Double burden of malnutrition and associated factors among mother-child pairs at household level in Bahir Dar City, Northwest Ethiopia: community based cross-sectional study design.

Introduction: The double burden of malnutrition refers to the simultaneous presence of under nutrition and overweight, obesity, or diet-related non-communicable diseases which might occur at the population, household, and individual level. The simultaneous presence of overweight/obese mothers with undernourished children in the same household, as well as overweight children with underweight mothers, holds particular significance. This phenomenon primarily impacts low-income and middle-income countries. The prevalence of double-burden malnutrition at the household level has increased significantly in sub-Saharan African countries. However, there is limited knowledge regarding the extent and factors associated with the double burden of malnutrition among mother-child pairs in Ethiopia. Consequently, the objective of this study was to assess the prevalence and determinants of the double burden of malnutrition among mother-child pairs at the household level in Bahir Dar City, Ethiopia. Method: In the year 2021, a community-based cross-sectional study design was employed among 702 mother-child pairs in Bahir Dar City from February 28 to March 23. A multistage sampling technique was used to identify study participants who were interviewed using an interviewer-administered questionnaire. The nutritional status of children was evaluated using WHO Anthro Software. To determine the strength of the association, multivariable logistic regression analysis was performed, and adjusted odds ratios with their respective 95% confidence intervals were computed. Results: The prevalence of the double burden of malnutrition among mother-child pairs was 14.5% (95% CI: 12.8, 15.7%}. Participants who were in the richest wealth index were 2.72 {AOR = 2.72, 95% CI 2.01, 5.63} times more odds of double burden of malnutrition than the poorest. The odds of the double burden of malnutrition among children who had high dietary diversity decreased by 63% {AOR = 0.37, 95% CI 0.22, 0.61} than low dietary diversity. Food secure households were 1.96 {AOR = 1.96, 95% CI 1.13, 3.39} times more likely to have the double burden of malnutrition than food insecure households. The odds of the double burden of malnutrition among mothers who completed college and above decreased by 74% {AOR = 0.26 95% CI 0.121, 0.549} than those unable to read and write. Conclusions and recommendation: The magnitude of the double burden of malnutrition was lower than the Ethiopian Demographic and Health Survey. Wealth index, dietary diversity, food security, and educational status were significantly associated with the double burden of malnutrition. Therefore, it is recommended to implement public health interventions that target the identified associated factors in order to reduce the burden of double malnutrition.

Characterization of the Entner-Doudoroff pathway in Pseudomonas aeruginosa catheter-associated urinary tract infections.

Pseudomonas aeruginosa is an opportunistic nosocomial pathogen responsible for a subset of catheter-associated urinary tract infections (CAUTI). In a murine model of P. aeruginosa CAUTI, we previously demonstrated that urea within urine suppresses quorum sensing and induces the Entner-Doudoroff (E-D) pathway. The E-D pathway consists of the genes zwf, pgl, edd, and eda. Zwf and Pgl convert glucose-6-phosphate into 6-phosphogluconate. Edd hydrolyzes 6-phosphogluconate to 2-keto-3-deoxy-6-phosphogluconate (KDPG). Finally, Eda cleaves KDPG to glyceraldehyde-3-phosphate and pyruvate, which enters the citric acid cycle. Here, we generated in-frame E-D mutants in the strain PA14 and assessed their growth phenotypes on chemically defined and complex media. These E-D mutants have a growth defect when grown on glucose or gluconate as the sole carbon source, which is similar to results previously reported for PAO1 mutants lacking E-D genes. RNA-sequencing following short exposure to urine revealed minimal gene regulation differences compared to the wild type. In a murine CAUTI model, virulence testing of E-D mutants revealed that two mutants lacking zwf and pgl showed minor fitness defects. Infection with the ∆pgl strain exhibited a 20% increase in host survival, and the ∆zwf strain displayed decreased colonization of the catheter and kidneys. Consequently, our findings suggest that the E-D pathway in P. aeruginosa is dispensable in this model of CAUTI. IMPORTANCE Prior studies have shown that the Entner-Doudoroff pathway is up-regulated when Pseudomonas aeruginosa is grown in urine. Pseudomonads use the Entner-Doudoroff (E-D) pathway to metabolize glucose instead of glycolysis, which led us to ask whether this pathway is required for urinary tract infection. Here, single-deletion mutants of each gene in the pathway were tested for growth on chemically defined media with single-carbon sources as well as complex media. The effect of each mutant on global gene expression in laboratory media and urine was characterized. The virulence of these mutants in a murine model of catheter-associated urinary tract infection revealed that these mutants had similar levels of colonization indicating that glucose is not the primary carbon source utilized in the urinary tract.

