BACKGROUND Hyponatremia is a common postoperative electrolyte disturbance in neurosurgical patients and may present with nonspecific neurocognitive symptoms that overlap with intracranial complications. Carbamazepine (CBZ), frequently used for seizure prophylaxis and pain syndromes, is a recognized cause of drug-induced hyponatremia with a syndrome of inappropriate antidiuretic hormone secretion (SIADH)-like profile. CASE SUMMARY A 62-year-old woman underwent elective left supraorbital craniotomy and microsurgical resection of a left anterior skull-base meningioma. Postoperatively, CBZ 400 mg was initiated twice daily for antiseizure prophylaxis. On postoperative day (POD) 2, she developed somnolence and cognitive slowing with serum sodium 131 mmol/L, which progressed to 123 mmol/L (POD 3) and 119 mmol/L (POD 7) despite isotonic saline and increased dietary sodium. Hypertonic saline (3% NaCl) was introduced with partial correction. Evaluation confirmed hypotonic hyponatremia (serum osmolality 254 mOsm/kg) with inappropriately concentrated urine (urine osmolality 560 mOsm/kg) and elevated urine sodium (68 mmol/L) in a clinically euvolemic patient; thyroid and adrenal functions were normal. Given the temporal association and SIADH-like pathophysiology, CBZ-induced hyponatremia was considered the most likely etiology. CBZ was discontinued and replaced with levetiracetam (titrated to 500 mg twice daily), followed by clinical improvement and steady sodium normalization (132 mmol/L at discharge; 136 mmol/L by POD 19), remaining normal at three-month follow-up. We searched PubMed and Google Scholar to for relevant literature review. CONCLUSION This case highlights CBZ as a potentially reversible cause of significant postoperative hyponatremia after meningioma surgery. Early sodium monitoring after CBZ initiation and prompt substitution with alternative antiseizure therapy should be considered when euvolemic hypotonic hyponatremia develops in the postoperative period.

Background/Objectives: Cardiorenal syndrome type 2 (CRS-2) is characterized by progressive renal dysfunction caused by chronic heart failure (HF) and is associated with increased morbidity and mortality. However, the prognostic value of renal biomarkers in patients with CRS-2 hospitalized for decompensated HF remains unclear. Methods: This prospective observational cohort study included 200 consecutive patients hospitalized for decompensated HF in the Intensive Care Unit of the Clinic for Internal Medicine at the University Clinical Centre Tuzla between April and October 2025. CRS-2 was defined as chronic HF with chronic kidney disease persisting for ≥3 months before admission according to KDIGO criteria. Patients were followed for three months. The primary composite outcome was all-cause mortality or initiation of renal replacement therapy. Results: CRS-2 was identified in 130 patients (65.0%) and was associated with higher in-hospital mortality (32.3% vs. 11.4%, p = 0.002) and three-month mortality (44.6% vs. 21.4%, p = 0.002). Within the CRS-2 subgroup, patients who experienced the primary composite outcome had higher admission levels of cystatin C and urinary albumin-to-creatinine ratio (UACR) and lower estimated glomerular filtration rate (eGFR). ROC analysis demonstrated moderate discriminative ability of cystatin C (AUC 0.739) and UACR (AUC 0.733). In Cox regression analysis, cystatin C (HR 1.534, 95% CI 1.263–1.863, p < 0.001) and UACR (HR 1.003, 95% CI 1.001–1.006, p = 0.001) were significantly associated with the primary composite outcome. Conclusions: Renal dysfunction markers, particularly cystatin C and albuminuria, are associated with early adverse outcomes in CRS-2 patients hospitalized for decompensated HF. Routine assessment of these biomarkers may provide additional prognostic information and support risk assessment in this high-risk population.

