Unlocking Overexpressed Membrane Proteins to Guide Breast Cancer Precision Medicine.

Breast cancer (BC) is a prevalent form of cancer affecting women worldwide. However, the effectiveness of current BC drugs is limited by issues such as systemic toxicity, drug resistance, and severe side effects. Consequently, there is an urgent need for new therapeutic targets and improved tumor tracking methods. This study aims to address these challenges by proposing a strategy for identifying membrane proteins in tumors that can be targeted for specific BC therapy and diagnosis. The strategy involves the analyses of gene expressions in breast tumor and non-tumor tissues and other healthy tissues by using comprehensive bioinformatics analysis from The Cancer Genome Atlas (TCGA), UALCAN, TNM Plot, and LinkedOmics. By employing this strategy, we identified four transcripts (LRRC15, EFNA3, TSPAN13, and CA12) that encoded membrane proteins with an increased expression in BC tissue compared to healthy tissue. These four transcripts also demonstrated high accuracy, specificity, and accuracy in identifying tumor samples, as confirmed by the ROC curve. Additionally, tissue microarray (TMA) analysis revealed increased expressions of the four proteins in tumor tissues across all molecular subtypes compared to the adjacent breast tissue. Moreover, the analysis of human interactome data demonstrated the important roles of these proteins in various cancer-related pathways. Taken together, these findings suggest that LRRC15, EFNA3, TSPAN13, and CA12 can serve as potential biomarkers for improving cancer diagnosis screening and as suitable targets for therapy with reduced side effects and enhanced efficacy.

Academic Half Day Improves Resident Perception of Education Without Compromising Patient Safety.

BACKGROUND: Residency programs are required to offer a didactic curriculum and protect resident time for education. Our institution implemented an academic half day (AHD) in the 2021-2022 academic year to address issues related to the standard noon conference series. OBJECTIVE: Determine the impact of AHD implementation on education, patient safety, and workflow. METHODS: This was a prospective, single-site educational intervention study. Pre- and post-implementation surveys and Accreditation Council for Graduate Medical Education (ACGME) surveys assessed changes in trainee and faculty attitudes and behaviors. Patient safety and workflow were evaluated by comparing the number of safety event reports, rapid response team activations, time to admission from the ED, and time of discharge on AHD days compared to other weekdays. RESULTS: Survey response rates were: residents 68%/48%, fellows 42%/35%, and faculty 59%/29%. AHD was associated with a significant, positive change in resident attitudes and experiences and on ACGME survey items. On AHDs compared with other weekdays, there were no significant differences in safety event report rates (P = .98), nor in rapid response team activation rates (P = .99). There was not a clinically meaningful difference in median admission time from the ED on AHD weekdays (125 minutes) compared to other weekdays (130 minutes, P = .04). There was no significant difference in median discharge time on AHD vs other weekdays (P = .13). CONCLUSIONS: This study suggests that there is no significant difference in patient safety or workflow with the implementation of AHD. This study supports prior studies that residents strongly prefer AHD. AHD may be a useful framework for resident education without compromising patient care.

Process evaluation of a parent-child communication intervention for adolescent sexual and reproductive health in Uganda.

