RESUMO

BACKGROUND: The exploration of discrimination, social acceptance, and their impact on the psychological well-being of older men who have sex with men (MSM) is a critical area of study within the broader field of LGBTQ+ research. This demographic, comprising individuals who identify as both male and homosexual and are aged in the older spectrum of the population, faces unique challenges that intersect age, sexual orientation, and societal attitudes. Objectives This study aimed to explore the relationship between social acceptance and isolation with discrimination and the impact on the psychological well-being of older MSM. METHODS: A cross-sectional survey was administered among older MSM residing in three distinct regions: the People's Republic of China (PRC), Hong Kong, and Taiwan, with a total sample size of N = 453 participants, evenly distributed with N = 151 individuals from each region. The survey included the General Health Questionnaire-12 (GHQ-12), the Discrimination and Self-Stigma Evaluation Scale (DSSES), and the Perceived Acceptance Scale (PAS) which measures the perceived social acceptance from friends, mother, father, and family. The data were analyzed using descriptive statistics, ANOVA, and regression analysis. RESULTS: The mean scores of the GHQ-12 indicated that the participants had a moderate level of psychological distress, with a mean score of 6.38 (SD = 2.55). The DSSES mean score was 27.78 (SD = 8.73), indicating that participants experienced discrimination in their everyday lives. The PAS mean score was 3.08 (SD = 0.48), indicating that participants had a moderate level of perceived social acceptance. These results suggest that discrimination and social acceptance differ among older MSM in different areas in PRC, Hong Kong, and Taiwan. CONCLUSIONS: The study highlights the impact of discrimination and social acceptance on the psychological well-being of older MSM. The findings suggest that interventions aimed at reducing discrimination and promoting social acceptance may improve the psychological well-being of older MSM. These results have important implications for healthcare providers and policymakers in developing strategies to promote social acceptance and reduce discrimination towards older MSM.

RESUMO

BACKGROUND: Hypertension affects more than 1 billion people worldwide. Hypertension management guidelines recommend regular exercise to control blood pressure. Tai Chi is a low-impact, low- to moderate-intensity exercise that has numerous health benefits. OBJECTIVE: The aim of this study is to perform a review of meta-analyses and summarize the existing information on the health benefits of Tai Chi for patients with hypertension. METHODS: This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Eight health-related databases were systematically searched from their inception to March 2021 to identify the relevant meta-analyses. Two reviewers independently assessed the methodological quality of the evidence. RESULTS: A total of 6 relevant meta-analyses were included in this review: 3 were rated as critically low in quality, 2 were rated low, and 1 was rated high. In the included meta-analyses, Tai Chi showed many benefits for patients with hypertension. In addition to improving blood pressure, the blood lipid profile, blood sugar, body measurements, and quality of life of patients improved significantly after practicing Tai Chi. CONCLUSION: Tai Chi may be considered an effective and safe alternative exercise for patients with hypertension.

RESUMO

Individuals within the Lesbian, Gay, Bisexual, Transgender and Queer (LGBTQ) community who are diagnosed with cancer experience inequitable treatment in healthcare systems worldwide, resulting in dissatisfaction, communication challenges with healthcare providers, and a deep sense of disappointment. Stigma, discrimination, and perceived homophobia further heighten the risk of psychological and attitudinal disorders, including depression and suicidal tendencies, among LGBTQ cancer patients. To comprehensively assess the discrimination faced by LGBTQ cancer patients and gain deeper insights into their needs and experiences, we conducted a systematic review following PRISMA guidelines. We searched for relevant articles using specific keywords in reputable databases such as PubMed, Google Scholar, and PsycINFO. We rigorously evaluated article quality using the CASP (Critical Appraisal Skills Programme) checklist. From a total of 75 eligible studies, we carefully selected 14 studies, specifically examining LGBTQ cancer patients who were currently undergoing or had previously undergone cancer treatment. The studies revealed various factors, including unmet needs related to anxiety and depression, instances of discrimination, disparities in care, and inadequate support systems. A majority of patients expressed dissatisfaction with their cancer care and continued to encounter discrimination and disparities throughout their treatment journeys. Consequently, this led to heightened levels of anxiety, stress, depression, and negative perceptions of healthcare providers. Based on these findings, we recommend providing specialized training to social workers and healthcare providers. This training will equip them with the necessary skills and knowledge to deliver culturally sensitive care tailored to the unique needs of LGBTQ cancer patients. By addressing discrimination, reducing disparities, and fostering an inclusive environment, healthcare professionals can strive to ensure that LGBTQ cancer patients receive the care they deserve.