<p><strong>Aim </strong>To identify predictors of all-cause mortality and 6-month rehospitalisation in patients with hypertensive crisis, focusing on inflammatory indices, metabolic markers measured at admission, and antihypertensive treatment profiles.</p> <p><strong>Methods </strong>This prospective observational study included 210 adult patients with hypertensive crisis. Demographic, clinical, and therapeutic data were collected, including data on comorbidities, antihypertensive drug use, and treatment adherence. Laboratory parameters obtained at admission included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), homocysteine, and uric acid. Patients were followed for 12 months. Multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were conducted to identify independent predictors.</p> <p><strong>Results </strong>Mortality occurred in 10.9% of patients, and 27.1% were rehospitalised within 6 months. Deceased patients exhibited significantly higher levels of PLR (p=0.0329), SII (p=0.0355), homocysteine (p=0.0488), and uric acid (p=0.021). In multivariate analysis, homocysteine (OR=3.55; p&lt;0.001), uric acid (OR=1.03; p=0.007), PLR (OR=1.04; p=0.047), and SII (OR=1.01; p=0.030) remained independently associated with mortality. Chronic kidney disease (OR=2.15, p=0.012) and poor treatment adherence (OR=1.92; p=0.017) were also significant predictors. ROC analysis demonstrated moderate discriminative power, with AUC values of 0.68 for PLR, 0.66 for SII, 0.65 for homocysteine, and 0.63 for uric acid.</p> <p><strong>Conclusion</strong> Elevated inflammatory indices and metabolic markers, particularly homocysteine and uric acid, were independently associated with increased mortality risk. Additionally, chronic kidney disease and suboptimal adherence to antihypertensive therapy significantly contributed to adverse outcomes. These findings underscore the importance of comprehensive risk assessment and personalised management in this high-risk population.</p>

BACKGROUND Inflammation-driven mechanisms play a central role in adverse outcomes after non-ST-elevation myocardial infarction (NSTEMI), yet simple, widely available biomarkers for early risk stratification remain insufficiently defined. Hemogram-derived indices and iron-related inflammatory markers may provide complementary prognostic information. OBJECTIVE To evaluate the prognostic significance of the mean platelet volume-to-monocyte ratio (MMR) and serum ferritin in predicting major adverse cardiovascular events (MACE) in patients with NSTEMI, and to assess the association of angiotensin-converting enzyme (ACE) inhibitor therapy with clinical outcomes. METHODS This prospective cohort study included 170 consecutive NSTEMI patients admitted to the University Clinical Center Tuzla between February 2022 and January 2023. All patients received dual antiplatelet therapy and high-intensity statins. The baseline evaluation included a complete blood count, serum ferritin, and C-reactive protein. MMR was calculated as the ratio of mean platelet volume to absolute monocyte count. Patients were followed for 12 months for the occurrence of MACE, defined as cardiovascular death, non-fatal myocardial infarction, urgent revascularization, stroke, or hospitalization for heart failure. RESULTS During follow-up, 103 patients (60.6%) experienced MACE. Admission MMR (18.1 ± 11.7 vs 13.2 ± 5.5; P = 0.003) and ferritin levels (284 ± 396 vs 152 ± 109 µg/L; P = 0.001) were significantly higher in patients with events. In multivariable analysis, both MMR (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.02-1.11; P = 0.008) and ferritin (OR 1.28 per 100 µg/L, 95% CI 1.10-1.55; P = 0.003) independently predicted MACE, while ACE inhibitor therapy was associated with a lower risk (OR 0.24, 95% CI 0.08-0.70; P = 0.01). The combined model demonstrated good discriminative performance (AUC 0.72; 95% CI 0.64-0.80). CONCLUSION AND RELEVANCE Elevated admission MMR and ferritin were independently associated with a higher 1-year risk of MACE in patients with NSTEMI. ACE inhibitor therapy was associated with improved outcomes, although causality cannot be inferred. These findings suggest that readily available inflammatory biomarkers may complement established clinical parameters for early risk stratification and support continued guideline-directed pharmacotherapy in NSTEMI.

