RESUMO
PURPOSE: One-anastomosis-gastric-bypass (OAGB) has become a common bariatric procedure worldwide. Marginal ulcers (MU) are a significant non-immediate complication of gastric bypass surgeries. There seems to be concern among surgeons that MU are more common after OAGB compared with Roux-en-Y gastric bypass (RYGB) due to the constant and extensive exposure of the anastomosis to bile. The aim of this study was to compare the incidence, presentation, and management of MU between the two surgeries. MATERIALS AND METHODS: A retrospective study of prospectively collected data was performed to include all consecutive patients between 2010 and 2020, who underwent elective OAGB or RYGB at our institution. Patients diagnosed with symptomatic MU were identified. Factors associated with this complication were assessed and compared between the two surgeries. RESULTS: Symptomatic MU were identified in 23/372 OAGB patients (6.2%) and 35/491 RYGB patients (7.1%) (p = 0.58). Time to ulcer diagnosis was shorter in OAGB patients (12 ± 11 vs. 22 ± 17 months, p < 0.01). Epigastric pain was the common symptom (78% OAGB vs. 88.5% RYGB, p = 0.7) and approximately 15% of ulcers presented with perforation upon admission (17% vs.11.4%, p = 0.7). Re-operation was required in 5/23 OAGB (21.7%) and 6/36 RYGB (17%) patients (p = 0.11) while the rest of the patients were managed non-operatively. CONCLUSIONS: The risk of developing a marginal ulcer is similar between patients who underwent OAGB and RYGB. Patients diagnosed with MU following OAGB tend to present earlier; however, the clinical presentation is similar to RYGB patients. The management of this serious complication seems to be associated with acceptable outcomes with comparable operative and non-operative approaches.

