Objectives: Catastrophic health expenditures (CHE) is a well-established indicator of financial risk protection. This study aimed to examine the contribution of medication expenditure to CHE and the associated socioeconomic inequalities. Methods: Data were drawn from 6 nationally representative income and expenditure surveys covering the period 2019–2024. Using the budget share method, CHE was defined as out-of-pocket (OOP) health payments exceeding 25% of a household’s total consumption expenditure. The contribution of medication expenditures to CHE was then calculated as the difference in the proportion of households experiencing CHE with and without medication payments. Socioeconomic inequalities were quantified using the Concentration Index (CI), and decomposition analysis was conducted to identify the primary drivers of overall socioeconomic inequality in the contribution of medication expenditures to CHE. Results: During the study period, medications represented a substantial share of household health expenditures and contributed to CHE. In 2024, OOP spending on medications accounted for 31.2% of total health expenditures, while the contribution of medication expenditures to CHE was 1.28%. The CI indicated that the contribution of medication expenditures to CHE was concentrated among poorer households. Decomposition analysis further identified medium-sized households, male-headed households, households with employed heads, insured households, and urban households as the main contributors to this socioeconomic inequality. Conclusions In Iran, OOP payments for medications constitute a substantial share of household healthcare expenditures and contribute to CHE. Because the roots of inequality extend beyond the healthcare system, addressing this issue requires a comprehensive, cross-sectoral strategy that integrates broader social and economic policies.

Objective: Ketamine is a promising drug for analgesia in emergency medicine, but the high rate of side effects is a barrier to widespread usage. We hypothesized that ketamine bolus followed by ketamine infusion would provide a more even and longer duration of analgesia and lower rates of side effects in comparison to bolus-only administration. Methods: This was a double-blinded clinical trial. Eligible trauma patients were randomly allocated with the numeric rating scale ≥6 in two study groups. The first group received a dose of 0.3 mg/kg of ketamine over 1 minute, followed by an infusion of saline 0.9% over the next 30 minutes (bolus-only group). The second group was given 0.15 mg/kg of ketamine over 1 minute, followed by an infusion of 0.15 mg/kg over the next 30 minutes (bolus-and-infusion group). The primary outcome was to measure the average reduction in pain scores. Results: In total, 80 patients were recruited. Of these, 77 patients were analyzed. Both groups achieved a statistically significant decrease in pain scores (all P<0.001). After 30 minutes, patients in the bolus-and-infusion group reported lower pain scores in all intervals with lower rates of need for rescue analgesia, but this difference was not statistically significant. Vital signs remained stable during the study in both groups. No statistically significant difference was observed between study groups for any side effect (P<0.05). Conclusion Both administration protocols resulted in significant pain control. No statistically significant difference was observed between study groups in terms of analgesic efficacy and side effects.

AIM:To investigate the effect of wearing corneoscleral contact lens on visual acuity, and corneal parameters in keratoconus patients.METHODS:In this prospective study, 43 cases(83 eyes)with keratoconus were included and examined. A corneoscleral contact lens was fitted, and thorough exams were carried out at baseline, 3 and 6 mo after wearing lenses, including slit lamp examination, objective and subjective refraction, uncorrected visual acuity(UCVA), and best-corrected visual acuity(BCVA), keratometry(Kmax, K1 and K2), central corneal thickness and endothelial cells count.RESULTS: Mean BCVA(LogMAR)improved from 0.34±0.23 with the spectacles to 0.03±0.05 with the corneoscleral contact lenses in 6 mo(P<0.001). Kmax changed from 52.80±5.93 D to 51.51±5.64 D in 6 mo(P<0.001), central corneal thickness changed from 483.84±34.69 μm to 476.28±35.38 μm(P<0.001), and endothelial cell count changed from 2559.18±275.7 cells/mm2 to 2572.73±274.3 cells/mm2 after wearing corneoscleral contact lens for 6 mo(P<0.001).CONCLUSION: Corneoscleral lenses could significantly increase visual acuity, since there were no clinical noticeable changes in the corneal parameters, this lenses can be used safely in patients with keratoconus.

