Abstract

Context. Oxidative products take part in various physiological processes and overproduction of oxidative products is involved in the etiology of many diseases. Objectives. We aimed to evaluate thiol-disulfide homeostasis (TDH); one of the oxidative stress parameters, in girls with premature thelarche (PT) and precocious puberty (PP). Design. This case-control study was conducted between January 2022 and July 2022. Subjects and Methods. TDH parameters, involving native thiol (NT), disulfide, and total thiol (TT), were evaluated in 39 girls with PT, 41 girls with PP and 46 healthy prepubertal girls. The correlations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2) levels with the TDH parameters were determined and ROC curve analysis was performed. Results. NT, TT and NT/TT ratio were higher in the PT and PP groups compared to the control group (p<0.01). Disulfide/NT ratio and disulfide/TT ratio were lower in the PT and PP groups compared to the control group (p<0.05). All the TDH values did not statistically differ between the PP and PT group (p>0.05). There was a positive correlation between LH level, FSH level, and NT level, TT level, NT/TT ratio. The best parameter to discriminate PT or PT and control groups were NT and TT (p<0.01). Conclusion. TDH is altered in girls with PT and PP. NT and TT levels can be useful to discriminate prepubertal girls with lipomastia and girls with PP and PT in clinical practice. Further studies on larger cohorts of patients are required to clarify our results. [ABSTRACT FROM AUTHOR]

Abstract

Background: Vegetarian diets have grown in popularity partly because they have been linked to numerous health benefits. They are typically high in fiber and antioxidants and low in cholesterol, potentially lowering the risk of chronic diseases. On the other hand, diets established on meat and its products play a significant role in increasing the incidence of non-communicable diseases owing to their increased calorie density and extra saturated fat. Methods: A cross-sectional study was conducted among 121 adults recruited purposively from two Seventh-day Adventist churches in the Ede South Local Government area of Osun State. Results: Most respondents (73.6 %) were non-vegetarian and 26.4% were vegetarian (65.6% semi-vegetarian, 25% lacto-ovo, and 9.4% vegans). Among the non-vegetarians, 4.0% were underweight, 42.0% were of normal weight, 44.0% were overweight, and 10.1 % were obese. Among Vegetarians, 56.3% and 43.7% were of normal weight and overweight, respectively. Conclusion: The prevalence of obesity among non-vegetarians was high, indicating the need for nutritional education intervention on the health benefits of a vegetarian diet.

Abstract

In Nigeria, processing cassava for food and industry yields around 15 million tons of wet peels annually. These peels are usually dumped near processing centres to rot or dry enough to be burned. Rotting heaps release methane into the air and a stinking effluent that pollutes nearby streams and underground water, while burning produces clouds of acrid smoke. However, when properly dried, peels can be an ingredient in animal feed. Previous attempts over two decades to use peels in animal feed failed to yield profitable options for drying wet peels at commercial scale, but recent research suggests that cassava peels can be processed into high-quality cassava peel (HQCP) products to be used as nutritious, low-cost animal feed ingredients. The core innovation was to adopt the same steps and equipment used for processing cassava roots into gari, the main staple food in the country. When dried, 3 tons of wet peels yield a tonne of healthy and energy-rich animal feed, containing nearly 3,000 kilocalories per kilogram of dry matter (kcal/kgDM). Adopting this innovation at scale in Nigeria’s poultry and fish sectors alone has the potential to turn approximately 3.6 million tons of wet peels into 1.2 million tons of feed ingredients capable of replacing approximately 810,000 tons of largely imported maize. The innovation has great potential to increase feed availability and lower its cost while saving cereals for human consumption, reducing the import bill, creating new business opportunities, and protecting the environment. This research was initiated by CGIAR centres and taken up by the CGIAR Research Program on Roots, Tubers and Bananas (RTB) over the past decade with strategic input from the CGIAR Research Program on Livestock to accelerate development of the innovation, and this chapter documents the potential and progress in taking this innovation to scale.

