigated. PG has acted as a nucleating agent, in turn affecting the degree of crystallinity, thermal stability and morphology of the films. All samples with PG had a more organized internal structure and higher melting and degradation temperatures. The calculated degree of crystallinity of the PHBV copolymer was 53%, while the PG1, PG3 and PG3 films had values of 64.0%, 63.9% and 69.2%, respectively. Cytotoxicity studies have shown the excellent anticancer activity of films against HCT116 (colon cancer) cells, thus advancing PHBV biomedical application potential.

Can Biomass Mastication Assist the Downstreaming of Polyhydroxyalkanoates Produced from Mixed Microbial Cultures?

Polyhydroxyalkanoates (PHAs) are natural polyesters which biodegrade in soils and oceans but have more than double the cost of comparable oil-based polymers. PHA downstreaming from its biomass represents 50% of its overall cost. Here, in an attempt to assist downstreaming, mastication of wet biomasses is tested as a new mechanical continuous biomass pretreatment with potential for industrial upscaling. Downstreaming conditions where both product recovery and purity are low due to the large amount of treated wet biomass (50% water) were targeted with the following process: extraction of 20 g in 100 mL solvent at 30 °C for 2 h, followed by 4.8 h digestion of 20 g in 0.3 M NaOH. Under the studied conditions, NaOH digestion was more effective than solvent extraction in recovering larger PHA amounts, but with less purity. A nearly 50% loss of PHA was seen during digestion after mastication. PHAs downstreamed by digestion with large amounts of impurities started to degrade at lower temperatures, but their melt elasticity was thermally stable at 170 °C. As such, these materials are attractive as fully PHA-compatible processing aids, reinforcing fillers or viscosity modifiers. On the other hand, wet biomass mastication before solvent extraction improves PHA purity and thermal stability as well as the melt rheology, which recovers the viscoelasticity measured with a PHA extracted from a dried biomass.

Maternal expression of miR-let-7d-3p and miR-451a during gestation influences the neuropsychomotor development of 90 days old babies: "Pregnancy care, healthy baby" study.

INTRODUCTION: Studies on maternal microRNA expression have emerged to better understand regulatory mechanisms during the gestational period, since microRNA expression has been associated with pregnancy disorders. OBJECTIVES: This study aims to investigate the association between the expression of the maternal microRNAs miR-let-7d-3p and miR-451a during the second gestational trimester and neuropsychomotor development at 90 days of life of infants. METHODS: This is a case-control study nested within a cohort, with the groups being divided into dyads in which pregnant women presented Major Depressive Episode (MDE) (n = 64), these being the cases, and their respective controls (no MDE; n = 64). The Bayley Scale III was used to assess the outcome of child development, and MDE was assessed through the Mini International Neuropsychiatric Interview Plus. The analysis of miR-let-7d-3p and miR-451a was done via serum from the pregnant women, utilizing the qRT-PCR (n = 128). RESULTS: The results indicated a negative association between expression levels of miR-451a (ß -3.3 CI95% -6.4;-0.3) and a positive associated of the miR-let-7d-3p with the cognitive development domain (ß 1.7 CI95% 0.1; 3.0), and a positive association between expression of miR-let-7d-3p with motor development of the infants (ß 1.6 CI95% 0.3; 2.9). CONCLUSION: This is a pioneering study on the topic that indicates a biological interrelationship between the miRNAs miR-let-7d-3p and miR-451a evaluated during the pregnancy and the motor and cognitive domains of infant development at 90 days postpartum.

Development of a layered bacterial nanocellulose-PHBV composite for food packaging.

BACKGROUND: Most of the current materials used in food packaging are synthetic and non-degradable, raising environmental issues derived from the accumulation of plastics in landfills/waterways. The food industry increasingly needs eco-friendly sustainable materials that meet food-packaging requirements. Bacterial nanocellulose (BNC), a biopolymer obtained by fermentation, offers very good mechanical properties and the ability to carry and deliver active substances. However, its water-vapor permeability is too high for food-packaging applications. In this work, a layered biodegradable composite based on BNC and polyhydroxyalkanoate (PHBV) was produced, attempting to improve its overall barrier properties. Polyhydroxyalkanoate is a biopolymer with high degree of hydrophobicity and biodegradability, and is also obtained by fermentation. Wet BNC membranes produced by static culture were plasticized by impregnation of solutions of either glycerol (BNCgly ) or polyethylene glycol (MW 600) (BNCPEG ). The plasticized BNC was then coated with PHBV solution dissolved in formic acid, and oven dried at 148 °C. RESULTS: Overall, PHBV coating on plasticized BNC reduced water vapor permeability significantly (from 0.990 to 0.032 g.µm.m-2 .day-1 .Pa-1 ) under 50% relative humidity. It increased the hydrophobicity (contact angle from 10-40° to 80-90°) but decreased the stiffness (from 3.1 GPa to 1.3 Gpa) of the composite. CONCLUSIONS: Overall, the mechanical and barrier properties of the layered composite obtained were considered suitable for food-packaging applications. The plasticizing (with glycerol or polyethylene glycol) of BNC significantly improved the mechanical performance and the PHBV coating reduced the water affinity (vapor and liquid state) on BNC. © 2022 Society of Chemical Industry.

Effectiveness of Physical Therapy Interventions in Children with Brachial Plexus Birth Injury: A Systematic Review.

AIM: To systematically review the effectiveness of physical therapy interventions in infants, children and adolescents with brachial plexus birth injury (BPBI). METHODS: Systematic review of randomized controlled trials including patients under 18 years old with BPBI was conducted on Medline, Cochrane, Embase, Amed and Pedro databases. Methodological quality was assessed by the PEDro score and quality of evidence by the GRADE system. The primary outcomes measured were range of motion, muscle strength and bone mineral density. RESULTS: Seven studies were included, two in infant and 5 in children, of 932 title and abstracts screened. The interventions, characteristics of the participants and outcomes were diverse. The largest effect was found when other intervention was combined with conventional physical therapy in the primary outcomes, with low quality of evidence. CONCLUSION: Physical therapy interventions alone or in combination with other treatment modalities are effective in improving short-term disabilities in children with BPBI.
