Background: Healthcare-associated infections occur in patients under medical care, which is a major public health issue in hospitals worldwide. The prevalence is two to three folds higher in developing countries compared to developed countries. Inanimate objects used by healthcare professionals such as gowns, mobile phones, and stethoscopes are highly prone to bacterial contamination from the healthcare setting. In Ethiopia, there is a paucity of published data on the bacterial profile and susceptibility patterns of an isolates.
Objective: To determine the bacterial profile and antimicrobial susceptibility patterns from inanimate objects used by healthcare professionals and associated factors at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.

Background: Healthcare-associated infections occur in patients under medical care, which is a major public health issue in hospitals worldwide. The prevalence is two to three folds higher in developing countries compared to developed countries. Inanimate objects used by healthcare professionals such as gowns, mobile phones, and stethoscopes are highly prone to bacterial contamination from the healthcare setting. In Ethiopia, there is a paucity of published data on the bacterial profile and susceptibility patterns of an isolates.
Objective: To determine the bacterial profile and antimicrobial susceptibility patterns from inanimate objects used by healthcare professionals and associated factors at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.
Methods: A cross-sectional study was conducted at Debre Markos Comprehensive Specialized Hospital from inanimate objects from April 10, 2023 to June 30, 2023 using simple random sampling technique with lottery method. Socio-demographic data was collected using a structured questionnaire. A swab sample from healthcare professionals' gowns, mobile phones, and stethoscopes were collected and inoculated onto blood agar, chocolate and MacConkey agar. Isolates were identified and characterized by colony morphology, Gram staining and biochemical tests. Antimicrobial susceptibility testing was performed in all isolates by the disk diffusion technique on Muller Hinton agar according to CLSI, 2022 guidelines. Data was entered into EPI-Data and analyzed using SPSS version 25. Logistic regression model was used. Variables with p-value ≤ 0.25 in bivariable logistic regression was fitted to multivariate logistic regression analysis. A p-value of ≤ 0.05 with 95%CI was considered statistically significant.
Result: A total of 376 healthcare professionals' inanimate objects were included from 191 study participants. Overall, 60.1% (226/376) (95%CI: 55.1-65) inanimate objects were contaminated. The proportion of bacterial contamination was (65.1%; 82/126), (60.3%; 76/126) and (54.8%; 68/124) for mobile phones, gowns and stethoscopes, respectively. Staphylococcus aureus was the most frequent isolate accounting (22.1%; 83/376) followed by Staphylococcus epidermidis (17.0%; 64/376), Escherichia coli (8.8%; 33/376) and Pseudomonas aeruginosa (4.9%; 18/376). Working in gynecology/ obstetrics wards (AOR: 8.69; 95%CI: 1.09-69.41, P = 0.041), did not disinfect mobile phones (AOR: 2.69; 95%CI: 1.15-6.25; P = 0.021) and stethoscopes regularly (AOR: 3.06, 95%CI: 1.23-7.59; P = 0.016), carry mobile phones with patient care materials (AOR: 2.72; 95%CI: 1.18-6.29, P = 0.019) and not taken infection prevention training (AOR:3.91; 95%CI:1.71-8.93; P = 0.001) were significantly associated with bacterial contamination.Most Gram-negative bacteria were resistant to ampicillin, trimethoprim-sulfamethoxazole and amoxacilline-clavunic acid, while Gram-positive isolates showed high level of resistant to penicillin. On the other hand, meropenem, for Gram-negative and clindamycin for Gram-positive bacteria showed lower level of resistance. Multidrug resistance among Gram-positive and Gram-negative bacteria were (62.6%; 92/147) and (75.3%; 64/85), respectively with over all MDR (67.2%, 156/232).
Conclusion: Inanimate objects commonly used by healthcare professionals are important sources of bacterial contamination. S. aureus, S. epidermidis and E. coli were the predominant isolates. Most Gram-negative bacteria were resistant to ampicillin while Gram-positive isolates showed high level of resistant to penicillin. All healthcare professionals should regularly disinfect their inanimate objects to prevent bacterial colonization and potential spread of infection.

