RESUMO

SUMMARY OBJECTIVE: The aim of this study was to investigate the role of systemic immune-inflammation index, neutrophil-lymphocyte ratio, lymphocyte-monocyte ratio, and platelet-lymphocyte ratios calculated in the first trimester as inflammatory markers in predicting gestational diabetes mellitus diagnosis. METHODS: This study was conducted retrospectively at a tertiary center between January 2020 and June 2023. A total of 111 pregnant women with gestational diabetes and 378 pregnant women in the control group were included in the study. Systemic immune-inflammation index, neutrophil-lymphocyte ratio, lymphocyte-monocyte ratio, and platelet-lymphocyte ratios values were compared between the gestational diabetes mellitus group patients and the healthy group. Receiver operating characteristic analysis curve was used for predicting gestational diabetes mellitus using systemic immune-inflammation index and lymphocyte-monocyte ratio. RESULTS: In pregnant women in the first trimester, systemic immune-inflammation index and lymphocyte-monocyte ratio values based on routine complete blood count parameters were found to be statistically significantly higher in gestational diabetes mellitus patients compared to healthy patients, while neutrophil-lymphocyte ratio and platelet-lymphocyte ratios values were found to be similar (p=0.033, p=0.005, p=0.211, and p=0.989). For predicting gestational diabetes mellitus, a cut-off value of 655.75 for systemic immune-inflammation index resulted in 80.2% sensitivity and 34.4% specificity, and a cut-off value of 3.62 for lymphocyte-monocyte ratio resulted in 56.8% sensitivity and 63.2% specificity, indicating good discriminatory ability. CONCLUSION: We believe that systemic immune-inflammation index and lymphocyte-monocyte ratio values measured in the first-trimester complete blood count parameters are effective in predicting gestational diabetes mellitus but are not effective in determining insulin requirement.

RESUMO

Temperature and nutrition are suggested as the primary factors affecting larval survival during the transition from endogenous to exogenous feeding in fish. However, little is known about its simultaneous impact during this period. In this study, Seriola rivoliana eggs were subjected to a constant 24 °C (CTE) and a daily temperature fluctuation (DTF) between 22.8 and 25.2 °C until oil droplet exhaustion (5.5 days after hatching). On the other hand, marine fish larvae mostly rely on live feed, with certain nutritional deficiencies such as poor long-chain fatty acids. Thus, rotifer Brachionus rotundiformis enrichment was simultaneously evaluated with temperature using three enrichment diets: Ori-green, S.presso, and a Domestic emulsion. For this purpose, the five experimental groups were established in triplicate using six 100-L tanks with three 10-L containers inside (18 experimental units in total). One hundred eggs were incubated, using a green water system, and 10 rotifers mL-1 were offered at mouth opening. After oil droplet exhaustion, survival was only affected by temperature (P < 0.01), being higher at DTF compared to CTE. At the same stage, Domestic emulsion resulted in bigger larvae than Ori-green. In a further assay at 3.7 DAH, the relative expression of the trypsin gene was higher at Domestic emulsion compared to S.presso and Ori-green. This study indicates that daily temperature fluctuation can improve larval performance and low levels of EPA and DHA in Domestic emulsion enriched rotifers were not critical for Seriola rivoliana at first feeding.

RESUMO

INTRODUCTION: Breast cancer is still one of the main causes of cancer mortality in women worldwide, and death rates are even greater in vulnerable populations. A delay in diagnosis usually comes with advanced-stage disease, which impacts patient survival. The aim of this study was to evaluate the time for first medical consultation among women with breast cancer attending the Magdalena V. de Martínez Hospital and to determine the causes that may influence patient delay and its impact on cancer stage at diagnosis. MATERIALS AND METHODS: Three hundred and six breast cancer patients were interviewed using a self-report questionnaire, and socioeconomic and demographic variables, namely, highest education level completed, employment status and breast cancer awareness, were collected. The answers were associated with patient clinical records, such as clinical staging and tumor size. RESULTS: Forty-nine percent of the patients were diagnosed with advanced-stage disease. These women had either a deficiency in breast cancer awareness, did not visit a gynecologist after age 40 or, were unemployed, while those patients diagnosed with early-stage breast cancer had nonpalpable tumors, declared a sufficient household income or delayed less than four weeks in seeking medical attention. Moreover, the delay in the first medical visit was more than one month in 78% of the patients, being disregard the most common cause of postponement. Additionally, patient delays were associated with larger tumors and with incomplete education. DISCUSSION: These results indicate that early detection efforts should be made to reduce the disease stage at diagnosis, which may impact on overall survival.

