Socio-demographic profiles, final admission diagnosis, duration of hospital stay and outcomes of hospitalization were variables recorded using a data abstraction checklist. Diseases were categorized using the World Health Organization’s International Classification of Diseases (ICD)-10 coding system. Data was analyzed using SPSS version 26.Results: Of the 2084 admissions over 1 year period, 767 (36.5%) had CVDs. The mean age of the study population was 53.4 ± 19.4 years with 55% females. Leading CVD admissions were stroke (35%), Venous thromboembolism (17%), rheumatic heart disease (RHD) (16.2%), ischemic heart disease (IHD) (11.3%) and cardiomyopathy (CMP) (7.4%). Heart Failure (HF) was found in 300 (39.1%) patients with structural heart disease. The structural cardiac lesions in those with HF were RHD (36%), CMP (19%), IHD (18%) and Cor pulmonale (9%). The in-hospital mortality of all CVD admissions was 13.2%. Of the total 101 CVD deaths most were because of stroke (n=37, 36.6%) followed by IHD (18.8%). Hypertension was the most frequent risk factor (28.8%).Conclusion: This study shows stroke to be the most common form of CVD and RHD to be the main reason for HF among hospital admissions in Northern Ethiopia, ACSH. Hypertension is the leading reported risk factor and hence the need to give high priority to hypertension and RHD control programs.Keywords: cardiovascular disease, admissions, outcomes, sub-Saharan Africa, Ethiopia

A significant number of TBLN patients who completed a full course anti-TB treatment regimen were reported to have enlarged lymph nodes and other TB-like clinical presentations. This could either be from a paradoxical reaction or microbiological relapse, possibly due to mono/multi-drug resistance.Objective: To investigate the rate of mono and multidrug resistance patterns of Mycobacterium tuberculosis as a cause of the observed treatment failures in clinically diagnosed and anti-TB treatment (newly or previously)-initiated LN patients.Methods: A cross-sectional study was conducted on 126 TBLN-suspected and previously treated patients between March and September 2022. Data were analyzed using SPSS (Version 26.0). Descriptive statistics were used to determine the frequency, percentage, sensitivity, specificity, and positive and negative predictive values. The level of agreement was determined using Cohen’s kappa and a Chi-square test was used to measure the association between risk factors and laboratory test outcomes. A P-value < 0.05 was considered statistically significant.Results: Mycobacterium tuberculosis was confirmed in 28.6% (N=36) of the 126 cases using BACTEC MGIT 960 culture detection method. Approximately, 13% (N=16) of the samples were collected from previously treated TBLN patients, of which 5/16 (31.3%) were multi-drug resistant, 7/16 were drug-sensitive and 4/16 were culture negative. To rule out other non-tuberculous agents, all samples were grown on blood and Mycosel agar plates, and no growth was detected.Conclusion: The emergence of drug resistant (DR) TB seems to not just be limited to pulmonary form but also to TBLN. In this study we observed a considerable number of microbiologically confirmed relapses among previously treated cases, possibly indicating the need for confirmation of drug resistance using rapid molecular methods or phenotypical methods during treatment follow up.Keywords: tubercular lymphadenitis, relapse, drug sensitivity testing, DST, FNA

Data on hospital admission in sub-Saharan Africa are scarce, particularly prospectively collected, and hence this study was done to close the gap in acquiring accurate diagnosis usually faced with retrospective data. We aimed to describe medical admission patterns, their outcomes and determinants at Ayder Comprehensive Specialized Hospital (ACSH) in Tigray, Ethiopia.Methods: Data were collected prospectively from November 1, 2017 to October 31, 2018 for all medical admissions. Sociodemographic profiles, final diagnosis, outcome of hospitalization, and complications were recorded using a data-abstraction checklist. Data were analyzed using SPSS 26.Results: There were 2084 medical admissions over 1 year. Median age was 45 years (IQR 31). A majority (1107, 53.1%) were male. The age-group 25– 34 years had the most admissions (19.0%). NCDs constituted 68.2% of admissions. According to the International Classification of Diseases, patients were admitted most frequently due to disease of the circulatory system (36.7%) followed by infectious or parasitic diseases (24.1%). Of NCDs, cardiovascular diseases contributed to 53.9%, followed by cancers (8.6%). Of CDs, HIV/AIDS contributed to 31.3%, followed by tuberculosis (22.8%). A total of 1375 (66%) were discharged improved, while 311 (14.9%) died. On multivariate analysis, the in-hospital mortality was significantly higher (18.7%) for CDs than NCDs (13.2%, AOR 1.8, 95% CI 1.4– 2.3; P< 0.001). Bed occupancy of ACSH medical wards and ICU was 54%.Conclusion: NCDs were leading causes of medical admissions in ACSH. The presence of CDs and the development of complications were associated with higher risk of death. Attention should be given by policy-makers to curb the higher morbidity from NCDs and mortality from CDs.Keywords: medical admissions, mortality, Ayder, Ethiopia

