BACKGROUND
Seizures are considered to be one of the dreaded side effects of clozapine, and due to this, the use of clozapine is avoided in patients with treatment-resistant schizophrenia. Resultantly, there is little information about the use of clozapine among patients with seizure disorder.
AIM
To assess the safety of clozapine in patients with history of seizures in their lifetime before starting clozapine and receiving clozapine for the management of psychotic disorders.
RESULTS
Out of the 958 patients, 35 (3.65 %) had a history of at least one seizure episode before starting clozapine, with a mean of 5.06 (SD: 7.23; Median: 3.00) seizures before starting clozapine. The mean duration between the last seizure and the starting of clozapine was 123.75 (SD: 124.99; Median: 84) months, with nine patients having an episode of seizure in the previous 12 months and 15 patients being seizure-free for more than ten years. About one-fourth (25.7 %; nine out of 35) of the patients had recurrence of seizure while receiving clozapine for a mean duration of about five years. When the recurrence of seizure after starting clozapine was evaluated in patients receiving antiepileptics along with clozapine, the incidence of at least one seizure was 26.67 % (4 out of 15), and among those not receiving antiepileptics, the incidence of at least one seizure was 25 % (5 out of 20). The dose of clozapine at which seizure was noted ranged from 12.5 mg to 600 mg/day with a mean of 236.25 (SD: 169.04; Median: 162.5) mg/day. In none of the patients, clozapine had to be stopped due to the continuation of seizures.
CONCLUSION
About one-fourth of the patients with history of an episode of seizure have recurrence of seizure while receiving clozapine. The demographic and clinical variables do not differ between those who develop and who do not develop seizures after starting clozapine, including concomitant use of antiepileptics.

This study investigated the effects of different types of short video addiction on social adaptation. The aim of this study was to identify the various types of short video addiction among freshmen and the correlations with career adaptability, insomnia, and depressive symptoms. We recruited 931 freshmen and used latent profile analysis to classify participants based on different characteristics of short video addiction. Based on the results of a short video addiction questionnaire, participants were found to exhibit distinct answer patterns, categorized into five types. Class 1 exhibited minimal signs of addiction. Class 2 displayed fluctuations with stronger tendencies towards withdrawal or escape. Class 3 demonstrated a moderate inability to control cravings for short videos. Class 4 showed fluctuations but with less anxiety and feelings of lost. Finally, Class 5 presented the most pronounced symptoms of short video addiction. Freshmen with varying degrees of short video addiction exhibited significant differences in career adaptability, sleep quality, and depressive symptoms. Class 1 students showed strong career adaptability and sound sleep, whereas Class 5 students had the highest depression rates. Overall, our findings suggest that the characteristics of short video addiction in first-year students also indicate poor social adaptation, which is mainly manifested as weak career adaptability, decreased sleep quality, and depressive symptoms. One way to guide first-year students to adapt to campus life is for educators to provide timely interventions for students with severe short video addiction.

Clostridioides difficile infection (CDI) poses a significant health threat due to high recurrence rates. Antimicrobial agents are commonly used to manage CDI-related diarrhoea; however, by aggravating intestinal dysbiosis, antibiotics enable C. difficile spores germination and production of toxins, the main virulence factors. Therefore, the binding of exotoxins using adsorbents represents an attractive alternative medication for the prevention and treatment of relapses. In this study, we provided evidence that the natural insoluble polysaccharides, named ABR119, extracted by plant cell cultures, effectively trap C. difficile toxins. In our experiments, ABR119 exhibited no cytotoxicity in vitro and was safely administered in vivo. In the animal model of C. difficile-associated colitis, ABR119 (50 mg/kg body weight) significantly reduced the colonic myeloperoxidase activity and severity of inflammation, preventing body weight loss. These effects were not evident when we treated animals with wheat bran polysaccharides. We did not detect bacterial killing effects of ABR119 against C. difficile nor against bacterial species of the normal gut microbiota. Moreover, ABR119 did not interfere in vitro with the antimicrobial activities of most clinically used antibiotics. In summary, ABR119 holds promise for treating and preventing C. difficile colitis by trapping the bacterial toxins, warranting further studies to assess the ABR119 potential in human infections caused by C. difficile.

BACKGROUND
Peritoneal carcinomatosis (PC) is common in patients with advanced gynecologic and gastrointestinal cancers. Frequently, patients with PC undergo palliative surgery or procedures to manage disease-related complications and side effects. However, there are limited data regarding patients' and family caregivers' decision-making processes about these procedures. Thus, we sought to describe the decision-making experiences of patients with PC who elect to pursue palliative surgical procedures and their family caregivers.
METHODS
We conducted a secondary analysis of qualitative data collected during a pilot randomized controlled trial of BOLSTER, a nurse-led telehealth intervention for patients with PC and their caregivers after an acute hospitalization and palliative procedure. Participants in both study arms described their experiences in semi-structured interviews. We re-analyzed coded qualitative data with a focus on understanding decision-making experiences surrounding palliative surgery and procedures using conventional content analysis.
RESULTS
Interviews from 32 participants, 23 patients and 9 caregivers, were analyzed. Participants reported their decision-making was complicated by illness uncertainty and a desire for clear, effective communication with surgical and medical oncology teams. Participants requested more information about the impact of palliative procedures on their daily life. Several also noted that, without improved understanding, a misalignment between patient and family caregiver goals and palliative procedures may inadvertently increase suffering.
CONCLUSION
Discussions related to patients' goals and preferences can improve the quality of treatment decision-making in patients with PC and their caregivers. Future research should test interventions to improve advanced cancer patients' illness understanding and decision-making surrounding palliative surgery and procedures.

