Consecuencias de los conflictos armados en la salud mental de niños y adolescentes: revisión de revisiones de la literatura

Introduction:

Armed conflicts affect the mental health of children and adolescents. Their outcomes in these populations have been documented identifying vulnerability and significant biopsychosocial damage as the most common factors.

Objective:

To identify and synthesize the mental health consequences of armed conflicts in children and adolescents.

Materials and methods:

We carried out a comprehensive and systematic search of reviews published until July 2019 in the MEDLINE (Ovid), EMBASE, Cochrane Central Register of Controlled Trials, and LILACS databases, as well as in additional sources. The information was retrieved and analyzed narratively by describing the characteristics and objectives of the studies and the mental health consequences of armed conflicts in three periods of time: pre-armed conflict, during the armed conflict, and post-conflict.

Results.

Out of 587 potentially relevant studies, we finally selected 72. In the pre-armed conflict period, we described in detail the psychological experiences and the anticipatory somatic symptoms. During the conflict, we identified regressive, behavioral, and cognitive symptoms such as enuresis, fear, sadness, aggression, hyperactivity, and inattention, among others. Direct mental health consequences such as adjustment disorders, depression, anxiety, and post-traumatic stress were also identified. Finally, in the post-conflict period, we referred to the transmission of mental health consequences and resilience processes. On the other hand, we reviewed in depth the potential consequences of armed conflicts on biopsychosocial development, morality, identity, culture, education, and society.

Conclusion.

The development of mental health consequences due to the exposure to armed conflicts in these populations is a complex process that depends on the stage of the exposure, the length of the conflict, and contextual factors.     

Evaluación de la efectividad de la prueba rápida OptiMAL-IT™ para el seguimiento de pacientes con diagnóstico de malaria en la Amazonía peruana

Introduction:

In Peru, optical microscopy with the thick smear test continues to be performed for the follow-up of malaria patients. This test is simple but it requires microscopic equipment and suitable staff to perform the reading of the samples. Studies suggest that the rapid OptiMAL-IT™ test is an option for follow-up.

Objective:

To evaluate the effectiveness of OptiMAL-IT™ as a follow-up test in malaria patients in endemic areas of Perú.

Materials and methods:

We conducted an observational, analytical cross-sectional study of diagnostic tests performed in patients with malaria. We selected all the patients attending different health facilities in the Peruvian departments of San Martín and Loreto who met the inclusion criteria. Optical microscopy with thick smear and OptiMAL-IT™ was used on days 2, 3, 7, and 14 for Plasmodium vivax and until day 21 of follow-up for Plasmodium falciparum. Percentages of correctly classified samples and predictive values were calculated, and the results were compared between the western jungle and the eastern jungle using Chi2 or Fisher''s exact tests.

Results:

We registered 262 patients from San Martín and 302 from Loreto. The percentage of correctly classified cases and the negative predictive value were higher than 92.0% and 93,0%, respectively, from the third day of follow-up; no statistical differences were found in the results obtained from the western jungle and those from the eastern jungle.

Conclusions:

The OptiMAL-IT™ test would be effective as a follow-up test in patients diagnosed with malaria in endemic areas of Perú.     

Evaluación de las características operativas de la versión 2.2018 del instrumento de evaluación del malestar emocional de la National Comprehensive Cancer Network en pacientes atendidos en el Instituto Nacional de Cancerología,Bogotá

Introduction:

Cancer patients have significant levels of emotional distress. The National Comprehensive Cancer Network (NCCN) developed the distress management tool to quickly assess significant distress in oncological patients who require intervention. For its use in Colombia, we made its cross-cultural adaptation and validation.

Objective:

To determine the operative characteristics of the distress management tool, version 2.2018, in patients seen at the Instituto Nacional de Cancerología (INC) in Colombia.

Materials and methods:

Counting with the authorization from the NCCN, we translated, made the cross-cultural adaptation, and evaluated the operational characteristics of the tool. We included 343 cancer patients seen at the INC, who filled out the cross-culturally adapted instrument. A diagnostic test study was carried out with a semi-structured interview as a reference.

Results:

The patients had an average age of 49.7 years (SD=15) and the majority were women (67%). The instrument had an area under the ROC curve of 0.81 (95% CI: 0.77 - 0.86); its optimal cut-off point was 3.5 approached to 4 when using integers on the scale; its sensitivity was 0.81 (95% CI: 0.76 - 0.85), and its specificity, 0.69 (95% CI: 0.64 - 0.74). The agreement percentage between the result of the interview and the instrument was 73% (kappa = 0.64; p< 0.001).