Temesgen Tsega Desta,1 Mulugeta Naizgi2 1Saint Paul Hospital Millennium Medical College, Addis Ababa, Ethiopia; 2Ayder Hospital, Mekelle University, Tigray, EthiopiaCorrespondence: Temesgen Tsega Desta Tel +251 911023103Email yafettemu@gmail.comBackground: Rheumatic fever continues to be a major public health problem in the developing world, being responsible for many morbidities and mortalities. Were it not for its serious effects on the cardiovascular system, and to some extent on the central nervous system, the disease might not have significant consequences. The central nervous system involvement is explained with Sydenham chorea in which case the patient manifests with purposeless and choreiform movements aggravated by stress. Apart from this movement disorder the patient will also demonstrate emotional liability and motor manifestations. It is seen more commonly in children and young adolescent girls. It usually manifests as an isolated phenomenon called pure chorea, without evidence of active rheumatic fever; the other rare form of which is a type of acute rheumatic fever.Clinical Description: This case report is about a nine-year-old female child presenting with two weeks of complaint of abnormal purposeless, non-rhythmic movement of extremities and the face, with failure to communicate. At presentation, she had non-pruritic skin lesions that had appeared a day prior to admission. The skin lesions were circular, red in color, and painless, involving the abdomen, and lower chest anteriorly, and extending to all extremities and the back. Two months previously she had a history of sore throat and treatment with unspecified P.O. medication. Antistreptolysin O (ASO) antibody was 430 Todd units/mL and the erythrocyte sedimentation rate was 58 mm/h. Echocardiography study revealed carditis (no evidence of chronicity) with moderate to severe MR, mild TR, no pulmonary hypertension, good biventricular function, and no pericardial effusion.Conclusion: In this case report, we would like to show the central nervous system manifestation of rheumatic fever called Sydenham chorea seen together with erythema marginatum and other features of rheumatic fever.Keywords: Sydenham chorea, erythema marginatum, rheumatic recurrence, antistreptolysin O antibody

The performance of six primary health workers was evaluated after following a 9-day training course on integrated management of childhood illness (IMCI). The participants were selected from three primary health centres in the Gondar District, Ethiopia, and the course was focused on assessment, classification, and treatment of sick children (aged 2 months to 5 years) and on counselling of their mothers. Immediately following this training, a 3-week study was conducted in the primary health centres to determine how well these workers performed in assessing, classifying and treating the children and in counselling the mothers. A total of 449 sick children who presented at the three primary health centres during the study period were evaluated. Most of the complaints (87%) volunteered by the mothers (fever, cough, diarrhoea, and ear problems) were covered by the IMCI charts. The assessment of commonly seen signs (tachypnoea or ear pain) or easily identifiable signs (slow return after skin pinch, wasting, or pedal oedema) was good, with sensitivities of 67-91%, whereas the assessment of uncommonly seen signs (dry mouth, corneal clouding) or less easily quantifiable signs (eyelid pallor, absence of tears) had a fair or poor sensitivity of 20-45%. The classification of pneumonia, diarrhoea with signs of dehydration, and malnutrition showed sensitivities of 88%, 76%, and 85% and specificities of 87%, 98%, and 96%, respectively. However, the classification of febrile illnesses had a sensitivity of only 39% due to problems in using the draft algorithm in areas with a mixture of high, low, and no malaria risk, and due to confusion between axillary and rectal temperature thresholds. Of 39 children classified as having severe disease, 9 were misclassified, mostly by one nurse. Treatment of patients improved over the three weeks of observation, their completeness increasing from 69% to 88%. Health workers usually communicated appropriate advice to the mother. They learned to use checking questions but failed to adequately solve problems in the majority of cases. The mother&apos;s counselling card, which summarized recommendations on feeding and home fluids, and advice on when to return, was widely used to aid communication. The time taken to perform the complete management of children did not change significantly (20 to 19 minutes) during the study. Lessons from our findings have been incorporated into an improved version of the IMCI charts., Introduction This article describes the first test of the draft training materials for integrated management of childhood illness (IMCI) by first-level primary health workers. Previous studies on the IMCI algorithm [...]

