Tuberculosis preventive treatment uptake among people living with HIV during COVID-19 period in Addis Ababa, Ethiopia: a retrospective data review.

BACKGROUND: Screening for tuberculosis (TB) and providing TB preventive treatment (TPT) along with antiretroviral therapy is key components of human immune deficiency virus (HIV) care. The uptake of TPT during the coronavirus disease 2019 (COVID-19) period has not been adequately assessed in Addis Ababa City Administration. This study aimed at assessing TPT uptake status among People living with HIV (PLHIV) newly initiated on antiretroviral therapy during the COVID-19 period at all public hospitals of Addis Ababa City Administration, Ethiopia. METHODS: A retrospective data review was conducted from April-July 2022. Routine District Health Information System 2 database was reviewed for the period from April 2020-March 2022. Proportion and mean with standard deviation were computed. Logistic regression analysis was conducted to assess factors associated with TPT completion. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 1,069 PLHIV, aged 18 years and above were newly initiated on antiretroviral therapy, and of these 1,059 (99.1%) underwent screening for TB symptoms. Nine hundred twelve (86.1%) were negative for TB symptoms. Overall, 78.8% (719) of cases who were negative for TB symptoms were initiated on TPT, and of these 70.5% and 22.8% were completed and discontinued TPT, respectively. Of 719 cases who were initiated on TPT, 334 (46.5%) and 385 (53.5%) were initiated on isoniazid plus rifapentine weekly for three months and Isoniazid preventive therapy daily for six months, respectively. PLHIV who were initiated on isoniazid plus rifapentine weekly for three months were more likely to complete TPT (adjusted odds ratio [AOR],1.68; 95% confidence interval [CI], 1.01, 2.79) compared to those who were initiated on Isoniazid preventive therapy daily for six months. CONCLUSION: While the proportion of PLHIV screened for TB was high, TPT uptake was low and far below the national target of achieving 90% TPT coverage. Overall a considerable proportion of cases discontinued TPT in this study. Further strengthening of the programmatic management of latent TB infection among PLHIV is needed. Therefore, efforts should be made by the Addis Ababa City Administration Health Bureau authorities and program managers to strengthen the initiation and completion of TPT among PLHIV in public hospitals.

Health related quality of life and its association with social support among people living with HIV/AIDS receiving antiretroviral therapy in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: People living with HIV/AIDS (PLWHA) are frequently confronted with severe social issues such as rejection, abandonment, criticism, and stigma. This would negatively affect their quality of life. Several studies have been conducted so far to assess factors affecting the health-related quality of life among people living with HIV/AIDS who are on antiretroviral therapy (ART) in Ethiopia. However, to our knowledge, there is no previous study that has summarized the results of the studies that investigated health-related quality of life (HRQOL) among PLWHA in Ethiopia. Therefore, the purpose of this review was to estimate the pooled prevalence of HRQOL and its association with social support among people living with HIV/AIDS (PLWHA) on ART in Ethiopia. METHODS: A systematic search was carried out using several electronic databases (PubMed, Science Direct, Web of Science, and Cochrane electronic), Google Scholar, Google, and a manual search of the literature on health-related quality of life among people living with HIV/AIDS who are on ART. A Microsoft Excel data extraction sheet was used to extract pertinent data from an individual study. To assess the heterogeneity of primary articles, the Cochrane Q test statistics and the I2 test were carried out, and a random effects meta-analysis was used to estimate the pooled prevalence of HRQOL. RESULT: Out of the 493 articles reviewed, ten with a total of 3257 study participants were eligible for meta-analysis. The pooled prevalence of HRQOL among people living with HIV/AIDS who are on antiretroviral therapy in Ethiopia was 45.27%. We found that strong perceived social support was significantly associated with higher levels of subjectively perceived HRQOL. PLWHA who were on ART and had good social support were four times more likely to report higher HRQOL when compared to their counterparts [AOR = 4.01, 95% CI 3.07-5.23]. CONCLUSION: A substantial number of PLWHA had poor HRQOL in Ethiopia. Social support was significantly associated with HRQOL among people living with HIV/AIDS. Hence, it's recommended to encourage suitable intervention at every follow-up visit, and psycho-social support is also warranted to improve the quality of life.

Assessment of maternal and child health care services performance in the context of COVID-19 pandemic in Addis Ababa, Ethiopia: evidence from routine service data.

