Maternal Vitamin C and Iron Intake during Pregnancy and the Risk of Islet Autoimmunity and Type 1 Diabetes in Children: A Birth Cohort Study

Our aim was to study the associations between maternal vitamin C and iron intake during pregnancy and the offspring’s risk of developing islet autoimmunity and type 1 diabetes. The study was a part of the Finnish Type 1 Diabetes Prediction and Prevention (DIPP) prospective birth cohort including children genetically at risk of type 1 diabetes born between 1997–2004. The diets of 4879 mothers in late pregnancy were assessed with a validated food frequency questionnaire. The outcomes were islet autoimmunity and type 1 diabetes. Cox proportional hazards regression analysis adjusted for energy, family history of diabetes, human leukocyte antigen (HLA) genotype and sex was used for statistical analyses. Total intake of vitamin C or iron from food and supplements was not associated with the risk of islet autoimmunity (vitamin C: HR 0.91: 95% CI (0.80, 1.03), iron: 0.98 (0.87, 1.10)) or type 1 diabetes (vitamin C: 1.01 (0.87, 1.17), iron: 0.92 (0.78, 1.08)), neither was the use of vitamin C or iron supplements associated with the outcomes. In conclusion, no association was found between maternal vitamin C or iron intake during pregnancy and the risk of islet autoimmunity or type 1 diabetes in the offspring.

Child developmental and special education service receipt: The intersection of health and poverty

BackgroundChildren born of low birth weight (LBW) and/or premature may have developmental delays and difficulties. The vulnerability, without early intervention, would have detrimental lifelong effects.ObjectivesThis study examined 1) the relationship between LBW and prematurity and the occurrence and timing of children's receipt of developmental and special education services; and 2) whether poverty intersects with LBW and prematurity affecting service receipt.MethodsThis population-based study used cross-sectional data from the National Survey of Children's Health which consisted of approximately 52,000 participants aged 1–17 between 2017 and 2018 in the United States. We conducted logistic regression to analyze the predictive relationship of LBW/prematurity and the occurrence of receiving developmental and special education services. We then conducted ordered logistic regression to examine whether LBW and prematurity predicted the timing of receiving developmental and special education services. Further, we conducted moderating analyses to examine whether the predictive relationships above varied with poverty. The analyses listed above were weighted to reflect the population drawn.ResultsChildren born with LBW and prematurity were more likely to receive developmental and special education services and they tended to receive services earlier than those born at normal weight and term. Educational disparities were evident among children in low-income families. Children of LBW in low-income families were less likely to receive earlier services than those in affluent families.ConclusionsThis study indicates developmental and special education needs of children born LBW and/or premature. With restrained assets, low-income families may need more assistance to promote optimal development for their children.

Testicular sperm retrieval: What should we expect from the fresh and subsequent cryopreserved sperm injection?

We sought to compare ICSI outcomes of cycle using fresh versus thawed TESE spermatozoa obtained during the previous fresh TESE. All consecutive couples undergoing ICSI cycles using fresh TESE spermatozoa, followed by ICSI cycle using cryopreserved sperm remaining from the previous fresh TESE procedure were included. Ovarian stimulation (OS)/laboratory variables and cycle outcome were assessed and compared between those utilising fresh versus thawed TESE spermatozoa. Seventy-five couples were evaluated, with no in-between groups differences in OS nor embryological variables. While implantation and LBR per embryo transfer were nonsignificantly higher in the frozen as compared to the fresh TESE, there was a trend towards higher LBRs per patient in the frozen TESE group. The cumulative miscarriage rate (4% versus 14.7%, p < .022 respectively) was significantly lower and the cumulative LBR (34.7% versus 16%, p < .007 respectively) was significantly higher using frozen TESE spermatozoa. Moreover, significantly higher proportion of frozen TESE sperm samples used pentoxifylline to enhance sperm motility. In conclusion, the results of ICSI cycles using frozen TESE spermatozoa are as good, or even better than using fresh TESE spermatozoa. Further studies are required to explore the factors responsible for the improved ICSI outcome, while using frozen versus fresh TESE sperm samples.     

