Management of Severely Malnourished Children Aged 6 - 59 Months Hospitalized in the Pediatric Ward of Kayanza Hospital/Burundi

The implementation of WHO guidelines has significantly reduced hospital mortality due to severe malnutrition. Nevertheless, severe acute malnutrition in children under five remains a major public health problem in all low-income countries and is little studied. The study aimed to assess the nutritional status and quality of management of severe acute malnutrition in children aged 06 to 59 months hospitalized in the pediatric ward of Kayanza Hospital. This is a prospective study with descriptive and analytical aims over 6 months from February 10 to July 9, 2023. All children aged 6 to 59 months admitted for severe acute malnutrition are included in this study. The results show that the most affected age group is 12 to 23 months (42.55%). Marasmus is the most common clinical form, at 70.2%. Housewives and mothers from rural areas are the most affected, with rates ranging from 69.14% to 91.49%. The study shows that the reasons for consultation are respectively: edema (29.78%), diarrhea (26.59%), vomiting (19.14%), and fever (14.89%). Dehydration and hypothermia were the main complications observed in 45.74% and 22.34% respectively. Medical treatment was provided by antibiotics (44.68%), artesunate (31.91%), and resomal (21.27%). Nutritional treatment consisted of F75 100% milk and F100 100% milk. Pathologies observed were: anemia 38.29%, malaria 37.23%, urinary tract infection 12.7%, measles 11.7%. The national protocol for integrated management of acute malnutrition (PCIMA) was followed. This study shows that 72.3% of children were successfully treated, with 9.5% dropping out and dying, and 8.5% not responding. We found that malnutrition remains a public health problem, affecting mostly children aged 12 to 24 months. The main complications or pathologies associated with malnutrition are diarrhea, malaria, and fever, and the majority of children suffer from marasmus.

Norovirus Infection and Histo-blood Group Antigens in Children Hospitalized with Diarrhea in Lulong and Chenzhou in China

Norovirus （NOV） is a pathogen that commonly causes viral diarrhea in children. Studies indicate that NoV recognizes human histo-blood group antigens （HBGAs） as cell attachment factors. In order to explore the correlation between of NoV infection and HBGAs, a cross-sectional study was conducted in children less than five years old who were hospitalized with diarrhea in two areas of China between November 2014 and February 2015. Of the paired stool and saliva samples taken from 424 children,

Biological Markers of Undernutrition and Risk of Complications in Children Hospitalized at the Teaching Hospital of Brazzaville

Introduction: Undernutrition is a condition frequently encountered in pediatrics. It leads to an increased morbidity and mortality regardless of the underlying condition or other risk factors such as age. In countries with limited resources such as ours, the diagnosis of undernutrition is often limited to the clinical presentation, and the contribution of biology is not often taken into account. Objectives: To establish the relationship between anthropometric parameters and biological markers in the diagnosis and classification of undernutrition and to assess the risk of infectious complications during undernutrition in children. Materials and Methods: A cross-sectional study conducted in Brazzaville among undernourished children aged 1 - 59 months between October 2018 and April 2019. Clinical diagnosis was based on WHO growth charts. The CRP, orosomucoid, albumin and transthyretin were obtained using the Cobas c311 analyzer, which enabled the calculation of Prognostic Inflammatory and Nutritional Index (PINI). The comparison of the means of the biological markers used the Student’s t-test, the risk of infectious complications the chi-square. The correlation of the diagnostic value of Z-score weight/height and PINI was also investigated. The significance level was set at 0.05. Results: Of the 95 children enrolled 63 (66.3%) were clinically severely malnourished, including 26 acute (41.3%) and 37 chronic (58.7%). The PINI revealed severe undernutrition in 85 children (89.4%) including 50 acute (58.8%) and 35 chronic (41.2%). CRP and orosomucoid were statistically higher in severe acute undernutrition (p Conclusion: Anthropometric parameters have a front-line advantage for assessing and classifying undernutrition. However, biological markers of undernutrition with PINI should be systematized in the diagnosis and management of undernutrition.

