RESUMO

The comprehensive management of organic urban solid waste is a concern due to its direct and indirect impact on the environment. Anaerobic Digestion (AD) has been recognized as an alternative and environmentally friendly technology for waste disposal, converting them into organic fertilizers and renewable energy. This research presents an experiment involving four reactors fed with household organic waste, three inoculated with canine, goat, and rabbit manure, and one without inoculum. The experiment was observed for 30 consecutive days to analyze the pH and temperature parameters involved in the AD process in domestic reactors. Statistical methodology, including one-way analysis of variance for assessing the effect of the type of inoculum, Tukey's simultaneous confidence intervals for mean differences, and 90 % confidence intervals for µ in temperature and manure, was utilized. Additionally, main effects analysis of the factors of average temperature and pH were conducted. The results of the one-factor experiment show that the type of inoculum does not significantly influence the variation in pH, while temperature remains relatively stable throughout the AD process. However, the analysis of main effects indicates that goat manure tends to stabilize the temperature with minimal variation, whereas variation is more heterogeneous in the other experiments.

RESUMO

The COVID-19 pandemic has been a life threatening and spreads wildly with physical human contact. Physical distancing is recommended by health experts to prevent the spread; thus, agronomic research has to be designed in conformity to this preventive standard during the pandemic. Consequently, this study was designed to evaluate the reliability of using digital tools in nutrient management research amid the COVID-19 pandemic in northern Nigeria. Fifty extension agents (EAs) were selected across 15 LGAs of Kaduna and Kano states. The EAs were trained on how to generate fertilizer recommendation using an android mobile phone-based nutrient expert (NE), to measure farmers' field sizes using UTM Area measure mobile phone app, and open data kit to record, submit and aggregate data during the exercise. Each EA covered 50 farms, where two nutrient management practices-one determined by the farmers: farmer fertilizer practice (FFP), and the other generated using the NE were evaluated. Results show that around 90% of the farmers have an average field size of 1.13 ha. All selected farmers used improved maize varieties for planting, among which 21% been able to use the exact recommended or lower seed rate. Use of inorganic fertilizer was 33% higher than the average recommended NE rate, while average yield of the NE fields was 48% higher than for the FFP. The results of this study indicate that yield can be improved with site-specific nutrient management (SSNM) extension approach. The SSNM using digital tools as the NE seem promising and befits to agronomic research in northern Nigeria amid the COVID-19 pandemic.

RESUMO

PURPOSE: Immune checkpoint inhibitors (ICPIs) disrupting PD-1/PD-L1 axis have revolutionized the management of advanced non-small cell lung cancer (NSCLC). Some studies identified the development of endocrine toxicity as predictor of better survival in cancer patients treated with ICPIs. The aim of study was to evaluate survival and new onset of immune-related endocrine adverse events (irAEs) in patients treated with nivolumab for advanced NSCLC. METHODS: In a prospective study, 73 patients with previously treated advanced NSCLC received nivolumab in monotherapy. Blood samples were collected at each cycle to monitor thyroid autoimmunity, thyroid, adrenal and somatotroph axes, while thyroid morphology was evaluated by ultrasonography. RESULTS: An impaired thyroid function was recorded in 23.4% of patients (n = 15). Eight patients developed asymptomatic transient thyrotoxicosis (ATT) evolving to hypothyroidism in 50% of cases. In addition, seven patients developed overt hypothyroidism without ATT and with negative autoantibodies. Patients who developed hypothyroidism proved to have better overall survival (OS) as compared with non-developers at both univariate (p = 0.021) and multivariate analyses (p = 0.023). The survival curve of patients with reduced IGF-I at baseline, or displaying its reduction during the follow-up, showed significantly reduced median survival compared to patients with normal/high IGF-I levels (p = 0.031). CONCLUSIONS: Thyroid function abnormalities are the major irAEs in patients treated with nivolumab, and hypothyroidism onset is associated with prolonged survival. Our findings indicate that the development of hypothyroidism is a positive predictive biomarker of nivolumab antitumor efficacy in patients with NSCLC. Low IGF-I levels could represent a negative prognostic factor during nivolumab therapy.

