RESUMO
Staphylococcus aureus (S. aureus) is a kind of gram-positive bacteria, and its virulence factors can cause many kinds of infections. Traditional antibiotics can not only kill bacteria, but also easily lead to bacterial resistance. Jingfang Mixture (JFM) is commonly used in clinic to prevent and treat epidemic diseases and infectious diseases. The main purpose of this study is to explore the inhibitory effect of JFM on alpha-hemolysin (Hla) of S. aureus and to alleviate the damage caused by Hla. We found that JFM could inhibit the hemolytic activity, gene and protein level and neutralizing activity of Hla in a dose-dependent manner at the concentrations of 125, 250 and 500 µg/mL, without affecting the growth of bacteria. In addition, JFM reduced the damage of Hla to A549 cells and the release of lactate dehydrogenase (LDH). We also observed that in the S. aureus - induced pneumonia mouse model, JFM could significantly prolong the life of mice, reduce the bacterial load in the lungs, significantly improve the pathological state of the lungs and alleviate the damage caused by inflammatory factors, and the pathogenicity of gene deletion strain DU 1090 of S. aureus to pneumonia mice was also significantly reduced. In conclusion, this study proved that JFM is a potential drug against S. aureus infection, and this study provided a preliminary study for better guidance of clinical drug use.
RESUMO
OBJECTIVE: Detrusor overactivity with detrusor underactivity (DO-DU) is classically described in frail institutionalized elderly patients, but we have also observed this diagnosis in younger populations. This research aims to identify the differences between two age groups of DO-DU patients. MATERIALS AND METHODS: This study included DO-DU patients from a single center from 2012 to 2023. Patients were divided into two groups: the "Younger" group (aged less than 70 years) and the "Older" group (aged 70 years or older). We separately compared demographics, the number of risk factors considered to affect bladder function, clinical presentations, and urodynamic findings between these two groups in each gender. RESULTS: There were 210 patients included in the analysis, with 50.48% in the younger group and 49.52% in the older group. The median ages of males and females in the younger group were 57 and 62 years, whereas the median ages of males and females in the older group were 76.5 and 76 years. Multiple sclerosis exhibited statistically significant prevalence in the younger patients (7.7% vs. 0%, p = 0.03 in males and 19.9% vs. 4.6% in females). While diabetes mellitus (DM) was more prevalent in the older males (20.0% vs. 4.6%, p = 0.01), transabdominal hysterectomy was more common in the younger females (46.3% vs. 25%, p = 0.04). 69.8% of the younger group and 71.2% of the older group have at least one risk factor that impact their bladder function. There was no statistically significant difference between the two groups across various risk factor categories. The older males reported a higher incidence of urgency (78.3% vs. 58.5%, p = 0.02) and urge incontinence (61.7% vs. 32.3%, p < 0.01), while the younger females reported a higher incidence of straining during voiding on history (46.3% vs. 20.5%, p = 0.01). The younger males exhibited a greater volume of strong desire to void (385 vs. 300 mL, p = 0.01), maximal cystometric capacity (410 vs. 300 mL, p < 0.01), and a lower highest detrusor overactivity (DO) pressure (37 vs. 50.5 cmH2O, p = 0.02). The younger group had a higher postvoid residual (170 vs. 85 mL in males, p < 0.01 and 180 vs. 120 mL in females, p = 0.02). The voiding efficiency was lower in younger females (40% vs. 60%, p = 0.02). In both ages, the ICS detrusor contraction index and projected isovolumetric pressure 1 were similar. However, without considering risk factors, the older males had the highest DO pressure (57 vs. 29 cmH2O, p < 0.01), and the younger males had a higher voiding pressure (PdetQmax) than the older males (28 vs. 20 cmH2O, p = 0.02). CONCLUSION: DO-DU is not exclusive to elderly patients. It can also be diagnosed in individuals with risk factors regardless of age; therefore, clinicians need a high degree of suspicion, especially in patients who have risk factor(s) for DO and DU. A notable clinical differentiation is that older males diagnosed with DO-DU have a higher incidence of urgency and urge urinary incontinence, while younger females have a higher incidence of straining.
RESUMO
To study the distribution of trace elements in natural water of the Du River Source National Nature Reserve and to assess the water quality and health risks, Zhushan County in Hubei Province was selected as the study area. Element content in 361 natural water samples collected from Zhushan County were measured by ICP-MS, ICP-OES, and HG-AFS. The main anions and cations present in water samples from Zhushan County are Ca2+ and HCO3-. The water chemistry is predominantly influenced by the weathering of carbonate rocks. The water samples with high content of selenium (Se) (0â¼82.9 µg/L, mean 4.6 µg/L) in natural water in Zhushan County are mainly distributed in the northern part of Zhushan. The strontium (Sr) content of 49.6% of the water samples (0.001-2.177 mg/L, mean 0.234 mg/L) reached the criteria of natural mineral water for drinking in China (Sr ≥ 0.2 mg/L), which is distributed throughout the county. The high content of metasilicic acid (H2SiO3) (0.026-35.910 mg/L, mean 12.598 mg/L) and zinc (Zn) (0â¼407.218 µg/L, mean 12.406 µg/L) are concentrated in northern Zhushan County. 99.7% water samples were freshwater and 98.9% meet the criteria of "good" water quality. All of the natural water samples have low health risk and low heavy metal pollution. 6.1% water samples meet the criteria of Se-type mineral water, while 45.4% meet the criteria of Sr-type mineral water, and 4.4% water samples meet the criteria of "low sodium, high Se, and high Sr" mineral water. Zhushan County has the potential for Se-type mineral water and Sr-type mineral water development. The findings of this study hold immense significance for the public health implications of drinking water in Du River Source, thereby offering valuable insights for effective water resources management.

