Favourable Clinical and Functional Outcomes Following Total Knee Replacement Surgery in a Kenyan Hospital: A 6-Week Follow-Up Study
Authors: Vutiya Wycliffe , Matheri Joseph , Gachohi John 
Published: January 2025

Purpose: The incidence of total knee replacement (TKR) is increasing due to factors such as heightened patient satisfaction, an ageing population, and the obesity epidemic, all of which lead to more significant stress on weight-bearing joints. This study determined the incidence of prosthetic knee joint infection, evaluated functional recovery, and analysed rehabilitation progress among orthopaedic patients who underwent Total Knee Replacement in a hospital in Kenya.
Methodology: This study employed a prospective cohort study design for six months, following 75 patients who had undergone TKR at Metropolitan Hospital in Nairobi County. Data collection methods included medical record reviews, patient interviews, and clinical assessments. Specifically, standardized questionnaires and assessment tools were utilized, including the short form health survey (SF-12) for quality-of-life assessment, the visual analogue scale (VAS) for pain measurement, and relevant scales for activities of daily living (ADL) assessment. The incidence density of prosthetic joint infection was calculated using the conventional formula, accounting for new cases and patient time at risk. We observed that functional outcomes post-TKR are generally favourable, with patients who were followed up resuming their daily activities in a relatively short timeframe of less than six weeks.
Findings: By the sixth week, 60% of the patients had undergone excellent rehabilitation progress. The incidence of prosthetic knee infection was notably low (9 cases per 1000 patient weeks) and was only associated with age, perhaps highlighting the effectiveness of the applied surgical techniques and postoperative care. Additionally, we identified that comorbid conditions, particularly diabetes and hypertension, are the primary factors that contributed to delayed healing and resumption of daily activities following TKR.
Unique Contribution to Theory, Practice and Policy: Favourable outcomes and low infection rates indicate that total knee replacement (TKR) is a safe and effective option for patients with severe knee pain, significantly improving quality of life and mobility. However, the association between age and infection risk necessitates thorough preoperative assessments and age-specific care protocols, especially for older patients. Additionally, comorbidities like diabetes and hypertension can delay healing, highlighting the need for targeted preoperative interventions. Optimizing the management of these conditions may enhance recovery and reduce complications. Further research is essential to explore how these comorbidities affect healing post-TKR and to assess the effectiveness of specific interventions.

Published: January 2025

Since today’s customers not only purchase goods and services for their utilitarian but also hedonistic benefits, service recovery has become an integral part of any hotel that wishes to remain competitive. In a bid to remain competitive, most hotels have developed service systems. However, none of the systems in place are perfect. Though compensation has been proposed as a means of securing competitive advantage, scant evidence exist suggesting that the same can be used as recovery strategies to enhance customer experience. While using star rated hotels in Mombasa, Kenya, this study sought to adduce the effectiveness of compensation recovery strategies in enhancing customer experience using descriptive research design. Staff from10 front-line sections within the 17 rated hotels in Mombasa County formed the sampling frame. Data were collected by the use of an on-line questionnaire due to COVID-19 pandemic that prevailed during the study period. A pre-test of the questionnaire was done on one of the hotels, and the results were subjected to the Cronbach formula producing a reliability index of 0.989. Data were analysed by the use of inferential and descriptive statistics and the findings presented in tables, bar graphs and pie charts. From the findings, descriptive analysis on customer experience indicated that front line managers agreed and strongly agreed that when customers are pleased with their recovery effort, they receive referrals from them, they spend more money in the establishment, they show eagerness to return on, they become more loyal, they share with others about the good services, and they trust that any offer given to them in the future will go right. Descriptive analysis on the dimensions of the three strategies (compensation, staff actions, and communication strategies) produced high means and low standard deviations, indicating that front-line managers often and always applied the three recovery strategies whenever a failure occurred. The regression analysis of the three hypotheses indicated that the three strategies have a statistically significant influence on the customer experience if used effectively. Other than advancing scholarly work in the field of service recovery, the findings inform Kenya’s Ministry of Tourism and hotel stakeholders as a whole by guiding in policy review and formulation so as to help in minimizing service failures.