BACKGROUND: Previous initiatives concerning adolescent sexual and reproductive health (SRH) education in Low-or-Middle Income Countries (LMICs) have been limited by cultural norms and misinformation perpetuated within families. Responding to the paucity of research on the implementation of SRH interventions in LMICs and limited knowledge regarding their mechanisms, this study undertakes a process evaluation of a parent-focused intervention to promote parent-adolescent communication about SRH in Uganda. METHODS: This paper explores the implementation, contextual factors and mechanisms of impact of the intervention, using the Medical Research Council (MRC) guidelines for process evaluations. Implementation was evaluated through indicators of dose, fidelity and adaptations, acceptability and feasibility. The contextual factors and mechanisms of impact were evaluated to refine the intervention's causal assumptions. Data was collected during April - October 2021 in South-Western Uganda using a mixed-methods approach, including document analysis, intervention observations, interviews, focus group discussions and most significant change stories. RESULTS: The acceptability of the intervention was related to its community engagement, the strong rapport with delivery agents, and individual characteristics of participants. Five contextual factors influencing implementation were highlighted; (i) cultural norms, (ii) perceptions about youth SRH, (iii) poverty, (iv) Covid-19 pandemic, and (v) prior research projects in the community. When considering the intervention's mechanisms of impact, four causal pathways were identified; (i) Awareness of SRH needs helped parents overcome stigma, (ii) Parenting skills training improved SRH communication, (iii) Group learning stimulated shared parenting, and (iv) Group learning improved co-parenting. CONCLUSION: The paper presented three key learnings and corresponding recommendations for future research. Firstly, implementation success was credited to meaningful community engagement which improved acceptability and uptake. Secondly, the complex influences of contextual factors highlighted the need for contextual analysis in research studies to inform intervention design. Finally, this evaluation recognised the interplay between mechanisms of impact and suggested further research consider such combined impacts when designing intervention content.

Experiences of a mobile phone delivered brief intervention for hazardous drinking: A qualitative study nested in the AMBIT trial from Goa, India.

Background: This study explores the experiences of participants receiving a mobile-based brief intervention (BI) for hazardous drinking in India, to determine characteristics that influenced engagement and examine perceived reasons for change in alcohol consumption. Methods: Semi-structured interviews were conducted with 10 adult hazardous drinkers who received a mobile-based BI in the intervention arm of a pilot randomised control trial. Data were coded through an iterative process and analysed using thematic analysis. Findings: Study participants reported a positive experience, with factors such as customised intervention delivery and personal motivation facilitating their engagement. Participants reported a reduction in quantity and frequency of alcohol use. This was credited to the intervention, particularly, its provision of health-related information, goal-setting content and strategies to manage drinking. Apart from alcohol reduction, participants reported improvements in diet, lifestyle, wellbeing, and familial relations. Implication: By providing a context to explain the impact of the intervention, the learnings from this study can be used to strengthen the implementation of mobile-based interventions. This study outlines the scope for further research in digital health, such as Internet-based health interventions, and incorporating digital interventions within the ambit of existing health care programmes.

Caregiver Perspectives on Social Needs Screening and Interventions in an Urban Children's Hospital.

OBJECTIVES: Caregiver opinions of inpatient social needs screening and ways of addressing positive screens are not well understood. We aimed to explore caregiver perspectives and goals surrounding inpatient screening and determine how helpful provided resources are at meeting these goals. METHODS: We conducted a qualitative study using semistructured interviews with caregivers of pediatric patients admitted to an urban tertiary care children's hospital from April to August 2021. English- and Spanish-speaking caregivers who screened positive for at least 1 social need on a standardized 10-item questionnaire were invited to participate in an interview 2 to 4 months after discharge. Interviews were recorded, transcribed, and analyzed by 2 independent coders using rapid qualitative methods. RESULTS: We completed 20 interviews, with 14 English-speaking and 6 Spanish-speaking caregivers. Four themes emerged: (1) All caregivers expressed support for inpatient social needs screening. (2) Many caregivers cited it as an effective means to support families and help providers better understand their social situation. (3) Caregivers who recalled receiving a resource packet found it useful and at times even shared the resources with others. (4) The majority of caregivers expressed interest in longitudinal support, such as contact after discharge. CONCLUSIONS: Caregivers are in support of inpatient screening as a means for providers to optimize comprehensive care that explores how unmet social needs influence health. Although inpatient social work and resource packets may be helpful, longitudinal support after discharge may improve the effectiveness of social needs interventions, patient outcomes, and caregiver satisfaction.

Trends and Challenges in Comprehensive Sex Education (CSE) Research in Sub-Saharan Africa: a Narrative Review.

