Influence of Management of Government Records to The Promotion of Good Governance in Two Ministries of Katsina State
This paper examines ‘the influence of management of government records to the promotion of good governance in two ministries of Katsina State’. Two research objectives were stated : to find out the type of policy used in the management of records and to find out the influence of management of records to the promotion of good governance in Katsina State; the literature were reviewed based on the research questions, the method used in this study was survey and the population of the study is 55 which comprised records managers, staff officers, secretaries among others, the findings of this study indicated that there is no records management policy in the ministries and the area in which records influence governance are for effective administration, decision making and accountability, recommendations were provided such as; awareness campaign through seminars and workshops should be provided to the staff of the offices and records management policy should be made available and implemented for the efficiency and effectiveness of management of records in the ministries
Prevalence of undernutrition and risk factors of severe undernutrition among children admitted to Bugando Medical Centre in Mwanza, Tanzania
BACKGROUND: Malnutrition is a major public health problem in developing countries including Tanzania, contributing up to 50 % of under-five mortality. East Africa region was among the three United Nations (UN) subregions with the highest prevalence of stunting in 2011. In resource limited countries, the available little resources in hospitals are likely to be used focusing the primary clinical problem that led to admission of children leaving moderate and mild malnutrion unattended. This work was conducted to determine the prevalence of under-nutrition and risk factors associated with severe malnutrition among undernourished children aged 6–60 months admitted to Bugando Medical Centre (BMC) paediatric wards. METHOD: This was a hospital-based cross sectional study where by 720 children were screened in order to determine their nutritional status. Data were collected through measurement of weight/length or height, mid upper arm circumference (MUAC) and interpretation was done using Z-score (mild malnutrition ≤1SD, moderate malnutrition ≤2SD and severe malnutrition ≤3SD). The socio-demographic data were obtained using a questionnaire that was completed by interviewing children’s parents/caregiver. RESULTS: Out of 720 screened children, 402 (55.8 %) were undernourished. Severe malnutrition was found in 178 (24.7 %) children and among these 97 (54.5 %) had marasmus. Risk factors associated with severe malnutrition were children with age less than 2 years, lack of vaccination, taking unbalanced diet, low maternal education and single parent, with p-value (<0.001, < 0.001, <0.001, 0.02, < 0.001) respectively. CONCLUSION: This study show a high prevalence of malnutrition in hospitalized children and the majority was marasmic. The risk factors associated with severe malnutrition were described. We recommend improving the screening for undernutrition in all admitted patients so that proper management of this problem can be done concurrently with the primary clinical disease that led to admission
Green Synthesized Silver Nanoparticles Using Tridax Procumbens for Topical Application: Excision Wound Model and Histopathological Studies
The objective of this study was to synthesize silver nanoparticles from the leaves of Tridax procumbens and develop its topical gels using chitosan to investigate the wound healing efficacy concomitant with the histopathological study. Green synthesized silver nanoparticles (AgNPs) were prepared by reacting silver nitrate (0.3 M) with leaf extract and characterized by particle analysis, FTIR, XRD, SEM, BET, and TGA. The results revealed formed AgNPs were nano-sized (138 ± 2.1 nm), monodispersed (PDI: 0.460 ± 0.3), inter-particle repulsion (zeta: −20.4 ± 5.20 mV), stabilized, crystalline and, spherical with size ranging from 80–100 nm as per SEM micro photos. The BET analysis of AgNPs presents the surface area (12.861 m2/g), pore volume (0.037 cc/g), and pore radius (24.50 nm).TGA results show a loss of 13.39% up to 300 °C. The topical formulation was developed by loading AgNPs in chitosan-based gels, evaluated by pH, thermal cycling, centrifugal, and spreadability tests. AgNPs chitosan gels results showed skin compatibility, higher stability, and spreading ability. The maximum antibacterial zone of inhibition was found to be 25 ± 0.98 mm for bacillus subtitles and 30 ± 1.99 mm for Klebsiella pneumoniae, respectively. Nanosilver-containing gel also showed excellent compatibility with erythrocytes. Excision wound model was used to assess the wound healing property of the developed AgNP gels, the results of which indicated a significantly progressive healing process in test-group of animals treated with chitosan-based gels containing AgNPs. A histopathological study further confirmed the almost normal skin structure of treated animal tissue compared to standard and negative control. Thus, green synthesized AgNPs loaded chitosan-based topical gel can potentially be used for wound healing application
