RESUMEN
BACKGROUND: Extensive evidence has suggested the cardio-protective properties of the polyphenol curcumin. The aim of this study was to investigate the effects of a highly bioavailable curcumin supplement on cardiometabolic risk factors, health-related quality of life, and depression in patients with coronary slow flow phenomenon (CSFP). METHODS: This randomized double-blind placebo-controlled clinical trial was conducted in 42 patients with CSFP (age 35-70 years, 25 ≤ body mass index < 40 kg/m2). Patients received either 80 mg/day nano-curcumin or placebo for 12 weeks. Serum levels of visfatin, high-sensitivity C-reactive protein (hs-CRP), and glycemic indices were measured before and after the intervention. The short form 36-item quality of life (SF-36) and Beck's Depression Inventory-II (BDI-II) questionnaires were assessed, as well. RESULTS: No significant improvements were observed in circulating hs-CRP and visfatin following the intervention. A significant increase was observed in pre- to post-fasting blood glucose (- 0.9 ± 12.2 vs. 7.7 ± 12.4 mg/dl, p = 0.02) and hemoglobin A1C (- 0.1 ± 0.8 vs. 0.5 ± 0.8%, p = 0.04) levels, in the placebo compared with the intervention group. Physical (8.2 ± 8.1 vs. - 1.2 ± 6.5, p < 0.001) and mental (6.8 ± 11.8 vs. - 1.1 ± 10.4, p = 0.02) component summary scores were significantly improved in the nano-curcumin than the placebo group. Additionally, the number of patients with lower degrees of depression was significantly better in the intervention than the placebo group following the supplementation (p = 0.046). CONCLUSION: Curcumin supplementation prevented deterioration of glycemic control and improved physical and psychological quality of life and depression in patients with CSFP.

BACKGROUND: COVID-19 is a pandemic caused by nCoV-2019, a new beta-coronavirus from Wuhan, China, that mainly affects the respiratory system and can be modulated by nutrition. METHODS: This review aims to summarize the current literature on the association between dietary intake and serum levels of micronutrients, malnutrition, and dietary patterns and respiratory infections, including flu, pneumonia, and acute respiratory syndrome, with a focus on COVID-19. We searched for relevant articles in various databases and selected those that met our inclusion criteria. RESULTS: Some studies suggest that dietary patterns, malnutrition, and certain nutrients such as vitamins D, E, A, iron, zinc, selenium, magnesium, omega-3 fatty acids, and fiber may have a significant role in preventing respiratory diseases, alleviating symptoms, and lowering mortality rates. However, the evidence is not consistent and conclusive, and more research is needed to clarify the mechanisms and the optimal doses of these dietary components. The impact of omega-3 and fiber on respiratory diseases has been mainly studied in children and adults, respectively, and few studies have examined the effect of dietary components on COVID-19 prevention, with a greater focus on vitamin D. CONCLUSION: This review highlights the potential of nutrition as a modifiable factor in the prevention and management of respiratory infections and suggests some directions for future research. However, it also acknowledges the limitations of the existing literature, such as the heterogeneity of the study designs, populations, interventions, and outcomes, and the difficulty of isolating the effects of single nutrients from the complex interactions of the whole diet.

BACKGROUND: Cardiovascular events and poor quality of life are frequently observed in patients with coronary slow flow phenomenon (CSFP). This trial evaluated the effect of nano-curcumin supplement containing curcuminoids, as multifunctional nutraceuticals, on angina status, and some traditional and novel cardiovascular risk factors in overweight or obese patients with CSFP. METHODS: In this double-blind, randomized, placebo-controlled clinical trial, 42 overweight or obese patients with CSFP received either 80 mg/day of nano-curcumin or placebo for 12 weeks. Seattle angina questionnaire (SAQ) as a clinical measure of angina status, circulating endocan, adropin, homocysteine, lipid profile, and the novel scores of visceral adiposity index (VAI) and waist-triglyceride index (WTI) were assessed before and after the intervention. The independent samples t-test, Mann-Whitney test, analysis of covariance, Chi-square, and Fisher's exact tests were used where appropriate. RESULTS: All domains of SAQ including physical limitation, angina stability, angina frequency-severity, treatment satisfaction, and disease perception and quality of life improved significantly in the nano-curcumin compared with the placebo group. No significant changes were observed in serum endocan, adropin, and homocysteine following the intervention. Triglycerides, triglyceride/high-density lipoprotein cholesterol ratio, WTI and VAI values improved significantly only within the nano-curcumin group. CONCLUSIONS: Supplementation with 80 mg/day nano-curcumin (containing curcuminoids) for 12 weeks significantly improved clinically important disease-specific aspects of health in patients with CSFP. Some traditional and novel cardiovascular risk factors improved significantly only compared with the baseline values, which need further investigation. TRIAL REGISTRATION: This study was approved by the Ethics Committee of Tehran University of Medical Sciences (IR.TUMS.VCR.REC.1398.794). The study protocol was registered at Iranian Registry of Clinical Trials by IRCT20131125015536N8 registration ID at 19.06.2019.
