Survival status and predictors of mortality among cervical cancer patients at oncologic centers in Addis Ababa, Ethiopia: a follow up study.

BACKGROUND: Cervical cancer (CC) ranks as the third most commonly diagnosed cancer and the fourth leading cause of cancer-related deaths among women globally. In Addis Ababa, there is a shortage of available evidence concerning the phenomenon of survival time and its predictors among women diagnosed with CC. Therefore, this study aimed to assess the survival status and predictors of mortality among CC patients at oncologic centers in Addis Ababa, Ethiopia. METHODS: A facility-based retrospective cohort study was conducted among records of women with cervical cancer enrolled from the 1st of January 2017 to the 30th of December 2022 among 252 cervical cancer patients. Data were collected using a pretested, structured data collection checklist by trained data collectors. The Kaplan-Meier survival curve was used to estimate the survival time of the respondents. The Cox multivariable regression model was carried out to identify predictors of CC. Variables with P-value < 0.05 in multivariable analysis were declared as statistically significant. RESULTS: The cumulative proportion of surviving at the end of the 10th and 20th month was 99.6% (95%CI: 97.02, 99.94) and 96.99% (95%CI: 93.41, 98.64), respectively. Similarly, it was 92.67% (95%CI: 87.65, 95.70), 85.9% (95%CI: 78.68, 90.94), 68.0% (95%CI: 57.14, 76.66) and 18.27% (8.38, 31.16) at the end of 30th, 40th, 50th and 60th monthly respectively. The overall median survival time was 54 months (95%CI: 52.6, 55.4). The incidence of death among a cohort of women with CC was 7.34 per 1000 person months. Being anemic (AHR: 4.77; 95%CI: 1.93, 11.77; P-value: 0.001), took a single cancer treatment (AHR: 1.92; 95%CI: 1.01, 3.64; P-value: 0.046) and HIV sero status positive (AHR: 2.05; 95%CI: 1.01, 4.19; P-value: 0.048) were statistically significant in multivariable cox proportional hazard model. CONCLUSION AND RECOMMENDATION: Anemia, treatment initiation and HIV-sero status were independent predictors of mortality among women admitted with CC. It is imperative to enhance early screening initiatives and treatment resources for CC, alongside fostering public awareness through collaboration with various media outlets concerning preventive measures, screening procedures, and treatment alternatives for CC.

Survival Status and Predictors Among Women with Advanced Stage of Cervical Cancer.

Background: Cervical cancer is one of the leading causes of cancer death in women, even though it is a preventable disease. Most deaths occur in low- and middle-income countries. In addition to early detection and receipt of standard treatments, survivorship is an important component of high quality of care across the cancer continuum. Objective: To assess the survival status of advanced-stage cervical cancer patients after cancer treatment has started. Methods and Materials: A one-year prospective cohort study was employed to assess the survival status of women with advanced stages of cervical cancer. A total of 180 cervical cancer patients were recruited, and the study was conducted from January 10, 2022, to September 20, 2023. Data entry and analysis were done in the SPSS 29 version. Descriptive statistics were used to examine participant characteristics. The Kaplan-Meier procedure and log rank test were used to estimate the duration of survival. Bivariate and multivariate Cox regression analyses were computed for predictor variables with survival status. Results: Patients receiving cancer treatment at FIGO stages IVA and IVB had survived by 56% and 24%, respectively, whereas patients receiving treatment at stages IIB and IIIA had survived by 100%. The estimated mean survival time at one-year follow-up was 5.706 months (95% CI: 3.785-7.627) for patients with FIGO stage IVB, but 11.537 months (95% CI: 11.199-11.887) for those with stages II and III (P < 0.001). Women over 60 years old had a 1.5-fold higher risk of death than those under 60 (HR: 1.482, P = 0.040). Conclusion: The one-year cumulative survival rate among advanced-stage cervical cancer patients was 77%. Major factors associated with survival were age, cancer stage, the presence of anemia, and waiting time for treatment.

Time to death and its determinants of under-five children in rural Ethiopia by using shared frailty.