Currently, there exists great effort to ensure enhanced mainstreaming of persons living with disability (PWDs). Such efforts have surfaced despite a myriad of challenges. This study was founded on two objectives: follower characteristics as antecedents of LMX on organization performance in PWDs institutions and moderating effect of organization culture on follower-characteristics of LMX relationships and organization performance in PWDs institutions. The study was founded on two theories namely: Leader-Member exchange theory and Social Exchange theory. A conceptual framework presented the relationship between the variables of the study. Descriptive research design was used and the target population was lower level managers and subordinates at all levels within the organization. Stratified sampling of the various departments in the selected institutions were applied and random sampling and convenience sampling were used in the generation of the sample size. The study used a sample size of 39 and semi-structured questionnaires were used as data collection tool. A pilot study was conducted and applied Cronbach alpha reliability estimate. SPSS for windows version 21 was used to analyze data using descriptive statistics. Study results provided a reliable follower-characteristics framework of Leader-member relationships in organizations. One of the findings of the study was that followers possessed diverse characteristics that had a significant influence on leadership. Hence, the study concluded that focusing on follower-characteristics aids in availing new ideas on handling their work as well as interacting with their supervisors. In addition, followers are expected to ensure that they put their ego in control. The study recommends that followers are encouraged to consider fellow workers views to enhance creativity in problem solving. The study also recommends that followers be tasked with ensuring that they hold themselves to a high standard of personal success to achieve team goals.

Abstract: Access to safe and clean drinking water is essential but underground water contamination by some (heavy) metals poses a serious threat to water quality in many areas. This research focus was to analyze the concentration of various metals in underground water samples obtained from different locations in Malete, Kwara State, Nigeria. The metals of interest include lead (Pb), chromium (Cr), manganese (Mn), uranium (U), and cobalt (Co), which are associated with adverse health and environmental effects, such as cancer and other forms of diseases. Through atomic absorption spectrophotometry (AAS), the samples collected from Westend 1, Westend 2, Yidi road, New Yidi road, and School Road were analyzed to assess the concentration of some metals that can pose health risks. The results showed that the average lead (Pb) concentration across samples was 0.07 mg/L, chromium (Cr) was 0.02 mg/L, the average manganese (Mn) concentration was 0.16 mg/L, Uranium (U) averaged at 0.02 mg/L and Cobalt (Co) was found at an average concentration of 0.03 mg/L. The results were compared with the World Health Organization (WHO) drinking water quality standards. Chromium (Cr) concentration was below the WHO standard of 0.05 mg/L suggesting a low risk of chromium toxicity. while other metals were above the standard. Hence ,the results identified potential sources of metal contamination and represents a significant step toward addressing the environmental and health challenges posed by some metals contamination in Malete.
Heavy-tailed flood peak distributions: what is the effect of the spatial variability of rainfall and runoff generation?
Authors: Macdonald Elena , Merz Bruno , Nguyen Viet Dung , Vorogushyn Sergiy 
Published: January 2025

Abstract. The statistical distributions of observed flood peaks often show heavy-tailed behaviour, meaning that extreme floods are more likely to occur than for distributions with an exponentially receding tail. Falsely assuming light-tailed behaviour can lead to an underestimation of extreme floods. Robust estimation of the tail is often hindered due to the limited length of time series. Therefore, a better understanding of the processes controlling the tail behaviour is required. Here, we analyse how the spatial variability of rainfall and runoff generation affects the flood peak tail behaviour in catchments of various sizes. This is done using a model chain consisting of a stochastic weather generator, a conceptual rainfall-runoff model, and a river routing routine. For a large synthetic catchment, long time series of daily rainfall with varying tail behaviours and varying degrees of spatial variability are generated and used as input for the rainfall-runoff model. In this model, the spatial variability and mean depth of a sub-surface storage capacity are varied, affecting how locally or widely saturation excess runoff is triggered. Tail behaviour is characterized by the shape parameter of the generalized extreme value (GEV) distribution. Our analysis shows that smaller catchments tend to have heavier tails than larger catchments. For large catchments especially, the GEV shape parameter of flood peak distributions was found to decrease with increasing spatial rainfall variability. This is most likely linked to attenuating effects in large catchments. No clear effect of the spatial variability of the runoff generation on the tail behaviour was found.

