Outpatient prescription of clozapine in Colombia: factors related to the use of doses lower than 100 mg/day / Prescripción ambulatoria de clozapina en Colombia: factores relacionados con el uso de dosis inferiores a 100 mg/día.

Although commonly used in clinical practice, scientific literature about clozapine prescription patterns in Colombia is scarce. A cross-sectional observational study was conducted in an outpatient clinic in Bogotá, Colombia. Between 2016 and 2018, clozapine was prescribed to 2603 patients, mainly for Schizophrenia Spectrum Disorders and Bipolar and Depressive Disorders, at a median dose of 100mg/day. After controlling for other variables, older age was the only variable that explained the use of doses lower than 100mg/day. Clozapine was not only used for Treatment-Resistant Schizophrenia, and further studies are needed to explain these differences.

Aunque se utiliza comúnmente en la práctica clínica, la literatura científica sobre los patrones de prescripción de clozapina en Colombia es escasa. Se realizó un estudio observacional transversal en el servicio ambulatorio de una clínica de referencia en Bogotá, Colombia. Entre 2016 y 2018, se recetó clozapina a 2603 pacientes, principalmente para esquizofrenia y trastornos relacionados, trastorno afectivo bipolar y trastornos depresivos, a una dosis media de 100 mg/día. Después de controlar otras variables, la edad avanzada fue la única variable que explicó el uso de dosis inferiores a 100 mg/día. La clozapina no se utilizó sólo para la esquizofrenia resistente al tratamiento, y se necesitan estudios adicionales para explicar estas diferencias.

Predictors of cognitive change in cognitively healthy older women in Panama: the PARI-HD study.

Background: Evidence suggests that a combination of biological and social factors influence risk of dementia differently for women and men. In healthy older women, several factors may contribute to changes in cognition. Objective: Describe the characteristics associated with variation in cognition in a sample of cognitively healthy older Panamanian women. Methods: The study includes cross-sectional analyses of cognitive domains at baseline (n = 357) and 17-month (SD = 2.0) follow-up (n = 200) for women aged 60 years and older enrolled in the Panama Aging Research Initiative-Health Disparities (PARI-HD) study. Instruments included clinical questionnaires, physiological measures, and a neuropsychological test battery assessing global cognition and seven cognitive domains. Multiple regression analyses examined the associations between demographic and clinical characteristics and cognition at baseline. Repeated measures analyses were used to investigate changes in cognition from baseline to follow-up. Results: On average, participants were 68.6 years of age (SD = 5.9) with 16.1 years of education (SD = 4.7). Age, income, and education showed robust associations with baseline cognition. Subjective cognitive impairment was associated with lower performance in global cognition, verbal learning, and memory domains. Only performance in the attention domain decreased at follow-up, and subjective health state and depressive symptoms significantly predicted the change in attention. Discussion: Our study findings contribute to the investigation of cognitive health in older Hispanic women and to the understanding of sociodemographic and health-related factors associated with cognitive decline and the progression to cognitive impairment and dementia.

Assessing the reproducibility and predictive value of objective cough measurement for successful withdrawal of invasive ventilatory support in adult patients.

