Anticoagulation therapy remains the cornerstone of treatment for cerebral venous sinus thrombosis (CVST). Endovascular therapy may be considered in selected patients with clinical deterioration despite optimal medical treatment. However, conventional mechanical thrombectomy using aspiration and/or stent-retrievers might be inadequate in extensive CVST because of large and organized thrombi and non-availability of venous thrombectomy devices. We present a technical modification using an angioplasty non-compliant (NC) balloon as an adjunct to suction thrombectomy for venous sinus mechanical thrombectomy in a case of extensive CVST. Conventional methods of thrombectomy failed to recanalize the sinuses; hence, an angioplasty NC balloon was used to decimate the clot with simultaneous suction thrombectomy to achieve near-complete recanalization of the affected sinuses with good clinical outcome. We name this the “pipeline-pigging” technique. The pipeline-pigging method of using a normal angioplasty NC balloon for venous sinus mechanical thrombectomy may serve as an effective and economical technical adjunct for extensive CVST refractory to conventional methods. This approach facilitates thrombus fragmentation, aspiration and improved delivery of thrombolytics and may expand the endovascular armamentarium for extensive CVST.

Objective: Parkinson’s disease (PD) affects approximately 2% of individuals over the age of 60. With more than two billion Muslims observing Ramadan, individuals with PD encounter specific challenges, such as deteriorating motor skills, sleep disturbances, and an increased risk of falls during fasting. Methods: Our study focused on 75 patients with idiopathic PD divided into two groups: the Ramadan Regime group, which consisted of 50 patients whose medication was adjusted to twice daily at Suhoor and Iftar, and the Nontreatment group, which included 25 patients who abstained from medication for religious reasons. Both groups were instructed to wear a Parkinson’s KinetiGraph (PKG) wrist device. Results: The study findings revealed that motor function worsened in the Nontreatment group (p<0.001) but improved in the Ramadan Regime group (p=0.007). Daytime sleepiness also significantly increased in the Nontreatment group (p<0.001). Conclusion Overall, the findings suggest that the Ramadan regime significantly enhances patient health and quality of life.

Background/Aims: Quick sequential organ failure assessment (qSOFA) is believed to identify patients at risk of poor outcomes in those with suspected infection. We aimed to evaluate the ability of modified qSOFA (m-qSOFA) to identify high-risk patients among those with acutely deteriorated chronic liver disease (CLD), especially those with acute-onchronic liver failure (ACLF). Methods: We used data from both the Korean Acute-on-Chronic Liver Failure (KACLiF) and the Asian Pacific Association for the Study of the Liver ACLF Research Consortium (AARC) cohorts. qSOFA was modified by replacing the Glasgow Coma Scale with hepatic encephalopathy, and an m-qSOFA ≥2 was considered high. Results: Patients with high m-qSOFA had a significantly lower 1-month transplant-free survival (TFS) in both cohorts and higher organ failure development in KACLiF than those with low m-qSOFA (Ps<0.05). Subgroup analysis by ACLF showed that patients with high m-qSOFA had lower TFS than those with low m-qSOFA. m-qSOFA was an independent prognostic factor (hazard ratios, HR=2.604, 95% confidence interval, CI 1.353–5.013, P=0.004 in KACLiF and HR=1.904, 95% CI 1.484– 2.442, P<0.001 in AARC). The patients with low m-qSOFA at baseline but high m-qSOFA on day 7 had a significantly lower 1-month TFS than those with high m-qSOFA at baseline but low m-qSOFA on day 7 (52.6% vs. 89.4%, P<0.001 in KACLiF and 26.9% vs. 61.5%, P<0.001 in AARC). Conclusions Baseline and dynamic changes in m-qSOFA may identify patients with a high risk of developing organ failure and short-term mortality among CLD patients with acute deterioration.

