Proportion and risk factors of low birth weight among neonates delivered at Omdurman Maternity Hospital, Sudan.

Low birth weight (LBW) is a major predictor of child mortality and morbidity. The objectives of this study are to determine the proportion and risk factors of LBW. A matched case-control study was conducted at Omdurman Maternity Hospital, Sudan. The study population consisted of all babies delivered in August 2016 excluding stillbirths, multiple births, and babies with insufficient data. All LBW neonates were selected using total coverage sampling as cases and matched on babies' gender with randomly selected normal birth weights as controls. The sample size was 350 babies; 175 test cases and 175 control cases. Data were collected from hospital records and six risk factors were tested: mother age, parity, gravidity, mode of delivery, hypertensive disorders, and diabetes mellitus. The proportion of LBW was 10.8% of the total number of delivered neonates which is 2,938. The bivariate analysis identified that younger mother age (p = 0.03) and hypertension (p = 0.02) were significantly associated with LBW while other factors were found statistically insignificant. Multivariable conditional logistic regression revealed that hypertensive disorders in pregnancy increase the risk for LBW almost three times [Adjusted OR = 2.98 (95% CI: 1.23-7.22), p = 0.02]. We found that hypertension is an independent risk factor for LBW. The proportion of LBWcan be reduced if hypertension is controlled by providing simple measures like proper antenatal care and health education for pregnant women.

Barriers Preventing Medical Trainees from Active Participation in Research Activities.

Background: Research has increasingly become important to career progression and a compulsory component in most medical programs. While medical trainees are consistently urged to undertake research endeavors, they frequently encounter obstacles at both personal and organizational levels that impede the pursuit of high-quality research. This study aims to identify the barriers and recommend successful interventions to increase research productivity amongst medical trainees. Methods: A descriptive cross-sectional survey was carried out among interns, residents, and fellows within a single hospital located in the emirate of Abu Dhabi, UAE. The survey included inquiries regarding perceived obstacles hindering engagement in research activities, factors driving motivation for research involvement, and the assessment of how research participation relates to their job in terms of relevance. Results: Fifty-seven medical trainees participated in the survey, reflecting a response rate of 53%. The survey highlighted common obstacles, notably including time constraints, insufficient statistical and methodology training, the weight of other educational commitments, as well as inadequate incentives and rewards. While a majority of participants expressed interest in engaging in research activities, the consensus was that more incentives and increased funding opportunities would significantly encourage their involvement. Conclusion: Implementing successful interventions such as allocating dedicated time for research, facilitating access to research mentors, and organizing training sessions have the potential to be effective strategies in fostering a thriving research culture and subsequently elevating research productivity of medical trainees.

Serological Responses to Trachoma Antigens prior to the Start of Mass Drug Administration: Results from Population-Based Baseline Surveys, North Darfur, Sudan.

After years of programmatic inaccessibility, in 2019-2020 the Sudan Federal Ministry of Health Trachoma Control Program conducted population-based trachoma surveys in three localities (districts) in North Darfur state, Sudan. These baseline surveys were to determine the prevalence of trachomatous inflammation-follicular (TF) among children aged 1-9 years and to further use serological markers to understand the historical trachoma burden within this mass drug administration (MDA)-naive area. Trained and certified graders collected trachoma clinical data, and trained nurses collected dried blood spot (DBS) samples. The DBSs were assayed on a multiplex bead array for antibody responses to the Chlamydia trachomatis antigens Pgp3 and CT694. Across the three localities, 3,613 individuals aged 1-9 years and 3,542 individuals aged ≥15 years were examined for clinical signs, and 8,322 DBSs were collected. The prevalence of TF among children aged 1-9 years was endemic (≥5%) in two localities (El Seraif, 15.6%, and Saraf Omrah, 11.0%) and below the TF elimination threshold (<5%) in the third (Kotom, 1.4%). The Pgp3 seroprevalence among children aged 1-9 years was 34.1% in El Seraif, 35.0% in Saraf Omrah, and 11.0% in Kotom. Locality prevalence results were similar for Pgp3 and CT694. Seroprevalence increased with age in all three localities. Serological data collected within these surveys demonstrate that all three localities have had a long history of exposure to Chlamydia trachomatis and that two of the three localities require MDA to reach elimination as a public health problem threshold.

Evaluation of point-of-care ultrasound training among healthcare providers: a pilot study.

