RESUMEN

The pervasive Catholic culture permeates through the social fabric of the Philippines and exerts unique pressures on Filipinos. This study highlighted the unique experiences of Filipino LGBTQ+ educators of private Catholic schools. Using the grounded theory approach, seven participants who identified as LGBTQ+ and taught in private Catholic schools in the Philippines for a minimum of one year were interviewed. Semi-structured interviews with the participants illustrated that these LGBTQ+ educators had to contend with negotiating their identities while carefully navigating through their work environment. This yielded three key themes: (1) Recognizing the political dimension of private schools, (2) Threading the Needle, and (3) Obtaining and Optimizing Safe Spaces. As a result, the Constricting Contexts Model was proposed to better understand and contextualize such factors and emphasize the role that environments and expectations play into the identities of marginalized groups such as the LGBTQ+ community.

RESUMEN

Telehealth looks to be a viable tool to meet patients' expectations and requirements during home treatment; however, there are obstacles to overcome. Palliative care has been described as 'high touch' rather than 'high tech', which may restrict healthcare workers' enthusiasm in integrating technological advances into the development and refinement of interventions. As a result, the goal of this integrative review was to map and evaluate existing research on the use of telemedicine and telehealth in palliative care patients during the COVID-19 outbreak. This review was guided using the PRISMA Model and CASP guidelines. A total of 17 articles on the use of telehealth in palliative care satisfied the inclusion and exclusion criteria of the review. This integrative review provided more evidence for the function and application of telehealth in palliative care. It demonstrated the resiliency of individuals in swiftly adjusting to a new system or application and the adaptability of healthcare systems and providers in establishing an alternate means of providing treatment to patients during a crisis.

RESUMEN

High levels of vaccine hesitancy are an obstacle to the successful management of the Covid-19 pandemic. In this research, we identify psychological correlates of reluctance to personally receive a Covid-19 vaccine, with a focus on intergroup relations. Insights are based on two survey studies conducted in traditionally underresearched settings, the Philippines (N = 289) and Pakistan (N = 275). Results show that trust in vaccines, concerning both the vaccine's efficacy and the vaccine's safety, was associated with willingness to use the vaccine. Perceptions of trust were related to intergroup psychology, such that vaccine donations from political opponents rather than allies were trusted less. This meant that in the Philippines, there was a preference to use vaccines from the United States over those from China, although the pattern was less clear in Pakistan. Having said this, the highest levels of trust and willingness to use vaccines in both countries were for vaccines offered by the World Health Organization (WHO). Last but not least, a perception of global common fate of all humans in the face of the pandemic was positively associated with willingness to get vaccinated, even when controlling for concerns about the vaccine's efficacy and safety. Implications are discussed in relation to intergroup psychology and public health management.

RESUMEN

Growing demand for staple crops like rice will need to be achieved predominately through agricultural intensification and more efficient use of inputs. To meet this demand it is essential that the genetic diversity within rice is fully utilized. The aus subpopulation is considered an underappreciated resource within that diversity. A new rice panel, the Bengal and Assam Aus Panel (BAAP) of 266 aus accessions was generated with ∼2 million informative SNPs obtained using skim sequencing at ∼4× depth. The BAAP was grown in the field in Bangladesh in the 'boro' season under both continuously flooded and Alternate Wetting and Drying (AWD) irrigation during 2013 and 2014 in Mymensingh and during 2014 in Madhupur. Heading date, grain mass, straw biomass and harvest index were measured. The majority (94%) of BAAP accessions flowered within a relatively small window of 10 days. The AWD irrigation treatment generally caused an increase in grain mass, but no significant genotype by treatment interactions were detected for this trait. Shoot biomass was the only trait that showed evidence of genotype by treatment interaction. The average LD (Linkage Disequilibrium) decay across the genome was 243 Kbp. Genome wide association mapping revealed 115 quantitative trait loci (QTLs). There was little evidence of QTLs specific to the irrigation treatment, and only a few QTLs co-localized with known genes. However, some QTLs were detected across multiple sites and years. These QTLs should be targets for breeding, and include a region around 2.2 Mbp on chromosome 1, a large region in the middle of chromosome 7 and two regions on chromosome 11 (∼10 Mbp and ∼29 Mbp). The BAAP appears to be a valuable addition to the growing collection of GWA mapping populations of rice.