Introducción: El cáncer de mama (CM) es una de las principales causas de mortalidad por cáncer en mujeres, y las tasas de mortalidad son aún mayores en poblaciones vulnerables. Un retraso en el diagnóstico suele acompañarse con estadios avanzados de la enfermedad, lo que impacta en la supervivencia del paciente. El objetivo fue evaluar el tiempo transcurrido para la primera consulta médica entre mujeres con CM que asisten al Hospital Magdalena V. de Martínez y determinar las causas que pueden influir en la demora del paciente y su impacto en el estadio al momento del diagnóstico. Materiales y métodos: Se entrevistaron 306 pacientes con CM utilizando un cuestionario autoinformado, y se recopilaron variables socioeconómicas y demográficas, entre ellas, nivel educativo más alto completado, situación laboral y conocimiento sobre el CM. Las respuestas se asociaron con los registros clínicos de las pacientes. Resultados: El 49% de las pacientes fueron diagnosticadas con enfermedad en estadios avanzados. Estas mujeres tenían deficiencias en el conocimiento sobre el CM, no consultó al ginecólogo después de los 40 años o estaba desempleada, mientras que aquellas diagnosticadas con CM en estadios tempranos tenían tumores no palpables, declaraban un ingreso familiar suficiente o demoraban menos de cuatro semanas en buscar atención médica. Además, la demora en la primera visita médica fue de más de un mes en el 78% de las pacientes, siendo el desinterés la causa más común de postergación. Asimismo, las demoras estaban asociadas con tumores más grandes y con una educación incompleta. Discusión: Este estudio sugiere la necesidad de desarrollar estrategias de sensibilización y educación sobre el CM, así como de políticas para mejorar el acceso a la atención médica, especialmente para poblaciones vulnerables, con el fin de reducir el retraso en el diagnóstico y mejorar la salud de las pacientes con CM.

RESUMO

BACKGROUND: Schizophrenia is a disorder associated with neurocognitive deficits that adversely affect daily functioning and impose an economic burden. Cognitive rehabilitation interventions, particularly during the early phases of illness, have been shown to improve cognition, functionality, and quality of life. The Feuerstein Instrumental Enrichment (FIE) program, based on the Mediated Learning Experience and the Structural Cognitive Modifiability theory, has been applied in various disorders, but its applicability in schizophrenia has not yet been clarified. OBJECTIVE: This study aims to investigate the effects of the FIE program on the functionality of patients with first-episode schizophrenia. METHODS: In total, 17 patients will be recruited for an open-label intervention consisting of twice-weekly sessions for 10 weeks. The primary outcome measure will be changes in the Goal Achievement Scale score. Maze task performance from the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) battery will serve as a secondary outcome measure. At the same time, changes in Positive and Negative Syndrome Scale scores and other MATRICS domains will be analyzed as exploratory outcomes. Assessments will be administered before and after the intervention, with a follow-up period of 6 months. RESULTS: This trial was preregistered in The Brazilian Registry of Clinical Trials (RBR-4gzhy4s). By February 2024, 11 participants were enrolled in the training. Recruitment is expected to be completed by May 2024. Data analysis will be conducted between May and September 2024. The results are expected to be published in January 2025. CONCLUSIONS: This study may establish a protocol for the FIE program that uses mediation techniques for individuals in the early stages of schizophrenia. The results will add to the knowledge about strategies to promote cognitive skills and functional impairment in daily life. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/57031.