BACKGROUND: The COVID-19 pandemic created new challenges and barriers for the work of child protection professionals (CPPs) and intensified existing hardships for families and children, increasing the risk of child maltreatment. As new restrictions and precautions were implemented by governments worldwide to stop the virus from spreading, CPPs had to adapt to a new reality of working remotely. However, limited research has investigated how remote work impacted CPPs and child protection work and how CPPs handled this alternative work style. OBJECTIVE: This review aims to address gaps in the research to reveal the creative and effective approaches CPPs developed to overcome the challenges presented by COVID-19, defined as the 'positive legacy' of CPPs, particularly in adapting to remote work challenges. METHOD: This review was conducted using a scoping review, followed by two rounds of thematic analysis. The scoping review was conducted in six languages: Hebrew, Arabic, French, Portuguese, Spanish, and English. RESULTS: The first round of thematic analysis found 18 articles relevant to this review. The second round extracted two main themes: 1) the challenges of remote work and 2) overcoming the challenges of no contact. CONCLUSIONS: The findings of this review may be used to inform future strategies for child protection during a pandemic. They also provide an opportunity to rethink the relationship child protection work has with technology to systematically reform current and future protection policies and practices, including outside of a pandemic.
RESUMO
The COVID-19 pandemic has led to high global demand for vaccines to safeguard public health. To that end, our institute has developed a recombinant viral vector vaccine utilizing a modified vesicular stomatitis virus (VSV) construct, wherein the G protein of VSV is replaced with the spike protein of SARS-CoV-2 (rVSV-ΔG-spike). Previous studies have demonstrated the production of a VSV-based vaccine in Vero cells adsorbed on Cytodex 1 microcarriers or in suspension. However, the titers were limited by both the carrier surface area and shear forces. Here, we describe the development of a bioprocess for rVSV-ΔG-spike production in serum-free Vero cells using porous Fibra-Cel® macrocarriers in fixed-bed BioBLU®320 5p bioreactors, leading to high-end titers. We identified core factors that significantly improved virus production, such as the kinetics of virus production, the use of macrospargers for oxygen supply, and medium replenishment. Implementing these parameters, among others, in a series of GMP production processes improved the titer yields by at least two orders of magnitude (2e9 PFU/mL) over previously reported values. The developed process was highly effective, repeatable, and robust, creating potent and genetically stable vaccine viruses and introducing new opportunities for application in other viral vaccine platforms.
RESUMO
BACKGROUND: The COVID-19 pandemic challenged child protection and posed new risks for child maltreatment (CM). Moreover, governmental efforts worldwide prioritized mitigating the spread of the virus over ensuring the welfare and protection of families and children. This neglect caused hardship for many vulnerable children, including those in out-of-home care (OOHC), and challenged the functionality of child protective services (CPS). However, only limited research has investigated the impact of COVID-19 on OOHC and CPS and explored how CPS overcame the challenges of helping children in OOHC. OBJECTIVE: This review aims to address this gap in the research to unveil the 'positive legacy' left by CPS in their work with children in OOHC during COVID-19. METHOD: This review utilized three stages of analysis, including a scoping review followed by two rounds of thematic analysis. The scoping review was carried out in six languages: English, Hebrew, Arabic, French, Portuguese, and Spanish. The first round of thematic analysis found eight relevant articles for this review. The second round of thematic analysis found three themes related to this paper's aim in the context of COVID-19. RESULTS: Three main themes were identified: 1) decision-making and OOHC, 2) difficulties in procedures related to OOHC placement, and 3) handling challenges of OOHC. CONCLUSIONS: The discussion emphasizes the crucial role of preserving children's rights, hearing their voices and needs, and considering their safety and well-being when planning policies and practices to protect them. It also emphasizes society's responsibility to acknowledge contextual factors in child protection.
RESUMO
Psychological resilience, the ability to adapt to adversity, is theorized to rely on intact inhibitory control (IC) mechanisms, which underlie one's ability to maintain goal-directed behavior by inhibiting prepotent responses. However, no study to date has explored daily fluctuations of IC performance in relation to resilience. Here, we examined the association between IC and mood measured daily in relation to psychological resilience in young adults in a stressful situation. Baseline resilience was obtained from 144 female and male soldiers during their basic combat training. Then, participants completed an ecological momentary assessment protocol, in which they reported their momentary mood and completed a short IC assessment twice/day for 2 weeks. A hierarchical linear modeling analysis revealed that psychological resilience moderated the relationship between momentary IC and momentary mood, such that better IC was associated with better mood only for those with higher, but not lower, self-reported psychological resilience at baseline. These results show that psychological resilience is manifested in the everyday association between IC and mood. Furthermore, they lend important support to cognitive models of resilience and may have significant contribution to our understanding of resilient behavior in real life.Trial Registration: MOH_2018-0-13_002451.

BACKGROUND: The COVID-19 pandemic triggered new risks for child maltreatment (CM) and exacerbated existing challenges for families and children, elevating the importance of child protection professionals (CPPs) while also adding barriers to their work. During the pandemic, many CPPs experienced increased workloads, a disrupted work environment, and personal pandemic-related hardships. However, the scope of how COVID-19 impacted CPPs globally, as well as their adopted coping strategies, have not been well explored. OBJECTIVE: This study addresses these gaps in the research by conducting an international scoping review to explore and analyze these topics. METHOD: The scoping review was performed in six languages: English, Hebrew, Arabic, French, Spanish, and Portuguese, across 16 databases. Sixteen manuscripts were included in the final thematic analysis of this review. RESULTS: Two main themes were identified: 1) the impact of COVID-19 on CPPs, and 2) the coping and adaptation strategies employed by CPPs during COVID-19. This review revealed and emphasized the importance of CPPs' resilience during COVID-19, underpinned by the theoretical framework of the social ecology of resilience. CONCLUSIONS: This study highlights the responsibility of social ecologies and organizational structures to create readiness for a rapid response in times of crisis as well as valuable evidence to inform how CPPs, children, and families may be better supported in the event of a future crisis.
RESUMO
BACKGROUND: Sibling bonds are often the most enduring relationship in an individual's life span. The out-of-home placement of siblings is widespread and may significantly influence children's journeys and wellbeing. OBJECTIVE: The current scoping literature review was designed to characterize and analyze the existing knowledge regarding siblings in out-of-home placements. METHOD: Key databases were explored using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, which identified 33 studies relevant to the current study's focus. The studies used quantitative, qualitative, and mixed methods and included a variety of out-of-home placement settings and sample characteristics. RESULTS: Utilizing thematic analysis, the findings addressed three main themes: the sibling bond as a contributor to the wellbeing of children in out-of-home placements, trends in sibling placement, and difficulties in maintaining the sibling bond in out-of-home placements regarding micro, meso and exo factors. CONCLUSION: A key conclusion from the review is that the welfare system struggles to address a child as a part of a sibling group and an extensive and multilayered relational network; hence, siblinghood is an unutilized resource in out-of-home placements. Future directions for practice, policy and research are included and discussed.

