Dose 4 You: Dose Division Calculator-A Tool to Reduce Calculation Errors.

Background: Medication dosing calculation errors can cause significant harm to patients, especially in the pediatric population. Crushing tablets for dose division purposes may increase the risk of calculation errors, which can lead to incorrect dosing and compromised patient safety. This study aimed to develop a calculator to eliminate calculation errors associated with dose division. Methods: Using the Wix platform, a group of pharmacists created a user-friendly webpage "Dose 4 You." To enable accurate dose division calculations, the advanced language model Chat GPT and Visual Studio were used. The tool assists healthcare professionals through a step-by-step process, allowing them to enter the necessary dose and medication requirements. The Dose 4 You web page's reliability and feasibility were assessed using retrospective data and validated questionnaires, including the System Usability Scale (SUS), respectively and a Likert scale-based acceptance questionnaire. Results: The Dose 4 You website calculated the required amount of powdered tablet to achieve the desired dose with 100% accuracy. The obtained SUS score was 88.38, indicating excellent usability. The average score of all questions for acceptance was found to be 4.7 ± 0.15 indicating a strong agreement on the tool's usefulness and effectiveness. Conclusion: Dose 4 You is a reliable tool that improves patient safety by streamlining dose calculations and lowering calculation errors. The tool's ease of use, practicality in daily clinical practice, and potential to reduce medication errors are highlighted by the positive perception among healthcare professionals. Dose 4 You's successful implementation demonstrates the power of technology and collaboration in transforming medication administration and improving patient outcomes. Similar innovative solutions to optimize healthcare practices can be explored in future health informatics endeavors.

Idiopathic Hypertension with Multiple Cranial Nerve Palsies: A Case Report and Literature Review.

We report a rare case of idiopathic intracranial hypertension (IIH) with multiple cranial nerve palsies involving cranial nerves VI, VII, IX, and X in a 32-year-old female who had no prior comorbidities. Her condition improved rapidly on a ten-day regimen of acetazolamide and tablet topiramate. IIH should be considered in every patient presenting with persistent headache and multiple cranial nerve abnormalities. This paper also includes a literature review of similar cases.

Development of the EldenCare application: Empowering physicians and clinical pharmacists towards enhancing elderly care.

The growing healthcare burden on the elderly population, combined with an increase in prescription drug use, necessitates the development of novel solutions for improving elderly care. EldenCare connects doctors, clinical pharmacists, and elderly patients. EldenCare was developed by a multidisciplinary team comprising geriatricians, clinical pharmacists, and software engineers. The software offers various features tailored to the needs of each user group, revolutionizing medication management and patient care. For geriatricians, EldenCare provides efficient means of recording patient information, scheduling appointments, and documenting follow-up. Clinical pharmacists can take advantage of the software's advanced features, including identifying medication risks, facilitating dose adjustments, identifying potentially inappropriate medications, and tracking adverse drug reactions. Elderly patients benefit from features such as medication alerts, appointment management, medication lists and an adverse drug reaction diary. The study is divided into five distinct phases: requirements phase, design phase, coding & unit testing phase-frontend, coding & unit testing phase-database/cloud, testing phase. The expected benefits of the EldenCare software include increased medication safety, improved communication between healthcare providers and patients, and improved healthcare outcomes for older adults. EldenCare aims to revolutionise medication management and promote a patient-centered healthcare system by empowering clinical pharmacists and engaging older adults in their care-using technology.

Assessment of Medication Safety Incidents Associated with High-alert Medication Use in Intensive Care Setting: A Clinical Pharmacist Approach.

