Objective:
To evaluate the in vitro anti-diabetic effects of Bryonia dioica roots extracts, including water-acetone extracts and their ethyl acetate and butanol fractions, and chloroform-methanol extracts.
Methods:
The total phenolic, flavonoid, flavonol, and saponin contents in the Bryonia dioica root extracts (chloroform-methanol extracts, water-acetone extracts and their ethyl acetate and butanol fractions) were determined using colorimetric methods with Folin-Ciocalteu, aluminum trichloride, and vanillin reagents, respectively. The in vitro anti-diabetic activity was evaluated by measuring the half-maximal inhibitory concentration (IC50) values of these root extracts against α-amylase and α-glucosidase activities, evaluating their effects on α-amylase kinetics, quantifying the inhibition of bovine serum albumin (BSA) glycation using fluorometry to assess advanced glycation end products (AGE) production, and determining glucose uptake by isolated rat hemidiaphragm. Additionally, molecular docking analysis was conducted to investigate the binding affinity and interaction types between Bryonia dioica ligands (cucurbitacin B, bryogénin, vitexin, and isovitexin) and target enzymes, and a phytochemical-targets interaction network was constructed.
Results:
For α-amylase inhibition, ethyl acetate fraction demonstrated the most potent activity (IC50 = 145.95 µg/mL), followed by chloroform-methanol extract (IC50 = 300.86 µg/mL). Water-acetone root extracts and their ethyl acetate and butanol fractions inhibited the α-glucosidase activity with IC50 values ranging from 562.88 to 583.90 µg/mL. Both ethyl acetate and butanol fractions strongly inhibited non-enzymatic BSA glycation (IC50 = 318.26 and 323.12 µg/mL, respectively). The incubation of isolated rat hemidiaphragms with the ethyl acetate fraction (5 mg/mL) significantly increased glucose uptake (35.16%; P <

INTRODUCTION:
Postoperative urinary retention (POUR) frequently complicates the course of patients following hip and knee arthroplasty. Intrathecal morphine (ITM) was identified as a significant risk factor for POUR. The objective of this study was to investigate the incidence and risk factors for POUR in fast-track total joint arthroplasty (TJA) under spinal anaesthesia (SA) with ITM.
METHODS:
We conducted a retrospective study of our institutional joint registry of patients who underwent primary TJA under SA with ITM between October 2017 and May 2021. Preoperative (baseline demographics) and perioperative data were collected. The primary outcome was the incidence of POUR after 8 h or earlier, either due to lack of voiding or according to patient's complaints of bladder distension. Univariate and adjusted analyses were performed to identify predictors of POUR.
RESULTS:
Sixty-nine patients who underwent total knee arthroplasty (TKA) and 36 patients who underwent total hip arthroplasty (THA) under SA with ITM were included in the study. POUR requiring bladder catheterisation was diagnosed in 21% of patients. Independent predictors of POUR were age over 65 years and male gender.
CONCLUSIONS
SA with ITM for TJA is associated with high rates of POUR in males older than 65 years of age. Other previously identified risk factors such as intraoperative fluid administration or comorbidities may not be as influential.

INTRODUCTION:
Oral cancer is a major public health concern in India. Both conventional and altered fractionation radiotherapy schedules have been used in curative treatment of oral cancer. This study aimed to retrospectively evaluate the clinical profile and treatment outcomes of patients with carcinoma buccal mucosa who underwent treatment with definitive hypofractionated accelerated radiotherapy.
METHODS:
A total of 517 patients treated from January 2011 to December 2016 were eligible for the analysis. All patients were treated with definitive hypofractionated accelerated radiotherapy schedule of 5,250 cGy in 15 fractions over 3 weeks. Survival estimates were generated using the Kaplan-Meier method.
RESULTS:
At a median follow-up of 77.4 months, 473 (91.5%) patients attained complete remission with radiation therapy. The 5-year disease-free survival (DFS) and overall survival (OS) rates were 69% and 80.5%, respectively. The 5-year OS for stage I, II, III and IVa tumours was 80.3%, 84.4%, 81.4% and 73.7%, respectively, and the DFS was 75.7%, 73.2%, 69.6% and 60.2%, respectively. Age >50 years was found to be a significant factor affecting DFS ( P = 0.026) and OS ( P = 0.048) in multivariate analysis. Fifty-three (10.3%) patients developed osteoradionecrosis of the mandible.
CONCLUSION
Excellent outcome could be achieved in less-aggressive, low-volume carcinoma of the buccal mucosa with radical accelerated hypofractionated radiotherapy. A radiotherapy schedule over a 3-week period is useful in high-volume centres.

