In recent years, increased knowledge about pathophysiology of primary hyperhidrosis has led to novel therapeutic advances. Topical and systemic anticholinergic agents have been proven beneficial in reducing sweat production in primary axillary hyperhidrosis (PAH), although their use is limited by the increased likelihood of systemic anticholinergic drug reactions, particularly regarding systemic agents.
This paper provides an overview of pharmaceutical characteristics, efficacy and safety data from phase II and III clinical trials on sofpironium bromide (SB), a topical anticholinergic agent that has been employed for the treatment of PAH and has already received its first approval in Japan for the treatment of PAH in the form of 5% gel formulation.
The retrometabolic drug design of topical SB presents distinct advantages, by limiting systemic absorption and therefore development of anticholinergic adverse events. This along with the popularity of the non-greasy gel formulation is expected to increase compliance. However, this therapy still offers a temporary control of PAH, compared to sympathectomy or device-based treatments, such as microwave thermolysis. Hence, physicians should balance the effectiveness against adverse events of each therapeutic modality and use a personalized approach based on patient's needs.

The coronavirus disease-2019 (COVID-19) pandemic continues to ravage the world. People living with HIV (PLHIV) are one of the most vulnerable groups. This study aims to identify the factors associated with the uptake and adverse reactions of COVID-19 vaccination.
We recruited PLHIV in China by convenience sampling between 7 and 23 February 2021. Participants were asked to complete an online questionnaire. Chi-squared test and multivariable logistic regression were used to assess factors associated with vaccine uptake.
A total of 527 vaccinated and 1091 unvaccinated PLHIV were recruited. Individuals who had a higher education, engaged in occupations with a higher risk of COVID-19 infection, received influenza or pneumonia vaccine in the past 3years (5.40, 3.36-8.77), believed in the effectiveness of vaccines (3.01, 2.20-4.12), and received media information regarding COVID-19 vaccine (2.23, 1.61-3.11), were more likely to be vaccinated. Concerning about adverse reactions (0.31, 0.22-0.44), negative impacmphasize the benefits and necessity of vaccination and provide consultancy regarding adverse reactions.
Asthma is the most common chronic respiratory disease and has been declared a global public health problem by the World Health Organization. Due to the high heterogeneity and complexity, asthma can be classified into different 'phenotypes' and it is still difficult to assess the phenotypes and stages of asthma by traditional methods. In recent years, mass spectrometry-based proteomics studies have made significant progress in sensitivity and accuracy of protein identification and quantitation, and are able to obtain differences in protein expression across samples, which provides new insights into the mechanisms and classification of asthma.
In this article, we summarize research strategies in quantitative proteomics, including labeled, label-free and targeted quantification, and highlight the advantages and disadvantages of each. In addition, new applications of quantitative proteomics and the current status of research in asthma have also been discussed. In this study, online resources such as PubMed and Google Scholar were used for literature retrieval.
The application of quantitative proteomics in asthma has an important role in identifying asthma subphenotypes, revealing potential pathogenesis and therapeutic targets. But the proteomic studies on asthma are not sufficient, as most of them are in the phase of biomarker discovery.

Retinal diseases are one of the main reasons for vision loss where all available drug treatments are based on invasive drug administration such as intravitreal injections. Despite huge efforts and some promising results in animal models, almost all delivery technologies tested have failed in human trials. There are however examples of clinically effective topical delivery systems such as fast dissolving aqueous eye drop suspensions.
Six obstacles to topical drug delivery to the eye have been identified and discussed in some details. These obstacles consist of static membrane barriers to drug permeation into the eye, dynamic barriers such as the lacrimal drainage and physiochemical barriers such as low thermodynamic activity. It is explained how and why these obstacles hamper drug permeation and how different technologies, both those that are applied in marketed drug products and those that are under investigation, have addressed these obstacles.
The reason that most topical drug delivery systems have failed to deliver therapeutic drug concentrations to the retina is that they do not address physiochemical barriers such as the thermodynamic activity of the permeating drug molecules. Topical drug delivery to the retina has only been successful when the static, dynamic, and physiochemical barriers are addressed simultaneously.

