Perceived Stress and Interest in Non-Invasive Aesthetic Procedures During the COVID-19 Pandemic.

Purpose: Multiple effects of the COVID-19 pandemic have been described, including an increase in concerns about one's facial appearance resulting in greater interest in cosmetic procedures. However, additional research is required to examine the impact of the pandemic on patients' overall stress levels and whether this reported stress is associated with an interest in facial aesthetic procedures. We aimed to describe perceived stress and to identify factors associated with increased stress among patients seeking aesthetic treatments during the pandemic. Patients and Methods: Patients coming to a Singapore-based clinic and who completed a questionnaire over a one-month period were included. Stress was evaluated using the Perceived Stress Scale (PSS); additional questions sought to understand factors associated with perceived stress and future interest in aesthetic procedures. Results: Two hundred and thirteen respondents participated in the study. Separation from family and inability to travel for leisure were major stressors in 54% and 55%; getting COVID-19 was less frequently a stressor (11%). Patients reported greater concern with appearance (increased worry in 32%, comparison to others in 41%). Ninety-one percent of patients continued aesthetic procedures despite the pandemic and 75% reported interest in proceeding with treatments not previously tried before. PSS scores were higher than published norms. Factors associated with increased scores included residency status, job insecurity and markers of increased concern about appearance. Finally, higher stress scores were observed in patients with greater likelihood of receiving future aesthetic treatments, although this was not statistically significant after applying the Bonferroni correction for multiple comparisons. Conclusion: Significantly higher stress scores were seen in patients seeking aesthetic treatments. We identified factors associated with increased stress with a suggested association between increased likelihood of proceeding with any aesthetic procedure and higher levels of stress. These highlight the importance of caution in treating patients given their increased stress levels and potential vulnerability.

Characteristics of Patients Seeking and Proceeding with Non-Surgical Facial Aesthetic Procedures.

PURPOSE: Identifying predictors for patients' readiness to receive non-surgical facial aesthetic treatments facilitates the physician's understanding of the patient's goals and expectations. This paper aims to identify clinical and demographic characteristics of patients who proceed with non-surgical facial aesthetic procedures in Singapore. PATIENTS AND METHODS: Using data from electronic patient health records, authors examined clinical and demographic characteristics of 624 Asian and Caucasian patients who sought treatment in a 12-month period and who had minimum follow-up of 1 year. Variables examined included age, race/ethnicity, gender, prior treatment, and attitudes and motivation for seeking treatment. Univariate and multivariate analyses of factors associated with proceeding with the treatment plan were evaluated using chi-square and logistic regression analyses. RESULTS: Approximately 88% of patients who sought consultation proceeded with treatment. The majority were older than 40 years of age, were female and received prior treatments. Notable is the high frequency of rejuvenation rather than correction as the clinical outcome goal. There were slightly more Caucasians than Chinese patients but the racial distribution allowed the identification of differences between the two groups. Chinese patients were younger and more likely to seek correction or more obvious changes as compared to Caucasian patients. On multivariate analyses, powerful predictors for proceeding with non-invasive facial treatments included a treatment goal of rejuvenation rather than correction, an expectation of an immediate result, and prior aesthetic treatments. CONCLUSION: This study is the first to compare race/ethnic differences in factors that influence treatment with non-invasive aesthetic procedures. This is also the first to identify demographic, clinical and motivational characteristics associated with actual treatment with non-invasive facial procedures. Further research on a systematic approach to defining a patient's motivation for receiving treatment, as well as research identifying which patients are more likely to have positive clinical outcomes are warranted.

Sex-specific differences in hemodialysis prevalence and practices and the male-to-female mortality rate: the Dialysis Outcomes and Practice Patterns Study (DOPPS).