RESUMEN
BACKGROUND AND AIM: Metabolic syndrome is associated with health conditions and neurological disorders. Brain-derived neurotrophic factor (BDNF) plays a protective role on the nervous system. Decreased levels of BDNF have been shown in MetS and neurodegenerative diseases. There is promising evidence regarding the anti-inflammatory antioxidant, and neuroprotective properties of virgin coconut oil (VCO). The aim of this study was to evaluate the effects of VCO consumption on serum BDNF levels, oxidative stress status, and insulin resistance in adults with MetS. METHODS: This randomized controlled clinical trial was conducted on 48 adults with MetS aged 20-50 years. The intervention group received 30â ml of VCO daily to substitute the same amounts of oil in their usual diet. The control group continued their usual diet. Serum BDNF levels, total antioxidant capacity (TAC), malondialdehyde (MDA) as well as HOMA-IR and QUICKI index were measured after four weeks of intervention. RESULTS: VCO consumption significantly reduced serum levels of MDA (p = .01), fasting insulin (p < .01) and HOMA-IR index (p < .01) and increased serum TAC (p < .01) and QUICKI index (p = .01) compared to the control group. Serum BDNF levels increased significantly in VCO group compared to the baseline (p = .02); however, this change was not significant when compared to the control group (p = .07). CONCLUSION: VCO consumption improved oxidative stress status and insulin resistance and had a promising effect on BDNF levels in adults with MetS. Further studies are needed to understand the long-term effects of VCO consumption.

Burns are associated with gut dysbiosis. Collagen peptides and omega-3 fatty acids (FAs) are suggested to improve wound healing and the inflammatory response. These are also correlated with microbiome colonization. Therefore, the present study aimed to investigate the effect of hydrolyzed collagen alone or in combination with fish oil on specific species of the gut microbiome in patients with major burns. In this randomized double-blind clinical trial, 57 adults (aged 18-60 years) with 20-45% total body surface area burns were randomised into three groups to receive either 40 gr hydrolyzed collagen +10 ml sunflower oil, 40 g hydrolyzed collagen +10 ml fish oil or placebo, divided into two daily drinks, for two weeks. Gut bacteria were measured using the real-time quantitative polymerase chain reaction (qPCR) method. The mean concentration of Bifidobacterium was significantly reduced in the control (P = 0.002) and collagen (P = 0.005) groups compared with the baseline values, whereas no significant change was observed in the collagen omega-3 group. The Firmicutes to Bacteroidetes ratio decreased significantly in the collagen group (p = 0.002) after supplementation compared to baseline . No significant changes in concentration of Lactobacillus, Enterobacteriaceae, and F.prausnitzii were observed between or within the study groups. Two weeks of supplementation with collagen and omega-3 FAs in patients with major burns did not result in a significant difference in the concentration of bacteria measured between the study groups. However, the addition of omega-3 FAs prevented a significant reduction in gut Bifidobacterium. Future studies are suggested to investigate the potential efficacy of these nutrients in improving the gut microbiota and clinical outcomes in major burns. REGISTRATION NUMBER: IRCT20131125015536N9.

