Serum ferritin level and associated factors among uncontrolled adult type II diabetic follow-up patients: comparative based cross-sectional study.

BACKGROUND: Uncontrolled type 2 diabetes mellitus (UT2DM) and its associated consequences nowadays have been a global health crisis, especially for adults. Iron has the property to oxidize and reduce reversibly, which is necessary for metabolic processes and excess accumulation of iron indicated by serum ferritin levels could have a significant impact on the pathophysiology of T2DM via generation of reactive oxygen species (ROS). However, no conclusive evidence existed about the association of serum ferritin with the state of glycemic control status. Therefore, this study aimed to evaluate serum ferritin levels and associated factors in uncontrolled T2DM patients and compare them with those of controlled T2DM and non-diabetic control groups. METHODS: A hospital-based comparative cross-sectional study was conducted among conveniently selected 156 study participants, who were categorized into three equal groups of uncontrolled T2DM, controlled T2DM, and non-diabetic control groups from October 2 to December 29, 2023 at St. Paul's Hospital Millennium Medical College. A pre-tested structured questionnaire was used to collect socio-demographic and diabetes-related information. The laboratory tests were done using an automated chemistry analyzer and IBM-SPSS statistical software (version-27) was utilized for data entry and analysis with a significance level of p < 0.05. RESULT: The mean serum ferritin level was noticeably higher in uncontrolled T2DM patients as compared to controlled T2DM and control groups (p < 0.001). It was significantly correlated with HbA1c [r = 0.457, p < 0.001], fasting blood sugar (FBs) [r = 0.386, p < 0.001], serum iron [r = 0.430, p < 0.001], and systolic blood pressure (SBP) [r = 0.195, p = 0.047] in T2DM patients. A multivariate logistic regression model revealed that a rise in HbA1c (AOR = 3.67, 95% CI(1.50-8.98), serum iron (AOR = 1.02, 95% CI(1.01-1.04), male gender (AOR = 0.16, 95% CI(0.05-0.57) and being on oral hypoglycemic agent (OHA) monotherapy (AOR = 0.26, 95% CI(0.07-0.95) were key associated factors for the elevated serum ferritin among T2DM patients. CONCLUSION: The present study demonstrated that T2DM patients had elevated serum ferritin levels which might be related to the existence of long-term hyperglycaemia and that serum ferritin had a significant positive association with HbA1c and FBs, implying that it could be used as an additional biomarker to predict uncontrolled T2DM patients.

Continuing professional development (CPD) training needs assessment for medical laboratory professionals in Ethiopia.

BACKGROUND: Continuing professional development (CPD) is required for health workers in practice to update knowledge and skills regularly to match the changing complexity of healthcare needs. The objective of this study was to identify the training needs of Medical Laboratory professionals in Ethiopia. METHODS: A total of 457 medical laboratory professionals from five regions and two city administrations were involved in the study. Data were collected from August 02 to 21, 2021 with structured self-administered online tool with five-point Likert scale. The tool had consent, demography, cross-cutting issues, and main activity area specific to medical laboratory. RESULTS: Majority of the participants were male (80.1%). Participants from Amhara region 110 (24.1%) were the largest groups in the survey followed by Oromia 105 (23%) and Addis Ababa 101 (22.1%). The study participants comprised 54.7% with a bachelor's degree, 31.3% with a diploma (associate degree), and 14% with a master's degree. The participants had varying years of service, ranging from less than one year to over 10 years of experience. Most of the participants work as generalists (24.1%) followed by working in microbiology (17.5%) and parasitology (16%). The majority (96.9%) were working in a public sector or training institutions and the rest were employed in the private sector. Our study showed that the three most important topics selected for training in the cross-cutting health issues were health and emerging technology, computer skills and medico-legal issues. Topics under microbiology, clinical chemistry and molecular diagnostics were selected as the most preferred technical areas for training. Participants have also selected priority topics under research skill and pathophysiology. When the laboratory specific issues were regrouped based on areas of application as technical competence, research skill and pathophysiology, thirteen topics under technical competence, four topics under research skill and three topics under pathophysiology were picked as priority areas. CONCLUSION: In conclusion, our study identified that CPD programs should focus on topics that address technical competence in microbiology, clinical chemistry and molecular diagnostics. Additionally competencies in research skill and updating knowledge in pathophysiology should also receive due attention in designing trainings.

Epidemiology and Multidrug Resistance of Pseudomonas aeruginosa and Acinetobacter baumanni Isolated from Clinical Samples in Ethiopia.