RESUMO

Domotics (Home Automation) aims to improve the quality of life of people by integrating intelligent systems within inhabitable spaces. While traditionally associated with smart home systems, these technologies have potential for User Experience (UX) research. By emulating environments to test products and services, and integrating non-invasive user monitoring tools for emotion recognition, an objective UX evaluation can be performed. To achieve this objective, a testing booth was built and instrumented with devices based on KNX, an international standard for home automation, to conduct experiments and ensure replicability. A framework was designed based on Python to synchronize KNX systems with emotion recognition tools; the synchronization of these data allows finding patterns during the interaction process. To evaluate this framework, an experiment was conducted in a simulated laundry room within the testing booth to analyze the emotional responses of participants while interacting with prototypes of new detergent bottles. Emotional responses were contrasted with traditional questionnaires to determine the viability of using non-invasive methods. Using emulated environments alongside non-invasive monitoring tools allowed an immersive experience for participants. These results indicated that the testing booth can be implemented for a robust UX evaluation methodology.

RESUMO

This study explores the potential of water financialisation and entrepreneurship in sub-Saharan Africa (SSA) to supplant the traditional responsibility of national, state, and local governments in providing public water supply, aligning with SDG Goals. Despite its typical association with the global north, a shifting landscape reveals emerging financial actors and multinational companies playing a more prominent role, prompting governance and accountability inquiries. Given the dearth of investment and persisting challenges in SSA's water infrastructure, the burgeoning involvement of financial actors and capital management entities in the water cycle seems inevitable. However, this trend raises concerns about exacerbating global water stress. Through qualitative methods, the study engaged 50 SSA participants via open-ended questionnaires, analysed using thematic analysis. The findings underscore a nuanced perspective. While acknowledging the potential of water financialisation and entrepreneurship to drive essential investment in SSA's water sector, the research emphasizes the irreplaceable role of government in policy execution and safeguarding citizens' well-being. Government intervention remains crucial to ensuring equitable water access and sustainability. Additionally, the analysis suggests that overemphasizing water financialisation could divert attention from critical infrastructural and technological advancements needed in SSA's water sector. This underscores the necessity of a balanced and comprehensive approach to address the multifaceted challenges surrounding water availability, governance, and sustainability in the region.

RESUMO

Introduction/Background: Medical research is a key element in the advancement of medicine and patient care improvement. However, there is evidence that developing regions like Nigeria have comparatively low research output. Clinicians' attitudes, practices, and barriers toward research are key causal factors of the low research productivity. Objectives: This study explored the research practice, attitude, and barriers towards research engagement among Clinicians at Federal Medical Centre, Azare, Bauchi state. Methodology: This was a quantitative cross-sectional study conducted at Federal Medical Centre, Azare, Bauchi state. Data on sociodemographic characteristics, research practices, attitudes, and barriers toward research engagement was obtained using a pretested, self-administered questionnaire. Data was collated and analyzed using IBM Statistical Package for Social Sciences software (SPSS) version 21. Result: A total of 101 clinicians participated in this study of which 14.9%, 31.7%, and 29.7% were Consultants, Registrars and Medical Officers respectively. Only 20.8% of the respondents have presented at a scientific conference previously, while 18.8% of the respondents have a published paper in a scientific journal. Although clinicians showed a positive attitude towards research (Mean: 4.39, SD ± 0.61), lack of research funding, facilities, mentorship, and demanding clinical services are major deterrents to clinicians' engagement in research. Conclusion: Clinicians have poor research practice despite their positive attitude towards research engagement. Appropriate interventions should be implemented for effective research engagement to augment research output.

RESUMO

BACKGROUND AND OBJECTIVE: Acute poisoning often presents as an acute medical condition necessitating prompt medical care. Few data exist on adult poisoning and management protocol often are inadequate. Assessing the cases may inform a more robust protocol for case management, necessitating this study. The objective was to assess cases of acute poisoning and determine the agents as well as their outcomes. METHODS: This was a retrospective study involving 53 adult cases of acute poisoning at the emergency room (ER) of a tertiary hospital over 5 years (2016­2020). The ER register was assessed for the gender, type of agent and outcome of the medical condition. Cases admitted to the ward were followed up to determine their outcomes. RESULTS: There were more males, 34 (64.2%) than females. 19 (35.8%) with a mean age of 29.2 ± 13.5 years and 24.6 ± 8.2 years respectively. Organophosphates accounted for 22 (41.5%) of cases followed by a cocktail of unknown mixture in 12 (22.6%) and paraquat in 6 (11.3%) cases. Alcohol, medications, and alkali were responsible for 5 (9.5%), 4 (7.5%) and 4 (7.5%) cases respectively. Mortality was recorded in 11 (20.8%) of cases this was mostly associated with paraquat. In addition, 1 (1.9%) case was referred to another facility while 2 (3.8%) cases required longer hospital stay. More than 50% of the cases were discharged within 24 to 48 hours while 6 (11.3%) cases were discharged against medical advice. CONCLUSION: Organophosphate appears to be the most common agent responsible for acute poisoning in adults in this environment and young male adults have a higher risk. Most of the poisoning cases were discharged however, mortality was high, particularly among those with paraquat poisoning.


