RESUMEN

Background: There are no studies that measure the prevalence and real comorbidities of neurodevelopmental disorders (NDDs) according to the DSM-5-TR in 6-year-old children in population and clinical samples or studies that measure them as a whole. The data on the prevalence of these disorders are usually disparate because of the estimation methods (direct/indirect), the type of sample (population/clinical/school), and the ages studied. Methods: The initial sample (289 subjects) was representative of 6-year-old children in the entire population of Menorca, obtained from pediatric primary care services (100% of the sample). The patients were divided into two groups based on the criterion of verification of clinical warning signs. One of the groups represented the clinical or experimental sample (EG) (81 subjects) at risk of NDDs; the other group was considered the control sample (CG) (210 subjects), and they were subjects without risk of suffering NDDs. A direct clinical assessment of the clinical sample was carried out, and they were administered the Wechsler Intelligence Scale for Children (WISC-V), the Clinical Evaluation of Language Fundamentals (CELF-5), the Battery for the evaluation of the processes of revised reading (Batería para la evaluación de los procesos de lectura revisada - PROLEC-R), the Test for the Diagnosis of Basic Mathematical Competences, (TEDI-MATH), and the Developmental Coordination Disorder Questionnaire (DCDQ). Results: A total of 21.5% of the initial sample suffered from an NDD. A total of 2.4% presented autism spectrum disorder (ASD); 14% presented attention-deficit hyperactivity disorder (ADHD); 0.34% presented mild intellectual disability; 9.54% presented communication disorder (CD) (5.8% language disorder, 3.4% phonological disorder, and 0.34% stuttering); 10% presented learning disorder with reading difficulties; 5.8% presented learning disorder with difficulties in writing; 3.11% presented learning disorder with difficulties in mathematics; 1% presented transitory tic disorder; 0.34% presented chronic tic disorder; 1% presented Tourette syndrome; 2% presented motor coordination disorder (MCD); and 0.34% presented stereotypic movement disorders. Male children were more affected than female children in general, with male/female ORs of 0.14/0.92 for the presence of comorbidities, 0.11/0.88 for combined ADHD, 0.06/0.87 for language disorder, 1.02/1.27 for MCD, and 1.39/1.02 for inattentive ADHD. Conclusion: In disadvantaged contexts, there was a higher prevalence of NDDs and comorbidities, unless the disorder was extreme, in which case only the NDD manifestations were presented. A significant proportion of the sample had not been previously diagnosed (88.6%); therefore, early detection programs are recommended to identify warning signs and develop policies that help and support the most disadvantaged sectors of the population.

RESUMEN

Background: Endometrial Cancer (EC), the most common genital tract malignancy in women, is recognised to be associated with a high Body Mass Index (BMI). Objective: The aim of the study was to evaluate the impact of obesity on intra and post-operative morbidity for patients treated for EC. Materials and Methods: This was a retrospective observational study including patients with EC that were surgically treated at Hospital de la Santa Creu i Sant Pau during nine consecutive years. The patients were divided in groups according to BMI: <30 Kg/m2, ≥30-<40 Kg/m2 and ≥40 Kg/m2. Demographic and pathological characteristics, surgical outcomes, perioperative complications and long-term outcomes were recorded. Results: The study included 290 patients; 164 patients with BMI <30 Kg/m2(56.5%), 107 patients with ≥30-<40 Kg/m2 36.9%) and 19 patients with ≥40 Kg/m2(6.65%). Patients with BMI ≥40Kg/m2 were younger, presented a higher percentage of endometrioid histology (84.2%, p<0.01), well-differentiated tumours (73.7%, p<0.01) and were more frequently in the initial stages at diagnosis (94.7%) compared to the other groups. A significant percentage of the patients were operated on laparoscopically (88.7%, 88.8%, 94.7% respectively). No significant differences were found in the evaluation of the surgical outcomes. The results relative to complications showed an overall tendency toward increase in the ≥40 Kg/m2 BMI group but no statistical differences were identified among the groups in terms of complications or long-term outcomes. Conclusions: There was a rising trend towards increased complications with increasing BMI in the study population, however, this was found not to be statistically significant. Therefore, the optimisation of co-morbidities and the adaptation of surgical treatment is important for the management of obese patients with endometrial cancer. What is new?: The study allows the comparison between groups with different BMI in patients with endometrial cancer. Different surgical outcomes, intra operative, early, and late complications are clearly identified, and survival outcomes are also investigated in our study.

