ABSTRACT
Resumen: Los datos preliminares confirman el impacto psicológico que la crisis por COVID-19 está provocando en niños y adolescentes de población comunitaria. Se desconoce cómo afecta a la población infantil que sufre maltrato intrafamiliar. El objetivo del estudio fue examinar el impacto emocional adicional que supone la medida de confinamiento en menores de edad expuestos a violencia de pareja hacia la mujer que recibían atención psicológica en la Región de Murcia. Ciento ochenta y cinco madres informaron vía telefónica cómo el confinamiento afectó a 269 niños/as de entre 0 y 18 años. También los 108 menores que tenían 6 años o más, cumplimentaron el listado sobre su propio estado emocional. El incremento en la incidencia de alteraciones psicológicas en esta población ha sido baja (1.1-4.8%), si bien entre aquellos que aumentó la sintomatología predominaron la desorganización comportamental y la alteración emocional. Asimismo, se comprobó que algunas variables (sexo, edad, días de confinamiento, conflicto familiar) contribuyeron al incremento de desorganización comportamental y estrés traumático/depresión. Es preciso desarrollar más trabajos en esta línea por las implicaciones que se pueden derivar tanto a nivel de diagnóstico como de tratamiento.
Abstract: Preliminary data confirm the psychological impact that the COVID-19 crisis is causing in children and adolescents in the community population. It is unknown how it affects the child population who suffer intrafamilial abuse. The objective of the study was to examine the additional emotional impact of the measure of confinement in minors exposed to intimate partner violence towards women who received psychological attention in the Region of Murcia. One hundred and eighty-five mothers reported, by telephone comunication, how the confinement affected to 269 children between the ages of 0 and 18. Also the 108 minors who were 6 years old or older completed the list on their own emotional state. The incidence increasement of psychological disorders within this population has been low (1.1-4.8%), although among those with increased symptoms, behavioral disorganization and emotional disturbance was predominant. Likewise, it was found that some variables (sex, age, days of confinement, family conflict) contributed to increase the behavioral disorganization and traumatic stress/depression. It is necessary to develop more research in this line due to the derived implications both at diagnosis and treatment levels.

INTRODUCTION: The treatment of metastatic castration-resistant prostate cancer (mCRPC) has changed significantly in recent years. Inhibitors of androgen receptors have shown especially significant benefits in overall (OS) and progression-free survival (PFS), with a good toxicity profile. Treatment selection depends on the patient's individual clinical, radiological, and biological characteristics. OBJECTIVE: To describe treatment outcomes (efficacy, toxicity) in a cohort of patients with mCRPC in Spain. MATERIALS AND METHODS: Multicenter, retrospective study of patients with mCRPC included in a database of the Urological Tumour Working Group (URONCOR) of the Spanish Society of Radiation Oncology (SEOR). Metastatic CRPC was defined according to the prostate cancer working group 3 (PCWG3) criteria. The Kaplan-Meier technique was used to evaluate OS and the Common Terminology Criteria for Adverse Events (CTCAE, v.4.0) were used to assess toxicity. Univariate and multivariate Cox regression analyses were performed to identify the factors significantly associated with OS. RESULTS: A total of 314 patients from 17 hospitals in Spain diagnosed with mCRPC between June 2010 and September 2017 were included in this study. Mean age at diagnosis was 68 years (range 45-89). At a median follow-up of 35 months, OS at 1, 3, and 5 years were 92%, 38%, and 28%, respectively. Grades 1-2 and grade 3 toxicity rates were, respectively, 68% and 19%. No grade 4 toxicities were observed. On the multivariate analysis, the following factors were significantly associated with OS: age (hazard ratio [HR] 0.42, p = 0.010), PSA value at diagnosis of mCRPC (HR 0.55, p = 0.008), and Gleason score (HR 0.61, p = 0.009). CONCLUSIONS: Age, Gleason score, and PSA at diagnosis of mCRPC are independently associated with overall survival in patients with mCRPC. The efficacy and toxicity outcomes in this patient cohort treated in radiation oncology departments in Spain are consistent with previous reports.

Phenotype-linked fertility hypothesis (PLFH) predicts that male secondary sexual traits reveal honest information about male fertilization ability. However, PLFH has rarely been studied in humans. The aim of the present study was to test PLFH in humans and to investigate whether potential ability to select fertile partners is independent of sex or cultural background. We found that on the contrary to the hypothesis, facial masculinity was negatively associated with semen quality. As increased levels of testosterone have been demonstrated to impair sperm production, this finding may indicate a trade-off between investments in secondary sexual signalling (i.e. facial masculinity) and fertility or status-dependent differences in investments in semen quality. In both sexes and nationalities (Spanish and Colombian), ranked male facial attractiveness predicted male semen quality. However, Spanish males and females estimated facial images generally more attractive (gave higher ranks) than Colombian raters, and in both nationalities, males gave higher ranks than females. This suggests that male facial cues may provide culture- and sex-independent information about male fertility. However, our results also indicate that humans may be more sensitive to facial attractiveness cues within their own populations and also that males may generally overestimate the attractiveness of other men to females.

