Virtually Delivered Psychosocial Intervention for Prenatally Diagnosed Congenital Heart Disease: Feasibility and Acceptability of HEARTPrep.

Prenatal diagnosis of congenital heart disease (CHD) often leads to anxiety, depression, and traumatic stress in expectant mothers, with long-term implications for the child and family. However, psychosocial intervention is rarely incorporated into prenatal care. HEARTPrep is a virtually delivered psychosocial intervention aimed at reducing distress and social isolation and increasing parenting self-efficacy and hope for mothers expecting a baby with CHD to promote long-term child/family well-being. This study evaluated the feasibility and acceptability of HEARTPrep. Participants were mothers receiving cardiology care for a fetal CHD diagnosis. Partners could participate with the mother. HEARTPrep was delivered through a mobile app and telehealth. Feasibility was assessed through enrollment/retention rates. Acceptability was assessed through 20 Likert-scale and five open-ended questions. Of 39 recruited mothers, 35 (90%) enrolled. Half of partners (48%) also participated. Twenty-seven of 35 enrolled mothers (77%) completed HEARTPrep. On a scale from 0 (Not at All) to 4 (Very), mean item acceptability scores ranged from 3.5 to 3.9. Mothers reported HEARTPrep helped them feel less distressed (mean: 3.74), less alone (3.84), more prepared (3.89), and more hopeful (3.84). Opportunities to process emotions, develop coping skills, learn with their partner, navigate relationships, understand they are not alone, connect with peer support, access resources, and prepare for stressors were described as helpful. HEARTPrep is feasible and acceptable for mothers expecting a baby with CHD. Future research will evaluate its efficacy in preventing/reducing maternal mental health problems and improving postnatal clinical outcomes.

Do mothers and fathers agree? Examining interparental ratings of youth externalizing behaviors among ethnically diverse families.

OBJECTIVE: This study examined the association between youth, parent, and family characteristics in mother-father agreement of youth externalizing behaviors among ethnically diverse families. METHOD: Eighty-eight mother-father dyads of youth (44% Latino, 38% European-American, 17% African American) 6-16 years participated. RESULTS: Overall associations between parent's reports of youth behavior problems were positively correlated. Significant predictors of parent difference scores in regression analyses included mother's depression scores (negatively), mother and father parenting stress scores (positively and negatively, respectively), and child's symptom severity (positively in the Inattention and Learning Problems models; negatively in the Defiance/Aggression model). CONCLUSIONS: Results highlight the need for psychosocial screening of youth's parents during child psychological assessment to identify situations in which both parent reports are needed for youth assessment. Further, it contributes to the small literature base of discrepancies in parent reports in minority youth and expands upon the minimal research involving paternal caregivers.

Bactericidal effect of bovine lactoferrin and synthetic peptide lactoferrin chimera in Streptococcus pneumoniae and the decrease in luxS gene expression by lactoferrin.

Streptococcus pneumoniae (pneumococcus) is responsible for nearly one million child deaths annually. Pneumococcus causes infections such as pneumonia, otitis media, meningitis, and sepsis. The human immune system includes antibacterial peptides and proteins such as lactoferrin (LF), but its activity against pneumococcus is not fully understood. The aim of this work was to evaluate the bactericidal effect of bovine lactoferrin (bLF) and the synthetic LF-peptides lactoferricin (LFcin17-30), lactoferrampin (LFampin265-284), and LFchimera against S. pneumoniae planktonic cells. The mechanism of damage was also investigated, as well as the impact of these peptides on the transcription levels of genes known to encode important virulence factors. S. pneumoniae planktonic cells were treated with bLF, LFcin17-30, LFampin265-284 and LFchimera at different time points. The viability of treated planktonic cells was assessed by dilution and plating (in CFU/ml). The interaction between LF and LF-peptides coupled to fluorescein was visualized using a confocal microscope and flow cytometry, whereas the damage at structural levels was observed by electron microscopy. Damage to bacterial membranes was further evaluated by membrane permeabilization by use of propidium iodide and flow cytometry, and finally, the expression of pneumococcal genes was evaluated by qRT-PCR. bLF and LFchimera were the best bactericidal agents. bLF and peptides interacted with bacteria causing changes in the shape and size of the cell and membrane permeabilization. Moreover, the luxS gene was down-regulated in bacteria treated with LF. In conclusion, LF and LFchimera have a bactericidal effect, and LF down-regulates genes involved in the pathogenicity of pneumococcus, thus demonstrating potential as new agents for the treatment of pneumococcal infections.