BACKGROUND: A comprehensive analysis of sex-specific differences in the characteristics, treatment, and outcomes of individuals with end-stage renal disease undergoing dialysis might reveal treatment inequalities and targets to improve sex-specific patient care. Here we describe hemodialysis prevalence and patient characteristics by sex, compare the adult male-to-female mortality rate with data from the general population, and evaluate sex interactions with mortality. METHODS AND FINDINGS: We assessed the Human Mortality Database and 206,374 patients receiving hemodialysis from 12 countries (Australia, Belgium, Canada, France, Germany, Italy, Japan, New Zealand, Spain, Sweden, the UK, and the US) participating in the international, prospective Dialysis Outcomes and Practice Patterns Study (DOPPS) between June 1996 and March 2012. Among 35,964 sampled DOPPS patients with full data collection, we studied patient characteristics (descriptively) and mortality (via Cox regression) by sex. In all age groups, more men than women were on hemodialysis (59% versus 41% overall), with large differences observed between countries. The average estimated glomerular filtration rate at hemodialysis initiation was higher in men than women. The male-to-female mortality rate ratio in the general population varied from 1.5 to 2.6 for age groups <75 y, but in hemodialysis patients was close to one. Compared to women, men were younger (mean = 61.9 ± standard deviation 14.6 versus 63.1 ± 14.5 y), were less frequently obese, were more frequently married and recipients of a kidney transplant, more frequently had coronary artery disease, and were less frequently depressed. Interaction analyses showed that the mortality risk associated with several comorbidities and hemodialysis catheter use was lower for men (hazard ratio [HR] = 1.11) than women (HR = 1.33, interaction p<0.001). This study is limited by its inability to establish causality for the observed sex-specific differences and does not provide information about patients not treated with dialysis or dying prior to a planned start of dialysis. CONCLUSIONS: Women's survival advantage was markedly diminished in hemodialysis patients. The finding that fewer women than men were being treated with dialysis for end-stage renal disease merits detailed further study, as the large discrepancies in sex-specific hemodialysis prevalence by country and age group are likely explained by factors beyond biology. Modifiable variables, such as catheter use, showing significant sex interactions suggest interventional targeting. Please see later in the article for the Editors' Summary.

Two-times weekly hemodialysis in China: frequency, associated patient and treatment characteristics and Quality of Life in the China Dialysis Outcomes and Practice Patterns study.

BACKGROUND: Renal replacement therapy is rapidly expanding in China, and two-times weekly dialysis is common, but detailed data on practice patterns are currently limited. Using cross-sectional data from the China Dialysis Outcomes and Practice Patterns Study (DOPPS), we describe the hemodialysis practice in China compared with other DOPPS countries, examining demographic, social and clinical characteristics of patients on two-times weekly dialysis. METHODS: The DOPPS protocol was implemented in 2011 among a cross-section of 1379 patients in 45 facilities in Beijing, Guangzhou and Shanghai. Data from China were compared with a cross section of 11 054 patients from the core DOPPS countries (collected 2009-11). Among China DOPPS patients, logistic and linear regression were used to describe the association of dialysis frequency with patient and treatment characteristics and quality of life. RESULTS: A total of 26% of the patients in China were dialyzing two times weekly, compared with < 5% in other DOPPS regions. Standardized Kt/V was lowest in China (2.01) compared with other regions (2.12-2.27). Female sex, shorter dialysis vintage, lower socioeconomic status, less health insurance coverage, and lack of diabetes and hypertension were associated with dialyzing two times weekly (versus three times weekly). Patients dialyzing two times per week had longer treatment times and lower standardized Kt/V, but similar quality of life scores. CONCLUSIONS: Two-times weekly dialysis is common in China, particularly among patients, who started dialysis more recently, have a lower comorbidity burden and have financial constraints. Quality of life scores do not differ between the two-times and three-times weekly groups. The effect on clinical outcomes merits further study.

Association between oral nutritional supplementation and clinical outcomes among patients with ESRD.

BACKGROUND AND OBJECTIVES: Oral nutritional supplementation (ONS) was provided to ESRD patients with hypoalbuminemia as part of Fresenius Medical Care Health Plan's (FMCHP) disease management. This study evaluated the association between FMCHP's ONS program and clinical outcomes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Analyses included FMCHP patients with ONS indication (n=470) defined as 2-month mean albumin <3.8 g/dl until reaching a 3-month mean ≥3.8 g/dl from February 1, 2006 to December 31, 2008. Patients did not receive ONS if deemed inappropriate or refused. Patients on ONS were compared with patients who were not, despite meeting ONS indication. Patients with ONS indication regardless of use were compared with Medicare patients with similar serum albumin levels from the 2007 Centers for Medicare and Medicaid Services Clinical Performance Measures Project (CPM). Cox models calculated adjusted hospitalization and mortality risks at 1 year. RESULTS: Among patients with indication for ONS, 276 received supplements and 194 did not. ONS use was associated with 0.058 g/dl higher serum albumin overall (P=0.02); this difference decreased by 0.001 g/dl each month (P=0.05) such that the difference was 0.052 g/dl (P=0.04) in month 6 and the difference was no longer significant in month 12 . In analyses based on ONS use, ONS patients had lower hospitalization at 1 year (68.4%; P<0.01) versus patients without ONS (88.7%), but there was no significant reduction in mortality risk (P=0.29). In analyses based on ONS indication, patients with indication had lower mortality at 1 year (16.2%) compared with CPM patients (23.4%; P<0.01). CONCLUSIONS: These findings suggest that ONS use was associated with significantly lower hospitalization rates but had no significant effect on mortality in a disease management setting.

