BackgroundThe World Health Organization recommends that human growth should be monitored with the use of international standards. However, in obstetric practice, we continue to monitor fetal growth using numerous local charts or equations that are based on different populations for each body structure. Consistent with World Health Organization recommendations, the INTERGROWTH-21st Project has produced the first set of international standards to date pregnancies; to monitor fetal growth, estimated fetal weight, Doppler measures, and brain structures; to measure uterine growth, maternal nutrition, newborn infant size, and body composition; and to assess the postnatal growth of preterm babies. All these standards are based on the same healthy pregnancy cohort. Recognizing the importance of demonstrating that, postnatally, this cohort still adhered to the World Health Organization prescriptive approach, we followed their growth and development to the key milestone of 2 years of age.ObjectiveThe purpose of this study was to determine whether the babies in the INTERGROWTH-21st Project maintained optimal growth and development in childhood.Study DesignIn the Infant Follow-up Study of the INTERGROWTH-21st Project, we evaluated postnatal growth, nutrition, morbidity, and motor development up to 2 years of age in the children who contributed data to the construction of the international fetal growth, newborn infant size and body composition at birth, and preterm postnatal growth standards. Clinical care, feeding practices, anthropometric measures, and assessment of morbidity were standardized across study sites and documented at 1 and 2 years of age. Weight, length, and head circumference age- and sex-specific z-scores and percentiles and motor development milestones were estimated with the use of the World Health Organization Child Growth Standards and World Health Organization milestone distributions, respectively. For the preterm infants, corrected age was used. Variance components analysis was used to estimate the percentage variability among individuals within a study site compared with that among study sites.ResultsThere were 3711 eligible singleton live births; 3042 children (82%) were evaluated at 2 years of age. There were no substantive differences between the included group and the lost-to-follow up group. Infant mortality rate was 3 per 1000; neonatal mortality rate was 1.6 per 1000. At the 2-year visit, the children included in the INTERGROWTH-21st Fetal Growth Standards were at the 49th percentile for length, 50th percentile for head circumference, and 58th percentile for weight of the World Health Organization Child Growth Standards. Similar results were seen for the preterm subgroup that was included in the INTERGROWTH-21st Preterm Postnatal Growth Standards. The cohort overlapped between the 3rd and 97th percentiles of the World Health Organization motor development milestones. We estimated that the variance among study sites explains only 5.5% of the total variability in the length of the children between...
Introduction: 177Lu-DOTATATE-based peptide receptor radionuclide therapy (PRRT) is a promising therapy for metastatic and/ inoperable pheochromocytoma and paraganglioma (PPGL). We aim to evaluate the efficacy and safety of and identify predictors of response to 177Lu-DOTATATE therapy in metastatic and/ inoperable PPGL. Methods: This retrospective study involved 15 patients of metastatic or unresectable PPGL, who received 177Lu-DOTATATE PRRT therapy. Clinical, biochemical (Plasma free normetanephrine), and radiological (anatomical and functional) responses were compared before and after the last therapy. Results: A total of 15 patients PCC (4), sPGL (4), HNPGL (5), PCC+sPGL (1), HNPGL+sPGL (1) were included. The median duration of follow up was 27 (range: 11-62) months from the start of PRRT. Based on the RECIST (1.1) criteria, progressive disease was seen in three (20%), stable disease in eight (53 %), partial response in one (7%), and minor response in three (20%) and controlled disease in 12 (80%). On linear regression analysis presence of PGL (p= 0.044) and baseline SUVmax >21 (p < 0.0001) were significant positive predictors of early response to PRRT. Encouraging safety profiles were noted with no long term nephrotoxicity and haematotoxicity. Conclusion: 177Lu-DOTATATE therapy is an effective and safe modality of treatment for patients with metastatic/inoperable PPGL. Although it is not prudent to withhold PRRT in metastatic PPGL with baseline SUVmax < 21, baseline SUVmax >21 can be used to predict early response to PRRT.
Context: Insulinoma needs accurate preoperative localization for minimally invasive surgery. Exendin-4-based imaging has shown promising results. Objective: To evaluate performance parameters of exendin-4-based imaging in insulinoma localization and compare with other imaging modalities. Design: Retrospective cross-sectional study. Patients: We report 14 patients with endogenous hyperinsulinemic hypoglycaemia (EHH) managed at our centre; in whom, the final diagnosis was insulinoma (n = 11), Munchausen syndrome (MS) (n = 2) and inconclusive (n = 1). Retrospective reporting of CECT, 68 Ga-DOTATATE PET/CT and 68 Ga-NODAGA-exendin-4-PET/CT was done. With per-lesion analysis, performance parameters were calculated for the histopathological diagnosis of insulinoma. Main Outcome Measures: True positive (TP), false positive (FP), false negative (FN), true negative (TN), sensitivity (Sn), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) for insulinoma localization. Results: In our cohort, 12 histopathologically proven insulinoma lesions [(TP): 11 primary lesions, 1 metastasis] were detected in 11 patients, whereas two patients had MS (TN). Sn and PPV were 75% and 100%, 33.3% and 80% and 83.3% and 71.4% for CECT, 68 Ga-DOTATATE PET/CT and 68 Ga-NODAGA-exendin-4-PET/CT, respectively. With exendin-4-based imaging, FP uptake in normal pancreatic tissue and FN results in the pancreatic tail lesion was seen. In one patient, TN result suggested the correct diagnosis of MS. Conclusion: 68 Ga-NODAGA-exendin-4-PET/CT has higher sensitivity than 68 Ga-DOTATATE PET/CT and CECT for insulinoma localization. FP uptake in normal pancreas and FN result in tail lesions are limitations of currently utilized exendin-4-based imaging.
