RESUMEN

Inorganic polyphosphate (polyP) is primarily synthesized by Polyphosphate Kinase-1 (PPK-1) and regulates numerous cellular processes, including energy metabolism, stress adaptation, drug tolerance, and microbial pathogenesis. Here, we report that polyP interacts with acyl CoA carboxylases, enzymes involved in lipid biosynthesis in Mycobacterium tuberculosis. We show that deletion of ppk-1 in M. tuberculosis results in transcriptional and metabolic reprogramming. In comparison to the parental strain, the Δppk-1 mutant strain had reduced levels of virulence-associated lipids such as PDIMs and TDM. We also observed that polyP deficiency in M. tuberculosis is associated with enhanced phagosome-lysosome fusion in infected macrophages and attenuated growth in mice. Host RNA-seq analysis revealed decreased levels of transcripts encoding for proteins involved in either type I interferon signaling or formation of foamy macrophages in the lungs of Δppk-1 mutant-infected mice relative to parental strain-infected animals. Using target-based screening and molecular docking, we have identified raloxifene hydrochloride as a broad-spectrum PPK-1 inhibitor. We show that raloxifene hydrochloride significantly enhanced the activity of isoniazid, bedaquiline, and pretomanid against M. tuberculosis in macrophages. Additionally, raloxifene inhibited the growth of M. tuberculosis in mice. This is an in-depth study that provides mechanistic insights into the regulation of mycobacterial pathogenesis by polyP deficiency.

RESUMEN

The human immunodeficiency virus type 1 (HIV-1) reservoir consists of latently infected cells which present a major obstacle to achieving a functional cure for HIV-1. The formation and maintenance of HIV-1 latency have been extensively studied, and latency-reversing agents (LRAs) that can reactivate latent HIV-1 by targeting the involved host factors are developed; however, their clinical efficacies remain unsatisfactory. Therefore, it is imperative to identify novel targets for more potential candidates or better combinations for LRAs. In this study, we utilized CRISPR affinity purification in situ of regulatory elements system to screen for host factors associated with the HIV-1 long terminal repeat region that could potentially be involved in HIV-1 latency. We successfully identified that origin recognition complex 1 (ORC1), the largest subunit of the origin recognition complex, contributes to HIV-1 latency in addition to its function in DNA replication initiation. Notably, ORC1 is enriched on the HIV-1 promoter and recruits a series of repressive epigenetic elements, including DNMT1 and HDAC1/2, and histone modifiers, such as H3K9me3 and H3K27me3, thereby facilitating the establishment and maintenance of HIV-1 latency. Moreover, the reactivation of latent HIV-1 through ORC1 depletion has been confirmed across various latency cell models and primary CD4+ T cells from people living with HIV-1. Additionally, we comprehensively validated the properties of liquid-liquid phase separation (LLPS) of ORC1 from multiple perspectives and identified the key regions that promote the formation of LLPS. This property is important for the recruitment of ORC1 to the HIV-1 promoter. Collectively, these findings highlight ORC1 as a potential novel target implicated in HIV-1 latency and position it as a promising candidate for the development of novel LRAs. IMPORTANCE: Identifying host factors involved in maintaining human immunodeficiency virus type 1 (HIV-1) latency and understanding their mechanisms prepares the groundwork to discover novel targets for HIV-1 latent infection and provides further options for the selection of latency-reversing agents in the "shock" strategy. In this study, we identified a novel role of the DNA replication factor origin recognition complex 1 (ORC1) in maintaining repressive chromatin structures surrounding the HIV-1 promoter region, thereby contributing to HIV-1 latency. This discovery expands our understanding of the non-replicative functions of the ORC complex and provides a potential therapeutic strategy for HIV-1 cure.

RESUMEN

TFIID binds promoter DNA to recruit RNA polymerase II and other basal factors for transcription. Although the TATA-binding protein (TBP) subunit of TFIID is necessary and sufficient for in vitro transcription, the TBP-associated factor (TAF) subunits recognize downstream promoter elements, act as coactivators, and interact with nucleosomes. In yeast nuclear extracts, transcription induces stable TAF binding to downstream promoter DNA, promoting subsequent activator-independent transcription reinitiation. In vivo, promoter responses to TAF mutations correlate with the level of downstream, rather than overall, Taf1 cross-linking. We propose a new model in which TAFs function as reinitiation factors, accounting for the differential responses of promoters to various transcription factor mutations.

