RESUMEN

Although overparenting is a growing phenomenon across the globe, there is a severe lack of longitudinal studies examining the trajectory of overparenting and its effects on early adolescent development, particularly in non-Western contexts. The study collected three waves of longitudinal data from 1328 early Chinese adolescents in Hong Kong with an interval of 1 year to examine the stability and change of perceived paternal and maternal overparenting and their effects on adolescent psychological wellbeing. The results indicated that perceived paternal and maternal overparenting declined over time. Besides, adolescents reported lower anxiety and depressive symptoms when they perceived a steep decline in maternal overparenting. Adolescent anxiety at earlier time points also predicted a steeper decline in paternal and maternal overparenting trajectories respectively. Furthermore, we identified gender differences in the initial level of paternal overparenting and the trajectory of maternal overparenting, as well as the effects of rates of change of maternal overparenting on adolescent anxiety and depressive symptoms. The findings give support for self-determination theory and the separation-individuation model, suggesting that changes of overparenting may hinder adolescents' desires for autonomy and self-direction, which may increase their psychological morbidity. The study contributes to theoretical development of contemporary Chinese socialization models and provides useful pointers for future studies of overparenting.

RESUMEN

Introduction: Adolescent children raised in single-mother households, particularly those living in poverty, often need to assume more instrumental and emotional familial responsibilities to cope with family challenges. Method: This study examined the relationships between these filial responsibilities and adolescent psychological wellbeing, as well as the moderating effect of maternal warmth on these relationships via survey. The sample comprised 325 Chinese adolescent children (43.3% girls; Mage = 13.5) from economically disadvantaged single-mother families in Hong Kong. Results: The results indicated that adolescents' instrumental filial responsibilities were positively associated with their life satisfaction. Emotional filial responsibilities, on the other hand, were positively linked to life satisfaction and negatively associated with depression. Furthermore, maternal warmth was found to moderate the relationship between emotional filial responsibilities and life satisfaction. Adolescents who perceived higher levels of maternal warmth and performed more emotional filial responsibilities reported greater life satisfaction than those who performed fewer such responsibilities. Furthermore, the moderating effect of maternal warmth on the relationship between instrumental filial responsibilities and life satisfaction varied between boys and girls. Additionally, the age of the adolescent moderated the effect of maternal warmth on the relationship between emotional filial responsibilities and adolescent anxiety. Discussion: These findings suggest that filial responsibilities do not necessarily impede adolescent wellbeing. Instead, maternal warmth appears to be a crucial family factor that influences the nature of the relationship between filial responsibilities and adolescent wellbeing. These insights are valuable for family scholars and practitioners, informing the design of supportive services to enhance the psychological wellbeing of Chinese adolescents from economically disadvantaged single-mother families.

RESUMEN

BACKGROUND: Normocalcemic hyperparathyroidism can occur, but surgery should not be considered until common etiologies for secondary hyperparathyroidism are comprehensively excluded. Calcium deficiency is an underrecognized cause of normocalcemic parathyroid hormone elevation, and we aim to determine if the implementation of a preoperative calcium challenge can be used to reduce unnecessary parathyroidectomy. METHODS: Consecutive patients referred for parathyroidectomy (1/21-6/22) with normocalcemia (serum calcium <10 mg/dL) and concurrently elevated parathyroid hormone levels were routinely treated with supplemental calcium and vitamin D3, and follow-up laboratory studies were assessed. RESULTS: A total of 29/314 (9%) patients had normocalcemic parathyroid hormone elevation with mean calcium, parathyroid hormone, and vitamin D 25OH levels of 9.5 ± 0.3 mg/dL, 109.9 ± 34.9 pg/mL, and 42.7 ± 23.8 ng/mL respectively. Confounding factors included estimated glomerular filtration rate <60 in 2, loop diuretic use in 4, and prior gastric bypass or gastric sleeve surgery in 4. Follow-up biochemical evaluation was available in 27 (92%); results were unchanged in 7 patients (26%); normalization of parathyroid hormone levels with persistently normal calcium levels occurred in 15 (55%), thus confirming secondary hyperparathyroidism and hypercalcemia with elevated parathyroid hormone levels (classic primary hyperparathyroidism) was diagnosed in 5 (19%). Parathyroid exploration has been completed for 3 of 5 patients with classic primary hyperparathyroidism to date. CONCLUSION: A preoperative calcium challenge was prospectively initiated in normocalcemic patients with parathyroid hormone elevation, and there was high compliance (92%). Short-interval calcium supplementation revealed ∼50% to have resolved secondary hyperparathyroidism due to insufficient calcium intake, which avoided unnecessary surgery. In contrast, classic patients were unveiled in 20%, allowing for prompt and correct surgical intervention.