BACKGROUND: Schizophrenia spectrum disorders (SSDs) are a group of psychiatric disorders characterized by positive and negative symptoms as well as cognitive impairment that can significantly affect daily functioning. METHOD: We reviewed evidence-based strategies for improving cognitive function in patients with SSDs, focusing on the Canadian landscape. RESULTS: Although antipsychotic medications can address the positive symptoms of SSDs, cognitive symptoms often persist, causing functional impairment and reduced quality of life. Moreover, cognitive function in patients with SSDs is infrequently assessed in clinical practice, and evidence-based recommendations for addressing cognitive impairment in people living with schizophrenia are limited. While cognitive remediation (CR) can improve several domains of cognitive function, most individuals with SSDs are currently not offered such an intervention. While the development of implementation strategies for CR is underway, available and emerging pharmacological treatments may help overcome the limited capacity for psychosocial approaches. Furthermore, combining pharmacological with non-pharmacological interventions may improve outcomes compared to pharmacotherapy or CR alone. CONCLUSION: This review highlights the challenges and discusses the potential solutions related to the assessment and management of cognitive impairment to help mental health-care practitioners better manage cognitive impairment and improve daily functioning in individuals with SSDs.
Improving Thinking Skills in People With Schizophrenia: A Focus on CanadaPlain Language SummarySchizophrenia spectrum disorders (SSDs) are mental health conditions that can cause a mix of symptoms making everyday life difficult for people. For example, some people might experience positive symptoms like seeing and hearing things that are not there, having false believes, or feeling suspicious. Others might experience negative symptoms like isolating from social interactions, having trouble showing emotion, or finding it hard to connect with others. Finally, they might also have trouble with thinking skills, like paying attention, planning and organizing, remembering things, or understanding social cues. While some medicines can help with some of the symptoms, they often do not help with improving thinking skills. In addition, these thinking problems are not checked often enough in patients with SSDs. In fact, there are not many proven ways to help with these issues. One method that can help with thinking skills is called cognitive remediation (CR), but it is not offered to most people with SSDs. There are ongoing efforts to make CR more available. It is also possible that CR may be combined with new medicines to make it work better than using just one treatment. This article looks at ways to improve thinking skills in people with SSDs, with a focus on what is happening in Canada. We present the challenges and possible solutions for checking and managing thinking problems, to help health-care workers better care for people with SSDs.
RESUMO
BACKGROUND AND OBJECTIVE: Peach allergy is a prevalent cause of food allergy. Despite the repertoire of allergens available for molecular diagnosis, there are still patients with undetectable IgE levels to peach allergens but presenting symptoms after its ingestion. The objective of this study was to investigate the allergenic profile in a patient population with symptoms produced by peach. METHODS: An exploratory retrospective study was performed with patients presenting symptoms after the ingestion of peach. Forty-two patients were included in the study. The allergenic profile of individual patients was investigated by immunoblot. A serum pool was prepared with the sera that recognized a 70 kDa band. This pool was used to detect this protein in peach peel and pulp and to identify the 70 kDa protein in 2D immunoblot. Spots recognized in the 2D immunoblot were sequenced by LC-MS/MS. Inhibition studies were performed between peach peel and almond. RESULTS: Twenty-two patients (52.4%) recognized the 70 kDa protein in immunoblot. This protein was recognized in peel and pulp. Two different spots were observed in 2D-PAGE, both were identified as (R)-mandelonitrile lyases (RML) with high amino acid similarity with Pru du 10. Peach RML were partially inhibited with an almond extract. No association was found between any reported symptom and sensitization to RML. RML-sensitized patients were older and reported pollen associated respiratory symptoms more frequently than negative patients. CONCLUSION: A new peach allergen, a RML, homologous of Pru du 10, recognized by 52% of the population has been identified.
RESUMO
BACKGROUND: There are two parallel systems in Malaysian primary healthcare services: government funded public primary care and privately-owned practices. While there have been several studies evaluating antibiotic utilisation in Malaysian public healthcare, there is a lack of literature on the use of antibiotics in the private sector. There is a dire need to evaluate the more recent performance of public vs. private community healthcare in Malaysia. As such, this study aimed at measuring and comparing the utilisation of antibiotics in the public and private community healthcare sectors of Malaysia in 2018-2021. METHODS: This study was a retrospective analysis of antibiotic utilisation in Malaysian primary care for the period of 1 January 2018 until 31 December 2021 using the nationwide pharmaceutical procurement and sales data from public and private health sectors. Rates of antibiotic utilisation were reported as Defined Daily Doses per 1000 inhabitants per day (DID) and stratified by antibiotic classes. The secondary analysis included proportions of AWaRe antibiotic category use for each sector and proportion of antibiotic utilisation for both sectors. RESULTS: The overall national antibiotic utilisation for 2018 was 6.14 DID, increasing slightly to 6.56 DID in 2019, before decreasing to 4.54 DID in 2020 and 4.17 DID in 2021. Private primary care antibiotic utilisation was almost ten times higher than in public primary care in 2021. The public sector had fewer (four) antibiotic molecules constituting 90% of the total antibiotic utilisation as compared to the private sector (eight). Use of Access antibiotics in the public sector was consistently above 90%, while use of Access category antibiotics by the private sector ranged from 64.2 to 68.3%. Although use of Watch antibiotics in the private sector decreased over the years, the use of Reserve and 'Not Recommended' antibiotics increased slightly over the years. CONCLUSION: Antibiotic consumption in the private community healthcare sector in Malaysia is much higher than in the public sector. These findings highlight the need for more rigorous interventions targeting both private prescribers and the public with improvement strategies focusing on reducing inappropriate and unnecessary prescribing.