BACKGROUND: In many settings, health care service provision has been modified to managing COVID-19 cases, and this has been affecting the provision of maternal and child health services. The aim of this study was to assess trends in selected maternal and child health services performance in the context of COVID-19 pandemic. METHODS: A cross-sectional data review was conducted in Addis Ababa, Ethiopia from April to May 2021. Routine health management information system database was reviewed from Addis Ababa Health Bureau for the period from July 2019 to March 2021 across all quarters. Proportion and mean with standard deviation were computed. T-test was used to assess statistically significant differences in services mean performance. RESULTS: Postnatal care  visit, new contraceptives accepters, safe abortion care and number of under-5 years old children treated for pneumonia significantly decreased by 9.3% (p-value 0.04), 20.3% (p-value 0.004), 23.7% (p-value 0.01) and 77.2% (p-value < 0.001), respectively during the first 8 months of the COVID-19 pandemic compared to the previous 8 months' average performance. The trends in Antenatal care first visit, new contraceptive accepters, pentavalent-3 vaccination and under-five children treated for pneumonia began to decline in January to  March 2020, a quarter when the COVID-19 pandemic began; with accelerated declines in April to June 2020 following national lockdown. The trends for the stated services began to increase during July-September 2020, the last quarter of national lockdown. Contraceptive accepters and pentavalent-1 vaccination continued to decline and showed no recovery until January-March 2021 when this study was completed. CONCLUSIONS: Most of the maternal and child health services performance declined following the onset of COVID-19 pandemic and national lockdown, and most of the services began recovering during July-September 2020, the last quarter of national lockdown. However, new and repeat contraceptive accepters and pentavalent-1 recipients continue to decline and show no recovery during end of the study period. Implementing COVID-19 prevention measures and assuring the community about the safety of service delivery is imperative to ensure continuity of the maternal and child health services. Regular monitoring and evaluation of services performance is required to identify slowly recovering services and respond to potentially volatile changes during the COVID-19 pandemic.

Seroepidemiology of respiratory syncytial virus infection in rural and semi-rural areas of the Littoral region of Cameroon.

BACKGROUND: The respiratory syncytial virus (RSV) has been established as a leading cause of acute lower respiratory illness (ALRI) in infants and children. In 2015, the global disease burden (GBD) study estimated that the overall RSV-ALRI mortality could be as high as 118,200, with most death occurring in low- and middle-incomes countries (LMIC). This study aimed to assess the burden of RSV infection among children less than 2 years with acute respiratory infections (ARI) in the Littoral region of Cameroon. METHODS: We carried out a cross-sectional study in seven health centres in the Littoral region of Cameroon. Venous blood was collected using serum separation tubes from eligible children who visited these health centres with acute respiratory infections. ELISA (Enzyme-linked immunosorbent assay) testing was used to assess the seroprevalence of anti-IgM RSV for the total population and by selected demographic and health parameters and potential risk factors. RESULTS: The overall RSV-associated ARI seroprevalence was 33% (95%CI:23.6-42.3; 33/100 children). The only demographic factor significantly associated with RSV acquisition was age of 6 months and below (odds ratio: 7.54 (2.62, 23.36); p = 0.000). Children who were clinically diagnosed to be concomitantly infected with malaria had a lower risk of RSV infection (odds ratio: 0.38 (0.14, 0.95; P = 0.03). CONCLUSIONS: The RSV burden is high among children less than 2 years with ARI in the Littoral region of Cameroon. There is a need for an effective public health RSV surveillance system with standard laboratory techniques and equipment to better understand the RSV disease age-specific incidence, seasonality, risk factors and RSV burden among patients in communities in Cameroon.

Mapping time use in clinical trials for vaccines against emerging infectious diseases.

