Abstract
INTRODUCTION Cerebral venous thrombosis is an uncommon cause of cerebrovascular disease, which has been increasing worldwide. In Colombia, there are not enough recent studies that allow us to determine epidemiological characteristics of the disease in our population to identify more frequent risk factors and complications according to our living conditions. OBJETIVE To describe clinical, demographic, and radiographic characteristics, and risk factors in a cohort of patients with cerebral venous thrombosis attended at two hospitals in Colombia. MATERIALS AND METHODS Retrospective descriptive study with patients treated in the hospitalization neurology service of two hospitals in Bogotá, Colombia from December 2018 to December 2020. RESULTS Thirty-three patients were included. There was a higher incidence of cerebral venous thrombosis in women of childbearing age in the puerperium (n=7; 33.3%) and associated with autoimmune diseases (n=10; 30.3%). The most common initial symptom was headache (n=31; 93.9 %), followed by neurological focal signs (n=9; 27.2%) and seizures (n=8; 24.2%). Fifty-one percent (n=17) of the patients had a normal physical examination. Cerebral venous infarction occurred in 21.1 % (n=7), subarachnoid hemorrhage in 12.1 % (n=4), and intraparenchymal hematoma in 9 % (n=3) of all the patients. Sixty-point six percent (n=20) of the patients had a total independent Barthel functional scale. None of those died. CONCLUSIONS We found similar sociodemographic, clinical, and radiography characteristics to those reported in the world literature. Regarding the differences, deep cerebral venous circulation was higher than that described in previous studies but without complications increase or mortality.

Abstract
OBJECTIVES As the second most common subtype of Epithelial ovarian cancers (EOCs), ovarian clear cell carcinoma (OCCC) is associated with a high rate of cancer-associated thrombosis. Previous studies revealed the wide range prevalence (6-42%) of venous thromboembolism (VTE) among OCCC patients. This study aimed to determine the prevalence of VTE among OCCC patients as well as factors affecting it. METHODS PubMed, Scopus, Embase, and Cochrane Library databases were searched up to December 12th, 2022. Studies reporting venous thromboembolic events in women with clear cell carcinoma of the ovary were included. Demographic data, clinical, and paraclinical features of the patients were independently extracted by two reviewers. RESULTS Out of the 2254 records, 43 studies were processed for final review. The qualified studies involved 573 VTE cases among 2965 patients with OCCC. The pooled prevalence of VTE among OCCC patients was 21.32% (95%CI=(17.38-25.87)). Most VTE events were reported in Japanese women (26.15%), followed by Americans (24.41%) and UK (21.57%), and Chinese (13.61%) women. VTE was more common in patients with advanced stages (37.79%) compared to those with early stages of the disease (16.54%). CONCLUSIONS Ovarian clear cell carcinoma is associated with a high rate of cancer-associated thrombosis. VTE events in OCCC patients were higher in advanced stages and Japanese women.

Abstract
Splanchnic vein thrombosis (SVT) is an unusual-site venous thromboembolism that includes portal, mesenteric, and splenic vein thrombosis as well as the Budd-Chiari syndrome. SVT is a relatively rare disease (portal vein thrombosis and Budd-Chiari syndrome are, respectively, the most and the least common presentations); roughly one‑third of the cases are detected incidentally, and liver cirrhosis and solid cancer represent the main risk factors. Once SVT is diagnosed, careful patient evaluation should be performed to assess the stage, grade, and extension of the thrombosis, as well as the risks and benefits of the anticoagulation regimen. Anticoagulant therapy is effective in SVT treatment and is associated with high rates of vein recanalization, low rates of thrombosis progression or recurrence, and an acceptable rate of bleeding complications. Most available data come from observational studies in patients with liver cirrhosis-related SVT receiving low‑molecular‑weight heparin or vitamin K antagonists. Data on the use of direct oral anticoagulants are increasing and promising. In selected patients and in specialized centers, interventional procedures may be considered in adjunction to anticoagulation in the cases of mesenteric or extensive SVT, intestinal ischemia, or in the patients whose condition deteriorates despite adequate anticoagulant therapy. In this narrative review, we summarize the available data regarding anticoagulation in patients with SVT, identify specific subgroups of patients who may achieve the greatest benefits from anticoagulant therapy, and provide practical advice for clinicians caring for these patients.

Abstract
BACKGROUND Arm restriction after cardiac implantable electronic device (CIED) placement is common practice despite minimal supporting evidence. Patients receive a range of restriction recommendations of variable durations with the goal of reducing complications such as wound dehiscence, infection, lead dislodgement, or hematoma formation. These movement limitations can lead to emotional stress and anxiety, complications such as frozen shoulder, and upper extremity venous thrombosis due to immobilization. There are no published clinical trials assessing the benefits and risks of arm restrictions post-CIED implant. OBJECTIVES The randomized trial of lenient vs strict arm and activity instruction post-CIED surgery (LENIENT trial; NCT04915261) is a single center nonblinded randomized prospective study designed to evaluate lenient compared to restrictive post-CIED care instructions. We hypothesize that there will be no significant difference in complications between the arms. METHODS/DESIGN All patients receiving a de novo CIED or those with upgrades and revisions requiring a new lead implant will be enrolled. Subjects are enrolled in a nonblinded randomized prospective trial with 6 randomly assigned 8-month periods, during which either a lenient or restrictive postoperative activity instructions will be given to all patients. Postoperative instructions are given at the time of discharge and further reinforced by recurrent interactive voice recognition (IVR) phone calls, text messages and emails. The requirement for individual consent has been waived. The primary end point is a composite of (1) lead dislodgement, (2) frozen shoulder, (3) upper extremity venous thrombosis, (4) clinically significant hematoma, and (5) infection occurring within 52 weeks of index surgery. The study is a noninferiority trial with a sample size of 1,250 per group. DISCUSSION This is the first large randomized clinical trial designed to establish an evidence-based postoperative standard of care for patients undergoing CIED implantation. This will improve the quality of care provided to patients and help guide implanting physicians providing postoperative care instructions. TRIAL REGISTRATION ClinicalTrials.gov NCT04915261.