Tetralogy of Fallot (TOF) and double-outlet right ventricle (DORV) are conotruncal defects resulting from disturbances of the second heart field and the neural crest, which can occur as isolated malformations or as part of multiorgan syndromes. Their etiology is multifactorial and characterized by overlapping genetic causes. In this chapter, we present the different genetic alterations underlying the two diseases, which range from chromosomal abnormalities like aneuploidies and structural mutations to rare single nucleotide variations affecting distinct genes. For example, mutations in the cardiac transcription factors NKX2-5, GATA4, and HAND2 have been identified in isolated TOF cases, while mutations of TBX5 and 22q11 deletion, leading to haploinsufficiency of TBX1, cause Holt-Oram and DiGeorge syndrome, respectively. Moreover, genes involved in signaling pathways, laterality determination, and epigenetic mechanisms have also been found mutated in TOF and/or DORV patients. Finally, genome-wide association studies identified common single nucleotide polymorphisms associated with the risk for TOF.

Ventricular septal defects (VSDs) are recognized as one of the commonest congenital heart diseases (CHD), accounting for up to 40% of all cardiac malformations, and occur as isolated CHDs as well as together with other cardiac and extracardiac congenital malformations in individual patients and families. The genetic etiology of VSD is complex and extraordinarily heterogeneous. Chromosomal abnormalities such as aneuploidy and structural variations as well as rare point mutations in various genes have been reported to be associated with this cardiac defect. This includes both well-defined syndromes with known genetic cause (e.g., DiGeorge syndrome and Holt-Oram syndrome) and so far undefined syndromic forms characterized by unspecific symptoms. Mutations in genes encoding cardiac transcription factors (e.g., NKX2-5 and GATA4) and signaling molecules (e.g., CFC1) have been most frequently found in VSD cases. Moreover, new high-resolution methods such as comparative genomic hybridization enabled the discovery of a high number of different copy number variations, leading to gain or loss of chromosomal regions often containing multiple genes, in patients with VSD. In this chapter, we will describe the broad genetic heterogeneity observed in VSD patients considering recent advances in this field.

INTRODUCTION: Xenografts of androgen-independent human DU145 prostate metastatic carcinomas implanted in nu/nu male mice have revealed a significant survival after a prooxidant anticancer treatment consisting of a combination of menadione bisulfite and sodium ascorbate (VK3:VC). METHODS: Implanted samples of diaphragm carcinomas from longest survived mice from either oral, intraperitoneal (IP), or both oral and IP treatment groups were assessed with light, scanning, and transmission electron microscopy to analyze morphologic damages. RESULTS: Compared with previous fine structure data of in vitro untreated carcinomas, the changes induced by oral, IP, and oral with IP VK3:VC treatment dismantled those xenografts with autoschizis, and necrotic atrophy was accomplished by cell's oxidative stress whose injuries were consequent to reactivated deoxyribonucleases and ribonucleases. Tumor destructions resulted from irreversible damages of nucleus components, endoplasmic reticulum, and mitochondria there. Other alterations included those of the cytoskeleton that resulted in characteristic self-excisions named " autoschizis." All these injuries lead resilient cancer cells to necrotic cell death. CONCLUSION: The fine structure damages caused by VK3:VC prooxidant combination in the human DU145 prostate xenografts confirmed those shown in vitro and of other cell lines with histochemistry and biomolecular investigations. These devastations incurred without damage to normal tissues; thus, our data brought support for the above combination to assist in the treatment of prostate cancers and other cancers.
RESUMO
Depleted uranium (DU) retains the radiological toxicities, which accumulates preferentially in the kidneys. Hedgehog (Hh) pathway plays a critical role in tissue injury. However, the role of Hh in DU-induced nephrotoxicity was still unclear. This study was carried out to investigate the effect of Gli2, which was an important transcription effector of Hh signaling, on DU induced nephrotoxicity. To clarify it, CK19 positive tubular epithelial cells specific Gli2 conditional knockout (KO) mice model was exposed to DU, and then histopathological damage and Hh signaling pathway activation was analyzed. Moreover, HEK-293 T cells were exposed to DU with Gant61 or Gli2 overexpression, and cytotoxicity of DU as analyzed. Results showed that DU caused nephrotoxicity accompanied by activation of Hh signaling pathway. Meanwhile, genetic KO of Gli2 reduced DU-induced nephrotoxicity by normalizing biochemical indicators and reducing Hh pathway activation. Pharmacologic inhibition of Gli1/2 by Gant61 reduced DU induced cytotoxicity by inhibiting apoptosis, ROS formation and Hh pathway activation. However, overexpression of Gli2 aggravated DU-induced cytotoxicity by increasing the levels of apoptosis and ROS formation. Taken together, these results revealed that Hh signaling negatively regulated DU-inducted nephrotoxicity, and that inhibition of Gli2 might serve as a promising nephroprotective target for DU-induced kidney injury.

The purpose of this literature review is to evaluate the extant research addressing food insecurity and mental health among street-involved 2S/LGBTQI+ youth in Canada. Searches were undertaken in academic databases, Google, and Google Scholar for relevant research articles, reports, and grey literature. Our team found nil research specifically addressing food insecurity and the mental health of street-involved 2S/LGBTQI+ youth in Canada. Given that, contextual and contributory factors affecting the mental health and food security of this population are discussed. The available research demonstrates a significant misalignment between the existing support mechanisms and the requirements of this specific population. This underscores the urgent necessity for the establishment of structurally competent, safe, and easily accessible resources. Moreover, there is a clear imperative for additional research endeavors aimed at addressing knowledge deficiencies. These efforts are crucial in empowering dietitians to facilitate enhanced interdisciplinary collaboration, thereby fostering the creation of sustainable, accessible, and appropriate food systems tailored to the needs of this vulnerable demographic.
