Design of experiments to evaluate pH and temperature parameters with different inoculums in domestic biodigester.

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.

Improved overall survival in patients developing endocrine toxicity during treatment with nivolumab for advanced non-small cell lung cancer in a prospective study.

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.

Digital technology in maize nutrient management research in northern Nigeria amid COVID-19 pandemic.

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.

Development of a Framework for the Communication System Based on KNX for an Interactive Space for UX Evaluation.

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.

Water entrepreneurship and financialisation: Complexities for the attainment of SDG in sub-Saharan Africa.

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.

FACTORS AFFECTING RESEARCH ENGAGEMENT AMONG CLINICIANS IN AZARE, BAUCHI STATE, NIGERIA.

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.

Método y análisis Estudio retrospectivo de corte transversal en el que se incluyeron pacientes con glaucoma de ángulo abierto sometidos a trabeculectomía ab-externo modificada como primer tratamiento quirúrgico filtrante entre enero de 2008 a marzo de 2015. En el postoperatorio se evaluó la PIO, los medicamentos hipotensores, los tratamientos adicionales y las complicaciones tempranas y tardías. Resultados Se analizaron datos de 48 ojos de 38 pacientes. La media de edad fue de 63,1 años (25 a 85 años) y el tiempo medio de seguimiento fue de 35,3 meses (rango: 1-147 meses). La PIO preoperatoria media fue de 25,21±3,48mmHg y de 15,83±4,4mmHg al final del seguimiento. Catorce ojos (29%) requirieron goniopunción con láser y 4 ojos needling (8,4%). El análisis de supervivencia de Kaplan-Meier mostró una tasa de éxito del 81,7% a los 2 años y del 54,9% del año 4 al año 12. Dos ojos presentaron desprendimiento coroideo, 3 ojos cataratas que requirieron cirugía y 5 ojos tuvieron fugas tempranas de la ampolla. Conclusiones La trabeculectomía ab-externo modificada es eficaz para el tratamiento del glaucoma de ángulo abierto con un buen control de la PIO a largo plazo y una baja incidencia de complicaciones quirúrgicas, y podría utilizarse en casos complejos seleccionados de acuerdo con los resultados obtenidos (AU)

Objective Assess the safety and efficacy of a modified ab-external 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 follow-up time was 35.3 months (range of 1-147 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 (AU)

Profile of Acute Poisoning among Adult Patients at the Emergency Room of a Tertiary Hospital, South-western Nigeria.

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.

CAMKK2 is upregulated in primary human osteoarthritis and its inhibition protects against chondrocyte apoptosis.

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.

Clinical usefulness of serum angiotensin converting enzyme in silicosis.

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.

Incidence and sociodemographic, living environment and maternal health associations with stillbirth in a tertiary healthcare setting in Kano, Northern Nigeria.

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.

Impact on grafted kidney function of rocuronium-sugammadex vs cisatracurium-neostigmine strategy for neuromuscular block management. An Italian single-center, 2014-2017 retrospective cohort case-control study.

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.

Niveles séricos de PAPP-A y beta-hCG en el primer trimestre del embarazo como predictores de resultados obstétricos desfavorables en el Hospital Universitario Nuestra Señora de Candelaria / Serum levels of PAPP-A and beta-hCG in the first trimester of pregnancy as predictors of unfavourable obstetric outcomes at Hospital Universitario Nuestra Señora de Candelaria

Muchos estudios han documentado la asociación entre valores bajos de PAPP-A y β-hCG en el suero materno durante el primer trimestre, así como efectos materno-fetales adversos.Para valorar dicha relación, en nuestro medio se llevó a cabo un análisis retrospectivo de casos y controles anidado en una cohorte de pacientes con embarazo único en quienes se realizó el cribado del primer trimestre entre 2017 y 2018. Se consideraron casos aquellas pacientes con niveles de MoM PAPP-A y/o β-hCG iguales o inferiores al percentil 5, y como controles a una muestra aleatorizada de pacientes con niveles séricos por encima de dicho percentil.El análisis de nuestros resultados demostró que en los grupos con niveles bajos de MoM PAPP-A y MoM β-hCG se observó un mayor riesgo de desarrollar crecimiento intrauterino restringido que en el grupo control (OR: 2,7 y 3,17, respectivamente). En el grupo MoM PAPP-A≤p5 también se obtuvo un riesgo 3,8 veces superior de estados hipertensivos del embarazo (IC: 1,94-7,83) y 7,9 veces mayor de muerte fetal anteparto (IC:1,09-217,4). Estas dos variables no resultaron estadísticamente significativas en el grupo MoM β-hCG ≤p5.Nuestros hallazgos confirmaron que los niveles bajos de PAPP-A y β-hCG en el suero de las gestantes se asoció con un riesgo elevado de desarrollar complicaciones obstétricas, por lo que podrían utilizarse para la detección precoz de las mismas y prevención de malos resultados obstétricos.