BACKGROUND: This study investigated the effects of oleoylethanolamide (OEA) supplementation on the expression levels of SIRT1, AMPK, PGC-1α, PPAR-γ, CEBP-α and CEBP-ß genes and serum neuregulin 4 (NRG4) levels in patients with non-alcoholic fatty liver diseases (NAFLD). METHODS: Sixty obese patients with NAFLD were equally allocated into either OEA or placebo group for 12 weeks. The mRNA expression levels of genes were determined using the reverse transcription polymerase chain reaction (RT-PCR) technique. Serum NRG4 level was also assessed using an enzyme-linked immunosorbent assay (ELISA) kit. RESULTS: At the endpoint, mRNA expression levels of SIRT1(p = 0.001), PGC-1α (p = 0.011) and AMPK (p = 0.019) were significantly higher in the OEA group compared to placebo group. However, no significant differences were observed in the expression levels of PPAR-γ, CEBP-α and CEBP-ß between the two groups. Serum NRG4 levels significantly increased in the OEA group compared with the placebo group after controlling for confounders (p = 0.027). In the OEA group, significant relationships were found between percent of changes in the expression levels of the SIRT1, AMPK and PGC-1α as well as serum NRG4 level with percent of changes in some anthropometric measures. Moreover, in the intervention group, percent of changes in high-density lipoprotein cholesterol was positively correlated with percent of changes in the expression levels of the SIRT1 and AMPK. While, percent of changes in triglyceride was inversely correlated with percent of changes in the expression levels of SIRT1. CONCLUSION: OEA could beneficially affect expression levels of some lipid metabolism-related genes and serum NRG4 level.

Background: Neuregulin-4 (Nrg4), a novel brown fat-enriched factor, has been reported to play a crucial role in developing metabolic disorders. The current case-control study aimed to investigate the association between serum Nrg4 and coronary artery disease (CAD). Methods: This study enrolled 43 patients with CAD and 43 subjects with normal coronary arteries diagnosed by coronary angiography. Anthropometric and biochemical parameters were measured and recorded. The serum Nrg4 level was determined using the enzyme-linked immunosorbent assay. The relationships between circulating Nrg4 and CAD and other clinical parameters were analyzed. A receiver operating characteristic analysis was applied to assess the utility of Nrg4 in identifying CAD. Results: The study population comprised 86 patients, including 64 men (74.4%), at a mean age of 57.83±6.01 years. Patients with CAD had significantly lower serum Nrg4 than the control group (P<0.001). The serum Nrg4 level was negatively correlated with anthropometric variables, including the body mass index, waist circumference, and the waist-to-hip ratio, fasting blood glucose, and the triglyceride-glucose index (P<0.05). In multivariable-adjusted regression analysis, the odds of CAD decreased by 46% per 1 SD elevation in the serum Nrg4 level (OR, 0.54; 95% CI, 0.40 to 0.73; P<0.001) after controlling for potential confounders. Nrg4 showed a significantly high area under the curve value (AUC, 0.85; 95% CI, 0.75 to 0.94) with 81.4% sensitivity and 95.3% specificity to identify CAD. Conclusion: Generally, the serum level of Nrg4 declines in patients with CAD, which might be an independent risk factor for CAD.
RESUMEN
Background: Recent changes in dietary habits have resulted in increased intake of advanced glycation end products (AGEs), which are known to have a predominant contribution to the pathogenesis and complications of coronary artery disease (CAD). AGEs are also thought to induce weight gain by affecting appetite, energy expenditure, and brown adipose tissue (BAT). Here, we investigated whether the restriction of dietary AGEs could affect appetite, body composition, anthropometric indices, and BAT-derived markers in CAD patients treated with angioplasty. Materials and Methods: Forty-two stented CAD patients were randomly allocated into two groups that received either a low-AGEs or a control diet for 12 weeks. At baseline and postintervention, fasting blood samples were analyzed for total AGEs, nesfatin-1, and BAT-derived markers (fibroblast growth factor 21 and neuregulin 4). Subjective appetite ratings and body composition were evaluated using the Visual Analog Scale (VAS) and bioelectric impedance analysis. Anthropometric indices, including fat mass index (FMI), abdominal volume index (AVI), and body adiposity index (BAI), were calculated through the relevant formula. Results: Restricting dietary AGEs for 12 weeks could cause a significant reduction in weight, FMI, AVI, and BAI (P < 0.05) compared to the comparison group. In addition, VAS data analyses indicated a significant decrease in the sense of hunger and prospective food intake (P < 0.05) in the intervention group compared to the comparison group. No significant difference was seen in the measured biochemical markers between the two groups. Conclusion: This study indicated that the low-AGEs diet could decrease appetite, weight, and anthropometric indices in stented CAD patients.