Abstract
BACKGROUND Open reduction internal fixation (ORIF) of distal radius and ulnar fractures (DRUFs) is one of the most common fracture surgeries for hand surgeons. Few studies have evaluated how frailty contributes to outcomes in geriatric hand surgery patients. This study hypothesizes that geriatric patients scoring higher on the modified Frailty Index 5 (mFI-5) are at greater risk of postoperative complications following DRUF fixation. METHODS The American College of Surgeons National Surgical Quality Improvement Project database was reviewed for ORIF for DRUFs from 2005 to 2017. Statistically significant differences for demographics, comorbidities, mFI-5, and postoperative complications between geriatric and nongeriatric patients were evaluated with multivariate logistic regression analysis. RESULTS A total of 17,097 ORIF for DRUFs were collected by the National Surgical Quality Improvement Project 2005-2017, with 5654 patients older than 64 years (33.2%). Average age for geriatric patients undergoing ORIF for DRUFs was 73.7 years. Within geriatric patients, an mFI-5 score >2 confers 1.6-times increased risk of returning to the operating room following ORIF for DRUF (adjusted odds ratio, 1.6; P = 0.02), whereas an increase in mFI-5 score >2 confers a 3.2-times increased risk of deep vein thrombosis among geriatrics (adjusted odds ratio, 3.2 P < 048). CONCLUSION Frailty among geriatric patients confers increased risk of deep vein thrombosis postoperatively. Geriatric patients with higher frailty scores carry a significantly increased risk of returning to the operating room within 30 days. Hand surgeons can use the mFI-5 to screen geriatric patients with DRUF patients to guide perioperative decision-making.

Abstract
INTRODUCTION Vascular complications are severe complications of pediatric kidney transplantation (KT). We aimed to investigate whether a complex bench surgery (BS) affects the outcomes. METHODS All pediatric KT performed at the University Hospital of Padua from 2015 to 2019 were analyzed, comparing those in which a standard BS was possible to those that necessitated a complex BS. The rates of vascular complications, patients' outcome, and graft survival were compared in the two groups. RESULTS Eighty KTs were performed in 78 patients with a median age of 11 years (interquartile range [IQR] 4.3-14) and a median body weight of 24 kg (IQR 13-37). Thirty-nine donor kidneys (49%) needed a complex BS due to anomalies of renal veins in 12 (31%) and renal arteries in 16 (41%). The remaining 11 grafts (28%) underwent an elongation of the vein. There was no difference in the rate of primary graft non function (p = 0.97), delayed graft function (p = 0.72), and overall survival (p = 0.27). The rates of vascular complications, bleedings, and venous graft thrombosis were similar (p = 0.51, p = 0.59, p = 0.78, respectively). No arterial thrombosis or stenosis was reported. CONCLUSION Complex BS did not compromise survival of the graft and did not put the allograft at risk of vascular complications, such as bleedings or thrombosis.

Abstract
Venous thromboembolism (VTE), which entails the formation of a thrombus (blood clot) in a vein, has a significant disease burden worldwide. While VTE has traditionally been considered to predominantly affect Caucasian populations, recent studies have indicated a gradual shift in the disease burden towards Asian populations, with added significance of it being a key driver of post-operative mortality. It is imperative to develop a sound understanding of the various factors that affect VTE in stratified local populations. However, there is a glaring paucity of quality data on VTE and its ramifications among Indians - both in terms of quality of life and cost of healthcare. This review aims to throw light on the disease burden, epidemiology, risk factors, environmental factors, food and nutrition that plays a key role in VTE. We also explored the association of VTE with coronavirus disease 2019 to grasp the interplay between the two most significant public health crises of our time. It is vital to place a special emphasis on future research on VTE in India to plug the gaps, which exist in our current knowledge of the disease, particularly with respect to Indian population.

Abstract
Background & aimsLittle is known about molecular biomarkers that predict the response and prognosis in unresectable hepatocellular carcinoma (HCC) treated with programmed death (PD)-1 inhibitors.MethodsA total of 62 HCC patients who underwent next-generation sequencing were retrospectively included in our department for this study. Patients with unresectable disease were subjected to systemic therapy. PD-1 inhibitors intervention (PD-1Ab) group and nonPD-1Ab group included 20 and 13 patients, respectively. Primary resistance was defined as initial on-treatment progression or progression with an initial stable disease of less than 6 months.ResultsChromosome 11q13 amplification (Amp11q13) was the most common copy number variation in our cohort. Fifteen (24.2%) patients harbored Amp11q13 in our dataset. Patients with Amp11q13 showed higher level of Des-γ-carboxy-prothrombin (DCP), tumor number and were more prone to be combined with portal vein tumor thrombosis (PVTT). In the PD-1Ab group, the proportion of progressive disease (PD) in patients with Amp11q13 was significantly higher than that in patients with nonAmp11q13 (100% vs 33.3%, P=0.03). In the nonPD-1Ab group, the proportion of PD in patients with Amp11q13 and nonAmp11q13 had no significant difference (0% vs 11.1%, P>0.99). In the PD-1Ab group, the median progression-free survival (PFS) was 1.5 months in Amp11q13 patients vs 16.2 months in non-Amp11q13 patients (HR, 0.05; 95% CI 0.01-0.45; P = 0.0003). No significant difference was observed in the nonPD-1Ab group. Notably, we found that hyperprogressive disease (HPD) might be associated with Amp11q13. The increased density of Foxp3+ Treg cells in HCC patients with Amp11q13 might be one of potential mechanisms.ConclusionHCC patients with Amp11q13 are less likely to benefit from PD-1 blockade therapies. These findings may help guide the use of immunotherapy for HCC in routine clinical practice.

Abstract
BACKGROUND Porto-sinusoidal vascular disease (PSVD) is a novel nomenclature to describe non-cirrhotic portal hypertension and characteristic histology without portal vein thrombosis (PVT). It is a more inclusive definition than the previously well-recognized entity idiopathic non-cirrhotic portal hypertension. There is a paucity of data on PSVD patients. METHODS A total of 33 patients diagnosed with PSVD and portal hypertension (PH) between 2005 and 2021 were included. Data were retrieved from electronic medical record system and analyzed. RESULTS Of the 33 patients, 6 (18%) occurred in post-transplant allograft liver. After a median follow-up of 96 months (interquartile range, IQR [52, 139]), 14 deaths occurred (42%), 4 directly related to decompensated liver disease. The Kaplan-Meier survival estimates at 1, 5, and 10 years were 94%, 87% and 58%. PVT occurred in 10 patients (30%). The Nelson-Aalen cumulative risk estimate for PVT at 1, 5 and 10 years were 16%, 25% and 48%. The median model for end-stage liver disease and Child-Pugh score at initial presentation were 8 (IQR [7-12]) and 5 [5-6], and increased to 13 [8, 18] and 7 [5, 8], respectively, at the end of follow-up. Of the 11 patients who presented with splenomegaly and no specific sign of PH, 7 (64%) developed varices and 3 (27%) ascites at a median follow-up of 100 months. CONCLUSIONS PSVD with PH is not a benign entity. Mortality, PVT and hepatic decompensation are common. Patients with PSVD must be closely monitored, including those who only have non-specific clinical signs (e.g., splenomegaly) of PH.

