Additionally, following rheological characterization, these alginate hydrogels demonstrated minimal cytotoxicity to human retinal pigment epithelial cells in vitro and exhibited injection feasibility through small-gauge needles. Our chosen MB concentrations displayed a high degree of ROS scavenging following release from the alginate hydrogels, suggesting this approach may be successful in reducing ROS levels following ON injury, or could be applied to other ocular injuries.Fluoropyrimidines (FP; 5-fluorouracil, capecitabine, and tegafur) are a commonly prescribed class of antimetabolite chemotherapies, used for various solid organ malignancies in over 2 million patients globally per annum. Dihydropyrimidine dehydrogenase (DPD), encoded by the DPYD gene, is the critical enzyme implicated in FP metabolism. DPYD variant genotypes can result in decreased DPD production, leading to the development of severe toxicities resulting in hospitalization, intensive care admission, and even death. Management of toxicity incurs financial burden on both patients and healthcare systems alike. Upfront DPYD genotyping to identify variant carriers allows an opportunity to identify patients who are at high risk to suffer from serious toxicities and allow prospective dose adjustment of FP treatment. This approach has been shown to reduce patient morbidity, as well as improve the cost-effectiveness of managing FP treatment. Upfront DPYD genotyping has been recently endorsed by several countries in Europe and the United Kingdom. This review summarizes current knowledge about DPD deficiency and upfront DPYD genotyping, including clinical and cost-effectiveness outcomes, with the intent of supporting implementation of an upfront DPYD genotyping service with individualized dose-personalization.
Patient-provider communication is a major barrier to care, with some providers giving their personal phone number (PPN) to patients for increased accessibility. We investigated participant utilization of provider's PPN, its effect on participant satisfaction, provider's ability to predict abuse of this practice, and evolving provider perceptions.
Prospective, randomized study.
Single institution, tertiary referral center.
During a 2-week period, otolaryngology patients were randomized to either receive their provider's PPN or not. Providers predicted the likelihood of abuse. All calls/texts were documented for 4 weeks. At the study's conclusion, participants were surveyed using Press Ganey metrics. Providers were surveyed before and after to assess their likelihood of providing patients with their PPN and its impact on work demands.
Of the 507 participants enrolled, 266 were randomized to the phone number group (+PN). Of 44 calls/texts from 24 participants, 8 were considered inappropriate. Ten participants were predicted to abuse the PPN, but only one was accurately identified. Participants in the +PN group had a greater mean composite satisfaction score than the control group (4.8 vs 4.3; Welch's
-test,
< .0011). At the conclusion of the study, providers were more likely to share their PPN (Wilcoxon signed-rank test,
< .0313), and their perceived impact of this practice on workload was lower (Wilcoxon signed-rank test,
< .0469).
This study demonstrates low patient utilization of provider PPNs, and poor provider predictive ability of patient abuse. Receipt of provider's PPN was associated with improved patient satisfaction.

The current study aimed to identify patients presenting with acute pain who may be at risk for a complicated trajectory, via identifying clusters of early opioid prescribing patterns.
National Veterans Affairs administrative data were utilized to build a cohort of outpatients with acute pain presentations and no more than minimal opioid use in the prior year. Latent Class Analyses (LCAs) identified clusters of early opioid prescribing patterns. The risk of progression to long-term opioid use was contrasted between LCA clusters using log-binomial regression, adjusting for confounding variables.
The 2018 cohort included N=191,283. Among the 27,890 who received an initial opioid prescription, LCA classes were identified using first supply day, total days dispensed across 30 days, opioid type, dose and number of prescriptions across the first 30 days. In the three-class model class 1 indicated an immediate, low-dose and brief supply; class 2 included delayed, low-dose and longer duration prescriptions and class 3 included delayed, high-dose and moderate duration prescriptions. Adjusted relative risk ratios for progression to long-term opioid use in the following year were 3.33 (95% CI 2.71-4.10) for class 1 (absolute risk 1.1%); 7.76 (95% CI 6.69-8.99) for class 2 (3.1%) and 6.81 (95% CI 5.72-8.12) for class 3 (2.4%) compared to patients who did not receive an acute opioid prescription (0.3%).
These clusters of acute opioid prescribing could facilitate the identification of patients who may benefit from enhanced pain care earlier in the pain trajectory and decrease future reliance on long-term opioid therapy.

Nontuberculous mycobacteria are environmental organisms that cause infections leading to chronic, debilitating pulmonary disease, among which Mycobacterium avium complex (MAC) is the most common species.