RESUMEN

Single motherhood and poverty have a significant, negative impact on mothers and their children. When their mothers experience maternal distress, adolescent children have to take up more instrumental and emotional filial responsibilities to comfort their mother and adapt to related changes. Based on 325 mother-child dyads of Chinese single-mother families experiencing economic disadvantage, this study examined the relationship between maternal distress and adolescent mental health problems (indexed by anxiety and depression) and the moderating roles of instrumental and emotional filial responsibilities. Results indicated that maternal distress was positively associated with anxiety and depression in adolescent children. In addition, instrumental filial responsibility intensified the associations of maternal distress with adolescent anxiety and depression. Moreover, the moderating role of emotional filial responsibility in the predictive relationship between maternal distress and adolescent anxiety was different in boys and girls. Adolescent girls with more emotional filial responsibility reported higher adolescent anxiety than did those who shouldered less emotional filial responsibility when their mother exhibited more distress, whereas the relationship between maternal distress and adolescent anxiety was stable in boys, regardless of emotional filial responsibility. In short, the present study showed that parentification was likely to occur in poor Chinese single-mother families, and adolescent children who took up a more caregiving role in the family exhibited poorer mental health. Family counselling and tangible support for single-mother families experiencing economic disadvantage are urged.

RESUMEN

COVID-19 has generated many negative impacts on the family, including impaired psychological well-being of family members (parents and children) and family processes (such as parenting and family functioning). Regarding social policies to support families under the pandemic, there are several missing links. First, COVID-19 related policies mainly focus on physical well-being with a relatively weaker emphasis on psychological well-being. Second, with social policies primarily aiming at stabilizing the "financial capital" of the public, human capital (particularly personal resilience) and social capital (particularly family resilience) are relatively neglected. Third, while "general" social policies may help "averaged" individuals and families, there is a need to take pre-existing family vulnerabilities (such as poverty and caregiving burdens) and inequalities into account when formulating "down to earth" social policies. Fourth, while social science knowledge and theories have important potential contributions to help develop relevant policies and services to promote quality of life under COVID-19, explicit utilization is not strong. With reference to these missing links, we proposed several research and practice directions for the promotion of quality of life under the pandemic.

RESUMEN

The present study aims to examine whether multiple dietary factors affect the mental health of older adults amid the COVID-19 pandemic. It proposes an integrative dietary framework that highlights environmental, nutritional, and social aspects of diet for healthy aging. Based on a sample of 7858 Chinese older adults, the associations between diet and depressive symptoms, along with the rural-urban divide, were examined using zero-inflated negative binomial regression. Overall, protein intake (incidence-rate ratio [IRR] = 0.89, p < 0.001), frequency of family dining together (IRR = 0.98, p < 0.001), and using tap water for cooking (IRR = 0.92, p < 0.01) were associated with lower incidence rates of depressive symptoms among older adults. Among rural older adults, frequency of family dining together (IRR = 0.97, p < 0.001) and tap water use (IRR = 0.89, p < 0.001) were associated with fewer depressive symptoms. However, urban residents who had a higher frequency of family dining together (IRR = 0.98, p < 0.05) and protein intake (IRR = 0.81, p < 0.001) exhibited fewer depressive symptoms. The findings revealed multifaceted dietary pathways towards healthy aging, which call for policies and interventions that improve diet quality for community-dwelling older adults.