BACKGROUND: Vaccines are potent tools to prevent outbreaks of emerging infectious diseases from becoming epidemics and need to be developed at an accelerated pace to have any impact on the course of an ongoing epidemic. The aim of this study was to describe time use in the execution of vaccine trials, to identify steps that could be accelerated to improve preparedness and planning for future emerging infectious diseases vaccine trials. METHODS: We used a mixed-methods approach to map time use and process steps that could be accelerated during vaccine trials. Trials for vaccines against infectious diseases registered in three global trial databases reported in the period 2011-2017 were eligible to join the survey. We invited sponsors to contribute data through a predefined structured questionnaire for clinical trial process metrics. Data were stratified by trial phase, disease type (i.e. emerging infectious diseases or not emerging infectious diseases), sponsor type, and continent. Qualitative interviews were conducted with purposively selected sponsors, and thematic analysis of the interview transcripts was performed. RESULTS: Based on data from 155 vaccine trials including 29,071 subjects, 52% were phase I, 23% phase II, and 25% phase III. We found that the regulatory approval, subject enrollment, study execution, and study close-out accounted for most of the cycle time of the vaccine trial process. Cycle times for the regulatory and ethical approvals, contract agreement, site initiation, and study execution were shorter in trials conducted during outbreaks. Qualitative interviews indicated that early engagement of the regulatory and independent ethical committee authorities in planning the vaccine trials was critical for saving time in trial approval. Furthermore, adapting the trial implementation to the reality of the study sites and active involvement of the local investigators during the planning of the trial and protocol writing were stated to be of paramount importance to successful completion of trials at an accelerated pace. CONCLUSION: The regulatory approval, subject recruitment, study execution, and close-out cycle times accounted for most of the vaccine trial time use and are activities that could be accelerated during a vaccine trial planning and implementation. We encourage tracking of key cycle time metrics and facilitating sharing of knowledge across industry and academia, as this may serve to reduce the time from index case detection to access of a vaccine during emerging infectious diseases epidemics.

Lipid droplets and the transcriptome of Mycobacterium tuberculosis from direct sputa: a literature review.

Mycobacterium tuberculosis (Mtb), the main etiology of tuberculosis (TB), is predominantly an intracellular pathogen that has caused infection, disease and death in humans for centuries. Lipid droplets (LDs) are dynamic intracellular organelles that are found across the evolutionary tree of life. This review is an evaluation of the current state of knowledge regarding Mtb-LD formation and associated Mtb transcriptome directly from sputa.Based on the LD content, Mtb in sputum may be classified into three groups: LD positive, LD negative and LD borderline. However, the clinical and evolutionary importance of each state is not well elaborated. Mounting evidence supports the view that the presence of LD positive Mtb bacilli in sputum is a biomarker of slow growth, low energy state, towards lipid degradation, and drug tolerance. In Mtb, LD may serve as a source of chemical energy, scavenger of toxic compounds, prevent destruction of Mtb through autophagy, delay trafficking of lysosomes towards the phagosome, and contribute to Mtb persistence. It is suggest that LD is a key player in the induction of a spectrum of phenotypic and metabolic states of Mtb in the macrophage, granuloma and extracellular sputum microenvironment. Tuberculosis patients with high proportion of LD positive Mtb in pretreatment sputum was associated with higher rate of poor treatment outcome, indicating that LD may have a clinical application in predicting treatment outcome.The propensity for LD formation among Mtb lineages is largely unknown. The role of LD on Mtb transmission and disease phenotype (pulmonary TB vs extra-pulmonary TB) is not well understood. Thus, further studies are needed to understand the relationships between LD positivity and Mtb lineage, Mtb transmission and clinical types.

Developing vaccines against epidemic-prone emerging infectious diseases.

Today's world is characterized by increasing population density, human mobility, urbanization, and climate and ecological change. This global dynamic has various effects, including the increased appearance of emerging infectious diseases (EIDs), which pose a growing threat to global health security.Outbreaks of EIDs, like the 2013-2016 Ebola outbreak in West Africa or the current Ebola outbreak in Democratic Republic of the Congo (DRC), have not only put populations in low- and middle-income countries (LMIC) at risk in terms of morbidity and mortality, but they also have had a significant impact on economic growth in affected regions and beyond.The Coalition for Epidemic Preparedness Innovation (CEPI) is an innovative global partnership between public, private, philanthropic, and civil society organizations that was launched as the result of a consensus that a coordinated, international, and intergovernmental plan was needed to develop and deploy new vaccines to prevent future epidemics.CEPI is focusing on supporting candidate vaccines against the World Health Organization (WHO) Blueprint priority pathogens MERS-CoV, Nipah virus, Lassa fever virus, and Rift Valley fever virus, as well as Chikungunya virus, which is on the WHO watch list. The current vaccine portfolio contains a wide variety of technologies, ranging across recombinant viral vectors, nucleic acids, and recombinant proteins. To support and accelerate vaccine development, CEPI will also support science projects related to the development of biological standards and assays, animal models, epidemiological studies, and diagnostics, as well as build capacities for future clinical trials in risk-prone contexts.

Tuberculosis infectious pool and associated factors in East Gojjam Zone, Northwest Ethiopia.