RESUMO
Land2Lab is an evolving community-based intergenerational program that brings together Elders and youth on the land and in the kitchen and lab to share and celebrate Mi'kmaw foodways. Rooted in an Etuaptmumk-Two Eyed Seeing (E-TES) perspective, which acknowledges both Indigenous and Western ways of knowing, the project to date has featured seasonal food workshops, involvement in a children's summer math camp, a food safety training workshop for teens, and the development of an online toolkit. The project was guided by the Mi'kmaw principle of Netukulimk, which reinforces respect for Mother Earth and stewardship of the land, water, and air for subsequent generations. Involvement of community leaders has been key to successful planning and implementation. While technology plays an important role, lessons learned on the land are critical and will inform efforts to include language and ceremony in future programming. Dietitians are encouraged to support Indigenous-led land-based learning in support of the profession's commitment to reconciliation.

Purpose: This study aimed to assess the reliability and validity of an online approach to monitoring food affordability in Ontario using the updated Ontario Nutritious Food Basket (ONFB).Methods: The ONFB was priced online in 12 large multi-chain grocery stores to test intra-/inter-rater reliability using percent agreement and intra-class correlations (ICCs). Then, the ONFB was priced in-store and online in 28 stores to estimate food price differences using paired t-tests and Pearson's correlation for all (n =1708) and matched items (same product/brand and purchase unit) (n = 1134).Results: Intra-/inter-rater agreement was high (95.4%/81.6%; ICC = 0.972, F = 69.9, p < 0.001). On average, in-store prices were less than $0.02 lower than online prices. There were no significant differences between mean in-store and online prices for all items (t = 0.504 p = 0.614). The mean price was almost perfectly correlated between in-store and online (fully matched: R = 0.993 p < 0.001; all items: R = 0.967 p < 0.001). Online monthly ONFB estimates for a family of four were strongly correlated (R = 0.937 p < 0.001) with estimates calculated using in-store data.Conclusions: Online pricing is a reliable and valid approach to food costing in Ontario that contributes to modernizing the monitoring of food affordability in Canada and abroad.

Staphylococcus aureus is a gram-positive bacteria, and its virulence factors can cause many kinds of infections, such as pneumonia, sepsis, enteritis and osteomyelitis. Traditional antibiotics can not only kill bacteria, but also easily lead to bacterial resistance. Jingfang Mixture (JFM) has the effects of inducing sweating and relieving the exterior, dispelling wind and eliminating dampness, and is commonly used in clinic to prevent and treat epidemic diseases and infectious diseases. The main purpose of this study is to explore the inhibitory effect of JFM on alpha-hemolysin (Hla) of S. aureus and to alleviate the damage caused by Hla. We found that JFM could inhibit the hemolytic activity, transcription level and neutralizing activity of Hla in a dose-dependent manner at the concentrations of 125, 250 and 500 µg/mL, without affecting the growth of bacteria. In addition, JFM reduced the damage of Hla to A549 cells and the release of lactate dehydrogenase (LDH). We also observed that in the S. aureus - induced pneumonia mouse model, JFM could significantly prolong the life of mice, reduce the bacterial load in the lungs, significantly improve the pathological state of the lungs and alleviate the damage caused by inflammatory factors, and the pathogenicity of gene deletion strain DU 1090 of S. aureus to pneumonia mice was also significantly reduced. In conclusion, this study proved that JFM is a potential drug against S. aureus infection, and this study provided a preliminary study for better guidance of clinical drug use.

This study, conducted in Germany, examines the role of maternal soothing strategies to explain the association of maternal self-efficacy with infant regulation (crying and sleeping behavior). Questionnaire data of 150 mothers, living in Germany, with mixed ethnic and educational backgrounds were collected when infants were 3 and 7 months old. Two types of maternal soothing strategies were distinguished: close soothing, involving close physical and emotional contact, and distant soothing, involving physical and emotional distancing from the infant. A cross-sectional SEM at 3 months indicated that maternal self-efficacy is associated with reported infant regulation through distant soothing strategies. Low maternal self-efficacy was associated with frequent maternal use of distant soothing, which in turn was related to reported infant regulation problems, that is, non-soothability and greater crying frequency. Frequent use of close soothing was associated with reported infant sleeping behavior, that is, frequent night-time awakenings. A longitudinal SEM further indicated that the effects of close soothing persisted at least until the infants' age of 7 months. The study showed how low maternal self-efficacy, increased use of distant soothing, and reported early infant regulation problems are intertwined and that, due to their persisting positive effect on infant soothability, close soothing better supports infant development.
