BackgroundThe growing obesity pandemic is the leading cause for increasing prevalence of nonalcoholic fatty liver disease (NAFLD) in children. Histopathological evaluation of the liver remains the gold standard for NAFLD diagnosis, but it is an invasive procedure with a low but real risk of morbidity and mortality. The current study evaluated circulating chemerin and adiponectin as possible noninvasive diagnostic markers for NAFLD in obese non-diabetic children.MethodsA prospective case-control study was conducted, which included 101 obese children with biopsy-proven NAFLD and 57 age- and sex-matched controls. The overall mean age of the children was 10.08±3.12 years. All underwent a full clinical assessment, routine laboratory investigation, and abdominal ultrasound. Homeostatic model assessment-insulin resistance was calculated and circulating chemerin and adiponectin were evaluated using ELISA.ResultsElevated serum chemerin and decreased serum adiponectin were significantly associated with an increased likelihood of exhibiting NAFLD. Receiver operator characteristic curve analysis for differentiation of NAFLD patients from those in the control group demonstrated that chemerin, at a cutoff value of 186.7 ng/mL, yielded a sensitivity and specificity of 56.44% and 87.72% respectively (P<0.001), whereas adiponectin, at a cutoff value of 2.4 µg/mL, had a sensitivity and specificity of 74.26% and 3.51% respectively (P<0.001). Furthermore, body mass index, aspartate transaminase, alanine transaminase, triglycerides, and gamma-glutamyl transferase had significant positive correlations with chemerin and significant negative correlations with adiponectin (P≤0.001).ConclusionCirculating chemerin and adiponectin could serve as simple noninvasive diagnostic markers for NAFLD in non-diabetic obese children.

Or use: https://youtu.be/f5M4-ruLFPo Purpose: Currently available markers for early detection of diabetic nephropathy (DN), the leading cause of end stage renal disease, have some limitations. There is insufficient evidence from previous studies about the role of several circulating microRNAs (miRNAs) in the early development of DN. This study aimed to describe the expression of miRNA-377, miRNA-93, miRNA-25, miRNA-216a, and miRNA-21 in a sample of type 1 diabetic children and adolescents to explore their association with DN and some indices of kidney injury. Patients and Methods: Seventy type 1 diabetic patients, with 5 years' duration of diabetes or more, were recruited from Children's Hospital, Faculty of Medicine, Cairo University. Quantitative real-time reverse-transcription PCR (qRT-PCR) was used to measure the expression of the above mentioned miRNAs in serum and to assess its association with DN, and the studied risk factors. Results: There was a significantly higher percentage of up-regulation of miRNA-377 and miRNA-93 (P=0.03, 0.02, respectively) in addition to significant down-regulation of miRNA-25 (P=0.01) in patients with DN than in patients without DN. In patients with DN, expression of miR-216a was significantly negatively correlated with creatinine (r=−0.4, P=0.04) and positively correlated with eGFR using creatinine (r=0.5, P=0.03). In the same group, expression of miR-21 was positively correlated with urinary cystatin C (r=0.6, P=0.01) and was negatively correlated with e-GFR using cystatin c (r=−0.6, P=0.01). miRNA-93 was associated with increased risk (odds ratio=15, 95% CI=12.03-24.63, P=0.01), while miRNA-25 was associated with decreased risk for albuminuria (odds ratio=0.15, 95% CI=0.08-0.55, P=0.03). Conclusion: miRNA-377, miRNA-93, miRNA-216a, and miRNA-21 may be implicated in the pathogenesis of DN, while miRNA-25 may have a reno-protective role. More studies are needed to document the value of these miRNAs as diagnostic biomarkers as well as therapeutic targets in DN.