Background: Porphyromonas gingivalis is a Gram-negative bacterium that is an important etiologic agent of human adult periodontitis. The goal of the study was to test the hypothesis that two isoforms of P. gingivalis lipopolysaccharide (PgLPS), PgLPS(1435)(/1449) and PgLPS(1690), exhibit differences in their capacity to stimulate systemic versus local responses compared to Escherichia coli lipopolysaccharide (LPS).Methods: LPS was inoculated into the scalp of mice, and the response was measured locally at the site of inoculation and systemically in the heart/aorta. Vascular cell adhesion molecule (VCAM)-1 was assessed at the protein level by enzyme-linked immunosorbent assay, and VCAM-1, E-selectin, and intercellular adhesion molecule (ICAM)-1 were assessed at the RNA level of the RNase protection assay. Serum tumor necrosis factor-alpha (TNF-alpha) levels were also measured.Results: E. coli LPS and both isoforms of P. gingivalis LPS were relatively potent in stimulating the expression of inflammatory markers, with E. coli LPS being more potent. In contrast, when the systemic response was measured in the heart/aorta, E. coli LPS, but not P. gingivalis LPS, significantly induced inflammatory markers. At moderate to low doses (1 and 10 microg per injection), serum TNF-alpha levels were minimally induced by P. gingivalis LPS compared to E. coli LPS.Conclusions: Both forms of P. gingivalis LPS stimulated an inflammatory response when injected into connective tissue but were minimally stimulatory when a systemic response was measured. In contrast, E. coli LPS was a potent stimulus at the systemic and local levels. [ABSTRACT FROM AUTHOR]

This paper outlines a methodology for the reduction of a complex computational fluid dynamics (CFD) model using data-based mechanistic (DBM) modelling technique. For this study a full scale, adiabatic walled ventilated installation was used. Primarily, a CFD model that is three dimensional, transient and turbulent was proposed and solved by a commercial package CFX 4.3 in order to obtain informative data that will be used to build a DBM model. At the inlet a step rise in temperature was applied and the ventilation rate is kept steady. Turbulence is modelled by the widely used standard k–ε model. Temperature responses at 36 monitoring positions inside the installation were extracted out of the simulation. In the second stage of the work, for the same ventilation system, a DBM model was formulated from an energy balance equation. The simplified refined instrumental variable (SRIV) algorithm is employed as model parameter identification tool. The obtained highly accurate model parameters for all monitoring positions demonstrate the possibility of reducing complex CFD models using identification technique. [Copyright &y& Elsevier]