RESUMEN

BACKGROUND: Prevalence of smoking is high among patients receiving care in safety-net settings, and there is a need to better understand patient factors associated with smoking cessation and receipt of cessation services. OBJECTIVE: To identify patient factors associated with smoking cessation attempts and receipt of cessation counseling and pharmacotherapy in a large safety-net health system. DESIGN: We conducted a retrospective cohort analysis using EHR data in a safety-net system in San Francisco, CA. PARTICIPANTS: We included 7384 adult current smokers who had at least three unique primary care encounters with documented smoking status between August 2019 and April 2022. MAIN MEASURES: We assessed four outcomes using multivariate generalized estimating equation models: (1) any cessation attempt, indicating a transition in smoking status from "current smoker" to "former smoker"; (2) sustained cessation, defined as transition in smoking status from current smoker to former smokers for two or more consecutive visits; (3) receipt of smoking cessation counseling from healthcare providers; and (4) receipt of pharmacotherapy. KEY RESULTS: Of 7384 current adult smokers, 17.6% had made any cessation attempt, and of those 66.5% had sustained cessation. Most patients (81.1%) received counseling and 41.8% received pharmacotherapy. Factors associated with lower odds of any cessation attempt included being aged 45-64, non-Hispanic black, and experiencing homelessness. The factor associated with lower odds of sustained cessation was being male. Factors associated with lower odds of receiving counseling were being insured by Medicaid or being uninsured. Factors associated with lower odds of receiving pharmacotherapy included speaking languages other than English, being male, and identifying as racial and ethnic minorities. CONCLUSIONS: Health system interventions could close the gap in access to smoking cessation services for unhoused and racial/ethnic minority patients in safety-net settings, thereby increasing cessation among these populations.

RESUMEN

INTRODUCTION: Nodding syndrome (NS) remains a poorly understood disorder. For a long time, it has been thought to be restricted to East Africa; however, cases in Central Africa have been increasing over time. The objective of this systematic review (SR) was to provide a summary of the state of knowledge on NS to date. METHODS: All original articles published on NS up to November 2021 were searched in four major databases and in the gray literature. Commentaries, editorials, book chapters, books, conference paper, qualitative studies that mentioned NS cases were also included. Data retrieved included study location (with GPS coordinates searched), year of study and publication, population characteristics, definition and diagnosis of NS, associated factors, and treatment if applicable. A meta-analysis of associated factors was performed where possible, and results were presented as odds ratios (ORs) and visualized as forest plots. Geographic information systems were used for cartographic representations. The quality of the articles included was assessed. RESULTS: Of the 876 articles initially identified, 67 (corresponding to 59 studies) were included in the SR. NS is only present in Central and East Africa. Interestingly, there were reports of NS in Central Africa prior to 2010, earlier than previously thought. The way NS diagnosis was established varies according to studies, and the 2012 WHO classification was used in only 60% of the studies. Approximately 11% of the articles did not meet the quality requirements set for this review. In our meta-analysis, the main factor associated with NS was onchocerciasis (OR = 8.8 [4.8, 15.9]). However, the pathophysiology of the disease remains poorly understood. The lack of common anti-epileptic drugs is a significant barrier to the management of head nodding and associated epileptic seizures. DISCUSSION/CONCLUSION: The lack of an operational definition of NS is an obstacle to its diagnosis and, thus, to its appropriate treatment. Indeed, diagnostic difficulties might have led to false positives and false negatives which could have altered the picture of NS presented in this article. Treatment should take into account nutritional and psychological factors, as well as associated infections. Some risk factors deserve further investigation; therefore, we suggest a multicentric study with an etiological focus using a more operational definition of NS.