BACKGROUND: Utilizing clinical tests, such as objective cough measurement, can assist in predicting the success of the weaning process in critically ill patients. METHODS: A multicenter observational analytical study was conducted within a prospective cohort of patients recruited to participate in COBRE-US. We assessed the capability of objective cough measurement to predict the success of the spontaneous breathing trial (SBT) and extubation. Intra- and inter-observer reproducibility of the cough test and was evaluated using the intraclass correlation coefficient (ICC) and Cohen's weighted kappa. We used receiver operating characteristic curves (ROC-curve) to evaluate the predictive ability of objective cough measurement. RESULTS: We recruited 367 subjects who were receiving invasive mechanical ventilation. A total of 451 objective cough measurements and 456 SBTs were conducted. A significant association was found between objective cough measurement and successful SBT (OR: 1.68; 95% CI 1.48-1.90; p = 0.001). The predictive capability of the objective cough test for SBT success had a ROC-curve of 0.58 (95% CI: 0.56-0.61). Objective cough measurement to predict successful extubation had a ROC-curve of 0.61 (95% CI: 0.56-0.66). The intraobserver reproducibility exhibited an ICC of 0.94 (95% CI: 0.89-0.96; p < 0.001), while the interobserver reproducibility demonstrated an ICC of 0.72 (95% CI: 0.51-0.85; p < 0.001). The intraobserver agreement, assessed using Cohen's weighted kappa was 0.94 (95% CI: 0.93-0.99; p < 0.001), whereas the interobserver agreement was 0.84 (95% CI: 0.67 - 0.10; p < 0.001). CONCLUSIONS: The objective measurement of cough using the method employed in our study demonstrates nearly perfect intra-observer reproducibility and agreement. However, its ability to predict success or failure in the weaning process is limited.

Effects of a WhatsApp-Assisted Health Educational Intervention for Cardiac Rehabilitation: A Randomized Controlled Clinical Trial Protocol.

Although the effectiveness of cardiac rehabilitation (CR) programs in secondary prevention is well-recognized, there is a lack of studies exploring the potential of mobile health to enhance educational interventions within CR. The objective is to assess the impact of a structured WhatsApp-assisted health educational intervention, in conjunction with the usual care, compared to the usual care alone among participants enrolled in a CR program. The trial will recruit 32 participants enrolled in a CR program, who will be randomly assigned to a structured WhatsApp-assisted health educational intervention plus usual care or usual care alone group. The intervention will span 4 weeks, with assessments at baseline, 4 weeks, and 3, 6, and 12 months. The primary outcome measure is the cardiovascular risk factors knowledge score. Secondary outcomes include physical activity levels, anxiety and depression, and quality of life. Expected results include improved knowledge of cardiovascular risk factors, increased physical activity levels, and better mental health outcomes in the intervention group. Additionally, an enhancement in the overall quality of life is anticipated. These findings are expected to underscore the value of integrating mHealth with traditional CR methods, potentially shaping future approaches in chronic disease management and prevention.

Microstructural and physicochemical quality maintenance in green bell pepper infected with Botrytis cinerea and treated with thyme essential oil combined with carnauba wax.

Bell pepper presents rapid weight loss and is highly susceptible to gray mold caused by the fungus Botrytis cinerea. The most employed method to control this disease is the application of synthetic fungicides such as thiabendazole (TBZ); however, its continued use causes resistance in fungi as well as environmental problems. For these reasons, natural alternatives arise as a more striking option. Currently, bell pepper fruits are coated with carnauba wax (CW) to prevent weight loss and improve appearance. Moreover, CW can be used as a carrier to incorporate essential oils, and previous studies have shown that thyme essential oil (TEO) is highly effective against B. cinerea. Therefore, this study aimed to evaluate the effect of CW combined with TEO on the development of gray mold and maintenance of microestructural and postharvest quality in bell pepper stored at 13°C. The minimal inhibitory concentration of TEO was 0.5%. TEO and TBZ provoked the leakage of intracellular components. TEO and CW + TEO treatments were equally effective to inhibit the development of gray mold. On the quality parameters, firmness and weight loss were ameliorated with CW and CW + TEO treatments; whereas lightness increased in these treatments. The structural analysis showed that CW + TEO treatment maintained the cell structure reducing the apparition of deformities. The results suggest that CW + TEO treatment could be used as a natural and effective antifungal retarding the appearance of gray mold and maintaining the postharvest quality of bell pepper. PRACTICAL APPLICATION: CW and TEO are classified as generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA). This combination can be employed on the bell pepper packaging system to extend shelf life and oppose gray mold developments. Bell pepper fruits are normally coated with lipid-base coatings such as CW before commercialization; therefore, TEO addition would represent a small investment without any changes on the packaging system infrastructure.

Wearable Biosensor Technology in Education: A Systematic Review.