Este estudio examina el papel de las estrategias calmantes maternas para explicar la asociación entre auto efectividad materna y la regulación del infante (comportamiento de llanto y de dormir). Información de cuestionario de N = 150 madres de trasfondos étnicos y educativos mixtos se recogió cuando los infantes tenían tres y siete meses de nacidos. Dos tipos de estrategias calmantes maternas se identificaron: estrategia calmante cercana, la cual trata del contacto físico y emocional cercano, y estrategia calmante distante, la cual trata del distanciamiento físico y emocional con el infante. Un estudio de Modelo de Ecuación Estructural (SEM) transversal a los tres meses indicó que la auto efectividad materna se asocia con la reportada regulación del infante a través de estrategias calmantes distantes. La baja auto efectividad materna se asoció con el frecuente uso materno de estrategias calmantes distantes, lo cual a su vez se relacionó con los reportados problemas de regulación del infante, tales como el no calmarse y la mayor frecuencia del llanto. El uso frecuente de estrategias calmante cercanas se asoció con el reportado comportamiento de dormir del infante, tal como el frecuente despertar nocturno. Un estudio de tipo SEM longitudinal indicó más allá que los efectos de las estrategias calmantes cercanas persistían por lo menos hasta que los infantes tenían siete meses de edad. El estudio mostró cómo la baja auto efectividad materna, el uso incrementado de estrategias calmantes distantes, así como los reportados tempranos problemas de regulación del infante están entremezclados y que, debido a su persistente efecto positivo en calmar al infante, las estrategias calmantes cercanas apoyan mejor el desarrollo del infante.
Cette étude examine le rôle des stratégies maternelles d'apaisement pour expliquer le lien de l'auto-efficacité maternelle avec la régulation du nourrisson (pleurs et comportement du sommeil). Des données d'une questionnaire de N = 150 mères issues de milieux ethniques et éducationnels différents ont été recueillies quand les nourrissons avaient trois et sept mois. Deux types de stratégies maternelles d'apaisement ont été distingués: l'apaisement proche, avec un contact physique et émotionnel proche, et l'apaisement distant, avec une distanciation physique et émotionnelle du nourrisson. Une coupe transversale SEM à trois mois a indiqué que l'auto-efficacité maternelle est liée à la régulation infantile signalée au travers de stratégies d'apaisement distantes. Une auto-efficacité maternelle faible était liée à l'utilisation maternelle fréquente de stratégies d'apaisement, qui à son tour était liée aux problèmes signalés de régulation du nourrisson, comme par exemple le fait de ne pas pouvoir être apaisé ou une fréquence de pleurs plus grande. L'utilisation fréquente de stratégies d'apaisement proche était liée au comportement de sommeil du nourrisson signalé, comme par exemple des réveils nocturnes fréquents. Un SEM longitudinal a de surcroit indiqué que les effets de stratégies d'apaisement proches persistaient au moins jusqu'à l'âge de sept mois des nourrissons. L'étude a montré comment l'auto-efficacité maternelle faible, une utilisation accrue de stratégies d'apaisement distant et les problèmes signalés de régulation précoce des nourrissons sont imbriqués et que, du fait de leur effet positif persistant sur l'apaisement du nourrisson, les stratégies d'apaisement proches soutiennent mieux le développement du nourrisson.

Understanding deficits in recognition of infant emotions in mothers with mental illnesses is limited by the lack of validated instruments. We present the development and content validation of the infant facial emotion recognition tool (InFER) in India to examine the ability of mothers to detect the infants' emotions. A total of 164 images of infant faces in various emotional states were gathered from the parents of four infants (two male and two female: up to 12 months old). Infant emotion in each image was identified by the respective mother. Content validation was carried out by 21 experts. Images with ≥70% concordance among experts were selected. The newly developed tool, InFER, consists of a total 39 infant images representing the six basic emotions. This tool was then administered among mothers during their postpartum period-10 healthy mothers and 10 mothers who had remitted from any schizophrenia spectrum disorder, bipolar affective disorder or major depressive disorder. The mean age and mean years of education for both groups were comparable (ageâ¼25 years, education â¼15 years). A significant difference was found between the two groups in their ability to recognize infant emotions (Mann-Whitney U = 12.5; p = 0.004). InFER is a promising tool in Indian settings for understanding maternal recognition of infant emotions.
La comprensión de los déficits en el reconocimiento de las emociones del infante en madres con enfermedades mentales está limitada por la falta de instrumentos validados. Presentamos el desarrollo y la validación de contenido de una herramienta para reconocer la emoción facial del infante (InFER) en la India. para examinar la habilidad de las madres para detectar las emociones del infante. Se recogió un total de 164 imágenes de caras de infantes en varios estados emocionales, aportadas por los progenitores de 4 infantes (dos varones y dos niñas: de hasta 12 meses de edad). La mamá respectiva identificó la emoción del infante en cada imagen. La validación del contenido la llevaron a cabo 21 expertos. Para la construcción de esta herramienta se seleccionaron las imágenes que presentaban el ≥70% de concordancia entre los expertos. La recientemente desarrollada herramienta, InFER está compuesta de un total de 39 imágenes de infantes las cuales representan las seis emociones básicas. Esta herramienta entonces se puso en práctica entre madres durante su período de postparto 10 madres saludables y 10 madres que habían sido remitidas en relación con cualquiera de los trastornos de la gama de la esquizofrenia, el trastorno afectivo bipolar o un trastorno depresivo mayor. El promedio de edad y el promedio de años de educación en ambos grupos eran comparables (edad â¼25 años, educación â¼15years). Una diferencia significativa se encontró entre los dos grupos en cuanto a su habilidad de reconocer las emociones del infante (MannWhitney U = 12.5; p = 0.004). InFER es una herramienta prometedora en entornos de la India para comprender el reconocimiento materno de las emociones del infante.

