Association between Adherence to SSRI Treatment and Mortality among Individuals with Metabolic Syndrome Components

Introduction Depression and anxiety have been associated with type 2 diabetes mellitus and metabolic syndrome, major causes of cardiovascular morbidity and mortality. The effect of antidepressants in this association is unknown. This study aimed to examine the association between adherence to selective serotonin receptor inhibitors (SSRIs) and all-cause mortality among individuals with metabolic syndrome components (hypertension, obesity, and diabetes mellitus). Methods Data on 201 777 patients who were prescribed SSRIs during the years 2008–2011 were analyzed retrospectively. Adherence was measured using prescription purchase records. The moderating effect of SSRI and statin adherence on the association between metabolic syndrome load and mortality hazard risk (HR) during the study period were analyzed. The Cox-proportional hazard model adjusted to background variables was used to this end. Results During the study period, the maximal metabolic load was associated with mortality HR=1.89 (95% CI: 1.79–2) compared to participants without metabolic risk factors. A slight reduction in mortality HR was demonstrated among those with low and moderate SSRI adherence rates. Adherence to statins was negatively associated with the risk of mortality across all levels of adherence. A significant association (r=0.214, p<0.01) was found between adherence to statins and adherence to SSRIs, with higher rates of adherence to statins across all metabolic load categories. Discussion While a high metabolic load is associated with a higher risk of mortality, adherence to SSRIs only partially moderated the risk of mortality, in contrast to the protective effect of statins. Adherence differences to statins and SSRIs among individuals prescribed both medications merit further investigation.

Accelerometry-Workload Indices Concerning Different Levels of Participation during Congested Fixture Periods in Professional Soccer: A Pilot Study Conducted over a Full Season

The aim of this study was to analyze the variations of acute load (AL), acute: chronic workload ratio (ACWR), training monotony (TM), and training strain (TS) of accelerometry-based GPS measures in players who started in three matches (S3M), two matches (S2M), and one match (S1M) during congested weeks. Nineteen elite professional male players from a Portuguese team (age: 26.5 ± 4.3 years) were monitored daily using global positioning systems (GPSs) over a full season (45 weeks). Accelerometry-derived measures of high metabolic load distance (HMLD), high accelerations (HA), and high decelerations (HD) were collected during each training session and match. Seven congested weeks were classified throughout the season, and the participation of each player in matches played during these weeks was codified. The workload indices of AL (classified as ACWR, TM, and TS) were calculated weekly for each player. The AL of HMLD was significantly greater for S2M than S1M (difference = 42%; p = 0.002; d = 0.977) and for S3M than S1M (difference = 44%; p = 0.001; d = 1.231). Similarly, the AL of HA was significantly greater for S2M than S1M (difference = 25%; p = 0.023; d = 0.735). The TM of HD was significantly greater for S2M than S3M (difference = 25%; p = 0.002; d = 0.774). Accelerometry-based measures were dependent on congested fixtures. S2M had the greatest TS values, while S3M had the greatest TM.

The Running Performance Decrement in Elite Hurling

Since the COVID-19 restrictions, hurling games have been played in four quarters instead of two halves. This study described the decrement in running performance between quarters in elite hurling. GPS (10 Hz) were used to collect data from 48 players over 20 games during 2018–2020 season. Total distance (TD), high-speed running (HSR), high-metabolic-load distance (HMLD), sprint-distance, and number of sprints (N-sprints) between quarters were assessed. Greater TD was covered in Q1 than Q3 (Cohen’s d = 0.26). HSR and HMLD was greater in Q1 than Q2 (d = 0.45 and d = 0.55, respectively), Q3 (d = 0.34 and d = 44, respectively) and Q4 (d = 0.38 and d = 0.48, respectively). Sprint-distance and N-sprints were similar (p > 0.05) across quarters. All positions experienced a drop-off in at least one quarter (d = 0.43–1.46) in all metrics except midfielders’ TD and full-forwards’ HSR and HMLD. Sprint-distance and N-sprints were similar (p > 0.05) in each quarter for all positions. Following Q1, players were able to maintain their running performance. The current results can aid the timing of substitutions especially in positions where temporal decrements were observed.

Comparisons of Metabolic Load between Adaptive Support Ventilation and Pressure Support Ventilation in Mechanically Ventilated ICU Patients

Purpose. The aim of this study was to compare the metabolic load between adaptive support ventilation (ASV) and pressure support ventilation (PSV) modes in critically ill patients. Methods. Sequential 20 min ventilation by PSV followed by 20 min ASV in critically ill patients was assessed. ASV was set for full support, i.e., with the minute volume control set at the same level as the minute volume observed during PSV. The trial started from PSV 8 cmH2O and continued with high (PSV 12 cmH2O) to low (PSV 0) conditions or low to high conditions, in random order. The oxygen consumption (VO2), production of carbon dioxide (VCO2), and energy expenditure (EE) were measured by indirect calorimetry (IC). Results. Twenty-four patients with critical illness participated in the study. Comparing with the PSV mode, the EE in the ASV mode was lower in the level of PSV 0 cmH2O (1069 ± 73 vs. 1425 ± 76 kcal), PS 8 cmH2O (1116 ± 70 vs. 1284 ± 61 kcal), and PS 12 cmH2O (1017 ± 70 vs. 1169 ± 58 kcal) (p<0.05). The VO2, VCO2, and P0.1 in PSV were significantly higher than those in ASV (p<0.05). Conclusion. In patients with critical illness, the application of ASV set for full support was associated with a lower metabolic load and respiratory drive than in any of the studied PSV conditions.

Albumin Loss and Citrate Load in Pre-Dilution High Cut-Off-CVVHDF with Regional Citrate (18 mmol/L) and High Cut-Off CVVHD with Systemic Heparin: An in vitro Study

Background: Convective therapies with high cut-off membranes (HCO) are usually not recommended because of theoretical excessive albumin loss. The aim of this in vitro study is to demonstrate the noninferior safety of pre-dilution hemodiafiltration with HCO (HCO-CVVHDF) with isotonic citrate anticoagulation (18 mmol/L) with respect to heparin anticoagulated hemodialysis with HCO (HCO-CVVHD) in terms of albumin removal and citrate load. Method: ­Albumin removal was compared in vitro between 3 pre-­dilution-HCO-CVVHDF with citrate anticoagulation and 3 ­HCO-CVVHD with heparin anticoagulation during 30-min single-pass and 180-min recirculation phases. Results: Considering concentrations and flows in the extracorporeal circuit, the transmembrane albumin removal was 2.06 (1.51; 2.09) g and 2.09 (1.9; 2.8) g respectively for HCO-CVVHDF and HCO-CVVHD, during the single-pass phase; 2.8 (2.67; 4.59) g and 2.54 (2.35; 4.67) g, respectively, for HCO-CVVHDF and HCO-CVVHD during the recirculation phase. Based on the citrate saturation coefficients, a citrate metabolic load of 8.86 mmol/h has been calculated for HCO-CVVHDF. Conclusion: HCO-CVVHDF performed with regional anticoagulation with 18 mmol/L citrate solution does not induce higher ­albumin transmembrane removal compared to HCO-CVVHD.