Conclusions:

The distress management tool allowed for the detection of moderate to severe distress requiring intervention and management. This instrument was adapted and validated in cancer patients in Colombia keeping the cutoff point at ≥ 4 as in the original version.     

Análisis del impacto presupuestal en Colombia de la prueba de HPV con genotipificación comparada con la citología

Introduction:

The detection of the human papillomavirus (HPV) through the combination of the HPV test and other techniques such as cytology has impacted the detection and timely treatment of lesions associated with cervical cancer.

Objective:

To estimate the budgetary impact of the strategy of early detection of HPV with DNA test genotyping with reflex cytology versus conventional cytology in women aged 30 to 65 years attending the cervical cancer screening program at a health benefit managing entity in Colombia.

Materials and methods:

Using a decision tree and a Markov model, the clinical implications and direct costs of screening, diagnosis, and treatment were estimated in a cohort of women. The analysis considered two screening cycles and their annual costs. The data on the prevalence of clinical results and the costs were taken from the health managing entity. The information on the progression, persistence, and regression of the health states were taken from the ATHENA study.

Results:

The screening scheme with the HPV test, genotyping, and reflex cytology compared to conventional cytology was cost-saving. The average cost per screening cycle with the HPV test was estimated at COP $ 129,201,363 and with cytology at COP $ 186,309,952, i.e., a saving of COP $ 57,108,589 (30.7%).

Conclusion:

The implementation of the screening strategy under evaluation suggests prospective savings derived from the early detection of health states associated with the development of cervical cancer.     

Malaria importada en población pediátrica de Alicante,España (1994-2019)

Introduction:

In recent years there has been an increase in imported malaria among children in whom it is a potentially serious and fatal disease.

Objective:

To describe the incidence and the clinical and epidemiological characteristics of malaria in children diagnosed in Alicante, Spain, over a 26-year period.

Materials and methods:

We conducted an observational retrospective study of malaria in children aged under 15 years diagnosed at the Alicante General University Hospital from 1994 to 2019.

Results:

Twenty-four cases were registered over the study period. The frequency of cases increased from 2 over the first five years to 11 in the last five years. The median age of the children was 6 years (interquartile range: 3-8); 91.6% came from sub-Saharan Africa. Over half (n=15, 62.5%) were children born in Spain to immigrant parents visiting friends and relatives (VFR); just one (6.7%) had received antimalarial chemoprophylaxis.The most frequent clinical signs were fever (86.9%), hepatosplenomegaly (70.8%), and anemia (70.8%). Plasmodium falciparum was the most frequently identified species (83.3%, n=20). The most common treatment was oral piperaquine/dihydroartemisinin (41.6%, n=10) with favorable outcomes in all cases.

Conclusions:

Imported childhood malaria shows an increasing incidence and a nonspecific clinical presentation. Professional awareness of this disease and a high degree of clinical suspicion are needed for the early initiation of treatment. Pre-travel preventive measures should be promoted when appropriate.     

Aspectos biomédicos y epidemiológicos del accidente ofídico en el departamento del Cauca,Colombia, 2009-2018

Introduction:

Snakebite is a relevant public health problem in Colombia, which is evident in epidemiological data at the Latin American level, where it ranks third place in the number of snakebites, after México and Brazil.

Objective:

To perform a retrospective analysis of snakebite accidents in the department of Cauca between 2009 and 2018 based on the data from the Public Health Surveillance System of Colombia reported to the Health Institute of Cauca.

Materials and methods:

We compiled and interpreted the information from the compulsory snakebite notification forms for the study’s 10 years period. We determined snakebite incidence and frequency according to the geographical distribution and the causal agents, and we analyzed related socioeconomic variables as well.

Results:

The records accounted for 1,653 cases and low mortality. Bothrops and Bothriechis species (77.43%) caused most of the accidents followed by Micrurus (2.9%). Most of the notifications came from the south of the department, and males and farmers were the most affected with bites mainly in the upper extremities. During poisoning, hemorrhagic manifestations predominated over necrosis and infections; serotherapy criteria were not always adequately applied, however, iatrogenic complications were not frequent.

Conclusions:

El Tambo and Piamonte municipalities, being male, and rural areas were the variables most affected by ophidism, mainly bothropic ophidism. The highest incidences occurred in the southern part of Cauca, in the Patía and Caquetá river basins.     

Expresión de los componentes del inflamasoma y su relación con los marcadores de riesgo cardiovascular en personas con infección por HIV-1

Introduction:

HIV-1 infection induces a chronic inflammatory state in which inflammasomes participate. The increase in inflammatory parameters is higher in individuals with active viral replication (progressors) than in those with viral control (HIV-1 controllers). This process triggers metabolic alterations related to changes in the lipid profile, which could increase the risk of cardiovascular events, even in patients with antiretroviral therapy.