Physical exercise among participants in the Dialysis Outcomes and Practice Patterns Study (DOPPS): correlates and associated outcomes.

BACKGROUND: Levels of physical exercise among haemodialysis patients are low. Increased physical activity in this population has been associated with improved health-related quality of life (HRQoL) and survival. However, results of previous studies may not be applicable to the haemodialysis population as a whole. The present study provides the first description of international patterns of exercise frequency and its association with exercise programmes and clinical outcomes among participants in the Dialysis Outcomes and Practice Patterns Study (DOPPS). METHODS: Data from a cross section of 20,920 DOPPS participants in 12 countries between 1996 and 2004 were analysed. Regular exercise was defined as exercise frequency equal to or more than once/week based on patient self-report. Linear mixed models and logistic regression assessed associations of exercise frequency with HRQoL and other psychosocial variables. Mortality risk was calculated in Cox proportional hazard models using patient-level (patient self-reported exercise frequency) and facility-level (the dialysis facility percentage of regular exercisers) predictors. RESULTS: Regular exercise frequency varied widely across countries and across dialysis facilities within a country. Overall, 47.4% of participants were categorized as regular exercisers. The odds of regular exercise was 38% higher for patients from facilities offering exercise programmes (adjusted odds ratio = 1.38 [95% confidence interval: 1.03-1.84]; P = 0.03). Regular exercisers had higher HRQoL, physical functioning and sleep quality scores; reported fewer limitations in physical activities; and were less bothered by bodily pain or lack of appetite (P

Prescription of antihypertensive agents to haemodialysis patients: time trends and associations with patient characteristics, country and survival in the DOPPS.

BACKGROUND: Haemodialysis patients were studied in 12 countries to identify practice patterns of prescription of antihypertensive agents (AHA) associated with survival. METHODS: The sample included 28 513 patients enrolled in DOPPS I and II. The classes of AHA studied were beta blocker (BB), angiotensin-converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), peripheral blocker, central antagonist, vasodilator, long-acting dihydropyridine calcium channel blocker (CCB), short-acting dihydropyridine CCB and non-dihydropyridine CCB. To reduce bias due to unmeasured confounders, the associations with mortality were assessed by separate Cox models based on patient-level prescription and facility prescription practice. RESULTS: An increase in prescription of ARBs (9.5%) and BBs (9.1%) was observed from DOPPS I to II. Prescription of AHA classes varied significantly by country, ranging for BBs from 9.7% in Japan to 52.7% in Sweden and for ARBs from 5.5% in Italy to 21.3% in Japan in DOPPS II. Facilities that treated 10% more patients with ARBs had, on average, 7% lower all-cause mortality, independent of patient characteristics and the prescription patterns of other antihypertensive medications (P = 0.05). Significant and independent associations with reduction in cardiovascular mortality were observed for ARBs (RR = 0.79; P = 0.005) and BBs (RR = 0.87, P = 0.004) in analyses of patient-level prescriptions. These associations in the facility-level model followed the same direction. CONCLUSIONS: DOPPS data show large variations across countries in AHA prescription for haemodialysis patients. The data suggest an association between ARB use and reduction in all-cause mortality, as well as with the use of BBs and reduction in cardiovascular mortality among haemodialysis patients.

Rosiglitazone is associated with mortality in chronic hemodialysis patients.

Recent studies have associated rosiglitazone, a thiazolidinedione drug, with adverse cardiovascular outcomes in the general population with diabetes. Using data from the Dialysis Outcomes and Practice Patterns Study in the United States, we examined cardiovascular hospitalization and mortality associated with prescription of rosiglitazone, compared with other oral hypoglycemic agents, among 2393 long-term hemodialysis patients who were followed for a median of 1.1 yr. We assessed mortality risk using Cox models in patient-level and dialysis facility-level analyses that used the facility proportion of patients on rosiglitazone as the predictor (instrumental variable approach) and adjusted the models for demographics, comorbid conditions, laboratory values, and achieved dialysis dosage. Compared with patients prescribed other oral hypoglycemic agents, patients prescribed rosiglitazone had significantly higher all-cause (hazard ratio [HR] 1.38; 95% confidence interval [CI] 1.05 to 1.82) and cardiovascular (HR 1.59; 95% CI 1.14 to 2.22) mortality, and their adjusted HR for hospitalization with myocardial infarction was 3.5-fold higher (P = 0.02). We did not observe similar associations in a secondary analysis evaluating pioglitazone. By the instrumental variable approach, facilities with more than the median adjusted percentage (6.2%) of patients who had diabetes and were prescribed rosiglitazone had significantly higher all-cause mortality (HR 1.36; 95% CI 1.15 to 1.62) and cardiovascular mortality (HR 1.42; 95% CI 1.07 to 1.88) than facilities with less than the median expected percentage prescribed rosiglitazone. Our practice-based findings suggest significant associations of rosiglitazone use with higher cardiovascular and all-cause mortality among hemodialysis patients with diabetes.