RESUMEN

Family resilience is an important protective factor mitigating the negative impact of adversities on individuals and families. As there are very few validated measures of family resilience in the Chinese context, we have developed the Chinese Family Resilience Scale (C-FRS) based on the family resilience framework of Froma Walsh. In this paper, we outline the development and the validation of the C-FRS with reference to the socio-cultural context of Hong Kong. Based on content validation involving family experts, the initial 51 items were assessed in terms of their relevance, clarity, and representativeness. The results showed that these items possessed adequate content validity. In order to validate the 51-item measure, we examined its convergent validity, its factorial validity, and its internal consistency based on the responses of 1020 Chinese families (N = 2858 participants). After removing the items with unsatisfactory psychometric properties, we retained 35 items in the final scale. The results showed that the C-FRS scores were significantly related to family functioning, thus providing support for its convergent validity. This study also provided support for the conceptual model of Walsh (i.e., three high-order domains involving nine primary indicators). Most importantly, the measurement invariance tests showed that the dimensions of the C-FRS were invariant among fathers, mothers, and adolescent children. As the findings support the reliability and the validity of the 35-item C-FRS, we suggest that this measure can be objectively used to assess family resilience in Chinese communities.

RESUMEN

The rise of intense competition for younger generation has intensified social expectations of being a good parent. Based on the data of 386 Chinese intact families with fathers (Mage  = 48.7), mothers (Mage  = 44.7), and adolescents (46.9% girls, Mage  = 14.6) as target respondents, this study examined the patterns of dyadic interdependence in the relationships between socially prescribed parenting perfectionism and parental control (indexed by close monitoring and psychological control) using actor-partner interdependence model (APIM) analyses. Results indicated an actor-only pattern in the association of socially prescribed parenting perfectionism with paternal monitoring, and a couple pattern in the relationship between socially prescribed parenting perfectionism and maternal monitoring. However, the patterns of individual and inter-spousal relationships between socially prescribed parenting perfectionism and psychological control were indistinguishable between fathers and mothers. The findings lend support to the social expectations model and the anxious rearing model by illustrating positive associations of socially prescribed parenting perfectionism with parental monitoring and psychological control. The present study suggests that father-prescribed social expectations about parenting are critical in shaping parental control practice in Chinese contexts, which shed light on the development of Chinese socialization model and clinical practice to support Chinese parents in their parenting.

RESUMEN

Clear cell renal cell carcinoma (ccRCC) is considered an immunotherapy-responsive disease; however, the reasons for this remain unclear. Studies have variably implicated PBRM1 mutations as a predictive biomarker of immune checkpoint blockade (ICB) response, and separate studies demonstrate that expression of human endogenous retroviruses (hERV) might be an important class of tumor-associated antigens. We sought to understand whether specific mutations were associated with hERV expression. Two large, annotated genomic datasets, TCGA KIRC and IMmotion150, were used to correlate mutations and hERV expression. PBRM1 mutations were consistently associated with increased hERV expression in primary tumors. In vitro silencing of PBRM1, HIF1A, and HIF2A followed by RNA sequencing was performed in UMRC2 cells, confirming that PBRM1 regulates hERVs in a HIF1α- and HIF2α-dependent manner and that hERVs of the HERVERI superfamily are enriched in PBRM1-regulated hERVs. Our results uncover a role for PBRM1 in the negative regulation of hERVs in ccRCC. Moreover, the HIF-dependent nature of hERV expression explains the previously reported ccRCC-specific clinical associations of PBRM1-mutant ccRCC with both a good prognosis as well as improved clinical outcomes to ICB.

