Dual antiplatelet including clopidogrel and aspirin, cardiac MRI, and speckle tracking echocardiography parameters in ST-elevation myocardial infarction patients

Coronary artery disease is the medical term for atherosclerotic coronary disease, which causes the coronary arteries to constrict and inadequately provide blood to the heart. ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, & unstable angina are the three conditions that comprise acute coronary syndromes. Studied cases with STEMI have been advised to take several drugs in addition to early reperfusion treatment, such as antiplatelet & anticoagulant medications. The goal of antiplatelet medications is to stop platelets from aggregating together. Oral dual antiplatelet medication, which combines lifetime aspirin with an oral P2Y12 receptor inhibitor, is the main antiplatelet therapy in STEMI. Aspirin ought to be administered to all studied cases immediately following diagnosis, and a low dose of treatment should be continued indefinitely. Heart mortality and severe adverse cardiac events are strongly and independently correlated with the presence & size of scarred tissue seen by cardiac MRI. Scar transmurality measured by cardiac MRI in studied cases with healed infarcts & ventricular dysfunction predicts patient survival and functional recovery following revascularization. Patients with heart illnesses that have a history of ST-segment elevation myocardial infarction may be at risk for unfavorable results based on echocardiographic evaluation of cardiac structure & function. Because speckle tracking echocardiography (STE) is quick and simple to do, it can be used in acute settings as well. It can be used for further risk stratification following revascularization, before invasive coronary angiography, or in cases when a diagnosis is unclear, if available.

Recent developments in the field of radiotherapy for the management of lung cancer.

Lung cancer has a poor prognosis, and further improvements in outcomes are needed. Radiotherapy plays an important role in the treatment of unresectable lung cancer, and there have been recent developments in the field of radiotherapy for the management of lung cancer. However, to date, there have been few reviews on the improvement in treatment outcomes associated with high precision radiotherapy for lung cancer. Thus, this review aimed to summarize the recent developments in radiotherapy techniques and indicate the future directions in the use of radiotherapy for lung cancer. Stereotactic body radiotherapy (SBRT) for unresectable stage I lung cancer has been reported to improve local control rates without severe adverse events, such as radiation pneumonitis. For locally advanced lung cancer, a combination of chemoradiotherapy and adjuvant immune checkpoint inhibitors dramatically improves treatment outcomes, and intensity-modulated radiotherapy (IMRT) enables safer radiation therapy with less frequent pneumonitis. Particle beam therapy, such as carbon-ion radiotherapy and proton beam therapy, has been administered as advanced medical care for patients with lung cancer. Since 2024, it has been covered under insurance for early stage lung cancer with tumors ≤ 5cm in size in Japan. In addition to chemotherapy, local ablative radiotherapy improves treatment outcomes in patients with oligometastatic stage IV lung cancer. A particular problem with radiotherapy for lung cancer is that the target location changes with respiratory motion, and various physical methods have been used to control respiratory motion. Recently, coronavirus disease has had a major impact on lung cancer treatment, and cancer treatment during situations, such as the coronavirus pandemic, must be performed carefully. To improve treatment outcomes for lung cancer, it is necessary to fully utilize evolving radiotherapy modalities, and the role of radiotherapy in lung cancer treatment is expected to increase.

Adverse event signal mining and severe adverse event influencing factor analysis of Lumateperone based on FAERS database.