BACKGROUND: Globally, tuberculosis (TB) lasts a major public health concern. Using feasible strategies to estimate TB infectious periods is crucial. The aim of this study was to determine the magnitude of TB infectious period and associated factors in East Gojjam zone. METHODS: An institution-based prospective study was conducted among 348 pulmonary TB (PTB) cases between December 2017 and December 2018. TB cases were recruited from all health facilities located in Hulet Eju Enesie, Enebse Sarmider, Debay Tilatgen, Dejen, Debre-Markos town administration, and Machakel districts. Data were collected through an exit interview using a structured questionnaire and analyzed by IBM SPSS version25. The TB infectious period of each patient category was determined using the TB management time and sputum smear conversion time. The sum of the infectious period of each patient category gave the infectious pool of the study area. A multivariable logistic regression analysis was used to identify factors associated with the magnitude of TB infectious period. RESULTS: Of the total participated PTB cases, 209(60%) were male, 226(65%) aged < 30 years, 205(59%) were from the rural settings, and 77 (22%) had comorbidities. The magnitude of the TB infectious pool in the study area was 78,031 infectious person-days. The undiagnosed TB cases (44,895 days), smear-positive (14,625 days) and smear-negative (12,995 days) were major contributors to the infectious pool. The overall average median TB management time was 142.4 days (IQR, 98-238 days). Similarly, the average sputum smear conversion time of PTB cases (new and repeat) was 46 days. Residence, knowledge, form of TB, smoking, alcohol history, distance from the facility, comorbidity history and stigma were statistically significant factors TB infectious period (p-value< 0.05). CONCLUSIONS: The magnitude of the TB infectious pool is high even if it is lower than the findings of previous studies. This might be an indicator of poor access to TB services, service delays, low community awareness, impaired facility readiness, and poor transportation. Improving personal awareness and behavior, timely management of commodities, and using the TB management time in TB control are crucial to improving TB control activities.

The prevalence and predictors of domestic violence among pregnant women in Southeast Oromia, Ethiopia.

INTRODUCTION: Domestic violence is a common global health problem and relatively hidden and ignored form of violence against pregnant women. The magnitude of domestic violence among pregnant women is higher in low and middle-income countries including Ethiopia as compared with developed countries. Domestic violence is a violation of human right and associated with numerous adverse outcomes for mothers and the offspring. However, research on domestic violence and predictors against pregnant women is limited in Ethiopia. Therefore, the aim of this study was to assess the magnitude and predictors of domestic violence among pregnant women in southeast Oromia, Ethiopia. METHODS: Cross-sectional study design was utilized among 299 pregnant women selected by systematic sampling technique. A structured World Health Organization (WHO) multi-country study questionnaire on women health and domestic violence was used to measure domestic violence. Binary and multivariable logistic regression models were fitted. Odds ratios (OR) with the corresponding 95% confidence interval (95%CI)) was computed to assess the strength of association. RESULT: The prevalence of domestic violence was 64.6% (CI: 58.5, 69.9%). Physical violence was reported as the commonest type of violence (44.1%) followed by psychological (39.1%) and sexual (23.7%) violence. In the multivariable analysis, being illiterate (OR = 6.3; 95%CI: 2.23, 11.65), Husband's alcohol consumption (OR = 5.726; 95% CI 1.873, 11.51), husband history of arrest (OR = 2.59; 95% CI: 1.15, 5.88) and occupation of husband (farmer) (OR = 3.26; 95% CI: 1.29, 8.25) were significantly associated with domestic violence against pregnant women. CONCLUSION: This study revealed that a remarkable proportion of pregnant women had experienced domestic violence in their lifetime (64.6%). Being illiterate, husband's alcohol consumption, occupation (farmer and self-employed), and history of arrest were significantly associated with domestic violence among pregnant women. The findings suggest screening for domestic violence among pregnant women visiting antenatal care clinic and early intervention based on the findings. Integrating health education program on domestic violence with the existing maternal health program is warranted.

Health care seeking behavior for depression in Northeast Ethiopia: depression is not considered as illness by more than half of the participants.