Un total de 164 images de visages de bébés dans des états émotionnels variés ont été assemblées de parents de 4 bébés (deux garçons et deux filles: jusqu'à l'âge de 12 mois) L'émotion du bébé dans chaque image a été identifiée par la mère respective. La validation du contenu a été faite par 21 experts. Des images avec ≥70% de concordance entre les experts ont été sélectionnées pour la construction de l'outil. Ce nouvel outil, InFER, consiste en un total de 39 images de bébés représentant les six émotions de base. Cet outil a ensuite été utilisé chez des mères durant leur période postpartum 10 mères en bonne santé et 10 mères s'étant remises soit d'un trouble du spectre schizophrénique, soit d'un trouble affectif bipolaire ou d'un trouble dépressif majeur. La moyenne d'âge et la moyenne d'années d'éducation pour les deux groupes étaient comparables (âgeâ¼25ans, éducation â¼15ans). Une différence importante a été trouvée entre les deux groupes dans leur capacité à reconnaître les émotions du bébé (MannWhitney U = 12,5; p = 0,004). InFER est un outil prometteur dans les contextes de l'Inde pour comprendre la reconnaissance maternelle des émotions du bébé.

The field of infant mental health (IMH) has offered valuable insights into the critical importance of social-emotional development, including the enduring influence of early experiences throughout life. Maternal and Child Health (MCH) nurses are ideally placed to facilitate knowledge sharing with parents. This Australian-based qualitative exploratory descriptive study explored how MCH nurses incorporate IMH in their clinical practice, and how they share this information with caregivers. Ten community-based MCH nurses participated in voluntary, semi-structured interviews which were transcribed verbatim and analyzed thematically. Findings identified five themes that characterized how MCH nurses incorporated IMH concepts into their practice. These themes were: prioritizing physical health promotion activities, highlighting infant communications, variations in knowledge and application of IMH concepts, workplace time schedules, and the relational nature of the work. Recommendations include encouraging IMH as a health promotion activity, facilitating IMH assessment, further education, reflective supervision, and extension of predetermined appointment times to enable knowledge and skill sharing. Further research is also recommended to provide additional insights into how nurses with IMH training promote and share IMH concepts with caregivers. Adoption of these recommendations would further enhance the care given to families and the role of the MCH nurses.
El campo de la salud mental infantil (IMH) ha ofrecido perspectivas valiosas sobre la suma importancia del desarrollo socioemocional en los primeros años para el desarrollo social y emocional posterior. Las enfermeras de la salud materno-infantil (MCH) se encuentran en posición ideal para facilitar el proceso de compartir conocimiento con los progenitores. Este estudio cualitativo, exploratorio y descriptivo, llevado a cabo en Australia, exploró cómo las enfermeras MCH incorporan IMH en sus prácticas clínicas y cómo ellas comparten esta información con los cuidadores. Un grupo de enfermeras MCH de base comunitaria participó en entrevistas voluntarias semiestructuradas. Las entrevistas se transcribieron palabra por palabra y se analizaron temáticamente. Los resultados identificaron cinco temas que caracterizaban cómo incorporaron los conceptos de IMH en su práctica. Estos temas fueron: actividades para promover el darle prioridad a la salud física, enfatizar las comunicaciones del infante, variaciones en el conocimiento y la aplicación de conceptos de IMH, tablas de horarios del lugar de trabajo y la naturaleza relacional del trabajo. Entre las recomendaciones se incluyen el fomentar IMH como una actividad de promoción de la salud, facilitar la evaluación de IMH, más educación, supervisión con reflexión, así como extensión del horario de citas predeterminado para permitir el proceso de compartir conocimiento y habilidades. También se recomienda más investigación para ofrecer perspectivas adicionales de cómo las enfermeras con entrenamiento de IMH promueven y comparten los conceptos de IMH con los cuidadores. La adopción de estas recomendaciones mejoraría más el cuidado que se ofrece a familias y el papel de las enfermeras MCH.
Le domaine de la santé mentale du nourrisson (IMH en anglais) a permis de mieux comprendre l'importance critique du développement socio-émotionnel dans les premières années pour le développement social et émotionnel ultérieur. Les infirmiers et infirmières de la Santé Maternelle et de l'Enfant (MCH en anglais) sont idéalement situées pour faciliter le partage des connaissances avec les parents. Cette étude Qualitative Exploratoire Descriptive, en Australie, a exploré comment les infirmier/infirmières MCH incorporent l'IMH dans leur pratique clinique et comment ils/elles partagent cette information avec les personnes prenant soin des enfants. Une cohorte de 10 infirmiers/infirmières MCH basées dans leur communauté ont participé à des entretiens volontaires semi-structurés. Les entretiens ont été transcrits verbatim et analysé de manière thématique. Les résultats ont identifié cinq thèmes qui ont caractérisé les concepts IMH dans leur pratique. Ces thèmes étaient: donner la priorité à la promotion d'activités de santé physique, la mise en évidence des communications du nourrisson, les variations dans les connaissances et l'application des concepts IMH, les emplois du temps du lieu de travail et la nature relationnelle du travail. Les recommandations incluent la nécessité d'encourager l'IMH en tant qu'activité de promotion de la santé, la facilitation de l'évaluation IMH, une formation supplémentaire, une supervision de réflexion et l'extension de rendez-vous pour développer les connaissances et partager les compétences. De plus amples recherches sont recommandées afin d'éclairer la manière dont les infirmiers/infirmières formées en IMH promeuvent et partagent les concepts IMH avec les personnes prenant soin des enfants. L'adoption de ces recommandations pour améliorer davantage le soin offert aux familles et les rôles des infirmiers/infirmières MCH.

Infant carrying may have beneficial effects on the parent-infant relationship but only limited research has been conducted in this area. Therefore, the main aim of the current study was to investigate whether infant carrying is associated with parental reflective functioning, parental bonding, and parental (emotional) and behavioral responses to infant crying, key elements within the parent-infant relationship, promoting infant development. Parents reporting high levels (N = 389) of infant carrying (six times a week or daily) and parents reporting low levels (N = 128) of infant carrying (less than once a week or not at all) who participated in an online survey about the developing parent-infant relationship in Germany were included in the present study. Standardized questionnaires were used to assess parental reflective functioning, parental bonding impairments, and emotional responses to infant crying. Further insensitive (non-responsive and hostile) behaviors in response to infant crying were assessed. Parents with high levels of infant carrying showed better parental reflective functioning, lower parental bonding problems, less negative emotions, and less insensitive behaviors in response to infant crying.
