Perception of affordable diet is associated with pre-school children's diet diversity in Addis Ababa, Ethiopia: the EAT Addis survey.

BACKGROUND: Despite improvements in food access and nutrition security over the last few decades, malnutrition remains a major public health problem. One of the significant contributors to these problems is affordability of nutritious food. This study aimed to examine the association between perceived food affordability and pre-school children's diet diversity in Addis Ababa, Ethiopia. METHODS: Cross-sectional data from 2017 to 18 were used for the analysis. A 24-hour dietary recall assessment was done to assess children's dietary diversity (DD). We used a modified operational definition of affordability indicator called perceived affordability of dietary diversity (afford-DD) to evaluate the impact of the food environment in terms of affordability at the household level. A sample (n 4,898) of children aged 6-59 months representative of households in Addis Ababa was randomly selected using a multistage sampling procedure including all districts in the city. Mixed-effects linear regression models were used to assess the association between children's DD and afford-DD. RESULTS: The survey revealed that the mean (standard deviation [SD]) of children's DD was 3.9 [± 1.4] while the mean [SD] of afford-DD was 4.6 [± 2.1]. Overall, 59.8% of children met the minimum dietary diversity (≥ 4 food groups). White roots and tubers were the most commonly consumed food groups regardless of their affordability. Considerable variations were observed between households that reported the food item affordable and not affordable in consumption of Vitamin A rich vegetables and fruits, meat and fish, egg, and dairy. The children's DD was positively associated with afford-DD after adjusting for maternal education, household wealth status and other relevant confounding. Higher maternal education modified the association between affordability and children's diet diversity. CONCLUSIONS: This study suggests higher perceived food affordability was associated with better diet diversity in children. A higher level of maternal education had the potential to mitigate affordability challenges in meeting the children's dietary diversity needs. Our study emphasizes the need for inclusive food programs and nutrition interventions addressing social differences, intensifying efforts to make nutrient-rich diets affordable for the less privileged, and highlights the potential benefits of targeting maternal education in addressing child dietary diversity.

MARCH2, a Novel Oncogene-regulated SNAIL E3 Ligase, Suppresses Triple-negative Breast Cancer Metastases.

Epithelial-mesenchymal transition (EMT) in cancer promotes metastasis and chemotherapy resistance. A subset of triple-negative breast cancer (TNBC) exhibits a mesenchymal gene signature that is associated with poor patient outcomes. We previously identified PTK6 tyrosine kinase as an oncogenic driver of EMT in a subset of TNBC. PTK6 induces EMT by stabilizing SNAIL, a key EMT-initiating transcriptional factor. Inhibition of PTK6 activity reverses mesenchymal features of TNBC cells and suppresses their metastases by promoting SNAIL degradation via a novel mechanism. In the current study, we identify membrane-associated RING-CH2 (MARCH2) as a novel PTK6-regulated E3 ligase that promotes the ubiquitination and degradation of SNAIL protein. The MARCH2 RING domain is critical for SNAIL ubiquitination and subsequent degradation. PTK6 inhibition promotes the interaction of MARCH2 with SNAIL. Overexpression of MARCH2 exhibits tumor suppressive properties and phenocopies the effects of SNAIL downregulation and PTK6 inhibition in TNBC cells, such as inhibition of migration, anoikis resistance, and metastasis. Consistent with this, higher levels of MARCH2 expression in breast and other cancers are associated with better prognosis. We have identified MARCH2 as a novel SNAIL E3 ligase that regulates EMT and metastases of mesenchymal TNBC. SIGNIFICANCE: EMT is a process directly linked to drug resistance and metastasis of cancer cells. We identified MARCH2 as a novel regulator of SNAIL, a key EMT driver, that promotes SNAIL ubiquitination and degradation in TNBC cells. MARCH2 is oncogene regulated and inhibits growth and metastasis of TNBC. These insights could contribute to novel strategies to therapeutically target TNBC.

Feasibility and impact of school-based nutrition education interventions on the diets of adolescent girls in Ethiopia: a non-masked, cluster-randomised, controlled trial.