Background: A. baumannii and P. aeruginosa are important nosocomial pathogens in health-care settings. Both are intrinsically resistant to many drugs and are able to become resistant to the virtually most antimicrobial agents. An increasing prevalence of infections caused by multidrug-resistant isolates has been reported in many countries. Methods: An institutional-based cross-sectional five-year retrospective study was conducted to assess the antimicrobial resistance trend of P. aeruginosa and A. baumani. 893 A. baumani and 729 P. aeruginosa isolates were included in the study. Conventional method was used for identification and antimicrobial susceptibility was determined by Kirby-Bauer disc-diffusion method. The isolates were from suspected bloodstream infections, wound infections, urinary tract, or surgical site nosocomial infections. Socio-demographic and other variables of interest were collected using a structured check list from a patient record data. Data were analyzed using SPSS version 26 software. P value <0.05 was considered statistically significant. Results: A total of 1622 A. baumanii and P. aeruginosa were isolated from various clinical specimens recorded from the year 2017-2021. Out of which A. baumanni was 893 (60.6%) and P. aeruginosa was 729 (39.4%). Blood was the major source of the isolates (18.3%), followed by urine (16%), and tracheal aspirate (10.6%). Antimicrobial resistance among A. baumanni over the five years were; ampicillin (86% to 92%), ceftriaxone (66.7% to 82.2%), and ciprofloxacin (58.5% to 66.7%). In P. aeruginosa a significant increase in resistance was seen from 2017 to 2021 to Amoxicillin-clavulanate (74.1% to 84.2%), chloramphenicol (62% to 81.9%), and gentamicin (40% to 44.8%). Conclusion: A five-year antimicrobial resistance trend analysis of A. baumanni and P. aeruginosa showed increasing multi drug resistance and resistance to highly potent antimicrobial agents in Ethiopia. It should be addressed with infection control measures, surveillance, and alternative new therapeutic strategies to circumvent the spread of multi-drug resistance.

Preceptors training need assessment for medical laboratory professional clinical education programs in Ethiopia.

BACKGROUND: Health Workforce Improvement Program and professional associations recognized the need for a formalized method of providing academic education that would improve how preceptors teach and assess student. Thus, this study aimed to assess training needs of preceptors for Medical Laboratory Science clinical practicum education programs in Ethiopia. METHODS: A cross-sectional survey design was implemented in targeted health facility throughout the country to assess academic educational needs of preceptors for Medical Laboratory clinical practicum education programs. The study participants were conveniently selected practicing health professionals who formally or informally nominated as a clinical trainer or acts as clinical trainer giving practical training to the student in the targeted practice setting. An adapted structured questionnaire modified to local context was used to conduct the survey and the perceived competency assessment used five scale of measurement (Not capable, Beginner, Advanced beginner, Competent, Proficient). The frequency was presented using tables and figures. RESULTS: A total of 304 laboratory professionals participated in this study. More than half (52.6%) of the study participants were in the age group of 21 to 30 years and 264/304 (86.8%) were male. The majority (43.0%) of study participants had 6 to 10 years of experience and 212 (68.8%) did not receive clinical teaching skills training in the past two years. Regarding applying different hands-on teaching methods, the majority 38/304(12.5%) were not capable for role play and community based training, 49/304(16.1%) reported being Beginners, 85/304 (28%) said that they are advanced beginners in the competency. In this study, most study participants 98/304(32.2%) and 130/304(42.8%) perceived that they are competent and proficient in applying laboratory practice teaching methods respectively. CONCLUSION: The average cumulative level of competency from level 1 (not capable) to level 3 (advanced beginner), we found: learning in the practical teaching area 45.4%, clinical practicum teaching quality improvement and advocacy 42.9%, student assessment methods 42.7%, communication, collaboration and partnership 40.9%. Overall competence of preceptors (proportion of preceptors reported competent) was 57%. We recommend designing the performance interventions in the form of training by including communication skills for effective preceptor ship, students assessment and feedback, teaching and instruction strategies, planning for clinical practicum learning and principles of learning and teaching in practical areas.

Epidemiological Characterization of Dermatomycosis in Ethiopia.

