Filter by:The global prevalence of end-stage renal disease (ESRD) was estimated ranging 5.3 to 9.7 million patients in 2017 and is a major healthcare cost driver in both developed and developing economies. The majority of patients with ESRD, approximately 90%, received in-center maintenance hemodialysis (HD). Although HD patients are under the close supervision of a nephrologist, they are vulnerable to anemia and substantial hemoglobin (Hb) variability, which are controversially associated with poor clinical outcomes, such as all-cause mortality. The contemporary narrow target hemoglobin level recommended in the KDIGO and KDOQI guidelines, despite the ongoing debates, poses a crucial challenge in maintaining the optimal hemoglobin level in HD patients. The Big Data Center at China Medical University Hospital (CMUH) has developed a tool, Hb Scope APP, that can use the color of the HD tubing to predict real-time Hb levels by leveraging the smartphone's camera capacity and machine learning (ML) technology. The performance of the Hb Scope ML algorithm in predicting Hb > 10 g/dL can reach an accuracy of 0.93 and an AUROC of 0.99 in the testing dataset. This opens an opportunity to establish a vibrant digital ecosystem for automatic anemia management. Innovative ML tools must be appropriately regulated before these algorithms are adopted into clinical practice. Therefore, in the current validation study, we propose to do a multicenter validation trial for validating whether the Hb predicted by Hb Scope APP can achieve an area under the receiver operating curve (AUROC) of at least 0.80 in the adult HD populations from CMUH, Asia University Hospital (AUH) in Taiwan, and SEHA Kidney Care (SKC)-Central in the United Arab Emirates.
This is a randomized controlled trial, aiming to evaluate the effects of time window for umbilical cord clamping during cesarean section on the health outcomes of offspring hemoglobin，maternal blood loss，and children's growth and development. It will be conducted in Liuyang city and Huantai county of China, and the targeted sample size is 360 (180 in each site). All the eligible pregnant women will be randomly assigned to one of the four groups (three intervention groups and one control group), and their babies will be followed up to 18 months of age.
The objective of this study is to assess the effect of TA treatment on decline in Hb levels following vaginal delivery with an episiotomy, compared to a control group not receiving TA.
The aim of the study is to characterize the diet and iron status of young female elite football players and examine the relationship between iron intake, iron status, hemoglobin levels, intestinal health and sports performance. In addition, the effects of low-dose iron supplements on iron stores will be investigated and whether such supplementation affects intestinal health, microbiota composition and biomarkers for oxidative stress.
Mothers and young children in rural Ethiopia lack sufficient nutrition, and a compounding factor is presence of high levels of fluoride (> 5-10 mg/day) affecting body functions. Interventions involving chickens to provide eggs and eggshell (a source of calcium) are one solution. The overall purpose is to examine how increasing dietary calcium by using eggshell powder (ESP) reduces fluoride (F) absorption in women. It is known calcium binds F to prevent its absorption but application of this to a community based study has not been tested. The aim is to provide chickens to produce eggs for young children and to provide ESP to women (mothers). For children, an egg a day should improve growth and nutritional status. For women, the ESP provides calcium to reduce fluorosis and therefore improve function without affecting iron and zinc status. For the women, blood samples will be tested in a subsample for F, calcium, zinc and iron; urine samples will be measured for F, calcium and creatinine (to correct spot urine). Hemoglobin will be measured as an indicator of overall nutritional status in women and children. Nutritional status of young children (6-18 mo) and of their mothers prior and after the intervention (by 6 months) will be assessed. between 6 and 12 month there will be monitoring for sustainability of chilckens in the community; for continued use of egg (in children) and ESP (in women); during this time the control group will receive chickens and also undergo monitoring. The study will take place in the Rift valley of Southern Ethiopia. Identification of the knowledge, attitude and practices (KAP) of mothers on egg consumption will be done at baseline and at the end ("endline"). Caregivers will be instructed to give each child 1 egg (cooked) per day in the intervention, and one "bottle cap" of eggshell powder (1000 mg calcium) per day for themselves. Families receiving chickens will be instructed on cage construction. Throughout the study, any problems arising in keeping chickens will be recorded in order to assess the feasibility and practicality of raising chickens as way to mitigate fluorosis and improve nutritional status.
The effectiveness of micronutrient powders or MNP as a strategy for the prevention of micronutrient deficiencies has been described in the literature. However, few studies have shown the impact of the inclusion of other simultaneous actions on the different dimensions of food and nutritional security (as in the case of the project "Papas más nutritivas") that will contribute to the improvement of nutritional status, obtaining potentially greater benefits. The objective is to establish the existence of difference in hemoglobin values (and other biochemical parameters as secondary outcomes) among children aged 6 months to 5 years who receive home fortification with micronutrient powders (MNP) belonging to the project "Papas más nutritivas", and children with home fortification with MNP but not belonging to the project.
The study is a clinical trial to determine whether more efficient medical and operational outcomes can be achieved with using the new SpHb monitoring during triage in the emergency room setting. The investigators also evaluate the accuracy of the measurements of the SpHb device by Maximo versus the gold standard of central hospital laboratory value. In addition, the investigators will assess patient satisfaction with the tool.
Background: - Some treatments for cancer or other diseases can lead to infertility in women. These treatments include chemotherapy, some stem cell transplants, and pelvic radiotherapy. They are called gonadotoxic therapies. Women can now have their eggs frozen before they have these treatments. This may allow them to get pregnant later. Researchers want to learn more about this technology and processes. Objectives: - To provide egg freezing for women having gonadotoxic therapies at NIH. To learn more about the effects of these therapies. Eligibility: - Women at least 18 years old who are past puberty and before menopause. They must be scheduled to have gonadotoxic therapies. Design: - Participants will be screened with medical history and blood and hormone tests. They will also have a physical exam and transvaginal ultrasound. - Ovary stimulation: participants will have medications injected under the skin. These increase the chance of fertility. This phase will take about 8 20 days. Participants will have blood drawn and transvaginal ultrasound daily or every other day. Some participants will also have blood thinner injected daily. - Egg retrieval: participants will check in to the hospital. Eggs will be removed with a needle during a short surgery. Participants will be awake but sedated. - Participants may stay overnight in the hospital. - They will return every 1 3 days for 1 3 weeks for blood tests. - Mature eggs will be frozen after egg retrieval and immature eggs (which cannot be fertilized for clinical use) will be used for research. Participants can use their eggs in the future at outside, private fertility clinics to try to become pregnant. If the eggs are stored for more than 5 years, participants must pay for storage.
This protocol is a request from Masimo to assist in the collection of data to be used to further refine the accuracy of the monitor's algorithm.
