Centipede envenomation occurs commonly in tropical and subtropical countries. In most cases, centipede envenomation causes benign clinical manifestations. Serious complications are reported occasionally. Clinical studies regarding centipede envenomation are limited to case reports and case series. This study aimed to determine the prevalence and clinical characteristics of centipede bites in Bangkok, Thailand.

This was a retrospective medical record review study. We included patients who were clearly envenomated by a centipede presenting to the emergency department of a tertiary university hospital in Bangkok from January 1, 2006, to December 31, 2015. Data were collected on demographics, details of the exposure, signs, symptoms, treatment, and complications of envenomation.

A total of 245 cases were included. The prevalence of centipede bite was 0.0367%. The majority were female (56.7%). The median age was 34.6 years (range 1 month to 90 years). The number of envenomations was highest from October throopolitan city in Thailand, there were centipede bites every month, especially during the last three months of each year. Nearly all patients had local effects. In contrast, serious complications such as anaphylaxis and systemic infection only occurred occasionally.Contamination of environmental sources such as soils, sediments and rivers and human exposure caused by several endocrine disrupting compounds (EDCs) are considered as the most challenging issues of today’s world. EDCs cover a wide variety of compounds ranging from phthalates to parabens and bisphenols (BPs) are the leading group among them. BPs are widely used during the production of different plastic materials such as food and beverage containers, toys, medical equipment and baby bottles that we use in every aspect of our lives. BPs may migrate from those products to different media under certain conditions and this situation causes chronic exposure for humans and other creatures in the environment. Especially bisphenol A (BPA) and its other analogues such as bisphenol F, bisphenol S and tetrabromobisphenol that have similar structures and are preferred as alternatives to BPA cause harmful adverse effects such as endocrine disruption, neurotoxicity, genotoxicity and cytotoxicity. There are legal restrictions and prohibitions by the European Union (EU) in order to prevent possible harmful effects. Therefore, it is important to develop highly sensitive, fast, easy to use and cheap sensors for the determination of BPs in biological, environmental and commercial samples. Electrochemical sensors, which are one of the most widely, used analytical techniques, provide these conditions. Additionally, it is possible to enhance the performance of electrochemical sensors with nanomaterials, molecularly imprinted polymers or aptamer based technologies. This review aims to give comprehensive information about BPs with summarizing most recent applications of electrochemical sensors for their determination in different samples.

Tranexamic acid (TXA) is widely used across surgical specialties to reduce perioperative bleeding. It has been shown to be effective in spinal surgery and lower limb arthroplasty. Among all languages, there are no systematic reviews or meta-analyses investigating its clinical effectiveness for all types of shoulder surgery.

To investigate the clinical effectiveness of TXA in all types of shoulder surgery, including open and arthroscopic procedures. To investigate the effect of TXA on bleeding and non-bleeding-related outcomes.

Systematic review and meta-analysis.

A protocol for the study was designed and registered with PROSPERO (CRD42020185482). The literature search included the MEDLINE, Embase, PsycINFO, and Cochrane Library databases. All randomized controlled trials evaluating the use of TXA against placebo, in all types of shoulder surgery, were included. Assessments were undertaken for risk of bias and certainty of evidence. The primary outcome was total blood loss. Secondary outcomes included h low risk of bias for specific surgical shoulder procedures are required.

TXA can be used across shoulder surgery to reduced perioperative blood loss. The use of TXA may have other beneficial features, including reduced postoperative pain and reduced operative time.

The “one-with-many” (OWM) model (Kenny et al., 2006; Kenny & Winquist, 2001) was specifically constructed for and is used to examine features of multiple dyadic relationships that one set of focal persons (e.g., therapists, physicians) has with others (e.g., multiple clients, multiple patients). Originally, the OWM model was constructed for and applied to cross-sectional data. However, the model can be extended to accommodate and may be particularly useful for the analysis of intensive repeated measures data now being obtained through experience sampling and social media. This article (a) provides a practical tutorial on fitting the OWM model, (b) describes how the OWM model is extended for analysis of repeated measures data, and (c) illustrates application of the OWM model using reports about interpersonal behavior and benefits individuals experienced in 64,111 social interactions during 9 weeks of study (N = 150). Our presentation highlights the utility of the OWM model for examining interpersonal processes in everyday life.

PLX4032 supplier The present investigation used steady state visual evoked potential (ssVEP) frequency tagging to test the hypothesis that learning to categorize novel objects via labeling prompts a competitive advantage over concurrently presented stimuli. In the learning (label-training) phase, participants (n = 24) categorized objects according to two different species labels and faces according to gender. A control group (n = 26) viewed the same stimuli without label learning. Before and after learning, faces and objects were superimposed and viewed concurrently while periodically turned on and off at unique temporal rates (5/s or 6/s). The spectral power of the ssVEP at each frequency was projected to an L2 (minimum) norm estimated source space, and competition between faces and objects was compared using permutation-controlled mass univariate t tests. Results showed that, only in the training group, learning to label novel objects led to a competitive advantage over faces across a network of occipito-temporal and fronto-parietal cortical regions.