Wearable Biosensor Technology (WBT) has emerged as a transformative tool in the educational system over the past decade. This systematic review encompasses a comprehensive analysis of WBT utilization in educational settings over a 10-year span (2012-2022), highlighting the evolution of this field to address challenges in education by integrating technology to solve specific educational challenges, such as enhancing student engagement, monitoring stress and cognitive load, improving learning experiences, and providing real-time feedback for both students and educators. By exploring these aspects, this review sheds light on the potential implications of WBT on the future of learning. A rigorous and systematic search of major academic databases, including Google Scholar and Scopus, was conducted in accordance with the PRISMA guidelines. Relevant studies were selected based on predefined inclusion and exclusion criteria. The articles selected were assessed for methodological quality and bias using established tools. The process of data extraction and synthesis followed a structured framework. Key findings include the shift from theoretical exploration to practical implementation, with EEG being the predominant measurement, aiming to explore mental states, physiological constructs, and teaching effectiveness. Wearable biosensors are significantly impacting the educational field, serving as an important resource for educators and a tool for students. Their application has the potential to transform and optimize academic practices through sensors that capture biometric data, enabling the implementation of metrics and models to understand the development and performance of students and professors in an academic environment, as well as to gain insights into the learning process.

Physicochemical characterization of the pod husk of Theobroma cacao L. of clones CCN51, FEAR5, and FSV41 and its agroindustrial application.

In cocoa production, the harvest and postharvest processes tend to generate residues that, if not properly treated or disposed of, become a source of pests or diseases for the crop and the farmer. The residues are environmental contaminants, which are equivalent to 70%-80% of the total fruit (husk, placenta, leachates). In the case of cacao pod husk (CPH), it is hollow form contributes to the accumulation of water or leachates. These residues with no apparent profitable use may have components of agroindustrial interest, such as pectins, cellulose, and starches, in products with high added value. Thus, the physicochemical characterization CPH of clones Castro Naranjal Collection 51 (CCN51), FEDECACAO Arauquita 5 (FEAR5), and FEDECACAO San Vicente 41 (FSV41) is presented to identify different applications such as biopolymers, bioremediation, and renewable energies and their potential biotechnological use in contributing to the circular economy according to the characteristics of each clone. In conclusion, it is important to continue with the research on CPHs of the different clones and to promote the sustainable development of cocoa in the Department of Risaralda, Colombia.

Surfactant therapy using vibrating-mesh nebulizers in adults with COVID-19-induced ARDS: A case series.

Coronavirus adult respiratory distress syndrome, characterized by decreased surfactant due to lysis of type II pneumocytes and hyaline membrane formation, contributes to severe hypoxemia. The administration of surfactant via high-flow nasal cannula (HFNC) may positively affect lung structure and function in this context. In this study, we report on five clinical cases, encompassing patients aged 40-60 years of both sexes, who tested positive for coronavirus disease 2019 via real-time polymerase chain reaction and exhibited significant pulmonary compromise with elevated inflammatory biomarkers. These patients were treated with aerosol therapy using surfactant delivered through vibrating-mesh nebulizers alongside HFNC. Of these patients, four demonstrated positive responses to the treatment, suggesting that aerosol therapy with surfactant through vibrating-mesh nebulizers could be a viable rescue therapy in adults receiving HFNC oxygen therapy for hypoxemic respiratory failure caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Unfortunately, one patient had a negative outcome and succumbed. The findings from these cases indicate that the use of aerosol therapy with vibrating-mesh nebulizers as rescue therapy might offer an alternative approach for managing adults with hypoxemic respiratory failure due to SARS-CoV-2, as evidenced by the positive outcomes in four out of the five cases presented.

Young Plasma Rejuvenates Blood DNA Methylation Profile, Extends Mean Lifespan, and Improves Physical Appearance in Old Rats.

