Effect of anti-Ebola virus monoclonal antibodies on endogenous antibody production in survivors of Ebola virus disease in the Democratic Republic of the Congo: an observational cohort study.

BACKGROUND: The use of specific anti-Ebola virus therapy, especially monoclonal antibodies, has improved survival in patients with Ebola virus disease. We aimed to assess the effect of monoclonal antibodies on anti-Ebola virus antibody responses in survivors of the 2018-20 Ebola outbreak in the Democratic Republic of the Congo. METHODS: In this observational prospective cohort study, participants were enrolled at three Ebola survivor clinics in Beni, Mangina, and Butembo (Democratic Republic of the Congo). Eligible children and adults notified as survivors of Ebola virus disease (ie, who had confirmed Ebola virus disease [RT-PCR positive in blood sample] and were subsequently declared recovered from the virus [RT-PCR negative in blood sample] with a certificate of recovery from Ebola virus disease issued by an Ebola treatment centre) during the 2018-20 Ebola virus disease outbreak were invited to participate in the study. Participants were recruited on discharge from Ebola treatment centres and followed up for 12-18 months depending on recruitment date. Routine follow-up assessments were done at 1, 3, 6, and 12-18 months after inclusion. We collected sociodemographic (age, sex, visit site), clinical (anti-Ebola virus drugs), and laboratory data (RT-PCR and Ct values). The primary outcome was the antibody concentrations against Ebola virus glycoprotein, nucleoprotein, and 40-kDa viral protein antigens over time assessed in all participants. Antibody concentrations were measured by the multiplex immunoassay, and the association between anti-Ebola virus antibody levels and the relevant exposures, such as anti-Ebola virus disease drugs (ansuvimab, REGN-EB3, ZMapp, or remdesivir), was assessed using both linear and logistic mixed regression models. This study is registered at ClinicalTrials.gov, NCT04409405. FINDINGS: Between April 16, 2020, and Oct 18, 2021, 1168 survivors were invited to participate in the Les Vainqueurs d'Ebola cohort study. 787 survivors were included in the study, of whom 358 had data available for antibody responses. 85 (24%) of 358 were seronegative for at least two Ebola virus antigens on discharge from the Ebola treatment centre. The antibody response over time fluctuated but a continuous decrease in an overall linear evolution was observed. Quantitative modelling showed a decrease in nucleoprotein, glycoprotein, and VP-40 antibody concentrations over time (p<0·0001) with the fastest decrease observed for glycoprotein. The probability of being seropositive for at least two antigens after 36 months was 53·6% (95% CI 51·6-55·6) for participants who received ansuvimab, 73·5% (71·5-75·5) for participants who received REGN-EB3, 76·8% (74·8-78·8) for participants who received remdesivir, and 78·5% (76·5-80·5) for participants who received ZMapp. INTERPRETATION: Almost a quarter of survivors were seronegative on discharge from the Ebola treatment centre and antibody concentrations decreased rapidly over time. These results indicate that monoclonal antibodies might negatively affect the production of anti-Ebola virus antibodies in survivors of Ebola virus disease which could increase the risk of reinfection or reactivation.

Durability of the Efficacy and Safety of Dolutegravir-Based and Low-Dose Efavirenz-Based Regimens for the Initial Treatment of Human Immunodeficiency Virus Type 1 Infection in Cameroon: Week 192 Data of the NAMSAL-ANRS-12313 Study.

Background: A prospective study was extended to the new antiretroviral and monitoring strategies in HIV-infected adults in low-income countries (NAMSAL-ANRS)-12313 trial, a 96-week open-label, multicenter, randomized phase 3 trial comparing dolutegravir (DTG) 50 mg with efavirenz 400 mg (EFV400), both administered with tenofovir disoproxil fumarate and lamivudine (TDF/3TC) as first-line treatment for antiretroviral therapy (ART)-naive people living with human immunodeficiency virus type 1 (HIV). Noninferiority of DTG to EFV400 was demonstrated at 48-week and sustained at 96 weeks. Here, we present results at 192-week. Methods: Previous trial participants were reconsented and followed up on their initial randomization arm (1:1 DTG/TDF/3TC:EFV400/TDF/3TC). Assessments included changes in viral suppression, biological parameters, and new serious adverse events (SAEs). Results: Among the participants enrolled in the trial, 81% (499/613) were analyzed at week 192: 84% (261/310) on DTG/TDF/3TC and 78% (238/303) on EFV400/TDF/3TC. HIV RNA suppression was maintained in 69% (214/310) on DTG/TDF/3TC-based and 62% (187/303) on EFV400/TDF/3TC-based regimens (difference, 7.3% [95% confidence interval, -.20 to 14.83]; P = .057). Five (DTG/TDF/3TC = 2; EFV400/TDF/3TC = 3) new viral failures (World Health Organization definition) without related resistance DTG mutations and 24 new SAEs were observed (DTG/TDF/3TC = 13; EFV400/TDF/3TC = 11). Mean weight gain was +9.4 kg on DTG/TDF/3TC and +5.9 kg on EFV400/TDF/3TC. The percentage of participants with obesity increased from 6.9% to 27.7% on DTG/TDF/3TC (P < .0001) and from 8.3% to 16.7% on EFV400/TDF/3TC (P = .0033). Conclusions: Four-year follow-up of people with HIV on DTG- and EFV400-based regimens showed long-term efficacy and safety of both ARTs, markedly among participants on DTG/TDF/3TC with high baseline viral load. However, unexpected substantial weight gain over time was prominent among participants on DTG/TDF/3TC, which should be closely monitored. Clinical Trials Registration. NCT02777229.

