The diagnosis of neurocysticercosis (NCC) is principally based on neuroimaging (magnetic resonance imaging or computed tomography), instrumentation that is scarcely available in the rural regions where Taenia solium transmission, primarily occurs due to poor sanitation conditions. Immunological assays for antigen or antibody detection complement the neuroimaging approach. However, no field-applicable assays to diagnose viable NCC or to guide the referral of cases for neuroimaging or for appropriate management are available. We performed an exploratory study on urine and serum samples using 1H-nuclear magnetic resonance (NMR)-based metabolomics to discriminate NCC patients (n = 14) from healthy control subjects (n = 22). Metabolic profiles demonstrated a discrimination between the urines of NCC patients and noninfected control subjects with a moderate predictive accuracy (R2 = 0.999, Q2 = 0.434). NMR metabolomics analysis has been proven useful in depicting biomarkers linked to other infectious diseases, various types of cancer, and other disorders. Our results, albeit preliminary, open a door to the development of better methods for detecting NCC through the identification of biomarkers participating in disturbed metabolic pathways.

Severe anaemia is associated with high in-hospital mortality among young children. In malaria-endemic areas, surviving children also remain at increased risk of mortality for several months after hospital discharge. We aimed to compare the risks of morbidity and mortality among children discharged from hospital after recovery from severe anaemia versus other health conditions in malaria-endemic settings in Africa.

Following PRISMA guidelines, we searched PubMed, Scopus, Web of Science, and Cochrane Central from inception to Nov 30, 2021, without language restrictions, for prospective or retrospective cohort studies and randomised controlled trials that followed up children younger than 15 years for defined periods after hospital discharge in malaria-endemic countries in Africa. We excluded the intervention groups in trials and studies or subgroups involving children with sickle cell anaemia, malignancies, or surgery or trauma, or those reporting follow-up data that were combined with the in-hospital perioted with severe acute malnutrition (regardless of severe anaemia) also had a higher 6-month mortality after discharge than those admitted for other reasons (n=2 studies; RR=3·12, 2·02-4·68; p<0·0001; I

=54·7%). Other predictors of mortality after discharge included discharge against medical advice, HIV, bacteraemia, and hypoxia.

In malaria-endemic settings in Africa, children admitted to hospital with severe anaemia and severe acute malnutrition are at increased risk of mortality in the first 6 months after discharge compared with children admitted with other health conditions. Improved strategies are needed for the management of these high-risk groups during the period after discharge.

There is little evidence about childhood cancer burden in the WHO Eastern Mediterranean region (EMR). We aimed to provide an estimate of childhood cancer burden in the EMR, examine the connection between age-standardised mortality rate and level of income (gross domestic product [GDP] per capita), and reflect on the current status of childhood cancer registration in the EMR.

Using the GLOBOCAN 2020 data from the Cancer Surveillance Unit of the International Agency for Research on Cancer, we extracted data for childhood cancer (at ages 0-14 years) incidence, prevalence, and mortality for 22 countries in the EMR, the EMR as a whole, and other WHO regions, and categorised by main cancer types. Childhood cancers were classified according to the 10th revision of the International Classification of Diseases. We also searched MEDLINE, Google Scholar, and the grey literature between May 17 and Aug 2, 2021, for English-language articles and reports about the status of childhood cancer registration in the EMR. We f100 000 children at risk in Somalia. A negative correlation was found between countries' GDP per capita (income level) and mortality rates (r=-0·77, p<0·0001). The scarcity of data and quality of cancer registries in EMR countries prevented further analysis.

Given the variable quality and coverage of cancer registries in EMR countries, these findings are likely to be underestimates. Nevertheless, these data, especially the high mortality rates, reflect a need for effective national childhood cancer plans in line with the WHO Global Initiative for Childhood Cancer to improve survival.

Due to waning immunity and protection against infection with SARS-CoV-2, a third dose of a homologous or heterologous COVID-19 vaccine has been proposed by health agencies for individuals who were previously primed with two doses of an inactivated COVID-19 vaccine.

We did a randomised, open-label, controlled trial to evaluate the safety and immunogenicity of heterologous boost immunisation with an orally administered aerosolised adenovirus type-5 vector-based COVID-19 vaccine (Ad5-nCoV) in Chinese adults (≥18 years old) who had previously received two doses of an inactivated SARS-CoV-2 vaccine-Sinovac CoronaVac. Eligible participants were randomly assigned (111) to receive a heterologous booster vaccination with a low dose (1·0 × 10

viral particles per mL; 0·1 mL; low dose group), or a high dose (1·0 × 10

viral particles per mL; 0·2 mL; high dose group) aerosolised Ad5-nCoV, or a homologous intramuscular vaccination with CoronaVac (0·5 mL). Only laboratory staff were masked to group assignment. The pred Ad5-nCoV is safe and highly immunogenic in adults who have previously received two doses of CoronaVac as the primary series vaccination.

