Psoriasis and psoriatic arthritis following use of dostarlimab for endometrial cancer.

Immune checkpoint inhibitors (ICIs) are associated with immune-related adverse events (irAEs), but psoriasis and psoriatic arthritis (PsA) after use of dostarlimab have not been reported. We present a woman who received dostarlimab for endometrial cancer and subsequently developed rash and polyarthralgia, diagnosed as overlapping palmoplantar pustular and plaque psoriasis with PsA. She was treated with discontinuation of dostarlimab, topical steroids, oral methylprednisolone and methotrexate. This case highlights phenotypic heterogeneity in cutaneous irAEs influenced by malignancy and ICI type and underscores the need for multidisciplinary care in treating irAEs. We review three current professional society guidelines for managing irAEs, highlighting their emphasis on management based on severity grading, early initiation of systemic corticosteroids and steroid-sparing agents and discontinuation of ICI for severe events. Certain recommendations deviate from typical approaches to idiopathic rheumatologic disease. Further research is needed to support the ongoing development of approaches to irAE management.

Clinical efficacy of gamma-oryzanol combined with Femoston for perimenopausal syndrome.

BACKGROUND: Perimenopausal syndrome (PMS) is a chronic disease associated with estrogen deficiency. Because of the unsatisfactory outcomes of current conventional treatments for this condition, its treatment must be continuously explored and optimized. AIM: To assess the clinical effectiveness of γ-oryzanol in combination with Femoston for PMS. METHODS: A total of 119 patients with PMS were selected from June 2023 to December 2023, which included 59 and 60 patients in the control and observation group, respectively. The control and observation groups were treated with Femoston and γ-oryzanol + Femoston, respectively. Comparative analyses were performed in terms of clinical effectiveness, safety (dizziness and headache, nausea and vomiting, and breast tenderness), sex hormones [estradiol (E2), luteinizing hormone (LH), and follicle-stimulating hormone (FSH)], lumbar spine (L1-4) and bilateral femoral bone mineral density (BMD), and sleep quality (sleeping time and frequency of awakenings from sleep). RESULTS: Compared with the control group, the observation group had statistically higher total effective rates of treatment; lower overall incidence of adverse events; higher post-treatment E2 levels and L1-4 and bilateral femoral BMD; and lower LH and FSH levels, sleeping time, and frequency of awakenings from sleep after treatment. CONCLUSION: Therefore, for the treatment of PMS, γ-oryzanol combined with Femoston is significantly better than Femoston alone in terms of clinical effectiveness, exhibiting more pronounced clinical advantages in improving safety, sex hormone levels, BMD, and sleep quality.

Antibiotic-induced severe cutaneous adverse reactions: a single-center retrospective study over ten years.

Objective: Severe cutaneous adverse reactions (SCARs) are rare but life-threatening, with antibiotics being the main cause. This retrospective study from a single center was designed to analyze the culprit drugs, clinical features and treatment outcomes of antibiotic-induced SCARs. Methods: We analyzed cases of antibiotic-induced SCARs in a tertiary hospital in China between January 2013 and January 2024, including Steven-Johnson syndrome (SJS) or Stevens-Johnson syndrome-toxic epidermal necrolysis (SJS-TEN) overlap, toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) and acute generalized exanthematous pustulosis (AGEP). Descriptive analysis of the demographic characteristics, clinical manifestations, treatment and prognosis were carried out. Results: Among 354 cases of SCARs, 63 validated antibiotic-related cases were included. Cephalosporins (31.7%), penicillins (25.4%), and quinolones (19.0%) were the most common triggers for SCARs. Overall, liver (50.8%), lungs (31.7%), and kidneys (23.8%) were the most frequently affected organ in SCARs cases. Eight patients (28.6%) in the SJS/SJS-TEN overlap group and 8 patients (80.0%) in the TEN group received combination therapy of corticosteroids and IVIG. Patients with SCARs caused by penicillins or cephalosporins could receive alternative treatments such as lincomamides, quinolones, and tetracyclines. The mortality rate in the TEN group was the highest at 20.0%, followed by the SJS/SJS-TEN overlap group (7.1%), and no deaths were observed in the DRESS and AGEP groups. Conclusion: The identification of the culprit antibiotics and the application of alternative antibiotic therapies are crucial for the management of antibiotic-induced SCARs. If complicated underlying conditions and complications like advanced age, cancer and pneumonia coexist with SCARs, patients might be more at risk for mortality.