RESUMO

BACKGROUND: Telemedicine represents an important strategy to facilitate access to medication abortion (MAB) procedures, reduces distance barriers and expands coverage to underserved communities. The aim is evaluating the self-managed MAB (provided through telemedicine as the sole intervention or in comparison to in-person care) in pregnant people at up to 12 weeks of pregnancy. METHODS: A literature search was conducted using electronic databases: MEDLINE, Embase, Cochrane (Central Register of Controlled Trials and Database of Systematic Reviews), LILACS, SciELO, and Google Scholar. The search was based on the Population, Intervention, Comparison, Outcome, and Study Design (PICOS) framework, and was not restricted to any years of publication, and studies could be published in English or Spanish. Study screening and selection, risk of bias assessment, and data extraction were performed by peer reviewers. Risk of bias was evaluated with RoB 2.0 and ROBIS-I. A narrative and descriptive synthesis of the results was conducted. Meta-analyses with random-effects models were performed using Review Manager version 5.4 to calculate pooled risk differences, along with their individual 95% confidence intervals. The rate of evidence certainty was based on GRADE recommendations. RESULTS: 21 articles published between 2011 and 2022 met the inclusion criteria. Among them, 20 were observational studies, and 1 was a randomized clinical trial. Regarding the risk of bias, 5 studies had a serious risk, 15 had a moderate risk, and 1 had an undetermined risk. In terms of the type of intervention, 7 compared telemedicine to standard care. The meta-analysis of effectiveness revealed no statistically significant differences between the two modalities of care (RD = 0.01; 95%CI 0.00, 0.02). Our meta-analyses show that there were no significant differences in the occurrence of adverse events or in patient satisfaction when comparing the two methods of healthcare delivery. CONCLUSION: Telemedicine is an effective and viable alternative for MAB, similar to standard care. The occurrence of complications was low in both forms of healthcare delivery. Telemedicine services are an opportunity to expand access to safe abortion services.

RESUMO

The aim of this study was to assess the impact of genotype-environment interaction (GEI) on the manifestation of traits such as age at first calving (AFC), age at first service (AFS), and calving interval (CI) through the application of the reaction norm model in Holstein cattle raised in Paraná state, Brazil. Utilizing data from the milk testing service of the Paraná Association of Holstein Cattle Breeders (APCBRH), this study analyzed records from 179,492 animals undergoing their first, second, and third lactations from the years 2012 to 2022. These animals were part of 513 herds spread across 72 municipalities in Paraná. The environmental gradient was established by normalizing contemporary group solutions, derived from the animal model, with the 305-day-corrected milk yield serving as the dependent variable. Subsequently, reaction norms were determined utilizing a Random Regression Model. Spearman's correlation was then applied to compare the estimates of breeding values across different environmental gradients for the studied traits. The highest EG (+ 4) indicates the least challenging environments, where animals experience better environmental conditions. Conversely, lower EG (-4) values represent the most challenging environments, where animals endure worse conditions. The only trait that exhibited a moderate heritability magnitude was AFC (0.23) in the least challenging environmental condition. The other traits were classified as having low heritability magnitudes regardless of the evaluated environmental gradient. While minimal evidence was found for the influence of GEI on CI, a clear GEI effect was observed for AFC and AFS across all environmental gradients examined. A reversal in genotype ranking occurred under extreme environmental conditions. The findings suggest that the best-performing genotype under one environmental gradient may not necessarily excel under another.

RESUMO

An increase in total drug (small molecules and biologics) approvals by the Food and Drug Administration (FDA) was seen in 2023 compared with the previous year. Cancer remained the disease most targeted by monoclonal antibodies (mAbs), followed by autoimmune conditions. Our data reveal the prevalence of approvals for biologics even during years when the total number of authorizations was low, such as in 2022. Over half the drugs that received the green light in 2023 benefited from expedited programs, as the incidence of many diseases increased. In addition, over half of the biologics approved received Orphan Drug Designation from the FDA. This narrative review delves into details of the most significant approvals in 2023, including mAbs, enzymes, and proteins, explaining their mechanisms of action, differences from previous drugs, placebo, and standards of care, and outcomes in clinical trials. Given the varying number of drugs authorized annually by the U.S. health authority, this review also examines the limits of external influences over the FDA's decisions and independence regarding drug approvals and withdrawals.

RESUMO

Objective: This study aimed to investigate the effects of the presence of subchorionic hematoma (SH) in early pregnancies with threatened miscarriage (TM) on levels of first-trimester maternal serum markers, pregnancy-associated plasma protein-A (PAPP-A), and free ß-human chorionic gonadotropin (ß-hCG) levels. Methods: The data of TM cases with SH in the first trimester between 2015 and 2021 were evaluated retrospectively. The data of age and gestational age-matched TM cases without SH were also assessed to constitute a control group. Demographic characteristics, obstetric histories, ultrasonographic findings, and free ß-hCG and PAPP-A levels of the groups were compared. Results: There were 119 cases in the study group and 153 cases in the control group. The median vertical and longitudinal lengths of the SH were 31 mm and 16 mm. The median age of both groups was similar (p=0.422). The MoM value of PAPP-A was 0.088 (.93) in the study group and 0.9 (0.63) in the control group (p=0.519). Similarly, the MoM value of free ß-hCG was 1.04 (0.78) in the study group and 0.99 (0.86) in the control group (p=0.66). No significant relationship was found in the multivariate analysis between free ß-hCG MoM, PAPP-A MoM, age, gravida, and vertical and longitudinal lengths of the hematoma (p>0.05). Conclusion: The level of PAPP-A and free ß-hCG were not affected by the SH. Therefore, these markers can be used reliably in TM cases with SH for the first-trimester fetal aneuploidy screening test.

