Thrombocytopenia is a tough complication after hematopoietic stem cell transplantation (HSCT) with elusive pathogenesis and lack of well-established therapies. Thrombopoietin receptor agonists (TPO-RAs) have been used for thrombocytopenia post HSCT in recent years, but the outcomes remain debatable. We conducted this meta-analysis and systematic-review to evaluate the efficacy and safety of TPO-RAs for platelet recovery after HSCT. We searched PubMed, EMBASE, and Cochrane databases for studies on the application of TPO-RAs (eltrombopag and romiplostim) in the settings of primary or secondary thrombocytopenia after HSCT by 17 March 2021. Efficacy outcomes included response rate and survival rate, and adverse events were also evaluated. A total of 19 studies involving 378 patients were included. Selleckchem Gamcemetinib The pooled response rate was 73% (95%CI 68-78%), which was significantly higher than recombinant human thrombopoietin (rhTPO) (27.8%). The pooled survival rate was 66% (95%CI 54-77%), and infection was found to be the main cause of death. In addition, the pooled rate of adverse events was 3% (95%CI 1-7%), with no severe adverse events reported. TPO-RAs could effectively and safely promote the recovery of platelets in patients after HSCT.The effect of a combination of two pesticides, carbendazim (CBZ) and imidacloprid (IMI), was investigated on mesenchymal stem cells derived from the bone marrow of buffalo (bMSCs). The bMSCs were exposed to the CBZ (2.25 µM, 4.49 µM, and 8.98 µM) and IMI (0.81 mM, 1.61 mM, and 3.22 mM) alone as well as in combinations. The bMSCs were found to be positive for the stem cell markers, AP, CD73, and OCT4. The bMSCs showed a significant reduction (p ≤ 0.05) in cell viability, and status of anti-oxidants while a significant increase (p ≤ 0.05) in the level of LDH, ALP, and CK-MB in CBZ and IMI-treated groups. A significant increase (p ≤ 0.05) was noticed in LPO, O2─ radical, total ROS, loss of ΔΨm, apoptotic index, and DNA damage in CBZ and IMI-treated groups. A low-dose combination group showed an elevated effect compared to the groups treated with the single pesticide. The interaction index was calculated for CBZ-IMI combined treatment groups on various parameters that showed the majority of antagonist effects. Present findings confirmed that CBZ and IMI-induced cytotoxicity in bMSCs was mediated via ROS production, altered ΔΨm and LPO along with depressed antioxidant status which was responsible for cell apoptosis and cell damage. This study suggested that CBZ and IMI had a dose-dependent toxic effect when the pesticides were used alone, while, co-exposure to both the pesticides simultaneously had an antagonist or non-additive effect on buffalo bMSCs at lower dose combinations and they induced a potentiating effect at high-dose combination.The aim of the present study was to examine and compare knowledge regarding concussion among parents of youth soccer players, ages 5-17, from the United States, Israel, and Sicily. link2 Results revealed parents from the United States were more knowledgeable than Israeli and Sicilian parents and were more likely to have a previous history of concussion in their children, themselves, and their social contacts. The success of concussion education, programming, and legislation in the US may account for the greater knowledge of US parents and is reason to advocate for similar resources for youth athletes internationally.In this study, the genotoxic activity of acetone and aqueous extracts of two species of genus Artemisia (Artemisia vulgaris L. and Artemisia alba Turra), and possible role of their polyphenolic composition in the observed activities were investigated. Polyphenolic contents were evaluated by high-performance liquid chromatography (HPLC-PDA), while the genotoxic activity was tested using cytokinesis block micronucleus (CBMN) assay on human peripheral blood lymphocytes (PBLs) in vitro. HPLC-PDA showed that both A. alba extracts were richer in polyphenolic contents than A. vulgaris extracts. The acetone A. alba extract was the richest of polyphenolic content where we detected six phenolic acids and two flavonoids. CBMN assay showed that aqueous extract of A. vulgaris significantly increased micronucleus (MN) frequency in the PBLs treated with all tested concentrations (10, 50, 100, and 250 µg/mL), while A. alba did not significantly affect the mean MN frequency. Further, both acetone extracts were genotoxic in all tested concentrations, except the lowest tested (10 µg/mL) of A. alba. All tested extracts affected the nuclear division index (NDI) except the aqueous A. alba extract (p  less then  0.05). Based on our results, we can conclude that both acetone and aqueous A. vulgaris extracts and A. alba acetone extract were genotoxic in PBLs in vitro. A. alba aqueous extract was not genotoxic and cytotoxic in tested concentrations. We suggest that the aqueous extract of A. alba can be used in treatment, which has been confirmed by traditional medicine, but with a high dose of caution and not in high concentrations.
The quest toward more effective treatments for bipolar disorder (BD) solicits novel drugs and further research on the underpinning neurobiology. The present review aims to critically appraise the existing evidence about the pharmacological treatment of BD toward the development of novel treatment avenues.