Purpose of the Review: Adolescent sexual and reproductive health remains a major public health challenge in Sub-Saharan Africa (SSA). Comprehensive sex education (CSE) has been hailed as a key strategy to inform young people about sexual health and wellbeing and prevent negative health outcomes. This paper presents an overview of the trends and challenges around sex education in SSA and puts forth key recommendations for future research and policy initiatives. Recent Findings: This review employed a narrative approach to synthesize evidence on the implementation of comprehensive sex education in SSA. The literature review elicited four key themes: (i) comprehensiveness of CSE curricula, (ii) gender norms in CSE, (iii) prominence of 'fear' narratives in CSE implementation, and (iv) CSE delivery methods. Additionally, the authors propose a fifth theme-'Future-proofing CSE programs', based on their learnings from implementing sex education interventions during the COVID-19 pandemic. These five themes are presented through a narrative description of current research accompanied by reflections from the authors on the implementation of a parent-focused sex education program in Uganda. Summary: Based on the insights from the literature review and the authors' reflections, three recommendations are put forward to guide the design of further CSE initiatives: (i) stakeholder engagement in determining CSE priorities and strategies, (ii) diverse delivery pathways for CSE programs, and (iii) active engagement of both boys and girls to challenge gender norms in CSE.

Narratives of most significant change to explore experiences of caregivers in a caregiver-young adolescent sexual and reproductive health communication intervention in rural south-western Uganda.

BACKGROUND: This paper presents findings from a qualitative effectiveness evaluation of an intervention aimed at improving caregiver-young adolescent sexual and reproductive health (SRH) communication including training modules for caregivers on parent-child SRH communication. METHODS: Data was collected (October 2021-November 2021) using a narrative interviewing technique with thirty caregivers (8 males and 22 females), who received the parent-child communication intervention in Mbarara district, south-western Uganda. We explored caregivers' experiences with the intervention based on four domains of change: caregiver-young adolescent communication on SRH issues, knowledge and attitudes towards adolescent SRH, parenting skills, and personal life and family. Thematic analysis was used to code and analyse the data, with attention to gender differences. RESULTS: Findings highlight positive parenting as a key attribute of SRH communication, along with a transformation of knowledge and attitudes towards the SRH of young adolescents leading to an overall improvement in SRH communication. However, communication is still limited to comfortable topics. CONCLUSION: Our findings indicate improved caregiver-adolescent SRH communication practices following a community intervention. Programming for adolescent health on broader sexuality topics, comfortability and attitude change among caregivers could promote behaviour change on a long term. Future studies may focus on the long term impacts of interventions of this nature and test interventions aimed at addressing comfortability with discussingSRH issues.

Exploring the Link between Oil Exploitation and Cancer in the Indigenous Population of Ecuador: A Scoping Review.

With cancer accounting for 19% of deaths and projected to rise in the coming years, Ecuador's inequities in healthcare coverage remain a major concern for the rural, indigenous populations. While the cancer burden among this vulnerable population has been much publicized in the context of the controversial oil extraction in the Amazon, there is contradictory evidence on its occurrence and determinants. This review critically discusses the available literature on cancer among indigenous people in Ecuador and explores the link between oil exploitation and cancer occurrence among indigenous people using a scoping review approach. The results of this review show there is a clear but inconsistent association between oil exposure and cancer risk in indigenous populations of Ecuador. While the environmental magnitude of oil extraction in this region is a topic of debate, our findings point to the interplay with social determinants and other sources of carcinogenic compounds, which exacerbates the risks faced by indigenous communities. Based on these findings, this study puts forward three arguments to contextualize the occurrence of cancer related to oil exploitation in the Amazon, and puts forth key recommendations for public health initiatives embedded within the local community.

Brief intervention for hazardous drinking delivered using text messaging: a pilot randomised controlled trial from Goa, India.

