RESUMEN

OBJECTIVE: To develop and validate a population pharmacokinetic (PPK) model of oral olanzapine in pediatric Chinese patients in order to individualize therapy in this population. METHODS: A total of 897 serum concentrations from 269 pediatric patients taking oral olanzapine (ages 8-17 years) were collected. Demographic parameters, biological characteristics and concomitant medications were investigated as covariates. The data were analyzed using a nonlinear mixed-effects modeling approach. Bootstrapping (1000 runs), normalized prediction distribution error (NPDE), and external validation of 62 patients were employed. Simulations were performed to explore the individualized dosing regimens in various situations. RESULTS: The one-compartment model with first-order absorption and elimination had an apparent clearance (CL/F) of 10.38 L/h, a distribution volume (V/F) of 9.41 L/kg and an absorption rate constant (Ka) fixed at 0.3 h-1. The equation was CL∕F (L∕h) = 10.38 × (body weight∕60)0.25 ×1.33 (if male) × 0.71 (if co-occurrence of infection) × 0.51 (if co-therapy with fluvoxamine) × 1.27 (if co-therapy with sertraline) × 1.43 (if co-therapy with valproate). The final model had satisfactory stability, robustness, and predictive ability. The results from a simulation suggested the oral olanzapine doses required for male and female pediatric patients weighing between 40 and 60 kg without co-medication were 10-15 mg/day and 7.5-10 mg/day, respectively, and dosage adjustments should be based on sex and body weight; and co-administrated with valproate, sertraline, or fluvoxamine. CONCLUSION: This model may help individualize optimum dosing of oral olanzapine for pediatric patients.

RESUMEN

Subjective cognitive complaints (SCCs) are a crucial modifiable risk factor for dementia. There is increasing interest in the association between SCC and sleep disturbance; however, the effects of sleep disturbance on SCC development among community-dwelling elderly individuals in Japan remain unclear. We aimed to cross-sectionally investigate the association between SCC and sleep disturbance, with adjustment for multiple factors related to cognitive decline, among 241 community-dwelling elderly persons without cognitive impairment. The measures were SCCs (Kihon Checklist-Cognitive Function, KCL-CF), sleep disturbance (Japanese version of the Athens Insomnia Scale, AIS-J), general cognitive function (Mini-Mental State Examination), and depressive symptoms (five-item version of the Geriatric Depression Scale [GDS-5]). The following data were collected: sex, age, educational history, whether the participants had visited a medical institution for diseases (hypertension, diabetes, hyperlipidemia, heart disease), and the presence/absence of established risk factors (hearing loss, history of head injury, drinking habits, smoking habits, social isolation, and physical inactivity and activity). Based on the KCL-CF, 96 and 145 participants were considered to have and lack SCCs, respectively. On logistic regression analysis, the AIS-J score and smoking history were significantly associated with SCCs. Our findings suggest that sleep disturbance is associated with SCC development among community-dwelling elderly people in Japan. Evaluating and managing sleep disturbances can be important in preventing SCCs and dementia.

RESUMEN

OBJECTIVE: To investigate the postoperative effect of double-lid blepharoplasty based on the histological difference in the upper eyelid of Asian patients. MATERIAL AND METHODS: A total of 76 patients with poor bilateral upper eyelid morphology or a single eyelid were included in this study. Different techniques of double-eyelid blepharoplasty were performed based on the thickness of the palpebral tissue. The improved PARK method (group A: 15 participants) was employed for patients with orbicularis oculi muscle being thinner, and the fat bulge of orbital septum was less. The improved traditional method (group B: 52 participants) was employed for patients with hypertrophy of the eyelid skin, orbicularis oculi muscle, and fat bulge in the orbital septum. RESULTS: All 76 patients achieved satisfactory outcomes in a single surgical procedure. Postoperative follow-up ranged from 3 to 6 months. In group A, there was no obvious swelling of flap near the palpebral margin and the double blepharon line becomes shallow. Although some patients in group B experienced varying degrees of bruising in the early postoperative period, all patients returned to a more natural shape 1-3 months after surgery. Furthermore, after 3-6 months postoperatively, there were no obvious scar adhesion and ladder sensation in the both sides of the incision. CONCLUSION: Preoperative analysis of the thickness of the upper eyelid tissue is essential to determine the appropriate surgical technique for double-eyelid blepharoplasty. The improved traditional method is recommended for patients with hypertrophy of the upper eyelid tissue (group A), as it minimizes scar adhesion and reduces the stair-step sensation in the lower eyelid tissue during long-term follow-up. For patients with thin upper eyelid tissue, the improved PARK method should be employed to avoid issues such as tissue accumulation, double eyelid crease became shallower, or disappearance. In order to obtain natural and long-term surgical results, different surgical methods should be provided according to the patient's eye tissue condition.

