Coronavirus disease has disrupted tuberculosis services globally. Data from 33 centers in 16 countries on 5 continents showed that attendance at tuberculosis centers was lower during the first 4 months of the pandemic in 2020 than for the same period in 2019. Resources are needed to ensure tuberculosis care continuity during the pandemic.

Retinoid X receptors (RXRs) present a subgroup of the nuclear receptor superfamily with particularly high evolutionary conservation of ligand binding domain. The receptor exists in α, β, and γ isotypes that form homo-/heterodimeric complexes with other permissive and non-permissive receptors. While research has identified the biochemical roles of several nuclear receptor family members, the roles of RXRs in various neurological disorders remain relatively under-investigated. RXR acts as ligand-regulated transcription factor, modulating the expression of genes that plays a critical role in mediating several developmental, metabolic, and biochemical processes. Cumulative evidence indicates that abnormal RXR signalling affects neuronal stress and neuroinflammatory networks in several neuropathological conditions. Protective effects of targeting RXRs through pharmacological ligands have been established in various cell and animal models of neuronal injury including Alzheimer disease, Parkinson disease, glaucoma, multiple sclerosis, and stroke. This review summarises the existing knowledge about the roles of RXR, its interacting partners, and ligands in CNS disorders. Future research will determine the importance of structural and functional heterogeneity amongst various RXR isotypes as well as elucidate functional links between RXR homo- or heterodimers and specific physiological conditions to increase drug targeting efficiency in pathological conditions.

The rhizomes of ginger have been in use in many forms of traditional and alternative medicines. Besides being employed as condiment and flavoring agent, it is used in the treatment of nausea, osteoarthritis, muscle pain, menstrual pain, chronic indigestion, Alzheimer’s disease, and cancer. Ginger rhizome contains volatile oils, phenolic compounds and resins, and characterization studies showed that [6]-gingerol, [6]-shogaol, and [6]-paradol are reported to be the pharmacologically active components. Gingerol is a major chemical constituent found as volatile oil in the rhizomes of ginger. It has several medicinal benefits and used for the treatment of rheumatoid arthritis, nausea, cancer, and diabetes. Many studies have been carried out in various parts of the world to isolate and standardize gingerol for their use as a complementary medicine. The present review summarizes wide range of research studies on gingerol and its pharmacological roles in various metabolic diseases. Graphical Abstract

The study shows that deposition of amyloid-β plaques leads to thickening of the retina with subsequently reduced light responses of retinal ganglion cells (measured with multielectrode-array recording), which is observed to occur before deterioration in cognitive behavior. [...]the potential of in vivo retinal fundus imaging using OCT to non-invasively evaluate vascular and structural changes along with the alterations of oxygen metabolism can be used to assess multiple sclerosis (MS)-related retinal pathology as shown by Kallab et al. [...]advancements in clinical and lab-based imaging equipment offer easy evaluation of structural, functional, and vascular changes in the retina.

The Human Proteome Project (HPP) aims to discover high-stringency data for all proteins encoded by the human genome. Currently, ∼18% of the proteins in the human proteome (the missing proteins) do not have high-stringency evidence (for example, mass spectrometry) confirming their existence, while much additional information is available about many of these missing proteins. Here, we present MissingProteinPedia as a community resource to accelerate the discovery and understanding of these missing proteins. The Human Proteome Project aims to catalogue the ∼20,000 proteins encoded by the human genome. In this review, Baker et al . focus on the missing proteins, proteins that lack high stringency proteomic evidence, and launch MissingProteinPedia, a database aimed at accelerating the search for missing proteins.

