- Abstract
An open fracture is when the fractured part of a bone is exposed to the external environment by breaching the overlying soft tissue and skin. Open fractures often arise from high-energy injuries, and the risk of microbial contamination is high. There is a need to understand the management of open fractures in Africa by assessing the overall prevalence of open fractures, the mechanisms of injury, management approaches and outcomes. A literature search was conducted using PubMed, African Journal Online, and Google Scholar regarding open fracture management in Africa from inception till date. Thirty-nine (39) studies were included in this review. Road traffic accidents represented the majority of all mechanisms of open fractures, with the Tibia being the most affected bone. 320 cases were classified as Gustilo Anderson Type 1, with 487 classified as Type 2. Type 3 was divided into 3A (330), 3B (248), and 3C (34). Most studies recorded the immediate administration of intravenous antibiotics, but tetanus prophylaxis was only given in 13 studies, while initial debridement and washout were done in 35 studies. External fixators and Kirschner wires were most used for initial fixation. Follow-up for patients was between six weeks to 50 months. There were 645 cases of malunion, 83 cases of non-union, and 88 patients who had delayed union. There were 147 cases of wound infection and 119 cases of pin tract infections. Our findings emphasize the need for standardized protocols and robust emergency services to manage open fractures within Africa., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

- Abstract
Background: Spinal tuberculosis (STB) is a significant contributor to nontraumatic myelopathy. There is a rising burden in Africa, in parallel with the high prevalence of human immunodeficiency virus. We conducted a scoping review to highlight the disparities in the management and outcomes of STB in Africa., Methods: This study was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping review guidelines. AJOL, Embase, MEDLINE, Google Scholar, and Cochrane CENTRAL databases were searched to identify all relevant peer-reviewed articles published on the management of STB in African centers, excluding abstract-only articles, literature reviews, and meta-analyses., Results: Sixty studies were eligible for inclusion, comprising data from 3416 patients aged 8 months to 89 years (median, 32 years). Thoracic and lumbar segments were the most commonly affected vertebral regions (thoracic = 42.7%; lumbar = 35.9%). The most common clinical features were back pain and neurological deficits. Lack of essential laboratory and imaging diagnostic infrastructure was a common problem. Patients received antitubercular therapy (ATT) for varying durations, and only 18.3% underwent surgery. A favorable outcome was achieved in 51.6% of patients, 20.3% developed a permanent disability, and the mortality rate was 2.1%. Treatment outcome was adversely affected by a high rate of late presentation and treatment default., Conclusions: ATT remains the mainstay of treatment; however, the duration of treatment varied widely among studies. Further research is required to explore the feasibility and efficacy of short-course ATT in treating STB in the African population., (Copyright © 2024 Elsevier Inc. All rights reserved.)

- Abstract
Background: Yam (Dioscorea alata L.) is the staple food of many populations in the intertropical zone, where it is grown. The lack of phenotyping methods for tuber quality has hindered the adoption of new genotypes from breeding programs. Recently, near-infrared spectroscopy (NIRS) has been used as a reliable tool to characterize the chemical composition of the yam tuber. However, it failed to predict the amylose content, although this trait is strongly involved in the quality of the product., Results: This study used NIRS to predict the amylose content from 186 yam flour samples. Two calibration methods were developed and validated on an independent dataset: partial least squares (PLS) and convolutional neural networks (CNN). To evaluate final model performances, the coefficient of determination (R
2 ), the root mean square error (RMSE), and the ratio of performance to deviation (RPD) were calculated using predictions on an independent validation dataset. The tested models showed contrasting performances (i.e., R2 of 0.72 and 0.89, RMSE of 1.33 and 0.81, RPD of 2.13 and 3.49 respectively, for the PLS and the CNN model)., Conclusion: According to the quality standard for NIRS model prediction used in food science, the PLS method proved unsuccessful (RPD < 3 and R2 < 0.8) for predicting amylose content from yam flour but the CNN model proved to be reliable and efficient method. With the application of deep learning methods, this study established the proof of concept that amylose content, a key driver of yam textural quality and acceptance, can be predicted accurately using NIRS as a high throughput phenotyping method. © 2023 The Authors.

- Abstract
Background: Cassava utilization for food and/or industrial products depends on inherent properties of root dry matter content (DMC) and the starch fraction of amylose content (AC). Accordingly, in the present study, near-infrared reflectance spectroscopy (NIRS) models were developed to aid breeding and selection of DMC and AC as critical industrial traits taking care of root sample preparation and cassava germplasm diversity available in Uganda., Results: Upon undertaking calibrations and cross-validations, best models were adopted for validation. DMC in calibration samples ranged from 20 to 45 g 100g
-1 , whereas, for amylose content, it ranged from 14 to 33 g 100g-1 . In the validation set, average DMC was 29.5 g 100g-1 , whereas, for amylose content, it was 24.64 g 100g-1 . For DMC, a modified partial least square regression model had regression coefficients (R2 ) of 0.98 and 0.96, respectively, in the calibration and validation set. These were also associated with low bias (-0.018) and ratio of performance deviation that ranged from 4.7 to 5.0. In addition, standard error of prediction values ranged from 0.9 g 100g-1 to 1.06 g 100g-1 . For AC, the regression coefficient was 0.91 for the calibration set and 0.94 for the validation set. A bias equivalent to -0.03 and a ratio of performance deviation of 4.23 were observed., Conclusion: These findings confirm the robustness of NIRS in the estimation of dry matter content and amylose content in cassava roots and thus justify its use in routine cassava breeding operations. © 2023 The Authors.