INTRODUCTION:
Risk-based screening (RBS) has emerged as a promising alternative to age-based cancer screening. However, evidence regarding real-world implementation outcomes remains fragmented. Thus, a systematic review was conducted to evaluate the implementation metho-dologies and outcomes of RBS programmes across different cancer types.
METHODS:
MEDLINE, Embase, CINAHL, Web of Science, Cochrane Central Register of Controlled Trials and Scopus were systematically searched from their respective dates of inception up to 8 July 2024. Prospective and rando-mised controlled trials (RCTs), which implement the RBS of cancer in an asymptomatic population, or studies retrospectively evaluating the outcomes of the same were included. Geographic distribution, population characteristics, RBS methodology, diagnostic accuracy and clinical outcomes were narratively synthesised.
RESULTS:
Among the 33 included studies (i.e. 21 prospective cohort, 8 RCTs, 3 retrospective and 1 non-RCT), sample sizes ranged from 102 to 1,429,890 participants. Most RBS trials were conducted in China (n=7, 21.2%), followed by the Netherlands (n=4, 12.1%) then the US, Australia and Sweden (n=3, 9.8%). Studies predominantly examined colorectal (27.3%), breast (21.2%) and prostate cancer (18.2%). Three main stratification approaches emerged: algorithmic (48.5%), validated risk models (39.4%) and physician assessment (9.1%). Implementation outcomes showed higher uptake in moderate-risk (75.4%) compared to high-risk (71.3%) and low-risk groups (67.9%). Five studies demonstrated cost-effectiveness with increased quality-adjusted life years, while 12 studies showed superior or non-inferior cancer detection rates compared to traditional screening.
CONCLUSION
The RBS of cancer has the potential to optimise healthcare resource allocation while minimising harm and increasing receptiveness for patients. More work is needed to evaluate long-term outcomes prior to the scaling of RBS programmes.

BACKGROUND:
Transcatheter Aortic Valve Implantation (TAVI) has changed the treatment paradigm of the aortic stenosis (AS). It has become the treatment of choice in patients with symptomatic AS and surgical high risk, and a valid alternative to surgical aortic valve replacement in patients with low and medium surgical risk. Despite numerous evidence on clinical results, indications and benefits, only a few studies analyse it from patient's perspective and the impact of TAVI on them. The objective of this study is to evaluate the experience of patients undergoing TAVI.
METHODS:
Cross-sectional, descriptive observational study in two Spanish hospitals, with a establish Nurse TAVI program, with 100 patients undergoing TAVI. A specific questionnaire was designed (VALVEX questionnaire) and a pilot study was conducted by a multidisciplinary team of doctors, nurses and patients. The questionnaire was given to patients at 30 days after TAVI procedure during the follow up at the TAVI nurse clinic.
RESULTS:
The study demonstrated a mean satisfaction of 9 for the TAVI program, with 96% of patients that would recommend TAVI to other patients. Patients scored a high satisfaction on the information received prior to the procedure. During the procedure and admission, the satisfaction was high in relation to the care received. During the follow up, satisfaction was high in relation to the role of the TAVI nurse, for the information and continuation of care during the procedure, in reducing anxiety, organising their admission and understanding the process. However, questions with less scores were related to hospital catering, delay between diagnosed and treatment, and patient decision-making process.
CONCLUSION
The evaluation of patient experience allows us to improve the information given to the patient during their TAVI process and it can also allow patients to be more relax, aware and prepared for the procedure. Continuous follow up enables monitoring of patient recovery and helps to discuss any doubts improving patient's satisfaction. The use of PREMs and PROMs associated to TAVI pathway combined with an active participation of the patient on the design of the questionnaire is essential for keeping the patient in the centre of the TAVI pathway.