Abstract Preview:
In many regions of Ethiopia, particularly in the study area, high-quality livestock feed is scarce, particularly during the dry season.Indigenous browse species could potentially ofer alternative sources of feed, but their potential has not been fully exploited, owingto a lack of detailed information. Without detailed information on the nutritional value of indigenous browse species, it is difcultto assess their suitability as feed sources. Tis knowledge gap indicates that even if these plants are abundant, they may not be usedefectively because their nutritional benefts are not well understood. Te objective of the present study was to fll this gap bysystematically evaluating the biomass yield and nutritional content of indigenous browse species. Te mean biomass yields forvarious indigenous browse species varied signifcantly (p < 0.05) among species, with Ficus thonningii producing the highest,whereas the biomass yields of Vernonia amygdalina were the lowest. Arundinaria species exhibited the highest NDF content(68.5%), whereas V. amygdalina had the lowest NDF content (46.8%). Te crude protein content varied signifcantly (p < 0.05)among the species, with Acacia albida having the highest (20.3%), whereas the crude protein content of Carissa edulis was thelowest (13.3%). Hence, the crude protein content of all indigenous browse species is sufcient to meet the maintenance needs ofcattle, sheep, and goats because, as stated by Kearl and NRC, the crude protein levels required for maintenance in these animalsrange from 7% to 10%. Te crude protein content of indigenous browse species is sufcient to meet the milk production re-quirements of sheep and goats because the crude protein levels required for milk production for these animals range from 12% to16%. For lactating dairy cows and growing beef cattle, Kearl recommended CP values of 14%–18% and 12%–16% required,respectively. Terefore, indigenous livestock producers should incorporate these species into their production systems to enhanceproductivity. Tis approach can also help mitigate the high costs associated with concentrate feeds, which are typically expensive.Keywords: biomass; browse species; nutritional composition; species composition

This research has been designed to explore some choreographic matters of selected Amharic Music, and it has employed stylistics approach in association with the musical functions or thematic purposes related to visual narrative inquiry.
The rationale behind the research project was related to the discussion of some choreographic maters of this study in relation to theme, creativity and deviation related to the videos of the selected music, for such practice has been less experienced in researches before. This is so, for people in most of the time perceive the choreographic matters or form related issues of music and the thematic function which could be transferred through the videos as independent concerns. However, form and content of a certain artistic production are the two sides of a coin which could not be investigated and understood independently; this is so, for, it is obvious that what is made on the form is all about the content of any artistic production and vice-versa. This was made in this study with the discussion of the concept, choreographic matters of some selected Amharic Music made on the presupposed themes advocated by the videos in relation to the range of creativity and deviation.
Therefore, the intention of the current study was to deal with the exploration of choreographic matters as reflected in the musical videos in relation to creativity and deviation made to convey thematic matters of the videos, for these two artistic concepts (creativity and deviation) are the inevitable techniques of music as one genre of fine art. The study has been concluded with the following demonstration.

On top of their own peculiarities, all the videos are similar in their disclosure of artistic creativities experienced both in content and form levels. This creativity extends the range of experiencing artistic deviations. At least all the selected videos commonly share the ideas in dealing with the videos potential of keeping traditional dance movements, the range of improvisations and expressiveness inculcated in line with modernizing the dances in the videos and the intentional and unintentional global influences and hybridizations.

Background: Cisplatin-based chemotherapy regimen associated nephrotoxicity is a significantadverse effect that restricts the standard dose of cisplatin by impairing renal function. There is alack of data on cisplatin-based chemotherapy-induced nephrotoxicity (CIN) in Ethiopian patientswith gynecological cancer. This study evaluated the factors associated with CIN and its impact onthe survival status of patients with gynecological cancer at Northwest Ethiopia oncology centers.Methods: This institutional-based retrospective cohort study included patients with gynecologicalcancer who received cisplatin-based chemotherapy between 2020 and 2021 at NorthwestEthiopia oncology centers. CIN was evaluated using the Common Terminology Criteria forAdverse Events (CTCAE) version 4 criteria and Kidney Disease Improving Global Outcomes(KDIGO) Guideline. A logistic regression model was used to identify the factors associated withCIN. The Cox proportional hazards regression model was used to determine the impact of CINonpatients survival. The cutoff point was a P value of < 0.05 for declaring statistical significance.Results: A total of 394 patients with gynecological cancer were included in the final analysis. Theincidence of CIN was 27.9 % (95 % CI 23.4,32.7). Old age (≥60 years) [adjusted odds ratio(AOR)=1.7,95 % confidence interval (CI) (1.1–2.9); P=0.039],low serum albumin (50 mg/m2) [AOR=2.6,95% CI (1.4–4.7), P=0.002]were significantly associated with CIN.CIN[(adjusted hazard ratio(AHR)=3.2,95 % CI (2.7–9.5), P=0.004]and cisplatin dose reduction [AHR=2.7,95 % CI(1.7–4.3) P=0.021] were significant factors of death among patients with gynecological cancer.Conclusion: More than a quarter of patients receiving cisplatin-based chemotherapy developedCIN, which negatively affected their survival. This study recommends that prescribers pay specialattention to patients with older age, lower serum albumin levels, and high-dose cisplatin toimprove renal function and survival. Cisplatin-based chemotherapy-induced nephrotoxicitysignificantly affects the survival of gynecological cancer patients.