Chronic kidney disease prevention in Singapore.

In consideration of the epidemiologic basis for screening and surveillance, a comprehensive program for chronic kidney disease prevention was initiated in Singapore by the National Kidney Foundation Singapore (NKF Singapore) in 1997. Reasons for developing this include the rising rate of end-stage renal disease in the country, and the projected escalation because of the increase in chronic diseases that lead to end-stage renal disease (ESRD) such as diabetes mellitus and hypertension. Presented are progress and preliminary findings of this program, as well as that of the parallel initiative of Singapore's Ministry of Health. The NKF Singapore program incorporates primary, secondary and tertiary approaches to the prevention of chronic kidney disease. These include the population-based screening for early chronic kidney disease and chronic diseases that are associated with kidney disease and the implementation of disease management programs that aim to improve the multi-faceted care of patients with chronic diseases that lead to ESRD, including the development of community-based "Prevention Centers." The screening program identified risk factors for proteinuria, including the Malay race, increasing age, family history of kidney disease, and higher levels of systolic and diastolic BP even within the normal ranges. Longitudinal follow-up of both prevention programs are critical to provide evidence for the efficacy of such screening and intervention programs in improving chronic kidney disease outcomes, while reducing the cost of care.

Differences in intermediate outcomes for Asian and non-Asian adult hemodialysis patients in the United States.

BACKGROUND: There is a paucity of information regarding the clinical experience of Asian hemodialysis patients. This paper describes intermediate outcomes for adult Asian hemodialysis patients compared to Caucasians and African Americans. METHODS: Dialysis facility staff abstracted clinical information on a national random sample of adult hemodialysis patients from October through December 2000. Associations of race with intermediate outcomes were tested by bivariate analyses and multivariable logistic regression modeling. RESULTS: A total of 429 patients were identified as Asian, 4403 as Caucasians, and 3103 as African Americans. Asian and Caucasian patients were older than African Americans [mean 63.2 (+/-15.6), 63.9 (+/-15.2), and 57.7 (+/-14.7) years, P < 0.001], and had fewer years on dialysis [mean 3.5 (+/-3.8), 3.1 (+/-3.8), and 4.1 (+/-4.1) years, P < 0.001]. Ninety three percent of Asians, 87% of Caucasians, and 84% of African Americans had a mean Kt/V > or =1.2 (P < 0.001). In addition, 36% of Asians, 32% of Caucasians, and 26% of African Americans had an arteriovenous (AV) fistula as their vascular access (P < 0.001). Hemoglobin profiles were only slightly different among the three racial groups. More Asians and African Americans had a mean serum albumin > or =4.0/3.7 g/dL compared to Caucasians (33% and 31% compared to 27%, respectively, P < 0.001). In the final multivariable logistic regression model, Asians were twice as likely to have a mean Kt/V > or =1.2 compared to Caucasians (the referent group) [odds ratio (OR) (95% CI) 2.10 (1.33, 3.32), P < 0.01]. They experienced similar intermediate outcomes for vascular access, anemia management, and serum albumin compared to the majority racial group. CONCLUSION: These findings indicate that adult hemodialysis Asian patients experience similar or better intermediate outcomes compared to the majority racial group. Further study is needed to determine if these results are associated with improved survival and less morbidity in this minority group.

Screening for chronic kidney disease: unresolved issues.

End-stage renal disease is epidemic in the United States. As a measure to control this epidemic, it has been recommended that individuals who are at risk for CKD be tested for undetected kidney disease during routine health care encounters. There are generally accepted criteria against which screening recommendations for CKD control and prevention programs should be judged. If detection strategies are to be adopted for the screening of kidney disease, then CKD must represent a significant public health problem, be characterized by a clear natural history with a detectable asymptomatic period, outcomes should be improved by early treatment, and acceptable screening tests should be available. Health systems must provide adequate and appropriate follow-up medical care for individuals with newly detected CKD. Finally, the cost-effectiveness of screening needs to be demonstrated and the effectiveness of screening as a means of achieving reductions in CKD should be proven in randomized trials.