Objective:

To establish whether there was a correlation between the expression of inflammasome components and cardiovascular risk markers in HIV-1 controllers and progressors with or without antiretroviral therapy.

Materials and methods:

We studied 13 HIV-1 controllers and 40 progressors (19 without antiretroviral therapy and 31 with therapy) and evaluated in them classic markers of cardiovascular risk. Using RT-PCR we quantified the expression of inflammasome components (NLRP1, NLRP3, NLRC4, AIM2, ASC, IL-1β, IL-18, and caspase-1), TLR2, TLR4, TGF-β, and IL-10.

Results:

Progressors with antiretroviral therapy had an increased expression of TLR2, TLR4, and IL-18 compared to HIV-1 controllers. They also showed high levels of triglycerides and VLDL, which positively correlated with the expression of the inflammasome components NLRP1, NLRP3, NLRC4, AIM2, ASC, and caspase-1.

Conclusion:

Progressors receiving antiretroviral therapy exhibited an increased expression of the inflammasome components, which correlated with the levels of triglycerides and VLDL. This supports the role of inflammation in cardiovascular risk during HIV-1 infection.     

Importancia de la determinación de variantes en el número de copias en neonatos con aneuploidías autosómicas

Introduction:

Aneuploidies are frequent genetic disorders in clinical practice. However, little is known about other genetic variants that may influence the final phenotype.

Objective:

To determine the variations in the number of copies and regions with homozygosity greater than 0.5% or larger than 10 Mb in newborns with autosomal aneuploidies.

Materials and methods:

We performed a chromosomal microarray analysis on newborns with autosomal aneuploidies (n=7), trisomy 21 (n=5), and trisomy 18 (n=2) evaluated at the Hospital Antonio Lorena and Hospital Regional of Cusco, Perú, during 2018.

Results:

We found pathogenic and probably pathogenic variants in the number of copies in other genomic regions different to chromosomes 21 or 18 in two neonates. Additionally, we found two variants bigger than 500 kpb of unknown pathogenicity.

Conclusions:

Although the number of analyzed individuals was small, it is important to highlight that we found other variants in the number of copies that have been described in association with neurodevelopmental disorders, congenital anomalies, deafness, and short/ tall stature, among others, in almost half of them, which will probably impact the phenotype negatively in patients with aneuploidies.     

COVID-19 y salas de análisis del riesgo en salud pública en cuatro departamentos fronterizos de Colombia

Introduction:

Public health risk management in Colombia is led by the Instituto Nacional de Salud. In the face of the COVID-19 emergency, response actions centered on the implementation of risk analysis rooms and the strengthening of surveillance at points of entry into the country.

Objective:

To analyze the implementation and maintenance phases of the COVID-19 risk analysis rooms in four border departments of Colombia.

Materials and methods:

We conducted a qualitative study of public health risk analysis rooms for COVID-19. We reviewed the documentation and data generated from March to June, 2020, in the departments of Amazonas, Vichada, Guainía, and Putumayo. We did semi-structured interviews with key actors and analyzed the answers using the NVivo plus version 11 application in three cycles: open coding, identification of emerging categories, and modeling by analyzing the identified strengths and weaknesses.

Results:

We identified the components of the incident command structure and the relationships between the public health areas. Strengths were evidenced in the integration of the areas: the management of information in real time, the border surveillance and the capabilities of rapid response teams, while weaknesses appeared in planning, community surveillance, and risk communication processes.

Conclusions:

Risk analysis rooms constitute a joint effort at the national and local levels which has promoted the articulated participation of all actors in the analysis of information and the optimization of an organized response during the COVID-19 pandemic.     

Conflicto armado,contaminación y riesgos en salud: una evaluación de riesgo de tres fuentes de exposición ambiental asociadas con el conflicto en Colombia

Introduction:

Armed conflicts affect territories rich in resources and biodiversity. As a result of the environmental damage caused by violent actions, the health of populations can be affected.

Objectives:

To assess the risks to human health due to environmental degradation associated with three violent actions in the context of the Colombian armed conflict: Pipeline bombing, informal mining with mercury, and spraying of illicit crops with glyphosate.

Materials and methods:

We conducted a quantitative evaluation of the risks to individual health associated with armed conflict activities using methodologies focused on the routes of pollutants dispersion, their concentrations in the environment, the exposure of the individuals, and the risks of carcinogenic and non-carcinogenic effects.

Results:

The risk assessment of the armed conflict-related actions under study evidenced intolerable carcinogenic risk and unacceptable non-carcinogenic risk due to the consumption of water and fish contaminated by polycyclic aromatic hydrocarbons (PAH), mercury, and glyphosate.