Aim: To identify the clinicopathological factors associated with five year mortality in patients with colorectal cancer (CRC) treated at Cantonal Hospital Zenica, Bosnia and Herzegovina. Methods: A retrospective cohort of 64 consecutively operated CRC patients (2019 2024) was analysed. The base-line variables included age, sex, tumor stage, histology, metastatic burden, local infiltration, and comorbidities. Five year cumulative mortality was the primary outcome. Risk ratios (RR) with 95 % confidence intervals (CI) were calculated by two by two contingency analysis.Results: The cohort comprised 26 women (40.6 %) and 38 men (59.4 %); their median age was 64 years (IQR 58.8–73.0). Eleven patients (17.2 %) died within five years. Mortality was strongly linked to tumor spread and cardiometabolic disease. Any distant metastasis conferred a fifteen fold increase in risk (9/15 vs 2/49; RR 14.7, 95 % CI 3.6–60.8, p < 0.001), and the involvement of two or more metastatic sites remained prognostic (RR 5.6, 95 % CI 1.9–16.9,p = 0.014). Infiltration of more than two adjacent organs quadrupled mortality (RR 4.4, 95 % CI 1.7–11.6, p = 0.032). Hypertension was present in 10 of the 11 deaths, yielding an RR of 12.1 (95 % CI 1.6–88.8, p = 0.002).Type 2 diabetes also increased risk (RR 3.5, 95 % CI 1.3–9.6, p = 0.040). Patients with three or more comorbid conditions had a nearly four times higher mortality (RR 3.9, 95 % CI 1.3–11.7, p = 0.027).Conclusion: The five year death rate in this Bosnian Herzegovinian CRC cohort was driven chiefly by distant metastasis, extensive local invasion, and cardiometabolic comorbidities—especially hypertension and type 2 diabetes. Early detection of metastatic spread and proactive management of vascular risk factors may improve survival in similar settings.

Symptomatic Meckel’s diverticulum (MD) has various clinical presentations and can be easily misdiagnosed. This multicenter study examines the clinical characteristics, management, and outcomes of patients across five academic pediatric surgery centers in Bosnia & Herzegovina and Serbia. We retrospectively included all pediatric patients (< 18 years) who were surgically and histopathologically confirmed to have symptomatic MD between 2011 and 2020. Demographics, clinical and radiological features, surgical treatment approaches, histopathologic findings, and outcomes were collected and analyzed. Among 151 patients (80.1% male), the median age was 6.7 years (IQR 1.5–10.8). Presentations included intestinal obstruction (38.4%), GI bleeding (37.8%), and peritonitis (23.8%); 63.6% had multiple symptoms. A technetium-99 m scan was positive in 80.7% of bleeding cases. Laparotomy was performed in 72.2%, laparoscopy in 23.2%, and conversion in 4.6%. Partial small bowel resection was required in 80.8%, versus diverticulectomy in 19.2% (p < 0.001). Ectopic mucosa was found in 55.6% (gastric 48.3%, pancreatic 2.6%, both 4.6%; p = 0.05), significantly more common in males (p < 0.001). Postoperative complications occurred in 3.2%, with no mortality. Symptomatic MD displays highly variable clinical presentations. It is often underdiagnosed preoperatively, particularly without GI bleeding, emphasizing the need for high clinical suspicion and tailored surgical approaches.

Introduction Small cell lung cancer (SCLC) is a highly aggressive subtype of lung cancer that accounts for approximately 15% of all lung cancers. Despite advancements in treatment, real-world clinical practice in developing countries often reveals less favorable outcomes than those observed in randomized clinical trials. Material and methods A retrospective analysis was conducted on all patients with extensive-stage SCLC (ES-SCLC) diagnosed or treated at a single center in Bosnia and Herzego-vina. Medical and electronic health records were reviewed to collect data on patients diagnosed with ES-SCLC between 2013 and 2023. The analysis included patient demographics, clinical characteristics, treatment outcomes, and adverse events. Results Ninety-four patients with ES-SCLC were included in the study. Of these, 89.4% were prescribed first-line treatment, and 63.8% received first- line chemotherapy based on cisplatin and etoposide. The median progression- free survival in patients treated with first-line ES-SCLC was five months, with a response rate of 57.5%. The median overall survival of patients treated with first-line chemotherapy in our study was seven months. The most common side effect was hematologic toxicity. Conclusions Our results showed that the outcomes of patients with ES-SCLC in real clinical practice are poor. Further studies of real-world treatment outcomes are essential to validate the findings from randomized controlled trials. Ongoing research is needed to explore strategies for improving outcomes and addressing the unmet needs of patients with ES-SCLC.

