Although the correlation coefficient between body mass index (BMI) and poor lipid profile has been reported, representing a cardiovascular risk, the need to find new early detection markers is real. Waist circumference and markers of atherogenic dyslipidemia are not usually measured in medical review appointments. The present study aimed to investigate the relationship between central adiposity and cardiovascular risk. This was a cross-sectional pilot study of 57 young males (age: 35.9 ± 10.85, BMI: 32.4 ± 6.08) recruited from community settings and allocated to non-obese or obese attending to their waist circumference. Total cholesterol (TC), high-density lipoproteins (HDL-C), and low-density lipoproteins (LDL-C) cholesterol and triglycerides (TG) were measured from plasma samples. Patients with at least 100 cm of waist circumference had significantly increased TC, LDL-C, non-HDL-C, and triglycerides and lower levels of HDL-C. The three atherogenic ratios TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C were all optimal in non-obese patients. LDL-C/HDL-C and TG/HDL-C were significantly higher and over the limit when assessing for atherogenic dyslipidemia. The number of patients at risk for cardiovascular events increases 2.5 folds in obese compared to non-obese. Measurement of waist circumference could be adopted as a simpler valid alternative to BMI for health promotion, to alert those at risk of atherogenic dyslipidemia.

ObjectiveA pilot study to: (1) describe the ability of emergency physicians to provide primary consults at an Australian, major metropolitan, adult emergency department (ED) during the COVID-19 pandemic when compared with historical performance; and (2) to identify the effect of system and process factors on productivity. MethodsA retrospective cross-sectional description of shifts worked between 1 and 29 February 2020, while physicians were carrying out their usual supervision, flow and problem-solving duties, as well as undertaking additional COVID-19 preparation, was documented. Effect of supervisory load, years of Australian registration and departmental flow factors were evaluated. Descriptive statistical methods were used and regression analyses were performed. ResultsA total of 188 shifts were analysed. Productivity was 4.07 patients per 9.5-h shift (95% CI 3.56–4.58) or 0.43 patients per h, representing a 48.5% reduction from previously published data (P<0.0001). Working in a shift outside of the resuscitation area or working a day shift was associated with a reduction in individual patient load. There was a 2.2% (95% CI: 1.1–3.4, P<0.001) decrease in productivity with each year after obtaining Australian medical registration. There was a 10.6% (95% CI: 5.4–15.6, P<0.001) decrease in productivity for each junior physician supervised. Bed access had no statistically significant effect on productivity. ConclusionsEmergency physicians undertake multiple duties. Their ability to manage their own patients varies depending on multiple ED operational factors, particularly their supervisory load. COVID-19 preparations reduced their ability to see their own patients by half. What is known about the topic?An understanding of emergency physician productivity is essential in planning clinical operations. Medical productivity, however, is challenging to define, and is controversial to measure. Although baseline data exist, few studies examine the effect of patient flow and supervision requirements on the emergency physician’s ability to perform primary consults. No studies describe these metrics during COVID-19. What does this paper add?This pilot study provides a novel cross-sectional description of the effect of COVID-19 preparations on the ability of emergency physicians to provide direct patient care. It also examines the effect of selected system and process factors in a physician’s ability to complete primary consults. What are the implications for practitioners?When managing an emergency medical workforce, the contribution of emergency physicians to the number of patients requiring consults should take into account the high volume of alternative duties required. Increasing alternative duties can decrease primary provider tasks that can be completed. COVID-19 pandemic preparation has significantly reduced the ability of emergency physicians to manage their own patients.

