Estudio piloto: contacto padre-hijo(a) y oxitocina en varones preparados especialmente para el nacimiento / Pilot study: father-child contact and oxytocin in males with a special education for childbirth

INTRODUCCÍON: Los padres se han involucrado cada vez más en el embarazo y el nacimiento de sus hijos, pero aún se requieren intervenciones paternas que permitan reubicar al padre en su rol de corresponsabilidad en la crianza. OBJETIVO: Observar el comportamiento-actitud paterna hacia el/la hijo(a) y la cantidad de oxitocina (OT) secretada en el nacimiento, en padres preparados de un modo especial para el parto. Método: Estudio piloto de 8 meses, parte de una investigación mayor cuali-cuantitativa de dos fases. La fase cualitativa inicial desarrolló una intervención preparatoria de padres para el nacimiento, con énfasis en la vinculación padre-hijo(a). La fase cuantitativa correspondió al piloto de la intervención paterna antenatal. RESULTADOS: Los padres presenciaron activamente el momento del expulsivo y el encuentro madre-hijo(a). Posteriormente, todos optaron por el contacto físico piel-piel con su hijo(a). La OT paterna experimentó un aumento (no significativo) durante el contacto padre-hijo(a) en comparación con la OT basal (momento inmediato al nacimiento). CONCLUSIONES: Padres preparados, sensibilizados y vinculados con su hijo(a) desde el embarazo experimentarían variaciones de la cantidad de OT cuando realizan contacto piel-piel con su hijo(a) en el nacimiento. Se requiere investigación experimental con una muestra mayor de participantes para concluir de manera categórica.

INTRODUCTION: Fathers have been increasingly involved in the pregnancy and birth of their children, but paternal interventions are still required to relocate the father in his role of co-responsibility in parenting. OBJECTIVE: To observe the paternal behavior-attitude towards the child and the amount of oxytocin (OT) secreted at birth in parents prepared (in a special way) for childbirth. METHOD: Pilot study of 8 months, part of a larger qualitative-quantitative research of two phases. The initial qualitative phase developed a male preparatory intervention for the birth, with emphasis on the father-child bonding. The quantitative phase corresponded to the pilot of the antenatal paternal intervention. RESULTS: Fathers actively witnessed the moment of delivery and the mother-child attachment. Subsequently, all of them opted for physical skin-to-skin contact with their child. Paternal OT experienced a (non-significant) increase during father-child contact, compared to baseline OT (immediately after birth). CONCLUSIONS: Males prepared, sensitized and involved with their child since pregnancy would experience variations in the amount of OT when they make father-child skin-to-skin contact at childbirth. Experimental research with a larger sample of participants is required to categorically reach a conclusion.

El contacto piel a piel como promotor de la lactancia materna, y su posible relación con la disminución de la hiperbilirrubinemia / Skin-to-skin contact as a promoter of breastfeeding, and its possible relationship with the reduction of hyperbilirubinemia

INTRODUCCIÓN: El contacto piel a piel (CPP) postparto es una práctica de atención de salud fuertemente aconsejada por la OMS, por los beneficios a largo y a corto plazo que conlleva tanto para la salud de la madre como para la del recién nacido. OBJETIVO: Realizar una búsqueda bibliográfica con el objetivo de determinar los beneficios que tiene la CPP durante el periodo del postparto inmediato sobre la lactancia materna (LM) y la ictericia neonatal (IN). RESULTADOS: Los resultados muestran que el CPP aumenta diversos indicadores de éxito de lactancia materna, dentro de los cuales destacan: aumento en la efectividad de la primera lactancia, mayor probabilidad de mantener la LM a 4 meses, aumento del periodo de LM en promedio, mayor probabilidad de LM exclusiva a 6 meses. No se encontraron mayores beneficios al iniciar el CPP antes de los 10 minutos, ni al prolongarlo más de 60 minutos. Además, el CPP indirectamente disminuye la probabilidad de presentar IN, debido a que aumenta la frecuencia de LM, indicador que se asocia de manera indirecta a los niveles de bilirrubina en el recién nacido. CONCLUSIÓN: La revisión de la literatura especializada nos permite concluir que el contacto temprano entre la madre y su hijo en sala de partos, piel a piel, tiene efectos significativamente positivos en la lactancia materna y puede llegar a representar un factor protector de la hiperbilirrubinemia no conjugada en el RN.