Lumateperone has been approved by the Food and Drug Administration (FDA) for the treatment of schizophrenia in adults since 2019, however, there is still a lack of data report on adverse reactions in real-world settings. Conducting data mining on adverse events (AEs) associated with Lumateperone and investigating the risk factors for serious AEs can provide valuable insights for its clinical practice. AE reports in the FDA Adverse Event Reporting System (FAERS) from 2019 Q4 (FDA approval of Lumateperone) to 2024 Q1 were collected and analyzed. Disproportionality in Lumateperone-associated AEs was evaluated using the following parameters: Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-item Gamma Poisson Shrinker (MGPS). Univariate and multivariate logistic regression analyses were conducted to identify the risk factors for Lumateperone-induced severe AEs. A total of 2,644 reports defined Lumateperone as the primary suspected drug was collected, including 739 reports classified as severe AEs and 1905 reports as non-severe AEs. The analysis revealed that 130 preferred terms (PTs) with significant disproportionality were based on the four algorithms, 67 (51.53%) of which were not included in the product labeling, affecting 6 systems and organs. In addition, dizziness (81 cases) was the most reported Lumateperone-associated severe AEs, and tardive dyskinesia showed the strongest signal (ROR = 186.24). Logistic regression analysis indicated that gender, bipolar II disorder, and concomitant drug use are independent risk factors for Lumateperone-associated severe AEs. Specifically, female patients had a 1.811-fold increased risk compared with male patients (OR = 1.811 [1.302, 2.519], p = 0.000), while patients with bipolar II disorder had a 1.695-fold increased risk compared with patients diagnosed with bipolar disorder (OR = 1.695 [1.320, 2.178], p = 0.000). Conversely, concomitant use of CYP3A4 inhibitors or drugs metabolized by CYP3A4 was associated with a decreased risk of severe AEs (OR = 0.524 [0.434, 0.633], P = 0.000). Collectively, this study provides critical insights into the safety profile of Lumateperone. It highlights the need for cautious use in high-risk populations, such as females and individuals with bipolar II disorder, and emphasizes the importance of monitoring for AEs, including dizziness and tardive dyskinesia. Healthcare also should remain alert to potential AEs not listed in the prescribing information to ensure medical safety.

Clinical Features, Adverse Events and Treatment Outcomes of Multidrug/Rifampicin-resistant Tuberculosis in Children and Adolescents: An Eight-year Retrospective Cohort Study in Bandung, Indonesia.

Data on childhood and adolescent multidrug/rifampicin-resistant tuberculosis (MDR/RR-TB) in Indonesia are lacking. We aimed to assess clinical features, adverse events (AEs) and treatment outcomes of childhood and adolescent MDR/RR-TB. A retrospective cohort study was performed in children and adolescents aged <18 years treated for MDR/RR-TB at Hasan Sadikin General Hospital in Bandung, Indonesia, between June 2016 and March 2024. Multivariable logistic regression analyses were used to calculate adjusted odds ratios (aOR) for predictors of all-cause mortality. Among 84 included patients, 69 (82%) were adolescents aged 10-17 years, 54 (64%) were female, 54 (64%) were malnourished and 55 (65%) had culture-confirmed disease. Among 69 (82%) patients with known outcomes, 48 (70%) were successfully treated, 14 (20%) died (including 5 pretreatment deaths) and 7 (10%) were lost to follow-up (LTFU) (including 5 pretreatment LTFU). Predictors of all-cause mortality included shortness of breath on admission [aOR: 6.4, 95% confidence interval (CI): 1.3-49.1], high bacillary burden on Xpert MTB/RIF assay (aOR: 17.0, 95% CI: 1.6-260.5) and the presence of lung cavities on chest radiograph (aOR: 4.8, 95% CI: 1.1-23.3). Among 74 patients who initiated treatment, 39 (53%) had at least one grade 1-2 AE, and 4 (5%) had one grade 3-4 AE each, including hepatotoxicity, QT prolongation, hearing loss and rash/hyperpigmentation. Younger children were underrepresented among those treated for MDR/RR-TB, indicating reduced access to care. Severe AEs were uncommon during MDR/RR-TB treatment. Baseline indicators of extensive disease were associated with all-cause mortality. The high proportion of pre-treatment mortality and LTFU may reflect complex patient pathways limiting access to care.

Neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy for initially unresectable locally advanced colon cancer: short-term outcomes of an open-label, single-centre, randomised, controlled, phase 3 trial