BACKGROUND: Adolescence is a critical period of physical and psychological development, especially for girls, because poor nutrition can affect their wellbeing as well as that of their children. We aimed to assess the feasibility and impact of a package of nutrition education interventions delivered through public primary schools on the diets of adolescent girls in Ethiopia. METHODS: In this non-masked, cluster-randomised, controlled trial, primary schools (clusters) in the Southern Nations, Nationalities, and People's Region and Somali region of Ethiopia were randomly allocated to the intervention group (nutrition information provided during flag ceremonies, classroom lessons, school club meetings, peer group mentoring, BMI measurement and counselling, and parent-teacher meetings) or the control group (standard academic curriculum on health and nutrition) by use of computer-generated pseudo-random numbers. Duration of the school-based interventions was 4 months, and the key messages were related to dietary diversity (eating a variety of foods), energy adequacy (eating breakfast and healthy snacks), and healthy food choices (avoiding junk foods). Adolescent girls were eligible for participation if aged 10-14 years and enrolled in grades 4-8 in a study school. Data were collected with two independent cross-sectional surveys: baseline before the start of implementation and endline 1·5 years later. The primary outcome of impact was dietary diversity score, defined as the number of food groups (out of ten) consumed over the previous 24 h using a list-based method, and minimum dietary diversity, defined as the proportion of girls who consumed foods from at least five of the ten food groups, in the intention-to-treat population. We also assessed intervention exposure as a measure of feasibility. We estimated intervention effects using linear regression models for mean differences at endline, with SEs clustered at the school level, and controlled for adolescent age, region, household food security, and wealth. The trial is registered with ClinicalTrials.Gov, NCT04121559, and is complete. FINDINGS: 27 primary schools were randomly allocated to the intervention group and 27 to the control group. Between March 22 and April 29, 2021, 536 adolescent girls participated in the endline survey (270 in the intervention group and 266 in the control group), with median age of 13·3 years (IQR 12·1-14·0). At endline, the dietary diversity score was 5·37 (SD 1·66) food groups in the intervention group and 3·98 (1·43) food groups in the control group (adjusted mean difference 1·33, 95% CI 0·90-1·75, p<0·0001). Increased minimum dietary diversity was also associated with the intervention (182 [67%] of 270 in the intervention group vs 76 [29%] of 266 in the control group; adjusted odds ratio 5·37 [95% CI 3·04-9·50], p<0·0001). 256 (95%) of 270 adolescent girls in the intervention group were exposed to at least one of the five in-school intervention components. INTERPRETATION: Integrating nutrition interventions into primary schools in Ethiopia was feasible and increased dietary diversity incrementally among adolescent girls, but could be limited in changing other food choice behaviours, such as junk food consumption, based on nutrition education alone.

Fathers' experiences of childcare and feeding: A photo-elicitation study in a low resource setting in urban Addis Ababa, Ethiopia.

Children's health and wellbeing studies focus mainly on mothers' roles while very little is known about the experiences/challenges that fathers face in fulfilling their responsibilities. Therefore, this study aims to explore the fathers' lived experiences of childcare and feeding in an urban low-income setting. This qualitative study was conducted in Addis Ababa, Ethiopia. Photo-elicitation was used to facilitate the in-depth interviews with fathers of children below the age of five years. All interviews were audio-recorded, transcribed and translated verbatim, followed by a thematic analysis approach. The overarching theme of this study was "Fatherhood as an enduring identity", which comprised of three sub-themes: 1) Blessings of fatherhood, 2) Adjusting to fathering roles, and 3) Struggles/demands of fatherhood in a low-resource setting. Fathers expressed that having children or becoming parents was a blessing. They expressed their love, devotion, and attachment to their children. Some used the term "my second chance in life" underscoring the importance. Although fathers strived relentlessly to spend time and care for their children, they faced challenges such as internal struggles adjusting to and fatherhood whilst maintaining a sense of their former self. As well, providing for their families amidst added pressures imposed by the external environment, such as poor housing conditions, a lack of employment opportunities, the then COVID-19 pandemic, further increased their stressors. Most fathers were engaged in child care and feeding, suggesting that like mothers, fathers should be viewed as potential agents for implementing nutrition interventions in this setting. However, if interventions are to be successful, they need to incorporate components that boost fathers' livelihoods and general wellbeing.

COVID-19 Disruptions of Food Systems and Nutrition Services in Ethiopia: Evidence of the Impacts and Policy Responses.