Glioblastoma (GBM) remains a major clinical challenge due to limited therapeutic success despite standard treatments including surgery, radiotherapy, and temozolomide (TMZ). Recent evidence links hyperglycemia to cancer progression, and altered glucose metabolism has emerged as a key factor in GBM development. Metformin, an antidiabetic drug, has shown promise in improving survival in GBM patients, possibly due to its ability to cross the blood-brain barrier and target metabolic pathways involved in tumor growth. Preclinical studies suggest metformin may enhance TMZ efficacy by acting on glioma stem cells and overcoming resistance mechanisms. Its activation of AMPK and modulation of Wnt signaling further support its therapeutic potential. However, while early studies and clinical trials have explored metformin’s safety and efficacy, its direct impact on GBM survival remains unclear. Ongoing research aims to clarify its mechanisms and identify responsive patient subgroups. Novel strategies, including PPARγ agonists and nanoerythrosome-based drug delivery systems, are also under investigation to improve metformin’s therapeutic profile. Rigorous clinical trials and mechanistic studies are essential to determine the role of metformin as adjunct therapy in GBM treatment.

Background/Objectives: This study aimed to evaluate the diagnostic and prognostic utility of B7-H3 expression in differentiating low-grade gliomas (LGGs) from high-grade gliomas (HGGs) and to examine its association with clinical outcomes. Methods: This retrospective study included 99 patients with histopathologically confirmed gliomas (42 LGGs and 57 HGGs). B7-H3 expression was assessed using immunohistochemistry and scored by immunoreactive score (IRS). Results: B7-H3 expression was significantly higher in HGG compared to LGG (p < 0.001). The total IRS (B7-H3 A × B) demonstrated strong discriminative power (AUC = 0.816). High B7-H3 expression independently predicted disease progression (OR = 4.9, 95% CI: 2.4–10.1; p < 0.001) and was associated with IDH wild-type status and elevated Ki-67 index. Patients with high B7-H3 had significantly shorter overall survival (median 6 months vs. 42 months) and progression-free survival (median 3 months vs. 25 months) (both p < 0.001). Cox regression confirmed high B7-H3 as an independent predictor of mortality (HR = 2.9, 95% CI: 1.7–4.7; p < 0.001) and progression (HR = 2.6, 95% CI: 1.6–4.2; p < 0.001). Conclusions: B7-H3 expression is a reliable biomarker for distinguishing HGG from LGG and is independently associated with worse survival outcomes. Its assessment may aid in glioma classification and prognostication.

A systematic review with meta-analysis (SRMA) represents the pinnacle of evidence, but its validity depends on methodological rigor. This narrative review synthesizes recommendations from major reporting frameworks—Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA-2020), Meta-Analysis of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Overviews of Reviews (PRIOR)—into a concise checklist for peer reviewers. The checklist addresses common sources of bias that often escape editorial assessment. Initially, it outlines how reviewers should assess the rationale for an SRMA by identifying existing syntheses on the same topic and determining whether the new work provides substantive novelty or a significant update. Best practices are summarized for protocol registration, comprehensive search strategies, study selection and data extraction, risk-of-bias evaluation, and context-appropriate statistical modeling, with a specific focus on heterogeneity, small-study effects, and data transparency. Case examples highlight frequent pitfalls, such as unjustified pooling of heterogeneous designs and selective outcome reporting. Guidance is also provided for formulating balanced, actionable review comments that enhance methodological integrity without extending editorial timelines. This checklist equips editors and reviewers with a structured tool for systematic appraisal across clinical disciplines, ultimately improving the reliability, reproducibility, and clinical utility of future SRMAs.

