A four-year-old girl presented with accidental ingestion of 200 tablets of Calcarea phosphorica. Although she was asymptomatic, she was found to have marked hypocalcaemia with a prolonged QTc interval on electrocardiogram. She was successfully treated with intravenous calcium, followed by oral maintenance.Introduction There are positive aspects regarding the prescribing of fixed dose combinations (FDCs) versus prescribing the medicines separately. However, these have to be balanced against concerns including increased costs and their irrationality in some cases. Consequently, there is a need to review their value among lower- and middle-income countries (LMICs) which have the greatest prevalence of both infectious and noninfectious diseases and issues of affordability.Areas covered Review of potential advantages, disadvantages, cost-effectiveness, and availability of FDCs in high priority disease areas in LMICs and possible initiatives to enhance the prescribing of valued FDCs and limit their use where there are concerns with their value.Expert commentary FDCs are valued across LMICs. Advantages include potentially improved response rates, reduced adverse reactions, increased adherence rates, and reduced costs. Concerns include increased chances of drugdrug interactions, reduced effectiveness, potential for imprecise diagnoses and higher unjustified prices. Overall certain FDCs including those for malaria, tuberculosis, and hypertension are valued and listed in the country's essential medicine lists, with initiatives needed to enhance their prescribing where currently low prescribing rates. Proposed initiatives include robust clinical and economic data to address the current paucity of pharmacoeconomic data. Irrational FDCs persists in some countries which are being addressed.Introduction Despite the promising results of intralesional vitamin D in verruca treatment; its precise mechanism of action is not fully understood.Aim of the work To investigate immunohistochemical expression of cathelicidin (LL 37) before and after injection of vitamin D in verruca vulgaris and to clarify its possible role in pathogenesis of verruca.Patients and methods This study included 20 patients with multiple verrucae vulgaris. Vitamin D was intralesionally injected every 2 weeks for a maximum of 4 sessions or clearance of verrucae. Skin biopsies were taken from the patients before and at the end of the study and compared to skin samples from ten apparently healthy, age and sex matched individuals for histopathological and immunohistochemical assessment of LL37 expression.Results Eight (40%) verrucae showed complete response, seven (35%) showed partial response and five (25%) showed no response. Decreased epidermal thickness and reduced density of inflammatory cells in dermis were observed after injection. Significant increase in LL37 intensity of expression was observed after intralesional injection of vitamin D3 (p = 0.003) and in verrucae showing complete clinical response (p = 0.022).Conclusions Intralesional injection of vitamin D is effective and safe treatment for verruca vulgaris and causes increase in LL37 expression.Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that is potentially life-threatening and can affect any organ. The complex pathogenesis and heterogeneity of the disease, among other factors, present significant challenges in developing new therapies. Knowledge gained over many years has implicated type I interferon (IFN) in the pathogenesis of SLE and anti-IFN therapies hold promise as a much-needed future treatment for SLE. Anifrolumab, a human monoclonal antibody against the type I IFN receptor, has recently been evaluated in two Phase III clinical trials for the treatment of moderate-to-severe SLE. Here, we review the clinical efficacy and safety of anifrolumab and discuss the potential challenges in determining the optimal SLE patient subgroup for treatment.We aimed to investigate associations of dietary intakes with unhealthy metabolic phenotype development, in normal weight and overweight/obese adults separately. A total of 1114 individuals, aged ≥19 years, with healthy phenotype in the third examination cycle of Tehran Lipid and Glucose Study were followed until the fifth examination. Dietary intakes were estimated using the food frequency questionnaires, collected during the study. The participants were grouped as normal weight and overweight/obese according to the baseline body mass index (BMI). Unhealthy metabolic status was determined as having more than one component of metabolic syndrome using the Joint Interim Statement. Regardless of BMI, higher intakes of magnesium, dairy products, poultry, apples/pears, citrus fruits, and tea/coffee decreased the risk of developing unhealthy phenotype, while higher intakes of fast foods, organ meats, and potatoes increased the risk. Food intake can influence the transition to unhealthy phenotype in metabolically healthy adults, irrespective of the BMI status.Toll-like receptors (TLRs) are widely expressed pattern recognition receptors that bind to conserved molecular patterns expressed by pathogens and damaged cells. After recognition, activated TLRs induce the expression of various proinflammatory and antiviral molecules. Thus, TLRs are potential targets for treatment strategies aimed at boosting the adaptive immune response to vaccines, controlling infections, enhancing immune responses during tumor treatment and attenuating immune responses in inflammatory disorders. This Special Report examines the potential of TLRs as targets for the treatment of cancer, infections and inflammatory diseases. Here, we make a particular emphasis on molecules capable of modulating TLRs and their therapeutic applications.Objective To review the qualitative literature on mobile health applications for people with dementia.Methods A systematic review was undertaken. Five