"It is like a curse". The lived experiences of the intersection of intergenerational violence, pregnancy, and intimate partner violence among urban Wisconsin Indigenous women.

BACKGROUND: Intimate Partner Violence (IPV) is a significant public health concern that disproportionately impacts Indigenous American women more than any other ethnic/racial group in the United States. PURPOSE: This study aims to inform the work of nurses and allied health professionals by providing insight into the lived realities of Indigenous women in urban areas and how IPV manifests in the lives of Indigenous women. METHODS: Postcolonial and Indigenous feminist frameworks informed this qualitative study. Using thematic analysis, we analyzed data from semi-structured individual interviews with 34 Indigenous women in large urban areas in the upper Midwest. FINDINGS: This manuscript discusses one broad theme: experiences of IPV during pregnancy and the devastating impacts on women and their children in the form of intergenerational trauma. Under this broad theme, we identified two sub-themes: impacts of IPV on individual pregnancy experiences and linkages to adverse pregnancy-related outcomes related to physical IPV during the childbearing years. CONCLUSION: This Indigenous-led study informs the development of effective Indigenous-specific interventions to minimize barriers to accessing prenatal care and help-seeking when experiencing IPV to reduce the devastating consequences for Indigenous women and their families.

Screening of Galician grapevine varieties by SNPs, phenotypic traits, and phytopathology.

The genetic erosion of the European grapevine diversity in the last century has promoted the conservation of varieties in germplasm banks to prevent their disappearance. The study of these varieties is necessary as it would allow the diversification of the wine market, as well as provide a source of genes to face new pathogens or climate constraints. In this work, the grapevine varieties preserved in the "Estación de Viticultura e Enoloxía de Galicia" (EVEGA) Germplasm Bank (Ourense, Spain) were widely characterized, combining ampelography, ampelometry, agronomy, and phytopathology. Moreover, genetic characterization was carried out through the analysis of 48 single-nucleotide polymorphisms (SNPs). A Bayesian analysis based on the SNP data was carried out to define the genetic structure of the EVEGA Germplasm Bank, which allowed the differentiation of two main reconstructed panmictic populations (RPPs), confirming previous results obtained based on microsatellite markers (SSRs). A great diversity between varieties was found for almost every parameter evaluated for ampelography, ampelometry, phytopatology, phenology, and berry quality. A principal component analysis (PCA) performed with these phenotypical data allowed discrimination among some groups of varieties included in different genetic populations. This study allowed us to evaluate the grapevine diversity maintained in the EVEGA Germplasm Bank and characterize varieties of potential value for breeding programs of interest for the Galician viticulture.

Ethnic discrimination, acculturative stress, and sexual risk among Latinx emerging adults: Examining moderation effects of familism support and ethnic identity.

OBJECTIVES: Ethnic discrimination and acculturative stress play an important role in sexual risk behaviors for Latinx emerging adults, who are at disproportionate risk for sexually transmitted infections. Factors such as familism support and ethnic identity may be protective, yet research is limited. This study is guided by a culturally adapted stress and coping framework to examine associations of ethnic discrimination and acculturative stress with sexual risk behaviors (i.e., multiple sex partners, alcohol or drug use before sex, and condomless sex with a primary or casual partner), and examine the moderating roles of familism support and ethnic identity among Latinx emerging adults. METHOD: Participants were recruited from Arizona and Florida and were primarily female (51.3%) with a mean age of 21.48 years (SD = 2.06). Using cross-sectional data from 158 sexually active Latinx emerging adults, this study employed multiple logistic regression and moderation analyses. RESULTS: Higher levels of ethnic discrimination and pressure to acculturate were associated with fewer sex partners, and higher levels of pressure against acculturation were associated with increased condomless sex with a casual partner. The moderation effect of higher levels of familism support on pressure to acculturate was associated with fewer sex partners, and the moderation effect of higher levels of ethnic identity on pressure against acculturation was associated with decreased condomless sex with casual partners. CONCLUSIONS: Examining the results within a culturally informed theoretical framework supports that protective factors may help mitigate sexual risk factors among Latinx emerging adults experiencing acculturative stress.