Neoadjuvant chemotherapy (NACT) is commonly used to downstage the tumor in locally advanced colon cancer (LACC) and improve the R0 resection rate. Neoadjuvant chemoradiotherapy (NACRT) is the standard treatment for locally advanced rectal and esophageal cancers, but its benefits in LACC remain poorly understood. This study aimed to compare the effects and safety of NACRT and NACT on R0 resection and survival rates in initially unresectable LACC. This was an open-label, single-center, randomized, controlled trial conducted between May 11, 2019 and May 30, 2022. Forty-five patients with initially unresectable LACC were randomly allocated to the NACT (control, n=20) or NACRT (research, n=25) group. The NACT group received XELOX (oxaliplatin 100-130mg/m2, qd, d1, every 3 weeks; and capecitabine 1000mg/m2, bid, d1-d14, every 3 weeks) for 4 cycles. The NACRT group, in addition to chemotherapy, received daily irradiation (GTV 45-50Gy/25F; CTV 42.5-45Gy/25F). Surgery was scheduled 6-12 weeks after neoadjuvant treatment and adjuvant chemotherapy was administered if the patient developed resectable LACC. The primary endpoint was the 5-year overall survival (OS) rate. The secondary outcomes included the 3-year progression-free survival (PFS) and R0 resection rates. This study was registered with ClinicalTrials.gov (NCT03970694). In short-term outcome analysis, NACRT significantly improved the R0 resection rate (80% for NACRT vs. 20% for NACT, P<0.001). The NACRT and NACT groups had a 3-year OS of 87.6% and 75% (P=0.037) and a 3-year PFS of 76% and 45% (P=0.049), respectively. The 5-year OS was not reached. In the NACRT group, no local or regional recurrence was observed in patients who underwent surgery during the follow-up period, compared to two patients in the NACT group. Both NACT and NACRT were well tolerated, with no significant differences in severe adverse events. The most commonly observed grade 3-4 AE was myelosuppression (39% for NACRT and 47% for NACT, P=0.609). No grade 5 AEs were observed between the two groups. Adding radiation to NACT increased the R0 resection rate, prolonged the PFS, and potentially improved OS in selected patients with initially unresectable LACC. The trial findings indicate that this approach is safe, feasible, and may confer a survival benefit.

Effective Treatment of Primary Orbital Squamous Cell Carcinoma with Radiotherapy: A Rare Case Report and Literature Review Update

AbstractPrimary squamous cell carcinoma (SCC) of the orbit is exceptionally rare, comprising only a small fraction of ocular tumours, with most cases being secondary to tumours originating from nearby structures or due to distant metastasis. We present a case of primary orbital SCC in a 60-year-old male, discussing its diagnostic workup, imaging findings, and multidisciplinary management. The patient underwent definitive radiotherapy with concurrent chemotherapy after being deemed inoperable. Without any severe treatment-related adverse event, the patient achieved a complete metabolic response at 7 months post-treatment with maintained vision. As evident from a review of the literature, treatment approaches vary widely in this group of patients, with radiotherapy emerging as a successful modality in achieving disease control while preserving vision with acceptable toxicity. This case underscores the complexity of managing primary orbital SCCs and highlights the efficacy of radiotherapy in achieving favourable outcomes.

Tolerability and Safety of Miltefosine for the Treatment of Cutaneous Leishmaniasis.

Miltefosine, an orally administered drug, is an important component of the therapeutic arsenal against visceral and mucosal forms of leishmaniasis. However, data regarding the safety and tolerability of miltefosine treatment for cutaneous leishmaniasis (CL) are relatively limited. The aim of this study was to evaluate the tolerability, safety, and adverse events (AEs) of miltefosine treatment in patients with CL. In this cohort study, we reviewed the medical records of all miltefosine-treated patients between 1 January 2016 and 31 December 2022, at Israel Defense Forces military dermatology clinics and the dermatology and Tropical Medicine Clinics at Chaim Sheba Medical Center, Ramat-Gan, Israel. A total of 68 patients (54 males, 79%) with a median age of 30.3 ± 15.6 years (range: 18-88) were included in this study. Leishmania species were identified as L. major (n = 37, 54.4%), L. tropica (n = 12, 17.6%), L. braziliensis (n = 18, 26.5%), and L. infantum (n = 1, 1.5%) using polymerase chain reaction (PCR). Miltefosine tablets were administered orally at a dose of 50 mg, three times daily, for 28 days. Overall, 44 patients (65%) completed the 28-day treatment, and the remaining patients required dose reduction or early discontinuation of treatment. AEs (of any degree) were common, reported in 91% of patients. Both previously reported and previously unreported AEs were documented. Gastrointestinal symptoms (66.1%) and malaise (23.5%) typically occurred during the first two weeks of treatment and tended to subside. Other AEs, including acute renal failure (20.6%), sudden and severe pleuritic chest pain (7.6%), acne exacerbation (11.8%), suppuration of CL lesions (17.8%), and AEs related to the male genitourinary system (39.6% of males), typically occurred towards the end of treatment. The latter included testicular pain, epididymitis, diminution or complete absence of ejaculate, inability to orgasm, and impotence. Severe AEs necessitated treatment discontinuation (29.4%) or hospitalization (10.3%). URTI-like symptoms, arthritis, cutaneous eruption, pruritus, and laboratory abnormalities were also observed. Overall, the cure rate (for all patients combined) evaluated 3 months after the completion of treatment was 60%. The tolerability of miltefosine treatment for CL is low. Close clinical and laboratory monitoring is required during treatment, as severe AEs are not uncommon. As new insights regarding its toxicities emerge, further studies are required to define the role of miltefosine in the treatment of CL.

