Exclusive breastfeeding and length of hospital stay in premature infants at a Brazilian reference center for kangaroo mother care

Abstract Objective: To evaluate exclusive breastfeeding at discharge and hospital length-of-stay in pre-term infants undergoing or not the Kangaroo-Mother Care Method (KMC). Methods: A retrospective cohort study was conducted including preterm infants < 1800 g admitted to the neonatal unit of a KMC reference center. The infants were grouped into the KMC group and the non-KMC group. Multiple logistic and Poisson regressions were performed to evaluate the association between the KMC and two outcomes, exclusive breastfeeding at discharge, and hospital length-of-stay, adjusted for potential confounders. Results: 115 mother-infant dyads were included, 78 in the KMC group and 37 in the non-KMC group. In the bivariate analysis, the KMC group had a lower prevalence of maternal adverse conditions (6% vs. 32%, p < 0.001), a higher number of prenatal visits (median 6 vs. 3.5, p < 0.001), higher gestational ages (median 32 vs. 31 weeks, p < 0.05), higher birth weights (median 1530 vs. 1365 g, p < 0.01), a lower prevalence of necrotizing enterocolitis (3.8% vs. 16.2%, p < 0.05), parenteral nutrition (50% vs. 73%, p < 0.05), and deep vascular access (49.7% vs. 78.4%, p < 0.01), a higher prevalence of exclusive breastfeeding (65% vs. 8%, p < 0.001) and a shorter length of hospital stay (median 28 vs. 42 days, p < 0.001). In the multiple regression analysis, the KMC group was 23 times more likely to be exclusively breastfed at discharge (OR = 23.1; 95% CI = 4,85-109,93) and had a 19% reduction in the hospital length-of-stay (IDR = 0.81; 95% CI = 0.76-0.86) compared to the non-KMC group. Conclusions: The KMC is associated with better short-term neonatal outcomes and should be encouraged in all Brazilian maternity hospitals.

Extended half-life recombinant factor VIII treatment of hemophilia A in Brazil: an expert consensus statement

Introduction Treatment of hemophilia A in Brazil is offered to all patients at no cost. However, several unmet medical needs exist. Method In this study, we applied the Delphi method to discuss with seven hemophilia A specialists the challenges that patients and the health system face regarding hemophilia A treatment and opportunities for improvement. Results A consensus was obtained regarding the number of weekly infusions and patient adherence to treatment. The bleeding profile, unfavourable pharmacokinetics (PKs), low adherence and high daily activity were patient profiles that would benefit from using the extended half-life (EHL) recombinant factor VIII (rFVIII). The advantages of treatment with the EHL rFVIII were the lower number of infusions per week, which could increase patient adherence and decrease the risk of bleeds, due to a more constant plasma level, a lower value. Additionally, the EHL rFVIII could improve quality of life, especially in patients with high daily activity, such as adolescents and young adults. The panelists mentioned that EHL rFVIII, if available, could be offered first to the priority group (adolescents between 12 and 19 years old), followed by adults (20 to 64 years old) and elderly people (over 65 years old). Conclusion In summary, the EHL rFVIII offers the optimal prophylaxis by decreasing the dose frequency, increasing the treatment adherence and improving the QoL, without compromising safety and efficacy.

Exploring Modern Mechanism of Treating Diabetic Retinopathy and Coronary Heart Disease from Perspective of Blood Stasis Under Viewpoint of Treating Different Diseases with the Same Method / 中国实验方剂学杂志