Factors Associated With Early Return to Driving Following Total Joint Arthroplasty

BackgroundPatients often ask when they can safely return to driving a car following total joint arthroplasty (TJA). Most prior research has relied on driving simulators. Our study sought to learn more about real-world patient experiences in returning to driving after total knee arthroplasty (TKA) or total hip arthroplasty (THA).MethodsOur institutional total joint registry was used to identify living patients aged 18-85 who underwent primary TKA or primary THA for a primary diagnosis of osteoarthritis between January 1, 2019 and December 31, 2019. Patients who had undergone multiple TJA operations in 2019 or had a primary mailing address outside of the United States were excluded. Ultimately 2508 eligible TJA patients received a survey by mail.ResultsA total of 1128 of 2508 eligible patients (45%) completed surveys and returned them by mail. After 121 surveys were discarded for incompletion, inconsistency, or limited preoperative driving volume, 1007 patients were included in our study. Among these patients, 99% returned to driving postoperatively, with 23% returning within 2 weeks, and 88% returning within 6 weeks. Factors associated with the odds of a patient returning to driving within 2 weeks included laterality, gender, postoperative confidence, postoperative comfort, and surgeon advice. Ten patients (1%) have been involved in a car accident postoperatively.ConclusionAlmost all patients returned to driving postoperatively without being involved in a car accident. Gender, laterality, patient confidence, and comfort as well as surgeon advice were significantly associated with the odds of a patient returning to driving within 2 weeks postoperatively.     

Human liver stem cell-derived extracellular vesicles reduce injury in a model of normothermic machine perfusion of rat livers previously exposed to a prolonged warm ischemia

Livers from donors after circulatory death (DCD) are a promising option to increase the donor pool, but their use is associated with higher complication rate and inferior graft survival. Normothermic machine perfusion (NMP) keeps the graft at 37°C, providing nutrients and oxygen supply. Human liver stem cell-derived extracellular vesicles (HLSC-EVs) are able to reduce liver injury and promote regeneration. We investigated the efficacy of a reconditioning strategy with HLSC-EVs in an experimental model of NMP. Following total hepatectomy, rat livers were divided into 4 groups: (i) healthy livers, (ii) warm ischemic livers (60 min of warm ischemia), (iii) warm ischemic livers treated with 5 × 10⁸ HLSC-EVs/g-liver, and (iv) warm ischemic livers treated with a 25 × 10⁸ HLSC-EVs/g-liver. NMP lasted 6 h and HLSC-EVs (Unicyte AG, Germany) were administered within the first 15 min. Compared to controls, HLSC-EV treatment significantly reduced transaminases release. Moreover, HLSC-EVs enhanced liver metabolism by promoting phosphate utilization and pH self-regulation. As compared to controls, the higher dose of HLSC-EV was associated with significantly higher bile production and lower intrahepatic resistance. Histologically, this group showed reduced necrosis and enhanced proliferation. In conclusion, HLSC-EV treatment during NMP was feasible and effective in reducing injury in a DCD model with prolonged warm ischemia.     

Rehabilitación multimodal en cirugía de urgencias: ¿utopía o realidad?

Enhanced Recovery After Surgery (ERAS) constitutes the application of a series of perioperative measures based on the evidence, in order to achieve a better recovery of the patient and a decrease of the complications and the mortality. These ERAS programs initially proved their advantages in the field of colorectal surgery being progressively adopted by other surgical areas within the general surgery and other surgical specialties. The main excluding factor for the application of such programs has been the urgent clinical presentation, which has caused that despite the large volume of existing literature on ERAS in elective surgery, there are few studies that have investigated the effectiveness of these programs in surgical patients in emergencies. The aim of this article is to show ERAS measures currently available according to the existing evidence for emergency surgery.