Introduction: Tuberculous lymphadenitis (TBLN) is an infection of the lymph node caused by Mycobacterium tuberculosis. Histological diagnoses of presumptive patients are often accompanied by cytomorphological features. However, the sensitivities of these features are often precluded by the variable degrees of narrative similarities compared to other diagnostic modalities., Objective: The aim of this study was to investigate and compare the cytomorphological and clinical features of presumptive TBLN patients with bacteriological detection methods., Methods: A similar cohort of TBLN patients from our previous study who were enrolled prospectively from the ALERT Specialized Hospital, Addis Ababa, Ethiopia, was considered for this analysis. SPSS version 26 was used for data analysis. Descriptive analysis was conducted to characterize the study population using the independent variable and presented with frequency tables. The chi-square test was used to measure the association. A P-value of < 0.05 was considered statistically significant., Results: Using FNAC, 60/126 (47.6%) of the participants were reported to have features consistent with TB. Of the total FNAC-positive cases, many (30/60 and 27/60) showed pattern B (caseous necrosis only) and pattern C (epithelioid granuloma with caseous necrosis), respectively. Strong concordance was observed in Pattern A (abundant caseous necrosis with few epithelioid macrophages) followed by patterns B and C with GeneXpert and MGIT culture (P value < 0.001). Night sweats and alcohol intake were shown to correlate with positive cases as reported by FNAC (P value = 0.008 respectively), GeneXpert (P value = 0.02 & 0.001), and culture methods (P-value = < 0.001 & 0.002)., Conclusion: Cytomorphological features, particularly patterns A, B, and C, could be considered in the diagnosis of TBLN given their comparable outcomes with bacteriological detection methods. On another note, we recommend that due care and attention be given when treating TBLN patients based solely on clinical presentation, as these diagnostics may be prone to false results, leading to inappropriate administration of anti-TB drugs and other consequences., (© 2024.

Background: With a neonatal mortality rate of 33 per 1,000 live births in 2019, Ethiopia is striving to attain the Sustainable Development Goal target of 12 deaths per 1,000 live births by 2030. A better understanding of the major causes of neonatal mortality is needed to effectively design and implement interventions to achieve this goal. Minimally Invasive Tissue Sampling (MITS), an alternative to conventional autopsy, requires fewer resources and through task-shifting of sample collection from pathologists to nurses, has the potential to support the expansion of pathology-based post-mortem examination and improve mortality data. This paper evaluates the accuracy and adequacy of MITS performed by nurses at a tertiary and general hospital and in the home of the deceased., Methods: Nurses in a tertiary and general hospital in Ethiopia were trained in MITS sample collection on neonatal deaths and stillbirths using standardized protocols. MITS sample collection was performed by both pathologists and nurses in the tertiary hospital and by nurses in the general hospital and home-setting. Agreement in the performance of MITS between pathologists and nurses was calculated for samples collected at the tertiary hospital. Samples collected by nurses in the general hospital and home-setting were evaluated for technical adequacy using preestablished criteria., Results: One hundred thirty-nine MITS were done: 125 in hospitals and 14 inside homes. There was a perfect or almost perfect agreement between the pathologists and the nurses in the tertiary hospital using Gwet's agreement interpretation criteria. The adequacy of MITS samples collected by nurses in the general hospital was more than 72% when compared to the preset criteria. The adequacy of the MITS sampling yield ranged from 87% to 91% on liveborn neonatal deaths and 76% for the liver, right and left lungs and 55% for brain tissues in stillbirths., Conclusions: This study demonstrated that task-shifting MITS sample collection to nurses can be achieved with comparable accuracy and adequacy as pathologists. Our study showed that with standardized training and supportive supervision MITS sample collection can be conducted by nurses in a tertiary, general hospital and, at the home of the deceased. Future studies should validate and expand on this work by evaluating task-shifting of MITS sample collection to nurses within community settings and with larger sample sizes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Muhe, Paganelli, Ayele, Desta, Mekasha, Demtse, Awoke, Elfu, Gebremariam, Tamrat, Jiffar, Zenabu, Sori, Parlberg, Worku and Nigussie.)