Identification and phenotypic characterization of patients with LADA in a population of southeast Mexico.

Latent autoimmune diabetes in adults (LADA) has clinical and metabolic features of type 1 and type 2 diabetes. LADA does not have specific features for its diagnosis apart from autoantibody detection; however, these tests are not affordable in clinical settings. In this cross-sectional study, we analyzed clinical criteria, metabolic control, pharmacological treatment, and diabetic complications in two groups of patients with diabetes -LADA and T2D- in order to identify specific characteristic of these clinical entities. Finally, we evaluated if the estimated glucose disposal rate (eGDR) and age at diagnosis of diabetes could be used as a diagnostic criterion for LADA. Demographic, biochemical, clinical and treatment were measured in 377 individuals with diabetes. The diagnostics of LADA were determined using Glutamic acid decarboxylase autoantibodies levels. Chi-square test or t-Student test were used to establish differences between groups. To identify factors associated with LADA, a logistic regression analysis was used. Finally, a ROC curve was plotted to assess the possible variables as diagnostic criteria for LADA. The 377 patients with diabetes were separated into 59 patients with LADA and 318 patients with T2D. Patients with LADA showed lower fasting glucose values, fewer diabetic complications, younger age at diagnosis of diabetes, higher insulin use, and higher eGDR in comparison to patients with T2D. Both groups had a mean BMI classified as overweight. The ROC evaluated the sensitivity and specificity, this analysis indicated that an age younger than 40.5 years and an eGDR value higher than 9.75 mg/kg/min correlated better with LADA. These parameters could be useful to identify patients suspected to have LADA at the first level of medical care in the population of southeastern Mexico and refer them to a second level of care.

Screening for Brain Injury Sustained in the Context of Intimate Partner Violence (IPV): Measure Development and Preliminary Utility of the Brain Injury Screening Questionnaire IPV Module.

Abstract Intimate partner violence (IPV) is associated with risk for multi-etiology brain injury (BI), including repetitive head impacts, isolated traumatic brain injuries (TBI), and anoxic/hypoxic injury secondary to nonfatal strangulation (NFS). IPV-related injuries are often unreported, but evidence suggests that survivors are more likely to report when asked directly. There are currently no validated tools for screening of brain injury related to IPV that meet World Health Organization guidelines for this population. Here, we describe measure development methods and preliminary utility of the Brain Injury Screening Questionnaire IPV (BISQ-IPV) module. We culled items from existing IPV and TBI screening tools and sought two rounds of stakeholder feedback regarding content coverage, terminology, and safety of administration. The resulting stakeholder-informed BISQ-IPV module is a seven-item self-report measure that uses contextual cues (e.g., being shoved, shaken, strangled) to query lifetime history of IPV-related head/neck injury. We introduced the BISQ-IPV module into the Late Effects of TBI (LETBI) study to investigate rates of violent and IPV-specific head/neck injury reporting in a TBI sample. Among those who completed the BISQ-IPV module (n = 142), 8% of the sample (and 20% of women) reported IPV-related TBI, and 15% of the sample (34% of women) reported IPV-related head or neck injury events that did not result in loss or alteration of consciousness. No men reported NFS; one woman reported inferred BI secondary to NFS, and 6% of women reported NFS events. Those who endorsed IPV-BI were all women, many were highly educated, and many reported low incomes. We then compared reporting of violent TBIs and head/neck injury events among individuals who completed the core BISQ wherein IPV is not specifically queried (administered from 2015-2018; n = 156) to that of individuals who completed the core BISQ preceded by the BISQ-IPV module (BISQ+IPV, administered from 2019-2021; n = 142). We found that 9% of those who completed the core BISQ reported violent TBI (e.g., abuse, assault), whereas 19% of those who completed the BISQ+IPV immediately preceding the core BISQ reported non-IPV-related violent TBI on the core BISQ. These findings suggest that standard TBI screening tools are inadequate for identifying IPV-BI and structured cueing of IPV-related contexts yields greater reporting of both IPV- and non-IPV-related violent BI. When not queried directly, IPV-BI remains a hidden variable in TBI research studies.