CONTEXTE ET OBJECTIF: L'intoxication aiguë se présente souvent comme une condition médicale aiguë nécessitant des soins médicaux rapides. Il existe peu de données sur l'empoisonnement chez les adultes et le protocole de gestion est souvent inadéquat. L'évaluation des cas peut éclairer un protocole plus robuste pour la gestion des cas, ce qui nécessite cette étude. L'objectif estd'évaluer les cas d'intoxication aiguë et de déterminer les agents ainsi que leurs résultats. MÉTHODES: Il s'agissait d'une étude rétrospective portant sur tous les cas d'intoxication aiguë auxurgences d'un hôpital tertiairesur une période de 5 ans (2016-2020). Le registre des urgences a été évalué pour le sexe, le type d'agent et l'issue de l'état de santé. Les cas renvoyés au service ont fait l'objet d'un suivi pour déterminer les résultats. RÉSULTATS: La proportion de bières était plus élevée que celle des femmes (64,2 % contre 35,8 %) avec un âge moyen de 29,2 ±13,5 ans et 24,6 ±8,2 ans respectivement. L'organophosphate représentait 41,5 % des cas, suivi du mélange cocktail (22,6 %) et du paraquat (11,3 %). L'alcool, les drogues et les alcalis étaient responsables de 9,4 %, 7,6 % et 7,5 % respectivement. Mortalité wtelle qu'enregistrée dans 20. 8 % des cas; 1,9 % ont été référés tandis que 3,8 % ont dû rester plus longtemps à l'hôpital. Plus de 50 % des cas ont reçu leur congé dans les 24 à 48 heures, tandis que 11,3 % ont reçu leur congé contre avis médical. Le paraquat était le plus souvent responsable de la mort, tandis que l'alcool, les alcalis et les opioïdes avaient le même taux de mortalité. Neuf (17,0 %) des 11 (20,8 %) mortalités étaient des hommes CONCLUSION: La mortalité par intoxication aiguë est élevée et l'empoisonnement au paraquat est l'agent le plus mortel suivi par l'organophosphate. Les jeunes hommes sont prédisposés à l'empoisonnement par l'organophosphate ou le paraquat pour lesquels la mortalité est élevée. Mots-clés: Empoisonnement, Paraquat, Urgence, Organophosphate, MMortalité.

RESUMO

OBJECTIVE: Assess the safety and efficacy of a Modified Ab-externo Trabeculectomy surgical technique in controlling intraocular pressure (IOP) in open-angle glaucoma patients. METHODS AND ANALYSIS: Patients diagnosed with primary or secondary open-angle glaucoma underwent this modified technique as the first filtering surgical treatment were included. The preoperative and final follow-up assessed IOP, hypotensive medications, the need for additional treatments, and early and late complications. RESULTS: Forty-eight eyes of 38 patients were included. The mean age was 63.1 years (25-85 years), and the mean follow-up time was 35.3 months (range of 1147 months). The mean preoperative IOP was 25.21±3.48mmHg and 15.83±4.4mmHg by the follow-up end. Subsequent laser goniopuncture was performed on 14 eyes (29%) and needling in 4 eyes (8.4%). Complete success was achieved in 18 eyes (37.5%), qualified success in 17 (35.4%), and failed in 13 eyes (27.1%). Kaplan-Meier survival analysis shows a success rate of 81.7% at two years and 54.9% from year 4 to year 12. Multivariate analysis with generalized estimating equations (GEE) shows younger age as the main predictor for failure. Two eyes had choroidal detachment, three eyes progressed to cataracts that needed surgery, and five eyes had early bleb leaks. CONCLUSIONS: This proposed technique is an effective surgical procedure for treating open-angle glaucoma with effective long-term IOP control and a low incidence of surgical complications and could be used in selected complex cases based on these results.