Postpartum skin-to-skin contact (SSC) is a health care practice strongly advised by the WHO because of the long- and short-term benefits for both maternal and newborn health. This update summarizes the main findings supporting the recommendation to perform SSC during the immediate postpartum period, specifically the benefits on breastfeeding (BF) and neonatal jaundice (NI). The results show that SSC increases several indicators of breastfeeding success, including: increased effectiveness of the first breastfeeding, greater probability of maintaining BF at 4 months, increased BF period on average, greater probability of exclusive BF at 6 months. No greater benefits were found when initiating SSC before 10 minutes, nor when prolonging it for more than 60 minutes. In addition, SSC indirectly decreases the probability of presenting NI, because it increases the frequency of BF, an indicator that is indirectly associated with bilirubin levels in the newborn. CONCLUSION: A review of the specialized literature allows us to conclude that postpartum skin-to-skin contact (SSC) has significantly positive effects on breastfeeding and may represent benefits in bilirubin levels in the newborn.

Avaliação in vivo da halitose e sensibilidade ao toque em pacientes que recebem prótese sobre implante / In vivo evaluation of halitosis and touch sensitivity in patients receiving implant prostheses

Com a implantodontia, muitos problemas relacionados aos tratamentos reabilitadores puderem ser solucionados. Quando um paciente perde um elemento dentário, remove-se terminações nervosas que diminuem a função táctil naquela região. A halitose é um fator comum em próteses sobre implantes, devido a maior dificuldade de higienização. O objetivo do presente estudo foi avaliar a sensibilidade e halitose de 48 pacientes (n=48), em quatro grupos distintos: Grupo 1 (próteses fixas unitárias); Grupo 2 (próteses fixas múltiplas); Grupo 3 (prótese tipo overdenture); Grupo 4 (próteses fixas do tipo protocolo). A aferição da halitose nos pacientes será por meio de um halímetro (FitScan Breath Checker ­ Tanita, Japan) e a função somatossensorial nos tecidos moles periimplantares através do teste psicofísico de sensação de toque leve (LTS) utilizando monofilamentos de von frey (Aesthesio® - Exacta). Foram realizadas as mensurações em 4 períodos distintos: no momento da colocação dos cicatrizadores (T1), 30 dias após a instalação dos cicatrizadores (T2), no momento da instalação da prótese (T3) e 30 dias após a instalação da prótese (T4). Após os dados coletados, foi realizada análise estatística e comparativa entre os grupos. Foi possível observar que a interação entre os fatores tempo, condição e tipo de prótese interferiram de forma significativa nos valores médios da sensação ao toque utilizando monofilamentos de von frey (P = 0,001). Foi possível verificar que houve associação entre o nível de halitose e o tempo de análise para o uso de prótese protocolo e para prótese overdenture. Porém, o mesmo não ocorreu para prótese unitária ou múltipla esplintada. No grupo protocolo (P = 0,002) e no grupo overdenture (P = 0,002), a contagem que apresentou achado estatisticamente significativo foi odor forte ou intenso no momento da reabertura e 30 dias após a instalação da prótese. Quanto à sensibilidade ao toque, todos os grupos obtiveram resultados significativos do aumento da sensibilidade ao toque durante e após a instalação da prótese se comparados ao inicial(AU)

With implant dentistry, many problems related to rehabilitative treatments can be solved. When a patient loses a tooth element, nerve endings that decrease tactile function in that region are removed. Halitosis is a common factor in implant prostheses, due to greater difficulty in cleaning. The aim of the present study was to evaluate the sensitivity and halitosis of 48 patients (n = 48), in four distinct groups: Group 1 (unitary fixed prostheses); Group 2 (multiple fixed prostheses); Group 3 (overdenture type prosthesis); Group 4 (fixed protocol type prostheses). The measurement of halitosis in patients will be through a Halimeter (FitScan Breath Checker - Tanita, Japan) and the so-matosensory function in peri-implant soft tissues through the psychophysical test of light touch (LTS) using von frey monofilaments (Aesthesio ® - Exact). Measurements were taken in 4 different periods: at the time of placement of the healers (T1), 30 days after the installation of the healers (T2), at the time of installation of the prosthesis (T3) and 30 days after the installation of the prosthesis (T4) . After the collected data, a statistical and comparative analysis was performed between the groups. It was possible to observe that an interaction between the factors time, condition and type of prosthesis significantly interfered in the mean values of the sensation to touch using von frey monofilaments (P = 0.001). It was possible to verify that there was an association between the level of halitosis and the analysis time for the use of protocol prosthesis and for overdenture prosthesis. However, the same did not occur for single or multiple splinted prostheses. Without group protocol (P = 0.002) and without group overdenture (P = 0.002), the count that presented a statistically significant finding was strong or intense odor at the time of reopening and 30 days after prosthesis installation. As for sensitivity to touch, all groups obtained results obtained from increased sensitivity to touch during and after installation of the prosthesis compared to the initial one(AU)

