Factors associated with engagement in a police-advocacy home-visit intervention to prevent domestic violence

This study examines factors related to engagement in the services offered by police officer-advocate teams on the basis of police and clinical records for 301 female victims referred to the Domestic Violence Home Visit Intervention (DVHVI) program. The authors find that the severity of intimate partner violence charges and ethnicity of the victim, advocate, and police officer are all significantly related to engagement in the DVHVI, with Hispanic women served by Hispanic advocate-officer teams more engaged in services than African American or Caucasian women. The data suggest that this intervention model may be particularly beneficial for Hispanic victims of intimate partner violence when implemented by a Spanish-speaking officer-advocate team.     

THE HYPOPHYSEAL SUBSTANCE GIVING INCREASED GONADOTROPIC EFFECTS WHEN COMBINED WITH PROLAN

The increased gonadotropic effect obtained by combining prolan with hypophyseal extracts can be secured equally well by the use of preparations which contain high amounts of the growth or of the gonad-stimulating hormone. In hypophyseal extracts containing the growth hormone, the synergistic effects do not parallel the content of growth-promoting substance. Similarly, in hypophyseal extracts containing the gonad-stimulating hormone, the synergistic effects do not parallel the content in the gonadotropic factor. The hypophyseal substance involved has been prepared sufficiently free of the growth and gonad-stimulating hormones to make it inadmissible to consider either of these substances as responsible for the reaction.     

Transplanted human cones incorporate into the retina and function in a murine cone degeneration model

Once human photoreceptors die, they do not regenerate, thus, photoreceptor transplantation has emerged as a potential treatment approach for blinding diseases. Improvements in transplant organization, donor cell maturation, and synaptic connectivity to the host will be critical in advancing this technology for use in clinical practice. Unlike the unstructured grafts of prior cell-suspension transplantations into end-stage degeneration models, we describe the extensive incorporation of induced pluripotent stem cell (iPSC) retinal organoid–derived human photoreceptors into mice with cone dysfunction. This incorporative phenotype was validated in both cone-only as well as pan-photoreceptor transplantations. Rather than forming a glial barrier, Müller cells extended throughout the graft, even forming a series of adherens junctions between mouse and human cells, reminiscent of an outer limiting membrane. Donor-host interaction appeared to promote polarization as well as the development of morphological features critical for light detection, namely the formation of inner and well-stacked outer segments oriented toward the retinal pigment epithelium. Putative synapse formation and graft function were evident at both structural and electrophysiological levels. Overall, these results show that human photoreceptors interacted readily with a partially degenerated retina. Moreover, incorporation into the host retina appeared to be beneficial to graft maturation, polarization, and function.     

Vitamin D Status among Women in a Rural District of Nepal: Determinants and Association with Metabolic Profile—A Population-Based Study

Hypovitaminosis D is prevalent worldwide, and especially in South-Asia. According to the Institute of Medicine (IOM), 25(OH)D levels below 30 nmol/L are defined as vitamin D deficiency (VDD) and levels between 30–50 nmol/L as insufficiency (VDI). Besides its role in calcium homeostasis, it has been postulated that vitamin D is involved in metabolic syndrome. Given the scarcity of data on vitamin D status in Nepal, we aimed to examine the prevalence of VDD and VDI, as well as the determinants and association with metabolic parameters (lipids, HbA1c), in a cohort of women in rural Nepal. Altogether, 733 women 48.5 ± 11.7 years of age were included. VDD and VDI were observed in 6.3 and 42.4% of the participants, respectively, and the prevalence increased by age. Women reporting intake of milk and eggs > 2 times weekly had higher 25(OH)D levels than those reporting intake < 2 times weekly. Women with vitamin D levels < 50 nmol/L displayed higher levels of cholesterol, LDL-cholesterol, triglycerides, and HbA1c. Additionally, a regression analysis showed a significant association between hypovitaminosis D, dyslipidemia, and HbA1c elevation. In conclusion, VDI was prevalent and increased with age. Milk and egg intake > 2 times weekly seemed to decrease the risk of VDI. Moreover, hypovitaminosis D was associated with an adverse metabolic profile.     

The Role of Social Support in Machismo and Acceptance of Violence Among Adolescents in Europe: Lights4Violence Baseline Results

PurposeTo analyze the potential association between social support, experiences of violence, and sociodemographic characteristics of adolescents and the likelihood of acceptance of violence and machismo in different European countries.MethodsCross-sectional design. We recruited 1,555 participants ages 13–16 from secondary schools in Alicante (Spain), Rome (Italy), Iasi (Romania), Matosinhos (Portugal), Poznan (Poland), and Cardiff (UK). We used linear regression models to identify how social support from teachers and parents, experiences of violence—dating violence, bullying, cyberbullying, abuse in childhood—and sociodemographic characteristics were associated with violent thinking, specifically: machismo and acceptance of violence. The analysis was stratified by sex.ResultsAcceptance of violence was higher for those who had lower perceived social support from parents (β_girls = ?154, p < .001; β_boys = ?.114, p = .019) for both sexes. Perpetration of bullying and/or cyberbullying was associated with higher scores for machismo and acceptance of violence for both sexes (β_girls = .067, p = .035; β_boys = .225, p < .001; (β_girls = .118, p < .001; β_boys = .210, p < .001). Being the victim of dating violence, having suffered physical and/or sexual abuse in childhood, and lower perceived social support from teachers were associated with higher scores for both machismo and acceptance of violence. These associations differed between girls and boys.ConclusionsMachismo and acceptance of violence are widely present amongst adolescents in different European countries. Our results suggest the importance of providing educational/psycho-educational interventions with boys and girls to prevent these attitudes and, in turn, prevent interpersonal violence, including bullying and dating violence.     