RESUMO

OBJECTIVE: To investigate the role of calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2) in human osteoarthritis. MATERIALS AND METHODS: Paired osteochondral plugs and articular chondrocytes were isolated from the relatively healthier (intact) and damaged portions of human femoral heads collected from patients undergoing total hip arthroplasty for primary osteoarthritis (OA). Cartilage from femoral plugs were either flash frozen for gene expression analysis or histology and immunohistochemistry. Chondrocyte apoptosis in the presence or absence of CAMKK2 inhibition was measured using flow cytometry. CAMKK2 overexpression and knockdown in articular chondrocytes were achieved via Lentivirus- and siRNA-mediated approaches respectively, and their effect on pro-apoptotic and cartilage catabolic mechanisms was assessed by immunoblotting. RESULTS: CAMKK2 mRNA and protein levels were elevated in articular chondrocytes from human OA cartilage compared to paired healthier intact samples. This increase was associated with elevated catabolic marker matrix metalloproteinase 13 (MMP-13), and diminished anabolic markers aggrecan (ACAN) and type II collagen (COL2A1) levels. OA chondrocytes displayed enhanced apoptosis, which was suppressed following pharmacological inhibition of CAMKK2. Levels of MMP13, pSTAT3, and the pro-apoptotic marker BAX became elevated when CAMKK2, but not its kinase-defective mutant was overexpressed, whereas knockdown of the kinase decreased the levels of these proteins. CONCLUSIONS: CAMKK2 is upregulated in human OA cartilage and is associated with elevated levels of pro-apoptotic and catabolic proteins. Inhibition or knockdown of CAMKK2 led to decreased chondrocyte apoptosis and catabolic protein levels, whereas its overexpression elevated them. CAMKK2 may be a therapeutic target to prevent or mitigate human OA.

RESUMO

INTRODUCTION: Silicosis is an irreversible and incurable disease. Preventive measures to eliminate exposure are the only effective way to reduce morbidity and mortality. In such situations, having a biomarker for early diagnosis or to predict evolution would be very useful in order to improve control of the disease. The elevation of serum angiotensin-converting enzyme (sACE) in silicosis has been described in previous studies, although its relationship with severity and prognosis is not clear. AIMS: To determine the levels of sACE in a cohort of patients with exposure to silica dust with and without silicosis, and to assess their impact on the prognosis of the aforementioned patients. METHOD: Prospective observational study on patients treated in a silicosis clinic from 2009 to 2018. sACE levels and pulmonary function tests were performed. Radiological progression was assessed in patients who had already had 2 X-rays of the thorax and / or two CT scans with at least a 1-year interval, from the time of inclusion in the study. RESULTS: A total of 413 cases of silicosis were confirmed, as well as 73 with exposure to silica dust but without silicosis. The mean sACE level for healthy subjects was 27.5±7.3U/L, for exposed patients without silicosis it was 49.6±24.2U/L, for simple silicosis it was 57.8±31,3U/L and for complicated silicosis it was 74.5±38.6U/L. Patients with a higher sACE generally progressed radiologically during follow-up (73.3±38.0 vs. 60.4±33.7; p<.001) and so the category of silicosis changed (73,9±38.1 vs. 62.5±34.6; p<.021). CONCLUSIONS: sACE was elevated in patients with silicosis, and the greater its severity, the higher it was, which is associated with disease progression measured radiologically or as a category change of silicosis.

RESUMO

BACKGROUND: Almost two million stillbirths occur annually, most occurring in low- and middle-income countries. Nigeria is reported to have one of the highest stillbirth rates on the African continent. The aim was to identify sociodemographic, living environment, and health status factors associated with stillbirth and determine the associations between pregnancy and birth factors and stillbirth in the Murtala Mohammed Specialist Hospital, Kano, Nigeria. METHODS: A three-month single-site prospective observational feasibility study. Demographic and clinical data were collected. We fitted bivariable and multivariable models for stillbirth (yes/no) and three-category livebirth/macerated stillbirth/non-macerated stillbirth outcomes to explore their association with demographic and clinical factors. FINDINGS: 1,998 neonates and 1,926 mothers were enrolled. Higher odds of stillbirth were associated with low-levels of maternal education, a further distance to travel to the hospital, living in a shack, maternal hypertension, previous stillbirth, birthing complications, increased duration of labour, antepartum haemorrhage, prolonged or obstructed labour, vaginal breech delivery, emergency caesarean-section, and signs of trauma to the neonate following birth. INTERPRETATION: This work has obtained data on some factors influencing stillbirth. This in turn will facilitate the development of improved public health interventions to reduce preventable deaths and to progress maternal health within this site.