Risks of metabolic syndrome in the ADVANCE and NAMSAL trials.

Introduction: The ADVANCE and NAMSAL trials evaluating antiretroviral drugs have both reported substantial levels of clinical obesity in participants. As one of the main risk factors for metabolic syndrome, growing rates of obesity may drive metabolic syndrome development. This study aims to evaluate the risk of metabolic syndrome in the ADVANCE and NAMSAL trials. Methods: The number of participants with metabolic syndrome was calculated at baseline and week 192 as central obesity and any of the following two factors: raised triglycerides, reduced HDL-cholesterol, raised blood pressure and raised fasting glucose. Differences between the treatment arms were calculated using the χ2 test. Results: Across all visits to week 192, treatment-emergent metabolic syndrome was 15% (TAF/FTC + DTG), 10% (TDF/FTC + DTG) and 7% (TDF/FTC/EFV) in ADVANCE. The results were significantly higher in the TAF/FTC + DTG arm compared to the TDF/FTC/EFV arm (p < 0.001), and the TDF/FTC + DTG vs. the TDF/FTC/EFV arms (p < 0.05) in all patients, and in females. In NAMSAL, the incidence of treatment-emergent metabolic syndrome at any time point was 14% (TDF/3TC + DTG) and 5% (TDF/3TC + EFV) (p < 0.001). This incidence was significantly greater in the TDF/3TC/DTG arm compared to the TDF/3TC/EFV arm in all patients (p < 0.001), and in males (p < 0.001). Conclusion: In this analysis, we highlight treatment-emergent metabolic syndrome associated with dolutegravir, likely driven by obesity. Clinicians initiating or monitoring patients on INSTI-based ART must counsel for lifestyle optimisation to prevent these effects.

Improvements in Patient-Reported Outcomes Following Initiation of Dolutegravir-Based or Low-Dose Efavirenz-Based First-Line Antiretroviral Therapy: A Four-Year Longitudinal Analysis in Cameroon (NAMSAL ANRS 12313 Trial).

BACKGROUND: We provide new and comprehensive evidence on the evolution of a wide range of patient-reported outcomes (PROs) in the NAMSAL ANRS 12313 trial in Cameroon (2016-2021)-the first randomized comparison of dolutegravir 50 mg (DTG) and low-dose efavirenz (ie, 400 mg; EFV400) in treatment-naive adults living with HIV-1 in sub-Saharan Africa. METHODS: We first described the evolution of PROs between baseline and week 192. Then, we used random-effects models to measure the effect of time since the initiation of antiretroviral therapy and the differential effect of DTG versus EFV400 on each PRO, adjusting for clinical, demographic, and socioeconomic factors, while accounting for unobserved heterogeneity and missing data. RESULTS: Among the 613 patients randomized (DTG arm, n = 310; EFV400 arm, n = 303), (1) physical and mental health-related quality of life improved by 13.3% and 6.8%, respectively, (2) the percentage of patients with depression, anxiety, and stress decreased from 23.3%, 23.0%, and 7.7% to 3.1%, 3.5%, and 0.4%, respectively, and (3) the mean number of HIV-related symptoms decreased from 7.2 to 3.0 ( P < 0.001). For most PROs, no significant difference was found between both arms, even when accounting for the effect of DTG on weight gain. Nevertheless, our results suggest smaller improvements in mental health outcomes in the DTG arm, with a 5 percentage point higher adjusted probability of having anxiety at week 192 ( P < 0.01). CONCLUSIONS: Although supporting the current World Health Organization guidelines recommending DTG-based and EFV400-based regimens as preferred and alternative first-line antiretroviral therapy, further studies should investigate medium-term mental health outcomes in patients on DTG.

Reply to: "The partner-an underutilized facilitator to support healthy gestational weight gain".

Facilitators and barriers influencing weight management behaviours were identified in our meta-synthesis of qualitative research entitled "Facilitators and barriers influencing weight management behaviours during pregnancy: a meta-synthesis of qualitative research". This manuscript is in response to the letter submitted by Sparks et al. regarding that work. The authors highlight the importance of including partners into intervention design when addressing weight management behaviours. We agree with the authors that it is important to include partners into intervention design and further research is granted to identify facilitators and barriers affecting their influence over women. As per our findings, the influence of the social context goes beyond the partner and we suggest that future interventions should address other relevant people in women's contexts such as parents, other relatives, and close friends.