The following paper proposes a combination of a supervised encoder-decoder neural network with coded apertures. Coded apertures provide improved sensitivity and signal-to-noise ratio (SNR) in planar images. The unique array design of this method overcomes the spatial frequency cutoff found in standard multi-pinhole arrays. In this design, the pinholes were positioned to minimize loss in spatial frequencies. The large number of pinholes results in significant overlapping on the detector. To overcome the overlapping issue, reconstruction of the object from the obtained image is done using inverse filtering methods. However, traces of duplications remain leading to a decline in SNR, contrast, and resolution. The proposed technique addresses the challenge of image distortion caused by the lack of accuracy in the inverse filter methods, by using a deep neural network. In this work, the coded aperture is combined with a deep convolutional neural network (CNN) to remove noise caused by pinhole imaging and inverse filter limitations. Compared to only using Wiener filtering, the proposed method delivers higher SNR, contrast, and resolution. The imaging system is presented in detail with experimental results that illustrate its efficiency.
RESUMO
OBJECTIVE: Empirical literature on child sexual abuse (CSA) has traditionally focused on the CSA of girls. Much less is known about the CSA of boys, specifically about the survivors' experiences. The current study was designed to examine the experiences and perceptions of male adult survivors who underwent CSA as boys. METHOD: Fifty-one written narratives were collected from survivors who experienced CSA as boys as part of the Israeli Independent Public Inquiry into CSA. A qualitative inductive thematic analysis guided the data analysis. RESULTS: The findings highlighted CSA survivors' experiences of not understanding and confusion about the abuse while highlighting the context in which the abuse took place. The findings also emphasized the exploitation of power and the survivors' difficulty identifying being sexually abused during physical fights or public events. Moreover, the survivors referred to their surroundings' failure to notice the abuse and their struggle to establish their identity and overcome the abuse consequences, their loneliness and pain. CONCLUSION: The present findings advance the literature on the CSA of boys by examining narratives written by male CSA survivors. They highlight the potentially destructive role of the heteronormative and conventional masculinity discourse for male CSA survivors, which often enabled the continuation of abuse and challenges that survivors continued to face throughout their lives. The findings also stress society's crucial role in CSA prevention and treatment and the need for public education to challenge societal perceptions regarding the CSA of boys.

BACKGROUND: The Israel Defense Force is the only military organisation in the world that mandatorily conscripts women since its founding. Despite legislative changes, the percentage of women serving as combat soldiers is low, and the dropout rate is high. Women in these professions experience a complex and unique adaptation process. AIMS: To characterise the experiences of female combat soldiers adjusting to combat roles in comparison with male soldiers and non-warfighter female soldiers. METHOD: A pilot study was undertaken in order to inform further research. Mental health officers in the women's units conducted group interviews. These were composed of four stages: projection, reflection, processing and formulating solutions. RESULTS: The themes apparent in the interviews conform to phenomena appearing in the literature such as tokenism, disruption of gender identity and internalisation of the superiority of male values. In addition, we identified distortion of body image and increased burnout. DISCUSSION AND CONCLUSIONS: The study points to the significance of gender aspects in the mental adaptation process of women in combat positions. Issues pertaining perceptions of inequality should not be deemed to be purely sociological, but rather as a gateway facilitating adjustment. This should be taken into account in future research and in the formulation of support strategies.

