RESUMO

Blood Culture and Drug Susceptibility Testing (CDST) remains vital for the diagnosis and management of bloodstream infections (BSIs). While the Ghana National Standard Treatment Guidelines require CDST to be performed in each case of suspected or clinically diagnosed BSI, these are poorly adhered to in the Ho Teaching Hospital (HTH). This study used secondary medical and laboratory records to describe blood CDST requests by clinicians and the quality of CDST processes for the diagnosis of BSI among patients admitted to HTH from 2019 to 2021. Of 4278 patients, 33% were infants. Pneumonia and neonatal sepsis cases were 40% and 22%, respectively. Only 8% (351/4278) had blood CDST requested. Of 94% (329/351) blood CDST processed and reported, only 7% (22/329) were culture-positive, with likely contaminants being recovered from 16% (52/329) of the specimens. The duration from admission to request was 2 days (IQR: 0-5), and Further qualitative studies must be conducted to understand the reasons for low blood CDST utilisation among clinicians and the patient outcomes. Targeted interventions are required to enhance the utilisation of blood CDST by clinicians and the quality of laboratory processes.

RESUMO

Reusing agro-industrial waste does not only help to mitigate environmental impact but also enables valorization through the development of new products. The aim is to enhance the physical and mechanical properties of particleboard panels produced with Eucalyptus wood and different proportions of waste products-coconut fiber (Cocos nucifera L.). Physical properties (density, water absorption, and thickness swelling) and mechanical properties (static bending and internal bond resistance) were assessed, and panels reinforced with coconut fiber showed the best qualities with higher density, greater dimensional stability, and less water absorption. Static bending resistance and internal bond resistance also increased significantly. This demonstrated the potential of achieving compatible characteristics for civil construction and furniture production through the inclusion of waste material. The impact of this research is obtained from the utilization of an important agro-industrial residue in the manufacture of permanent composites.

RESUMO

BACKGROUND: Candida is the leading cause of vaginitis, and 75% of women have at least one episode of infection in their lives, with pregnancy being a predisposing factor. If left untreated, vulvovaginal candidiasis (VVC) can lead to chorioamnionitis with subsequent abortion, prematurity and congenital infection of the neonate. We aimed to determine the prevalence of VVC, identify the recent and most frequently occurring species of Candida in pregnant women, and determine the most effective antifungal drug of choice for treatment. METHOD: A prospective cross-sectional study in which 176 high vaginal swab samples of consented pregnant women visiting the antenatal clinic from February 2018 to April 2018 were subjected to direct gram smear and culture for Candida isolation. Candida isolates were identified using a germ tube test and HiCrome Candida differential agar. Candida isolates were then subjected to a disk diffusion method using fluconazole (25 µg), nystatin (100 units), and voriconazole (1 µg) on Mueller-Hinton agar supplemented with 2% (w/v) glucose and 0.5 µg/ml methylene blue dye to determine the susceptibility pattern as per the guidelines of the Clinical Laboratory Standard Institute (CLSI). Chi-square analysis was used to ascertain the significant association of participants' sociodemographics and clinical presentations to VVC. A univariate logistic regression model was used to identify potential risk factors of VVC. RESULTS: The prevalence of VVC among our study participants was 30.7%. Non-albicans Candida (NAC) and Candida albicans had a prevalence of 74.1 and 25.9%, respectively. Candida glabrata was the most common species, followed by Candida albicans, Candida krusei, and Candida parapsilosis. 50.0, 18.5 and 3.7% of Candida species were susceptible to voriconazole, fluconazole and nystatin, respectively, whereas 37.0, 48.1 and 9.3% of Candida species were resistant to voriconazole, fluconazole and nystatin, respectively. The majority of isolates were susceptible dose dependent to all three antifungal agents, with voriconazole being the most efficacious antifungal agent. There was no significant association between participants' socio-demographic information and clinical presentations to VVC. CONCLUSION: The prevalence of VVC was high in the study area. C. glabrata was found to be the most common cause of VVC among the pregnant women attending antenatal clinics, in the Ho Municipality region of Ghana. The majority of the Candida isolates were susceptible and resistant to voriconazole and fluconazole, respectively.