RESUMEN

BACKGROUND: Maternal sepsis is the third leading cause of maternal death in the world. Women in resource-limited countries shoulder most of the burdens related to sepsis. Despite the growing risk associated with maternal sepsis, there are limited studies that have tried to assess the impact of maternal sepsis in resource-limited countries. The current study determined the outcomes of maternal sepsis and factors associated with having poor maternal outcomes. METHODS: A facility-based retrospective cross-sectional study design was employed to assess the clinical presentation, maternal outcomes, and factors associated with maternal sepsis. The study was conducted in Ayder Comprehensive Specialized Hospital, Tigray, Ethiopia, from January 1, 2017, to December 31, 2021. Sociodemographic characteristics, clinical characteristics and outcomes of women with maternal sepsis were analyzed using a descriptive statistic. The association between dependent and independent variables was determined using multivariate logistic regression. RESULTS: Among 27,350 live births, 298 mothers developed sepsis, giving a rate of 109 maternal sepsis for every 10,000 live births. There were 22 maternal deaths, giving rise to a case fatality rate of 7.4% and a maternal mortality ratio of 75 per 100,000 live births. Admission to the intensive care unit and use of mechanical ventilator were observed in 23.5% and 14.1% of the study participants, respectively. A fourth (24.2%) of the mothers were complicated with septic shock. Overall, 24.2% of women with maternal sepsis had severe maternal outcomes (SMO). Prolonged hospital stay, having parity of two and above, having the lung as the focus of infection, switchof antibiotics, and developing septic shock were significantly associated with SMO. CONCLUSIONS: This study revealed that maternal sepsis continues to cause significant morbidity and mortality in resource-limited settings; with a significant number of women experiencing death, intensive care unit admission, and intubation attributable to sepsis. The unavailability of recommended diagnostic modalities and management options has led to the grave outcomes observed in this study. To ward off the effects of infection during pregnancy, labor and postpartum period and to prevent progression to sepsis and septic shock in low-income countries, we recommend that concerted and meticulous efforts should be applied to build the diagnostic capacity of health facilities, to have effective infection prevention and control practice, and to avail recommended diagnostic and management options.

RESUMEN

BACKGROUND: Diarrhea is a serious health problem in children under the age of five that is both preventable and treatable. In low-income countries like Ethiopia, children under the age five years frequently experience diarrhea. However, the burden and associated factors of these diarrheal diseases are understudied in Eastern Ethiopia, Thus, this study aimed to determine the factors associated with the prevalence of diarrheal diseases in Eastern Ethiopia from September 1-30, 2022. METHODS: A cross-sectional study was conducted on the total of 602 children aged 6 to 59 months in Oda Bultum district in eastern Ethiopia. A multistage sampling method was used. Three kebeles were selected from nine kebeles by the lottery method. Data was entered into Epi data 4.0.2 and exported to SPSS version 21 for analysis. Descriptive analysis was used for frequency, mean, and standard deviations. In addition, bivariable, and multivariable Poisson regression model was used to identify predictors of diarrhea along with a 95% confidence interval. Finally, statistical significance was declared at a p-value of 0.05. RESULT: A total of 602 children were included in this study. The prevalence of diarrhea 7.4% (47/602), 95% CI; 5.5-9.7%) among the children. Factors such as being unvaccinated for any vaccine (AOR = 10.82, 95%CI; 4.58-25.48) and born from a mother who had medium level of empowerment (AOR = 0.34, 95%CI; 0.11-0.88) in the household had statistically significant association with diarrhea among the children compared to their counterparts. CONCLUSION: The study found that nearly one out of thirteen children aged 6 to 59 months had any form of diarrheal diseases in Oda Bultum District, Eastern Ethiopia. In addition, the study revealed that children who were vaccinated for their age developed diarrhea less likely compared to those who did not receive any form of vaccine for their age. Moreover, children with mothers who had a medium level of empowerment were less likely to get diarrhea than children with mothers who had a low level of empowerment.

RESUMEN

BACKGROUND: Corona virus disease 2019 (COVID-19) is an extremely contagious viral infection caused by the severe acute respiratory syndrome coronavirus 2. Understanding the willingness of the community to receive the COVID-19 vaccine will help in the development and implementation of effective COVID-19 vaccination promotion programs. Therefore, we aimed to assess the level of COVID-19 vaccine acceptance and associated factors among residents of Dire Dawa Administration, Eastern Ethiopia. METHODS: A community-based cross-sectional study was conducted among 840 residents in Dire Dawa Administration from May 18th to June 18th, 2021. Multistage cluster sampling followed by systematic random sampling was used to select respondents. A pretested interviewer-administered structured questionnaire was used to collect the data from respondents. Bivariable and multivariable logistic regression were used to identify predictors of COVID-19 vaccine acceptance. The odds ratio (OR), along with a 95% confidence interval (CI), was used to estimate the strength of the association. RESULTS: Out of 840 respondents recruited, the proportion of COVID-19 vaccine acceptance was found to be 54.4% (457/840); (95% CI: 51.0%, 57.7%) Being male [AOR = 1.85, 95% CI: (1.35, 2.54), P < 0.001], not having a current habit of substance use [AOR = 2.38, 95% CI: (1.73, 3.26), P < 0.001], having a monthly income of less than 51.31 USD [AOR = 0.19, 95% CI: (0.04, 0.88), P = 0.001]; and not having a prior history of vaccination experience [AOR = 0.40, 95% CI: (0.29, 0.54), P < 0.001] were significantly associated with COVID-19 vaccine acceptance. CONCLUSION: This study reveals that the proportion of COVID-19 vaccine acceptance among residents of Dire Dawa Administration, Eastern Ethiopia, was 54.4%. Factors like being male and not having a current habit of substance use were positively associated, whereas having a monthly income of less than 51.31 USD and not having a prior history of vaccination experience were negatively associated with COVID-19 vaccine acceptance. Health information dissemination and economic empowerment are crucial to improving COVID-19 vaccine acceptance among the community. This study provides valuable data for policymakers to plan early vaccination programs and tackle the challenges identified in the study.