Insect chaperones Hsp70 and Hsp90 cooperatively enhance toxicity of Bacillus thuringiensis Cry1A toxins and counteract insect resistance.

Bacillus thuringiensis (Bt) produces different insecticidal proteins effective for pest control. Among them, Cry insecticidal proteins have been used in transgenic plants for the control of insect pests. However, evolution of resistance by insects endangers this technology. Previous work showed that the lepidopteran insect Plutella xylostella PxHsp90 chaperone enhanced the toxicity of Bt Cry1A protoxins by protecting them from degradation by the larval gut proteases and by enhancing binding of the protoxin to its receptors present in larval midgut cells. In this work, we show that PxHsp70 chaperone also protects Cry1Ab protoxin from gut proteases degradation, enhancing Cry1Ab toxicity. We also show that both PxHsp70 and PxHsp90 chaperones act cooperatively, increasing toxicity and the binding of Cry1Ab439D mutant, affected in binding to midgut receptors, to cadherin receptor. Also, insect chaperones recovered toxicity of Cry1Ac protein to a Cry1Ac-highly resistant P. xylostella population, NO-QAGE, that has a disruptive mutation in an ABCC2 transporter linked to Cry1Ac resistance. These data show that Bt hijacked an important cellular function for enhancing its infection capability, making use of insect cellular chaperones for enhancing Cry toxicity and for lowering the evolution of insect resistance to these toxins.

A systematic review of behaviour change techniques used in the context of stillbirth prevention.

BACKGROUND: Stillbirth is one of the most devastating pregnancy outcomes that families can experience. Previous research has associated a wide range of risk factors with stillbirth, including maternal behaviours such as substance use, sleep position and attendance and engagement with antenatal care. Hence, some preventive efforts have been focused on tackling the behavioural risk factors for stillbirth. This study aimed to identify the Behaviour Change Techniques (BCTs) used in behaviour change interventions tacking behavioural risk factors for stillbirth such as substance use, sleep position, unattendance to antenatal care and weight management. STUDY DESIGN: A systematic review of the literature was conducted in June 2021 and updated in November 2022 in five databases: CINHAL, Psyhinfo, SociIndex, PubMed and Web of Science. Studies published in high-income countries describing interventions designed in the context of stillbirth prevention, reporting stillbirth rates and changes in behaviour were eligible for inclusion. BCTs were identified using the Behaviour Change Technique Taxonomy v1. RESULTS: Nine interventions were included in this review identified in 16 different publications. Of these, 4 interventions focused on more than one behaviour (smoking, monitoring fetal movements, sleep position, care-seeking behaviours), one focused on smoking, three on monitoring fetal movements and one on sleep position. Twenty-seven BCTs were identified across all interventions. The most commonly used was "Information about health consequences" (n = 7/9) followed by "Adding objects to the environment" (n = 6/9). One of the interventions included in this review has not been assessed for efficacy yet, of the remaining eight, three showed results in the reduction of stillbirth rates. and four interventions produced behaviour change (smoking reductions, increased knowledge, reduced supine sleeping time). CONCLUSIONS: Our findings suggest that interventions designed to date have limited effects on the rates of stillbirth and utilise a limited number of BCTs which are mostly focused on information provision. Further research is necessary to design evidence base behaviour change interventions with a greater focus to tackle all the other factors influencing behaviour change during pregnancy (e.g.: social influence, environmental barriers).

Intervención educativa sobre la COVID-19 en los trabajadores del Centro de Investigaciones Científicas de la Defensa Civil / Educational intervention on COVID-19 in the personnel of the Civil Defense Scientific Research Center

Introducción: La COVID-19 creó desafíos sin precedentes para la comunidad y los trabajadores de la salud, por lo que contribuir a incrementar la percepción del riesgo mediante la capacitación fue una premisa elemental en tiempos de la pandemia. Objetivo: La investigación tuvo la finalidad de contribuir a incrementar el conocimiento en aspectos importantes sobre la COVID-19 en los trabajadores del Centro de Investigaciones Científicas de la Defensa Civil. Métodos: Se realizó una evaluación antes y después de la intervención en el período de febrero a abril de 2021. La muestra estuvo conformada por 50 trabajadores divididos en dos grupos: 1) investigadores y técnicos; 2) personal de apoyo. La investigación se desarrolló en tres etapas: diagnóstico, intervención y evaluación. Se conformó una base de datos con la información recopilada y para su análisis se empleó el método de comparación de proporciones de las respuestas entre los grupos, antes y después de la evaluación. Se calculó el porcentaje de apropiación de conocimientos con nivel de significación (p < 0,05) y se aplicó el t-Student para muestras dependientes. Resultados: De 50 trabajadores 35 (70 %) eran del sexo femenino; predominó el nivel escolar universitario con un total de 33 (66 %). Se observó un incremento estadísticamente significativo, tanto en la apropiación del conocimiento en ambos grupos, como en las preguntas adecuadas, después de la intervención (p < 0,05); siendo superior en el grupo del personal de apoyo. Conclusiones: La intervención educativa contribuyó a incrementar los conocimientos acerca de la COVID-19 en los trabajadores del centro, lo que tuvo un impacto favorable.