Background: Since its first case of COVID-19 on March 13, 2020, Ethiopia has exerted efforts to curb the spread of SARS-CoV-2 (COVID-19) without imposing a nationwide lockdown. Globally, COVID-19 related disruptions and mitigation measures have impacted livelihoods and food systems, nutrition, as well as access and use of health services. Objective: To develop a comprehensive understanding of the impacts of the COVID-19 pandemic on food systems, health services, and maternal and child nutrition and to synthesize lessons from policy responses to the COVID-19 pandemic in Ethiopia. Methods: We conducted a review of literature and 8 key informant interviews across government agencies, donors, and non-governmental organizations (NGOs), to map the impacts of the COVID-19 pandemic on the food and health systems in Ethiopia. We summarized policy responses and identified recommendations for future actions related to the COVID-19 pandemic and other future emergencies. Results: The impacts of the COVID-19 pandemic were felt across the food system and include limited agriculture inputs due to travel restrictions and closed borders restricting trade, reduced in-person support by agriculture extension workers, income losses, increases in food prices, and the reduction in food security and dietary diversity. Maternal and child health services were disrupted due to fear of contacting COVID-19, diversion of resources, and lack of personal protective equipment. Disruptions eased over time due to the expansion of social protection through the Productive Safety Net Program, and the increased outreach and home service provision by the health extension workers. Conclusion: Ethiopia experienced disruptions to food systems and maternal and child nutrition services due to the COVID-19 pandemic. However, by expanding existing social protection programs and public health infrastructure and leveraging partnerships with non-state actors, the extent of the impact of the pandemic was largely minimized. Nevertheless, vulnerabilities and gaps remain and there is a need for a long-term strategy that considers the potential for future pandemics and other shocks.

Long-term outcomes of modern multidisciplinary management of sinonasal cancers: The M. D. Anderson experience.

PURPOSE: To report long-term outcomes of modern radiotherapy for sinonasal cancers. METHODS AND MATERIALS: A retrospective analysis of patients with sinonasal tumors treated with intensity-modulated radiotherapy or proton therapy. Multivariate analysis was used to determine predictive variables of progression free survival (PFS) and overall survival (OS). RESULTS: Three hundred and eleven patients were included, with median follow-up of 75 months. The most common histologies were squamous cell (42%), adenoid cystic (15%), and sinonasal undifferentiated carcinoma (15%). Induction chemotherapy was administered to 47% of patients; 68% had adjuvant radiotherapy. Ten-year local control, regional control, distant metastasis free survival, PFS, and overall survival rates were 73%, 88%, 47%, 32%, and 51%, respectively. Age, non-nasal cavity tumor site, T3-4 stage, neck dissection, and radiation dose were predictive of PFS, while age, non-nasal cavity tumor site, T3-4 stage, positive margins, neck dissection, and use of neoadjuvant chemotherapy were predictive of OS. There was a 13% rate of late grade ≥3 toxicities. CONCLUSION: This cohort of patients with sinonasal cancer treated with modern radiotherapy demonstrates favorable disease control rate and acceptable toxicity profile.

Burden and contributing factors to overweight and obesity in young adolescents in Addis Ababa, Ethiopia.

The prevalence of overweight/obesity in adolescents has increased globally, including in low- and middle-income countries. Early adolescence provides an opportunity to develop and encourage positive health and behavioural practices, yet it is an understudied age group with limited information to guide and inform appropriate interventions. This study aims to determine the prevalence of overweight/obesity in young adolescents, aged between 10 and 14 years attending public schools in Addis Ababa, Ethiopia, and to explore the contributing factors. A cross-sectional school-based study was conducted. Adolescents completed individual questionnaires. Weight (kg) and height (m) measurements were converted to BMI-for-age and gender z-scores. Multivariate regression analysis was conducted to determine the associated factors. The overall prevalence of overweight/obesity was 8% among adolescents aged 10-14 years and it was significantly higher in females (13%) than males (2%). The diet quality for the majority of the adolescents was inadequate, putting them at risk for poor health outcomes. The contributors to overweight/obesity were different between males and females. Age and no access to a flush toilet were negatively associated with overweight/obesity in males and access to a computer, laptop or tablet was positively associated. In females, menarche was positively associated with overweight/obesity. Living with only their mother or another female adult and an increase in physical activity were negatively associated with overweight/obesity. There is a need to improve the diet quality of young adolescents in Ethiopia and understand the reasons why females are less physically active to limit the risk of poor diet-related health outcomes.