Post-marketing safety concern of PI3K inhibitors in the cancer therapies: an 8-year disproportionality analysis from the FDA Adverse Event Reporting System

ABSTRACT Background The Phosphoinositide 3-kinases (PI3Ks) family plays a crucial role in tumorigenesis. Alpelisib (inhibiting PI3Kα), copanlisib (inhibiting PI3Kα andPI3Kδ), duvelisib (inhibiting PI3Kδ and PI3Kγ), and idelalisib (inhibiting PI3Kδ) were developed to target the PI3K pathway. However, the toxicity limits their application to some extent. It’s necessary to investigate the adverse effects (AEs) of these inhibitors. Research design and methods We conducted a comparative analysis of the safety signals of AEs in PI3K inhibitors using disproportionality analysis in the FDA Adverse Event Reporting System database(FAERS). Results Our study identified significant safety signals for metabolic disorders with all PI3K inhibitors. Notable safety signals for gastrointestinal disorders were observed with most PI3K inhibitors, with the exception of copanlisib. Common AEs shared among all PI3K inhibitors included colitis and dehydration. Alpelisib displayed unique AEs associated with metabolic disorders, whereas copanlisib exhibited idiosyncratic AEs linked to cardiac and vascular disorders. Stevens-Johnson syndrome emerged as a common severe adverse event (SAE) among alpelisib, copanlisib, and idelalisib, while febrile neutropenia was prevalent among copanlisib, duvelisib, and idelalisib. Intestinal perforation was solely associated with alpelisib. Conclusions The safety profiles of the five PI3K inhibitors vary concerning adverse events. These findings could guide drug selection and inform future prospective research.

Buprenorphine: Opioid Agonist-Antagonist for Refractory Pain of Sickle Cell Disease Patients During Hematopoietic Stem Cell Transplant, Uncontrolled By Full-Agonist Opioids.

Bone marrow transplant (BMT) offers potential cure for cancer and a spectrum of otherwise incur- able diseases. The BMT process can cause multi-systemic pain in patients with sickle cell disease (SCD) refractory to high-dose opioid analgesics during BMT because of their pre-existing opioid-tolerance. Because of frequent pain resulting in hyperalgesia and chronic opioid use, SCD patients undergoing BMT often experience excruciating pain uncontrolled by exceedingly high-dose opioids with severe and intolerable adverse effects. There is a small but growing body of literature about the successful buprenorphine effect for SCD's chronic pain management that had failed sufficient pain relief by the traditional full-agonist opioids in the outpatient setting. However, the buprenorphine use for acute inpatient pain management has not been previously researched. Pilot prospective clinical trial with buprenorphine-based pain management for acute BMT-related pain was initiated for SCD patients' pain uncontrolled by full-agonist opioids. Procedures/data/observations: Buprenorphine was started as scheduled and as-needed analgesics, supplemented by full-agonist opioids upon consultation for uncontrolled BMT-related pain of SCD patients. Patients' 24-hour opioid requirement by morphine equivalent daily doses (MEDD) were assessed at 3 time points: 1)immediately before pain escalation; 2)consultation; 3)discharge. MEDDs were compared to those of patients treated with full-agonist opioids only. Cases treated by full-agonist opioids (morphine/hydromorphone/fentanyl/methadone/oxycodone) had MEDD escalation by 1230-16300% by discharge compared to immediately before BMT-related pain escalation. Buprenorphine-supported cases had significantly smaller MEDD increase by 220-317%. Our case series suggests superior pain control by adding Buprenorphine prior to opioid dose escalation during BMT for SCD. Buprenorphine may provide the advantageous effect for other patients with complex pain background and experiencing difficult pain management during BMT due to pre-existing hyperalgesia and high opioid-tolerance. The evidence for buprenorphine's analgesic effect is moderate but growing, and more randomized controlled trials comparing the buprenorphine and other standard opioids are needed.