There is converging evidence that young blood conveys cells, vesicles, and molecules able to revitalize function and restore organ integrity in old individuals. We assessed the effects of young plasma on the lifespan, epigenetic age, and healthspan of old female rats. Beginning at 25.6 months of age, a group of 9 rats (group T) was intraperitoneally injected with plasma from young rats until their natural death. A group of 8 control rats of the same age received no treatment (group C). Blood samples were collected every other week. Survival curves showed that from age 26 to 30 months, none of the group T animals died, whereas the survival curve of group C rats began to decline at age 26 months. Blood DNAm age versus chronological age showed that DNAm age in young animals increased faster than chronological age, then slowed down, entering a plateau after 27 months. The DNAm age of the treated rats fell below the DNAm age of controls and, in numerical terms, remained consistently lower until natural death. When rats were grouped according to the similarities in their differential blood DNA methylation profile, samples from the treated and control rats clustered in separate groups. Analysis of promoter differential methylation in genes involved in systemic regulatory activities revealed specific GO term enrichment related to the insulin-like factors pathways as well as to cytokines and chemokines associated with immune and homeostatic functions. We conclude that young plasma therapy may constitute a natural, noninvasive intervention for epigenetic rejuvenation and health enhancement.

Polypharmacy and Associated Health Outcomes in the PARI-HD Study.

Background: A growing body of evidence points to potential risks associated with polypharmacy (using ≥5 medications) in older adults, but most evidence is derived from studies where racial and ethnic minorities remain underrepresented among research participants. Objective: Investigate the association between polypharmacy and cognitive function, subjective health state, frailty, and falls in Hispanic older adults. Methods: Panama Aging Research Initiative-Health Disparities (PARI-HD) is a community-based cohort study of older adults free of dementia at baseline. Cognitive function was measured with a neuropsychological test battery. Frailty assessment was based on the Fried criteria. Subjective health state and falls were self-reported. Linear and multinomial logistic regression analyses were used to examine association. Results: Baseline evaluations of 468 individuals with a mean age of 69.9 years (SD = 6.8) were included. The median number of medications was 2 (IQR: 1-4); the rate of polypharmacy was 19.7% (95% confidence interval [CI] = 16.1-23.3). Polypharmacy was inversely associated with self-rated overall health (b =-5.89, p < 0.01). Polypharmacy users had 2.3 times higher odds of reporting two or more falls in the previous 12 months (odds ratio [OR] = 2.31, 95% CI = 1.06-5.04). Polypharmacy was independently associated with Fried's criteria for pre-frailty (OR = 2.90, 95% CI = 1.36-5.96) and frailty (OR = 5.14, 95% CI = 1.83-14.42). Polypharmacy was not associated with cognitive impairment. Conclusions: These findings illustrate the potential risks associated with polypharmacy among older adults in Panama and may inform interventions to improve health outcomes in this population.

Competencies of the nurses in the limitation of therapeutic effort in the intensive care unit: An integrative review.

Objective: Nurses inevitably encounter patients who require care aimed at limiting therapeutic effort (LTE), even though many of them are not prepared to provide support to individuals with terminal illnesses and their families. One of the contexts in which the LTE is considered is the intensive care unit (ICU). This review is to describe the competencies for the execution of a nursing professional role in the LTE in the ICU. Method: An integrative review of the literature published between the years 2010 and 2023. The search was carried out in five databases: Medline, Wiley Online Library, SciELO, ScienceDirect, and Web of Science. The Critical Appraisal Skills Programme in Spanish was used as the template for study evaluation. The methodology of the Oxford Center for Evidence-Based Medicine (CEBM) was used to assess the level of evidence and the degree of recommendation. Result: A total of 25 articles in a wide range of studies were included. The findings suggest that the competencies for LTE in the ICU are direct patient care, family-centered care, and the role of the nurse within the team. However, more high-quality studies are needed to confirm these conclusions. Three categories were identified: (a) competencies as defender agent between the patient, his family, and the interdisciplinary team; (b) competencies for decision-making in limiting the therapeutic effort; and (c) competencies for nursing therapeutic interventions at the end of life. Conclusion: The competencies of the nursing professionals who work in the adult ICU in the LTE are essential to the patient's quality of life, dignity of their death, and comprehensive family support for coping with grief.