Abstract
BACKGROUND Venous thromboembolism (VTE) represents a considerable burden on cancer patients' survival and quality of life, but this burden varies based on the patient's baseline characteristics and cancer-related factors. Although solid evidence on the predictors and effect of VTE in cancer patients exists. AIM To evaluate VTE rate, morbidity, and mortality to develop parameters that could predict VTEs and their associated mortality in patients with multiple primary malignancies (MPMs). METHOD AND RESULTS This was a retrospective cohort study that took place at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia. Two hundred and forty-two patients with at least two biopsy-proven malignancies and had at least 3 months of follow-up after MPMs diagnosis were included. VTE was diagnosed in 14.5% of the cases, two-thirds of which were deep vein thrombosis. VTE was significantly associated with a higher mortality and worse survival. Predictors of VTE after MPMs diagnosis were a high ECOG performance status at MPMs diagnosis, a metastatic first primary malignancy, and ICU admission after MPMs diagnosis. Having a GI or hematological malignancy as the second primary malignancy, a high D-dimer at ICU admission, and palliative care referral were significantly associated with a higher mortality in patients who had VTE. CONCLUSION VTE was diagnosed in 14.5% of patients with MPMs and it significantly compromises their survival. We believe that these results might be of particular benefit since the phenomenon of MPMs is becoming more frequently encountered.

Abstract
BACKGROUND Totally implantable venous access devices (TIVADs) are widely used to gain intermittent central venous access, such as in patients who need long-term chemotherapy, total parenteral nutrition, and long-term antibiotic treatment. At present, there are many complications associated with the use of these devices. Complete extravascular migration of TIVADs via the internal jugular vein is a very rare and potentially serious condition, especially in children. CASE PRESENTATION A 1-year-old girl needed palliative chemotherapy because of hepatoblastoma complicated by inferior vena cava thrombosis. A TIVAD was implanted through the right internal jugular vein with a routine heparin flushing tube. On the second day after the operation, a pale bloody liquid was drawn out from the device and the chest X-ray was checked to confirm that the position of the catheter was normal. On the third day after the operation, however, the patient's right respiratory sound was weakened on physical examination and auscultation. Fluoroscopy showed that the tip of the catheter was located in the right thoracic cavity, and there was a large amount of effusion in the right thoracic cavity. The pleural effusion was removed, the TIVAD was replaced again, and the child was discharged 2 days later. CONCLUSIONS Following TIVAD implantation, if abnormalities are found, in addition to chest X-ray, saline flush and echocardiography should be performed to determine the position of the catheter and rule out extravascular migration of the catheter to avoid irreparable consequences.

Abstract
BACKGROUND Pancreatic neuroendocrine neoplasms (PNENs) are a rare group of neoplasms originating from the islets of the Langerhans. Portal vein tumor thrombosis has been reported in 33% of patients with PNENs. While the histopathological diagnosis of PNENs is usually based on percutaneous biopsy or endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), these approaches may be impeded by gastric varices, poor access windows, or anatomically contiguous critical structures. Obtaining a pathological diagnosis using a gastroscope biopsy forceps via percutaneous transhepatic intravascular pathway is an innovative method that has rarely been reported.
CASE SUMMARY A 72-year-old man was referred to our hospital for abdominal pain and melena. Abdominal contrast-enhanced magnetic resonance imaging revealed a well-enhanced tumor (size: 2.4 cm × 1.2 cm × 1.2 cm) in the pancreatic tail with portal vein invasion. Traditional pathological diagnosis via EUS-FNA was not possible because of diffuse gastric varices. We performed a percutaneous transportal biopsy of the portal vein tumor thrombus using a gastroscope biopsy forceps. Histopathologic examination revealed a pancreatic neuroendocrine neoplasm (G2) with somatostatin receptors 2 (+), allowing systemic treatment.
CONCLUSION Intravascular biopsy using gastroscope biopsy forceps appears to be a safe and effective method for obtaining a histopathological diagnosis. Although well-designed clinic trials are required to obtain more definitive evidence, this procedure may help improve the diagnosis of portal vein thrombosis and related diseases.

Abstract
Vascular liver diseases are an heterogenous group of diseases that collectively represent an important health issue in the field of liver diseases. This narrative review was elaborated by the Special Interest Group (SIG) "Gender in Hepatology" of the Italian Association for the Study of the Liver (AISF). We aimed to review the current knowledge regarding the potential role of biological sex in patients with vascular liver diseases such as splanchnic vein thrombosis, hepatic vein thrombosis, porto-sinusoidal vascular disorder, and hereditary hemorrhagic telangiectasia. As vascular liver diseases commonly affect young individuals, including women in childbearing age, we also included a specific section on the management of pregnancy in these challenging patients.

Abstract
BACKGROUND Cisplatinum-based chemotherapy is associated with an increased risk of venous thromboembolism (VTE). We hypothesized that primary thromboprophylaxis in patients with testicular germ cell tumors (GCT) undergoing cisplatinum-based chemotherapy can reduce the risk of VTE. PATIENTS AND METHODS In this single-center retrospective cohort study, we investigated the increased use of primary thromboprophylaxis between January 2000 and December 2021 at our institution and its effect on the risk of VTE. Patients with GCT undergoing adjuvant or curative cisplatinum-based chemotherapy were included. RESULTS Three hundred forty-six patients with GCT initiating a cisplatinum-based therapy were included in the study, of whom 122 (35%) were treated in the adjuvant and 224 (65%) in the curative setting, respectively. VTE events occurred in 49 (14.2%) patients. In univariable competing risk analysis, a higher clinical tumor stage and large retroperitoneal lymphadenopathy (RPLND >5 cm) were the strongest predictors of an elevated VTE risk (SHR for stage IIC - IIIC: 2.6 (95%CI: 5.0-24.7, P < .001), SHR for RPLN: 2.36 (95%CI: 1.27-4.4, P < .007)). The proportion of patients receiving primary thromboprophylaxis strongly increased over time and reached 100% in CS IIC-III patients from 2019 onwards. After adjusting for tumor stage, primary thromboprophylaxis was associated with a 52% relatively lower risk of VTE (SHR = 0.48, 95% CI: 0.24-0.97; P = .032). CONCLUSION In this retrospective cohort study, we showed that TGCT patients undergoing cisplatinum-based chemotherapy have a lower VTE risk when receiving primary thromboprophylaxis. For the duration of chemotherapy, primary thromboprophylaxis should be considered on a risk-benefit ratio.