Severe exacerbation of facial dermatitis with swelling following introduction of abrocitinib in a patient with atopic dermatitis

BackgroundAbrocitinib, an oral small-molecule Janus kinase 1 (JAK1) inhibitor, has been widely accepted for the treatment of moderate-to-severe atopic dermatitis (AD). Currently there is a paucity of data on the adverse events (AEs) after abrocitinib treatment, especially on rare events such as exacerbation of facial dermatitis, and their causal relationship and subsequent management remains poorly elucidated.Case presentationA 43-year-old female patient with moderate AD received dupilumab after failure of topical treatments. Facial dermatitis persisted and became refractory after dupilumab treatment, and the patient changed treatment to oral abrocitinib. Fifteen hours after the first dose of abrocitinib, she developed exacerbation of facial dermatitis with swelling. The patient was initially diagnosed as abrocitinib-induced hypersensitivity. However, a score of 3 of the Naranjo adverse drug reaction assessment indicates week correlation between abrocitinib therapy and exacerbation of facial dermatitis, and negative results from subsequent drug provocation test further suggests no causal relationship.ConclusionsThe present case report highlights the necessity of careful determination of abrocitinib-induced hypersensitivity, which should not be diagnosed simply based on the time sequence between drug exposure and symptom occurrence. In addition, caution should be exercised for drug withdrawal, especially when confirmative evidence is absent. Drug provocation test can be helpful and effective treatments could be continued unless severe AEs occur.

Unilateral Magnetic Resonance-Guided Focused Ultrasound Lesion of the Subthalamic Nucleus in Parkinson's Disease: A Prospective Study.

Unilateral subthalamic nucleus (STN) ablation using magnetic resonance-guided focused ultrasound (MRgFUS) is being explored as a new treatment for asymmetric Parkinson's disease (PD). The aims were to study the efficacy and safety of this treatment in asymmetric PD patients and to characterize the lesions. This prospective, single-center, open-label study evaluated asymmetric PD patients at 6 (n = 20) and 12 months (n = 12) after MRgFUS lesion of the STN. The primary outcome was the change in the Movement Disorders Society-Unified Parkinson's Disease Rating Scale, Part III (MDS-UPDRS III), score in off medication on the treated side and the adverse events (AEs) at 6-month follow-up. We also evaluated cognitive-neuropsychological changes, self-assessment of clinical improvement, and the correlation of the lesion volume with the motor outcomes. On the treated side, the MDS-UPDRS III score (mean difference = 13.8) and the scores in rigidity, bradykinesia, and tremor improved (P < 0.001) throughout the follow-up compared to baseline (at 6 months: rigidity mean difference = 2.8, improvement: 83.5%; bradykinesia mean difference = 6.0, improvement: 69.4%; tremor mean difference = 4.7, improvement: 91.5%). One patient had severe weakness in the treated hemibody, 1 had moderate dyskinesia, and 1 was in moderate confusional state that became mild (weakness) or completely resolved (dyskinesia and confusional state) at 6 months. The rest of the AEs were mild. We observed no clinically relevant changes in cognitive-neuropsychological tests. The percentage of ablation of the STN correlated with the improvement in the total MDS-UPDRS III and contralateral tremor scores (P < 0.05). Unilateral MRgFUS lesion of the STN resulted in a significant motor improvement. We observed no persistent severe AEs, although mild, mostly transient AEs were frequent. © 2024 The Author(s).

FSCIG 10% in pediatric primary immunodeficiency diseases: a European post-authorization safety study

BackgroundThe safety, tolerability, and immunogenicity of hyaluronidase-facilitated subcutaneous immunoglobulin (fSCIG) 10% (dual-vial unit of human immunoglobulin 10% and recombinant human hyaluronidase [rHuPH20]) were assessed in children with primary immunodeficiency diseases (PIDs).MethodsThis phase 4, post-authorization, prospective, interventional, multicenter study (NCT03116347) conducted in the European Economic Area, enrolled patients aged 2 to < 18 years with a documented PID diagnosis who had received immunoglobulin therapy for ≥ 3 months before enrollment. New fSCIG 10% starters underwent fSCIG 10% dose ramp-up for ≤ 6 weeks (epoch 1) before receiving fSCIG 10% for ≤ 3 years (epoch 2); patients pretreated with fSCIG 10% entered epoch 2 directly. The primary outcome was the number and rate (per infusion) of all noninfectious treatment-related serious and severe adverse events (AEs).ResultsIn total, 42 patients were enrolled and dosed (median [range] age: 11.5 [3–17] years; 81% male; 23 new starters; 19 pretreated). Overall, 49 related noninfectious, treatment-emergent AEs (TEAEs) were reported in 15 patients; most were mild in severity (87.8%). No treatment-related serious TEAEs were reported. Two TEAEs (infusion site pain and emotional distress) were reported as severe and treatment-related in a single new fSCIG 10% starter. The rate of local TEAEs was lower in pretreated patients (0.1 event/patient-year) versus new starters (1.3 events/patient-year). No patients tested positive for binding anti-rHuPH20 antibodies (titer of ≥ 1:160).ConclusionsNo safety signals were identified, and the incidence of local AEs declined over the duration of fSCIG 10% treatment. This study supports fSCIG 10% long-term safety in children with PIDs.Trial registration number (ClinicalTrials.gov)NCT03116347.