RESUMO

It is recommended to implement the teaching of Basic Life Support (BLS) in schools; however, studies on the best training method are limited and have been a priority in recent years. The objective of this study was to analyze the attitudes and practical skills learned during BLS training using a gamified proposal. A comparative study was carried out, consisting of Compulsory Secondary Education students [control group (CG; classical teaching) and experimental group (EG; gamified proposal)]. The instruments used were the CPR and AED action sequence observation sheet, data from the Laerdal Resusci Anne manikin and AED and Attitude Questionnaire towards Basic Life Support and the Use of the Automated External Defibrillator. Sixty-eight students (33 girls) with a mean age of 13.91 ± 0.70 years were recruited. Results were significantly better in the EG (n = 37) [i.e., breathing control (p = 0.037); call to emergency services (p = 0.049); mean compression depth (p = 0.001); self-confidence (p = 0.006); intention to perform BLS and AED (p = 0.002)]; and significantly better in the CG (n = 31) [Total percentage of CPR (p < 0.001); percentage of correct compression (p < 0.001); time to apply effective shock with AED (p < 0.001); demotivation (p = 0.005). We can conclude that the group that was trained with the training method through the gamified proposal presents better intentions and attitudes to act in the event of cardiac arrest than those of the classic method. This training method allows for similar results in terms of CPR and AED skills to classical teaching, so it should be taken into account as a method for teaching BLS to secondary education students.

RESUMO

Background: Despite its popularity, evidence of the effectiveness of Psychological First Aid (PFA) is scarce.Objective: To assess whether PFA, compared to psychoeducation (PsyEd), an attention placebo control, reduces PTSD and depressive symptoms three months post-intervention.Methods: In two emergency departments, 166 recent-trauma adult survivors were randomised to a single session of PFA (n = 78) (active listening, breathing retraining, categorisation of needs, assisted referral to social networks, and PsyEd) or stand-alone PsyEd (n = 88). PTSD and depressive symptoms were assessed at baseline (T0), one (T1), and three months post-intervention (T2) with the PTSD Checklist (PCL-C at T0 and PCL-S at T1/T2) and the Beck Depression Inventory-II (BDI-II). Self-reported side effects, post-trauma increased alcohol/substance consumption and interpersonal conflicts, and use of psychotropics, psychotherapy, sick leave, and complementary/alternative medicine were also explored.Results: 86 participants (51.81% of those randomised) dropped out at T2. A significant proportion of participants in the PsyEd group also received PFA components (i.e. contamination). From T0 to T2, we did not find a significant advantage of PFA in reducing PTSD (p = .148) or depressive symptoms (p = .201). However, we found a significant dose-response effect between the number of delivered components, session duration, and PTSD symptom reduction. No significant difference in self-reported adverse effects was found. At T2, a smaller proportion of participants assigned to PFA reported increased consumption of alcohol/substances (OR = 0.09, p = .003), interpersonal conflicts (OR = 0.27, p = .014), and having used psychotropics (OR = 0.23, p = .013) or sick leave (OR = 0.11, p = .047).Conclusions: Three months post-intervention, we did not find evidence that PFA outperforms PsyEd in reducing PTSD or depressive symptoms. Contamination may have affected our results. PFA, nonetheless, appears to be promising in modifying some post-trauma behaviours. Further research is needed.

Psychological First Aid (PFA) is widely recommended early after trauma.We assessed PFA's effectiveness for decreasing PTSD symptoms and other problems 3 months post-trauma.We didn't find definitive evidence of PFA's effectiveness. Still, it seems to be a safe intervention.

