Ultrasound-guided aspiration in addition to antibiotics for treatment of liver abscess in children: A randomized controlled trial.

BACKGROUND AND AIM: The criteria for aspiration for pediatric liver abscess are unclear. In this randomized controlled trial, we evaluated the efficacy of ultrasound-guided needle aspiration in addition to antibiotics in children with uncomplicated liver abscess. METHODS: We enrolled 110 children aged 1-18 years (mean [SD] = 7.7 [3.7] years) with uncomplicated liver abscess. The primary outcome was clinical cure at 6 weeks (absence of fever and abdominal pain in the preceding 14 days with reduction in abscess size on ultrasonography). The secondary outcomes were clinical response at 4 weeks, fever resolution time, time to abdominal pain reduction and abdominal tenderness, duration of hospitalization, and treatment failure. RESULTS: Clinical cure at 6 weeks was not significantly different (48/50 [96%] vs 39/46 [85%]; P = 0.082) between aspiration plus antibiotics group and antibiotics only group. The clinical response at 4 weeks was also comparable (49/50 [98%] vs 43/46 [93.5%]; P = 0.347). The mean (SD) of fever resolution time was significantly less in the aspiration plus antibiotics group (198 [90.8] h vs 248.2 [104.6] h; P = 0.014). Time to achieve reduction in abdominal pain (8.32 [3.1] vs 9.46 [3.1] days; P = 0.077) and abdominal tenderness (5.7 [2.4] vs 6.3 [2.3] days; P = 0.242), duration of hospitalization (16.6 [3.9] vs 18.2 [4.4] days; P = 0.07), and adverse event profile (9/50 [18%] vs 14/46 [30%]; P = 0.217) were comparable between the two groups. CONCLUSION: Majority of children with uncomplicated liver abscess achieved clinical cure at 6 weeks with intravenous antibiotics, irrespective of aspiration. However, needle aspiration may slightly reduce the duration of fever and abdominal pain/abdominal tenderness.

Immunogenicity of measles-rubella vaccine administered under India's Universal Immunization Programme in the context of measles-rubella elimination goal: A longitudinal study.

Background & objectives: There is a paucity of data regarding immunogenicity of recently introduced measles-rubella (MR) vaccine in Indian children, in which the first dose is administered below one year of age. This study was undertaken to assess the immunogenicity against rubella and measles 4-6 wk after one and two doses of MR vaccine administered under India's Universal Immunization Programme (UIP). Methods: In this longitudinal study, 100 consecutive healthy infants (9-12 months) of either gender attending the immunization clinic of a tertiary care government hospital affiliated to a medical college of Delhi for the first dose of routine MR vaccination were enrolled. MR vaccine (0.5 ml, subcutaneous) was administered to the enrolled participants (1st dose at 9-12 months and 2nd dose at 15-24 months). On each follow up (4-6 wk post-vaccination), 2 ml of venous blood sample was collected to estimate the antibody titres against measles and rubella using quantitative ELISA kits. Seroprotection (>10 IU/ml for measles and >10 WHO U/ml for rubella) and antibody titres were evaluated after each dose. Results: The seroprotection rate against rubella was 97.5 and 100 per cent and against measles was 88.7 per cent and 100 per cent 4-6 wk after the first and second doses, respectively. The mean (standard deviation) titres against rubella and measles increased significantly (P<0.001) after the second dose in comparison to the levels after the first dose by about 100 per cent and 20 per cent, respectively. Interpretation & conclusions: MR vaccine administered below one year of age under the UIP resulted in seroprotection against rubella and measles in a large majority of children. Furthermore, its second dose resulted in seroprotection of all children. The current MR vaccination strategy of two doses, out of which the first is to be given to infants below one year of age, appears robust and justifiable among Indian children.

Aetiology of hospital-acquired diarrhoea in under-five children from an urban hospital in East Delhi, India.