Signal mining of adverse reactions in the antiemetic drug ondansetron during pregnancy: A real-world analysis of the FDA adverse event reporting system (FAERS).

BACKGROUND: The aim of this study is to assess the risks associated with the use of ondansetron in pregnant women in real-world based on the Food and Drug Administration adverse Event Reporting System (FAERS). METHODS: The FAERS data from the 2017Q1 to the 2023Q1, which was used by the ratio-of-reporting (ROR) and Bayesian confidence interval progressive neural network (BCPNN) to assess the safety of ondansetron in pregnancy. RESULTS: A total of 15,727 pregnancy population reports were reported, with a total of 1,064 reports of adverse reactions with ondansetron as the primary suspected drug. Ondansetron was involved in a total of 10 system organ classifications (SOCs) of signal generation, and the top three signal intensities were Congenital, familial, and genetic disorders (ROR = 19.1, ROR025 = 17.03; IC = 1.23, IC025 = 1.16), Ear and labyrinth disorders (ROR = 17.11, ROR025 = 12.46; IC = 1.22, IC025 = 1.03), and Cardiac disorders (ROR = 9.48, ROR025 = 8.38; IC = 1.12, IC025 = 1.03); signals of adverse reactions obtained of 216, of which the main ones were Anhedonia (IC = 1.34, IC025 = 1.08), Injury (IC = 1.34, IC025 = 1.19), Left-to-right cardiac shunt (IC = 1.33, IC025 = 1.05). CONCLUSION: The adverse reactions of Ondansetron involve multiple systems and organs, which should cause clinical vigilance. However, due to the limitations of the data, the causal relationship and risk level of adverse reactions cannot be accurately inferred.

Consumption and adverse reaction reporting of herbal medicines among people living with HIV at University teaching hospitals in Blantyre, Malawi and Ibadan, Nigeria.

Background: Consumption of herbal medicines among people living with HIV is a common practice in Sub-Saharan Africa. The utilization of herbal medicines was at 17.5% and 67.9% in Malawi and Nigeria, respectively. There is inadequate data on use and adverse reactions (ADRs) reporting of herbal medicines among people living with HIV (PLWHIV). This study was designed to investigate use and ADRs reporting of herbal medicines among PLWHIV at the University Teaching Hospitals in Blantyre, Malawi and Ibadan, Nigeria. Methodology: A cross-sectional study was conducted among PLWHIV attending Antiretroviral Therapy (ART) clinic at Queen Elizabeth Central Hospital, Blantyre, Malawi and University College Hospital, Ibadan, Nigeria. A structured questionnaire was administered to 360 and 370 participants in Blantyre and Ibadan respectively, through face-to-face interviews after obtaining their informed consent. Results: The prevalence of herbal medicines use among PLWHIV in Malawi and Nigeria was at 80.6% and 55.7% (p<0.001), respectively. The most frequently used herbal medicines in Malawi were Aloe vera (14.0%), Moringa oleifera (14.0%), Zingiber officinale (13.0%) and Allium sativum (7.0%). Likewise, in Nigeria, the most commonly used herbal medicines were Zingiber officinale (15.0%), Vernonia amygdalina (14.0%), Moringa oleifera (9.0%), and Allium sativum (11.0%). The major reason for herbal medicines' use in Malawi was ready availability (42.1%) and perception that it boosts immunity (44.6%) in Nigeria. The PLWHIV reported experiencing suspected herbal medicine ADRs in Malawi (3.9%) and in Nigeria (8.0%). Conclusion: A higher percentage of people living with HIV are using herbal medicines in Malawi as well as in Nigeria. In both countries, a few participants reported experiencing suspected ADRs related to herbal medicines.