The COVID-19 pandemic has had a far-ranging impact. As societies struggled to minimize infection, questions arose regarding the consequences for children. Initial research reported the urgent need for child protective services worldwide to adapt existing policies and practices to protect children from maltreatment during this time, which is the rationale for the current systematic literature review. This review examined studies published in peer-reviewed journals from March 2020 to October 2020 on child maltreatment (CM) in the context of COVID-19. Twenty-five manuscripts met the inclusion criteria and were predominantly from the United States, with three international studies. The majority of the studies included CM reports during COVID-19 based on official data. The results clearly demonstrated an increased risk for children alongside a worrisome international decrease in CM reports. Only two studies addressed interventions during the pandemic. The current review highlights that, along with the obligation of scholars to advance the protection of children during COVID-19, there is much that is unknown. Future studies should examine the impact of the pandemic on children and their surrounding systems as well as child protective services' responses, which face enormous challenges during a pandemic. An additional conclusion is that, since children were not identified as a health risk group during the pandemic, their protection rights may have been jeopardized. Furthermore, the variance identified in the policies of different countries pinpoints the urgent need to establish an international protocol for protecting children from maltreatment during COVID-19, a protocol that will hopefully be a basis for policymakers worldwide.

There is a worldwide consensus that the prevention of child maltreatment (CM) is critical in promoting children's safety. Furthermore, a significant part of the prevention efforts targets the children themselves. This scoping review aimed to map the characteristics of CM prevention programs that targeted children by examining studies that described the relevant implemented programs, published in peer-reviewed journals over the last decade. Thirty-one relevant manuscripts were identified from the online databases. The analysis, guided by scoping review guidelines, examined these programs in terms of content, context of delivery, and practitioners involved. A thematic analysis identified the key messages conveyed to the children. The findings showed that the vast majority of programs are school-based and focused on preventing child sexual abuse (CSA) with considerably less attention given to other forms of maltreatment. In addition, most programs did not promote active parental participation. The content descriptions of the CSA prevention programs revealed several common key messages that focused on children's individual safety skills, specifically recognition, refusal strategies, and disclosure. The discussion addresses the concepts of blame and guilt as crucial to rethinking the CM prevention messages conveyed to children. Key conclusions that were drawn from the current scoping review highlight the need to better align prevention efforts and recent CM research. Additionally, ceiling effects in several studies indicated that children's participation, as information sources and partners in program development, should be promoted, so that prevention efforts will meet their needs within their various relevant life contexts.

BACKGROUND: Forensic interviews for children who have undergone online sexual solicitation (OSS) constitute a unique setting compared to other forms of child sexual abuse (CSA). In these cases, the interviewer holds concrete evidence of the abuse in the form of pictures or texts. During the interview, interviewers use these materials to advance the data collection regarding the abuse, a practice that may significantly influence the child's wellbeing. OBJECTIVE: The current study aims to explore children's experiences during forensic interviews concerning OSS. PARTICIPANTS AND SETTING: The sample included 20 Jewish children in Israel who were referred to and participated in a forensic investigation. METHODS: A thematic qualitative methodology was used to analyze the children's narratives. RESULTS: The findings demonstrate the children's difficulties when confronted with materials related to the abuse. The children detailed the different ways the interview challenged their wellbeing, including visualizing and verbalizing the abuse, new insights, and being videotaped. CONCLUSIONS: The findings in the current study emphasized the intrinsic challenges that children face in OSS forensic interviews resulting from the tension between the interviewer's need to collect details about the abuse and the child's desire to forget it. Practical ramifications pertaining to these threats to the child's wellbeing, future recommendations, and limitations of the study will be discussed.