Background & objectives: Majority of the studies of hospital-acquired diarrhoea conducted in Western countries have focused on the detection of Clostridium difficile in stool samples. Limited Asian and Indian literature is available on hospital-acquired diarrhoea. This study was aimed to describe the aetiological profile for hospital-acquired diarrhoea in children aged below five years. Methods: One hundred children aged one month to five years who developed diarrhoea (≥3 loose stools for >12 h) after hospitalization for at least 72 h were enrolled. Children who were prescribed purgatives or undergoing procedures such as enema and endoscopy or those with underlying chronic gastrointestinal disorders such as celiac disease and inflammatory bowel disease were excluded from the study. Stool samples from the enrolled children were subjected to routine microscopic examination, modified Ziel-Nielson (ZN) staining for Cryptosporidium and culture for various enteropathogens. Multiplex PCR was used to identify the strains of diarrhoeagenic Escherichia coli. Rotavirus detection was done using rapid antigen kit. Toxins (A and B) of C. difficile were detected using enzyme immunoassay. Results: Of the 100 samples of hospital-acquired diarrhoea analysed, diarrhoeagenic E. coli (DEC) was found to be the most common organism, detected in 37 per cent of cases (enteropathogenic E. coli-18%, enterotoxigenic E. coli-8%, enteroaggregative E. coli-4% and mixed infections-7%). Cryptosporidium was detected in 10 per cent of cases. Rotavirus was detected in six per cent and C. difficile in four per cent of cases. Interpretation & conclusions: The findings of this study suggest that the aetiological profile of hospital-acquired diarrhoea appears to be similar to that of community-acquired diarrhoea, with DEC and Cryptosporidium being the most common causes. The efforts for the prevention and management of hospital-acquired diarrhoea should, thus, be directed towards these organisms.

Oral lactase for infantile colic: a randomized double-blind placebo-controlled trial.

BACKGROUND: Infantile colic is a common problem during the first three months of life. This randomized, double-blind, placebo-controlled trial conducted in an urban hospital in Delhi, India evaluated the efficacy and safety of oral lactase in management of infantile colic. METHODS: One hundred sixty-two clinically healthy infants aged < 5 months age [mean (SD) = 63.5 (30.5) days] fulfilling the Rome-IV diagnostic criteria for infantile colic were enrolled. Eligible children were randomly allocated to receive 5 drops of lactase (600 FCC units/mL) (n = 80) or placebo (n = 82) mixed with breast milk or formula feed four times a day for a duration of 4 weeks. Primary outcomes were duration of crying or fussing (min/d), and number of days with colic lasting > 3 h/d; secondary outcomes were parental satisfaction and adverse events. RESULTS: At the end of four weeks, mean (SD) crying or fussing time (min/d) was significantly shorter in infants receiving lactase in comparison to placebo [89.9 (115.2) vs.178.5 (153.2); P = 0.001]. The mean (SD) number of days with colic was also significantly less in the lactase group as compared to placebo group at the end of the treatment [12.1 (7.8) vs 17.6 (8.4); P < 0.001]. By the end of 4th week, parental satisfaction in terms of infant's mood, activity, alertness, comfort and oral intake was better in intervention group. The adverse event profile was comparable between two groups. CONCLUSIONS: Oral lactase treatment in infantile colic results in symptomatic relief in terms of shortening of duration of crying or fussing, and better parental satisfaction. TRIAL REGISTRATION: Clinical trial registry of India (CTRI/2017/12/010930) registered on 20/12/2017.

100 days outcome of severe wasting in hospitalised infants <6 months of age.

OBJECTIVE: To assess the outcome of severe wasting in infants below 6 months of age. DESIGN: A prospective observational study conducted between January 2017 and October 2018. SETTING: A medical college-affiliated hospital in Eastern Delhi, catering mainly to the urban poor population. PARTICIPANTS: All children with severe wasting (weight-for-length Z-score (WLZ) < -3 sd) between 1 and 6 months of age, requiring hospitalisation. RESULTS: Out of fifty children enrolled, during hospitalisation, forty-two (84 %) recovered (WLZ > -3 sd) and discharged; the median (interquartile range (IQR)) duration of stay was 9·5 (6·5, 13·0) d. After 100 d of enrolment, sustained cure (WLZ > -2 SD) could be achieved in only fifteen (30 %) infants, while another fourteen (28 %) recovered from severe wasting, but remained in moderately wasted state (WLZ between -2 and -3 sd). Overall, there were three (6 %) deaths (all during first week of hospitalisation); three (6 %) relapses and fifteen (30 %) defaulters (5, 5, 2, 1 and 2 defaulted during hospitalisation at day 15, day 60, day 75 and day 90, respectively). CONCLUSIONS: The overall recovery rate from severe wasting in infants below 6 months of age was below the acceptable levels. In order to achieve better long-term outcome, community linkage services after discharge from hospital are required for supervised feeding, close monitoring and supportive care.

Aetiology and outcome of acute diarrhoea in children with severe acute malnutrition: a comparative study.