RESUMEN

BACKGROUND: Insulin resistance disrupts metabolic processes and leads to various chronic disease states such as diabetes and metabolic syndrome (MetS). However, the mechanism linking insulin resistance with cardiometabolic disease pathophysiology is still unclear. One possibility may be through circulating microRNAs (c-miRs), which can alter gene expression in target tissues. Our goal was to assess the relationship of c-miRs with insulin sensitivity, as measured by the gold standard, hyperinsulinemic-euglycemic clamp technique. METHODS: Eighty-one nondiabetic, sedentary, and weight-stable patients across a wide range of insulin sensitivities were studied. Measurements were taken for blood pressure, anthropometric data, fasting glucose and lipids, and insulin sensitivity measured by clamp. After an initial screening array to identify candidate miRs in plasma, all samples were assessed for relationships between these c-miRs and insulin sensitivity, as well as associated metabolic factors. RESULTS: miR-16 and miR-107 were positively associated with insulin sensitivity (R2 = 0.09, P = 0.0074 and R2 = 0.08, P = 0.0417, respectively) and remained so after adjustment with body mass index (BMI). After adjusting for BMI, miR-33, -150, and -222 were additionally found to be related to insulin sensitivity. Regarding metabolic risk factors, miR-16 was associated with waist circumference (r = -0.25), triglycerides (r = -0.28), and high-density lipoprotein (r = 0.22), while miR-33 was inversely associated with systolic blood pressure (r = -0.29). No significant relationships were found between any candidate c-miRs and BMI, diastolic blood pressure, or fasting glucose. CONCLUSIONS: Our results show that relative levels of circulating miR-16, -107, -33, -150, and -222 are associated with insulin sensitivity and metabolic risk factors, and suggest that multiple miRs may act in concert to produce insulin resistance and the clustering of associated traits that comprise the MetS. Therefore, miRs may have potential as novel therapeutic targets or agents in cardiometabolic disease.

RESUMEN

CONTEXT: F2-isoprostanes (F2-isoPs) are biomarkers for oxidative stress in humans and have been shown to be elevated in obesity, cardiovascular disease, and diabetes. Therefore, F2-isoPs are often implicated in oxidative stress contributing to insulin resistance, although this has not been rigorously examined. OBJECTIVE: To determine whether urinary F2-isoPs are predictive of insulin sensitivity and other clinical metabolic parameters. PARTICIPANTS: Sedentary, weight-stable, nondiabetic adults equilibrated on a standard isocaloric diet. MAIN OUTCOME MEASURES: Insulin sensitivity via hyperinsulinemic-euglycemic clamp, urinary F2-isoPs by gas chromatography-mass spectrometry, and body composition by dual-energy x-ray absorptiometry. RESULTS: No correlation was found between 15-F2t-IsoP nor its major metabolite, 2,3-dinor-5,6-dihydro-15-F2t-IsoP, with insulin sensitivity, even after adjusting for age, race, sex, BMI, and smoking status. 15-F2t-IsoP was also not associated with body fat. However, there was a strong negative correlation between 15-F2t-IsoP and lean body mass (LBM; r = -0.46, P = 0.0001), bone mineral content (BMC; r = -0.58, P < 0.0001), bone mineral density (BMD; r = -0.65, P < 0.0001), and skeletal muscle protein 4-hydroxynonenal (4-HNE; r = -0.54, P = 0.0239), another marker of oxidative stress. 15-F2t-IsoP was also positively associated with circulating triglycerides and total cholesterol, and increased as a function of age. CONCLUSIONS: Urinary 15-F2t-IsoP and its major metabolite are not associated with insulin sensitivity, suggesting the lipid peroxidation process that produces F2-isoPs does not reflect oxidative stress reactions operative in insulin resistance. However, urinary F2-isoPs were negatively correlated with LBM, BMC, BMD, and muscle 4-HNE. Because lean and bone mass decline as a function of biological aging, F2-isoPs may reflect the oxidative stress operative in the aging process.