This study aims and documents the clinical and laboratory diagnosis of bovine dermatophilosis, caused by Dermatophiluscongolensis that causes exudation and matting of hairs and wools with the formation of crusts and scab. An adult local breed bullwith a history of reduced appetite, pruritus, dirty scabs and crusts as initial lesion coalesce on its different body parts was presentedto Debre Markos multipurpose veterinary clinic. The rectal temperature and other vital parameters were within the normalrange. The clinical signs observed were exudative dermatitis forming crusts and scabs, pruritus, matted hair like a paintbrushand keratinized material creating wart-like lesions that were widely distributed in different body parts. Few ticks were observedon the skin of the bull suspected as vector of the disease. Culture of skin scraps on blood agar showed small, grayish-white raisedgranular and hemolytic colonies. Staining of skin scraps by Giemsa and Gram’s stain and cultured colony by Gram’s stain indicatedthe characteristics of Dermatophilus congolensis, etiology of dermatophilosis. Other laboratory tests also showed the characteristicsof D. congolensis. The case was treated by penstrep and ivermectin parentally and iodine tincture topically, and the bull showedprogressive clinical improvement and complete recovery within 2 months. In conclusion, dermatophilosis is an economicallyimportant skin disease, highly prevalent in Ethiopia, and needs early detection and treatment by penstrep intramuscularly andivermectine subcutaneously with iodine tincture topically in line with proper husbandry practices to control the losses.

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.

Full Abstract:
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.

This study investigates the performance of hemispherical solar stills (HSS) enhanced with date kernelsand olive kernels as heat storage materials to improve water distillation efficiency. By utilizing thesenatural and sustainable materials, the research highlights an alternative to synthetic options. Rigorousexperimentation and detailed analysis under identical conditions reveal that both kernels significantlyimprove heat retention and water production rates. The HSS with date kernels (HSSDK) achieved adaily water productivity of 6.66 kg/m2 day, representing an efficiency increase of 10.87%, while theHSS with olive kernels (HSSOK) produced 8.00 kg/m2 day, enhancing efficiency by 13.54%. The cost perm3 of distilled water for HSSDK is approximately USD 4.65, while HSSOK costs USD 3.89, comparedto USD 7.83 for the conventional CHSS system. These results demonstrate that the inclusion of heatstorage materials has significantly reduced the cost of water production, with reductions of about 40%for HSSDK and 50% for HSSOK compared to the conventional system. These results are attributedto the high thermal conductivity and specific heat capacities of the kernels, enabling effective heatstorage and gradual release. This study demonstrates the potential of agricultural by-products ascost-effective and sustainable solutions for solar water distillation. Further research is recommendedto optimize the quantities and configurations of these materials, as well as to explore their integrationwith other renewable energy systems to enhance overall efficiency and sustainability.Keywords: Hemispherical solar still, Date kernels, Olive kernels, Heat storage materials, Distillation efficiency

Abstract Preview:
This study examines the commitment and compliance of two key rebel groups in the Ethiopian Civil War—theTigray People’s Liberation Front and the Oromo Liberation Front—to international human rights norms, utilizingthe Jo and Bryant framework of human rights commitment and compliance for non-state actors as an analyticaltool. A systematic secondary document analysis was conducted, with data sourced from national and interna-tional media outlets, as well as reports from humanitarian organizations. The Tigray People’s Liberation Front ischaracterized by a more centralized and disciplined organizational structure, which has facilitated greateraccountability for its actions. In contrast, the Oromo Liberation Front has faced significant internal fragmentationand weak command, complicating the attribution of responsibility. Despite these organizational differences, bothgroups share a record of serious human rights violations, including the mistreatment of prisoners of war, masscivilian killings, forced displacements, and the use of child soldiers. While neither group fully adheres to humanrights standards, the Tigray People’s Liberation Front has demonstrated a relatively greater capacity to facilitatehumanitarian aid, although this aid is frequently diverted for military purposes, undermining its intendedsupport for civilians. This diversion reflects a troubling pattern of aid misappropriation that compromises theeffectiveness of humanitarian efforts in conflict zones. Conversely, the Oromo Liberation Front’s lack of coop-eration with humanitarian agencies further exacerbates the suffering of affected populations, underscoring theneed for both groups to reassess their commitment to humanitarian principles and the protection of civilianrights. The study calls for international actors to exert pressure on both groups to ensure compliance with at leasta minimum standard of human rights norms.