Mitigating physical hazards in food processing: Risk assessment and preventive strategies.

Physical contaminants in food, such as glass, metal, and plastic, can cause significant health risks and economic loss. This study explores these understudied physical hazards, aiming to provide comprehensive risk analysis and preventive solutions. Our research identified several key infiltration points in the food supply chain, including raw material sourcing and packaging stages. These hazards can be effectively mitigated by employing advanced technologies like metal detectors and optical sorting machines, along with stringent quality control measures. The findings offer valuable insights for stakeholders in the food industry, emphasizing the need for regulatory compliance and consumer education to ensure food safety.

Community-based newborn care intervention fidelity and its implementation drivers in South Wollo Zone, North-east Ethiopia.

Community-based newborn care (CBNC) has been implemented in Ethiopia across the maternal, neonatal, and child health continuum of care with the goal of lowering newborn mortality. However, neonatal mortality rate in Ethiopian is among the highest in the world. Why neonatal mortality remains high in the face of such effective interventions is the issue. As a result, the authors claim that it is unknown whether the planned intervention is carried out effectively or not. The purpose of this study was to investigate the fidelity of community-based newborn care intervention and its implementation drivers. Multicenter community-based mixed method study was employed on 898 postpartum women, 16 health extension workers (HEWs) and 10 health posts to evaluate CBNC intervention fidelity. Structured questionnaire and facility audit checklist was used to collect quantitative data. In-depth interview technique was used to explore lived experiences of HEWs on CBNC implementation. CBNC intervention fidelity was computed as a composite index of the product of program coverage, frequency and contents. Multilevel linear regression model with adjusted ß-coefficients at P-value of 0.05 and a 95% confidence interval (CI) were used to declare a significant relation between CBNC intervention fidelity and its implementation drivers. Interpretative phenomenological analysis was employed for qualitative data analysis. CBNC intervention fidelity was found to be 4.5% (95% CI: 3.6-5.4) with only two women received the intervention with full fidelity. The overall CBNC intervention coverage was 38.4% (95% CI: 35.2-41.6). Only 8.1% and 1.5% of women received all CBNC interventions with recommended frequency and content, respectively. HEWs knowledge of danger sign was significant facilitator while lack of: health center's feedback, related short-term training, health development army support, health center staff's technical assistance to HEWs and shortage of medical equipment supply were barriers for CBNC intervention fidelity. In conclusion the CBNC intervention fidelity was too low in this study. This indicates that CBNC intervention package was not implemented as envisioned implying an implementation gap. All implementation drivers were poorly implemented to result in improved fidelity and intervention outcomes.

Food consumption patterns in employees of Ethiopian institute of agricultural research.

In developing countries, including Ethiopia, diet-related non-communicable diseases are prevalent among the working population. Understanding this active group's dietary diversity and food consumption patterns is essential to devise alternative solutions and recommend possible improvements. This study investigates the food consumption patterns of employees of the Ethiopian Institute of Agricultural Research. A cross-sectional survey was conducted from January 1 to March 31, 2022, involving 13 different research centers of the institute situated in different agro-ecological regions of the country. A validated food frequency questionnaire and a 24-h food recall were administered to a total sample size of 355 employees. A systematic random sampling was used for data collection. Stata survey commands version 16.0 and multiple logistic regression were used to analyze the data. The research confirmed that socio-demographic determinants, income, and educational level affect the food consumption patterns of employees. The majority of employees have low consumption of foods like fish, fruits, vegetables, and animal products. Consumption of all kinds of animal products was very low on Wednesday and Friday. This result will help employees to give more attention to low-cost healthier food items, as well as institutional management bodies in designing awareness-creation campaigns and government programs to encourage the production and access of nutritious food.

Catheter-associated urinary tract infection by Pseudomonas aeruginosa progresses through acute and chronic phases of infection.