RESUMO

BACKGROUND: An aging population and required hypertension control are global concerns that burden the healthcare system. Text messaging interventions have been developed to support hypertension management, but their effects on the older population are unknown. OBJECTIVES: This review aimed to identify the effects of a text messaging intervention on hypertension management among older adults. METHODS: Four English and two Chinese databases with randomized controlled trials published between January 2010 and December 2020 were searched. The mean age of the participants was 60 years or above. Participants were also diagnosed with hypertension. The Cochrane risk-of-bias tool was used for the critical appraisal. Data in each study were extracted, and a meta-analysis was presented in terms of mean difference (MD) and standardized mean difference (SMD). RESULTS: A total of 1670 records were screened, of which six were included in the final review. The intervention of the included studies lasted up to 6 months, and one-way text messaging was commonly used. Meta-analysis showed that a text messaging intervention significantly reduced systolic blood pressure (MD = -6.11, p < .01) but not diastolic blood pressure. Regarding medication adherence, a moderate effect was noted with the use of text messaging among older adults with hypertension (SMD = 0.65, p = .01). LINKING EVIDENCE TO ACTION: A text messaging intervention can improve hypertension management among older adults. The standardized content of one-way text messaging is suggested to be delivered weekly.

RESUMO

Cancer cells are high in heterogeneity and versatility, which can easily adapt to the external stresses via both primary and secondary resistance. Targeting of tumour microenvironment (TME) is a new approach and an ideal therapeutic strategy especially for the multidrug resistant cancer. Recently, we invented AANG, a natural compound formula containing traditional Chinese medicine (TCM) derived Smad3 inhibitor Naringenin (NG) and Smad7 activator Asiatic Acid (AA), for rebalancing TGF-ß/Smad signalling in the TME, and its implication on the multidrug resistance is still unexplored. Here, we observed that an equilibrium shift of the Smad signalling in patients with hepatocellular carcinoma (HCC), which was dramatically enhanced in the recurrent cases showing p-glycoprotein overexpression. We optimized the formula ratio and dosage of AANG that effectively inhibit the proliferation of our unique human multidrug resistant subclone R-HepG2. Mechanistically, we found that AANG not only inhibits Smad3 at post-transcriptional level, but also upregulates Smad7 at transcriptional level in a synergistic manner in vitro. More importantly, AANG markedly suppressed the growth and p-glycoprotein expression of R-HepG2 xenografts in vivo. Thus, AANG may represent a novel and safe TCM-derived natural compound formula for overcoming HCC with p-glycoprotein-mediated multidrug resistance.

RESUMO

Transforming growth factor-ß (TGF-ß) signaling triggers diverse biological actions in inflammatory diseases. In tissue fibrosis, it acts as a key pathogenic regulator for promoting immunoregulation via controlling the activation, proliferation, and apoptosis of immunocytes. In cancer, it plays a critical role in tumor microenvironment (TME) for accelerating invasion, metastasis, angiogenesis, and immunosuppression. Increasing evidence suggest a pleiotropic nature of TGF-ß signaling as a critical pathway for generating fibrotic TME, which contains numerous cancer-associated fibroblasts (CAFs), extracellular matrix proteins, and remodeling enzymes. Its pathogenic roles and working mechanisms in tumorigenesis are still largely unclear. Importantly, recent studies successfully demonstrated the clinical implications of fibrotic TME in cancer. This review systematically summarized the latest updates and discoveries of TGF-ß signaling in the fibrotic TME.

RESUMO

BACKGROUND: Discrimination and inequality have been identified as significant problems faced by transgender individuals in sports participation. However, uncertainties remain regarding the effectiveness of interventions aimed at promoting equality. OBJECTIVES: This systematic review and meta-analysis aimed to examine the experiences of transgender athletes in sports, focusing on mental health issues and factors contributing to inequality among transgender and other sexual minorities. METHODS: The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched 10 electronic databases, including PubMed, Google Scholar, and Web of Science, to identify eligible studies published between 2005 and 2022. The search yielded 1430 articles, of which only 12 studies met the inclusion criteria for this review. RESULTS: The meta-analysis of the 12 studies included in this review revealed that transgender athletes faced social discrimination and inequality in sports participation, resulting in mental health problems and higher rates of suicide. From a cohort of 21,565 participants in the studies, 7152 (33%) were subjected to discrimination in sports participation and healthcare, with a rate of 0.61 (95% confidence interval [CI]: 0.35, 0.81). However, transgender athletes who felt welcomed and embraced by their respective teams accounted for 0.39 (95% CI: 0.19, 0.65). These results indicated significant differences between how transgender athletes are treated in healthcare settings and when participating in sports. CONCLUSION: The study findings underscore the need for policies, cultural research, and interventions to address discrimination and inequality faced by transgender athletes in sports participation. Promoting equality and safeguarding the rights of transgender athletes can mitigate the risk of mental health problems and increase physical activity among sexual minorities.