databases were searched using relevant keywords. Titles, abstracts and full-text papers were screened independently by two reviewers. Data extraction and quality assessment were conducted. Analysis was guided by framework synthesis and underpinned by the Digital Health Engagement Model.Results Nine studies were included. Three themes emerged around the experiences of people with dementia when using health apps. The technology seemed to improve some aspects of physical, mental and social health such as stimulating cognitive function and communication skills. When implementing health applications with persons with dementia six themes came to light. How well an application or mobile device was designed and the quality of information on it, seemed to influence use. Digital knowledge and skills were also needed to engage with the technology. One's personal lifestyle and agency were other relevant factors affecting implementation, along with the health of an individual with dementia.Conclusion Further research examining the efficacy of health apps for people with dementia is required. Utilizing co-design approaches to create mobile technology with those with dementia should also be considered.PROSPERO Registration Number CRD42015029846.Objective Both genetic variants and maternal blood mRNA levels of EBF1 gene have been linked to sPTB. Animal and human studies suggest that specific EBF1-based miRNAs are involved in various physiological and pathophysiological processes. However, to date, we did not find any reports of EBF1-based miRNAs or miRNA transcripts in relation to sPTB. We therefore aimed to examine whether maternal blood early B cell factor 1 (EBF1) gene-based microRNA (miRNA) transcripts can be used for detecting risk of spontaneous preterm birth (sPTB).Methods We conducted a nested case-control study within a Canadian cohort consisting of 1878 singleton pregnancies enrolled from May 2008 to December 2010 in Calgary, Alberta, Canada. We used a public gene expression dataset (GSE59491) derived from maternal blood in trimesters 2-3 that included women with sPTB (n = 51) and term births (n = 106) matched for maternal age, race/ethnicity, pre-pregnancy body mass index, smoking during pregnancy, and parity within the Canadian cohort. Tw trimester were significantly associated with sPTB. The odds ratios (95%CIs) for highest versus lowest tertile of the four miRNA transcripts were 3.01-5.25(1.21-13.14, p ≤ .018). The combined 4-miRNA transcripts' score significantly improved the classification of sPTB compared to individual miRNA transcripts (AUC increased from 0.65-0.69 to 0.82, p ≤ .0034) and showed a sensitivity for sPTB of 0.81 and a specificity of 0.72. The final ROC model of the EBF1-based 4 miRNA transcripts' score in cases and controls had no significant overfitting issue.Conclusions Maternal blood EBF1-based miRNA transcripts may, along with other biomarkers, be useful in screening for sPTB risk in 3rd trimester. Our results also provide clues for further study of potential molecular mechanisms underlying the relationship between EBF1 gene and sPTB, e.g. connecting genetic variants, mRNA expression, and miRNA regulation.Background and purpose - The successful eradication of calcaneus infection with limb salvage remains a challenge. We describe the outcomes of cortical bone windowing followed by eggshell-like debridement and implantation of antibiotic-loaded calcium sulphate (CS) for localized (Cierny-Mader type III) calcaneal osteomyelitis (CO).Patients and methods - We report a retrospective study of 34 patients. Infection followed trauma or orthopedic surgery in 30 patients and hematogenous spread in 4 patients. 31 patients had a sinus tract, accompanied by a soft tissue defect in 3 patients. All patients received cortical bone windowing, debridement, multiple sampling, local implantation of vancomycin- and gentamicin-loaded CS, skin closure or flap coverage, and culture-specific systematic antibiotic treatment in a single-stage procedure. Patients were followed up for a median of 26 months.Results - Infection was eradicated in 29 patients after the single-stage surgery, and all of the 5 recurrent infections were cleared by repeated surgery without amputation. Other adverse events included 11 patients with aseptic wound leakage and 1 unrelated death. Compared with those before surgery, the median postoperative scores of the American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale (65 vs. 86 vs. 89) and the visual analog scale (VAS) for pain (6 vs. 3 vs. 1) improved at the 1-year and 2-year follow-up.Interpretation - This single-stage protocol, cortical bone windowing, and eggshell-like debridement combined with local implantation of antibiotic-loaded CS is effective in treating type III CO. However, the incidence of aseptic wound leakage is high.To ensure that adolescents adhere to programmes promoting healthy behaviors, these programmes must be appealing and interesting. This study aims to characterize and assess the devices, operating system and type of mobile apps frequently used by adolescents; understand the features that mHealth apps should have to be appealing; comprehend the facilitators and barriers for adolescents to use mHealth apps. The sample comprised 165 adolescents (12-18 years) from the main population, recruited in 2018. Most participants used smartphones and the Android system. Food and physical activity suggestions were considered the most important features for an mHealth app. 62.6% had never tried an mHealth app. For those who had tried one, 26.0% stated it was to improve health status/lifestyle. Their favorite feature was physical exercise tips/plans (41.8%). read more Adolescents pointed out that the reasons that made them keep using the app were utility and interest (35.7%). Regarding possible barriers, 48.4% reported a lack of a senseof need/practical utility, and 18.