Background: Existing literature lacks high-quality evidence regarding the ideal intraoperative positive end-expiratory pressure (PEEP) to minimize postoperative pulmonary complications (PPCs). We hypothesized that applying individualized PEEP derived from electrical impedance tomography would reduce the severity of postoperative lung aeration loss, deterioration in oxygenation, and PPC incidence. Methods: A pilot feasibility study was conducted on 36 patients who underwent open abdominal oncologic surgery. The patients were randomized to receive individualized PEEP or conventional PEEP at 4 cmH2O. The primary outcome was the impact of individualized PEEP on changes in the modified lung ultrasound score (MLUS) derived from preoperative and postoperative lung ultrasonography. A higher MLUS indicated greater lung aeration loss. The secondary outcomes were the PaO2/FiO2 ratio and PPC incidence. Results: A significant increase in the postoperative MLUS (12.0 ± 3.6 vs 7.9 ± 2.1, P < 0.001) and a significant difference between the postoperative and preoperative MLUS values (7.0 ± 3.3 vs 3.0 ± 1.6, P < 0.001) were found in the conventional PEEP group, indicating increased lung aeration loss. In the conventional PEEP group, the intraoperative PaO2/FiO2 ratios were significantly lower but not the postoperative ratios. The PPC incidence was not significantly different between the groups. Post-hoc analysis showed the increase in lung aeration loss and deterioration of intraoperative oxygenation correlated with the deviation from the individualized PEEP. Conclusions Individualized PEEP appears to protect against lung aeration loss and intraoperative oxygenation deterioration. The advantage was greater in patients whose individualized PEEP deviated more from the conventional PEEP.

As of August 16,2021,there have been 207,173,086 confirmed cases and 4,361,996 deaths due to the coronavirus disease(COVID-19),and the pandemic remains a global challenge.To date,no effective and approved drugs are available for the treatment of COVID-19.Angiotensin-converting enzyme 2(ACE2)plays a crucial role in the invasion into host cells by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the etiological agent of COVID-19.Notably,ACE2 density is influenced by medical con-ditions,such as hypertension,or by drugs,including angiotensin-converting enzyme inhibitors(ACEIs)and angiotensin receptor blockers(ARBs),which can change the fate of SARS-CoV-2 infectivity.ACE2 is a target for these drugs and can be manipulated to limit the viral entry and replication within the cells.Different strategies aimed at blocking ACE2 with small molecules,peptides,and antibodies,or by neutralizing the virus through its competitive binding with human recombinant soluble ACE2(hrsACE2)are currently under investigation.In this article,we review the current state of knowledge that em-phasizes the need to find effective therapeutic agents against COVID-19 by exploiting ACE2 as a potential target.The increased soluble ACE2 levels and the application of hrsACE2 in patients with COVID-19 can be implemented to control the disease.It has not yet been established whether hypertension and other comorbidities,independent of age,have a direct role in COVID-19.Therefore,the use of renin-angiotensin system inhibitors,ACEls and ARBs,should not be discontinued during COVID-19 treatment.

Herein, the synthesis of nanocomposites based on polymers, along with their classification as conductive hydrogels and bioscaffolds, is comprehensively discussed. Furthermore, their implementation in numerous tissue engineering and regenerative medicine applications is also described. The limitations of tissue engineering are also discussed here. The present review highlights and summarizes the latest progress in the tissue engineering domain directed at functionalized nanomaterials.

Objective: To investigate the biochemical capacity, and in vitro inhibitory effects of hairy roots from two cultivars of Ficus carica L. (Sabz and Siah) on Leishmania major promastigotes and amastigotes. Methods: In the hairy roots, the activity of antioxidant enzymes compared to normal leaves and roots, and the presence of some phenolic compounds in comparison with fruits were investigated. The IC 50 values of hairy roots in promastigotes was determined by tetrazolium-dye 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide and trypan blue assays. By calculating the infectivity index of peripheral blood mononuclear cells (PBMCs), the leishmanicidal activity (IC 50 values) of hairy roots for amastigotes was estimated. The effects of hairy roots (IC 50 values) treatment on the levels of IFN-γ and iNOS expression, intracellular reactive oxygen species, and iNOS protein expression in infected-PBMCs were determined. Results: Based on antioxidant enzyme assays and high performance liquid chromatography analysis, hairy roots exhibited high antioxidant capacity and contained high levels of phenolic compounds. According to the results of tetrazolium-dye 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide and trypan blue assays, the hairy root extracts of both cultivars showed considerable dose-dependent inhibitory effects against Leishmania major promastigotes. Depending on the concentration and exposure time, treatment of infected-PBMCs with hairy root extracts caused the generation of a significant reactive oxygen species, up-regulation of IFN-γ and iNOS genes expression, and high value of iNOS protein compared to controls. Conclusions: The findings of this study suggest that the hairy roots of Ficus carica can be considered as a promising natural source of antileishmanial agents.

