JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY. B, BIOLOGY 2024; 252:112862. [PMID: 38330691 DOI: 10.1016/j.jphotobiol.2024.112862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 01/23/2024] [Accepted: 02/02/2024] [Indexed: 02/10/2024]
Abstract
Catharanthus roseus produces a large array of terpenoid indole alkaloids (TIAs) that are important natural source for many drugs. Ultraviolet B (UVB) radiation have been proved to have regulatory effect towards biosynthesis of TIAs, which were meaningful for boost of TIA production. To decipher more comprehensive molecular characteristics in C. roseus under UVB radiation, integrated analysis of the nuclear proteome together with the transcriptome data under UVB radiation were performed. Expression of genes related to transmembrane transporters gradually increased during the prolonged exposure to UVB radiation. Some of known TIA transporters were affected by UVB. Abundance of proteins associated with spliceosome and nucleocytoplasmic transport increased. Homologs belonging to ORCA and CrWRKY transcription factors family increased at both transcriptomic and proteomic levels. At the same time, the numbers of differential alternative splicing events between UVB-radiated and white-light-treated plants continuously increased. These results suggest that the nucleus participated in early response of C. roseus under UVB radiation, where alternative splicing events occurred and might regulate multiple pathways. Furthermore, integrative omics analysis indicates that expression of enzymes at the terminal stages of seco-iridoid pathway decreased with the prolonged radiation exposure, potentially inhibiting further rise of TIA synthesis under extended UVB exposure.

Abstract
OBJECTIVES The study estimated the shortages of oncology medicines in Pakistan, their causes, impacts, mitigation strategies, and possible interventions. DESIGN Cross-sectional survey. SETTING Oncology pharmacists working at 43 oncology settings (out of 80) from five regions of Pakistan (four provinces (Punjab, Sindh, Khyber Pakhtunkhwa and Baluchistan) and one federal territory (Islamabad)) were approached. PARTICIPANTS Oncology pharmacists with more than 1 year of experience were selected using stratified random sampling, and data were collected using a questionnaire from September 2021 to January 2022. PRIMARY AND SECONDARY OUTCOME MEASURES To estimate the prevalence of oncology medicine shortages in Pakistan and establish recommendations to overcome them. RESULTS Of 167 responded pharmacists, 87% experienced shortages in their practice. Most respondents (50%) experienced both oncology and support agent shortages. It was a current problem in hospitals (58%) and increased with time, but the situation varied across regions (p=0.007). Mainly shortages occur half-yearly (p=0.001) and last for <3 months. Injectable (56.8%) and branded drugs (44.9%) were short. The most frequently mentioned drugs affected by shortages were etoposide, paclitaxel, dacarbazine, bleomycin and carboplatin. Usually, distributors (51.5%) notify the pharmacists about the shortages, and federal agencies (36%) are responsible for these shortages. Distributors (53.4%) were the main source of supply, and shortages were encountered by them as well. The impacts included delayed care (25%) and suboptimal outcomes (23%) on patients, extra time (32%) for staff, prioritisation issues (31%) for pharmacists, delayed clinical trials (60.5%) and increased drugs prices (52.1%). Some hospitals have reporting systems (39.5%) and recording (29.3%) drug shortages. The shortages were managed using available alternative options (21%) and redistributing (21%) the currently available stock. CONCLUSION Pakistan's healthcare system is affected by oncology medicine shortages. The government should establish a cancer registry and drug shortage platform, revise drug prescribing/pricing policies and practice penalties for breaching regulations. Oncology medicines must be widely available to avoid the grey market.

Abstract
Monoterpene indole alkaloids (MIAs) encompass a diverse family of over 3000 plant natural products with a wide range of medical applications. Further utilizations of these compounds, however, are hampered due to low levels of abundance in their natural sources, causing difficult isolation and complex multi-steps in uneconomical chemical syntheses. Metabolic engineering of MIA biosynthesis in heterologous hosts is attractive, particularly for increasing the yield of natural products of interest and expanding their chemical diversity. Here, we review recent advances and strategies which have been adopted to engineer microbial and plant systems for the purpose of generating MIAs and discuss the current issues and future developments of manufacturing MIAs by synthetic biology approaches.