Effect of Face Masking on Transmission of SARS-CoV-2.

The efficacy of face masking for the public is not convincing to prevent the transmission of respiratory tract viruses such as SARS-CoV-2 when the criteria of evidence-based medicine are applied. This finding is mainly explained by the results from randomized-controlled trials (RCTs) when a high prevalence of the infection and a high compliance in mask wearing was assured. Throughout these studies no significant protective effect was observed. Observational studies with surgical masks describe a significant protective effect, but are prone to confounders such as physical distance. Respirators do not provide an additional health benefit compared to surgical or medical masks (RCTs). Community masks can even increase the risk of infection (RCTs). Based on the categories of evidence-based medicine, the efficacy results can best be categorized as conflicting evidence. Many relevant adverse events are described when masks are worn for hours such as dyspnea (12.2-52.8%), headache (3.9-73.4%), pruritus (0.0-60.0%), and skin reactions (0.0-85.0%). Their frequency is often higher with respirators. In future pandemics, masks should only be recommended or mandated for settings in which a clinically relevant health benefit can be expected, defined as the prevention of severe, critical or fatal disease, that clearly outweighs the expectable associated adverse reactions.

The radiologist's role in detecting systemic anticancer therapy-related interstitial lung disease: an educational review.

Systemic anticancer therapies (SACTs) are the leading cause of drug-induced interstitial lung disease (ILD). As more novel SACTs become approved, the incidence of this potentially life-threatening adverse event (AE) may increase. Early detection of SACT-related ILD allows for prompt implementation of drug-specific management recommendations, improving the likelihood of AE resolution and, in some instances, widening the patient's eligibility for future cancer treatment options. ILD requires a diagnosis of exclusion through collaboration with the patient's multidisciplinary team to rule out other possible etiologies of new or worsening respiratory signs and symptoms. At Grade 1, ILD is asymptomatic, and thus the radiologist is key to detecting the AE prior to the disease severity worsening. Planned computed tomography scans should be reviewed for the presence of ILD in addition to being assessed for tumor response to treatment, and when ILD is suspected, a high-resolution computed tomography (HRCT) scan should be requested immediately. An HRCT scan, with < 2-mm slice thickness, is the most appropriate method for detecting ILD. Multiple patterns of ILD exist, which can impact patient prognosis. The four main patterns include acute interstitial pneumonia / acute respiratory distress syndrome, organizing pneumonia, hypersensitivity pneumonitis, and non-specific interstitial pneumonia; their distinct radiological features, along with rarer patterns, are discussed here. Furthermore, HRCT is essential for following the course of ILD and might help to determine the intensity of AE management and the appropriateness of re-challenging with SACT, where indicated by drug-specific prescribing information. ILD events should be monitored closely until complete resolution. CRITICAL RELEVANCE STATEMENT: The incidence of potentially treatment-limiting and life-threatening systemic anticancer therapy-related interstitial lung disease (SACT-related ILD) events is likely increasing as more novel regimens become approved. This review provides best-practice recommendations for the early detection of SACT-related ILD by radiologists. KEY POINTS: Radiologists are crucial in detecting asymptomatic (Grade 1) ILD before severity/prognosis worsens. High-resolution computed tomography is the most appropriate method for detecting ILD. Drug-induced ILD is a diagnosis of exclusion, involving a multidisciplinary team. Familiarity with common HRCT patterns, described here, is key for prompt detection. Physicians should highlight systemic anticancer therapies (SACTs) with a known risk for interstitial lung diseases (ILD) on scan requisitions.

Real-world TRAE association between niraparib and platinum-based chemotherapy.

