Triple-negative breast cancer (TNBC) is associated with an increased risk of early recurrence and distant metastasis, as well as the development of therapeutic resistance and poor prognosis. TNBC is characterized by a wide range of genetic, immunophenotypic, morphological, and clinical features. TNBC is coined to describe cancers that lack estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). As a result, hormonal or trastuzumab-based treatments are ineffective in TNBC patients. TNBCs are biologically aggressive, and despite some evidence that they respond to treatment better than other forms of breast cancer, the prognosis remains poor. This is attributed to a shorter disease-free interval in adjuvant and neoadjuvant settings, as well as a more aggressive metastatic course. TNBC has a lot of clinical ramifications. In terms of new treatment methods, TNBC has lagged behind other types of breast cancer. There are not many options for treating this form of breast cancer because it is progressive. Many effective treatments for most breast cancers block the growth-stimulating effects of ER, PR, and/or HER2, leaving TNBC with few choices. Finding new and effective treatment options for TNBC remains a critical clinical need. To develop more effective drugs, new experimental approaches must be tested in patients with TNBC.

Introduction: Availability and accessibility of a safe COVID-19 vaccine do not necessarily guarantee an effective means to mitigate the pandemic. However, the fragile hero’s or health care worker’s attitude toward the vaccine is of paramount importance to promote its acceptance. So, the current review aims to provide the latest assessment of healthcare workers’ attitudes toward the COVID-19 vaccination and its contributing factor worldwide. Methods: Peer-reviewed surveys in English indexed via an electronic database in Google Scholar, Science Direct and PubMed were systematically searched. The review was carried out per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA-2009) and registered on PROSPERO (CRD42021265534). Results: Originally 8039 articles were searched from three databases PubMed, Science direct, and Google scholar. Finally, 24 studies met the inclusion criteria and made the root for the estimates of the attitude of COVID -19 vaccinations. In about two-thirds of the studies, respondents showed a positive attitude (≥ 50%) toward COVID-19 vaccination. However, in about one-quarter of the studies, a negative attitude (< 50%) against vaccination was reported. Factors related to the attitude of healthcare workers toward COVID-19 vaccination include age, sex, profession, concerns about the safety of vaccines and fear of COVID-19, trust in the accuracy of the measures taken by the government, flu vaccination during the previous season, comorbid chronic illness, history of recommendation, and depression symptoms in the past week. Conclusion: Although most studies report that healthcare workers have a positive attitude toward COVID-19 vaccination, quite a few surveys mention negative attitudes towards the use of vaccines, which may reflect missed opportunities or challenges for the international efforts aimed at mitigating the pandemic. Still, we need to continue to make more efforts to change the attitudes of the uncertain healthcare workers to increase the uptake of the vaccine and deal with the multi-faceted impact of infection.

Acute poisoning is a common reason for emergency department visit and hospitalization worldwide with major morbidity and mortality. The burden of poisoning exposures in Africa is a significant public health concern, but only 10 of 58 countries have poisons information centers (PICs). The primary intention of our current review is to explore and summarize the published evidence on the patterns and epidemiology of poisoning in Ethiopia. PubMed and Scopus were searched for primary, case series and human studies for publications from inception to July 2017. A manual search for additional relevant studies using references from retrieved articles was also performed. Only studies that reported acute poisoning in both pediatric and adult patients were included. From the screened articles, data were extracted for baseline characteristics and relevant end points such as case fatality rate, time for health institution presentation and length of hospital stay. Initial entry and search resulted in the retrieval of 332 articles. Finally, 9 studies comprised of 4763 participants were included in this current review. In 78% of the studies included in this review, acute poisoning is reported to be more prevalent in females. Acute poisoning was revealed to be prevalent in less than 30 years old. Organophosphates and household cleaning agents were the predominant agents of acute poisoning. Intentional poisoning was identified responsible for the majority of acute poisoning cases and factors such as psychiatric problems, and quarrel were identified as the underlying reasons for poisoning. Time of presentation to health institution after poisoning, length of hospital stay and case fatality rate were reported and lies in the ranges between 0.2 h–24 h, 0.5 days–17.7 days and 0–14.8%, respectively. The occurrence of acute poisoning was higher in females and common in less than 30 years of age, making this a real public health burden in Ethiopia. Psychiatric problems, quarrel and substance abuse were identified as the most common reasons for acute poisoning. Awareness creation how to handle chemicals and prescribed drugs and psychiatric consultations should be in place for the community.