RESUMEN

BACKGROUND: Diabetes mellitus (DM) has a direct impact on the clinical manifestation and prognosis of active tuberculosis disease (TB) and is known to increase the chance of developing the condition. We sought to determine the prevalence of DM in adult Ugandan patients with recently diagnosed TB and the associated sociodemographic, anthropometric, and metabolic characteristics of TB-DM comorbidity. METHODS: In this cross-sectional study conducted at the adult TB treatment centres of three tertiary healthcare facilities in Uganda, we screened adult participants with recently diagnosed TB (diagnosed in < 2 months) for DM. All participants were screened with five tests; initially with a random blood glucose (RBG) test, and then later with fasting blood glucose (FBG), laboratory-based glycated hemoglobin (HbA1c), point-of-care (POC) HbA1c, and oral glucose tolerance test (OGTT) if the RBG was ≥ 6.1 mmol/l. The WHO guidelines for diagnosing and managing DM were used to support the DM diagnosis. To identify the factors associated with DM-TB comorbidity, logistic regression was used. RESULTS: A total of 232 participants with recently diagnosed TB were screened for DM. Of these, 160 (69%) were female. The median (IQR) age, body mass index, and RBG of all study participants was 35 (27-42) years, 19.2 (17.6-21.3) kg/m2, and 6.1 (5.5-7.2) mmol/l, respectively. About half of the participants (n = 117, 50.4%) had RBG level ≥ 6.1 mmol/l. Of these, 75 (64.1%) participants returned for re-testing. Diabetes mellitus was diagnosed in 32 participants, corresponding to a prevalence of 13.8% (95% CI 9.9-18.9). A new diagnosis of DM was noted in 29 (90.6%) participants. On logistic regression, age ≥ 40 years was associated with increased odds of TB and DM comorbidity (AOR 3.12, 95% CI 1.35-7.23, p = 0.008) while HIV coinfection was protective (AOR 0.27, 95% CI 0.10-0.74, p = 0.01). CONCLUSION: TB and DM comorbidity was relatively common in this study population. Routine screening for DM in adult Ugandan patients with recently diagnosed TB especially among those aged ≥ 40 years and HIV-negative patients should be encouraged in clinical practice.

RESUMEN

BACKGROUND: Psychotic disorders are prevalent among people with epilepsy compared to the general population. However, there is limited information regarding psychosis among people with epilepsy in Uganda. This study therefore determined the prevalence and associated factors of psychosis among adults with epilepsy attending Butabika National Referral Mental Hospital in Uganda. METHODS: This was a cross-sectional study involving adults with epilepsy. The diagnosis of psychosis was assessed using the Mini-International Neuropsychiatric Interview, module for Psychotic disorders. Logistic regression analysis identified factors associated with psychosis. RESULTS: Out of 250 participants, 6.8% had psychosis and 13.6% had depression. Psychosis was significantly associated with older age, greater perceived stigma and substance use. CONCLUSION: Psychosis affects nearly 7% of adults with epilepsy in Uganda especially among those who are older, with perceived stigma and substance use. Routine screening and early intervention to management of psychosis in PWE is highly recommended.

