Abstract
Background There are an estimated 2.7 million children living within institutionalized care worldwide. This review aimed to evaluate currently available data on the nutrition status of children living within institutionalized care. Methods We searched four databases (Pubmed/Medline, CINHAL Plus, Embase and Global Health Database) for relevant articles published from January 1990 to January 2019. Studies that included information on anthropometry or micronutrient status of children living within institutionalized care were eligible for inclusion. The review is registered on PROSPERO: CRD42019117103. Results From 3,602 titles screened, we reviewed 98 full texts, of which 25 papers were eligible. Two (8%) studies reported data from multiple countries, nine (36%) were from Asia, four (16%) from Africa, three (12%) from Eastern Europe, four (16%) from the European Union and one (4%) from each of the remaining regions (Middle East, South America and the Caribbean). Twenty-two (88%) were cross sectional. Ten (40%) of the studies focused on children >5 years, seven (28%) on children <5 years, seven (28%) covered a wide age range and one did not include ages. Low birth weight prevalence ranged from 25–39%. Only five (20%) included information on children with disabilities and reported prevalence from 8–75%. Prevalence of undernutrition varied between ages, sites and countries: stunting ranged from 9–72%; wasting from 0–27%; underweight from 7–79%; low BMI from 5–27%. Overweight/obesity ranged from 10–32% and small head circumference from 17–41%. The prevalence of HIV was from 2–23% and anemia from 3–90%. Skin conditions or infections ranged from 10–31% and parasites from 6–76%. Half the studies with dietary information found inadequate intake or diet diversity. Younger children were typically more malnourished than older children, with a few exceptions. Children living within institutions were more malnourished than community peers, although children living in communities were also often below growth standards. High risk of bias was found. Conclusions This study highlights the limited amount of evidence-based data available on the nutritional status of children in institutions. Of the studies reviewed, children living within institutionalized care were commonly malnourished, with undernutrition affecting young children particularly. Micronutrient deficiencies and obesity were also prevalent. Data quality was often poor: as well as suboptimal reporting of anthropometry, few looked for or described disabilities, despite disability being common in this population and having a large potential impact on nutrition status. Taken together, these findings suggest a need for greater focus on improving nutrition for younger children in institutions, especially those with disabilities. More information is needed about the nutritional status of the millions of children living within institutionalized care to fully address their right and need for healthy development.

Abstract
The aim of this study was to describe the experience of 452 children and adults with a severe developmental disability who presented to a multidisciplinary clinic with swallowing, nutritional, and gastrointestinal problems. Data were obtained by chart review. Two hundred and ninety-four children (age range 7 mo-19 y, 173 males, 121 females) and 158 adults (age range 18-53 y; 90 males, 68 females) were assessed over 5 years. One hundred and eighty-two children and 86 adults had cerebral palsy. Approximately 90% were wheelchair dependent and totally dependent on caregivers for feeding; 60% had epilepsy. Pulmonary aspiration was identified by oesophageal videofluoroscopy in 41% of 174 children and 47% of 34 adults. Chronic oesophagitis and Helicobacter pylori were found in 57% of 182 children and 76% of 66 adults undergoing endoscopy. Chronic suppurative lung disease was identified by computerized axial tomography in 94% of 62 children and all six adults studied. Most patients improved with simple interventions. However, gastrostomy was recommended in 140 children and performed in 91, and in 10 adults but performed in seven, whereas fundoplication was recommended in 111 children and performed in 74, and in six adults but performed in two. In conclusion, chronic oesophagitis, pulmonary aspiration, and chronic lung disease were identified in many patients with a severe developmental disability.

Abstract
BACKGROUND Data of Helicobacter pylori prevalence in children and its risk factors provide clues to the health authority to estimate burden of H. pylori-associated diseases usually encountered in adulthood and facilitate healthcare planning. MATERIALS AND METHODS A cross-sectional population-based study was conducted in Chinese children in elementary and high schools. Schools were selected from all three major areas of Hong Kong. H. pylori infection was defined by a positive (13)C-urea breath test. Study subjects were stratified into six age groups for estimation of prevalence. Potential risk factors were analyzed from data of self-administered questionnaires. RESULTS A total of 2480 children (aged 6-19, male: 47.3%) participated in the study. Overall, 324 (13.1%) were positive for H. pylori. There was no difference in prevalence between sexes, and no statistical trend in the prevalence across the six age groups. Multivariate logistic regression identified lack of formal education of mother (OR = 2.43, 95%CI 1.36-4.34), family history of gastric cancer (OR = 2.19, 95%CI 1.09-4.41), and household member > 5 (OR = 1.57, 95%CI 1.12-2.19) to be positively associated with H. pylori infection in our children. CONCLUSIONS The H. pylori prevalence of Hong Kong children is comparable to the data of developed countries. The association with family history of gastric cancer justifies further study to investigate the cost-benefit of community screening program for such children to decrease the incidence of gastric cancer in adulthood.