OBJECTIVE: To compare the microbiological profile, clinical course and outcome of acute diarrhoea in children aged <5 years having severe acute malnutrition (SAM) with those of children having normal nutritional status. DESIGN: Cross-sectional comparative study. SETTING: Tertiary-care hospital catering mainly to the urban poor of East Delhi, India. PARTICIPANTS: Children aged <5 years (n 140; seventy with SAM (cases) and seventy with normal anthropometry (controls)) with acute diarrhoea (duration < 14 d). Stool samples were collected for conventional culture, microscopy, acid-fast staining, rotavirus and Cryptosporidium antigen detection, and subtyping of diarrhoeagenic Escherichia coli (DEC). We followed-up these children for persistent diarrhoea and subsequent diarrhoeal episode in the next 3 months. RESULTS: Rotavirus was detected in six (9 %) cases and in fifteen (21 %) controls (P = 0·03; OR = 0·34; 95 % CI 0·12, 0·94). DEC was isolated significantly more in cases compared with controls (93 v. 64 %; P < 0·001; OR = 7·25; 95 % CI 2·57, 20·4). Cryptosporidium was detected in seven (10 %) cases and five (7 %) controls. Total duration of diarrhoea and percentage change in weight after resolution of diarrhoea were comparable between cases and controls. At 3-month follow-up, number of subsequent episodes of diarrhoea and persistent diarrhoea were comparable between the two groups. CONCLUSIONS: Rotavirus was found significantly less frequently, whereas DEC was detected more frequently in children with SAM in comparison to non-malnourished children. To further reduce diarrhoea-related mortality, preventive and therapeutic interventions need to be designed against organisms causing diarrhoea in children with SAM.

Prevalence and predictors of hypocalcaemia in severe acute malnutrition.

OBJECTIVE: To determine the prevalence and predictors of hypocalcaemia in under-five children (1-59 months) hospitalised with severe acute malnutrition (SAM). DESIGN: A cross-sectional study was designed to determine the prevalence of hypocalcaemia among children hospitalised with SAM. Serum Ca and 25-hydroxycholecalciferol (25-(OH)D) were estimated. Hypocalcaemia was defined as serum Ca (albumin-adjusted) <2·12 mmol/l. To identify the clinical predictors of hypocalcaemia, a logistic regression model was constructed taking hypocalcaemia as a dependent variable, and sociodemographic and clinical variables as independent variables. SETTING: A tertiary care hospital in Delhi, between November 2017 and April 2019. PARTICIPANTS: One-hundred and fifty children (1-59 months) hospitalised with SAM were enrolled. RESULTS: Hypocalcaemia was documented in thirty-nine (26 %) children hospitalised with SAM, the prevalence being comparable between children aged <6 months (11/41, 26·8 %) and those between 6 and 59 months (28/109, 25·7 %) (P = 0·887). Vitamin D deficiency (serum 25-(OH)D <30 nmol/l) and clinical rickets were observed in ninety-eight (65·3 %) and sixty-three (42 %) children, respectively. Hypocalcaemia occurred more frequently in severely malnourished children with clinical rickets (OR 6·6, 95 % CI 2·54, 17·15, P < 0·001), abdominal distension (OR 4·5, 95 % CI 1·39, 14·54, P = 0·012) and sepsis (OR 2·6, 95 % CI 1·00, 6·57, P = 0·050). CONCLUSION: Rickets and hypocalcaemia are common in children with SAM. Routine supplementation of vitamin D should be considered for severely malnourished children. Ca may be empirically prescribed to severely malnourished children with clinical rickets, abdominal distension and/or sepsis.

Neonatal mortality risk assessment using SNAPPE- II score in a neonatal intensive care unit.

BACKGROUND: There are many scoring systems to predict neonatal mortality and morbidity in neonatal intensive care units (NICU). One of the scoring systems is SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal extension-II). This study was carried out to assess the validity of SNAPPE-II score (Score for Neonatal Acute Physiology with Perinatal Extension-II) as a predictor of neonatal mortality and duration of stay in a neonatal intensive care unit (NICU). METHODS: This prospective, observational study was carried out over a period of 12 months from June 2015 to May 2016. Two hundred fifty five neonates, who met the inclusion criteria admitted to NICU in tertiary care hospital, BPKIHS Hospital, Nepal were enrolled in the study and SNAPPE-II score was calculated. Receiver Operating Characteristic (ROC) curve was constructed to derive the best SNAPPE-II cut-off score for mortality. RESULTS: A total of 305 neonates were admitted to NICU over a period of one year. Among them, 255 neonates fulfilled the inclusion criteria. Out of 255 neonates, 45 neonates (17.6%) died and 210 were discharged. SNAPPE-II score was significantly higher among neonates who died compared to those who survived [median (IQR) 57 (42-64) vs. 22 (14-32), P < 0.001]. SNAPPE II score had discrimination to predict mortality with area under ROC Curve (AUC): 0.917 (95% CI, 0.854-0.980). The best cut - off score for predicting mortality was 38 with sensitivity 84.4%, specificity 91%, positive predictive value 66.7% and negative predictive value 96.5%. SNAPPE II score could not predict the duration of NICU stay (P = 0.477). CONCLUSION: SNAPPE- II is a useful tool to predict neonatal mortality in NICU. The score of 38 may be associated with higher mortality.