Exploration adhesion properties of Liquorilactobacillus and Lentilactobacillus isolated from two different sources of tepache kefir grains.

Due to the distinctive characteristics of probiotics, it is essential to pinpoint strains originating from diverse sources that prove efficacious in addressing a range of pathologies linked to dysfunction of the intestinal barrier. Nine strains of lactic acid bacteria were isolated from two different sources of tepache kefir grains (KAS2, KAS3, KAS4, KAS7, KAL4, KBS2, KBS3, KBL1 and KBL3), and were categorized to the genus Lacticaseibacillus, Liquorilactobacillus, and Lentilactobacillus by 16S rRNA gene. Kinetic behaviors of these strains were evaluated in MRS medium, and their probiotic potential was performed: resistance to low pH, tolerance to pepsin, pancreatin, bile salts, antibiotic resistance, hemolytic activity, and adhesion ability. KAS7 strain presented a higher growth rate (0.50 h-1) compared with KAS2 strain, who presented a lower growth rate (0.29 h-1). KBS2 strain was the only strain that survived the in vitro stomach simulation conditions (29.3%). Strain KBL1 demonstrated significantly higher viability (90.6%) in the in vitro intestine simulation conditions. Strain KAS2 demonstrated strong hydrophilic character with chloroform (85.6%) and xylol (57.6%) and a higher percentage of mucin adhesion (87.1%). However, strains KBS2 (84.8%) and KBL3 (89.5%) showed the highest autoaggregation values. In terms of adhesion to the intestinal epithelium in rats, strains KAS2, KAS3 and KAS4 showed values above 80%. The growth of the strains KAS2, KAS3, KAS4, KBS2, and KBL3 was inhibited by cefuroxime, cefotaxime, tetracycline, ampicillin, erythromycin, and cephalothin. Strains KBS2 (41.9% and 33.5%) and KBL3 (42.5% and 32.8%) had the highest co-aggregation values with S. aureus and E. coli. The results obtained in this study indicate that lactic acid bacteria isolated from tepache can be considered as candidates for potentially probiotic bacteria, laying the foundations to evaluate their probiotic functionality in vivo and thus to be used in the formulation of functional foods.

Curricular and pedagogical approaches for physical activity prescription training: a mixed-methods study of the "Exercise is Medicine" workshops in Colombia.

BACKGROUND: The physical activity (PA) prescription workshop for physicians, through the global health initiative "Exercise is Medicine" (EIM), has trained more than 4000 health care professionals (HCPs) in Latin America. It has shown to be effective in increasing PA prescription knowledge and awareness among HCPs. The purpose of this paper is to evaluate the curricular and pedagogical approach used by EIM Colombia at the PA prescription workshops implemented between 2014 and 2015. METHODS: A mixed methods study, with a sequential explanatory design was implemented among a convenience sample of HCPs attending twenty-six PA prescription workshops. HCPs health status, PA personal habits, and medical practices were collected using a questionnaire at baseline among 795 participants (pre-test measurement), and subsequently quantitatively analyzed. A workshop satisfaction survey was administered after the completion of the workshop among 602 HCPs. The curricular and pedagogical approach of the workshop, the designers' and students' contextual factors, and perceptions about the workshop were measured using qualitative methods (analysis of the procedures manual, two workshop observations, three semi-structured interviews, and one focus group including 8 HCPs). RESULTS: The workshop is student-centered and guided by an expert with an academic and clinical background. Learning was achieved with theoretical and practical components using authentic performance and collaborative learning. An active teaching and learning approach was used with strategies such as interactive lectures, hands-on elements, and role-playing (patient-counselor). The workshop emphasized an individual approach when prescribing PA integrating in clinical practice not only health benefits but also patient´s beliefs, motivations, needs, and barriers. CONCLUSIONS: Evidence-based practices and authentic performance were the most salient pedagogical elements used by EIM Colombia at the PA prescription workshop. A knowledge assessment that includes the practical aspect is suggested for future workshops. The curricular and pedagogical approach of the PA prescription workshop implemented in Colombia is well received by the medical community and a useful continuing medical education intervention with a potential contribution to current, and future health promotion needs.