Cargar al infante pudiera tener efectos beneficiosos para la relación progenitorinfante, pero sólo una limitada investigación se ha llevado a cabo en esta área. Por tanto, el objetivo principal del presente estudio fue investigar si cargar al infante se asocia con que el funcionamiento con reflexión del progenitor, los lazos de afectividad del progenitor, así como las respuestas de comportamiento (emocional) del progenitor al llanto del infante, elementos claves dentro de la relación progenitorinfante, promueven el desarrollo del infante. Se incluyó en el presente estudio a los progenitores que reportaron altos niveles (N=389) de llanto del infante (seis veces por semana o diariamente) y a los progenitores que reportaron bajos niveles (N=128) del llanto del infante (menos de una vez por semana o nunca), quienes participaron en una encuesta electrónica acerca de la relación progenitorinfante en desarrollo, en Alemania. Se usaron cuestionarios estandarizados para evaluar el funcionamiento con reflexión del progenitor, los impedimentos de lazos afectivos del progenitor, así como las respuestas emocionales al llanto del infante. Se evaluaron además comportamientos insensibles (sin respuesta afectiva y hostil) como respuesta al llanto del infante. Los progenitores con altos niveles de cargar al infante demostraron un mejor funcionamiento con reflexión del progenitor, más bajos problemas en cuanto a lazos de afectividad del progenitor, menos emociones negativas y menos comportamientos insensibles como respuesta al llanto del infante.
Porter un bébé peut avoir des effets bénéfiques sur la relation parentbébé mais il n'existe que peu de recherches sur ce domaine. C'est pour cette raison que le but principal de cette étude était d'investiguer si le fait de porter un bébé est lié avec une fonction réflexive parentale, le lien parental et les réactions parentales (émotionnelles) et comportementales aux pleurs du bébé, des éléments clef au sein de la relation parentbébé, promouvant le développement du bébé. Les parents faisant état de niveaux élevés (N=389) de portage du bébé (six fois par semaine ou tous les jours) et les parents faisant état de niveaux bas (N=128) de portage du bébé (moins d'une semaine ou pas du tout) qui ont participé à un questionnaire en ligne sur la relation parentbébé se développant en Allemagne ont été inclus dans cette étude. Des questionnaires standardisés ont été utilisés afin d'évaluer la fonction réflexive parentale, les troubles du lien parental, et les réactions émotionnelles aux pleurs du bébé. D'autres comportement insensibles (nonréactifs et hostile) en réaction aux pleurs du bébé ont été évalués. Les parents avec des niveaux élevés de portage du bébé ont fait preuve d'une meilleure fonction réflexive parentale, de moins de problèmes de lien parental, de moins d'émotions négatives, et de moins de comportements insensibles en réaction aux pleurs du bébé.

In this cross-sectional study performed in Canada, we evaluated the frustration levels of prepartum and postpartum mother and father couple-pairs. Our goal was to determine if there were differences in frustration levels between mothers and fathers while listening to prolonged infant crying, and further, how frustration levels might differ between prepartum and postpartum samples. Using two discrete groups, prepartum (Sample 1; N = 48) and postpartum (Sample 2; N = 44) mother and father couple-pairs completed 600 s of listening to audio-recorded infant cry sounds. Participants continuously reported their subjective frustration using a computerized Continuous Visual Analog Scale (CVAS). There was no significant difference in frustration responses between mothers and fathers across both prepartum and postpartum samples. Postpartum mothers and fathers experienced greater frustration than their prepartum counterparts, and frustration increased faster in postpartum couples compared to prepartum couples. Informing first-time parents of the universal experiences of frustration to prolonged crying bouts that are characteristic of their infant's early weeks of life may lead to greater understanding towards their infant, and perhaps decreased instances of harmful responses.
En este estudio transeccional, evaluamos los niveles de frustración de las parejas de mamás y papás antes y después del parto. Nuestro propósito fue determinar si hay diferencias entre mamás y papás en cuanto a los niveles de frustración mientras escuchan el prolongado llanto del infante, y cómo los niveles de frustración pudieran diferir entre gruposmuestra antes y después del parto. Usando dos grupos discretos, antes del parto (grupomuestra 1; N = 48) y después del parto (grupomuestra 2; N = 44), las parejas de mamás y papás completaron 600 segundos escuchando sonidos grabados en audio de llanto de infante. Los participantes continuamente reportaron su frustración subjetiva usando una escala análoga visual continua computarizada (CVAS). No hubo diferencia significativa en las respuestas de frustración entre mamás y papás a lo largo de los gruposmuestra tanto antes del parto como después del parto. Las mamás y papás en el grupomuestra después del parto experimentaron mayor frustración que sus homólogos en el grupomuestra antes del parto, y la frustración aumentó más rápido en las parejas del grupomuestra después del parto tal como se les comparó con las parejas del grupomuestra antes del parto. Estos resultados sugieren que las parejas primíparas posterior al parto están más propensas a experimentar considerables cantidades de frustración como respuesta al llanto del infante después que el bebé ha nacido. Informarles a los progenitores primerizos acerca de las experiencias generales de la frustración a los prolongados ataques de llanto que son característicos de las primeras semanas de vida de su infante pudiera llevar a una mayor comprensión hacia su infante y quizás disminuir las instancias de respuestas dañinas.
