Antibiotic resistance and the COVID-19 pandemic: A dual crisis with complex challenges in LMICs.

Background and Aims: Antimicrobial resistance (AMR), a global health crisis of mounting urgency, has been further complicated by the ongoing COVID-19 pandemic. The intricate relationship between these two phenomena is especially pronounced in low- and middle-income countries (LMICs) due to the distinct obstacles encountered by their healthcare systems and policy structures. This study aims to explore the complex challenges arising from the coexistence of these two crises in LMICs and proffer specific recommendations for holistic management. Methods: An exhaustive bibliographic survey was executed, employing search queries in specialized databases such as PubMed, SCOPUS, and Web of Science's SCI-EXPANDED index. The timeframe for the literature search extended from January 2020 to January 2023. The search strategy employed key terms including antibiotic resistance, AMR, COVID-19 pandemic, low- and middle-income countries, SARS-CoV-2, and LMICs. Results: The pandemic has aggravated various drivers of AMR in LMICs, including limited capabilities, weak frameworks, and socioeconomic factors. New challenges have emerged, such as disruptions in the antibiotic supply chain and an increased risk of healthcare-associated infections. The interaction between these drivers presents a complex problem that demands a coordinated response. Specific recommendations include strengthening health systems, funding research and innovation, and enhancing infection prevention control measures. Conclusion: The coexistence of AMR and the COVID-19 pandemic in LMICs demands an integrated approach involving multiple stakeholders. Emphasis must be placed on constructing aligned regulatory frameworks, nurturing regional collaborations, and focusing on accessible therapeutic options. The study underscores the necessity for actionable strategies to achieve sustainable access to clean water and sanitation and also highlights the importance of long-term planning, funding, and specialized expertise in emerging modalities like phage therapy.

Health-related quality of life associated with different cervical cancer therapies received by patients in two Nigerian tertiary hospitals.

Background: There are important consequences from cervical cancer (CC) disease and its treatment among survivors, especially the impact on quality of life (QoL). Objective: To evaluate the health-related QoL associated with different CC therapies received by patients in two Nigerian tertiary hospitals. Methods: This study employed a prospective longitudinal design. It was conducted at Usmanu Danfodiyo University Teaching Hospital, Sokoto and Ahmadu Bello University Teaching Hospital Zaria, North-Western Nigeria. Data of all the 157 eligible CC patients were collected at baseline and after therapy. Data analysis was done with appropriate descriptive and inferential statistics using SPSS V. 20 for windows. P<0.05 was considered statistically significant. Results: Chemotherapy (CT) was the major therapy option received by 78(49.7%) of the patients. Patients who received chemoradiation therapy (CRT) and adjuvant chemotherapy (CTS) had the highest increase in mean overall health-related QoL of 0.138 (t=8.456, p<0.001) and 0.138 (t=6.489, p<0.001) higher than their respective baseline scores. Patients who received CT had the least increase in mean overall health-related QoL of 0.095 (t=4.574, p<0.001) from baseline. Conclusion: Chemoradiation therapy and adjuvant chemotherapy were associated with highest increase in mean overall health-related QoL. Chemotherapy was associated with the least increase in mean overall health-related QoL.

Combating the menace of antimicrobial resistance in Africa: a review on stewardship, surveillance and diagnostic strategies.

The emergence of antibiotic-resistant pathogens has threatened not only our ability to deal with common infectious diseases but also the management of life-threatening complications. Antimicrobial resistance (AMR) remains a significant threat in both industrialized and developing countries alike. In Africa, though, poor clinical care, indiscriminate antibiotic use, lack of robust AMR surveillance programs, lack of proper regulations and the burden of communicable diseases are factors aggravating the problem of AMR. In order to effectively address the challenge of AMR, antimicrobial stewardship programs, solid AMR surveillance systems to monitor the trend of resistance, as well as robust, affordable and rapid diagnostic tools which generate data that informs decision-making, have been demonstrated to be effective. However, we have identified a significant knowledge gap in the area of the application of fast and affordable diagnostic tools, surveillance, and stewardship programs in Africa. Therefore, we set out to provide up-to-date information in these areas. We discussed available hospital-based stewardship initiatives in addition to the role of governmental and non-governmental organizations. Finally, we have reviewed the application of various phenotypic and molecular AMR detection tools in both research and routine laboratory settings in Africa, deployment challenges and the efficiency of these methods.