OBJECTIVE: To evaluate the feasibility and acceptability of a mobile-based brief intervention (BI), generate preliminary estimates of the impact of the BI and fine-tune the procedures for a definitive randomised controlled trial. DESIGN: Parallel three-arm single-blind individually randomised controlled pilot trial. Eligible and consenting participants were randomised to receive mobile-based BI, face-to-face BI and information leaflet. SETTING: Educational institutions, workplaces and primary care centres. PARTICIPANTS: Adult hazardous drinkers. RESULTS: Seventy-four participants were randomised into the three trial arms; forty-eight (64·9 %) completed outcome evaluation. There were no significant differences between the three arms on change in any of the drinking outcomes. There were however in two-way comparisons. Face-to-face BI and mobile BI were superior to active control for percent days heavy drinking at follow-up, and mobile BI was superior to active control for mean grams ethanol consumed per week at follow-up. CONCLUSION: The encouraging findings about feasibility and preliminary impact warrant a definitive trial of our intervention and if found to be effective, our intervention could be a potentially scalable first-line response to hazardous drinking in low-resource settings.

Factors Associated With Hospitalization in Children and Adolescents With SARS-CoV-2 Infection.

In this retrospective study of 319 children with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, we assessed whether age, asthma, obesity, diabetes, and socioeconomic status were associated with hospitalization for coronavirus disease 2019 (COVID-19). Demographic and clinical characteristics were assessed using univariate statistics, excluding incidental or unrelated positives. There was a bimodal distribution of age among hospitalized children. Obesity (P < .001) and a past medical history of diabetes (P = .001) were significantly more prevalent in hospitalized children, including cases of new-onset diabetes and diabetic ketoacidosis. Neither a past medical history of asthma nor lower socioeconomic status was associated with hospitalization. Although limited to a single center, the findings in this study may have important clinical implications. Targeted, proactive health outreach to children with obesity and diabetes, with prioritization of preventative efforts such as vaccination, may be important in preventing worse SARS-CoV-2 infection in this vulnerable group.

Video-augmentation of the informed consent process in mental health research: An exploratory study from India.

Only around 50-75% of individuals fully understand the various aspects of informed consent in research. The aim of our study was to examine whether supplementing the conventional paper-based informed consent process with an audiovisual aid improves participants' understanding of the informed consent process and the information conveyed to them. Participants from two mental health/substance use intervention development studies were recruited for this study through consecutive sampling. They were then administered the traditional paper information and consenting process by itself or in combination with a video depicting the procedures of the study. Subsequently a bespoke questionnaire was administered to assess the participants' understanding of the information conveyed to them about the parent study. The various domains of the questionnaire were compared between those who were administered the two different consenting processes using the chi square test. 27 (58.7%) participants were administered the traditional consenting process and 19 were administered the video-supplemented consenting process. The video-supplemented consenting process was not superior to the traditional paper-based informed consent process on any of the domains examined. In settings with participants having a limited education, and in research involving people with mental health or substance use problems, further research is necessary to identify contextually relevant best practices for the informed consent process.

Effects of photobiomodulation therapy on functional recovery, angiogenesis and redox status in denervated muscle of rats.

OBJECTIVE: To evaluate the effects of photobiomodulation therapy in redox status, angiogenesis marker - vascular endothelial growth factor - and in the functional recovery in denervated muscle. METHODS: A total of 32 female Wistar rats underwent a crush injury and were randomly divided into four groups: Light Emitting Diode Group 2 and Control Group 2 (muscle collected 2 days after injury), and Light Emitting Diode Group 21 and Control Group 21 (muscle collected 21 days afterinjury). Light Emitting Diode Group 2 and Light Emitting Diode Group 21 received two and ten light emitting diode applications (630±20nm, 9J/cm2, 300mW), respectively, and the Control Group 2 and Control Group 21 did not receive any treatment. The function was evaluated by grasping test at four moments (pre-injury, 2, 10 and 21 post-injury days). The flexor digitorum muscle was collected for analysis of immunolocalization of vascular endothelial growth factor and redox parameters. RESULTS: Functional improvement was observed at the second and tenth post-injury day in treated groups compared to control (p<0.005). The muscle tissue of treated groups presented higher immunohistochemical expression of vascular endothelial growth factor. Photobiomodulation therapy decreased the oxidative damage to lipid in Light Emitting Diode Group 2 compared to Control Group 2 (p=0.023) in the denervated muscle. CONCLUSION: Photobiomodulation therapy accelerated the functional recovery, increased angiogenesis and reduced lipid peroxidation in the denervated muscle at 2 days after injury.