Clinical and Epidemiological Aspects of Severe Acute Malnourished Children from 6 to 59 Months Hospitalized in a Secondary Hospital in Mali

Introduction: Malnutrition acts on the immune system and thus increases susceptibility to infections. Infections can weaken the body and cause malnutrition, so we speak of a vicious circle between malnutrition and infection. Objective: To study the clinical and epidemiological aspects of severe acute malnutrition in children aged 6 to 59 months. Methodology: This was a prospective and descriptive study extending from July 1, 2018 to June 30, 2019. All severely acute malnourished children aged 6 to 59 months were hospitalized at URENI whose parents or careers accepted their participation in the study. Results: Severe acute malnutrition was diagnosed in 398 of the 671 hospitalized children, i.e. 59.3%. The median age was 15.33 months (2 months - 59 months). The sex ratio was 1.03 (M = 50.8 F = 49.2). Eighty-seven percent of mothers were housewives. Parents were uneducated in 49.3% for mothers and 51.8% for fathers. Marasmus represented 93.5% of cases, children diagnosed with HIV+ represented 6.3% with exclusively HIV1 (100%). Pneumopathy was most frequently associated pathology with 33.4%. The duration of hospitalization was less than 7 days in 67.6% of cases and 93.3% of children had been successfully treated. The mortality rate was 4%. Conclusion: Malnutrition still remains a public health problem affecting mainly children aged 13 to 24 months, mainly from low-income families.

Relationship between negative emotions and perceived support among parents of hospitalized,critically ill children

Objectives:The purpose of this study was to describe relationships between negative emotions and perceived emotional support in parents of children admitted to the pediatric intensive care unit(PICU).Methods:This cross-sectional descriptive study conducted face-to-face interviews between January 2019 and January 2020.Study variables included depression(PHQ-9 Scale),anxiety(Emotional Distress-Anxiety-Short Form 8a),anger(Emotional Distress-Anger-Short Form 5a),fear(Fear-Affect Computerized Adaptive Test),somatic fear(Fear-Somatic Arousal-Fixed Form),loneliness(Revised 20-item UCLA Loneliness Scale),and perceived emotional support(Emotional Support-Fixed Form).Results:Eighty parents reported symptoms of depression 8.00(4.00,13.75),anxiety(23.43±7.80),anger(13.40±5.46),fear(72.81±27.26),somatic fear 9.00(6.00,12.75),loneliness(39.35±12.00),and low perceived emotional support(32.14±8.06).Parents who were young,single,low-income,and with limited-post secondary education reported greater loneliness and lower perceived emotional support.Fear correlated with depression(r=0.737,P<0.01)and anxiety(r=0.900,P<0.01).Inverse relationships were discovered between perceived emotional support and loneliness(r=-0.767,P<0.01),anger(r=-0.401,P<0.01),and depression(r=-0.334,P<0.01).Conclusions:The cluster of negative emotions identified will serve as potential targets for future interventions designed to enhance support for parents of critically ill children.

Blood Count Characteristics of Children Hospitalized in General Pediatrics at the Gabriel Touré Teaching Hospital

Objective: The main objective was to study the disturbances of the Blood Count of children hospitalized in the general pediatric of the Gabriel Touré teaching hospital. Methods: This was a prospective and descriptive study conducted from September 1 to November 30, 2018 in the general pediatrics department of the Gabriel Touré teaching hospital in Bamako. Data were collected on patient records using a survey sheet. Results: We collected 512 files of children out of 1030 admissions during the study period;the rate of completion of the blood count is 50%. The male sex was predominant with a sex ratio of 1.3. The majority of patients were under 5 years old (58%). The majority of fathers (56%) and mothers (64%) of children had no education;they are mainly farmers (61%) and housewives (88%). Pallor was the reason for consultation in 29% of patients and present in 60%. On blood count, anemia was present in 92% of patients, half of whom (50%) had severe anemia with a hemoglobin level below 7 g/dL. The anemia was mainly microcytic (72%) and hypochromic (66%). Hyperleukocytosis (62%), eosinophilia (68%) and basophilia (58%) were the abnormalities observed in the white line. Thrombocytopenia accounted for 40%. Severe malaria (53%) was the main discharge diagnosis and almost all patients (99%) were alive at discharge. Conclusion: The characteristics of anemia require a study of the complete blood count in healthy children with dosage of serum iron and ferritin for a better understanding of the phenomenon.

Ten-year Etiologic Review of Chinese Children Hospitalized for Pediatric Cataracts

Purpose:Our aim was to obtain a better understanding of the etiologies and characteristics of pediatric cataracts treated at a single facility in China.Methods:.Medical records accrued over a 10-year period(from August, 2003 to July, 2013) at Shengjing Hospital of China Medical University were reviewed retrospectively,ide ntifying all patients treated for various subtypes of pediatric cataract..A database with 367 subjects under 14 years of age(598, including second-round surgeries) was generated.Results:.Of this cohort(n =367; males: 232, 63.2%; females: 135, 36.8%), 200 patients(54.5%) had bilateral cataracts,and 258(70.3%) were under 3 years of age. In all age groups and in all subtypes of pediatric cataract,.males were most commonly affected..Congenital cataract was the most prevalent subtype, accounting for 296 patients(80.7%). Most congenital cataracts were associated with other ocular or systemic abnormalities;.and in 48 patients(16.22%),.they were hereditary..Traumatic cataract was the most common subtype(85.92%) of acquired cataract. The few instances of cataracts due to steroids(n=3) or to metabolic disorders(n=2) occurred in males and involved both eyes.Conclusion: The majority of pediatric cataracts in this patient population were congenital in nature. A significant lag in ophthalmologic evaluation of Chinese infants was evident and should be addressed by educating both children and parents on risk factors for cataract development. Regular assessments are especially important in children subjected to long-term systemic steroid treatments.