Under-five (U5M) is one of the most significant and sensitive measures of the community's health. Children who live in rural areas are more likely than those who live in urban areas to die before the age of five. Therefore, the study aimed to assess the Survival status of under-five mortality and its determinants in rural Ethiopia. The 2019 Ethiopia Mini Demographic and Health Survey was used in this study as a secondary source (EMDHS). A total of 4426 weighted under-five children were included in the study. To determine survival time and identify predictors of death among children under the age of five, the Cox's gamma shared frailty model and the Kaplan Meier model, respectively, were used. An adjusted Hazard Ratio (AHR) along with a 95% Confidence Interval (CI) were used to measure the size and direction of the association. The Study showed that in rural Ethiopia, 6.03% of children died before celebrating their first birthday. The median age of under-five mortality in rural Ethiopia was estimated to be 29 Months. The hazard of death among under-five children and those who had given birth to two children in the last five years was 4.99 times less likely to be at risk of dying than those who had given birth to one Child in the previous five years (AHR 4.99, 95% CI 2.97, 8.83). The Study Concluded that under-five mortality remained high in rural Ethiopia. In the final model, the Age of Mothers, Sex of Household, Breastfeeding, Types of Birth, Sex of Child, Educational Level of Mothers, Wealth Index, Child ever born, Marital Status, and Water Source were significant predictors of under-five mortality. Twins and children who are not breastfed should receive additional attention, along with improving water resources for households and mothers income.

Survival Status and Predictors of Tuberculosis Development Among Under 5 Children Admitted With Severe Acute Malnutrition in Ethiopia: A Retrospective Cohort Study.

Introduction. The burden of severe acute malnutrition (SAM) remains unacceptably high worldwide. The burden of Tuberculosis (TB) co-occurring with SAM in under 5 children is a significant focus for the improvement of child health. The co-existence of these diseases are significantly enhancing the associated morbidity, mortality, and hospitalization costs among this population. Objective. To determine survival status and predictors of TB development in under 5 children with SAM in Asella Referral and Teaching Hospital, Ethiopia. Methods. A retrospective cohort study was done in 247 under 5 children with SAM between January 01/2018 and December 31/2022. Systematic sampling technique was used to select the study participants. Data extraction format was used to collect data from the patient's medical chart. EpiData version 4.6.0.6 was used for data entry and exported to STATA version 14.2 for statistical analysis. Result. This study includes 247 under 5 children with SAM with a response rate of 100%. Regarding to the survival status; 24(17%) of under 5 children with SAM have developed the events (TB) and the rest of them, 205(83%) were censored. The incidence density rate (IDR) of TB in under 5 children with SAM was 45.51 per 100 (95% CI: 33.63, 61.58) children-months observation. The cumulative incidence of TB was 17% (95% CI: 12.79, 22.25). Multivariable Cox proportional hazard analysis revealed that: having a history of TB contact (AHR = 5.56, 95% CI: 2.77, 11.15, P-value = .000), having a history of bottle feeding (AHR = 4.95, 95%CI: 1.08, 22.77, P-value = .040), did not take F100 (AHR = 1.71, 95% CI: 1.12, 7.25, P-value = .00) were statistically significant predictors of TB development. Conclusion. This study shows that the IDR of TB was high. Having a history of TB contact, history of bottle feeding, and not taking F100 were significant predictors of TB development. It is vital to address these predictors to prevent the development of TB in this population. Moreover, early screening of TB in these children should get high emphasize.

Experimental study on the purification capacity of potted plants on low-concentration carbon monoxide in indoor environment.

Indoor low-concentration carbon monoxide (CO) exposure is widespread worldwide, and potted plants may be a potential means for CO purification. The objective is to evaluate common indoor plants' CO purification and tolerance capacities. Epipremnum aureum (Linden ex André) G.S.Bunting, Chlorophytum comosum (Thunb.) Jacques, Spathiphyllum kochii Engl. & K.Krause, and Sansevieria trifasciata Hort. ex Prain with similar sizes were tested in the glass chamber with initial CO concentrations of 10, 25, 50, 100, 200, and 400 ppm, respectively. (1) The CO purification capacity of the four potted plants is ranked as Epipremnum aureum (Linden ex André) G.S.Bunting > Chlorophytum comosum (Thunb.) Jacques > Spathiphyllum kochii Engl. & K.Krause > Sansevieria trifasciata Hort. ex Prain. Under the purification effect of each plant, the CO concentration in the chamber decreases linearly and significantly (p < 0.05), and within a specific time period, the time-weighted average (TWA) CO concentrations can be reduced to below the corresponding permissible exposure limits specified by some countries and organizations. (2) With the increase of the stomatal number of each plant and the increase in CO concentration, the hourly and cumulative absorbed CO of each plant increase linearly and significantly (p < 0.05). (3) With the increase in CO concentration, the CO purification efficiency of each plant decreases exponentially and significantly (p < 0.05). (4) When the CO concentration was ≤ 50 ppm, all plants could effectively purify CO without damage. When the CO concentration was in the range of 100 ~ 400 ppm, within 2 weeks after the 48-h experiment, the leaf tips of Chlorophytum comosum (Thunb.) Jacques and Epipremnum aureum (Linden ex André) G.S.Bunting were damaged one after another, and the damaged leaf area increased with the increase of CO concentration. However, each plant as a whole still survived. This study demonstrated that different species of potted plants can effectively absorb low concentrations of CO to varying degrees, but higher concentrations of CO will damage the survival of specific species of potted plants.