Background: and Purpose Repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere represents a new option in treating essential tremor (ET) patients. We aimed to determine the efficacy of cerebellar rTMS in treating ET using different protocols regarding the number of sessions, exposure duration, and follow-up duration. Methods: A randomized sham-controlled trial was conducted, in which 45 recruit patients were randomly allocated to 2 groups. The first (active group) comprised 23 patients who were exposed to 12 sessions of active rTMS with 900 pulses of 1-Hz rTMS at 90% of the resting motor threshold daily on each side of the cerebellar hemispheres over 4 weeks. The second group (sham group) comprised 22 patients who were exposed to 12 sessions of sham rTMS. Both groups were reassessed at baseline and after 1 day, 1 month, 2 months, and 3 months using the Fahn-Tolosa-Marin tremor-rating scale (FTM). Results: Demographic characteristics did no differ between the two groups. There were significant reductions both in FTM subscores A and B and in the FTM total score in the active-rTMS group during the period of assessment and after 3 months (p=0.031 and 0.011, respectively).However, subscore C did not change significantly from baseline when assessed at 2 and 3 months (p=0.073 and 0.236, respectively). Furthermore, the global assessment score was significantly higher in the active-rTMS group (p>0.001). Conclusions Low-frequency rTMS over the cerebellar cortex for 1 month showed relative safety and long-lasting efficacy in patients with ET. Further large-sample clinical trials are needed that include different sites of stimulation and longer follow-ups.

Aims: This study was aimed to produce biodegradable cellulose acetate films impregnated with bacteriocin-like inhibitory substances to be used in food packaging. Methodology and results: Bacterial isolates were isolated from different sources and tested for their antimicrobial activity by agar well diffusion assay. The isolate that showed the highest antimicrobial activity against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 51659, Pseudomonas aeruginosa MG847103 and Streptococcus mutans ATCC 25175 was identified as Lactiplantibacillus plantarum strain N1 (OM019104) based on 16S rRNA based method of identification. The extracted bacteriocin-like inhibitory substances were partially purified with acetone precipitation and SP-Sephroase cation exchange chromatography. There was no change in the antimicrobial activity after treatment with the catalase enzyme, but there was a total loss in the activity after treatment with proteolytic enzymes. The obtained bacteriocin-like inhibitory substances showed pH stability over a wide range of pH values and thermal stability as it recovered 95% of its antimicrobial activity even after autoclaving for 15 min. Different concentrations of cellulose acetate (3 to 12%) were tested to develop the active antimicrobial films. The most flexible concentrations for food packaging were prepared and impregnated with partially purified bacteriocin-like inhibitory substances. The prepared films showed promising antimicrobial activity against S. aureus. Conclusion, significance and impact of study This study highlights the usage of active packaging in food preservation. Cellulose acetate films activated with the partially purified bacteriocin-like inhibitory substances have anti-staphylococcal activity, which can potentially be used in food packaging to prolong the shelf-life of perishable foo

Effect of Change Angulation and Material of Mini-screw inserted in Retro Molar Pad Area on Stress Distribution: A Finite Element Simulation Study This study evaluated the influence of angulation and material composition on the stress distribution and displacement of mini-screws placed in the retromolar pad area using finite element analysis; these mini-screws inserted in the retromolar pad area were referred to as MRM. A 3D mandible model was generated from CT scan data using Mimics and 3-Matic software, while the mini-screw was modelled in AutoCAD. Finite element analysis was performed with Inventor Professional software. A 2 N force, parallel to the occlusal reference line (ORL), was applied to MRM at insertion angles of 0°, 15°, 30°, 45°, and 60° relative to the ORL. Three MRM materials were analysed: stainless steel (SS), titanium alloy (Ti-6Al-4V), and pure titanium (Ti). Results revealed that the lowest Von Mises stresses occurred at a 0° insertion angle, while the highest stresses were observed at 60°. Stress levels were comparable across materials at 0°, 15°, and 30°, but SS MRM generated higher stresses than titanium materials at 45° and 60°. Displacement analysis indicated that SS MRM had the lowest displacement, while Ti MRM exhibited the highest across all angles. Importantly, all stress values remained below the bone’s yield strength, and displacements were clinically insignificant. For optimal stability, a 0° insertion angle is recommended, with 15° and 30° serving as viable alternatives. These findings provide guidance on selecting mini-screw angulation and materials for effective orthodontic anchorage in the retromolar pad area.