Abstract
A man in his 70s, with a history of a glomus jugulare paraganglioma diagnosed 18 years ago, presented with an unprovoked deep vein thrombosis (DVT). The paraganglioma had been treated by radiotherapy, and yearly scans had not shown any progression since treatment. A sclerotic focus in L4 vertebral body was reported on a CT scan of the neck and trunk which was done to exclude a neoplastic process being the precipitating factor for the DVT. Nuclear imaging showed multiple areas of bony uptake, suggestive of metastases. A bone biopsy of the left femur resulted positive for metastatic paraganglioma. A monthly intramuscular injection of octreotide 30 mg was prescribed.

Abstract
A series of pyrrolo[3,2-d]pyrimidineone compounds have been designed and synthesized as novel FXa inhibitors. Bioassay of the tested compounds showed moderate to excellent anticoagulant potency in vitro. Further FXa inhibitory and bioactivity evaluation in rats, the FeCl3-induced venous thrombosis model, showed that the compound 17a has good FXa inhibitory activity (IC50 = 1.57 nM) and in vivo antithrombotic potency. The anticoagulant effects of compound 17a were dose dependent whether in vitro or in vivo. The results further confirmed our hypothesis that the large conjugated structure is an ideal skeleton binding FXa.

Abstract
Acute venous thromboembolism (VTE) is a common worldwide disease admitted to emergency departments (ED), usually presenting as pulmonary embolism or lower limb deep vein thrombosis (DVT). Due to the lack of typical clinical and biomarker diagnostic features of unprovoked VTE, early identification is challenging and has direct consequences on correct treatment delay. Longitudinal, prospective, observational study. Patients admitted to ED with a suspicion of unprovoked acute VTE between October 2020 and January 2021 were included. Clinical and laboratorial variables were compared between VTE positive and negative diagnoses. Red cell distribution width (RDW) cut point was determinate through a receiver operating characteristic analysis. RDW accuracy, sensitivity, and specificity were calculated. Fifty-eight patients were analyzed. And 82.8% of suspected patients with VTE were diagnosed with an acute thrombotic event confirmed by imaging examination. In patients with VTE, RDW at admission in ED was higher than with other diagnosis, respectively, 14.3% (13.2-15.1) and 13.5% (13.0-13.8). Platelet count was the only additional characteristic that revealed difference between the 2 groups (264×109/L for VTE and 209×109/L for non-VTE). Logistic regression models showed good discriminatory values for RDW≥14%, with an area under the curve (AUC) = 0.685 (95% confidence interval, 0.535-0.834). These findings were more pronounced in isolated DVT, with a sensitivity of 76.9%, specificity 100%, and accuracy 85.7%. Our study demonstrated a significant association between an early high RDW and the diagnosis of acute unprovoked DVT. RDW ≥ 14% has an independent predictor of unprovoked VTE in adult patients.

Abstract
Philadelphia chromosome-negative myeloproliferative neoplasms (Ph- MPN) in children, adolescents, and young adults (AYA) attract attention from hematologists because they are identified more than before due to the recognition and advancement of diagnostic capacity for Ph- MPN. The clinical features of Ph- MPN diagnosed in children and AYA are found to be different from those of Ph- MPN that occur in patients in their 60s, peak age of onset. Ph- MPN diagnosed in children and AYA has more triple-negative cases with no identifiable driver genes and a larger proportion of venous thrombosis in thrombotic events. In terms of treatment, there are still problems to be resolved that are unique to younger patients, such as choosing cytoreductive agents for long-term use and the development of optimal prevention of thrombotic or bleeding events during pregnancy and childbirth. In this paper, we will discuss the clinical research supporting these claims and offer some practical advice for treating young children with Ph- MPN daily.

Abstract
We present the case of a patient with venous thromboembolic disease and contraindication to anticoagulation, where the incidental finding of a duplication of the inferior vena cava was made. This observation determined the need to implant two embolic protection filters. Although this vascular anomaly is rarely present, it is important to keep this possibility in mind to ensure that proper protection is provided when inferior vena cava filters are implanted.

Abstract
PURPOSE OF REVIEW A variety of neurological complications have been reported following the widespread use of the COVID-19 vaccines which may lead to vaccine hesitancy and serve as a major barrier to the public health aim of achieving protective herd immunity by vaccination. In this article, we review the available evidence regarding these neurological adverse events reported, to provide clarity regarding the same so that unfounded fears maybe put to rest. RECENT FINDINGS There is a greater than expected occurrence of severe neurological adverse events such as cortical sinus venous thrombosis, Bell's palsy, transverse myelitis, and Guillain-Barré syndromes along with other common effects such as headaches following different kinds of COVID-19 vaccination. Precipitation of new onset demyelinating brain lesions with or without detection of specific antibodies and worsening of pre-existing neurological disorders (like epilepsy, multiple sclerosis) are also a matter of great concern though no conclusive evidence implicating the vaccines is available as of now. The COVID-19 pandemic is far from being over. Till such time that a truly effective anti-viral drug is discovered, or an appropriate therapeutic strategy is developed, COVID-appropriate behavior and highly effective mass vaccination remain the only weapons in our armamentarium to fight this deadly disease. As often occurs with most therapeutic means for the treatment and prevention of any disease, vaccination against COVID-19 has its hazards. These range from the most trivial ones like fever, local pain and myalgias to several potentially serious cardiac and neurological complications. The latter group includes conditions like cerebral venous thrombosis (curiously often with thrombocytopenia), transverse myelitis and acute inflammatory demyelinating polyneuropathy amongst others. Fortunately, the number of reported patients with any of these serious complications is far too low for the total number of people vaccinated. Hence, the current evidence suggests that the benefits of vaccination far outweigh the risk of these events in majority of the patients. As of now, available evidence also does not recommend withholding vaccination in patients with pre-existing neurological disorders like epilepsy and MS, though adenoviral vaccines should be avoided in those with history of thrombotic events.

