RESUMEN

BACKGROUND: Traditional medicine in form of decoctions has been known for ages to possess wound healing abilities. One such traditional formulation mentioned in Indian literature Charak Samhita Chikitsa Sthanam is Kampillakadi Taila and tremendous information is available on its implication in the treatment of skin cuts and wounds, diseases, or bacterial infections. This research paper focuses on studying the wound healing property of one such herbal proprietary formulation known as a wound healing oil, derived from Kampillakadi Taila fortified with root extract of Wagatea spicata (VIKHPF). OBJECTIVE: The current research is aimed at studying chemical profiling, antioxidant activity, antimicrobial efficacy, in-vitro cell proliferating, and in-vitro wound healing activity of this VKHPF. MATERIALS AND METHODS: The chemical characterization of VKHPF was done by gas chromatography- fatty acid methyl esters GC-FAME analysis for lipid analysis and gas chromatography high-resolution mass spectrometry (GC-HRMS)for revealing its chemical constituents. Proliferation and migration are two underlying mechanisms involved in the healing of wounds. Hence, in-vitro studies such as cell proliferation assay and in-vitro scratch test on NIH/3T3 mice fibroblast cell line were conducted were used to determine in-vitro wound healing capacity of VKHPF. The oil was also tested for antioxidant effect (DPPH assay) and anti-microbial potential (Time kill test). RESULTS: The GC-HRMS and GC-FAME analyses revealed rich medicinally important fatty acids and vitamins were present in VKHPF, such as oleic acid, hexadecanoic acid, squalene, α, γ-tocopherol, γ-sitosterol, and benzoic acid. VKHPF at 0.5 mg/ml in media without serum showed 164.00 ± 0.011% cell viability with 64.00% cell proliferation in contrast to media containing serum (100% cell viability). At the same concentration, the wound closure was 98% for VKHPF. The oil sample possessed antioxidant activity with an IC50 value of 3.5 mg/ml and antimicrobial activity against Staphylococcus aureus and Pseudomonas aeruginosa when tested using Time Kill Activity. CONCLUSION: This study is the first to report the use of Vakeri fortified Kampillakadi Taila herbal proprietary formulation (VKHPF) in in-vitro wound healing and the present data suggest that it can form a part of modern medicine.

RESUMEN

The Supertowel is a fabric treated with a permanent antimicrobial bonding and has been designed as a soap alternative in emergency situations. The Supertowel has been shown to be as efficacious as handwashing with soap and water when tested under controlled laboratory conditions. It has also been shown to be a practical, acceptable, and desirable product among crisis-affected populations. The aim of this study was to test whether the Supertowel remains as efficacious when used under conditions which mimic real-world hand cleaning in challenging settings. Two rounds of laboratory tests, with 16 volunteers in each, were conducted to test the efficacy of the Supertowel when used for a shorter duration, when less wet, when used with contaminated water, when visibly dirty, and when dry. Volunteers pre-contaminated their hands with nonpathogenic Escherichia coli. Comparisons were made between hand cleaning with the Supertowel and the reference condition (normally handwashing with soap), using a crossover design. The Supertowel was marginally less efficacious than handwashing with soap when used for 15 seconds (P = 0.04) but as efficacious at 30 and 60 seconds durations. All the other Supertowel conditions were as efficient as their reference comparisons meaning that the Supertowel can effectively remove pathogens from hands when it is wet, damp, or completely dry, when it is used with contaminated water, when visibly dirty with mud and/or oil.

RESUMEN

Handwashing with soap reduces the transmission of diarrheal pathogens, but access to hand-washing facilities, water, and soap in humanitarian emergencies is limited. The SuperTowel® (ST) is a fabric treated with permanent antimicrobial bonding and has been designed as a soap alternative in emergency situations. The aim of this study was to test the efficacy of the ST as a hand-cleaning product. Two sets of laboratory tests, with 16 volunteers in each, were conducted to test the efficacy of different prototypes of the ST. Volunteers pre-contaminated their hands with nonpathogenic Escherichia coli. Comparisons were made between hand cleaning with the ST and handwashing with the reference soap, using a crossover design. Participants also completed a questionnaire about product perceptions. Three of the prototypes of the ST were more efficacious at removing E. coli from pre-contaminated hands than handwashing with soap (mean log10 reduction of 4.11 ± 0.47 for ST1, 3.84 ± 0.61 for ST2, and 3.71 ± 0.67 for ST3 versus 3.01 ± 0.63 for soap [P < 0.001, P = 0.002, and P = 0.005, respectively]). The ST prototypes used less water than handwashing with soap, were well accepted, and were considered preferable in communal settings. The ST has the potential to be a suitable complementary hand-cleaning product for humanitarian emergencies.

RESUMEN

OBJECTIVES: Vitamins and herbal extracts are associated with various side effects, potential serious drug interactions and mostly unproven efficacy. Yet, research has shown that nearly half of dementia patients are receiving such medication. Health professionals caring for older people with dementia are central to the safe management of this practice. Therefore, the aim of this study was to assess the views, knowledge and practices of professionals in relation to this issue. Such information is essential to identify potential problems and to inform targeted intervention strategies. METHOD: Cross-sectional survey carried out across East Sussex in the UK based on a self-administered postal questionnaire. RESULTS: Out of 350 questionnaires sent, 200 responded (57%). Health professionals greatly underestimated the prevalence of over-the-counter medication use (68% believed that less than 10% of patients receive such medication) when compared to published data. A considerable minority (38.7%) reported that vitamins and herbal extracts should be recommended for individuals at risk of developing dementia, despite lack of evidence to support such use. Further, only 24.4% always or often discussed potential side effects/interactions of these supplements with their patients. CONCLUSION: The views and practices of many health professionals are inconsistent with current best practice. Many professionals do not appear to enquire routinely about non-prescribed medicinal products and adequate advice may not be given to patients/carers. The data highlights a significant issue and calls for urgent action through targeted educational interventions directed not only at dementia patients and their carers, but at health professionals as well.