Financial management and perioperative leadership in the ambulatory setting journal title: Best practice in clinical research.

A large portion of US healthcare is ambulatory. Strong leadership is vital for the safety and efficiency of perioperative patients in this setting. Good leaders communicate respectfully and openly and ensure effective systems in the delivery of high-level healthcare. In general, to promote patient safety and treatment efficacy, ambulatory care leaders must improve communication. Effective administration is unattainable without leadership and communication in an operating room. When considering outpatient perioperative therapy, it is equally crucial to consider medical costs. Given the unsustainable rate of healthcare spending growth, all attempts to improve our present systems are necessary. Ambulatory care facilities must utilize data regarding resource consumption to be financially viable related to escalating expenses. The present review describes perioperative and financial leadership in the ambulatory setting, effective systems, and relevant clinical strategies.

Development and reliability testing of a cervical cancer patients knowledge and practice of self-care management of treatment-related adverse events questionnaire.

INTRODUCTION: Cervical cancer (CC) treatment-related adverse events (AEs) were found to be among the major reasons for treatments delays and medication non-adherence. Knowledge and practice of self-care management of these AEs are therefore needed to complement the pharmacotherapeutic interventions. Instruments for assessing CC patients' knowledge and practice of self-care management of treatment-related Adverse Events (AEs) are lacking. Hence, the rational for this study. METHODS: A prospective, cross-sectional study was conducted on CC patients receiving chemotherapy, radiotherapy or both, with or without surgery in Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto, a tertiary hospital in North-Western Nigeria. A panel of 14 experts judged the content validity of the items initially selected. Purposive sampling technique was used, 31 CC patients were recruited and interviewed for the questionnaire pre-testing. Descriptive statistics and psychometric analysis were conducted using SPSS Version 20.0 for Windows. A Cronbach's alpha coefficient ≥0.70 was considered acceptable. RESULTS: A 12-domain questionnaire instrument was developed. Eight (57.1%) of the expert panelists rated the questions' items as "Very good for the study" and none of them rated any of the content "not relevant for the study". The reliability studies showed that the overall knowledge and practice questions response rates were 71.0% and 77.4% and Cronbach's alpha (α) values were 0.956 and 0.913, respectively. CONCLUSION: A reliable, 12-domain cervical cancer patients' knowledge and practice of self-care management of treatment-related adverse events questionnaire was developed. Further research on the psychometric qualities of the instrument is needed.

Emerging Use of Public-Private Partnerships in Public Radiotherapy Facilities in Nigeria.

PURPOSE: Radiotherapy (RT) treatment at public hospitals in Nigeria is often interrupted by prolonged periods of machine breakdown because of insufficient funds for maintenance and repair. These delays have prompted the uptake of public-private partnerships (PPPs) to acquire and maintain RT equipment. This study aimed to understand Nigeria's current RT capacity and the impact of PPPs on RT availability and cost. METHODS: Eleven radiation oncologists, each representing one of the 11 RT centers in Nigeria (eight public and three private), were invited to complete a survey on the type, status, acquisition, and maintenance plan of existing RT equipment, cost incurred by patients for external-beam radiation (EBRT) and brachytherapy treatment, and number of patients treated per year on each machine. Type and status of equipment at nonresponding facilities were obtained through literature review and confirmed with the facility. RESULTS: A total of eight (81%) respondents completed the survey, all representing public centers, three of which reported PPP use. They reported 11 megavoltage units in total (seven linear accelerators [LINACs] and four Cobalt-60s) and 10 brachytherapy afterloaders. Of those, 57% (4/7) of the LINACs, 100% (4/4) of the Cobalt-60s, and 63% (7/11) of the afterloaders were in clinical use. All commissioned equipment supported by PPPs (three LINACs and one afterloader) were in operation. The public EBRT equipment were nonfunctional 35% of the year (resulting in 60% fewer patients treated per year). The PPP EBRT and afterloaders did not experience any periods of breakdown, but PPP costs were 338% higher than public equipment. CONCLUSION: This study characterizes the use of PPP as a more reliable method of RT delivery in Nigeria, albeit at higher costs.