Incidence and predictors of hypertension among diabetic patients attending a diabetic follow-up clinic in Ethiopia: a retrospective cohort study.

OBJECTIVE: To assess the incidence and predictors of hypertension among patients with diabetes attending a diabetes follow-up clinic. METHODS: This institution-based retrospective cohort study was conducted among patients with diabetes who attended a diabetic follow-up clinic at Asella Referral and Teaching Hospital between January 2017 and December 2021. Patients diagnosed with hypertension prior to diabetes, or diagnosed with hypertension at the start of follow-up, were excluded. Data were extracted from medical records and analysed. RESULT: A total of 351 patients with diabetes were included. The incidence density rate (IDR) of hypertension during 688.98 person-years of observation was 58.05 per 1000 (95% confidence interval [CI] 42.58, 79.14) person-years. The cumulative incidence of hypertension was 11.4% (95% CI 8.05, 14.7%) over 5 years. The 25th percentile survival time to hypertension development was 4.6 years. Multivariable Cox proportional hazard regression analysis showed that older age (adjusted hazard ratio [HR] 6.24, 95% CI 3.13, 12.45), family history of hypertension (adjusted HR 1.67, 95% CI 1.22, 9.65), comorbidity (adjusted HR 2.20, 95% CI 1.94, 5.21) and higher body mass index (adjusted HR 2.07, 95% CI 1.23, 5.63) were statistically significant predictors of hypertension development. CONCLUSION: Among patients with diabetes in Ethiopia, the IDR of hypertension was high; and older age, family history of hypertension, comorbidity and higher body mass index were statistically significant predictors of hypertension development.

Incidence and predictors of mortality in children with diabetic ketoacidosis in the comprehensive specialized referral hospitals of West Amhara Region, Northwest Ethiopia: a retrospective follow-up study.

Background: Diabetic ketoacidosis is one of the major life-threatening conditions associated with acute metabolic complications. It remains a major public health problem in developing countries such as Ethiopia. Objective: To assess the incidence and prediction of mortality in children with diabetic ketoacidosis in West Amhara Region Comprehensive Specialized Referral Hospitals, Northwest Ethiopia, in 2022. Methods: An institution-based retrospective follow-up study was conducted among 423 study participants with a confirmed diagnosis of diabetic ketoacidosis from 01/01/2017 to 31/12/2021. Data were entered, coded, cleaned, and checked using Epi-Data version 4.6 and exported to Stata version 14 for data analysis. Results: A total of 401 child records were included in the final analysis and were followed for 3781 days during the study period. The overall mortality of children with diabetic ketoacidosis was 10.6 per 1000 person-days observed (95% CI: 7.8-14.4) during the entire follow-up period. Hypoglycemia (AHR=4.6; 95% CI: 2.13-10.1), rural residence (AHR=2.9; 95% CI=1.01-8.11), age younger than five (AHR=4.4; 95% CI=1.4-13.7) or between five and 10 (AHR=3.1; 95% CI=1.1-8.8), and female gender (AHR=2.6; 95% CI=1.1-5.8) were significant predictors of mortality. Conclusions: The incidence rate of mortality in children with diabetic ketoacidosis was relatively high. Age, rural residence, female gender, and hypoglycemia were significantly predictive of mortality. Community education or mass campaigns about the signs and symptoms of diabetic ketoacidosis may reduce the mortality rate in children.

Survival status and predictors of mortality from severe community-acquired pneumonia among under-five children admitted at Debre Tabor comprehensive specialized hospital: a prospective cohort study.

Background: Globally, Pneumonia continues to be the leading cause of mortality among under-five children. Ethiopia ranks fourth out of 15 countries worldwide in terms of the highest death rate of under-five children due to severe community-acquired pneumonia (SCAP). However, to date, there is no recent study that shows survival status and predictors of mortality from SCAP. Therefore, this study aimed to determine survival status and predictors of mortality from this dangerous disease among under-five children. Methods: A facility-based prospective cohort study was conducted from 1 November 2021 to 31 October 2022 at Debre Tabor comprehensive specialized hospital. All under-five children with SCAP admitted during the study period were included. Participants were selected using a systematic sampling technique. The collected data were coded, edited, and entered into epi-data version 4.2 and then exported to STATA version 17 for further analysis. The Kaplan Meier failure estimate with log-rank test was employed to determine the survival estimates. A cox-proportional hazard regression model was fitted to identify significant variables. Results: The overall incidence density rate of mortality was 5.7 /1000 children with a median hospital stay of 8.2 days. Heart disease (AHR: 4.37; 95%CI: 1.68-11.32), previous admission of SCAP (AHR: 3.87; 95% CI: 1.31-11.43), WFL < -3Z score (AHR: 3.57; 95% CI: 1.02-12.42), impaired consciousness level at admission 3.41(1.14-10.19), and pleural effusion (AHR: 3.42; 95%CI: 1.18-9.93) were significant predictors of mortality. Conclusion: In this study, the survival probability of children with SCAP was low. Children with heart disease, previous admission of SCAP, WFL < -3Z score, impaired consciousness level at admission, and pleural effusion had low survival. Therefore, much emphasis is needed on children with SCAP, particularly those with identified predictors.