Background: High-alert medications (HAMs) potentiate heightened risk of causing patient harm ranging from 0.24 to 89.6 errors per 100 prescriptions. High-alert medications are crucially utilized in the intensive care settings (ICUs) due to their excellent potential in delivering therapeutic efficacy, yet these medications could cause severe harm if used inappropriately. Despite the cautious use of these medications, medication safety issues persist, which compromises patient safety. Methods: A prospective interventional study was conducted in ICUs for a period of 6 months. The HAMs were adopted from the Institute for Safe Medication Practices (ISMP) list of HAMs that were used. A suitably designed medication error assessment form was used to capture the necessary data, including demographics, medications, medication error, and the contributing factors. The National Coordinating Council for Medication Error Reporting and Prevention (NCCMERP) index was used to categorize the medication errors (MEs). The error rate was calculated using error rate formula. Continuous variables were expressed as mean ± standard deviation, whereas categorical variables were presented in frequencies and percentages. Results: A total of 165 patients were enrolled during the study period, with 98 (59.4%) being male and 67 (40.6%) female. The majority [54 (32.73%)] of the study participants belonged to the 61-70 age range. A total of 204 MEs were reported, of which [92 (41.5%)] errors were prescribing errors, followed by documentation errors [69 (33.82%)] and administration errors [43 (21.08%)]. The baseline medication error rate was noted to be 160.12/1,000 patient days. Potassium chloride, tramadol, propranolol, aspirin, insulin, and metoprolol were identified as the most common HAMs to cause errors. According to NCC MERP classification, 41.18% were categorized as category B, followed by category C (35.78%). An overall of 666 contributing factors (CFs) were identified for 204 errors. Stress (24.32%) was the most common factor that contributed to the MEs, followed by workload (21.47%). Conclusion: While great strides have been adopted in error prevention, yet the goal of making HAM errors "never" event has not been achieved. Thus, an active surveillance by a clinical pharmacist could support the healthcare team in promoting patient care.

Artificial intelligence in the field of pharmacy practice: A literature review.

Artificial intelligence (AI) is a transformative technology used in various industrial sectors including healthcare. In pharmacy practice, AI has the potential to significantly improve medication management and patient care. This review explores various AI applications in the field of pharmacy practice. The incorporation of AI technologies provides pharmacists with tools and systems that help them make accurate and evidence-based clinical decisions. By using AI algorithms and Machine Learning, pharmacists can analyze a large volume of patient data, including medical records, laboratory results, and medication profiles, aiding them in identifying potential drug-drug interactions, assessing the safety and efficacy of medicines, and making informed recommendations tailored to individual patient requirements. Various AI models have been developed to predict and detect adverse drug events, assist clinical decision support systems with medication-related decisions, automate dispensing processes in community pharmacies, optimize medication dosages, detect drug-drug interactions, improve adherence through smart technologies, detect and prevent medication errors, provide medication therapy management services, and support telemedicine initiatives. By incorporating AI into clinical practice, health care professionals can augment their decision-making processes and provide patients with personalized care. AI allows for greater collaboration between different healthcare services provided to a single patient. For patients, AI may be a useful tool for providing guidance on how and when to take a medication, aiding in patient education, and promoting medication adherence and AI may be used to know how and where to obtain the most cost-effective healthcare and how best to communicate with healthcare professionals, optimize the health monitoring using wearables devices, provide everyday lifestyle and health guidance, and integrate diet and exercise.

Materiovigilance in Intensive Care Units: An Active Surveillance.