Background: Pre-clinical studies showed the anti-tumor mechanisms of PARP inhibitors (PARPi) and platinum have some crossover and overlap in the DNA damage repair pathway, patients who respond to platinum-based chemotherapy are also more likely to be sensitive to PARPi. This real-world study mainly aimed to evaluate whether TRAE (treatment-related adverse event) between platinum based chemotherapy (PBC) and niraparib are also associated. Methods: Patients received niraparib as maintenance treatment or salvage therapy for advanced ovarian cancer at the First Affiliated Hospital of Gannan Medical University from January 2020 to August 2023 were included. Survival data of niraparib treatment and adverse events occurred during the last platinum-based chemotherapy cycle before starting niraparib treatment and during niraparib treatment are documented. Fisher's exact test were used for correlation analysis. Results: 1. 40 patients treated with niraparib were included in the analysis, including 31 patients treated with niraparib for 1st-line maintenance therapy, 6 patients for PSR (platinum-sensitive recurrence) maintenance therapy, and 3 patients for salvage therapy. The overall median follow-up time was 15.0 months (ranged from 2.2 months to 32.1 months). 2. Overall grade≥3 TRAE (40% vs 70%, p=0.012) including anemia (20% vs 45%, p=0.041) and neutrophil count decreased (17.5% vs 57.5%, p<0.001) was significantly lower during niraparib treatment compared to during chemotherapy. 3. Any grade TRAE (75% vs 100%, p=0.002) including white blood cell count decreased (47.5% vs 87.5%, p<0.001), red blood cell count decreased (57.5% vs 92.5%, p<0.001), anemia (55% vs 87.5%, p<0.001) and neutrophil count decreased (35% vs 85%, p<0.001) were also significantly lower in niraparib treatment group compared with chemotherapy group. No new safety signals were identified. Conclusion: 1. In this real-world practice, we observed that patients with advanced ovarian cancer who experienced any grade and grade ≥3 TRAE during chemotherapy were well tolerated when treated with niraparib, particularly the incidence of any grade and grade ≥3 anemia, and neutrophil count decreased during niraparib treatment were significantly lower compared with that during chemotherapy. 2. For patients with ovarian cancer who have experienced grade ≥3 hematological adverse reactions during prior platinum-based chemotherapy, greater attention should be paid to the monitoring and management of hematological adverse reactions during subsequent treatment with niraparib.

Antifungal prophylaxis against invasive Candida and Aspergillus infection in adult heart transplant recipients: protocol for a systematic review and meta-analysis.

INTRODUCTION: Invasive fungal infections (IFI) can contribute to increased mortality and morbidity rates after heart transplant in adults. The most common causes are Aspergillus and Candida species. There is uncertainty on how effective antifungal prophylaxis is against Candida spp infections and limited guidance on the prevention of Aspergillus spp infections. This systematic review and meta-analysis will assess the literature to see if antifungal prophylaxis reduces the incidence of IFI after heart transplant in adults. METHODS AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic reviews and Meta Analysis guidelines. A systematic search of the Cochrane Library, Web of Science, Scopus, Embase, MEDLINE, and Proquest databases will be undertaken. Reference lists of retrieved publications and conference abstracts will also be searched. Title, abstract and full-text screening will be undertaken by two reviewers. Discrepancies will be resolved by a third reviewer. Studies with paediatric patients, multi-organ transplants, or patients with a second heart transplant will be excluded, along with those who do not have clear definitions and diagnostic criteria for IFI. Risk of bias will be assessed using the Cochrane Risk of Bias 2 tool and the Risk of Bias in Non-randomised Studies of Interventions tool. A meta-analysis will be carried out, but if studies are not deemed to be sufficiently similar, only a narrative synthesis will be undertaken. ETHICS AND DISSEMINATION: Ethical approval is not required for this systematic review as primary data will not be collected. The results of the review will be disseminated through publication in an academic journal and scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42024516588.

Therapeutic effect of epidural dexamethasone palmitate in a rat model of lumbar spinal stenosis.