BACKGROUND: Drug resistance continues to be a major limiting factor across diverse anti-cancer therapies. Contributing to the complexity of this challenge is cancer plasticity, in which one cancer subtype switches to another in response to treatment, for example, triple-negative breast cancer (TNBC) to Her2-positive breast cancer. For optimal treatment outcomes, accurate tumor diagnosis and subsequent therapeutic decisions are vital. This study assessed a novel approach to characterize treatment-induced evolutionary changes of distinct tumor cell subpopulations to identify and therapeutically exploit anticancer drug resistance. METHODS: In this research, an information-theoretic single-cell quantification strategy was developed to provide a high-resolution and individualized assessment of tumor composition for a customized treatment approach. Briefly, this single-cell quantification strategy computes cell barcodes based on at least 100,000 tumor cells from each experiment and reveals a cell-specific signaling signature (CSSS) composed of a set of ongoing processes in each cell. RESULTS: Using these CSSS-based barcodes, distinct subpopulations evolving within the tumor in response to an outside influence, like anticancer treatments, were revealed and mapped. Barcodes were further applied to assign targeted drug combinations to each individual tumor to optimize tumor response to therapy. The strategy was validated using TNBC models and patient-derived tumors known to switch phenotypes in response to radiotherapy (RT). CONCLUSIONS: We show that a barcode-guided targeted drug cocktail significantly enhances tumor response to RT and prevents regrowth of once-resistant tumors. The strategy presented herein shows promise in preventing cancer treatment resistance, with significant applicability in clinical use.

Bacillus subtilis biofilms are well known for their complex and highly adaptive morphology. Indeed, their phenotypical diversity and intra-biofilm heterogeneity make this gram-positive bacterium the subject of many scientific papers on the structure of biofilms. The "robustness" of biofilms is a term often used to describe their level of susceptibility to antimicrobial agents and various mechanical and molecular inhibition/eradication methods. In this paper, we use computational analytics to quantify Bacillus subtilis morphological response to proximity to an antimicrobial source, in the form of the antiseptic chlorhexidine. Chlorhexidine droplets, placed in proximity to Bacillus subtilis macrocolonies at different distances result in morphological changes, quantified using Python-based code, which we have made publicly available. Our results quantify peripheral and inner core deformation as well as differences in cellular viability of the two regions. The results reveal that the inner core, which is often characterized by the presence of wrinkled formations in the macrocolony, is more preserved than the periphery. Furthermore, the paper describes a crescent-shaped colony morphology which occurs when the distance from the chlorhexidine source is 0.5 cm, as well as changes observed in the growth substrate of macrocolonies exposed to chlorhexidine.

BACKGROUND: Alongside deficits in children's wellbeing, the COVID-19 pandemic has created an elevated risk for child maltreatment and challenges for child protective services worldwide. Therefore, some children might be doubly marginalized, as prior inequalities become exacerbated and new risk factors arise. OBJECTIVE: To provide initial insight into international researchers' identification of children who might have been overlooked or excluded from services during the pandemic. PARTICIPANTS AND SETTING: This study was part of an international collaboration involving researchers from Brazil, Canada, Colombia, Israel, South Africa, Uganda, the UK and the USA. Researchers from each country provided a written narrative in response to the three research questions in focus, which integrated the available data from their countries. METHOD: Three main questions were explored: 1) Who are the children that were doubly marginalized? 2) What possible mechanisms may be at the root? and 3) In what ways were children doubly marginalized? The international scholars provided information regarding the three questions. A thematic analysis was employed using the intersectional theoretical framework to highlight the impact of children's various identities. RESULTS: The analysis yielded three domains: (1) five categories of doubly marginalized children at increased risk of maltreatment, (2) mechanisms of neglect consisting of unplanned, discriminatory and inadequate actions, and (3) children were doubly marginalized through exclusion in policy and practice and the challenges faced by belonging to vulnerable groups. CONCLUSION: The COVID-19 pandemic can be used as a case study to illustrate the protection of children from maltreatment during worldwide crises. Findings generated the understanding that child protective systems worldwide must adhere to an intersectionality framework to protect all children and promote quality child protection services.