BACKGROUND: The use of Point-of-Care Ultrasound (POCUS) has become prevalent across a variety of clinical settings. Many healthcare professionals have started getting hands-on training. To evaluate the effectiveness of such training programs, this study aimed to assess a 4 day POCUS training course on healthcare providers' skills and knowledge acquisition. A secondary objective of this study is to gain valuable insights into the degree of perception, attitude, interest levels and perceived barriers of medical providers performing POCUS. METHODS: This is a prospective cohort study performed on healthcare providers in an integrated healthcare facility in Abu Dhabi undergoing the POCUS training course in February 2022. Course participants took a pre-course survey to evaluate their baseline knowledge, skills, confidence, perception, and interest in POCUS. The same survey was repeated immediately post-course. In total, seven healthcare professionals responded to the survey with a response rate of 53.8%. All data and information gathered were used to understand the effectiveness of POCUS training and gain insights into the degree of perception, interest and preparedness of POCUS among healthcare professionals in practice. RESULTS: Our results demonstrated that the brief POCUS course was effective in improving POCUS skills, knowledge and confidence amongst in-practice healthcare providers from varying medical specialties. The median skill score increased from 25% pre-course to 50% post-course. There is a notable increase in all skills scores after the POCUS training course with the greatest change in scores seen for adjusting 'gain and depth of image (54.84%), assessing VeXUS score (52.38%) and evaluating lung congestion (50%). The study also provided valuable insights into the perception, attitude, interest and potential barriers of POCUS implementation. Although significant barriers to POCUS are present including the lack of POCUS curriculum, what is challenging is lack of expertise and skills to perform POCUS. Therefore, medical providers must acquire prespecified skills to fully utilize POCUS effectively. CONCLUSION: The study confirmed the effectiveness of short POCUS training in improving the skills, knowledge and confidence of medical providers in practice. Healthcare professionals can master POCUS skills and techniques and gain confidence through brief training courses.

Leveraging artificial intelligence and decision support systems in hospital-acquired pressure injuries prediction: A comprehensive review.

BACKGROUND: Hospital-acquired pressure injuries (HAPIs) constitute a significant challenge harming thousands of people worldwide yearly. While various tools and methods are used to identify pressure injuries, artificial intelligence (AI) and decision support systems (DSS) can help to reduce HAPIs risks by proactively identifying patients at risk and preventing them before harming patients. OBJECTIVE: This paper comprehensively reviews AI and DSS applications for HAPIs prediction using Electronic Health Records (EHR), including a systematic literature review and bibliometric analysis. METHODS: A systematic literature review was conducted through PRISMA and bibliometric analysis. In February 2023, the search was performed using four electronic databases: SCOPIS, PubMed, EBSCO, and PMCID. Articles on using AI and DSS in the management of PIs were included. RESULTS: The search approach yielded 319 articles, 39 of which have been included and classified into 27 AI-related and 12 DSS-related categories. The years of publication varied from 2006 to 2023, with 40% of the studies taking place in the US. Most studies focused on using AI algorithms or DSS for HAPIs prediction in inpatient units using various types of data such as electronic health records, PI assessment scales, and expert knowledge-based and environmental data to identify the risk factors associated with HAPIs development. CONCLUSIONS: There is insufficient evidence in the existing literature concerning the real impact of AI or DSS on making decisions for HAPIs treatment or prevention. Most studies reviewed are solely hypothetical and retrospective prediction models, with no actual application in healthcare settings. The accuracy rates, prediction results, and intervention procedures suggested based on the prediction, on the other hand, should inspire researchers to combine both approaches with larger-scale data to bring a new venue for HAPIs prevention and to investigate and adopt the suggested solutions to the existing gaps in AI and DSS prediction methods.

Idiopathic Myointimal Hyperplasia of Mesenteric Veins (IMHMV) with two spontaneous bowel perforations: A case report and literature review.

INTRODUCTION AND IMPORTANCE: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a poorly understood disorder which poses a diagnostic challenge to clinicians and pathologists. Here we have described the case of a male patient with IMHMV along with a presumed history of ulcerative colitis for 1 year. CASE PRESENTATION: A 55-year-old male presented to the OPD with history of chronic abdominal pain. Clinical and radiological examination coupled with endoscopic findings resulted in the patient being wrongly diagnosed to be a case of ulcerative colitis and was managed accordingly. Throughout his multiple hospital visits following treatment for ulcerative colitis, the patient was persistently symptomatic. He presented with 10 days history of increasing abdominal pain and constipation following which he developed spontaneous colonic perforation for which he underwent exploratory laparotomy left colectomy and Hartman's procedure. The final pathology of the resected colon found to be consistent of Idiopathic myointimal hyperplasia of the mesenteric veins and ischemic bowel changes. CLINICAL DISCUSSION: The absence of clear-cut endoscopic biopsy findings of ulcerative colitis made radiological picture to be the mainstay for diagnosis, which was inaccurate and exposed the patient to unnecessary treatment with immuno-modulators thus resulting in poor response to treatment. As the disease progressed, further narrowing of the vessels made the clinical picture to look closer to ischemic bowel pathology as the patient developed a top surgical emergency (i.e. bowel perforation). Such pathological finding (IMHMV) can only be diagnosed in a fully prepared tissue histology, but rather be considered when no other consistent alternative diagnosis was found. CONCLUSION: The treating physicians must definitely consider the possibility of idiopathic myointimal hyperplasia of mesenteric veins when similar manifestations are encountered in biopsy specimens of old cases with suspected inflammatory bowel disease or non-occlusive ischemia of the distal colorectum.