Tracking antimalarial drug resistance using mosquito blood meals: a cross-sectional study.

BACKGROUND: Strong surveillance systems with wide geographic coverage are needed to detect and respond to reports of antimalarial drug resistance on the African continent. We aimed to assess the utility and feasibility of using blood-fed mosquitos (xenomonitoring) to conduct rapid surveillance of molecular markers associated with resistance in human populations. METHODS: We conducted three cross-sectional surveys in two rainy seasons and the interim dry season in southwest Burkina Faso between Oct 10, 2018, and Sept 17, 2019. We collected human blood samples and blood-fed mosquitos residing in household clusters across seven village sectors. Samples were assessed for Plasmodium falciparum with ultrasensitive quantitative PCR, genotyped for two markers of reduced drug susceptibility, pfmdr1 256A>T (Asn86Tyr) and pfcrt 227A>C (Lys76Thr), and sequenced for four markers of clonality. We assessed statistical equivalence using a 10% margin of equivalence. FINDINGS: We identified 551 infections in 1483 human blood samples (mean multiplicity of infection [MOI] 1·94, SD 1·47) and 346 infections in 2151 mosquito blood meals (mean MOI 2·2, SD 1·67). The frequency of pfmdr1 Asn86Tyr was 4% in survey 1, 2% in survey 2, and 12% in survey 3 in human samples, and 3% in survey 1, 0% in survey 2, and 8% in survey 3 in mosquito blood meals, and inter-host frequencies were statistically equivalent in surveys 1 and 2 (p<0·0001) but not Survey 3 (p=0·062) within a tolerability of 0·10. The frequency of pfcrt Lys76Thr was 16% in survey 1, 55% in survey 2, and 11% in survey 3 in humans and 40% in survey 1, 72% in survey 2, and 13% in survey 3 in mosquitos, and inter-host frequencies were equivalent in survey 3 only (p=0·032) within a tolerability of 0·10. In simulations, multiple but not preferential feeding behaviour in mosquitos reduced the accuracy of frequency estimates between hosts, particularly for markers circulating at higher frequencies. INTERPRETATION: Molecular markers in mosquito blood meals and in humans exhibited similar temporal trends but frequencies were not statistically equivalent in all scenarios. More work is needed to determine empirical and pragmatic thresholds of difference. Xenomonitoring might be an efficient tool to provide rapid information on emerging antimalarial resistance in regions with insufficient surveillance.

Food environment around schools and adolescent consumption of unhealthy foods in Addis Ababa, Ethiopia.

Adolescent diets may be influenced by the retail food environment around schools. However, international research to examine associations between the proximity of retail food outlets to schools and diet provides equivocal support for an association. This study aims to understand the school food environment and drivers for adolescents' consumption of unhealthy foods in Addis Ababa, Ethiopia. Mixed-methods research was conducted, 1200 adolescents (10-14 years) from randomly selected government schools were surveyed, along with vendors within 5-min' walk of the schools and focus group discussions (FGDs) with adolescent groups. Mixed-effect logistic regression investigated the relationship between the number of vendors around the schools and the consumption of selected unhealthy foods. Thematic analysis was used to summarize findings from the FGDs. Consumption of sweets and sugar-sweetened beverages (S-SSB) and deep-fried foods (DFF) at least once a week was reported by 78.6% and 54.3% of the adolescents, respectively. Although all schools were surrounded by food vendors selling DFF and S-SSB, consumption was not associated with the number of vendors available around the school. However, adolescents' awareness and perception of healthy food, and their concerns about the safety of foods in the market, influenced their dietary choices and behaviours. Lack of financial resources to purchase food as desired also played a role in their selection of food and eating habits. Reported unhealthy food consumption is high among adolescents in Addis Ababa. Thus, further research is warranted to come up with school-based interventions that promote access and healthy food choices among adolescents.

Integrating private health facilities in government-led health systems: a case study of the public-private mix approach in Ethiopia.