Conclusions:

The study reiterates the inextricable connections existing among the environment, society, and health, as well as the implications of environmental violence for the public health of vulnerable population groups and, in general, for the well-being of all living beings affected by the armed conflict.     

Manifestaciones mucocutáneas y su relación con el recuento de linfocitos T CD4 en pacientes infectados con el virus de inmunodeficiencia humana hospitalizados en Medellín,Colombia

Introduction.

About 80-95% of patients infected with the human immunodeficiency virus (HIV) develop skin manifestations, which are markers of the patients’ immune status. Objective. To describe the dermatologic manifestations and the clinical and sociodemographic factors of hospitalized patients diagnosed with HIV and their correlation with CD4 T-lymphocyte count.

Materials and methods.

We conducted an observational, cross-sectional, and retrospective study of the medical records of 227 adult patients with HIV diagnosis evaluated by dermatology in a hospital in Medellín, Colombia.

Results.

We included 227 patient records with 433 dermatologic manifestations, 64.4% of them infectious. The most frequent manifestations were oral candidiasis, condylomata acuminata, and drug reactions. Moreover, a statistically significant relationship was found between disseminated herpes zoster virus and secondary syphilis with a CD4 count between 200-499 cells/mm³ (p=0.04 and 0.028, respectively). There was also a statistically significant relationship between oral candidiasis and a CD4 count of less than 100 cells/ mm³ (p=0.008).

Conclusions.

The relationship between disseminated herpes zoster with CD4 between 200-499 cells/mm³ suggests that, despite having high CD4 counts, severe forms of the disease may occur due to possible T-cell dysfunction and depletion of the immune system. Additionally, the relationship between oral candidiasis and CD4 less than 100 cells/mm³ indicates the potential role of oral candidiasis as an essential marker of weakened immune status in HIV patients.     

Niveles de micronutrientes en niños escolares colombianos e inseguridad alimentaria

Introduction:

Half of the Colombian households experience some degree of food insecurity. Food insecurity has been associated with malnutrition, which could result in micronutrient deficiencies in children; however, the evidence is not conclusive.

Objective:

To examine the associations between food insecurity and blood concentrations of hemoglobin, ferritin, vitamin A, vitamin B12, folate, and zinc in school-age children from Bogotá, Colombia.

Materials and methods:

We conducted a cross-sectional study among 2,660 children aged 5-12 from Bogotá''s public schools. We assessed their household food insecurity level with the Spanish version of the Household Food Security Survey Module (HFSSM), a validated scale, and quantified blood biomarkers of iron, vitamin A, folate, vitamin B12, and zinc status. We examined the associations between food insecurity, severe hunger, and micronutrient status biomarkers using propensity scores.

Results:

Three-quarters of households had some degree of food insecurity and 12 % had food insecurity and severe hunger. Prevalence of marginal vitamin B12 status and vitamin A and zinc deficiencies were, respectively, 17%, 14%, and 1.4%. Compared with children from households without severe hunger, those exposed to it had lower adjusted mean concentrations of vitamin A, vitamin B12, and folate, but these differences were not statistically significant.

Conclusion:

Food insecurity with severe hunger was not associated with micronutrient status biomarkers in Colombian school-age children. The HFSSM may adequately measure hardship in food acquisition due to lack of resources, but it does not yield an index that is associated with micronutrient status biomarkers.     

Membrana de cáscara de huevo para la curación de heridas superficiales en ratones

Introduction:

Eggshell membranes offer beneficial properties for tissue regeneration and their biomedical applications are important.

Objective:

To demonstrate the effectiveness of hen unfertilized eggshell membranes in the treatment of superficial open wounds in mice compared to the conventional procedure.

Materials and methods:

15-mm linear wounds were made on the back of 10 male CF-1 mice. The mice were divided into four groups. One group did not receive any treatment and the other three were given conventional treatment, eggshell membranes dressing, and eggshell membranes powder. The evolution of the wounds was registered by photographs.We measured wounds length and healing time and calculated the length reduction rate and the percentage of healing. The healing percentages were analyzed by ANOVA with a post hoc Dunnett test (p<0.05).

Results:

The treatments with eggshell membranes and membrane powder had a wound- length reduction rate of 1.009 and 1.020 mm/day, greater than the conventional treatment, of 0.852 mm/day, and a healing time of 12 days, i.e., less than the 16-day conventional treatment. The statistical analysis showed significant differences between eggshell membrane treatments and the conventional treatment.

Conclusions:

Eggshell membrane dressing and eggshell membrane powder applied to open superficial wounds in mice were more effective than the conventional treatment in regenerating injured tissue in mice.