Background and Objectives: Idiopathic normal-pressure hydrocephalus (NPH) is a treatable, but diagnostically challenging condition in the elderly marked by gait disturbance, cognitive decline, and urinary incontinence. Ventriculoperitoneal (VP) shunting is effective, but the prognostic significance of symptom duration before surgery remains unclear. This systematic review evaluates symptom duration in NPH patients with postoperative outcomes. Methods: A systematic search of PubMed, Scopus, and Embase was conducted per PRISMA guidelines. Studies were included if they assessed clinical or radiological outcomes of VP shunting in adult NPH patients, reported symptom duration, and had a follow-up of at least one month. Clinical outcomes (MMSE, TUG, NPH score) were qualitatively analyzed due to study heterogeneity. Results: Twenty-four studies comprising 1169 patients were included (mean age: 72.45 years; mean symptom duration: 33.04 months). Most studies reported clinical improvement after VP shunting. However, few directly evaluated the effect of symptom duration, yielding inconsistent findings: some suggested better outcomes with shorter symptom duration, while others found no clear correlation. Larger studies often lacked conclusive data, and no randomized controlled trials were identified. Conclusions: VP shunting remains an effective intervention for NPH; however, evidence supporting the predictive value of preoperative symptom length is inconclusive. This review highlights the need for standardized diagnostic protocols and larger prospective studies to clarify this association and optimize surgical timing.

Background Non-ST-elevation myocardial infarction (NSTEMI) is frequently associated with systemic inflammation and metabolic dysregulation. Indices derived from routine laboratory tests that reflect systemic inflammatory and lipid-inflammatory status may offer better prognostic insight. This study aimed to evaluate the association between selected indices and short-term major adverse cardiovascular events (MACE) and all-cause mortality in patients with NSTEMI treated with dual antiplatelet therapy (DAPT) and statin. The selected indices reflect key mechanisms involved in NSTEMI pathophysiology, including insulin resistance, atherogenic dyslipidemia, and inflammation. Materials and methods This prospective observational study included 171 patients with NSTEMI admitted to the Intensive Care Unit of the Clinic for Internal Medicine at the University Clinical Centre Tuzla between February 1, 2022, and January 31, 2023. Blood samples were collected upon admission and 24 hours subsequently. The following indices were calculated: triglyceride-glucose index (TyG), triglyceride-to-high-density lipoprotein ratio (TG/HDL), atherogenic index of plasma (AIP), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and pan-immune-inflammation value (PIV). Outcomes were tracked during hospitalization and up to three months post-discharge. MACE was defined as cardiovascular death, reinfarction, stroke, or unplanned revascularization. All patients underwent coronary angiography; revascularization was performed when clinically indicated. Exclusion criteria included active malignancy, infection, or inflammatory disease. Logistic regression was adjusted for age, diabetes, and other clinical variables. Missing data were handled using the pairwise deletion method. Results High levels of TyG at admission were independently associated with MACE (odds ratio (OR) 1.7; 95% confidence interval (CI) 1.0-2.8; p = 0.037). All-cause mortality occurred in 14.6% of patients (n = 25), while MACE occurred in 60 patients. Independent predictors of mortality included elevated TyG at admission (OR 2.2; 95% CI 1.1-4.4; p = 0.034), TG/HDL at 24 hours (OR 1.4; 95% CI 1.1-1.7; p = 0.007), AIP at 24 hours (OR 5.7; 95% CI 1.1-28.9; p = 0.035), and NLR at 24 hours (OR 1.1; 95% CI 1.0-1.2; p = 0.002). PLR and PIV at 24 hours were also significantly associated with mortality. Optimal cut-off values were TyG ≥ 8.9, AIP ≥ 0.35, and NLR ≥ 4.5. NLR had the highest estimated area under the curve (AUC ≈ 0.78). Conclusion In NSTEMI patients treated with DAPT and statin, several inflammatory and lipid-inflammatory indices were independently associated with short-term mortality. Indices measured at 24 hours had a stronger prognostic value than baseline values. Serial monitoring may aid early risk stratification. Outcomes were assessed during hospitalization and via structured follow-up up to three months post-discharge.