RESUMEN

BACKGROUND: Japan has a shortage of childcare personnel, and the high levels of stress causing turnover in childcare workers must be urgently resolved. However, there is a lack of knowledge regarding the characteristics and influencing factors of job stress in Japanese childcare workers. OBJECTIVE: This study aimed to evaluate the job stress of childcare workers and explore the influence of demographic factors and the COVID-19 pandemic on such stress. METHODS: The data were collected through an Internet survey from 2,472 respondents. A 23-item version of the Brief Job Stress Questionnaire was used to measure occupational stress in childcare workers. The instrument is recommended in the stress-check program implemented as a mental health measure in workplaces in Japan. RESULTS: The percentage of childcare workers with high stress exceeded that of general workers. Multiple regression analyses showed that the only factor affecting all job stressors and social support was the fear of contracting COVID-19. Job stressors and the COVID-19 pandemic had a significant large effect on stress responses. Additionally, being married and having children moderated childcare workers' stress. CONCLUSIONS: This study provided basic data regarding job stress in Japanese childcare workers and compared them with those of other professionals. In the future, it will be necessary to clarify how stress is related to turnover intention and turnover in Japanese childcare workers to promote their career continuity.

RESUMEN

IMPORTANCE: COVID-19 has disproportionately affected racialized populations, with particular impact among individuals of Black individuals. However, it is unclear whether disparities in venous thromboembolic (VTE) complications exist between Black individuals and those belonging to other racial groups with confirmed SARS-CoV2 infections. OBJECTIVE: To summarize the prevalence and moderators associated with VTE among Black COVID-19 patients in minoritized settings, and to compare this to White and Asian COVID-19 patients according to sex, age, and comorbid health conditions (heart failure, cancer, obesity, hypertension). DESIGN SETTING, AND PARTICIPANTS: A systematic search of MEDLINE, Embase, CINAHL and CENTRAL for articles or reports published from inception to February 15, 2023. STUDY SELECTION: Reports on VTE among Black individuals infected with SARS-CoV2, in countries where Black people are considered a minority population group. DATA EXTRACTION AND SYNTHESIS: Study characteristics and results of eligible studies were independently extracted by 2 pairs of reviewers. VTE prevalence was extracted, and risk of bias was assessed. Prevalence estimates of VTE prevalence among Black individuals with COVID19 in each study were pooled. Where studies provided race-stratified VTE prevalence among COVID19 patients, odds ratios were generated using a random-effects model. MAIN OUTCOMES AND MEASURES: Prevalence of VTE, comprising of deep vein thrombosis and pulmonary embolism. RESULTS: Ten studies with 66,185 Black individuals reporting the prevalence of COVID-19 associated VTE were included. Weighted median age of included studies was 47.60. Pooled prevalence of COVID-19 associated VTE was 7.2 % (95 % CI, 3.8 % - 11.5 %) among Black individuals. Among individuals with SARS-CoV2 infections, Black population had higher risks of VTE compared to their White (OR = 1.79, [95 % CI 1.28-2.53], p < .001) or Asian (OR = 2.01, [95 % CI, 1.14-3.60], p = .017) counterparts, or patients with other racial identities (OR = 2.01, [95 % CI, 1.39, 2.92]; p < .001). CONCLUSIONS AND RELEVANCE: Black individuals with COVID-19 had substantially higher risk of VTE compared to White or Asian individuals. Given racial disparities in thrombotic disease burden related to COVID-19, medical education, research, and health policy interventions are direly needed to ensure adequate disease awareness among Black individuals, to facilitate appropriate diagnosis and treatment among Black patients with suspected and confirmed VTE, and to advocate for culturally safe VTE prevention strategies, including pre-existing inequalities to the COVID-19 pandemic that persist after the crisis.