Research Progress on Touch DNA on Cartridge Cases in Forensic Field / 法医学杂志

Cartridge cases are crucial physical evidence in gun-related crimes. The successful identification of the touch DNA on cartridge cases can help to screen the suspects and reconstruct the gun-related crime scene. With the improvement of DNA extraction methods and the sensitivity of amplification kit, forensic examiners are expected to obtain more valuable information by testing the touch DNA on cartridge cases. In practical cases, the touch DNA detection on cartridge cases often encounters with low DNA content degradation, mixing and the gunshot residual interference, which brings more challenges to DNA examination and identification. This article reviews forensic research of touch DNA on the cartridge cases from the aspects of factors affecting touch DNA on cartridge cases, advances in the extraction and amplification methods, and the practical applications in order to provide reference for forensic identification of touch DNA on the cartridge cases in real cases.

Desarrollo de un procedimiento estructurado de observación clínica de la modulación táctil y desempeño de dos muestras clínicas de niños con y sin defensividad táctil / Development of an estructured procedure of clinical observations of the sensory modulation and the performance of two clinical samples of children with and without tactile defensiveness

La defensividad táctil es una de las disfunciones de integración sensorial que fueron tempranamente descritas por Jean Ayres (Lane, 2020). Sin embargo, para su diagnóstico se carece de instrumentos de evaluación basados en la observación del desempeño del niño, y en cambio, se suele utilizar casi exclusivamente el reporte de los padres por medio de cuestionarios sensoriales. Basado en diversos fundamentos teóricos se diseñó un procedimiento estructurado de observación clínica de la modulación táctil, compuesto por dos juegos con exposición a estímulos táctiles, el cual fue aplicado en contexto de práctica clínica privada, registrándose sus observaciones textualmente en fichas clínicas. El objetivo de esta investigación es describir los signos de defensividad táctil que pueden ser detectados con este procedimiento. Por medio de una pauta de análisis de 29 ítems de respuesta dicotómica, se examinaron retrospectivamente 83 fichas, de una población clínica de niños con y sin defensividad táctil, de 2 a 11 años de edad. Se comparó los resultados de una muestra de niños con defensividad táctil con otra de niños sin defensividad táctil, por medio de estadística descriptiva y pruebas no paramétricas. El desempeño de niños con defensividad táctil estadísticamente difiere de manera significativa del de niños sin defensividad táctil en el procedimiento de observación estudiado. Además, este instrumento puede contribuir con el proceso diagnóstico de defensividad táctil, por medio de la contabilización de indicadores para sugerir el diagnóstico, o de la identificación específica de algunos de ellos que serían más relevantes.

Tactile defensiveness is one of the first sensory integration dysfunctions described by Jean Ayres. However, for the diagnosis, evaluation procedures based on the observation of the child's performance are lacking, and instead, parents' reports are usually used almost exclusively. Based on several theoretical foundations, a structured procedure of clinical observations of tactile modulation was designed, consisting of two games that expose children to tactile stimuli. The observation was applied in a private clinic, using recording used for the purpose of documentation in clinical records. The objective of this research is to describe the tactile defensiveness signs that may be detected with this procedure. Through a guideline with 29 items of dichotomous response, 83 clinical records were retrospectively examined, from a clinical population of children with and without tactile defensiveness, aged 2 to 11 years. The results of a sample of children with tactile defensiveness were compared with another one of children without tactile defensiveness, through descriptive statistics and non-parametric tests. The performance of children with tactile defensiveness are significantly different from children without tactile defensiveness. In addition, this instrument can contribute to the diagnostic process of tactile defensiveness, through the analysis of indicators that suggest the diagnosis, or the specific identification of relevant signs of tactile defensiveness.