RESUMEN

BACKGROUND: Chronic heart failure affects approximately 26 million people globally. World Health Organization data show that only approximately half of chronically ill patients in developed countries adhere to recommended medication, with even lower rates in developing countries. Medication adherence is critical for managing chronic heart failure symptoms, delaying disease progression, and preventing hospitalizations. However, poor adherence increases rehospitalization, morbidity, mortality, and healthcare costs. OBJECTIVE: To assess medication adherence and associated factors among chronic heart failure patients on follow-up at North Shewa Public Hospitals, Oromia Region, Ethiopia, in 2023. METHODS: This institutional-based cross-sectional study was conducted from March 1 to April 30, 2023, G.C. A total of 603 individuals were selected consecutively among those who underwent chronic OPD after being proportionally allocated to five hospitals in the zone. The data were collected using an interviewer-administered questionnaire and a medical chart review. The data were entered into Epi-data version 3.1 and then exported to SPSS version 26 for analysis. The multivariable logistic regression model included variables with a P value < 0.25 in the bivariate analysis. The degree of association was expressed using an adjusted odds ratio (AOR) with a 95% confidence interval (CI) at a P value < 0.05. RESULTS: Among the 603 patients, 56% had optimal medication adherence, with a 95% CI of 52.1 to 60. Being able to read and write (AOR: 2.20; 95% CI: 1.34, 3.61), having a secondary education (AOR: 1.97; 95% CI: 1.06, 3.67), having community-based health insurance (AOR: 1.82; 95% CI: 1.22, 2.71), not having comorbidities (AOR: 1.82; 95% CI: 1.18, 2.52), taking several drugs < 2 (AOR: 2.11; 95% CI: 1.20, 2.45), not adding salt when cooking (AOR: 1.72; 95% CI: 1.20, 2.45), and asking a doctor or nurse without fear (AOR: 1.87; 95% CI: 1.03, 3.40) were factors associated with medication adherence among CHF patients. CONCLUSION: This study revealed that 56% of chronic heart failure patients had optimal medication adherence. Factors associated with higher adherence included higher education, community health insurance, lack of comorbidities, fewer medications, avoiding added salt, and comfortable communication with providers. Health professionals should provide education to strengthen medication adherence.

RESUMEN

BACKGROUND: Atrial fibrillation (AF) is a supraventricular arrhythmia associated with uncoordinated atrial activation. Atrial fibrillation is complication of rheumatic heart disease and is associated with substantial morbidity and mortality. It is a growing public health problem and economic and social burden. Studies investigating the prevalence and factors associated with atrial fibrillation among chronic rheumatic heart disease patients in Ethiopia are scarce. Therefore, this study aimed to determine the prevalence and factors associated with atrial fibrillation in patients with chronic rheumatic heart disease. METHODS AND MATERIALS: A hospital-based cross-sectional study was conducted. A total of 410 patients were selected using a systematic random sampling method. The data were entered into Epi-Data version 4.6 and subsequently exported to SPSS version 26 software for analysis. A binary logistic regression model was applied to identify significant variables related to AF. RESULTS: In this study, 410 patient charts were reviewed. The prevalence of atrial fibrillation was 43% (95% CI of 38% up to 48%). Male (AOR = 3.81, 95% CI 2.00-7.26), age greater than 30 years (AOR = 7.26, 95% CI 3.93-13.41), heart failure (AOR = 4.65, 95% CI 2.39-9.04), mitral valve stenosis (AOR = 6.36, 95% CI 2.92-13.87), and left atrial diameter enlargement (AOR = 3.41, 95% CI 1.64-7.09) were associated with atrial fibrillation. CONCLUSIONS AND RECOMMENDATIONS: Atrial fibrillation leads patients to frequent hospital admission and increases hospital mortality. As a result, health care professionals need to pay more attention to and apply more clinical treatment for older patients, those with heart failure, those with mitral valve stenosis, and those with left atrial diameter enlargement-associated causes of atrial fibrillation.

RESUMEN

INTRODUCTION: Globally, sleep disturbance is the foremost public health issue among pregnant women which might have undesirable birth outcome including neurocognitive impairment, preterm birth, low birth weight, and neonatal morbidity and mortality. In Ethiopia, inconsistent findings have been reported on the prevalence of sleep disturbance among pregnant women. Therefore, this review aims to estimate the pooled prevalence sleep disturbance and its associated factors among pregnant women in Ethiopia. METHODS: This systematic review and meta-analysis of observational studies was designed according to the PRISMA guideline. A systematic search of literature was conducted in PubMed, Scopus, Web of science, and Google Scholar using relevant searching key terms. The Newcastle-Ottawa scale was used to evaluate the quality of all selected articles. Data were analyzed using STATA Version 14 software. Publication bias was checked using Egger's test and funnel plot. Cochran's chi-squared test and I2 values were used to assess heterogeneity. A fixed-effects model was applied during meta-analysis. RESULTS: In this review, six studies were included after reviewing 17,100 articles. The pooled prevalence of sleep disturbance among pregnant women in Ethiopia was 50.43% (95%CI: 39.34-61.52). Third trimester pregnancy AOR = 4.03; 95% CI: 2.84,5.71), multigravidity (AOR = 1.99; 95% CI: 1.54, 2.59), unplanned pregnancy (AOR = 2.56; 95% CI: 1.52,4.31), depression (AOR = 3.57; 95% CI: 2.04, 6.27), stress (AOR = 2.77; 95% CI: 1.57, 4.88), anxiety (AOR = 3.69; 95% CI: 1.42, 9.59) and poor sleep hygiene (AOR = 2.49; 95% CI: 1.56, 3.99) and were statistically associated with sleep disturbance among pregnant women. CONCLUSION: This review revealed that the magnitude of sleep disturbance among pregnant woman in Ethiopia was relatively high and multiple factors determined the likelihood of having a disturbed sleep-awake pattern. Thus, the implementation of interventions for sleep disturbance after screening pregnant women is needed. Moreover, public health interventions targeted on the prevention of unintended pregnancy and depression during pregnancy should be implemented.