Healthcare-associated infections are major causes of complications that lead to extended hospital stays and significant medical costs. The use of medical devices, including catheters, increases the risk of bacterial colonization and infection through the presence of a foreign surface. Two outcomes are observed for catheterized patients: catheter-associated asymptomatic bacteriuria and catheter-associated urinary tract infection (CAUTI). However, the relationship between these two events remains unclear. To understand this relationship, we studied a murine model of Pseudomonas aeruginosa CAUTI. In this model, we also observe two outcomes in infected animals: acute symptoms that is associated with CAUTI and chronic colonization that is associated with asymptomatic bacteriuria. The timing of the acute outcome takes place in the first week of infection, whereas chronic colonization occurs in the second week of infection. We further showed that mutants lacking genes encoding type III secretion system (T3SS), T3SS effector proteins, T3SS injection pore, or T3SS transcriptional activation all fail to cause acute symptoms of CAUTI. Nonetheless, all mutants defective for T3SS colonized the catheter and bladders at levels similar to the parental strain. In contrast, through induction of the T3SS master regulator ExsA, all infected animals showed acute phenotypes with bacteremia. Our results demonstrated that the acute symptoms, which are analogous to CAUTI, and chronic colonization, which is analogous to asymptomatic bacteriuria, are independent events that require distinct bacterial virulence factors. Experimental delineation of asymptomatic bacteriuria and CAUTI informs different strategies for the treatment and intervention of device-associated infections.

Patatin-like phospholipase CapV in Escherichia coli - morphological and physiological effects of one amino acid substitution.

In rod-shaped bacteria, morphological plasticity occurs in response to stress, which blocks cell division to promote filamentation. We demonstrate here that overexpression of the patatin-like phospholipase variant CapVQ329R, but not CapV, causes pronounced sulA-independent pyridoxine-inhibited cell filamentation in the Escherichia coli K-12-derivative MG1655 associated with restriction of flagella production and swimming motility. Conserved amino acids in canonical patatin-like phospholipase A motifs, but not the nucleophilic serine, are required to mediate CapVQ329R phenotypes. Furthermore, CapVQ329R production substantially alters the lipidome and colony morphotype including rdar biofilm formation with modulation of the production of the biofilm activator CsgD, and affects additional bacterial traits such as the efficiency of phage infection and antimicrobial susceptibility. Moreover, genetically diverse commensal and pathogenic E. coli strains and Salmonella typhimurium responded with cell filamentation and modulation in colony morphotype formation to CapVQ329R expression. In conclusion, this work identifies the CapV variant CapVQ329R as a pleiotropic regulator, emphasizes a scaffold function for patatin-like phospholipases, and highlights the impact of the substitution of a single conserved amino acid for protein functionality and alteration of host physiology.

Intervention fidelity and its determinants of focused antenatal care package implementation, in south Wollo zone, Northeast Ethiopia.

BACKGROUND: Focused antenatal care is directed at sustaining maternal health and improving fetal wellbeing to ensure birth of a healthy neonate. Failure to implement focused antenatal care can result in inability to reduce maternal and perinatal morbidity and mortality in low income countries. Due to evidence-practice gaps, however, thousands of maternal, fetal and neonatal lives are still lost every day, mostly from preventable causes. This study aimed to assess focused antenatal care package's intervention fidelity and its determinant factors in South Wollo Zone, Northeast Ethiopia. METHODS: A cross-sectional study design was employed and a total of 898 women who gave birth in the last 6 months prior to data collection were included. Also 16 health extension workers, working in ten selected health posts, were included. Interviews and self-administered questionnaires were used to collect data from mothers and health extension workers. Ten [10] health posts were audited to assess availability and functionality of drugs and supplies to provide focused antenatal care. Mothers were asked whether or not the required level of care was provided. Health extension workers were provided with self-administered questionnaires to assess socio-demographic characteristics, reception of training, facilitation strategies for the implementation of focused antenatal care and ability to classify danger signs. Multilevel linear regression analysis was performed to identify individual and organizational level's factors influencing focused antenatal care package intervention fidelity. RESULTS: Overall weighted average focused antenatal care package intervention fidelity (implemented as intended/planned) was 49.8% (95% CI: 47.7-51.8), which means the average number of focused antenatal care package interventions women received is 49.8%. Health extension workers implemented 55.1% and skilled providers (nurses, midwives, health officers or medical doctors) 44.9% of focused antenatal care package interventions. Overall antenatal care coverage, irrespective of frequency (at least one visit), was 752/898 women (83.7%; 95% CI: 81.3-86.1); 263/752 women (35.0%; 95% CI: 31.6-38.4) received at least four antenatal visits and only 46/752 women (6.1%; 95% CI: 4.4-7.8) received all recommended components of focused antenatal care. Previous pregnancy-related problems, paternal education and implementation of facilitation strategies were found to be significant factors enhancing focused antenatal care package intervention fidelity. CONCLUSION: Focused antenatal care package intervention fidelity in the study area was low; this may imply that the current level of maternal, perinatal and neonatal mortality might be partly due to the low level of focused antenatal care intervention fidelity. Improving implementation of facilitation strategies is highly required to contribute to the reduction of those mortalities.

