Smoking, but not use of complementary and alternative medicine predicts residual functional disability in patients with inflammatory arthritis on biologic disease‐modifying anti‐rheumatic drugs: Results from the Singapore National Biologics Register

To describe inflammatory arthritis (IA) patients initiating biologic disease-modifying anti-rheumatic drugs (bDMARDs) who use complementary and alternative medicine (CAM), and determine the impact of CAM on predicting modified Health Assessment Questionnaire (mHAQ) at 6months. This was a prospective inception cohort study of patients ≥21 years old initiating a bDMARD for IA after July 2016. Data were obtained via questionnaires and abstraction from medical records. Baseline characteristics between ever-CAM and CAM non-users were compared. CAM as a predictor of mHAQ ≥1 at 6months after bDMARD initiation was analyzed using multivariate logistic regression, adjusting for other baseline characteristics. We recruited 299 patients (36.2% male, mean age 49.0 years). There were 45.8% who had rheumatoid arthritis, 54.2% had a spondyloarthropathy, median disease duration of 1.1 years and median mHAQ of 0.4. Compared to CAM non-users, ever-CAM users had a lower mean body mass index, were less likely to speak English, and more likely to smoke and drink alcohol. There was no association of CAM use with high mHAQ and no interaction with smoking. Smoking (odds ratio [OR] 938.9; 95% CI 3.20-275 884.1), baseline mHAQ (OR 252.2; 95% CI 5.34-11 899.2) and Charlson's Comorbidity Index score ≥4 (OR 237.4; 95% CI 1.22-46 184.4) independently predicted high mHAQ at 6months. CAM use was not associated with high mHAQ at 6months. Smoking was an independent predictor of residual functional disability at 6months, even after adjusting for age, comorbidity and baseline mHAQ. Greater emphasis on smoking cessation may improve long-term functional outcomes in IA patients on bDMARDs.

Comparison of survival between de novo stage IV and recurrent stage IV gastric cancer.

304 Background: The characteristics and prognosis of de novo metastatic gastric cancer and recurrent metastatic gastric cancer have not yet been elucidated. Here, we compare prognosis and characteristics of patients with de novo versus recurrent gastric cancer. Methods: This retrospective study included 301 advanced pathologically confirmed gastric cancer patients who received palliative chemotherapy between 2012 and 2022. The de novo cohort was included of patients who presented with distant metastasis at diagnosis and recurrent metastatic cohort was composed of patients with metastasis after curative gastrectomy. We analyzed prognostic association by Cox regression and compared survival time of both cohorts using the Kaplan-meire method. Results: A total of 167 de novo and 112 recurrent patients were included. There were no differences noted among the patients with de novo disease and recurrent metastatic disease with respect to age, sex, ECOG, primary cancer location and pathologic features. Patients in the recurrent group versus de novo group were longer duration of chemotherapy (1.16 ± 1.18 years versus 0.85 ± 0.84, P = 0.01) and lower mean body mass index. (20.22 ± 2.78 versus 21.93 ± 3.38, p < 0.001) The median overall survival in the de novo group was 11.6 versus s 14.4 months in the recurrent group. ( P = 0.02) In a multivariate analysis, the age of 70 years or older at the time of stage 4 diagnosis was independently associated with shorter survival. Conclusions: De novo and recurrent metastatic gastric cancer characterize distinguished subpopulations. And advanced gastric cancer with distant recurrence has significantly better survival versus those with de novo cohort. This differences between de novo and recurrent gastric cancer could facilitate discussions about patient selection of clinical trial and help with advanced personalized treatment. [Table: see text]

Sex-Specific Effects of the Genetic Variant rs10487505 Upstream of leptin in the Development of Obesity.

The SNP rs10487505 in the promotor region of the leptin gene was reported to be associated with decreased circulating leptin and increased body mass index (BMI). However, the phenotypic outcomes affected by rs10487505 in the leptin regulatory pathway have not been systematically studied. Therefore, the aim of this study was to elucidate the influence of rs10487505 on leptin mRNA expression and obesity-related parameters. We genotyped rs10487505 in DNA samples from 1665 patients with obesity and lean controls and measured leptin gene expression in paired samples of adipose tissue (AT, N = 310), as well as circulating leptin levels. We confirm the leptin-lowering effect of rs10487505 in women. In contrast to the previously reported data from population-based studies, in this mainly obese cohort, we describe a lower mean BMI in women carrying the C allele of rs10487505. However, no association of rs10487505 with AT leptin mRNA expression was found. Our data suggest that reduced circulating leptin levels are not a result of the direct silencing of leptin mRNA expression. Furthermore, leptin reduction by rs10487505 does not associate with BMI in a linear manner. Instead, the decreasing effect on BMI might be dependent on the severity of obesity.