The discovery that RNF213, which encodes an unconventional E3 ubiquitin ligase, is the major susceptibility gene for moyamoya disease in people from east Asia has opened new avenues for investigation into the mechanisms of disease and potential treatment targets. The Arg4810Lys variant of the gene is most strongly associated with moyamoya disease, but the penetrance is lower than 1%, suggesting a synergistic relationship with additional environmental and genetic risk factors. White people carry less common non-Arg4810Lys variants of RNF213, which partly explains the lower prevalence of moyamoya disease in European countries and in the USA than in east Asian countries. Several monogenic moyamoya syndromes possess the radiological characteristics of moyamoya disease and have been associated with multiple genes and pathways involved in moyamoya angiopathy pathogenesis. Further clarification of the genetic and environmental factors that contribute to the emergence of moyamoya angiopathy could enable development of new treatment strategies for moyamoya disease.

Reversed-contrast testing is easy to perform via electronic devices and may improve reading performance and the quality of life of most glaucoma patients.

Electronic devices are becoming increasing popularity and most devices have easily adjustable contrast settings. This study investigated near vision acuity and preference between the standard visual acuity chart (black text on white background) and a reversed-contrast chart (white text on black background) in glaucoma patients with decreasing contrast sensitivity.

This cross-sectional study evaluated 177 eyes of 177 patients from a single glaucoma clinic. The better eye of primary glaucoma patients (visual acuity of 6/20 or better) was evaluated. Patients with any other condition affecting visual acuity or reading performance were excluded. Near visual acuity was measured using a device with an anti-glare screen at 40 cm distance for both standard and reversed-contrast charts.

Glaucoma patients had a significantly better average near visual acuity using the reversed-contrast chart than using the standard chart (median best-corrected visual acuity, LogMAR=0.12; interquartile range=0.18 vs median best-corrected visual acuity, LogMAR=0.2; interquartile range=0.26; respectively;

<0.01), with more prominent differences in the advanced glaucoma group (median best-corrected visual acuity of reversed contrast chart median best-corrected visual acuity of standard chart=0.120.2, 0.120.13, and 0.180.22 in the early, moderate, and severe groups, respectively,

<0.01 in early and severe group and

=0.02 in moderate group). One hundred and nine (109) out of 177 patients (61.58%) preferred the reversed contrast version.

Reversed contrast materials may improve the reading performance and quality of life of patients with glaucoma, especially those with severe disease.

The next generation of lightweight and tactile robots have provided a great opportunity to be used for a wide range of applications from medical examination, diagnosis, therapeutic procedures to rehabilitation and assistive robotics. They can potentially outperform current medical procedures by exploiting the com- plementary strengths of humans and computer-based technologies. In this study, the importance of human- robot interaction is discussed and technological re- quirements and challenges in making human-centered robot platforms for medical applications is addressed.Robotic systems for head and neck surgery are at different stages of technical development and clinical application. buy Ivacaftor Currently, robotic systems are predominantly used for transoral surgery of the pharynx and larynx. Robotic surgery of the neck, the thyroid, and the middle and inner ear is much less common; however, some oncological and functional outcomes have been reported. This article provides an overview of the current state of robot-assisted head and neck surgery with a special emphasis on patient benefit and postoperative quality of life (QoL). The focus is placed on the role of transoral robotic surgery (TORS) for the resection of oropharyngeal carcinomas. For this application, reported long-term outcomes show functional post-operative advantages for selected oropharyngeal cancer patients after TORS compared to open surgery and primary radiotherapy. Since TORS also plays a significant role in the context of potential therapy de-escalation for HPV-positive oropharyngeal cancer patients, ongoing trials are presented. Regarding the evaluation of the therapeutic benefit and the QoL of cancer patients, special attention has to be paid to the large degree of variability of individual patients' preferences. Influencing factors and tools for a detailed assessment of QoL parameters are therefore detailed at the beginning of this article. Notably, while some robotic systems for ear and skull base surgery are being developed in Europe, TORS systems are mainly used in North America and Asia. In Europe and Germany in particular, transoral laser microsurgery (TLM) is a well-established technology for transoral tumor resection. Future trials comparing TORS and TLM with detailed investigation of QoL parameters are therefore warranted and might contribute to identifying suitable fields for the application of the different techniques.
