Although it is important not to ignore clinical symptoms suggestive of a urinary tract infection (UTI), especially in antenatal patients, samples which have no abnormalities detected on bedside urinalysis may not need to be sent to the laboratory for culture and sensitivity (C&S) testing. If leucocytes, blood and/or protein are found in the samples, then they may need to be sent to the laboratory for further assessment, but no treatment needs to be instigated before obtaining the culture and sensitivity result, unless indicated clinically. The presence of nitrites in the sample is, however, much more suggestive of a bacterial infection and samples must be sent to the laboratory. In these cases, treatment with antibiotics prior to results may be warranted. Of the 100 samples tested in this study, only two had positive cultures for bacterial infection (Escherichia coli) and these were the only samples which had been strongly positive for nitrites using the Nephrur6Labsticks. These bedside screening tests may be a useful and cost-effective way of reducing the numbers of mid-stream urine samples sent to the laboratory for further testing.

The Shadow Pandemic Contextualised: Albania's Response to Domestic Violence During COVID-19.

Background: Domestic violence (DV) encompasses a pattern of psychological, physical, sexual, financial, and/or emotional abuse, manifesting through assault, threats, and intimidation. Economic and social stressors in conjunction with the COVID-19 pandemic escalated DV cases worldwide, including those in Albania. Socioeconomic vulnerabilities worsened the situation, with DV-related complaints to non-governmental organizations (NGOs) in Albania increasing by 60% between March and May 2020, compared to the same period in 2019.

Background: This article discusses the ethical issues surrounding the integration of long-acting injectable antiretroviral therapy (LA-ART) in the programmatic management of human immunodeficiency virus (HIV). As the medical landscape evolves, implementing LA-ART introduces many ethical issues that should be considered for the success of scale-up in diverse settings.
Methods: This article examines key issues such as bioethical concerns around the rollout of LA-ART, including regulatory requirements, a person's autonomy, informed consent, privacy and confidentiality; the societal implications of providing LA-ART, including the impact on stigma and discrimination; ethics around who receives LA-ART, financial accessibility, equitable access, inclusive decision-making and cultural sensitivity; and the ethics of providing an expensive intervention, including cost-effectiveness, supply chain sustainability and resource allocation.
Establishment and validation of a dual qPCR method for the detection of carbapenem-resistant in bloodstream infections.

Department of Clinical Laboratory, Guangzhou Institute of Respiratory Health, State Key Laboratory of Respiratory Disease, National Center for Respiratory Medicine, National Clinical Research Center for Respiratory Disease, Guangzhou Laboratory, The First Affiliated Hospital, Guangzhou Medical University, Guangzhou, China.
Objective: Bloodstream infections(BSIs) caused by carbapenem-resistant (CRAB) have a high mortality rate due to the high levels of drug resistance. There is an urgent need to establish a sensitive and accurate detection method to rapidly detect CRAB in BSIs.
Methods: A new method was developed based on fluorescence quantitative PCR (qPCR) targeting the specific region of 16sRNA and OXA-23 gene from CRAB.
Astrology, magic, and other psychic healing practices are undergoing a cultural revival, notably among those on the Left who employ it as a language for social justice. Queer practitioners have claimed kinship with the occult through a perceived shared abjection, deeming it an inherently queer resource for self- and community empowerment, and naming anti-racism and decolonization key aims of their work. At the same time, these forms of occultism draw suspicion, not least among practitioners themselves, who are critical of the ways these knowledge traditions have been complicit in 'spiritual genocide'.

Introduction: Bacteriocin P7 was extracted from the cell-free supernatant (CFS) of G7, which is a strain isolated from mangrove plants.
Methods: In this study, the culture conditions of G7 were optimised using an orthogonal test. The (CFS) was subsequently purified by using TA-GF75 gel chromatography, Tiderose Q HP anion chromatography and reversed-phase high-performance liquid chromatography (RP-HPLC).