Health-related fitness in medical students: a curricular intervention in Bogota, Colombia.

OBJECTIVE: To evaluate the impact of a curricular intervention to promote health-related fitness (HRF) among medical students in Bogota, Colombia. METHOD: The study was conducted between May 2014 and December 2015 as part of the medical physiology course, in which 208 medical students were enrolled.The curricular intervention included two lectures on physical activity (PA) and student-led group presentations on the physiological effects of exercise on human physiology. An academic incentive (10% of final grade) was given to students who reported and documented regular PA practice during the semester. This study assessed students' HRF variables, perceptions of the curriculum intervention, and PA practices using quantitative and qualitative approaches. RESULTS: 55% of the students were female, with a mean age of 19.5 years. Body fat, estimated maximum oxygen consumption (VO2max), handgrip, and sit-up strength showed statistically significant improvements at the end of the intervention. Students reported that PA practice was positively influenced by the curriculum intervention, particularly the academic incentive and the HRF tests. Students reported a wide variety of PA practices, which were mainly done with friends, classmates, or family members. Lack of time was the main reported barrier to PA practice. CONCLUSION: The curricular intervention was effective in improving HRF and promoting PA. It remains to be investigated whether these gains are sustained over time.

Características en resonancia magnética de la degeneración de leiomiomas / Characteristics in magnetic resonance of the degeneration of leiomyomas

Resumen La neoplasia ginecológica más frecuente son los leiomiomas uterinos, tumores benignos hormonodependientes que se generan del músculo liso del miometrio. Presentan una alta incidencia en mujeres en edad reproductiva entre la cuarta y quinta década de la vida y suelen disminuir con la menopausia. Generalmente son asintomáticos, pero a menudo se pueden acompañar de dismenorrea, metrorragia o infertilidad. El estudio inicial para su caracterización es la ecografía transvaginal; sin embargo, la resonancia magnética tiene un alto valor diagnóstico, ya que permite una evaluación más específica sobre el tipo, ubicación y número de leiomiomas, así como también permite identificar el tipo de degeneración y diferenciar entre leiomiomas y sus lesiones imitadoras. El objetivo principal de este manuscrito es abordar las principales características en resonancia magnética entre los distintos tipos de degeneración leiomiomatosa, siendo esta una causa de posible dolor abdominal y pélvico agudo.

Abstract The most common gynecological neoplasm is uterine leiomyomas, these are benign hormone-dependent tumors that are generated from the smooth muscle of the myometrium. They have a high incidence in women of reproductive age between the fourth and fifth decades of life and usually decrease with menopause. They are generally asymptomatic, but can often be accompanied by dysmenorrhea, metrorrhagia, or infertility. The initial study for its characterization is transvaginal ultrasound, however, magnetic resonance imaging has a high diagnostic value since it allows a more specific evaluation of the type, location and number of leiomyomas, as well as allowing the identification of the type of degeneration and differentiation. between leiomyomas and their mimic lesions. The main objective of this manuscript is to address the main characteristics in magnetic resonance between the different types of leiomyomatous degeneration, this being a cause of possible acute abdominal and pelvic pain.

Experiencias en lactancia materna, vivencia desde la mujer que amamanta: estudio cualitativo / Breastfeeding experiences from the perspective of the breastfeeding woman: qualitative study