Chemical profile, antiproliferative, antioxidant, and enzyme inhibition activities and docking studies of Cymbopogon schoenanthus (L.) Spreng. and Cymbopogon nervatus (Hochst.) Chiov. from Sudan.

Essential oils from the inflorescence of Cymbopogon schoenanthus and C. nervatus growing in Northern Sudan were examined for their chemical composition, antiproliferative activity against human breast carcinoma and human colon adenocarcinoma cell lines, antioxidant activity (phosphomolybdenum, antiradical, reducing power, and ferrous chelating), and enzyme inhibition activity against acetylcholinesterase butyrylcholinesterase, tyrosinase, α-glucosidase, and α-amylase. In silico study on the inhibition of tyrosinase and α-amylase was also performed. Piperitone (59.1%) and isomers of para-menthadienols (35.3%) were the main compounds in C. schoenanthus and C. nervatus oils, respectively. Oil from C. nervatus possessed higher antioxidant activity than that from C. schoenanthus except for its metal chelating ability. Both oils showed high antiproliferative activity. In silico study showed that trans-p-mentha-2,8-dien-1-ol and piperitone (both isomers) revealed the best docking scores for α-amylase and tyrosinase, respectively. In conclusion, oils from these two Cymbopogon species could be new natural agents with functional properties for food, cosmetics, and pharmaceutical industries. PRACTICAL APPLICATIONS: Recently, there is a growing tendency to replace synthetic oils by natural ones in the cosmetic, food, and pharmaceutical products. In this context, we investigated the chemical characterization and biological activities of two Cymbopogon species essential oils (C. schoenanthus (L.) Spreng. and C. nervatus). Antioxidant capacity, enzyme inhibition, and antiproliferative effects were tested for biological activities. Chemical characterization was identified by GC-MS. Based on our findings, the Cymbopogon species may be utilized as sources of natural bioactive agents in food industries.

Near-Infrared Spectroscopy Analysis of Coronary Chronic Total Occlusions.

OBJECTIVE: To examine the presence and localization of lipid-core plaque (LCP) in coronary vessels with chronic total occlusions (CTOs) using near-infrared spectroscopy (NIRS). METHODS: NIRS imaging was performed after guidewire crossing of the occlusion in 15 patients with CTOs. LCP was defined as ≥2 adjacent 2 mm yellow blocks on the block chemogram. We also measured the maximum lipid-core burden index (LCBI) in a 4 mm length of artery (maxLCBI4mm). Large LCP was defined as maxLCBI4mm ≥500. RESULTS: Median patient age was 64 years (interquartile range [IQR], 61-67 years) and all patients were men with high prevalence of diabetes mellitus (64%) and prior coronary artery bypass graft surgery (27%). The CTO target vessel was the right coronary artery (46%), left anterior descending artery (27%), or circumflex artery (27%). Median occlusion length was 35 mm (IQR, 30-50 mm). LCP was present in 11 of 15 CTO vessels (73%) and a large LCP in 4 of 15 CTO vessels (27%). LCP was located at the proximal cap in 6 CTOs (55%), the CTO body in 6 CTOs (55%), and the distal cap in 2 CTOs (18%). The median overall LCBI and maxLCBI4mm were 145 (IQR, 79-243) and 415 (IQR, 267-505), respectively. All patients underwent successful stenting without any complications. The 12-month incidence of in-stent restenosis and target-lesion revascularization was 25%, and all patients who developed restenosis had an LCP at baseline. CONCLUSIONS: LCPs are commonly encountered in coronary CTO vessels, suggesting an active intraplaque atherosclerotic process. The impact of LCP on postintervention outcomes requires further study.

Saphenous vein graft interventions.

OPINION STATEMENT: Saphenous vein graft (SVG) percutaneous coronary intervention (PCI) currently accounts for approximately 6 % of all PCIs and is associated with increased risk for distal embolization and subsequent SVG failure compared with native coronary artery PCI. To minimize the risk for distal embolization, embolic protection devices should be used during SVG PCI when technically feasible. To minimize the risk for in-stent restenosis and the need for repeat PCI, drug eluting stents should be utilized in patients without contraindications to long-term antiplatelet therapy. Treating native coronary artery lesions is preferable to SVG PCI when technically feasible.

Low molecular weight dextran provides similar optical coherence tomography coronary imaging compared to radiographic contrast media.

