Chronic rhinosinusitis affects approximately 5%-2% of the general population worldwide. Steroid implants after endoscopic sinus surgery (ESS) have drawn considerable interest for their cost savings, but relevant guidelines indicate that evidence on this topic is of low quality with high heterogeneity. The purpose of this study was to examine the efficacy of steroid implants after ESS by synthesizing relevant randomized controlled trials (RCTs).

Two authors independently assessed the eligibility of potential references from five biomedical databases. They further extracted relevant data from the included studies, including (a) mean, standard deviation, or standard error for Lund-Kennedy endoscopic (LKE) score and Perioperative Sinus Endoscopy (POSE) score and (b) events and sample sizes of each group for further intervention. Data were pooled in a random-effects model, and results were presented as the weighted mean difference (WMD) or risk ratio (RR) with 95% confidence interval (CI) and I

.

Eleven RCTs (n=853) were included and showed that the steroid implant group had lower LKE scores (WMD, -1.19; 95% CI, -1.75 to -0.62; I

=0%) and POSE scores (WMD, -1.62; 95% CI, -2.47 to -0.76; I

=48%) than the placebo implant group at postoperative week 2. Moreover, the reoperation rate in the steroid implant group was also lower than in the placebo implant group (RR, 0.49; 95% CI, 0.30 to 0.80; I

=0%). However, no significant difference was observed in the postoperative oral steroid requirement between both groups.

Collectively, steroid implant decreases LKE and POSE among patients receiving ESS in the short term, but long-term effects remain unclear. Patient-based outcomes are worth further discussion in the future.

Recycling methods are preferable to reduce the impact of plastic pollution to some extent. However, most of the recycling techniques are associated with different drawbacks, high cost and downgrading of product quality being among the notable ones. The sustainable option here is to upcycle the plastic waste to create high-value materials to compensate for the cost of production. Several upcycling techniques are constantly being investigated and explored, which is currently the only economical option to resolve the plastic waste issue. This Review provides a comprehensive insight on the promising chemical routes available for upcycling of the most widely used plastic and mixed plastic wastes. The challenges inherent to these processes, the recent advances, and the significant role of the science and research community in resolving these issues are further emphasized.Molecular recognition is essential to the development of biomaterials. Aptamers are a unique class of synthetic ligands interacting with not only their target molecules with high affinities and specificities but also their complementary sequences with high fidelity. Thus, aptamers have recently attracted significant attention in the development of an emerging class of biomaterials, that is, aptamer-functionalized hydrogels. In this review, we introduce the methods of incorporating aptamers into hydrogels as pendant motifs or crosslinkers. We further introduce the functions of these hydrogels in recognizing proteins, cells, and analytes through four applications including protein delivery, cell capture, regenerative medicine, and molecular biosensing. Notably, as aptamer-functionalized hydrogels have the characteristics of both aptamers and hydrogels, their potential applications are broad and beyond the scope of this review.

This study evaluated the added value of a virtual facilitator tool to an enhanced community conversation (ECC) programme to improve infant and young child feeding (IYCF) practice among children under the Growth through Nutrition Activity programme in Ethiopia. The study used a quasi-experimental design with a control group. Pregnant and/or lactating women were the study population for both study groups. The intervention (ECC + VF) group received all the same components as the control group but had the addition of in-person ECC meetings supplemented with audio-recorded virtual facilitators (VF) sessions designed to complement the monthly meeting lesson or topic. A difference in difference analysis was employed using generalized linear mixed model (GLMM) in Stata version 15.0 (Stata Corporation, College Station, TX). A p-value of less than or equal to 0.05 was considered significant for all tests. Accordingly, a 13.6% change in iron folic acid (IFA) intake for 3 months and above was observed in the intervention group. Even though not statistically significant, large to moderate positive changes in child minimum diet diversity (20%), minimum acceptable diet (18%) and women diet diversity (7.9%) were observed in the intervention group. check details This study identified the use of virtual facilitators as a modality to transmit standard nutrition messages during ECC programmes for optimal IYCF practices. The findings strengthen the notion that using a combination of SBCC approaches has advantage over a single method in improving important nutritional practices.

This study aimed to risk-stratify chest pain as a presenting symptom in patients with a diagnosis of pulmonary thromboembolism (PE) to assess for any association. In addition, this study aimed to assess traditionally acknowledged PE risk factors in an Australian population.

This was a retrospective single-centre cohort study assessing patients who presented to our emergency department during the period of 1 January 2019 to 1 January 2020. 730 consecutive patients who went on to computed tomography pulmonary angiography (CTPA) examination after presentation were included.

The rate of CTPA being positive in this study was 11.6% (85/736). Chest pain was associated with a non-significant reduction in the odds of PE (OR 0.774, P=0.327). Univariate analysis showed significantly increased odds of a diagnosis of PE with presentation for leg pain/swelling (OR 6.670, P<0.001). Multivariate analysis showed increasing age (OR 1.018, 95% CI 1.002-1.034, P=0.024), clinical signs of a DVT (OR 3.194, 95% CI 1.803-5.
