In recent years, there has been a significant interest in the advancement of electrochemical sensing platforms to detect antipyretic drugs with high sensitivity and selectivity. The electrochemical determination of acetaminophen (PCT) was studied with strontium molybdate with a functionalized carbon nanotube (SrMoO@f-CNF) nanocomposite. The SrMoO@f-CNF nanocomposite was produced by a facial hydrothermal followed by sonochemical treatment, resulting in a significant enhancement in the PCT determination. The sonochemical process was applied to incorporate SrMoO nanoparticles over f-CNF, enabling a network-like structure. Moreover, the produced SrMoO@f-CNF composite structural, morphological, and spectroscopic properties were confirmed with XRD, TEM, and XPS characterizations. The synergistic effect between SrMoO and f-CNF contributes to the lowering of the charge transfer resistance (Rct=85 Ω·cm2), a redox potential of Epc=0.15 V and Epa=0.30 V (vs. Ag/AgCl), and a significant limit of detection (1.2 nM) with a wide response range of 0.01-28.48 µM towards the PCT determination. The proposed SrMoO@f-CNF sensor was studied with differential pulse voltammetry (DPV) and cyclic voltammetry (CV) techniques and demonstrated remarkable electrochemical properties with a good recovery range in real-sample analysis.

BACKGROUND
Atypical acinar cell foci (AACF) seen in pancreatic cancer are fatal and have been studied with some causative agents. However, for the first time, the effect of acetylsalicylic acid with nitric oxide (NO-ASA) on AACF was examined in this study. Although NO-ASA has very successful inhibitory effects against some types of cancer, it has not been investigated whether they can exert their inhibition effects on AACFs.
METHODS
For experimental purposes, 21 14-day-old male Wistar albino rats were used. Azaserine (30 mg/kg) was dissolved in 0.9% NaCl solution and injected intraperitoneally (i.p.) into 14 rats, except for the Control group (Cont) rats, for three weeks. Rats that were injected with azaserine once a week for three weeks and those that did not receive treatment were divided into experimental groups. 15 days after the end of the azaserine injection protocol, NO-ASA was applied to azaserine with NO-ASA (Az+NO-ASA) group rats three consecutive times with an interval of 15 days by gavage. At the end of the 5-month period, pancreatic tissue was dissected and weighed. Pancreas preparations prepared from histological sections were examined for AACF burden and analyzed via a video image analyzer. One-way analysis of variance (ANOVA) non-parametric statistical analyses were performed to test whether there was a difference between the averages of the experimental and Control groups.
RESULTS
AACF burden in both groups injected with azaserine was found to be statistically significant in all categories compared to that of the Control group ( < 0.05). The average Calculated Estimated average AACF volume (mm) values, the Calculated estimated average AACF diameter (μm), the Estimated average number of AACF per unit volume, AACF rate as a % of Calculated Organ Volume were higher in the AzCont group rats than in the Az+NO-ASA group, when compared, and there was an important level statistical difference between the groups ( < 0.05). It was determined that for all parameters AACFs load in Az+NO-ASA group rats were significantly reduced compared to that of AzCont group rats ( < 0.05).
CONCLUSIONS
We observed that, as a result of the NO-ASA application, the experimental AACF focus ratio created by azaserine injection was significantly inhibited. The inhibitory effect of AACFs in Az+NO-ASA group rats may have resulted from the significant and independent chemopreventive and/or chemotherapeutic activity of NO-ASA against exocrine pancreatic AACF foci.

Effective monitoring of acetaminophen (APAP) dosage is crucial for preventing antipyretic abuse, ensuring therapeutic efficacy, and minimizing toxic effects. However, existing self-monitoring methods are limited. In this study, we designed a plasmonic microneedle (MN) sensor for real-time nondestructive monitoring of acetaminophen levels in dermal interstitial fluid (ISF) by employing a handheld Raman spectrometer. The fabricated MN sensor incorporated a high-density plasmonic MOFs known as HDPM, which unique structure of large specific surface area, specific pore structure as well as high density gold nanospheres packing enabled the excellent performance of selective ISF drug enrichment and surface-enhanced Raman scattering (SERS). The maximum electric field enhancement factor of the HDPM nanostructure could be calculated as 5.73 × 10. The developed HDPM@MNs was characterized with a core-shell type "soft on the outside and rigid on the inside" structure, which exhibited sufficient hardness and flexibility to penetrate the dermal tissue with little damage, and robust SERS enhancement effect in APAP detection without any interfering peaks. Through a hydrogel drug simulation experiment, the sensor demonstrated robust capabilities for acetaminophen enrichment and monitoring, exhibiting excellent stability and repeatability. The quantitative detection window spanned from 1 to 100 μM, with a low detection limit reaching 0.45 μM. Furthermore, by monitoring the concentration of acetaminophen in the interstitial fluid of rat skin at different doses and for different administration times, the HDPM@MNs can be used to determine the pharmacokinetics of acetaminophen in rats and the physiological characteristics associated with various dosage regimens. This work not only holds promise for drug monitoring but also provides a novel approach for nondestructive monitoring of other crucial low-abundance physiological markers.