RESUMEN

PURPOSE OF REVIEW: Cerebral palsy (CP) is a group of disorders caused by non-stabilized cerebral lesions. Individuals with this disorder are at a higher risk of suffering from malnutrition and other related detrimental effects to their quality of life. For this reason, accurate methods of nutritional assessment are vital for people suffering from this condition. While assessment of nutritional status in children with CP has been extensively studied, very few studies have been carried out on adults. These limitations are due to the great anatomical-functional variability characteristic of this syndrome. Difficulties that derive from this variability in adult patients with CP mean that there remains an urgent need for certain standards of nutritional assessment for this population. The objective of this review is to compile the latest trends in nutritional assessment in adults with CP to guide the development of a conceptual framework for future research. RECENT FINDINGS: With this aim, relevant studies have been identified. The most commonly used technique to evaluate nutritional status is the BMI because of its ease-of-use. However, its well-known limitations fail to adequately estimate the nutritional status in this population, with measurements of patients with CP yielding results that are much less accurate than those that already exist in the general population. Although more studies are needed, kinanthropometry is considered one of the most reliable techniques; nevertheless, the anatomical limitation characteristic of CP plays a limiting factor.

RESUMEN

OBJECTIVE: To interpret the current evidence on the prevalence of neurodevelopmental disorders (NDDs) through a systematic review based on both DSM-5 (2013) and PRISMA criteria. METHOD: Empirical studies complying with the PRISMA guidelines were identified from four databases (PubMed, Scopus, Science Direct, and ProQuest) and systematically reviewed. In total, 17 articles were selected for the study. RESULTS: In the scientific literature, there have been only a few studies measuring the prevalence of NDDs according to the DSM-5 (2013) criteria in people under 18 years old. The reported prevalence rates were as follows: intellectual disability (ID), 0.63%; attention-deficit/hyperactivity disorder (ADHD), 5-11%; autism spectrum disorder (ASD), 0.70-3%; specific learning disorder (SLD), 3-10%; communication disorders (CDs), 1-3.42%; and motor disorders (MDs), 0.76-17%. Although there is extensive literature on specific disorders, NDDs have rarely been assessed as a whole. All of the reviewed studies support the idea that such disorders can be considered chronic, heterogeneous, underdiagnosed conditions and that comorbidity of multiple NDDs is the norm. Likewise, it is estimated that the prevalence of the most studied disorders, such as ADHD, ASD and SLD, remains stable over time and is consistent in different cultures, ages, ethnicities and sexes. CONCLUSION: The studies reviewed lead us to conclude that the prevalence rate of NDDs fluctuates globally between 4.70 and 88.50%; these variations depend on methodological aspects such as estimation procedures, as well as on sociocontextual phenomena. It is also important to consider that the prevalence found is probably highly influenced by the activity of the countries in the diagnosis and training of professionals who care for children and adolescents. Hence, there is a need for a secondary intervention in the fields of public health and education to minimize socioemotional consequences, prevent academic failure, and reduce the economic cost to society.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: The pneumococcal urinary antigen test enables rapid bacteriological diagnosis in respiratory tract infections. The objective was to identify factors associated with a positive pneumococcal urinary antigen test result. PATIENTS AND METHODS: This seven-year retrospective monocentric study was performed on consecutive patients presenting with respiratory tract infections reported as pneumococcal-positive. Epidemiological, biological, and radiological factors were analyzed, and severity scores were calculated. RESULTS: A total of 223 patients were included. Significant associations were observed between positive test results and age over 65years (P=0.01), positive test results and immunosuppression factors (blood disease [25% Ag+ group vs. 4% Ag- group, P=0.001], immunosuppressive therapy [10% Ag+ group vs. 0% Ag- group, P=0.02]). Clinically, fever (64% Ag+ group vs. 42% Ag- group, P=0.01) and cough (46% Ag+ group vs. 19% Ag- group, P<0.01) were associated with a positive result, as were radiological alveolar opacities (67% Ag+ group vs. 44% Ag- group, P=0.01). High PSI score was associated with the Ag+ group (79% vs. 56% Ag- group, P=0.001). CONCLUSION: Age, immunosuppressive factors, typical pneumococcal symptoms, and PSI scores were associated with a positive pneumococcal urinary antigen result.

RESUMEN

We report the first two cases of tuberculous coinfection with Mycobacterium tuberculosis and M. canettii. Both patients were young Djiboutian females with pulmonary tuberculosis (TB). One had a miliary pattern with concomitant human immunodeficiency virus infection. Both recovered completely with a standard four-drug anti-tuberculosis treatment regimen. Due to the different natural reservoirs and routes of infection of these two strains, our study supports the common belief that multiple strains of infection in TB are related to superinfection rather than concomitant infection.