This study investigated the effect of ethanol extracts of horsetail, alfalfa, ortie, chêne and aleppo oak on blood coagulation in vitro. Extraction was performed by the maceration method. Extracts were mixed with platelet and plasma, then prothrombin time (PT), activated partial thromboplastin time (APTT) and platelet aggregation tests were conducted. Alfalfa extract had a dose-dependent effect on the PT. Ortie, and horsetail, reduced the PT significantly compared to control group. Alfalfa, horsetail, and ortie reduced the APTT, but their effect was insignificant compared to the control group. The pooled extract showed the highest effect compared to the single extracts in a dose-dependent manner. Horsetail and alfalfa induced platelet aggregation in response to arachidonic acid but not in response to collagen. In the case of ortie, no aggregation occurred regarding the arachidonic acid, and incomplete was observed in response to collagen. Interestingly, blood clotting occurred immediately after adding the chêne, aleppo oak and the pooled extract, and therefore platelet poor plasma (PPP) and platelet rich plasma (PRP) became jelly. Generally, chêne and aleppo oak, as well as pooled extract, were more effective in inducing both primary and secondary coagulation pathways via shortening the PT and APTT, and induction of platelet aggregation.

Background: Migraine headaches have been associated with sensory hyperactivity and anomalies in social/emotional responses. The main objective of this study was to evaluate the potential involvement of orexin 1 receptors (Orx1R) within the basolateral amygdala (BLA) in the modulation of pain and psychosocial dysfunction in a nitroglycerin (NTG)-induced rat model of migraine. Methods: Adult male Wistar rats were injected with NTG (5 mg/kg, intraperitoneal) every second day over nine days to induce migraine. The experiments were done in the following six groups (6 rats per group): untreated control, NTG, NTG plus vehicle, and NTG groups that were post-treated with intra-BLA microinjection of Orx1R antagonist SB-334867 (10, 20, and 40 nM). Thermal hyperalgesia was assessed using the hot plate and tail-flick tests. Moreover, the elevated plus maze (EPM) and open field (OF) tests were used to assess anxiety-like behaviors. The animals’ sociability was evaluated using the three-chamber social task. The NTG-induced photophobia was assessed using a light-dark box. Results: We observed no change in NTG-induced thermal hyperalgesia following administration of SB-334867 (10, 20, and 40 nM). However, SB-334867 (20 and 40 nM) aggravated the NTG-induced anxiogenic responses in both the EPM and OF tasks. The NTG-induced social impairment was overpowered by SB-334867 at all doses. Time spent in the dark chamber of light-dark box was significantly increased in rats treated with SB-334867 (20 and 40 nM/rat). Conclusions The findings suggest a role for Orx1R within the BLA in control comorbid affective complaints with migraine in rats.

The severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which caused the coronavirus disease 2019(COVID-19)pandemic,has affected more than 400 million people worldwide.With the recent rise of new Delta and Omicron variants,the efficacy of the vaccines has become an important question.The goal of various studies has been to limit the spread of the virus by utilizing wireless sensing technologies to prevent human-to-human interactions,particularly for healthcare workers.In this paper,we discuss the current literature on invasive/contact and non-invasive/non-contact technologies(including Wi-Fi,radar,and software-defined radio)that have been effectively used to detect,diagnose,and monitor human activities and COVID-19 related symptoms,such as irregular respiration.In addition,we focused on cutting-edge machine learning algorithms(such as generative adversarial networks,random forest,multilayer perceptron,support vector machine,extremely randomized trees,and k-nearest neighbors)and their essential role in intelligent healthcare systems.Furthermore,this study highlights the limitations related to non-invasive techniques and prospective research directions.

Objectives: Fatigue is the most frequently reported symptom experienced by cancer patients and has a profound effect on their quality of life (QOL). The study aimed to determine the impact of fatigue on QOL among breast cancer patients receiving chemotherapy and to identify the risk factors associated with severe fatigue incidence. Methods: This was an observational prospective study carried out at multiple centers. In total, 172 breast cancer patients were included. The Functional Assessment of Chronic Illness Therapy-Fatigue Questionnaire was used to measure QOL, while the Brief Fatigue Inventory (BFI) was used to assess the severity of fatigue. Results: The total average mean and standard deviation of QOL were 84.58±18.07 and 4.65±1.14 for BFI scores, respectively. A significant association between fatigue and QOL was found in linear and multiple regression analyses. The relationships between fatigue severity and cancer stage, chemotherapy dose delay, dose reduction, chemotherapy regimen, and ethnicity were determined using binary logistic regression analysis. Conclusion The findings of this study are believed to be useful for helping oncologists effectively evaluate, monitor, and treat fatigue related to QOL changes.