Introduction: COVID-19 created unprecedented challenges for the community and health workers; therefore, contributing to increase risk perception through training was an elementary premise in times of the pandemic. Objective: The research aimed at increasing the knowledge of important aspects of COVID-19 among the personnel of the Civil Defense Scientific Research Center. Methods: An evaluation was carried out before and after the intervention from February to April 2021. The sample consisted of 50 workers divided into two groups: 1) researchers and technicians; 2) support personnel. The research comprised three stages: diagnosis, intervention, and evaluation. A database was created with the information collected. For its analysis, the compare proportions test of responses between the groups, before and after the evaluation, was used. The percentage of knowledge appropriation was calculated with significance level (p < 0.05), and the t-Student was applied for dependent samples. Results: Out of 50 workers, 35 (70%) were female; 33 (66%) had a university education level. A statistically significant increase in both knowledge acquisition and appropriate questions was observed in the groups after the intervention (p < 0.05), which was higher in the support staff group. Conclusions: The educational intervention contributed to increasing knowledge about COVID-19 among the workers of the center, which had a favorable impact.

Exploring first-time mothers' experiences and knowledge about behavioural risk factors for stillbirth.

BACKGROUND: Modifiable factors such as substance use, lack of attendance at antenatal care, overweight or obesity and sleeping position are associated with a higher risk of stillbirth. This qualitative study aimed to explore women's experiences of modifiable factors during pregnancy and their awareness of stillbirth. METHODS: Purposive sampling was implemented by hospital staff in a large tertiary maternity hospital in Ireland between November 2020 and March 2021. Women were approached during their stay in the hospital and were invited to participate in a semistructured interview 3-5 months later. Eligible women were primiparous, >18 years of age and had an uncomplicated pregnancy and delivery. Eighteen women who consented to be followed up were interviewed at 3-5 months postpartum. Thematic analysis was used to analyse the data. RESULTS: Four themes were identified: attitudes towards behaviour change, awareness regarding stillbirth and risk factors, the silence around stillbirth and risks, and attitudes towards receiving information about stillbirth. Women spoke about behaviour change in terms of outcomes, and most changes (e.g., ceasing alcohol consumption) were perceived as easy to manage. Awareness of stillbirth was limited among the women interviewed, and the association between risk behaviours and stillbirth was not known by any woman. Results suggest that there is a silence around stillbirth, including in antenatal care, which hinders information provision. However, most women highlighted the value of receiving information and extra education about modifiable risk factors and stillbirth. CONCLUSION: There is a general lack of understanding of the link between behavioural risk factors and potential pregnancy outcomes such as stillbirth. Providing further information to women about stillbirth and providing additional support with behaviour change might contribute to enhancing preventive efforts. PATIENT OR PUBLIC CONTRIBUTION: Patients were involved in this study by providing their experiences of antenatal care which were used as primary data.

The association of trait emotional intelligence with the levels of anxiety, stress and physical activity engagement of adolescents / La asociación entre la inteligencia emocional rasgo con los niveles de ansiedad, el estrés y la práctica de actividad física de los adolescentes

Abstract Introduction: Emotional intelligence is considered a protective and facilitating factor for physical and mental health. The aims of the present study are to define and compare an explanatory model of trait emotional intelligence, anxiety, stress and physical activity engagement, as well as to analyse existing relationships between the aforementioned variables as a function of gender. Method: The present study was descriptive and cross-sectional in nature, employing a sample of 2452 Spanish adolescents (age range = 13-16 years of age). A multi-group model of structural equations was developed which presented an excellent fit. Results: For both genders, a negative association was detected between emotional intelligence and anxiety levels. A direct positive association emerged between trait emotional intelligence and physical activity engagement, in addition to a positive association between anxiety and stress. In boys, a negative association existed between trait emotional intelligence and stress levels, as well as an indirect negative association between physical activity engagement and trait anxiety. In girls, an indirect negative association was observed between physical activity engagement and stress levels. Conclusions: Trait emotional intelligence is positively associated with physical activity engagement. Further, both variables are negatively associated with levels of anxiety and stress, with some differences emerging as a function of gender.