RESUMO

BACKGROUND: The impact of sugammadex in patients with end-stage renal disease undergoing kidney transplantation is still far from being defined. The aim of the study is to compare sugammadex to neostigmine for reversal of rocuronium- and cisatracurium-induced neuromuscular block (NMB), respectively, in patients undergoing kidney transplantation. METHODS: A single-center, 2014-2017 retrospective cohort case-control study was performed. A total of 350 patients undergoing kidney transplantation, equally divided between a sugammadex group (175 patients) and a neostigmine group (175 patients), were considered. Postoperative kidney function, evaluated by monitoring of serum creatinine and urea and estimated glomerular filtration rate (eGFR), was the endpoint. Other endpoints were anesthetic and surgical times, post-anesthesia care unit length of stay, postoperative intensive care unit admission, and recurrent NMB or complications. RESULTS: No significant differences in patient or, with the exception of drugs involved in NMB management, anesthetic, and surgical characteristics, were observed between the two groups. Serum creatinine (median [interquartile range]: 596.0 [478.0-749.0] vs 639.0 [527.7-870.0] µmol/L, p = 0.0128) and serum urea (14.9 [10.8-21.6] vs 17.1 [13.1-22.0] mmol/L, p = 0.0486) were lower, while eGFR (8.0 [6.0-11.0] vs 8.0 [6.0-10.0], p = 0.0473) was higher in the sugammadex group than in the neostigmine group after surgery. The sugammadex group showed significantly lower incidence of postoperative severe hypoxemia (0.6% vs 6.3%, p = 0.006), shorter PACU stay (70 [60-90] min vs 90 [60-105] min, p < 0.001), and reduced ICU admissions (0.6% vs 8.0%, p = 0.001). CONCLUSIONS: Compared to cisatracurium-neostigmine, the rocuronium-sugammadex strategy for reversal of NMB showed a better recovery profile in patients undergoing kidney transplantation.

RESUMO

P2X7 receptor promotes inflammatory response and neuropathic pain. New drugs capable of impairing inflammation and pain-reducing adverse effects extracted from plant extracts have been studied. Physalis angulate L. possesses traditional uses and exhibits antiparasitic, anti-inflammatory, antimicrobial, antinociceptive, antimalarial, antileishmanial, immunosuppressive, antiasthmatic. diuretic, and antitumor activities. The most representative phytochemical constituents identified with medicinal importance are the physalins and withanolides. However, the mechanism of anti-inflammatory action is scarce. Although some physalins and withanolides subtypes have anti-inflammatory activity, only four physalins subtypes (B, D, F, and G) have further studies. Therefore, we evaluated the crude ethanolic extract enriched with physalins B, D, F, and G from P. angulata leaves, a pool containing the physalins B, D, F, G, and the physalins individually, as P2X7 receptor antagonists. For this purpose, we evaluated ATP-induced dye uptake, macroscopic currents, and interleukin 1-ß (IL-1ß) in vitro. The crude extract and pool dose-dependently inhibited P2X7 receptor function. Thus, physalin B, D, F, and G individually evaluated for 5'-triphosphate (ATP)-induced dye uptake assay, whole-cell patch-clamp, and cytokine release showed distinct antagonist levels. Physalin D displayed higher potency and efficacy than physalin B, F, and G for all these parameters. In vivo mice model as ATP-induced paw edema was potently inhibited for physalin D, in contrast to physalin B, F, and G. ATP and lipopolysaccharide (LPS)-induced pleurisy in mice were reversed for physalin D treatment. Molecular modeling and computational simulation predicted the intermolecular interactions between the P2X7 receptor and physalin derivatives. In silico results indicated physalin D and F as a potent allosteric P2X7 receptor antagonist. These data confirm physalin D as a promisor source for developing a new P2X7 receptor antagonist with anti-inflammatory action.