RESUMO

Perceived health and distresses are associated with the practice of lifestyle modifications, which increases the risk of diabetes and hypertension-related complications. This study aimed to define the characteristics and distribution of perceived health and distresses across the states between people with diabetes and hypertension. Data were derived from a national survey of US adults aged ≥18 years who were interviewed via phone call. Perceived health and distresses were assessed through corresponding questions. An amount of 333,316 respondents (43,911 with diabetes and 130,960 with hypertension) were included in the analysis; 61.8% of people with diabetes and 74.5% of people with hypertension reported having good or better health, while residents in the Southwest region perceived poor health statuses and more distresses. Education level (diabetes: odds ratio [OR] = 0.47-0.79, hypertension: OR = 0.42-0.76), employment status level (diabetes: OR = 1.40-2.22, hypertension: OR = 1.56-2.49), and household income (diabetes: OR = 0.22-0.65, hypertension: OR = 0.15-0.78) were significant factors associated with poorly perceived health among people with diabetes and hypertension, and the use of technology and strategies for policymakers are suggested to improve the perceived health status in this regard.

RESUMO

Purpose: This study investigated the prevalence rates of various types of intimate partner violence (IPV) among lesbian, gay, and bisexual (LGB) adults in Hong Kong and examined the associations between IPV and different addictive behavior and mental health problems. Methods: A total of 759 LGB adults completed an online cross-sectional survey between November 2021 and February 2022. Data on past-year IPV and LGB-specific tactics (whether perpetrated or experienced by participants), addictive behavior, anxiety, depression, and demographics were collected and analyzed with descriptive statistics and logistic regressions. Results: Psychological aggression was the most common type of IPV within an LGB relationship (22.1%), followed by physical assault (10.8%) and IPV-related injury (4.1%). LGB-specific tactics were experienced by 39.0% of the LGB adults. Depression, anxiety, and frequent gambling were significantly associated with specific types of IPV and LGB-specific tactics. Conclusion: IPV was prevalent in the LGB population. Findings on correlates provided insights for future development of IPV detection and intervention.

RESUMO

Macrophage-myofibroblast transition (MMT) is a newly discovered pathway for mass production of pro-tumoral cancer-associated fibroblasts (CAFs) in non-small cell lung carcinoma (NSCLC) in a TGF-ß1/Smad3 dependent manner. Better understanding its regulatory signaling in tumor microenvironment (TME) may identify druggable target for the development of precision medicine. Here, by dissecting the transcriptome dynamics of tumor-associated macrophage at single-cell resolution, a crucial role of a hematopoietic transcription factor Runx1 in MMT formation is revealed. Surprisingly, integrative bioinformatic analysis uncovers Runx1 as a key regulator in the downstream of MMT-specific TGF-ß1/Smad3 signaling. Stromal Runx1 level positively correlates with the MMT-derived CAF abundance and mortality in NSCLC patients. Mechanistically, macrophage-specific Runx1 promotes the transcription of genes related to CAF signatures in MMT cells at genomic level. Importantly, macrophage-specific genetic deletion and systemic pharmacological inhibition of TGF-ß1/Smad3/Runx1 signaling effectively prevent MMT-driven CAF and tumor formation in vitro and in vivo, representing a potential therapeutic target for clinical NSCLC.

RESUMO

Immunodynamics in the tumor microenvironment can be precisely examined by using multiple antigen identification approaches. Here, we present a protocol for capturing expression levels of multiple target proteins in the same specimen at single-cell resolution using a tyramide signal amplification-based immunofluorescent multiplexing system. We describe steps for tumor tissue microarray preparation, multiplex immunohistochemistry staining, image acquisition, and quantification. This protocol can quantify immune cells in tissues from patients or experimental disease models at a protein level. For complete details on the use and execution of this protocol, please refer to Chung et al. (2023),1 Tang et al. (2022),2 and Tang et al. (2022).3.