Resumen Introducción: La inteligencia emocional se considera un factor protector y facilitador de la salud física y mental. Por ello, los objetivos de este artículo son definir y contrastar un modelo explicativo sobre la inteligencia emocional rasgo, los niveles de ansiedad, el estrés y la práctica de actividad física, así como analizar las relaciones existentes entre dichas variables en función del género. Método: Se trata de un estudio de tipo descriptivo y corte transversal con una muestra de 2452 adolescentes españoles de ambos géneros (rango de edad = 13 a 16 años). Se realizó un modelo de ecuaciones estructurales multigrupo que se ajustó de forma excelente. Resultados: En ambos géneros, se encuentra una asociación negativa entre inteligencia emocional rasgo y niveles de ansiedad; una asociación positiva y directa entre inteligencia emocional rasgo y práctica de actividad física, así como una asociación positiva entre la ansiedad y estrés. En hombres existe una asociación negativa entre inteligencia emocional rasgo y niveles de estrés, así como una asociación negativa e indirecta entre la práctica de actividad física y la ansiedad rasgo. En mujeres se observa una asociación negativa e indirecta entre práctica de actividad física y los niveles de estrés. Conclusiones: La inteligencia emocional rasgo se asocia positivamente con la práctica de actividad física, ambas variables se asocian de forma negativa con los niveles de ansiedad y estrés y se encuentran algunas diferencias en función del género.

Facilitators and barriers to seeking and engaging with antenatal care in high-income countries: A meta-synthesis of qualitative research.

Inadequate attendance to antenatal care has been associated with negative maternal and fetal outcomes, including stillbirth. This study aimed to identify facilitators and barriers to antenatal care attendance. A systematic search was conducted in March 2019 and updated in January 2021. Qualitative studies involving pregnant or post-partum women up to 12 months from high-income countries that provided data about facilitators and barriers to antenatal care attendance were sought. Meta-ethnography was used to inform this meta-synthesis. Fifteen studies were included in the analysis. Findings indicate that inadequate antenatal care attendance is influenced at different levels. Aspects like sociodemographic factors, difficulties navigating the health system, administrative delays, lack of flexibility and tailored care, constant change of carer and communication issues also act as barriers. These issues affect women's access to knowledge and the formation of women's beliefs and feelings towards seeking care. On the contrary, having a positive attitude towards the pregnancy, encountering empathetic healthcare professionals and availing of social support acted as facilitators. The reasons why women seek or delay attending antenatal care are multifactorial and can be explained using the Social Determinants of Health Framework. Any response needs to be taken across all levels of influence and not just focused on the individual. A better understanding of the barriers and facilitators to antenatal care might contribute to informing intervention or policy development addressing this issue.

Facilitators and barriers influencing weight management behaviours during pregnancy: a meta-synthesis of qualitative research.

BACKGROUND: Obesity and overweight are considered risk factors for a range of adverse outcomes, including stillbirth. This study aims to identify factors reported by women influencing weight management behaviours during pregnancy. METHODS: A systematic search was conducted in five databases from inception to 2019 and updated in 2021. Qualitative studies involving pregnant or post-partum women, from high-income countries, examining women's experiences of weight management during pregnancy were included. Meta-ethnography was used to facilitate the meta-synthesis of 17 studies. RESULTS: Three themes were identified during the analysis: (1) Awareness and beliefs about weight gain and weight management, which included level of awareness and knowledge about dietary and exercise recommendations, risk perception and decision balance, perceived control over health and weight gain and personal insecurities. (2) Antenatal healthcare, women's experiences of their interactions with healthcare professionals during the antenatal period and the quality of the education received had an effect on women's behaviour. Further, our findings highlight the need for clear and direct information, and improved interactions with healthcare professionals, to better support women's weight management behaviours. (3) Social and environmental influence, the social judgement and stigmatization associated with overweight and obesity also acted as a negative influence in womens' engagement in weight management behaviours. CONCLUSION: Interventions developed to promote and maintain weight management behaviours during pregnancy should consider all levels of influence over women's behaviours, including women's level of awareness and beliefs, experiences in antenatal care, education provision and social influence.

Ganglioneuroma de mediastino posterior: a propósito de un caso

RESUMEN Los tumores de origen neuroectodérmico son la principal causa de tumores de mediastino. De ellos el ganglioneuroma es el de mayor benignidad y el menos frecuente, con una incidencia de 1 en 100,000 niños. Ocurre predominantemente en la infancia con una media de presentación a los siete años. La mayor parte de estos tumores cursan asintomáticos y son diagnosticados de manera incidental. El 43 % de ellos tienen manifestación intratorácica y están localizados en los ganglios simpáticos del mediastino posterior. Los medios de diagnóstico por imágenes aportan ventajas para mostrar la localización, tamaño y extensión del tumor. Estos exámenes resultan de gran beneficio para el cirujano. El pronóstico es generalmente favorable, lo que constituye signo de buen pronóstico, la aparición posterior a los cinco años de edad y las localizaciones en el mediastino posterior. Se presenta el caso de una paciente a la que se le realizó toracoscopia con resección total del tumor, con evolución favorable durante su seguimiento. A esta paciente se le diagnosticó un ganglioneuroma en mediastino posterior. Se realizó una revisión bibliográfica a propósito de este caso. Se presenta este reporte porque el ganglioneuroma es un tumor benigno poco frecuente en edad pediátrica.

