RESUMEN
BACKGROUND: Evidence on process outcomes such as acceptability, and feasibility of behavior change communication interventions are important in program evaluation to understand how, and why such a program works. However; documented evidence on the issue is not available as far as the social and behavior change communication (SBCC) on malaria is concerned. Enrolling the frontline providers this study measured the acceptability and feasibility of the school-engaged SBCC strategy on malaria prevention in malaria-endemic settings of Ethiopia. METHODS: A school-engaged SBCC strategy involving various communication and capacity-building interventions aimed to advance malaria preventive practices in primary schools in Jimma were implemented from 2017 to 2019. A cross-sectional study was conducted with 205 key stakeholders at the end of the intervention. Both acceptability and feasibility were measured using standardized tools. Data were collected using a structured questionnaire and filled by the study participants. The SPSS version 26 was used to analyze the data. Multivariate general linear modeling was performed to identify the predictors of acceptability and feasibility of the program. P-value < 5% was considered to decide statistical significance. RESULTS: The result showed the mean scores (M, range = R) of acceptability and feasibility of the program were (M = 25.63, R = 6 to 30) and (M = 19.35, R = 5 to 25) respectively. The multivariate linear modeling showed acceptability was affected by self-efficacy; (ß = 0.438, P < 0.001), community support; (ß = 0.417, P < 0.001), school climate; (ß = - 0.16; P = 0.003), perceived malaria threat; (ß = 0.40, P < 0.001) and knowledge; (ß = 0.229, P = 0.013). Similarly, feasibility was influenced by self-efficacy; (ß = 0.352, P < 0.001), community support; (ß = 0.591, P < 0.001), school climate; (ß = - 0.099, P-value < 0.030) and perceived malaria threat; (ß = 0.172, P = 0.002). CONCLUSION: With a considerably high level of acceptability, the school-engaged SBCC strategy to enhance malaria preventive practices seems feasible. The SBCC strategy targeting personal factors such as malaria threat perceptions, knowledge and skills on the program, and contextual factors that include school social climate and community support would be fruitful to facilitate the implementation of the program. The result implicates the benefit of intensifying such a strategy to engage, empower, and retain the education sectors in malaria elimination efforts and beyond.

BACKGROUND: Maternity waiting homes (MWHs), residential spaces for pregnant women close to obstetric care facilities, are being used to tackle physical barriers to access. However, their effectiveness has not been rigorously assessed. The objective of this cluster randomized trial was to evaluate the effectiveness of functional MWHs combined with community mobilization by trained local leaders in improving institutional births in Jimma Zone, Ethiopia. METHODS: A pragmatic, parallel arm cluster-randomized trial was conducted in three districts. Twenty-four primary health care units (PHCUs) were randomly assigned to either (i) upgraded MWHs combined with local leader training on safe motherhood strategies, (ii) local leader training only, or (iii) usual care. Data were collected using repeat cross-sectional surveys at baseline and 21 months after intervention to assess the effect of intervention on the primary outcome, defined as institutional births, at the individual level. Women who had a pregnancy outcome (livebirth, stillbirth or abortion) 12 months prior to being surveyed were eligible for interview. Random effects logistic regression was used to evaluate the effect of the interventions. RESULTS: Data from 24 PHCUs and 7593 women were analysed using intention-to-treat. The proportion of institutional births was comparable at baseline between the three arms. At endline, institutional births were slightly higher in the MWH + training (54% [n = 671/1239]) and training only arms (65% [n = 821/1263]) compared to usual care (51% [n = 646/1271]). MWH use at baseline was 6.7% (n = 256/3784) and 5.8% at endline (n = 219/3809). Both intervention groups exhibited a non-statistically significant higher odds of institutional births compared to usual care (MWH+ & leader training odds ratio [OR] = 1.09, 97.5% confidence interval [CI] 0.67 to 1.75; leader training OR = 1.37, 97.5% CI 0.85 to 2.22). CONCLUSIONS: Both the combined MWH+ & leader training and the leader training alone intervention led to a small but non-significant increase in institutional births when compared to usual care. Implementation challenges and short intervention duration may have hindered intervention effectiveness. Nevertheless, the observed increases suggest the interventions have potential to improve women's use of maternal healthcare services. Optimal distances at which MWHs are most beneficial to women need to be investigated. TRIAL REGISTRATION: The trial was retrospectively registered on the Clinical Trials website ( https://clinicaltrials.gov ) on 3rd October 2017. The trial identifier is NCT03299491 .