Abstract
Eighty-four children with mental retardation (34 boys, 50 girls; age range 2-18 years, median 6 years) and 84 age- and gender-matched outpatient controls were studied. All children were living at home, had never stayed in an institution, and came from the same urban area. Seropositivity for Helicobacter pylori was found in 42 (50%) of 84 mentally retarded children and 16 (19%) of 84 controls (p < 0.01). Socio-economic factors did not differ between the two groups. The findings indicated that a higher prevalence of H. pylori infection occurs in children with mental retardation, regardless of whether they are institutionalised.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection has been linked to gastritis, diarrhea, peptic ulcers, failure-to-thrive, anemia, as well as predisposition to gastric malignancies. Because many internationally adopted children have diarrhea, failure-to-thrive, and anemia on arrival to the US, we determined the prevalence of HP antibodies among these children. METHODS Serum samples from 226 unselected children from 18 countries who were evaluated in the International Adoption Clinic at New England Medical Center were tested for antibodies to H. pylori. The results of serologic screening were analyzed in relation to age at adoption, site of residence prior to adoption, weight and height, and the presence or absence of anemia, diarrhea, or intestinal parasites. RESULTS 31% of internationally adopted children had antibodies to H. pylori. The presence of H. pylori-antibodies was associated with residence in an orphanage (vs. foster care) prior to adoption, older age at adoption, and coinfection with intestinal parasites. No direct effects on height or weight were identified; no associations with diarrhea or anemia were found. CONCLUSIONS Internationally adopted children have a high incidence of exposure to H. pylori, as diagnosed serologically. Residence in an orphanage (compared with foster care), older age at adoption, and coinfection with intestinal parasites were more common among children seropositive for anti-H. pylori antibodies.

Abstract
In 1982, Helicobacter pylori (formerly Campylobacter pylori) was identified as a pathogenic factor in peptic ulcer disease by researchers from Australia. Because only a small number of studies of H. pylori infection have been conducted in people with intellectual disability (ID), and none of these were done in Israel, the present authors decided to conduct a pilot study on its prevalence in this population. The Israeli Division for Mental Retardation provides services to over 6000 people in 54 residential care centres (or institutions), and one centre in the south of the country with kibbutz-style living arrangements was selected for this pilot study. The study was performed as part of the yearly routine medical examination of all residents, and blood specimens were drawn for IgG antibodies to H. pylori (ELISA). Out of the 47 individuals screened, 75% (n=36) were seropositive. In addition to the reported high rates of H. pylori infection in residents with ID living in large facilities, the present pilot study suggests that people with ID living in smaller, kibbutz-style arrangements are also at high risk.

Abstract
In institutionalized adults with intellectual disability (ID), Helicobacter pylori infection occurs at approximately twice the rate it appears in the general population, and it may be responsible for the twofold higher rates of peptic ulcer disease and gastric cancer in this population. Medical, behavioural and additional environmental factors, as well as level of ID, may be related to the risk of infection with H. pylori. One hundred and sixty-eight adults with ID who were currently, had previously been or had never been institutionalized underwent a biopsychosocial evaluation. This included assessment of: level of ID using the Adaptive Behaviour Scale (ABS) Part I; levels of maladaptive behaviour using the ABS Part II; demographic, medical and environmental factors; as well as H. pylori tests using serology and faecal antigen. The overall rates of past or current infection with H. pylori in institutionalized and previously institutionalized participants were about twice that of the overall group of never-institutionalized participants, i.e. 87% and 79% compared to 44%, respectively (P < 0.001). The rates of H. pylori infection appeared to increase with age in the never-institutionalized group, but were consistently high across all ages in the other groups. The rate of infection was higher in those institutionalized for more than 5 years (95% versus 76%, P=0.02), in those with flatmates with excessive oral secretions (65% versus 21%, P < 0.001) or faecal incontinence (67% versus 27%, P < 0.001), and in those with more chronic illness and medications. All mean domain scores of the ABS Part I (Intellectual Disability) were significantly lower (indicating more severe ID) in the group currently infected with H. pylori compared to their non-infected counterparts. The majority of mean domain scores of the ABS Part II (Behaviour) were also worse, with half of these score differences reaching statistical significance in the currently infected group. The presence of alarm symptoms (e.g. vomiting, weight loss, haematemesis and melena), iron deficiency and body mass index were not significantly different in currently infected subjects. Adults with ID appear to be particularly at risk of infection with H. pylori. Environmental associations with infection include past or current institutionalization, a longer period of institutionalization, living with flatmates with excessive oral secretions and faecal incontinence. Medical associations include chronic disease and more medications, but not alarm symptoms or body mass index. Demographic associations may include increasing age in never-institutionalized adults, but no age effect in currently or previously institutionalized individuals. Psychosocial associations include more severe ID and maladaptive behaviour with current infection.