Histone deacetylases (HDACs) are epigenetic transcriptional repressors via deacetylation of histone lysines resulting in inaccessible chromatin. We reported that kidney epithelial HDAC1 and HDAC2 activity is critical for maintaining a healthy kidney and preventing fluid-electrolyte abnormalities. Aurora A Inhibitor I price However, to what extent does Hdac1/Hdac2 knockdown affect chromatin structure and subsequent transcript expression in the kidney? To answer this question, we used single nucleus assay for transposase-accessible chromatin-sequencing (snATAC-seq) and snRNA-seq to profile kidney nuclei from male and female, control, and littermate kidney epithelial Hdac1/Hdac2 knockdown mice. Hdac1/Hdac2 knockdown resulted in significant changes in the chromatin structure predominantly within the promoter region of gene loci involved in fluid-electrolyte balance such as the aquaporins, with both increased and decreased accessibility captured. Moreover, Hdac1/Hdac2 knockdown resulted different gene loci being accessible with a corresponding increased transcript number in the kidney, but among all mice only 24%-30% of chromatin accessibility agreed with transcript expression (e.g., open chromatin and increased transcript). To conclude, although chromatin structure does affect transcription, ∼70% of the differentially expressed genes cannot be explained by changes in chromatin accessibility and HDAC1/HDAC2 had a minimal effect on these global patterns. Yet, the genes that are targets of HDAC1 and HDAC2 are critically important for maintaining kidney function.
Here, we aim at describing the pattern of care, survival outcome and prognostic factors of ABC patients (pts) receiving third-line chemotherapy.
Institutional registries across three academic medical centers were retrospectively reviewed. Kaplan-Meier estimators were used to calculate survival, the log-rank test to make comparisons, and the Cox proportional hazard models to assess the progostic impact of variables.
Among 101 pts included in the analysis. 68 (67.3%), 19 (18.8%) and 14 (13.8%) had intrahepatic and extrahepatic cholangiocarcinoma and gallbladder cancer, respectively. Atotal of 63 (62.3%) pts received monochemotherapy, while 38 (37.6%) were treated with adoublet. The median OS and PFS were 5 and 3months, respectively. Disease control rate was achieved in 23 (22.7%) pts, with 2 (2%) partial responses. Grade 3-4 treatment-related adverse events were reported in 22 (21.7%) pts. At multivariate analysis, ECOG PS (p<0.001), tumor burden (p=0.01) and lymphocyte-to-monocyte ratio (p=0.02) were independent predictors of survival.
Third-line chemotherapy displayed limited activity in this real-world cohort, although prognostic factors have been identified that may assist in treatment decision. The results of this multicenter experience, highlight the need for more effective therapies and provide a benchmark for future trials in this setting.

There is limited qualitative research exploring challenges experienced following severe traumatic brain injury (TBI). We investigated challenges to recovery identified by individuals who sustained severe TBI three years earlier or their close others (COs), as well as suggestions for managing these challenges.
Nine participants with TBI and 16 COs completed semi-structured interviews. Using reflexive thematic analysis, challenges were identified across several timeframes (i.e., at the injury, acute care, inpatient rehabilitation, outpatient rehabilitation, and at home/other location).
Challenges experienced across all timeframes included lack of information and poor communication, pre-existing conditions, missed injuries, and issues with medical staff, and continuity of care. From acute care onwards, there were TBI-related consequences, issues with coping and emotional adjustment, negative outlook, insufficient treatment, lack of support for COs, and issues with compensation and funding for rehabilitatioes of individuals with traumatic brain injury and their Close Others.
Suggestions should be considered to promote successful outcomes following severe TBI.IMPLICATIONS FOR REHABILITATIONRecovery following a severe traumatic brain injury can be hindered by challenges, such as poor communication, limited information provision, injury-related consequences, limited services and emotional support for the injured individual and their Close Others, and a need for education of the broader community about traumatic brain injury.Suggestions for managing these challenges (e.g., peer supports; services closer to home) could be used to inform clinical guidelines that could be used in a rehabilitation context.These suggestions ultimately aim to improve the post-injury experience and outcomes of individuals with traumatic brain injury and their Close Others.
