PURPOSE: The purpose of this project was to explore the parental experience of making a "do not resuscitate" (DNR) decision for their child who is or was cared for in a pediatric intensive care unit in Taiwan. METHODS: A descriptive qualitative study was conducted following parental signing of a standard hospital DNR form on behalf of their critically ill child. Sixteen Taiwanese parents of 11 children aged 1 month to 18 years were interviewed. Interviews were recorded, transcribed, analyzed and sorted into themes by the sole interviewer plus other researchers. RESULTS: Three major themes were identified: (a) "convincing points to sign", (b) "feelings immediately after signing", and (c) "postsigning relief or regret". Feelings following signing the DNR form were mixed and included "frustration", "guilt", and "conflicting hope". Parents adjusted their attitudes to thoughts such as "I have done my best," and "the child's life is beyond my control." Some parents whose child had died before the time of the interview expressed among other things "regret not having enough time to be with and talk to my child". CONCLUSION: Open family visiting hours plus staff sensitivity and communication skills training are needed. To help parents with this difficult signing process, nurses and other professionals in the pediatric intensive care unit need education on initiating the conversation, guiding the parents in expressing their fears, and providing continuing support to parents and children throughout the child's end of life process.

Purpose: Perinatal distress, especially depression, commonly occurs during pregnancy and the first year postpartum, but this medical condition are often undiagnosed and untreated. The present study explored how women with depressive symptoms during the perinatal period who had participated in a mindfulness course applied the training and perceived its effects. Methods: This descriptive qualitative study included 16 women with probable perinatal depression who had participated in an 8-week mindfulness-based childbirth and parenting program during their pregnancy and agreed to be interviewed. One-to-one in-depth interviews were conducted and recorded following the completion of the mindfulness course, approximately 1 month after childbirth. Verbatim transcripts were analyzed using content analysis. Results: We proposed three themes and six subthemes relating to first-time mothers’ experiences during and after the group mindfulness-based intervention: learning to be aware of the body and mind (confronting awareness of physical change, managing negative feelings differently), building positive family relationships (strengthening the motherebaby bond, developing a satisfactory marital partnership), and overcoming ongoing challenges (conquering childbirth pain with confidence, accepting unexpected situations). Three main themes were generated to demonstrate how women experience the effects of mindfulness training. Conclusions Mindfulness-based interventions helped the participants develop insight into their mood and physical changes and accept their childbirth process. Therefore, mindfulness education programs can be incorporated into prenatal care to enhance the management of the depressive symptoms of perinatal women.

BACKGROUND AND OBJECTIVES: Oxidative stress plays an important role in the pathogenesis of coronary atherosclerosis and spasm. We investigated whether the polymorphisms in two oxidative stress-related genes, paraoxonase and p22phox, are associated with risks of coronary artery spasm and stenosis. SUBJECTS AND METHODS: The study comprised of 116 patients with variant angina, 118 patients with coronary artery stenosis and 117 control subjects, who were all classified by coronary angiography. In all three groups, the genotype frequencies of the Q192R polymorphism of the paraoxonase gene and C242T polymorphism of the p22phox gene were analyzed, and the serum thiobarbituric acid-reactive substance concentrations measured. RESULTS: The frequency of the RR genotype of the paraoxonase Q192R polymorphism was significantly higher in patients with variant angina and coronary artery stenosis than in the control subjects (40.4% in variant angina and 37.8% in coronary artery stenosis vs. 24.7% in control, p=0.020 and 0.048, respectively). From the multivariate analysis, the odds ratio of the RR genotype was 2.240 for variant angina (95% confidence interval ; 1.012-4.956), and 2.333 for coronary artery stenosis (95% confidence interval ; 1.140-4.777), in relation to the control subjects. The thiobarbituric acid-reactive substance level was significantly higher in the RR type than in the QQ+QR types (RR vs. QQ+QR : 1.106+/-0.420 nmol/mL vs. 0.949+/-0.311 nmol/mL, p=0.028). There was no significant difference in the prevalence of the C242T polymorphism of the p22phox gene between the three groups. CONCLUSION: The RR genotype of the paraoxonase gene Q192R polymorphism was found to be an independent risk factor for both coronary spasm and stenosis.