A mixed methods analysis of the magnitude and associated factors of time management practice among primary hospital employees in North Gondar, Ethiopia.

Time management contributes to work efficiency, maintaining balance, and job satisfaction by promoting productivity and success. Most people believe they have so much to do and not enough time, and they attribute their unmet expectations, poor results, and low productivity to a lack of time. The aim of this study was to determine the magnitude and associated factors of time management practice among primary hospital employees in North Gondar, Ethiopia.From March 15 to April 28, 2017, a hospital-based cross-sectional mixed methods (both quantitative and qualitative) study design was conducted in North Gondar Zone. For the quantitative part, pre-tested, standardized questionnaires; as well as an interviewer guide for the qualitative part of the study were used for data collection. Using a random sampling technique, 391 employees were completed the questionnaires. A multivariate and bi-variate logistic regression analysis at AOR with a 95% CI and a p-value of < 0.5 were used to identify significant factors of the study. For qualitative data, thematic content analysis was performed. A total of 391 participants (a response rate of 92.6%) took part in the study. The number of participants who practice time management was 56.4% (95% CI: 49.3%, 61.7%). Organizational policies (AOR: 2.16; 95% CI: 1.02, 4.68), performance appraisal systems (AOR: 2.11; 95% CI: 1.32, 4.66), compensation and benefits system (AOR: 4.18; 95% CI: 2.18, 7.99), employee planning experience (AOR: 2.86; 95% CI: 1.42, 5.75), and residence (AOR: 2.08; 95% CI: 1.08, 4.01) were found predictors of time management practice among primary hospital employees. Overall, there was a moderate level of time management practice in the study area. Significant factors found were organizational policies, compensation and benefits packages, performance appraisal systems, planning experience, and residency. Therefore, managers need to develop an intervention to address all the above factors in order to improve time management practice of primary hospital employees at work.

Cost of Hemodialysis Treatment and Associated Factors Among End-Stage Renal Disease Patients at the Tertiary Hospitals of Addis Ababa City and Amhara Region, Ethiopia.

PURPOSE: Hemodialysis is a renal replacement therapy for end-stage renal disease (ESRD) patients who consume substantial healthcare resources, which increases the economic burden. Plenty of factors affects the cost of hemodialysis treatment, particularly in resource-limited settings. Moreover, the demand for hemodialysis may decrease as the cost increases, but there is limited evidence in Ethiopia. Thus, this study aimed to estimate the cost of hemodialysis treatment among ESRD patients in the tertiary hospitals of Addis Ababa City and Amhara region, Ethiopia. PATIENTS AND METHODS: An institutional-based cross-sectional study was conducted among 172 ESRD patients undergoing hemodialysis treatment. A structured questionnaire and patients' medical chart were used to estimate the costs, and the human capital approach was applied to calculate the indirect costs. A generalized linear model (GLM) was fitted after the modified park test to identify the associated factors. In the final GLM, a p-value of <0.05 and a 95% CI were used to declare the significant variables. RESULTS: The mean annual cost of hemodialysis treatment was 121,089.27ETB ($4466.59) ± 33,244.99 ($1226.29). The direct and indirect costs covered 77.0% and 23.0% of the total costs, respectively. Age (ex(b): 1.01, p-value <0.001), highest wealth status (ex(b): 1.09, p-value: 0.008), eight (ex(b): 1.27, p-value <0.001) and 12 visits/month (ex(b): 1.34, p-value <0.001), anemia (ex(b): 1.13, p-value <0.001), and comorbidity (ex(b): 1.09, p-value: 0.039) were the factors associated with the costs of hemodialysis treatment. CONCLUSION: The annual cost of hemodialysis treatment among ESRD patients was high compared to the national per capita health expenditure, and two-thirds covered by the direct medical costs. Old age, high wealth status, more visits, anemia, and comorbidity were factors associated with the costs of hemodialysis. Therefore, the healthcare system must make a great effort for cost reduction and reduce the patients with kidney disease before they reach end-stages.