BACKGROUND: Superficial mycosis is common worldwide and their epidemiological characteristics are different in different geographical areas and have shown variations in the last decades. The aim of this study was to analyze and characterize the epidemiology of dermatomycosis and their causative fungi species in Ethiopia between 2015 and 2019. METHODS: A laboratory-based cross-sectional study was conducted using the data of mycological examination and culture findings from all patients who visited the Dermatology Department of Arsho Advanced Medical Laboratory, Addis Ababa, Ethiopia. The direct wet mount microscopy and culture data of the isolates were collected from the database of the dermatology unit from 2015 to 2019 after permission was obtained from the laboratory head. The data were double-entered into Microsoft Excel, exported and analyzed using SPSS version 20. RESULTS: The total prevalence of fungi causing dermatomycosis was 67.7% (760/1122 cases) using direct wet mount microscopy and from these 489/1122 (43.5%) were culture positive. Dermatomycosis was found to be higher among females 694/1122 (61.9%) than male participants. Age group 25-44 years was the most affected 442/1122 (39.4%) followed by 1-14 years old 291/1122 (25.94%). Tinea unguium (50.8%) is the most common type of dermatomycosis followed by tinea capitis (24.1%) and tinea corporis (13.9%). Trichophyton spp. (32%) was the most highly distributed causative agent, followed by Epidermophyton spp. (20.2%) and Aspergillus fumigatus (8.3%). CONCLUSION: The retrospective analysis of epidemiological data collected at Arsho Advanced Medical Laboratory since 2015 showed a gradual increase in the frequency of tinea unguium and tinea pedis. However, during the past years, there was a gradual decline in the frequency of tinea corporis. In parallel with this variable pattern, the rate of isolation of non-dermatophytes especially Aspergillus fumigates and Candida species has shown a gradual increment during the past five years.

The Magnitude of Hematological Abnormalities Among COVID-19 Patients in Addis Ababa, Ethiopia.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a systemic infection with cardiovascular, pulmonary, gastrointestinal, neurological, and hematological manifestations. Abnormal hematological findings are thought to have a role in early risk stratification and prognostication of COVID-19 patients. However, the data on hematological abnormalities associated with the disease among Ethiopian COVID-19 patients are limited. OBJECTIVE: To determine the magnitude of hematological abnormalities among COVID-19 patients admitted at Millennium COVID-19 referral treatment center, Addis Ababa, Ethiopia. METHODS: A prospective cross-sectional study was conducted among COVID-19 patients admitted to Millennium COVID-19 referral treatment center from May to July, 2020. A total of 334 COVID-19 patients were included using convenience sampling. Socio-demographic data and disease severity status of admitted patients were recorded. Three milliliters of venous blood was collected and analyzed by Beckman Coulter DXH-600 automated analyzer to determine complete blood count (CBC). The data were entered and analyzed using SPSS version 23 software. Association of age, sex, and disease severity with hematological abnormalities was analyzed using binary logistic regression. An odds ratio and 95% confidence interval were used to measure the strength of association. P-value <0.05 was considered as statistically significant. RESULTS: Of 334 admitted COVID-19 patients, the majority were males (62.3%) and 69.8% had moderate disease conditions. The overall magnitude of any cytopenia and pancytopenia was 41% and 1.8%, respectively. The magnitude of anemia, thrombocytopenia, and leukopenia was 24.9%, 21.6%, and 5.4%, respectively. Lymphopenia (72.2%) was the most common hematological abnormality. COVID-19 patients with severe and critical disease were more likely to develop anemia, leukocytosis, neutrophilia, and combined neutrophilia-lymphopenia than those with moderate disease condition, with a significant association. CONCLUSION: Lymphopenia was the most common hematological abnormality observed among COVID-19 patients. Hematological abnormalities such as anemia, leukocytosis, neutrophilia, and combined neutrophilia-lymphopenia were significantly associated with disease severity. Monitoring and evaluation of hematological parameters could provide prognostic insight into the management and risk stratification of COVID-19 patients. However, further studies are required to fully understand the utility of hematological parameters for the prognosis of COVID-19 disease.

Rifampicin-Resistant Mycobacterium tuberculosis Among Patients with Presumptive Tuberculosis in Addis Ababa, Ethiopia.

BACKGROUND: Drug-resistant tuberculosis remains a major public health threat complicating tuberculosis control programs globally. Data on rifampicin resistance (RR), which is a surrogate marker for multidrug resistance, are limited among Ethiopian tuberculosis patients. This study aimed to determine the magnitude of rifampicin-resistant Mycobacterium tuberculosis (RR-MTB) among presumptive tuberculosis patients attending St. Peter Tuberculosis Specialized Hospital, Addis Ababa, Ethiopia. PATIENTS AND METHODS: A retrospective cross-sectional study was conducted at St. Peter Tuberculosis Specialized Hospital from January 2016 to December 2018. After checking completeness of the necessary information, data of tuberculosis-presumptive cases who underwent Gene Xpert® testing were collected from medical records using a data-extraction format prepared for this study purpose. Data were double entered and analyzed using SPSS version 20 statistical software. RESULTS: A total of 12,685 presumptive tuberculosis patients were included; of whom 54.5% were males and the mean age of the study participants was 40.3±18.7 years. Mycobacterium tuberculosis (MTB) was detected in 1714 participants (13.5%). Of these MTB cases, 169 cases (9.8%) were confirmed to have RR-MTB. Prevalence of MTB was relatively higher among males (15.1%, P=0.78); whereas RR-MTB was higher among females (10.3%, P=0.81). The incidence of MTB and RR-MTB was significantly associated with treatment history (P=0.042 and P=0.025), respectively. HIV infection has significantly associated with incidence of RR-MTB (P=0.032), but not with MTB (P˃0.05). Prevalence of MTB and RR-MTB had a declining trend through time, being 16.7% and 12.9%, 12.8% and 9.1%, and 12.2% and 7.9% in 2016, 2017 and 2018, respectively. CONCLUSION: This study showed a decreasing trend of both MTB and RR-MTB from 2016 to 2018 in an MTB, MDR-MTB, and TB/HIV co-infection high-burden setting, Addis Ababa, Ethiopia. Occurrence of MTB and RR-MTB was associated with treatment history. Therefore, improvement in treatment adherence of identified cases would be helpful to prevent emergence or re-emergence of MTB and RR-MTB cases.