Background: Medical devices are the vital part of healthcare system. The use of medical devices is higher in the intensive care units leading to increased exposure rendering the exponential rise in incidence of medical device associated adverse events (MDAEs). Timely detection and reporting of MDAEs can help reduce the disease and associated liabilities. Objective: To determine the rate, patterns, and predictors of MDAEs. Methods: An active surveillance was carried out in the intensive care units (ICUs) of a tertiary care teaching hospital located in southern India. The patients were monitored for MDAEs which were reported based on MvPI guidance document 1.2. The predictors were calculated using an odds ratio at 95% confidence interval. Results: A total of 185 MDAEs were reported amongst 116 patients, of which the majority [74 (63.7%)] were males. Most of the MDAEs were attributed to urethral-catheters [42 (22.7%)] among which a high majority of 34 were associated with urinary tract infections (UTI), followed by ventilators [35 (18.9%)] with all events causing pneumonia. Urethral catheters and ventilators are both classified as categories B and C respectively based on device risk classification provided by the Indian Pharmacopoeia Commission (IPC). Over 58% of MDAEs were reported among the elderly. The causality assessment was possible for 90 (48.6%) MDAEs whereas 86 (46.4%) were probable. The majority of the MDAEs reported were serious [165 (89.2%)] and only [20 (10.8%)] were found to be non-serious on the severity scale. Most [104 (56.2%)] of the devices attributed to MDAEs were single-use devices, of which [103 (55.6%)] were destroyed and only [81 (43.7%)] were retained in healthcare facilities. Conclusions: Despite the best possible care in the intensive care units (ICUs), MDAEs are inevitable, adding to the burden of patients in terms of suffering, disease, extended hospital stay, and increased costs. MDAEs require rigorous monitoring of patients, especially in the elderly population and patients with increased exposure to multiple devices.

Dextromethorphan Induced Dystonia: A Rare Case Report.

Dextromethorphan is a distant derivative of morphine, used as an antitussive agent indicated in standard care for various infections and respiratory conditions ranging from the common cold (rhinoviruses) to severe acute respiratory illness (SARI). Being a derivative of morphine, a natural central nervous system (CNS) depressant, dextromethorphan produces little to no action on CNS when ingested in the prescription dosage. We present a case of a 64-year-old female patient, a known case of ischemic heart disease post angioplasty and stenting to the left anterior descending artery (LAD), with heart failure with reduced ejection fraction (HFrEF), diabetes, hypertension, chronic kidney disease, and hypothyroidism who developed extrapyramidal symptoms post dextromethorphan administration. The incidence of dextromethorphan-induced dystonia is unknown, and the literature review suggests 4 case reports indicating dextromethorphan-induced dystonia, and each of those reports is a case of either accidental overdose or overdose in substance abuse disorder. No cases of these CNS side effects are described among adults with a therapeutic dose of dextromethorphan. This case report serves to sensitize the clinician about this rare occurrence.

Dual mTORC1/2 Inhibition Synergistically Enhances AML Cell Death in Combination with the BCL2 Antagonist Venetoclax.

PURPOSE: Acute myelogenous leukemia (AML) is an aggressive disease with a poor outcome. We investigated mechanisms by which the anti-AML activity of ABT-199 (venetoclax) could be potentiated by dual mTORC1/TORC2 inhibition. EXPERIMENTAL DESIGN: Venetoclax/INK128 synergism was assessed in various AML cell lines and primary patient AML samples in vitro. AML cells overexpressing MCL-1, constitutively active AKT, BAK, and/or BAX knockout, and acquired venetoclax resistance were investigated to define mechanisms underlying interactions. The antileukemic efficacy of this regimen was also examined in xenograft and patient-derived xenograft (PDX) models. RESULTS: Combination treatment with venetoclax and INK128 (but not the mTORC1 inhibitor rapamycin) dramatically enhanced cell death in AML cell lines. Synergism was associated with p-AKT and p-4EBP1 downregulation and dependent upon MCL-1 downregulation and BAK/BAX upregulation as MCL-1 overexpression and BAX/BAK knockout abrogated cell death. Constitutive AKT activation opposed synergism between venetoclax and PI3K or AKT inhibitors, but not INK128. Combination treatment also synergistically induced cell death in venetoclax-resistant AML cells. Similar events occurred in primary patient-derived leukemia samples but not normal CD34+ cells. Finally, venetoclax and INK128 co-treatment displayed increased antileukemia effects in in vivo xenograft and PDX models. CONCLUSIONS: The venetoclax/INK128 regimen exerts significant antileukemic activity in various preclinical models through mechanisms involving MCL-1 downregulation and BAK/BAX activation, and offers potential advantages over PI3K or AKT inhibitors in cells with constitutive AKT activation. This regimen is active against primary and venetoclax-resistant AML cells, and in in vivo AML models. Further investigation of this strategy appears warranted.