RESUMEN

Markus and Kitayama's (1991) theory of independent and interdependent self-construals had a major influence on social, personality, and developmental psychology by highlighting the role of culture in psychological processes. However, research has relied excessively on contrasts between North American and East Asian samples, and commonly used self-report measures of independence and interdependence frequently fail to show predicted cultural differences. We revisited the conceptualization and measurement of independent and interdependent self-construals in 2 large-scale multinational surveys, using improved methods for cross-cultural research. We developed (Study 1: N = 2924 students in 16 nations) and validated across cultures (Study 2: N = 7279 adults from 55 cultural groups in 33 nations) a new 7-dimensional model of self-reported ways of being independent or interdependent. Patterns of global variation support some of Markus and Kitayama's predictions, but a simple contrast between independence and interdependence does not adequately capture the diverse models of selfhood that prevail in different world regions. Cultural groups emphasize different ways of being both independent and interdependent, depending on individualism-collectivism, national socioeconomic development, and religious heritage. Our 7-dimensional model will allow future researchers to test more accurately the implications of cultural models of selfhood for psychological processes in diverse ecocultural contexts.

RESUMEN

Variations in acquiescence and extremity pose substantial threats to the validity of cross-cultural research that relies on survey methods. Individual and cultural correlates of response styles when using 2 contrasting types of response mode were investigated, drawing on data from 55 cultural groups across 33 nations. Using 7 dimensions of self-other relatedness that have often been confounded within the broader distinction between independence and interdependence, our analysis yields more specific understandings of both individual- and culture-level variations in response style. When using a Likert-scale response format, acquiescence is strongest among individuals seeing themselves as similar to others, and where cultural models of selfhood favour harmony, similarity with others and receptiveness to influence. However, when using Schwartz's (2007) portrait-comparison response procedure, acquiescence is strongest among individuals seeing themselves as self-reliant but also connected to others, and where cultural models of selfhood favour self-reliance and self-consistency. Extreme responding varies less between the two types of response modes, and is most prevalent among individuals seeing themselves as self-reliant, and in cultures favouring self-reliance. As both types of response mode elicit distinctive styles of response, it remains important to estimate and control for style effects to ensure valid comparisons.

RESUMEN

In the current study, we used muscle-specific TRIB3 overexpressing (MOE) and knockout (MKO) mice to determine whether TRIB3 mediates glucose-induced insulin resistance in diabetes and whether alterations in TRIB3 expression as a function of nutrient availability have a regulatory role in metabolism. In streptozotocin diabetic mice, TRIB3 MOE exacerbated, whereas MKO prevented, glucose-induced insulin resistance and impaired glucose oxidation and defects in insulin signal transduction compared with wild-type (WT) mice, indicating that glucose-induced insulin resistance was dependent on TRIB3. In response to a high-fat diet, TRIB3 MOE mice exhibited greater weight gain and worse insulin resistance in vivo compared with WT mice, coupled with decreased AKT phosphorylation, increased inflammation and oxidative stress, and upregulation of lipid metabolic genes coupled with downregulation of glucose metabolic genes in skeletal muscle. These effects were prevented in the TRIB3 MKO mice relative to WT mice. In conclusion, TRIB3 has a pathophysiological role in diabetes and a physiological role in metabolism. Glucose-induced insulin resistance and insulin resistance due to diet-induced obesity both depend on muscle TRIB3. Under physiological conditions, muscle TRIB3 also influences energy expenditure and substrate metabolism, indicating that the decrease and increase in muscle TRIB3 under fasting and nutrient excess, respectively, are critical for metabolic homeostasis.