Objetivos: Comprender las experiencias sobre la lactancia materna desde la perspectiva de las mujeres, en un grupo de madres lactantes primerizas. Materiales y métodos: Estudio cualitativo, bajo la perspectiva de etnografía, enfocado en un grupo de mujeres de la región oriente del departamento de Antioquia (Colombia). Por muestreo intencional y hasta la saturación de los datos se seleccionaron 16 mujeres lactantes primerizas, de 18 años o más, con hijos menores de 24 meses y que se encontraran amantando o hubiesen amantado de forma exclusiva al menos durante tres meses. Se realizaron entrevistas semiestructuradas y observación participante; el análisis de los datos se desarrolló por triangulación y codificación abierta y axial. Los resultados se presentan a través de la descripción de categorías. Resultados: Se identificaron cuatro categorías frente a la experiencia del amamantamiento: el agotamiento y el dolor que se disipan con amor, la lactancia y el nuevo orden de las cosas, las emociones de una mujer en el cuerpo de una madre y la lactancia: un acto social. Conclusiones: Proteger la lactancia materna requiere poner especial cuidado a la mujer como sujeto, más allá del amamantamiento, dando prioridad a su salud física y emocional como elementos esenciales que deben ser considerados por los profesionales en salud. Se requieren estudios que evalúen los efectos de la creación de grupos de apoyo que propicien el intercambio de saberes para acompañar a la mujer lactante

Objectives: To understand the breastfeeding experience from the perspective of a group of women who breastfeed for the first time. Material and methods: Qualitative study from an ethnographic perspective, focusing on a group of women from the eastern region of the Department of Antioquia (Colombia). Intentional sampling until data saturation was used. The group included 16 first-time breastfeeding mothers aged 18 or older, with children under 24 months of age and who were breastfeeding or had breastfed exclusively for at least three months. Semi-structured interviews and participant observations were carried out. Data were analyzed by triangulation and open and axial coding. The results are presented in the form of category descriptions. Results: Four categories were identified in relation to the breastfeeding experience: exhaustion and pain dispelled by love, breastfeeding and the new order of things, emotions of a woman embodied in a mother, and breastfeeding as a social act. Conclusions: Protection of breastfeeding requires special attention to the woman as a subject beyond the act of breastfeeding, giving priority to her physical and emotional health as essential elements that must be kept in mind by healthcare professionals. Studies to assess the effects of creating support groups that foster the exchange of insights to help the breastfeeding woman are required.

New daily persistent headache after SARS-CoV-2 infection in Latin America: a cross-sectional study.

BACKGROUND: Persistent headache is a frequent symptom after coronavirus disease 2019 (COVID-19) and there is currently limited knowledge about its clinical spectrum and predisposing factors. A subset of patients may be experiencing new daily persistent headache (NDPH) after COVID-19, which is among the most treatment-refractory primary headache syndromes. METHODS: We conducted a cross-sectional study in Latin America to characterize individuals with persistent headache after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and to identify factors associated with NDPH. Participants over 18 years old who tested positive for SARS-CoV-2 infection and reported persistent headache among their symptoms completed an online survey that included demographics, past medical history, persistent headache clinical characteristics, and COVID-19 vaccination status. Based on participants' responses, NDPH diagnostic criteria were used to group participants into NDPH and non-NDPH groups. Participant data was summarized by descriptive statistics. Student's t and Mann-Whitney U tests were used according to the distribution of quantitative variables. For categorical variables, Pearson's chi-square and Fisher's exact tests were used according to the size of expected frequencies. Binomial logistic regression using the backward stepwise selection method was performed to identify factors associated with NDPH. RESULTS: Four hundred and twenty-one participants from 11 Latin American countries met the inclusion criteria. One in four participants met the NDPH diagnostic criteria. The mean age was 40 years, with most participants being female (82%). Over 90% of the participants reported having had mild/moderate COVID-19. Most participants had a history of headache before developing COVID-19 (58%), mainly migraine type (32%). The most predominant clinical characteristics in the NDPH group were occipital location, severe/unbearable intensity, burning character, and radiating pain (p < 0.05). A higher proportion of anxiety symptoms, sleep problems, myalgia, mental fog, paresthesia, nausea, sweating of the face or forehead, and ageusia or hypogeusia as concomitant symptoms were reported in participants with NDPH (p < 0.05). Palpebral edema as a concomitant symptom during the acute phase of COVID-19, occipital location, and burning character of the headache were risk factors associated with NDPH. CONCLUSION: This is the first study in Latin America that explored the clinical spectrum of NDPH after SARS-CoV-2 infection and its associated factors. Clinical evaluation of COVID-19 patients presenting with persistent headache should take into consideration NDPH.