Abstract

Abstract Central nervous system (CNS) metastases can be seen at a rate of 30% in advanced stages for patients with non-small cell lung cancer (NSCLC). Growing evidence indicates the predictive roles of driver gene mutations in the development of brain metastases (BM) in recent years, meaning that oncogene-driven NSCLC have a high incidence of BM at diagnosis. Today, 3rd generation targeted drugs with high intracranial efficacy, which can cross the blood–brain barrier, have made a positive contribution to survival for these patients with an increased propensity to BM. It is important to update the clinical and pathological factors reflected in the survival with real-life data. A multi-center, retrospective database of 306 patients diagnosed with driver mutant NSCLC and initially presented with BM between between November 2008 and September 2022 were analyzed. The median progression-free survival (mPFS) was 12.25 months (95% CI, 10–14.5). While 254 of the patients received tyrosine kinase inhibitor (TKI), 51 patients received chemotherapy as first line treatment. The median intracranial PFS (iPFS) was 18.5 months (95% CI, 14.8–22.2). The median overall survival (OS) was 29 months (95% CI, 25.2–33.0). It was found that having 3 or less BM and absence of extracranial metastases were significantly associated with better mOS and iPFS. The relationship between the size of BM and survival was found to be non-significant. Among patients with advanced NSCLC with de novo BM carrying a driver mutation, long-term progression-free and overall survival can be achieved with the advent of targeted agents with high CNS efficacy with more conservative and localized radiotherapy modalities.

Abstract

Background: This was a cross-sectional community-based survey to study the prevalence of serum antibodies against the severe acute respiratory syndrome coronavirus 1 (SARS-COV-1) and determine possible source of antibodies as to whether from vaccination or from natural infection as well as attempt to compare antibody levels in response to the different four types of vaccines administered in Nigeria. Methods: A cross-sectional community-based study of the prevalence of serum antibodies against all four vaccine types used in Nigeria amongst a representative sample of people aged 18 years and above in the six geopolitical zones of the country using a multistage sampling technique covering 12 states of the country with two states being randomly selected from each geopolitical zone. High-throughput Roche electrochemiluminescence immunoassay system (Elecsys Anti-SARS-COV-1 Cobas) was used for qualitative and quantitative detection of antibodies to SARS-COV-1 in human plasma. Results: There was no statistically significant difference between the proportions with seropositivity for both the vaccinated and the unvaccinated (P = 0.95). The nucleocapsid antibody (anti-Nc) titres were similar in both the vaccinated and the unvaccinated, whereas the Spike protein antibody (anti-S) titres were significantly higher amongst the vaccinated than amongst the unvaccinated. Antibody levels in subjects who received different vaccines were compared to provide information for policy. Conclusion: While only 45.9% of the subjects were reported to have been vaccinated, 98.7% of the subjects had had contact with the SARS-COV-1 as evidenced by the presence of nucleocapsid (NC) antibodies in their plasma. The 1.3% who had not been exposed to the virus, had spike protein antibodies which most likely resulted from vaccination in the absence of NC antibodies. Successive vaccination and booster doses either through heterogeneous or homologous vaccines increased antibody titres, and this stimulation of immune memory may offer greater protection against coronavirus disease 2019.

Abstract

Abstract Objective The standard method of generating disorder‐specific disability scores has lay raters make rankings between pairs of disorders based on brief disorder vignettes. This method introduces bias due to differential rater knowledge of disorders and inability to disentangle the disability due to disorders from the disability due to comorbidities. Methods We propose an alternative, data‐driven, method of generating disorder‐specific disability scores that assesses disorders in a sample of individuals either from population medical registry data or population survey self‐reports and uses Generalized Random Forests (GRF) to predict global (rather than disorder‐specific) disability assessed by clinician ratings or by survey respondent self‐reports. This method also provides a principled basis for studying patterns and predictors of heterogeneity in disorder‐specific disability. We illustrate this method by analyzing data for 16 disorders assessed in the World Mental Health Surveys (n = 53,645). Results Adjustments for comorbidity decreased estimates of disorder‐specific disability substantially. Estimates were generally somewhat higher with GRF than conventional multivariable regression models. Heterogeneity was nonsignificant. Conclusions The results show clearly that the proposed approach is practical, and that adjustment is needed for comorbidities to obtain accurate estimates of disorder‐specific disability. Expansion to a wider range of disorders would likely find more evidence for heterogeneity.