Abstract
Background and Objectives: Previous studies regarding tranexamic acid (TXA) in total knee arthroplasty (TKA) investigated only symptomatic deep vein thrombosis (DVT), or did not include high risk patients. The incidence of DVT including both symptomatic and asymptomatic complications after applying topical TXA has not been evaluated using ultrasonography. Materials and Methods: The medical records of 510 patients who underwent primary unilateral TKA between July 2014 and December 2017 were retrospectively reviewed. Because TXA was routinely applied through the topical route, those who had a history of venous thromboembolism, myocardial infarction, or cerebral vascular occlusive disease, were not excluded. Regardless of symptom manifestation, DVT was examined at 1 week postoperatively for all patients using ultrasonography, and the postoperative transfusion rate was investigated. The study population was divided according to the use of topical TXA. After the two groups were matched based on the propensity scores, the incidence of DVT and the transfusion rate were compared between the groups. Results: Of the 510 patients, comprising 298 patients in the TXA group and 212 patients in the control group, DVT was noted in 22 (4.3%) patients. Two patients had DVT proximal to the popliteal vein. After propensity score matching (PSM), 168 patients were allocated to each group. In all, 11 patients in the TXA group and seven patients in the control group were diagnosed with DVT, which did not show a significant difference (p = 0.721). However, the two groups differ significantly in the transfusion rate (p < 0.001, 50.0% in the TXA group, 91.7% in the control group). Conclusions: The incidence of DVT, whether symptomatic or asymptomatic, was not affected by the use of topical TXA. The postoperative transfusion rate was reduced in the TXA group. Topical TXA could be applied safely even in patients who had been known to be at high risk.

Abstract
The purpose of this study was to observe the necessity of bed exercise therapy in the rehabilitation of elderly patients after hip replacement and to analyze whether bed exercise therapy has an impact on patients' psychological scores, hip function and postoperative complications. From January 2018 to January 2021, a total of 539 patients with end-stage femoral head necrosis or hip osteoarthritis were retrospectively analyzed. According to the method of postoperative rehabilitation exercise, patients were divided into 2 groups: Group A (routine gait) and Group B (bed exercise). There was no significant difference in general information between the 2 groups. There was no significant difference in baseline pain scores between patients in Group A and Group B (25.2 ± 9.6 vs 24.8 ± 10.4, P = .429). However, at 5 weeks post-operatively, the pain scores of patients in Group A were significantly higher than those in Group B (38.6 ± 7.7 vs 34.1 ± 8.1, P = .016). At 17 weeks post-operatively, the difference between Group A and Group B remained (40.9 ± 6.9 vs 37.5 ± 7.5, P = .041). Similar to the pain score, the hip function score compared between the 2 groups was significantly different at 5 weeks (39.7 ± 8.4 in Group A, 45.9 ± 9.2 in Group B, P < .001) and 17 weeks post-operatively (41.5 ± 7.6 in Group A, 47.2 ± 8.8 in Group B, P < .001). At 17 weeks post-operatively, between the 2 groups, only the range of motion (ROM) of abduction showed no significant difference. Patients in Group B exhibited a better ROM in any other movement posture. The results showed that compared with Group A, bed exercise rehabilitation training could reduce the incidence of deep venous thrombosis. This study demonstrates that bed exercise can improve the hip function and quality of life of elderly patients with total hip arthroplasty (THA) at an early postoperative stage. It can reduce the incidence of deep venous thrombosis of the lower limbs after surgery. For these patients, systematic bed exercise rehabilitation training is recommended in the early postoperative period.

Abstract
Previous studies have defined risk factors for development of venous thromboembolisms (VTEs) among patients with lower extremity orthopedic trauma. Limited data exist on this risk after upper extremity orthopedic trauma. A total of 269,137 incidents of upper extremity orthopedic trauma (fractures of the clavicle, scapula, humerus, elbow, or lower arm) were identified in the State Inpatient Database for 4 states included in the analysis (California, Florida, New York, and Washington) from 2006 to 2014. These patients were split into 2 cohorts, a derivation cohort (California and New York) and a validation cohort (Florida and Washington). Univariate and multivariate logistic regression analyses of risk factors for VTE within 90 days of discharge in the derivation group were used to develop the Thromboembolic Risk after Upper Extremity Trauma (TRUE-T) scale. Linear regression was used to determine fit of the TRUE-T scale to the 2 cohorts. We found that 2.61% of patients in the derivation cohort and 2.72% of patients in the validation cohort had a VTE within 90 days of discharge. Risk factors associated with increased rates of VTE were age older than 40 years, Medicare payer, anemia, chronic lung disease, coagulopathy, heart failure, malignancy, obesity, renal failure, head injury, chest injury, abdominal injury, rib fracture, humerus fracture, elbow fracture, and closed reduction. Application of the TRUE-T scale to the validation cohort showed an R2 value of 0.88. The patient factors, concomitant injuries, and fracture treatment modalities included in the TRUE-T scale can be used to identify patients at increased risk for VTE after upper extremity orthopedic trauma.

Abstract
Patients with versus without atopic dermatitis may have a greater risk of cardiovascular events, and the risk increases with severity of atopic dermatitis. The incidence of cardiovascular events in the population of patients with moderate-to-severe atopic dermatitis is largely unknown. This retrospective study evaluates incidence rates of cardiovascular events in patients aged ≥12 years with moderate-to-severe atopic dermatitis in a cohort of Kaiser Permanente Northern California health care system members without recognized risk factors for adverse events. Patients with moderate-to-severe atopic dermatitis, as defined by dermatologist-rendered code and prescription history between 2007 and 2018, were included. Major adverse cardiovascular events, venous thrombotic events, deep vein thrombosis, and pulmonary embolisms were identified via International Classification of Diseases codes. Stratification variables included age, sex, race, smoking history, and diabetes. Incidence rates per 1000 person-years were calculated by the number of patients with an incident event divided by the total person-years of observation. Among 8197 patients with moderate-to-severe atopic dermatitis, incidence rates per 1000 person-years (95% confidence interval) for major adverse cardiovascular events, venous thrombotic events, deep vein thrombosis, and pulmonary embolism were: 2.6 (2.1-3.2), 2.0 (1.5-2.5), 1.6 (1.2-2.1), and 0.7 (0.5-1.0), respectively. Incidence rates for all events were higher for older versus younger patients, patients with versus without diabetes, former smokers versus patients who had never smoked, and men versus women, except for pulmonary embolisms, which were higher in women. This study estimated the incidence of cardiovascular events in patients with moderate-to-severe atopic dermatitis and provides valuable information for clinicians.