Simultaneous enzyme production, Levan-type FOS synthesis and sugar by-products elimination using a recombinant Pichia pastoris strain expressing a levansucrase-endolevanase fusion enzyme.

BACKGROUND: Although Levan-type fructooligosaccharides (L-FOS) have been shown to exhibit prebiotic properties, no efficient methods for their large-scale production have been proposed. One alternative relies on the simultaneous levan synthesis from sucrose, followed by endolevanase hydrolysis. For this purpose, several options have been described, particularly through the synthesis of the corresponding enzymes in recombinant Escherichia coli. Major drawbacks still consist in the requirement of GRAS microorganisms for enzyme production, but mainly, the elimination of glucose and fructose, the reaction by-products. RESULTS: The expression of a fusion enzyme between Bacillus licheniformis endolevanase (LevB1) and B. subtilis levansucrase (SacB) in Pichia pastoris cultures, coupled with the simultaneous synthesis of L-FOS from sucrose and the elimination of the residual monosaccharides, in a single one-pot process was developed. The proof of concept at 250 mL flask-level, resulted in 8.62 g of monosaccharide-free L-FOS and 12.83 gDCW of biomass, after 3 successive sucrose additions (30 g in total), that is a 28.7% yield (w L-FOS/w sucrose) over a period of 288 h. At a 1.5 L bioreactor-level, growth considerably increased and, after 59 h and two sucrose additions, 72.9 g of monosaccharide-free L-FOS and 22.77 gDCW of biomass were obtained from a total of 160 g of sucrose fed, corresponding to a 45.5% yield (w L-FOS/w sucrose), 1.6 higher than the flask system. The L-FOS obtained at flask-level had a DP lower than 20 fructose units, while at bioreactor-level smaller oligosaccharides were obtained, with a DP lower than 10, as a consequence of the lower endolevanase activity in the flask-level. CONCLUSION: We demonstrate here in a novel system, that P. pastoris cultures can simultaneously be used as comprehensive system to produce the enzyme and the enzymatic L-FOS synthesis with growth sustained by sucrose by-products. This system may be now the center of an optimization strategy for an efficient production of glucose and fructose free L-FOS, to make them available for their application as prebiotics. Besides, P. pastoris biomass also constitutes an interesting source of unicellular protein.

Nasal High-Flow for Weaning Preterm Newborns with Risk of Chronic Lung Disease from nCPAP.

OBJECTIVE: The aim of the study is to compare the duration of oxygen therapy by using two methods of weaning from nasal continuous positive airway pressure (nCPAP) in very preterm babies. STUDY DESIGN: Between April 2014 and December 2016, 90 preterm <32 weeks and birthweight >1,000 g who, after at least 7 days on nCPAP, were clinically stable on <6 cm H2O and FiO2 <30% were randomly assigned to weaning directly from nCPAP or with nasal high flow therapy (nHFT). In the nCPAP group, pressure was gradually reduced until the infant was stable on 4 cm H2O and then discontinued. In the nHFT group, flow rate was reduced until the infant was stable at 3.l pm and then discontinued. RESULTS: Eighty-four infants completed the study. There were no differences between the groups for the primary outcome, duration of oxygen therapy (median 33 [14-48] versus 28 [15-37] days; p = 0.17). The incidence of moderate-to-severe bronchopulmonary dysplasia was similar. Weaning time was shorter in the nCPAP group (p = 0.02), but the failure rate was slightly higher although non-significant. In the nHFT group, we observed better perception of patient comfort and a lower incidence of severe nasal injury. CONCLUSION: Weaning by nHFT compared with weaning directly off nCPAP does not prolong duration of oxygen therapy. Rather, it is associated with better perceptions of infant comfort among parents and lower rates of severe nasal injury. KEY POINTS: · Nasal high-flow therapy is commonly used in most neonatal intensive care unit for nCPAP weaning.. · Weaning by nHFT does not increase the duration of oxygen therapy.. · nHFT use improves the perception of infant comfort among parents..