Survival Status and Predictors of Mortality Among Patients Admitted to Pediatric Intensive Care Unit at Selected Tertiary Care Hospitals in Ethiopia: A Prospective Observational Study.

Background: Advances in pediatric intensive care have dramatically improved the prognosis for critically ill patients. The study aimed to determine the survival status and predictors of mortality among patients admitted to the pediatric intensive care unit at selected tertiary care hospitals in Ethiopia. Methods: A health facility-based prospective observational study from October 2020 to May 30, 2021, was conducted in a selected tertiary care hospital in Ethiopia. Kaplan Meier was used to compare patient survival experiences and Cox regression was used to identify independent predictors of ICU mortality. The hazard ratio was used as a measure of the strength of the association, and a P-value of <.05 was considered to declare statistical significance. Results: Of 206 study participants, 59 (28.6%) patients died during follow-up time, and the incidence of mortality was 3.6 deaths per 100 person-day observation (95% CI: 2.04-5.04 deaths per 100 person-days). Respiratory failure 19 (32.2%) was the commonest cause of death followed by septic shock 11(18.6). In-ICU complications (AHR: 2.13; 95% CI: 1.02, 4.42; P = .04), sepsis diagnosis (AHR: 2.43; 95% CI: 1.24, 4.78; P = .01), GCS < 8 (AHR: 1.96; 95% CI: 1.12, 3.43; P = .02), use of sedative drugs (AHR: 2.40; 95% CI: 1.16, 4.95; P = .02) were linked with increased risk of in-ICU mortality. In contrast, the use of mechanical ventilation was associated with decreased mortality (AHR: 0.45; 95% CI: 0.21, 0.92; P = .03). Conclusion: The study found a high incidence of in-ICU mortality among admitted pediatric patients in selected Ethiopian tertiary care hospitals. In-ICU complications, sepsis diagnosis, GCS < 8, and patient use of sedative drugs were independent predictors of in-ICU mortality. Prudent follow-up is warranted for those patients with the aforementioned risk factors.

Survival Analysis and Its Predictors Among Hemodialysis Patients at Saint Paul Hospital Millennium Medical College and Myungsung Christian Medical Center in Addis Ababa, Ethiopia, 2021.

Background: Diabetes mellitus and hypertension are the most prominent conditions causing chronic kidney disease and eventually end-stage renal disease. Renal replacement therapy, particularly hemodialysis (HD), is the mainstay of treatment. The aim of this study is to assess the overall survival status of HD patients and potential survival predictors at Saint Paul hospital millennium medical college (SPHMMC) and Myungsung Christian Medical Center (MCM) in Addis Ababa, Ethiopia. Methods: A retrospective cohort study was conducted on HD patients at SPHMMC and MCM general hospital from January 1, 2013 to December 30, 2020. Kaplan Meier, Log-rank, and Cox proportional regression models were used for the analysis. Estimated risks were reported as hazard ratios with 95% confidence intervals and P<0.05 was considered as having a significant association. Results: A total of 128 patients were included in the study. Median survival time was 65 months. The predominant co-morbid condition was found to be diabetes mellitus with hypertension (42%). The total risk time for these patients was 143,617 person years. The overall incidence rate of death was 2.9 per 10,000 person years (95% CI=2.2-4). Patients who developed blood stream infection were 2.98-times more likely to die than those without infection. Those using an arteriovenous fistula were 66% less likely to die than those using a central venous catheter. Additionally, patients treated in a government-owned facility were 79% less likely to die. Conclusion: The study identified that the median survival time of 65 months was comparable with developed nations. Significant predictors of death were found to be blood stream infection and type of vascular access. Government-owned treatment facilities showed better patient survival.

Survival status and predictors of mortality among children who underwent ventriculoperitoneal shunt surgery at public hospitals in Addis Ababa, Ethiopia.