- Abstract
Background: Assessment of the key preferred quality traits in pounded yam, a popularly consumed yam food product in West Africa, is often done through sensory evaluation. Such assessment is time-consuming and results may be biased. Therefore, there is a need to develop objective, high-throughput methods to predict the quality of consumer-preferred traits in pounded yam. This study focused on how key quality traits in pounded yam proposed to yam breeders were determined, measured by biophysical and biochemical methods, in order to shorten the breeding selection cycle through adoption of these methods by breeders., Results: Consumer tests and sensory quantitative descriptive analysis (QDA) validated that preferred priority quality traits in pounded yam were related to textural quality (smooth, stretchable, moldable, slightly sticky and moderately hard) and color (white, cream or light yellow). There were significant correlations between sensory textural quality attributes cohesiveness/moldability, hardness, and adhesiveness/stickiness, with textural quality measurements from instrumental texture profile analysis (TPA). Color measurement parameters (L*, a*, and b*) with chromameter agreed with that of sensory evaluation and can replace the sensory panel approach. The smoothness (R
2 = 1.00), stickiness (R2 = 1.00), stretchability (R2 = 1.00), hardness (R2 = 0.99), and moldability (R2 = 0.53) of pounded yam samples can be predicted by the starch, amylose, and protein contents of yam tubers estimated by near-infrared spectroscopy., Conclusion: TPA and Hunter colorimeter can be used as medium-high throughput methods to evaluate the textural quality and color of pounded yam in place of the sensory panelists. © 2023 The Authors.

- Abstract
Roots, tubers and bananas (RTBs) contribute immensely to food security and livelihoods in sub-Saharan Africa, Asia and Latin America. The adoption of RTB genotypes in these regions relies on the interplay among agronomic traits, ease of processing and consumer preference. In breeding RTBs, until recently little attention was accorded key textural traits preferred by consumers. Moreover, a lack of standard, discriminant, repeatable protocols that can be used to measure the textural traits deter linkages between breeding better RTB genotypes and end user/consumer preferences. RTB products texture - that is, behaviour of RTB food products under unique deformations, such as disintegration and the flow of a food under force - is a critical component of these preferences. The preferences consumers have for certain product texture can be evaluated from expert sensory panel and consumer surveys, which are useful tools in setting thresholds for textural traits, and inform breeders on what to improve in the quality of RTBs. Textural characterization of RTBs under standard operating procedures (SOPs) is important in ensuring the standardization of texture measurement conditions, predictability of textural quality of RTBs, and ultimately definition of RTB food product profiles. This paper reviews current SOPs for the textural characterization of RTBs, including their various associated methods, parameters, challenges and merits. Case studies of texture characterized during development of SOPs and evaluation of texture of RTB populations are discussed, together with insights into key textural attributes and correlations between instrumental, sensory and consumer assessment of texture unique to various RTB food products. Hardness was considered a universal key textural attribute to discriminate RTBs. The review should provide adequate insight into texture of RTB food products and critical factors in their measurement. It aims to promote inclusion of texture in breeding pipelines by investigating which textural traits are prioritized by consumers, particularly since the inclusion of textural traits has recently gained prominence by breeders in improving RTBs. © 2023 The Authors.

- Abstract
Introduction: The biofortification of staple foods such as cassava is one of the technological breakthroughs in the nutritional improvement of foods. Fufu is one of the fermented cassava products produced and consumed in major West African countries, including Sierra Leone, and the majority of the processes involved in its production have direct and indirect effects on its properties. This study looked at how the concentration and retention of micronutrients in yellow-fleshed cassava fufu varied depending on genotype and processing method., Methods: Six yellow-fleshed cassava root genotypes (TMS-070557, TMS-011371, TMS-011412, TMS-011663, TMS-083724, TMS-083774) and one white (TME 419 as a control) were processed into fufu using both conventional (oven and sun-dried) and traditional (bowl and river) methods. The Statistical Analysis System (SAS) version 9.4 was used to analyze data using means, percentages, analysis of variance and means separated by least significant differences (LSD)., Results and Discussion: In the modified traditional river method, raw and cooked fufu samples had significantly higher β-carotene concentrations and true retention (TR) percentages (11.06 g/g (46.77%) and 4.54 g/g (16.94%), respectively) than other genotypes (p < 0.0001). Modified traditional fufu processing methods increased total β-carotene concentrations, while raw roots showed a significant decrease in total carotenoid and β-carotene concentrations, regardless of genotype or processing method. Sun-drying was the most effective method, with significantly higher concentrations and TR percentages of iron (10.01 mg/kg, 18.02%) and zinc (11.49 mg/kg, 40.64%) in raw and cooked fufu samples. Genotype TMS-083724 outperformed both conventional fufu processing methods, displaying a significant total carotenoid concentration and true retention percentage. Finally, this study found that the concentrations and percentages of TR of micronutrients varied depending on the processing method and genotype. It is recommended that a modified traditional river fufu processing method be further developed and improved in order to maximize provitamin A carotenoids, concentrations, and percentage TR., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