Approach to the Chemotaxonomic Characterization of Traditional Cultivation Grape Varieties through Their Varietal Aroma Profile.

In this study, the aroma profile of 12 minority grape varieties of Vitis vinifera L., included in the 'Caiño group', was defined along three vintages by solid phase microextraction followed by the gas chromatography-mass spectrometry method (SPME-GC-MS). Principal objectives were to assess the aromatic profile as a useful fingerprint to differentiate them, recover traditionally cultivated grape varieties for the differentiation of an important wine-growing area and discover their chemotaxonomic potential. In each variety, free and bound volatile profile was carried out by grouping varietal compounds into thirteen families. In total, 339 volatile compounds were identified, 230 as free forms and 205 as aromatic precursors. Remarkable quantitative differences were observed between aromatic profiles for terpenes in the free fraction and for C6 compounds, alcohols, sesquiterpenes and phenols in the glycosidic fraction. Principal component analysis based on their aromatic profile highlights a good differentiation between varieties and suggests a certain degree of aromatic chemotaxonomic proximity between previously known parental varieties, 'Caiño Blanco' with respect to 'Caiño Bravo' and 'Albariño'. This study shows the preliminary results of a large research project involving a larger number of grape varieties and thus a broader spectrum of genetic relationships between them.

Use of high flow nasal cannula in Spanish neonatal units.

INTRODUCTION: The use of high-flow cannula therapy (HFNC) in neonatal units has increased in recent years, but there are no consensus guidelines on its indications and application strategies. Our aim was to know the rate of use of HFNC, their indications and the management variability among Spanish neonatal units. MATERIAL AND METHODS: Twenty-five-question survey for medical and nursing staff. Level II and III units were contacted by phone and sent in Google forms between September 2016 and December 2018. RESULTS: Ninety-seven responses (63.9% medical, 36.1% nursing), from 69 neonatal units representing 15 autonomous communities (87% level of care III; 13% level II). All units except one have HFNC with a humidified and heated system. Their most frequent indications are: non-invasive ventilation weaning (79.4%), bronchiolitis (69.1%), respiratory distress of the term newborn (58.8%), after extubation (50.5%). Minimum flow (1-5 L/min) and maximum flow (5-15 L/min) are variable between units. 22.7% have experienced some adverse effect from its use (9 air leak, 12 nasal trauma). Less than half have an employment protocol, but all the answers agree on the usefulness of national recommendations. CONCLUSIONS: HFNC therapy is widely used in Spanish units, but there is great variability in its indications and strategies of use. National recommendations would be applicable in most units and would allow unifying its use.

Anthocyanin profile of Galician endangered varieties. A tool for varietal selection.

Polyphenolic characterization of minority red grapevine varieties is a key factor to improve varietal recovery and promotion. This work focuses on determining phenolic family content and anthocyanin (AN) profiles of 28 different red grape varieties during 2018 and 2019 vintages in Galicia (Northwest of the Iberian Peninsula). Most of these varieties are considered "minority varieties" in this region. Additionally, the relationships between the AN groups of compounds were calculated. AN, flavanols, flavonols, hydroxycinnamic acids and stilbenes were extracted, identified, and quantified by High Performance Liquid Chromatography (HPLC). The results show that the phenolic, and more specifically the AN profile, are useful elements for varietal classification. 'Castañal', 'Ferrón', 'Espadeiro' and 'Sousón' stood out because of their content in AN and copigment substances. These varieties differed from the rest of the grape varieties under analysis due to their higher percentages of petunidin and delphinidin derivatives forms. They also had acceptable values of titratable acidity. Since these minority varieties present highly appreciated polyphenolic and acidity characteristics, they should be recommended to be grown in Galicia.