RESUMEN

BACKGROUND: This study aimed to describe the microbiological epidemiology of repatriated French soldiers with an open traumatic injury, and to measure the proportion of multidrug-resistant bacteria (MDRB). METHODS: Retrospective study including all French soldiers repatriated in 2011 and 2012 in Parisian military hospitals for open traumatic injury. Results of clinical samples and MDRB screening were collected. The antibiotic susceptibility was assessed using the agar disk diffusion method. Characterization of resistance mechanisms was performed using PCR. Genotyping of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) isolates was performed using rep-PCR. RESULTS: A total of 139 patients were included; 70% of them were repatriated from Afghanistan. At admission, 24/88 were positive for MDRB (28%), mainly ESBL-E but no carbapenemase-producing Enterobacteriaceae and vancomycin-resistant Enterococcus faecium were identified. Forty-five patients had lesion sample collection, and 28/45 had a positive culture. The most frequently isolated pathogens were Enterobacter cloacae, Pseudomonas aeruginosa, and Escherichia coli. For eight patients, a MDRB was isolated from the wound, mainly ESBL-E (7/8) but also one methicillin-resistant Staphylococcus aureus and one imipenem-resistant Acinetobacter baumannii. Among ESBL-E, the PCR evidenced the high prevalence of CTX-M15 enzymes. Rep-PCR performed on the 23 ESBL-producing E. coli isolates highlighted numerous profiles. CONCLUSIONS: Controlling the spread of ESBL-E is currently challenging for French Armed Forces. Despite any evidence of an epidemic clone, a high-level compliance with hygiene precautions is required throughout the chain of care to avoid cross contamination.

RESUMEN

The aim of the present study was to determine whether there is an association between the kinematic sperm subpopulations and fluorescent groups in bulls using a new fluorescent staining method that allows classification of spermatozoa into groups depending on their acrosomal and membrane integrity, as well as functional status, without inhibiting sperm motility. Cryopreserved semen samples from 10 Holstein bulls were used in the study. A multiparametric analysis of results obtained by the ISAS 3Fun kit (Proiser) was performed. The different fluorescent groups were detected and their motility characteristics evaluated using ISAS software. Clustering procedures using the kinematic data resulted in the classification of spermatozoa into three kinematic sperm subpopulations. The distribution of kinematic sperm subpopulations was different between the fluorescent sperm groups (P<0.001), although the correlation between them was low (r=0.113; P<0.01).

RESUMEN

Sperm motility is one of the most widely used parameters of sperm quality. Computer-aided sperm motility analysis (CASA-Mot) systems were developed to reduce the subjectivity of sperm motility assessment, and have had broad scientific and practical acceptance. In this review, the sources of variation and current applications of this technology and its relationships with other sperm quality tests are described in detail. Despite remarkable advances in the technique, there is still great need for standardisation in many species, and the numerous factors that affect the results make it difficult to provide universally accepted criteria for classifying semen samples based on sperm motility characteristics. The main fields for CASA-Mot include the study of male fertility and pathologies, evaluation of the effects of physical and chemical agents, improvement of epidemiological survey studies, more precise calculation of seminal doses for farm animals, realisation of basic studies about sperm function, improvement of sperm technologies such as cryopreservation and quality control analysis. Numerous relationships have been established between CASA-Mot and other sperm quality tests, although most of these parameters are complementary. Future CASA-Mot systems will probably be able to integrate several sperm quality parameters with motility.

RESUMEN

BACKGROUND: The diagnostic accuracy of the parent report of the Montgomery-Åsberg Depression Rating Scale (MADRS-P) for the screening of major depressive disorder (MDD) in adolescents has not been evaluated. AIM: The aim was to explore the psychometric properties and diagnostic accuracy of the MADRS-P in general child and adolescent psychiatric outpatient services in Sweden. METHOD: The study was a validation and a diagnostic accuracy study. Consecutive adolescent psychiatric patients (n = 101, 45 males, mean age 15 years) were assessed with a diagnostic interview, the Kiddie Schedule of Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime version (K-SADS-PL), as a reference test. Thereafter, their parents reported on the MADRS-P. Both categorical MDD diagnoses and dimensional MDD symptom severity scores were obtained from the K-SADS-PL. RESULTS: The internal consistency of the MADRS-P, measured with Cronbach's alpha, was 0.846. The concurrent validity, assessed by Spearman's rho as a correlation between the K-SADS MDD symptom severity score and the MADRS-P score, was 0.580. The area under the curve in a receiver operating characteristic analysis for all participants was 0.786 (95% confidence interval 0.694-0.877, p < .001). At a cut-off of 10, sensitivity was 0.86, specificity 0.54, positive predictive value 0.59 and negative predictive value 0.84. CONCLUSIONS: The parent-rated MADRS-P showed similar psychometric properties as previously shown for the self-rated MADRS-S in adults. Although the MADRS-P has acceptable diagnostic accuracy for screening for MDD in adolescents in a general psychiatric setting, it cannot be used alone for diagnosing MDD.