RESUMO

Enteric viruses are responsible for a significant number of gastrointestinal illnesses in dogs globally. One of the main enteric viruses is the canine astrovirus (CaAstV), which causes diarrhea in dogs of various ages. It is linked to symptoms such as diarrhea, vomiting, depression and a significant mortality rate due to gastrointestinal disorders. It is a single-stranded positive RNA virus, with three open reading frames, ORF1a, ORF1b and ORF2, where the last one codes for the virus capsid protein and is the most variable and antigenic region of the virus. The aim of this work is to develop and standardize a quick detection method to enable the diagnosis of this etiological agent in dogs with gastroenteritis in Ecuador in order to provide prompt and suitable treatment. The assay was specific for amplification of the genome of CaAstV, as no amplification was shown for other canine enteric viruses (CPV-2, CCoV and CDV), sensitive by being able to detect up to one copy of viral genetic material, and repeatable with inter- and intra-assay coefficients of variation of less than 10% between assays. The standard curve showed an efficiency of 103.9%. For the validation of this method, 221 fecal samples from dogs affected with gastroenteritis of various ages from different provinces of Ecuador were used. From the RT-qPCR protocol, 119 samples were found positive for CaAstV, equivalent to 53.8% of the samples processed. CaAstV was detected in dogs where both the highest virus prevalence in the tested strains and the highest viral loads were seen in the younger canine groups up to 48 weeks; in addition, different strains of the virus were identified based on a sequenced fragment of ORF1b, demonstrating the first report of the presence of CaAstV circulating in the domestic canine population affected by gastroenteritis in Ecuador, which could be associated with the etiology and severity of enteric disease.

RESUMO

Introduction: It is known that cognitive deficits are a core feature of schizophrenia and that in the general population, prior beliefs significantly influence learning and reasoning processes. However, the interaction of prior beliefs with cognitive deficits and their impact on performance in schizophrenia patients is still poorly understood. This study investigates the role of beliefs and cognitive variables (CVs) like working memory, associative learning, and processing speed on learning processes in individuals with schizophrenia. We hypothesize that beliefs will influence the ability to learn correct predictions and that first-episode schizophrenia patients (FEP) will show impaired learning due to cognitive deficits. Methods: We used a predictive-learning task to examine how FEP (n = 23) and matched controls (n = 23) adjusted their decisional criteria concerning physical properties during the learning process when predicting the sinking behavior of two transparent containers filled with aluminum discs when placed in water. Results: On accuracy, initial differences by group, trial type, and interaction effects of these variables disappeared when CVs were controlled. The differences by conditions, associated with differential beliefs about why the objects sink slower or faster, were seen in patients and controls, despite controlling the CVs' effect. Conclusions: Differences between groups were mainly explained by CVs, proving that they play an important role than what is assumed in this type of task. However, beliefs about physical events were not affected by CVs, and beliefs affect in the same way the decisional criteria of the control or FEP patients' groups.

RESUMO

La calidad de atención primaria de salud parte desde la perspectiva individual del servicio recibido en cualquiera de los niveles de atención de salud. La presente investigación tuvo como finalidad identificar el tipo de experiencia de los adultos mayores que acuden al primer nivel de atención primaria del Centro de Salud Belén en el periodo junio - diciembre 2022. Con un enfoque cuantitativo en una población de 91 adultos mayores, a quienes se aplicó el Cuestionario Herramientas de Evaluación de Atención Primaria (PCAT ­ usuarios adultos) donde la experiencia ata en la calidad de atención dentro de la calificación general (≥ 6,6; < 6,6), obtuvo predominio en el sexo femenino 52,75% (n=48) con respecto al 47,25% (n=43) del sexo masculino. La confiabilidad del cuestionario empleado se midió utilizando la prueba estadística de alfa de Cronbach con un valor de 0.79, considerado aceptable. Con los resultados obtenidos se evidencian que la calificación global de la calidad de atención fue alta sin embargo, existen deficiencias en los atributos de la atención primaria dentro del centro, además de un predominio en la consulta de la población femenina con todos los grupos etarios acude con mayor frecuencia con respecto a la masculina (AU)

The quality of primary health care starts from the individual perspective of the service received at any of the levels of health care. The purpose of this research was to identify the type of experience of older adults who attend the first level of primary care at the Belén Health Center in the period June - December 2022. With a quantitative approach in a population of 91 older adults, whom The Primary Care Assessment Tools Questionnaire (PCAT ­ adult users) was applied where experience ties in the quality of care within the general rating (≥ 6.6; < 6.6), obtaining a predominance in the female sex 52,75% (n=48) compared to 47.25% (n=43) of the male sex . The reliability of the questionnaire used was measured using the Cronbach's alpha statistical test with a value of 0.79, considered acceptable. The results obtained showed that the overall rating of the quality of care was high, however, there are deficiencies in the attributes of primary care within the Belén Health Center, in addition to a predominance in the consultation of the female population with all the age groups attend more frequently compared to men (AU)

