IntroductionCancer is a leading cause of global morbidity and mortality, significantly impairing patients’quality of life (QoL). Integrated Palliative Care (IPC) has been proposed as a holisticapproach to enhance quality of life by addressing patients’ physical, emotional, and psy-chosocial needs. While some studies suggest Integrated Palliative Care improves qualityof life more than standard care, the evidence remains inconclusive. This systematic reviewand meta-analysis aim to evaluate the comparative impact of Integrated Palliative Careversus standard care on the quality of life in cancer patients.MethodsA comprehensive search of databases including PubMed, Cochrane Library, and Embase wasconducted. We selected randomized controlled trials (RCTs) comparing Integrated Palliative Careand standard care for cancer patients, focusing on the quality of life as measured by validatedtools such as the EORTC QLQ-C30 and FACT-G. Data were pooled using a random-effectsmodel to account for study heterogeneity. Subgroup and sensitivity analyses were also performed.ResultsNine randomized controlled trials involving 1,794 patients met the inclusion criteria.Meta-analysis showed that Integrated Palliative Care significantly improved quality oflife compared to standard care (SMD = 3.25; 95% CI: 1.20–5.30; p < 0.001). Studiesconducted in Asia showed the highest standardized mean difference (SMD = 6.15; 95%CI: 3.07–9.23; p < 0.001), followed closely by studies from Africa (SMD = 6.0; 95% CI:5.13–6.87; p < 0.001), compared to those from other regions. Similarly, research focusingon lung cancer patients showed the greatest standardized mean difference of (SMD =6.15; 95% CI: 3.07–9.23; p < 0.001) relative to other cancer types. Furthermore, studies
involving newly diagnosed cancer patients recorded the highest standardized mean differ-ence of (SMD = 5.69; 95% CI: 4.57–6.80; p < 0.001).ConclusionIntegrated Palliative Care significantly enhances the quality of life in cancer patients comparedto standard care. These findings support integrating Integrated Palliative Care into oncologypractices to provide comprehensive, patient-centered care that addresses both physical andemotional needs. Further research should explore long-term benefits across diverse populations.

ABSTRACT While it is dependent on erratic rainfall and subject to drought and low productivity, agriculture is still the dominant economic activity in Ethiopia. Climate-Smart Agriculture (CSA) technology adoption enhances productivity, resilience, and climate mitigation, yet its adoption by smallholder farmers in Ethiopia’s West Gojjam Zone remains limited despite government promotion. However, research on the factors behind the determinants of the low adoption rate is limited in the study area. The main objectives of this study were to investigate the factors influencing the adoption of five CSA-aligned practices: crop diversification, livestock diversification, irrigation, agroforestry, and the application of chemical fertilizers across selected woredas. Data were generated using structured questionnaires, key informant interviews, and focus groups from a total of 236 households selected using a multistage sampling technique. The analysis made by a multivariate probit model revealed that significant determinants included the gender of the household head, education, farm size, income, irrigation access, credit availability, extension services, and farming experience. Findings suggest that enhancing crop and livestock diversification requires expanding irrigation access, strengthening extension services, and integrating climate-smart advisory programs to equip farmers with essential skills and resources. Additionally, improving credit access, providing climate information through mobile phone SMS for free, and promoting farmer training can boost irrigation adoption, while targeted awareness campaigns can encourage experienced farmers to adopt modern irrigation technologies. Keywords: Adoption; Climate-Smart Agricultural Practices; Multivariate probit, West Gojjam

Method Twenty inactive males (BMI 27.67 ± 0.88 kg/m2 , age 49.15 ± 2.58 years) participated in an eight-week wererandomly assigned to one of three intervention groups (combined (CT), resistance (RT), and aerobic (AT)) exercisemodalities to assess within-subject and between group changes in glycolipid profile. Data were analyzed usingrepeated measures ANCOVA.Result Pre-post mean values of body fat percentage (%BF), area under the curve (AUC), low density lipoprotein (LDL),high density lipoprotein (HDL) and total cholesterol (TC) decreased in all three groups. The main effect of exercisemodality on the AUC (F (2, 26) = 10.577, P = 0.001, η2 = 0.569) was significant. Post-hoc analyses revealed that the RTgroup (-30.653 ± 6.766, p = 0.001) with 11.53% and the CT group (M = -0.896, SE = 3.347, P = 0.015) with 3.79% exhib-ited significantly greater reductions in AUC compared to the AT group.

Abstract Preview:
Background: Hepatitis B virus (HBV) is highly infectious and poses significant global health challenges. Healthcare workers (HCWs) are particularly at risk of HBV infection due to occupational exposure through contact with infected blood or body fluids. To mitigate this risk, hepatitis B vaccination is recommended for all healthcare workers and is administered in three doses at 0, 1, and 6 months, aiming to reduce exposure and provide immunity against the virus. However, the effectiveness of the HBV vaccine remains uncertain in the study area.
Objective: This study aimed to evaluate hepatitis B vaccine efficacy and factors affecting vaccine effectiveness among healthcare workers in all Hospitals of East Gojjam Zone Amhara Region, North West Ethiopia
Materials and Methods: A hospital-based cross-sectional study was conducted among 422 healthcare workers from March 25, 2024, to November 30, 2024. Simple random sampling technique was used to recruit the study participants. Total sample size was allocated proportionally to each hospital. Socio-demographic and clinical data were collected using a pretested structured questionnaire. Moreover, venous blood samples (4–5 ml) were collected from the study participants, and serum samples were analyzed to measure and detect the concentrations of anti-hepatitis B surface antigen (anti-HBs), hepatitis B surface antigen (HBsAg), and anti-hepatitis B core antibody (anti-HBc) using a sandwich enzyme-linked immunosorbent assay (ELISA). Additionally, hepatitis B virus DNA (HBV DNA) was assessed using real-time polymerase chain reaction (qPCR). Data were analyzed using SPSS software version 25. Logistic regression model with 95% CI was used to show the statistical association. P value < 0.05 was considered as statistically significant.

