RESUMEN
The presence of long COVID (LC) following SARS-CoV-2 infection is a common condition that affects the quality of life of patients and represents a diagnostic challenge due to the diversity of symptoms that may coexist. We still do not have accurate information regarding the pathophysiological pathways that generate the presence of LC, and so it is important to know the inflammatory and immunothrombotic biomarker profiles and their implications in order to characterize risk subgroups and establish early therapeutic strategies. We performed the determination of inflammatory and immunothrombotic biomarkers in volunteers with previous diagnoses of SARS-CoV-2. The inflammatory biomarkers were analyzed in plasma by flow cytometry, and we analyzed the von Willebrand factor (vWF) in the plasma samples using ELISA. The clinical variables and the presence or absence of long COVID symptoms were then analyzed. IL-6, sCD40L, p-Selectin, PSGL-1, PAI-1, tPA, D-Dimer, TF, and Factor IX levels were elevated in the groups with LC, especially in the subgroup of patients with metabolic syndrome (MetS). VWF levels were found to be increased in patients with sequelae and MetS. Our results confirmed the persistence of an active immunothrombotic state, and so it is important to identify the population at risk in order to provide adequate clinical follow-up.

The objective of this research was to determine the effect of cassava (Manihot esculenta Crantz) supplementation on enteric methane (CH4) emissions, carbon footprint, and production parameters in dairy cows. Daily concentrate supply for Jersey and Jersey * Holstein breeds was evaluated in four treatments (T): T1: 100% commercial concentrate; T2: 70% concentrate + 30% cassava leaves; T3: 70% concentrate + 30% cassava roots; and T4: 70% concentrate + 15% cassava leaves + 15% cassava root chips. Measurements of CH4 emissions were performed using the polytunnel technique. Average daily dry matter intake ranged from 7.8 to 8.5 kg dry matter (DM). Cassava leaves were characterized by a high crude protein (CP) content (171 g CP/kg DM), with 5 times more neutral detergent fiber (NDF) content than cassava root (587 vs. 108 g NDF/kg DM). Average enteric CH4 emissions per animal ranged from 194 to 234 g/d (p > 0.05). The carbon footprint was reduced by replacing 30% of the concentrate with cassava leaves and/or roots. Energy-corrected milk production was 1.15 times higher in Jersey * Holstein animals than Jersey cows (47 vs. 55 kg). Therefore, supplementation with cassava leaves and/or roots is a nutritionally and environmentally sustainable strategy.

This study developed and implemented the Transition Assistance Program (TAP) for stroke caregivers. The program is composed of (1) skill development, (2) education, and (3) supportive problem solving. Sixty-one dyads (n = 122) participated: thirty-nine from Puerto Rico and twenty-two from Texas. Participants were randomly assigned to the TAP treatment or a control group. As caregiver satisfaction with the TAP increased, strain and depression decreased, and caregivers reported a very high rate of program satisfaction (9.5 out of 10). The TAP effectively reduced caregiver strain at the 3-month follow-up. When controlling for baseline differences, we found that the treatment group had lower depression (p = 0.07) than the control group at follow-up and that the TAP may have had a preventative effect on depression for caregivers who had not been depressed at discharge, although this visual trend did not reach statistical significance. Among veterans with low functioning at baseline, veterans whose caregivers had received the TAP improved in functioning more than did veterans whose caregivers had been in the control group, although this visual trend was not significant. Functioning in veterans with stroke was also significantly linked to caregiver satisfaction with the TAP. The findings from the current study warrant further evaluation of the TAP intervention.