Copper Phthalocyanine for Designing a Highly Selective and Disposable Electrochemical Volatile Organic Compound (VOC) Sensor

Formic acid (FA) is one of the very important organic acids that has been widely used in various industries. The highly corrosive FA can have severe adverse effects on the surrounding environment. Here, we developed an electrochemical sensor that utilizes the material properties of multi‐walled carbon nanotubes (MWCNTs), and copper phthalocyanine (CuPc) for the real‐time detection of FA gas. The response of FA has been compared with the responses of 9 common volatile organic compounds (VOCs). The chronoamperometry (CA) results revealed a high selectivity towards FA by showing an increase in the sensor current by about 25%, in contrast to the decrease of the current in response to the other VOCs. The sensitivity of the CuPc device to FA was calculated to be 38.85 mAM‐1. Material characterization (SEM, EDX, FTIR, Raman, and UV‐vis) also strongly suggests a protonation mechanism caused by the carboxylic acid group, which enhances the electrical conductivity.

Stepwise dual-target magnetic resonance-guided focused ultrasound in tremor-dominant Parkinson disease: One-year follow-up.

Magnetic resonance-guided focused ultrasound (MRgFUS) is a nonsurgical treatment for Parkinson disease (PD). Some selected anatomical structures can be targeted by MRgFUS in PD. However, there is no uniform target yet. We have reported that stepwise dual-target MRgFUS was successfully applied to treat refractory tremors with akinetic-rigid features in PD. It generated two precise thermal ablations in the ventral intermediate nucleus (VIM) and pallidothalamic tract (PTT). Here, we report more PD patients to verify the safety and efficacy of stepwise dual-target MRgFUS. Ten tremor-dominant PD patients (mean age = 66.7 ± 3.2 years, eight men) received the stepwise dual-target MRgFUS treatment with a series of primary and secondary outcome measures. The VIM and PTT were navigated based on brain magnetic resonance images. Outcome measures were categorized into primary and secondary assessments. The primary outcome measures consisted of resting tremor, action/kinetic tremor, rigidity, and bradykinesia. Secondary outcome measures encompassed non-motor symptoms scale of PD. Data collected at follow-up time points, including 1 day, 3 months, 6 months, and 1 year posttreatment, were compared with baseline data. The severity of tremor and motor deficits represented by Clinical Rating Scale for Tremor parts A and B during off-medication status and Unified Parkinson's Disease Rating Scale III on the treated side were significantly improved (p < 0.05 by paired t-test) at 1-year follow-up. At the 1-year follow-up, significant improvement was observed in the non-motor symptoms scale. Additionally, no severe adverse effects were reported, except temporary treatment-related discomfort during the procedure. In conclusion, stepwise dual-target MRgFUS emerges as a safe and effective therapeutic modality for PD patients, particularly in addressing medication-refractory tremor and akinetic-rigid syndrome.

Unraveling the Mechanisms of MicroRNA in Suppressing Hepatitis B Virus Progression: A Comprehensive Review for Designing Treatment Strategies

: Liver cancer and cirrhosis caused by the Hepatitis B virus (HBV) remain significant global health challenges due to the virus's high prevalence and contagious nature. Hepatitis B virus can be transmitted through various means, leading to mild or severe liver disease. Although an effective prophylactic vaccine is available, it offers limited benefits for those already chronically infected. Current treatments often fail to consistently eliminate the virus and can cause severe adverse effects. In response to these challenges, researchers have begun exploring microRNAs (miRNAs) as novel therapeutic targets. Studying miRNA-virus interactions presents a promising opportunity to identify potential therapeutic targets. By manipulating host miRNAs, researchers aim to enhance antiviral defenses, restore cellular balance, and prevent viral replication. The text concludes by highlighting the potential for personalized medicine in Hepatitis B treatment, guided by individual miRNA profiles. Numerous studies have been conducted to understand how different miRNAs inhibit HBV replication, paving the way for the development of innovative and effective therapeutic strategies.