RESUMEN

PURPOSE: Carfilzomib, commonly used for relapsed/refractory multiple myeloma (RRMM), has been associated with various adverse events in randomized controlled trials (RCTs). However, real-world safety data for a more diverse population are needed, as carfilzomib received expedited approval. This study aimed to evaluate carfilzomib's safety in Korea by comparing new users of KRd (carfilzomib, lenalidomide, and dexamethasone) to Rd (lenalidomide and dexamethasone) using a nationwide administrative claims database. METHODS: The retrospective cohort study utilized target trial emulation, focusing on adverse events in various organ systems similar to the ASPIRE trial. RESULTS: This study included 4,580 RRMM patients between 2007 and 2020, and the KRd group showed significantly higher risks of hematologic adverse events (anemia, neutropenia, thrombocytopenia) and some non-hematologic adverse events (cough, hypokalemia, constipation, hypertension, heart failure) compared to the Rd group. Among non-hematologic adverse events, cardiovascular events (heart failure [HR 2.04; 95% CI 1.24-3.35], hypertension [HR 1.58; 95% CI 1.15-2.17]) had the highest risk in the KRd group. CONCLUSION: The safety profile of carfilzomib in Korean patients was similar to previous RCTs. Therefore, caution should be exercised when using carfilzomib in Asian individuals with RRMM due to the increased risk of cardiovascular adverse events.

RESUMEN

INTRODUCTION: Passive smoking is considered a major public health issue in China. Prospective evidence regarding the link between secondhand smoke (SHS) and ischemic stroke in China is scarce. METHODS: The China Kadoorie Biobank (CKB) study in Liuzhou City recruited 50,174 participants during 2004-2008. Of these 30,456 never-smokers were included in our study. The median follow-up period was 10.7 years. The incidence of ischemic stroke was obtained through the China Disease Surveillance Points (DSP) system and the Health Insurance (HI) database. Cox proportional risk models were used to evaluate the association between SHS exposure and ischemic stroke. RESULTS: During 320,678 person-years of follow-up, there were 2059 patients with ischemic stroke observed and the incidence of ischemic stroke was 6.42 per thousand person-years. Participants exposed to SHS daily faced a 21 % higher risk of ischemic stroke (HR = 1.21, 95 %CI: 1.09-1.34) compared to those exposed to SHS less than once a week. Subgroup analyses revealed that daily SHS exposure was linked to heightened risk of ischemic stroke among women, non-employed, and non-weekly tea drinkers. CONCLUSIONS: Daily SHS exposure was associated with higher risks of ischemic stroke. Proactive tobacco control strategies are necessary to decrease the risk of ischemic stroke in never smokers.

RESUMEN

BACKGROUND: Asian people in the United States have different sociodemographic and health-related characteristics that might affect cardiovascular disease (CVD) risk by ethnicity and birthplace. However, they are often studied as a monolithic group in health care research. This study aimed to examine heterogeneity in CVD risk factors on the basis of birthplace among the 3 largest Asian subgroups (Chinese, Asian Indian, and Filipino) compared with US-born non-Hispanic White (NHW) adults. METHODS AND RESULTS: A cross-sectional analysis was conducted using the 2010 to 2018 National Health Interview Survey data from 125 008 US-born and foreign-born Chinese, Asian Indian, Filipino, and US-born NHW adults. Generalized linear models with Poisson distribution were used to examine the prevalence and prevalence ratios of self-reported hypertension, diabetes, high cholesterol, physical inactivity, smoking, and overweight/obesity among Asian subgroups compared with US-born NHW adults. The study included 118 979 US-born NHW and 6029 Asian adults who self-identified as Chinese (29%), Asian Indian (33%), and Filipino (38%). Participants' mean (±SD) age was 49±0.1 years, and 53% were females. In an adjusted analysis, foreign-born Asian Indians had significantly higher prevalence of diabetes, physical inactivity, and overweight/obesity; foreign-born Chinese had higher prevalence of physical inactivity, and foreign-born Filipinos had higher prevalence of all 5 CVD risk factors except smoking compared with NHW adults. CONCLUSIONS: This study revealed significant heterogeneity in the prevalence of CVD risk factors among Asian subgroups by ethnicity and birthplace, stressing the necessity of disaggregating Asian subgroup data. Providers should consider this heterogeneity in CVD risk factors and establish tailored CVD prevention plans for Asian subgroups.

