Quality of life, perceived stress and caregiver burden in mothers of children with childhood psychiatric disorders in Kerala, India
Background: Common childhood psychiatric problems like attention deficit hyperkinetic disorder (ADHD), Pervasive developmental disorder (PDD) and learning disability (LD) often co-exists with each other and form a constellation of behavioural manifestations that require extra attention from the caregivers. Having a differentially-abled child is challenging and most parents have to learn to restructure their lives around that of the child. There is a difference in the attitudes of both the parents as far as parenting a disabled child is concerned. Mothers often shoulder the primary caregiving role however the psychological costs borne by women go unrecognized. The study aims to assess the care giver burden (BOC) and perceived stress (PS) and quality of life (QOL) in mothers of children with ADHD, PDD and LD.Methods: It was a cross-sectional study with 336 child mother pairs. The mothers were asked to rate their burden and stress symptoms on the perceived stress scale and Burden of care scale. The mothers were also asked to rate their quality of life on the quality of life scale.Results: The mean PS score was highest in the PDD group. The mean BOC was lowest in the LD group. The QOL score was highest in the LD group. There is statistically significant difference in the PS, BOC and QOL scores among the three groups.Conclusions: There is a hidden lacuna of psychological stress in mothers of children with common psychiatric problems. The study also establishes that these mothers have poorer quality of life. It is necessary to address these psychological issues of the mother at every visit and equip them with coping strategies so that they can look after both themselves and their special needs child
What predicts wellbeing amidst crisis? A study of promotive and protective psychological factors among Malaysians during the COVID-19 pandemic
Resilience promotes psychological growth and buffers against the effects of negative events, but the factors that promote optimal wellbeing beyond resilience remain poorly understood. The current study addresses this gap through a positive psychology perspective by examining how (i) promotive factors – optimism and hope, and (ii) protective factors – nostalgia and spirituality promote wellbeing. We hypothesized that both factors will be positively related to wellbeing above and beyond that predicted by resilience. A representative sample of six hundred and twenty-six (n = 626; M age = 32.66, SD = 10.11, 43.45% female) Malaysians responded to an online survey at the end of the country’s second wave of the COVID-19 pandemic (June-September 2020). We conducted a series of regression analyses, controlling for resilience, socio-economic status, age, and perceptions towards government crisis management efforts. Results indicate that optimism and hope positively predicted wellbeing above and beyond that predicted by resilience. Results also showed that the only significant protective factor contributing to wellbeing is spirituality. Nostalgia did not significantly predict wellbeing beyond resilience. The findings are of theoretical relevance for wellbeing and resilience research, and practically beneficial in informing mental health interventions
\u3ci\u3eIn Vivo\u3c/i\u3e Selection To Identify Bacterial Strains with Enhanced Ecological Performance in Synbiotic Applications
One strategy for enhancing the establishment of probiotic bacteria in the human intestinal tract is via the parallel administration of a prebiotic, which is referred to as a synbiotic. Here we present a novel method that allows a rational selection of putative probiotic strains to be used in synbiotic applications: in vivo selection (IVS). This method consists of isolating candidate probiotic strains from fecal samples following enrichment with the respective prebiotic. To test the potential of IVS, we isolated bifidobacteria from human subjects who consumed increasing doses of galactooligosaccharides (GOS) for 9 weeks. A retrospective analysis of the fecal microbiota of one subject revealed an 8-fold enrichment in Bifidobacterium adolescentis strain IVS-1 during GOS administration. The functionality of GOS to support the establishment of IVS-1 in the gastrointestinal tract was then evaluated in rats administered the bacterial strain alone, the prebiotic alone, or the synbiotic combination. Strain-specific quantitative real-time PCR showed that the addition of GOS increased B. adolescentis IVS-1 abundance in the distal intestine by nearly 2 logs compared to rats receiving only the probiotic. Illumina 16S rRNA sequencing not only confirmed the increased establishment of IVS-1 in the intestine but also revealed that the strain was able to outcompete the resident Bifidobacterium population when provided with GOS. In conclusion, this study demonstrated that IVS can be used to successfully formulate a synergistic synbiotic that can substantially enhance the establishment and competitiveness of a putative probiotic strain in the gastrointestinal tract

Kailo: a systemic approach to addressing the social determinants of young people’s mental health and wellbeing at the local level [version 1; peer review: awaiting peer review]
The mental health and wellbeing of children and young people is deteriorating. It is increasingly recognised that mental health is a systemic issue, with a wide range of contributing and interacting factors. However, the vast majority of attention and resources are focused on the identification and treatment of mental health disorders, with relatively scant attention on the social determinants of mental health and wellbeing and investment in preventative approaches. Furthermore, there is little attention on how the social determinants manifest or may be influenced at the local level, impeding the design of contextually nuanced preventative approaches. This paper describes a major research and design initiative called Kailo that aims to support the design and implementation of local and contextually nuanced preventative strategies to improve children's and young people’s mental health and wellbeing. The Kailo Framework involves structured engagement with a wide range of local partners and stakeholders - including young people, community partners, practitioners and local system leaders - to better understand local systemic influences and support programmes of youth-centred and evidence-informed co-design, prototyping and testing. It is hypothesised that integrating different sources of knowledge, experience, insight and evidence will result in better embedded, more sustainable and more impactful strategies that address the social determinants of young people’s mental health and wellbeing at the local level