[Kawasaki disease and multisystem inflammatory syndrome in children. Differences, and similarities in a pediatric center in Mexico]. / Enfermedad de Kawasaki y síndrome inflamatorio multisistémico en niños. Diferencias y similitudes en un centro pediátrico de México.

OBJECTIVE: To evaluate the differences and similarities in clinical picture, laboratory findings and outcomes between children's with Kawasaki Disease (KD) versus multisystem inflammatory syndrome (MIS-C). METHODS: We conducted a retrospective, comparative study from children with Kawasaki Disease (KD) hospi-talized in Sinaloa Pediatric Hospital from January 1, 2004, to March 31, 2020, and patients with multisystem inflammatory syndrome (MIS-C) according with World Health Organization (WHO) case definition criteria be-tween May 1, 2020 and May 31, 2021. Demographic characteristics, epidemiological data, clinical features, laboratory findings, type of treatment and clinical outcomes were compared among both groups. RESULTS: Eighty-one patients were included (62 patients with KD and 19 with MIS-C). several clinical and lab-oratory differences were found among these two entities. Median age was lower in KD vs. MIS-C (25 vs 79 months). Those finding more frequent in KD were male gender (64.5 vs. 47.4%), Mucocutaneous features (93.5 vs. 63.2%): Oral changes (83.9 vs. 63.2%) and extremity changes (77.4 vs. 57.9%); complete form of KD was (75.8 vs. 47.4%), Coronary artery aneurysm (16.1 vs. 11.8%). Secondly, findings that were more frequent in MIS-C than KD were Gastrointestinal involvement (89.4 vs. 9.6%), shock (57.9 vs. 3.2%), neurological symp-toms (63.1 vs. 11.2%), kidney involvement (52.6 vs. 16.1%), heart disease in general (52.9% vs 29%): Myocardial dysfunction (23.5 vs. 11.3%) and pericardial effusion (17.6 vs. 2.9%). Lymphocyte count (2.07 + 2.03 vs. 4.28 + 3.01/mm3), platelet count (197.89 + 187.51 vs. 420.37 + 200.08/mm3); serum albumin (2.29 + 0.65 vs. 3.33 + 0.06g/dL), and CPR (21.4 + 11.23 vs. 14.26 + 12.37 mg/dL). KD vs. MIS-C types of Treatment: IVIG (96.8 vs. 94.7%), systemic steroids (4.82 vs. 94.7%), IVIG resistance (19.4 vs. 15.8). Finally, mortality in KD was 0% and 5.3% in MIS-C. CONCLUSIONS: Similarities were found in both groups such as fever, rash, and conjunctivitis. Nevertheless, signifi-cant differences such as severity of clinical presentation with multi-organ involvement and worst inflammato-ry response were found more frequently in MIS-C group than KD group, requiring more fluid replacement, use of inotropic agents and higher steroids dosages. Also, mortality rate was higher in patients with MIS-C thanpatients with KD. Similar results have been observed in other studies where both disorders were compared.

La mayoría de los pacientes con enfermedad de Kawasaki fueron hombres (64.5 vs 47.4%), con características mucocutáneas (93.5 vs 63.2%): cambios orales (83.9 vs 63.2%) y cambios en las extremidades (77.4 vs 57.9%); la forma completa de enfermedad de Kawasaki fue 75.8 vs 47.4%, concomitante con aneuris-ma de la arteria coronaria (16.1 vs 11.8%). Los hallazgos más frecuentes en sujetos con síndrome inflamatorio multisistémico fueron: afectación gastrointestinal (89.4 vs 9.6 %), choque (57.9 vs 3.2%), síntomas neurológicos (63.1 vs 11.2%), afectación renal (52.6 vs 16.1%) y cardiopatías en general (52.9 vs 29%): disfunción miocárdica (23.5 vs 11.3%) y derrame pericárdico (17.6 vs 2.9%). La concentración media de linfocitos fue: 2.07 + 2.03 vs4.28 + 3.01/mm3), plaquetas (197.89 + 187.51 vs 420.37 + 200.08/mm3); albúmina sérica (2.29 + 0.65 vs 3.33 + 0.06 g/dL) y PCR (21.4 + 11.23 vs 14.26 + 12.37 mg/dL). Los tratamientos en enfermedad de Kawasaki vssíndrome inflamatorio multisistémico: IVIG (96.8 vs 94.7%), corticosteroides sistémicos (4.82 vs 94.7%), resis-tencia a IVIG (19.4 vs 15.8). La mortalidad fue de 0 vs 5.3%. CONCLUSIONES: Se encontraron similitudes en cuanto a síntomas en ambos grupos (fiebre, exantema y conjun-tivitis); no obstante, hubo diferencias significativas respecto de las manifestaciones clínicas, con afección multiorgánico y peor respuesta inflamatoria en pacientes con síndrome inflamatorio multisistémico, incluso mayor requerimiento de reposición de líquidos, administración de agentes inotrópicos, dosis más altas de corticosteroides, y elevada tasa de mortalidad. Estos resultados se han observado en otros estudios, donde se compararon ambos trastornos.