The present review appraises animal and human studies concerning both the currently available psychotropic drugs, and the general medicine drugs which may represent a path toward the development of novel drugs for BD. PubMed and Scopus were last accessed on February 20
, 2021 for records indexed upon inception relevant to the pharmacological treatment of BD. Immune-modulating agents, anti-inflammatory agents, and glutamate antagonists represent the most intriguing potential targets for the development of new drugs for BD, thus receiving critical appraisal in the present text.

Regardless of the neurobiological pathways worthy of investigation toward the development of experimental drugs for BD, several unmet needs need to be addressed first. In particular, several biomarkers are altered in BD. However, it is the opinion herein expressed by the authors that it remains uncertain what comes first, that is peripheral changes or the disease.

Method The study is inspired by a process-tracing design for case study with a focus on the non-medical measures and surveillance strategies implemented by the three countries. The comprehensive collection and study of national documents formed the basis of the document analysis. link3 Results The Danish strategy was to prolong the transmission period, preventing high numbers of infected cases from impacting their healthcare capacity. The government's strategy was characterized by strict governance elements, health guidelines and behavioural recommendations. In Serbia, the main strategy was to prevent the spread and control of the infectious disease by shifting all human and material resources towards the function of controlling the spread. Serbia applied the strictest measures in the fight against coronavirus in relation to other countries in the region and in Europe. The Swedish strategy focused more on recommendations than requirements to motivate the public to modify their behaviours voluntarily. Sweden's loose pandemic strategy implementation focused on voluntary and stepwise action rather than legislation and compulsory measures. Conclusions The public health policies and actions implemented to prevent community spread of COVID-19 in Denmark, Serbia and Sweden varied during the first five months of the pandemic. The differences in their response were due to delays in implementation, inconsistencies in perspectives towards the outbreak and the capacity of each country in terms of their pandemic preparedness and response.
In Ethiopia, the burden of HIV/AIDS is a public health issue that requires significant control of transmission. Once an infection has been established, determinants influence people living with HIV to disclose or not their HIV-positive status to sexual partners. This study assessed the proportion and associated factors of people living with HIV's disclosure status to sexual partners.

CRD42020149092 is the protocol's registration number in the PROSPERO database. We searched PubMed, Scopus, African Journals Online, and Google Scholar databases. For the subjective and objective assessment of publication bias, we used a funnel plot and Egger's regression test, respectively. The

statistic was used to assess variation across studies. Meta-analysis of weighted inverse variance random-effects model was used to estimate the pooled proportion. We conducted subgroup and sensitivity analyses to investigate the cause of heterogeneity and the impact of outliers on the overall estimation, respectively. A trend analot disclose their HIV-positive status to sexual partners. HIV-positive status disclosure was influenced by psychosocial factors. A multidimensional approach is required to increase seropositive disclosure in Ethiopia.
In Ethiopia, more than one-fourth of adults living with HIV did not disclose their HIV-positive status to sexual partners. HIV-positive status disclosure was influenced by psychosocial factors. A multidimensional approach is required to increase seropositive disclosure in Ethiopia.Follicular lymphoma (FL) usually has an indolent course and presents with painless, waxing and waning lymphadenopathy in the absence of systemic symptoms. It is uncommon for FL to present outside of lymph nodes, although it can develop in the gastrointestinal tract, skin, thyroid, and testes. Central nervous system (CNS) involvement in FL is rare. Most CNS lymphomas are diffuse large B-cell lymphoma, although Burkitt lymphoma, lymphoblastic lymphoma, and peripheral T-cell lymphoma are also observed. These tumors usually involve white matter but may also involve gray matter. Lymphomas of the dura are very uncommon and are usually mucosa-associated lymphoid tissue lymphomas. Here, we present a case of FL of the dura arising in a 62-year-old woman that was responsive to chemotherapy. According to a literature review, there have been 15 previously reported cases of FL of the dura. Dural FL has been most frequently treated with radiation and chemotherapy. Patients were still alive in all cases in which follow-up was reported. Although the sample size is small, these data suggest that dural FL, like other forms of FL, is an indolent disease that is associated with prolonged survival despite usually being incurable.