RESUMEN

BACKGROUND: This study aimed to survey the prevalence of depression and its associated factors among psychiatrists and psychiatry trainees (physicians in psychiatric residency training). METHODS: This cross-sectional study surveyed Thai psychiatrists and psychiatry trainees from January to February 2023 using an online questionnaire. The questionnaires consisted of (1) the demographic and work-related information; (2) perceptions towards social support and work; (3) the Patient Health Questionnaire-9 (PHQ-9) Thai version; and (4) the 6-item Revised UCLA Loneliness Scale Thai version. All data were analyzed using descriptive statistics, and the associated factors concerning depression were analyzed via multiple linear regression analyses. RESULTS: Of the 225 total participants, 52(23.1%) and 173 (76.9%) were psychiatry trainees and psychiatrists, respectively. Most of them were female (64.9%) with overall median age (interquatile) was 34 (30, 42) years. Regarding the PHQ-9 findings, the prevalence of depression among all participants was 12.4% (psychiatrists 13.9% and psychiatry trainees 7.7%). From regression analyses, depression was associated with loneliness and perceived levels of work satisfaction and work stress in psychiatrists, while in psychiatry trainees, depression was associated with loneliness and perceived level of ability to control work schedule. CONCLUSIONS: One-tenth of psychiatrists and psychiatry trainees had depression. Although the prevalence of depression in this study was not extremely high, key contributing factors related to depression, such as loneliness, work satisfaction, work stress, and ability to control the work schedule should be required to action to reduce the depression rate among mental health personnel.

RESUMEN

BACKGROUND: Since 2012, work-hour alcohol use (WHAU) has been prohibited in China. However, there is a lack of national data on WHAU among healthcare workers, including psychiatrists. METHODS: We collected data from psychiatrists in 41 tertiary psychiatric hospitals using an online questionnaire, which included demographics, work-related factors, WHAU, and the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C). RESULTS: Out of 2911 psychiatrists who completed the survey, 4.29% reported having heard (3.13%) or witnessed (1.17%) WHAU among colleagues, and .51% (95% CI: .26%-.78%) admitted to their own WHAU. Most participants (95.57%) reported awareness of the policy against WHAU. Poisson regression demonstrated the unawareness of WHAU policy (incidence-rate ratios [IRR] 11.08; 95% CI: 3.56-34.52; P < .001), lower income (IRR .87; 95% CI: .79-0.96; P = .008), and higher AUDIT-C scores (IRR 1.48; 95% CI: 1.22-1.80; P < .001) were significantly associated with WHAU occurrences. CONCLUSIONS: The survey indicates that WHAU among psychiatrists is more prevalent than expected, correlating with insufficient awareness of hospital policies. This suggests a need for targeted educational interventions.