Antimicrobial resistance (AMR) is usually framed as a technical problem of drug-resistant pathogens, yet for those living with it, AMR is an everyday condition of uncertainty that reshapes what it means to remain alive, treatable, and connected to health systems. This article develops a fluid onto-epistemology of human existence in the presence of AMR, asking how existence, risk and knowledge are co-produced across Thailand’s AMR landscape. First, it traces how AMR emerges from ordinary practices and infrastructures – from prescribing, dispensing and surveillance to water, sanitation and food systems – to conceptualise AMR as a slow-onset, super-wicked disaster nested within human lives rather than external to human existence. Second, it examines how human lives are valued, protected or left at risk within Thailand’s evolving AMR governance, including tensions between national indicators, everyday therapeutic practices and the position of refugees and migrants at the margins of entitlement. Third, it proposes a communicative-ecology lens for mapping how knowledge of AMR moves between actors, institutions and environments, and how these flows shape possibilities for anticipation, care and accountability. The resulting framework is designed to be transferable and empirically usable: it can be populated with quantitative and qualitative data, scaled between national profiles and local settings, and adapted as stakeholder configurations change. In the Thai context, this means reading AMR as part of the country’s disaster risk profile, especially in refugee- and migrant-affected settings where surveillance is challenging. Future research on AMR in Thailand – including along the Thai-Myanmar border and in refugee- and migrant-affected settings will collect and interpret data through this framework in order to better align everyday experiences of risk with policy, surveillance and intervention.

Neuropeptide Y (NPY), a sympathetic neurotransmitter, is involved in various physiological functions, and its dysregulation is implicated in several neurodegenerative diseases. Glutamate excitotoxicity, endoplasmic reticulum (ER) stress, and oxidative stress are the common mechanisms associated with numerous neurodegenerative illnesses. The present study aimed to elucidate the protective effects of NPY against glutamate toxicity and tunicamycin-induced ER stress in the human neuroblastoma SH-SY5Y cell line. We exposed the SH-SY5Y cells to glutamate and tunicamycin for two different time points and analyzed the protective effects of NPY at different concentrations. The protective effects of NPY treatments were assessed by cell viability assay, and the signalling pathway changes were evaluated by biochemical techniques such as Western blotting and immunofluorescence assays. Our results showed that treatment of SH-SY5Y cells with NPY significantly increased the viability of the cells in both glutamate toxicity and ER stress conditions. NPY treatments significantly attenuated the glutamate-induced pro-apoptotic activation of ERK1/2 and JNK/BAD pathways. The protective effects of NPY were further evident against tunicamycin-induced ER stress. NPY treatments significantly suppressed the ER stress activation by downregulating BiP, phospho-eIF2α, and CHOP expression. In addition, NPY alleviated the Akt/FoxO3a pathway in acute oxidative conditions caused by glutamate and tunicamycin in SH-SY5Y cells. Our results demonstrated that NPY is neuroprotective against glutamate-induced cell toxicity and tunicamycin-induced ER stress through anti-apoptotic actions.

Background: Antimicrobial resistance (AMR), a major threat to global public health, can be addressed using a managed care approach. This includes timely analysis of antibiotic consumption and procurement data to drive evidence-based policies and practices in healthcare facilities. ‘ABC analysis’ presents an opportunity for this.Methods: ABC analysis data for a comprehensive Primary Health Care (PHC) clinic in the Eastern Cape province of South Africa was obtained from the Provincial Department of Health for 01 April 2015 to 31 March 2018. Procured antibiotics were analysed on the quantities purchased, total cost, route of administration and spectrum of activity. Antibiotic categorization was also carried out according to the World Health Organization Model List of Essential Medicines (WHO EML) 2017.Results: Antibiotics made up approximately 7% of the total annual pharmaceutical expenditure. A total of 31, 35 and 34 antibiotics were procured in the first, second and third years, respectively. The most procured antibiotics were: (1) isoniazid, (2) flucloxacillin, (3) azithromycin, (4) a combination of rifampicin, isoniazid, pyrazinamide, and ethambutol and (5) amoxicillin. Overall, 55%, 2% and 15% of antibiotics accounted for the ‘Access’, ‘Watch’ and ‘Access and Watch’ categories, respectively, of the WHO EML. No ‘Reserve’ antibiotics were procured. The remaining 28% were antituberculosis medicines. Altogether, 89%, 8% and 3% of the antibiotics were respectively administered orally, systemically, and topically. A total of 58% were broad-spectrum and 42% were narrow-spectrum antibiotics.Conclusion: Oral antibiotics in the ‘Access’ category presented favourable usage of antibiotics. Decreasing the use of broad-spectrum antibiotics requires consideration.