A Comparison of Postoperative Pain and Narcotic Prescriptions in Patients Undergoing Total Hip Arthroplasty Electively or for Femoral Neck Fracture

AbstractThe opioid epidemic has forced orthopaedic surgeons to reevaluate prescribing patterns and led hospitals to develop postoperative opioid-sparing protocols for patients undergoing total hip arthroplasty (THA). The purpose of this study was to investigate patient-reported pain and narcotic requirements in patients undergoing THA for fracture (F-THA) or nonfracture diagnoses (THA-E). A retrospective analysis was performed on patients who underwent primary THA at a single academic institution between January 2013 and December 2020. Patients with postoperative opioid prescription and Visual Analog Scale (VAS) pain score data were included. Patients who underwent primary THA with a diagnosis of femoral neck fracture (THA-F) were matched 1:1 with patients without primary fracture diagnoses (THA-E) using nearest-neighbor propensity-score matching. Operative time, length of stay (LOS), discharge disposition, 90-day readmission rates, 90-day opioid prescription amounts (quantified by morphine milligram equivalents [MME]), and daily postoperative VAS pain scores (averaged over 24-hour periods) were compared. A total of 8,714 patients met inclusion criteria (THA-E: 8,362; THA-F: 352). The THA-F group was older and had a higher proportion of females and a lower mean body mass index than the THA-E group. There were 331 THA-F patients successfully matched to 331 THA-E patients. Operative time (113.6 ± 41.3 vs. 914.9 ± 32.6 minutes, p < 0.001) and LOS (2.90 ± 2.82 vs. 2.32 ± 1.44 days, p < 0.001) were longer in fracture patients. The THA-F demonstrated equivalent pain scores at 0 to 24 and 48 to 72 hours postoperatively but had slightly higher pain scores at 24 to 48 hours postoperatively (4.04 ± 1.67 vs. 3.71 ± 1.65, p = 0.028). Ninety-day opioid prescriptions were higher in the THA-E group (median [interquartile range], 150.0 [93.3–300.0] vs. 100.0 [40.0–200.0] MME, p = 0.034). In multivariate regression, a diagnosis of fracture was not associated with changes in MME administration. Patients undergoing primary THA electively and for femoral neck fractures can expect similar postoperative pain scores, though fracture patients may require less narcotics postoperatively. All patients should continue to be counseled preoperatively on the dangers and side effects of prolonged opioid use.

Associations of Neighborhood Opportunity and Social Vulnerability With Trajectories of Childhood Body Mass Index and Obesity Among US Children

Physical and social neighborhood attributes may have implications for children's growth and development patterns. The extent to which these attributes are associated with body mass index (BMI) trajectories and obesity risk from childhood to adolescence remains understudied. To examine associations of neighborhood-level measures of opportunity and social vulnerability with trajectories of BMI and obesity risk from birth to adolescence. This cohort study used data from 54 cohorts (20 677 children) participating in the Environmental Influences on Child Health Outcomes (ECHO) program from January 1, 1995, to January 1, 2022. Participant inclusion required at least 1 geocoded residential address and anthropometric measure (taken at the same time or after the address date) from birth through adolescence. Data were analyzed from February 1 to June 30, 2022. Census tract-level Child Opportunity Index (COI) and Social Vulnerability Index (SVI) linked to geocoded residential addresses at birth and in infancy (age range, 0.5-1.5 years), early childhood (age range, 2.0-4.8 years), and mid-childhood (age range, 5.0-9.8 years). BMI (calculated as weight in kilograms divided by length [if aged <2 years] or height in meters squared) and obesity (age- and sex-specific BMI ≥95th percentile). Based on nationwide distributions of the COI and SVI, Census tract rankings were grouped into 5 categories: very low (<20th percentile), low (20th percentile to <40th percentile), moderate (40th percentile to <60th percentile), high (60th percentile to <80th percentile), or very high (≥80th percentile) opportunity (COI) or vulnerability (SVI). Among 20 677 children, 10 747 (52.0%) were male; 12 463 of 20 105 (62.0%) were White, and 16 036 of 20 333 (78.9%) were non-Hispanic. (Some data for race and ethnicity were missing.) Overall, 29.9% of children in the ECHO program resided in areas with the most advantageous characteristics. For example, at birth, 26.7% of children lived in areas with very high COI, and 25.3% lived in areas with very low SVI; in mid-childhood, 30.6% lived in areas with very high COI and 28.4% lived in areas with very low SVI. Linear mixed-effects models revealed that at every life stage, children who resided in areas with higher COI (vs very low COI) had lower mean BMI trajectories and lower risk of obesity from childhood to adolescence, independent of family sociodemographic and prenatal characteristics. For example, among children with obesity at age 10 years, the risk ratio was 0.21 (95% CI, 0.12-0.34) for very high COI at birth, 0.31 (95% CI, 0.20-0.51) for high COI at birth, 0.46 (95% CI, 0.28-0.74) for moderate COI at birth, and 0.53 (95% CI, 0.32-0.86) for low COI at birth. Similar patterns of findings were observed for children who resided in areas with lower SVI (vs very high SVI). For example, among children with obesity at age 10 years, the risk ratio was 0.17 (95% CI, 0.10-0.30) for very low SVI at birth, 0.20 (95% CI, 0.11-0.35) for low SVI at birth, 0.42 (95% CI, 0.24-0.75) for moderate SVI at birth, and 0.43 (95% CI, 0.24-0.76) for high SVI at birth. For both indices, effect estimates for mean BMI difference and obesity risk were larger at an older age of outcome measurement. In addition, exposure to COI or SVI at birth was associated with the most substantial difference in subsequent mean BMI and risk of obesity compared with exposure at later life stages. In this cohort study, residing in higher-opportunity and lower-vulnerability neighborhoods in early life, especially at birth, was associated with a lower mean BMI trajectory and a lower risk of obesity from childhood to adolescence. Future research should clarify whether initiatives or policies that alter specific components of neighborhood environment would be beneficial in preventing excess weight in children.

