Determinants of Community-Acquired Pneumonia Among Adults Patients Attending Debre Berhan University Hakim Gizaw Hospital, Northeast Ethiopia: A Case-Control Study

Background

Community-acquired pneumonia among adults remains an important cause of morbidity and mortality in both industrialized and developing countries, including Ethiopia. Moreover, despite the availability of the best clinical standards, morbidity and mortality from community-acquired pneumonia have not improved over the last few decades. Therefore, prompt assessment and correction of modifiable risk factors are crucial to reduce morbidity and mortality. However, there are limited data on the determinants of community-acquired pneumonia among adults in the current study area.

Purpose

This study aimed to identify the determinants of community-acquired pneumonia among adult patients visiting Debre Berhan University Hospital, Ethiopia, May 2023.

Methods

A hospital-based unmatched case-control study design was conducted to select 113 cases and 113 controls using a consecutive sampling technique. Using the SPSS version 25 software bi-variable and multivariable logistic regression analyses were performed to identify the determinants of community-acquired pneumonia. Adjusted odds ratios with 95% confidence intervals and p-values < 0.05 were used to assess the level of significance.

Results

In this study, recent history of common cold [AOR: 4.35, 95% CI: (2.22, 8.51)], recent history of toothache [AOR: 2.51, 95% CI: (1.18, 5.33)], and not brushing teeth regularly [AOR, 2.79; 95% CI: (1.32, 5.88)] were significantly associated with community-acquired pneumonia.

Conclusion

In this study, common cold, recent history of toothache, and lack of regular oral hygiene were significantly associated with community acquired pneumonia in adults. Therefore, health promotion of oral hygiene and the common cold is recommended to decrease the risk of pneumonia.

Completing the Continuum of Maternity Care and Associated Factors in Debre Berhan Town, Amhara, Ethiopia, 2020

Background

The continuum of maternity care is the continuity of maternal health care services that a woman practices antenatal care, skilled birth attendant, and postnatal care. Even though there are positive inclinations towards the continuum of maternity care, the problem is still significant. So, the purpose of this study was to assess the utilization of continuum maternity care and associated factors among women who gave birth in the last 12 months before the data collection period in Debre Berhan town.

Methods

A community-based cross-sectional study was conducted from February 17 to March 15/2020. The respondents were selected by using the cluster sampling technique. Face-to-face interview was used for data collection. EpiData software version 3.1 was used for data entry and exported to SPSS version 21 for further analysis. In multivariable logistic regression, a statistically significant association has declared a p-value <0.05.

Results

In this study, the proportion of women who completed the continuum of maternity care was 37.2% (95% CI: 33.4-41.1). Completing primary education (AOR: 2.73, 95% CI: 1.17-6.38), secondary education (AOR: 3.11, 95% CI: 1.32-7.31), college and above educational level (AOR: 4.15, 95% CI: 1.79-9.57), initiation of first ANC visit ≤16wks (AOR: 2.57, 95% CI: 1.41-4.68), knowing key pregnancy danger signs (AOR: 1.91, 95% CI: 1.15-3.19), and well prepared on birth and complication readiness (AOR: 1.59, 95% CI: 1.10-2.32) were found to positively increase the chance of completing maternity care in our study area.

Conclusion

Even if a higher proportion of mothers completed the continuum of maternity care in the study area than the finding at national level of 9.1% basing EDHS 2016 data, further interventions are mandatory to reach the acceptable level. Therefore, health promotion programs targeting mothers with no education and lower educational level are important to increase their awareness about the importance of completing all levels of maternity care, health education, and counseling regarding early initiation of ANC, pregnancy danger signs, and birth preparedness and complication readiness plan.

Signal protein-functionalized gold nanoparticles for nuclear targeting into osteosarcoma cells for use in radiosensitization experiments

The standard therapy for malignant primary bone tumors such as osteosarcoma involves major surgeries. For tumors located in difficult regions such as the pelvis, surgical intervention could lead to serious side effects for example loss of a limb and/or function, loss of bowel, bladder and sexual function as well as problems with wound healing and surgical complications. Therefore, exploring other approaches that can improve or complement current surgical techniques is important. Hence, sensitizing primary bone tumors to radiation could offer an additional strategy that could complement surgery and significantly improve survival and quality of life. Gold nanoparticles (AuNPs) have been shown to enhance radiosensitivity by increasing the local dose of radiation inside tumors. Therefore, the referred procedure of preparation and functionalization of gold nanoparticles may be used for investigation whether DNA repair inhibition in the presence of AuNPs leads to an effective radiosensitizing strategy for primary bone tumor cells and explore the mechanism of how this may be happening. In our work, we prepared gold nanoparticles and verified the relation between the size of the AuNPs and their uptake in tumor 143B cells and also investigated whether the optimal size of the AuNPs should not be smaller than the size of nuclear envelope pores (20-50 nm). Hence, two different AuNPs systems were prepared: the first one with AuNPs core size of about 5 nm (BS) and the second one with AuNPs core size of about 50 nm (ZA). For cellular AuNPs uptake enhancement, we functionalized the AuNPs with signaling peptides. For this purpose we prepared PEG-coated AuNPs functionalized with signal peptides for targeted transport into the cytoplasm (CPP) and into the cell nucleus (CPP + NLS). The toxicity of the AuNPs systems was assessed by MTS assay. We prepared stable functionalized AuNPs systems of both sizes. With the functionalizing of the AuNPs using signal peptides (CPP, NLS), the AuNPs penetrated into the cell nucleus. The referred procedure of preparation and functionalization of gold nanoparticles may be used for investigating inhibition of DNA repair in the presence of AuNPs and it could lead to new understanding in overcoming radioresistance in primary bone tumor cells.