Interaction of Staphylococcus aureus and Host Cells upon Infection of Bronchial Epithelium during Different Stages of Regeneration.

The primary barrier that protects our lungs against infection by pathogens is a tightly sealed layer of epithelial cells. When the integrity of this barrier is disrupted as a consequence of chronic pulmonary diseases or viral insults, bacterial pathogens will gain access to underlying tissues. A major pathogen that can take advantage of such conditions is Staphylococcus aureus, thereby causing severe pneumonia. In this study, we investigated how S. aureus responds to different conditions of the human epithelium, especially nonpolarization and fibrogenesis during regeneration using an in vitro infection model. The infective process was monitored by quantification of the epithelial cell and bacterial populations, fluorescence microscopy, and mass spectrometry. The results uncover differences in bacterial internalization and population dynamics that correlate with the outcome of infection. Protein profiling reveals that, irrespective of the polarization state of the epithelial cells, the invading bacteria mount similar responses to adapt to the intracellular milieu. Remarkably, a bacterial adaptation that was associated with the regeneration state of the epithelial cells concerned the early upregulation of proteins controlled by the redox-responsive regulator Rex when bacteria were confronted with a polarized cell layer. This is indicative of the modulation of the bacterial cytoplasmic redox state to maintain homeostasis early during infection even before internalization. Our present observations provide a deeper insight into how S. aureus can take advantage of a breached epithelial barrier and show that infected epithelial cells have limited ability to respond adequately to staphylococcal insults.

Molecular mechanisms of probiotic prevention of antibiotic-associated diarrhea.

Antibiotic-associated diarrhea (AAD) is a common and unintended adverse effect of antibiotic treatment. It is characterized by the disruption of the gut microbiota, decreased intestinal short chain fatty acid (SCFA) concentrations, accumulation of luminal carbohydrates and colonic bile acids, altered water absorption, and ultimately diarrhea. Probiotics were shown to prevent AAD in numerous clinical trials. This review examines what is currently known about how probiotics reduce the risk for AAD via modulating the gut microbiota, altering nutrient and bile acid metabolism, inducing epithelial solute transporter activity, supporting intestinal barrier function, and influencing the immune system. Although probiotics are frequently prescribed with antibiotic use, mechanistic evidence verifying how they confer protection against AAD is extremely limited. This information is urgently needed for improving recommendations for sustaining probiotic development and for implementing probiotics in clinical settings.

Heterogeneous antimicrobial activity in broncho-alveolar aspirates from mechanically ventilated intensive care unit patients.

Pneumonia is an infection of the lungs, where the alveoli in the affected area are filled with pus and fluid. Although ventilated patients are at risk, not all ventilated patients develop pneumonia. This suggests that the sputum environment may possess antimicrobial activities. Despite the generally acknowledged importance of antimicrobial activity in protecting the human lung against infections, this has not been systematically assessed to date. Therefore, the objective of the present study was to measure antimicrobial activity in broncho-alveolar aspirate ('sputum") samples from patients in an intensive care unit (ICU) and to correlate the detected antimicrobial activity with antibiotic levels, the sputum microbiome, and the respective patients' characteristics. To this end, clinical metadata and sputum were collected from 53 mechanically ventilated ICU patients. The antimicrobial activity of sputum samples was tested against Streptococcus pneumoniae, Staphylococcus aureus and Streptococcus anginosus. Here we show that sputa collected from different patients presented a high degree of variation in antimicrobial activity, which can be partially attributed to antibiotic therapy. The sputum microbiome, although potentially capable of producing antimicrobial agents, seemed to contribute in a minor way, if any, to the antimicrobial activity of sputum. Remarkably, despite its potentially protective effect, the level of antimicrobial activity in the investigated sputa correlated inversely with patient outcome, most likely because disease severity outweighed the beneficial antimicrobial activities.

Suicidal plan, attempt, and associated factors among patients with diabetes in Felegehiwot referral hospital, Bahirdar, Ethiopia: cross-sectional study.