BACKGROUND: Depression is one of the most disabling and chronic mental illnesses. Despite its high burden, many people suffering from depression did not perceive that they had a treatable illness and consequently most of them did not seek professional help. The aim of this study was to assess the level of professional help-seeking behavior and associated factors among individuals with depression. METHODS AND MATERIALS: The community-based cross-sectional study was conducted among residents of Dessie, Northeast Ethiopia. First, 1165 residents were screened for depression using patient health questionnaire and then 226 individuals who were screened positive for probable depression were interviewed with General Help-Seeking Questionnaire to assess the professional help-seeking behavior of participants with depression. Major associated variables were identified using logistic regression with 95% confidence interval (CI), and variables with a p value less than 0.05 were considered statistically significant. RESULTS: Among the total participants with depressive symptoms, only 25.66% of them did seek professional help. Being female [adjusted odds ratio (AOR) = 2.769, 95% CI (1.280, 5.99)], current alcohol drinking [AOR = 2.74, 95% CI (1.265, 5.940)], co-morbid medical-surgical illness [AOR = 4.49, 95% CI (1.823, 11.071)], perceiving depression as illness [AOR = 2.44, 95% CI (1.264, 4.928)], having moderate depressive symptoms [AOR = 2.54, 95% CI (1.086, 5.928)] and moderately severe depressive symptoms [AOR = 7.67, 95% CI (2.699, 21.814)] were significantly associated with help seeking behavior of participants. CONCLUSIONS: Level of professional help-seeking behavior is as low as previous studies in different countries. The severity of depressive symptoms, co-morbidity of medical-surgical illness, current drinking of alcohol, being female, and perceiving depression as illness were significantly associated with professional help-seeking behavior for depressive symptoms. Working on mental health literacy in the community is important to increase help-seeking behavior.

Nε- and O-Acetylation in Mycobacterium tuberculosis Lineage 7 and Lineage 4 Strains: Proteins Involved in Bioenergetics, Virulence, and Antimicrobial Resistance Are Acetylated.

Increasing evidence demonstrates that lysine acetylation is involved in Mycobacterium tuberculosis (Mtb) virulence and pathogenesis. However, previous investigations in Mtb have only monitored acetylation at lysine residues using selected reference strains. We analyzed the global Nε- and O-acetylation of three Mtb isolates: two lineage 7 clinical isolates and the lineage 4 H37Rv reference strain. Quantitative acetylome analysis resulted in identification of 2490 class-I acetylation sites, 2349 O-acetylation and 141 Nε-acetylation sites, derived from 953 unique proteins. Mtb O-acetylation was thereby significantly more abundant than Nε-acetylation. The acetylated proteins were found to be involved in central metabolism, translation, stress responses, and antimicrobial drug resistance. Notably, 261 acetylation sites on 165 proteins were differentially regulated between lineage 7 and lineage 4 strains. A total of 257 acetylation sites on 161 proteins were hypoacetylated in lineage 7 strains. These proteins are involved in Mtb growth, virulence, bioenergetics, host-pathogen interactions, and stress responses. This study provides the first global analysis of O-acetylated proteins in Mtb. This quantitative acetylome data expand the current understanding regarding the nature and diversity of acetylated proteins in Mtb and open a new avenue of research for exploring the role of protein acetylation in Mtb physiology.

Deciphering the recent phylogenetic expansion of the originally deeply rooted Mycobacterium tuberculosis lineage 7.

BACKGROUND: A deeply rooted phylogenetic lineage of Mycobacterium tuberculosis (M. tuberculosis) termed lineage 7 was discovered in Ethiopia. Whole genome sequencing of 30 lineage 7 strains from patients in Ethiopia was performed. Intra-lineage genome variation was defined and unique characteristics identified with a focus on genes involved in DNA repair, recombination and replication (3R genes). RESULTS: More than 800 mutations specific to M. tuberculosis lineage 7 strains were identified. The proportion of non-synonymous single nucleotide polymorphisms (nsSNPs) in 3R genes was higher after the recent expansion of M. tuberculosis lineage 7 strain started. The proportion of nsSNPs in genes involved in inorganic ion transport and metabolism was significantly higher before the expansion began. A total of 22346 bp deletions were observed. Lineage 7 strains also exhibited a high number of mutations in genes involved in carbohydrate transport and metabolism, transcription, energy production and conversion. CONCLUSIONS: We have identified unique genomic signatures of the lineage 7 strains. The high frequency of nsSNP in 3R genes after the phylogenetic expansion may have contributed to recent variability and adaptation. The abundance of mutations in genes involved in inorganic ion transport and metabolism before the expansion period may indicate an adaptive response of lineage 7 strains to enable survival, potentially under environmental stress exposure. As lineage 7 strains originally were phylogenetically deeply rooted, this may indicate fundamental adaptive genomic pathways affecting the fitness of M. tuberculosis as a species.

Patients' and health system's delays in the diagnosis and treatment of new pulmonary tuberculosis patients in West Gojjam Zone, Northwest Ethiopia: a cross-sectional study.