Abstract

Introduction: Resilience may be central to poststroke recovery. There is a knowledge gap on the predictors of resilience and its impact on mental health of Africans who survive a stroke. We describe the trajectory of psychological resilience and its association with depression and quality of life across the first poststroke year in Nigeria. Methods: Prospective observational study. Resilience was ascertained at 3 time-points prospectively over 12 months using the resilience scale. Depression and quality of life were also assessed at baseline and follow-up, respectively using centre for epidemiologic studies depression scale (CES-D 10) and health related quality of life in stroke patients (HRQOLISP-26). Trajectory was examined using the Greenhouse-Gaiser and Bonferoni corrected Analyses of variance. Associations were investigated using regression models and presented as adjusted odds ratios (aOR) and wald test coefficients within 95% confidence intervals (CI). Results: Of 150 consenting stroke survivors, 132 (88%) could be assessed for resilience. Resilience scores improved across time points of measurement (F-test=23.516, p

Abstract

In recent years, Mini/Micro UAVs have started to become a major concern and threat to the public, which made the need of detection and classification of them inevitable. Among all known detection techniques, one of the best reassuring and promising approach is utilizing the passive RF detection method. One of the major problems in this technique is detecting the threats in the presence of the other wireless interference signals like ISM Band Based or Spurious Signals. Proposed study handles this task using hybrid discrimination techniques both utilizing Signal Analysis/Decoding and Overlapping Signal Removal methods. In the first part of the technique, the captured signals are decoded to detect and get RF parameters of Wi-Fi signals and therefore the detected ones are removed from the corresponding spectrums in the time domain which prevents the miscalculation of the center frequency and bandwidth caused by overlapping Wi-Fi signals. In the second part of the technique, developed pulse on pulse (PoP) algorithms are employed in order to calculate more precisely the center frequency and bandwidth of the threat. Both methods developed on an SDR are experimented on both laboratory and field. By means of PoP Algorithms, the calculated deviation center frequency of the one of the Mini/Micro UAVs’ signal is improved from 103 ppm to 61.2 ppm in the presence of wideband overlapping spurious signals. The bandwidth correction is also achieved and makes the bandwidth to be calculated precisely. When Wi-Fi signals are decoded corresponding technique is applied additionally, in frequency domain, the center frequency estimation improved from 61.2 ppm to 28.5 ppm. These results show that the proposed method outperforms the results given in laboratory and field tests.

Abstract

(Co25Cr15Fe20Ni40)83Al17 is a eutectic high entropy alloy (EHEA), which is composed of face centered cubic (FCC) and body centered cubic (BCC) phases. This dual (FCC+BCC) phase mixture provides good ductility and strength combination. In the scope of this study, it was aimed to analyze the effect of mechanical, thermal and thermomechanical processes on the microstructure and hardness of (Co25Cr15Fe20Ni40)83Al17 EHEA, which was produced by the vacuum arc melting and casting method. With this aim, cold and hot rolling as well as different annealing treatments were applied to the as-cast plates. The cold-rolling was performed at room temperature while the hot rolling temperature was varied in between 500-1000℃. The maximum deformation that can be applied was 50% and 60 % after cold and hot rolling, respectively. The limited deformability was attributed to the increased BCC/B2 content in the eutectic phase mixture with the applied deformation. The hardness was increased from 280 HV to 412 HV after 50% cold-rolling. A similar high hardness value (399 HV) was obtained after ~50% deformation at 750℃, indicating that the dynamic recrystallization had no significant effect up to 1000℃.

Abstract

Factors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman) ; however, HCV-related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high-treatment rate will contribute to a reduction in total cases and HCV- related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV- related morbidity and mortality.

Abstract

The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets —“WHO Targets” (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.