Effect of two preservation methods on the viability and enzyme production of a recombinant Komagataella phaffii (Pichia pastoris) strain.

The methylotrophic yeast Komagataella phaffii, previously known as Pichia pastoris, has been reported as a host for producing human recombinant lysosomal enzymes intended for enzyme replacement therapy. K. phaffii has advantages such as easy genetic handling, rapid growth, cost-effective mediums, and the ability to develop mammalian-like post-translational modifications. To maintain cell viability and enzyme activity over time, it is important to consider the bioprocess optimization and the proper selection and preservation of clones. In this study, we evaluated the effect of glycerol and skim milk in cryopreservation at -80 °C, as well as the use of skim milk or its combination with NaCl, disaccharides or sorbitol in freeze-drying on the cell viability and activity of a recombinant lysosomal enzyme (i.e., human ß-hexosaminidase-A) produced in K. phaffii GS115 strain. The results showed that cryopreservation with glycerol and skim milk, as well as freeze-drying using disaccharides and sorbitol with skim milk, maintained the viability above 80%. Although variations in enzyme activity among treatments were found, the use of disaccharides had a positive effect on the enzymatic activity levels. This is the first report of the evaluation of two suitable methods to preserve a recombinant K. phaffii strain, preventing the loss of viability and maintaining the activity of the recombinant protein.

Non-Anthocyanin Compounds in Minority Red Grapevine Varieties Traditionally Cultivated in Galicia (Northwest Iberian Peninsula), Analysis of Flavanols, Flavonols, and Phenolic Acids.

Non-anthocyanin compounds (NAN) such as flavonol, flavanol, and phenolic acids should be considered in the characterization of minority red grapevine varieties because these compounds are involved in copigmentation reactions and are potent antioxidants. Sixteen NAN were extracted, identified, and quantified by High Performance Liquid Chromatography (HPLC) from grapes of 28 red genotypes of Vitis vinifera L. grown in Galicia (Northwest of Spain) in 2018 and 2019 vintages. The percentage of total NAN with respect to the total polyphenol content (TPC) values was calculated for each sample and established into three categories: high percentage NAN varieties (NANV), those varieties showing low percentages of NAN (ANV), and finally those varieties showing medium percentages of NAN (NANAV). 'Xafardán' and 'Zamarrica', classified as NANAV, had high values of TPC and showed good percentages of flavonol and flavanol compounds. Principal component analyses (PCA) were performed with flavonol, flavanol, and phenolic acid profiles. The flavonol and flavanol profiles allowed a good discrimination of samples by variety and year, respectively. The flavonol profile should therefore be considered as a potential varietal marker. The results could help in the selection of varieties to be disseminated and in the identification of the most appropriate agronomic and oenological techniques that should be performed on them.

eHealth and mHealth Development in Spain: Promise or Reality?

In the last decades, the use of Information and Communication Technologies (ICTs) has progressively spread to society and public administration. Health is one of the areas in which the use of ICTs has more intensively developed through what is now known as eHealth. That area has recently included mHealth. Spanish health system has stood out as one of the benchmarks of this technological revolution. The development of ICTs applied to health, especially since the outbreak of the pandemic caused by SARS Cov-2, has increased the range of health services delivered through smartphones and the development of subsequent specialized apps. Based on the data of a Survey on Use and Attitudes regarding eHealth in Spain, the aim of this research was to conduct a comparative analysis of the different eHealth and mHealth user profiles. The results show that the user profile of eHealth an mHealth services in Spain is not in a majority. Weaknesses are detected both in the knowledge and use of eHealth services among the general population and in the usability or development of their mobile version. Smartphones can be a democratizing vector, as for now, access to eHealth services is only available to wealthy people, widening inequality.