BACKGROUND: Tuberculosis (TB) is a major public health concern in the developing world. Early diagnosis and prompt initiation of treatment is essential for effective TB control. The aim of this study was to determine the length and analyze associated factors of patients' and health system's delays in the diagnosis and treatment of new pulmonary TB (PTB) patients. METHODS: A cross-sectional study was conducted in 30 randomly selected public health facilities in West Gojjam Zone, Amhara Region, Ethiopia. Newly diagnosed PTB patients who were ≥15 years of age were consecutively enrolled in the study. Patients' delay (the time period from onset of TB symptoms to first presentation to a formal health provider) and health system's delay (the time period from first presentation to a formal health provider to first start of TB treatment) were measured. Median patients' and health system's delays were calculated. Mixed effect logistic regression was used to analyze predictors of patients' and health system's delays. RESULTS: Seven hundred six patients were enrolled in the study. The median patients' delay was 18 days (interquartile range [IQR]: 8-34 days) and the median health system's delay was 22 days (IQR: 4-88 days). Poor knowledge of TB (adjusted odds ratio [AOR], 2.33; 95 % confidence interval [CI], 1.34-4.05), first visit to non-formal health provider (AOR, 47.56; 95 % CI, 26.31-85.99), self-treatment (AOR, 10.11; 95 % CI, 4.53-22.56) and patients' age (≥45 years) (AOR, 2.99; 95 % CI, 1.14-7.81) were independent predictors of patients' delay. Smear-negative TB (AOR, 1.88; 95 % CI, 1.32-2.68) and first visit to public health centers (AOR, 2.22; 95 % CI, 1.52-3.25) and health posts (AOR, 5.86; 95 % CI, 1.40-24.39) were found to be independent predictors of health system's delay. CONCLUSIONS: The health system's delay in this study was long and contributed more than 50 % of the total delay. Better TB diagnostic tools to complement sputum smear microscopy are needed to early diagnose PTB cases at peripheral health facilities. In addition, due emphasis should be given to increase public awareness about symptoms and consequences of TB disease.

Magnitude and associated factors of aggressive behaviour among patients with bipolar disorder at Amanual Mental Specialized Hospital, outpatient department, Addis Ababa, Ethiopia: cross-sectional study.

BACKGROUND: Aggressive behavior is a challenging behavior among bipolar patients that causes poor social interaction and hospitalization. But, there is no information regards of the magnitude and contributing factors for aggressive behaviour among bipolar patients in Ethiopia. Therefore, this study was designed to assess the prevalence and associated factors of aggressive behaviour among patients with bipolar disorder. METHOD: An institutional based cross sectional study was conducted at Amanual Mental Specialized Hospital from May 1 to June 1, 2015 among 411 participants who were selected by systematic random sampling technique. Data was collected by interview technique by using Modified Overt Aggression Scale, entered and analyzed by using Epi Data 3.1 and Statistical Package for Social Science version 20, respectively. Adjusted Odd Ratio (AOR) with 95% Confidence Interval (CI) were used to show the odd and P-value <0.05 was considered as statistically significant. RESULTS: A total of 411 bipolar patients were included in the study and the prevalence of aggressive behaviour was 29.4%. Significant associated factors for aggression were, having two or more episode [AOR = 2.35 95% CI (1.18, 4.69)], previous history of aggression, [AOR = 3.72, 95% CI (1.54, 8.98)], depressive symptoms [AOR = 3.63, 95% CI (1.89, 6.96)], psychotic symptoms [AOR = 5.41,95% CI (2.88, 10.1)], manic symptoms [AOR = 3.85,95% CI (2.06, 7.19)], poor medication adherence [AOR = 3.73 95% CI (1.71, 8.13)], poor social support [AOR = 2.99 95% CI (1.30, 6.91)] and current use of substance[AOR = 2.17 95% CI (1.16, 4.06)]. CONCLUSION: Prevalence of aggression is high among bipolar patients and associated with many factors. So it needs public health attention to decrease aggression among bipolar patients.

Assessment of health system challenges and opportunities for possible integration of diabetes mellitus and tuberculosis services in South-Eastern Amhara Region, Ethiopia: a qualitative study.