BACKGROUND: Obstetric fistula is a hole between the vagina and bladder, and/or between the vagina and rectum, triggered by prolonged obstructed labor. The World Health Organization has estimated that at least 50,000 to 100,000 cases of obstetric fistula occur every year, and that over two million women with obstetric fistula in developing countries remain untreated. Research on women's lived experiences of obstetric fistula is limited. This study aimed to explore the lived experience of women with obstetric fistula at Bahir Dar Hamlin Fistula Center, Amhara Regional State, Ethiopia. METHODS: A qualitative study design, drawing from a phenomenological approach, was employed to explore the lived experience of purposively-selected sample of ten women with obstetric fistula. In-depth interviews were conducted in the local language (Amharic) using an interview guide. Interviews were transcribed and translated into English, and transcripts were entered as primary documents into Atlas.ti 7 software. Thematic categories were identified, and transcripts were coded accordingly. RESULTS: Participants perceived that the contributing factors to obstetric fistula were: instrument-assisted delivery; inappropriate physical examination and care; early marriage; and long duration of labour. As a result of obstetric fistula, the patients suffered from uncontrolled dripping of urine and/or faeces (and associated offensive odours), ostracization by their family and community members, and feeling hopeless and isolation from the community. Patients used different coping mechanisms, including frequent washing of clothes and changing of underwear; they also expressed that they preferred to be alone. CONCLUSION: Women with obstetric fistula experienced urine incontinence and associated bad odour; social and psychological problems like isolation, divorce and fears were commonly reported. Our findings from perspectives of Ethiopian setting suggest that integrated services for women with obstetric fistula are warranted, including physical therapy, psychological support and social reintegration.

BACKGROUND: Infants are in a state of rapid development and maturation; the growth rate is most rapid during the first 4 to 6 months of life. Few studies indicated that in developing countries including Ethiopia the prevalence and duration of breastfeeding is declining and being replaced by formula milk. Therefore, this study aimed to assess the formula-feeding practice and its associated factors among urban and rural mothers with infants 0-6 months of age in the Jimma Zone, Western Ethiopia. METHODS: A community-based cross-sectional study was conducted from November 7, 2015, to January 10, 2016, in the Jimma Zone. The quantitative data were collected from a sample of 714 respondents using a multistage sampling technique. Data were collected through a structured questionnaire and the multivariate logistic regression model was used to show predictors of the formula-feeding practice among mothers with infants 0-6 months of age. RESULT: The proportion of mothers who feed their baby formula-based was 47.2%, of which 34.5% were living in rural areas and 65.5% were living in urban areas. Among the mothers living in urban areas, the likelihood of formula-feeding was significantly associated with maternal educational status and attitude towards formula-feeding. On the other hand, being attended by relatives/friends and the traditional birth attendant was significantly associated with the formula-feeding practice among mothers who live in rural areas. CONCLUSION: Nearly half of the mothers in the study area practice formula-feeding for their infant. Therefore, sustained community based nutritional health education is recommended for pregnant and lactating mothers to reduce the practice of formula-feeding for infants.

BACKGROUND: Homeless women are a highly vulnerable group for risks of pregnancy and childbirth-related complications. They may also face multiple challenges to access and utilize maternity healthcare services. This study was aimed to explore the experience of homeless women on maternity healthcare service utilization and associated challenges in Aksum Town, Northern Ethiopia. METHODS: An exploratory qualitative study was employed using in-depth interviews among 22 study participants from February to March 2016. Purposive sampling was used to recruit 12 homeless mothers who gave birth when being homeless in the last 12 months and 10 healthcare providers as key informants. Data were captured using audio recorders and field notes and transcribed, translated verbatim and thematic analysis approach was facilitated using ATLAS.ti7 software. RESULTS: The finding reveals that homeless women did not use any of the basic maternity health care services, namely antenatal care, skilled birth attendance, and postnatal care. Lack of permanent place and awareness, and fear of stigma and discrimination were some reasons hindering homeless women from using the services. CONCLUSIONS: Even though maternity health service utilization is the most crucial intervention to reduce maternal and newborn deaths, this finding shows that maternity health service utilization among homeless women was limited. Socio-cultural, socioeconomic and healthcare-related factors contributed to the non-use of these services. Efforts should be made to address the challenges faced by homeless women to utilize maternity health services.