Abstract
Gastrointestinal issues are a major chronic problem in 80 to 90% of children with cerebral palsy and in children with neurodevelopmental disabilities who are at special risk of developing malnutrition because of uncoordinated swallowing, gastroesophageal reflux, and constipation. In addition to poor linear growth, there is a decrease in muscle strength and coordination, impaired cerebral function leading to decreased motivation and energy. Significant neurodevelopmental progress can be achieved with improved nutritional status. A multidisciplinary approach, with input from neurologists, gastroenterologists, nurses, occupational therapists, and dieticians, can make a major contribution to the medical wellbeing and quality of life of these children. Different neurological diseases ( eg, spinal dysraphism, syringomyelia, tethered cord syndromes) can give rise to gastrointestinal dysfunction and symptoms that may need different gastrointestinal or surgical management. The introduction of new drugs, including proton pump inhibitors and innovative endoscopic and surgical techniques in the management of gastroesophageal reflux disease and constipation also may have an impact on the treatment of neurologically handicapped children in the future.

Abstract
Advancing knowledge of the existence of Helicobacter pylori and its association with gastrointestinal tract malignancy, and previous research showing higher-than-expected gastrointestinal tract malignancy in institutionalized adults with intellectual disability (ID) prompted a review of all deaths as a result of cancer in the Stoke Park group of hospitals for people with ID between 1946 and 1996. A 50-year, retrospective case note analysis of all deaths from cancer in an institution for people with ID was undertaken. Death from stomach cancer accounted for up to 48% of all cancer deaths. A further 25 residents had died of perforated stomach ulcers. The higher proportion of deaths specifically caused by stomach cancer in a population with ID has not been noted previously. It is postulated that the high levels of H. pylori infection found in institutionalized populations may be instrumental in this higher mortality rate and that the closure of the institutions without evaluation of H. pylori status transfers the problem unresolved to the community. Existing guidelines for the screening and eradication of H. pylori developed for the general population are inadequate when applied to people with ID, and therefore, the value of population screening and mass eradication programmes is explored.

Abstract
Across populations of children, Helicobacter pylori prevalence ranges from under 10% to over 80%. Low prevalence occurs in the U.S., Canada, and northern and western Europe; high prevalence occurs in India, Africa, Latin America, and eastern Europe. Risk factors include socioeconomic status, household crowding, ethnicity, migration from high prevalence regions, and infection status of family members. H. pylori infection is not associated with specific symptoms in children; however, it is consistently associated with antral gastritis, although its clinical significance is unclear. Duodenal ulcers associated with H. pylori are seldom seen in children under 10 years of age. H. pylori-infected children demonstrate a chronic, macrophagic, and monocytic inflammatory cell infiltrate and a lack of neutrophils, as compared with the response observed in adults. The effect of H. pylori infection on acid secretion in children remains poorly defined. The events that occur during H. pylori colonization in children should be studied more thoroughly and should include urease activity, motility, chemotaxis, adherence, and downregulation of the host response. The importance of virulence determinants described as relevant for disease during H. pylori infection has not been extensively studied in children. Highly sensitive and specific methods for the detection of H. pylori in children are needed, especially in younger pediatric populations in which colonization is in its early phases. Criteria for the use of eradication treatment in H. pylori-infected children need to be established. Multicenter pediatric studies should focus on the identification of risk factors, which can be used as prognostic indicators for the development of gastroduodenal disease later in life.

Abstract
BACKGROUND Helicobacter pylori infection appears to be contracted mainly in childhood, and it is associated with disadvantaged socioeconomic conditions, overcrowding, and living in institutions. In this study we determined the seroprevalence of H. pylori among elderly patients (age > or = 70 years) admitted to a major medical center in Israel, and studied the relationship between seroprevalence of H. pylori and the duration of stay in a nursing home prior to the admission. PATIENTS AND METHODS Whole blood from 182 consecutive patients hospitalized at the Rabin Medical Center was tested for the presence of anti-H. pylori IgG using Helisal Rapid Blood Test kit (Cortecs Diagnostics). Multivariate logistic regression analysis was used to study the relation between H. pylori seropositivity and possible predictive factors such as age, gender and duration of stay in a nursing home. RESULTS Of the 182 patients included in the study, 80 (44%) were living in nursing homes (NH) and 102 (56%) were living in their own homes (H) prior to admission. Subjects that stayed in nursing homes for more than 15 months were significantly more likely to be seropositive than subjects with a shorter duration of stay (84% and 63% respectively, p = 0.03). Using a multivariate logistic regression analysis on both the NH group and the whole group, seropositivity was found to be significantly associated with duration of stay in a nursing home (p = 0.03 and p = 0.01 respectively). Seropositivity was not associated with age in either group. CONCLUSIONS Living in a nursing home is associated with increased risk for H. pylori infection in the elderly. There is a strong correlation between the duration of stay in a nursing home and the prevalence of H. pylori infection.