Initiation of and barriers to prenatal care use among low-income women in San Antonio, Texas.

Healthy People 2010 goals set a target of 90% of mothers starting prenatal care in the first trimester of pregnancy. While there are questions about the value of prenatal care (PNC), there is much observational evidence of the benefits of PNC including reduction in maternal, fetal, perinatal, and infant deaths. The objective of this study was to understand barriers to PNC as well as factors that impact early initiation of care among low-income women in San Antonio, Texas. A survey study was conducted among low-income women seeking care at selected public health clinics in San Antonio. Interviews were conducted with 444 women. Study results show that women with social barriers, those who were less educated, who were living alone (i.e. without an adult partner or spouse), or who had not planned their pregnancies were more likely to initiate PNC late in their pregnancies. It was also observed that women who enrolled in the WIC program were more likely to initiate PNC early in their pregnancies. Women who initiated PNC late in pregnancy had the highest odds of reporting service-related barriers to receiving care. However, financial and personal barriers created no significant obstacles to women initiating PNC. The majority of women in this study reported that they were aware of the importance of PNC, knew where to go for care during pregnancy, and were able to pay for care through financial assistance, yet some did not initiate early prenatal care. This clearly establishes that the decision making process regarding PNC is complex. It is important that programs consider the complexity of the decision-making process and the priorities women set during pregnancy in planning interventions, particularly those that target low-income women. This could increase the likelihood that these women will seek PNC early in their pregnancies.

Development of Sorbent Materials based on Polymer Waste and their Compounds with Nanomaterials for Oil Spill Remediation.

AIMS: The purpose of this work was to obtain a hydrophobic sorbent material with potential applications in oil spill remediation. BACKGROUND: The accidents due to oil spills cause long-term ecological damage, especially in the aquatic environment. The cleaning of oil spills can be carried out by many methods and techniques, being absorbents the most attractive due to the possibility of recovery and complete elimination of the hydrocarbons in situ from the water surface. In recent years, interest in polymeric materials for oil spill remediation has increased due to its low cost, high stability, and recyclability. OBJECTIVE: The objective of this work was the development of sorbent materials based on polymer wastes, such as Polyethylene Terephthalate (PET), obtained from recycled bottles, and recycled Polyurethane (PU), for its application in the recovery of oil spills. METHODS: Sorbent materials were prepared from polymer wastes, using salt molds for the formation of porous materials with a composition of PU of 5, 10 and 15%, which were subsequently hydrophobized using carbon nanotubes or silica nanoparticles by dip-coating technique. RESULTS AND DISCUSSION: The obtained hydrophobic sorbent materials were characterized by Scanning Electron Microscopy (SEM) and Infrared Spectroscopy (FTIR). The resulting absorbent has shown capacity to separate oil from water; the best result was obtained by the sponge of PET-PU (10% PU) hydrophobized with a suspension with low multi-wall carbon nanotubes (MWCNTs) concentration, obtaining an absorption capacity of 2.01 g/g. CONCLUSION: Besides the standard sorption capacity, these cheap sorbent materials had interesting properties like low density, high hydrophobicity and buoyancy, which could be applied in other applications related to solving oil spills.