BACKGROUND: Maternal and child morbidity and mortality remains one of the most important public health challenges in developing countries. In rural settings, the promotion of household and community health practices through health extension workers in collaboration with other community members is among the key strategies to improve maternal and child health. Little has been studied on the actual roles and contributions of various individuals and groups to date, especially in the rural areas of Ethiopia. In this study, we explored the role played by different actors in promoting ANC, childbirth and early PNC services, and mainly designed to inform a community based Information, Education & Communication intervention in rural Ethiopia. METHODS: An exploratory qualitative study was conducted on 24 in-depth interviews with health extension workers, religious leaders, women developmental army leaders, and selected community members; and 12 focus group discussions, six with female and six with male community members. Data was captured using voice recorders and field notes and transcribed verbatim in English, and analyzed using Atlas.ti software. Ethical approval for the fieldwork was obtained from Jimma University and the University of Ottawa. RESULTS: Participants described different roles and responsibilities that individuals and groups have in promoting maternal/child health, as well as the perceived roles of family members/husband. Commonly identified roles included promotion of health care services; provision of continuous support during pregnancy, labour and postnatal care; and serving as a link between the community and the health system. Participants also felt unable to fully engage in their identified roles, describing several challenges existing within both the health system and the community. CONCLUSIONS: Involvement of different actors based on their areas of focus could contribute to community members receiving health information from people they trust more, which in turn is likely to increase use of services. Therefore, if our IEC interventions focus on overcoming challenges that limit actors' abilities to engage effectively in promoting use of MCH services, it will be feasible and effective in rural settings, and these actors can become an epicenter in providing community based intervention in using ANC, childbirth and early PNC services.

BACKGROUND: Despite improvements in recent years, Ethiopia faces a high burden of maternal morbidity and mortality. Antenatal care (ANC) may reduce maternal morbidity and mortality through the detection of pregnancy-related complications, and increased health facility-based deliveries. Midwives and community-based Health Extension Workers (HEWs) collaborate to promote and deliver ANC to women in these communities, but little research has been conducted on the professional working relationships between these two health providers. This study aims to generate a better understanding of the strength and quality of professional interaction between these two key actors, which is instrumental in improving healthcare performance, and thereby community health outcomes. METHODS: We conducted eleven in-depth interviews with midwives from three rural districts within Jimma Zone, Ethiopia (Gomma, Kersa, and Seka Chekorsa) as a part of the larger Safe Motherhood Project. Interviews explored midwives' perceptions of strengths and weaknesses in ANC provision, with a focus as well on their engagement with HEWs. Thematic content analysis using Atlas.ti software was used to analyse the data using an inductive approach. RESULTS: Midwives interacted with HEWs throughout three key aspects of ANC promotion and delivery: health promotion, community outreach, and provision of ANC services to women at the health centre and health posts. While HEWs had a larger role in promoting ANC services in the community, midwives functioned in a supervisory capacity and provided more clinical aspects of care. Midwives' ability to work with HEWs was hindered by shortages in human, material and financial resources, as well as infrastructure and training deficits. Nevertheless, midwives felt that closer collaboration with HEWs was worthwhile to enhance service provision. Improved communication channels, more professional training opportunities and better-defined roles and responsibilities were identified as ways to strengthen midwives' working relationships with HEWs. CONCLUSION: Enhancing the collaborative interactions between midwives and HEWs is important to increase the reach and impact of ANC services and improve maternal, newborn and child health outcomes more broadly. Steps to recognize and support this working relationship require multipronged approaches to address imminent training, resource and infrastructure deficits, as well as broader health system strengthening.