Recomendación para disminuir el riesgo de colapso súbito e inesperado posnatal / Guidance to reduce the risk of Sudden and Unexpected Postnatal Collapse

El contacto piel a piel al nacer (COPAP) entre madres y recién nacidos a término sanos es fundamental en los estándares de la Iniciativa Hospital Amigo de la Madre y el Niño de Unicef. El COPAP inmediatamente después del nacimiento favorece la estabilidad cardiorrespiratoria, la prevalencia y duración de la lactancia materna y el vínculo madre-hijo, y disminuye el estrés materno. Existe preocupación por los casos de colapso súbito inesperado posnatal durante el COPAP con el bebé en decúbito prono sobre el torso desnudo materno. Si bien es infrecuente, evoluciona en el 50 % de los casos como evento grave de aparente amenaza a la vida y la otra mitad fallece (muerte súbita e inesperada neonatal temprana). Durante el COPAP y, al menos, las primeras 2 horas después del parto, el personal de Sala de Partos y recuperación debe observar y evaluar cualquier parámetro que implique una descompensación del bebé.

Early skin-to-skin contact (SSC) between mothers and healthy term newborns is a key part of the Unicef Baby Friendly Initiative Standards. SSC immediately after birth provides cardio-respiratory stability, improves prevalence and duration of breastfeeding, improves maternal-infant bonding and decreases maternal stress. There is a concern about cases of sudden unexpected postnatal collapse during a period of SSC with the infant prone on the mother ́s chest. Said collapse includes both severe apparent life-threatening event and sudden unexpected early neonatal death in the first week of life. Even if considered rare, consequences are serious with death in half of the cases and remaining disability in majority of the cases reported. For these reasons during SSC and for at least the first 2 hours after delivery, health care personnel in the delivery and recovery room should observe and assess for any sign of decompensation in the infant

"Afectados por el tacto": sentidos atribuidos por hombres a las prácticas de prevención del cáncer de próstata / "Affected by the touch": Meanings attributed to prostate cancer prevention practices among men

RESUMEN El objetivo del estudio fue identificar y analizar los sentidos atribuidos por hombres a las prácticas relacionadas con la prevención del cáncer de próstata. Se realizó un estudio cualitativo, con entrevistas semiestructuradas, en el que participaron 21 hombres del municipio de Vitória da Conquista, Bahía. El período de recopilación de información fue entre julio y agosto de 2017. El análisis de los datos se basó en los principios de la hermenéutica-dialéctica. Se percibió que las prácticas relacionadas con la prevención del cáncer de próstata se elaboran con escasa información y permeadas por sentidos que remiten al miedo a la enfermedad, asumida como una sentencia a la vida, y a las repercusiones del tacto rectal, asimilado como una violación de la condición masculina. Se constató que las prácticas elaboradas para prevenir el cáncer de próstata reflejan las implicancias de la masculinidad en el cuidado de la salud de los hombres y, sobre todo, que la dureza masculina puede sentirse interpelada a partir de un tacto.

ABSTRACT The aim of this study was to identify and analyze meanings attributed to practices related to prostate cancer prevention among men. A qualitative methodology was employed, with semi-structured interviews being conducted with 21 men in the city of Vitoria da Conquista, Bahia, between July and August of 2017. Data analysis was based on a dialectical hermeneutic approach. We found that practices related to prostate cancer prevention were based on scarce information and permeated by a sense of fear of the disease, which was thought of as a death sentence. Additionally, these feelings were compounded by the repercussions of rectal examination, perceived as a violation of one's masculinity. We were able to observe that practices devised to prevent prostate cancer reflect the repercussions of conceptions of masculinity regarding men's health care, where manliness and toughness can be susceptible by the touch.

Short-term memory characteristics of vibro-tactile perception in human fingertips / 生理学报

This paper discusses the short-term memory of vibro-tactile perception of human fingertips. By using a self-developed vibro-tactile expression device, a recall experiment was firstly carried out among 20 subjects aged 20-30 (10 males and 10 females) to discover the memory span about the vibro-tactile perception of human fingertips. Within this memory span, a cognitive experiment analyzing the recognition accuracy and the reaction time was carried out. The results showed: (1) The vibro-tactile memory span of human fingertip is 4 ± 1; (2) The vibro-tactile memory span increases as the discrete intensity between vibration stimuli increases; (3) Too long or too short vibration duration will reduce the vibro-tactile memory span, and the optimal vibration duration for men is 400 ms, for women is 300 ms; (4) The more the number of vibration stimuli is perceived by the human fingertip, the lower the recognition accuracy and the longer the reaction time it needs; (5) Compared with the vibration stimuli in disorder, people are more likely to remember the vibration stimuli in increasing/decreasing order; (6) The information extraction mechanism of the short-term memory about fingertip vibro-tactile perception bases a point to point scanning process among these stimuli. These results help to understand the human fingertip tactile characteristics and provide a physiological basis for the study of tactile feedback technologies.