Global Overview of Youth Development: Comparison of the 5 Cs and Developmental Assets Across Six Countries.

Positive Youth Development (PYD) frameworks which describe young people's strengths and their relation to thriving and risk outcomes have gained significance among developmental researchers globally. As these models are being increasingly adopted, concerns remain about their generalizability outside of North America. It has been observed that the distribution and salience of assets differ for young people based on their cultural context. To better understand these varying developmental patterns, this paper studies the distribution of developmental assets and 5 Cs (Competence, Confidence, Character, Caring, and Connection) in youth from various countries and contrasting backgrounds. The total sample consisted of 4,175 students (62.5% females) with age ranging from 15 to 25 years (M = 18.95, SD = 2.49). 981 students were from Ghana (52.5% females), 900 students from Kosovo (66.7% females), 425 students from Norway (73.5% females), 247 students from Portugal (42.1% females), 648 students from Slovenia (63.4% females,), and 974 students from Turkey (68.7% females). Before comparisons of the countries, partial scalar invariance was confirmed. Analyses revealed that all countries differed in at least some internal or external developmental assets and at least in one of the 5 Cs. When considering internal assets, participants from Ghana seemed to have higher levels of internal assets together with participants from Norway who have the highest commitment to learning. Slovenian youth reported the highest levels of external assets of support and empowerment. Regarding the 5 Cs, Ghanaian youth reported having the highest confidence and character, and youth from Ghana, Kosovo, and Turkey are more caring and connected to others. The results uncovered unique patterns of PYD for each included country which are discussed through the lens of its political and social context. Through this focus on cross-national PYD patterns, this study advanced knowledge about the experiences of youth from a wide range of backgrounds and put forth suggestions for better policy measures and more culturally relevant interventions for optimal development of youth embedded in different cultures and countries.

The systematic development of a mobile phone-delivered brief intervention for hazardous drinking in India.

BACKGROUND: The treatment gap for alcohol use disorders (AUD) in India is the highest among all mental health and substance use disorders. Despite evidence of the cost effectiveness of brief interventions (BIs) for hazardous drinking, implementation in low- and middle-income countries (LMICs) is rare due to several human resource-related barriers. This paper describes the processes and outputs of a study aimed at systematically developing a mobile phone-delivered BI to overcome such barriers. METHODS: This is a mixed methods study with four steps: (1) Review of existing relevant evidence base by extracting data from studies cited in two recent, relevant and high-quality systematic reviews; (2) In-depth interviews (IDIs) with 11 national experts in addictions research and practice, and 22 hazardous drinkers; (3) Delphi survey (2 rounds) to identify components for the intervention package through consensus building; and (4) Content and intervention development workshops with a range of stakeholders to develop the intervention package. RESULTS: The research team sourced 72 journal articles from two selected systematic reviews. Key content areas extracted from the studies included facts and statistics about health related to drinking behavior, self-reflection, goal-setting messages, motivational messages, and skills to manage risky situations. The IDIs with experts and hazardous drinkers endorsed most of these content areas as well. The Delphi survey achieved consensus on 19 content areas, which included targeted recommendations, personalized feedback and information, goal management, and coping skills. The content and intervention development workshops resulted in an intervention package delivered over 8 weeks, with the following seven themes guiding the content of the weekly messages: safe drinking/health education, alcohol reduction, drinking and risk management, drinking alternatives, situational content, urge management, and maintenance and relapse prevention. CONCLUSION: The research team designed this study to consider contextual factors while developing the intervention, which is important to ensure acceptability and feasibility of the intervention. Interestingly, the contextually informed intervention components had several commonalities with BIs developed and tested in high-income countries.