RESUMEN

BACKGROUND: Thrombocytopenia in pregnancy is a common multifactorial abnormality of the hematological system, next to anemia. It leads to more increased risk of bleeding during delivery, labour, or the postpartum period. Despite being a significant public health concern, there are limited studies done concerning thrombocytopenia during pregnancy. OBJECTIVE: To assess the magnitude and associated factors of thrombocytopenia among pregnant women at Mizan Tepi University Teaching Hospital from September 2023 to November 2023. METHODS: An institutional-based cross-sectional study was carried out on 230 systematic randomly selected pregnant women who attended antenatal visits from September 2023 to November 2023 G.C using data collection tools. The pretested structured questionnaires were employed to obtain clinical, nutritional, and sociodemographic information. Additionally, three millilitres of venous blood were collected from each participant and analyzed using a Sysmex hematology analyzer. The data was entered into Epidata version 4.6 and analyzed using STATA version 14. Descriptive statistics were computed, and logistic regression was used to identify predictors with a significance level of less than 0.05. RESULTS: Two hundred thirty pregnant women participated in the study. Among study participants, the magnitude of thrombocytopenia was 55(24.35%) with 32 (57.14%) mild, 19 (33.93%) moderate, and 5 (8.93%) severe thrombocytopenia. The determinant factors which shown significant association were Malaria parasite infection (AOR 9.27 at 95% CI 7.42, 10.87), one-year Inter-birth interval (AOR 1.7 at 95% CI 1.24, 2.14), History of abortion (AOR 3.94 95% CI 3.13, 4.86), History of hypertension (AOR 3.12 95% CI 1.56, 4.12), HIV infection (AOR 1.81 95% CI 1.32.2.52) and HBV infection (AOR 3.0 95% CI 2.82, 3.34). CONCLUSION: Thrombocytopenia is a public health problem and mild type of thrombocytopenia was the most predominant. The determinant factors that showed significant association with thrombocytopenia were Malaria Parasitic infection, one-year Inter-birth interval, History of abortion, History of hypertension, HIV infection, and HBV infection. Therefore, pregnant women should be continuously screened for thrombocytopenia to avoid excessive bleeding. Increasing Inter-birth interval, preventing abortion as well as timely diagnosis and treatment of underlying causes such as malaria infection, hypertension, HBV, and HIV is important to reduce the burden of thrombocytopenia.

RESUMEN

BACKGROUND: The Continuum of care for reproductive, maternal, newborn, and child health includes integrated service delivery for mothers and children from pre-pregnancy to delivery, the immediate postnatal period, and childhood. In Ethiopia, the magnitude of antenatal care, skilled delivery, postnatal care, and immunization for children have shown improvement. Despite this, there was limited research on the percentage of mothers who have completed maternal and child continuum care. OBJECTIVE: To assess the Completion of Maternal and Child Health Continuum of Care and Associated Factors among women in Gode District, Shebele Zone, Eastern Ethiopia ,2022. METHOD: A community-based cross-sectional study design applied from November 1-15, 2022. A stratified sampling method was applied. A woman who had two 14-24 months child preceding the data collection period were included in the study. An interviewer-administered semi-structured questioner had been used for data collection. Data collected by using kobo collect and analyzed using STATA version 17. Both Bivariable and multivariable logistic regression analyses were done. In multivariable analysis, variables having P-values ≤ 0.05 were taken as factors associated with the completion of the maternal and child health continuum of care. RESULT: The Completion of maternal and child continuum of care was 13.5% (10.7-17.0%) in Gode district,2022. Accordingly, Husband occupation (Government employee) [AOR = 2.3, 95%CI 1.2-4.7] and perceived time to reach health facility (less than 30 min) [AOR = 2.96, 95%CI 1.2-7.5] were factors showing significant association with maternal and child health continuum of care among mothers in Gode district, Somali regional State;2022 at P-value ≤ 0.05. CONCLUSION AND RECOMMENDATION: Only 13.5% of mothers in Gode district received all of the recommended maternal and child health services during their pregnancy, childbirth, and postpartum period. The study found that two factors were associated with a higher likelihood of receiving Maternal and child continuum of care: Government employed husband and perceived time to reach a health facility. Governments can play a key role in increasing the maternal and child health continuum of care by investing by making health care facility accessible.

RESUMEN

BACKGROUND: The immediate postpartum period is a very crucial phase for both the life of the mother and her newborn baby. Anemia is the most indirect leading cause of maternal mortality. However, anemia in the immediate postpartum period is a neglected public health problem in Ethiopia. Therefore, this systematic review and meta-analysis aimed to estimate the pooled magnitude of immediate postpartum anemia and the pooled effect size of associated factors in Ethiopia. METHODS: Searching of published studies done through PubMed, Medline, Cochrane, African index Medicus, List of Reference Index, Hinari, and Google Scholar. This systematic review and meta-analysis follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) godliness. The quality of studies was assessed by using a Newcastle- Ottawa Scale (NOS) assessment tool. Analysis was performed using a random effect model by using STATA 17 version software. Egger's weighted regression and I2 test were used to evaluate publication bias and heterogeneity respectively. RESULTS: In this systematic review and meta-analysis, a total of 6 studies were included. The pooled magnitude of immediate postpartum anemia in Ethiopia was 27% (95%CI: 22, 32). Instrumental mode of delivery (OR = 3.14, 95%CI: 2.03, 4.24), mid-upper arm circumference (MUAC) measurement < 23 cm (OR = 3.19, 95%CI: 1.35, 5.03), Antepartum Hemorrhage (OR = 4.75, 95%CI: 2.46, 7.03), postpartum hemorrhage (OR = 4.67, 95%CI: 2.80, 6.55), and no iron/foliate supplementation (OR = 2.72, 95%CI: 1.85, 3.60) were the identified factors associated with developing anemia in the immediate postpartum period. CONCLUSION: The overall pooled magnitude of anemia in the immediate postpartum period among Ethiopian women was still a moderate public health problem. Instrumental mode of delivery, mid upper arm circumference (MUAC) measurement < 23 cm, antepartum hemorrhage, postpartum hemorrhage, and no iron/foliate supplementation were the identified factors associated with higher odds of developing anemia among immediate postpartum women in Ethiopia. Therefore, midwives, and doctors, shall focus on prevention of maternal hemorrhage, nutritional advice and counseling including iron /foliate supplementation, and avoid unnecessary instrumental delivery to prevent and reduce anemia related maternal mortality and morbidity in Ethiopia.