Care practices associated with breastfeeding among pregnant and lactating women / Prácticas de cuidado en mujeres gestantes y lactantes asociadas a la lactancia materna

Descriptive cross-sectional study with 417 pregnant women and 388 lactating women, belonging to a Comprehensive Care Program in Bogotá. A modular survey was applied with sociodemographic and health variables analyzed by frequency distributions, central tendency, and dispersion, with bivariate and multivariate analyses used to calculate odds ratios (OR) with 95% confidence intervals. 17% were under 18 years of age. Only 66.8% of all of the women had immediate skin-to-skin contact with their child. The risk factors for skin-to-skin contact and early initiation of breastfeeding were type of delivery (cesarean) (OR: 23.15, 95% Cl: 12.99,41.25) and (OR: 2.6, 95% Cl: 1.43, 4.73) respectively; In addition, newborn hospitalization for more than 3 days was also a risk factor for the early initiation of breastfeeding (OR: 2.85, 95% Cl: 1.42, 5.72). Not having skin-to-skin contact between the mother and her newborn was a risk factor for the early initiation of breastfeeding (OR: 2.43; Cl: 1.34; 4.41).

Estudio descriptivo transversal con 417 gestantes y 388 mujeres lactantes, perteneciente a Programa de Atención Integral en Bogotá. Encuesta modular aplicada con variables sociodemográficas y salud analizadas por distribuciones de frecuencia, tendencia central, dispersión, análisis bivariados y multivariados para calcular odds-ratios (OR) con intervalos de confianza (95%). 17% menores de 18 años. Solamente el 66.8% de todas las participantes tuvieron contacto piel a piel con sus hijos. Los factores de riesgo para el contacto piel a piel y el inicio temprano de la lactancia materna fueron el tipo de parto (cesárea) (OR: 23.15, IC95%: 12.99, 41.25) y (OR: 2.6, IC95%: 1.43, 4.73) r espectivamente; además, para el inicio temprano de la lactancia materna también fue factor de riesgo la hospitalización del recién nacido por más de 3 días (OR: 2.85, IC95%: 1.42, 5.72). No tener contacto piel a piel entre la madre y su recién nacido fue un factor de riesgo para el inicio temprano de la lactancia materna (OR: 2.43, 1C: 1.34, 4.41).

The importance of early life touch for psychosocial and moral development

One of the primary means of communicating with a baby is through touch. Nurturing physical touch promotes healthy physiological development in social mammals, including humans. Physiology influences wellbeing and psychosocial functioning. The purpose of this paper is to explore the connections among early life positive and negative touch and wellbeing and sociomoral development. In study 1, mothers of preschoolers (n = 156) reported their attitudes toward positive/negative touch and on their children's wellbeing and sociomoral outcomes, illustrating moderate to strong positive correlations between positive touch attitudes and children's sociomoral capacities and orientations and negative correlations with psychopathology. In study 2, we used an existing longitudinal dataset, with at-risk mothers (n = 682) and their children to test touch effects on moral capacities and social behaviors in early life. Results demonstrated moderate to strong relationships between positive/negative touch and concurrent child behavioral regulation and positive correlations between low corporal punishment and child sociomoral outcomes. In a third study with adults (n = 607), we found significant mediation processes connecting retrospective reports of childhood touch to adult moral orientation through attachment security, mental health, and moral capacities. In general across studies, more affectionate touch and less punishing touch were positively associated with wellbeing and development of moral capacities and engaged moral orientation. (AU)

Kir2.1 Channel Regulation of Glycinergic Transmission Selectively Contributes to Dynamic Mechanical Allodynia in a Mouse Model of Spared Nerve Injury / 神经科学通报·英文版