BACKGROUND: Optical coherence tomography (OCT) coronary imaging requires displacement of red blood cells from the vessel lumen. This is usually accomplished using radiographic contrast. Low molecular weight dextran has low cost and is safe in low volumes. In the present study, we compared dextran with contrast for coronary OCT imaging. METHODS: Fifty-one vessels in 26 patients were sequentially imaged using manual injection of radiographic contrast (iodixanol) and dextran. OCT images were analyzed at 1 mm intervals to determine the image clarity (defined as a visible lumen border > 270°) and to measure the lumen area and lumen diameter. To correct for the refractive index of dextran, the dextran area measurements were multiplied by 1.117 and the dextran length measurements were multiplied by 1.057. RESULTS: A total of 3,418 cross-sections (1,709 with contrast and 1,709 with dextran) were analyzed. There were no complications related to OCT imaging or to contrast or dextran administration. Clear image segments were observed in 97.0% vs. 96.7% of the cross-sections obtained with contrast and dextran, respectively (P = 0.45). The mean lumen areas were also similar: 6.69 ± 1.95 mm(2) with iodixanol vs. 7.06 ± 2.06 mm(2) with dextran (correlation coefficient 0.984). CONCLUSIONS: The image quality and measurements during OCT image acquisition are similar for dextran and contrast. Dextran could be used instead of contrast for OCT imaging, especially in patients in whom contrast load minimization is desired.

Influence of chronic total occlusions on coronary artery bypass graft surgical outcomes.

BACKGROUND: Presence of epicardial coronary artery chronic total occlusion (CTO) predicts higher referral rates for coronary bypass graft surgery (CABG). However, the impact of coronary artery CTO on CABG outcomes has never been systematically studied. METHOD: We examined one-year outcomes in 605 consecutive Veterans, discharged post-CABG between June 2005 and December 2008. RESULTS: A coronary CTO was present in 256 patients (42%), predominantly (48.3%) in the right coronary artery distribution. Baseline clinical characteristics and medical therapy were similar in patients with and without a coronary CTO. A single CTO was present in 73.8%, and 26.2% patients had multiple CTO. All left anterior descending coronary artery CTO were successfully bypassed, as were >92% in left circumflex and right coronary arteries and 85% CTO in multiple coronary artery distributions. During the mean follow-up of 348.9 ± 4.5 days, incidence of all-cause death and myocardial infarction were similar in both groups (7.1% in CTO group and 7.4% in non-CTO group; p = 0.97). CTO >20 mm in length constituted 74.9% and >40 mm 37.8%. One-year survival post-CABG was significantly lower in patients with CTO lengths >40 mm compared to ≤20 mm (p = 0.04). CTO >40 mm was an independent predictor of post-CABG mortality controlling for age, number of CTO, comorbid diseases, clopidogrel use, severity of coronary artery disease, renal failure, and left ventricular ejection fraction. CONCLUSION: CABG achieves high success in grafting epicardial coronary vessels with CTO; however, presence of long coronary CTO (>40 mm) is an independent predictor of post-CABG survival.

Plasma adiponectin levels are related to obesity, inflammation, blood lipids and insulin in type 2 diabetic and non-diabetic Trinidadians

AIMS: To determine the relationship between plasma adiponectin levels and obesity, inflammation, blood lipids and insulin resistance in type 2 diabetics (T2DM) and non-diabetics in a patient population in Trinidad. METHODS: A cohort study of a total of 126 type 2 diabetic (42 males and 84 females) and 140 (43 males and 97 females) non-diabetic public clinic attendees were assessed between December 2008 and July 2009. Along with clinical history and anthropometry, adiponectin, TNF-α, IL-6, CRP, lipid profile, glucose, and insulin were measured in fasting blood samples and insulin resistance (HOMA-IR) was calculated. RESULTS: Diabetics had higher (p<0.05) glucose, insulin, HOMA-IR, triglycerides (TG), VLDL and systolic blood pressure than non-diabetics, but lower (p<0.05) HDL and adiponectin levels. Adiponectin levels were lower (p<0.05) in obese than in non-obese individuals regardless of diabetic status. There were significant gender differences in HDL, LDL and TG. Among non-obese persons, adiponectin correlated negatively with triglycerides (r=-0.280; adiponectin), IL-6 (r=-0.216; p<0.005), HOMA-IR (r=-0.373; p=000) and positively correlated with HDL (r=0.355; p=0.000). Diabetic status (p=0.025), TNF-α (p=0.048) and BMI (p=0.027) were identified as useful predictors of adiponectin by multiple linear regression methods. In addition binary logistic regression analysis found glucose (p=0.001) and adiponectin (p=0.047) to be useful indicators of type 2 diabetes. CONCLUSIONS: Adiponectin decreases with increasing adiposity and insulin resistance. Adiponectin and TNF-α appear to be related to differences in the insulin mediated glucose turnover.