BACKGROUND: Private health care facilities working in partnership with the public health sector is one option to create sustainable health systems and ensure health and well-being for all in low-income countries. As the second-most populous country in Africa with a rapidly growing economy, demand for health services in Ethiopia is increasing and one-quarter of its health facilities are privately owned. The Private Health Sector Program (PHSP), funded by the United States Agency for International Development, implemented a series of public-private partnership in health projects from 2004 to 2020 to address several public health priorities, including tuberculosis, malaria, HIV/AIDS, and family planning. We assessed PHSP's performance in leadership and governance, access to medicines, health management information systems, human resources, service provision, and finance. METHODS: The World Health Organization's health systems strengthening framework, which is organized around six health system building blocks, guided the assessment. We conducted 50 key informant interviews and a health facility assessment at 106 private health facilities supported by the PHSP to evaluate its performance. RESULTS: All six building blocks were addressed by the program and key informants shared that several policy and strategic changes were conducive to supporting the functioning of private health facilities. The provision of free medicines from the public pharmaceutical logistics system, relaxation of strict regulatory policies that restricted service provision through the private sector, training of private providers, and public-private mix guidelines developed for tuberculosis, malaria, and reproductive, maternal, newborn, child, and adolescent health helped increase the use of services at health facilities. CONCLUSIONS: Some challenges and threats to sustainability remain, including fragile partnerships between public and private bodies, resource constraints, mistrust between the public and private sectors, limited incentives for the private sector, and oversight of the quality of services. To continue with gains in the policy environment, service accessibility, and other aspects of the health system, the government and international communities must work collaboratively to address public-private partnerships in health areas that can be strengthened. Future efforts should emphasize a mechanism to ensure that the private sector is capable, incentivized, and supervised to deliver continuous, high-quality and equitable services.

DYNAMICS OF FIBROTIC CHANGES IN THE LIVER AFTER THE SUCCESSFUL ERADICATION OF HEPATITIS C VIRUS IN PATIENTS WITH NAFLD.

OBJECTIVE: The aim: To assess the dynamics of serum levels of angiopoietin-2 and transforming growth factor-ß1 in patients with chronic hepatitis C (CHC) with concomitant nonalcoholic fatty liver disease (NAFLD) after successful DAAs. PATIENTS AND METHODS: Materials and methods: 82 patients with CHC were examined, of which 56 were diagnosed with NAFLD and increased body weight. Ang-2, TGF-ß1, leptin, adiponectin, and the degree of liver fibrosis were determined for all participants. The patients were divided into groups: 1 gr. (n=23) - CHС + increased body weight + hepatic steatosis, 2 gr. (n=33) - СНС + increased body weight + nonalcoholic steatohepatitis, 3rd gr. (n=26) - CHC. All patients received DAAs for 12 weeks. RESULTS: Results: From 82 patients F3-4 had 31 people, F1-2 - 25, F0-1 - 11, F0 -15 patients. F3-4 and steatosis S2-3 (p<0.05) was more common in patients of 2 gr.. Serum Ang-2 levels were higher (p<0.05) in patients of 2 gr. with F3-4, than in patients with F0-2. Fibrosis regression occurred more often in patients with 1 and 3 gr. with F1-2 than in patients 2 gr. and F3-4 and was accompanied by a decrease in Ang-2 and TGF-ß1 levels. CONCLUSION: Conclusions: High levels of Ang-2 and TGF-ß1 are registered in patients with CHC+NAFLD, which correlate with the degree of liver fibrosis and significantly decrease after successful DAAs in patients with low initial stages of liver fibrosis and normal body weight.

THE CLINICAL EXPERIENCE OF THE EFFECTIVE USE OF DAPAGLIFLOZIN IN COMORBID CARDIAC PATIENTS WITH CONCOMITANT TYPE 2 DIABETES MELLITUS AND ARTERIAL HYPERTENSION ON THE BACKGROUND OF OVERWEIGHT IN OUTPATIENT SETTING.

