Abstract
BACKGROUND Breast cancer outcomes are poor in Nigeria, partly due to late-stage diagnosis. To assess the impact of past and present interventions, a review of an institutional data base was performed to determine the trend with respect to stage at diagnosis over a decade. METHODS A retrospective analysis of an institutional data base was performed over a decade. The review period was divided into segments (2013-2015, 2016-2018 and 2019-2022). The latter period (2019-2022), corresponds to a time of more intense community interventions aimed at promoting early diagnosis and treatment around the locality of the teaching hospital. The stage at diagnosis within these periods were compared. The relationship between stage and sociodemographic variables (age, religion, marital status, menopausal status, and level of education) was assessed. RESULTS There were 910 patients, 144 within the first period (2013-2015), 318 in the second (2016-2018) and 454 in the third period (2019-2022). The majority presented with stage 3 disease (73.8%). There was a significant decline in the proportion of metastatic cases and a concomitant increase in early cases in the latter part of the review. The proportion of metastatic cases reduced from 23.6% (2013-2015), to 15.7% (2016-2018) and 9.3% (2019-2022) (p=0.001). Level of education was significantly associated with stage (p=0.001). CONCLUSION This study shows a trend towards downstaging of breast cancer in our locality. This trend corresponds to the period of more intense community interventions, justifying the need to further interrogate the direct impact of each of the interventions. This will provide a firm basis for sustaining or improving on current efforts to achieve more robust gains.

Abstract
Abstract
Introduction
Trastuzumab(T) is a humanized monoclonal antibody used in the treatment of HER2-positive breast cancer and is available as a subcutaneous(sc) formulation thereby allowing short and convenient administration. A lack of trained nurses to administer T at home and/or train patients at home to self-administer, together with challenges in maintaining cold-chain delivery have impeded uptake of home administration.1,2 In order to support patients’ ability to self-administer T at home, we have implemented an educational programme that includes nurse-led training, education material, support apps and follow-up telephone clinics. Home delivery of pre-filled syringes was enabled in collaboration with commercial providers for aseptics and logistic.
Aim
The aim of this service evaluation was to evaluate the utility of this programme from the patients’ perspective and to assess patient satisfaction and impact on quality of life (QOL).
Methods
A previously validated Self-Injection Assessment Questionnaire (SIAQ)3 was modified to assess patient satisfaction, perceptions and impact of the programme. Patients who had agreed to enrol on the ‘self-administration’ scheme, were asked to complete the questionnaire at baseline, at the third training session and at the second self-administered dose. Approval from a Research Ethics Committee is not required for this service evaluation.
Results
All 14 patients offered the questionnaire responded to all questions. The median age was 58 years old (age range 43-76), 11 patients were Caucasian, 2 were Asian and one was African/Caribbean. The average distance from their home address to hospital was 10.1 miles (range 4-19). Following completion of the one-to-one nurse training there was an improvement in patient confidence to self-administer sc. T. No differences in ‘feeling in control of their treatment’ or ‘satisfaction of attending hospital appointments’ were noted. Of the 11 patients who reached the self-administration stage, 10 reported that they felt ‘very confident’ and 8 reported that it was ‘very easy’ to give themselves the injection. All patients rated themselves ‘very satisfied’ with self-administration and reported that the nurse training programme helped them to be more confident. 10 patients reported that the App and written information was useful as well as the pre- and post- administration telephone clinics. All patients reported that the self-administration programme had a positive impact on their QOL by reducing the number of hospital visits. In the first 4 months of self-administration each patient reduced their hospital attendance by an average of 8 appointments (median=8) equating to 10 hours of time that would have been spent at hospital.
Discussion/Conclusion
The subcutaneous T self-administration programme was well received by patients. The nurse training sessions and supportive materials enabled patients to feel more confident about self-administration with no reported incidents or adverse events. This led to fewer hospital visits and improved QOL. This programme was critically dependent on the services of a commercial compounder and homecare provider, emphasizing the importance of joint working between the NHS and commercial sector. Evaluation of this programme will continue and will include other agents, including Phesgo® (sc trastuzumab and pertuzumab) which have more patients and will improve the reliability of the results.

Abstract
BACKGROUND To examine the stages of delay in presentation and management of oral cancer patients at University College Hospital Ibadan and compare findings with previous studies. METHODS A 20-year retrospective analysis of the delay stages among oral cancer patients that utilized patient's biodata and clinical data. RESULT 169 oral cancer cases consisting of 127 carcinomas, 25 sarcomas and 17 lymphomas were analyzed. There was significant difference in the mean evolution time (ET) according to histological type (oral carcinoma = 282.8 +/- 414, oral sarcomas = 219.2 +/- 247.3 and oral lymphomas 105.5 +/- 115 days; p = 0.001). Patient's delay was more than professional delay for all cancer types (65.9%, 59.1% and 60.1% for carcinomas, sarcomas and lymphomas respectively). There was a significant difference in the mean ET of the early stage cancers compared with the late stage cancers (mean = 137.2 +/- 99 and 266.4 +/- 355; p = 0.010). CONCLUSION A combination of patients and professional delay negatively influenced the management of oral cancer patients but the patient's delay formed the bulk of this combination in our center.

Abstract
The malaria parasite, Plasmodium falciparum, spends part of its life cycle inside the enucleated erythrocytes of its human host. The parasite modifies the cytoplasm and plasma membrane of its host cell by exporting proteins beyond the confines of its own plasma membrane. We have previously provided evidence that a plasmodial homologue of the COPII protein, Sar1p, is involved in the trafficking of proteins across the erythrocyte cytoplasm. We have now characterised an additional plasmodial COPII protein homologue, namely Sec31p. Recombinant proteins corresponding to the WD-40 and the intervening domains of the PfSec31p sequence were used to raise antibodies. The affinity-purified antisera recognised a protein with an apparent relative molecular mass of 1.6×105 on western blots of malaria parasite-infected erythrocytes but not on blots of uninfected erythrocytes. PfSec31p was shown to be largely insoluble in nonionic detergent, suggesting cytoskeletal attachment. Confocal immunofluorescence microscopy of malaria parasite-infected erythrocytes was used to show that PfSec31p is partly located within the parasite and partly exported to structures outside the parasite in the erythrocyte cytoplasm. We have also shown that PfSec31p and PfSar1p occupy overlapping locations. Furthermore, the location of PfSec31p overlaps that of the cytoadherence-mediating protein PfEMP1. These data support the suggestion that the malaria parasite establishes a vesicle-mediated trafficking pathway outside the boundaries of its own plasma membrane – a novel paradigm in eukaryotic biology.

Abstract
Thirteen fungi including toxigenic Aspergillus nidulans and A. clavatus were isolated from the grains. The isolated fungi grew well at 25-30 degrees C. A. clavatus and A. nidulans were grown in liquid maize yeast extract medium and wheat yeast extract medium. Both fungi produced amylases on the two media and on the basal medium at 30 degrees C. During incubation more total reducing sugars were detected in maize grains than in wheat while non-reducing sugars were detected than reducing sugars in both grains. A. clavatus showed highest amylase activities at 25-30 degrees C and at a pH 7-8 while 30 degrees C and pH 6.0 were the optimum conditions for highest amylase activities of A. nidulans. During incubation with both fungi a decrease in the protein and carbohydrate contents of both grains was recorded while more fat was accumulated in the grains.