RESUMEN
BACKGROUND: Infectious disease outbreaks pose a significant threat to public health, and achieving herd immunity highlights the importance of addressing conflicts of interest (COI) in vaccine development and policy-making. This policy brief aims to present policy options that address COI regarding vaccines in infectious disease outbreaks, based on good governance for health approach. METHODS: Our study used a scoping review methodology. We conducted a systematic search, which led to identifying 43 eligible articles. A qualitative approach (i.e., content analysis) was employed for data analysis, using "ATLAS.ti 9" software. The primary results underwent a process of cleaning, categorisation, and subsequent discussion in three sessions with the research team. RESULTS: Relationships between theindustry and "government/policymakers" as well as "academic institutions/researchers" are prominent origins of COI regarding the vaccine in infectious disease outbreaks. To address this issue, we present nine policy options that target both the root cause of the problem and the adoption of good governance for health approach. CONCLUSIONS: The key principles of good governance for health, including, "Transparency", "The Rule of Law", "Effectiveness", "Efficiency", "Participation", "Consensus Orientation", "Equality", "Responsibility", "Responsiveness" and "Accountability" must be taken into account when formulating policy options to address COI regarding the vaccine in infectious disease outbreaks. The effectiveness of the policy options outlined in this policy brief should be assessed in practical contexts, as this evaluation may uncover the need for revisions.

BACKGROUND AND AIMS: Neuregulin 4 (NRG4) and irisin are adipokines that have been suggested to be associated with cardiometabolic risk factors and coronary artery disease (CAD), but the data are inconclusive. This study aimed to investigate the relationship between circulating NRG4 and irisin and cardiometabolic risk factors with CAD risk and severity. METHODS AND RESULTS: In this cross-sectional study, the presence of CAD and the severity of stenosis (gensini score) were documented based on coronary angiography in 166 adults. Circulating NRG4 and irisin, glucose homeostasis markers, hs-CRP, lipid profiles, blood pressure, and anthropometric measurements were assessed as well. Age (p = 0.005), sex (p = 0.008), SBP (p = 0.033), DBP (p = 0.04), MAP (p = 0.018), FBG (p = 0.012), insulin (p = 0.039) and HOMA-IR (p = 0.01) were significantly associated with odds of having CAD. The final logistic regression model showed that age, sex, HOMA-IR, and MAP were the most important determinants of having CAD. There were no significant associations between circulating irisin and NRG4 with odds of having CAD. The final general linear model showed that being men (ß = 17.303, 95% CI: 7.086-27.52, P = 0.001), age (Aß = 0.712, 95% CI: 0.21-1.214, P = 0.006), HOMA-IR (Aß = 2.168, 95% CI: 0.256 to 4.079, P = 0.027), and NRG4 level (ß = 1.836, 95% CI: 0.119-3.553, P = 0.036) were directly associated with higher gensini score. Participants with the three-vessel disease had a mean increase of about 5 units in circulating irisin compared to those with no clinical CAD (ß = 5.221, 95% CI: 0.454-9.987, p = 0.032). CONCLUSIONS: This study showed that the adipokines NRG4 and Irisin might be associated with the severity of coronary stenosis.

It has been suggested that vitamin C is involved in suppressing stress oxidation signaling in vitiligo disease. However, the effect of vitamin C supplementation on stress oxidative factors has not been investigated in vitiligo subjects. This study was designed to examine the effects on vitamin C supplementation on serum levels of stress oxidative factors and regimentation in vitiligo patients. Forty-four vitiligo patients will be recruited in this study. After block matching for sex and number of phototherapy sessions, they will be randomly assigned to receive 1000 mg/d vitamin C or placebo for 8 weeks. The weight, height, and waist circumference of participants will be measured. Determination of serum stress oxidative indices (CAT, SOD, GPX, MDA, TOS, TAC) will be done at study baseline and at the end of the trial. Also, the regimentation will be determined using the VASI score. This is the first randomized controlled trial that will determine the effect of vitamin C supplementation on serum levels of stress oxidative indices and regimentation in vitiligo patients. The results of this trial will provide clinical evidence on the effectiveness of vitamin C supplementation in controlling oxidative stress in vitiligo patients. Trial registration number: This study is registered in the Iranian Registry of Clinical Trials website (available at http://www.irct.ir , identifier: IRCT20230123057193N1), Registration date: 2023/04/17.