BACKGROUND: Dexamethasone palmitate (DEP), a prodrug of dexamethasone (DEX), is a synthetic corticosteroid medication distinguished by the inclusion of a fatty acid component known as palmitate. This study introduces DEP as a novel therapeutic option for spinal epidural injection, aiming to provide safer and longer-lasting pain relief as an alternative to for patients with spinal stenosis. METHODS: 40 rats were randomly divided into four groups: those receiving epidural administration of normal saline (NS), and DEP in the lumbar spinal stenosis (LSS) model, and non-model rats receiving epidural NS administration. Paw withdrawal thresholds to mechanical stimulation and motor function (neurogenic intermittent claudication) were observed for up to 21 days. Hematology and blood chemistry analyses were performed 1 week after drug therapy. Tissue samples were collected for steroid pathology examination to evaluate adhesion degree, perineural area inflammation, and chromatolysis in the dorsal root ganglion (DRG), and adrenal gland. RESULTS: The DEX and DEP groups demonstrated significant recovery from mechanical allodynia and motor dysfunction after 2 weeks of drug therapy (p<0.001). However, by the third week, the effect of DEX started to diminish while the effect of DEP persisted. Furthermore, the DEP group exhibited reduced fibrosis and less chromatolysis than the NS group. No steroid overdose or toxin was observed in any group. CONCLUSION: The epidural administration of DEP demonstrated therapeutic efficacy in reducing allodynia and hyperalgesia resulting from chronic DRG compression, thus offering prolonged pain relief. These findings underscore the potential of DEP as a promising treatment alternative for pain associated with LSS, serving as a viable substitute for .

Efficacy and safety of dose-dense gemcitabine plus cisplatin as neoadjuvant chemotherapy for muscle-invasive bladder cancer.

OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of dose-dense gemcitabine and cisplatin (ddGC) as neoadjuvant chemotherapy for muscle-invasive bladder cancer (MIBC). METHODS: Patients with locally advanced MIBC (cT2aN0M0-cT4N1M0) who received ddGC between December 2017 and December 2023 were included. Regimens of ddGC with pegfilgrastim were administered every 2 weeks for 4 cycles, followed by radical cystectomy. The pathological complete response (CR) (pT0N0) and objective response (OR) (

Clopidogrel-induced thrombotic microangiopathy: a case report.

Thrombotic microangiopathy is a serious condition that can be precipitated by exposure to certain medications. Although rare, it is life threatening and requires a high index of clinical suspicion, appropriate laboratory testing and immediate cessation of the offending agent. We present a case of a 75-year-old man with a history of ischaemic heart disease treated with clopidogrel and aspirin. One month after initiating the treatment he developed microangiopathic haemolytic anaemia and thrombocytopenia. Extensive clinical and laboratory investigations suggested thrombotic microangiopathy secondary to clopidogrel. The drug was immediately discontinued and treatment with intravenous corticosteroids was started. Within a week the patient's laboratory parameters normalised, indicating successful recovery. This case highlights the role of early detection and immediate discontinuation of suspected medication in the effective management of clopidogrel-induced thrombotic microangiopathy. Healthcare professionals should consider drug-induced thrombotic microangiopathy as a possible diagnosis in patients receiving clopidogrel who present with thrombocytopenia and microangiopathic haemolytic anaemia.

Cost-effectiveness of preoperative pharmaceutical care consultations: a 5-year analysis.