Background. Liraglutide in a 3.0 mg subcutaneous dose daily is approved for weight reduction. Objectives. Objectives are to evaluate the efficacy and safety of liraglutide 3.0 mg in patients with overweight and obesity irrespective of diabetic status. Methods. We conducted an electronic database search in PubMed, Embase, and https://ClinicalTrial.gov to identify all randomized control trials (RCTs) that evaluated the efficacy and safety of liraglutide 3.0 mg dose compared to placebo in overweight (≥27 kg/m2) and obese (≥30 kg/m2) patients above 18 years of age. Results. We compared the pooled estimate of the study results between liraglutide 3.0 mg groups and placebo groups both in diabetic and nondiabetic patients. The efficacy outcomes that were found to be significant among respective studies involving nondiabetic patients vs. diabetic patients were mean change in body weight from baseline: 12 studies [MD = −5.04 kg (95% CI = −5.60, −4.49), P < 0.001 , I2 = 92.95%] vs. 2 studies [MD = −4.14 kg (95% CI = −4.95, −3.32), P < 0.001 , I2 = 0%], reduction in waist circumference from baseline: 8 studies [MD = −3.64 cm (95% CI = −4.43, −2.85), P < 0.001 , I2 = 96.5%] vs. 2 studies [MD = −3.11 cm (95% CI = −3.88, −2.34), P < 0.001 , I2 = 0%], BMI reduction from baseline: 5 studies [MD = −1.95 kg/m2 (95% CI = −2.22, −1.68) vs. 1 study [MD = −1.86 kg/m2 (95% CI = −2.14, −1.57), P < 0.001 , I2 = 0%, P < 0.001 , I2 = 95.6%], proportion of patients losing more than 5% of weight loss from baseline: 8 studies [RR = 2.21, (95% CI = 1.89, 2.58), P = 0.03 , I2 = 59.02%] vs. 2 studies [RR = 2.34, (95% CI = 1.93, 2.85), P = 0.39 , I2 = 0.00%], and 10% weight loss from baseline: 7 studies [RR = 3.36, (95% CI = 1.92, 5.91), P = 0.00 , I2 = 87.03%] vs. 2 studies [RR = 3.64, (95% CI = 2.46, 5.40), P = 0.81 , I2 = 0.00%]. Safety outcome assessment with use of liraglutide 3.0 mg compared with placebo in respective nondiabetic vs. diabetic patients revealed significant proportion of patients experiencing the adverse events: 9 studies [RR = 1.11, (95% CI = 1.04, 1.18), P = 0.00 I2 = 79.15%] vs. 2 studies [RR = 1.06, (95% CI = 1.01, 1.11), P = 0.42 , I2 = 0.03%] but similar risk of serious adverse events: 9 studies [RR = 1.03, (95% CI = 0.70, 1.51), P = 0.26 , I2 = 18.54%] vs. 2 studies [RR = 1.11, (95% CI = 0.67, 1.84), P = 0.25 , I2 = 23.77%] and TDAEs: 4 studies [RR = 0.89, (95% CI = 0.35, 2.28), P = 0.03 , I2 = 61.89%] vs. 1 study [RR = 2.53, (95% CI = 1.00, 6.37)]. However, the pooled estimates irrespective of the glycaemic status were mean change in body weight from baseline: 14 RCT [MD = −4.91 kg (95% CI = −5.43, −4.39), P < 0.001 , I2 = 92.35%], reduction in waist circumference from baseline: 10 studies [MD = −3.55 cm, (95% CI = −4.21, −2.89), P < 0.001 , I2 = 94.99%], BMI reduction from baseline: 6 studies [MD = −1.86 kg/m2, (95% CI = −2.14, −1.57), P < 0.001 , I2 = 96.14%], and proportion of patients losing more than 5% and 10% of weight from baseline: [RR = 2.23, (95% CI = 1.98, 2.52), P < 0.001 , I2 = 48.87%] and [RR = 3.28, (95% CI = 2.23, 4.83), P < 0.001 , I2 = 78.98%], respectively. Also, the proportion of patients experiencing the adverse event was more with liraglutide 3.0 mg compared with placebo 11 study [RR = 1.09, (95% CI = 1.04, 1.15), P < 0.01 , I2 = 76.60%] and similar risk for both serious adverse events: 11 studies [RR = 1.09, (95% CI = 1.04, 1.15), P < 0.01 , I2 = 76.60%] and TDAEs: 5 studies [RR = 1.14, (95% CI = 0.50, 2.60), P < 0.01 , I2 = 64.93%] with liraglutide compared with placebo. Conclusions. Liraglutide in 3.0 mg subcutaneous dose demonstrated significant weight reduction with a reasonable safety profile for patients with overweight or obesity regardless of diabetic status compared to placebo.