OBJECTIVE: The aim: To assess the efficacy and safety of dapagliflozin in the treatment of comorbid cardiac patients with type 2 diabetes mellitus (T2DM) in combination with arterial hypertension (AH) and overweight in outpatient setting. PATIENTS AND METHODS: Materials and methods: Under observation were 19 patients who were treated in outpatient setting during 2019-2021 for AH and had T2DM, overweight or obesity. As part of complex treatment, patients received dapagliflozin 10 mg once a day for 12 months. RESULTS: Results: The normalization of blood pressure, elimination of heart failure symptoms on the background of increased ejection fraction, improved indicators of the functional capacity of the kidneys, and a decrease in the degree of proteinuria/albuminuria were noted after treatment. The patients had an easier time losing weight (body mass index and waist circumference decreased; p<0.05) and decreased levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C). None of the monitored patients had cases of hypoglycemia or urinary tract infection. The number and/or doses of antihypertensive, hypouricemic and diuretic drugs were gradually reduced. CONCLUSION: Conclusions: Using dapagliflozin in a standard dose of 10 mg/day in the complex therapy of patients with T2DM in combination with arterial hypertension and overweight contributes not only to the normalization of blood pressure, but also to a reduction in body weight and waist circumference. The proposed therapy can be an alternative for the treatment of patients with T2DM with concomitant overweight or obesity, arterial hypertension, with or without heart and/or renal failure as a first-line antidiabetic drug.

CDK4: a master regulator of the cell cycle and its role in cancer.

The cell cycle is regulated in part by cyclins and their associated serine/threonine cyclin-dependent kinases, or CDKs. CDK4, in conjunction with the D-type cyclins, mediates progression through the G1 phase when the cell prepares to initiate DNA synthesis. Although Cdk4-null mutant mice are viable and cell proliferation is not significantly affected in vitro due to compensatory roles played by other CDKs, this gene plays a key role in mammalian development and cancer. This review discusses the role that CDK4 plays in cell cycle control, normal development and tumorigenesis as well as the current status and utility of approved small molecule CDK4/6 inhibitors that are currently being used as cancer therapeutics.

COVID-19 disruptions of food systems and nutrition services in Ethiopia: Evidence of the impacts and policy responses

BackgroundSince its first case of COVID-19 on March 13, 2020 and Ethiopia has exerted efforts to curb the spread of the Coronavirus disease 2019 (COVID-19) without imposing a nationwide lockdown. Globally, COVID-19 related disruptions and mitigation measures have impacted livelihoods and food systems, nutrition, as well as access and use of health services.

ResultsThe impacts of the COVID-19 pandemic were felt across the food system. Disruptions were noted in inputs supply due to travel restrictions and closed borders restricting trade, reduced in-person support by agriculture extension workers, income losses, increases in food prices, and the reduction in food security and consumption of less diverse diets. Maternal and child health services were disrupted due to fear of contacting COVID-19, diversion of resources, and lack of personal protective equipment. Disruptions eased over time due to the expansion of social protection, through the Productive Safety Net Program, and the increased outreach and home service provision by the health extension workers. ConclusionEthiopia experienced disruptions to food systems and expanded existing social protection and public health infrastructure and leveraged partnerships with non-state actors. Nevertheless, vulnerabilities and gaps remain and there is a need for a long-term strategy that considers the cyclical nature of COVID-19 cases.

Parasitological, Molecular, and Epidemiological Investigation of Cryptosporidium Infection Among Cattle and Buffalo Calves From Assiut Governorate, Upper Egypt: Current Status and Zoonotic Implications.

Details about the epidemiological patterns and real contributions of different reservoir animals in maintaining the transmission cycle of Cryptosporidium spp. in Upper Egypt remain lacking. This study was designed to investigate the occurrence of Cryptosporidium spp. in cattle and buffalo (n = 608) from Upper Egypt. The parasite for the resulting positive samples by fecal examination was molecularly identified using nested PCR targeting the small subunit rRNA. Moreover, several explanatory variables, including animals' age, sex, condition, seasonal variations, were examined to describe the epidemiological pattern of the disease. Interestingly, the fecal examination revealed that 33.55% (204/608) of the animals under study were infected with Cryptosporidium, including 38.27% among cattle and 28.16% among buffalo. The parasite was molecularly identified using nested PCR, and their amplicons were identified in almost all fecal samples using microscopy (202/204). According to age as an individual variable factor, the infection rates of Cryptosporidium spp. in cattle calves with ages of <1, 1-3, and >3 months were 39.13, 34.04, and 54.54%, respectively. Meanwhile, in buffalo calves, the occurrence rates were 28.57, 27.27, and 29.41%, respectively. Regarding sex, female cattle calves were more susceptible to Cryptosporidium infection (51.28%) than males (26.19%) (p < 0.05), whereas male buffalo calves had a higher infection rate (32.25%) than females (25%). According to seasonal variations, the infection rates of Cryptosporidium spp. in cattle calves during spring, summer, autumn, and winter were 42.11, 30.43, 30, and 52.63%, respectively. In contrast, lower infection rates of 30, 21.42, 23.52, and 35% were reported in buffalo calves during spring, summer, autumn, and winter, respectively. The rate of infection was 45.16% in diarrheic cattle calves and 15.78% in non-diarrheic ones (p < 0.05). Meanwhile, the infection rate was 33.96% in diarrheic buffalo calves and 11.11% in non-diarrheic ones (p < 0.05). This study reported a higher occurrence of Cryptosporidium infection among the animals under study and revealed that buffalos and cattle can contribute to maintaining the transmission cycle of this zoonotic parasite in Upper Egypt.