BACKGROUND: Adolescents especially females in rural area are vulnerable to a wide range of reproductive health problems including sexually transmitted infections, unwanted pregnancies, and unsafe abortion. They have limited access to reproductive health services that focus on the special needs of female adolescents. This study was aimed to assess the determinants of reproductive health service utilization among rural female adolescents of Asgede-Tsimbla district. METHODS: A community-based cross-sectional study was carried out from February to April 2018, in eight randomly selected sub-districts of Asgede-Tsimbla. A total of 844 female adolescents aged 15-19 were interviewed using a pre-tested structured questionnaire. Data were entered into Epi-info Version 3.5.3 and then exported to SPSS Version 21 for analysis. Bivariate and multivariate logistic regression analysis was carried out to assess the association. Statistical significance was declared by 95% confidence interval of the odds ratio. RESULT: From 844 participants, 95.5% of female adolescents heard about reproductive services from different sources and 69.7% of them utilized the reproductive health services within the last 12 months. Factors like, age of 16-20 years (AOR = 1.85, 95%CI: 1.17-2.92), mother's educational status (being illiterate (AOR = .33, 95%CI:.14-.77)), discussion about reproductive health services with their family (AOR = 8.02, 9%CI:5.52-11.66), being Merchant (AOR = 2.7995%CI:1.11-6.96), unemployed (AOR = 2.90, 95%CI:1.19-7.06) or student (AOR:2.38, 95%CI:1.04-5.42) in occupation, high perceived severity (AOR = 4.05, 95%CI:2.68-6.11), high perceived barriers (AOR = .44, 95%CI:.30-64) were independent predictors of reproductive health services utilization among female adolescents the study area. CONCLUSION: About 69.7% of the adolescent females were utilizing reproductive health services in the study area though it was very low as compared with the national plan. Introducing messages that increase the perceived threat and decreasing perceived barriers to utilize reproductive health services as well as increasing self-efficacy of adolescent females would help further increase reproductive health services utilization by adolescent females.

BACKGROUND: The Safe Motherhood Research Project studies the implementation and scale-up of maternal, newborn and child health (MNCH) initiatives in Jimma Zone, Ethiopia. This qualitative rapid assessment study was undertaken to explore community perceptions and experiences related to health, health inequality and other MNCH themes. METHODS: We conducted 12 focus group discussions and 24 in-depth interviews with community stakeholder groups (female and male community members, Health Extension Workers, members of the Women Development Army and Male Development Army, and religious leaders) across six rural sites in Jimma Zone. Data were analyzed through thematic coding and the preparation of content summaries by theme. RESULTS: Participants described being healthy as being disease free, being able to perform daily activities and being able to pursue broad aspirations. Health inequalities were viewed as community issues, primarily emanating from a lack of knowledge or social exclusion. Poverty was raised as a possible contributor to poor health, however, participants felt this could be overcome through community-level responses. Participants described formal and informal mechanisms for supporting the disadvantaged, which served as a type of safety net, providing information as well as emotional, financial and social support. CONCLUSIONS: Understanding community perceptions of health and health inequality can serve as an evidence base for community-level initiatives, including MNCH promotion. The findings of this study enable the development of audience-centered MNCH promotion activities that closely align with community priorities and experiences. This research demonstrates the application of rapid qualitative assessment methods to explore the context for MNCH promotion activities.

BACKGROUND: In Africa, acute intestinal obstruction accounts for a great proportion of morbidity and mortality. Ethiopia is one of the countries where intestinal obstruction is a major cause of morbidity and mortality. This study aims to determine prevalence, causes and management outcome of intestinal obstruction in Adama Hospital in Oromia region, Ethiopia. METHOD: A hospital based cross-sectional study design was used. Data covering the past three years were collected from hospital medical records of sampled patients. The collected data were checked for any inconsistency, coded and entered into SPSS version 16.0 for data processing and analysis. Descriptive and logistic regression analyses were used. Statistical significance was based on confidence interval (CI) of 95 % at a p-value of < 0.05. RESULT: 262 patients were admitted with intestinal obstruction. The prevalence of intestinal obstruction was 21.8 % and 4.8 % among patients admitted for acute abdomen surgery and total surgical admissions, respectively. The mortality rate was 2.5 % (6 of 262). The most common cause of small bowel obstruction was intussusceptions in 48 patients (30.9 %), followed by small bowel volvulus in 47 patients (30.3 %). Large bowel obstruction was caused by sigmoid volvulus in 60 patients (69.0 %) followed by colonic tumor in 12 patients (13.8 %). After controlling for possible confounding factors, the major predictors of management outcome of intestinal obstruction were: duration of illness before surgical intervention (adjusted odds ratio (AOR) = 0.49, 95 % CI: 0.25-0.97); intra-operative findings [Viable small bowel volvulus (SBV) (AOR = 0.08, 95 % CI: 0.01-0.95) and viable (AOR = 0.17, 95 % CI: 0.03-0.88)]; completion of intra-operative procedures (bowel resection & anastomosis (AOR = 3.05, 95 % CI: 1.04-8.94); and length of hospital stay (AOR = 0.05, 95 % CI: 0.01-0.16). CONCLUSION: Small bowel obstruction was more prevalent than large bowel obstruction. Intussusceptions and sigmoid volvulus were the leading causes of small and large bowel obstruction. Laparotomy was the most common methods of intestinal obstruction management. Bowel resection and anastomosis was the commonest intra-operative procedure done and is associated with postoperative complications. Wound infection in the affected area should be improved because it is the most common postoperative complication. This can be decreased by appropriate surgical technique and wound care with sterile techniques.