Prognostic significance of BIRC7/Livin, Bcl-2, p53, Annexin V, PD-L1, DARC, MSH2 and PMS2 in colorectal cancer treated with FOLFOX chemotherapy with or without aspirin.

Evasion of apoptosis is associated with treatment resistance and metastasis in colorectal cancer (CRC). Various cellular processes are associated with evasion of apoptosis. These include overexpression of pro-apoptotic proteins (including p53 and PD-L1), anti-apoptotic proteins (BIRC7/Livin and Bcl-2), chemokine receptors (including DARC), and dysregulation of DNA mismatch repair proteins (including MSH2 and PMS2). The aim of this study was to determine the effect of folinic acid, 5-FU and oxaliplatin (FOLFOX) as a single agent and aspirin plus FOLFOX in various combinations on the aforementioned proteins in human CRC, SW480 cell line and rat models of N-Methyl-N-Nitrosourea (NMU)-induced CRC. In addition, effects of the NMU-induced CRC and chemotherapeutic regimens on haematological and biochemical parameters in the rat models were studied. Immunohistochemistry, immunofluorescence and immunoblot techniques were used to study the expression pattern of the related proteins in the human CRC cells pre- and post-treatment. Double contrast barium enema, post-mortem examination and histological analyses were used to confirm tumour growth and the effect of the treatment in vivo in rat models. Notably, we found in human mucinous CRC, a significant increase in expression of the BIRC7/Livin post-FOLFOX treatment compared with pre-treatment (p = 0.0001). This increase provides new insights into the prognostic role of BIRC7/Livin in evasion of apoptosis and facilitation of treatment resistance, local recurrence and metastasis particularly among mucinous CRCs post-FOLFOX chemotherapy. These poor prognostic features in the CRC may be further compounded by the significant suppression of DARC, PD-L1, PMS2 and overexpression of MSH2 and anti-apoptotic Bcl-2 and p53 proteins observed in our study (p < 0.05). Importantly, we found a significant reduction in expression of BIRC7/Livin and reactivation of DARC and PD-L1 with a surge in Annexin V expression in rat models of CRC cells post-treatment with a sequential dose of aspirin plus FOLFOX compared with other treatments in vivo (p <0.05). The mechanistic rational of these effects underscores the importance of expanded concept of possible aspirin combination therapy with FOLFOX sequentially in future CRC management. Validation of our findings through randomized clinical trials of aspirin plus FOLFOX sequentially in patients with CRC is therefore warranted.

Potential of Using Ginger Essential Oils-Based Nanotechnology to Control Tropical Plant Diseases.

Essential oils (EOs) have gained a renewed interest in many disciplines such as plant disease control and medicine. This review discusses the components of ginger EOs, their mode of action, and their potential nanotechnology applications in controlling tropical plant diseases. Gas chromatography-mass spectroscopy (GC-MS), high-performance liquid chromatography, and headspace procedures are commonly used to detect and profile their chemical compositions EOs in ginger. The ginger EOs are composed of monoterpenes (transcaryophyllene, camphene, geranial, eucalyptol, and neral) and sesquiterpene hydrocarbons (α-zingiberene, ar-curcumene, ß-bisabolene, and ß-sesquiphellandrene). GC-MS analysis of the EOs revealed many compounds but few compounds were revealed using the headspace approach. The EOs have a wide range of activities against many phytopathogens. EOs mode of action affects both the pathogen cell's external envelope and internal structures. The problems associated with solubility and stability of EOs had prompted the use nanotechnology such as nanoemulsions. The use of nanoemulsion to increase efficiency and supply of EOs to control plant diseases control was discussed in this present paper. The findings of this review paper may accelerate the effective use of ginger EOs in controlling tropical plant diseases.