Typical & atypical enteropathogenic Escherichia coli in diarrhoea & their role as carrier in children under five.

BACKGROUND & OBJECTIVES: Multidrug-resistant enteropathogenic Escherichia coli (EPEC) is responsible for a large number of cases of infantile diarrhoea in developing countries, causing failure in treatment with consequent health burden and resulting in a large number of deaths every year. This study was undertaken to determine the proportion of typical and atypical EPEC in under five children with diarrhoea and controls, their function as a carriage and to identify virulent genes associated with them. METHODS: During the study period, 120 stool samples including 80 from controls children were collected and analyzed for the presence of EPEC using standard bacteriological methods. Isolates were subjected to antimicrobial testing by disc diffusion method. Isolates confirmed as E. coli by phenotypic method were further tested for the presence of attaching and effacing (eae) and bundle-forming pilus (bfpA) genes by real-time SYBR Green-based polymerase chain reaction. RESULTS: All isolates were tested for the presence of EPEC. The frequency of typical EPEC was 20 and 16.25 per cent whereas the frequency of atypical EPEC strains was 5 and 23.75 per cent in patients and controls, respectively (PbfpA was seen in 45 and 18.75 per cent isolates of diarrhoeal patients and controls, respectively. INTERPRETATION & CONCLUSIONS: Our results showed that typical EPEC was a common cause of diarrhoea, but at the same time, atypical EPEC was emerging as colonizers in the intestine of children with and without diarrhoea in and around Delhi. Children can be considered asymptomatic carriers of these pathogens and can transmit them to other susceptible children. Adequate steps need to be taken to stop these strains from developing and spreading further.

Research priorities in Maternal, Newborn, & Child Health & Nutrition for India: An Indian Council of Medical Research-INCLEN Initiative.

In India, research prioritization in Maternal, Newborn, and Child Health and Nutrition (MNCHN) themes has traditionally involved only a handful of experts mostly from major cities. The Indian Council of Medical Research (ICMR)-INCLEN collaboration undertook a nationwide exercise engaging faculty from 256 institutions to identify top research priorities in the MNCHN themes for 2016-2025. The Child Health and Nutrition Research Initiative method of priority setting was adapted. The context of the exercise was defined by a National Steering Group (NSG) and guided by four Thematic Research Subcommittees. Research ideas were pooled from 498 experts located in different parts of India, iteratively consolidated into research options, scored by 893 experts against five pre-defined criteria (answerability, relevance, equity, investment and innovation) and weighed by a larger reference group. Ranked lists of priorities were generated for each of the four themes at national and three subnational (regional) levels [Empowered Action Group & North-Eastern States, Southern and Western States, & Northern States (including West Bengal)]. Research priorities differed between regions and from overall national priorities. Delivery domain of research which included implementation research constituted about 70 per cent of the top ten research options under all four themes. The results were endorsed in the NSG meeting. There was unanimity that the research priorities should be considered by different governmental and non-governmental agencies for investment with prioritization on implementation research and issues cutting across themes.

Oral Ondansetron in Management of Dehydrating Diarrhea with Vomiting in Children Aged 3 Months to 5 Years: A Randomized Controlled Trial.

OBJECTIVES: To evaluate the role of oral ondansetron in facilitating successful rehydration of under-5-year-old children suffering from acute diarrhea with vomiting and some dehydration. STUDY DESIGN: Children (n = 170) aged 3 months to 5 years with acute diarrhea with vomiting and some dehydration were enrolled in this double blind, randomized, placebo-controlled trial. The participants were randomized to receive either single dose of oral ondansetron (n = 85) or placebo (n = 85) in addition to standard management of dehydration according to World Health Organization guidelines. Failure of oral rehydration therapy (ORT), administration of unscheduled intravenous fluids, and amount of oral rehydration solution intake in 4 hours were the primary outcomes. Secondary outcome measures included duration of dehydration correction, number of vomiting episodes, adverse effects, and caregiver satisfaction. RESULTS: Failure of ORT was significantly less in children receiving ondansetron compared with those receiving placebo (31% vs 62%; P < .001; relative risk 0.50, 95% CI 0.35-0.72). Almost one-half of the children in the ondansetron group received intravenous fluids compared with those in the placebo group, but it was not statistically significant (P = .074; relative risk 0.56, 95% CI 0.30-1.07). The oral rehydration solution consumption was significantly more in the ondansetron group (645 mL vs 554 mL; mean difference 91 mL; 95% CI: 35-148 mL). Patients in the ondansetron group also showed faster rehydration, lesser number of vomiting episodes, and better caregiver satisfaction. CONCLUSION: A single oral dose of ondansetron, given before starting ORT to children <5 years of age with acute diarrhea and vomiting results in better oral rehydration.