RESUMEN

Glucocorticoid use is the most common cause of secondary osteoporosis. Poor skeletal health related to glucocorticoid use is thought to involve inhibition of the Wnt/ß-catenin signaling pathway, a key pathway in osteoblastogenesis. Sclerostin, a peptide produced primarily by osteocytes, is an antagonist of the Wnt/ß-catenin signaling pathway, raising the possibility that sclerostin is involved in glucocorticoids' adverse effects on bone. The aim of this study was to determine whether an acute infusion of cosyntropin (i.e. ACTH(1-24)), which increases endogenous cortisol, increases serum sclerostin levels as compared to a placebo infusion. This study was performed using blood samples obtained from a previously published, double-blind, placebo-controlled, randomized, cross-over study among healthy men and women who received infusions of placebo or cosyntropin after being supine and fasted overnight (ClinicalTrials.gov NCT02339506). A total of 17 participants were analyzed. There was a strong correlation (R2 = 0.65, P < 0.0001) between the two baseline sclerostin measurements measured at the start of each visit, and men had a significantly higher average baseline sclerostin compared to women. As anticipated, cosyntropin significantly increased serum cortisol levels, whereas cortisol levels fell during placebo infusion, consistent with the diurnal variation in cortisol. There was no significant effect of cosyntropin as compared to placebo infusions on serum sclerostin over 6-24 h (P = 0.10). In conclusion, this randomized, placebo-controlled study was unable to detect a significant effect of a cosyntropin infusion on serum sclerostin levels in healthy men and women.

RESUMEN

BACKGROUND: Overparenting is an emerging parenting style in which parents over-protect their children from difficulties and challenges by intruding into their lives and providing extensive assistance to them. Unfortunately, longitudinal studies related to overparenting were severely lacking, particularly on its impacts on early adolescents. Moreover, studies examining the mediational pathways through which overparenting is associated with adolescent anxiety are scant. This study examined the mediating role of parent-child conflict (father-child and mother-child) in the relationship between overparenting (paternal and maternal) and adolescent anxiety over time. METHOD: Based on a three-wave longitudinal data of 1074 Chinese early adolescents in Hong Kong, the relationships among paternal and maternal overparenting, father- and mother-child conflict, and adolescent anxiety were assessed. RESULTS: Mother-child conflict mediated the relationship between maternal overparenting and adolescent anxiety over time. Besides, a reverse association of prior adolescent anxiety with subsequent maternal overparenting via mother-child conflict was also identified. In addition, adolescent gender and family intactness did not moderate the relationships among overparenting, parent-child conflict, and adolescent anxiety. DISCUSSION: This present study identified that the bidirectional relationship between maternal overparenting and adolescent anxiety via mother-child conflict over time, which sheds new light on the study of overparenting on adolescent well-being in the Chinese communities.

RESUMEN

Peptide receptor radionuclide therapy (PRRT) is used to treat patients with advanced malignant pheochromocytomas (PCCs) and paragangliomas (PGLs). Patients are at risk of a PRRT-induced catecholamine crisis, and standard guidelines regarding the prevention and management of infusion reactions are lacking. In this case series, the institutional experience of five sequential patients with metastatic PCCs and PGLs receiving PRRT on an outpatient basis is described, of which four had symptomatic tumors and three had a high burden of disease. All patients with symptomatic tumors were treated with preventive management prior to the initiation of PRRT, and no infusion reactions or catecholamine crises were documented. PRRT may be delivered safely on an outpatient basis for patients with metastatic PCCs and PGLs with the involvement of an interdisciplinary team.

RESUMEN

BACKGROUND Cardiac tamponade is a life-threatening pericardial compressive disorder that is a common downstream manifestation of infections, malignancy, and metabolic disorders. Hypothyroidism is a rare cause of tamponade that is attributed to the slow accumulation of effusive fluid into the intrapericardial space. In individuals living with HIV/AIDS, tamponade is commonly associated with infection or malignancy. To our knowledge, this is the first reported case of a patient with HIV/AIDS to have been identified with tamponade secondary to hypothyroidism. CASE REPORT Herein, we describe the case of a 52-year-old male patient with a history of AIDS, who presented with nausea, vomiting, diarrhea, and episodic gastrointestinal discomfort for the past several weeks, in conjunction with progressive fatigue. At initial presentation, he had no hemodynamic or clinical signs of tamponade, but pericardial effusion was incidentally found on imaging. Further investigations revealed an undiagnosed Hashimoto's thyroiditis as a function of restored immunocompetency, which ultimately led to the impending tamponade in this patient. We describe his clinical course through diagnosis of autoimmune hypothyroidism, review cardiac tamponade and hypothyroidism in the context of people living with HIV/AIDS, and discuss this rare manifestation of restored immunocompetency. CONCLUSIONS Hypothyroidism should be ruled out in all patients presenting with pericardial effusions or cardiac tamponade, even in people living with HIV/AIDS or those with a history of immune deficiencies.