Aspectos jurídicos da jornada de trabalho em enfermagem: reflexão teórica / Legal aspects of work shift in nursing: theoretical reflection

Objetivo: perquirir acerca da regulamentação das relações de trabalho na enfermagem e refletir sobre os aspectos jurídicos de sua jornada de trabalho. Metodologia: trata-se de um estudo reflexivo, que analisou as relações de trabalho da equipe de enfermagem com foco em sua jornada de trabalho, com um olhar direcionado aos aspectos jurídicos que envolvem a temática. Resultados: a equipe de enfermagem não dispõe de proteção legal específica acerca de sua jornada de trabalho, apesar de desenvolver um trabalho essencial à vida e de estar presente na quase totalidade das instituições de saúde. A população tem direito de ser atendida por profissionais competentes e saudáveis, tendo em vista que a assistência segura e de qualidade, além de moralmente requerida, é mais econômica, pois evita danos e reduz ações judiciais contra os serviços de saúde. Para tanto surge a discussão sobre o Projeto de Lei 2.295/2000, que defende carga horária de 30 horas semanais, refletindo uma conquista histórica da classe de enfermagem, que se fundamenta em aspectos biológicos, sociais e econômicos. Conclusão: a redução da jornada de trabalho permite a prestação de uma assistência mais segura e representa nada mais que a concretização do arcabouço jurídico protecionista vigente.

Objective: to assert concerning the regulation of labor relations in nursing and to reflect on the legal aspects of working in nursing. Methodology: this is a reflective study that examined the working relationships of the nursing staff to focus on its workday with targeted legal aspects involving the theme. Results: the nursing staff has no specific legal protection about its workday, while developing essential work to life and to be present in almost all health institutions. The population is entitled to be served by healthy and competent professionals, in order that safe and quality care, and morally required, it is more economical because it prevents damage and reduces lawsuits against health services. For this discussion on the Draft Law 2295 /2000, which advocates a workload of 30 hours per week, reflecting a historic conquest of the nursing class, which it is based on biological, social and economic aspects. Conclusion: the reduction in working hours allows the provision of a safer care and represents nothing more than the realization of the current protectionist legal framework.

Increased viral replication in simian immunodeficiency virus/simian-HIV-infected macaques with self-administering model of chronic alcohol consumption.

Alcohol abuse constitutes a major cohort among HIV-infected individuals. The precise effect of alcohol addiction on HIV pathogenesis remains inconclusive, however. This study was designed to determine the effect of alcohol dependence on virus replication and CD4 profiles in simian immunodeficiency virus/simian-HIV-infected rhesus macaques. A group of 3 male Indian rhesus macaques was adapted to a self-drinking model of alcohol consumption, whereas another group of 3 macaques was provided a Nutrasweet solution. After 7 weeks of alcohol consumption, the alcohol-dependent animals along with controls were intravenously inoculated with a mixture of SHIV(KU), SHIV(89.6)P, and SIV/17E-Fr. These animals were followed for a period of 24 weeks for complete blood cell counts, CD4 cell profiles, and viral loads in the blood and cerebral compartments. The alcohol and control groups showed comparable peak viral loads in the blood. The plasma viral load in the alcohol group was 31- to 85-fold higher than that in the control group at weeks 18 through 24 after infection, however. The pattern of cerebrospinal fluid viral replication was also comparable during the acute phase; however, the virus continued to replicate in the brain of alcohol-dependent animals, whereas it became undetectable in the controls. The extent of CD4 cell loss in the alcohol group was significantly higher than that in the control animals at week 1 after infection.

Modulation by morphine of viral set point in rhesus macaques infected with simian immunodeficiency virus and simian-human immunodeficiency virus.

Six rhesus macaques were adapted to morphine dependence by injecting three doses of morphine (5 mg/kg of body weight) for a total of 20 weeks. These animals along with six control macaques were infected intravenously with mixture of simian-human immunodeficiency virus KU-1B (SHIV(KU-1B)), SHIV(89.6P), and simian immunodeficiency virus 17E-Fr. Levels of circulating CD4(+) T cells and viral loads in the plasma and the cerebrospinal fluid were monitored in these macaques for a period of 12 weeks. Both morphine and control groups showed precipitous loss of CD4(+) T cells. However this loss was more prominent in the morphine group at week 2 (P = 0.04). Again both morphine and control groups showed comparable peak plasma viral load at week 2, but the viral set points were higher in the morphine group than that in the control group. Likewise, the extent of virus replication in the cerebral compartment was more pronounced in the morphine group. These results provide a definitive evidence for a positive correlation between morphine and levels of viral replication.