Resilience mediates the effect of the COVID-19 pandemic on mental health in a sample of adults in Panama.

Background: The COVID-19 pandemic was characterized by global increases in depression, anxiety, and stress symptoms. Previous studies have shown that resilience mitigates these symptoms, however there is limited research exploring the link between resilience and mental illness during the COVID-19 pandemic in Central America. Objective: To examine the role of resilience as it relates to the perceived effect of the pandemic on mental health symptoms. Methods: A sample of 480 adults in Panama were recruited from March to May 2021 to complete an online survey. The online survey consisted of sociodemographic questions and scale measures assessing depression, anxiety and stress symptoms, resilience, and social support. Results: Results indicated that resilience mediated the relationship between the perceived effect of the COVID-19 pandemic and mental health symptoms; participants who felt more personally affected by the pandemic reported more depression, anxiety, and stress symptoms via decreased resilience. Further analyses revealed that resilience was moderated by sex and social support, showing that the indirect effect of resilience was greater for women and individuals who perceived low social support. Discussion: These findings contribute to a growing body of research documenting the adverse effects of the COVID-19 pandemic on mental health and reveal potential mechanisms through which pandemic-related distress decreases resilience, thereby increasing symptoms of mental illness.

Epidemiology of Invasive Meningococcal Disease in Colombia: A Retrospective Surveillance Database Analysis.

INTRODUCTION: Invasive meningococcal disease (IMD), caused by Neisseria meningitidis, is associated with high morbidity and mortality. The aim of the current study was to describe the historical and recent epidemiology of IMD in Colombia. METHODS: This retrospective surveillance database analysis examined all available data on IMD in Colombia. Data were extracted from publicly available disease event reports and laboratory surveillance reports or obtained directly from hospitals in Cartagena. RESULTS: During 2015-2021, the overall incidence of IMD was 0.04-0.18 per 100,000 based on laboratory surveillance reports. IMD incidence was highest among infants aged < 1 year (0.52-1.47 per 100,000), as was IMD mortality (0.00-0.65 per 100,000). Serogroup B was the dominant serogroup responsible for IMD in Colombia during 1988-2014, but, since 2015, serogroup C has been dominant in all age groups, followed by serogroups B and Y. During 2010-2021 combined, the majority of IMD cases were reported in Bogotá (31.9%) and Antioquia (21.7%). Of 42 IMD cases in the city of Cartagena, 54.8% occurred in people who lived in the poorest neighborhoods, and these patients had the highest IMD lethality (52.2%) and the shortest median hospitalization duration (3 days). CONCLUSION: The overall incidence of IMD in Colombia was low but was highest among infants aged < 1 year. IMD cases tended to be concentrated in the more densely populated areas and in poorer neighborhoods. As the majority of IMD cases in Colombia since 2015 have been serogroup C, followed by B or Y, vaccination to protect against these serogroups could potentially be beneficial and help to achieve the World Health Organization's and Pan American Health Organization's roadmaps to defeat meningitis by 2030.

Air Pollution and Cardiac Diseases: A Review of Experimental Studies.

Air pollution is associated with around 6.5 million premature deaths annually, which are directly related to cardiovascular diseases, and the most dangerous atmospheric pollutants to health are as follows: NO2, SO2, CO, and PM. The mechanisms underlying the observed effects have not yet been clearly defined. This work aims to conduct a narrative review of experimental studies to provide a more comprehensive and multiperspective assessment of how the effect of atmospheric pollutants on cardiac activity can result in the development of cardiac diseases. For this purpose, a review was carried out in databases of experimental studies, excluding clinical trials, and epidemiological and simulation studies. After analyzing the available information, the existence of pathophysiological effects of the different pollutants on cardiac activity from exposure during both short-term and long-term is evident. This narrative review based on experimental studies is a basis for the development of recommendations for public health.
