We recently reported a new ultrasound-based fabrication technology that exploits the ability of ultrasound to generate localized mechanical forces and thermal effects to control collagen fiber microstructure non-invasively. Exposing solutions of type I collagen to ultrasound during the period of microfibril assembly produced changes in collagen fiber structure and alignment, and increased the biological activity of the resultant collagen hydrogels. In the extracellular matrix, interactions between fibronectin and collagen fibrils influence the biological activity of both proteins. Thus, in the present study, we examined how addition of fibronectin to collagen solutions prior to ultrasound exposure affects protein organization and the biological activity of the composite hydrogels. Results indicate that ultrasound can alter the distribution of fibronectin within 3D hydrogels via thermal and non-thermal mechanisms to produce composite hydrogels that support accelerated microtissue formation. The use of acoustic energy to drive changes in protein conformation to functionalize biomaterials has much potential as a unique, non-invasive technology for tissue engineering and regenerative medicine.Photoacoustic imaging (PAI) is a novel hybrid imaging modality that provides excellent optical contrast with the spatial resolution of ultrasound in vivo. The method is widely being investigated in the clinical setting for diagnostic applications in dermatology. In this report, we illustrate the utility of PAI as a non-invasive tool for imaging tattoos. Ten different samples of commercially available tattoo inks were examined for their optoacoustic properties in vitro. In vivo PAI of an intradermal tattoo on the wrist was performed in a healthy human volunteer. Black/gray, green, violet and blue colored pigments provided higher levels of PA signal compared to white, orange, red and yellow pigments in vitro. PAI provided excellent contrast and enabled accurate delineation of the extent of the tattoo in the dermis. Our results reveal the photoacoustic properties of tattoo inks and demonstrate the potential clinical utility of PAI for intradermal imaging of tattoos. Aprotinin inhibitor PAI may be useful as a clinical adjunct for objective preoperative evaluation of tattoos and potentially to guide/monitor laser-based tattoo removal procedures.
Self-management is the backbone of diabetes care. For the patient with type 2 diabetes, this implies making decisions about a healthy diet, regular exercise and taking treatment appropriately. Some patients may experience barriers to the self-management of diabetes, such as lack of support. In this respect, peer support has been identified as a promising strategy in the self-management of diabetes.
The study aimed to explore the experiences of adults with type 2 diabetes who took part in a diabetes peer support intervention in the Free State, South Africa. Such information may lead to the development of practical methods for diabetes self-management and control.
Twelve purposively sampled Sesotho-speaking women (aged 51-84 years) participated in the Mmogo-method®, a visual-based narrative enquiry. Textual data from audio recordings of discussions, visual data from photographs of constructions and field notes were triangulated and analysed thematically.
Participants described the peer support intervention as very valuable. They regarded community health workers as an important source of support. Three themes emerged from the intervention positive lifestyle changes, continuous support, and improved confidence and sense of connectedness. This was a significant finding reported in patients with diabetes, as it will contribute to successfully sustaining effective self-management behaviour.
Peer support for patients with type 2 diabetes appeared to be a valued intervention, as participants related well to community health workers, who are ideally positioned in the healthcare system to provide the service.