Background: Despite the increase in ventriculoperitoneal shunt surgeries performed for children with hydrocephalus, the potential complications and survival of patients after the procedure remains the major challenge for both clinical and public health aspects. This study intends to assess the survival status and scrutinize the predictive factors of mortality among children after a ventriculoperitoneal shunt.Methods: A retrospective cohort study was employed by reviewing charts of 337 systematically selected children who have undergone a ventriculoperitoneal shunt from 2016 to 2018 in Addis Ababa. The extraction tool was used for data collection, Epi-data version 4.4.2 for data entry, and Stata version-14 for cleaning and analysis. Kaplan-Meier curve, log-rank test, and life table were used to describe the data. Cox proportional hazard regression model was used for analysis. Any variable at p < 0.25 in the bi-variable analysis was fitted to multivariate analysis, and significance was declared at p ≤ 0.05. Then, AHR with 95% CI was used to report the association and test the statistical significance. Finally, texts and tables were used to present the results.Results and Conclusion: The incidence rate of mortality was 58.4 per 1000 child-months of observation with a median survival time of 12 months (95%CI: 9.04-14.96). Communicative hydrocephalus (AHR: 1.99, 95% CI: 1.18-3.36), post-traumatic brain injury (AHR: 7.43, 95% CI: 3.21-16.88), emergency surgery (AHR: 1.86, 95% CI: 1.17-3.13) as well as revised shunt procedure (AHR: 8.01, 95% CI: 6.12-13.43) were independent predictors of death. Besides, sunset eye (ARH: 2.01; 95% CI: 1.17-3.47), rapidly increased head size (ARH: 2.05, 95% CI: 1.14-3.37), prolonged antibiotics treatment (AHR: 2.46, 95% CI: 1.82-7.37), and gram-negative infections (AHR: 1.95, 95% CI: 1.60-12.64) were also significantly associated. Hence, health professionals ought to give special attention to patients with identified predictors.

The comparison of Lobe-Specific or Systematic Mediastinal Lymph Node Dissection for Early-Stage Lung Adenocarcinoma With Consolidation Tumor Ratio Over 0.5.

INTRODUCTION: Surgery is the most effective treatment for early-stage lung cancer. This study will propose a personalized plan for mediastinal lymph node dissection in early-stage lung adenocarcinoma to reduce the risk of surgery and improve the quality of life. METHODS: This study retrospectively analyzed the patients underwent lobectomy and lymph node dissection in the Department of Thoracic Surgery, Zhongshan Hospital, Fudan University. Clinical stage I lung adenocarcinoma patients with solid component ratio (CTR) between 0.5 and 1 were included. Patients were divided into systematic (S-MLND) and lobe-specific (L-MLND) mediastinal lymph node dissection groups. The days of hospitalization, the presence or absence of complications, the recurrence-free survival rate, and the overall survival rate were calculated to evaluate the postoperative quality and operation risk of the patients. RESULTS: 210 patients (138 L-MLND and 72 S-MLND) were included. 2 lymph node metastases appeared in the S-MLND group while none in the L-MLND group (P = .049). No differences were shown in age, tumor site, size, solid component, degree of tumor invasion, and stage. The proportion of patients with severe postoperative cough and the length of hospital stay in the L-MLND group decreased. The 5-year OS of the entire cohort was 98.1%, 98.6% in L-MLND, compared with 97.2% in S-MLND; RFS was 94.8%, 95.7% in L-MLND, compared with 93.0% in S-MLND. CONCLUSION: For cIA lung adenocarcinoma, according to the Thin-slice CT within 1 month before the operation, if the main lesion was less than 3 cm and CTR over 0.5, L-MLND is as effective as S-MLND.

A retrospective analysis of occupational pneumoconiosis in Zibo City from 1949 to 2021 / 中国职业医学

Objective: To analyze the base incidence, distribution characteristics, survival status and social security of occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") in Zibo City. Methods: The new pneumoconiosis patients in Zibo City from 1949 to 2021 were selected as the research subjects using a cross-sectional survey. Household survey or telephone follow-up were carried out, and the distribution characteristics, living conditions and social security situation were retrospectively analyzed. Results: A total of 8 910 patients with pneumoconiosis were investigated, and 96.0% of them were male. The stage Ⅰ pneumoconiosis patients accounted for 91.3%. From 1949 to 2021, the number of pneumoconiosis patients showed a stepwise upward trend with time. Most of the patients suffered from coal worker pneumoconiosis and silicosis, which accounted for 48.7% and 38.9%, respectively. The average age of onset was (52.7±11.4) years, and the average length of service exposed to dust was (21.1±9.4) years. The patients were concentrated in Zichuan District, Boshan District and Zhangdian District, that accounted for 87.8%. The industry distribution was mostly mining industry and manufacturing industry, accounting for 61.1% and 31.6% respectively. Among the 8 910 cases of pneumoconiosis, 543 cases were lost in follow-up. A total of 8 367 patients were followed-up, with a follow-up rate of 93.9%. The mortality rate of patients who completed follow-up was 50.5%, and the mortality rate decreased with the increase of the stage of pneumoconiosis (P<0.01). The rate of adoring social security in the 4 138 surviving patients was 98.4%. Conclusion: The situation of prevention and treatment of pneumoconiosis in Zibo City is challenging. It is necessary to strengthen the special control of dust hazards in mining and manufacturing industries in key areas such as Zichuan District, Boshan District and Zhangdian District.