Amiodarone-Induced Hyponatremia in An Elderly Patient: A Rare Case Report.

Amiodarone is an antiarrhythmic drug belonging to Vaughan-Williams Class III with additional Class IV effects, which is known to cause many adverse drug reactions (ADRs) necessitating close monitoring. In about 20% of patients, their therapy is discontinued due to adverse effects such as hepatic impairment, thyroid dysfunction, and several pulmonary complications. Although dyselectrolytemia is a common adverse reaction reported with many cardiac medications, the incidence of hyponatremia associated with amiodarone intake is not reported widely in the literature. We are reporting a case of a 73-year-old female patient, with hypertension and ischemic heart disease (IHD) receiving oral amiodarone, presenting with severe hyponatremia, requiring recurrent hospitalization. Amiodarone was found to be responsible after evaluating for the possible causes of hyponatremia. As the incidence of amiodarone-associated hyponatremia is unknown, and not many cases are reported, this case report serves to sensitize the clinician to consider amiodarone-induced hyponatremia as one of the differential diagnoses in cases of unexplained hyponatremia.

Chk1 Inhibition Potently Blocks STAT3 Tyrosine705 Phosphorylation, DNA-Binding Activity, and Activation of Downstream Targets in Human Multiple Myeloma Cells.

The relationship between the checkpoint kinase Chk1 and the STAT3 pathway was examined in multiple myeloma cells. Gene expression profiling of U266 cells exposed to low (nmol/L) Chk1 inhibitor [PF-477736 (PF)] concentrations revealed STAT3 pathway-related gene downregulation (e.g., BCL-XL, MCL-1, c-Myc), findings confirmed by RT-PCR. This was associated with marked inhibition of STAT3 Tyr705 (but not Ser727) phosphorylation, dimerization, nuclear localization, DNA binding, STAT3 promoter activity by chromatin immunoprecipitation assay, and downregulation of STAT-3-dependent proteins. Similar findings were obtained in other multiple myeloma cells and with alternative Chk1 inhibitors (e.g., prexasertib, CEP3891). While PF did not reduce GP130 expression or modify SOCS or PRL-3 phosphorylation, the phosphatase inhibitor pervanadate antagonized PF-mediated Tyr705 dephosphorylation. Significantly, PF attenuated Chk1-mediated STAT3 phosphorylation in in vitro assays. Surface plasmon resonance analysis suggested Chk1/STAT3 interactions and PF reduced Chk1/STAT3 co-immunoprecipitation. Chk1 CRISPR knockout or short hairpin RNA knockdown cells also displayed STAT3 inactivation and STAT3-dependent protein downregulation. Constitutively active STAT3 diminished PF-mediated STAT3 inactivation and downregulate STAT3-dependent proteins while significantly reducing PF-induced DNA damage (γH2A.X formation) and apoptosis. Exposure of cells with low basal phospho-STAT3 expression to IL6 or human stromal cell conditioned medium activated STAT3, an event attenuated by Chk1 inhibitors. PF also inactivated STAT3 in primary human CD138+ multiple myeloma cells and tumors extracted from an NSG multiple myeloma xenograft model while inhibiting tumor growth. IMPLICATIONS: These findings identify a heretofore unrecognized link between the Chk1 and STAT3 pathways and suggest that Chk1 pathway inhibitors warrant attention as novel and potent candidate STAT3 antagonists in myeloma.

Pharmacist-Initiated Medication Error-Reporting and Monitoring Programme in a Developing Country Scenario.