Abstract

Background: Although chemotherapy-induced cardiotoxicity is an emerging problem, limited information is available on the effects of chemotherapy on left ventricular (LV) mechanical functions in patients with non-small cell lung cancer (NSCLC). Objective: We aimed to explore chemotherapy-induced alterations in cardiac mechanical functions in patients with NSCLC using speckle tracking echocardiography (STE). Methods: Seventy-one patients with NSCLC and 34 age and sex matched control subjects were consecutively included. Based on their good performance status (Eastern Cooperative Oncology Group performance status), 39 patients were treated with paclitaxel plus carboplatin (PC) regimen and 32 patients were treated with vinorelbine plus cisplatin (VC) regimen. All patients and controls underwent conventional two-dimensional echocardiography and STE at baseline to assess their LV functions. The echocardiographic examinations of NSCLC patients were repeated after the chemotherapy regimens. Results: None of the NSCLC patients developed any signs or symptoms of clinical heart failure during or after the chemotherapy. There were not any significant differences in LV ejection fraction between NSCLC patients and controls before and after chemotherapy. There were not any significant differences in baseline LV global longitudinal strain (GLS), radial strain (RS), and circumferential strain (CS) between NSCLC patients and controls. However, all LV GLS, RS and CS significantly decreased in patients treated with the PC regimen resulting in a significant difference compared to both VC group and controls while no significant decreases were observed in strain measures in VC group. Conclusion: Paclitaxel plus carboplatin, but not VC, may induce subclinical cardiotoxicity in patients with NSCLC, which may be detected by STE. Resumo: Introdução: Embora a cardiotoxicidade induzida pela quimioterapia seja um problema emergente, existe informação limitada sobre os efeitos da quimioterapia na função do ventrículo esquerdo (VE) em doentes com cancro do pulmão não de pequenas células (CPNPC). Objetivo: Avaliar alterações induzidas pela quimioterapia na função cardíaca em doentes com CPNPC utilizando a ecocardiografia de speckle tracking (EST). Métodos: Foram incluídos consecutivamente 71 doentes com CPNPC e 34 indivíduos caso controlo emparelhados por idade e género. Com base no seu desempenho (Eastern Cooperative Oncology Group performance status), 39 doentes foram tratados com regime de paclitaxel e carboplatina (PC) e 32 doentes foram tratados com regime de vinorelbina e cisplatina (VC). Todos os doentes e casos controlo foram submetidos a ecocardiografia bidimensional convencional (2DE) e a EST na fase basal para avaliar a função VE. As avaliações ecocardiográficas dos doentes com CPNPC foram repetidas após quimioterapia. Resultados: Nenhum dos doentes com CPNPC desenvolveu qualquer sinal ou sintoma clínico de insuficiência cardíaca durante ou após a quimioterapia. Não houve diferenças significativas na fração de ejeção do VE entre os doentes com CPNPC e os casos controlo antes e depois da quimioterapia. Não houve diferenças significativas nos valores basais da deformação longitudinal global do VE (GLS), deformação radial (RS) e deformação circunferencial (CS) do VE entre os doentes com CPNPC e os casos controlo. No entanto, todos os valores de deformação miocárdica VE diminuíram significativamente nos doentes tratados com o regime CP, resultando numa diferença significativa em comparação tanto com o grupo CV como com os casos controlo, embora não se tenham observado diminuições significativas nas medidas de strain no grupo VC. Conclusão: Apenas a PC, mas não a VC, pode induzir cardiotoxicidade subclínica em doentes com CPNPC, o que pode ser detetado por ecocardiografia de speckle tracking.

Abstract

Abstract Background Cervical cancer is the fourth most common cancer in women globally despite being a largely treatable and preventable malignancy. Developing countries account for over 80% of all new cases. Women residing in low-resource settings such as those residing in slums have a higher risk of cervical cancer, and lower uptake of cervical cancer screening. Diverse barriers influence the uptake of cervical cancer screening among women in low-resource settings. Objectives This qualitative study was done prior to the introduction of a cervical cancer screening program in two slum areas in Lagos Nigeria and explored women’s knowledge about cervical cancer, and their perceived barriers and recommendations for the program. Method Four focus group discussions(FGD) were conducted among 35 women between the ages of 21–65 years residing in two urban slums in Lagos, Nigeria from February to April 2019. Each FGD was limited to 8–10 participants of women of similar ages. Voice recordings were transcribed verbatim and thematic analysis was done. Results Most of the women were not aware of cervical cancer and none knew the symptoms or risk factors of cervical cancer. The participants felt that the cervical cancer screening program would be well accepted in the community, however, expressed concerns about the cost of the screening test and the sex of the person performing the test. The recommendations proffered for a successful cervical cancer screening program include; reducing the cost of the test or providing the test free of charge, having people that speak the local language as part of the team, using female health care providers, using a private location within the community or nearby primary health center, and publicizing the program with the use of SMS, phone calls, town crier, and health talks. It was recommended that organizing health education sessions would help improve women’s poorly perceived susceptibility to cervical cancer. Conclusion Interventions to increase uptake of cervical cancer screening among women in low resource settings need to improve knowledge of cervical cancer and address barriers to cervical cancer screening such as cost, distance, and as much as possible, sex of the healthcare provider should be considered.