RESUMO

Background: Mental health problems represent a growing global concern. This has intensified since the coronavirus pandemic and is also partly due to greater awareness of the extent of mental health problems and the lack of attention they have received over time. In many high-income countries, increases in service provision have been accompanied by efforts to increase the mental health literacy of the general population. One example of this in Australia, is the mental health first aid training program which is informed by the mental health first aid guidelines created to promote mental health literacy among the general population, reduce stigma, and enable lay people to provide timely support, and facilitate access to health services for a person developing a mental health problem or in a mental health crisis. Methods: Between March 2020 and May 2023, a consortium of researchers from Australia, Argentina and Chile carried out the cultural adaptation of five guidelines (drinking problems, depression, suicide risk, trauma, and psychosis) using the Delphi consensus methodology. Health professionals with expertise in each of the topics and people with lived experience (their own or as informal caregivers) from Argentina and Chile were grouped into separate panels. Over two survey rounds, they evaluated the items from the Australian guidelines and gave their opinion on the importance of their inclusion in the local guidelines. Additionally, they suggested items not included in the Australian guidelines. Results: This report presents the details of the methodology used and the most significant results of each of the five adapted guidelines, particularly, those of relevance to the Argentinian and Chilean context. The general acceptance of the role of the first aider stands out as an important outcome. However, in comparison to Australia, the first aider's role was reduced and the health professional role was expanded. Self-help recommendations were typically not endorsed by local experts, suggesting skepticism toward these strategies. Other specific recommendations for each of the guidelines are described and analyzed in this report. Conclusions: A study of the implementation of training courses based on these guidelines is required to make the necessary adaptations and determine their local usefulness.

Introducción: Los problemas de salud mental en la comunidad representan una preocupación global creciente, intensificada desde la pandemia por coronavirus y gracias a una mayor conciencia respecto de su extensión y del bajo nivel de atención que recibieron a lo largo del tiempo. En Australia se crearon las primeras guías de primeros auxilios en salud mental para promover un mayor conocimiento de temas de salud mental en la población general, brindar apoyo oportuno, facilitar el acceso a los servicios de salud por esta problemática, y disminuir el estigma asociado al padecimiento mental. Método: Un consorcio de investigadores de Australia, Argentina y Chile, entre marzo de 2020 y mayo de 2023, realizó la adaptación cultural de cinco guías (consumo problemático de alcohol, depresión, riesgo de suicidio, trauma, y psicosis) siguiendo la metodología de consenso Delphi. Profesionales expertos en cada uno de los temas y personas con experiencia vivida  (propia o como cuidadores informales) conformaron sendos paneles con miembros de Argentina y de Chile. En dos rondas de consulta evaluaron los ítems provenientes de las guías de Australia y opinaron sobre su pertinencia para formar parte de las guías locales. Adicionalmente, sugirieron ítems que no estaban contemplados en las guías australianas. Resultados: El presente reporte presenta el detalle de la metodología empleada y los resultados más significativos de cada una de las cinco guías adaptadas y, particularmente, su aplicabilidad para Argentina y Chile. Sobresale la aceptación general del rol del asistente de primeros auxilios en salud mental, aunque también con limitaciones en el rol y funciones en favor del privilegio de profesionales de la salud. Las recomendaciones de auto-ayuda fueron mayoritariamente no aceptadas por los expertos locales, sugiriendo desconfianza respecto de estas estrategias. Otras recomendaciones específicas para cada una de las guías se describen y analizan en este reporte. Conclusiones: Se requiere un estudio de la implementación de la capacitación en base a estas guías para realizar ulteriores adaptaciones y determinar su utilidad local.

RESUMO

Low- middle-income countries (LMICs) are facing challenges for reaching outstanding performance on indicators related to wellbeing during the first 1000 days of life, therefore it is expected to observe difficulties for improving their Human Capital Index (HCI). These come from the impact of inadequate antenatal care, maternal short stature, inadequate breastfeeding, prematurity, low birthweight, small for gestational age newborns, and pregnancy in adolescent years on human capital from the first thousand days of life to long term on life. Therefore, the aim of this study was to implement a non-systematic review of the existing literature between February 2000 and October 2022 using MeSH terms related to each factor. Results: in LMICs antenatal care does not meet the required goals. High rate of adolescent pregnancies, and lower maternal stature are being reported; 6.5 million newborns in LMICs are small for gestational age, 50% LBW newborns are preterm. Exclusive breastfeeding is low in LMICs: 28-70%. Survival, schooling, and health are strongly associated with growth and adult height showing the impact of the disadvantages experienced in early life over HC. We can conclude: the determinants of good health in the first 1000 days of life do not meet the goals needed to improve growth and health during this critical period of life in LMICs, leading to important obstacles for achieving adequate health conditions and reaching an optimal HCI(AU)