ABSTRACT Neuroectodermal tumors are the main cause of mediastinal tumors. Of these, the ganglioneuroma is the most benign and the least frequent, with an incidence of 1 in 100,000 children. It occurs predominantly in childhood with a mean presentation at age seven. Most of these tumors are asymptomatic and diagnosed incidentally. The 43 % of them showing intrathoracic manifestation and located in the sympathetic ganglia of the posterior mediastinum. Imaging studies provide advantages for the location, size and extent of the tumor. These tests are of great benefit to the surgeon. The prognosis is generally favorable, which is a sign of good prognosis when it appears after five years of age and when it is located in the posterior mediastinum. The case of a patient who underwent thoracoscopy with total resection of the tumor, with a favorable evolution during her follow-up is presented. This patient was diagnosed with a ganglioneuroma in the posterior mediastinum. A literature review was carried out regarding this case. This report is presented because ganglioneuroma is a rare benign tumor in children.

Facilitators and barriers to substance-free pregnancies in high-income countries: A meta-synthesis of qualitative research.

BACKGROUND: Previous studies have associated substance use (alcohol, illicit drugs and smoking) to negative pregnancy outcomes, including higher risk of stillbirth. AIM: This study aims to identify facilitators and barriers reported by women to remain substance free during pregnancy. METHODS: A systematic search was conducted in six databases from inception to March 2019 and updated in November 2020. Qualitative studies involving pregnant or post-partum women, from high-income countries, examining women's experiences of substance use during pregnancy were eligible. Meta-ethnography was used to facilitate this meta-synthesis. FINDINGS: Twenty-two studies were included for analysis. Internal barriers included the perceived emotional and social benefits of using substances such as stress coping, and the associated feelings of shame and guilt. Finding insensitive professionals, the lack of information and discussion about risks, and lack of social support were identified as external barriers. Furthermore, the social stigma and fear of prosecution associated with substance use led some women to conceal their use. Facilitators included awareness of the health risks of substance use, having intrinsic incentives and finding support in family, friends and professionals. DISCUSSION: Perceived benefits, knowledge, experiences in health care settings, and social factors all play important roles in women's behaviours. These factors can co-occur and must be considered together to be able to understand the complexity of prenatal substance use. CONCLUSION: Increased clinical and community awareness of the modifiable risk factors associated with substance use during pregnancy presented in this study, is necessary to inform future prevention efforts.

Amyand's hernia, case report and review of current literature

ABSTRACT Introduction: Amyand's hernia (appendix trapped within an inguinal hernia) is a rare clinical condition that groups two common surgical diseases: acute appendicitis and inguinal hernia. Its preoperative diagnosis is difficult, so it should be considered in cases of inguinal hernia before an inflammatory process occurs in the appendix to avoid complications. Although there is no consensus on its treatment, current classifications serve as a guide for a timely surgical resolution. Case presentation: A 57-year-old male patient from the southern coast of Ecuador consulted the emergency department of a secondary level health care institution due to a 24-hour history of painful and irreducible mass in the right inguinal region associated with hyporexia. The patient was diagnosed with incarcerated inguinal hernia and underwent a right inguinal hernioplasty, during which the appendix and cecum were found inside the hernia sac. Hernioplasty and appendectomy were performed using the Lichtenstein technique. The patient was discharged in good conditions and did not have any complications at 8- and 15-day follow-up. Conclusions: Amyand's hernia is increasingly reported. It is difficult to diagnose preoperatively due to its nonspecific symptoms. When suspected, imaging studies help its visualization and guide an individualized and early treatment, together with the current classifications of this type of hernias.

RESUMEN Introducción. La hernia de Amyand es una condición clínica infrecuente que agrupa a dos patologías quirúrgicas habituales: apendicitis aguda y hernia inguinal; en esta entidad el apéndice vermiforme se encuentra en el interior del saco de una hernia inguinal. Su diagnóstico preoperatorio es difícil, por lo que debe tenerse en cuenta en casos de hernia inguinal antes de que se presente un proceso inflamatorio, el cual puede traer más complicaciones; además, aunque no existe un consenso para el manejo según las clasificaciones actuales, estas sirven de guía para una resolución quirúrgica oportuna. Presentación del caso. Hombre de 57 años procedente de la costa sur de Ecuador, quien consultó al servicio de emergencias de una institución de segundo nivel de atención por un cuadro clínico de 24 horas de evolución que inició con la aparición de una masa dolorosa e irreductible en la región inguinal derecha asociada a hiporexia. El paciente fue diagnosticado con hernia inguinal incarcerada y se le practicó una hernioplastia inguinal derecha en la que se encontró el apéndice y el ciego dentro del saco herniario; durante este procedimiento también se realizó apendicectomía y hernioplastia con técnica de Lichtenstein. El paciente fue dado de alta en buenas condiciones y en controles posteriores, a los 8 y 15 días de la cirugía, no presentó complicaciones. Conclusiones. La hernia de Amyand es una entidad cada vez más frecuente que tiene un difícil diagnóstico preoperatorio debido a su cuadro clínico inespecífico. Ante la sospecha de esta patología se deben realizar estudios de imagenología que ayuden a su visualización y orienten, junto con las clasificaciones actuales de este tipo de hernias, un manejo individualizado y temprano.