The levels of BMI and patterns of obesity and overweight during the COVID-19 pandemic: Experience from the Iran STEPs 2021 survey.

Obesity and its increasing burden have become an urgent health problem all over the world. Benefiting from a national representative sample, the present study aimed to estimate the distribution of body mass index (BMI) levels and its association with metabolic and lifestyle risk factors in an Iranian adult population by sex, age, and geographical distribution. This study involves a national survey of noncommunicable disease risk factor surveillance (STEPs) in Iran. Through systematic random sampling, in compliance with safety considerations during the COVID-19 pandemic, of the 28,520 adults who gave voluntary consent and included in the study, 27,874 participants completed the questionnaires (step 1), 27,745 individuals were anthropometrically measured (step 2), and 18,119 individuals completed laboratory evaluation (step 3). Anthropometric measurements followed based on standard protocols and by using calibrated instruments. In 2021, the national prevalence of normal weight, obesity, and overweight/obesity in ≥18-year-old Iranian adults was estimated at 33.61% (95% CI: 32.99-34.23), 24.96% (24.39-25.53), and 63.02% (62.39-63.65), respectively. Compared to women, Iranian men had a lower mean BMI [25.54 (24.95-26.13 vs. 27.6 (27.07-28.12) kg/m2] (p < 0.001). There was also a significant difference in the national prevalence rate of overweight/obesity [women: 66% (61-71), men: 53% (46-60) (p < 0.001)]. The prevalence of obesity was significantly higher in participants suffering from metabolic and lifestyle risk factors. The study of the geographical extent of obesity and overweight shows that compared to national levels, the highest prevalence of being underweight was seen in the southeastern provinces. On the other hand, the highest prevalence of obesity belonged to the northeastern and central provinces. The highest provincial prevalence of obesity was almost 2.5-fold higher than the lowest provincial prevalence. The study reveals a significant difference between the prevalence of obesity in male and female participants and between different regions of the country. These findings will help policymakers, clinicians, and researchers to more accurately estimate the obesity/overweight problem and to implement more effective interventional programs to promote strategies of prevention and control of weight gain.

Variation in bone mineral density and fractures over 20 years among Canadians: a comparison of the Canadian Multicenter Osteoporosis Study and the Canadian Longitudinal Study on Aging

SummaryInternational variations in osteoporosis and fracture rates have been reported, with temporal trends differing between populations. We observed higher BMD and lower fracture prevalence in a recently recruited cohort compared to that of a cohort recruited 20 years ago, even after adjusting for multiple covariates.PurposeWe explored sex-specific differences in femoral neck bone mineral density (FN-BMD) and in prevalent major osteoporotic fractures (MOF) using two Canadian cohorts recruited 20 years apart.MethodsWe included men and women aged 50–85 years from the Canadian Multicentre Osteoporosis Study (CaMos, N = 6,479; 1995–1997) and the Canadian Longitudinal Study on Aging (CLSA, N = 19,534; 2012–2015). We created regression models to compare FN-BMD and fracture risk between cohorts, adjusting for important covariates. Among participants with prevalent MOF, we compared anti-osteoporosis medication use.ResultsMean (SD) age in CaMos (65.4 years [8.6]) was higher than in CLSA (63.8 years [9.1]). CaMos participants had lower mean body mass index and higher prevalence of smoking (p < 0.001). Adjusted linear regression models (estimates [95%CI]) demonstrated lower FN-BMD in CaMos women (− 0.017 g/cm2 [− 0.021; − 0.014]) and men (− 0.006 g/cm2 [− 0.011; 0.000]), while adjusted odds ratios (95%CI) for prevalent MOF were higher in CaMos women (1.99 [1.71; 2.30]) and men (2.33 [1.82; 3.00]) compared to CLSA. In women with prevalent MOF, menopausal hormone therapy use was similar in both cohorts (43.3% vs 37.9%, p = 0.076), but supplements (32.0% vs 48.3%, p < 0.001) and bisphosphonate use (5.8% vs 17.3%, p < 0.001) were lower in CaMos. The proportion of men with MOF who received bisphosphonates was below 10% in both cohorts.ConclusionHigher BMD and lower fracture prevalence were noted in the more recently recruited CLSA cohort compared to CaMos, even after adjusting for multiple covariates. We noted an increase in bisphosphonate use in the recent cohort, but it remained very low in men.