Neuropathic pain is a chronic debilitating symptom characterized by spontaneous pain and mechanical allodynia. It occurs in distinct forms, including brush-evoked dynamic and filament-evoked punctate mechanical allodynia. Potassium channel 2.1 (Kir2.1), which exhibits strong inward rectification, is and regulates the activity of lamina I projection neurons. However, the relationship between Kir2.1 channels and mechanical allodynia is still unclear. In this study, we first found that pretreatment with ML133, a selective Kir2.1 inhibitor, by intrathecal administration, preferentially inhibited dynamic, but not punctate, allodynia in mice with spared nerve injury (SNI). Intrathecal injection of low doses of strychnine, a glycine receptor inhibitor, selectively induced dynamic, but not punctate allodynia, not only in naïve but also in ML133-pretreated mice. In contrast, bicuculline, a GABA receptor antagonist, induced only punctate, but not dynamic, allodynia. These results indicated the involvement of glycinergic transmission in the development of dynamic allodynia. We further found that SNI significantly suppressed the frequency, but not the amplitude, of the glycinergic spontaneous inhibitory postsynaptic currents (gly-sIPSCs) in neurons on the lamina II-III border of the spinal dorsal horn, and pretreatment with ML133 prevented the SNI-induced gly-sIPSC reduction. Furthermore, 5 days after SNI, ML133, either by intrathecal administration or acute bath perfusion, and strychnine sensitively reversed the SNI-induced dynamic, but not punctate, allodynia and the gly-sIPSC reduction in lamina IIi neurons, respectively. In conclusion, our results suggest that blockade of Kir2.1 channels in the spinal dorsal horn selectively inhibits dynamic, but not punctate, mechanical allodynia by enhancing glycinergic inhibitory transmission.

La estimulación táctil/kinestésica revierte los efectos del estrés prenatal en la región CA3 del hipocampo en ratas hembras: estudio estereológico / Tactile/kinesthetic stimulation reverses the effects of prenatal stress in the CA3 region of the hippocampus in female rats: a stereological study

Esta investigación fue realizada para saber si la estimulación táctil/kinestésica postnatal es efectiva en revertir el estrés prenatal, en la citoarquitectura de CA3 del hipocampo, en crías hembras. 12 crías de ratas hembras de la cepa Sprague-Dawley, fueron distribuidas en Grupo Control (GC), Grupo con Estrés Prenatal por restricción (EP) y Grupo Estrés prenatal con Estimulación Táctil/Kinestésica postnatal (EP-ETK). El estrés prenatal en crías hembras aumentó la densidad neuronal en las áreas CA3b y CA3c (p<0,001). Cuando se compararon las crías con estrés prenatal con las que recibieron estimulación táctil/kinestésica temprana, disminuyeron las densidades neuronales en las áreas CA3b y CA3c, (p < 0,001). La estimulación táctil/kinestésica postnatal logró revertir los efectos del estrés prenatal, al reducir la densidad neuronal en las áreas CA3b y CA3c del hipocampo.

This investigation was undertaken in order to know whether the postnatal tactile/kinesthetic stimulation is effective in reversing the Prenatal Stress, in the cytoarchitecture of the CA3 region of the hippocampus, in female pups. 12 pups of female rats from the Sprague-Dawley strain were distributed to Control Group (GC), the Prenatal Maternal Stress by restriction group (EP) and Prenatal Maternal Stress with postnatal tactile/ kinesthetic stimulation Group (EP-ETK). The Prenatal Maternal Stress in female pups increased neuronal density in CA3b and CA3c areas (p<0.001). When compared to Prenatal Maternal Stress, pups prenatal stress who received early tactile/kinesthetic stimulation showed a decrease in neuronal density in CA3b and CA3c areas (p < 0,001). Postnatal tactile/kinesthetic stimulation was shown to successfully reverse the Prenatal Maternal Stress effects by decreasing neuronal density in CA3b and CA3c hippocampal areas.

Application of Touch DNA in Investigation Practice / 法医学杂志

With the continuous development of DNA extraction and testing technology, the DNA left at a crime scene plays a decisive role in the determination of criminal suspects in criminal investigation. But in the meanwhile, the anti-reconnaissance awareness of suspect is growing, which leads to a decrease of evidence left at scene during and after a crime. Therefore, in the process of evidence collection at scene, the finding and extraction of touch biological evidence, and the DNA detection are more and more important. At present, the proportion of touch evidence at the crime scene increases, which plays an increasingly important role in the detection of cases. However, with the characteristics of minute quantities, small size and secrecy, these touch evidence is difficult to be observed. What's more, various forms of pollution at the scene greatly accelerate the degradation rate of trace material, thus, the test and analysis of such material has become the emphasis and difficulty of the forensic evidence identification. This article reviews different kinds, collection and extraction methods of touch DNA, the factors that affect the detection and the problems may meet in the detection for providing an application prospect to the forensic practice.

