The Amhara region has experienced prolonged conflict, raising concerns about its impact on healthcare delivery. Understanding the extent of these disruptions is crucial for informing policy responses and humanitarian interventions.
Objectives: This systematic review and meta-analysis aimed to assess the impact of armed conflict on healthcare delivery in the Amhara region.
Study design: Systematic review and meta-analysis.
Methods: Conducted between June 1 and July 10, 2024, this meta-analysis followed PRISMA guidelines. A comprehensive search was performed across PubMed/MEDLINE, EMBASE, CINAHL, Google Scholar, ScienceDirect, and the Cochrane Library. Eligible studies included English-language observational studies and grey literature addressing healthcare disruptions, infrastructure damage, and health crises. Data were analyzed using STATA Version 14, and study quality was assessed using a modified Newcastle-Ottawa Scale.
Results: Twelve studies, encompassing 12,037,279 participants, were included. The pooled prevalence of health impacts was 76.71 % (95 % CI: 76.63-76.78). The conflict rendered 60 % of healthcare facilities nonfunctional, disrupted medical supplies for 70 % of the population, and reduced service availability by 80 %. Chronic disease management, mental health services, maternal care, and immunization programs experienced significant declines. Subgroup analyses indicated a higher prevalence of health impacts in studies published after 2022 (70.72 %) compared to those published before 2022 (28.35 %).
Conclusion: Armed conflict in the Amhara region has severely disrupted healthcare services, leading to facility closures, medical supply shortages, and significant declines in essential health services. Urgent interventions are required to restore healthcare infrastructure and services.

Abstract Preview:
Introduction Depression and anxiety are prevalent psychological disorders that significantly affect physical,emotional, and social well-being, reducing quality of life and increasing medical costs. These issues are especiallychallenging for cancer survivors, complicating treatment management, affecting adherence, and potentiallyimpacting survival rates. Thus, this umbrella review aimed to evaluate the global prevalence of pain, depression, andanxiety, as well as their determinants among cancer patients.Method An exhaustive umbrella review was conducted to systematically assess the prevalence and determinants ofpain, depression, and anxiety among cancer survivors worldwide by analyzing systematic reviews and meta-analyses.The review involved a thorough search of multiple databases and included studies published in English up to July2024 that reported on these symptoms. The process involved screening and selecting studies based on specificcriteria, assessing the risk of bias using the AMSTAR tool, and analyzing data with statistical methods to determineoverall prevalence and identify predictors. This comprehensive approach aimed to provide a detailed understandingof these psychological issues in cancer survivors and guide future research and interventions.Result The global summary prevalence of depression among cancer survivors was 33.16% (95% CI 27.59–38.74),while anxiety had a prevalence of 30.55% (95% CI 24.04–37.06). Pain prevalence after treatment was 39.77% (95%CI 31.84–47.70). Before treatment, 65.22% (95% CI 62.86–67.57) of cancer patients reported pain, which persistedin 51.34% (95% CI 40.01–62.67) during treatment. The analysis also found that during the COVID-19 pandemic,depression and anxiety rates among cancer patients were at their highest, with prevalences of 43.25% (95% CI41.25–45.26) and 52.93% (95% CI 50.91–54.96), respectively.Conclusion The umbrella review found that depression and anxiety prevalence among cancer survivors was33.16% and 30.55%, respectively, with significantly higher rates during COVID-19 at 43.25% and 52.93%. Key factorscontributing to depression included poor social support, advanced cancer stage, and inadequate sleep, while anxietywas significantly linked to advanced cancer stage and poor sleep quality.