Purpose: Different biological characteristics, therapeutic responses, and disease-specific outcomes are associated with different molecular subtypes of breast cancer (BC). Although there have been different studies on BC in the Ethiopian capital city of Addis Ababa, there have been few studies in other parts of the nation, and none have evaluated biological characteristics in other locations in the context of the extensive ethnic and genetic diversity found in Ethiopia. This study was carried out to evaluate the distribution of immunohistochemistry (IHC) subtypes of BCs throughout four Ethiopian regions., Methods: A total of 227 formalin-fixed paraffin-embedded (FFPE) tissue blocks were collected from tertiary hospitals in four Ethiopian regions between 2015 and 2021. The IHC staining was performed for subtyping, ER, PR, HER2, and Ki-67 proliferation markers., Results: The mean age at diagnosis was 43.9 years. The percentage of ER and PR-negative tumors were 48.3% and 53.2%, respectively. The IHC subtypes showed the following distribution: 33.1% triple-negative breast cancer (TNBC), 27.6% luminal B, 25.2% luminal A, and 14.1% HER2 enriched. In multiple logistic regression analysis, grade III and HER2 positivity were associated with larger tumor size, and also originating from Jimma compared to Mekele., Conclusion: Patients with ER-negative, PR-negative, and TNBC were found in 48.3%, 53.2%, and 33.1% of cases, respectively, showing that half the patients could potentially benefit from endocrine treatment. A considerably high prevalence of TNBC was reported in our study, demanding additional research that includes genetic predisposition factors. Additionally, aggressive tumors were found in a high percentage of younger age groups, which must be considered when planning personalized treatment strategies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Belachew, Desta, Gebremariam, Deneke, Ashenafi, Yeshi, Fenta, Alem, Alemu, Abafogi, Desta, Chanyalew, Beshah, Taylor, Bauer, Tsehay, Girma, Melka, Tessema, Kantelhardt and Howe.)

Background: Tibial shaft fractures are the most common long bone fractures requiring treatment. High-energy trauma often causes tibia bone injuries, causing severe complications and long-term disability due to inadequate soft tissue coverage. Tibial shaft fractures can be treated using casts, external fixators, plating, or intramedullary nails. Intramural nailing leads to faster union and reduced complications like malunion and shortening. However, patients often report subjective and objective difficulties after Surgical Instrument generation network (SIGN) nail fixation, affecting knee range of motion, quality of life, and sport activities. Tibial nails and plates are associated with increased knee pain, which negatively affects functional outcomes. No study has been conducted in a poor resource setting like Ethiopia. This study aims to assess functional outcomes of the knee and associated factors after intramedullary nailing of Tibial Diaphysial Fractures at AaBET hospital in Ethiopia., Methods: A retrospective health facility based cross-sectional study was conducted on functional outcomes of the knee and associated factors after intramedullary nailing of tibial diaphysial fractures done at AaBET hospital. A medical record review form and a structured questionnaire from patient chart and SIGN nail database collected data. The study was conducted on 151 patients registered on the SIGN nail database using a simple random sampling. Knee injury and Osteoarthritis Outcome Score (KOOS) was used to assess the knee functional outcome. Descriptive statistics such as frequency and percentage were used to summarize the results and binary logistic regression was used to describe the association between variables. P value < 0.05 was considered statistically significant association., Results: The study constituted 151 patients with tibial shaft fractures; 113(74.8%) males and 38(25.2%) females with a mean age of 31.4 years, with a standard deviation of [10.5]. The prevalence of patients with good knee functional outcomes was 87(57.6%), while 64(42.4%) patients had poor knee functional outcomes. Associated factors identified include sex, age, soft tissue status, postoperative infection postoperative physiotherapy and comminuted fracture pattern., Conclusion and Recommendation: This study determined the magnitude of knee functional outcomes revealed that more than half (57.6% ) of patients had good knee functional outcomes with identified factors increseaes odds of poor knee functional outcomes were sex, age, soft tissue injuries, post operative infection, postoperative physiotherapy and comminuted fracture patterns respectively. Therefore, Policymakers and health planners should closely monitor postoperative physiotherapy treatment courses among tibial shaft fractures treated with intramedullary nailing to increases good knee functional outcomes., (© 2023.