Background: Pediatric shock has a high mortality rate because many of the early clinical signs are subtle and have poor sensitivity and specificity. Pediatric shock was categorized either: compensated with normal blood pressure, poor skin perfusion (CRT >2 s, mottled, cool peripheries, peripheral cyanosis), weak peripheral pulse, age specific tachycardia, tachypnoea, and oliguria or decompensated with hypotension (SBP < 70 þ (2Â age in years) mm Hg and decreased mental status. The perfusion index is a non-invasive method for assessing peripheral perfusion and may be a useful marker for identifying shock early in pediatric patients. Objective: This prospective cohort study (November 2019 to August 2020) evaluated whether the perfusion index, lactate, and/or lactate clearance could predict mortality among pediatric shock patients. Methods: Fifty children (68% male) with shock underwent assessments at presentation to the emergency room to evaluate their heart rate, blood pressure, capillary refill time, central venous pressure, perfusion index, cardiac index, systemic vascular resistance, central venous oxygen saturation, and lactate clearance. Results: The perfusion index range was 0.03 to 2.2 and 0.18 as the cut-off for mortality prediction providing 74% sensitivity and 78% specificity. The serum lactate concentration range was 0 to 16 mmol/L and >5.7 mmol/L as the cut-off for mortality prediction provided 70% sensitivity and 96% specificity at presentation to the emergency room. The lactate clearance range was 3% to 75% and >10% as the cut-off for survival prediction after resuscitation and at 6 h later. Conclusion: Perfusion index (PI), lactate, and lactate clearance provided comparable sensitivity and specificity for predicting outcomes among pediatric patients with shock Therefore, we suggest that the PI is an inexpensive, rapid, and non-invasive tool that can be used to predict illness severity and mortality in busy pediatric intensive care units and emergency departments. This tool may guide better patient triage and an earlier diagnosis of shock in this setting.
Background and Aim: Sepsis is a common cause of pediatric intensive care unit (ICU) admission. Sepsis-associated encephalopathy (SAE) may occur owing to brain dysfunction in those patients and may be related to impaired cerebral microcirculation. Transcranial Doppler (TCD) can be used to detect this impairment. In this study, we aimed to assess the role of TCD in prediction of SAE and mortality in patients with severe sepsis or septic shock admitted to PICU. Patients and Methods: This prospective study included 75 children admitted to PICU owing to severe sepsis or septic shock. Upon admission, all patients were subjected to careful history taking, thorough clinical examination, and standard laboratory workup. Severity of clinical illness was assessed using the Pediatric Risk of Mortality (PRISM) III score. TCD was performed on the first day of admission after the normalization of systolic blood pressure with or without vasopressors. The primary study outcome was differences in the measurement of TCD in SAE, and the secondary outcome was discharge from ICU or mortality. Results: The study comprised 45 children with SAE and 30 age- and sex-matched children without SAE. In this study, SAE patients had significantly higher pulsatility index [PI; median interquartile range (IQR): 1.15 (0.98–1.48) vs. 1.0 (0.95–1.06), p = 0.002] and resistive index [RI; median (IQR): 0.68 (0.61–0.77) vs. 0.62 (0.59–0.64), p = 0.001] than had non-SAE patients. PI and RI showed good performance as predictors of subsequent SAE development [area under the curve (AUC): 0.72 and 0.73, respectively]. Non-survivors in SAE patients had significantly higher PRISM III. Receiver operating characteristic (ROC) curve analysis showed good performance of PI and RI as predictors of mortality at the end of follow-up. Conclusions: In children with SAE, cerebrovascular resistance is high and is associated with increased mortality.
Objective We aimed to study the effect of visual observation of bacterial growth from handprints on healthcare workers' (HCWs) compliance with hand hygiene (HH). Settings Medical and postoperative cardiac surgery units. Design Prospective cohort study. Subject The study included 40 HCWs. Intervention Each HCW was interviewed on 3 separate occasions. The 1st interview was held to obtain a handprint culture before and after a session demonstrating the 7 steps of HH using alcohol-based hand rub, allowing comparison of results before and after HH. A 2nd interview was held 6 weeks later to obtain handprint culture after HH. A 3rd interview was held to obtain a handprint culture before HH. One month before implementation of handprint cultures and during the 12-week study period, monitoring of HCWs for compliance with HH was observed by 2 independent observers. Main Results There was a significant improvement in HH compliance following handprint culture interview (p < 0.001). The frequency of positive cultures, obtained from patients with suspected healthcare-associated infections, significantly declined (blood cultures: p = 0.001; wound cultures: p = 0,003; sputum cultures: p = 0.005). Conclusion The visual message of handprint bacterial growth before and after HH seems an effective method to improve HH compliance.