RESUMEN

Introduction: Previous studies have demonstrated associations between sex and racialized group on pain sensitivity and tolerance. We analyzed the association of sex and racialized group on heat pain sensitivity, sensibility to painful suprathreshold mechanical pain (STMP), and pain sensitivity questionnaire (PSQ). We hypothesized that anxiety and pain catastrophizing reported by racialized minority groups and women would mediate enhanced pain sensitivity. Our secondary aim was to evaluate validity of the PSQ in a diverse population. Methods: Using quantitative sensory testing for painful heat, STMP (forces: 64, 128, 256, and 512 mN), and PSQ, we evaluated pain sensitivity in 134 healthy participants [34 (18 women) Asian, 25 (13 women) Black, and 75 (41 women) White]. We used general linear and linear mixed models to analyze outcomes. We assessed mediation of state and trait anxiety and pain catastrophizing on pain sensitivity. Results: Racialized minority status was associated with greater heat pain sensitivity (F = 7.63; P = 0.00074) and PSQ scores (F = 15.45; P = 9.84 × 10-7) but not associated with STMP (F = 1.50; P = 0.23). Female sex was associated with greater heat pain sensitivity (F = 4.9; P = 0.029) and lower PSQ (F = 9.50; P = 0.0025) but not associated with STMP (F = 0.0018; P = 0.97). Neither anxiety nor pain catastrophizing mediated associations between sex or racialized group with heat pain threshold or PSQ. Differential experience of individual items (F = 19.87; P = 3.28 × 10-8) limited PSQ face validity in racialized minorities. Conclusion: Consistent with previous research, sensitivity to painful heat was associated with racialized minority status and female sex. By contrast, there was no significant effect of racialized minority status or female sex on STMP. Some PSQ items are inapplicable to participants from racialized minority groups.

RESUMEN

Hypertriglyceridemia and decreased high-density lipoprotein cholesterol (HDL-C) persist despite statin therapy, contributing to residual atherosclerotic cardiovascular disease (ASCVD) risk. Asian subjects are metabolically more susceptible to hypertriglyceridemia than other ethnicities. Fenofibrate regulates hypertriglyceridemia, raises HDL-C levels, and is a recommended treatment for dyslipidemia. However, data on fenofibrate use across different Asian regions are limited. This narrative review summarizes the efficacy and safety data of fenofibrate in Asian subjects with dyslipidemia and related comorbidities (diabetes, metabolic syndrome, diabetic retinopathy, and diabetic nephropathy). Long-term fenofibrate use resulted in fewer cardiovascular (CV) events and reduced the composite of heart failure hospitalizations or CV mortality in type 2 diabetes mellitus. Fenofibrate plays a significant role in improving irisin resistance and microalbuminuria, inhibiting inflammatory responses, and reducing retinopathy incidence. Fenofibrate plus statin combination significantly reduced composite CV events risk in patients with metabolic syndrome and demonstrated decreased triglyceride and increased HDL-C levels with an acceptable safety profile in those with high CV or ASCVD risk. Nevertheless, care is necessary with fenofibrate use due to possible hepatic and renal toxicities in vulnerable individuals. Long-term trials and real-world studies are needed to confirm the clinical benefits of fenofibrate in the heterogeneous Asian population with dyslipidemia.