RESUMEN

There is a need to develop more integrative sperm quality analysis methods, enabling researchers to evaluate different parameters simultaneously cell by cell. In this work, we present a new multi-parametric fluorescent test able to discriminate different sperm subpopulations based on their labeling pattern and motility characteristics. Cryopreserved semen samples from 20 Holstein bulls were used in the study. Analyses of sperm motility using computer-assisted sperm analysis (CASA-mot), membrane integrity by acridine orange-propidium iodide combination and multi-parametric by the ISAS®3Fun kit, were performed. The new method allows a clear discrimination of sperm subpopulations based on membrane and acrosomal integrity, motility and morphology. It was also possible to observe live spermatozoa showing signs of capacitation such as hyperactivated motility and changes in acrosomal structure. Sperm subpopulation with intact plasma membrane and acrosome showed a higher proportion of motile sperm than those with damaged acrosome or increased fluorescence intensity. Spermatozoa with intact plasmalemma and damaged acrosome were static or exhibit weak movement. Significant correlations among the different sperm quality parameters evaluated were also described. We concluded that the ISAS®3Fun is an integrated method that represents an advance in sperm quality analysis with the potential to improve fertility predictions.

RESUMEN

Several factors unrelated to the semen samples could be influencing in the sperm motility analysis. The aim of the present research was to study the effect of four chambers with different characteristics, namely; slide-coverslip, Spermtrack, ISAS D4C10, and ISAS D4C20 on the sperm motility. The filling procedure (drop or capillarity) and analysis time (0, 120 and 240s), depth of chamber (10 or 20µm) and field on motility variables were analysed by use of the CASA-mot system in goat sperm. Use of the drop-filling chambers resulted in greater values than capillarity-filling chambers for all sperm motility and kinetic variables, except for LIN (64.5% compared with 56.3% of motility for drop- and capillarity-filling chambers respectively, P<0.05). There were no significant differences in total sperm motility between different chamber depths, however, use of the 20µm-chambers resulted in greater sperm progressive motility rate, VSL and LIN, and less VCL and VAP than chambers with a lesser depth. There was less sperm motility and lesser values for kinetic variables as time that elapsed increased between sample loading and sperm evaluation. For sperm motility, use of droplet-loaded chambers resulted in similar values of MOT in all microscopic fields, but sperm motility assessed in capillarity-loaded chambers was less in the central fields than in the outermost microscopic fields. For goats, it is recommended that sperm motility be analysed using the CASA-mot system with a drop-loaded chamber within 2min after filling the chamber.

RESUMEN

To save energy, the European directives from the Eco-design of Energy Using Products (2005/32/CE) have recommended the replacement of incandescent lamps by more economic devices such as Light Emitting Diodes (LEDs). However, the emission spectrum of these devices is enriched in blue radiations, known to be potentially dangerous to the retina. Recent studies showed that light exposure contributes to the onset of early stages of age-related macular degeneration (AMD). Here, we investigate, in albinos and pigmented rats, the effects of different exposure protocols. Twenty-four hours exposure at high luminance was compared to a cyclic (dark/light) exposure at domestic levels for 1week and 1month, using different LEDs (Cold-white, blue and green), as well as fluorocompact bulbs and fluorescent tubes. The data suggest that the blue component of the white-LED may cause retinal toxicity at occupational domestic illuminance and not only in extreme experimental conditions, as previously reported. It is important to note that the current regulations and standards have been established on the basis of acute light exposure and do not take into account the effects of repeated exposure.

RESUMEN

In nursery pollination mutualisms, which are usually obligate interactions, olfactory attraction of pollinators by floral volatile organic compounds (VOCs) is the main step in guaranteeing partner encounter. However, mechanisms ensuring the evolutionary stability of dioecious fig-pollinator mutualisms, in which female fig trees engage in pollination by deceit resulting in zero reproductive success of pollinators that visit them, are poorly understood. In dioecious figs, individuals of each sex should be selected to produce odours that their pollinating wasps cannot distinguish, especially since pollinators have usually only one choice of a nursery during their lifetime. To test the hypothesis of intersexual chemical mimicry, VOCs emitted by pollen-receptive figs of seven dioecious species were compared using headspace collection and gas chromatography-mass spectrometry analysis. First, fig-flower scents varied significantly among species, allowing host-species recognition. Second, in species in which male and female figs are synchronous, intersexual VOC variation was not significant. However, in species where figs of both sexes flower asynchronously, intersexual variation of VOCs was detectable. Finally, with one exception, there was no sexual dimorphism in scent quantity. We show that there are two ways to use scent to be a dioecious fig based on differences in flowering synchrony between the sexes.

RESUMEN

INTRODUCTION: Mycobacterium simiae pulmonary infections remain exceptional in France. CASE REPORT: We report a case of M. simiae lung infection and a 10-year follow-up in a non-immunocompromised host. CONCLUSION: This case emphasizes the difficulties of choosing the appropriate drugs and their side effects in the absence of any existing gold standard.