A Case Series Exploration of Multi-Regional Expression Heterogeneity in Triple-Negative Breast Cancer Patients
Background: Extensive intratumoral heterogeneity (ITH) is believed to contribute to therapeutic failure and tumor recurrence, as treatment-resistant cell clones can survive and expand. However, little is known about ITH in triple-negative breast cancer (TNBC) because of the limited number of single-cell sequencing studies on TNBC. In this study, we explored ITH in TNBC by evaluating gene expression-derived and imaging-derived multi-region differences within the same tumor. Methods: We obtained tissue specimens from 10 TNBC patients and conducted RNA sequencing analysis of 2-4 regions per tumor. We developed a novel analysis framework to dissect and characterize different types of variability: between-patients (inter-tumoral heterogeneity), between-patients across regions (inter-tumoral and region heterogeneity), and within-patient, between-regions (regional intratumoral heterogeneity). We performed a Bayesian changepoint analysis to assess and classify regional variability as low (convergent) versus high (divergent) within each patient feature (TNBC and PAM50 subtypes, immune, stroma, tumor counts and tumor infiltrating lymphocytes). Results: Gene expression signatures were categorized into three types of variability: between-patients (108 genes), between-patients across regions (183 genes), and within-patients, between-regions (778 genes). Based on the between-patient gene signature, we identified two distinct patient clusters that differed in menopausal status. Significant intratumoral divergence was observed for PAM50 classification, tumor cell counts, and tumor-infiltrating T cell abundance. Other features examined showed a representation of both divergent and convergent results. Lymph node stage was significantly associated with divergent tumors. Conclusions: Our results show extensive intertumoral heterogeneity and regional ITH in gene expression and image-derived features in TNBC. Our findings also raise concerns regarding gene expression based TNBC subtyping. Future studies are warranted to elucidate the role of regional heterogeneity in TNBC as a driver of treatment resistance
Cytokine and Protein Markers of Leprosy Reactions in Skin and Nerves: Baseline Results for the North Indian INFIR Cohort
Leprosy affects skin and peripheral nerves. Although we have effective antibiotics to treat the mycobacterial infection, a key part of the disease process is the accompanying inflammation. This can worsen after starting antibacterial treatment with episodes of immune mediated inflammation, so called ‘reactions’. These reactions are associated with worsening of the nerve damage. We recruited a cohort of 303 newly diagnosed leprosy patients in North India with the aim of understanding and defining the pathological processes better. We took skin and nerve biopsies from patients and examined them to define which molecules and mediators of inflammation were present. We found high levels of the cytokines Tumour Necrosis Factor alpha, Transforming Growth Factor beta and inducible Nitric Oxide Synthase in biopsies from patients with reactions. We also found high levels of bacteria and inflammation in the nerves. These experiments tell us that we need to determine which other molecules are present and to explore ways of switching off the production of these pro-inflammatory molecules
Analysis of Antibody and Cytokine Markers for Leprosy Nerve Damage and Reactions in the INFIR Cohort in India
Leprosy is one of the oldest known diseases. In spite of the established fact that it is least infectious and a completely curable disease, the social stigma associated with it still lingers in many countries and remains a major obstacle to self reporting and early treatment. The nerve damage that occurs in leprosy is the most serious aspect of this disease as nerve damage leads to progressive impairment and disability. It is important to identify markers of nerve damage so that preventive measures can be taken. This prospective cohort study was designed to look at the potential association of some serological markers with reactions and nerve function impairment. Three hundred and three newly diagnosed patients from north India were recruited for this study. The study attempts to reflect a model of nerve damage initiated by mycobacterial antigens and maintained by ongoing inflammation through cytokines such as Tumour Necrosis Factor alpha and perhaps extended by antibodies against nerve components
Prophets vs. profits: How market competition influences leaders' disciplining behavior towards ethical transgressions
We investigate how market competition influences the way organizational leaders discipline moral transgressions of employees. In a cross-sectional study among organizational leaders at various hierarchical levels (Study 1), we find that strong market competition is related to an instrumental decision frame (business practices being perceived as focused on serving the organization’s interest). This decision frame explains why strong market competition is related to leaders’ perceptions of the evaluation of wrongdoing in terms of instrumental rather than moral concerns. In two subsequent experiments (Study 2 and 3), we find that high (relative to low) market competition makes leaders’ disciplining of moral transgressions contingent upon the instrumentality of the transgression to the organization. We find that the same transgression is punished less severely when it resulted in profit for the organization than when it resulted in loss. This research is among the first to identify conditions that determine the disciplinary responses of organization leaders to employees’ moral transgressions, and it feeds the debate on whether market competition - a fundamental characteristic of capitalist economies - promotes the display of moral or immoral behavior within organization