- Abstract
Background Infection in orthopedic surgery is one of the most dreaded complications. It is associated with prolonged morbidity, disability, and increased mortality. One of the cornerstones of the prevention of infections is antibiotic prophylaxis. This study assessed the practice of antibiotic prophylaxis in arthroplasty surgeries in our local hospital. Methods One hundred and seventy-one elective joint replacement patients were retrospectively analyzed for documentation of antibiotic plan in postoperative instruction, choice of antibiotic, dose, and dosage. Compliance with the dosage (duration and frequency) of antibiotic prophylaxis was compared among patients who underwent different operations, among patients whose operation notes had antibiotics plans, and among those patients whose operation notes lacked this information. Results Ninety-six females and 75 males with a mean age of 71.4±9.8 years who underwent hip replacement, knee replacement, or shoulder replacement were included in this study. Preoperative and postoperative antibiotics were received by 100% and 94.7% of patients, respectively. In 19.3%, there was no instruction about postoperative antibiotics while 4% missed at least one postoperative dose. The dosage of postoperative prophylactic antibiotics was variable as 26.3% of the patients experienced delayed administration of doses. Not having intravenous access, failure to prescribe antibiotics, and prescribing antibiotics in the "once only" rather than "regular medication" section of the medication chart were the reasons for improper timing of antibiotic doses. Observing surgical safety checklist was effective in ensuring preoperative antibiotic administration, whereas failing to document antibiotic plan in operation note was associated with poor compliance with postoperative dosage. Interprofessional participation is crucial to compliance with antibiotic prophylaxis practice. Conclusion This study identified key areas for improvement in our antibiotics prophylaxis practice. It resulted in implementing strategies to improve staff's awareness about the importance of timely administration of prophylactic antibiotics and proper documentation by all team members., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Oladeji et al.)

- Abstract
This study aimed to assess the antioxidant, enzyme inhibitory, physicochemical and sensory properties of instant bio-yoghurts containing multi-purpose natural additives. Multi-purpose natural additives were formulated with three natural additives (sweet detar seed, ginger rhizome, and hibiscus calyx flours, as a thickener, flavourant and colourant, respectively) blends at proportions derived from the Design Expert. The additives' synthetic counterparts were formulated with sodium carboxymethylcellulose, vanilla flavor, and red colourant at the same proportions. After that, yoghurt was produced and the additives blends were incorporated into it either in aqueous extract or flour form, yielding bio-yoghurts designated multi-purpose natural additive extract-containing yoghurt (MNAE-yoghurt), multi-purpose natural additive flour-added yoghurt (MNAF-yoghurt), and their multi-purpose synthetic additives-containing counterparts (MSAE-yoghurt and MSAF-yoghurt). A commercially-available bio-yoghurt served as a control. All the yoghurts were lyophilized to obtain instant bio-yoghurts. Subsequently, bioactive components (total phenolics, tannins, total flavonoids and saponins), antioxidants and enzymes [alpha-amylase, alpha-glucosidase, pancreatic lipase, and angiotensin 1-converting enzyme (ACE)] inhibitory activities, as well as proximate, physicochemical and sensory qualities of the bio-yoghurts were determined. The MNAE-yoghurt and MNAF-yoghurt had higher bioactive constituents, total titratable acid levels, and more potent antioxidant and enzyme inhibitory properties, but a lower pH than their synthetic counterparts and the control. The total phenolics, tannins, total flavonoids and saponins levels of MNAE-yoghurt and MNAF-yoghurt were 14.40 ± 0.24 and 16.54 ± 0.62 mg/g, 1.65 ± 0.04 and 1.74 ± 0.08 mg/g, 4.25 ± 0.03 and 4.40 ± 0.02 mg/g, 0.64 ± 0.01 and 0.66 ± 0.02 mg/g, respectively. Among the natural multi-purpose additives-containing bio-yoghurts, MNAF-yoghurt had higher bioactive constituents and stronger antioxidant and enzymes inhibitory properties. Its α-amylase, α-glucosidase, ACE, and pancreatic lipase IC
50 values were 72.47 ± 0.47, 74.07 ± 0.02, 25.58 ± 2.58, and 33.56 ± 29.66 μg/mL, respectively. In contrast, MNAE-yoghurt had the highest protein (13.70 ± 0.85%) and the lowest fat (2.63 ± 0.71%) contents. The sensory attributes of all the bio-yoghurts fell within an acceptable likeness range. Overall, the inclusion of multi-purpose natural additives blends enhanced the instant bio-yoghurts' nutritional, health-promoting, and sensory qualities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