Abstract
Objective: To explore the outcome of the pediatric-to-adult liver transplantation, including postoperative complications and relevant factors which affecting graft survival. Methods: Data of 55 patients undergoing pediatric-to-adult liver transplantation at the First Affiliated Hospital of Zhejiang University between January 2015 and August 2021 were retrospectively analyzed. The donors consisted of 34 males and 21 females, and the age was (11.8±4.7) years (range: 1 to 17 years). Among the cases,17 cases (30.9%) were donation of brain death,32 cases (58.2%) were donation of cardiac death, and 6 cases (10.9%) were donation after brain death plus cardiac death. The recipients consisted of 32 males and 23 females, and the age was (51.6±10.1) years (range: 27 to 70 years). Among the recipients,10 cases (18.2%) were ABO-incompatible liver transplantation.The influencing factors of early graft survival were analyzed by Student t test,Mann-Whitney U test or χ2 test,respectively.Survival curve was drawn by Kaplan-Meier method.Logistic multivariate analysis was used to analyze the independent relevant factors of early postoperative graft loss. Results: Up to October 31,2021,the follow-up time (M(IQR)) was 36.0(43.1)months(range:5.9 to 81.7 months).There were 13 cases with graft loss (two of them underwent re-transplantation due to acute liver failure).The monofactor analysis indicated that cold ischemia time and donor-recipient blood group matching were the relevant factors affecting the early graft survival rate(both P<0.05).Logistic multivariate analysis showed that cold ischemia time and history of recipient gastrointestinal bleeding were independent relevant factors(both P<0.05).Postoperative hepatic artery thrombosis occurred in 3 cases(5.5%), portal vein thrombosis diagnosed in 4 cases(7.3%), portal vein stenosis occurred in 2 cases(3.6%),biliary complications diagnosed in 7 cases(12.7%), and small liver syndrome was found in 8 cases(14.5%). Conclusions: Adult liver transplantation with pediatric donor liver is an effective method to treat end-stage liver disease.Cold ischemia time and history of recipient gastrointestinal bleeding were independent relevant factors for the early graft survival.

Abstract
Classical myeloproliferative neoplasm (MPN) related thrombosis mainly affects elderly patients and often involves arterial circulation, while, MPN-visceral venous thrombosis (SVT) mainly affects young women, and is closely associated with JAK2V617F mutation but not closely with CALR mutation. The pathogenesis of MPN-SVT is not only related to JAK2V617F mutation and vascular endothelial damage, but also needs further research to determine the machanism. JAK2V617F mutation is the most common in MPN-SVT clinically. Patients with non-cirrhotic SVT need to detect MPN mutation, while the detection of CALR or MPL mutation needs to be combined with clinical judgment. At present, the main treatment strategies of MPN-SVT are JAK inhibitors, supplementation of anticoagulants and treatment of portal hypertension. This article reviews the latest research progress on the epidemiology, pathogenesis, diagnosis and treatment strategies of MPN-SVT.

Abstract
OBJECTIVES To summarize cases of venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT) among coronavirus disease (COVID-19) patients and discuss their symptoms, diagnostic method, clinical features, and prognosis. METHODS All major databases were searched for relevant studies published between December 1, 2019 and May 5, 2021. RESULTS A total of 233 articles were identified, 22 describing 48 patients were included. A total of 79.1% had PE and 20.9% had DVT. Most patients were men, with a mean age of 56 years. Comorbidities were present in 70.8%, and 85.4% had at least one risk factor of VTE. 56.3% had received anticoagulation therapy. Most patients were treated in the general ward. Complications occurred in 27.1% of the patients, and recovery was achieved in 80.4%. CONCLUSION Venous thromboembolism must be suspected even in patients who had received prior anticoagulant regimens or in stable cases, especially in males, the elderly, and patients with comorbidities and high D-dimer levels.

Red Cell Distribution Width-to-High-Density Lipoprotein Cholesterol Ratio (RHR): A Promising Novel Predictor for Preoperative Deep Vein Thrombosis in Geriatric Patients with Hip Fracture. Clin Interv Aging 2022; 17:1319-1329. [PMID: 36072306 PMCID: PMC9443816 DOI: 10.2147/cia.s375762] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 08/22/2022] [Indexed: 11/24/2022] Open
Abstract
Background Deep vein thrombosis (DVT) is a devastating complication in geriatric patients before hip fracture surgery, and the predictive value of red cell distribution width (RDW) and high-density lipoprotein cholesterol (HDL-C) for DVTs after hip fracture remains to be established. This study aimed to assess the predictive value of RDW, HDL-C, and RDW-to-HDL-C ratio (RHR) in preoperative DVTs screening. Methods We retrospectively analyzed the data of geriatric patients (≥65 years old) admitted for hip fracture surgery between 2015 and 2020. The receiver operating characteristic (ROC) curve and related parameters were used to evaluate the predictive value of the biomarkers. Patients were divided into two groups according to the cutoff value of RHR, and propensity score matching (PSM) and subgroup analyses were performed to assess the true correlations between RHR and DVT. Results Among 2566 eligible patients included, we identified RDW with the area under ROC curve (AUC) of 0.532, cut-off value of 15.89, specificity of 88.2%, sensitivity of 18.2%, HDL-C with AUC of 0.574, cut-off value of 1.20, specificity of 55.6%, sensitivity of 59.3%, and RHR with AUC of 0.578, cut-off value of 13.45, specificity of 71.3%, sensitivity of 43.4%. RHR (>13.45) was independently associated with 1.54-fold risk (95% CI: 1.11–2.14, P=0.011) of DVTs among the post-PSM cohort. And compared with the counterparts, the relative risk of RHR associated with DVT was higher in the subgroups of aged 65–79 years (1.61 vs 1.45), non-hypoproteinemia (2.70 vs 1.29), non-diabetic (1.58 vs 1.41), non-hypertension (2.40 vs 1.06), ASA score I-II (2.38 vs 1.04), and femoral neck fracture (1.70 vs 1.50). Conclusion RDW, HDL-C and RHR were valuable biomarkers in predicting preoperative DVTs in geriatric patients with hip fracture, and RHR would be more efficient in the subgroups of younger age, better medical condition or femoral neck fracture.