RESUMEN

Increasing food production is essential to meet the demands of a growing human population, with its rising income levels and nutritional expectations. To address the demand, plant breeders seek new sources of genetic variation to enhance the productivity, sustainability and resilience of crop varieties. Here we launch a high-resolution, open-access research platform to facilitate genome-wide association mapping in rice, a staple food crop. The platform provides an immortal collection of diverse germplasm, a high-density single-nucleotide polymorphism data set tailored for gene discovery, well-documented analytical strategies, and a suite of bioinformatics resources to facilitate biological interpretation. Using grain length, we demonstrate the power and resolution of our new high-density rice array, the accompanying genotypic data set, and an expanded diversity panel for detecting major and minor effect QTLs and subpopulation-specific alleles, with immediate implications for rice improvement.

RESUMEN

BACKGROUND: Insulin resistance is central in the pathophysiology of cardiometabolic disease; however, common mechanisms that explain the parallel development of both type 2 diabetes and atherosclerosis have not been elucidated. We have previously shown that tribbles homolog 3 (TRB3) can exert a chronic pathophysiological role in promoting insulin resistance and also has an acute physiological role to alternatively regulate glucose uptake in fat and muscle during short-term fasting and nutrient excess. Since TRB3 is expressed in human atherosclerotic plaques, we explored its role in foam cell formation to assess its potential contribution to atherogenesis. METHODS: We have used human THP-1 monocytes, which transition to lipid-laden macrophage foam cells when exposed to oxidized low-density lipoprotein (ox-LDL). RESULTS: We first observed that TRB3 was upregulated by more than twofold (P < 0.01) within 24 hr of treatment with ox-LDL. To determine whether TRB3 actively participated in foam cell formation, we overexpressed TRB3 in THP-1 monocytes and found that this led to a 1.5-fold increase in cholesterol accumulation after 48 hr (P < 0.01), compared with controls. At the same time, TRB3 overexpression suppressed inflammation in macrophages as evidenced by reduced expression and secretion of tumor necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1ß) (both P < 0.01). CONCLUSIONS: (1) TRB3 is upregulated in macrophages upon treatment with ox-LDL; (2) TRB3 promotes lipid accumulation and suppresses cytokine expression; and (3) inflammation and foam cell formation can be reciprocally regulated, and TRB3 orients the macrophage to assume a more primary role for lipid accumulation while maintaining a secondary role as an inflammatory immune cell.

RESUMEN

Mature Cystic Teratomas of the ovary are the most common ovarian tumors in both adolescents and reproductive-age women. This case report shows a rare case of squamous cell carcinoma arising from a mature cystic teratoma in a 59-year-old postmenopausal woman. Malignant transformation occurs in 1% of all cases of mature cystic teratomas and due to its rarity, there is no established protocol regarding optimal diagnosis and management. Preoperative diagnosis was difficult due to non-specific symptoms such as abdominal mass and abdominal pain present in this patient. The surgery was planned based on the large size of the tumor on imaging, menopausal age and a family history of breast cancer in the family. She subsequently underwent Total Abdominal Hysterectomy with Bilateral Salpingo-oophorectomy, Frozen Section, Bilateral Lymph Node Dissection, lnfracolic Omentectomy and Right Internal Iliac Artery Ligation. Final diagnosis was confirmed post operatively with the final histopathologic report. This report would show that proper risk assessment and preoperative planning would optimize management of even rare cases of malignant tumors.