Impact of sarcopenia and phase angle on mortality of the very elderly.

Sarcopenia is a major component of geriatric syndrome and associated with poor clinical outcomes and mortality. However, diagnosing sarcopenia in the very elderly is difficult, and data on its epidemiology and devastating effects in this group are scarce. Phase angle (PA) is measured using bioimpedance spectroscopy and known to reflect cellular integrity and health. This study aimed to clarify the impact of sarcopenia and PA on mortality risk in very elderly people living in long-term care facilities. This prospective cohort study enrolled elderly residents living in nine long-term care facilities. We collected the participants' data, such as body mass index (BMI), comorbidities and laboratory data, from September to October 2017 and mortality data until October 2019. Nutritional status was evaluated using the Mini Nutritional Assessment (MNA) score, and multifrequency bioimpedance spectroscopy was used to assess body composition including PA. Appendicular skeletal muscle mass was calculated using the body composition monitor-derived equation of Taiwan's researchers. Sarcopenia was diagnosed using the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) definition (sarcopenia vs. normal group). We divided the participants into two groups according to the median PA value of 3.65° (high vs. low group) and performed multivariate regression analyses to verify the association with mortality risk according to sarcopenia diagnosis or PA group. A total of 279 elderly participants were enrolled; of them, 238 (85.3%) were diagnosed with sarcopenia according to EWGSOP2 guidelines. The median patient age was 83years, 211 (75.6%) were female and the median BMI was 20.4kg/m2 . The sarcopenia group was older than the normal group (84 vs. 81years; P=0.002), had a lower mean BMI (19.8 vs. 26.6kg/m2 , P<0.001) and had a lower MNA score (9 vs. 12 points, P<0.001). Sarcopenia was associated with a higher mortality risk after the adjustment for age, sex and diabetes mellitus (hazard ratio [HR], 3.744; 95% confidence interval [CI], 1.155-12.134; P=0.028). A low PA was associated with sarcopenia, older age, female sex, low MNA score and overhydration volume; it was also a significant predictor of mortality after the adjustment for age, sex, diabetes mellitus and MNA score (HR, 0.593; 95% CI, 0.420-0.837; P=0.003). Sarcopenia is prevalent among the very elderly patients in long-term care facilities. Sarcopenia and low PA are significantly associated with higher mortality risk.

Effectiveness and safety of rivaroxaban in patients with venous thromboembolism and active cancer: A subanalysis of the J'xactly study

BackgroundData on the effectiveness and safety of rivaroxaban for the treatment of patients with venous thromboembolism (VTE) and active cancer are limited in the Japanese real-world setting. MethodsIn this subanalysis of the J'xactly study, which was a multicenter, prospective, observational study, we evaluated the effectiveness and safety of rivaroxaban in patients with acute VTE and active cancer (n = 193) versus those without active cancer (n = 823). ResultsCompared with patients without active cancer, those with active cancer demonstrated a significantly different age distribution, with fewer aged <65 and ≥75 years; a lower proportion of women; a lower mean body mass index; and a lower proportion of physical inactivity, injury, thrombophilia, and heart failure. There was no difference in the initial dose distribution of rivaroxaban between patients with and without active cancer. The incidences of recurrence or aggravation of symptomatic VTE and major bleeding were not significantly different [VTE: 1.44 % vs. 2.80 % per patient-year, hazard ratio (HR) 0.50, 95 % confidence interval (CI) 0.18–1.39, p = 0.172; major bleeding: 4.49 % vs. 2.55 % per patient-year, HR 1.80, 95 % CI 0.82–3.95, p = 0.137]. Approximately 10 % of patients with active cancer died at 6 months, with a significantly higher cumulative all-cause mortality rate than those without active cancer (23.29 % vs. 2.03 % per patient-year, HR 11.31, 95 % CI 7.30–17.53, p < 0.001). ConclusionsIn patients with VTE and active cancer, rivaroxaban showed acceptable effectiveness, although clinically significant bleeding remains a concern.

Salivary Gene Expression of RANK, RANKL, and OPG in Type 1 Diabetes Mellitus and Periodontal Disease Patients.