RESUMEN

BACKGROUND: Silver nitrate cauterisation is the conventional treatment for peritoneal dialysis catheter exit-site granulomas. However, it requires to be performed by nurses, patients often experience pain and chemical burns. Therefore, the appropriateness and applicability of using 2% aqueous chlorhexidine swabstick as an alternative was explored in two nephrology centres in Hong Kong. OBJECTIVE: To examine possibility of conducting full trial using chlorhexidine swabstick compared with silver nitrate. DESIGN: A pilot study. PARTICIPANTS: Fort-four patients with exit-site granulomas were equally, randomly allocated to receive chlorhexidine swabstick or silver nitrate. MEASUREMENTS: Both groups were followed for 6 weeks to evaluate the time of granuloma subsidence and adverse effects. Pain and treatment satisfaction were assessed using numerical rating scale and self-developed questionnaire, respectively. RESULTS: Healing rates were 94.4% (17 of 18) using chlorhexidine swabstick,100% (21 of 21) using silver nitrate (p = 0.46). The mean time of granuloma subsidence was significantly longer when using chlorhexidine swabstick (32.8 days) than silver nitrate (12.3 days, p=0.02). The chlorhexidine swabstick group reported significantly fewer adverse effects (11.1%, 2 of 18, p = 0.01) compared with the silver nitrate group (52.4%, 11 of 21). The chlorhexidine swabstick group had lower mean pain score (0.5 of 11) than the silver nitrate group (2.4 of 11, p < 0.01). The satisfaction scores between the two groups had no substantial difference. CONCLUSION: Chlorhexidine swabstick took long time to remove granulomas but had similar success rate, less pain, fewer adverse effects than silver nitrate. Additional research is warranted to examine the applicability of chlorhexidine swabstick.

RESUMEN

BACKGROUND: Concerted cultivation is a parenting strategy that parents nurture their children intensively by involving heavily in their children's academic sphere as well as offering them different structured "enrichment" activities so that their children can succeed in the future competitive "rug rat race". While this parenting strategy has been regarded as an effective strategy to promote child and adolescent development, it is deemed to create stress and anxiety for their children. The present study examined the relationship between concerted cultivation and adolescent psychopathology (indexed by depression and anxiety) via parent-child conflict among Chinese adolescents in Hong Kong over time. METHOD: A sample of 1570 young adolescents (48.5% girls, mean age at time 1 = 12.6, SD = 0.76) were recruited from 19 secondary schools in Hong Kong. Adolescents were invited to fill out a questionnaire that contained measures of concerted cultivation, parent-child conflict, anxiety and depression in two consecutive years. RESULTS: Results from structural equation modeling showed that higher levels of paternal concerted cultivation were associated with higher levels of adolescent psychopathology via increased father-child conflict over time. However, maternal concerted cultivation was linked to greater mother-child conflict but reduced father-child conflict, which was associated with adolescent psychopathology. DISCUSSION: Rather than regarding concerted cultivation as an effective parenting strategy that promotes adolescent development, the findings indicated that concerted cultivation increased adolescent psychopathology via increased parent-child conflict. The study sheds new light for family practitioners and educators in their awareness of the adverse effects of concerted cultivation and designing appropriate parent education programs for parents.