BACKGROUND: The double burden of tuberculosis (TB) and diabetes mellitus (DM) is a significant public health problem in low and middle income countries. However, despite the known synergy between the two disease conditions, services for TB and DM have separately been provided. The objective of this study was to explore health system challenges and opportunities for possible integration of DM and TB services. METHODS: This was a descriptive qualitative study which was conducted in South-Eastern Amhara Region, Ethiopia. Study participants included health workers (HWs), program managers and other stakeholders involved in TB and DM prevention and control activities. Purposive sampling was applied to select respondents. In order to capture diversity of opinions among participants, maximum variation sampling strategy was applied in the recruitment of study subjects. Data were collected by conducting four focus group discussions and 12 in-depth interviews. Collected data were transcribed verbatim and were thematically analyzed using NVivo 10 software program. RESULT: A total of 44 (12 in-depth interviews and 32 focus group discussion) participants were included in the study. The study participants identified a number of health system challenges and opportunities affecting the integration of TB-DM services. The main themes identified were: 1. Unavailability of system for continuity of DM care. 2. Inadequate knowledge and skills of health workers. 3. Frequent stockouts of DM supplies. 4. Patient's inability to pay for DM services. 5. Poor DM data management. 6. Less attention given to DM care. 7. Presence of a well-established TB control program up to the community level. 8. High level of interest and readiness among HWs, program managers and leaders at different levels of the health care delivery system. CONCLUSION: The study provided insights into potential health systems challenges and opportunities that need to be considered in the integration of TB-DM services. Piloting TB and DM integrated services in selected HFs of the study area is needed to assess feasibility for possible full scale integration of services for the two comorbid conditions.

Mycobacterium tuberculosis lineage 7 strains are associated with prolonged patient delay in seeking treatment for pulmonary tuberculosis in Amhara Region, Ethiopia.

Recent genotyping studies of Mycobacterium tuberculosis in Ethiopia have reported the identification of a new phylogenetically distinct M. tuberculosis lineage, lineage 7. We therefore investigated the genetic diversity and association of specific M. tuberculosis lineages with sociodemographic and clinical parameters among pulmonary TB patients in the Amhara Region, Ethiopia. DNA was isolated from M. tuberculosis-positive sputum specimens (n=240) and analyzed by PCR and 24-locus mycobacterial interspersed repetitive unit-variable-number tandem-repeat (MIRU-VNTR) analysis and spoligotyping. Bioinformatic analysis assigned the M. tuberculosis genotypes to global lineages, and associations between patient characteristics and genotype were evaluated using logistic regression analysis. The study revealed a high diversity of modern and premodern M. tuberculosis lineages, among which approximately 25% were not previously reported. Among the M. tuberculosis strains (n=138) assigned to seven subgroups, the largest cluster belonged to the lineage Central Asian (CAS) (n=60; 26.0%), the second largest to lineage 7 (n=36; 15.6%), and the third largest to the lineage Haarlem (n=35; 15.2%). Four sublineages were new in the MIRU-VNTRplus database, designated NW-ETH3, NW-ETH1, NW-ETH2, and NW-ETH4, which included 24 (10.4%), 18 (7.8%), 8 (3.5%), and 5 (2.2%) isolates, respectively. Notably, patient delay in seeking treatment was significantly longer among patients infected with lineage 7 strains (Mann-Whitney test, P<0.008) than in patients infected with CAS strains (adjusted odds ratio [AOR], 4.7; 95% confidence interval [CI], 1.6 to 13.5). Lineage 7 strains also grew more slowly than other M. tuberculosis strains. Cases of Haarlem (OR, 2.8; 95% CI, 1.2 to 6.6) and NW-ETH3 (OR, 2.8; 95% CI, 1.0 to 7.3) infection appeared in defined clusters. Intensified active case finding and contact tracing activities in the study region are needed to expedite diagnosis and treatment of TB.

Tuberculosis management time: an alternative parameter for measuring the tuberculosis infectious pool.

OBJECTIVE: To demonstrate the application of TB management time as an alternative parameter to estimate the size of the tuberculosis infectious pool in West Gojjam Zone of Amhara Region, Ethiopia. METHODS: In this study, we used the TB management time, i.e. the number of days from start of cough until start of treatment, to determine the infectious period. Patients with sputum smear-positive and smear-negative pulmonary TB, retreatment and an estimated number of undetected cases were included. The infectious pool was then estimated as the annual number of infectious person days in a defined population. RESULTS: The TB management time of presently undiagnosed TB cases and sputum smear-positive patients contributed significantly to the infectious pool with 151,840 and 128,750 infectious person days per year, respectively. The total infectious pool including sputum smear-negative TB cases and retreatment patients in the study area was estimated at 325,410 person days or 15,447 person days per 100,000 population during the study year. CONCLUSION: Recording TB management time may be used to estimate the infectious pool of TB and to monitor programme performance in the community.