Integrated management of childhood illness (IMCI) strategy for children under five.

BACKGROUND: More than 7.5 million children younger than age five living in low- and middle-income countries die every year. The World Health Organization (WHO) developed the integrated management of childhood illness (IMCI) strategy to reduce mortality and morbidity and to improve quality of care by improving the delivery of a variety of curative and preventive medical and behavioral interventions at health facilities, at home, and in the community. OBJECTIVES: To evaluate the effects of programs that implement the IMCI strategy in terms of death, nutritional status, quality of care, coverage with IMCI deliverables, and satisfaction of beneficiaries. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), including the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register; MEDLINE; EMBASE, Ovid; the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EbscoHost; the Latin American Caribbean Health Sciences Literature (LILACS), Virtual Health Library (VHL); the WHO Library & Information Networks for Knowledge Database (WHOLIS); the Science Citation Index and Social Sciences Citation Index, Institute for Scientific Information (ISI) Web of Science; Population Information Online (POPLINE); the WHO International Clinical Trials Registry Platform (WHO ICTRP); and the Global Health, Ovid and Health Management, ProQuest database. We performed searches until 30 June 2015 and supplemented these by searching revised bibliographies and by contacting experts to identify ongoing and unpublished studies. SELECTION CRITERIA: We sought to include randomised controlled trials (RCTs) and controlled before-after (CBA) studies with at least two intervention and two control sites evaluating the generic IMCI strategy or its adaptation in children younger than age five, and including at minimum efforts to improve health care worker skills for case management. We excluded studies in which IMCI was accompanied by other interventions including conditional cash transfers, food supplementation, and employment. The comparison group received usual health services without provision of IMCI. DATA COLLECTION AND ANALYSIS: Two review authors independently screened searches, selected trials, and extracted, analysed and tabulated data. We used inverse variance for cluster trials and an intracluster co-efficient of 0.01 when adjustment had not been made in the primary study. We used the GRADE (Grades of Recommendation, Assessment, Development and Evaluation Working Group) approach to assess the certainty of evidence. MAIN RESULTS: Two cluster-randomised trials (India and Bangladesh) and two controlled before-after studies (Tanzania and India) met our inclusion criteria. Strategies included training of health care staff, management strengthening of health care systems (all four studies), and home visiting (two studies). The two studies from India included care packages targeting the neonatal period.One trial in Bangladesh estimated that child mortality may be 13% lower with IMCI, but the confidence interval (CI) included no effect (risk ratio (RR) 0.87, 95% CI 0.68 to 1.10; 5090 participants; low-certainty evidence). One CBA study in Tanzania gave almost identical estimates (RR 0.87, 95% CI 0.72 to 1.05; 1932 participants).One trial in India examined infant and neonatal mortality by implementing the integrated management of neonatal and childhood illness (IMNCI) strategy including post-natal home visits. Neonatal and infant mortality may be lower in the IMNCI group compared with the control group (infant mortality hazard ratio (HR) 0.85, 95% CI 0.77 to 0.94; neonatal mortality HR 0.91, 95% CI 0.80 to 1.03; one trial, 60,480 participants; low-certainty evidence).We estimated the effect of IMCI on any mortality measured by combining infant and child mortality in the one IMCI and the one IMNCI trial. Mortality may be reduced by IMCI (RR 0.85, 95% CI 0.78 to 0.93; two trials, 65,570 participants; low-certainty evidence).Two trials (India, Bangladesh) evaluated nutritional status and noted that there may be little or no effect on stunting (RR 0.94, 95% CI 0.84 to 1.06; 5242 participants, two trials; low-certainty evidence) and there is probably little or no effect on wasting (RR 1.04, 95% CI 0.87 to 1.25; two trials, 4288 participants; moderate-certainty evidence).The Tanzania CBA study showed similar results.Investigators measured quality of care by observing prescribing for common illnesses at health facilities (727 observations, two studies; very low-certainty evidence) and by observing prescribing by lay health care workers (1051 observations, three studies; very low-certainty evidence). We could not confirm a consistent effect on prescribing at health facilities or by lay health care workers, as certainty of the evidence was very low.For coverage of IMCI deliverables, we examined vaccine and vitamin A coverage, appropriate care seeking, and exclusive breast feeding. Two trials (India, Bangladesh) estimated vaccine coverage for measles and reported that there is probably little or no effect on measles vaccine coverage (RR 0.92, 95% CI 0.80 to 1.05; two trials, 4895 participants; moderate-certainty evidence), with similar effects seen in the Tanzania CBA study. Two studies measured the third dose of diphtheria, pertussis, and tetanus vaccine; and two measured vitamin A coverage, all providing little or no evidence of increased coverage with IMCI.Four studies (2 from India, and 1 each from Tanzania and Bangladesh) reported appropriate care seeking and derived information from careful questioning of mothers about recent illness. Some studies on effects of IMCI may report better care seeking behavior, but others do not report this.All four studies recorded maternal responses on exclusive breast feeding. They provided mixed results and very low-certainty evidence. Therefore, we do not know whether IMCI impacts exclusive breast feeding.No studies reported on the satisfaction of mothers and service users. AUTHORS' CONCLUSIONS: The mix of interventions examined in research studies evaluating the IMCI strategy varies, and some studies include specific inputs to improve neonatal health. Most studies were conducted in South Asia. Implementing the integrated management of childhood illness strategy may reduce child mortality, and packages that include interventions for the neonatal period may reduce infant mortality. IMCI may have little or no effect on nutritional status and probably has little or no effect on vaccine coverage. Maternal care seeking behavior may be more appropriate with IMCI, but study results have been mixed, providing evidence of very low certainty about whether IMCI has effects on adherence to exclusive breast feeding.