Abstract
Objectives Patients with laboratory or clinical manifestations suggestive of antiphospholipid syndrome (APS) but not fulfilling the classification criteria constitute a clinical challenge. This study aims to compare non-criteria APS (NC-APS) with definite APS in terms of clinical manifestations, therapies, and outcomes. Methods A systematic review of observational studies comparing definite and NC-APS was performed searching four electronic databases. Data on clinical manifestations, therapies and clinical outcomes was extracted. Results Sixteen studies, assessing a total of 3,798 participants, were included. Seven out of 10 studies found no significant difference in the prevalence of arterial or venous thrombosis between definite and NC-APS, with two studies on seronegative APS also finding no difference in thrombosis recurrence. Seven out of 12 studies found no significant difference in the prevalence of obstetric manifestations between groups, with the remaining exhibiting conflicting results. In 9 studies comparing treatment frequency in obstetric patients, all but one described similar treatment frequency, with the percentage of NC-APS treated during pregnancy ranging from 26% to 100%. In 10 studies comparing pregnancy outcomes of NC-APS versus definite APS, 7 found similar successful pregnancies/live births. Additionally, 5 studies described improvement of live births in both groups with treatment, with three signalling aspirin monotherapy as efficacious as combination therapy in NC-APS. Conclusion This review hints at an absence of marked differences in most evaluated parameters between definite and NC-APS, emphasizing the value of a more active follow-up of these patients. The low-quality available evidence highlights the need for well-defined NC-APS populations in future studies.

Ginsenoside Rg5 allosterically interacts with P2RY12 and ameliorates deep venous thrombosis by counteracting neutrophil NETosis and inflammatory response. Front Immunol 2022; 13:918476.

Abstract
Background Deep venous thrombosis (DVT) highly occurs in patients with severe COVID-19 and probably accounted for their high mortality. DVT formation is a time-dependent inflammatory process in which NETosis plays an important role. However, whether ginsenoside Rg5 from species of Panax genus could alleviate DVT and its underlying mechanism has not been elucidated. Methods The interaction between Rg5 and P2RY12 was studied by molecular docking, molecular dynamics, surface plasmon resonance (SPR), and molecular biology assays. The preventive effect of Rg5 on DVT was evaluated in inferior vena cava stasis–induced mice, and immunocytochemistry, Western blot, and calcium flux assay were performed in neutrophils from bone marrow to explore the mechanism of Rg5 in NETosis via P2RY12. Results Rg5 allosterically interacted with P2RY12, formed stable complex, and antagonized its activity via residue E188 and R265. Rg5 ameliorated the formation of thrombus in DVT mice; accompanied by decreased release of Interleukin (IL)-6, IL-1β, and tumor necrosis factor-α in plasma; and suppressed neutrophil infiltration and neutrophil extracellular trap (NET) release. In lipopolysaccharide- and platelet-activating factor–induced neutrophils, Rg5 reduced inflammatory responses via inhibiting the activation of ERK/NF-κB signaling pathway while decreasing cellular Ca2+ concentration, thus reducing the activity and expression of peptidyl arginine deiminase 4 to prevent NETosis. The inhibitory effect on neutrophil activity was dependent on P2RY12. Conclusions Rg5 could attenuate experimental DVT by counteracting NETosis and inflammatory response in neutrophils via P2RY12, which may pave the road for its clinical application in the prevention of DVT-related disorders.

Abstract
Objective To compare the early clinical effects of unilateral biportal endoscopic lumbar interbody fusion (ULIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF)on single-segment lumbar stenosis with instability. Methods The patients who had single-segment lumbar spinal stenosis with instability and were treated in our hospital from August 2020 to May 2021 were selected.According to the operation methods,they were classified into ULIF group and MIS-TLIF group.The operation duration,hospital stay after operation,perioperative blood loss (drainage volume 48 h after operation,total blood loss),creatine kinase,inflammatory cytokines (C-reactive protein,interleukin-6),D-dimer,and the incidence of lower-extremity venous thrombosis were compared between the two groups.The visual analogue scale and Oswestry disability index were used to evaluate the functional recovery of the two groups in 1 week,1 month,and 3 months after operation. Results The ULIF group had longer operation duration (P<0.001) and shorter hospital stay after operation (P=0.022)than the MIS-TLIF group.The drainage volume 48 h after operation and total blood loss in ULIF group were lower than those in MIS-TLIF group (all P<0.001).The levels of creatine kinase (all P<0.001),C-reactive protein (P<0.001,P=0.002),and interleukin-6 (P=0.003,P<0.001) in ULIF group were lower than those in MIS-TLIF group on the 1st and 3rd day after operation.However,the D-dimer in ULIF group was insignificantly different from that in MIS-TLIF group on the 1st and 3rd day after operation (P=0.117,P=0.683).Lower-extremity venous thrombosis occurred in neither group.The score of visual analogue scale showed no significant difference between the two groups 1 week,1 month,and 3 months after operation (P=0.447,P=0.578,P=0.538),so did the Oswestry disability index (P=0.832,P=0.797,P=0.619). Conclusion ULIF shows similar clinical effect on single-segment lumbar stenosis with instability to MIS-TLIF,which features less bleeding,mild inflammation,mild muscle injury,but long operation duration.

Prevention of venous thromboembolic events in patients with lower leg immobilization after trauma: Systematic review and network meta-analysis with meta-epsidemiological approach. PLoS Med 2022; 19:e1004059.

Abstract
BACKGROUND Lower limb trauma requiring immobilization is a significant contributor to overall venous thromboembolism (VTE) burden. The clinical effectiveness of thromboprophylaxis for this indication and the optimal agent strategy are still a matter of debate. Our main objective was to assess the efficacy of pharmacological thromboprophylaxis to prevent VTE in patients with isolated temporary lower limb immobilization after trauma. We aimed to estimate and compare the clinical efficacy and the safety of the different thromboprophylactic treatments to determine the best strategy. METHODS AND FINDINGS We conducted a systematic review and a Bayesian network meta-analysis (NMA) including all available randomized trials comparing a pharmacological thromboprophylactic treatment to placebo or to no treatment in patients with leg immobilization after trauma. We searched Medline, Embase, and Web of Science until July 2021. Only RCT or observational studies with analysis of confounding factors including adult patients requiring temporary immobilization for an isolated lower limb injury treated conservatively or surgically and assessing pharmacological thromboprophylactic agents or placebo or no treatment were eligible for inclusion. The primary endpoint was the incidence of major VTE (proximal deep vein thrombosis, symptomatic VTE, and pulmonary embolism-related death). We extracted data according to Preferred Reporting Items for Systematic Reviews and Meta-analyses for NMA and appraised selected trials with the Cochrane review handbook. Fourteen studies were included (8,198 patients). Compared to the control group, rivaroxaban, fondaparinux, and low molecular weight heparins were associated with a significant risk reduction of major VTE with an odds ratio of 0.02 (95% credible interval (CrI) 0.00 to 0.19), 0.22 (95% CrI 0.06 to 0.65), and 0.32 (95% CrI 0.15 to 0.56), respectively. No increase of the major bleeding risk was observed with either treatment. Rivaroxaban has the highest likelihood of being ranked top in terms of efficacy and net clinical benefit. The main limitation is that the network had as many indirect comparisons as direct comparisons. CONCLUSIONS This NMA confirms the favorable benefit/risk ratio of thromboprophylaxis for patients with leg immobilization after trauma with the highest level of evidence for rivaroxaban.