Medication errors (MEs) often prelude guilt and fear in health care professionals (HCPs), thereby resulting in under-reporting and further compromising patient safety. To improve patient safety, we conducted a study on the implementation of a voluntary medication error-reporting and monitoring programme. The ME reporting system was established using the principles based on prospective, voluntary, open, anonymous, and stand-alone surveillance in a tertiary care teaching hospital located in South India. A prospective observational study was carried out for three years and a voluntary Medication Error-reporting Form was developed to report medication errors MEs that had occurred in patients of either sex were included in the study, and the reporters were given the choice to remain anonymous. The analysis was carried out and discussed with HCPs to minimise the recurrence. A total of 1310 medication errors were reported among 20,256 hospitalised patients and the incidence was 6.4%. Common aetiologies were administration errors [501 (38.2%)], followed by prescribing and transcribing errors [363 (28%)]. Root-cause of these MEs were distractions, workload, and communications. Analgesics/antipyretics (19.4%) and antibiotics (15.7%) were the most commonly implicated classes of medications. A clinical pharmacist initiated non-punitive anonymous ME reporting system could improve patient safety.

Persistent 3'-phosphate termini and increased cytotoxicity of radiomimetic DNA double-strand breaks in cells lacking polynucleotide kinase/phosphatase despite presence of an alternative 3'-phosphatase.

Polynucleotide kinase/phosphatase (PNKP) has been implicated in non-homologous end joining (NHEJ) of DNA double-strand breaks (DSBs). To assess the consequences of PNKP deficiency for NHEJ of 3'-phosphate-ended DSBs, PNKP-deficient derivatives of HCT116 and of HeLa cells were generated using CRISPR/CAS9. For both cell lines, PNKP deficiency conferred sensitivity to ionizing radiation as well as to neocarzinostatin (NCS), which specifically induces DSBs bearing protruding 3'-phosphate termini. Moreover, NCS-induced DSBs, detected as 53BP1 foci, were more persistent in PNKP -/- HCT116 cells compared to their wild-type (WT) counterparts. Surprisingly, PNKP-deficient whole-cell and nuclear extracts were biochemically competent in removing both protruding and recessed 3'-phosphates from synthetic DSB substrates, albeit much less efficiently than WT extracts, suggesting an alternative 3'-phosphatase. Measurements by ligation-mediated PCR showed that PNKP-deficient HeLa cells contained significantly more 3'-phosphate-terminated and fewer 3'-hydroxyl-terminated DSBs than parental cells 5-15 min after NCS treatment, but this difference disappeared by 1 h. These results suggest that, despite presence of an alternative 3'-phosphatase, loss of PNKP significantly sensitizes cells to 3'-phosphate-terminated DSBs, due to a 3'-dephosphorylation defect.

Towards patient safety: assessment of medication errors in the intensive care unit in a developing country's tertiary care teaching hospital.

OBJECTIVES: To determine the incidence, causes, patterns and outcomes of medication errors (MEs) in the intensive care unit. METHODS: The ME reporting system was established using the principles based on prospective, voluntary, open, anonymous and stand-alone surveillance in a tertiary care teaching hospital located in southern India. MEs involving patients of either sex were included in the study, and the reporters were given the choice to remain anonymous. The analysis was carried out to determine the patterns, causes and outcomes of the reported errors and was discussed with healthcare professionals (HCPs) to minimise the recurrence of MEs. RESULTS: A total of 292 MEs were reported voluntarily among 5137 admitted patients and the incidence of MEs was 5.6%. Administration errors (n=143, 49%) were the most common type of MEs reported followed by prescription errors (n=56, 19%) and dispensing errors (n=43, 15%). Factors responsible for MEs were related to performance deficit of HCPs due to excessive workload, fatigue, unclear interpersonnel communications and patient-related factors, which accounted for 37.6%, 13.1%, 9.6% and 7.7%, respectively. The majority of the reported MEs had an outcome of category C and A, based on the National Coordinating Council for ME Reporting and Prevention (NCC MERP) outcome category scale, amounting to 42.2% and 41.7%, respectively. CONCLUSIONS: Although the majority of MEs that reached the patients did not cause any harm, providing continuous education and awareness of MEs to HCPs and patients may minimise the scope of the factors that may contribute to MEs and improve overall patient safety.