RESUMEN

OBJECTIVES: To describe the clinical characteristics of Chinese cystic fibrosis (CF) patients and to investigate the variants of CFTR and their potential pathogenicity. STUDY DESIGN: Chinese patients with potential CF diagnosis were studied. Clinical data were reviewed retrospectively from medical records. Whole exome sequencing and genetic evaluation were conducted to explore potential gene variants. The disruption of the variants to protein structure and function was explored and validated using in vitro experiments and in silico analysis. RESULTS: Four patients were recruited to the study, three of them were diagnosed as CF, and one was diagnosed as CFTR-related disorder. The age at symptom onset for the patients in this study ranged from newborn to 6 years, while the age at diagnosis varied from 3 to 11 years. All four patients exhibited bilateral diffuse bronchiectasis with Pseudomonas aeruginosa infections, and three of them had malnutrition. Finger clubbing was observed in three patients, two of whom displayed mixed ventilatory dysfunction. The CFTR variants spectrum of Chinese children with CF differs from that of Caucasian. A total of six variants were identified, two of which were first reported (c.1219G > T [p.Glu407*] and c.1367delT [p.Ala457Leufs*12]). The nonsense variants c.1219G > T, c.1657C > T and c.2551C > T and the frameshift variant c.1367delT were predicted to introduce premature stop codon and produce shorten CFTR protein, which was also first validated by in vitro truncation assay in this study. The missense variant c.1810A > C was predicted to disrupt the function of the nucleotide-binding domain 1 (NBD1) in the CFTR protein. The splicing variant c.1766 + 5G > T caused skipping of exon 13 and damaged the integrity of CFTR protein. CONCLUSIONS: Our study expands the spectrum of phenotypes and genotypes for CF of Chinese origin, which differs significantly from that of Caucasian. Genetic analysis and counseling are crucial and deserve extensive popularization for the diagnosis ofCF in patients of Chinese origin.

RESUMEN

OBJECTIVES: This study aims to evaluate the endocrine differences among polycystic ovary syndrome (PCOS) phenotypes in Japanese women. METHODS: 118 Japanese women that we diagnosed with PCOS agreed to be included in the study. The study group was classified into the following 4 phenotypes: (A) hyperandrogenism (HA); ovulatory disorder (OvD) and polycystic ovary morphology (PCOM); (B) HA and OvD; (C) HA and PCOM; and (D) OvD and PCOM. We also recruited 66 healthy Japanese women to the study as control participants. Age, body mass index, androgens, luteinizing hormone, follicle-stimulating hormone, and insulin resistance (IR) index were evaluated and compared. RESULTS: The proportions of phenotypes A, B, C, and D were 57/120 (47.5%), 4/120 (3.3%), 13/120 (10.8%), and 46/120 (38.3%), respectively. The proportion of phenotype B was too small; therefore, phenotypes A and B were grouped as classical PCOS for intergroup comparisons. The luteinizing hormone/follicle-stimulating hormone ratio in the classical PCOS group was higher than that in the phenotype D group (P < 0.001). Androgen concentrations in the phenotype D group were significantly lower than those in the other groups (P < 0.01). Phenotype D was more common in lean women with PCOS. The surrogate marker of IR (homeostasis model assessment of IR) was not different irrespective of PCOS and its phenotypes. CONCLUSIONS: Except for androgens, endocrine differences by PCOS phenotype are not evident, suggesting that diversity among patients with PCOS is relatively low in Japanese women.