Abstract
INTRODUCTION Current research to assess the impact that medicine shortages have on patients is limited to general aspects, such as the prevalence of shortages and product characteristics. The aim of this study is to assess the overall impact that medicine shortages have on economic, clinical, and humanistic outcomes. METHODS A cohort of all known products in shortage in the Netherlands between 2012 and 2015 were characterized by their route of administration, anatomical therapeutic chemical class, and whether they were originator or generic products. A representative sample of 324 shortages (18% of all shortages) was rated as having low, medium, or high impact on the five elements that determine the impact of shortages on patients: availability of an alternative product, underlying disease, susceptibility of the patient, costs (for patients and society at large), and number of patients affected. Ratings were converted into numerical scores per element and multiplied to obtain an overall impact score. RESULTS Two elements were most frequently rated as having a high impact: disease (29%) and costs (20%). Nearly half of the shortages (47%) rated high on at least one element, while nearly 10% rated high on multiple elements. Thirty percent of the shortages rated high on direct impact, which is represented by these elements: alternative product and disease. An additional 17% of the shortages rated high on indirect impact, which is represented by these elements: costs, susceptibility, and number of patients. High impact scores could not significantly be attributed to characteristics of the products in shortage. CONCLUSIONS An assessment of the medicine shortages' impact using a framework based on economic, clinical, and economic outcomes showed that all three outcomes affect the overall impact that medicine shortages have on patients.

Abstract
This study aimed to examine the current situation of anti-cancer drug shortages in Pakistan, namely its determinants, impacts, adopted mitigation strategies, and proposed solutions. Qualitative semi-structured, in-depth interviews were conducted with 25 pharmacists in oncology hospitals in Pakistan from August to October 2021. Data were collected in person and online, recorded, and subjected to inductive thematic analysis after being transcribed verbatim. Most participants experienced anti-cancer drug shortages that increased during the pandemic. Etoposide, paclitaxel, vincristine, dacarbazine, and methotrexate were frequently short. Important causes included the compromised role of regulatory authorities, lack of local production, and inventory mismanagement. The impacts were delayed/suboptimal treatment and out-of-pocket costs for patients, patients' prioritization, increased workload, negative work environment, and patients' trust issues for pharmacists. The participants proposed that a cautious regulator's role is needed to revise policies for all stakeholders and support all stakeholders financially at their level to increase access to these medicines. Based on the outcomes, it is clear that anti-cancer medicine shortages are a current issue in Pakistan. Governmental authorities need to play a role in revising policies for all levels of the drug supply chain and promoting local production of these drugs. Stakeholders should also collaborate and manage inventory.

Abstract
Monoterpene indole alkaloids (MIAs) are a diverse family of complex plant secondary metabolites with many medicinal properties, including the essential anti-cancer therapeutics vinblastine and vincristine1. As MIAs are difficult to chemically synthesize, the world’s supply chain for vinblastine relies on low-yielding extraction and purification of the precursors vindoline and catharanthine from the plant Catharanthus roseus, which is then followed by simple in vitro chemical coupling and reduction to form vinblastine at an industrial scale2,3. Here, we demonstrate the de novo microbial biosynthesis of vindoline and catharanthine using a highly engineered yeast, and in vitro chemical coupling to vinblastine. The study showcases a very long biosynthetic pathway refactored into a microbial cell factory, including 30 enzymatic steps beyond the yeast native metabolites geranyl pyrophosphate and tryptophan to catharanthine and vindoline. In total, 56 genetic edits were performed, including expression of 34 heterologous genes from plants, as well as deletions, knock-downs and overexpression of ten yeast genes to improve precursor supplies towards de novo production of catharanthine and vindoline, from which semisynthesis to vinblastine occurs. As the vinblastine pathway is one of the longest MIA biosynthetic pathways, this study positions yeast as a scalable platform to produce more than 3,000 natural MIAs and a virtually infinite number of new-to-nature analogues. De novo microbial biosynthesis of vindoline and catharanthine using a highly engineered yeast and in vitro chemical coupling to vinblastine is carried out, positioning yeast as a scalable platform to produce many monoterpene indole alkaloids.