Diabetic foot ulcer is one of the complications of diabetes mellitus. The diabetic patients with foot infections especially gangrene require long-term hospitalization and carry the risk of limb amputation. Despite these challenges, there are a scarce studies done on risk factors and no finding on outcomes of diabetic foot ulcers in Ethiopia. A prospective observational study was conducted among diabetes patients with diabetic foot ulcer at Nekemte referral hospital from March 15 to June 15, 2018. Of the 115 diabetes foot ulcer patients admitted to Nekemte referral hospital, 64(55.65%) were males and the mean age of participants was 44.4 ± 14.7 years. Fifty-eight (50.43%) of the patients had chronic health problems and 56(48.69%) had diabetic complications. Of patients with complications, 35(30.43%) were undergone amputations. Diabetic foot ulcer grade ≥4 (AOR = 1.7; 95% CI: 1.604, 4.789), inappropriate antibiotics use (AOR = 2.526; 95% CI: 1.767, 8.314), overweight (AOR = 2.767; 95% CI: 1.827, 9.252), obesity (AOR = 3.020; 95% CI: 2.556, 16.397), poor blood glucose control (AOR = 2.592; 95% CI: 1.937, 7.168) and neuropathy (AOR = 1.565; 95% CI: 1.508, 4.822) were predictors of amputation up on multivariable logistic regression analysis. Blood glucose level, higher body mass index, inappropriate antibiotics use, neuropathy and advanced grade of diabetic foot ulcer were independent predictors of amputation. Thus, special emphasis for patients having neuropathy and advanced grade of diabetic foot ulcer as well as weight reduction, managing hyperglycaemia, and appropriate antibiotics prescription practice would decrease untoward effects of diabetic foot ulcer.

Introduction: Coronavirus disease 2019 is a pandemic disease, requiring persons around the world to take immediate action to reduce the risk of infection. This study was aimed to summarize the patterns and determinants of coronavirus disease 2019 knowledge, attitude, and practice among general populations and health workers. Methods: A cross-sectional study from PubMed, HINARI, and Scopus were searched from March 16 to July 30, 2020. The review was done in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses–2009. Result: We found 56 articles upon the initial search. Finally, 21 studies were filtered to be studied in this systematic review. Overall, the majority of the articles that were previously published had good knowledge about coronavirus disease 2019 that lies in the ranges from 40% to 99.5%. A good attitude lies in the ranges from 70% to 97.1%. Among impact of coronavirus disease 2019 on mental health, only anxiety was reported that ranges from 24.6% to 96.3%. We found the variable practice towards combating coronavirus disease 2019. Several factors were associated with poor knowledge, attitudes, and practice skills regarding the pandemic of coronavirus disease 2019 such as level of education, occupation, income, gender, age, residence, work experience, religion, having media, marital status, and race. Conclusion: The majority of the articles that were previously published had found good knowledge and attitude about coronavirus disease 2019 and variable reports for practice to combat the disease. Most of them were severely worried about the disease. Therefore, the mental effect of the coronavirus disease 2019 should be studied at large, and every country should implement the strategy to combat the disease to increase the level of practice.

Objectives: Insufficient nutrition can predisposes women to infection, pregnancy losses, preeclampsia and anaemia as well birth of underweight baby whose survival is threatened. Therefore, this study was aimed to assess pregnant mothers’ nutrition knowledge, attitude, practice and associated factors. Methods: A multicenter cross-sectional study was conducted among 378 participants who were selected using a systematic random sampling technique. Quantitative data were collected using a structured and interviewer-administered questionnaire, which consisted of questions on sociodemographic features, obstetrics characteristics and pregnant women’s nutrition knowledge, attitude and practice. Data entry and analysis were done using Statistical Package for the Social Sciences statistical version 23. Binary logistic regression analysis was done to identify associated factors. All variables with p-value of < 0.23 in bivariate analysis were included in multivariate analysis, and finally, statistical significance was declared at p-value < 0.05 with 95% confidence interval. Result: From 378 women participated, a total of 231 (61.1%) respondents were in age range of 25–34 years. About 148 (39.1%) of women were not knowledgeable, 153 (40.5%) had an unfavourable attitude, and 47.7% had poor dietary practice. Knowledge (adjusted odds ratio = 4.5; 95% confidence interval: 2.88, 10.06, p = 0.03), attitude (adjusted odds ratio = 3.6; 95% confidence interval: 2.43, 6.66, p = 0.04) and practice (adjusted odds ratio = 3.6; 95% confidence interval: 2.43, 6.66, p = 0.036) were all significantly associated with maternal education. Regarding their occupation, merchant women were seven times (adjusted odds ratio = 7.02; 95% confidence interval: 2.88, 17.09, p = 0.01) more likely to have knowledge and government employees were six times (adjusted odds ratio = 6.05; 95% confidence interval: 3.58, 13.05, p = 0.04) more likely to be knowable than housewives. Moreover, multiparous women were 4.77 times (adjusted odds ratio = 4.77; 95% confidence interval: 1.15, 8.66, p = 0.002) more likely to be knowledgeable compared to primigravida women. Monthly income was also associated to attitude (adjusted odds ratio = 0.45, 95% confidence interval: 0.10, 1.66, p = 0.03). Women who had a favourable attitude were five times (adjusted odds ratio = 5.25; 95% confidence interval: 2.36, 9.62, p = 0.04) more likely to have good nutritional practices during pregnancy. Conclusion: Pregnant women’s knowledge, attitude and practice towards nutrition in this area were low. The educational status of women was associated with knowledge; attitude and practice. Likewise, occupation and parity were associated with knowledge; and attitude was also found to be a determinant factor of nutritional practice. Therefore, community nutritional education and antenatal nutritional counselling need to be strengthened in the area.