AbstractObjectivesTo determine the independent association of central adiposity, assessed by waist circumference, with odds of psoriasis, PsA and RA prevalence after controlling for general adiposity (BMI).MethodsA cross-sectional study of UK Biobank participants aged 40–70 years was performed. Logistic regression was used to calculate the odds of psoriasis, PsA and RA occurrence compared with controls without these conditions by waist circumference, adjusting for covariates: age, sex, smoking status, socioeconomic deprivation and self-reported physical activity (Model 1), followed additionally by BMI (Model 2).ResultsA total of 502 417 participants were included; 5074 with psoriasis (1.02%), 905 with PsA (0.18%), 5532 with RA (1.11%) and 490 906 controls without these conditions. Adjusted odds ratios (ORs) (Model 1) for psoriasis, PsA and RA, per s.d. (13.5 cm) higher waist circumference were 1.20 (95% CI 1.16, 1.23), 1.30 (95% CI 1.21, 1.39) and 1.21 (95% CI 1.17, 1.24), respectively (all P < 0.001). These ORs remained significant after further adjustment for BMI (Model 2) in psoriasis [OR 1.19 (95% CI 1.12, 1.27), P < 0.001] and RA [OR 1.19 (95% CI 1.12, 1.26), P < 0.001], but not in PsA [OR 1.11 (95% CI 0.95, 1.29), P = 0.127].ConclusionCentral adiposity as measured by waist circumference is associated with greater odds of psoriasis and RA prevalence after adjustment for confounders and for BMI. Our findings add support for central adiposity as a long-term clinically relevant component of these conditions.

Background Long COVID has been a social concern. Though patient characteristics associated with developing long COVID are partially known, those associated with persisting it have not been identified. Methods We conducted a cross-sectional questionnaire survey of patients after COVID-19 recovery who visited the National Center for Global Health and Medicine between February 2020 and March 2021. Demographic and clinical data, and the presence and duration of long COVID were obtained. We identified factors associated with development and persistence of long COVID using multivariate logistic and linear regression analysis, respectively. Results We analyzed 457 of 526 responses (response rate, 86.9%). The median age was 47 years, and 378 patients (84.4%) had mild disease in acute phase. The number of patients with any symptoms after 6 and 12 months after onset or diagnosis were 120 (26.3%) and 40 (8.8%), respectively. Women were at risk for development of fatigue (OR 2.03, 95% CI 1.31-3.14), dysosmia (OR 1.91, 95% CI 1.24-2.93), dysgeusia (OR 1.56, 95% CI 1.02-2.39), and hair loss (OR 3.00, 95% CI 1.77-5.09), and were at risk for persistence of any symptoms (coefficient 38.0, 95% CI 13.3-62.8). Younger age and low body mass index were risk factors for developing dysosmia (OR 0.96, 95% CI 0.94-0.98, and OR 0.94, 95% CI 0.89-0.99, respectively) and dysgeusia (OR 0.98, 95% CI 0.96-1.00, and OR 0.93, 95% CI 0.88-0.98, respectively). Conclusion We identified risk factors for the persistence as well as development of long COVID. Many patients suffer from long-term residual symptoms, even in mild cases.

BACKGROUND: Central obesity is known as the cause of many metabolic disorders called Metabolic Syndrome. Accumulation of adipocytes in central obesity increases production of cytokines proinflammation. Free fatty acid increases in obesity that drives atherogenic dyslipidemia and insulin resistance. IDF 2005 states that waist circumference (WC) is regarded as the simple criteria of obesity. Energy imbalance lasting for a long period is a determinant factor for obesity, e.g. when energy intake is greater than energy expenditure. The brain and gastrointestinal tract work together to maintain this system. Ghrelin and Obestatin are two gut hormones that work in different ways to keep the energy balance. Ghrelin increases appetite but Obestatin decreases it. The two hormones play an important role in maintaining the dynamic equilibrium of energy balance. This study was aimed to determine correlation of Ghrelin and Obestatin with WC in central obese men.METHODS: This was a cross sectional study involving 53 central obese men. Based on IDF 2005 central obesity is most easily measured by waist circumference using the guidelines ethnic group (not country of residence) specific. We used South Asia ethnic which including Chinese, Malay and Asian Indian population as criteria for this study, that was WC >90 cm, aged 20-60 years. Subjects who had smoking habit, any infectious disease, and ACS were excluded from the study. No restriction was applied on the kind of meals the subjects were having or activities they were doing. The correlation of waist circumference with ghrelin and obestatin was assessed with a significance level of 95% (α=0,05).RESULTS: Patient's age was 40.9623±7.9080 year, waist circumferences was 102.1981±10.2696 cm, weight was 85.8679±16.5475 kg, height was 168.8066±6.3535 cm, BMI was 29.9723±2.4937 kg/m2. Concentration of Ghrelin were 0.70-13.72 ng/mL, and Obestatin 16.66-148.84 pg/mL. Pearson correlation showed that Ghrelin (r=-0.1114, p=0.4271) and Obestatin (r=-0.1781, p=0.2020) had no significant correlation with WC. But in patients WC ≥120 cm had significant negative correlation with Obestatin (r=-0.375, p=0.049).CONCLUSIONS: There was no significant correlation of Ghrelin and Obestatin with WC in obese men. However, there was a negative correlation tendency found in patients with greater WC (≥102 cm).KEYWORDS: obesity, ghrelin, obestatin, waist circumference (WC)