Stapfer I and II duodenal perforations after endoscopic procedures: how surgical delay impacts outcomes.

Post-endoscopic duodenal perforation is a severe adverse event with high morbidity and mortality rates. Managing this rare event is challenging owing to limited clear guidelines. This retrospective study aimed to examine the relationship between time-to-treatment and morbidity among patients with post-endoscopic duodenal perforations. Over 20years, 78 consecutive patients with post-endoscopic duodenal perforations were analyzed. Among these, most patients underwent endoscopic procedures at the Paoli-Calmettes Institute, whereas some were referred from other centers after a diagnosis of perforation. We described the characteristics of patients who underwent medical treatment alone or interventional procedures. Among patients who underwent interventional management, we compared the outcomes following early or delayed procedures (later than 24h post-duodenal perforation diagnosis). Overall, 78 patients with post-endoscopic duodenal perforation were identified between September 2003 and September 2022. Of these, 17 (22%) patients underwent non-operative management, and 61 (78%) with peritonitis or adverse clinical features were treated with endoscopic or surgical procedures. Additionally, among these patients, 40 (65%) underwent immediate invasive procedures, surgically (n = 20) or endoscopically (n = 20). Patients with delayed procedures experienced more major Clavien-Dindo ≥ 3 complications and had an increase by 21 of the median comprehensive complication index. Overall, mortality occurred in 7 (8.9%) patients in the entire cohort and in 3 (14.3%) with delayed invasive procedures. Delayed decision-making is a key factor complicating post-endoscopic duodenal perforation. Therefore, invasive procedures should be performed promptly in cases of adverse conditions requiring additional procedures, ideally within the first 24h of perforation diagnosis.

AYURVEDIC MANAGEMENT OF KSHEENA SHUKRA (OLIGOSPERMIA) LEAD-ING TO MALE INFERTILITY: A CASE STUDY

As per the World Health Organization (WHO) report in India, the overall prevalence of primary infertility ranges between 3.9 and 16.8%. A recent report on the status of infertility states that 50% of it is related to productive anomalies or disorders in males. In comparison, 90% of male infertility problems are related to Oligospermia and other abnormalities in semen analysis. As per Ayurveda, Oligospermia can be considered as Ksheena Shukra (Oligospermia). Surgery, Hormone treatments, medications and Assisted Reproductive Technology (ART) are the main lines of treatment in Conventional medicine, but these are associated with many unwanted and severe adverse effects. The present case discussion is about effectively managing a case diagnosed as Ksheena Shukra with Ayurvedic intervention. This case report aims to evaluate the effect of Ayurvedic treatment in managing Ksheena Shukra. In this case study, Shodhana (Purificatory Therapy) procedures {especially Virechana Karma (Purgation) and Vasti(Enema)} were performed before administering Rasayana (Rejuvenation) drugs; the pre- and postsemen analysis during the treatment period shows a marked increase in sperm count and motility. The outcome of this case reveals that Ayurvedic treatments can effectively manage the Oligospermia associated with male infertility.

Electrospun patches to deliver combination drug therapy for fungal infections

Fungal infections, though affecting healthcare globally, receive insufficient attention in clinical and academic settings. Invasive fungal infections, particularly caused by combat wounds, have been identified as a critical threat by the US Department of Defense. Monotherapy with traditional antifungals is often insufficient, and so combination therapies are explored to enhance treatment efficacy. However, systemic combination treatments can result in severe adverse effects, suggesting the need for localised delivery systems, such as drug-loaded electrospun patches, to administer antifungals directly to the infection site. This proof-of-concept study hypothesised that dual amorolfine and terbinafine therapy slowly releasing from electrospun patches would be an effective way of eradicating Candida albicans when the patch was applied directly to the fungal colony. The feasibility of creating electrospun materials loaded with amorolfine and terbinafine for combination antifungal therapy was investigated. Electrospinning was used to fabricate polycaprolactone (PCL) patches with varying drug loadings (2.5%, 5%, and 10% w/w) of amorolfine and terbinafine either individually or in combination. The incorporation of both drugs in the fibres was confirmed, with the drugs predominantly in an amorphous state. Results showed that combination therapy patches had a significantly greater and prolonged antifungal effect compared to monotherapy patches, with larger zones of inhibition and sustained efficacy over at least 7 days. This study therefore demonstrates that PCL-based electrospun patches containing amorolfine and terbinafine provide superior antifungal activity against C. albicans compared to monotherapy patches. This approach could lower required drug doses, reducing adverse effects, and enhance patient compliance due to prolonged drug release, leading to more effective antifungal therapy.

