The Association Between The Physical Condition of the House and the Smoking Habits of Residents with the Incidence of Pneumonia In Children Under Five Years

Pneumonia is leading cause of death worldwide, with a prevalence of 44%, and is second leading cause of death among under-fives in Indonesia, at 15.5%. Pneumonia is caused by viruses and bacteria that are associated with physical conditions, air quality, and smoking habits in house. This study aimed to determine association between physical house conditions and smoking habits with incidence of pneumonia in children under five years in Cengkareng Health Center working area. This study was a case-control design analytic observational study. Population involved chindren under five aged 12-59 months with a sample of 43 cases and 43 controls calculated using Lemeshow’s formula, taken using purposive sampling technique. Independent variables included floor and wall types, ventilation, occupancy density, temperature, humidity, light intensity, PM10 and PM2.5 levels, and smoking habits. Dependent varariable are incident of pneumonia. Data were collected through observation, sanitarian kits, and questionnaires. Data were analyzed using chi-square and logistic regression with 95% CI and alpha 0.05. The results showed that PM2.5 levels (p=0.010, OR=3.290, 95% CI=1.323-8.181) and indoor smoking (p=0.044, OR=2.758, 95% CI=1.027-7.410) were most significant factors associated with pneumonia. This study recommends optimizing educational programs regarding PM2.5 exposure and smoking habits to improve healthy living practices and reduce risk of pneumonia

Persistent elevation in incidence of pneumonia in children in England, 2023/24.

Since November 2023, the absolute number of attendances at emergency departments for pneumonia among children aged 5-14 years in England have been above expected levels for the time of year. This increased signal peaked during March 2024 but then persisted into early summer 2024 despite decreases in prevalence of seasonal respiratory pathogens. Record linkage between emergency department and laboratory databases points to this unusual activity being driven largely by Mycoplasma pneumoniae.

Association between indoor environmental risk factors and pneumonia among preschool children in Urumqi：A case-control study

BackgroundPediatric pneumonia presents a significant global health challenge, particularly in low- and middle-income countries. This study aimed to investigate the incidence of pneumonia in preschool children in Urumqi and its association with indoor environmental factors. MethodsThis case-control study collected data from December 2018 to December 2019 on 1522 preschool children in Urumqi (779 boys and 743 girls) who were diagnosed with pneumonia by a physician. A control group of children who had never had pneumonia was matched in a 1:1 ratio based on gender, age, and ethnicity. Using questionnaires, data were collected on children's general characteristics, passive smoking, types of housing, flooring materials, and indoor dampness, analyzing potential factors associated with the incidence of pediatric pneumonia. ResultsMultivariate analysis revealed that cesarean birth (odds ratio [OR] = 1.27; 95 % confidence interval [95%CI] = 1.08–1.48), being an only child (OR = 1.32; 95%CI = 1.13–1.55), antibiotic treatment during the first year of life (OR = 2.51; 95%CI = 1.98–3.19), passive smoking during the mother's pregnancy (OR = 1.62; 95%CI = 1.24–2.13), living in multi-family apartment housing (OR = 1.64; 95%CI = 1.28–2.10) and other types of housing (OR = 1.47; 95%CI = 1.09–1.99), laminate flooring (OR = 1.31; 95%CI = 1.01–1.72), and tile/stone/cement flooring flooring (OR = 1.31; 95%CI = 1.06–1.61), and dampness in dwelling (during first year of mother's pregnancy) (OR = 1.30; 95%CI = 1.04–1.63) were risk factors for pediatric pneumonia. The use of fresh air filtration systems in children's residences (OR = 0.66; 95%CI = 0.50–0.86) was identified as a protective factor. ConclusionThis study underscores the importance of indoor environmental factors in the prevention of pediatric pneumonia. Public health strategies should consider these factors to reduce the incidence of pneumonia in children. Future research needs to be conducted over a broader geographical range and consider a more comprehensive range of factors influencing pediatric pneumonia.

Structure-Based Virtual Screening, ADMET Properties Prediction and Molecular Dynamics Studies Reveal Potential Inhibitors of Mycoplasma pneumoniae HPrK/P.

Mycoplasma pneumoniae pneumonia (MPP) is a frequent cause of community-acquired pneumonia (CAP) in children. The incidence of childhood pneumonia caused by M. pneumoniae infection has been rapidly increasing worldwide. M. pneumoniae is naturally resistant to beta-lactam antibiotics due to its lack of a cell wall. Macrolides and related antibiotics are considered the optimal drugs for treating M. pneumoniae infection. However, clinical resistance to macrolides has become a global concern in recent years. Therefore, it is imperative to urgently identify new targets and develop new anti-M. pneumoniae drugs to treat MMP. Previous studies have shown that deficiencies in HPrK/P kinase or phosphorylase activity can seriously affect carbon metabolism, growth, morphology, and other cellular functions of M. pneumoniae. To identify potential drug development targets against M. pneumoniae, this study analyzed the sequence homology and 3D structure alignment of M. pneumoniae HPrK/P. Through sequence and structure analysis, we found that HPrK/P lacks homologous proteins in the human, while its functional motifs are highly conserved in bacteria. This renders it a promising candidate for drug development. Structure-based virtual screening was then used to discover potential inhibitors among 2614 FDA-approved drugs and 948 bioactive small molecules for M. pneumoniae HPrK/P. Finally, we identified three candidate drugs (Folic acid, Protokylol and Gluconolactone) as potential HPrK/P inhibitors through molecular docking, molecular dynamics (MDs) simulations, and ADMET predictions. These drugs offer new strategies for the treatment of MPP.