Abstract

Abstract Background Taking advantage of the rapidly increasing access to digital technology in low- and middle-income countries, the World Health Organization has launched an electronic version of the mental health Gap Action Programme intervention guide (emhGAP-IG). This is suitable for use on smartphones or tablets by non-specialist primary healthcare providers (PHCWs) to deliver evidence-based intervention for priority mental, neurological and substance use disorders. We assessed the perceptions of PHCWs on the feasibility, acceptability, and benefits of using smartphone-based clinical guidance and the emhGAP-IG in the management of people with mental health conditions in Nigeria. Methods Exploration of the views of PHCWs from 12 rural and urban primary health clinics (PHCs) in South-Western Nigeria were carried out using 34 in-depth key informant qualitative interviews with nurses (n = 10), community health officers (n = 13) and community health extension workers (n = 11). An additional two focus group discussions, each comprising eight participants drawn from across the range of characteristics of PHCWs, were also conducted. Thematic analysis was conducted using a three-staged constant comparison technique to refine and categorise the data. Results Three overall themes were identified around the use of clinical guidance and mobile applications (apps) in PHCs. Apps were deployed for purposes other than clinical consultation and decision making. Although paper-based guidance was the expected practice, its utilization is not fully embedded in routine care. An app-based decision-making tool was preferred to paper by PHCWs. Future usage of the emhGAP-IG would be facilitated by training and supporting of staff, helpful design features, and obtaining patients’ buy-in. Conclusion Our findings suggest that the emhGAP-IG could be a viable way to embed clinical guidance and decision-making tools in the management of people with mental health conditions in Nigerian PHCs.

Abstract

Background: This study assessed the potential cost-effectiveness of high (80–100%) vs low (21–35%) fraction of inspired oxygen (FiO2) at preventing surgical site infections (SSIs) after abdominal surgery in Nigeria, India, and South Africa. Methods: Decision-analytic models were constructed using best available evidence sourced from unbundled data of an ongoing pilot trial assessing the effectiveness of high FiO2, published literature, and a cost survey in Nigeria, India, and South Africa. Effectiveness was measured as percentage of SSIs at 30 days after surgery, a healthcare perspective was adopted, and costs were reported in US dollars ($). Results: High FiO2 may be cost-effective (cheaper and effective). In Nigeria, the average cost for high FiO2 was $216 compared with $222 for low FiO2 leading to a −$6 (95% confidence interval [CI]: −$13 to −$1) difference in costs. In India, the average cost for high FiO2 was $184 compared with $195 for low FiO2 leading to a −$11 (95% CI: −$15 to −$6) difference in costs. In South Africa, the average cost for high FiO2 was $1164 compared with $1257 for low FiO2 leading to a −$93 (95% CI: −$132 to −$65) difference in costs. The high FiO2 arm had few SSIs, 7.33% compared with 8.38% for low FiO2, leading to a −1.05 (95% CI: −1.14 to −0.90) percentage point reduction in SSIs. Conclusion: High FiO2 could be cost-effective at preventing SSIs in the three countries but further data from large clinical trials are required to confirm this.

Abstract

Background: Early evidence suggested that the impact of the COVID-19 pandemic was less severe in Africa compared to other parts of the world. However, more recent studies indicate higher SARS-CoV-2 infection and COVID-19 mortality rates on the continent than previously documented. Research is needed to better understand SARS-CoV-2 infection and immunity in Africa. Methods: In early 2021, we studied the immune responses in healthcare workers (HCWs) at Lagos University Teaching Hospital (n = 134) and Oxford-AstraZeneca COVID-19 vaccine recipients from the general population (n = 116) across five local government areas (LGAs) in Lagos State, Nigeria. Western blots were used to simultaneously detect SARS-CoV-2 spike and nucleocapsid (N) antibodies (n = 250), and stimulation of peripheral blood mononuclear cells with N followed by an IFN-γ ELISA was used to examine T cell responses (n = 114). Results: Antibody data demonstrated high SARS-CoV-2 seroprevalence of 72·4% (97/134) in HCWs and 60·3% (70/116) in the general population. Antibodies directed to only SARS-CoV-2 N, suggesting pre-existing coronavirus immunity, were seen in 9·7% (13/134) of HCWs and 15·5% (18/116) of the general population. T cell responses against SARS-CoV-2 N (n = 114) were robust in detecting exposure to the virus, demonstrating 87·5% sensitivity and 92·9% specificity in a subset of control samples tested. T cell responses against SARS-CoV-2 N were also observed in 83.3% of individuals with N-only antibodies, further suggesting that prior non-SARS-CoV-2 coronavirus infection may provide cellular immunity to SARS-CoV-2. Conclusions: These results have important implications for understanding the paradoxically high SARS-CoV-2 infection with low mortality rate in Africa and supports the need to better understand the implications of SARS-CoV-2 cellular immunity.