The purpose of this study was to describe the practice of pica during pregnancy in Argentine women. Maternal and fetal characteristics as well as the practice of pica were evaluated during the puerperium in a sample of 1,014 women from five different geographical areas. Pica prevalence for the total sample was 23.2% (95% CI 20.6-25.8). Pagophagia (ice consumption) was the main type of pica practice, followed by geophagia (earth intake) and the ingestion of soap, toothpaste and chalk. The onset of the practice was mainly in the first months of pregnancy. A total of 49.8% of women revealed a family history of pica; 30.6% had pica in childhood and 13.2% suffered from polypica. Women with pica during pregnancy had similar age, pre-pregnancy body mass index (BMI), parity, neonatal birth weight and gestational age compared with non-pica mothers, although maternal haemoglobin concentration was lower in women with pica than in non-pica mothers (p = 0.0001).

OBJECTIVE: The aim of this investigation was to know and assess the characteristics of nutrient intake in pregnant women diagnosed with pica (consumption of non nutritive substances). MATERIALS AND METHODS: We studied a group of 71 women presenting pagophagia (compulsive consumption of ice) and other forms of pica, which was compared to a control group including the same number of women with similar socio-cultural and anthropometrical characteristics but without the eating disorder. Both groups were randomly selected among women assisted at the Hospital de la Matanza, province of Buenos Aires, Argentina. RESULTS: we did not observed statistically significant differences in energy, total proteins, iron, and calcium consumption. However, women with pica showed lower intakes (p < 0.03) of carbohydrates, animal proteins, hemic iron, and zinc. The median values for women with and without the disorder were, respectively: carbohydrates (g): 379/426; animal proteins (g): 35/39; hemic iron (mg): 1.5/1.9; zinc (mg): 7.1/8.1, calcium (mg): 625/612. In both groups, meat was the main source of iron and zinc, and its intake was lower in the group with pica. The daily average amounts consumed were 117 + 53 g for women with pica and 154 + 71 g (p < 0.03) for the control group. Only 22% of pregnant women with the disorder referred using iron supplements during their pregnancy. CONCLUSIONS: As compared with control women, pregnant women with pica disorder showed lower intake in traditionally marginal nutrients such as iron and zinc. These results show the need for early diagnosing this disorder during pregnancy in order to prevent or correct it and properly counseling pregnant women about food selection and supplementation regimens.

To examine the genetic features of the long terminal repeat (LTR) derived from six HIV-1-infected individuals enrolled in the Mexico City Cohort, we cloned and sequenced a 505-bp fragment of the proviral LTR from their peripheral blood mononuclear cells (PBMCs). All patients harbored HIV-1 LTR quasispecies corresponding to the B subtype. Three patients with high CD4+ T cell counts (>500/mm3) presented LTR sequences with point mutations in the TAR bulge. The LTR sequence from a patient classified as a long-term nonprogressor (LTNP) presented the most frequent naturally occurring length polymorphism (MFNLP) and two substitutions in the TAR region that were predicted to result in two alternative secondary RNA structures. A novel 18-bp deletion, which eliminates part of the putative binding site for the nuclear factor of activated T cells (NFAT-1), was identified in the overlapping nef/LTR sequence derived from a patient progressing to AIDS. This deletion coincides with the ability of this virus to consistently replicate at low levels in vivo (viral load <500 RNA copies/ml) and in vitro (unsuccessful virus isolation). On one occasion, when virus isolation was successful, the 18-bp deletion was no longer evident and LTR sequences with intact NFAT-1-binding sites were observed. Inoculation of hu-PBL-SCID mice with viruses from several Mexican patients resulted in differential CD4+ T cell depletion patterns 15 days postinfection, which agree with the in vivo CD4+ T cell count data from each patient.