The motivation for constructing a thin-shell wormhole from a (2+1)-dimensional rotating black hole arises from the desire to study the effects of a nonminimally coupled scalar field in this particular spacetime. By investigating the behavior of such a field in the presence of rotation, we can gain insights into the interplay between gravity and scalar fields in lower-dimensional systems. Additionally, this construction allows us to explore potential connections between black hole physics and exotic phenomena like traversable wormholes. The radial perturbation around the equilibrium throat radius is considered to explore the stable configuration for specific values of physical parameters. Then, the equations of state, specifically the phantom-like and generalized Chaplygin gas model for exotic matter is used to conduct an extensive investigation into the stability of the counter-rotating thin-shell wormholes. Our results show that the presence of a scalar field enhances the stability of the counter-rotating thin-shell wormholes.
RESUMEN
Background: Contraception is the information, devices, and medications that enable individuals to decide whether and when to have children. It is a cost-effective method of limiting and spacing childbirth. In Ethiopia, the prevalence of modern contraceptives is increasing, and injection contraceptives represent a high prevalence. However, it is unclear why the women preferred injection contraception. Objective: To explore Women's experiences on contraceptive preference among Jimma town public health facilities, southwest Ethiopia, 2023. Methods: An interpretative phenomenological study design was employed. Women aged between 18 and 49 who have been using injectable contraceptives for more than one year were our study population. Data were collected through in-depth interviews using an open-ended, structured interview guide. The purposive sampling technique was used to select 12 participants from three randomly selected public health facilities in Jimma town. Audio data were transcribed verbatim into word files, and finally, Atlas.ti 7.0 software was used to facilitate coding and categorizing. Results: Twelve women who have been using injectable contraceptives for the last year were involved in this study. Religious beliefs, fear of side effects, visiting Arab countries, and previous contraceptive experiences were the main reasons for respondents to prefer injectable contraceptive methods. This study revealed that women were experiencing positive and negative effects while using injection contraceptives. The majority of the respondents felt comfortable and pleased and had not encountered any health-related issues since beginning to use injection contraceptives. Conclusion: The key factors influencing respondents' preference for injection methods of contraception included fear of side effects, religious convictions, travel to Arab nations, and prior contraceptive experiences. The majority of respondents felt at ease and pleased and reported no substantial health difficulties associated with injection contraception, despite a few women reporting minor adverse effects. Therefore, switching to long-acting methods of contraception necessitates increased women's understanding of contraceptives.

OBJECTIVE: Recently, the Turiyam set was introduced as an extension of the neutrosophic set to handle the uncertainty data set beyond its truth, indeterminacy and falsity values. This article introduced the Cartesian product of Turiyam sets and Turiyam relations. Further, we defined operations on Turiyam relations as well as discussed the inverse and types of Turiyam relations. RESULTS: The Cartesian product of Turiyam sets, Turiyam relations, inverse Turiyam relation and types of Turiyam relations are stated and their properties are derived. Furthermore, examples are given to clarify some concepts.
RESUMEN
OBJECTIVES: The notion of Bipolarity based on positive and negative outcomes. It is well known that bipolar models give more precision, flexibility, and compatibility to the system as compared to the classical models and fuzzy models. A bipolar fuzzy graph(BFG) provides more flexibility while modeling human thinking as compared with a fuzzy graph, and an interval valued bipolar fuzzy graph(IVBFG) has numerous applications where the real-life problem are time dependent and there is a network structure complexity. The aim of this paper is to introduce an interval-valued bipolar line fuzzy graph(IVBFLG). RESULT: In this paper, we have proposed the notion of an IVBFLG and some of its characterizations. Also, some propositions and theorems related to an IVIFLGs are developed and proved. Furthermore, isomorphism between two IVIFLGs toward their IVIFGs was determined and verified. As a result, we derive a necessary and sufficient condition for an IVBFG to be isomorphic to its corresponding IVBFLG and some remarkable properties like degree, size, order, regularity, strength, and completeness of an IVBFLGs have been investigated, and the proposed concepts are illustrated with the examples.