AIM
The aim of this study was to investigate whether multimodal analgesia can decrease postoperative opioid usage in patients undergoing shoulder arthroscopy.
METHODS
Patients diagnosed with subacromial impingement syndrome who underwent acromioplasty at our institution between October 2022 and November 2023 were retrospectively analyzed. Patients were divided into an observation group and a control group based on postoperative pain management methods. The control group received intravenous self-controlled electronic analgesia (sufentanil injection 1 μg/kg + butorphanol injection 4 mg + 0.9% NaCl injection to 100 mL), while the observation group received multimodal analgesia (ropivacaine subacromial pump 3 mL/h, combined with oral celecoxib and acetaminophen). Visual Analog Scale (VAS) scores were recorded preoperatively and at various postoperative time points, and opioid usage, length of hospital stay, and analgesia-related complications within 1 week postoperatively were compared between groups. The 36-item Short Form Health Survey (SF-36) scores and the Constant-Murley score (CMS), were also assessed 1 day and 1 week after treatment.
RESULTS
One hundred thirty-two patients were included in the study, 66 in the observation group and 66 in the control group. In the control group, there were 46 males and 20 females, with a mean age of 55.47 ± 11.42 years and in the observation group 44 males and 22 females, with a mean age of 56.13 ± 12.19 years The observation group consistently reported significantly lower pain intensity compared to the control group at 8 h (T1), 24 (T2), and 48 h (T3) after surgery (p < 0.05). Additionally, the observation group exhibited significantly lower opioid usage and complication rates compared to the control group (p < 0.05). SF-36 scores and CMS scores were significantly higher in the observation group 1 week after treatment compared to the control group (p < 0.05).
CONCLUSIONS
Following shoulder arthroscopy, multimodal analgesia effectively reduces opioid consumption, lowers complication rates, and provides effective short-term pain relief. This approach carries significant implications for improving patient outcomes.

The objective of this study was to investigate the association between a Parkinson's disease (PD)-specific polygenic score (PGS) and protective lifestyle factors on age at onset (AAO) in PD. We included data from 4367 patients with idiopathic PD, 159 patients with GBA1-PD, and 3090 healthy controls of European ancestry from AMP-PD, PPMI, and Fox Insight cohorts. The association between PGS and lifestyle factors on AAO was assessed with linear and Cox proportional hazards models. The PGS showed a negative association with AAO (β = - 1.07, p = 6 × 10) in patients with idiopathic PD. The use of one, two, or three of the protective lifestyle factors showed a reduction in the hazard ratio by 21% (p = 0.0001), 44% (p < 2 × 10), and 55% (p < 2 × 10), compared to no use. An additive effect of aspirin (β = 7.62, p = 9 × 10) and PGS (β = - 1.58, p = 0.0149) was found for AAO without an interaction (p = 0.9993) in the linear regressions, and similar effects were seen for tobacco. In contrast, no association between aspirin intake and AAO was found in GBA1-PD (p > 0.05). In our cohort, coffee, tobacco, aspirin, and PGS are independent predictors of PD AAO. Additionally, lifestyle factors seem to have a greater influence on AAO than common genetic risk variants with aspirin presenting the largest effect.

Pharmaceutical formulations have traditionally relied on plants and their derivatives for various APIs and excipients. In Ghana, the widespread utilization of plantains, irrespective of their ripeness, generates significant waste at every stage of processing, posing disposal issues. Fascinatingly, these wastes, often discarded, possess significant economic potential and can be recycled into valuable raw materials or products. Pectin, a polysaccharide that occurs naturally, has seen a surge in interest in recent times. It has found widespread use in the pharmaceutical sector, particularly as a binding agent in tablet formulations. This study aimed to evaluate pectin from two popular plantain varieties, Apem (M) and Apantu (T) at different ripening stages, for pharmaceutical use as a binding agent in immediate-release tablets. The ripening stages selected were the matured-green (G), half-ripe (H), and full-ripe (R). Acid (D) and alkaline (L) mediums of extraction were employed for each ripening stage for both varieties. Wet granulation method was used to prepare the granules using paracetamol as a model drug, and their flow properties were subsequently assessed. Postcompression tests including, hardness, friability, weight uniformity, disintegration, assay, and in vitro dissolution were also assessed. Granules from all formulation batches had good flow properties indicated by their angle of repose (14.93 ± 1.41-21.80 ± 1.41), Hausner ratio (0.96 ± 0.27-1.22 ± 0.02), and compressibility (%) (7.69 ± 0.002-20.51 ± 0.002). All the tablets passed the uniformity of weight with none deviating by ±5%. The hardness of all the formulated tablets ranged between 3.96 ± 0.32 and 13.21 ± 0.36, while the friability for all tablets was below 1%. The drug content was between 100.1 ± 0.23% and 103.4 ± 0.01%. Tablets formulated with pectin as a binding agent at concentrations of 10% w/v and 15% w/v successfully met the disintegration test criteria for immediate release tablets. However, those prepared with a concentration of 20% w/v (MGL, MHD, MHL, MRD, MRL, TGL, THD, THL, and TRL) did not pass the disintegration test. Consequently, all batches of tablets successfully met the dissolution test requirement (Diss, > 75%), except for the batches that did not pass the disintegration test (Diss, < 75%). Ultimately, pectins extracted from the peels of Apem and Apantu at different ripening stages using acid and alkaline extraction can be commercially exploited as pharmaceutical binders at varying concentrations in immediate-release tablets.