RESUMO

OBJECTIVE: The objective of this study is to analyse the current system of virtual consultations between the levels of Primary and Specialised Care in the field of Traumatology and Orthopaedic Surgery (TOS) in our healthcare area. MATERIAL AND METHOD: A retrospective observational study was carried out on 90 consecutive patients who had a non-face-to-face consultation between 3 January 2017 and 10 February 2017 and subsequently a face-to-face consultation. All the patients belonged to the same healthcare area attached to the Nuestra Señora de Candelaria University Hospital. The data on the diagnostic orientation, medical history provided and complementary tests were evaluated by 2 observers, one with training in Family and Community Medicine and the other with specialised training in TOS, and compared with those obtained in the final face-to-face assessment. RESULTS: The results showed a low inter-judge agreement regarding the diagnostic orientation, anamnesis, exploration and complementary tests provided in the virtual consultation request. It was considered that only 59% for one observer (Family and Community Medicine) and 47.7% for the other (specialised care) had sufficient information for decision-making. Furthermore, 35.2% required more than one face-to-face assessment consultation until diagnosis and in 45.5% it was necessary to request new complementary tests. In 30.7%, there was no concordance in the suggested and final diagnosis. In 51.9%, no therapeutic action other than that carried out by Primary Care was carried out and 34.1% of the patients were referred to the Rehabilitation department. CONCLUSIONS: The current model of virtual consultations in TOS does not seem adequate to respond to this new healthcare model. The number of unnecessary referrals is very high despite the previous virtual assessment by a specialist in TOS. The Family and Community Medicine specialist should have more diagnostic resources and coordination between Primary and Specialised Care is necessary to determine, in the area of TOS, the type of consultations and conditions for which this system should be implemented to obtain adequate coordination and improve communication between both levels of care.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has been proposed as a disease of accelerated aging. Several cross-sectional studies have related a shorter telomere length (TL), a marker of biological aging, with COPD outcomes. Whether accelerated telomere shortening over time relates to worse outcomes in COPD patients, is not known. METHODS: Relative telomere length (T/S) was determined by qPCR in DNA samples from peripheral blood in 263 patients at baseline and up to 10 years post enrolment. Yearly clinical and lung function data of 134 patients with at least two-time measures of T/S over this time were included in the analysis. RESULTS: At baseline, T/S inversely correlated with age (r = - 0.236; p < 0.001), but there was no relationship between T/S and clinical and lung function variables (p > 0.05). Over 10 years of observation, there was a median shortening of TL of 183 bp/year for COPD patients. After adjusting for age, gender, active smoking and mean T/S, patients that shortened their telomeres the most over time, had worse gas exchange, more lung hyperinflation and extrapulmonary affection during the follow-up, (PaO2 p < 0.0001; KCO p = 0.042; IC/TLC p < 0.0001; 6MWD p = 0.004 and BODE index p = 0.009). Patients in the lowest tertile of T/S through the follow-up period had an increased risk of death [HR = 5.48, (1.23-24.42) p = 0.026]. CONCLUSIONS: This prospective study shows an association between accelerated telomere shortening and progressive worsening of pulmonary gas exchange, lung hyperinflation and extrapulmonary affection in COPD patients. Moreover, persistently shorter telomeres over this observation time increase the risk for all-cause mortality.

RESUMO

BACKGROUND: Anterior Cruciate Ligament (ACL) injuries may be accompanied by associated injuries such as meniscal injuries. Clinical evaluation alone may at times miss the diagnosis of ACL injury and one or more associated injuries. However, an adjuvant diagnostic tool such as an MRI of the knee may be unaffordable to some patients. The goal of this study was to compare the sensitivity, specificity and predictive value of clinical and magnetic resonance image (MRI) findings in the diagnosis of anterior cruciate ligament and meniscal injuries. METHODS: This was a prospective study. The cases of ACL injury recruited had a magnetic resonance imaging of the injured knee, and knee arthroscopy done. The clinical, magnetic resonance imaging and arthroscopic diagnostic findings were all noted. The sensitivity, specificity, positive predictive value and negative predictive values of clinical and MRI findings were compared, with arthroscopic findings as gold standard. RESULTS: A total of seventy-seven patients were recruited for the study. There were fifty-four males and twenty three females. The results of the tests of the sensitivity, specificity, positive predictive value and negative predictive value of clinical diagnosis and MRI when compared with arthroscopy findings, in detecting meniscal and anterior cruciate ligament injuries were as follows: For Clinical evaluation; Anterior Cruciate ligament: 81%, 80%, 86% and 76%; Medial Meniscus: 84%, 77%, 84% and 93%; and Lateral Meniscus: 85%, 77%, 85% and 82% respectively. For MRI: Anterior Cruciate Ligament (ACL): 87%, 89%, 93% and 78% ; Medial Meniscus: 87% 79%, 70% and 82%; and the Lateral Meniscus: 70%, 76% 73% and 72%. CONCLUSION: The specificity, sensitivity and predictive value of clinical and MRI findings were comparable in relation to the diagnosis of ACL and Medial Meniscus tears. However, the values of these parameters were better with clinical examination than with MRI in relation to the diagnosis of lateral meniscus tears.