Published: January 2025

Abstract. Water vapour flux, expressed as evapotranspiration (ET), is critical for understanding the earth climate system and the complex heat–water exchange mechanisms between the land surface and the atmosphere in the high-altitude Tibetan Plateau (TP) region. However, the performance of ET products over the TP has not been adequately assessed, and there is still considerable uncertainty in the magnitude and spatial variability in the water vapour released from the TP into the atmosphere. In this study, we evaluated 22 ET products in the TP against in situ observations and basin-scale water balance estimations. This study also evaluated the spatiotemporal variability of the total vapour flux and of its components to clarify the vapour flux magnitude and variability in the TP. The results showed that the remote sensing high-resolution global ET data from ETMonitor and PMLV2 had a high accuracy, with overall better accuracy than other global and regional ET data with fine spatial resolution (∼ 1 km), when comparing with in situ observations. When compared with water balance estimates of ET at the basin scale, ETMonitor and PMLV2 at finer spatial resolution and GLEAM and TerraClimate at coarse spatial resolution showed good agreement. Different products showed different patterns of spatiotemporal variability, with large differences in the central to western TP. The multi-year and multi-product mean ET in the TP was 333.1 mm yr−1, with a standard deviation of 38.3 mm yr−1. The ET components (i.e. plant transpiration, soil evaporation, canopy rainfall interception evaporation, open-water evaporation, and snow/ice sublimation) available from some products were also compared, and the contribution of these components to total ET varied considerably, even in cases where the total ET from different products was similar. Soil evaporation accounts for most of the total ET in the TP, followed by plant transpiration and canopy rainfall interception evaporation, while the contributions from open-water evaporation and snow/ice sublimation cannot be negligible.

Kekalahan ISIS (Negara Islam Irak dan Suriah) atas Pasukan Demokrat Suriah (SDF) yang didukung oleh Amerika Serikat menimbulkan sejumlah polemik, salah satunya terkait dengan pemulangan eks ISIS atau Foreign Terrorist Fighters (FTF). Perserikatan Bangsa-Bangsa (PBB) telah mengeluarkan official letters agar setiap negara memulangkan warga negaranya yang berada di kamp-kamp pengungsian Suriah. Namun, setiap negara merespon permasalahan ini dengan cara yang berbeda-beda pula. Menurut data, terdapat 553 orang WNI eks ISIS yang masih berada di tempat pengungsian yang diantaranya terdapat anak-anak. Pemerintah Indonesia saat ini hanya mempertimbangkan kesempatan untuk memulangkan anak-anak yatim piatu di bawah usia 10 tahun dan atas izin keluarga, Pertimbangan tersebut tentunya didasarkan atas adanya polemik di masyarakat terkait dengan isu pemulangan terhadap WNI eks ISIS atau FTF yang dikhawatirkan dapat menjadi permasalahan baru di masyarakat, yaitu penyebaran paham radikalisme. Artikel ini mengelaborasi permasalahan yang dihadapi dalam pelaksanaan upaya perlindungan terhadap anak korban tindak pidana FTF. Studi ini juga menjelaskan upaya perlindungan hukum oleh negara terhadap anak korban tindak pidana FTF. Terdapat banyak tantangan yang dihadapi oleh pemerintah Indonesia dalam upaya perlindungan hukum bagi anak korban tindak pidana FTF, sehingga diperlukan adanya perumusan kebijakan komprehensif melalui regulasi yang efektif.