Abstract

Background Men of African descent have the highest incidence and mortality rates of prostate cancer (PrCa) worldwide. Notably, PrCa is increasing in Africa with Nigerian men being mostly affected. Thus, it is important to understand risk factors for PrCa in Nigeria and build capacity for cancer research. The goals of this study were to determine the feasibility of conducting an epidemiological study of PrCa and to obtain preliminary data on risk factors for PrCa in Nigeria. Methods A case–control study (50 cases/50 controls) was conducted at the University College Hospital (UCH) in Ibadan, Nigeria, between October 2011 and December 2012. Men aged 40 to 80 years were approached for the study and asked to provide informed consent and complete the research protocol. Logistic regression models were used to examine associations between demographic, social and lifestyle characteristics and risk of PrCa. Results The participation rate among cases and controls was 98% and 93%, respectively. All participants completed a questionnaire and 99% (50 cases/49 controls) provided blood samples. Cases had a median serum diagnostic PSA of 73 ng/ml, and 38% had a Gleason score 8–10 tumor. Family history of PrCa was associated with a 4.9-fold increased risk of PrCa (95% CI 1.0 - 24.8). There were statistically significant inverse associations between PrCa and height, weight and waist circumference, but there was no association with body mass index (kg/m2). There were no associations between other socio-demographic and lifestyle characteristics and PrCa risk. Conclusion This feasibility study demonstrated the ability to ascertain and recruit participants at UCH and collect epidemiological, clinical and biospecimen data. Our results highlighted the advanced clinical characteristics of PrCa in Nigerian men, and that family history of PrCa and some anthropometric factors were associated with PrCa risk in this population. However, larger studies are needed to better understand the epidemiological risk factors of PrCa in Nigeria.

Abstract

Lung adenocarcinoma accounts for over 40% of lung cancer cases. There is still uncertainty in terms of prognosis, particularly because of limited pathological information among the predominant sub-patterns of adenocarcinomas. In this study, we evaluated the prognostic relationship with the predominant histological patterns in adenocarcinoma cases that underwent complete resection in one year. We retrospectively evaluated 100 patients with lung adenocarcinoma, whose pathological stage was determined after complete resection. Six patients were excluded from the study because of missing data in their files. The mortality rates and tumor stages of the patients were analyzed according to their histopathological subtypes with the predominant pattern. Seventy-four (79%) of the cases were male and 20 (21%) were female. The predominant pattern was solid in 41 (43.6%) patients, acinar in 31 (33%) patients, papillary in 10 (10.6%) patients, lepidic in 9 (9.6%) patients and micropapillary in 3 (3.2%) patients. Lymph node involvement was N0 in 30 (73.2%) patients, N1 in 9 (22%) patients and N2 in 2 (4.9%) patients in the solid group; N0 in 22 (71%) patients, N1 in 3 (9.7%) patients, and N2 in 6 (19.4%) patients in the acinar group. In the solid group, 23 (56.1%) patients survived, and 18 (14.6%) patients died, whereas 21 (67.7%) patients survived, and 10 (32.2%) patients died in the acinar group. The mean follow-up period of the patients was 32 months. In the mean follow-up of all patients, 58 (61.7%) survived and 36 (38.3%) died. No significant difference was observed between the subtypes in terms of mortality (p>0.05). N2 involvement was higher in acinar adenocarcinomas compared with the solid pattern, and the advanced stage due to the T factor was observed more in the solid pattern. Acinar-type adenocarcinoma shows similar prognostic characteristics to those with the solid pattern. [Med-Science 2022; 11(2.000): 581-5]