Fortification of staple foods with zinc for improving zinc status and other health outcomes in the general population.

BACKGROUND: Zinc deficiency is a global nutritional problem, particularly in children and women residing in settings where diets are cereal based and monotonous. It has several negative health consequences. Fortification of staple foods with zinc may be an effective strategy for preventing zinc deficiency and improving zinc-related health outcomes. OBJECTIVES: To evaluate the beneficial and adverse effects of fortification of staple foods with zinc on health-related outcomes and biomarkers of zinc status in the general population. SEARCH METHODS: We searched the following databases in April 2015: Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3 of 12, 2015, the Cochrane Library), MEDLINE & MEDLINE In Process (OVID) (1950 to 8 April 2015), EMBASE (OVID) (1974 to 8 April 2015), CINAHL (1982 to April 2015), Web of Science (1900 to 9 April 2015), BIOSIS (1969 to 9 April 2015), POPLINE (1970 to April 2015), AGRICOLA, OpenGrey, BiblioMap, and Trials Register of Promoting Health Interventions (TRoPHI), besides regional databases (April 2015) and theses. We also searched clinical trial registries (17 March 2015) and contacted relevant organisations (May 2014) in order to identify ongoing and unpublished studies. SELECTION CRITERIA: We included randomised controlled trials, randomised either at the level of the individual or cluster. We also included non-randomised trials at the level of the individual if there was a concurrent comparison group. We included non-randomised cluster trials and controlled before-after studies only if there were at least two intervention sites and two control sites. Interventions included fortification (central/industrial) of staple foods (cereal flours, edible fats, sugar, condiments, seasonings, milk and beverages) with zinc for a minimum period of two weeks. Participants were members of the general population who were over two years of age (including pregnant and lactating women) from any country. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the eligibility of studies for inclusion, extracted data from included studies, and assessed the risk of bias of the included studies. MAIN RESULTS: We included eight trials (709 participants); seven were from middle-income countries of Asia, Africa, Europe, and Latin America where zinc deficiency is likely to be a public health problem. Four trials compared the effect of zinc-fortified staple foods with unfortified foods (comparison 1), and four compared zinc-fortified staple foods in combination with other nutrients/factors with the same foods containing other nutrients or factors without zinc (comparison 2). The interventions lasted between one and nine months. We categorised most trials as having unclear or high risk of bias for randomisation, but low risk of bias for blinding and attrition. None of the studies in comparison 1 reported data on zinc deficiency.Foods fortified with zinc increased the serum or plasma zinc levels in comparison to foods without added zinc (mean difference (MD) 2.12 µmol/L, 95% confidence interval (CI) 1.25 to 3.00 µmol/L; 3 studies; 158 participants; low-quality evidence). Participants consuming foods fortified with zinc versus participants consuming the same food without zinc had similar risk of underweight (average risk ratio 3.10, 95% CI 0.52 to 18.38; 2 studies; 397 participants; low-quality evidence) and stunting (risk ratio (RR) 0.88, 95% CI 0.36 to 2.13; 2 studies; 397 participants; low-quality evidence). A single trial of addition of zinc to iron in wheat flour did not find a reduction in proportion of zinc deficiency (RR 0.17, 95% CI 0.01 to 3.94; very low-quality evidence). We did not find a difference in serum or plasma zinc levels in participants consuming foods fortified with zinc plus other micronutrients when compared with participants consuming the same foods with micronutrients but no added zinc (MD 0.03 µmol/L, 95% CI -0.67 to 0.72 µmol/L; 4 studies; 250 participants; low-quality evidence). No trial in comparison 2 provided information about underweight or stunting.There was no reported adverse effect of fortification of foods with zinc on indicators of iron or copper status. AUTHORS' CONCLUSIONS: Fortification of foods with zinc may improve the serum zinc status of populations if zinc is the only micronutrient used for fortification. If zinc is added to food in combination with other micronutrients, it may make little or no difference to the serum zinc status. Effects of fortification of foods with zinc on other outcomes including zinc deficiency, children's growth, cognition, work capacity of adults, or on haematological indicators are unknown. Given the small number of trials and participants in each trial, further investigation of these outcomes is required.