Patterns of Early-Onset Colorectal Cancer Among Nigerians and African Americans.

PURPOSE: Colorectal cancer (CRC) incidence rates are increasing among individuals < 50 years of age (early-onset CRC) globally with causes unknown. Racial/ethnic disparities in early-onset CRC have also grown more pronounced, because Black individuals have higher early-onset CRC incidence and poorer survival compared with White individuals. We describe the prevalence and burden of early-onset CRC among Africans in Nigeria and African Americans (AAs) in the United States. PATIENTS AND METHODS: We identified Black individuals diagnosed with a first primary CRC ages 18 to 49 years between 1989 and 2017 at Ahmadu Bello University Teaching Hospital in Zaria, Nigeria (Nigerians), and in the United States (AAs) using the National Institutes of Health/National Cancer Institute's SEER program of cancer registries. Multivariable logistic regression models were used to investigate clinical and demographic differences between Nigerians and AAs with early-onset CRC, adjusted for age, sex, tumor site, and histology. RESULTS: A total of 5,019 Black individuals were diagnosed with early-onset CRC over the study period (379 Nigerians; 4,640 AAs). Overall, approximately one third of young Black patients were diagnosed with rectal tumors (35.8%). Nigerian individuals with early-onset CRC were eight-fold more likely to be diagnosed with rectal tumors (odds ratio [OR], 8.14; 95% CI, 6.23 to 10.62; P < .0001) and more likely to be diagnosed at younger ages (OR, 0.87; 95% CI, 0.86 to 0.89; P < .0001) compared with young African Americans in adjusted models. CONCLUSION: Compared with AA individuals diagnosed with early-onset CRC, Nigerian individuals harbor distinct features of early-onset CRC. Additional investigation of the histopathologic and biologic heterogeneity of early-onset CRCs among Black individuals is critical for understanding racial disparities in susceptibility and outcomes, which may have implications for tailored early-onset CRC prevention, detection, and treatment strategies.

Financial Burden of Cancer on Patients Treated at a Tertiary Health Facility in South West Nigeria.

Background: Cancer is a growing health concern in the world. The financial burden of cancer affects not only cancer patients and their families, but also the society as a whole. In Nigeria there is a dearth of information about the financial burden of cancer on patients. Hence, there is need to estimate the cost of cancer treatment and to show the resources being allocated to the problem. Objectives: The aim of this study was to estimate the financial burden of cancer on patients treated at a tertiary heath facility in South West Nigeria. Materials and Methods: The study was a cross-sectional study and patients were interviewed using a set of questionnaires that addresses sociodemographic and economic questions involving medical and nonmedical costs (direct medical costs). Data Analysis: Data obtained were analyzed using the Statistical Package for Social Sciences (SPSS), version 21.0. Descriptive statistics such as frequencies (%), mean, standard deviation, median, range and P-value were used to highlight important and relevant features of the data. For ease of analysis some of the variables such as sociodemographic, medical, and nonmedical costs were grouped or categorized. Results: Two hundred and twenty cancer patients participated in the study. The mean age of the patients was 54.1 (standard deviation [SD] = 13.4) years and majority were females (81.4%). Approximately one-third of the respondents were those with breast (35.9%) and cervical (35.5%) cancers, respectively. Majority perceived financial burden as a result of cancer to be significant (82.7%).The mean annual income of patients was $5,548.7(SD = $7,245.4). The main sources of income for their treatments were from their children (26.8%). The mean total cost incurred by patients with cancer was $5306.9 (SD = $5045.7), with medical costs accounting for the highest percentage $3889.4 (SD = $4372.9); 73.0% and nonmedical costs of $1417.5 (SD = $1085.6); 27.0%. Patients with colorectal cancer incurred the highest cost, whereas cervical cancer patients incurred the least cost. Conclusion: Financing cancer management is a major challenge for both patients and their caregivers. Cancer care also results in a loss of economic income available to the community/country.