Abstract
Introduction One of the rare but potentially serious side effects of COVID-19 vaccination is arterial and venous thrombosis. Acute ischemic stroke (AIS) cases have been reported post COVID-19 vaccination. Herein, we systematically reviewed the reported cases of AIS after COVID-19 vaccination. Method This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. We searched PubMed and Scopus until April 14, 2022 to find studies that reported AIS post COVID-19 vaccination. Results We found 447 articles. From those, 140 duplicates were removed. After screening and excluding irrelevant articles, 29 studies (43 patients) were identified to be included. From all cases, 22 patients (51.1%) were diagnosed with AIS associated with Vaccine-induced immune thrombotic thrombocytopenia (VITT). Among AIS associated with VITT group, all received viral vector vaccines except one. The majority of cases with AIS and VITT were female (17 cases, 77.2%) and aged below 60 years (15 cases, 68%). Fourteen patients (32.5%) had additional thrombosis in other sites. Four of them (0.09%) showed concurrent CVST and ischemic stroke. Hemorrhagic transformation following AIS occurred in 7 patients (16.27%). Among 43 patients with AIS, at least 6 patients (14%) died during hospital admission. Conclusion AIS has been reported as a rare complication within 4 weeks post COVID-19 vaccination, particularly with viral vector vaccines. Health care providers should be familiar with this rare consequence of COVID-19 vaccination in particular in the context of VITT to make a timely diagnosis and appropriate treatment plan.

Abstract
INTRODUCTION Eight hundred and fifty-eight consecutive osteotomies around the knee joint were analyzed retrospectively to detect intra- and early postoperative complications in a period of 4 weeks postoperative. Indications for osteotomy were unilateral gonarthritis or torsional deformities resulting in femoropatellar instability or anterior knee pain. MATERIALS AND METHODS Etiology of deformity, technique and mode of correction and level of osteotomy were registered. Complications were detected and divided in minor complication (superficial wound infection, and deep-vein thrombosis) and major complication (compartment syndrome, deep infection, and vascular lesion). RESULTS Fifteen major (1.7%) and 17 minor complications (2.0%) were detected: 5 vascular lesions (0.58%), 4 compartment syndromes (0.47%) and 6 deep infections (0.70%), 14 superficial wound infections (1.6%) and 3 deep-vein thrombosis (0.35%). In posttraumatic osteotomies and continuous corrections, risk for a superficial wound infection was significantly higher and with osteoclasia risk for vascular lesion was higher compared to osteotomy with oscillating saw. No difference was found for anatomical level of osteotomy and for the other complications in terms of etiology of deformity, technique of osteotomy and mode of correction. CONCLUSION Osteotomy around the knee is a safe procedure in the treatment of unicompartmental gonarthritis in terms of intra- and postoperative complications. Major complications are rare. Pit falls for compartment syndromes (LCW and torsional corrections) have to kept in mind. There is no difference in frequency of complications between HTO and supracondylar osteotomies. Risk for superficial wound infection is higher in posttraumatic osteotomies and with continuous corrections. Osteoclasia contains a higher risk for vascular lesion compared to oscillating saw.

Abstract
OBJECTIVE The aim of this study is to compare the risk of venous thromboembolic events (VTE) between patients suspending and continuing estrogen therapy perioperatively, in male to female gender-affirming surgery (vaginoplasty). MATERIALS AND METHODS The authors conducted a systematic review and meta-analysis of existing research on male to female gender-affirming study, which compared the risk of VTE among the usage of estrogen perioperatively. RESULTS A total of 209 studies were identified as potentially eligible among PubMed, Embase, and Cochrane library databases. Among the studies, 191 studies were excluded due to their abstract inappropriateness. Out of the remaining 18 studies, only 3 articles were eligible and were finally included. Meta-analysis was performed and showed odds ratio of 0.77 (95% CI: 0.04, 14.01). CONCLUSIONS Perioperative estrogen therapy does not increase VTE risk on male to female gender-affirming surgery. Therefore, estrogen therapy may be continued perioperatively in vaginoplasty. More prospective studies are needed.

Abstract
Antiphospholipid syndrome (APLS) is an autoimmune condition which commonly manifests as an arterial or venous thrombosis affecting medium to large vessels, with the presence of antiphospholipid antibodies. APLS can be a primary disease by itself, or secondary to other autoimmune diseases, such as Systemic Lupus Erythematosus (SLE). Catastrophic APLS is a rare but a fatal sequelae of APLS, affecting up to three or more organs, and progresses rapidly with a high mortality rate. We report a case of catastrophic APLS in a young woman with underlying SLE who presented to us with multiple cranial nerve palsies due to bilateral pontine infarct, and eventually developed deep vein thrombosis and pulmonary embolism during the course of the illness. She was treated with high dose corticosteroids and intravenous cyclophosphamide with biochemical improvement. In this case report, we would like to highlight the fact that our patient had bilateral pontine infarcts as the initial presentation, with no inciting events and antiphospholipid antibodies were negative during the acute illness.

Abstract
Metformin is hypothesized to protect against the risk of venous thromboembolism (VTE); however, there is a paucity of data supporting this hypothesis. Among individuals aged 40-90 years with a diagnosis of type 2 diabetes in the Health Improvement Network database (2000-2019), we compared the risks of incident VTE, pulmonary embolism, and deep vein thrombosis among metformin initiators with those among sulfonylurea initiators. Individuals were followed from their first prescription refill to an incident VTE, drug discontinuation, switching or augmenting, plan disenrollment, or the end of the study, whichever occurred first. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using the Cox model, adjusting for confounders using inverse probability of treatment weighting. Among 117,472 initiators of metformin and 13,835 initiators of sulfonylureas, 555 (1.3/1,000 person-years) and 75 (2.1/1,000 person-years) VTE cases occurred in each group, respectively. The multivariable-adjusted HR was 0.65 (95% CI: 0.51, 0.84). The corresponding risks for pulmonary embolism (adjusted HR = 0.71, 95% CI: 0.50, 1.01) and deep vein thrombosis (adjusted HR = 0.64, 95% CI: 0.48, 0.87) were also lower in metformin initiators than in sulfonylurea initiators. Our study provided empirical evidence to support a lower risk of VTE after initiation of metformin as compared with sulfonylureas among patients with type 2 diabetes.
