All FOP systems decreased perceived healthiness of less healthy products. Similar, albeit dampened, effects were seen regarding purchasing intentions. Task 2 participants performed best in the HSR, followed by the TLL, WL and control conditions. Lower health literacy was associated with higher perceived healthiness and purchasing intentions and poorer ranking task performance across all conditions.
All FOP labelling systems, after a brief educational session, improved task performance across a wide spectrum of foods. This effect differed depending on the nutritional quality of the products and the information communicated on labels.Trial Registration NCT03290118.

To mitigate the risk of infection, we removed the HCDs from operating rooms (ORs) at our hospital and since that time (4.5 years ago) we have had no new cases.
This study aimed to describe the microscopic over-under cartilage tympanoplasty technique, provide hearing results and detail clinically significant complications.
This was a retrospective case series chart review study of over-under cartilage tympanoplasty procedures performed by the senior author between January 2015 and January 2019 at three tertiary care centres. Cases were excluded for previous or intra-operative cholesteatoma, if a mastoidectomy was performed during the procedure or if ossiculoplasty was performed. Hearing results and complications were obtained.
Sixty-eight tympanoplasty procedures met the inclusion criteria. The median age was 13 years (range, 3-71 years). The mean improvement in pure tone average was 6 dB (95 per cent confidence interval 4-9 dB; p < 0.0001). The overall perforation closure rate was 97 per cent (n = 66). Revision surgery was recommended for a total of 6 cases (9 per cent) including 2 post-operative perforations, 1 case of middle-ear cholesteatoma and 3 cases of external auditory canal scarring.
Over-under cartilage tympanoplasty is effective at improving clinically meaningful hearing with a low rate of post-operative complications.

Retinal neuronal dysfunction is now recognized as an early event in the diabetic retina before development of overt DR. While detrimental effects of diabetes on the survival and function of inner retinal cells, such as retinal ganglion cells and amacrine cells, are widely recognized, evidence that photoreceptors in the outer retina undergo early alterations in diabetes has emerged more recently. We review data from preclinical and clinical studies demonstrating a conserved reduction of electrophysiological function in diabetic retinas, as well as evidence for photoreceptor loss. Complementing in vivo studies, we discuss the ex vivo electroretinography technique as a useful method to investigate photoreceptor function in isolated retinas from diabetic animal models. Finally, we consider the possibility that early photoreceptor pathology contributes to the progression of DR, and discuss possible mechanisms of photoreceptor damage in the diabetic retina, such as enhanced production of reactive oxygen species and other inflammatory factors whose detrimental effects may be augmented by phototransduction.
Social media has globalised compassion enabling requests for donations to spread beyond geographical boundaries. The use of social media for medical crowdfunding links people with unmet healthcare needs to charitable donors. There is no doubt that fundraising campaigns using such platforms facilitates access to financial resources to the benefit of patients and their caregivers.
This paper reports on a critical review of the published literature and information from other online resources discussing medical crowdfunding and the related ethical questions. The review highlighted the benefits of crowdfunding as well as the under-exploration of the risk of having patients' desires and human rights undermined during online fundraising campaigns. Majority of these campaigns get initiated on behalf of the patients, especially the very sick and dependant. The ethical questions raised relate to the voluntariness of informed consent and the possibility of patients being used as a means to an end. Vulnerability of pential health care needs responsible for driving individuals to use these platforms. The upholding of human rights and the fundamental respect of the individual's wishes is a moral imperative. The need for an ethics framework to guide different stakeholders during medical crowdfunding needs further examination.
Breast cancer is the cancer with the highest incidence and mortality worldwide. Its treatment is multidisciplinary with surgery, systemic therapy, and radiotherapy. In Colombia, according to Globocan 2018, there is an age-standardized incidence rate of 44 per 100,000 women. Radiotherapy improves local and regional control in patients with breast cancer, and it could even improve relapse-free survival and overall survival in patients with nodal disease. The toxicity of this treatment in most cases is mild and transient, but in a low percentage of patients, radiotherapy-induced tumors may develop.
Seven Colombian patients treated for breast cancer at our institution developed radiotherapy-induced tumors between 2008 and 2018. The median age was 54.4 (range 35-72) years. Six patients had locally advanced tumors at the time breast cancer was diagnosed, and all of them received neoadjuvant or adjuvant chemotherapy and radiotherapy. The radiotherapy-induced tumors were five sarcomas, one of which was a well-difs a risk factor for the development of soft tissue tumors.
Mozambique, same as many other tropical countries, is at high risk of arthropod-borne virus (arbovirus) diseases and recently two dengue virus (DENV) outbreaks occurred in the northern part of the country. The occurrence of some important vector species, such as Aedes (Stegomyia) aegypti (Linnaeus) and Ae. (Stg.) albopictus (Skuse), besides several other sylvatic vectors, have been reported in the country, which may indicate that the transmission of some arboviruses of public health importance may involve multiple-vector systems. Therefore, knowing the occurrence and distribution of existing and the new important vectors species, is crucial for devising systematic transmission surveillance and vector control approaches. The aim of this study was to map the occurrence and distribution of mosquito species with potential for transmitting arboviruses of human and veterinary relevance in Niassa Province, Northern Mozambique.
Field entomological surveys were undertaken in April 2016 in Lago District, Niassa Pro To our knowledge, this is the first detection of Ae. luteocephalus in Mozambican territory, a vector species of yellow fever virus (YFV), Zika virus (ZIKV) and dengue virus (DENV) in Africa. Further studies are encouraged to investigate the role of Ae. luteocephalus in the transmission of arboviral diseases in Mozambique.