Dans cette étude transversale nous avons évalué les niveaux de frustration des couplespaires mère et père avant et après la naissance. Notre but était de déterminer s'il existe des différences entres les mères et les pères dans leurs niveaux de frustration en entendant des pleurs de bébé prolongés et de quelle manière les niveaux pourraient différer entre les échantillons avant la naissance et après la naissance. En utilisant deux groupes discrets, avant la naissance (Echantillon 1; N = 48) et après la naissance (Echantillon 2; N = 44) les couplespaires mère et père ont écouté 600 seconds d'enregistrements de pleurs de bébés. Les participants ont fait état de leur frustration subjective en utilisant une échelle analogique visuelle continue informatisée (CVAS). Il s'est avéré n'y avoir aucune différence importante dans les réactions de frustration entre les mères et les pères au travers des échantillons à la fois avant l'accouchement et après l'accouchement. Ces résultats suggèrent que les coupes postpartum primipares sont plus à même de faire l'expérience de niveaux élevés de frustration en réaction aux pleurs du bébé une fois le bébé arrivé. Informer les parents qui sont parents pour la première fois des expériences universelles de frustration aux crises de pleurs prolongées qui caractérisent les premières semaines de la vie des bébés peut mener à une plus grande compréhension de leur bébé et peutêtre à une baisse des case d réactions néfastes.

This study examined the associations between maternal depression and oxytocin in pregnancy, caregiving sensitivity and adult attachment style, and infant temperament. One hundred and six women recruited from a public hospital antenatal clinic in Australia, and their infants completed assessments at three time points (Time 1: pregnancy; Time 2: 3-month postpartum; Time 3: 12-month postpartum). Mothers completed self-report questionnaires assessing maternal depression symptom severity at Time 1-3, adult attachment style at Time 2, and infant temperament at Time 3. At Time 1, they also provided a blood sample to assess peripheral oxytocin levels, and at Time 2, participated in a parent-child interaction session, which was later coded for caregiving behavior (sensitivity). Neither maternal depression nor lower levels of oxytocin during pregnancy predicted difficult infant temperament; rather, it was predicted by non-Caucasian ethnicity. When all other variables were free to vary, adult attachment avoidance mediated an association between maternal depression during pregnancy and difficult infant temperament. Results highlight the potential value of interventions focusing on adult attachment insecurity for pregnant women and raise questions about associations between culture/ethnicity and infant temperament.
Cette étude a examiné les liens entre la dépression maternelle et l'oxytocine durant la grossesse, la sensibilité de la personne prenant soin de l'enfant, le style d'attachement adulte et le tempérament du nourrisson. Cent six femmes recrutées dans une clinique prénatale d'un hôpital public et leurs nourrissons ont rempli des évaluations à trois moments (Moment 1 : la grossesse; Moment 2 : 3 mois postpartum; Moment 3 12 mois postpartum). Les mères ont rempli des questionnaires d'autoévaluation évaluant la sévérité du symptôme de dépression maternelle aux Moments 1, 2, et 3, le style d'attachement adulte au Moment 2, et le tempérament du nourrisson au Moment 3. Au Moment 1 elles ont aussi donné un échantillon de sang afin d'évaluer les niveaux périphériques d'oxytocine, et au Moment 2 elles ont participé à une séance d'interaction parentenfant qui fut plus tard codée pour le comportement de soin (sensibilité). Ni la dépression maternelle ni des niveaux plus bas d'oxytocine durant la grossesse ont prédit un tempérament difficile du nourrisson. En fait ce dernier s'est avéré prédit par une ethnicité non blanche. Lorsque toutes les autres variables étaient libres de varier le fait d'éviter l'attachement adulte a servi de médiation dans le lien entre la dépression maternelle durant la grossesse et le tempérament difficile du nourrisson. Les résultats mettent en lumière la valeur potentielle des interventions qui mettent l'accent sur l'insécurité de l'attachement adulte pour les femmes enceintes et soulèvent des questions quant aux liens entre la culture/l'ethnicité et le tempérament du nourrisson.
Este estudio examinó las asociaciones entre depresión materna y oxitocina en el embarazo, la sensibilidad acerca de la prestación de cuidado y el estilo de afectividad adulta, así como el temperamento del infante. Ciento seis mujeres, reclutadas de la clínica antenatal de un hospital público, y sus infantes, completaron un instrumento evaluativo en 3 momentos (Momento 1: embarazo; Momento 2: 23 meses después del parto; Momento 3: 12 meses después del parto). Las madres completaron cuestionarios de autoinforme en los que evaluaban la severidad de los síntomas de depresión materna en los Momentos 1, 2 y 3, el estilo de afectividad adulta al Momento 2, así como el temperamento del infante al Momento 3. Al Momento 1, ellas también aportaron una muestra de sangre para evaluar los niveles perimetrales de oxitocina, y al Momento 2, participaron en una sesión de interacción progenitorinfante que luego fue codificada en cuanto al comportamiento de prestación de cuidado (sensibilidad). Ni la depresión materna ni los bajos niveles de oxitocina durante el embarazo predijeron el temperamento difícil del infante; más bien, eso lo predijo la etnicidad no caucásica. Cuando todas las otras variables estaban libres para variar, la evasión de la afectividad adulta sirvió de mediadora en una asociación entre depresión materna durante el embarazo y temperamento difícil del infante. Los resultados subrayan el valor potencial de intervenciones que se enfoquen en la inseguridad de la afectividad adulta para mujeres embarazadas y plantean preguntas acerca de las asociaciones entre cultura/etnicidad y el temperamento del infante.
