  The relationship between intramuscular adipose tissue at admission and recovery of activities of daily living (ADL) remains unclear. This study aimed to examine the relationship between intramuscular adipose tissue in the quadriceps at admission and recovery of ADL in older inpatients.
 
  This prospective study included 404 inpatients aged ≥65years (54.7% female). Recovery of ADL during hospital stay was assessed using the Barthel Index (BI) score at discharge, BI score change, and BI efficiency. Higher BI at discharge, BI score change, and BI efficiency indicate more improvement in ADL. Intramuscular adipose tissue and muscle mass of the quadriceps were assessed using echo intensity and muscle thickness on ultrasound images, respectively. Multiple regression analysis was performed to identify factors independently associated with BI score at discharge, BI score change, and BI efficiency. The independent variables were BI score at admission, echo intensity and muscle thickness of the quadriceps, age, sex, nu P=0.67).
 
  Our study indicates that greater intramuscular adipose tissue in the quadriceps at admission is more strongly related to worse recovery of ADL than less muscle mass in older inpatients. Greater intramuscular adipose tissue in the quadriceps in older inpatients is considered to be a predictor of worse recovery of ADL, and intervening for greater intramuscular adipose tissue may be important for improving ADL in older inpatients.

  To explore subretinal fluid (SRF) morphology in chronic central serous chorioretinopathy (cCSC) after one session of either high-density subthreshold micropulse laser (HSML) treatment or half-dose photodynamic therapy (PDT).
 
  We retrospectively obtained optical coherence tomography (OCT) scans from a subset of patients from a randomized controlled trial on treatment-naïve eyes with cCSC allocated to either HSML treatment or half-dose PDT. OCT scans were evaluated prior to treatment and 6-8weeks post-treatment, where we measured maximum SRF height and width, calculated the maximum height-to-maximum width-ratio (maxHWR) and calculated the total SRF volume.
 
  Forty-one eyes of 39 cCSC patients were included. SRF morphology ranged from flat to dome-shaped, quantified as maxHWR ranging between 0.02 and 0.12. SRF volume was median 0.373μl (range 0.010-4.425μl) and did not correlate to maxHWR (rho=-0.004, p=0.982). Half-dose PDT was superior to HSML treatment in complete SRF resolution (RR=3.28, p=0.003) and in morphological changes of SRF (Δ
  , p=0.001; Δ
  , p<0.001; Δ
  , p=0.025). SRF resolved completely in 19/22 PDT-treated eyes (86%) and 5/19 HSML-treated eyes (26%). SRF volume increased in five eyes (26%) after HSML treatment, and in none of the eyes after half-dose PDT. SRF morphology at baseline did not predict treatment outcomes.
 
  SRF morphology changed after both HSML treatment and half-dose PDT in cCSC, with SRF disappearing in most PDT-treated patients, whereas SRF volume increased in a sizeable proportion of HSML-treated patients. Baseline SRF characteristics measured in this study were unable to predict outcomes after either HSML treatment or half-dose PDT.

  Although increasing evidence suggests that visceral adipose tissue (VAT) is a major underlying cause of metabolic syndrome (MetS), few studies have measured VAT at multiple time points in diverse populations. VAT and insulin resistance were hypothesized to differ by MetS status within BMI category in the Insulin Resistance Atherosclerosis Study (IRAS) Family Study and, further, that baseline VAT and insulin resistance and increases over time are associated with incident MetS.
 
  Generalized estimating equations were used for differences in body fat distribution and insulin resistance by MetS status. Mixed effects logistic regression was used for the association of baseline and change in adiposity and insulin resistance with incident MetS across 5 years, adjusted for age, sex, race/ethnicity, and family correlation.
 
  VAT and insulin sensitivity differed significantly by MetS status and BMI category at baseline. VAT and homeostatic model assessment of insulin resistance (HOMA-IR) at baseline (VAT odds ratio [OR] = 1.16 [95% CI 1.12-2.31]; HOMA-IR OR = 1.85 [95% CI 1.32-2.58]) and increases over time (VAT OR = 1.55 [95% CI 1.22-1.98]; HOMA-IR OR = 3.23 [95% CI 2.20-4.73]) were associated with incident MetS independent of BMI category.
 
  Differing levels of VAT may be driving metabolic heterogeneity within BMI categories. Both overall and abdominal obesity (VAT) may play a role in the development of MetS. Increased VAT over time contributed additional risk.

  The prognostic importance of admission systolic blood pressure (SBP) in heart failure with preserved ejection fraction (HFpEF) is elusive.  https://www.selleckchem.com/products/ipi-145-ink1197.html  We aimed to clarify the pathophysiological differences between patients categorized with admission SBP among HFpEF patients.
 
  We studied 1008 inpatients from PURSUIT-HFpEF, a multicentre prospective observational registry. We classified patients as having elevated (>140mmHg), preserved (90-140mmHg), or low (<90mmHg) admission SBP. Most cases had elevated (n=584) or preserved (n=420) SBP; the four cases with low SBP were excluded. Univariable Cox regression testing revealed that preserved SBP patients had a higher risk of a composite of cardiac death and heart failure re-hospitalization [hazard ratio (HR) 1.48, 95% confidence interval (CI) 1.14-1.92, P=0.0035] than elevated SBP patients. In multivariable Cox regression models, while prior heart failure hospitalization (HR 1.36, 95% CI 1.01-2.84, P=0.0453), atrial fibrillation (HR 1.82, 95% CI 1.10-2.99, P=0.0209), and N-terminal pro-B-type natriuretic peptide (HR 1.