Cortical Representation of Pain and Touch: Evidence from Combined Functional Neuroimaging and Electrophysiology in Non-human Primates / 神经科学通报·英文版

Human functional MRI studies in acute and various chronic pain conditions have revolutionized how we view pain, and have led to a new theory that complex multi-dimensional pain experience (sensory-discriminative, affective/motivational, and cognitive) is represented by concurrent activity in widely-distributed brain regions (termed a network or pain matrix). Despite these breakthrough discoveries, the specific functions proposed for these regions remain elusive, because detailed electrophysiological characterizations of these regions in the primate brain are lacking. To fill in this knowledge gap, we have studied the cortical areas around the central and lateral sulci of the non-human primate brain with combined submillimeter resolution functional imaging (optical imaging and fMRI) and intracranial electrophysiological recording. In this mini-review, I summarize and present data showing that the cortical circuitry engaged in nociceptive processing is much more complex than previously recognized. Electrophysiological evidence supports the engagement of a distinct nociceptive-processing network within SI (i.e., areas 3a, 3b, 1 and 2), SII, and other areas along the lateral sulcus. Deafferentation caused by spinal cord injury profoundly alters the relationships between fMRI and electrophysiological signals. This finding has significant implications for using fMRI to study chronic pain conditions involving deafferentation in humans.

Expresiones de apego en madres de recién nacidos prematuros de 28 a 32 semanas dentro de los 7días de internación en Unidad de Cuidados Intensivos Neonatales, del Hospital Materno Neonatal "Eloísa Torrent de Vidal" Corrientes Capital año 2016 / Expresiones de apego en madres de recién nacidos prematuros de 28 a 32 semanas dentro de los 7 días de internación en Unidad de Cuidados Intensivos Neonatales, del Hospital Materno Neonatal "Eloísa Torrent de Vidal" Corrientes Capital año 2016

El vínculo madre-hijo se comienza a generar desde la concepción, desarrollándose a través de toda la gestación y el apego es un tipo de vinculación estrecha que caracteriza a una relación muy sensible entre la madre y el recién nacido. El objetivo de este trabajo fue describir y caracterizar las expresiones de apego de las madres de recién nacido prematuros de 28 a 32 semanas internados en el Hospital Materno Neonatal Eloísa Torrent de Vidal. Se realizó un estudio cuantitativo, descriptivo, prospectivo, transversal, se trabajó con 20 madres de recién nacidos prematuros dentro de los 7 días internación. Los resultados obtenidos con respecto a la variable edad se pudo observar un mínimo de 16 años, un máximo de 37 años. Con respecto a la variable contacto piel a piel, 60% refirió que no la dejan alzar al niño por la complejidad, 20% tiene miedo a alzarlo ya que en algunos casos su niño es muy pequeño, 15% podía alzarlo sin inconveniente, y 5% manifestó no querer alzarlo. Los resultados obtenidos en el análisis de la variable comunicación arrojó que el 65% de las madres le habla a su niño durante la visita y solo un 5% permanece callada. La realización de este estudio de investigación puso en evidencia que las madres tienen expresiones de apego frente a su recién nacido internado en la Unidad de Cuidados Intensivos Neonatales sobre todo aquellos vinculados a la espera de lo verbal. Como factor negativo en esta diada madre niño se observó la dificultad de alzarlo por su complejidad.

Summary The mother-child bond begins to generate from conception, developing through all gestation and attachment is a type of close bond that characterizes a very sensitive relationship between the mother and the newborn. The aim of this study was to describe and characterize the attachment expressions of mothers of preterm infants from 28 to 32 weeks admitted to the Hospital Materno Neonatal Eloísa Torrent de Vidal. A quantitative, descriptive, prospective, cross - sectional study was performed with 20 mothers of preterm infants within 7 days of admission. The results obtained with respect to the variable age could be observed a minimum of 16 years, a maximum of 37 years. Regarding the variable skin-to-skin contact, 60% stated that they did not let the child lift because of the complexity, 20% were afraid to raise it because in some cases their child was very small, 15% could lift it without inconvenience, and 5 % Said he did not want to raise it. The results obtained in the analysis of the communication variable show that 65% of the mothers speak to their child during the visit and only 5% remain silent. The realization of this research study showed that mothers have expressions of attachment to their newborn interned in the Unit of Neonatal Intensive Care, especially those linked to the expectation of verbal. As a negative factor in this mother-child dyad it was observed the difficulty of raising it by its complexity. This situation was also linked to limitations in touch and caresses, complementary elements for the generation of reciprocal and affective attachment.