Knowledge, risk perception, and attitudes of Nigerian dentists toward covid-19: pilot study

COVID-19 is a highly communicable viral respiratory infectious disease with potential life-threatening capabilities. As caregivers, the healthcare practitioners are at risk of contracting disease.Aim: To explore the knowledge, risk perception, and attitudes of Nigerian dentists toward COVID-19.Material and Methods: This pilot study was a survey of 69 dentists in Nigeria using an e-questionnaire. Collected data was analysed using SPSS version 22 software. Results: The majority (62.3%) of the respondents were within the age range of 20 ­ 29 years, 50.7% were males. All of the respondents had heard of COVID-19 and the most common source of information on the disease was the social media. They all knew about the cause of COVID-19 and also that the virus can be transmitted through respiratory droplets. The majority (≥76%) of them knew about the incubation period, symptoms, and safety measures to be adopted in curbing COVID-19 transmission. They all perceived COVID-19 to be highly contagious and a potential cause of respiratory failure. Amidst other findings, they all felt that it is not safe to see a COVID-19 patient without personal protective gears. Only 4 (5.8%) agreed that HIV/AIDS is better than COVID-19 by far while only 65.2% ([29+16]/69) of them indicated that they would like to help people that are infected with COVID-19. Conclusion: This study suggests that Nigerian dentists have sufficient knowledge and high level of risk perception of COVID19. Despite this high knowledge level, some few of them are still afraid of associating with people having the disease.

From paper maps to digital maps: enhancing routine immunisation microplanning in Northern Nigeria.

Geographical information systems (GIS) can be effective decision-support tools. In this paper, we detail a GIS approach implemented by the Bauchi and Sokoto state primary healthcare development agencies in Nigeria to generate and convert routine immunisation (RI) paper maps to digital maps for microplanning. The process involved three stages: primary and secondary data collection and reconciliation, geospatial data processing and analysis, and production and validation of maps. The data collection and reconciliation stage identified a number of challenges with secondary data sources, including the need to standardise and reconcile health facility and settlement names. The study team was unable to apply population estimates generated from the Global Polio Eradication Initiative to RI planning because operational boundaries for polio activities are defined differently from RI activities. Application of open-source GIS software enabled the combination of multiple datasets and analysis of geospatial data to calculate catchment areas for primary health centres (PHCs) and assign vaccination strategies to communities. The activity resulted in the development of PHC catchment area digital maps, and captured next steps and lessons learnt for RI microplanning in the two states. While the digital maps provided input into the microplanning process, more work is needed to build capacity, standardise processes and ensure the quality of data used to generate the maps. RI service providers and communities must be engaged in the process to validate, understand the data, the contextual factors that influence decisions about which vaccination strategies RI microplans include and how resources are allocated.

Human immunodeficiency virus seroprevalence in patients with invasive cervical cancer in Zaria, North-Western Nigeria.