RESUMEN

CONTEXT: Hypoglycemia attenuates cardiovascular homeostatic autonomic control. This attenuation, known as the cardiovascular component of hypoglycemia-associated autonomic failure (HAAF), is characterized most notably by decreased baroreflex sensitivity (BRS) that begins during hypoglycemia and persists until at least the next day, despite return to euglycemia. Understanding the mechanisms underlying this reduction in BRS is important because BRS attenuation is associated with increased morbidity and mortality. OBJECTIVE: The objective of this work is to investigate the role of the adrenocorticotropin (ACTH)-adrenal axis in decreasing BRS. We tested the hypothesis that infusion of ACTH 1-24 (cosyntropin), as compared to placebo, would acutely suppress BRS, and that this decrease in BRS would be present the next day. DESIGN: A double-blind, placebo-controlled, random-order, cross-over study was conducted. SETTING: This study took place in a clinical research center. PARTICIPANTS: Participants included healthy men and women. INTERVENTIONS: Interventions included an intravenous infusion of cosyntropin (70 µg/hour for 2.5 hours in the morning and again in the early afternoon) vs normal saline placebo. MAIN OUTCOME MEASURES: Outcome measures included BRS during and 16 hours after cosyntropin vs placebo infusions. RESULTS: Cosyntropin infusion attenuated BRS (mm Hg/ms) as compared to placebo (baseline 17.8 ±â€…1.38 vs 17.0 ±â€…2.07; during 14.4 ±â€…1.43 vs 17.3 ±â€…1.65; and next day 14.8 ±â€…1.42 vs 18.9 ±â€…2.04; P < .05, time by treatment, analysis of variance). BRS was decreased during the final 30 minutes of the morning cosyntropin infusion as compared to baseline (P < .01) and remained suppressed the next day (16 hours after afternoon infusion) (P < .025). Placebo infusion did not significantly change BRS. Corrected QT interval was not affected. CONCLUSIONS: ACTH attenuates BRS, raising the possibility that hypoglycemia-induced increases in ACTH may contribute to the cardiovascular component of HAAF.

RESUMEN

INTRODUCTION: There is a dearth of research on examining the longitudinal effects of cultural family processes on adolescent hopelessness, and the mechanisms through which the effects happen. Hence, the present study examined the relationship among parental (paternal and maternal) sacrifices, filial piety and adolescent hopelessness in the Chinese context. METHODS: The study was based on a three-wave longitudinal data from a sample of 1569 Chinese adolescents (Time 1: mean age = 13.15 ± .92 years; 50.8% girls). The adolescents were invited to fill out a questionnaire containing measurements of studied variables thrice, at an interval of one year. RESULTS: The results of cross-lagged panel analysis indicated that maternal sacrifice was associated with filial piety, which in turn was linked with hopelessness among Chinese adolescents. Moreover, there was bidirectional effects of adolescent hopelessness at earlier time point on paternal and maternal sacrifice at later time point via filial piety. CONCLUSIONS: The study showed that maternal sacrifice serves as a protective factor that reduces adolescents' sense of hopelessness via the development of filial piety. At the same time, the bidirectional indirect effects of filial piety on the relationship between parental sacrifice and adolescent hopelessness also alert family researchers and youth practitioners on the child effects on parental behavior in Chinese families. Theoretical and practical implications of the findings are discussed.

RESUMEN

This study evaluated the effectiveness of a culturally attuned group cognitive-behavior therapy (CBT) intervention for Chinese adolescents at risk for anxiety disorders in Hong Kong and the additive effects of parental involvement. A randomized controlled design was adopted. Assessments were gathered at pre- and posttreatment, and 6-month follow-up. Participants (N = 136) were randomly assigned to (a) CBT plus parental involvement (CBT-PI) (n = 46), (b) CBT (n = 45), and (c) social activity (n = 45) conditions. Data were analyzed according to the intention-to-treat principle using multilevel modeling. The CBT-PI condition showed a greater reduction in physical injury fears compared with the CBT condition. The current findings suggest that involving parents in CBT for Chinese adolescents with anxiety problems may provide a small improvement in treatment efficacy.