OBJECTIVES: Preoperative medication errors can be prevented by screening patients through a preoperative pharmaceutical care consultation. The aim of this study was to analyse the cost-effectiveness of implementing such a consultation and to determine which patients would benefit most. METHODS: A retrospective study was conducted that included all patients who underwent a preoperative pharmacy consultation between 2016 and 2020. During this consultation, two part-time pharmacists reviewed patients' appropriate preoperative chronic medication management. All prevented errors were collected and classified by therapeutic group and type of error. A team of pharmacists and anaesthetists assigned to each prevented medication error a probability of causing an adverse event 'p', following the methodology of Nesbit et al by establishing five different 'p' values: 0, 0.01, 0.1, 0.4, and 0.6. 'p' = 1 was not considered. The cost of an adverse event was determined to be between €4124 and €6946 according to current literature, and a sensitivity analysis was performed by increasing the interval by 20% above and below. The cost of employing two part-time specialist pharmacists was estimated to be €59 142. Savings per medication error prevented were calculated as (€4124 OR €6946) × 'p'. Total savings were the sum of all costs associated with prevented medication errors. Patients on chronic medications who were in therapeutic groups with a 0.6 probability of an adverse event or who were in therapeutic groups responsible for 50% of the prevented adverse events were considered prioritisable. RESULTS: 3105 patients attended the consultation and 1179 medication errors were prevented, corresponding to 300 adverse events. 42.2% of the errors had a 'p' of 0.4. The costs avoided by this consultation ranged from €1 237 200 to €2 083 800, while the cost of its implementation was €295 710. The cost-effectiveness ratio was between €4.2 and €7.0 saved per euro invested. In the sensitivity analysis, the ratios ranged from €3.3 to €8.5 per euro invested. Fifteen different therapeutic groups accounted for 90% of the medication errors prevented. The therapeutic groups 'Agents acting on the renin-angiotensin system', 'Antidiabetics, non-insulin (excluding SGLT2)' and 'Antithrombotics: low molecular weight heparins' were responsible for 56% of the prevented adverse events. The therapeutic groups 'Antidiabetics: rapid-acting insulin' and 'Antithrombotic agents: vitamin K antagonists, low-molecular-weight heparins, or direct oral anticoagulants' had a 'p' of 0.6. Therefore, patients in six therapeutic groups should be prioritised for preoperative pharmacy counselling. CONCLUSIONS: The implementation of preoperative pharmaceutical care consultations in Spain has proven to be cost-effective. Incorporating the probability of a medication error causing an adverse event allowed the prioritisation of patients for these consultations. Patients taking anticoagulants, oral antidiabetics, rapid-acting insulins, and agents acting on the renin-angiotensin system benefited the most. This study could serve as a basis for implementing such consultations in other hospitals, as they are effective in reducing the cost of medication errors in surgical patients.

Characterizing immune checkpoint inhibitor-related cutaneous adverse reactions: A comprehensive analysis of FDA adverse event reporting system (FAERS) database.

Background: The increasing adoption of immune checkpoint inhibitors (ICIs) in clinical settings highlights their efficacy in treating diverse conditions, while also emphasizing the potential for common cutaneous adverse reactions to arise. The aim of this study is to investigate a multitude of impacting factors and determinants among patients presenting with ICI-associated cutaneous adverse reactions. Methods: We conducted a comprehensive analysis of ICI-associated cutaneous adverse reactions using data from the FAERS. Our study spans from January 1, 2015, to March 31, 2023, focusing on ICIs, including anti-PD-1, anti-PD-L1, and anti-CTLA-4 agents. Findings: Among the 334,293 reported irAR, 17,431 were identified as cutaneous adverse reactions (ARs). Predominant cutaneous ARs included rash (21.01 %), pruritus (11.22 %), and pemphigoid (3.90 %). Stevens-Johnson syndrome emerged as the most reported severe cutaneous adverse reaction (SCAR) (2.08 %). Anti-CTLA-4 agents exhibited higher cutaneous toxicity compared to anti-PD-1 and anti-PD-L1 agents. Anti-PD-1 agents demonstrated an elevated mortality rate. The combined use of ICIs with chemotherapy amplified the risk of SCAR and mortality. Targeted therapy was a risk factor for cutaneous ARs but was associated with reduced mortality. The median onset day for cutaneous toxicity was 21 days, while for SCAR, it was 23 days. Weight and age were identified as predictors of SCAR, cutaneous toxicity, and mortality. Skin cancer increased skin toxicity, while lung cancer heightened SCAR formation. The number of administered ICIs positively correlated with SCAR, skin toxicity, and mortality. Interpretation: This study highlights the significance of early identification and effective management of cutaneous toxicities, along with personalized follow-up care, as essential strategies for minimizing risks and preventing treatment disruptions.