The relationship between type 1 diabetes mellitus (T1DM) and periodontal disease may exhibit by the alteration of bone metabolism. However, evidence for this relationship is scarce and inconclusive. Thus, the aims of the present study were to investigate salivary receptor activator of nuclear factor kappa-β (RANK), receptor activator of nuclear factor kappa-β ligand (RANKL), osteoprotegerin (OPG) gene expression and the RANKL:OPG ratio in T1DM and non-T1DM. Secondary objective was to determine the relationships of RANK, RANKL and OPG gene expression to clinical parameters of T1DM and periodontal disease. Twenty patients with T1DM and twenty age-matched non-T1DM were recruited. Clinical periodontal parameters were measured. Total RNA was isolated from non-stimulated saliva, and the relative gene expressions of RANK, RANKL, OPG and RANKL:OPG ratio were determined by quantitative real-time polymerase chain reaction. The T1DM group had significantly higher mean periodontal parameters than the non-T1DM group, while the mean plaque scores of both groups were not significantly different. There was a trend of higher relative gene expression of RANK, RANKL, and the RANKL:OPG ratio and lower expression of OPG in T1DM group but no statistic significant different when compared to non-T1DM. In the T1DM group, RANKL:OPG correlated with the percentage of bleeding sites, whereas RANK, RANKL, and HbA1c levels correlated with pocket depth. Bone metabolisms demonstrating by decreased OPG gene expression and upregulated of RANK, RANKL, RANKL:OPG with higher pocket depth and bleeding in T1DM may play an important role in periodontal destruction in T1DM.

Comparison of 5-Year Follow-up Outcomes Between Primary and Revision Roux-en-Y Gastric Bypasses After Open Vertical Banded Gastroplasty: an Inverse Propensity Score-Weighted Analysis

IntroductionVertical banded gastroplasty (VBG) is associated with high weight regain; Roux-en-Y gastric bypass (RYGB) is used as a revision procedure in patients with VBG experiencing weight regain. This study compared the 5-year follow-up outcomes of primary (PRYGB) and revision RYGB after VBG (RRYGB).MethodsPatients who underwent PRYGB or RRYGB after VBG from 2008 to 2016 were enrolled. Data on weight regain, weight loss (WL), food tolerance (FT), early and late complications, and resolution or improvement in associated medical conditions were analyzed.ResultsPRYGB and RRYGB groups had 558 and 156 patients, respectively, after exclusion of the lost to follow-up patients. PRYGB group showed significantly lower mean body mass index (over the entire follow-up period), early complications, reintervention rates for late complications, and overall reintervention rates than that of the RRYGB group. On the other hand, FT scores, odds of late complications, and improvements (in the fifth year) in associated medical conditions were comparable between the two groups.ConclusionRRYGB in patients with VBG who regained weight showed comparable safety and resolution of associated diseases to that of PRYGB over the 5-year follow-up period. The WL in the RRYGB group was acceptable despite being less than that of the PRYGB group. FT was better after RRYGB than that of PRYGB in the first year; however, both were comparable at the fifth year follow-up. Patients with VBG undergoing RYGB should receive attentive treatment and evaluation of associated factors.Graphical abstract

Procedure Duration, Time Under Anesthesia, and Readmissions in Direct Anterior and Posterior Approach Total Hip Arthroplasty

BackgroundOperative time is related to complications in primary total hip arthroplasty (THA). This study compared operative time in direct anterior (DA) and posterior approach THA and whether differences were related to increased hospital readmissions within 90 days of discharge. MethodsProspectively documented data on 3,152 consecutively performed THAs by 16 surgeons at a large Midwestern United States academic healthcare system were retrospectively reviewed. All surgeons were beyond their learning curve. Cases characterized by factors extending operative time were excluded. A total of 1,235 analysis cases were performed with the DA approach and 1,608 with the posterior approach. DA patients had lower mean body mass index (P < .001), were more likely to be classified as American Society of Anesthesiologists Physical Status 1 or 2 (P < .001), and more likely to have surgery in an ambulatory setting (P < .001). ResultsTime under anesthesia was significantly longer for DA procedures by 19 to 27 minutes in hospital and ambulatory settings, respectively (P < .001). Increasing body mass index had a greater impact on anesthesia time for DA patients (P = .020). There were no differences in nontraumatic readmissions within 90 days of surgery based on surgical approach (P ≥ .480); however, significantly more DA patients classified as ASA-PS 3 or 4 were readmitted compared to those classified as ASA-PS 1 or 2 (P < .001), a difference not observed for posterior approach patients. ConclusionAnesthesia time is a modifiable risk factor for patient safety and an important factor in healthcare resource utilization. Consideration of ways to reduce DA operative times is encouraged.

Length of Stay and 30-Day Postoperative Complications Following Minimally Invasive Apical Prolapse Repair.