This population is expected to experience poorer mental health outcomes compared with heterosexual and cis-gendered people, a phenomenon healthcare providers need to take note of and act upon. This study aimed to explore and describe the mental health challenges of LGBT people. An integrative literature search was conducted. The following electronic databases were searched Academic Search Premier, Africa-Wide Information, Business Source Premier, eBook Collection (EBSCOhost), E-Journals, ERIC, Family & Society Studies Worldwide, Health Source Nursing/Academic Edition, Humanities Source, MasterFILE Premier, MEDLINE, PsycARTICLES, Social Work Abstracts, TOC Premier, WorldCat.org, Taylor and Francis Journals, Biomed Central and Wiley Online Library. An internet search was also carried out using Google and Google Scholar databases. The following search terms were identified 'LGBT' OR 'LGBT community' AND 'mental health challenges/problems' OR 'mental/psychiatric illness'. The reviewed literature comprised research conducted globally between 2010 and 2019. From the 2545 titles, 345 abstracts were examined, resulting in 57 articles. The 57 full-text articles were examined to verify whether they addressed the scope of the literature review, of them, 21 addressed the mental health challenges of LGBT people. Lesbian, gay, bisexual and transgender people experience the following mental health challenges emotional distress, stigmatisation, victimisation, discrimination and barriers to accessing healthcare services. The results showed that although LGBT has been legalised in many countries, LGBT communities still experience significant mental health challenges. Healthcare providers are in a position to address challenges related to social and healthcare structures and act as advocates in order to promote the mental health of LGBT individuals.
The street food sector has become an important component of the food distribution system in many cities in both developing and industrialised countries, particularly for midday meals. However, certain street food can pose a significant risk to consumers because of microbiological contamination.
The aim of this study was to determine the microbial levels of street foods and preparation surfaces in Mangaung Metropolitan Municipality.
The study selected study setting was vending sites close to taxi ranks where prepared meals were accessible to consumers.
The study was conducted in Mangaung Metropolitan Municipality during the winter season. Samples were collected through convenience sampling from the representative towns Thaba Nchu, Botshabelo and Bloemfontein. Using swabs, surface samples were collected and quantified from selective media. Eight beef samples were also collected; the microbial load on each sample was quantified and identified using a RapID kit.
The surface swabs obtained in Botshabelo (1.1 × 10
cfu/m
- 1.1 × 10
cfu/m
) showed higher microbial counts as compared to those obtained in Bloemfontein (1.1 × 10
cfu/m
- 1.1 × 10
cfu/m
) and Thaba Nchu (1.1 × 10
cfu/m
- 1.1 × 10
cfu/m
). Higher microbial counts were observed on meat samples sampled in Thaba Nchu (50 cfu/g x 10
cfu/g), Bloemfontein (48 cfu/g x 10
cfu/g) and Botshabelo (33 cfu/g x 10
cfu/g) when compared to international microbiological standards. After assessing the microbial levels,
and
were identified.
This study confirmed contamination of surfaces and food served by vendors in Mangaung Metropolitan Municipality. The identified foodborne bacteria could pose a public health problem in each specific locality.

Surgical-site infections (SSIs) often occur after surgery for colorectal perforation. We introduced delayed primary closure (DPC) after intrawound continuous negative pressure and irrigation treatment (IW-CONPIT) to prevent SSIs. We aimed to evaluate the efficacy of DPC after IW-CONPIT compared with primary closure (PC) after surgery for colorectal perforation.
We undertook a retrospective study including 22 patients who underwent DPC (DPC group) and 18 patients who underwent PC (PC group) at our hospital between April 2015 and January 2017. The primary outcome was the SSI rate. The secondary outcomes were other complications (<30days), length of hospital stay, and costs.
The SSI rate was significantly lower in the DPC group than in the PC group (40% vs. 94%,
=0.0006). Moreover, superficial and deep incisional SSIs, infectious complications, and Clavien-Dindo classification grade≥2 complications were also significantly diminished in the DPC group. Conversely, the length of hospital stay and costs were not significantly different between the two groups. Multivariate analyses revealed that the significant independent protective factor against SSI after surgery for colorectal perforation was DPC after IW-CONPIT (odds ratio 0.04; 95% confidence interval, 0.002-0.25).
Delayed primary closure after IW-CONPIT reduced SSIs after surgery for colorectal perforation compared with PC.

This study aimed to clarify whether the lying-flat position from prehospital to emergency department settings more effectively improves neurological outcomes of patients suspected with acute stroke over the sitting-up position.
We searched PubMed, the Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi for published randomized controlled trials until September 2019. The study population included patients suspected with acute stroke from prehospital to emergency department settings. We compared outcomes between the lying-flat position and sitting-up position groups. The critical outcome was the modified Rankin Scale score at 90days, and important composite outcomes were 90-day mortality, pneumonia recurrence, and recurrent ischemic stroke. The certainty of evidence of the outcome level was compared using the Grading of Recommendations Assessment, Development, and Evaluation approach.
In total, 881 studies were identified from the databases, and two randomized controlled trials were included in the analysis.