RESUMO

There has been a recent increase in the consumption of cow's milk substitutes, specifically plant-based beverages, which have erroneously been named "plant milks". Plant-based beverages do not have a standard of identity, and so their nutritional composition can vary from one brand to another, even within the same category. The aim of the present narrative review was to produce a technical opinion to serve as a frame of reference for sustaining the recommendation of soy plant-based beverages. Nutrition and gastroenterology experts that belong to the Asociación Mexicana de Gastroenterología jointly commented on and analyzed themes on plant-based beverages, and on soy drinks in particular, including their nutritional characteristics, consumption in children, and potential growth and development alterations, as well as soy drink consumption in adults and its association with gastrointestinal alterations and other conditions. Plant-based beverages, including those made from soy, are not a replacement for breastmilk or breastmilk substitutes. Soy beverages are considered safe and can enrich the varied diet of its consumers, as long as they are considered an additional liquid portion of the diet. They can be ingested by adults and children above two years of age that present with cow's milk protein allergy or lactose intolerance.

RESUMO

BACKGROUND: Preterm babies have constituted a major constraints on human and material resources due to early mortality and long term disability among survivors. Rates of disability among survivors have increased over the period, with high rates of broncho-pulmonary dysplasia. OBJECTIVE: To determine the survival and management challenges of preterm babies in University of Maiduguri Teaching Hospital, Maiduguri Borno State REUSLTS: Of the 1129 preterm babies managed in the Special Care Baby Unit (SCBU), 714 cases notes were retrieved and analyzed giving a retrieval rate of 63%. There were 256 (35.9%) preterm babies as in-born, while 458 (64.1%) were out-born. Male preterm babies were 372 (52.1%), while female preterm babies were 342 (47.9%); with female to male ratio of 1.08:1. Extreme low birth weight (<1000grams) were 17 (2.3%), very low birth weight (1000-1499 grams) were 288 (40.3%) while low birth weight (1500-2499 grams) were 406 (56.9%). We also documented 3 preterm babies whose weights >2500 grams were large for gestational age weight. Duration of oxygen therapy (p = 0.620), duration of phototherapy (p = 0.474), and EBT (p = 0.466) showed no association with their survival while only duration of incubator care (p = 0.005) demonstrated significant association with outcome. CONCLUSION: The population of preterm babies studied is 32.70% and their survival has remarkably improved. However, this improved survival of preterm babies especially the extreme and very low birth weight categories has posed a big challenge due to limited access to incubator care, use of caffeine and surfactant which might influence the outcome.

RESUMO

Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Hepatitis E Virus (HEV) are highly endemic in several African countries including Nigeria with adverse effects on pregnancy outcomes resulting in fatality. This study aimed to determine the viral hepatitis in pregnant women attending antenatal clinic, AMTHI. Informed consent questionnaire was administered before blood collection via venipuncture. a total of 904 pregnant women plasma samples were tested for HBV, HCV, and HEV using ELISA kit. Data was analyzed using packages within SPSS software and P ≤ 0.05 was considered significant. Out of 904 samples analyzed, the overall prevalence of hepatitis infections among pregnant women attending antenatal clinic in AMTHI was 66(7.3%). High prevalence of the hepatitis infections was found among young women within the age group 21-30 which might be associated with active sex, intravenous drug use, sharing of sharp objects and alcoholism. Blood group O Positive had the highest prevalence of hepatitis. There was statistical significance between blood group and HBsAg infection (P < .05). Genotype AA women had highest prevalence of hepatitis. This study showed significant association between HBsAg, HCV, and HEV positive status with blood group O positive and Genotype AA pregnant women.