Evaluation of Pleotropic Protective Activity of Capparis spinose Extract on Arthritis Rat Model.

BACKGROUND: Capparis spinosa grows in Asian and Mediterranean desert areas. Different parts of Capparis spinosa, including flowers, have been used in various folk medicine applications. OBJECTIVE: This study aims to evaluate the anti-arthritic potential of ethanolic extract of Egyptian Capparis spinosa flowers in a rat model of rheumatoid arthritis. Moreover, analysis of Capparis spinosa extract was performed using LC-qTOF-MS/MS. METHODS: Animals were split into six groups: negative control group, induced arthritic animals, arthritic rats receiving 7, 14 and 28 mg/kg of Capparis spinosa extract, respectively, in three groups to detect the optimum dose, and the induced group receiving a standard drug. The arthritic score was checked daily for 15 days after induction. After animals were sacrificed, their joints and muscles were subjected to microscopic and ultra-structure examinations. Ex vivo culturing of osteoclasts was performed. Cytokine levels were measured in all examined groups. RESULTS: The results revealed 7 mg/kg of Capparis spinosa extract as the optimal dose, which decreased inflammation signs through controlling chondrocytes, osteoclasts, and levels of inflammatory mediators. CONCLUSION: LC-Mass analysis revealed Capparis spinosa extract to contain a mixture of flavonol glycosides, flavan-3-ols and hydroxycinnamic acid derivatives, which may provide beneficial multifunction in regulating arthritic symptoms.

Residential Food Environment, Household Wealth and Maternal Education Association to Preschoolers' Consumption of Plant-Based Vitamin A-Rich Foods: The EAT Addis Survey in Addis Ababa.

Vitamin A deficiency is common among preschoolers in low-income settings and a serious public health concern due to its association to increased morbidity and mortality. The limited consumption of vitamin A-rich food is contributing to the problem. Many factors may influence children's diet, including residential food environment, household wealth, and maternal education. However, very few studies in low-income settings have examined the relationship of these factors to children's diet together. This study aimed to assess the importance of residential food availability of three plant-based groups of vitamin A-rich foods, household wealth, and maternal education for preschoolers' consumption of plant-based vitamin A-rich foods in Addis Ababa. A multistage sampling procedure was used to enroll 5467 households with under-five children and 233 residential food environments with 2568 vendors. Data were analyzed using a multilevel binary logistic regression model. Overall, 36% (95% CI: 34.26, 36.95) of the study children reportedly consumed at least one plant-based vitamin A-rich food group in the 24-h dietary recall period. The odds of consuming any plant-based vitamin A-rich food were significantly higher among children whose mothers had a higher education level (AOR: 2.55; 95% CI: 2.01, 3.25), those living in the highest wealth quintile households (AOR: 2.37; 95% CI: 1.92, 2.93), and in residentials where vitamin A-rich fruits were available (AOR: 1.20; 95% CI: 1.02, 1.41). Further research in residential food environment is necessary to understand the purchasing habits, affordability, and desirability of plant-based vitamin A-rich foods to widen strategic options to improve its consumption among preschoolers in low-income and low-education communities.

Incidence of Glaucoma Progression and Rate of Visual Field Deterioration in a Cohort of Urban Ghanaians.

