Biosimilars offer the potential for cost savings and expanded access to biologic products; however, there are concerns regarding the rate of biosimilar uptake. We assessed the relationship between biosimilar and originator pricing, coverage, and market share by describing four case studies that fall into two categories: (1) sole preferred coverage strategy (ie, aim is to have originator product preferred; biosimilar(s) non-preferred), defined as steep average sales price (ASP) reductions for originator products (decline in net prices by at least 50% following the introduction of biosimilar competition by 2022) and (2) non-sole preferred coverage strategy (ie, aim is to have originator product preferred alongside biosimilar products), defined as moderate ASP reductions for originator products with (net prices did not decline by at least 50% of its pre-biosimilar competition value). We found that originators with sole preferred coverage strategies maintained formulary preference and market share relative to originators with non-sole preferred coverage strategies. Regardless of strategy, the market-weighted ASP for all four product families (originator and biosimilars) declined significantly in the years following the introduction of biosimilars, suggesting that biosimilar uptake alone may not be a complete measure of whether the biosimilar market is facilitating competition and lowering prices.

HIV-1 has an antisense gene overlapping env that encodes the ASP protein. ASP functions are still unknown, but it has been associated with gp120 in the viral envelope and membrane of infected cells, making it a potential target for immune response. Despite this, immune response patterns against ASP are poorly described and can be influenced by the high genetic variability of the env gene. To explore this, we analyzed 100k HIV-1 ASP sequences from the Los Alamos HIV sequence database using phylogenetic, Shannon entropy (Hs), and logo tools to study ASP variability in worldwide and Brazilian sequences from the most prevalent HIV-1 subtypes in Brazil (B, C, and F1). Data obtained in silico guided the design and synthesis of 15-mer overlapping peptides through spot synthesis on cellulose membranes. Peptide arrays were screened to assess IgG and IgM responses in pooled plasma samples from HIV controllers and individuals with acute or recent HIV infection. Excluding regions with low alignment accuracy, several sites with higher variability (Hs > 1.5) were identified among the datasets (25 for worldwide sequences, 20 for Brazilian sequences). Among sites with Hs < 1.5, sequence logos allowed the identification of 23 other sites with subtype-specific signatures. Altogether, amino acid variations with frequencies > 20% in the 48 variable sites identified were included in 92 peptides, divided into 15 sets, representing near full-length ASP. During the immune screening, the strongest responses were observed in three sets, one in the middle and one at the C-terminus of the protein. While some sets presented variations potentially associated with epitope displacement between IgG and IgM targets and subtype-specific signatures appeared to impact the level of response for some peptides, signals of cross-reactivity were observed for some sets despite the presence of B/C/F1 signatures. Our data provides a map of ASP regions preferentially targeted by IgG and IgM responses. Despite B/C/F1 subtype signatures in ASP, the amino acid variation in some areas preferentially targeted by IgM and IgG did not negatively impact the response against regions with higher immunogenicity.

UNASSIGNED: Earlier reports suggested high rates of antibiotic utilization among COVID-19 patients despite the lack of direct evidence of their activity against viral pathogens. Different trends in antibiotic consumption during 2020 compared to 2019 have been reported.
UNASSIGNED: The objective of this study is to assess the impact of COVID-19 pandemic on antibiotic consumption in the presence of active Antibiotic Stewardship Program.
UNASSIGNED: This study represented a five years assessment of the consumption of the commonly prescribed antibiotics measured as DDDs/100-Bed Days. We analyzed the data by using nonparametric Friedman and Friedman tests to compare the antibiotic consumption before and during the three subsequent waves of COVID-19.
UNASSIGNED: Antibiotic consumption through the DDDs/100-BD has shown reduction in the median of antibiotics consumption of most antibiotics during the period of COVID-19 as compared to the pre-COVID-19 period, which was significant for meropenem and ciprofloxacin, except colomycin that slightly increased. Significant reduction in the consumption of imipenem and meropenem during the second and third waves as compared to the pre-COVID period. Throughout the years, significant reductions were observed between 2018 and 2019 (p=<.001), 2018 and 2020 (p=0.008), and 2018 and 2022 (p=0.002).
UNASSIGNED: The reduction in antibiotic consumption is attributed to the strong influence if the ASP and the reluctance of people to visit hospitals during the COVID-19 pandemic. Other related COVID-19 precautions such as physical distance, good hand hygiene, facemasks, that resulted in the prevention of secondary bacterial infections have contributed to the reduction in antibiotic utilization during the pandemic.