Logistic regression model with 95% CI was used to show the statistical association. P value < 0.05 was considered as statistically significant.
Results: The overall sero-prevalence of HBsAg among all study participants was 23/422 (5.5%) (95% CI: 3.0-8.0). In multivariable logistic regression, blood transfusion (AOR: 16.5, 95% CI: 1.53, 29.24) (P<0.011) and dental extraction (AOR: 13.5, 95% CI: 3.99, 45.57) (P<0.000) were significantly associated with HBsAg positivity. In addition, the overall sero-reactivity of anti-HBc was 30/422 (7.1%) (95% CI: 5.0-10.0). Injectable medication (AOR: 4.3, 95% CI: 1.73, 10.72) (P<0.002) was significant determinant for anti-HBc sero-positivity. Furthermore, of fully vaccinated healthcare workers, 346/422 (82.0%) (95% CI: 78.0- 86.0 %) of them were sero-protected (had anti-HBs titer ≥ 10 mIU/ml). The paradoxical sero-positivity of HBsAg and anti-HBs among fully vaccinated healthcare workers was 16(4.6%). Moreover, among HBsAg-positive individuals, HBV DNA was detected in 17 (73.9%) of them.
Conclusions and recommendations: The study identified intermediate HBV seroprevalence among vaccinated healthcare workers, indicating suboptimal vaccine efficacy. These findings emphasize the necessity of monitoring post-vaccination anti-HBs antibody levels to address gaps in protection.

This study suggests an enhanced version of the adaptive fuzzy fast terminal synergetic controller(AF-FTSC) for controlling the uncertain DC/DC buck converter based on the synergetic theory ofcontrol (STC) and newly developed terminal attractor technique (TAT). The benefits of the proposedSC algorithm involve the features of finite-time convergence, unaffected by parameter variations, andchattering-free phenomenon. A type-1 fuzzy logic system (T1-FLS) make the considered controllermore robust and is utilized to estimate the undefined converter nonlinear dynamics without resortingto the usual linearization and simplifications of the converter model. Taking a switching DC-DC buckconverter as a demonstration, the suggested AF-FTSC is thoroughly analyzed and executed on adSPACE ds1103 controller board. The outcomes of the experiment confirm the competence andapplicability of the suggested regulator.Keywords: Synergetic control, Fuzzy logic system, Fast terminal method, Finite-time convergence, DC/DCbuck converter

Abstract: Food insecurity in peri-urban areas is exacerbated by high living costs, limited access tohealthy food, and economic inequality. Despite its growing prevalence due to factors like land lossfrom urban expansion, food insecurity has received limited attention. In Ethiopia, drastic urbanizationcreates competition for land between agriculture and urban development, which is becoming extremein peri-urban areas., This study aims to assess the impact of urban expansion on food security amongexpropriated peri-urban households in Ethiopia. Using a calorie intake-based food security line, wecategorize respondents as food-secure or -insecure. The research analyzed data from 350 expropriatedperi-urban households through a structured questionnaire, employing descriptive statistics andbinary logistic regression. About 67% of the respondents were classified as food-insecure. The binarylogit model identified several significant determinants of food security, including compensationamount and type, household head demographics, agricultural land rent participation, irrigationand credit access, off-farm income, and organic fertilizer use. To address food insecurity amongexpropriated households, policymakers must prioritize these factors. Government attention andpolicy consideration are crucial to ensure the well-being of these vulnerable populations.Keywords: urban expansion; food insecurity; calorie intake; expropriation; Ethiopia

ABSTRACT Background: Blood donation is vital for saving lives, yet Ethiopia faces chronic shortages. Bridging the gap between willingness and actual donation is essential for sustaining blood supplies. This study examined socio-demographic, psychological, and contextual factors influencing blood donation intention and practice in East Gojjam Zone. Methods: A community-based cross-sectional survey of 1,332 urban adults who met inclusion criteria was conducted using multistage cluster sampling. Data were collected via a structured, pre-tested questionnaire. Descriptive statistics summarized donation patterns, while binary logistic and Zero-Inflated Negative Binomial regressions identified predictors of donation intention and frequency, respectively. Structural Equation Modeling (SEM) examined associations among socio-demographic characteristics, psychological factors, donation intention, practice, and behavior. Results: Although 74.8% (95% CI: 72.5–77.1) expressed willingness to donate, only 28.8% (95% CI: 26.4–31.2) had ever donated, and 20.7% (95% CI: 18.5–22.9) had donated in the past two years. Male gender, younger age, higher education, and employment in health or education sectors positively predicted intention and practice. Psychological factors—including self-efficacy (β = 0.53), positive attitudes (β = 0.46), knowledge (β = 0.38), altruism, and social influence (β = 0.28)—were strongly associated with donation. SEM confirmed that intention strongly predicted actual donation (β = 0.62). Barriers included fear of needles, health concerns, and limited awareness. Conclusions: Despite high willingness, actual donation remains low. Multi-sectoral, culturally sensitive strategies—addressing fears, improving knowledge, leveraging social influence, and enhancing accessibility—are critical, especially for women, older adults, and less-educated individuals, to build a resilient, community-driven blood supply. Keywords: Blood donation, intention, practice, socio-demographic factors, psychological determinants, Ethiopia, Structural Equation Modeling