Los países con bajo y medianos ingresos (PBMIs) enfrentan el reto de disminuir las brechas para alcanzar las metas en los indicadores de bienestar durante los primeros 1000 días de vida, de lo contrario presentarán dificultades para mejorar los Índices de Capital Humano (ICH). El objetivo fue realizar una revisión no sistemática de la literatura reciente para abordar los problemas, brechas y omisiones dentro de los primeros 1000 días en los países PBMIs. Se utilizaron los términos MeSH relacionados con los factores de riesgo de impacto más prevalentes a corto y largo plazo: capital humano, atención prenatal inadecuada, talla baja materna, lactancia materna inadecuada, prematuridad, bajo peso al nacer, talla pequeña para la edad gestacional, embarazo adolescente para realizar una revisión descriptiva sobre el impacto de estos factores, entre febrero 2000-octubre 2022. Resultados: en PBMIs la consulta prenatal no llega a la meta sugerida y hay tasas altas de adolescentes embarazadas y baja estatura materna. 6,5 millones de recién nacidos en PBMIs con peso para la edad gestacional; 50% recién nacidos bajos para la edad gestacional son pretérminos. La lactancia materna exclusiva es baja en PBMIs: 28-70%. La supervivencia, escolaridad y salud tienen una fuerte asociación con la estatura y desarrollo del adulto, demostrando el impacto de las desventajas sobre el Capital Humano. Conclusión: los determinantes de la buena salud durante los primeros 1000 días de vida en los países PBMIs no alcanzan las metas necesarias para mejorar el crecimiento y la salud, convirtiéndose en obstáculos para alcanzar óptimos ICH(AU)

RESUMO

Aim: To evaluate the spatial distribution of MIH opacities in first permanent molars (FPM). Materials and methods: an analysis of intraoral photographs of FPM with demarcated MIH opacities was conducted. The presence of opacity was computed in a digital matrix, discriminating the anatomical regions of the FPM surfaces. The frequencies of distribution of the opacities were descriptively analyzed through 227 FPM digital images of 89 children built in GIMP and Python and by Spearman correlation (= 0,05). Results: the occlusal surface was the most affected one (94% to 100%). In the upper FPM, the palatine surface was the second most affected one (84%-91%). In the lower FPM, the vestibular surface was the second most affected one (85%-80%). A similar pattern of opacity distribution was observed in the contralateral teeth. On smooth surfaces, opacities were more frequent in the regions closer to the occlusal surface than to the cervical one. Conclusion: MIH opacities were mostly present on occlusal, vestibular, and lingual/palatine surfaces, respectively. There is a possibility that the occurrences are in accordance with the chronology of dental formation.

RESUMO

This is the first record of Melanoloma viatrix Hendel as well as in its host (pineapple) in Brazil. Previously, M. viatrix had been found in pineapple plantations in Peru, Colombia, Venezuela, and Ecuador. In Brazil, this fly was initially reported in pineapple purchased from a commercial establishment in the municipality of Porto Grande, Amapá State, in 2020. Subsequently, M. viatrix was found in a commercial pineapple plantation, Ananas comosus (L.) Merr. cv. Pérola, also in Porto Grande, Amapá State. In the pineapple samples, 2,320 specimens of M. viatrix were collected on a single day on that rural property (approximately 2 ha). The larvae open galleries in the pulp that cause the pineapple to rot, making it unviable for consumption and commercial sale. This communication aims to alert phytosanitary authorities of the need to establish control strategies to prevent the spread of the pineapple fly to other states in Brazil.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the maternal and ultrasonographic characteristics of pregnant women who underwent cervical length (CL) measurement by transvaginal ultrasound between 11 and 13 + 6 weeks of gestation and who delivered at term or preterm. METHODS: A retrospective cohort study was carried out between March 2013 and December 2018 by analyzing ultrasound data of singleton pregnant women who underwent CL measurement by transvaginal ultrasound during the first trimester scan. CL was compared between the two groups (full-term and preterm birth [PB]) using Student's t-test. RESULTS: A total of 5097 pregnant women were enrolled, of whom 5061 (99.3%) had term and 36 (0.7%) had PB < 34 weeks. CL measurements did not differ between the term and preterm groups (36.62 vs. 37.83 mm, p = 0.08). Maternal age showed a significant and linear association with CL (r = 0.034, p = 0.012) and CRL (r = 0.086, p < 0.001). Smoking status was associated with shorter CL (36.64 vs. 35.09 mm, p = 0.003). When we analyzed the CL of the pregnant women in the term and preterm groups, according to the gestational age cut-offs for prematurity (28, 30, 32, and 34 weeks), we found that there was no significant difference between the measurements in all groups (p > 0.05). CONCLUSION: We observed no significant differences between CL measurements between 11 and 13 + 6 weeks in pregnant women who had preterm and term deliveries. Gestational age and CRL showed a significant and linear association with CL measurement.