Event History Analysis of Factors Affecting Survival of Older Adults in Taiwan.

(1) Background: Due to rapidly increasing average age of Taiwan's population, it is very important to analyze the factors affecting the survival of older adults. (2) Methods: In this study, the 1989 Taiwan Longitudinal Study on Aging, which lasted 22 years and consisted of seven surveys, was used. Furthermore, Cox and Aalen's time-dependent frailty models were used to analyze factors that affect the survival of older adults. (3) Results: Based on past literature, we selected 15 important factors that were closely associated with the survival of older adults and constructed six models based on these factors. The study results showed that, in addition to background characteristics, physical and mental conditions, activities of daily living (ADL), physical performance, and self-rated health had a huge association with the survival of older adults. (4) Conclusions: We selected ten variables (age, gender, population, education level, ADL status, physical performance, self-rated health, smoking, chewing betel nut, and the presence of a spouse), and their combinations were used to generate reduced models, which could be considered as important markers that affect and predict the survival of older adults.

Survival time and predictors of death among HIV infected under five children after initiation of anti -retroviral therapy in West Amhara Referral Hospitals, Northwest Ethiopia.

BACKGROUND: Acquired immune deficiency syndrome is an infectious disease caused by the human immunodeficiency virus (HIV) that primarily targets an individual's immune system. In Ethiopia, nearly 24% of HIV-related deaths occur in children under the age of five. However, studies regarding the survival time of HIV-positive under-five children after anti-retroviral therapy initiation are limited with poor evidence of predictors of death. OBJECTIVE: To assess survival time and predictors of death among HIV infected under-five children after initiation of anti-retroviral therapy in West Amhara Referral Hospitals, Northwest Ethiopia, 2021. METHODS: A multicenter institution-based retrospective follow-up study was conducted among 432 HIV-positive under-five children on anti-retroviral therapy selected by simple random sampling from January 2010 to December 2019. A standardized data extraction tool was employed, which was adapted from anti-retroviral therapy entry and follow-up forms. The event of interest for this study is death, whereas the absence of experience of death is censored. Data were entered into Epi-Data version 3.1 and exported to STATA version 14. The Kaplan-Meier curve was used to estimate the survival probability. The Cox regression model was used to identify independent predictors of death. RESULTS: Among the 415 records included in the final analysis, 25 (6.02%) of the individuals were died. The incidence rate of death was found to be 2.87 per 1000 child-months (95%CI: 1.94-4.25). The cumulative survival probabilities of children after 6, 12, 24, and 36 months were 0.97, 0.95, 0.92, and 0.85 respectively. HIV-infected under-five children who lived in rural areas (AHR 3.32:-95% CI 1.17-9.39), with poor adherence to anti-retroviral therapy (AHR = 3.36; CI: 1.06, 10.69), without Isoniazide prophylaxis (AHR = 3.15; CI: 1.11, 8.94) and with anemia (AHR: 3.05, 95% CI: 1.16, 8.03) were at higher risk of death. CONCLUSION AND RECOMMENDATION: Death of HIV-infected under-five children on anti-retroviral therapy is high within the first one year after enrolment. Living in rural area, had poor adherence, lacked Isoniazide prophylaxis, and anemia were predictors of death. Therefore, clinicians shall emphasize for those specific risk factors of death and take action accordingly.

Time to death and its predictors among neonates who were admitted to the neonatal intensive care unit at tertiary hospital, Addis Ababa, Ethiopia: Retrospective follow up study.