Abstract

Titanium aluminide alloys have gained attention for their lightweight and high-performance properties, particularly in aerospace and automotive applications. Traditional manufacturing methods such as casting and forging have limitations on part size and complexity, but additive manufacturing (AM), specifically electron beam melting (EBM), has overcome these challenges. However, the surface quality of AM parts is not ideal for sensitive applications, so post-processing techniques such as machining are used to improve it. The combination of AM and machining is seen as a promising solution. However, research on optimizing machining parameters and their impact on surface quality characteristics is lacking. Limited studies exist on additively manufactured TiAl alloys, necessitating further investigation into surface roughness during EBM TiAl machining and its relationship to cutting speed. As-built and heat-treated TiAl samples undergo machining at different feed rates and surface speeds. Profilometer analysis reveals worsened surface roughness in both heat-treated and non-heat-treated specimens at certain machining conditions, with higher speeds exacerbating edge cracks and material pull-outs. The hardness of the machined surfaces remains consistent within the range of 32–33.1 HRC at condition 3C (45 SFM and 0.1 mm/tooth). As-built hardness remains unchanged with increasing spindle and cutting head speeds. Conversely, heat-treated condition 3C surfaces demonstrate greater hardness than condition 1A (15 SFM, and 0.04 mm/tooth), indicating increased hardness with varying feed and surface speeds. This suggests crack formation in the as-built condition is considered to be influenced by factors beyond hardness, such as deformation-related grain refinement/strain hardening, while hardness and the existence of the α2 phase play a more significant role in heat-treated surfaces.

Abstract

Abstract Introduction Nigeria has a low uptake of cervical cancer screening and is one of the five countries that represent over half of the global burden of deaths from cervical cancer. Social marketing principles can be used to design and implement interventions to increase uptake of cervical cancer screening. This study assessed the effect of a social marketing intervention on the knowledge, attitude, and uptake of pap smear among women residing in an urban slum in Lagos State, Nigeria. Materials and methods This was a quasi-experimental study. The intervention arm consisted of 140 women recruited from Ago-Egun Bariga community and the control arm consisted of 175 women recruited from Oto-Ilogbo extension community. Social marketing intervention was instituted in the intervention group. Data analysis was done using IBM SPSS Statistics version 20 and Stata version 16.0. Between groups comparisons and within groups comparisons were done using bivariate analysis with Chisquare, Students t test and Paired t test as appropriate. Results In both the intervention and control groups, the mean knowledge score of cervical cancer was low at baseline (0.0 ± 0.3 and 0.1 ± 0.9 respectively). In the intervention group, there was a significant increase in mean knowledge score to 15.1 ± 3.7, post-intervention (p

Abstract

Abstract Population‐based drug utilization studies are scanty in Nigeria. The aim was to determine the pattern and predictors of medication use among adults in the communities of Southwestern Nigeria. A cross‐sectional study was conducted among adults selected by multi‐stage sampling from Oyo State communities. The questionnaires, adapted from the WHO Students' Drug Use Questionnaire and previous studies, were pretested and interviewer administered. The respondents' socio‐demographic characteristics, the pattern of medication use, prescribers, and sources of drug acquisition were obtained. Binary logistic regression was used to determine the predictor of medications used. Of the 999 respondents, 501 resided in rural communities while 498 dwelled in urban areas. The mean (±SD) age of the respondents was 38 ± 15 years. The median (range)% prevalence of medication use were as follows: lifetime use, 58.2 (17.7–81.0); current use, 31.2 (8.9–65.9); and past use, 20.3 (9.2–28.9). Medications were mainly obtained from patent medicine stores, median (range%), 71 (65–80). The commonly used drugs were paracetamol, 626 (67.6); nonsteroidal anti‐inflammatory drugs, 174 (18.8); artemether/lumefantrine, 422 (68.2); ampicillin/cloxacillin, 220 (48.6); and chlorpheniramine, 59 (39.9). Factors predictive of current medication use, adjusted odd ratio (95% confidence interval) were as follows: antimalarial [male, 0.7 (0.5, 0.9)]; antibacterial [male, 0.6 (0.4–0.9)]; analgesics [married, 1.5 (1.1–2.2); presence of health facilities, 0.5 (0.3–0.7); and shorter distance to health facility, 1.5 (1.1–2.1)]. Antimalarials, antibacterial, and analgesics were commonly used and inappropriately obtained by adults in Southwestern Nigeria. Factors predictive of current medication use were gender, marital status, the presence of health facilities, and distance to health facilities. There is a need for more extensive countrywide medication use studies and enlightenment programs to ensure the appropriate use of medications.