Time to first consultation, diagnosis and treatment of TB among patients attending a referral hospital in Northwest, Ethiopia.

BACKGROUND: Early detection and treatment of TB is essential for the success of TB control program performance. The aim of this study was to determine the length and analyze predictors of patients', health systems' and total delays among patients attending a referral hospital in Bahir Dar, Ethiopia. METHODS: A cross-sectional study was conducted among newly diagnosed TB cases ≥ 15 years of age. Delay was analyzed at three levels: the periods between 1) onset of TB symptoms and first visit to medical provider, i.e. patients' delay, 2) the first visit to a medical provider and the initiation of treatment i.e. health systems' delay and 3) onset of TB symptoms and initiation of treatment i.e. total delay. Uni- and multi-variate logistic regression analyses were performed to investigate predictors of patients', health systems' and total delays. RESULTS: The median time of patients' delay was 21 days [(interquartile range (IQR) (7 days, 60 days)]. The median health systems' delay was 27 days (IQR 8 days, 60 days) and the median total delay was 60 days (IQR 30 days, 121 days). Patients residing in rural areas had a three-fold increase in patients' delay compared to those from urban areas [Adjusted Odds Ratio (AOR) 3.4; 95% (CI 1.3, 8.9)]. Extra-pulmonary TB (EPTB) cases were more likely to experience delay in seeking treatment compared to pulmonary (PTB) cases [(AOR 2.6; 95% (CI 1.3, 5.4)]. Study subjects who first visited health centres [(AOR) 5.1; 95% (CI 2.1, 12.5)], private facilities [(AOR) 3.5; 95% (CI 1.3, 9.7] and health posts [(AOR) 109; 95% (CI 12, 958], were more likely to experience an increase in health systems' delay compared to those who visited hospitals. CONCLUSIONS: The majority of TB patients reported to medical providers within an acceptable time after the onset of symptoms. Rural residence was associated with patients' and total delays. Providing the population with information about TB symptoms and the importance of early health seeking may be an efficient way to decrease TB transmission, morbidity and mortality. Establishing efficient TB diagnostic and treatment facilities at the periphery level is imperative to reduce diagnostic delay and expedite TB treatment.

Problematic coffee use and associated factors among medical and health science students in Dilla University, Ethiopia.

Objective: Coffee holds a cherished place in Ethiopian culture, its consumption among students raises concerns despite its perceived benefits for alertness and productivity. Moderate caffeine intake remains unproblematic, but exceeding 400 mg daily can trigger detrimental health effects such as fatigue, memory impairment, and even attention-deficit disorder. Research on problematic coffee use among young adults, specifically Ethiopian students, remains limited, hindering our understanding of its potential scope and impact. To address this knowledge gap, researchers at Dilla University, Ethiopia, undertook a comprehensive study in 2022, focusing on the university's student population. This investigation holds significant potential to unveil the previously obscured landscape of excessive coffee consumption in this demographic and inform future research and potential interventions. Methodology: An institutional-based cross-sectional study design was conducted in August-July, 2022. To measure problematic coffee use, this study used the Diagnostic Statistical Manual five criteria for substance use disorder. Those who scored >2 out of 11 criteria were considered to have problematic coffee use. To measure a significant association between the outcome and independent variable, a multivariable logistic regression analysis at p < 0.05 and 95% confidence interval was employed. Result: This study included 414 respondents. More than half of the respondents, 347 (59.7%) were male. Out of all respondents, 182 (44.0%) had a boy/girlfriend. Nearly half of the respondents, 218 (52.7%) were orthodox, Christian religion followers. According to this study's findings, 137 (33.1%) respondents were considered to have problematic coffee use. Multivariable logistic regression analysis showed that 5-10 years duration of coffee use (AOR = 4.62, 95% CI: 2.96-7.85; p = 0.001), start to use coffee before joining university (AOR = 2.977, 95% CI: 1.332-6.653; p = 0.008) and 6-9 cups of daily coffee use (AOR = 3.26, 95% CI: 2.14-5.89; p = 0.00) were associated with problematic coffee use. Conclusion: This study showed that one-third of the respondents had problematic coffee use. The starting point, duration, and amount of use had a strong association with problematic coffee use. Hence, focusing on addressing the mental health challenges associated with problematic/excessive coffee consumption among higher education students is advisable. Additionally, promoting awareness of problematic/excessive coffee use and its potential remedies is recommended.