Trends of Plasmodium falciparum molecular markers associated with resistance to artemisinins and reduced susceptibility to lumefantrine in Mainland Tanzania from 2016 to 2021
Abstract Background Therapeutic efficacy studies (TESs) and detection of molecular markers of drug resistance are recommended by the World Health Organization (WHO) to monitor the efficacy of artemisinin-based combination therapy (ACT). This study assessed the trends of molecular markers of artemisinin resistance and/or reduced susceptibility to lumefantrine using samples collected in TES conducted in Mainland Tanzania from 2016 to 2021. Methods A total of 2,015 samples were collected during TES of artemether-lumefantrine at eight sentinel sites (in Kigoma, Mbeya, Morogoro, Mtwara, Mwanza, Pwani, Tabora, and Tanga regions) between 2016 and 2021. Photo-induced electron transfer polymerase chain reaction (PET-PCR) was used to confirm presence of malaria parasites before capillary sequencing, which targeted two genes: Plasmodium falciparum kelch 13 propeller domain (k13) and P. falciparum multidrug resistance 1 (pfmdr1). Results Sequencing success was ≥ 87.8%, and 1,724/1,769 (97.5%) k13 wild-type samples were detected. Thirty-seven (2.1%) samples had synonymous mutations and only eight (0.4%) had non-synonymous mutations in the k13 gene; seven of these were not validated by the WHO as molecular markers of resistance. One sample from Morogoro in 2020 had a k13 R622I mutation, which is a validated marker of artemisinin partial resistance. For pfmdr1, all except two samples carried N86 (wild-type), while mutations at Y184F increased from 33.9% in 2016 to about 60.5% in 2021, and only four samples (0.2%) had D1246Y mutations. pfmdr1 haplotypes were reported in 1,711 samples, with 985 (57.6%) NYD, 720 (42.1%) NFD, and six (0.4%) carrying minor haplotypes (three with NYY, 0.2%; YFD in two, 0.1%; and NFY in one sample, 0.1%). Between 2016 and 2021, NYD decreased from 66.1% to 45.2%, while NFD increased from 38.5% to 54.7%. Conclusion This is the first report of the R622I (k13 validated mutation) in Tanzania. N86 and D1246 were nearly fixed, while increases in Y184F mutations and NFD haplotype were observed between 2016 and 2021. Despite the reports of artemisinin partial resistance in Rwanda and Uganda, this study did not report any other validated mutations in these study sites in Tanzania apart from R622I suggesting that intensified surveillance is urgently needed to monitor trends of drug resistance markers and their impact on the performance of ACT
A Systematic Review and Meta-Analysis of Fecal Contamination and Inadequate Treatment of Packaged Water
<div><p>Background</p><p>Packaged water products provide an increasingly important source of water for consumption. However, recent studies raise concerns over their safety.</p><p>Objectives</p><p>To assess the microbial safety of packaged water, examine differences between regions, country incomes, packaged water types, and compare packaged water with other water sources.</p><p>Methods</p><p>We performed a systematic review and meta-analysis. Articles published in English, French, Portuguese, Spanish and Turkish, with no date restrictions were identified from online databases and two previous reviews. Studies published before April 2014 that assessed packaged water for the presence of <i>Escherichia coli</i>, thermotolerant or total coliforms were included provided they tested at least ten samples or brands.</p><p>Results</p><p>A total of 170 studies were included in the review. The majority of studies did not detect fecal indicator bacteria in packaged water (78/141). Compared to packaged water from upper-middle and high-income countries, packaged water from low and lower-middle-income countries was 4.6 (95% CI: 2.6–8.1) and 13.6 (95% CI: 6.9–26.7) times more likely to contain fecal indicator bacteria and total coliforms, respectively. Compared to all other packaged water types, water from small bottles was less likely to be contaminated with fecal indicator bacteria (OR = 0.32, 95%CI: 0.17–0.58) and total coliforms (OR = 0.10, 95%CI: 0.05, 0.22). Packaged water was less likely to contain fecal indicator bacteria (OR = 0.35, 95%CI: 0.20, 0.62) compared to other water sources used for consumption.</p><p>Conclusions</p><p>Policymakers and regulators should recognize the potential benefits of packaged water in providing safer water for consumption at and away from home, especially for those who are otherwise unlikely to gain access to a reliable, safe water supply in the near future. To improve the quality of packaged water products they should be integrated into regulatory and monitoring frameworks.</p></div