The iron (Fe) nutritional status of 203 healthy pregnant women was assessed at the first prenatal visit (To) (gestational age: 16.9 weeks +/- 3.81. Women were randomly assigned to one of three groups: G1 and G2 were supplemented with ferrous fumarate (60 mg elemental Fe) daily or intermittently (three times a week), respectively; and GC was the control group, without supplementation. The follow up was carried out until 34-37 weeks of gestational age (Tf), but only 43% of pregnant women completed the trial. At To and Tf fasting blood samples were collected and Hematocrit (Hct), Hemoglobin (Hb), Erythrocyte Protoporphyrin (EP) and Serum Ferritin (FERR) were determined. The percentage of women with abnormal biochemical values at To (n = 203) was: Hb (g/dl) < 10.5: 2.6%; PE (microgram/dl of red blood cells) > 70: 4.8%; FERR (ng/ml) < 10: 4.4%. Results (X +/- DE) of women that completed the follow up were at To and Tf, respectively: Hct (%): GC: 37.7 +/- 3.4 and 36.0 +/- 3.2 (p < 0.05); G1: 38.8 +/- 2.2 and 38.0 +/- 2.6; G2: 39.0 +/- 2.7 and 37.7 +/- 3.7; Hb (g/dl): GC: 12.5 +/- 1.2 and 11.9 +/- 1.3 (p < 0.05); G1: 12.6 +/- 1.1 and 12.8 +/- 1.1; G2: 12.9 +/- 0.9 and 12.2 +/- 1.5; PE (microgram/dl red blood cells): GC: 30 +/- 17 and 43 +/- 22 (p < 0.01); G1: 26 +/- 13 and 38 +/- 21 (p < 0.01); G2: 26 +/- 16 and 31 +/- 26; FERR (ng/ml): GC: 75 +/- 67 and 31 +/- 49 (p < 0.01); G1: 46 +/- 34 and 19 +/- 10 (p < 0.01); G2: 43 +/- 11 and 11 +/- 7 (p < 0.01). These results show: a) Fe administration was efficient to mitigate Hb decrease; b) Fe stores decreased during pregnancy regardless of Fe supplementation and frequency; c) EP values indicate that intermittent Fe administration was more efficient to maintain normal erythropoiesis.

The present work explores the use of image digitalization of western blot (WB) aiming to extract more information about the humoral immune response of human immunodeficiency virus (HIV) infected individuals, and to analyze obtained data in a multivariate manner. The digitalization and analysis of WB images was performed on 115 sera. Images were analyzed either qualitatively: dendogram and principal component analysis (PCA) or quantitatively: PCA of the total bands, taking either the antigens, which belong to the virus, or only those which do not. Results show the feasibility of mechanical diagnosis of a large number of WB images. The dendogram and the qualitative PCA satisfactorily separated white images, images with less than four bands, and images with more complex patterns. Quantitative analysis, which keeps more information, separated the images of negative, undetermined and positive diagnosis quite precisely. It was also found that the positive images with complex patterns of antigen recognition correlate better with asymptomatic individuals. Image analysis also revealed various other bands in WB which do not seem to correspond to viral proteins and could represent autoantigens or crossed antigens between HIV and humans which may cause autoimmunity. Digital analysis of WB images is thus demonstrated to be of great usefulness in the diagnosis and of potential great interest in following the evolution and exploring the pathogenesis of AIDS.

The iron (Fe) nutritional status was studied in 113 healthy pregnant women, age: 24.8 +/- 6.1 Ys. During the second trimester (gestational age: 16.9 +/- 3.8 weeks), a 24 h dietary recall was carried out and daily Fe intake was calculated, according to Latinoamerican and German Food Composition Tables. On the same day, hematocrit (Hct), hemoglobin (Hb), erythrocyte protoporphyrin (EP) and serum ferritin (SF) were determined in fasting blood samples. Mean daily Fe intake was 10.8 +/- 4.6 mg. The percentage of population with abnormal biochemical values was: Hb (g/dL) < 10.5: 2%; PE > 70 microgram/dL of red blood cells: 6.5%; SF (ng/mL) < 12-20: 16%. According to the new recommendations of the American Institute of Medicine, Fe supplementation would be necessary in women with SF < 20 ng/ml (22%). Therefore, the follow-up of iron stores would be necessary in those with SF > 20 ng/mL before Fe administration.

The reactivities of 1,172 serum samples obtained from asymptomatic human immunodeficiency virus type 1 (HIV-1)-positive and HIV-1-negative individuals residing in Mexico to a synthetic disulfide-looped peptide from the HIV-1 gp41 (amino acids 602 to 616 [IWGCSGKLICTTAVP] were examined by an enzyme-linked immunoadsorbent assay (ELISA) procedure. Antibodies to the synthetic peptide were detected in 261 of 268 serum samples from HIV-positive individuals (sensitivity, 97.4%). The peptide also reacted with 12 of 904 serum samples from control HIV-negative individuals (specificity, 98.7%). Western blots (immunoblots) of four of the seven serum samples that produced false-negative results in the ELISA showed that three of them reacted weakly with gp41 and strongly with gp120, p55, and/or p24. Potential diagnostic difficulties raised by the reported C1q binding capacity of this peptide were also evaluated: few and weak false-positive results were found among sera from patients with rheumatoid arthritis (1 of 31) and neurocysticercosis (2 of 111). In fact, strong reactivity with the peptide spotted an undetected HIV infection underlying clinical neurocysticercosis.