RESUMEN

OBJECTIVE: This paper aims to provide concise background information regarding the state of noncommunicable diseases (NCDs) and their risk factors as well as the existing efforts to address them in the Philippines in the last 25 years. METHODS: A desk review of documents and literature review as well as analyses of available statistical data and several consultations with involved government agencies have been made to come up with summary figures and tables.RESULTS: NCDs as well as metabolic conditions that can potentially lead to NCDs are on the rise in the last score of years. The Philippines, through the Department of Health, has been visionary in leading various projects and activities to fight NCDs over the last two decades, and its efforts are slowly paying off: the prevalence of tobacco use and that of hypertension have decreased over the last 5 years. NCD mortality (including premature deaths) and prevalence of behavioral risk factors, however, generally remain high, and the Philippines needs to accelerate whole-of-society and whole-of-government actions to sustain the gains and attain its NCD targets in the next 10 years or so. CONCLUSION: The need to strengthen health system interventions and promote accountability of various sectors in addressing NCDs and its risk factors in the country arises. The development of a multisectoral action plan on NCD prevention and control is needed to halt the rise of NCDs in the country.

RESUMEN

Several theories propose that self-esteem, or positive self-regard, results from fulfilling the value priorities of one's surrounding culture. Yet, surprisingly little evidence exists for this assertion, and theories differ about whether individuals must personally endorse the value priorities involved. We compared the influence of four bases for self-evaluation (controlling one's life, doing one's duty, benefitting others, achieving social status) among 4,852 adolescents across 20 cultural samples, using an implicit, within-person measurement technique to avoid cultural response biases. Cross-sectional and longitudinal analyses showed that participants generally derived feelings of self-esteem from all four bases, but especially from those that were most consistent with the value priorities of others in their cultural context. Multilevel analyses confirmed that the bases of positive self-regard are sustained collectively: They are predictably moderated by culturally normative values but show little systematic variation with personally endorsed values.

RESUMEN

The motive to attain a distinctive identity is sometimes thought to be stronger in, or even specific to, those socialized into individualistic cultures. Using data from 4,751 participants in 21 cultural groups (18 nations and 3 regions), we tested this prediction against our alternative view that culture would moderate the ways in which people achieve feelings of distinctiveness, rather than influence the strength of their motivation to do so. We measured the distinctiveness motive using an indirect technique to avoid cultural response biases. Analyses showed that the distinctiveness motive was not weaker-and, if anything, was stronger-in more collectivistic nations. However, individualism-collectivism was found to moderate the ways in which feelings of distinctiveness were constructed: Distinctiveness was associated more closely with difference and separateness in more individualistic cultures and was associated more closely with social position in more collectivistic cultures. Multilevel analysis confirmed that it is the prevailing beliefs and values in an individual's context, rather than the individual's own beliefs and values, that account for these differences.

RESUMEN

Transarterial chemoembolization (TACE) is one of the standard therapies for bridging patients with hepatocellular carcinoma (HCC) to transplantation. This study was designed to determine which features on pre- and post-TACE imaging are associated with tumor necrosis in pathological specimens. Records of 105 patients with 132 HCC lesions who underwent liver transplantation after TACE were retrospectively reviewed. In 70% of the nodules, >90% necrosis was achieved. The development of >90% lesion necrosis upon pathological analysis was associated with avid lesion enhancement (P = 0.03) and the presence of a feeding vessel larger than 0.9 mm in diameter on the pre-TACE visceral angiogram (P = 0.01). Near-complete lesion necrosis was also associated with an extensive accumulation of ethiodized oil within a lesion during TACE administration (P = 0.04). On post-TACE computed tomography imaging, a lack of residual contrast enhancement (P < 0.0001), a decrease in the lesion size (P = 0.04), a high lesion density due to an accumulation of ethiodized oil (P = 0.03), and a diffuse distribution of ethiodized oil throughout the lesion (P = 0.0001) were also correlated with near-complete lesion necrosis upon pathological analysis. In conclusion, this study found multiple pre- and post-TACE imaging characteristics of HCC that were associated with near-complete tumor necrosis upon histopathological analysis after TACE. These findings may help to guide the selection of an optimal treatment strategy for bridging patients with HCC to liver transplantation.