BACKGROUND: Diabetes is a highly prevalent non-communicable disease which is prone to more psychiatric complications like suicide; however, research into this area is limited. Assessing suicidal plan and attempt as well as its determinants are therefore important. METHOD: Institution based cross-sectional study was conducted from May 21 to June 21 at the diabetic outpatient clinic by recruiting 421 participants using systematic sampling. Suicide manual of the composite international diagnostic interview (CIDI) was used to assess suicidal plan and attempt. Chart review was used to obtain data regarding the co-morbidity of medical illness and complications of diabetes mellitus. Binary logistic regression was used to identify factors associated with suicidal attempt. Odds ratio with 95% CI was employed and variables with a p-value of< 0.05 in multivariable logistic regression were declared significant. RESULTS: From 423 participants 421 participated in the study with 99.5% response rate. The mean age (±SD) of the respondents was 38.0((±13.9) years. The lifetime prevalence of Suicidal plan; an attempt was found to be 10.7 and 7.6% respectively. Being female (AOR = 2.14, 95%CI:1.10,5.65), poor social support (AOR = 3.21,95%CI:1.26,8.98), comorbid depression (AOR = 6.40,95%CI:2.56,15.46) and poor glycemic control (AOR = 4.38,95%CI:1.66,9.59) were factors associated with lifetime suicidal attempt. CONCLUSION: The prevalence of suicidal attempt among Diabetes patients is high (7.6%). The suicidal attempt had a statistically significant association with female gender, comorbidity with depression, poor social support and poor glycemic control. Therefore the result of this study helps to do early screening, treatment, and referral of patients with suicidal attempt.

Health Extension Workers' diagnostic accuracy for common childhood illnesses in four regions of Ethiopia: a cross-sectional study.

AIM: The Ethiopian primary care of sick children is provided within the integrated Community Case Management of childhood illnesses by Health Extension Workers (HEW). There is limited knowledge whether this cadre correctly assess and classify common diseases. The aim was to study their ability to correctly classify common childhood illnesses. METHODS: A survey was conducted from December 2016 to February 2017 in four regions of Ethiopia. Observations of the HEWs' assessment and classification of sick children were followed by child re-examination by a trained health officer. RESULTS: The classification by the HEWs of 620 sick children as compared to the re-examiner had a sensitivity of 89% and specificity of 94% for diarrhoea, sensitivity 52% and specificity 91% for febrile disorders, and a sensitivity of 59% and specificity of 94% for acute respiratory tract infection. Malnutrition and ear infection had a sensitivity of 39 and 61%, and a specificity of 99 and 99%, respectively. CONCLUSION: Most cases of diarrhoea were correctly classified, while other illnesses were not frequently identified. The identification of malnutrition was especially at fault. These findings suggest that a significant number of sick children were undiagnosed that could lead to absent or incorrect management and treatment.

Metabolic Cross-talk Between Human Bronchial Epithelial Cells and Internalized Staphylococcus aureus as a Driver for Infection.

Staphylococcus aureus is infamous for causing recurrent infections of the human respiratory tract. This is a consequence of its ability to adapt to different niches, including the intracellular milieu of lung epithelial cells. To understand the dynamic interplay between epithelial cells and the intracellular pathogen, we dissected their interactions over 4 days by mass spectrometry. Additionally, we investigated the dynamics of infection through live cell imaging, immunofluorescence and electron microscopy. The results highlight a major role of often overlooked temporal changes in the bacterial and host metabolism, triggered by fierce competition over limited resources. Remarkably, replicating bacteria reside predominantly within membrane-enclosed compartments and induce apoptosis of the host within ∼24 h post infection. Surviving infected host cells carry a subpopulation of non-replicating bacteria in the cytoplasm that persists. Altogether, we conclude that, besides the production of virulence factors by bacteria, it is the way in which intracellular resources are used, and how host and intracellular bacteria subsequently adapt to each other that determines the ultimate outcome of the infectious process.

Metabolic niche adaptation of community- and hospital-associated methicillin-resistant Staphylococcus aureus.

Methicillin-resistant Staphylococcus aureus (MRSA) originally emerged in nosocomial settings and has subsequently spread into the community. In turn, community-associated (CA) MRSA lineages are nowadays introduced from the community into hospitals where they can cause hospital-associated (HA) infections. This raises the question of how the CA-MRSA lineages adapt to the hospital environment. Previous studies implicated particular virulence factors in the CA-behaviour of MRSA. However, we hypothesized that physiological changes may also impact staphylococcal epidemiology. With the aim to identify potential metabolic adaptations, we comparatively profiled the cytosolic proteomes of CA- and HA-isolates from the USA300 lineage that was originally identified as CA-MRSA. Interestingly, enzymes for gluconeogenesis, the tricarboxylic acid cycle and biosynthesis of amino acids are up-regulated in the investigated CA-MRSA isolates, while enzymes for glycolysis and the pentose phosphate pathway are up-regulated in the HA-MRSA isolates. Of note, these data apparently match with the clinical presentation of each group. These observations spark interest in central carbon metabolism as a key driver for adaptations that streamline MRSA for propagation in the community or the hospital.