Data on the correlation between length of stay and postoperative complications following urogynecologic surgery are limited. The objective of this study was to use a nationwide database to examine the correlation between length of stay and 30-day postoperative complications following minimally invasive apical prolapse repair. This retrospective cohort study included women in the American College of Surgeons National Surgical Quality Improvement Program database from 2008 to 2018 who underwent laparoscopic/robotic sacrocolpopexy or uterosacral/sacrospinous repair and were discharged on postoperative day 0 (POD0) or 1 (POD1). The primary outcome was 30-day postoperative complication rate. Of the 28,269 women discharged home on POD0/1, 12,663 (45%) underwent laparoscopic/robotic sacrocolpopexy, and 15,606 (55%) underwent uterosacral/sacrospinous repair. Women discharged on POD0 were less likely to be White, less likely to have diabetes or hypertension, had lower mean body mass index, and were less likely to have undergone a hysterectomy ( P < 0.05 for all). Within 30 days of surgery, 7% had a postoperative complication, and 3% had a major complication. Women discharged on POD0 had a lower risk of any complication or any major complication. The most common complication, urinary tract infection, was lower in women discharged on POD0 (3% vs 4%, P < 0.01). Women discharged home on the same day had a higher risk of superficial surgical site infection after undergoing laparoscopic/robotic sacrocolpopexy (1.3% vs 0.5%, P < 0.01) and a higher risk of myocardial infarction/cardiac arrest after uterosacral/sacrospinous repair (0.2% vs 0%, P < 0.04). In women undergoing minimally invasive reconstructive apical repair, discharge on POD0 is correlated with similar or better (lower) 30-day postoperative complication rates compared with women discharged on POD1.

Patients with resolution of low-lying placenta and placenta previa remain at increased risk of postpartum hemorrhage.

To determine whether women who experience resolution of low placentation (low-lying placenta or placenta previa) are at increased risk of postpartum hemorrhage compared to those with normal placentation throughout pregnancy. This was a retrospective cohort study of women who delivered at Mount Sinai Hospital between 2015 and 2019, and who were diagnosed with low-lying placenta or placenta previa on transvaginal ultrasound at the time of the second-trimester anatomical survey, with resolution of low placentation on subsequent ultrasound examination. Women undergoing second-trimester anatomical survey who had normal placentation on transvaginal ultrasound 3 days before or after the cases were randomly identified for comparison. The primary outcome was the rate of postpartum hemorrhage. Secondary outcomes included the need for a blood transfusion, use of additional uterotonic medication, the need for additional procedures to control bleeding, and maternal admission to the intensive care unit. Outcomes were assessed using a multivariable logistic regression model. A total of 1256 women were identified for analysis, of whom 628 had resolved low placentation and 628 had normal placentation. Women with resolved low placentation, compared to those with normal placentation throughout pregnancy, had significantly higher mean age (33.0 ± 5.4 years vs 31.9 ± 5.5 years; P < 0.01) and lower mean body mass index at delivery (27.9 ± 5.5 kg/m2 vs 30.2 ± 5.7 kg/m2 ; P < 0.01), and were more likely to have undergone in-vitro fertilization, be of non-Hispanic white race, have posterior placental location (all P < 0.01) and have private/commercial health insurance (P = 0.04). Patients with resolved low placentation vs normal placentation had greater odds of postpartum hemorrhage (adjusted odds ratio (aOR), 3.5 (95% CI, 2.0-6.0); P < 0.01), use of additional uterotonic medication (aOR, 2.2 (95% CI, 1.5-3.1); P < 0.01) and increased rates of additional procedures to control bleeding (aOR, 4.0 (95% CI, 1.3-11.9); P = 0.01). Despite high rates of resolution of low-lying placenta and placenta previa by term, women with resolved low placentation remain at increased risk of postpartum hemorrhage compared to those with normal placentation throughout pregnancy. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Association of anticholinergic burden with undernutrition in older adults: A cross-sectional study.

Limited data are available concerning the contribution of drugs with anticholinergic properties (DAPs) to undernutrition among older adults. This study aimed to determine the potential association of anticholinergic burden (ACB) to nutrition status in older people. We prospectively enrolled participants aged over 65 who underwent a comprehensive geriatric assessment between January 2017 and June 2020. Nutrition status was assessed by the Mini Nutritional Assessment-Short Form (MNA-SF). The ACB was assessed using the ACB scale. A total of 615 participants were included in the analysis (mean age ± SD, 78.5 ± 6.6 years; male, 55.3%). The prevalence of undernutrition (MNA-SF score <12) was 22.6% (n = 139). Participants with undernutrition were predominantly older (P < 0.001), had lower mean body mass index scores (undernutrition, 27.3 ± 5.4 vs healthy, 29.5 ± 8.0; P = 0.007), had a lower educational level (P = 0.016), had higher cardiovascular disease morbidity (P < 0.001), and had a higher ACB (P < 0.001) when compared with those with normal nutrition status. In adjusted analysis, the odds of having undernutrition were higher among participants with an ACB score >1 (odds ratio, 1.20; 95% CI, 1.01-1.43; P = 0.044). The weighted multivariate linear regression analysis showed a significant inverse association between the total ACB score and MNA-SF score controlling for multiple confounders. ACB appears to be inversely correlated with nutrition status among older adults. Undernutrition may be considered an additional reason to consider deprescribing DAPs in this population.

Clinical and Functional Outcomes of Total Knee Arthroplasty in Sarcopenia: A Case-Control Retrospective Cohort Study.