Evaluación nutricional y fuerza muscular medida por dinamometría en pacientes con fibrosis quística en un centro de adultos / Nutritional assessment and muscle strength measured by dynamometry in patients with cystic fibrosis in an adult center

Introducción: en la Fibrosis Quística (FQ) el compromiso pancreático, la malabsorción, la inflamación crónica de bajo grado, el aumento del gasto energético por el trabajo respiratorio y el desarrollo de diabetes relacionada con FQ (DRFQ) predisponen a la desnutrición, siendo el seguimiento nutricional parte fundamental del tratamiento. Objetivos: evaluar el estado nutricional de pacientes con FQ en un centro de adultos en la primera consulta del 2019. Evaluar asociación entre la fuerza muscular (FM) con otros parámetros nutricionales y con la función pulmonar. Materiales y método: estudio transversal, observacional, en 30 pacientes. La FM se evaluó con dinamómetro digital. Para determinar masa grasa y masa muscular se utilizó pliegue tricipital y circunferencia muscular braquial. Para función pulmonar: volumen espiratorio forzado (VEF1). Análisis estadístico con programa SPSS 20.0: Chi-cuadrado y T-Student (p<0.05). Resultados: mediana de edad 22 años (RIQ = 19,75; 27,25), 36,7% mujeres. El 76,7% tenía insuficiencia pancreática exocrina (IPE), de ellos 39,1% DRFQ. Del total, 30% presentó FM disminuida. Si bien el 80% tenía índice de masa corporal (IMC) ≥18,5 kg/m2, sólo el 20% alcanzó un IMC deseable. 50% presentó masa muscular disminuida y 46,7% masa grasa disminuida. Se encontró asociación estadísticamente significativa entre la FM y las siguientes variables: masa muscular (p=0,001); bajo peso (p=0,001); DRFQ (p=0,008) (OR:12, IC 95% 1,89 - 76,15) y masa grasa (p=0,046) (OR:7, IC 95% 1,14-42,96). Menor VEF1 (p=0,017) y menor IMC (p=0,002) se asociaron con FM. No se halló asociación estadísticamente significativa entre FM e IPE. Conclusión: la FM disminuida en pacientes con FQ es frecuente y se relacionó con masa muscular y adiposa disminuidas, bajo peso, DRFQ y función pulmonar. Hacen falta más estudios, obteniendo datos comparables del estado nutricional en centros de atención especializados. La evaluación nutricional es parte del seguimiento integral, realizarla de manera exhaustiva y protocolizada, incluyendo análisis de composición corporal y FM resulta de gran importancia para la toma de decisiones.

Introduction: in Cystic Fibrosis (CF) the pancreatic involvement, malabsorption, chronic inflammation, increased energy expenditure due to respiratory work, and the development of CF-Related Diabetes (CFRD) predispose to malnutrition, thus nutritional monitoring is essential. Objectives: to assess the nutritional status of CF patients in an adult center at the first medical appointment in 2019. To evaluate the association between muscular strength (MS) and other nutritional parameters and pulmonary function. Materials and method: cross-sectional, observational, in 30 patients. MS was evaluated with digital dynamometer. Triceps skinfold and arm muscle circumference were used to determine adipose mass and muscle mass. For pulmonary function: forced expiratory volume in 1 second (FEV1). Statistical analysis with SPSS 20.0 program: Chi-square and T-Student (p <0.05). Results: median age of 22 years old (IQR= 19,75; 27,25), 36,7% women. 76,7% had exocrine pancreatic insufficiency (EPI), of which 39,1% CFRD. Of the total, 30% presented decreased MS. Although 80% had body mass index (BMI) ≥18,5kg/m2, only 20% reached a desirable BMI. 50% presented decreased muscle mass and 46,7% decreased adipose mass. A statistically significant association was found between MS and the following variables: muscle mass (p=0,001); low weight (p=0,001); CFRD (p=0,008) (OR:12, CI 95% 1,89; 76,15) and adipose mass (p=0,046) (OR:7, CI 95% 1,14; 42,96). Lower FEV1 (p=0.017) and lower BMI (p=0.002) were associated with MS. No statistically significant association was found between decreased MS and EPI. Conclusion: decreased MS in CF patients is common and was associated with decreased muscle and adipose mass, low weight, CFRD, and pulmonary function. More studies are needed, so as to obtain comparable data on the nutritional status in specialized care centers. Nutritional assessment is an integral part of monitoring; carrying it out exhaustively and protocolized, including body composition analysis and MS is of great importance for decision making.