Gonadal and Cortisol Hormone Profile among Male Chronic Khat, Marijuana, and Heroin Abuses.

BACKGROUND: Drugs of abuse could interfere with the hypothalamic-pituitary-gonadal axis, causing impaired functions of the gland and associated functions of target organs. Drugs of abuse tend to cause changes in the endocrine system, and these changes could be physiological, molecular, biochemical, genetic, and cellular. METHOD: A case-control study design was conducted from a total of 171 male consented study participants (148 drug abusers and 23 controls). The serum gonadal and cortisol hormone levels were assayed using the electrochemiluminescence immunoassay method. Socio-demographic variables were collected using a semi-structured questionnaire by the interview method. Nonparametric statistical tools (Mann-Whitney test and median) were used to compare the groups. In all cases, P < 0.05 was considered statistically significant. RESULT: The median age for drug abusers and control groups was 27, and the age difference between drug abusers and control group was not statistically important. The median estradiol levels among chronic khat chewers (39.4 pg/ml), marijuana (44 pg/mL), and users of heroin (40.2 pg/mL) were significantly higher than control groups (23 pg/mL), P < 0.003. However, the median luteinizing hormone levels among chronic khat chewers (5 IU/L), marijuana users (5 IU/L), and heroin users (5.6 IU/L) were significantly lower than those of control groups (6.2 IU/L), P < 0.02. The median testosterone levels among chronic khat chewers (6.1 ng/mL), marijuana users (6.3 ng/mL), and heroin users (6.6 ng/mL) were significantly lower than control groups (8.0 ng/mL), P < 0.003. However, cortisol and follicle stimulating hormone did not show statistically significant difference between users of khat, marijuana, and heroin compared with the control group. CONCLUSION: The drug abuser group had significantly lower testosterone and luteinizing hormone levels compared with control groups. Drug abuse has been shown to affect gonadal hormones in an unusual physiological phenomenon. These findings reveal the need for intervention programs to solve these problems.

Patient satisfaction with clinical laboratory services at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.

BACKGROUND: Monitoring patient satisfaction is an important and useful quality improvement tool for clinical laboratories in particular and health care organizations in general. Thus, this study aimed to assess patient satisfaction toward clinical laboratory services at Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. METHODS: A hospital-based cross-sectional study was conducted and a convenient sampling technique was applied to recruit study participants. A total of 210 patients who had received laboratory services were included. A self-administered predesigned, pretested, structured questionnaire was used, and data were collected through face-to-face interviews. A 5-point Likert scale with 1 and 5 indicating the lowest and highest levels of satisfaction, respectively, was used and their weighted average was used to categorize the satisfaction level of the patients. Chi square test was used (taking P≤0.05 as the statistically significant level) to find out if any association existed between the level of satisfaction and different attributes. Data were analyzed using SPSS version 20. RESULTS: The overall level of patient satisfaction toward clinical laboratory services in this study was 59.7% with a response rate of 210 (100%). The Likert scale results of patient satisfaction of the laboratory services revealed that the mean rating values ranged from 3.05 (±1.12) to 4.12 (±1.08) out of a possible 5. Among the different indicators, patients were highly satisfied with the cleanliness of facility (82%), maintenance of privacy and confidentiality (83.2%), and the cost of the laboratory service (86.5%), while they were dissatisfied with the location of the laboratory (56%), latrine accessibility and availability (58.4%), and latrine cleanness and comfort (63.8%). CONCLUSION: The whole availability of requested tests, availability of place in blood drawing room to put personal things, and waiting time for specimen collection were found to have a statistically significant association with the overall satisfaction of patients toward clinical laboratory services. Therefore, these could be the possible determinants among others that account for the dissatisfaction of patients with clinical laboratory services.