Nonhuman primate species currently face human-induced pressures and will continue to face them in the modern landscape. These pressures require conservation projects in primate habitat countries to aid in protection, preservation, and conservation. Though there are several examples of primate conservation projects, starting up an initiative can be a daunting task. The American Society of Primatology (ASP) Conservation Committee hosted a video webinar presenting on the first steps of developing, running and continuing a primate conservation program. Dr. Christopher Shaffer, Rahayu Oktaviani, and Dr. Jill Pruetz presented their early program experiences establishing wild primate conservation projects to educate primatologists around the world. The running themes of the presentations included establishing community, working locally, impacting locally and preparing for the future.

The escalating challenge of antimicrobial resistance (AMR) poses a considerable concern for global health, particularly impacting low- and middle-income countries (LMICs). This article highlights the critical importance of tackling AMR in LMICs by adopting the Global Antimicrobial Stewardship Accreditation Scheme (GAMSAS). GAMSAS is portrayed as a holistic and sustainable strategy for antimicrobial stewardship, extending beyond accreditation to include educational programs, capacity enhancement, improved surveillance, and support for AMS policy research. While acknowledging the global uptake of the scheme, the article highlights its preliminary phase of adoption in LMICs, particularly in high-AMR burden regions like Sub-Saharan Africa. The piece stresses the imperative for LMICs to integrate GAMSAS, underscoring its significance in optimizing antimicrobial usage and patient health outcomes. It advocates for an all-encompassing approach that leverages international cooperation and sustained financial backing, crucial for the effective deployment and enduring success of antimicrobial stewardship efforts in these key areas.

Introduction: Growing antimicrobial resistance (AMR) and decreasing efficacy of the available antimicrobials have become a significant public health concern. The antimicrobial stewardship program (ASP) ensures the appropriate use of antimicrobials and mitigates resistance prevalence through various interventions. One of the core components of the ASP is to educate healthcare workers (HWs). Therefore, this study aims to identify the impact of a pharmacist-led educational intervention targeting knowledge, attitude, and practices regarding rational antibiotic use among healthcare professionals in a secondary care hospital in Punjab. Methods: This is a single-center, questionnaire-based, pre-post interventional study conducted over a six-month time period. Data analysis was conducted using SPSS version 26. Results: Regarding the pre-interventional knowledge, attitude, and practice (KAP) score of the respondents, 90.3% had a good knowledge score, 81.5% had a positive attitude, and 72.3% of HWs (excluding doctors) had a good practice score. Additionally, 74.6% of the doctors had a good practice score. After educational intervention, there was a significant improvement in the knowledge, attitude, and practice of the respondent HWs (p-value <0.001). Furthermore, males have higher knowledge scores compared to females in the pre- and post-intervention stages (p-value <0.05), and doctors differ from nurses regarding knowledge scores in both pre- and post-intervention stages. Conclusion: Considering educational programs as the backbone of the ASP, it is imperative to sustain efforts in the ongoing educational programs of HWs to foster high awareness and adherence to the ASP among HWs.

Adipose tissue, as an endocrine organ, secretes several adipocyte-derived hormones named \'adipokines\' that are implicated in regulating energy haemostasis. Substantial evidence shows that white adipose tissue-derived adipokines mediate the link between obesity-related exogenous factors (like diet and lifestyle) and various biological events (such as pre- and postmenopausal status) that have obesity consequences (cardiometabolic disorders). One of the critical aetiological factors for obesity-related diseases is the dysfunction of adipokine pathways. Acylation-stimulating protein (ASP) is an adipokine that stimulates triglyceride synthesis and storage in adipose tissue by enhancing glucose and fatty acid uptake. ASP acts via its receptor C5L2. The primary objective of this review is to address the existing gap in the literature regarding ASP by investigating its diverse responses and receptor interactions across multiple determinants of obesity. These determinants include diet composition, metabolic disorders, organ involvement, sex and sex hormone levels. Furthermore, this article explores the broader paradigm shift from solely focusing on adipose tissue mass, which contributes to obesity, to considering the broader implications of adipose tissue function. Additionally, we raise a critical question concerning the clinical relevance of the insights gained from this review, both in terms of potential therapeutic interventions targeting ASP and in the context of preventing obesity-related conditions, highlighting the potential of the ASP-C5L2 interaction as a pharmacological target. In conclusion, these findings validate that obesity is a low-grade inflammatory status with multiorgan involvement and sex differences, demonstrating dynamic interactions between immune and metabolic response determinants.