Prevalence of stunting and associated factors among preschool children: A community based comparative cross sectional study in Ethiopia.

BACKGROUND: The prevalence of under nutrition is very high in developing countries especially in women and under five children. Stunting alone affected an estimated 154.8 million (22.9%) under five children globally in 2016. It is one of the main undernutrition and health problems facing children in Ethiopia. Hence, the aim of the current study was to assess the prevalence and associated factors of stunting among preschool children from food secure and food insecure households in Albuko district, northeast Ethiopia. METHODS: This study was addressed by a community based comparative cross sectional study design which was conducted among preschool children in Albuko district from March to April 2017. Simple random sampling was used to select the five representative kebeles. To reach study participants, systematic sampling technique was utilized. Pretested and structured questionnaire was used to collect data. Height measurement was collected for each child. Anthropometric indicator, height-for-age was determined for children using current WHO growth standards. Adjusted odds ratio (AOR) with its 95 % confidence interval (CI) was computed to assess the strength of the association. To identify the associated factors of stunting, multivariable logistic regression models were built. In the multivariable analysis, variables with a P-value of <0.05 were considered statistically significant. RESULTS: The overall combined prevalence of stunting among preschool children in the study area was 39.3% [95%CI; 36.3, 42.3%]. A higher stunting prevalence was observed among preschool children from food insecure households [42.8%, 95%CI; 38.4, 47.2%] than food secure ones [35.9%, 95%CI; 31.7, 40.1%]. Having uneducated mothers, large family size, and male sex were common factors significantly associated with stunting in both food secure and insecure households. While child birth order and the amount of water (<40 litters) for use were significantly associated with stunting among preschool children living in food secure households, and lesser child age, lack of extra food during pregnancy/lactation, and low dietary diversity score (DDS below four food groups) were significantly associated with stunting among preschool children from food insecure households. CONCLUSION: The present study showed that stunting is an important public health problem among preschool children from both food secure and insecure households in Albuko district. Though productive safety net program (PSNP) is a proven strategy in reducing the burden of childhood undernutrition/stunting, this study showed that there is no significant variation in the magnitude of stunting. However, it does not mean that PSNP interventions are not important in reducing the prevalence of stunting. Therefore, strengthening maternal nutrition, family planning utilization, and maternal education and enhancing dietary diversity, water sanitation and hygiene are critical interventions to reduce the level of stunting among under five children.

Prevalence of disability and associated factors in Dabat Health and Demographic Surveillance System site, northwest Ethiopia.

BACKGROUND: Despite the high burden of disability in Ethiopia, little is known about it, particularly in the study area. Hence, this study aimed to investigate the prevalence and factors associated with disability at Dabat Health and Demographic Surveillance System (HDSS) site, northwest Ethiopia. METHOD: A population-based study was conducted from October to December 2014 at Dabat HDSS site. A total of 67,395 people were included in the study. The multivariable binary logistic regression analysis was employed to identify factors associated with disability. The Adjusted Odds Ratio (AOR) with a 95% Confidence Interval (CI) was estimated to show the strength of association. A p-value of <0.05 was used to declare statistical significance. RESULTS: One thousand two hundred twenty-eight individuals were reported to have a disability giving a prevalence rate of 1.82%, of which, about 39% was related to a vision disability. The high odds of disability were observed among the elderly (≥50 years) [AOR: 4.49; 95% CI: 1.95, 10.33], severely food in-secured [AOR: 2.11; 95% CI: 1.59, 2.80], and separated marital status [AOR: 7.52; 95% CI: 1.18, 47.84]. While having a paid job [AOR: 0.46; 95% CI: 0.28, 0.77], being in the richest quintile [AOR: 0.55; 95% CI: 0.41, 0.75], and high engagement in work-related physical activities [AOR: 0.36; 95% CI: 0.27, 0.49] were inversely associated with the disability. CONCLUSION: Disability is a major public health problem, and the burden is noticeable in the study area. Vision disability is the highest of all disabilities. Thus, efforts must be made on educating the public about disability and injury prevention. Measures that reduce disability should target the elderly, the poorer and the unemployed segment of the population.
