AI Article Synopsis
- Prolonged mechanical ventilation (PMV) is linked to negative outcomes and high costs, with limited research on how protein intake affects weaning from it.
- A study of 172 patients found that those with higher daily protein intake (over 1.2 g/kg) had significantly shorter ventilator use (36.5 days vs. 114 days for lower intake).
- Factors like protein intake, serum albumin improvement, and BMI were identified as independent predictors for successful weaning from PMV, with no adverse effects on kidney function.
Article Abstract
Prolonged mechanical ventilation (PMV) is associated with poor outcomes and a high economic cost. The association between protein intake and PMV has rarely been investigated in previous studies. This study aimed to investigate the impact of protein intake on weaning from mechanical ventilation. Patients with the PMV (mechanical ventilation ≥6 h/day for ≥21 days) at our hospital between December 2020 and April 2022 were included in this study. Demographic data, nutrition records, laboratory data, weaning conditions, and survival data were retrieved from the patient’s electronic medical records. A total of 172 patients were eligible for analysis. The patients were divided into two groups: weaning success (n = 109) and weaning failure (n = 63). Patients with daily protein intake greater than 1.2 g/kg/day had significant shorter median days of ventilator use than those with less daily protein intake (36.5 vs. 114 days, respectively, p < 0.0001). Daily protein intake ≥1.065 g/kg/day (odds ratio: 4.97, p = 0.033), daily protein intake ≥1.2 g/kg/day (odds ratio: 89.07, p = 0.001), improvement of serum albumin (odds ratio: 3.68, p = 0.027), and BMI (odds ratio: 1.235, p = 0.014) were independent predictor for successful weaning. The serum creatinine level in the 4th week remained similar in patients with daily protein intake either >1.065 g/kg/day or >1.2 g/kg/day (p = 0.5219 and p = 0.7796, respectively). Higher protein intake may have benefits in weaning in patients with PMV and had no negative impact on renal function.

Chronic sleep deprivation disturbs energy balance modulated by suprachiasmatic nucleus efferents in mice.

Background: Epidemiologic researches show that short sleep duration may affect feeding behaviors resulting in higher energy intake and increased risk of obesity, but the further mechanisms that can interpret the causality remain unclear. The circadian rhythm is fine-tuned by the suprachiasmatic nucleus (SCN) as the master clock, which is essential for driving rhythms in food intake and energy metabolism through neuronal projections to the arcuate nucleus (ARC) and paraventricular nucleus (PVN).
Results: We showed that chronic SD-induced aberrant expressions of AgRP/NPY and POMC attributed to compromised JAK/STAT3 signals and reduced energy expenditure in the mice, which can be rescued with AAV-genetic overexpression of BMAL1 into SCN.
Grape pomace supplementation reduced methane emissions and improved milk quality in lactating dairy cows.

Grape pomace (GP) is a byproduct of the viticulture industry and shows promise for feeding dairy cattle as well as reducing enteric methane (CH) emissions. This study investigates the potential of using fresh GP in dairy cow feeding and its effects on CH emissions. Multiparous Holstein dairy cows (n = 24, 205 ± 39 DIM) were housed in free stall barns and provided rations consisting of alfalfa hay, wheat hay, almond hulls, cottonseed, and grain mix.

Background: Patients with head and neck cancer (HNC) undergoing radiotherapy or chemoradiotherapy often experience symptoms that affect their ability to eat. This study aimed to explore the impact of radiotherapy on body weight in HNC patients and compare the characteristics of patients receiving enteral tube feeding with those maintaining an oral diet.
Methods: In this prospective study, 52 patients with HNC were examined at diagnosis, at the start and end of radiotherapy, and six weeks after end of treatment.

Background & Aims: Abnormal expression of long noncoding RNAs is strongly linked to metabolic dysfunction-associated steatotic liver disease (MASLD). However, the precise molecular mechanisms remain unclear. This study explores the roles of noncoding RNA activated by DNA damage (NORAD)/miR-511-3p/Rho-associated protein kinase 2 (Rock2) axis and the NORAD/ROCK2 interaction in the development of MASLD.

The gut microbiota is a crucial link between diet and cardiovascular disease (CVD). Using fecal metaproteomics, a method that concurrently captures human gut and microbiome proteins, we determined the crosstalk between gut microbiome, diet, gut health, and CVD. Traditional CVD risk factors (age, BMI, sex, blood pressure) explained < 10% of the proteome variance.