Many studies have documented the association between low PAPP-A and β-hCG values in maternal serum during the first trimester and adverse maternal-foetal effects.To assess this relationship a retrospective analysis of cases and controls was carried out, based on a cohort of patients with a single pregnancy who underwent first-trimester screening between 2017 and 2018. For the group of cases, patients with MoM levels PAPP-A and/or β-hCG equal to or below the 5th percentile were selected. The control group was obtained by making a randomized selection of all patients with MoM PAPP-A levels and/or β-hCG above that percentile.The analysis of our results showed that in groups with low levels of MoM PAPP-A and MoM β- hCG, we observed a higher risk of developing restricted intrauterine growth than in the control group (OR: 2.7 and 3.17, respectively). In the MoM PAPP-A ≤p5 group we also obtained a 3.8-foldhigher risk of global hypertensive states of pregnancy (CI: 1.94-7.83) and 7.9-fold higher risk of antepartum foetal death (CI: 1.09- 217.4). These two variables were not statistically significant in the MoM β-hCG ≤p5 group.Our findings confirmed that low levels of PAPP-A and β-hCG in the serum of pregnant women are associated with a high risk of developing obstetric complications, so they could be used for their early detection and the prevention of poor obstetric results.

The variables of effectiveness and quality of life were evaluated at the beginning and at 4th week of treatment, calculating the difference in absolute terms between them.Results: We included 19 patients (11 women) with a median of 59 (IQR 11.4) years old and a BMI of 25.9 (IQR 6.0) kg/m2. All the patients showed a BSA <10% and were previously treated with topical treatments (74%; 14/19), acitretin (48%; 9/19) and immunosuppressants (26%; 5/19), among others. (AU)

Psychosocial consequences and reasons for illicit drug use among police officers in a northern Nigerian city: A mixed-method study

Harmful use of drugs is one of the principal risk factors affecting population health worldwide. Chronic use has been linked to medical, psychological and socioeconomic consequences. This study assessed the psychosocial consequences and reasons for illicit drug use among police officers in Kano, Nigeria. Using a mixed method of data collection, quantitative data was obtained from a cross-section of 275 officers using the Shortened Inventory of Problems-Drug Use (SIP­DU) and a pretested adapted questionnaire. In-depth interviews with 10 officers who used illicit drugs provided additional information. Almost half of the respondents (46.5%, n=128) were in their fourth decade of life with a mean age (±SD) of 35.1 ± 7.7 years. Over a quarter of the respondents (n=75) reported ever using illicit drugs, out of which 14.9% (n=41) were current users. Among the current drug users, 80.5% (n=33) attested to having money problems, 61.0% (n=25) agreed that they had spent too much money, and 56.1% (n=23) failed to do what was expected of them as a result of drug use and have hurt their family. Helping to stay awake and improving confidence were the major reasons (100%, n=41) for drug use mentioned by the respondents. The Nigerian Police Force should look into easing shifts and introducing stress-relieving activities. There is also the need to strengthen substance education and counselling and support officers with confidence issues, sleep disorders, and treat those with mood disorders.

Control de calidad en nutrición parenteral neonatal, empleando como método validado el análisis bioquímico / Quality control in neonatal parenteral nutrition, using biochemical analysis as a validated method

Objetivos: El objetivo de este estudio es describir el método empleado como control de calidad en las nutriciones parenterales de neonatos en un hospital de tercer nivel, así como realizar un análisis estadístico de los resultados del mismo.Material y métodos: En nuestro centro se realiza un análisis bioquímico de los niveles de glucosa, potasio y calcio de todas las nutriciones parenterales neonatales como método de control de calidad. Dicho análisis se realiza mediante técnicas previamente validadas. Se evaluaron todas las nutriciones parenterales neonatales elaboradas durante el periodo comprendido entre julio de 2018 y noviembre de 2019. Todas las mezclas analizadas contenían lípidos. Para el análisis estadístico de los resultados se consideró un ±10% sobre la concentración teórica como margen de aceptación.Resultados: Se analizaron 950 mezclas y se obtuvieron las rectas de regresión lineal para establecer la correlación entre el valor teórico y real de los componentes analizados.Conclusiones: Destaca la importancia que tiene el establecimiento de un control de calidad de las nutriciones parenterales neonatales, para la detección y prevención de errores durante la preparación de las mismas y previamente a su dispensación.

Objectives: We aimed to describe the method used as neonatal parenteral nutrition quality control in a third level hospital, as well as to carry on a statistical analysis of its results.Methods: In our center, a biochemical analysis of glucose, potassium and calcium levels of all neonatal parenteral nutrition is performed as a quality control method. This analysis is carried out using previously validated techniques. All neonatal parenteral nutrition prepared during the period between July 2018 and November 2019 were evaluated. All the mixtures analyzed contained lipids. For the statistical analysis of the results, ±10% of the theoretical concentration was considered as the acceptance margin.Results: 950 mixtures were analyzed and linear regression lines were obtained to establish the correlation between the theoretical and real value of the analyzed components.Conclusions: In conclusion, the importance of establishing quality control of neonatal parenteral nutrition is highlighted, for the detection and prevention of errors during their preparation and prior to their dispensing.