Mid-upper arm circumference v. weight-for-height Z-score for predicting mortality in hospitalized children under 5 years of age.

OBJECTIVE: To compare the performance of mid-upper arm circumference (MUAC) against weight-for-height Z-score (WHZ) for predicting inpatient deaths in children under 5 years of age. DESIGN: Diagnostic test accuracy study. SETTING: Paediatric emergency department of a tertiary care hospital catering to semi-urban and rural population in Delhi, India. SUBJECTS: Hospitalized children (n 1663) aged 6 months to 5 years, for whom discharge outcome was available, were consecutively recruited over 14 months. MUAC (cm), weight (kg) height (cm), clinical details and the outcome were recorded. MUAC (index test) was compared with WHZ based on the WHO growth standards (reference test) for predicting the outcome. RESULTS: One hundred and twenty-four (7 %) children died during hospital stay. Both MUAC < 11·5 cm (adjusted OR (95 % CI): 3·7 (2·43, 5·60), P<0·001) and WHZ<-3 (2·0 (1·37, 2·99), P<0·001) served as independent predictors of inpatient mortality. However, MUAC was a significantly better predictor of mortality compared with WHZ in terms of area under the receiver-operating characteristic curve (MUAC=0·698, WHZ=0·541, P<0·001). MUAC<11·5 cm had the best trade-off of sensitivity and specificity for predicting inpatient mortality. A combination of WHZ<-3 and/or MUAC<11·5 cm did not significantly improve the predictive value over that of MUAC/WHZ, assessed individually. CONCLUSION: MUAC<11·5 cm is a better predictor of mortality in hospitalized under-5 children, as compared with WHZ<-3. It should be measured in all emergency settings to identify the children at higher risk of death.

Oral zinc supplements are ineffective for treating acute dehydrating diarrhoea in 5-12-year-olds.

AIM: Many countries have guidelines recommending the use of oral zinc in acute dehydrating diarrhoea in children aged 2 months to 5 years of age, but no guidelines exist for older children. This study tested how effective existing recommendations are in children from 5 to 12 years of age. METHODS: Children hospitalised with acute dehydrating diarrhoea (n = 134) were randomised to receive 40 mg of oral zinc sulphate tablets or a placebo for 14 days. The primary outcome variable was the time taken for diarrhoea to stop. Secondary outcome variables included time taken for rehydration, duration of hospitalisation and recurrence of diarrhoea in the next 3 months. RESULTS: The median time for resolution of diarrhoea was 60 h in both groups. The zinc group was marginally better, but not statistically significant, for resolution (hazard ratio = 0.89, 95% CI 0.63-1.24), rehydration (hazard ratio = 0.93, 95% CI 0.66-1.32) and hospitalisation (hazard ratio = 0.94, 95% CI 0.67-1.34). The risk ratio of recurrence for zinc versus placebo (95% CI) was 0.65 [0.37-1.23] [p = 0.11]. CONCLUSION: Daily zinc supplements (40 mg for 14 days) in children aged 5-12 years with acute dehydrating diarrhoea did not shorten the duration of diarrhoea or reduce subsequent episodes. Further adequately sized, community-based trials are needed.

Effect of sequencing of complementary feeding in relation to breast-feeding on total intake in infants.