RESUMEN

INTRODUCTION: The annual global burden of stillbirths is estimated to be 3.2 million, of which 98% occur in low and middle-income countries (LMICs). In the Amhara region of Ethiopia, the prevalence of stillbirth outcomes was 85 per 1000. Ethiopia is experiencing an increase in the number of health professionals attending deliveries, however, stillbirth rates are not decreasing as anticipated. However, there are limited numbers of studies done related to the proportion of stillbirths and associated factors in the study area. This study aimed to assess the proportion of stillbirths and associated factors among women who attended deliveries at Tibebe Ghion Specialized Hospital and Felege Hiwot Comprehensive Specialized Hospital. METHODS: An institutional-based cross-sectional study was conducted on 366 women who delivered at two referral hospitals in Bahir Dar from April 1, 2020, to August 30, 2020. Study participants were selected using systematic random sampling techniques. A checklist and structured questionnaire were used to retrieve information from the clients and their attendants. The collected data were cleaned, coded, and entered into Epi-data version 3.1 and then exported into SPSS 23 for analysis. Bivariate and multivariable logistic regression analysis was computed to identify statistically significant associated factors with a P value < 0.05. The results were presented in tables and charts. RESULT: The proportion of stillbirths was 3.8% in this study area. This study showed that level of education, who completed primary school (AOR = 0.12; 95% CI (0.01, 0.98)), not using partograph (AOR = 3.77, 95%; CI (1.02; 13.93)), and obstetric complication (AOR = 6.7; 95% CI (1.54, 29.79) were the major factors affecting the stillbirth. CONCLUSION: Our study found that stillbirth rate remains a major public health problem. Illiteracy, not using a partograph, and having obstetric complications were major associated factors for stillbirth. The risk factors identified in this study can be prevented and managed by providing appropriate care during preconception, antepartum, and intrapartum periods.

RESUMEN

BACKGROUND: Abnormal uterine bleeding, a frequent gynecological problem among women of reproductive age, significantly affects their health and quality of life. Despite its problem, research on its extent and contributing factors in Ethiopia is scarce. Hence, this study is designed to determine the magnitude and factors associated with abnormal uterine bleeding among women visiting Dilla University General Hospital, Dilla, Ethiopia. METHODS: A cross-sectional study design was conducted with 380 women of reproductive age at Dilla University General Hospital. A systematic sampling method was employed to select the participants for the study. A structured interview administered questionnaire and checklist were used to collect the data. Stata V.14 software was used for cleaning, coding, ensuring completeness and accuracy, and further analysis. Bivariate and multivariable logistic regression analyses were used. Finally, the variables that have a p-value of < 0.05 were considered statistically significant. RESULTS: In this study, the magnitude of abnormal uterine bleeding was 24.21% (95% CI, 20.14-28.79). History of sexually transmitted disease [AOR = 1.44, 95% CI: (1.33, 4.75)], history of anemia [AOR = 3.92, 95% CI: (1.20, 12.74)]., history of alcohol consumption [AOR = 2.49, 95% CI: (1.22, 5.06)], and perceived stress level [AOR = 1.30, 95% CI: (1.15, 1.69)] were found to be significantly associated with abnormal uterine bleeding. CONCLUSIONS: The magnitude of abnormal uterine bleeding was 24.2% in the study setting. Factors such as a history of sexually transmitted disease, anemia, alcohol consumption, and perceived stress level were identified as significant risk factors for abnormal uterine bleeding. Addressing these factors is crucial for management. Further research and interventions targeting these risks are needed to enhance health outcomes. The study provides valuable insights for future interventions.