The aim of the study was to investigate the relationship between sarcopenia and both clinical and functional outcome scores following total knee arthroplasty (TKA) performed for patients over 65 years of age. We assessed patient demographics, preoperative health status, postoperative Knee Society Clinical (KSS-C) and Function (KSS-F) subscores, and perioperative complications for 180 patients with sarcopenia and 345 comparatively healthy patients at a mean of 12.0 months after surgery. Multivariate logistic regression analysis was performed to define whether sarcopenia was an independent risk factor for lower KSS-F and KSS-C subscores and peroperative complication rates. Patients with sarcopenia had lower mean body mass index, preoperative albumin, and preoperative hemoglobin levels (p < 0.01). Compared with the healthy control group, patients with sarcopenia had lower KSS-C (83.0 vs. 88.2, p < 0.01) and KSS-F (79.2 vs. 86.1, p < 0.01) subscores and increased postoperative complication rates (14.1% vs. 4.1%, p < 0.01). Patients with sarcopenia present with generally poorer preoperative health and this appears to be associated with lower patient-reported clinical and functional outcome scores. Complication rates were higher among patients with sarcopenia who were still determined to have adequate health status to support TKA. Most complications were limited and could be managed with supportive treatment.

Nutritional Status, Nutritional Phenotypes, and Oral Nutritional Supplement Prescription Patterns Among Patients With Non-Dialysis Chronic Kidney Disease in British Columbia

Management of protein-energy wasting and undernutrition with oral nutritional supplements (ONS) has not been systematically studied in the non-dialysis chronic kidney disease (CKD-ND) population. We aimed to describe nutritional status, identify phenotypes of patients prescribed ONS, and evaluate ONS prescription patterns among CKD-ND patients in British Columbia. This observational study assessed adult CKD-ND patients who entered multidisciplinary CKD clinics during 2013-2018 in British Columbia. Descriptive statistics were used to describe baseline nutrition and inflammation parameters among patients prescribed ONS versus patients not prescribed ONS within 1year of clinic entry. Hierarchical clustering method with consensus clustering was applied to identify phenotypes of patients prescribed ONS. Multivariable logistic regression was used to assess the associations between ONS prescription and health region/dietitian full-time equivalents per 1,000 CKD patients. Of 15,859 CKD-ND patients, 9% of patients entering CKD clinics were prescribed ONS within 1year of clinic entry, and these patients demonstrated lower baseline estimated glomerular filtration rate, body mass index (BMI), serum albumin, bicarbonate, as well as greater age, serum phosphate, and neutrophil-to-lymphocyte ratio compared with those not receiving ONS. Cluster analysis revealed 5 phenotypes of ONS users: cluster 1 had the highest mean neutrophil-to-lymphocyte ratio; cluster 2 had the lowest mean albumin; cluster 3 had the lowest mean BMI; cluster 4 had the highest mean BMI; and cluster 5 had the lowest mean bicarbonate. There was regional variability in ONS prescription, and an odds ratio for ONS prescription of 1.32 (95% confidence interval 1.16-1.50) for every 1-unit increase in dietitian full-time equivalents per 1,000 patients. Over 3years of follow-up, overall ONS use among CKD-ND patients remained stable. This study demonstrates appropriate prescribing of ONS to patients with suboptimal nutritional status, although regional variation exists. Patients receiving ONS represent a heterogenous group with phenotypes reflecting several clinical and biochemical features of the protein-energy wasting syndrome. These findings will assist with updating ONS policy, planning quality improvement initiatives, and informing dietitian resource allocation.

Clinical characteristics of Japanese pustular psoriasis: A multicenter observational study.

Generalized pustular psoriasis (GPP) is a rare and severe subtype of psoriasis. Because of its rarity, GPP studies with a large sample size have been scarce. We studied the characteristics of GPP and pustular psoriasis using data from the West Japan Psoriasis Registry that had been registered until the end of December 2020. The dataset included 104 patients with pustular psoriasis and 1290 patients with other subtypes of psoriasis. Multivariate analysis revealed a significantly greater number of female patients, a significantly lower mean body mass index, and a significantly lower ratio of habitual drinkers in pustular psoriasis, compared to other subtypes of psoriasis. Of the 104 patients, 102 had GPP, including 88 von Zumbusch, 10 juvenile-onset, and four annular pustular psoriasis. Although the male:female ratio of GPP with psoriasis vulgaris (GPP+PsV) (47/20) was similar to that of psoriasis in Japan, the GPP without PsV (GPP-PsV) group highlighted a female predominance (13/22). The mean age at GPP onset was 45.3years, and the mean interval from PsV onset to GPP onset was 12.5years. Four of nine patients with GPP had an IL36RN gene mutation. Infection, medicine, and pregnancy were the precipitating factors for GPP. A family history of psoriasis was present in eight (7.8%) patients with GPP. Twenty-four patients with GPP had psoriatic arthritis. Biologics were used in 76.5% of patients with GPP, followed by etretinate (37.3%), cyclosporine (24.5%), methotrexate (13.7%), apremilast (8.8%), and granulocyte and monocyte adsorption apheresis (6.9%). Etretinate was used in 17 (51.5%) of 33 patients with GPP with less than 10-year history. Thus, etretinate remains a good treatment option for GPP even in the era of biologics. Hypertension was the most commonly identified comorbidity, followed by diabetes. We believe that the characteristics revealed in this study can further contribute to effective GPP management.

