Effects of Pleiotrophin (PTN) on the resistance to paclitaxel in ovarian cancer cells
Published on: 23rd February, 2023
The pathogenesis of an ovarian disease is connected with PTN and its receptor protein tyrosine phosphatase receptor Z1 (PTPRZ1). Paclitaxel is the first-line drug for the therapy of ovarian cancer. With the increment of paclitaxel chemotherapy, paclitaxel obstruction happens in the late phase of therapy frequently. By treating A2780 and SKOV-3 cells with PTN, we found the development of the two cell lines was enhanced. Different concentrations of PTN were added to A2780 and SKOV-3 cells treated with paclitaxel and the results of MTT showed that the inhibitory effect of paclitaxel on these two cell lines was weakened. The results of apoptosis assays showed that PTN could slow down the rate of apoptosis and its concentration dependence in both cell lines. To further investigate the impact of PTN on the paclitaxel responsiveness of ovarian malignant growth cells, A2780 and SKOV-3 cells were transfected with sh-PTN-1, sh-PTN-2 and sh-NC plasmids. The results of PCR and Western Blot showed that both RNA-interfering plasmids could inhibit PTN in A2780 and SKOV-3 cells. The results of MTT showed that the inhibitory effect of paclitaxel on cells transfected with sh-PTN-1 expanded compared with the benchmark group. Apoptosis assays showed that the complete apoptosis pace of A2780 and SKOV-3 cells with sh-PTN-1 plasmid induced by paclitaxel was accelerated obviously compared with the benchmark group. To summarize, the results suggested that PTN could enhance the resistance to paclitaxel in ovarian cancer cells, which provides a groundwork for studying on drug resistance of cancer cells to paclitaxel and a new perspective for ovarian cancer therapy.
Health challenges in Indonesia
Published on: 22nd February, 2023
Indonesia is the fourth largest country in the world by population and has made considerable progress since the 1960s in terms of economic growth and structural transformation. But in recent years it has become apparent that the health of the nation is far from satisfactory. The purpose of this article is to review recent literature on health problems in Indonesia and to outline the policy challenges which face the government. Since 2001, the provision of primary health care has been decentralized to sub-provincial levels of government but they lack often lack the resources, and trained staff to provide adequate services to rural populations in particular. The literature suggests that while most health indicators have shown some improvement in recent years, there are still large variations by region and social class. The country is still far from achieving the goal of universal health coverage.
The prevalence and risk factors of chronic kidney disease among type 2 diabetes mellitus follow-up patients at Debre Berhan Referral Hospital, Central Ethiopia
Published on: 20th February, 2023
Background: Chronic kidney disease is a progressive loss in renal function that is more accepted as global public health importance and its magnitude is overgrowing in the least developed countries like Ethiopia. No data was found in Debre Birhan Central Ethiopia on the magnitude of chronic kidney disease among type 2 diabetes patients. Methods: Institution-based cross-sectional study was conducted among 327 at Debre Berhan Referral Hospital from March to June 2019 in Adult (≥ 18 years) type 2 diabetes follow-up patients who volunteered to give informed written consent were included in the study. Systematic random sampling was used. Data were collected by interviews using structured and pre-tested questionnaires. Descriptive statistics of the continuous and categorical variables were done. The bi-variable and multivariable logistic regression was done to show the net effect of explanatory variables on chronic renal disease. Results: A total of 327 study participants were involved in the final analysis. The Prevalence of CKD among type 2 diabetic patients was 15.9%. A significant association was found with age > 60 years [AOR 3.5 (95% CI 1.8-6.8)], alcoholic patients [AOR 2.4 (95% CI 1.2-5.1)], glycated hemoglobin levels above 7% [AOR 2.5 (95 CI 1.5-4.1)], higher level of LDL greater than 100 g/dl [AOR 2.7 (95% CI 1.9-4)] and lower level of HDL [AOR 2.9 (95% CI 1.4-6)].Conclusion: The magnitude of chronic kidney disease among type 2 diabetic follow-up patients was 15.9%. Estimated GFR should be determined for diabetic patients at regular intervals of time for earlier diagnosis of chronic kidney disease.

Prospective evaluation of a computerized algorithm for Vitamin K antagonist drug dose calculation
Published on: 16th February, 2023
Introduction: In an earlier study, we described and validated a VKA dose-finding algorithm (B2A), based on a novel bidirectional factor (BF). We designed a prospective study to evaluate the B2A in a daily care setting. Methods: In this open-label prospective study, we compared the outcomes of the B2A over the year 2020 with the outcomes of the previous year (2019), using regular algorithms. The outcomes were the duration of Time in the Therapeutic Range (TTR), the percentage of automated dose proposals (PAuP) and the percentage of accepted dose proposals (PAcP). The data were obtained from three anticoagulation centers in the Netherlands, in four locations. The outcomes of this study were based on a non-inferiority level.Results: The TTR over the year 2020 was at least non-inferior compared with the standard of care treatment. The percentage of automated proposals increased in all centers to approximately 96% of all dosages. Conclusion: The B2A performs non-inferior compared with the existing algorithms and in some aspects even better.

The complement cascade as a target against SARS-CoV-2-induced pneumonia
Published on: 14th February, 2023
Fox, et al. [1] reported on the relevant cardiopulmonary findings in a series of autopsies of patients deceased from SARS-CoV-2 infection. In particular, regarding the histologic examination of the lungs, they observed bilateral diffuse alveolar damage with a lymphocytic infiltrate, thickened alveolar capillaries, fibrin thrombi within the capillaries and small vessels, and entrapment of neutrophils, without any significant neutrophilic, infiltrate within airways or the interstitium.

Community, health and rehabilitation
Published on: 14th February, 2023
The problems of guaranteeing the best possible social and health services in every part of the world to combat any form of disability and limitation of participation for all, as indicated by international ethical-political documents, are still very great. A critical point that could favour this progress is to enhance the integration between the growing potential of rehabilitation science (medical and clinical evidence, technologies, and training of numerous operators..) and the ability of communities as a whole to stimulate, support and qualify these interventions with the participation of citizens (families, neighbours and associations) who can voluntarily actively carry out important synergistic actions in many fields. This could develop in any socio-economic condition; in developed ones supporting and finalizing any treatment in common life and in developing countries offering competencies and knowledge to the strong funding actions of community projects aimed at populations with disabilities in this part of the World. The community of rehabilitation professionals, national governments and rulers, and international institutions (UN, WHO..) must well understand this aspect and make it their own in training, in the definition of care protocols, in the definition of the organization of socio-health and rehabilitation systems in each country in relation to the different local economic and cultural conditions.