Nonhomologous end joining of complex DNA double-strand breaks with proximal thymine glycol and interplay with base excision repair.

DNA double-strand breaks induced by ionizing radiation are often accompanied by ancillary oxidative base damage that may prevent or delay their repair. In order to better define the features that make some DSBs repair-resistant, XLF-dependent nonhomologous end joining of blunt-ended DSB substrates having the oxidatively modified nonplanar base thymine glycol at the first (Tg1), second (Tg2), third (Tg3) or fifth (Tg5) positions from one 3' terminus, was examined in human whole-cell extracts. Tg at the third position had little effect on end-joining even when present on both ends of the break. However, Tg as the terminal or penultimate base was a major barrier to end joining (>10-fold reduction in ligated products) and an absolute barrier when present at both ends. Dideoxy trapping of base excision repair intermediates indicated that Tg was excised from Tg1, Tg2 and Tg3 largely if not exclusively after DSB ligation. However, Tg was rapidly excised from the Tg5 substrate, resulting in a reduced level of DSB ligation, as well as slow concomitant resection of the opposite strand. Ligase reactions containing only purified Ku, XRCC4, ligase IV and XLF showed that ligation of Tg3 and Tg5 was efficient and only partially XLF-dependent, whereas ligation of Tg1 and Tg2 was inefficient and only detectable in the presence of XLF. Overall, the results suggest that promoting ligation of DSBs with proximal base damage may be an important function of XLF, but that Tg can still be a major impediment to repair, being relatively resistant to both trimming and ligation. Moreover, it appears that base excision repair of Tg can sometimes interfere with repair of DSBs that would otherwise be readily rejoined.

The NAE inhibitor pevonedistat interacts with the HDAC inhibitor belinostat to target AML cells by disrupting the DDR.

Two classes of novel agents, NEDD8-activating enzyme (NAE) and histone deacetylase (HDAC) inhibitors, have shown single-agent activity in acute myelogenous leukemia (AML)/myelodysplastic syndrome (MDS). Here we examined mechanisms underlying interactions between the NAE inhibitor pevonedistat (MLN4924) and the approved HDAC inhibitor belinostat in AML/MDS cells. MLN4924/belinostat coadministration synergistically induced AML cell apoptosis with or without p53 deficiency or FLT3-internal tandem duplication (ITD), whereas p53 short hairpin RNA (shRNA) knockdown or enforced FLT3-ITD expression significantly sensitized cells to the regimen. MLN4924 blocked belinostat-induced antiapoptotic gene expression through nuclear factor-κB inactivation. Each agent upregulated Bim, and Bim knockdown significantly attenuated apoptosis. Microarrays revealed distinct DNA damage response (DDR) genetic profiles between individual vs combined MLN4924/belinostat exposure. Whereas belinostat abrogated the MLN4924-activated intra-S checkpoint through Chk1 and Wee1 inhibition/downregulation, cotreatment downregulated multiple homologous recombination and nonhomologous end-joining repair proteins, triggering robust double-stranded breaks, chromatin pulverization, and apoptosis. Consistently, Chk1 or Wee1 shRNA knockdown significantly sensitized AML cells to MLN4924. MLN4924/belinostat displayed activity against primary AML or MDS cells, including those carrying next-generation sequencing-defined poor-prognostic cancer hotspot mutations, and CD34(+)/CD38(-)/CD123(+) populations, but not normal CD34(+) progenitors. Finally, combined treatment markedly reduced tumor burden and significantly prolonged animal survival (P < .0001) in AML xenograft models with negligible toxicity, accompanied by pharmacodynamic effects observed in vitro. Collectively, these findings argue that MLN4924 and belinostat interact synergistically by reciprocally disabling the DDR in AML/MDS cells. This strategy warrants further consideration in AML/MDS, particularly in disease with unfavorable genetic aberrations.