Pulmonary arterial hypertension (PAH) is a fatal disease that results from cardio-pulmonary dysfunction with the pathology largely unknown. Insulin-like growth factor binding protein 2 (IGFBP2) is an important member of the insulin-like growth factor family, with evidence suggesting elevation in PAH patients. We investigated the diagnostic and prognostic value of serum IGFBP2 in PAH to determine if it could discriminate PAH from healthy controls and if it was associated with disease severity and survival.
Serum IGFBP2 levels, as well as IGF1/2 levels, were measured in two independent PAH cohorts, the Johns Hopkins Pulmonary Hypertension program (JHPH, N = 127), NHLBI PAHBiobank (PAHB, N = 203), and a healthy control cohort (N = 128). The protein levels in lung tissues were determined by western blot. The IGFBP2 mRNA expression levels in pulmonary artery smooth muscle cells (PASMC) and endothelial cells (PAEC) were assessed by RNA-seq, secreted protein levels by ELISA. Association of biomarkers with clinic
IGFBP2 protein expression was increased in the PAH lung, and secreted by PASMC. Elevated circulating IGFBP2 was associated with PAH severity and mortality and is a potentially valuable prognostic marker in PAH.

Anti-cancer effect of lapachol contained in Tabebuia avellandae has been poorly understood until now.
The aim of this study was to investigate the inhibitory effect of lapachol on MMPs related to cell invasion. Its action mechanism was elucidated by analyzing the activity and the expression of MMPs and the proteins involved in the signalling pathway of cell invasion.
The cytotoxicity of lapachol was evaluated by MTT assay in HT1080 cells. The effects of lapachol on the expression and the activation of MMPs were analyzed by western blot, immunofluorescence staining and gelatin zymography assays. Their gene expression was analyzed by RT-PCR, and metastasis was evaluated by cell invasion assay.
Lapachol below 2 µM showed no cytotoxicity. It was observed that lapachol above 0.5 µM inhibited the activation of MMP-2 and MMP-9 stimulated by PMA. In particular, the protein and gene expression levels of MMP-2 stimulated by PMA were remarkably decreased in the presence of lapachol at 1 µM compared with PMA treatment group. In addition, lapachol increased the expression level of TIMP-1 compared with PMA treatment group. Moreover, lapachol decreased the expression level of p-p38 among MAPKs compared with PMA treatment group. It was also found that the expression level of p65, a part of NF-kB, in nuclei was reduced in the presence of lapachol above 0.5 µM compared with PMA treatment group. In addition, lapachol inhibited the invasion of human fibrosarcoma cells stimulated with VEGF.
Above results suggest that lapachol could play an important role in the modulation of MMPs related to cell invasion via the increase of TIMP-1 expression as well as the inactivation of p38 through NF-kB transcription factor.