BACKGROUND: A year has passed since COVID-19 began disrupting systems. Although children are not considered a risk population for the virus, there is accumulating knowledge regarding children's escalating risk for maltreatment during the pandemic. OBJECTIVE: The current study is part of a larger initiative using an international platform to examine child maltreatment (CM) reports and child protective service (CPS) responses in various countries. The first data collection, which included a comparison between eight countries after the pandemic's first wave (March-June 2020), illustrated a worrisome picture regarding children's wellbeing. The current study presents the second wave of data across 12 regions via population data (Australia [New South Wales], Brazil, United States [California, Pennsylvania], Colombia, England, Germany, Israel, Japan, Canada [Ontario, Quebec], South Africa). METHOD: Regional information was gathered, including demographics, economic situation, and CPS responses to COVID-19. A descriptive analysis was conducted to provide an overview of the phenomenon. RESULTS: Across all of the countries, COVID-19 had a substantial negative impact on the operation of CPSs and the children and families they serve by disrupting in-person services. One year into the COVID-19 pandemic, new reports of CM varied across the regions.1 In some, the impact of COVID-19 on CPS was low to moderate, while in others, more significant changes created multiple challenges for CPS services. CONCLUSIONS: COVID-19 created a barrier for CPS to access and protect children. The dramatic variance between the regions demonstrated how social, economic and structural contexts impact both CM reports and CPS responses.

ObjectivesSense of mastery, a well-recognized resource for older adults, has been shown to be related to early life experiences, especially parent-child interactions. Yet while there are indications that a reduced sense of mastery is related to early experiences of child maltreatment, this association has not been studied among older adults. The aim of this study was to examine the relation between experiences of childhood parental invalidation and sense of mastery among older adults, through the mediation of self-objectification and perceived disrupted body boundaries.Methods: Three-hundred-and-sixteen older adults (Mean = 72.24; SD = 8.12 years; range: 60-94) filled out a battery of questionnaires assessing their levels of exposure to childhood parental invalidation experiences, sense of self-objectification, disrupted body boundaries, and sense of masteryResults: A structural equation modeling (SEM) analysis supported the hypothesized research model. More specifically, two significant indirect effects were observed, according to which the association between invalidating childhood experiences and sense of mastery was mediated by both self-objectification and by disrupted body boundaries.Conclusion: As these results suggest that early life experiences continue to affect individuals' sense of self in older age, they should be considered an important factor for evaluation and intervention.

RNA-binding proteins (RBPs) play a key role in post-transcriptional regulation via binding to coding and non-coding RNAs. Recent development in experimental technologies, aimed to identify the targets of RBPs, has significantly broadened our knowledge on protein-RNA interactions. However, for many RBPs in many organisms and cell types, experimental RNA-binding data is not available. In this chapter we describe a computational approach, named RBPmap, available as a web service via http://rbpmap.technion.ac.il/ and as a stand-alone version for download. RBPmap was designed for mapping and predicting the binding sites of any RBP within a nucleic acid sequence, given the availability of an experimentally defined binding motif of the RBP. The algorithm searches for a sub-sequence that significantly matches the RBP motif, considering the clustering propensity of other weak matches within the motif environment. Here, we present different applications of RBPmap for discovering the involvement of RBPs and their targets in a variety of cellular processes, in health and disease states. Finally, we demonstrate the performance of RBPmap in predicting the binding targets of RBPs in large-scale RNA-binding data, reinforcing the strength of the tool in distinguishing cognate binding sites from weak motifs.