Global trends and hotspots of type 2 diabetes in children and adolescents:A bibliometric study and visualization analysis

BACKGROUND Epidemiological surveys indicate an increasing incidence of type 2 diabetes mellitus(T2DM)among children and adolescents worldwide.Due to rapid disease progression,severe long-term cardiorenal complications,a lack of effective treatment strategies,and substantial socioeconomic burdens,it has become an urgent public health issue that requires management and resolution.Adolescent T2DM differs from adult T2DM.Despite a significant increase in our understanding of youth-onset T2DM over the past two decades,the related review and evidence-based content remain limited.AIM To visualize the hotspots and trends in pediatric and adolescent T2DM research and to forecast their future research themes.METHODS This study utilized the terms“children”,“adolescents”,and“type 2 diabetes”,retrieving relevant articles published between 1983 and 2023 from three citation databases within the Web of Science Core Collection(SCI,SSCI,ESCI).Utilizing CiteSpace and VoSviewer software,we analyze and visually represent the annual output of literature,countries involved,and participating institutions.This allows us to predict trends in this research field.Our analysis encompasses co-cited authors,journal overlays,citation overlays,time-zone views,keyword analysis,and reference analysis,etc.RESULTS A total of 9210 articles were included,and the annual publication volume in this field showed a steady growth trend.The United States had the highest number of publications and the highest H-index.The United States also had the most research institutions and the strongest research capacity.The global hot journals were primarily diabetes professional journals but also included journals related to nutrition,endocrinology,and metabolism.Keyword analysis showed that research related to endothelial dysfunction,exposure risk,cardiac metabolic risk,changes in gut microbiota,the impact on comorbidities and outcomes,etc.,were emerging keywords.They have maintained their popularity in this field,suggesting that these areas have garnered significant research interest in recent years.CONCLUSION Pediatric and adolescent T2DM is increasingly drawing global attention,with genes,behaviors,environmental factors,and multisystemic interventions potentially emerging as future research hot spots.

Negative efficacy of antidepressants in pharmacotherapy of child and adolescent depression

Antidepressants are the main drugs used to treat depression,but they have not been shown to be effective in the treatment of child and adolescent depression.However,many adolescent depression treatment guidelines still recommend the use of antidepressants,especially specific serotonin re-uptake inhibitors.Previous studies have suggested that antidepressants have little therapeutic effect but many side effects,such as switching to mania,suicide,and non-suicidal self injury(NSSI),in the treatment of child and adolescent depression.In the process of developing guidelines,drug recommendations should not only focus on impro-ving symptoms,but they should also consider potential side effects.This review discusses the serious side effects of antidepressants,including switching to mania,suicide,and NSSI.

Relationship between Authoritative Parenting Style and Preschool Children’s Emotion Regulation:A Moderated Mediation Model

An authoritative parenting style has been shown to promote children’s emotion regulation in European-American family studies.However,little is known about how sleep problems and the child’s sibling status in Chinese families affect this relationship.Based on family system theory,this study attempts to better understand the relationship between authoritative parenting style and emotion regulation.Mothers of preschool children in Chinese kindergartens completed questionnaires about their children’s sleep habits,their authoritative parenting styles,and children’s emotion regulation.A total of 531 children participated in this study.Results showed that authoritative parenting was positively associated with emotional regulation.Sleep problems mediated the effects of authoritative parenting style on emotion regulation.The child’s sibling status moderated the mediating effects of sleep problems in authoritative parenting and emotion regulation relationships.Specifically,the relationship between the authoritative parenting style and sleep problems was significant for only children,while birth order had no significant influence on the authoritative parenting style and sleep problems in two-child families.These findings suggest that a lowauthoritative parenting style predicts low emotion regulation through sleep problems,and this depends on the child’s sibling status,indicating that children without siblings may impair emotion regulation due to increased sleep problems.