INTRODUCTION
This study endeavors to decipher the association between Activin A and PRISm, thereby addressing the potential of Activin A as a serum biomarker for early detection and long-term clinical outcome prediction of PRISm and subsequent all-cause mortality.
METHODS
The study sample comprised middle-aged and older adults from the I-Lan Longitudinal Aging Study. Pulmonary function including forced vital capacity (FVC) and forced expiratory volume in one second (FEV) were measured. Demographic data and laboratory data (including serum Activin A levels) were also collected. Multivariate logistic regression and Cox proportional hazards models were used to identify independent predictors of PRISm and all-cause mortality, respectively.
RESULTS
Among 711 eligible participants, 34 % had PRISm. The risk of PRISm elevated with Activin A levels in group quartiles (adjusted odds ratio (aOR), Q2: 1.606 [95 % CI 0.972-2.652], p = 0.064, Q3: 2.666 [1.635-4.348], p < 0.001, Q4: 3.225 [1.965-5.293], p < 0.001). On the other hand, lower hemoglobin (aOR: 1.122, p = 0.041) and higher blood urea nitrogen (BUN) levels (aOR: 1.033, p = 0.048) were associated with increased risk of PRISm. In addition, the PRISm group had a higher all-cause mortality rate (non-PRISm 4.5% vs. PRISm 8.3 %, p = 0.038). Multivariate Cox models also identify a higher level of Activin A as a risk factor of all-cause mortality (aHR: 1.001 [1.000-1.003], p = 0.042).
CONCLUSIONS
Higher Activin A quartiles were linked to increased risk of PRISm, along with lower hemoglobin and higher BUN levels. Additonally, elevated Activin A was a significant risk factor of all-cause mortality.

INTRODUCTION AND IMPORTANCE
Arterial aneurysm is a serious condition caused by weakened arterial walls. Aorto-uni-iliac (AUI) and femorofemoral bypass are safe and effective options for managing abdominal aortic aneurysm (AAA). However, fem-fem bypass leads to longer surgical procedures and introduces additional risks such as graft infection, occlusion, wound complications, and peripheral vascular problems. This report highlights two successful cases of AAA management using the AUI approach without the need for fem-fem bypass.
CASE PRESENTATION
Two male patients, both aged about 70, presented at our medical facility complaining of abdominal pain. Investigations unveiled an approximately 10-cm AAA that was previously undetected. Subsequently, we performed an elective AUI procedure without fem-fem bypass, marking the first instance of this technique being employed in Iran successfully.
CLINICAL DISCUSSION
The placement of an AUI stent graft is generally less technically demanding compared to that of a standard bifurcated graft, especially when anatomical constraints are severe, making the latter difficult or even impossible to deploy. Beside the longer duration of stent deployment, sometimes we encounter contralateral complications to cannulate the main body. The AUI is typically used in emergency situations or when the distal aorta's internal diameter is small. The femoral-femoral bypass is advised in nearly all circumstances.
CONCLUSION
AUI stent grafts are still a viable option for treatments of AAA, especially in cases of severe aortoiliac occlusive disease or comorbidities. AUI without crossover bypass is a viable option in the patients who have stenosis of contralateral iliac artery.

INTRODUCTION AND IMPORTANCE
Meniscal root tears are defined as soft-tissue and/or osseous injuries that rip or avulse within one centimeter of the meniscal insertion to the tibial plateau. These injuries impact around 100,000 patients a year and make up 10 % to 21 % of all meniscal tears. Meniscal extrusion frequently happens when there are root rips, and the transmission of circumferential hoop loads is hampered.
CASE PRESENTATION
We present one case of a 28-year-old male who complained of pain and stiffness in his left knee since 2 years after undergoing ACL reconstruction using a hamstring autograft. His examination revealed joint line tenderness on both the medial and lateral sides of the left knee. Further investigations involving X-ray and MRI established the diagnosis of both medial and lateral meniscal root tears, which were surgically managed using the transtibial pullout technique.
DISCUSSION
The biomechanical implications of meniscal root tears, such as loss of hoop forces and increased tibiofemoral contact pressures, underscore the importance of timely diagnosis and management. The literature advocates surgical treatment for managing root tears, as leaving them without surgical intervention can lead to functional outcomes similar to those of total meniscectomy.
CONCLUSION
This case report presents both menisci posterior root tears with an intact ACL graft which is unique in that they commonly tear in conjuction with ACL. These kind of injuries necessitates prompt diagnosis and surgical intervention to protect the knee from early arthritic changes.