Purpose:
To compare the clinical outcomes of XEN45 gel stent implantation surgery (ab externo, open conjunctiva) with those of trabeculectomy.
Methods:
We retrospectively reviewed electronic medical record of 57 patients (62 eyes) treated with XEN implantation surgery (ab externo, open conjunctival approach) between April 1, 2021, and July 31, 2023, by the same surgeon. Preoperative clinical data including intraocular pressure (IOP), the number of glaucoma medications, and visual acuity were collected from 1 day to 12 months postoperatively. These data were compared and analyzed with those of 67 patients (78 eyes) received trabeculectomy between February 1, 2017, and April 30, 2022, by the same surgeon. Statistical analyses were performed with p < 0.05 as significant.
Results:
Complete surgical success rate was 33.9% and 57.7% of the XEN and trabeculectomy groups, respectively (p = 0.005). The qualified success rate was 79.0% and 93.6%, respectively (p = 0.011). Postoperatively, the XEN group used more glaucoma medications than the trabeculectomy group (1.21 ± 1.05 vs. 0.69 ± 0.90, p = 0.003 at postoperative month 12). After postoperative month 1, the XEN group had a higher IOP (15.77 ± 5.07 mmHg vs. 13.17 ± 3.81 mmHg; at postoperative month 12, p = 0.001) and lower corneal astigmatism than the trabeculectomy group (1.32 ± 0.79 diopters vs. 1.88 ± 1.45 diopters, p = 0.020 at postoperative month 6). There was no significant difference in preoperative and postoperative best-corrected visual acuity (logMAR) between the groups at any of the follow-up period (favorable visual acuity subgroup; logMAR < 0.7). Postoperative complications were 0 cases of XEN group and 13 cases of trabeculectomy group (0% vs. 16.7%, p = 0.001). Also, XEN surgery (24 minutes 40 seconds ± 6 minutes 26 seconds) had a shorter operation time than the trabeculectomy (40 minutes 18 seconds ± 8 minutes 27 seconds, p < 0.001).
Conclusions
Compared to trabeculectomy, XEN surgery (ab externo, open conjunctiva) showed relatively lower effectiveness (surgical success rate, IOP reduction). However, it demonstrated advantages as a minimally invasive glaucoma surgery, including a surgical success rate approaching about 80%, stability in inducing corneal astigmatism, fewer postoperative complications, and shorter operation times.

Purpose:
Curcumin as a potent anti-inflammatory and cancer-prevention molecule was labeled with n.c.a 177Lu. The combi-nation of 177Lu as a theranostic agent and curcumin as an anti-cancer can be considered for nuclear medicine.
Methods:
First, n.c.a 177Lu (specific activity = 48 Ci/mg) was prepared using the extraction chromatography method. Then,semi-empirical quantum chemical calculations were applied to get a deeper insight into the complexation reaction between Lu+3 and curcumin ligand. UV-Vis spectrophotometry was used for the determination of the metal-to-curcumin ratio. Sub-sequently, a mixture of (111–333 MBq) n.c.a 177Lu, 50 µL curcumin solution in ethanol, and 450 µL acetate buffer at pH = 5was incubated for 1 h at 95 ºC. The Lu-curcumin complex chemical structure was characterized using IR spectroscopy.Finally, the prepared complex was analyzed by different quality control tests.
Results:
Complexometry using UV-Vis studies showed a 1:2 ratio for Lutetium: curcumin complex which is in agreement with theoretical calculations. The IR-spectra analysis also confirmed the complex formation. The radiochemical purity of n.c.a 177Lu -curcumin was more than 95% as determined by radio-TLC. The stability of up to 48 h was observed for theprepared complex in serum. The partition coefficient was calculated for the compound (logP = -0.31). Evaluating biodistri-bution in tumoral mice exhibited high tumor uptake (%ID/gtissue = 2.03).
Conclusion
The promising results showed that n.c.a 177Lu-curcumin can be considered as a possible radiopharmaceutical agent for therapeutic applications.

Journal of Neurogastroenterology and Motility 2025;31(1):28-37
Background/Aims:
Amitriptyline is prescribed off-label for irritable bowel syndrome (IBS). We conducted a meta-analysis to assess its efficacy.
Methods:
A systematic literature review was conducted until November 10, 2023, using MEDLINE, Embase, Cochrane Library, and Web of Science to study the efficacy of amitriptyline in patients with IBS. We included all randomized controlled trials that compared amitriptyline to placebo. Revised Cochrane risk-of-bias tool was used to assess the quality of studies. Meta-analyses were performed using a bivariate random-effects model. Statistical analyses were performed using R Software 4.2.3 and heterogeneity was assessed with I 2 statistics.
Results:
Seven trials were included with 796 patients (61% female). Amitriptyline was associated with better treatment response (OR, 5.30; 95% CI, 2.47 to 11.39; P < 0.001), reduced Irritable Bowel Syndrome Symptom Severity Scores (MD, –50.72; 95% CI, –94.23 to –7.20; P = 0.020) and improved diarrhea (OR, 10.55; 95% CI, 2.90 to 38.41; P < 0.001). No significant difference between the 2 groups regarding the adverse effects was observed. Three trials showed an overall low risk of bias, 2 trials showed an overall high risk of bias due to randomization and missing data, and 2 trials had some concerns regarding missing data.
Conclusions
Amitriptyline was found to be well-tolerated and effective in treating IBS compared to placebo. These findings support the use of amitriptyline for the management of IBS, particularly among patients with the IBS diarrhea subtype. Future research should focus on the dose-dependent effects of amitriptyline in IBS to better guide clinicians in personalized titration regimens.