RESUMO

BACKGROUND: Mental health disparities have been documented among lesbian, gay, and bisexual (LGB) adults in the United States. Substance use disorders and suicidal ideation have been identified as important health concerns for this population. However, the interrelationships among these factors are not well understood. OBJECTIVE: This study aims to investigate the interrelationships among mental health, substance use disorders, and suicidal ideation among LGB adults in the United States using a population-based statewide survey. METHODS: Our study was an observational cross-sectional analysis, and the data for this study were collected from a sample of LGB adults who participated in the statewide survey. The survey collected information on mental health, substance use disorders, and suicidal ideation using validated measures. Descriptive statistics and inferential data analysis were conducted to explore the interrelationships among these factors. RESULTS: The results showed that LGB adults who reported higher levels of depression and drug abuse and dependence also reported higher levels of suicidal tendency and mental illness. Inferential data analysis using χ2 tests revealed significant differences in depression score (χ22=458.241; P<.001), drug abuse and dependence score (χ22=226.946; P<.001), suicidal tendency score (χ22=67.795; P<.001), and mental illness score (χ22=363.722; P<.001) among the 3 sexual identity groups. Inferential data analysis showed significant associations between sexual identity and mental health outcomes, with bisexual individuals reporting the highest levels of depression, drug abuse and dependence, suicidal tendency, and mental illness. CONCLUSIONS: This study provides important insights into the interrelationships among mental health, substance use disorders, and suicidal ideation among LGB adults in the United States. The findings underscore the need for targeted interventions and research aimed at addressing the mental health needs of sexual minority populations. Future research should aim to better understand the underlying mechanisms driving these disparities and develop culturally sensitive and tailored interventions that meet the unique needs of LGB individuals. Reducing stigma and discrimination against sexual minority populations is also crucial to improving their mental health outcomes.

RESUMO

BACKGROUND: Practicing healthy lifestyles can reduce the risk to develop noncommunicable diseases and the related mortality. Studies showed that practicing healthy lifestyles could enhance disease-free life expectancy and preserve bodily functions. However, engagement in healthy lifestyle behavior was suboptimal. OBJECTIVE: This study aimed to define individuals' lifestyle characteristics before and during COVID-19 and determine the factors associated with practicing a healthy lifestyle. This cross-sectional study was conducted using data from the 2019 and 2021 Behavioral Risk Factor Surveillance System surveys. METHODS: US individuals aged ≥18 years were interviewed via phone call. Healthy lifestyles were assessed through corresponding questions regarding the maintenance of optimal body weight, physical activity, daily consumption of at least five portions of fruits and vegetables, current smoking status, and alcohol consumption. Missing data were imputed using a package in the R statistical software. The effects of practicing a healthy lifestyle on cases without missing data and those with imputation were reported. RESULTS: There were 550,607 respondents (272,543 and 278,064 from 2019 and 2021, respectively) included in this analysis. The rates of practicing a healthy lifestyle were 4% (10,955/272,543) and 3.6% (10,139/278,064) in 2019 and 2021, respectively. Although 36.6% (160,629/438,693) of all 2021 respondents had missing data, the results of the logistic regression analysis for cases without missing data and those with imputation were similar. Of the cases with imputation, women (odds ratio [OR] 1.87) residing in urban areas (OR 1.24) with high education levels (OR 1.73) and good or better health status (OR 1.59) were more likely to practice healthier lifestyles than young individuals (OR 0.51-0.67) with a low household income (OR 0.74-0.78) and chronic health conditions (OR 0.48-0.74). CONCLUSIONS: A healthy lifestyle should be strongly promoted at the community level. In particular, factors associated with a low rate of practice of healthy lifestyles should be targeted.

RESUMO

Transforming growth factor-ß (TGF-ß) signaling is an important pathway for promoting the pathogenesis of inflammatory diseases, including cancer. The roles of TGF-ß signaling are heterogeneous and versatile in cancer development and progression, both anticancer and protumoral actions are reported. Interestingly, increasing evidence suggests that TGF-ß enhances disease progression and drug resistance via immune-modulatory actions in the tumor microenvironment (TME) of solid tumors. A better understanding of its regulatory mechanisms in the TME at the molecular level can facilitate the development of precision medicine to block the protumoral actions of TGF-ß in the TME. Here, the latest information about the regulatory mechanisms and translational research of TGF-ß signaling in the TME for therapeutic development had been summarized.

RESUMO

This study aimed to investigate the prevalence of lower urinary tract symptoms (LUTS) in older men (N= 3056) with benign prostatic hyperplasia (BPH) and its effects on their sexual function and mental health. Descriptive, correlation, and regression analyses were used to explore the relationships between prostate and lower urinary tract health and psychological well-being. Better prostate and lower urinary tract health positively affected psychological well-being, and sexual function also had a positive influence. LUTS have an adverse impact on sexual function and mental health. Early intervention is crucial for mitigating the negative impact of LUTS on the quality of life in older men. Addressing prostate and lower urinary tract health issues through appropriate interventions may improve psychological well-being. Health care professionals must consider the adverse effects of BPH and LUTS on sexual function and mental health, and implement interventions to enhance the overall quality of life in older men.