INTRODUCTION: The rising prevalence of multiple chronic diseases is an important public health issue as it is associated with increased healthcare utilisation. This paper aimed to explore the annual per capita healthcare cost in primary care for patients with multiple chronic diseases (multimorbidity). METHODS: This was a retrospective cohort study conducted in a cluster of public primary care clinics in Singapore. De-identified data from electronic medical records were extracted from July 2015 to June 2017. Only patients with at least 1 chronic disease were included in the study. Basic demographic data and healthcare cost were extracted. A list of 20 chronic diseases was considered for multimorbidity. RESULTS: There were 254,377 patients in our study population, of whom 52.8% were female. The prevalence of multimorbidity was 62.4%. The median annual healthcare cost per capita for patients with multimorbidity was about twice the amount compared to those without multimorbidity (SGD683 versus SGD344). The greatest percentage increment in cost was when the number of chronic diseases increased from 2 to 3 (43.0%). CONCLUSION Multimorbidity is associated with higher healthcare cost in primary care. Since evidence for the optimal management of multimorbidity is still elusive, prevention or delay in the onset of multimorbidity in the general population is paramount.

Background: AMP-activated protein kinase (AMPK) is a key enzyme for cellular energy homeostasis and improves metabolic disorders. Brown and beige adipose tissues exert thermogenesis capacities to dissipate energy in the form of heat. Here, we investigated the beneficial effects of the antioxidant alpha-lipoic acid (ALA) in menopausal obesity and the underlying mechanisms. Methods: Female Wistar rats (8 weeks old) were subjected to bilateral ovariectomy (Ovx) and divided into four groups: Sham (n=8), Ovx (n=11), Ovx+ALA2 (n=10), and Ovx+ALA3 (n=6) (ALA 200 and 300 mg/kg/day, respectively; gavage) for 8 weeks. 3T3-L1 cells were used for in vitro study. Results: Rats receiving ALA2 and ALA3 treatment showed significantly lower levels of body weight and white adipose tissue (WAT) mass than those of the Ovx group. ALA improved plasma lipid profiles including triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Hematoxylin & eosin staining of inguinal WAT showed that ALA treatment reduced Ovx-induced adipocyte size and enhanced uncoupling protein 1 (UCP1) expression. Moreover, plasma levels of irisin were markedly increased in ALA-treated Ovx rats. Protein expression of brown fat-specific markers including UCP1, PRDM16, and CIDEA was downregulated by Ovx but markedly increased by ALA. Phosphorylation of AMPK, its downstream acetyl-CoA carboxylase, and its upstream LKB1 were all significantly increased by ALA treatment. In 3T3-L1 cells, administration of ALA (100 and 250 μM) reduced lipid accumulation and enhanced oxygen consumption and UCP1 protein expression, while inhibition of AMPK by dorsomorphin (5 μM) significantly reversed these effects. Conclusion ALA improves estrogen deficiency-induced obesity via browning of WAT through AMPK signaling.

BACKGROUND AND OBJECTIVES: The 5-HT2A receptor is one of the main mediators of a serotonin-evoked coronary artery contraction. This is because vasoconstriction is selectively blocked by the 5-HT2 receptor antagonist, with the 5-HT2A receptor gene mRNA being detected in spastic coronary arteries. The relationship between the T102C polymorphism of the 5-HT2A receptor gene and the response to the 5-HT2A antagonist (clozapine) has recently been established, suggestive of a functional implication. Previous studies have observed an association between low cholesterol levels and mental disorders, but the underlying cause has not been determined. It has been established that the T102C polymorphism of the 5-HT2A serotonin receptor gene and a variety of psychological problems are related, but the relationship between the serum lipid level and this genetic polymorphism has not been reported. We investigated the influence of this polymorphism on coronary artery disease, including vasospastic angina and the clinical parameters, such as the lipid profile. SUBJECTS AND METHODS: After a diagnostic angiography was performed, the genotype was identified from the genomic DNA extracted from the peripheral blood of 646 patients without specific psychiatric diseases. RESULTS: There were no differences in the genotype frequencies between coronary artery disease, coronary artery disease with vasospasm, and the normal control groups, even from a subgroup analysis of the clinical parameters. Contrary to previous reports, the genotype distribution was not related to a myocardial infarction or hypertension. The lipid profile analysis showed significantly lower total cholesterol (193.5 vs. 202.1mg/dL, p=0.016) and HDL-cholesterol (42.7 vs. 46.2mg/dL, p=0.003) levels in the CC genotype than the other genotypes, and the frequencies of CC genotype showed a significantly decreasing trend between the HDL-cholesterol (p=0.003) and total cholesterol (p=0.003) quartiles. From a multivariate analysis, only the HDL-cholesterol level was significantly associated with a lower frequency of the CC genotype (p=0.006). CONCLUSION: The T102C polymorphism is not related to coronary artery disease, including vasospasm of the coronary artery, but the CC genotype of this polymorphism is related to low HDL-cholesterol. We identified a novel genetic polymorphism of the serotonin receptor, which affects the HDL-cholesterol level. Because previous observational studies have shown an association between low cholesterol levels and mental disorders, our data should be considered when analyzing the serum lipid levels and serotonin receptor function in humans.