Efficient water management is vital for sustainable maize production, particularly in water-stressed regions like Tehsil Okara, Pakistan, This study aims to determine the irrigation application efficiency of maize crops in Tehsil Okara by utilizing Environscan, Environscan probes was installed at multiple soil depths (15 cm, 30 cm, and 60 cm) to monitor real-time soil moisture dynamics throughout the maize growth cycle. Data were collected on soil moisture levels, irrigation volumes applied, and evapotranspiration rates to assess crop water requirements accurately. Application efficiency was calculated by evaluating the amount of water retained within the root zone relative to the total water applied. Field experiments were conducted under different irrigation methods, including flood, furrow, and drip irrigation, to compare their efficiency and effectiveness. The study also incorporated meteorological data, such as temperature, humidity, wind speed, and solar radiation, to estimate the crop's evapotranspiration rates and correlate them with soil moisture dynamics. Statistical tools, such as ANOVA, were used to analyze the differences in efficiency among the irrigation methods and their impact on maize yield. Economic analysis was also performed to evaluate the cost-benefit of integrating Environscan technology into irrigation practices. The findings of this research are expected to provide actionable insights into optimizing irrigation scheduling, conserving water resources, and improving maize productivity. The study aims to promote the adoption of precision irrigation technologies like Environscan among farmers. This work serves as a model for integrating advanced monitoring systems to achieve sustainable agriculture in water-scarce regions, contributing to enhanced water use efficiency, reduced resource wastage, and improved agricultural resilience to climate variability.

Sektor pertanian di Indonesia menghadapi tantangan karena berkurangnya lahan pertanian, Upaya yang dilakukan untuk mengatasi hal tersebut dengan menerapkan Hidroponik. Salah satu metode hidroponik adalah Metode NFT, yang telah diterapkan di Kebun Vefar Yogyakarta. Namun dalam penerapan Hidroponik dengan Metode NFT ini sering mengalami kendala berupa gagal panen yang disebabkan oleh sistem pemantauan nutrisi dan pH yang masih manual, belum dilakukan secara berkala, keterbatasan waktu dan tenaga dari pemilik serta karyawan, ditambah dengan luasnya lahan kebun hidroponik, menjadi faktor penghambat dalam pemantauan yang intensif. Pemantauan secara real-time terhadap nutrisi air dan pH air juga sangat penting untuk memaksimalkan hasil produksi. Untuk mengatasi masalah ini, diperlukan sistem pemantauan berbasis IoT yang memanfaatkan sensor pH dan TDS meter, Wemos D1 R32 sebagai mikrokontroler, dengan menggunakan Platform Antares dan Aplikasi Mobile apps MIT APP Inventor. Hasil menunjukkan prototype dapat memantau kondisi pH dan jumlah partikel padatan yang terlarut dalam air dengan pengujian selama satu hari dan keberhasilan seluruh hasil skenario pengujian. Nilai pH dan TDS pada larutan nutrisi menunjukkan fluktuasi yang relatif stabil dalam rentang waktu pengukuran. Nilai pH rata-rata berkisar antara 6.9 hingga 7.1, sedangkan nilai TDS berada di sekitar 1674-1828 ppm.

The agricultural sector in Indonesia is facing challenges due to the decreasing amount of agricultural land. Hydroponics has been implemented as a solution to address this issue. One method of hydroponics is the Nutrient Film Technique (NFT), which has been applied in Vefar Garden, Yogyakarta. However, the implementation of NFT hydroponics often encounters obstacles such as crop failures caused by manual nutrient and pH monitoring systems, which are not conducted regularly. Limited time and labor from owners and employees, coupled with the vast area of the hydroponic garden, hinder intensive monitoring. Real-time monitoring of water nutrients and pH is crucial for maximizing production. To overcome these problems, an IoT-based monitoring system was developed using pH and TDS sensors, a Wemos D1 R32 microcontroller, the Antares Platform, and the MIT App Inventor mobile app. The results show that the prototype can monitor pH conditions and the number of solid particles dissolved in water with testing for one day and the success of all test scenario.