RESUMO

INTRODUCTION: Schizophrenia is a debilitating disorder that affects a significant proportion of the population and leads to impaired functionality and long-term challenges. The first episode of psychosis (FEP) is a critical intervention stage for improving long-term outcomes. The GAPi program was established in São Paulo, Brazil to provide early intervention services and evaluate biomarkers in individuals with FEP. This article delineates the objectives of the GAPi program, detailing its innovative research protocol, examining the clinical outcomes achieved, and discussing the operational challenges encountered during its initial decade of operation. METHODS: The study comprised a prospective cohort of antipsychotic-naïve individuals with first-episode psychosis aged between 16 and 35 years. Participants were recruited from a public psychiatric facility in São Paulo. Emphasizing the initiative's commitment to early intervention, clinical assessments were systematically conducted at baseline and at two months, one year, two years, and five years of treatment to capture both short- and medium-term outcomes. Various assessment tools were utilized, including structured interviews, symptom scales, the Addiction Severity Index, and functional assessments. RESULTS: A total of 232 patients were enrolled in the cohort. Among them, 65.95 % completed the 2-month follow-up. Most patients presented with schizophrenia spectrum disorders, followed by bipolar disorder and major depressive disorder with psychotic features. Treatment response rates and remission rates were evaluated at different time points, with promising outcomes observed. The program also assessed socio-demographic factors, substance use, family history, and genetic and biomarker profiles, providing valuable data for research. DISCUSSION: The GAPi program has emerged as the largest ongoing cohort of antipsychotic-naïve first-episode psychosis in Latin America, contributing to the understanding of early psychosis in low- and middle-income countries. Despite operational challenges, the program has demonstrated efficacy in reducing the duration of untreated psychosis and in improving clinical outcomes. A multidisciplinary approach, including pharmacological treatment, psychosocial interventions, and family involvement, has been instrumental in enhancing treatment adherence and long-term prognosis. CONCLUSION: The GAPi program represents a valuable model for early intervention in first-episode psychosis and provides insights into the pathophysiology, treatment, and long-term outcomes of individuals with schizophrenia and related disorders. Continued research and resource allocation are essential for addressing operational challenges and expanding early intervention services in low- and middle-income countries.

RESUMO

Gestational diabetes mellitus (GDM) is a hyperglycemic state that is typically diagnosed by an oral glucose tolerance test (OGTT), which is unpleasant, time-consuming, has low reproducibility, and results are tardy. The machine learning (ML) predictive models that have been proposed to improve GDM diagnosis are usually based on instrumental methods that take hours to produce a result. Near-infrared (NIR) spectroscopy is a simple, fast, and low-cost analytical technique that has never been assessed for the prediction of GDM. This study aims to develop ML predictive models for GDM based on NIR spectroscopy, and to evaluate their potential as early detection or alternative screening tools according to their predictive power and duration of analysis. Serum samples from the first trimester (before GDM diagnosis) and the second trimester (at the time of GDM diagnosis) of pregnancy were analyzed by NIR spectroscopy. Four spectral ranges were considered, and 80 mathematical pretreatments were tested for each. NIR data-based models were built with single- and multi-block ML techniques. Every model was subjected to double cross-validation. The best models for first and second trimester achieved areas under the receiver operating characteristic curve of 0.5768 ± 0.0635 and 0.8836 ± 0.0259, respectively. This is the first study reporting NIR-spectroscopy-based methods for the prediction of GDM. The developed methods allow for prediction of GDM from 10 µL of serum in only 32 min. They are simple, fast, and have a great potential for application in clinical practice, especially as alternative screening tools to the OGTT for GDM diagnosis.