Randomized Controlled Trial
INTRODUCTION
Even after the peak of the COVID-19 pandemic, the number of mild cases remains high, requiring continuous control. Curcumin, owing to its anti-inflammatory properties, can suppress vital proliferation and cytokine secretion in animal models. We developed a highly absorbable curcumin, curcuRouge (cR), which is approximately 100 times more orally bioavailable than conventional curcumin. We evaluated the effect of cR on the inhibition of disease progression in asymptomatic or mildly symptomatic COVID-19 patients.
METHODS
This study evaluated the effect of 7-day oral intake of cR (360 mg twice daily). Patients within 5 days of COVID-19 diagnosis were randomly assigned to a placebo or cR group in a double-blind manner.
RESULTS
Primary endpoint events [body temperature (BT) ≥ 37.5 °C and saturation of percutaneous oxygen (SpO2) < 96%] were fewer than expected, and the rate of these events was 2.8% in the cR group (2/71) and 6.0% in the placebo group (4/67); hazard ratio (HR) = 0.532, 95% confidence interval (CI) 0.097-2.902. Patients receiving cR tended to take fewer antipyretic medications than those receiving placebo (HR = 0.716, 95% CI 0.374-1.372). Among patients with a normal range of BT at baseline, the BT change rate was significantly (p = 0.014) lower in the cR group (- 0.34%) versus placebo (- 0.01%).
CONCLUSION
The relative suppression of event rates and antipyretic medications taken, and significant decrease of subclinical BT support the anti-inflammatory effects of cR in asymptomatic or mildly symptomatic patients with COVID-19.

Prevalence, practice, determinants and adverse effects of self-medication among young people living in a suburban community of Ekiti, Nigeria: A community-based cross-sectional study.
OBJECTIVES
Health hazards such as adverse drug reactions and prolonged morbidity are fallouts of self-medication among young people in sub-Saharan Africa. The aim of this study was to assess the prevalence, practice, determinants, and adverse effects of self-medication among young people living in a suburban community of Ekiti, Nigeria.
METHODS
This survey was a descriptive, cross-sectional study of 602 young people aged 16-24 years., who were randomly selected in the community. A predesigned self-administered questionnaire was used for data collection. The study was conducted from 1st March to 31st May 2023. The independent variables measured include the sociodemographic characteristics, while the dependent variables are the practice of self-medication and factors that predisposes to self-medication. The general characteristics of the participants were analyzed using descriptive statistics. The categorical variables were reported as frequency distribution and proportions with 95% confidence intervals and were compared using the Chi-square test or Fisher's exact test. A -value of <0.05 was considered statistically significant.
RESULTS
Over 30% (31.7%) of the participants engage in self-medication. A larger proportion of the people who practiced self-medication lived a trekking distance of less than 1 km from the nearest health facility with a doctor ( = 0.044). The practice of self-medication was statistically related with being a student when compared with gainfully employed and unemployed people ( = 0.006). Fever (39.8%), abdominal pain (17.3%) and headaches (16.2%) were the topmost three ailments that necessitated self-medication. Antimalarials (44.0%), antibiotics (25.1%), and antipyretics (16.8%) were high on the list of drugs used for self-medication. Headache (34.0%) was the most common adverse reaction from self-medication among the participants studied.
CONCLUSION
Adverse reactions and drug addiction were negative fallouts of self-medication, which can affect the health of young people as they grow into adulthood. Therefore, monitoring of drug outlets must be taken seriously by government agencies to prevent the worsening of the negative effects of self-medication.

Acetaminophen is a commonly used analgesic and antipyretic drug, which has experienced an increase in its consumption in recent years in our environment. There has also been an increase in the number of accidental and intentional overdoses that were treated by the health system. Its toxicity is dose-dependent and can cause fulminant liver failure, becoming one of the main reasons for liver transplantation in English-speaking countries. The case of a 28-year-old woman with a history of major depression and five previous suicide attempts, who deliberately ingested a significant amount of paracetamol tablets, is here presented. She developed fulminant liver failure and metabolic acidosis, for which she underwent an emergency liver transplant due to the severity of her condition, from which she evolved favorably. The decision to perform a liver transplant in serious cases like this and under a condition of severe psychiatric vulnerability is challenging and must be carefully considered. This particular case illustrates the importance of multidisciplinary care including psychiatric evaluation in patients with acetaminophen poisoning.