Potential applications of recombinant bifidobacterial proteins in the food industry, biomedicine, process innovation and glycobiology.

Bifidobacterial proteins have been widely studied to elucidate the metabolic mechanisms of diet adaptation and survival of Bifidobacteria, among others. The use of heterologous expression systems to obtain proteins in sufficient quantities to be characterized has been essential in these studies. L. lactis and the same Bifidobacterium as expression systems highlight ways to corroborate some of the functions attributed to these proteins. The most studied proteins are enzymes related to carbohydrate metabolism, particularly glycosidases, due to their potential application in the synthesis of neoglycoconjugates, prebiotic neooligosaccharides, and active metabolites as well as their high specificity and efficiency in processing glycoconjugates. In this review, we classified the recombinant bifidobacterial proteins reported to date whose characterization has demonstrated their usefulness or their ability to produce a product of commercial interest for the food industry, biomedicine, process innovation and glycobiology. Future directions for their study are also discussed. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s10068-021-00957-1.

Physical activity, diet, and weight loss in patients recruited from primary care settings: An update on obesity management interventions.

BACKGROUND: Obesity and related comorbidities are the most common chronic conditions in North America where behavior modification including the adoption of physical activity (PA) and a healthful diet are primary treatment strategies. Patients are more likely to engage in behavior modification if encouraged by their physician; however, behavioral counseling in primary care rarely occurs due to lack of training and resources. A more effective method may be to refer patients from clinical settings to other health professionals. OBJECTIVE: This systematic review examines the effectiveness of behavior-based counseling for obesity management among participants referred from clinical settings. METHODS: PubMed, CINAHL, and EMBASE were used to identify randomized clinical trials (2014-2020) for weight loss with the following inclusion criteria: trial duration ≥12 months, included a control or usual care group, recruited adults with overweight or obesity from primary care and/or treated in the primary care setting, and the intervention included counseling on PA and diet. RESULTS: Seventeen studies, encompassing 21 different intervention groups with 6185 unique participants (56% female) met the inclusion criteria. All participants had overweight or obesity, with a body mass index between 28.2 and 41.0 kg/m2. In 11 (52%) of the intervention groups, significant weight loss in the intervention group was observed compared to usual care (mean weight loss: 4.9[2.1] kg vs. 1.0[0.9] kg). In 13 out of 18 interventions (72%) reporting weight loss at two time points, weight regain was observed by 12 months. Statistically significant weight loss was observed in one intervention (of two total) that was longer than 12 months. CONCLUSIONS: Sustained weight loss regardless of the behavior-based, intervention strategy remains a challenge for most adults. Given the established benefits of routine PA and a healthful diet, prioritizing the adoption of healthy behaviors regardless of weight loss may be a more effective strategy for ensuring long-term health benefit.

An atypical case of congenital lobar emphysema in an adult, non-smoker patient presenting with pneumothorax.

Congenital lobar emphysema (CLE) is a developmental anomaly of the lower respiratory tract characterized by hyperinflation of one or more pulmonary lobes in the absence of extrinsic bronchial obstruction. We present a case of a 24-year-old male, nonsmoker who presented with shortness of breath and severe left sided chest pain. A chest x-ray was significant for a very large left-sided pneumothorax and chest CT showed lobar emphysematous changes. Video assisted thoracoscopic surgery (VATS) and lobectomy was subsequently performed after persistence of pneumothorax despite chest tube insertion and conservative management. Surgical pathology of resected specimen showed chronic emphysematous changes with patchy chronic organizing pneumonitis. Histology showed advanced emphysematous changes of pulmonary parenchyma consistent with congenital lobar emphysema. This finding combined with features seen on computed tomography of the chest led to the diagnosis of congenital lobar emphysema. This case demonstrated that CLE can be a cause of tension pneumothorax in adults in rare cases.