RESUMEN

AIM: To explain the process taken by Chinese family care partners of older adults in the Greater Toronto Area, Canada, to access health and social services in their communities. The research question was: What mechanisms and structures impact the agency of Chinese family care partners of older adults, in the process of assisting them to access health and social services? DESIGN: This qualitative study was informed by critical realism. METHODS: Chinese family care partners of older adults in the Greater Toronto Area, Canada, were interviewed from August 2020 to June 2021. Transcripts underwent thematic analysis. FINDINGS: Twenty-eight Chinese family care partners expressed a firm commitment to maintain caregiving conditions and to judiciously access health and social services. Their commitment was made up of three parts: (a) legislative and cultural norms of family, work, and society; (b) their perseverance to fill gaps with limited social and financial resources; (c) the quality of their relationship to, and illness trajectory of the older adults. The social structures created tension in how Chinese family care partners made decisions, negotiated resources, and ultimately monitored and coordinated timely access with older adults. CONCLUSION: Participants' commitment and perseverance were conceptualized as "grit," central to their agency to conform to legislative and cultural norms. Moreover, findings support grit's power to motivate and sustain family caregiving, in order for older adults to age in place as long as possible with finite resources. IMPLICATIONS FOR THE PROFESSION: This study highlights the importance of cultural awareness education for nurses, enabling continuity of care at a systems level and for a more resilient healthcare system. IMPACT: Family care partners' grit may be crucial for nurses to harness when together, they face limited access to culturally appropriate health and social services in a system grounded in values of equity and inclusion, as in Canada. REPORTING METHOD: When writing this manuscript, we adhered to relevant EQUATOR guidelines of the Consolidated Criteria for Reporting Qualitative Research (COREQ). PATIENT OR PUBLIC INVOLVEMENT AND ENGAGEMENT: No patient or public involvement.

RESUMEN

Modified maxillomandibular advancement (MMMA) has been proposed as an alternative to the classic maxillomandibular advancement (MMA) in East and Southeast Asian populations in which bimaxillary protrusion is a prevalent trait. The key difference between MMMA and MMA is the inclusion of anterior segmental osteotomies to reduce the protrusion of the perioral region. The aim of this scoping review was to identify the variations in MMMA and treatment outcomes. A search was conducted in the PubMed, Embase, and Cochrane electronic databases for articles published up to January 2023. Ten articles were included in this review. Three variations of MMMA have been reported in the literature. Treatment outcomes have mostly been favourable for all of these variations. Mandibular advancement of >10 mm and a greater than 50% reduction in the apnoea-hypopnoea index (AHI) have been well reported. Improvements in other outcome measures, such as enlargement of the airway dimension on computed tomography and the Epworth Sleepiness Scale score, have also been shown. Despite additional surgical procedures, complications have been uncommon and mostly minor in nature. It is necessary to be cognizant of MMMA and its variations when providing sleep surgery for East and Southeast Asian patients, tailoring this to the patient's profile and needs.

RESUMEN

BACKGROUND: Although many observational studies have demonstrated significant relationships between obesity and cardiometabolic traits, the causality of these relationships in East Asians remains to be elucidated. METHODS: We conducted individual-level Mendelian randomization (MR) analyses targeting 14,083 participants in the Japan Multi-Institutional Collaborative Cohort Study and two-sample MR analyses using summary statistics based on genome-wide association study data from 173,430 Japanese. Using 83 body mass index (BMI)-related loci, genetic risk scores (GRS) for BMI were calculated, and the effects of BMI on cardiometabolic traits were examined for individual-level MR analyses using the two-stage least squares estimator method. The ß-coefficients and standard errors for the per-allele association of each single-nucleotide polymorphism as well as all outcomes, or odds ratios with 95% confidence intervals were calculated in the two-sample MR analyses. RESULTS: In individual-level MR analyses, the GRS of BMI was not significantly associated with any cardiometabolic traits. In two-sample MR analyses, higher BMI was associated with increased risks of higher blood pressure, triglycerides, and uric acid, as well as lower high-density-lipoprotein cholesterol and eGFR. The associations of BMI with type 2 diabetes in two-sample MR analyses were inconsistent using different methods, including the directions. CONCLUSION: The results of this study suggest that, even among the Japanese, an East Asian population with low levels of obesity, higher BMI could be causally associated with the development of a variety of cardiometabolic traits. Causality in those associations should be clarified in future studies with larger populations, especially those of BMI with type 2 diabetes.