Resumo O vínculo mãe-filho começa a gerar, desde a concepção, o desenvolvimento ao longo da gravidez e do apego é um tipo de relação estreita que caracteriza uma relação muito sensível entre a mãe eo recém-nascido.O objetivo deste estudo foi descrever e caracterizar as expressões de ligação de mães de recém-nascidos prematuros 28 a 32 semanas internados na Neonatal Maternal Hospital Heloise Torrent de Vidal. um descritivo prospectivo estudo quantitativo,,, transversal, trabalhamos com 20 mães de recém-nascidos prematuros no prazo de 7 dias de hospitalização. Os resultados obtidos no que diz respeito à idade variável foi observado um mínimo de 16 anos, um máximo de 37 anos. No que diz respeito ao contato variando pele a pele, 60% disse que não vai deixá-la criar o filho pela complexidade, 20% têm medo de segurá-lo porque em alguns casos a criança era muito pequeno, 15% poderia levantá-la sem inconvenientes, e 5 %, ele disse não querer segurá-lo. Os resultados obtidos na análise da variável destemor comunicação do que 65% das mães fala para o seu filho durante a visita e apenas 5% permanece em silêncio. A realização deste estudo revelaram que as mães têm expressões de ligação contra o recém-nascido internado em Unidade de Terapia Intensiva Neonatal especialmente aqueles ligados a aguardar a verbal. Como fator negativo neste mãe díade criança foi observada a dificuldade de segurá-lo pela sua complexidade. Esta situação a limitações no toque e carícias, elementos complementares para a geração de apego recíproco e emocional também estava ligada.

Evaluation of Direct Rapid Immunohistochemical test (DRIT) of Canis lupus familiaris hippocampal touch impression smears using a monospecific polyclonal antibody for rabies virus detection

@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Rabies is an important zoonotic disease that needs to be eradicated worldwide. It is still prevalent in the Philippines, thus development of a relatively affordable but still accurate and rapid post-mortem detection test for the virus is desired, especially in regional laboratories.<br /><strong>METHODS:</strong>The study evaluated the Direct Rapid Immunohistochemical Testing (DRIT) of hippocampal touch impressions of suspected rabid Canis lupus familiaris using monospecific N protein polyclonal antibody developed by the Research Institute for Tropical Medicine (RITM). One hundred sixty (160) acetone-fixed hippocampal touch impressions were subjected DRIT.<br /><strong>RESULTS:</strong> One hundred thirteen (70.6%) out of 160 samples tested positive for rabies viral antigen (RVA) and 47 (29.4%) out of 160 samples tested negative for RVA. No false positive and false negative results were obtained. The results agree with the gold standard, dFAT.<br /><strong>CONCLUSION:</strong> DRIT was able to detect low to high concentrations of RVA in the hippocampal touch impressions based on the grading distribution. DRIT had 100% sensitivity, specificity and over-all accuracy using monospecific polyclonal antibodies, which suggests its use as a more affordable alternative to the gold standard dFAT.</p>

Effect of elastic strain rate ratio method and virtual touch tissue quantification on the diagnosis of breast masses / 中南大学学报(医学版)

OBJECTIVE@#To determine the effect of elastic strain rate ratio method and virtual touch tissue quantification (VTQ) on the diagnosis of breast masses.
@*METHODS@#Sixty female patients with breast cancer, who received surgical treatment in Daqing Oilfield General Hospital, were enrolled. All patients signed the informed consent paperwork and they were treated by routine ultrasound examination, compression elastography (CE) examination, and VTQ examination in turn. Strain ratio (SR) was checked by CE and shear wave velocity (SWV) value was measured by VTQ. The diagnostic values of different methods were evaluated by receiver operating characteristic (ROC) curves in the diagnosis of benign and malignant breast tumors.
@*RESULTS@#The maximum diameter and SWV value of the benign tumors were lower than those of the malignant tumors, and the SR ratio of benign masses was higher than that of malignant tumors (P<0.01). The AUC, sensitivity and specificity for elastic strain rate and VTQ for single or combined use were higher than those of conventional ultrasound (0.904, 97.5%, 69.2%; 0.946, 87.5%, 87.2%; 0.976, 90%, 97.4% vs 0.783, 85%, 61.5%). The AUC and specificity of VTQ were higher than those of the elastic strain rate (0.946, 87.2% vs 0.904, 69.2%), but the sensitivity of VTQ was higher than that of the latter (87.5% vs 97.5%). The AUC and specificity for combination of both methods were higher than those of single method, but the sensitivity was lower than that of the elastic strain rate. 
@*CONCLUSION@#Combination of elastic strain rate ratio method with VTQ possesses the best diagnostic value and the highest diagnostic accuracy in the diagnosis of breast mass than that used alone.