Psychological interventions for depression in children and adolescents:A bibliometric analysis

BACKGROUND Depression has gradually become a common psychological disorder among children and adolescents.Depression in children and adolescents affects their physical and mental development.Psychotherapy is considered to be one of the main treatment options for depressed children and adolescents.However,our understanding of the global performance and progress of psychological interventions for depression in children and adolescents(PIDCA)research is limited.AIM To identify collaborative research networks in this field and explore the current research status and hotspots through bibliometrics.METHODS Articles and reviews related to PIDCA from January 2010 to April 2023 were identified from the Web of Science Core Collection database.The Charticulator website,CiteSpace and VOSviewer software were used to visualize the trends in publications and citations,the collaborative research networks(countries,institutions,and authors),and the current research status and hotspots.RESULTS Until April 16,2023,1482 publications were identified.The number of documents published each year and citations had increased rapidly in this field.The United States had the highest productivity in this field.The most prolific institution was the University of London.Pim Cuijpers was the most prolific author.In the context of research related to PIDCA,both reference co-citation analysis and keywords co-occurrence analysis identified 10 research hotspots,including thirdwave cognitive behavior therapy,short-term psychoanalytic psychotherapy,cognitive behavioral analysis system of psychotherapy,family element in psychotherapy,modular treatment,mobile-health,emotion-regulation-based transdiagnostic intervention program,dementia risk in later life,predictors of the efficacy of psychological intervention,and risks of psychological intervention.CONCLUSION This bibliometric study provides a comprehensive overview of PIDCA from 2010 to present.Psychological intervention characterized as psychological-process-focused,short,family-involved,modular,internet-based,emotionregulation-based,and personalized may benefit more young people.

Survey and clinical considerations of gender identity in lower primary school children

BACKGROUND Gender consciousness directly affects the development of gender identity,which is a continuous and lifelong process.Meanwhile,hospitalization is a part of many children's lives and has an impact on their gender development.AIM To investigate the current situation of gender identity in lower primary school children by conducting a survey of 202 hospitalized children in the lower grades and to provide a theoretical basis and foundation for the cultivation of gender identity and medical treatment of children based on the results.This study aims to inspire clinical medical staff to scientifically and reasonably arrange hospital wards for lower primary school children and pay attention to gender protection during the medical treatment process and to help children shape a unified and clear gender identity,which will enable them to better integrate into society and promote their personality development.METHODS The gender consciousness scale for elementary and middle school students was RESULTS Gender identity was already present in lower primary school children.The children's gender roles and gender equality consciousness were strong,exceeding the critical value,but their gender characteristics,gender identity,and gender ideal consciousness were weak.Children aged 6 had the weakest gender identity,and girls had significantly stronger gender identity than boys.CONCLUSION Gender identity is already present in lower primary school children,providing a basis and inspiration for the cultivation of gender identity and medical treatment of lower primary school children.Clinical medical staff should be aware of and understand these results and should scientifically and reasonably arrange hospital wards for lower primary school children.

Circulation patterns and molecular characteristics of respiratory syncytial virus among hospitalized children in Tianjin,China,before and during the COVID-19 pandemic(2017–2022)

Respiratory syncytial virus(RSV)is the main pathogen that causes hospitalization for acute lower respiratory tract infections(ALRIs)in children.With the reopening of communities and schools,the resurgence of RSV in the COVID-19 post-pandemic era has become a major concern.To understand the circulation patterns and genotype variability of RSV in Tianjin before and during the COVID-19 pandemic,a total of 19,531 nasopharyngeal aspirate samples from hospitalized children in Tianjin from July 2017 to June 2022 were evaluated.Direct immunofluorescence and polymerase chain reaction(PCR)were used for screening RSV-positive samples and subtyping,respectively.Further analysis of mutations in the second hypervariable region(HVR2)of the G gene was performed through Sanger sequencing.Our results showed that 16.46%(3215/19,531)samples were RSV positive and a delayed increase in the RSV infection rates occurred in the winter season from December 2020 to February 2021,with the average RSV-positive rate of 35.77%(519/1451).The ON1,with H258Q and H266L substitutions,and the BA9,with T290I and T312I substitutions,are dominant strains that alternately circulate every 1–2 years in Tianjin,China,from July 2017 to June 2022.In addition,novel substitutions,such as N296Y,K221T,N230K,V251A in the BA9 genotype,and L226I in the ON1 genotype,emerged during the COVID-19 pandemic.Analysis of clinical characteristics indicated no significant differences between RSV-A and RSV-B groups.This study provides a theoretical basis for clinical prevention and treatment.However,further studies are needed to explore the regulatory mechanism of host immune responses to different lineages of ON1 and BA9 in the future.
