Postoperative Pain, an Unmet Problem in Day or Overnight Italian Surgery Patients: A Prospective Study

Background. Because of economic reasons, day surgery rates have steadily increased in many countries and the trend is to perform around 70% of all surgical procedures as day surgery. Literature shows that postoperative pain treatment remains unfulfilled in several fields such as orthopedic and general surgery patients. In Italy, the day surgery program is not yet under governmental authority and is managed regionally by local practices. Aim. To investigate the trends in pain intensity and its relation to type of surgeries and pain therapy protocols, in postoperative patients, discharged from three different Ambulatory Surgeries located in North West Italy (Piedmont region). Method. The present study enrolled 276 patients who undergone different surgical procedures in ambulatory regimen. Patients recorded postoperative pain score twice a day, compliance with prescribed drugs, and pain related reasons for contacting the hospital. Monitoring lasted for 7 days. Results. At discharge, 72% of patients were under weak opioids, 12% interrupted the treatment due to side effects, 17% of patients required extra drugs, and 15% contacted the hospital reporting pain problems. About 50% of patients experienced moderate pain during the first day after surgery. Results from our study show that most of the patients experienced avoidable pain after discharge

High Versus Low Medium Chain Triglyceride Content of Formula for Promoting Short-Term Growth of Preterm Infants

BACKGROUND: In-hospital growth of preterm infants remains a challenge in clinical practice. The high nutrient demands of preterm infants often lead to growth faltering. For preterm infants who cannot be fed maternal or donor breast milk or may require supplementation, preterm formulas with fat in the form of medium chain triglycerides (MCTs) or long chain triglycerides (LCTs) may be chosen to support nutrient utilization and to improve growth. MCTs are easily accessible to the preterm infant with an immature digestive system, and LCTs are beneficial for central nervous system development and visual function. Both have been incorporated into preterm formulas in varying amounts, but their effects on the preterm infant\u27s short-term growth remain unclear. This is an update of a review originally published in 2002, then in 2007. OBJECTIVES: To determine the effects of formula containing high as opposed to low MCTs on early growth in preterm infants fed a diet consisting primarily of formula. SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to search Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 8), in the Cochrane Library; Ovid MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily, and Ovid MEDLINE(R); MEDLINE via PubMed for the previous year; and Cumulative Index to Nursing and Allied Health Literature (CINAHL), on 16 September 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomized controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA: We included all randomized and quasi-randomized trials comparing the effects of feeding high versus low MCT formula (for a minimum of five days) on the short-term growth of preterm (\u3c 37 weeks\u27 gestation) infants. We defined high MCT formula as 30% or more by weight, and low MCT formula as less than 30% by weight. The infants must be on full enteral diets, and the allocated formula must be the predominant source of nutrition. DATA COLLECTION AND ANALYSIS: The review authors assessed each study\u27s quality and extracted data on growth parameters as well as adverse effects from included studies. All data used in analysis were continuous; therefore, mean differences with 95% confidence intervals were reported. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS: We identified 10 eligible trials (253 infants) and extracted relevant growth data from 7 of these trials (136 infants). These studies were found to provide evidence of very low to low certainty. Risk of bias was noted, as few studies described specific methods for random sequence generation, allocation concealment, or blinding. We found no evidence of differences in short-term growth parameters when high and low MCT formulas were compared. As compared to low MCT formula, preterm infants fed high MCT formula showed little to no difference in weight gain velocity (g/kg/d) during the intervention, with a typical mean difference (MD) of -0.21 g/kg/d (95% confidence interval (CI) -1.24 to 0.83; 6 studies, 118 infants; low-certainty evidence). The analysis for weight gain (g/d) did not show evidence of differences, with an MD of 0.00 g/d (95% CI -5.93 to 5.93; 1 study, 18 infants; very low-certainty evidence), finding an average weight gain of 20 ± 5.9 versus 20 ± 6.9 g/d for high and low MCT groups, respectively. We found that length gain showed no difference between low and high MCT formulas, with a typical MD of 0.10 cm/week (95% CI -0.09 to 0.29; 3 studies, 61 infants; very low-certainty evidence). Head circumference gain also showed little to no difference during the intervention period, with an MD of -0.04 cm/week (95% CI -0.17 to 0.09; 3 studies, 61 infants; low-certainty evidence). Two studies reported skinfold thickness with different measurement definitions, and evidence was insufficient to determine if there was a difference (2 studies, 32 infants; very low-certainty evidence). There are conflicting data (5 studies) as to formula tolerance, with 4 studies reporting narrative results of no observed clinical difference and 1 study reporting higher incidence of signs of gastrointestinal intolerance in high MCT formula groups. There is no evidence of effect on the incidence of necrotizing enterocolitis (NEC), based on small numbers in two trials. Review authors found no studies addressing long-term growth parameters or neurodevelopmental outcomes. AUTHORS\u27 CONCLUSIONS: We found evidence of very low to low certainty suggesting no differences among short-term growth data for infants fed low versus high MCT formulas. Due to lack of evidence and uncertainty, neither formula type could be concluded to improve short-term growth outcomes or have fewer adverse effects. Further studies are necessary because the results from included studies are imprecise due to small numbers and do not address important long-term outcomes. Additional research should aim to clarify effects on formula tolerance and on long-term growth and neurodevelopmental outcomes, and should include larger study populations to better evaluate effect on NEC incidence

Endogenous stem and precursor cells for demyelinating diseases: an alternative for transplantation?

Remyelination can be very effective in human. However, this process ultimately fails in multiple sclerosis (MS). In this paper, we discuss the possibility of stimulating endogenous oligodendrocyte precursors to participate in remyelination in experimental models (rat and primate Callithrix jacchus) of MS through thyroid hormone (TH) administration. TH is in fact known to be a key signal in brain development, oligodendrocyte development and myelin protein gene expression regulation
