The aim of the study was to compare the intestinal microbiome in very low birth weight (VLBW) infants who received different enteral iron supplementation (EIS) doses.

Longitudinal stool collection in 80 VLBW infants were conducted up to 2 months postnatally in a prospective study. The 16S rRNA regions V4 was used to calculate microbiome compositions and the Piphillin software was used for bacterial functional prediction. Linear mixed effect models and Wilcoxon rank-sum tests were performed to examine the relationships between initial EIS dosage and stool microbiome and bacterial functional potential.

There were 105 samples collected before and 237 collected after EIS started from infants with birth gestational age and weight of 28.1 ± 2.4 weeks and 1103 ± 210 g, respectively. The average postnatal age at start of EIS was 17.9 ± 6.9 days and the average initial EIS dose was 4.8 ± 1.1 mg · kg-1 · day-1. Infants who were started on ≥6 mg · kg-1 · day-1 had higher abundances of Proteus and Bifidobacterium and a lower alpha diversity than those started on lower doses (P < 0.05). Infants given higher EIS doses had higher bacterial predicted functional potentials for ferroptosis and epithelial invasion after 2 weeks post EIS.

Higher EIS dosage is linked to higher abundances of Proteus and Bifidobacterium, and a less diverse microbiome and higher predicted potential of bacterial epithelial invasion. These observational findings should be further studied in a randomized study to elucidate the optimal dosage of EIS in VLBW infants.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic led to a worldwide medical crisis, affecting mostly immunocompromised patients, such as cancer patients. Various cancer societies have issued recommendations regarding patients care, but few studies addressed the perception of cancer patients regarding this pandemic.

The aim of the study was to assess the perception of cancer patients regarding their health risks during this pandemic and the preventive measures taken.

An anonymous survey was conducted among cancer patients presenting for their treatment, during 10 consecutive working days, at the one-day clinic of Hotel-Dieu de France University hospital in Beirut. We evaluated their state of disease, comorbidities, precautions taken, and their concerns regarding the virus spread.

A total of 216 patients responded with a mean age of 60 years. The majority had a good performance status (performance status = 0-1 in 79.6%), 51.4% had metastatic disease, and chemotherapy was the main therapy used (65.7%). A total of 52.3% of patients considered themselves to be at increased risk of contracting the virus. A total of 55.1% were more worried about the coronavirus rather than their disease. The priority was for the treatment of their cancer in 47.7% of the total patients studied. Of note, only 2.8% of planned one-day clinic reservations were canceled or postponed to avoid COVID-19 exposure.

Although cancer is a disease with a high mortality rate, many patients are more concerned about the actual pandemic rather than their disease. Nevertheless, the absenteeism from their treatment sessions during the COVID-19 atmosphere was minimal.

We tested whether aerobic exercise training altered morphine analgesic responses or reduced morphine dosages necessary for adequate analgesia. check details Chronic back pain patients were randomized to an 18-session aerobic exercise intervention (n = 38) or usual activity control (n = 45). Before and after the intervention, participants underwent three laboratory sessions (double-blinded, crossover) to assess effects of saline placebo, i.v. morphine (0.09 mg/kg), and i.v. naloxone (12 mg) on low back pain and evoked heat pain responses. Differences in evoked and back pain measures between the placebo and morphine conditions indexed morphine analgesia, with pre-post intervention changes the primary outcome. Endogenous opioid (EO) analgesia was indexed by differences in evoked and low back pain measures between the naloxone and placebo conditions. A Sex X Intervention interaction on the analgesic effects of morphine on VAS back pain intensity was observed (p = .046), with a similar trend for evoked pain threshold (p = .09eceiving ≈7 mg morphine pre-intervention (p's less then .045). Greater pre-post intervention increases in EO function (from any source) were significantly associated with larger pre-post intervention decreases in morphine analgesia (p's less then .046). The overall pattern of findings suggest that regular aerobic exercise has limited direct effects on morphine responsiveness, reducing morphine analgesia in males only.
Efficacy of treatment is heavily dependent on experience and expectations. Moreover, humans can generalize from one experience to a perceptually similar but novel situation. We investigated whether and how this applies to pain relief, using ecologically valid tonic pain stimuli treated by surreptitiously lowering the applied temperature. Using different face cues, participants experienced better treatment from one physician than another. Participants were then tested on 6 additional face cues perceptually lying between both faces. Our data from 2 independent samples (N = 18 and N = 39) show a treatment experience effect, ie, for physically identical treatments, the initially superior physician was reported to deliver stronger pain relief. More importantly, the other faces on the perceptual continuum showed a graded effect of pain relief, indicating placebo generalization. Introducing a paradigm feasible to induce placebo pain relief, we show that the generic learning principle of generalization can explain carryover effects between learned and novel treatment situations.
