Impacts of violence on the mental health of Afro-descendant survivors in Colombia

The Colombian armed conflict has disproportionately affected minorities, especially afro-Colombian communities. However, there is a lack of evidence about mental health of victims. This study aims to describe the prevalence of mental illness and its associated factors in Afro-descendant violence survivors in Buenaventura and Quibdó, Colombia. A cross-sectional study was carried out using data from a previous trial which aimed to reduce mental health symptoms (ClinicalTrials.gov: NCT01856673). Data of 710 adults identified through a snowball sampling technique was analysed. Diagnoses of depression, anxiety, post-traumatic stress disorder (PTSD), and dysfunction were established using adapted versions of the Hopkins Symptoms Checklist and the Harvard Trauma Questionnaire, plus variables identified in a qualitative study. Multivariate regressions were used to identify associated factors with these diagnoses. The prevalence of depression, anxiety and PTSD in both cities was 26.62% (95% confidence interval [95%CI]: 20.30;23.89), 36.53% (95%CI: 30.63;42.36), and 39.15% (95%CI: 33.36;44.83), respectively. Being married and having registered with the government as victim of the conflict were found to be protective factors for depression and PTSD, respectively. Psychological trauma, unemployment, and traumatic experiences, amongst others, were found as risk factors. The Colombian armed conflict, plus disparities and social exclusion, may be associated with mental health morbidity.

Valor predictivo positivo del diagnóstico prenatal invasivo para alteraciones cromosómicas

Introducción. El diagnóstico prenatal (DP) invasivo para alteraciones cromosómicas (AC) se realiza según las indicaciones de las pruebas no invasivas y se basa en la probabilidad de encontrar un cariotipo alterado.Objetivos. Identificar las indicaciones para la realización de un procedimiento invasivo con el fin de hacer un DP de AC, calcular el valor predictivo positivo (VPP) de cada indicación y estimar la oportunidad relativa (OR) de encontrar una AC.Materiales y métodos. Estudio transversal que caracterizó las indicaciones de procedimientos invasivos para realizar cariotipos en registros de un centro de diagnóstico genético en Cali, Colombia, en el período 2013-2015.Resultados. De 738 registros de cariotipos analizados, 103 (14.0%) tuvieron AC. Las indicaciones más frecuentes fueron alteración anatómica única en ecografía del segundo trimestre (21.4%) y edad materna (18.8%). Las indicaciones con mayor VPP fueron sonolucencia nucal alterada más otro marcador ecográfico (80.0%) y antecedente de 2 o más abortos (30.8%). Las más altas OR de un cariotipo alterado también fueron la sonolucencia nucal más otro marcador ecográfico (OR=1381.6) y el antecedente de 2 o más abortos (OR=153.5).Conclusiones. La ecografía fue la principal herramienta para indicar procedimientos invasivos de DP. Los marcadores bioquímicos integrados fueron una indicación poco frecuente.

Tremor-Ataxia Syndrome and Primary Ovarian Insufficiency in an FMR1 Premutation Carrier

Introduction:

The FMR1 gene has four allelic variants according to the number of repeats of the CGG triplet. Premutation carriers with between 55 and 200 repeats are susceptible to developing pathologies such as tremor and ataxia syndrome (FXTAS) and fragile X-associated primary ovarian insufficiency (FXPOI) syndrome.

Case description:

The patient was a 53-year-old female farmer with severe tremor in the upper limbs at rest that worsens with movement, tremor in the jaw and tongue, and generalized cerebral atrophy. She is a carrier of the FMR1 premutation diagnosed by PCR and Southern Blot, complying with the clinical and radiological criteria of FXTAS, and in addition, has a history of vagal symptoms suggestive of ovarian failure and menstrual cycle disorders that led to hysterectomy at age 33 and was subsequently diagnosed with FXPOI.

Conclusion:

An unusual case of FXTAS and FXPOI complying with clinical and radiological criteria is reported in a premutation carrier of the FMR1 gene.

Evaluation of prenatal diagnosis of congenital defects by screening ultrasound, in Cali, Colombia

Introduction The study aim was to determine the frequency of prenatal ultrasound diagnosis of congenital anomalies in Newborns (NB) with birth defects hospitalized in two Neonatal Intensive Care Units (NICU) of Cali (Colombia) and to identify socio-demographic factors associated with lack of such diagnosis. Patients and methods It was an observational cross-sectional study. NB with congenital defects diagnosable by prenatal ultrasound (CDDPU), who were hospitalized in two neonatal intensive care units (NICU), were included in this study. A format of data collection for mothers, about prenatal ultra-sonographies, socio-demographic data and information on prenatal and definitive diagnosis of their conditions was applied. Multiple logistic and Cox regressions analyses were done. Results 173 NB were included, 42.8% of cases had no prenatal diagnosis of CDDPU; among them, 59.5% had no prenatal ultrasound (PNUS). Lack of PNUS was associated with maternal age, 25 to 34 years (Odds Ratio [OR]: 4.41) and 35 to 47 years (OR: 5.24), with low levels of maternal education (OR: 8.70) and with only a PNUS compared to having two or more PNUS (OR: 4.00). Mothers without health insurance tend to be delayed twice the time to access the first PNUS in comparison to mothers with payment health insurance (Hazard Ratio [HR]: 0.51). Among mothers who had PNUS, screening sensitivity of CDDPU after the 19thgestational week was 79.2%. Conclusions The frequency of prenatal diagnosis is low and is explained by lack of PNUS, or by lack of diagnostic in the PNUS. An association between lack of PNUS and late age pregnancy and low level of maternal education was found. In addition, uninsured mothers tend to delay twice in accessing to the first PNUS in comparison to mothers with health insurance. It is necessary to establish national policies which ensure access to appropriate, timely and good quality prenatal care for all pregnant women in Colombia.