Satisfaction with Self and External Regulation of Learning in Higher Education Students in Brazil.

The satisfaction of university students with the variables that regulate their learning provides very valuable information to improve the quality of teaching processes. The main objective of this study was to evaluate the learning of Brazilian university students, exploring both self-regulation variables, such as study techniques; and more external regulation variables, namely, satisfaction with the teaching-learning process and with the infrastructure, based on three variables: gender, the institution of higher education and the academic year of the students. To achieve this, 560 students of the Pedagogy degree were evaluated with two questionnaires: a questionnaire of satisfaction with the educational infrastructure and the teaching-learning process and a questionnaire on study techniques. Statistically significant differences were obtained, especially depending on the type of institution and the academic year. The students of private schools and earlier academic years were the ones who obtained the most satisfaction with the study techniques and with the infrastructure. Those from private centers also expressed more satisfaction with the teaching-learning processes. These results provide greater knowledge about the processes of self-regulation and external regulation of university learning and of their satisfaction with them, which can contribute to improving educational policies in Brazil.

Cost-Utility Analysis of a Dolutegravir-Based Versus Low-Dose Efavirenz-Based Regimen for the Initial Treatment of HIV-Infected Patients in Cameroon (NAMSAL ANRS 12313 Trial).

OBJECTIVES: Evidence comparing the economic and patient values of the World Health Organization's preferred (dolutegravir 50 mg [DTG]-based) and alternative (low-dose [400 mg] efavirenz [EFV400]-based) first-line antiretroviral regimens is limited. We compared patient-reported outcomes (PROs), costs, and the cost-utility of DTG- versus EFV400-based regimens in treatment-naive HIV-1 adults in the randomised NAMSAL ANRS 12313 trial in Yaoundé, Cameroon. METHODS: We used clinical data, PROs, and health resource use data collected in the trial's first 96 weeks (2016-2019). Quality-adjusted life-years (QALYs) were computed using utility scores obtained from the 12-item Short Form (SF-12) generic health scale. Other PROs included perceived symptoms, depression, anxiety, and stress. In the 96-week base-case analysis, we estimated the unadjusted and multivariate-adjusted (1) mean costs (in US$, 2016 values) and QALYs/patient, (2) incremental costs and QALYs/patient, and (3) net health benefit (NHB). Outcomes were extrapolated over 5 and 10 years. Uncertainty was assessed using the cost-effectiveness acceptability curve and scenario and cost-effective price threshold analyses. RESULTS: In the base-case analysis, the NHB (95% confidence interval) for the DTG-based regimen relative to the EFV400-based regimen was 0.056 (- 0.037 to 0.153), corresponding to an 88% probability of DTG being cost-effective. A 10% decrease in this regimen's price (from $5.2 to $4.7/month) would increase its cost-effectiveness probability to 95%. When extrapolating outcomes over 5 and 10 years, the DTG-based regimen had a 100% probability of being cost-effective for a large range of cost-effectiveness thresholds. CONCLUSIONS: At 2020 antiretroviral drug prices, a DTG-based first-line regimen should be preferred over an EFV400-based regimen in sub-Saharan Africa.

A protocol for a systematic review of behaviour change techniques used in the context of stillbirth prevention.

Background: Stillbirth is a devastating pregnancy outcome that affects approximately 3.5 per 1000 births in high-income countries. Previous research has highlighted the importance of focusing prevention efforts on targeting risk factors and vulnerable groups. A wide range of risk factors has been associated with stillbirth before, including maternal behaviours such as back sleep position, smoking, alcohol intake, illicit drug use, and inadequate attendance at antenatal care. Given the modifiable nature of these risk factors, there has been an increase in the design of behaviour change interventions targeting such behaviours to reduce the risk of stillbirth. Objectives: The aim of this study is to identify all behavioural interventions with a behavioural component designed and trialled for the prevention of stillbirth in high-income countries, and to identify the behaviour change techniques (BCTs) used in such interventions using the Behaviour Change Techniques Taxonomy V1 (BCTTv1). Inclusion criteria: Interventions will be included in this review if they (1) have the objective of reducing stillbirth rates with a focus on behavioural risk factors; (2) are implemented in high-income countries; (3) target pregnant women or women of childbearing age; and (4) are published in research articles. Methods: A systematic search of the literature will be conducted. The results of the search will be screened against our inclusion criteria by two authors. The following data items will be extracted from the selected papers: general information, study characteristics, participant and intervention/approach details. The Cochrane Effective Practice and Organization of Care (EPOC) risk of bias criteria will be used to assess the methodological quality of included studies. Intervention content will be coded for BCTs as present (+) or absent (-) by two authors using the BCTTv1, discrepancies will be discussed with a third author. A narrative synthesis approach will be used to present the results of this systematic review.