AbstractObjectiveObesity is a serious public health issue, the prevalence of which is increasing globally. The present study aimed to investigate trends in overweight and obesity in Irish adults between 1990 and 2011.DesignAnthropometric data from three Irish national food consumption surveys were used to calculate trends in BMI, waist circumference and waist:hip ratio.SettingThree cross-sectional food consumption surveys: the Irish National Nutrition Survey (1990), the North/South Ireland Food Consumption Survey (2001) and the National Adult Nutrition Survey (2011).SubjectsA collective sample of free-living Irish adults (n3125), aged 18–64 years.ResultsThere were significant increases in mean weight, height and BMI from 1990 to 2011. Significant increments were also reported in waist and hip circumferences and waist:hip ratio between 2001 and 2011, with concurrent increases in the proportion of individuals at risk of developing CVD, particularly females aged 18–35 years. In 2011, 23·4 % of the Irish population was classified as obese; with the mean BMI increasing by 1·1 kg/m2between 1990 and 2001 and by 0·6 kg/m2between 2001 and 2011.ConclusionsThe present paper characterises obesity levels in Irish adults from 1990 to 2011. Absolute levels of overweight and obesity have increased between these time points. Of concern is the increase in the proportion of young women classified as at risk of CVD, using waist circumference and waist:hip ratio. Effective prevention strategies are needed to avoid further increases.

AbstractObjective:To evaluate the role of central adiposity, as evaluated by the measurement of waist circumference (WC), as an independent risk factor for hypertension and type 2 diabetes mellitus in the setting of a developing country.Design:Population-based, cross-sectional study.Setting:A medium-sized town in southern Brazil.Participants:One thousand and ninety-five non-pregnant women, 20 to 69 years old, recruited by cluster random sampling between 1999 and 2000. Their mean WC was 85.3 cm (standard deviation 13.9 cm) and 23.3% (n = 255) were obese (body mass index >30 kg m−2). The prevalence of hypertension and diabetes was 25.6% (n = 280) and 6.2% (n = 68), respectively.Results:The risks of hypertension and diabetes were directly related to WC measurement. Women with WC > 80 cm had increased risk of hypertension (odds ratio (OR) = 6.2, P < 0.001). The association remained significant (OR = 1.04 per cm increase in WC, P = 0.02) after adjusting for confounders. The effect of WC on diabetes was modified by age. The effect was stronger in women younger than 40 years old (OR = 12.7, P = 0.016) than in those over 40 years old (OR = 2.8, P = 0.013). In the multivariate analysis, the odds ratio was 5.7 (P = 0.12) in those under 40 years old and 2.8 (P = 0.008) in older women.Conclusions:Waist circumference is an independent determinant for hypertension and diabetes in women in this population. The stronger association between WC and diabetes in younger women suggests that the validity of this indicator to assess abdominal adiposity is age-specific. Further studies should validate the usefulness of WC measurement in different age groups.

Background Indigenous Australians have a high prevalence of obesity and an unacceptably high rate of cardiovascular disease. Methods We conducted a cross-sectional analysis of 93 high-risk indigenous Australians to assess how strongly three anthropometric measures correlated with known cardiovascular risk factors. Results Both waist circumference and body mass index were strongly associated with important risk factors. The waist: hip ratio was less useful. Waist circumference was the only measure that significantly correlated with the urine albumin creatinine ratio (ρ = 0.14; P =0.04). Conclusion Measuring the waist circumference is a cheap, effective way of monitoring cardiovascular risk.