Objectives: The intramedullary nailing of long bone fractures is a major challenge for orthopedic surgeons, with increased risk of infection in third-world countries. Research gaps remain in Ethiopia, determining the magnitude of the problem. This study aimed to determine the prevalence and associated factors of infection after intramedullary nailing of long bone fractures in Ethiopia., Methods: This was a descriptive, cross-sectional, retrospective design study with a total census of 227 cases of long bone fractures treated with intramedullary Surgical Implant Generation Network nails at Addis Ababa Burn Emergency and Trauma Hospital from August 2015 to April 2017. Data were collected from 227 patients and descriptive analyses were done to summarize the study variables. Binary and multivariable logistic regression analyses were performed at a p value of 0.05 with a 95% confidence interval and adjusted odds ratio., Results: The mean age of patients was 32.9 years, with a male-to-female ratio of 3.5:1. Only 22 (9.3%) of the 227 patients with long bone fractures treated with intramedullary nails developed a surgical site infection, and 8 (3.4%) were developed deep (implant) infections requiring debridement. Road traffic injuries were the leading cause of trauma (60.9%), followed by falls from a height (22.7%). Debridement was done within 24 h for 52 (61.9%) and within 72 h for 69 (82.1%) patients with open fractures. Only 19 (22.4%) and 55 (64.7%) patients with open fractures and tibial long bone fractures received antibiotics within 3 h. Open fractures and tibial fractures had higher percentages of infection, 18.6% and 12.1%, respectively. Previous use of an external fixator (44.4%) and prolonged surgery (12.5%) were associated with higher proportions of infection., Conclusion: This study found that the prevalence of infections after intramedullary nailing of long bone fractures in Ethiopia was 44.4% after external fixation, compared to 6.4% after intramedullary nail was inserted directly. Proper control measures are needed to reduce morbidity and complications related to long fracture treatment, such as open fractures, tibial fractures, the use of an external fixator, delayed debridement and skin closure, and prolonged surgery developed surgical site infection rate., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Background: In Ethiopia, little is known about postoperative pain trajectories and possible predictive factors associated with them in patients undergoing surgery following traumatic fractures., Methods: This multi-center prospective observational cohort study included surgical candidates for traumatic fractures (n = 218). Worst pain intensity was measured with an 11-point numeric rating scale on the first 4 postoperative days and day of hospital discharge. Growth mixture modeling was used to identify subgroups of patients based on their pain trajectories, and logistic regression models to quantify associations between pain trajectories and demographic, clinical, psychological, and life style factors., Results: Two postoperative pain trajectory subgroups were identified: rapid pain relief (48% of included individuals) and consistently high pain (52% of included individuals). Sub-analysis stratified by cause of injury demonstrated that higher preoperative pain was an independent risk factor for consistently high postoperative pain regardless of the patient's injury type: traffic accident (OR = 1.48, 95% CI 1.23-1.79), machine/tool injury or conflict (OR = 1.58, 95% CI 1.11-2.26), or fall (OR = 1.47, 95% CI 1.08-1.99). Moreover, longer surgical time was a risk factor for consistently high postoperative pain among patients who had a fall-related injury (OR = 1.02, 95% CI 1.00-1.03). In contrast, among patients with a traffic-related injury, receiving a nerve block was a protective factor (OR = 0.19, 95% CI 0.04-0.87) compared with general anesthesia., Conclusion: Higher preoperative pain and longer surgical time were associated with a consistently high acute postoperative pain trajectory. Clinicians may use these potentially modifiable factors to identify patients at risk for consistently high pain during the early postoperative period., (© 2023. The Author(s).)

Objectives: To determine the outcome of tibial fractures treated with the SIGN FIN nail., Study Design: Retrospective case series study., Study Setting: Trauma center., Methods and Materials: We included 14 patients aged 18-51 years with 16 tibial fractures in this study. Patients were followed clinically and radiographically, and the minimum time followed was 6 months. Johner and Wruhs criteria with modification were used to assess the outcome., Result: There were 11 male (78.6%) and three female (21.4%) patients. The mean age was 32.44 ± 8.98 (range 18-51) years. The right-sided tibia was injured in six as compared with the left side in four, and four patients had bilateral injuries. Eight (50%) fractures were closed fractures, whereas the rest eight (50%) were open types of fractures. Among the latter, half (n = 4; 50%) fractures were Gustilo type II fractures, while three (37.5%) fractures were Gustilo type III fractures, and one (12.5%) patient had a Gustilo type I fracture. All patients had radiologic union. There were no infections or secondary surgery for any reason. Excellent, good, and fair results were achieved in 62.5%, 25%, and 12.5%, respectively. All patients were able to return to their preinjury activity except two patients., Conclusion: SIGN FIN nail is an option for treating tibial shaft fractures with good outcomes and few complications in selected fractures., Level of Evidence: Level IV., Competing Interests: The authors report no conflict of interest., (Copyright © 2023 The Authors.