We described patterns of macrolide-based multi-drug antibiotic therapies for MAC pulmonary disease (MAC-PD) in U.S. Medicare beneficiaries with bronchiectasis between January 2006 and December 2014. MAC therapy was defined as a multi-drug regimen containing a macrolide plus ≥1 other drug targeting MAC-PD (rifamycin, ethambutol, fluoroquinolone, or amikacin) prescribed concomitantly for >28 days.
We identified 9,189 new MAC therapy users, who were mean 74 years of age (s.d. = 6) at therapy start, 75% female and 87% non-Hispanic white. A guideline-based regimen (macrolide, ethambutol and rifamycin +/- amikacin) was prescribed for 51% of new MAC therapy users at treatment start, of which 41% were continuing guideline-based therapy at 6 months, and only 18% at 12 months. Of all new MAC therapy users, by atment patterns for MAC-PD among older U.S. populations. Future research should examine treatment patterns using more contemporary data sources.
Color imaging is a tried and true method for the evaluation of cosmetic and dermatological effects, but it fails to capture all the information in a scene's spectral reflectance. For this reason, there has been in recent years increasing interest in the use of imaging spectrometers for clinical studies and product evaluation.
We developed a novel HyperSpectral Imager (HSI) able to take in vivo full-face format images as a next generation instrument for skin color measurement and beyond. Here, we report part of the results of our first full-scale validation test of the HSI. We replicated a make-up foundation screening test by applying three products to a panel of 9 models and evaluated the product L
, a
, b
, and ∆E effect immediately after application relative to the bare skin condition. We repeated this test twice in order to study the repeatability of the HSI as an evaluation instrument and during each test two different operators duplicated the data acquisition so we can assess the reproducibilitt also that it gives operational advantages over the previous generation of evaluation instruments, as it provides a spectral measurement combined with good spatial resolution. This allows for analysis of color over an area and post hoc selection of study regions and so opens new possibilities for studies of complex in vivo phenomena which neither non-imaging spectrometers nor conventional cameras can pursue. This study also raises points for future work concerning proper inclusion of instrument uncertainty in comparisons of results between instruments and handling of systematic uncertainties from analyses based on a single area.The COVID-19 pandemic has aggravated the obstacles for HIV/AIDS programs in limited-resource countries like Vietnam to achieve the HIV/AIDS-related Sustainable Development target. The paper aims to evaluate the impact of the COVID-19 pandemic on the provision of HIV/AIDS services-a pathway to achieving universal health coverage for key populations (KPs). LL37 Employing mix-methods, we conducted a desk study, one focus group discussion, and ten in-depth interviews with participants from the Ministry of Health, Provincial Centres for Disease Control, and HIV/AIDS-related facilities. The results showed the reduced coverage of KPs with access to prevention (i.e., harm-reduction services, counselling), testing, and treatment services (i.e., antiretroviral therapy, isoniazid preventive therapy). It also showed the reduced coverage of quality essential services, mainly in skipping consultation and testing, delaying un-emergency services, and redirecting KPs to non-HIV-specialised facilities. There was a gap in providing support for mental health, violence/abuse, and reproductive health. Financial risk protection for KPs was reduced due to uncertain local budget allocation; decreasing their ability to pay for HIV/AIDS-related services and social health insurance premiums; and increased out-of-pocket payments to comply with the COVID-19 control measures. This paper provides recommendations for strategic planning to ensure universal health coverage for KPs in the post COVID-19 era, especially for limited-resource countries like Vietnam.The use of light for therapeutic purposes dates back to ancient Egypt, where the sun itself was an innovative source, probably used for the first time to heal skin diseases. Since then, technical innovation and advancement in medical sciences have produced newer and more sophisticated solutions for light-emitting sources and their applications in medicine. Starting from a brief historical introduction, the concept of innovation in light sources is discussed and analysed, first from a technical point of view and then in the light of their fitness to improve existing therapeutic protocols or propose new ones. If it is true that a "pure" technical advancement is a good reason for innovation, only a sub-system of those advancements is innovative for phototherapy. To illustrate this concept, the most representative examples of innovative light sources are presented and discussed, both from a technical point of view and from the perspective of their diffusion and applications in the clinical field.Caesarean section (C-section) rates continue to rise globally. Yet, there is little consensus about the key determinants of rising C-section rates and the sources of variation in C-section rates across the world. While C-sections can save lives when medically justified, unnecessary surgical procedures can be harmful for women and babies. We show that a state-wide law passed in São Paulo (Brazil), which increased women's autonomy to choose to deliver via C-section even when not medically necessary, is associated with a 3% increase in overall C-section rates. This association was driven by a 5% increase in primary C-sections, rather than repeated C-sections. Since the law emphasizes women's autonomy, these results are consistent with mothers' demand being an important contributor to high C-section rates in this context.