OBJECTIVE: To evaluate outcomes of patients discharged home following tracheostomy, including the timing and place of death for non-survivors. STUDY DESIGN: We retrospectively reviewed medical records of infants undergoing tracheostomy between 2006 and 2017, within the first year of life for congenital or acquired neonatal conditions. RESULTS: Of the 224 patients discharged after tracheostomy, 127 (57%) required home mechanical ventilation (MV). Overall, 40 (18%) patients died (65% were on MV); 38% of the deaths occurred at home and 63% at a subsequent hospitalization. Having tube feeding was identified as significantly associated with increased mortality on multivariate analysis. Having a tracheostomy for upper airway obstruction was the only variable significantly associated with increased risk of death at home on multivariate analysis. CONCLUSIONS: Having tube feeding was associated with increased risk of death overall and having the tracheostomy for obstructive airway conditions was associated with death occurring at home.

Pleomorphic liposarcoma (PLS) is typically found in the lower and upper extremities. PLS arising in the gastrointestinal (GI) tract is extremely rare. Here, we reported a case of a 71-year-old female with a history of rectal adenocarcinoma presenting with small bowel obstruction. Small bowel resection was performed and revealed a 7.8 cm transmural mass in the jejunum. Histology reviewed a heterogenous epithelioid malignant tumor with intracytoplasmic fatty droplets scalloping the nucleus consistent with lipoblasts in some cells and others with numerous PAS/diastase+intracytoplasmic eosinophilic globules. Scattered multinucleated giant cells were also present. Mitotic count was up to 80/10 HPFs including some bizarre mitotic figures, and Ki67 proliferation index was approximately 60%. Immunohistochemistry demonstrated that the malignant cells were negative for pancytokeratin, CD117, DOG1, SMA, desmin, MyoD1, ERG1, CD34, CD31, SOX10, Melan A, and S100. INI1 was retained. Beta-catenin showed normal membranous staining. P53 was diffusely positive suggestive of mutant phenotype. Fluorescence in situ hybridization (FISH) assay was negative for MDM2 amplification and DDIT3 rearrangement. The overall morphologic and immunohistochemical features supported a diagnosis of high-grade pleomorphic liposarcoma. Diagnosis of PLS can be challenging due to its rarity in GI tract and lack of specific biomarkers, and histomorphology with identification of lipoblasts remains the gold standard.
RESUMEN
BACKGROUND: Neonatal intensive care unit (NICU) patients are at high risk for developmental delays. As a result, many are seen in neonatal follow-up (NFU) clinics. Disparities in NFU follow-up rates by social determinants of health exist. AIMS: Determine how the number of missed visits (composed of patient-canceled visits and no-show visits) relates to risk of loss to follow-up in the NFU clinic. STUDY DESIGN: Retrospective cohort study at a regional specialty center in the United States. SUBJECTS: 262 patients born between January 1, 2014, and December 31, 2017, who were referred to the NFU clinic. OUTCOME MEASURES: Logistic binomial regression was used to model risk ratio of loss to follow-up over two years, defined as not attending a recommended follow-up visit and not informing the clinic of a reason for discontinued care. RESULTS: Of 262 infants, 220 patients (84 %) were seen for at least one visit and 143 (65 %) completed follow-up. Younger maternal age, maternal smoking during pregnancy, maternal drug use during pregnancy, and public insurance were all associated with missing more visits. For each additional missed visit, the risk of loss to follow-up was 1.73 times higher unadjusted (95 % CI: 1.33, 2.26) and 1.81 times higher (95 % CI: 1.36, 2.40) after adjusting for confounders. The risk ratio of loss to follow-up for no-show visits was three times higher than that for patient-canceled visits. CONCLUSIONS: Each missed visit was independently associated with higher risk of loss to follow-up from NFU clinic, even after adjusting for other risk factors.