Background/Aims: Liver cirrhosis is an important cause of morbidity and mortality globally. Every episode of decompensation and hospitalization reduces survival. We studied the clinical profile and long-term outcomes comparing alcohol-related cirrhosis (ALC) and non-ALC.
Methods: Cirrhosis patients at index hospitalisation (from January 2010 to June 2017), with ≥1 year follow-up were included.
Results: Five thousand and one hundred thirty-eight cirrhosis patients (age, 49.8±14.6 years; male, 79.5%; alcohol, 39.5%; Child-A:B:C, 11.7%:41.6%:46.8%) from their index hospitalization were analysed. The median time from diagnosis of cirrhosis to index hospitalization was 2 years (0.2–10). One thousand and seven hundred seven patients (33.2%) died within a year; 1,248 (24.3%) during index hospitalization. 59.5% (2,316/3,890) of the survivors, required at least one readmission, with additional mortality of 19.8% (459/2,316). ALC compared to non-ALC were more often (P<0.001) male (97.7% vs. 67.7%), younger (40–50 group, 36.2% vs. 20.2%; P<0.001) with higher liver related complications at baseline, (P<0.001 for each), sepsis: 20.3% vs. 14.9%; ascites: 82.2% vs. 65.9%; spontaneous bacterial peritonitis: 21.8% vs. 15.7%; hepatic encephalopathy: 41.0% vs. 25.0%; acute variceal bleeding: 32.0% vs. 23.7%; and acute kidney injury 30.5% vs. 19.6%. ALC patients had higher Child-Pugh (10.6±2.0 vs. 9.0±2.3), model for end-stage liver-disease scores (21.49±8.47 vs. 16.85±7.79), and higher mortality (42.3% vs. 27.3%, P<0.001) compared to non-ALC.
Conclusions One-third of cirrhosis patients die in index hospitalization. 60% of the survivors require at least one rehospitalization within a year. ALC patients present with higher morbidity and mortality and at a younger age.

Objective: Laparoscopy has now become a state-of-the-art technique for many diagnostic and therapeutic procedures with known advantages over laparotomy. There is scarce literature from India regarding minilaparoscopy, as per our literature review. Therefore, we performed this study with a 2.9-mm laparoscope to determine its feasibility and efficacy for diagnostic purposes and level II surgeries with the aim of reducing postoperative pain and better cosmesis. Methods: This was a prospective study conducted from June 2019 to March 2020. Diagnostic modern minilaparoscopy with a 2.9-mm telescope was performed under general anesthesia by a single surgeon. Operative intervention was performed depending on the intraoperative findings. Results: The mean age was 29.3 years. The most common indication for laparoscopy was infertility (98%). Only diagnostic laparoscopy was performed in 76% of patients, while 24% underwent operative laparoscopy. The various operative procedures performed were cystectomy, salpingectomy, ovarian drilling, and adhesiolysis. The mean visual analog scale scores at 1 hour and 2 hours postoperatively and discharge were 1.57±0.59, 1.41±0.51, and 1.29±0.47, respectively. Mild pain was present in 70 (72.2%) patients at the time of discharge, and only one patient had severe pain. Five or more analgesic tablets were required in only 16.5% of patients in the postoperative period. There was no wound infection or port-site hernia at follow-up. Conclusion Modern minilaparoscopy with a 2.9-mm laparoscope is a feasible and safe option for diagnostic laparoscopy and level II gynecological procedures with minimal postoperative morbidity, such as pain and wound infection, and provides good cosmetic outcomes.