PRCIS: The annual incidence of glaucoma progression (9.7%) and rates of visual field mean deviation (MD) change in progressors (-1.02±0.06 dB/y) are high in a small cohort of urban Ghanaians. PURPOSE: To report the incidence of glaucoma progression and the rate of visual field deterioration in a small cohort of Ghanaians. METHODS: One hundred ten subjects (204 eyes) diagnosed with glaucoma at a baseline population-based screening examination were re-examined a mean of 8.3±0.8 years later. Eyes were classified as having progressed if the optic disc alone, visual field alone or both showed significant glaucomatous changes on follow-up. Visual field MD was used to calculate the rate of visual field progression. RESULTS: Progression was observed in 89 (80.9%, 9.7%/year) subjects (130 eyes). Progression occurred in 32 (31.7%, 3.8%/year) subjects by optic disc alone (46 eyes), 38 (44.7%, 5.4%/year) subjects by visual field alone (58 eyes), and 19 (25.0%, 3.0%/year) subjects by both modalities (26 eyes). The average rate of change in MD differed significantly between progressors (-1.02±1.06 dB/y) and nonprogressors (+0.089±0.49 dB/y), P =0.001. The rate of visual field worsening was greater among those who were classified as having progressed by both structure and function (-1.29±0.68 dB/y) and by function alone (-1.21±1.20 dB/y) than by structure alone (-0.55±0.76 dB/y). Progression was significantly associated with older age [odds ratio (OR), 1.42; P <0.001] and higher baseline intraocular pressure (OR, 1.18; P =0.002). Factors associated with rate of MD change were baseline older age (OR, 1.66; P =0.003), higher intraocular pressure (OR, 2.81; P =0.007), better visual field MD (OR, 1.41; P =0.004), and systemic hypertension (OR, 1.15; P =0.029). CONCLUSION: The incidence and rate of visual field progression are high in this longitudinal study of Ghanaian subjects with glaucoma. The findings may have important clinical and public health policy ramifications.

Key correlates of exclusive breastfeeding at three timepoints: Evidence from Ethiopia.

Aim: To compare factors associated with exclusive breastfeeding (EBF) within 1 h of birth, within 3 days, and within the first 6 months post-birth. Methods: We used multivariate logistic regression models and data from "The Alive and Thrive Phase 2 Amhara Baseline Survey 2015" from Ethiopia (N = 3113). Results: Giving colostrum was strongly associated with EBF at all three time points, controlling for multiple confounders. Putting the baby to the breast before cleaning the baby and before cleaning the mother was significantly associated with EBF within 1 h and for the first 3 days. EBF within an hour of birth was more likely for girl babies than boy babies. Having a healthcare professional check whether the baby was sucking well was significantly associated with EBF 3 days post-birth. Conclusions: The World Health Organization recommends breastfeeding within 1 h of birth and exclusively thereafter for 6 months, which can improve health outcomes for infants and children. In Ethiopia, many factors influence breastfeeding practices, but little is known about how these factors differ at various key timepoints in the 6 months after birth. Our study provides important information on correlates of EBF at three timepoints and shows that factors that are significantly correlated with EBF vary over time. Future research should assess the potential causal links among statistically significant associations between EBF and risk factors at various times between birth and 6 months of age. Ultimately, these findings have the potential to inform areas of intervention related to promoting EBF.

Simultaneous CK2/TNIK/DYRK1 inhibition by 108600 suppresses triple negative breast cancer stem cells and chemotherapy-resistant disease.

Triple negative breast cancer (TNBC) remains challenging because of heterogeneous responses to chemotherapy. Incomplete response is associated with a greater risk of metastatic progression. Therefore, treatments that target chemotherapy-resistant TNBC and enhance chemosensitivity would improve outcomes for these high-risk patients. Breast cancer stem cell-like cells (BCSCs) have been proposed to represent a chemotherapy-resistant subpopulation responsible for tumor initiation, progression and metastases. Targeting this population could lead to improved TNBC disease control. Here, we describe a novel multi-kinase inhibitor, 108600, that targets the TNBC BCSC population. 108600 treatment suppresses growth, colony and mammosphere forming capacity of BCSCs and induces G2M arrest and apoptosis of TNBC cells. In vivo, 108600 treatment of mice bearing triple negative tumors results in the induction of apoptosis and overcomes chemotherapy resistance. Finally, treatment with 108600 and chemotherapy suppresses growth of pre-established TNBC metastases, providing additional support for the clinical translation of this agent to clinical trials.