Background: Insulin resistance (IR), even in its subclinical state, is a significant risk factor for the onset and progression of coronary artery disease (CAD). IR is a multifactorial condition, and dietary composition is a factor associated with its development. Elevated advanced glycation end products (AGEs) in the body, secondary to highly processed food consumption, can impair glucose metabolism. The present study investigated whether a restricted AGE diet could affect insulin sensitivity and anthropometric indices reflecting visceral adipose tissue in nondiabetic CAD patients. Methods: This trial randomly allocated 42 angioplasty-treated patients to follow either low-AGE or control diets based on the AHA/NCEP guidelines for 12 weeks. Serum levels of total AGEs, insulin, HbA1c, and fasting blood sugar, as well as anthropometric measurements, were evaluated before and after the intervention. The Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and anthropometric indices were calculated according to the proposed formula. The patients' health status was assessed using the Seattle Angina Questionnaire (SAQ) at baseline and after the intervention. Results: Our study showed a significant reduction in anthropometric indices in the low-AGE group after 12 weeks. Insulin levels and IR decreased during the low-AGE diet. No significant changes were observed in the other serum biochemical markers. All SAQ domains significantly decreased in both groups, except for Treatment Satisfaction. Conclusion: A low-AGE diet for 12 weeks had beneficial effects on HOMA-IR and insulin levels in patients with CAD. Regarding the fundamental role of AGE in IR development and body fat distribution, AGE restriction may positively affect these patients.
RESUMEN
We describe our center's experience with the back transfer of infants following tracheostomies. We conducted a retrospective cohort study of infants transferred to pediatric critical care units of our regional center with conditions originating in the neonatal period who underwent tracheostomy during the hospitalization within their first year of life between 2006 and 2017. Recovering patients are discharged home or transferred back to the referring hospitals. We evaluated patient characteristics, destination of discharge and type of pulmonary support at discharge, and mechanical ventilation (MV) or tracheotomy masks (TM). Of the 139 included patients, 72% were transferred to the neonatal intensive care unit, 21% to the pediatric cardiothoracic unit, and 7% to the pediatric intensive care unit. Their median gestational age was 35 weeks. They were admitted at a median 22 days of life and lived at a median distance of 56 miles from our center. Furthermore, 34 infants (24%) were back transferred closer to their homes (23 with MV and 11 with TM), and 84 (60%) were discharged home (53 on MV and 31 on TM). Twenty-one patients (15%) died in the hospital (before discharge or transfer). Back transferred patients on MV had a significantly shorter duration between tracheostomy and transfer compared with those discharged home from our center: MV (median = 22 vs. 103 days, p < 0.0001) and TM (median = 13 vs. 35 days, p < 0.0001). Back transfer of infants with tracheostomies closer to their homes was associated with a significantly shorter hospitalization and more efficient use of the subspecialized resources at the RC.
RESUMEN
Objective: To assess the perceived risks and impact of the COVID-19 outbreak on radiation therapists in Saudi Arabia. Methods: A questionnaire was distributed to all radiation therapists in the country. The questionnaire contained questions about demographic characteristics, the extent of the pandemic's impact on hospital resources, risk perception, work-life, leadership, and immediate supervision. The questionnaire's reliability was assessed using Cronbach's alpha; >0.7 was considered adequate. Results: Out of the 127 registered radiation therapists, 77 (60.6%) responded; 49 (63.6%) females; and 28 (36.4%) males. The mean age was 36.8 ± 12.5 years. Nine (12%) of the participants had a past experience with pandemics or epidemics. Further, 46 (59.7%) respondents correctly identified the mode of transmission of COVID-19. Approximately, 69% of the respondents perceived COVID-19 as more than a minor risk to their families and 63% to themselves. COVID-19 had an overall negative impact on work at the personal and organizational levels. However, there was a positive attitude toward organizational management during the pandemic in general; positive responses ranged from 66.2% to 82.4%. Ninety-two percent considered protective resources and 70% considered the availability of supportive staff to be adequate. Demographic characteristics were not significantly associated with the perceived risk. Conclusions: Despite the high perception of risk and negative impact on their work, radiation therapists conveyed a positive overall perception regarding resource availability, supervision, and leadership. Efforts should be made to improve their knowledge and appreciate their efforts.