Diabetic retinopathy（DR） and coronary heart disease（CHD） are both major chronic vascular complications that seriously jeopardize the health of the population and often occur together in clinical practice， it is of great clinical value to actively explore the association between the two in the process of disease development and methods of prevention and treatment of modern medicine and traditional Chinese medicine（TCM）. According to TCM， the heart and eyes physiologically communicate with each other by taking Qi， blood and veins as bridges， blood stasis obstructing collaterals is the common TCM etiology of DR and CHD， whose mechanism involves inflammation， oxidative stress and endothelial dysfunction. Promoting blood circulation and removing blood stasis plays an important role in the same treatment for different diseases and prevention and treatment of comorbidities， possibly by inhibiting the expression of interleukin-1β（IL-1β）， endothelin-1（ET-1） and hypoxia inducible factor-1α/vascular endothelial growth factor（HIF-1α/VEGF）， regulating phosphatidylinositol 3-kinases/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） pathway， initiating adenosine monophosphate（AMP）-activated protein kinase/silent information regulator 1（AMPK/SIRT1） and nuclear transcription factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathways， inhibiting Hippo/Yes-associated protein（Hippo/YAP） signaling pathway， inhibiting mitochondrial permeability transition pore and anti-platelet agglutination for treating DR and CHD， which provides a multi-component， multi-pathway and multi-target selection strategies and ideas for the prevention and treatment of DR and CHD by TCM from a biological perspective. Based on this， subsequent studies should focus on constructing clinically relevant comorbidity models， conducting multicenter prospective studies， and fully utilizing artificial intelligence technology to gain a deeper understanding of the relationship between the two diseases， so as to elucidate the mechanism of promoting blood circulation and removing blood stasis in preventing and treating panvascular diseases.

Objective To observe the clinical efficacy of withdrawal therapy based on regulating nutritive qi and defensive qi(shortened to Tiaohe Yingwei method)in treating sedative-hypnotic dependent insomnia of disharmony between nutritive qi and defensive qi type.Methods Ninety patients with sedative-hypnotic dependent insomnia of disharmony between nutritive qi and defensive qi type were randomly divided into the treatment group and the control group,with 45 patients in each group.The control group was given oral use of Estazolam by 25%of weekly dose-reduction,while the treatment group was treated with Chinese medicinal decoction of Tiaohe Yingwei Zhumian Prescription based on Tiaohe Yingwei method together with Estazolam.The treatment course for the two groups lasted for 4 weeks.The changes of Pittsburgh Sleep Quality Index(PSQI)scores,total TCM syndrome scores,and Drug-withdrawal Syndrome Scale(DWSS)scores in the two groups were observed before and after treatment.After treatment,the efficacy for improving sleep efficiency value(IUSEV)and clinical safety in the two groups were evaluated.Results(1)During the trial,2 cases fell off in the treatment group,and 43 cases included in the statistics;3 cases fell off in the control group,and 42 cases included in the statistics.(2)After 4 weeks of treatment,the total effective rate for improving IUSEV of the treatment group was 88.37%(38/43),and that of the control group was 61.90%(26/42).The intergroup comparison by non-parametric rank-sum test showed that the efficacy for improving IUSEV in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,obvious reduction was shown in the overall PSQI scores and the scores of the items of sleep quality,time for falling asleep,sleep time,sleep efficiency,sleep disorder and daytime dysfunction in the two groups when compared with those before treatment(P＜0.05).The intergroup comparison showed that except for the items of sleep disorder and daytime dysfunction,the treatment group had stronger effect on decreasing the scores of the remaining items and the overall PSQI scores than the control group(P＜0.05).(4)After treatment,the total scores of TCM syndromes of both groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease of the total scores of TCM syndrome in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the total DWSS scores of the two groups were significantly decreased compared with those before treatment(P＜0.05),and the effect on lowering the scores in the treatment group was significantly superior to that in the control group(P＜0.05).(6)During the course of treatment,no significant adverse reactions occurred in the two groups,or no abnormal changes were found in the safety indexes such as routine test of blood,urine and stool,liver and kidney function,and electrocardiogram of the patients.Conclusion Withdrawal therapy based on Tiaohe Yingwei method exerts certain effect for the treatment of sedative-hypnotic dependent insomnia of disharmony between nutritive qi and defensive qi type.The therapy is effective on improving the quality of sleep and reducing the incidence of drug-withdrawal syndrome,and has a high safety.