RESUMO

Tumour-Associated Macrophages (TAMs) are one of the pivotal components of the tumour microenvironment. Their roles in the cancer immunity are complicated, both pro-tumour and anti-cancer activities are reported, including not only angiogenesis, extracellular matrix remodeling, immunosuppression, drug resistance but also phagocytosis and tumour regression. Interestingly, TAMs are highly dynamic and versatile in solid tumours. They show anti-cancer or pro-tumour activities, and interplay between the tumour microenvironment and cancer stem cells and under specific conditions. In addition to the classic M1/M2 phenotypes, a number of novel dedifferentiation phenomena of TAMs are discovered due to the advanced single-cell technology, e.g., macrophage-myofibroblast transition (MMT) and macrophage-neuron transition (MNT). More importantly, emerging information demonstrated the potential of TAMs on cancer immunotherapy, suggesting by the therapeutic efficiency of the checkpoint inhibitors and chimeric antigen receptor engineered cells based on macrophages. Here, we summarized the latest discoveries of TAMs from basic and translational research and discussed their clinical relevance and therapeutic potential for solid cancers.

RESUMO

We were intrigued by Hanum et al, who published a study on the prevalence of human immunodeficiency virus (HIV) in homosexual, bisexual, and other men who have sex with men at sexual health clinics in England and the relationship between baseline variables and future HIV occurrence. Chemically-enhanced sexual experience (chemsex) is becoming a global phenomenon. There are increasing medical and academic concerns about chemsex, where substances are used to boost sexual satisfaction, which is prevalent in groups, especially among homosexuals. Lesbians, gays, bisexuals, transgenders, and queers have become increasingly visible, valued, and committed community. However, chemsex requires urgent attention.

RESUMO

Older adults' mental health and suicidal tendencies have garnered much attention because of their vulnerability. Few studies have examined the impact of psychological well-being and suicide attempts among older men who have sex with men (OMSM). This study examines the levels of depression and suicidal tendencies among OMSM, factors impacting their mental health, and their likelihood of committing suicide. Descriptive statistics are used to analyze the correlation between depression and suicidal tendencies among OMSM in the United States. We constructed a regression model using relevant data, and scales were selected based on a literature review. The validity and relevance of the control variables were considered. Depression and suicidal tendencies were dependent variables. Data were obtained from the U.S. General Social Survey and analyzed with an ordinary least squares model. There were significant differences between MSM and general groups in depression and suicidal tendency scores (t = 67.084, 58.193, p < .01). Compared with general groups, MSM scored significantly higher on depression and suicidal tendencies. The regression analysis revealed that sex with men was associated with depression and suicidal tendencies (p < .01) among older men. This indicates that OMSM generally have higher levels of depression and suicidal tendencies than the general population. Finally, in the intermediary test, the level of depression had a significant mediating effect on the relationship between homosexuality and suicidal tendencies (p < .01). This suggests that depression intervention can help reduce suicidal tendencies among OMSM.

RESUMO

For scholars, practitioners, and legislators concerned about sexual minority adolescents, one of the main goals is to create more positive and inclusive learning environments for this minority group. Numerous factors, such as repeated patterns of homophobic bullying by classmates and others in school, have been a significant barrier to achieving this goal. In addition, lesbian, gay, bisexual, transgender, and queer (LGBTQ) adolescents encounter substantial inequality across a broad spectrum of wellbeing and education consequences. Compared with their heterosexual counterparts, LGBTQ adolescents experience more anxiety, depression, suicidal thoughts, antisocial behavior, poorer academic performance, less school attachment and protection, and a weaker desire to finish their studies. Such discrepancies based on gender and sexuality were linked to more maltreatment encountered by LGBTQ adolescents. It is crucial to recognize the backgrounds and expectations of LGBTQ adolescents to offer them the best resources. To overcome the inequality and obstacles faced by these LGBTQ adolescents, it is essential to examine tools and techniques that can be utilized. This study examined the literature that explains why society fails to provide enough support to LGBTQ students. Specifically, mechanisms explaining how LGBTQ adolescents interact with others in the learning environment and how such discrepancies arise will be examined. Following that, violence and prejudice, which are fundamental causes of psychological problems among LGBTQ adolescents, will be explored. This review paper thus provides supportive strategies for schools to develop more inclusive learning environments for LGBTQ adolescents.