Neural processing associated with cognitive empathy in pedophilia and child sexual offending

Behavioral studies found evidence for superior cognitive empathy (CE) in pedophilic men without a history of child sexual offending (P − CSO) compared to pedophilic men with a history of child sexual offending (P + CSO). Functional magnetic resonance imaging (fMRI) studies also point to differences between P − CSO and P + CSO. Neural processing associated with CE has not yet been investigated. Therefore, the present study aimed to explore the neural correlates of CE in subjects with pedophilia with (P + CSO) and without (P − CSO) child sexual offending. 15 P + CSO, 15 P − CSO and 24 teleiophilic male controls (TC) performed a CE task during fMRI. We observed reduced activation in the left precuneus (Pcu) and increased activation in the left anterior cingulate cortex (ACC) in P − CSO compared to P + CSO. P − CSO also showed stronger connectivity between these regions, which might reflect a top-down modulation of the Pcu by the ACC toward an increased self-focused emotional reaction in social situations. There was also evidence for increased right superior temporal gyrus activation in P − CSO that might constitute a potentially compensatory recruitment due to the dampened Pcu activation. These findings provide first evidence for altered neural processing of CE in P − CSO and underline the importance of addressing CE in pedophilia and CSO in order to uncover processes relevant to effective prevention of child sexual abuse.     

Material differentiation by dual energy CT: initial experience

The aim of this study was to assess the feasibility of a differentiation of iodine from other materials and of different body tissues using dual energy CT. Ten patients were scanned on a SOMATOM Definition Dual Source CT (DSCT; Siemens, Forchheim, Germany) system in dual energy mode at tube voltages of 140 and 80 kVp and a ratio of 1:3 between tube currents. Weighted CT Dose Index ranged between 7 and 8 mGy, remaining markedly below reference dose values for the respective body regions. Image post-processing with three-material decomposition was applied to differentiate iodine or collagen from other tissue. The results showed that a differentiation and depiction of contrast material distribution is possible in the brain, the lung, the liver and the kidneys with or without the underlying tissue of the organ. In angiographies, bone structures can be removed from the dataset to ease the evaluation of the vessels. The differentiation of collagen makes it possible to depict tendons and ligaments. Dual energy CT offers a more specific tissue characterization in CT and can improve the assessment of vascular disease. Further studies are required to draw conclusions on the diagnostic value of the individual applications.     

Magnesium-to-Calcium Ratio and Mortality from COVID-19

Obesity, type 2 diabetes, arterial hypertension, decrease in immune response, cytokine storm, endothelial dysfunction, and arrhythmias, which are frequent in COVID-19 patients, are associated with hypomagnesemia. Given that cellular influx and efflux of magnesium and calcium involve the same transporters, we aimed to evaluate the association of serum magnesium-to-calcium ratio with mortality from severe COVID-19. The clinical and laboratory data of 1064 patients, aged 60.3 ± 15.7 years, and hospitalized by COVID-19 from March 2020 to July 2021 were analyzed. The data of 554 (52%) patients discharged per death were compared with the data of 510 (48%) patients discharged per recovery. The ROC curve showed that the best cut-off point of the magnesium-to-calcium ratio for identifying individuals at high risk of mortality from COVID-19 was 0.20. The sensitivity and specificity were 83% and 24%. The adjusted multivariate regression model showed that the odds ratio between the magnesium-to-calcium ratio ≤0.20 and discharge per death from COVID-19 was 6.93 (_95%CI 1.6–29.1) in the whole population, 4.93 (_95%CI 1.4–19.1, p = 0.003) in men, and 3.93 (_95%CI 1.6–9.3) in women. In conclusion, our results show that a magnesium-to-calcium ratio ≤0.20 is strongly associated with mortality in patients with severe COVID-19.     

Vivencias y percepción de los profesionales sanitarios de las urgencias extrahospitalarias ante las agresiones

ObjetivoConocer las opiniones de los profesionales sanitarios que trabajan en el Punto de Atención Continuada de Ourense (PAC) con relación a las agresiones laborales.DiseñoEstudio cualitativo con enfoque fenomenológico realizado entre enero y mayo del 2019.EmplazamientoPAC.ParticipantesVeinte profesionales de distintas categorías.MédodoMuestreo estructural. Se emplearon entrevistas abiertas grabadas en audio, previo consentimiento de los participantes.ResultadosLos profesionales entrevistados manifiestas haber sido víctimas de agresiones, sobre todo verbales. Estas agresiones según los participantes son tan habituales que las han normalizado dentro de su jornada laboral. Ninguno ha denunciado nunca este tipo de conductas, en gran medida porque consideran que la burocracia y los trámites administrativos son tediosos, y otros por desconocimiento del procedimiento. Este tipo de situaciones, a nivel laboral, les causa sentimientos de tristeza, rabia e impotencia y son la causa, según ellos, del aumento de la medicina defensiva. Los profesionales consideran que la causa del aumento de las agresiones entre el colectivo es la mala educación y la gestión inadecuada del empoderamiento del paciente.ConclusionesLos profesionales sanitarios sufren continuamente agresiones, sobre todo de tipo verbal, siendo algo habitual en su día a día. Estas agresiones no son denunciadas, pero les causan múltiples sentimientos negativos y disruptivos, llegando a modificar su manera de trabajar.Palabras clave: Violencia laboral, Personal de salud, Agresión, Violencia