Chemical graph theory is a well-established discipline within chemistry that employs discrete mathematics to represent the physical and biological characteristics of chemical substances. In the realm of chemical compounds, graph theory-based topological indices are commonly employed to depict their geometric structure. The main aim of this paper is to investigate the degree-based topological indices of dominating David derived networks (DDDN) and assess their effectiveness. DDDNs are widely used in analyzing the structural and functional characteristics of complex networks in various fields such as biology, social sciences, and computer science. We considered the FN*, [Formula: see text], and [Formula: see text] topological indices for DDDNs. Our computations' findings provide a clear understanding of the topology of networks that have received limited study. These computed indices exhibit a high level of accuracy when applied to the investigation of QSPRs and QSARs, as they demonstrate the strongest correlation with the acentric factor and entropy.
RESUMEN
OBJECTIVE: A single valued neutrosophic set represented the uncertainty of real life situations in terms of membership [Formula: see text], indeterminacy [Formula: see text] and non-membership [Formula: see text] degree. However, this uncertainty cannot be limited to those three degrees; there is also an additional refusal degree. For this issue, the Turiyam set is an appropriate tool, which described the neutrosophic refusal degree of this situation as a liberal [Formula: see text] degree in addition to those three degrees. The graphical representation of this situation is required for knowledge processing. For this purpose, the Turiyam graph was introduced as an extension of the single valued neutrosophic graph. This graph is helpful when the depictions of the vertices or their relationships or both, are considered in terms of membership [Formula: see text], indeterminacy [Formula: see text], non-membership [Formula: see text] and liberal [Formula: see text] degrees. The goal of this paper is to introduce the degree, order and size in the context of Turiyam graphs and examine a social network (SN) with the help of this graph. RESULTS: In this regard, the degree, order and size in the context of Turiyam graphs are studied. The feasibility of this Turiyam graph is shown by employing its concept in a social network (SN). Finally, the advantage of the Turiyam graph over the existing graph theories is recognized by viewing its better framework.

RESUMEN
Introduction: cervical cancer is a global public health problem affecting women worldwide. There is very low participation rate in screening practice for cervical cancer in low-resource countries like Ethiopia. So the aims of this study is to assess cervical cancer screening practice and associated factors among women employees in Wolaita Zone hospitals, Southern Ethiopia. Methods: facility based cross-sectional study design was conducted from March 1-April 30, 2017. Simple random sampling technique was employed to select 401 study participants. Pre-tested self-administered questionnaire was used. Logistic regression was performed to assess association between dependent and independent variables with 95% confidence interval (CI) and p-value less than 0.05 was set to declare association. Results: about 120 (30.5%) participants were screened for cervical cancer. Age, source of information from health professions, being adherence supporter, sex with more than one partner, sexual transmitted infection, increase in attitude and knowledge score were significant predictors of cervical cancer screening practice. Conclusion: magnitude of cervical cancer screening practice among age eligible women is still low. Age, being adherence supporter, source of information from health care professionals, history of multiple sexual p artners, sexually transmitted infection, knowledge and attitude were important predictors of cervical cancer screening practice. Hospitals in collaboration with town administration should put priority on cervical cancer prevention by establishing cervical cancer screening campaign.

OBJECTIVES: In the field of graph theory, an intuitionistic fuzzy set becomes a useful tool to handle problems related to uncertainty and impreciseness. We introduced the interval-valued intuitionistic fuzzy line graphs (IVIFLG) and explored the results related to IVIFLG. RESULT: Some propositions and theorems related to IVIFLG are proposed and proved, which are originated from intuitionistic fuzzy graphs (IVIG). Furthermore, Isomorphism between two IVIFLGs toward their IVIFGs was determined and verified.