Extreme flood and drought events arise from temporal and spatial variations in the Earth’s water cycle, signif-icantly affecting water resources and the environment. This review aimed to evaluate the effects of climatevariabilities on extreme flood and drought events within the Blue Nile Basin. A systematic literature review andcontent analysis were conducted to understand the hydrological dynamics of floods and droughts. A Scopusdatabase was used to find relevant literature review articles related to flood and drought extreme events usingsearch terms queries. The findings suggest that rising temperatures and fluctuating precipitation patterns areleading to more frequent and severe floods and droughts. Future projections also suggest increased droughtseverity in most basin areas, coupled with more frequent floods. Fluctuations between dry and wet conditionshave intensified these extremes. While insufficient rainfall triggers droughts, excessive and concentrated rainfallcontributes to floods. The wet projection shows more frequent floods, while the dry projection indicates severedroughts throughout most of the basin. This review provides a valuable starting point for further action towards amore climate-resilient and water-secure for sustainable environmental development and management over thebasin.

The use of metal nanoparticles as antibiotics for resistant pathogens has become a current topic of research. Biosyn-thesized nanoparticles are promising drugs as antibacterial agents by inhibiting bacteria from infectious diseases. Thisstudy aimed at the synthesis and characterization of silver nanoparticles (AgNPs) from AgNO 3 solution and Sida schim-periana Hochst. ex A. Rich leaves extract. The synthesized AgNPs were characterized by Fourier Transform Infrared (FTIR),Ultraviolet–Visible (UV–Vis) and X-ray diffraction (XRD) spectroscopic techniques and evaluated for antibacterial activi-ties against Gram-positive (Staphylococcus aureus and Staphylococcus epidermidis) and Gram-negative (Escherichia coliand Klebsiella Pneumonia) bacteria by the disc diffusion method. The result indicated an initial color change that wasobserved below 400 nm for the leaves extract and 429 nm for AgNPs in the UV–Vis band supporting the synthesis ofsilver nanoparticles. The FTIR peaks at 3447, 1638 and 1413 cm −1 predict the hydroxyl, carbonyl and unsaturated C–Cbonds, respectively, in the plant leaves extract. The XRD analysis showed that the synthesized AgNPs were crystalline innature and face-centered cubic (FCC) structure with an average particle size of 26.27 nm. Furthermore, the synthesizednanoparticles showed antimicrobial activity to both types of bacteria, more significant being on Gram-negative bacteria(E. coli). In conclusion, the leaves extract of Sida schimperiana Hochst. ex A. Rich plant contains bioactive molecules thatare used in the reduction and stabilization of AgNPs as potential antibacterial agents.Keywords: Biosynthesis · Phytochemicals · Antimicrobial resistance · Medicinal plant · Resistant pathogens

Abstract Preview:
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.

Increasing greenhouse gas (GHG) emissions and environmental issues have heightened the demandfor renewable energy sources (RES) and prompted a swift transition to electric vehicles (EVs) in thetransportation sector. This shift underscores the need to address the challenges of electricity supplyand continuity for electric vehicle charging stations (EVCS). This study aims to determine the mostsuitable hybrid systems to ensure the electricity supply to EVCSs in the Çukurova region of Adana,Turkey. Six different scenarios involving components such as photovoltaic (PV) panel, wind turbine(WT), biomass generators (BG), electrolyzer (Elz), hydrogen tank (HT), fuel cell (FC), batteries (Bat),inverter (Inv), and the grid were analyzed using HOMER Pro microgrid analysis tool version 3.14.2software. The optimization results indicated that the most feasible system was Scenario 4, comprisingthe PV, BG, Elz, HT, FC, Inv, and grid components. This scenario’s total net present cost (NPC) was$611,283.50, with a levelized cost of energy (LCOE) of $0.0215. The annual energy productionand consumption were 1,507,169 kWh and 1,420,714 kWh, respectively. The fact that the energygenerated from exceeds the energy sourced from the grid reduces the payback period of the system.These findings highlight the economic and sustainable potential of renewable hybrid systems forenhancing the performance of EVCS in solar-rich regions.Keywords: Energy cost efficiency, Renewable energy integration, Electric vehicle charging stations, Hybridsystems, Optimization, Energy sustainability