Severe Acute Respiratory Syndrome Coronavirus 2 Clinical Syndromes and Predictors of Disease Severity in Hospitalized Children and Youth.

OBJECTIVE: To characterize the demographic and clinical features of pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) syndromes and identify admission variables predictive of disease severity. STUDY DESIGN: We conducted a multicenter, retrospective, and prospective study of pediatric patients hospitalized with acute SARS-CoV-2 infections and multisystem inflammatory syndrome in children (MIS-C) at 8 sites in New York, New Jersey, and Connecticut. RESULTS: We identified 281 hospitalized patients with SARS-CoV-2 infections and divided them into 3 groups based on clinical features. Overall, 143 (51%) had respiratory disease, 69 (25%) had MIS-C, and 69 (25%) had other manifestations including gastrointestinal illness or fever. Patients with MIS-C were more likely to identify as non-Hispanic black compared with patients with respiratory disease (35% vs 18%, P = .02). Seven patients (2%) died and 114 (41%) were admitted to the intensive care unit. In multivariable analyses, obesity (OR 3.39, 95% CI 1.26-9.10, P = .02) and hypoxia on admission (OR 4.01; 95% CI 1.14-14.15; P = .03) were predictive of severe respiratory disease. Lower absolute lymphocyte count (OR 8.33 per unit decrease in 109 cells/L, 95% CI 2.32-33.33, P = .001) and greater C-reactive protein (OR 1.06 per unit increase in mg/dL, 95% CI 1.01-1.12, P = .017) were predictive of severe MIS-C. Race/ethnicity or socioeconomic status were not predictive of disease severity. CONCLUSIONS: We identified variables at the time of hospitalization that may help predict the development of severe SARS-CoV-2 disease manifestations in children and youth. These variables may have implications for future prognostic tools that inform hospital admission and clinical management.

Effects of photobiomodulation therapy on functional recovery, angiogenesis and redox status in denervated muscle of rats / Efeitos da terapia de fotobiomodulação na recuperação funcional, na angiogênese e no estado redox em músculo desnervado de ratos

ABSTRACT Objective: To evaluate the effects of photobiomodulation therapy in redox status, angiogenesis marker - vascular endothelial growth factor - and in the functional recovery in denervated muscle.

RESUMO Objetivo: Avaliar os efeitos da terapia de fotobiomodulação no estado redox, no marcador de angiogênese - fator de crescimento endotelial vascular - e na recuperação funcional do músculo desnervado. Métodos: Um total de 32 ratas Wistar foi submetido a uma lesão por esmagamento e dividido aleatoriamente em quatro grupos: Grupo Diodo Emissor de Luz 2 e Grupo Controle 2 (músculo coletado 2 dias após a lesão), além do Grupo Diodo Emissor de Luz 21 e do Grupo Controle 21 (músculo coletado 21 dias após a lesão). Grupo Diodo Emissor de Luz 2 e Grupo Diodo Emissor de Luz 21 receberam duas e dez aplicações de diodo emissor de luz (630±20nm, 9J/cm2e 300mW), respectivamente, e Grupo Controle 2 e Grupo Controle 21 não receberam tratamento. A função foi avaliada pelo teste de preensão em quatro momentos (pré-lesão, 2, 10 e 21 dias após a lesão). O músculo flexor dos dedos foi coletado para análise dos parâmetros redox e da imunolocalização do fator de crescimento endotelial vascular. Resultados: Houve melhora funcional no segundo e décimo dia pós-lesão nos grupos tratados em comparação aos controles (p<0,005). O tecido muscular dos grupos tratados apresentou maior expressão imuno-histoquímica do fator de crescimento endotelial vascular. A terapia de fotobiomodulação diminuiu o dano oxidativo aos lipídeos no Grupo Diodo Emissor de Luz 2 comparado ao Grupo Controle 2 (p=0,023) no músculo desnervado. Conclusão: A terapia de fotobiomodulação acelerou a recuperação funcional, aumentou a angiogênese e reduziu a peroxidação lipídica no músculo desnervado 2 dias após a lesão.