RESUMEN

Objectives: To gain insight in the motives and determinants for the uptake of healthy lifestyles by South-Asian Surinamese people to identify needs and engagement strategies for healthy lifestyle support. Methods: We used a mixed-method design: first, focus groups with South-Asian Surinamese women; second, a questionnaire directed at their social network, and third, interviews with health professionals. Qualitative content analysis, basic statistical analyses and triangulation of data were applied. Results: Sixty people participated (n = 30 women, n = 20 social network, n = 10 professionals). Respondent groups reported similar motives and determinants for healthy lifestyles. In general, cardiometabolic prevention was in line with the perspectives and needs of South-Asian Surinamese. However, there seems to be a mismatch too: South-Asian Surinamese people missed a culturally sensitive approach, whereas professionals experienced difficulty with patient adherence. Incremental changes to current lifestyles; including the social network, and an encouraging approach seem to be key points for improvement of professional cardiometabolic prevention. Conclusion: Some key points for better culturally tailoring of preventive interventions would meet the needs and preferences of the South-Asian Surinamese living in the Netherlands.

RESUMEN

Objective: The study design included the double-blind, parallel, randomized controlled trial. The aim of this randomized controlled trial was to compare the efficacy and safety of sertraline and escitalopram in participants with moderate to severe major depressive disorder (MDD). Methods: The study was conducted in South Asian participants. A total of 744 participants with moderate to severe MDD were randomly assigned to receive either sertraline or escitalopram for 8 weeks. Drug dosages and titration schedules were based on the recommendations of the prescribing information for each product and according to the judgment of the clinicians involved in the study. The primary outcome measures were changes from baseline on the Montgomery-Åsberg Depression Rating Scale (MADRS) and the clinical global impression (CGI) scale as well as the frequency of adverse events in both groups. Baseline MADRS scores in the escitalopram and sertraline groups were 28.2±0.47 (mean±SD) and 29.70±0.46 (mean±SD) respectively, and was no variability in the baseline assessments. Changes in MADRS as well as CGI scales at the end of the study were significant only for the sertraline group whereas they remained statistically nonsignificant for the escitalopram group. Results: The results of the study showed that sertraline was more efficacious than escitalopram in reducing depression rating scales such as MADRS and CGI, and that participants subjectively felt better regarding their symptoms in the sertraline group. Sertraline displays enhanced safety or tolerability than other groups of antidepressants, which frequently cause high levels of drowsiness, dizziness, blurred vision, and other undesirable effects. Adverse events were seen in both groups, but delayed ejaculation was the most frequent adverse event seen in both groups. However, a greater number of participants reported having nausea and insomnia in the sertraline group compared to the escitalopram group. Conclusion: Our study clearly highlights that there is a statistically significant difference in efficacy between sertraline and escitalopram at the doses used in our study. Sertraline was able to significantly lower the depression rating scales like MADRS and CGI in participants with moderate to severe MDD. Participants subjectively felt better regarding their symptoms in the sertraline group. The most frequent adverse event in both groups was delayed ejaculation. From an efficacy standpoint, sertraline was more efficacious than escitalopram. The study indicates that the prevalence of depressive disorders in South Asia is comparable to the global estimate, and Bangladesh and India has higher proportions of people with depressive disorders in South Asia. Additionally, females and older adults (75-79 years) have the highest burden of depressive disorders across all countries in the region. This study's limitation included the absence of a placebo arm. An additional limitation of the current study was the lack of an evaluation of inter-rater reliability and the research sample could not have been uniform in terms of the kind of depressive disorders and bipolarity.