Relationship between Meeting Physical Activity Guideline Parameters and Body Mass Index (BMI) in Adults

Background: Physical activity (PA) and risk of obesity are inversely related in adult populations. However, the extent to which meeting different PA guidelines influence body mass index (BMI) is less known. The aim of this research was to examine how different PA guideline parameters affect BMI in adults. Methods: The Montana Behavioral Risk Factor Surveillance System (BRFSS, 2019) was used for this study. Four different PA guideline variables were used and included 1) 2-level aerobic PA (APA) (met APA or did not meet APA), 2) 2-level muscle strengthening activity (MSA) (met MSA or did not meet MSA), 3) 4-level PA (met both APA and MSA, met APA only, met MSA only, or met neither), and 4) 3-level APA categories (active, insufficiently active, or inactive). BMI was calculated from self-reported height and weight (kg/m2). Multiple linear regression was used to examine the effect of each PA guideline parameter on BMI while controlling for sociodemographic variables. Results: Findings showed that meeting the 2-level APA (slope (b) = -0.74 kg/m2, p < .0001) or the 2-level MSA (b = -0.75 kg/m2, p < .0001) guideline was associated with lower mean BMI. In the 4-level PA model, as compared to meeting neither guideline, meeting APA only (b = -0.58 kg/m2, p = .0119) or meeting both APA and MSA (b = -1.32 kg/m2, p < .0001) was associated with lower mean BMI. Meeting MSA only did not show significantly (p = .1748) different BMI from those meeting neither guideline. In the 3-level APA model, as compared to those categorized as inactive, those categorized as active (b = -0.91 kg/m2, p < .0001) had lower mean BMI. Those categorized as insufficiently active did not have significantly (p = .1748) different BMI from those categorized as inactive. Furthermore, the 4-level PA guidelines × sex interaction was significant (p = .030) and indicated lower mean BMI for females meeting either MSA only (b = -1.05 kg/m2, p = .0215), APA only (b = -1.14 kg/m2, p = .0014), or both APA and MSA (b = -1.84 kg/m2, p < .0001) guideline (p for trend < .0001). Whereas for males, only meeting both APA and MSA was associated with lower mean BMI (b = -0.77 kg/m2, p = .0077). Conclusion: This study found that meeting either APA or MSA guideline is associated with lower BMI in adults. However, sex-specific analyses indicate that this is true for females only and in dose-response fashion. Lower BMI in males is only associated with meeting both APA and MSA guidelines. Health promotion specialists concerned with obesity should understand the influence that each PA guideline has on relative body weight. Physical activity programming should promote both APA and MSA among adults in Montana.

Mid-term results of the Remeex® readjustable sling for female complex stress urinary incontinence and sonographic hypomobile urethra.

We aimed to evaluate the results of a readjustable sling (Remeex® system) among a selected group of women with complex stress urinary incontinence (SUI) with sonographic hypomobile urethra and assessing failure-related risk factors. Observational, longitudinal, prospective cohort study, including patients who underwent surgery with the Remeex® system. The primary outcome was a binary outcome in change of one level or more of the severity of urinary incontinence symptoms according to the intervals of the Incontinence Questionnaire-Short Form (ICIQ-UI-SF) score (mild, moderate, severe and very severe). Secondary outcomes were postsurgical complications, absolute ICIQ-UI-SF, 24-h pad weight test (24-h PT), urodynamic SUI and Patient Global Impression of Improvement (PGI-I) score to evaluate subjective success. Among 120 women included, after surgery we found a 70% subjective success rate, a 76.7% decrease of urinary incontinence severity and a mean reduction of the 24-h PT of 109.6 ± 291.4g. Women with post-surgical decreased severity of incontinence had lower mean body mass index (BMI) and 24-h PT than those without incontinence severity changes with statistically significant differences (p = 0.028 and p = 0.027, respectively). A logistic regression model demonstrated that a 1-point increase of BMI increased the risk of persistence of incontinence severity after surgery by 19% (OR = 1.19; 95% CI: 1.01-1.41; p = 0.040), and an increase of 10g in the pre-surgical 24-h PT represented a 3% rise of the aforementioned risk (OR = 1.03; 95% CI: 1.01-1.06; p = 0.034). In patients with complex SUI and sonographic hypomobile urethra, use of a readjustable sling (Remeex® system) led to improvement of SUI. Patients with a greater BMI and pre-surgical 24-h PT showed worse results after surgery.