BACKGROUND: Cervical cancer is the commonest gynecological malignancy in our environment and is an Acquired Immuno-Deficiency Syndrome (AIDS)-associated malignancy. Documented data on the Human Immune-deficiency Virus (HIV) seroprevalence among patients with cervical cancer in our environment are scarce. OBJECTIVE: The aim of this study is to determine the prevalence of HIV infection in women with cancer of the cervix. STUDY DESIGN: The work is a descriptive survey by design, concentrating in frequency of occurrences of prevalence of the dissease in either cases for a number of years retrospectively carried out at the Radiotherapy and Oncology Centre of Ahmadu Bello University Teaching Hospital (ABUTH) Zaria. SETTING: The study was carried out at the Radiotherapy and Oncology Centre of ABUTH, Zaria. MATERIALS AND METHODS: A 5 years retrospective review of patients with histologically-proven cancer of the cervix seen in the Radiotherapy and Oncology Centre, ABUTH, Zaria, North-Western Nigeria was undertaken. Data such as age, clinical stage of disease and HIV seropositivity at presentation were retrieved from the case files. Data analysis was done using the SPSS statistical package version IBM 23 and results presented in frequencies and percentages and charts for graphical presentation. RESULTS: A total of 1,639 patients seen over a period of 5 years were reviewed. The age range of both groups of patients was from 28 years to 92 years with a mean age of 50.5 years. One thousand five hundred and seventy-three of the patients (96%) were seronegative to the HIV tests while 66 (4%) were seropositive. The age range of the seropositive patients was 28 - 49 years with a mean age of 38.1 years. Their peak age at presentation was 30 - 39 years. Similarly, the age range of the seronegative patients was 30 - 92 years with a peak at 40-49 years. 51 (89.5%) of the HIV seropositive patients presented with advanced clinical stage disease, i.e, International Federation of Obstetrics and Gynecology (FIGO) stage 2B and above. 1,363 (93%) of the HIV seronegative patients presented with FIGO 2B disease and above, both scenario illustrating the general trend of late presentation of cancer patients to hospital in our environment. CONCLUSION: The study shows that the prevalence of HIV infection among cervical cancer patients is low in Zaria, with earlier age of development of cervical cancer among HIV seropositive patients compared to HIV seronegative counterparts. Both group of patients present with cervical cancer at an advanced stage. More studies therefore needed to be done to identify the predisposing factors to the high incidence of invasive cervical cancer in our environment and introduction of cervical cancer screening at an earlier age among HIV seropositive patients.

Management and outcomes of male breast cancer in zaria, Nigeria.

Male breast cancer is an uncommon disease accounting for only 1% of all breast cancers. We present the evaluation, treatment and outcome of male patients seen with breast cancer in our institution. Male patients that had histological diagnosis of breast cancer from 2001 to 2010 were retrospectively evaluated. After evaluation patients were treated with modified radical mastectomy. Combination chemotherapy was given to patients with positive axillary lymph nodes. Radiotherapy and hormonal therapy were also employed. There were 57 male patients with breast cancer which accounted for 9% of all breast cancers seen during the study period. Their mean age was 59 ± 2.3 years. The mean tumor diameter was 13 ± 2.5 cm. Fifty three (93%) patients presented with advanced disease including 15 with distant metastasis. Four patients with stage II disease were treated with modified radical mastectomy, chemotherapy and tamoxifen. Of the 30 patients with sage III disease that had modified radical mastectomy, complete axillary clearance and tumor free margins were achieved in 25. Overall 21 (36.8%) patients were tumor free at one year. Overall 5-year survival was 22.8%. In conclusion, male patients with breast cancer present with advanced disease which is associated with poor outcome of treatment.

Docetaxel chemotherapy in the management of advanced and metastatic breast cancer in Nigerians a pilot study

The aim of this study was to assess whether introduction of Docetaxel into the management will improve palliation of symptoms; quality of life; response rate and probably survival in breast cancer patients. A total of 19 patients referred from different medical centers in Nigeria were entered into the study. The age range was 25 to 52 years with a median of 34 years. The sex incidence was 18 females; 1 male. There were 7 patients in stage III and the duration of median response was 30 months. There were 12 patients in stage IV. Out of these 3 patients with brain metastasis had median response of 4 months. 4 patients with liver metastasis average duration of response was 22 months. 5 patients with pulmonary metastasis average duration of response was 20 months. In all; 16; out of the 19 patients (84