Objective: This study aimed to assess the incidence and associated factors of acute postoperative pain after cesarean section within the first 24 h of postoperative period., Methods: An institutional-based prospective observational study was conducted on parturients who had undergone cesarean section in Gandhi Memorial Hospital from 1 December 2019 to 28 February 2020. A numerical rating scale was used to evaluate the incidence of acute postoperative pain. Patients having a pain score of >4 were considered having moderate-to-severe pain on numerical rating scale. Data were analyzed using SPSS version 20. Bivariable and multivariable logistic regression were used to assess the association of variables. A p value of less than 0.05 was taken as significant association with dependent variables., Result: In total, 290 parturients participated in the study with a response rate of 98%. Moderate-to-severe acute postoperative pain after cesarean section was 76.2% (95% confidence interval: 71%, 81%) in the first 24 h postoperatively. On multivariable analysis, previous cesarean section history (adjusted odds ratio: 2.80, 95% confidence interval: 1.40, 5.55; p  = 0.003), preoperative anxiety (adjusted odds ratio: 2.70, 95% confidence interval: 1.45, 5.05; p  = 0.003), transverse incision type (adjusted odds ratio: 3.35, 95% confidence interval: 1.67, 6.72; p  = 0.002), and incision length (adjusted odds ratio: 2.46, 95% confidence interval: 1.24, 4.85; p  = 0.009) were identified as risk factors for postoperative moderate-to-severe acute pain., Conclusion: The incidence of moderate-to-severe postoperative pain was high in the first 24-h postoperative period; this indicates that pain management after cesarean section was treated inadequately. History of previous cesarean section, preoperative anxiety, transverse incision, and incision length >10 cm were the factors of postoperative acute pain after cesarean section.

Background & Aims: EDP-305 is an oral farnesoid X receptor (FXR) agonist under development for the treatment of non-alcoholic steatohepatitis (NASH). Herein, we aimed to assess the efficacy, safety and tolerability of EDP-305 in patients with fibrotic NASH., Methods: In this double-blind phase II study, patients with fibrotic NASH (without cirrhosis), diagnosed by historical biopsy or phenotypically, were randomized to EDP-305 1 mg, EDP-305 2.5 mg, or placebo, for 12 weeks. The primary endpoint was mean change in alanine aminotransferase (ALT) from baseline to Week 12, and the key secondary endpoint was mean change in liver fat content from baseline to Week 12., Results: Between January 2018 and July 2019, 134 patients were randomized and 132 were evaluated. At Week 12, the least squares mean reductions from baseline in ALT for patients receiving 2.5 mg EDP-305 and 1 mg EDP-305 were -27.9 U/L (95% CI 0.03 to 24.9; p = 0.049) and -21.7 U/L (-5.8 to 18.3: p = 0.304), respectively, compared to -15.4 U/L for those receiving placebo. Absolute liver fat reduction was -7.1% (2.0-7.5; p = 0.0009) with 2.5 mg EDP-305, -3.3% with EDP-305 1 mg, and -2.4% with placebo. The most common (≥5%) adverse events were pruritus, nausea, vomiting, diarrhea, headache, and dizziness. Pruritus occurred in 50.9%, 9.1%, and 4.2% of patients in the 2.5 mg, 1 mg, and placebo groups, respectively, and led to study drug discontinuation in 20.8% of patients in the 2.5 mg group and 1.8% in the 1 mg group., Conclusions: EDP-305 reduced ALT levels and liver fat content, providing support for a longer-term trial assessing histological endpoints in patients with NASH. CLINICALTRIALS., Gov Number: NCT03421431 LAY SUMMARY: Non-alcoholic fatty liver disease is a chronic hepatic disease that can progress to non-alcoholic steatohepatitis (NASH), which is associated with an increased risk of cirrhosis and liver cancer.