INTRODUCTION AND IMPORTANCE
Chondrosarcomas are the third most frequent malignant bone tumors. With pelvic bones being their most common primary location, diagnosis and treatment of these tumors is especially challenging due to the diverse clinical manifestations and involvement of critical anatomic structures. We present the case of a grade III pelvic chondrosarcoma of the left iliopubic branch managed through a multidisciplinary approach.
CASE PRESENTATION
A 26-year-old male patient presented with a 1-year history of a mass in the left iliopubic branch. The imaging findings suggested chondrosarcoma and showed extrinsic compression of pelvic structures causing right hydronephrosis, marked elongation and tortuosity of the sigmoid colon, and anterior and superior displacement of the bladder. Following multidisciplinary meeting it was decided to perform a left hemicolectomy, colostomy, and internal hemipelvectomy in the 1-2-3 left zones, with resection of the intrapelvic and intra-abdominal tumor, and preservation of the left lower extremity. The patient presented two episodes of intestinal obstruction, which resolved with medical management. Was discharged without presenting further complications.
CLINICAL DISCUSSION
Chondrosarcomas management demands a methodical approach. Appropriate surgical strategy requires individualization according to the characteristics of the lesion and the degree of involvement of surrounding structures. Complete resection of the tumor and preservation of the lower extremity function are critical achievements.
CONCLUSION
This case underscores the effective management of a challenging tumor such as pelvic chondrosarcoma. The multidisciplinary approach and collaboration of several specialties was crucial to reach an appropriate surgical strategy.

Impact of obesity after cytoreductive surgery and intraperitoneal hyperthermic chemotherapy for rare peritoneal malignancies: Paradox of obesity or poor prognostic factor?
BACKGROUND
Obesity is a public health concern with an increasing occurrence worldwide. Literature regarding impact of obesity on results after management of peritoneal carcinomatosis is poor. Our aim was to compare postoperative and oncological outcomes after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for rare peritoneal malignancies according to the body mass index.
METHODS
All the patients managed by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for rare peritoneal malignancies (including mainly pseudomyxoma peritonei and peritoneal mesothelioma), between 1995 and 2020, were retrospectively included from the French national registry of rare peritoneal tumors.
RESULTS
1450 patients were retrospectively included (63.5 % female, mean age 54 ± 13 years). Patients were divided into two groups according to their body mass index: non-obese (n = 1248, 86 %) and obese (n = 202, 14 %). Overall morbidity was significantly lower in non-obese patients in comparison with obese patients (n = 532/1248, 43 % vs n = 106/202, 53 %, p = 0.009). Medical and surgical morbidities were significantly lower in non-obese patients in comparison with obese patients (423/1258, 34 % vs n = 86/202, 43 %, p = 0.02 and n = 321/1248, 26 % vs n = 67/202, 33 %, p = 0.003, respectively). One-, 5- and 10-year overall survivals were similar between non-obese and obese patients (95 %, 82 % and 70 % vs 94 %, 76 % and 63 %; p = 0.1). One-, 5- and 10-year disease free survivals were similar between non-obese and obese patients (84 %, 67 % and 61 % vs 79 %, 62 % and 56 %, p = 0.1).
CONCLUSION
Obese patients have to be carefully managed after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for rare peritoneal malignancies. Some perioperative prophylactic treatments could be specifically implemented to reduce thromboembolic events, metabolic and wound complications.

In the current study, we aimed to investigate whether disulfiram (DSF) exerts a neuroprotective role in cerebral ischemiareperfusion (CI-RI) injury by modulating ferredoxin 1 (FDX1) to regulate copper ion (Cu) levels and inhibiting inflammatory responses. To simulate CI-RI, a transient middle cerebral artery occlusion (tMCAO) model in C57/BL6 mice was employed. Mice were administered with or without DSF before and after tMCAO. Changes in infarct volume after tMCAO were observed using TTC staining. Nissl staining and hematoxylin-eosin (he) staining were used to observe the morphological changes of nerve cells at the microscopic level. The inhibitory effect of DSF on initial inflammation was verified by TUNEL assay, apoptosis-related protein detection and iron concentration detection. FDX1 is the main regulatory protein of copper death, and the occurrence of copper death will lead to the increase of HSP70 stress and inflammatory response. Cuproptosis-related proteins and downstream inflammatory factors were detected by western blotting, immunofluorescence staining, and immunohistochemistry. The content of copper ions was detected using a specific kit, while electron microscopy was employed to examine mitochondrial changes. We found that DSF reduced the cerebral infarction volume, regulated the expression of cuproptosis-related proteins, and modulated copper content through down regulation of FDX1 expression. Moreover, DSF inhibited the HSP70/TLR-4/NLRP3 signaling pathway. Collectively, DSF could regulate Cu homeostasis by inhibiting FDX1, acting on the HSP70/TLR4/NLRP3 pathway to alleviate CI/RI. Accordingly, DSF could mitigate inflammatory responses and safeguard mitochondrial integrity, yielding novel therapeutic targets and mechanisms for the clinical management of ischemia-reperfusion injury.
