Introduction. Patients with brain tumors are at increased risk for the development of venous thromboembolism (VTE). The most effective prevention method today is a combination of mechanical compression of the lower extremities and the introduction of low molecular weight heparin (LMWH). In 2018, an algorithm for the prevention of VTE was introduced in our clinic, which implies the early (in the first 48 h after surgery) administration of LMWH.The study objective is to assess the effect of early LMWH administration on the incidence of intracranial hemorrhage (ICH) after removal of brain tumors.Materials and methods. From January 2014 to December 2019, 3266 patients underwent removal of brain tumors. The group 1 included 2057 patients who were treated in the period before the introduction of the VTE prevention algorithm (2014– 2017), the group 2 included 1209 patients who were treated using this algorithm (2018–2019). In each of the groups, the frequency and timing of ICH were assessed. The severity of complications was assessed according to the F.A.L. Ibanez classification. The data were compared between groups 1 and 2, as well as between patients who received LMWH at the time of ICH and those who did not receive.Results. Patients of the group 1 were prescribed LMWH in 14.3 % of cases, on average on the 4th day after surgery. In this group, 26 (1.26 %) patients developed ICH. Patients of the group 2 were prescribed LMWH in 89 % of cases, on average on the 2nd day. In this group, 15 (1.24 %) patients developed ICH. Severe complications were in 6 (85.7 %) of 7 patients who received LMWH at the time of ICH, and in 25 (73.5 %) of 34 patients who did not receive LMWH (p = 0.66).Conclusion. The widespread use of LMWH for the prevention of VTE during the first 48 h after removal of brain tumors did not lead to an increase in the frequency of ICH. At the same time, patients with ICH who developed during the use of LMWH often had a more severe clinical course.

<p class="abstract"><strong>Background:</strong> Lichen planus (LP) is an immunologically mediated inflammatory disorder involving the skin, nails, hair follicles and mucous membranes. Though several drugs and phototherapy are tried and mentioned in the literature, dermatologists are still depending on corticosteroids, which have various serious side effects on long term usage. Thus, in search for an alternative therapy, the present study is conducted to compare the efficacy of systemic corticosteroids and low dose low molecular weight heparin in management of lichen planus.</p><p class="abstract"><strong>Methods:</strong> 60 patients with biopsy proven LP were selected and divided randomly into two groups with 30 patients each. Group 1 was treated with oral corticosteroids and group 2 was treated with low molecular weight heparin for 8 weeks. Follow up was done for a period of 6 months, at monthly intervals in all patients and any relapses if any were noted.<strong></strong></p><p class="abstract"><strong>Results:</strong> 60 patients with biopsy proven LP were selected and divided randomly into two groups with 30 patients each.

Objective: The most prominent clinical finding in severe COVID-19 patients is endothelial damage. For these reasons, active administration of anticoagulants (such as heparin) is recommended to patients with severe COVID-19. The purpose of this study is to investigate the effects of different doses of low-molecular weight heparin (LMWH) on severe COVID-19 patients. Methods: This study was performed retrospectively in intensive care unit of a tertiary referral hospital. PCR (polymerase chain reaction) positive (+) patients were included in the study. Patients’ demographic data, length of stay in the hospital and intensive care unit, laboratory values (D-dimer, CRP, creatinine) on the last day of intensive care stay, mortality and invasive mechanical ventilator needs were recorded. Group O: consisted of patients not receiving anticoagulants, and Group 1 received a single daily dose of 40 mg enoxaparin sodium (equivalent to 4000 anti-Xa IU), and Group 2 received 2 daily doses of 1 mg/kg enoxaparin sodium. Results: A total of 191 patients were included in the study. 45% of the patients were female (n: 86), 55% were male. The mean age was found to be 67.6 ± 13.8. Patient numbers; group 0: 12, group 1: 90, group 2: 89. 7-day mortality was 50% in group 0, 22.2% in group 2, and 23.5% in group 3 (p value <0.05). Conclusion: In a recent lung dissection report in critically ill patient with COVID-19; occlusion of pulmonary small vessels and formation of microthrombosis have been demonstrated. Prophylactic doses of LMWH are used more frequently. Some studies have suggested that septic patients may benefit from early diagnosis and specific treatment. As a result; in severe COVID-19 patients with limited mobilization, all doses of LMWH reduce morbidity and mortality.

Abstract Funding Acknowledgements Type of funding sources: None. Background- Low molecular weight heparin (LMWH) and direct oral anticoagulants (DOACs) have been proven to be more effective in the management of venous thromboembolism (MVTE). The efficacy and safety of LMWH or DOACs in treatment of recurrent or malignancy induced VTE is not studied in literature. Objective To compare the efficacy and safety of LMWH and  DOACs in the management of malignancy induced  VTE Methods- Electronic databases ( PubMed, Embase, Scopus, Cochrane) were searched from inception to November  28th, 2020. Dichotomous data was extracted for prevention of VTE and risk of major bleeding in patients taking either LMWH or DOACs. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p &lt; 0.05.  Results- Three studies with 2607 patients (DOACs n = 1301 ; LMWH n = 1306) were included in analysis. All the study population had active cancer of any kind diagnosed within the past 6 months. Average follow-up period for each trial was 6 months. Patients receiving DOACs have a lower odds of recurrence of MVTE as compared to LMWH( OR 1.56; 95% CI 1.17-2.09; P = 0.003, I2 = 0). There was no significant difference in major bleeding among patients receiving LMWH or DOACs  (OR-0.71, 95%CI 0.46-1.10, P = 0.13, I2 = 22%) (Figure 1). We had no publication bias in our results (Egger’s regression p &gt; 0.05). Conclusion- DOACs are superior to LMWH in prevention of MVTE and have similar major bleeding risk as that of LMWH.