Clinical and pharmacogenetic features of patients with upper gastrointestinal lesions at a multidisciplinary hospital: the role of nonsteroidal anti-inflammatory drugs.

OBJECTIVES: Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most commonly prescribed medications, but their use can be associated with a number of adverse reactions, including upper gastrointestinal lesions. The aim of the study was to identify clinical and pharmacogenetic factors associated with upper gastrointestinal lesions, including those linked to NSAIDs, in patients at a multidisciplinary hospital. METHODS: The study included 92 patients (mean age 59.4±16.5 years; 47 women), who underwent esophagogastroduodenoscopy during inpatient treatment. Patients' intake of NSAIDs and gastroprotectors during the year before hospitalization was considered. Demographic, clinical, laboratory data of patients were compared between groups, including genotyping for CYP2C9*2 rs179985, CYP2C9*3 rs1057910, CYP2C8*3 rs11572080, CYP2C8*3 rs10509681, PTGS-1 rs10306135, PTGS-1 rs12353214, and PTGS-2 rs20417 using real-time PCR. RESULTS: In NSAIDs+ patients, PTGS1 rs10306135 AT+TT genotypes increased the chance of developing gastrointestinal complications by 5.4 times (95 % CI=1.30-22.27). In total sample, smoking (OR=3.12, 95 % CI=1.15-8.46), and alcohol intake (OR=4.09, 95 % CI=1.05-15.87) increased odds of gastrointestinal damage. In NSAIDs+ patients omeprazole, famotidine and both famotidine and omeprazole during the last year were as ineffective as not taking gastroprotectors; in total sample famotidine (OR=0.19, 95 % CI=0.04-0.93) and two gastroprotectors (OR=0.13, 95 % CI=0.02-0.75) reduced the chance of upper gastrointestinal lesions. CONCLUSIONS: Pharmacogenetic features of patients may significantly contribute to the development NSAIDs-induced upper gastrointestinal injuries.

The value of organ and tissue biovigilance: a cross-sectional analysis.

Introduction: Biovigilance (BV) systems aim to improve the quality and safety of tissues and organs for transplantation. This study describes the Catalan BV system and analyzes its utility. Methods: It is a retrospective analysis of notifications on serious adverse events (SAEs) and reactions (SARs) since the implementation of the BV system (2008 for tissues and 2016 for organs) until 2020. Variables are presented to describe the most common critical steps of the pathway and complications associated with the quality and safety of tissues and organs. Results: A total of 154 and 125 notifications were reported to the Tissue and the Organ BV systems, respectively. Most SAEs were related to unexpected donor diseases and implemented actions were assured on those deemed preventable. Regarding SARs, donor-transmitted infections and malignancies (only organs) were the most common, followed by graft failure (tissues) and process-related (organs). The incidence of SAEs and SARs related to tissue was 3.44‰ and 0.22‰, respectively. The corresponding figures for organs were 31.48‰ and 8.8‰, respectively. Discussion: The analysis of the notifications to the Catalan BV systems has provided useful information about existing risks associated with the quality and safety of tissues and organs, and enabled the implementation of actions targeted to diminish risks and mitigate damage.

Steroid-induced psychosis: a spectrum of neuropsychiatric glucocorticoid side effects.

Glucocorticoid-induced neuropsychiatric side effects have been known since their initial usage and frequently manifest in clinical settings. Despite this, they remain unpredictable, variable and complex to manage, impacting patient outcomes and the healthcare system.We report a case of glucocorticoid-induced psychosis after the administration of dexamethasone post-neurosurgical intervention and its evolution with the initiation of chemotherapy. Although initially manic symptoms were prominent, with the beginning of chemotherapy psychotic symptoms dominated the clinical presentation, followed by depressive symptoms. Despite challenges in diagnosis and management, including adverse reactions to antipsychotic treatment, this case provides critical insights into the variable and dynamic nature of neuropsychiatric side effects induced by glucocorticoids.