BACKGROUND Non-ST segment elevation myocardial infarction (NSTEMI) poses significant challenges in clinical management due to its diverse outcomes. Understanding the prognostic role of hematological parameters and derived ratios in NSTEMI patients could aid in risk stratification and improve patient care. AIM To evaluate the predictive value of hemogram-derived ratios for major adverse cardiovascular events (MACE) in NSTEMI patients, potentially improving clinical outcomes. METHODS A prospective, observational cohort study was conducted in 2021 at the Internal Medicine Clinic of the University Hospital in Tuzla, Bosnia and Herzegovina. The study included 170 patients with NSTEMI, who were divided into a group with MACE and a control group without MACE. Furthermore, the MACE group was subdivided into lethal and non-lethal groups for prognostic analysis. Alongside hematological parameters, an additional 13 hematological-derived ratios (HDRs) were monitored, and their prognostic role was investigated. RESULTS Hematological parameters did not significantly differ between non-ST segment elevation myocardial infarction (NSTEMI) patients with MACE and a control group at T1 and T2. However, significant disparities emerged in HDRs among NSTEMI patients with lethal and non-lethal outcomes post-MACE. Notably, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were elevated in lethal outcomes. Furthermore, C-reactive protein-to-lymphocyte ratio (CRP/Ly) at T1 (> 4.737) demonstrated predictive value [odds ratio (OR): 3.690, P = 0.024]. Both NLR at T1 (> 4.076) and T2 (> 4.667) emerged as significant predictors, with NLR at T2 exhibiting the highest diagnostic performance, as indicated by an area under the curve of 0.811 (95%CI: 0.727-0.859) and OR of 4.915 (95%CI: 1.917-12.602, P = 0.001), emphasizing its important role as a prognostic marker. CONCLUSION This study highlights the significant prognostic value of hemogram-derived indexes in predicting MACE among NSTEMI patients. During follow-up, NLR, PLR, and CRP/Ly offer important insights into the inflammatory processes underlying cardiovascular events.

Background Non-ST-elevation myocardial infarction (NSTEMI) represents a prevalent form of acute coronary syndrome associated with substantial early risk of adverse outcomes. Inflammatory and metabolic disturbances are increasingly recognized as key contributors to the disease. Hematologic indices such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and pan-immune-inflammation value (PIV), along with the triglyceride-glucose index adjusted for BMI (TyG-BMI), have emerged as promising prognostic markers. However, their dynamic behavior in early NSTEMI remains insufficiently explored. Materials and methods This prospective study included 170 patients hospitalized for NSTEMI at the University Clinical Centre Tuzla between February 2022 and January 2023. Hematologic and metabolic indices were calculated at admission and repeated 24 hours later. Patients were followed for three months to document major adverse cardiovascular events (MACE), including cardiovascular death, reinfarction, and urgent revascularization. The median age was 67 years, and 60.6% of patients were male. Hypertension, hyperlipidemia, and diabetes mellitus were the most common comorbidities. Results Significant 24-hour reductions were observed in NLR, PLR, SII, SIRI, and PIV (all p < 0.01), while C-reactive protein (CRP) levels more than doubled (p < 0.001). Patients who developed MACE showed persistently elevated inflammatory indices and smaller declines in PIV and SIRI. Change in SIRI (ΔSIRI) demonstrated the strongest predictive value (AUC = 0.63), followed by SII and TyG-BMI. Notably, reduced resolution of PIV and persistently elevated TyG-BMI were significantly associated with adverse outcomes. Overall, MACE occurred in 51.2% of patients, including a 14.7% mortality rate. Conclusion Early changes in systemic inflammation and metabolic stress, particularly SIRI and TyG-BMI dynamics, offer valuable prognostic insight and may enhance early risk stratification in NSTEMI patients.

Objectives Generative artificial intelligence (GAI) tools can enhance the quality and efficiency of medical research, but their improper use may result in plagiarism, academic fraud and unreliable findings. Transparent reporting of GAI use is essential, yet existing guidelines from journals and institutions are inconsistent, with no standardised principles. Design and setting International online Delphi study. Participants International experts in medicine and artificial intelligence. Main outcome measures The primary outcome measure is the consensus level of the Delphi expert panel on the items of inclusion criteria for GAMER (Rreporting guideline for the use of Generative Artificial intelligence tools in MEdical Research). Results The development process included a scoping review, two Delphi rounds and virtual meetings. 51 experts from 26 countries participated in the process (44 in the Delphi survey). The final checklist comprises nine reporting items: general declaration, GAI tool specifications, prompting techniques, tool’s role in the study, declaration of new GAI model(s) developed, artificial intelligence-assisted sections in the manuscript, content verification, data privacy and impact on conclusions. Conclusion GAMER provides universal and standardised guideline for GAI use in medical research, ensuring transparency, integrity and quality.