Backgrounds: Neonatal death is the major problem in developing world. Burden and predictors of neonatal mortality vary across countries and even among regions of a country, so understanding the problem concerning these factors is essential to overcome the problem. Therefore, this study aimed to determine time to death and its predictors of neonatal mortality among neonates who were admitted to the neonatal intensive care unit of Tertiary Hospital, Addis Ababa, Ethiopia. Methods: A hospital-based retrospective cohort study was employed among 434 neonates admitted in Tertiary hospital, Addis Ababa, Ethiopia. A Kaplan Meier curve and a log-rank test were used to estimate the survival time and compare survival curves between variables. The cox proportional hazard model was also fitted to identify predictors. Results: A total of 434 neonates included in the study, 11.1% of which were died, and the incidence rate was 19.2 per 1000 live births. The time to death of neonates was 17 days. Independent predictors of neonatal mortality were incomplete maternal antenatal follow up[AHR: 3.7 (95% CI:1.86,7.60)], low(Appearance, Pulse, Grimily, Activity, and Respiration(APGAR)score[AHR:5.0 (95%CI:1.51-15.04)], perinatal asphyxia [AHR:5.2 (95%CI:1.92-14.30)], preterm 4.2 (95%CI: 1.32-8.83)]. Moreover, small for gestational age [AHR:4.8 (95%CI:2.33-9.72)], respiratory distress[AHR: 2.5 (95%CI: 1.24-5.09)], sepsis [AHR: 3.4 (95%CI: 1.71-4.01)], low birth weight[AHR: 7.3 (95%CI:2.69,1.91)], and tracheoesophageal fistula [AHR: 2.2 (95%CI: 1.13-4.32)]. Conclusion: The overall incidence rate was 19.2 deaths per 1,000 live births. Emphasis should be given to incomplete Antenatal care follow up, small for gestation, preterm, low birth weight, low 5th min APGAR score, neonatal sepsis, respiratory distress, perinatal asphyxia, and tracheoesophageal fistula.

Survival and predictors of asphyxia among neonates admitted in neonatal intensive care units of public hospitals of Addis Ababa, Ethiopia, 2021: a retrospective follow-up study.

BACKGROUND: Globally, perinatal asphyxia (PNA) is a significant cause of most neonatal deaths. Similarly, the burden of birth asphyxia in Ethiopia remains high (22.52%) and has been noted the second leading cause of neonatal mortality. Thus, researches on survival status and predictors of perinatal asphyxia are critical to tackle it. Therefore, the current study intended to determine the survival status and predictors of asphyxia among neonates admitted in Neonatal Intensive Care Units of public hospitals, Addis Ababa, Ethiopia. METHODS: Hospital-based retrospective follow-up study was conducted in four selected public hospitals of Addis Ababa from January 2016 to December 2020. Data were collected using a pretested structured questionnaire. Epi-data 4.6 and STATA Version 16 was used for data entry and analysis, respectively. Kaplan-Meier survival curve, log-rank test and Median time were computed. To find the predictors of time to recovery, a multivariable Cox proportional hazards regression model was fitted, and variables with a P-value less than 0.05 were considered statistically significant. Finally, the Schoenfeld residual test was used to check overall model fitness. RESULT: Four hundred eleven admitted asphyxiated babies were followed a total of 3062 neonate-days with a minimum of 1 h to a maximum of 28 days. The Overall incidence density rate of survival was 10 (95% CI: 0.08-0.11) per 100 neonate-days of observation with a median recovery time of 8 days (95% CI: 7.527-8.473). Low birth weight (Adjusted hazard ratio [AHR]: 0.67, 95% CI: 0.47-0.96), stage II hypoxic ischemic encephalopathy (HIE) (AHR: 0.70, 95% CI: 0.51-0.97), stage III HIE (AHR: 0.44, 95% CI: 0.27-0.71), seizure (AHR: 0.61, 95% CI: 0.38-0.97), thrombocytopenia (AHR: 0.44, 95% CI: 0.24-0.80) and calcium gluconate (AHR: 0.75, 95% CI: 0.58-0.99) were found to be independent predictors of time to recovery of asphyxiated neonates. CONCLUSION: In the current findings, the recovery time was prolonged compared to others finding. This implies early prevention, strict monitoring and taking appropriate measures timely is mandatory before babies transferred into highest stage of HIE and managing complications are recommended to hasten recovery time and increase survival of neonates.

Bromodomain containing 4 transcriptionally activated Deltex E3 ubiquitin ligase 2 contributes to glioma progression and predicts an unfavorable prognosis.

