A simple, low-cost pyrene derivative containing a benzilmonohydrazone moiety has been exploited for the selective detection of Cu2+ by colorimetric, absorption, emission and bio-imaging methods. The sensitivity of the fluorescence based assay is 7.8 nM for Cu2+, which is far below the limit mentioned in the World Health Organization.

The quality of drinking water can no longer be taken for granted and has been the subject of tremendous attention from pressure groups and the media due to poor service delivery in South Africa. Furthermore, many of the older water treatment plants are incapable of effectively reducing microbes to safe levels. Unfortunately there are various definitions of ‘safe’. The South African government considers 10 or less viable Cryptosporidium oocysts an infective dose, while the USA and UK governments believe that one viable Cryptosporidium oocyst is an infective dose. To add to the confusion the World Health Organization recommends above 99.99% microbial reduction as safe. In Africa it really depends on how compromised your immune system is and age and nutritional level at the time of consumption of contaminated water. How can anyone protect themselves from consuming water contaminated with pathogenic microorganisms? The ceramic filter offers the poor a simple, effective and economical way of producing potable water. We report on the successful testing of a low-cost, locally produced ceramic filter (OUTBAC) with removal efficiencies in excess of 99.99% that therefore meets the World Health Organization household water treatment system criterion for safe water for a family of five at an affordable cost per year.

Coenen M et al. [Recommendation for the collection and analysis of data on participation and disability from the perspective of the World Health Organization]. Bundesgesundheitsblatt Gesundheitsforschung Gesundheitsschutz 2016; 59: 1060–1067 Um eine gleichberechtigte Teilhabe an der Gesellschaft von Menschen mit Behinderung zu ermöglichen, werden zunächst Daten zu vorhandenen Einschränkungen gebraucht. Erst wenn diese detailliert erhoben wurden, können Konzepte zur Beseitigung von Problemen entwickelt werden. Ein standardisiertes Erhebungsinstrument für alle Aspekte der Funktionsfähigkeit fehlte jedoch bisher.

A Organização Mundial da Saúde - OMS confirmou a circulação internacional do novo Coronavírus em janeiro de 2020, nomeando-o como COVID-19 e, declarando uma pandemia. É de extrema importância que durante a pandemia, os profissionais de saúde tenham acesso e conhecimento sobre o uso correto dos Equipamentos de Proteção Individual (EPIs) e suas indicações, tomando assim, as devidas precauções na prevenção de infecções. O presente estudo buscou identificar a padronização mundial quanto ao uso dos EPIs utilizados no atendimento a pacientes suspeitos e/ou confirmados de COVID-19 no Brasil, EUA, China, Espanha, Itália e demais países europeus. Os guidelines apresentam a padronização quanto ao uso dos EPIs utilizados no atendimento a suspeitos e/ou confirmados de COVID-19, indo ao encontro das recomendações fornecidas pela OMS. Até o momento, o uso de EPIs é sem dúvida a estratégia mais importante e eficaz para proteger os profissionais de saúde durante a assistência ao paciente com COVID-19.Descritores: Infecções por Coronavírus, Equipamento de Proteção Individual, Pessoal de Saúde, Enfermagem. Recommendations for personal protective equipment to combat COVID-19Abstract: The World Health Organization - WHO confirmed the international circulation of the new Coronavirus in January 2020, naming it as COVID-19 and declaring a pandemic. It is extremely important that during the pandemic, health professionals have access and knowledge about the correct use of Personal Protective Equipment (PPE) and its indications, thus taking appropriate precautions to prevent infections. The present study sought to identify the worldwide standardization regarding the use of PPE utilized to take care of suspected and confirmed patients with COVID-19 in Brazil, USA, China, Spain, Italy and other European countries. The guidelines present a standardization regarding the use of PPE utilized to take care of suspected and confirmed with COVID-19, in line with the recommendations provided by WHO. To date, the use of PPE is undoubtedly the most important and effective strategy to protect healthcare professionals during care for patients with COVID-19.Descriptors: Coronavirus Infections, Personal Protective Equipment, Health Personnel, Nursing. Recomendaciones para el equipo de protección personal para combatir COVID-19Resumen: La Organización Mundial de la Salud - La OMS confirmó la circulación internacional del nuevo Coronavirus en enero de 2020, nombrándolo COVID-19 y declarando una pandemia.

El presente estudio buscó identificar la estandarización mundial con respecto al uso de EPP utilizado para atender a pacientes sospechosos y/o confirmados con COVID-19 en Brasil, Estados Unidos, China, España, Italia y otros países europeos. Las pautas presentan la estandarización con respecto al uso de EPP utilizado para cuidar COVID-19 sospechoso y/o confirmado, de acuerdo con las recomendaciones proporcionadas por la OMS. Hasta la fecha, el uso de EPP es, sin duda, la estrategia más importante y efectiva para proteger a los profesionales de la salud durante la atención de pacientes con COVID-19.Descriptores: Infecciones por Coronavirus, Equipo de Protección Personal, Personal de Salud, Enfermería.

Coronaviruses are a family of viruses that cause illness such as respiratory diseases or gastrointestinal diseases. Respiratory diseases can range from the common cold to more severe diseases. A novel coronavirus outbreak was first documented in Wuhan, Hubei Province, China in December 2019. The World Health Organization (WHO) has declared the coronavirus disease 2019 (COVID-19) a pandemic. A global coordinated effort is needed to stop the further spread of the virus. A novel coronavirus (nCoV) is a new strain that has not been identified in humans previously. Once scientists determine exactly what coronavirus it is, they give it a name (as in the case of COVID-19, the virus causing it is SARS-CoV-2).