This paper introduces a comprehensive framework that elucidates the microfoundations of data-driven antimicrobial stewardship programs (ASPs), specifically focusing on resource-constrained settings. Such settings necessitate the utilization of available resources and engagement among multiple stakeholders. The microfoundations are conceptualized as interlinked components: input, process, output, and outcome. Collectively, these components provide a comprehensive framework for understanding the development and implementation of data-driven ASPs in resource-constrained settings. It underscores the importance of considering both the social and material dimensions when evaluating microbiological, clinical, and social impacts. By harmonizing technology, practices, values, and behaviors, this framework offers valuable insights for the development, implementation, and assessment of ASPs tailored to resource-constrained environments.

In growing plant population, effect of stress is a perturb issue affecting its physiological, biochemical, yield loss and developmental growth. Protein-L-isoaspartate-O-methyltransferase (PIMT) is a broadly distributed protein repair enzyme which actuate under stressful environment or aging. Stress can mediate damage converting protein bound aspartate (Asp) residues to isoaspartate (iso-Asp). This spontaneous and deleterious conversion occurs at an elevated state of stress and aging. Iso-Asp formation is associated with protein inactivation and compromised cellular survival. PIMT can convert iso-Asp back to Asp, thus repairing and contributing to cellular survival. The present work describes the isolation, cloning, sequencing and expression of PIMT genes of Carica papaya (Cp pimt) and Ricinus communis (Rc pimt) Using gene specific primers, both the pimts were amplified from their respective cDNAs and subsequently cloned in prokaryotic expression vector pProEXHTa. BL21(DE3) strain of E. coli cells were used as expression host. The expression kinetics of both the PIMTs were studied with various concentrations of IPTG and at different time points. Finally, the PIMT supplemented BL21(DE3) cells were evaluated against different stresses in comparison to their counterparts with the empty vector control.

BACKGROUND: The concerning growth of antimicrobial resistance (AMR) renders common infections life-threatening due to irrational antibiotic use and a lack of effective antimicrobial stewardship programmes (ASPs).
OBJECTIVE: To investigate the awareness, perceptions and practices of physicians regarding ASPs, AMR and antibiotic prescribing in tertiary care hospitals in Bangladesh.
METHODS: This hospital-based cross-sectional survey was conducted in 11 tertiary care hospitals across Bangladesh between September 2020 and January 2021. A semi-structured questionnaire was administered through face-to-face interviews for data collection. Descriptive and multi-variate analyses were performed using STATA Version 13.
RESULTS: In total, 559 physicians were enrolled in this survey. Overall, 40.6% [95% confidence interval (CI) 36.5-44.8] of physicians reported being aware of ASPs, and this figure was higher in public hospitals compared with private hospitals (43.8% vs 27.1%). None of the study hospitals had any ASP initiatives. More than half (55.1%) of the participants were willing to receive feedback from an ASP on their antibiotic selection. Only 30.9% of respondents stated that they wait for the findings of microbiological tests before prescribing antibiotics, although challenges included empiric use of broad-spectrum antibiotics, delayed laboratory results and the existence of drug-resistant patients. In contrast, physicians aware of ASPs were 33% (adjusted odds ratio 0.67, 95% CI 0.45-0.98; P=0.033) less likely to wait for laboratory results before prescribing antibiotics. However, 42.5% of physicians considered patient affordability of purchasing antibiotics when prescribing.
CONCLUSIONS: Physicians\' fundamental knowledge of ASPs and rational antibiotic prescription were found to fall short of the standard. Context-specific and integrated ASP activities, availability and use of guidelines, and improved laboratory facilities are required to battle AMR in Bangladesh.