OBJECTIVE: The aim of the present study was to evaluate whether the order of complementary feeding in relation to breast-feeding affects breast milk, semisolid, or total energy intake in infants. METHODS: The present study was designed as a randomized crossover trial. The study was conducted in a tertiary care hospital. The study participants were 25 healthy infants between the ages of 7 and 11 months who were exclusively breast-fed for at least 6 months and were now receiving complementary foods for at least 1 month in addition to breast-feeding. Infants were randomized to follow a sequence of either complementary feeding before breast-feeding (sequence A) or complementary feeding after breast-feeding (sequence B) for the first day (24 hours) of the study period using simple randomization. For the next day, the sequence was reversed for each child. All babies received 3 actively fed complementary food meals per day (morning, afternoon, and evening). A semisolid study diet was prepared in the hospital by cooking rice and pulse with oil using a standard method, ensuring the energy density of at least 0.6 kcal/g. The infants were allowed ad libitum breast-feeding during the observation period. Semisolid intake was directly measured and breast milk intake was quantified by test weighing method. Energy intake from complementary foods was calculated from the product of energy density of the diet served on that day and the total amount consumed. The total energy intake and energy intake from breast milk and complementary foods between the 2 sequences were compared. RESULTS: The mean (standard deviation) energy intake from breast milk during 12 hours of daytime by following sequence A (complementary feeding before breast-feeding) was 132.0 (67.4) kcal in comparison with 135.9 (56.2) kcal in sequence B, which was not statistically different (P = 0.83). The mean (standard deviation) energy consumed from semisolids in sequences A and B was also comparable (88.6 [75.5] kcal vs. 85.5 [89.7] kcal; P = 0.58). The total energy intake during daytime in sequence A was 220.6 (96.2) kcal in comparison with 221.5 (94.0) kcal in sequence B, which was also comparable (P = 0.97). The results related to energy intake through breast milk and total energy intake were not different when insensible losses during feeding were adjusted in both groups. CONCLUSIONS: Altering the sequence of complementary feeding in relation to breast-feeding does not affect total energy intake.

Lactobacillus GG for treatment of acute childhood diarrhoea: an open labelled, randomized controlled trial.

BACKGROUND & OBJECTIVES: Randomized controlled trials in developed countries have reported benefits of Lactobacillus GG (LGG) in the treatment of acute watery diarrhoea, but there is paucity of such data from India. The study was aimed to evaluate the efficacy and safety of Lactobacillus GG in the treatment of acute diarrhoea in children from a semi-urban city in north India. METHODS: In this open labelled, randomized controlled trial 2000 children with acute watery diarrhoea, aged between 6 months to 5 years visiting outpatient department and emergency room of a teaching hospital in north India were enrolled. The children were randomized into receiving either Lactobacillus GG in dose of 10 billion cfu/day for five days or no probiotic medication in addition to standard WHO management of diarrhoea. Primary outcomes were duration of diarrhoea and time to change in consistency of stools. RESULTS: Median (inter quartile range) duration of diarrhoea was significantly shorter in children in LGG group [60 (54-72) h vs. 78 (72-90) h; P<0.001]. Also, there was faster improvement in stool consistency in children receiving Lactobacillus GG than control group [36 (30-36) h vs. 42 (36-48) h; P<0.001]. There was significant reduction in average number of stools per day in LGG group (P<0.001) compared to the control group. These benefits were seen irrespective of rotavirus positivity in stool tests. INTERPRETATION & CONCLUSIONS: Our results showed that the use of Lactobacillus GG in children with acute diarrhoea resulted in shorter duration and faster improvement in stool consistency as compared to the control group.

Diagnostic Accuracy of Waist Circumference and Waist-to-Height Ratio for Moderate and Severe Acute Malnutrition in Under-5 Children.

OBJECTIVE: To determine the most appropriate cut-off values of Waist Circumference (WC) and Waist-to-Height Ratio (WHtR) for diagnosing moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) in under-five children. METHODS: This cross-sectional diagnostic accuracy study was conducted between January 2021 and August 2022 in the Department of Pediatrics of a tertiary hospital in Delhi. Children aged 6 months to 5 years attending the outpatient or emergency services were included in the study. Detailed clinical evaluation and anthropometry including measurement of WC were done at enrollment. Body mass index (BMI) and WHtR were calculated. Malnutrition was classified as per the WHO criteria. Receiver operating characteristic curves (sensitivity, specificity) for WC and WHtR (absolute values) were drawn against the standard test of WHO definitions for MAM and SAM to determine the most appropriate cut-offs for diagnosing MAM and SAM. RESULTS: 1500 children with a median (IQR) age of 29 (14, 43) months were enrolled; 21% children had MAM and 11% had SAM as per the WHO criteria. WC < 44.5 cm (sensitivity 74.1%, specificity 71.1%) and WHtR < 0.565 (sensitivity 75.6%, specificity 33.7%) were the best cut-offs to identify MAM, whereas WC < 42.3 cm (sensitivity 67.5%, specificity 81.3%) and WHtR < 0.563 (sensitivity 81.3%, specificity 33.4%) were the best cut-offs to diagnose SAM. CONCLUSION: Waist circumference (< 44.5 cm for MAM; < 42.3 cm for SAM) had a reasonably good sensitivity and specificity for diagnosing MAM and SAM, but the same was not true for WHtR.