RESUMEN
BACKGROUND & AIMS: This study investigated the effects of collagen hydrolysate and omega-3 fatty acids (FAs) on the rate and quality of wound healing, metabolic disorders, and adipose-derived peptides in patients with major burns. METHODS: In this randomized clinical trial, 66 patients with 20-45% deep partial or full-thickness burns were randomly assigned to three groups to receive either a beverage containing collagen (40 gr/d), collagen (40 gr/d) plus 3 gr/d omega-3 (ω-3) FAs, or placebo for four weeks. Wound healing rate, Vancouver scar scale (VSS), as well as baseline, weeks two and three serum concentrations of adiponectin, fibroblast growth factor 21 (FGF21), neuregulin 4 (NRG4), transforming growth factor (TGF)-ß1, and pre-albumin/hs-CRP ratio were assessed. RESULTS: The wound healing rate during the weeks post-burn (p = 0.006 and p = 0.01), and days of 95% (21.3 ± 6.8 and 22.9 ± 8.7 vs. 34.3 ± 14.8 days, p = 0.003 and p = 0.03) and complete (26 ± 7.7 and 27.4 ± 9.4 vs. 41.1 ± 16.6 days, p = 0.003 and p = 0.01) wound healing were significantly better with Collagen and Collagen. ω-3 compared to the placebo group. The VSS was significantly lower, indicated better scar status, in the both intervention groups compared to the placebo (p = 0.02 and p = 0.01). Wound healing outcomes were not statistically different between the Collagen and Collagen. ω-3 groups. Hs-CRP/pre-albumin ratio was significantly lower in the Collagen. ω-3 than the placebo group at week three (1.2 ± 1.9 vs. 4.8 ± 7.7 dl/l, p = 0.03). The significant decrease in serum adiponectin seen during the trial course within the placebo (10 ± 8.8 to 5.8 ± 4.9 mg/l, p = 0.03) and Collagen (11.8 ± 14 to 8.6 ± 11.7 mg/l, p = 0.03) groups was prevented in the Collagen. ω-3 group (p = 0.4). Circulating FGF21 decreased significantly within the Collagen (p = 0.005) and Collagen. ω-3 (p = 0.02) groups at the end of week three compared to the baseline. CONCLUSIONS: Adding collagen hydrolysate as part of adjunctive therapy improved wound healing rate and quality. These findings as well as the efficacy of omega-3 FAs need to be further confirmed in larger populations. This study was registered with the Iranian Registry of Clinical Trials (IRCT20090901002394N42).

OBJECTIVE: We evaluate patient characteristics, hospital course, and outcome by type discharge pulmonary support; mechanical ventilation (MV) or with tracheotomy masks (TM). STUDY DESIGN: We reviewed records of infants admitted to the neonatal intensive care unit (NICU) that underwent tracheotomy within their first year of life between 2006 and 2017. We evaluated patient characteristics, referral pattern, destination of discharge, and outcome by type of pulmonary support at discharge (MV vs. TM). RESULTS: Of the 168 patients, 63 (38%) were inborn, 91 (54%) transferred to our NICU, and 5 (3%) were readmitted after being home. Median gestational age at birth was 34 weeks. Twenty-three (14%) infants were transferred to hospitals closer to their homes (13 with MV and 10 with TM), and 125 (74%) were discharged home (75 on MV and 50 on TM). Twenty patients (12%) died in the regional center (RC). Among those discharged home from our RC, infants on MV were of lower birth weight and younger gestational age, had tracheostomies later in life, had longer duration between tracheostomy to discharge to home, and had longer total duration of hospitalization at the RC. In addition, infants in the MV group were more frequently dependent on MV at time of placement of tracheostomies, less frequently had congenital airway anomalies and more frequently having possibly acquired airway anomalies and more frequently having major congenital anomalies, more frequently treated with diuretics, inhaled medications and medications for pulmonary hypertension, and more frequently had gastrostomies for feeding compared with the TM group. CONCLUSION: Patients with tracheostomies in the NICU and discharged from RC on MV or TM vary by patient characteristic, timing of tracheostomy placement, timing of discharge from RC, type of upper airway anomalies, duration of stay in the hospital, and complexity of medical condition at discharge. KEY POINTS: · Infants on home mechanical ventilation have long hospital stay and complex conditions at discharge.. · We describe factors associated with the type of pulmonary support for infants with tracheostomies.. · Treatment strategy may influence type of discharge pulmonary support in infants with tracheostomies..