RESUMEN

OBJECTIVES: To systematically synthesize the views of community-dwelling Asians on Advance care planning and to summarize the factors and reasons affecting their uptake of ACP. DESIGN: Mixed-methods systematic review (PROSPERO: CRD42018091033). SETTING AND PARTICIPANTS: Asian adults (≥18 years old) living in the community globally. METHODS: Medline (Ovid), Web of Science, CINAHL (EBSCO), Open Grey, and Google Scholar were searched from inception to June 30, 2022. Qualitative, quantitative, or mixed-methods studies reporting on the views of non-seriously ill community-dwelling Asian adults on ACP or the factors influencing their ACP uptake were included. Secondary research, studies not published in English, or studies not available as full text were excluded. Two independent teams of researchers extracted data, assessed methodologic quality, and performed the data analysis. Data analysis was conducted using the multistep convergent integrated approach based on Joanna Briggs Institute methodology for mixed-methods systematic review. RESULTS: Fifty-eight studies were included. Non-seriously ill community-dwelling Asians were willing to engage in ACP (46.5%-84.4%) although their awareness (3.1%-42.9%) and uptake of ACP remained low (14.0%-53.4%). Background factors (sociodemographic factors, and health status, as well as experience and exposure to information) and underlying beliefs (attitude toward ACP, subjective norm, and perceived behavioral control) were found to affect their uptake of ACP. A conceptual framework was developed to facilitate a proper approach to ACP for this population. CONCLUSIONS AND IMPLICATIONS: A flexible approach toward ACP is needed for non-seriously ill community-dwelling Asians. There is also a need to raise end-of-life and ACP literacy, and to explore ways to narrow the gap in the expectations and implementation of ACP so that trust in its effective execution can be built.

RESUMEN

BACKGROUND: Geographical (geospatial) clusters have been observed in inflammatory bowel disease (IBD) incidence and linked to environmental determinants of disease, but pediatric spatial patterns in North America are unknown. We hypothesized that we would identify geospatial clusters in the pediatric IBD (PIBD) population of British Columbia (BC), Canada and associate incidence with ethnicity and environmental exposures. AIM: To identify PIBD clusters and model how spatial patterns are associated with population ethnicity and environmental exposures. METHODS: One thousand one hundred eighty-three patients were included from a BC Children's Hospital clinical registry who met the criteria of diagnosis with IBD ≤ age 16.9 from 2001-2016 with a valid postal code on file. A spatial cluster detection routine was used to identify areas with similar incidence. An ecological analysis employed Poisson rate models of IBD, Crohn's disease (CD), and ulcerative colitis (UC) cases as functions of areal population ethnicity, rurality, average family size and income, average population exposure to green space, air pollution, and vitamin-D weighted ultraviolet light from the Canadian Environmental Health Research Consortium, and pesticide applications. RESULTS: Hot spots (high incidence) were identified in Metro Vancouver (IBD, CD, UC), southern Okanagan regions (IBD, CD), and Vancouver Island (CD). Cold spots (low incidence) were identified in Southeastern BC (IBD, CD, UC), Northern BC (IBD, CD), and on BC's coast (UC). No high incidence hot spots were detected in the densest urban areas. Modeling results were represented as incidence rate ratios (IRR) with 95%CI. Novel risk factors for PIBD included fine particulate matter (PM2.5) pollution (IRR = 1.294, CI = 1.113-1.507, P < 0.001) and agricultural application of petroleum oil to orchards and grapes (IRR = 1.135, CI = 1.007-1.270, P = 0.033). South Asian population (IRR = 1.020, CI = 1.011-1.028, P < 0.001) was a risk factor and Indigenous population (IRR = 0.956, CI = 0.941-0.971, P < 0.001), family size (IRR = 0.467, CI = 0.268-0.816, P = 0.007), and summer ultraviolet (IBD = 0.9993, CI = 0.9990-0.9996, P < 0.001) were protective factors as previously established. Novel risk factors for CD, as for PIBD, included: PM2.5 air pollution (IRR = 1.230, CI = 1 .056-1.435, P = 0.008) and agricultural petroleum oil (IRR = 1.159, CI = 1.002-1.326, P = 0.038). Indigenous population (IRR = 0.923, CI = 0.895-0.951, P < 0.001), as previously established, was a protective factor. For UC, rural population (UC IRR = 0.990, CI = 0.983-0.996, P = 0.004) was a protective factor and South Asian population (IRR = 1.054, CI = 1.030-1.079, P < 0.001) a risk factor as previously established. CONCLUSION: PIBD spatial clusters were identified and associated with known and novel environmental determinants. The identification of agricultural pesticides and PM2.5 air pollution needs further study to validate these observations.