Artemisinin conferred cytoprotection to human retinal pigment epithelial cells exposed to amiodarone-induced oxidative insult by activating the CaMKK2/AMPK/Nrf2 pathway

BackgroundOcular toxicity is a severe adverse effect that limits the chronic clinical use of the antiarrhythmic drug amiodarone. Here, we aimed to evaluate the cytoprotective effect of artemisinin and explore the potential signalling pathways in human retinal pigment epithelial (RPE) cell cultures.MethodsD407 cell cultures were exposed to amiodarone and the impact of artemisinin was evaluated. The key parameters included lactate dehydrogenase (LDH) release, intracellular reactive oxygen species (ROS) generation, and the mitochondrial membrane potential (MMP). We also assessed the protein levels of cleaved caspase-3, cleaved poly (ADP-ribose) polymerase (PARP), phosphorylated adenosine monophosphate-activated protein kinase (AMPK)ɑ (p-AMPK), calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2), and nuclear factor erythroid 2-related factor 2 (Nrf2).ResultsArtemisinin reduced the cytotoxicity induced by amiodarone, as reflected by decreased LDH release, ROS generation, and MMP disruption. Additionally, artemisinin increased p-AMPK, CaMKK2, and Nrf2 protein levels. Inhibition of AMPK, CaMKK2, or Nrf2 abolished the cytoprotective effect of artemisinin. AMPK activation and Nrf2 knockdown further supported its protective role.ConclusionsArtemisinin protected RPE cells from amiodarone-induced damage via the CaMKK2/AMPK/Nrf2 pathway. The in vivo experiments in mice confirmed its efficacy in preventing retinal injury caused by amiodarone. These results suggest that an artemisinin-based eye formulation could be repurposed for treating amiodarone-induced ocular toxicity.

Implementing stereotactic arrhythmia radioablation with STOPSTORM.eu consortium support: intermediate results of aprospective Israeli single-institutional trial.

Ventricular tachycardia (VT) is alife-threatening arrhythmia originating from the heart's ventricles. Traditional treatments include antiarrhythmic medications, implantable cardioverter-defibrillators (ICDs), and catheter ablation. Stereotactic body radiation therapy (SBRT) targeting the arrhythmogenic focus in the left ventricle-stereotactic arrhythmia radioablation (STAR)-is an emerging treatment and may offer apotential solution for patients with refractory VT. We designed an interventional prospective clinical trial in Israel aligned with the STOPSTORM.eu consortium's benchmarks, recommendations, and directives to assess the safety and efficacy of STAR in patients with refractory VT. Our phaseI/II single-institutional trial was approved by the Ministry of Health of Israel for 10patients, initially assessing safety in the first 3patients. We included patients with ICDs experiencing symptomatic monomorphic VT after an inadequate response to previous therapies. The primary endpoints were treatment-related serious adverse events and areduction in VT burden as assessed by ICD interrogation. Secondary outcomes included areduction in antiarrhythmic medications and changes in quality of life. From August 2023 to August 2024, 3patients underwent STAR treatment. The prescription dose was asingle fraction of 25 Gy. Planning target volumes were 47.8, 49.7, and 91.8 cc, and treatment was successfully delivered with no grade3 or higher adverse events reported. Over afollow-up period of 12months for the first patient and 8months for the second one, no VT events were recorded after treatment. The third patient died from progressive heart failure 3months after treatment. Left ventricular ejection fraction remained stable, and no significant radiation-induced inflammatory changes were noted. The initial results of this trial suggest that STAR can reduce VT episodes in patients with refractory VT without severe adverse effects. The study highlights the importance of international collaboration and standardization in pioneering new treatments. Further follow-up and additional patient data will be necessary to confirm these findings and evaluate long-term outcomes, including potential adjustments to antiarrhythmic medication regimens.
