“…There are less researchers in literature on RI of renal artery and RAS, and these have positive effects on patient's treatment. These findings related with the findings of (Guinot et al 2013) that find RI is the main source of differentiate in normal and pathological resistance in flow.…”

Anaemia is a global health problem, whose development is influenced by several factors. Helicobacter pylori infection is among the factors associated with anaemia. Long term interruption of malaria transmission in the highland area of Kipsamoite led to an increase of haemoglobin levels in some few individuals. However, there are still reported cases of low Hb levels associated with anaemia. In studies that have been done on the role of H. pylori infections on anaemia, researchers hold varied views on whether or not H. pylori infections play a role in iron deficiency anaemia. This study investigated the association between H. pylori infections and anaemia in children aged 5-15 years in Western highland region of Kenya. The study adopted a case-control design and purposive sampling technique was used in selection of subjects. Haemoglobin levels and H. pylori occurrence were measured and entered into Microsoft excel. These data was summarized into descriptive statistics. Chisquare was used in hypotheses testing. A total of 105 participants were enrolled, 35 were cases and 70 were the controls. The mean haemoglobin level was found to be statistically significantly (p<0.00), haemoglobin of cases was lower (11.05 ± 1.726) than that of controls (13.01±1.897). The proportion of anaemic children among the cases was 77.1% (27) while the non-anaemic were 22.9% (8). The Chi-square showed positive statistical significant difference (p<0.05) between cases and controls. The study concluded that there was a great association between H. pylori infection and occurrence of anaemia in Western region of Kenya.

“…Elevated RRI is associated with AKI in orthopedic surgery and in critically ill patients in the medical ICU 90–92 . Renal resistive index has also been shown to be useful in predicting the progression of postoperative AKI 93 . While RRI is dependent upon renal vascular resistance and compliance, there are other factors that affect RRI especially in the unstable patient, and the indications for the test are evolving 94,95 .…”

Synopsis Acute kidney injury (AKI) is a common complication in the surgical patient and is associated with increases in mortality, an increased risk for chronic kidney disease (CKD) and hemodialysis after discharge, and increased cost. Better understanding of the risk factors that contribute to perioperative AKI has led to improved AKI prediction and will eventually lead to improved prevention of AKI, mitigation of injury when AKI occurs and enhanced recovery in patients who sustain AKI. The development of advanced clinical prediction scores for AKI, new imaging techniques and novel biomarkers for early detection of AKI provides new tools toward these ends.

“…However, interobserver variability for renal RI was previously reported to be between 4 to 7% in cardiac surgery patients. 8 Additionally, in a subsequent project by our group (NCT02831907), the mean difference between 38 individual measurements done, in cardiac surgery patients, by investigators with similar training, was 0.030 (60.023) (Intraclass correlation coefficient: 0.994, P < 0.001). All the RI measured at each timepoint were averaged.…”