Abstract
OBJECTIVE Anti-cancer medicine shortages are advancing challenges for patients and hospitals. This study aims to evaluate anti-cancer and supportive medicine shortages in a tertiary hospital in Pakistan and propose solutions. METHOD A retrospective observational research was performed in a tertiary care hospital in Pakistan from 2016 to 2020. Data was retrieved from the hospital database using a questionnaire regarding short medicines' generic name, brand, dosage, source, total source, frequency, causes, impact, management, and analyzed by Microsoft Excel 2013. RESULTS Between January 2016 and December 2020, 43 individual medicine shortages were observed, with an average of 8.6 shortages per year. There were shortages of 22 medicines, including 8 anti-cancer (36.4%) and 14 supportive agents (63.6%). Total shortage days were 27,100, with an average of 1232 days (SD 757) per medicine. Supportive medicines' shortages were frequent, but oncology agents' shortages were constant. The most affected dosage form was injection. Cardiovascular drugs and alkylating agents were the most affected class in supportive and anti-cancer medicines, respectively. The use of "alternative medicine" and "patient needs based importation" were the most common mitigation strategies. CONCLUSION Shortages of oncology medicines are challenging in Pakistan. The most prominent causes are the lack of updated governmental regulations, registration, and import issues. The tertiary care hospital has very few sources of supply, so it imports these drugs on a need basis to manage the shortages. But it is still concerning because of the huge financial burden on patients and institutions due to expensive import, and therapy become delayed as the import process takes time. Moreover, the most affected drug class was alkylating agents, and dosage was both injectable and oral medicines.

Abstract
PURPOSE Drug shortages are a clear and growing challenge. Prominent shortages included oncology medications and supportive care products essential for the care of patients with cancer. Oncology drug shortages often result in disruptions in the timing of chemotherapy treatments, alterations in the dose or regimen administered, or even missed doses when alternative agents are unavailable. The purpose of this survey was to characterize the impact of oncology drug shortages across the United States, including the experiences of health care organizations, resource implications, and the impact on patient safety, patient care, and clinical trials. METHODS A 36-item online survey was distributed to membership of the Hematology/Oncology Pharmacy Association to gather information on shortages of oncology drugs (ie, all drugs essential in the care of patients with cancer, including supportive care agents). RESULTS Sixty-eight US organizations participated in the survey between December 2019 and July 2020. Sixty-three percent of institutions reported one or more drug shortages per month, with a 34% increase in 2019 from 2018. Treatment delays, reduced doses, or alternative regimens were reported by 75% of respondents. The most difficult agents to obtain were vincristine, vinblastine, intravenous immunoglobulin, leucovorin, and Bacillus Calmette-Guerin. CONCLUSION A survey of US oncology pharmacists indicated that oncology drug shortages occurred frequently in 2020. Shortages led to delays in chemotherapy and changes in treatment or omission, complicated clinical research, and increased risk of medication errors and adverse outcomes.

PURPOSE This study aimed to explore barriers related to the healthcare system (HCS) in implementing quality intravenous (IV) chemotherapy (CT) from the perspectives of cancer patients, family caregivers, and healthcare professionals (HCPs). METHODS Using an explanatory descriptive qualitative method, this study was conducted in 2019. Forty-one participants (6 patients, 5 family caregivers, 12 oncologists, and 18 nurses) were selected through purposive sampling. In-depth semi-structured interviews and field notes were conducted to collect the data, which were analyzed using qualitative content analysis. Lincoln and Guba's criteria of rigor were employed to ensure the trustworthiness of the study. RESULTS Data analysis showed two categories, each with three subcategories: barriers related to healthcare professionals (HCPs) comprised of "educational and communication barriers," "failure to establish trust," and "unskilled healthcare professionals"; barriers related to the health care system management (HCSM), which consists of "inadequate physical and care infrastructures to provide services," "lack of support in the disease trajectory from diagnosis to rehabilitation," and "mismanagement of CT wards/procedures." CONCLUSION The identification and removal of the barriers related to HCPs and HCSM in routine care are crucial. Education of and communication with cancer patients and their family caregivers are two important pillars in the quality of intravenous chemotherapy (IV CT) and this education and communication should be based on individualized care and tailored to the unique needs of each patient.