Background: Glioblastoma multiforme (GBM) is the most common type of glioma, and the most aggressive brain malignancy in adults. This study sought to identify novel survival-status related markers, and examine their function in glioma. Methods: The gene expression, survival heatmaps, and Kaplan-Meier survival plots of the genes were analyzed by using gene expression profiling interactive analysis (GEPIA) dataset, Linked Omics. The single-cell data analysis and tumor immune infiltration analysis was conducted by Tumor Immune Estimation Resource (TIMER) dataset. DBTRG and U251 cells with silenced Deltex E3 ubiquitin ligase 2 (DTX2) expression were constructed and used for Cell Counting Kit 8 (CCK-8), and wound healing assay in vitro. Chromatin immunoprecipitation sequencing (ChIP-seq) analysis was used to explore the histone activation marks and transcription factors DTX2 promoter. Dual-luciferase assays were carried out to detect the luciferase activities of bromodomain containing 4 (BRD4) binding to DTX2. Results: We first conducted a survival-status analysis to identify survival status-related genes in The Cancer Genome Atlas GBM and low-grade glioma data sets. A subsequent analysis identified 3 novel prognostic biomarkers; that is, DTX2, cytochrome P450 oxidoreductase, and Williams-Beuren syndrome chromosomal region 16 protein. In the validation Chinese Glioma Genome Atlas data sets, DTX2 showed the best performance, and was examined in a further analysis. Next, 3 short-hairpin ribonucleic acids were designed to silence DTX2 expression, and CCK-8 and wound-healing assays were applied to study the function of DTX2. We found that DTX2-silenced glioma cells exhibited a significant decrease in their growth and migration capabilities. Finally, the molecular basis for increased DTX2 in glioma was investigated via ChIP-Seq analysis and luciferase assays. The analysis revealed that DTX2 was transcriptionally activated by BRD4. Conclusions: In conclusion, BRD4 transcriptionally activates DTX2, contributes to glioma progression, predicts an unfavorable prognosis, and could provide new options for glioma prognosis prediction and treatment.

Lymphocyte percentage as a valuable predictor of prognosis in lung cancer.

Lymphocytes and neutrophils are involved in the immune response against cancer. This study aimed to investigate the relationship between lymphocyte percentage/neutrophil percentage and the clinical characteristics of lung cancer patients, and to explore whether they could act as valuable predictors to ameliorate lung cancer prognosis. A total of 1312 patients were eligible to be recruited. Lymphocyte percentage and neutrophil percentage were classified based on their reference ranges. Survival curves were determined using Kaplan-Meier method, and univariate and multivariate cox regression analyses were performed to identify the significant predictors. Decision curve analysis was used to evaluate the clinical benefit. The results of both training and validation cohorts indicated that lymphocyte percentage exhibited high correlation with clinical characteristics and metastasis of lung cancer patients. Both lymphocyte percentage and neutrophil percentage were closely associated with survival status (all p < 0.0001). Low lymphocyte percentage could act as an indicator of poor prognosis; it offered a higher clinical benefit when combined with the clinical characteristic model. Our findings suggested that pretreatment lymphocyte percentage served as a reliable predictor of lung cancer prognosis, and it was also an accurate response indicator in lung adenocarcinoma and advanced lung cancer. Measurement of lymphocyte percentage improved the clinical utility of patient characteristics in predicting mortality of lung cancer patients.

Survival status and predictors of mortality among HIV-positive children initiated antiretroviral therapy in Bahir Dar town public health facilities Amhara region, Ethiopia, 2020.

BACKGROUND: Although there is a presence of governmental and non-governmental organizations running to provide quality HIV care services to reduce HIV-related mortality, there is rapid disease progression and death among children in developing countries including Ethiopia. Thus, this study was aimed to assess the mortality predictors of children living with HIV at Bahir Dar town public health facilities. METHOD: A facility-based retrospective follow-up study was conducted among 588 children who were enrolled in the HIV care clinic from 1 September 2010 to 30 August 2019. Data were entered into the Epi-Data entry 3.1 and then exported to STATA version 14 for analysis. Multiple imputation models were employed to handle missing data using the multivariate imputation Chained Equations technique. The Kaplan-Meier survival curve and log-rank test were used to estimate and compare the survival time of categorical variables. RESULT: About 27 (4.6%) (95% confidence interval: 2.9-6.5) deaths were observed from the 30,062.3 person-months follow-up period, and the overall incidence density rate of 0.9 per 1000 child-months (95% confidence interval: 0.6-1.3). Advanced WHO clinical stage (adjusted hazard ratio = 3.18; 95% confidence interval: 1.07-9.43), hemoglobin level less than 8 g/dL (adjusted hazard ratio = 3.54; 95% confidence interval: 1.27-8.85), children having a weight for age of <-2z (adjusted hazard ratio = 2.81; 95% confidence interval: 1.19-6.6), children with poor adherence (adjusted hazard ratio = 3.91; 95% confidence interval: 1.41-10.8), and starting the treatment beyond 1 week of being eligible (adjusted hazard ratio = 3.22; 95% confidence interval: 1.21-8.53) were predictors of HIV-related mortality among children initiated antiretroviral therapy. CONCLUSION: The hazard of mortality was higher among HIV-infected children in the early period of initiation. Enhancing antiretroviral therapy drug adherence, monitoring Hgb level, and timely initiation of antiretroviral therapy reduce HIV-related mortality.