The Effect of House Environmental Factors on the Incidence of Pneumonia in Toddlers

Pneumonia is an infection of the lower respiratory tract and it is a leading cause of death in toddlers around the world, especially in developing countries including Indonesia. Environmental factors have an important role in the incidence of pneumonia. This study aimed to determine the house environmental factors that influence the incidence of pneumonia in children &lt; 60 months in the working area of Public Health Center P. This study used a cross-sectional design that involved 114 children (aged &lt; 60 months) with their mothers. We conducted interviews and observations, and filled in the 9 checklists of the house environment: floor type, wall type, ventilation, density, cooking fuel, smoking habit, humidity, light intensity, and temperature. The data were analyzed with the Chi-square test and logistic regression. The results showed that the factors of the house enviroment affecting pneumonia in children &lt; 60 months were light intensity (p = 0.001; OR = 5.032; 95% CI = 1.94, 13.046), humidity (p = 0.003; OR = 6.98; 95% CI = 1.91, 25.421) and density (p = 0.019; OR = 3.140; 95% CI = 1.21, 8.154). Preventive programs from health workers are very important (i.e., counseling and health education). Support from local government and the community is necessary to promote healthy households.&#x0D; Keywords: pneumonia, children &lt; 60 months, house environment

Comparing the incidence of pneumonia in children seen at a Nigerian Teaching Hospital before and during the COVID -19 pandemic

Background: Following the outbreak of the new coronavirus (COVID 19) worldwide, many governments across the world including the Nigerian government had to implement measures to curtail the spread of this virus. Such measures included social distancing and personal hygiene which could have also helped to reduce the transmission of pneumonia among other infectious diseases.&#x0D; Objective: To assess the effect of COVID-19 on the incidence of pneumonia in children seen at the Department of Pediatrics, of a Nigerian private University Teaching Hospital.&#x0D; Method: We retrospectively analyzed the data of the patients seen with pneumonia in all the Pediatric units of the Teaching Hospital from April 2019 to March 2020 (pre-pandemic period) and compared it with that of those seen during the COVID-19 pandemic from April 2020 to March 2021.&#x0D; Result: There was a 28% decrease in the total number of children seen in the department from 5,657 in pre-pandemic period to 4,079 in the pandemic period. There was a 17% decrease in the mean number of children seen with pneumonia monthly from 4.92 to 4.08 in the pandemic period. This is despite the relative increase in the incidence rate of pneumonia in children seen from 1.04% in the prepandemic period to 1.2% in the pandemic period. We noted more complications of pneumonia including heart failure and anaemia in the pandemic period (24.5% of cases) than in the pre-pandemic period (15.3% of cases).&#x0D; Conclusion: The incidence of pneumonia in children seems to have increased in the wake of the COVID 19 pandemic.

Influencing Factors and Coping Strategies of Hospitalization in Children with Leukemia Complicated with Pneumonia.

Objective To investigate the influencing factors of pneumonia when pediatric leukemia patients are hospitalized and propose coping strategies. Methods A retrospective study and analysis of the inpatient medical records of 183 children with leukemia in our hospital from August 2017 to August 2020. A total of 93 cases were in the case group of children with pneumonia, and the rest were 90 cases in the control group. Case data from two groups of children were compared, and the monofactor analysis of pneumonia occurred. The P < 0.05 was selected for its multivariate logistic regression analysis, and its coping strategy was proposed. Results After multivariate logistic retrospective analysis, it was found that the main influencing factors were neutrophils, white blood cells, vitamin D, and cellular immunity (P < 0.05). A review of the two sets of pathological data found that high doses of cytarabine reduced the incidence of pneumonia in children with leukemia (P < 0.05). Conclusion A timely understanding of the influencing factors of pediatric diabetes mellitus and pneumonia and the early application of cytarabine can reduce the incidence of pneumonia during the child's hospitalization.

Bagaimana Menurunkan Risiko Pneumonia Komunitas pada Anak-Anak Berusia &lt;5 Tahun yang Tinggal di Hunian Padat?

Overcrowding is one of the factors that contribute to respiratory diseases transmission, including pneumonia. Pneumonia is an infectious disease commonly found and is the most important cause of death for children aged &amp;lt;5. Generally, pneumonia was found in low-income residents from houses overcrowded. This study aims to identify the most dominant risk factors for community pneumonia in children aged &amp;lt;5 years who live in crowded housing in the Work Area of the North Larangan Public Health Center, Tangerang. A case-control study was conducted, with a ratio of cases and controls of 1:1, namely 25 cases and 25 controls. The sampling technique of cases is total sampling, and the control is purposive sampling. This study used univariate, bivariate with chi-square test, and regression logistic for multivariate analysis. Multivariate analysis showed that the risk factors associated with the incidence of pneumonia in children under five who lived in dense housing were exclusive breastfeeding (OR=7.65 (95% CI:1.27-46.07)) and nutritional status (OR=8.79 (95%CI:1.05-73.78)). Reducing the lack of exclusive breastfeeding and improving the underweight dietary status of children can minimize the risk of pneumonia in children under five living in dense housing.
