The case is that of 83 year-old African American man with hypertension, hepatitis C induced decompensated cirrhosis with ascites, end-stage renal disease (ESRD) on hemodialysis, fluid overload with peripheral edema and chronic hypotension. The patient was referred to the dialysis access center of Pittsburgh, PA for evaluation of his prolonged bleeding from the left upper arm brachial-basilic arterial-venous fistula (BBAVF).

Introduction: Endothelial progenitor cells (EPC) are involved in vascular repair and proliferation, contributing to the long-term outcomes of apheretic treatment. Aim of this study was to investigate the relationships between endothelial function, assessed by levels of bone marrow-derived progenitor cells and endothelial response to hyperaemia, and clinical and biohumoral parameters in high vascular risk patients before, immediately after, 24-hours and 72 hours after a single lipid apheresis procedure. Material and Methods: We evaluated lipid profile, endothelial function and endothelial progenitor cells before (T0), immediately after (T1), 24h after (T2) and 72h after (T3) a lipoprotein apheresis procedure, in 8 consecutive patients [Sex: 62.5% M; Age; 63.29(12), mean, (range) years] with a personal history of acute coronary syndrome, symptomatic peripheral arterial disease and elevated plasma levels of lipoprotein (a) [Lp(a)]. Patients were on regularly weekly or biweekly lipoprotein apheresis, and they were treated with the FDA-approved Heparin-induced Extracorporeal LDL Precipitation (H.E.L.P.) (Plasmat Futura, B.Braun, Melsungen, Germany) technique. PAT values were expressed as the natural logarithm (Ln-RHI, normal values≥0.4) of the reactive hyperaemia index (RHI), which is the parameter automatically calculated by the device. Results: We found a reduction in the natural logarithm of reactive hyperaemia index (Ln-RHI), assessed immediately after the procedure (0.57±0.21 vs 0.72± 0.29); difference between T2 and T0 was statistically significant (0.43±0.24 vs 0.72±0.29; p=0.006). Reduction in Ln-RHI values was documented in all patients, two subjects showing a Ln-RHI<0.4 at T1, and four at T2. At T3, PAT values were increased significantly (0.91±0.18) in comparison to T1 and T2, showing a median value higher than at T0. Cd34+/Kdr+ and Cd133+/Kdr+ showed a minimum increase in median values at T1, and a higher increase at T2, in comparison to baseline. Differences in Cd34+/133+/Kdr+ values at different times were not statistically significant. A significant reduction in circulating endothelial cells (CEC) count at T2 in comparison to T0 was found (12.00±8.85 vs 23.86±12.39; p=0.024). Discussion: At 24h and 72h after procedures, we found an improvement in endothelial function, expressed by an increase in PAT values and EPC levels, and by a reduction in CEC.

Related COVID vaccine production many different strategies was followed by the producers. Observing some rare event of thrombosis after some COVID-19 vaccination, it is interesting to verify if the Target used for the manufacturing can be involved in a different procoagulant activity or not. Some vaccine are suspended in some country or under a deep new verify- investigation by the regulatory agency. (EU or USA). This fact it is relevant. The target SPIKE-PROTEIN FULL LENGTH modified or not or towards the RBD domain can be a relevant factor.

Zinc induced pediatric preventing respiratory 2019-nCoV is required that supplementation with zinc gluconate 20 mg in Zn deficient children resulted in a nearly twofold reduction of acute lower respiratory infections as well as the time to recovery. Zinc supplementation in children is associated with a reduction in the incidence and prevalence of pneumonia. Preventing 2019-nCoV pneumonia is required that zinc supplementation alone (10 to 20 mg) for more than 3 months significantly reduces in the rate of pneumonia. zinc pediatric intake may be required to be effective range 10～20 mg/d for 2019-CoV prevention, 10～30 mg/d for reduction of COVID-19 bronchitis, and 20～30 mg/d for recovery from COVID-19 pneumonia, in which Zn2+ could bind with viral surface proteins by Zn2+ions-centered tetrahedrally coordination pattern. On the other hand, for aults, the zinc-homeostatic immune concentration may provide a protective role against the COVID-19 pandemic, likely by improving the host’s resistance against viral infection. 50 mg of zinc per day might provide an additional shield against the COVID-19 pandemic, possibly by increasing the host resistance to viral infection to minimize the burden of the disease. In order to prevent that an outbreak of respiratory sickness caused by a novel coronavirus (COVID-19) has become a serious public threat and disrupted many lives,assessing the efficacy of FDA-approved Zn-ejector drugs such as disulfiram combined with interferon to treat COVID-19 infected patients has been proposed. The key strategies for preventing lung damages include avoiding direct lung infection, altering host-virus interactions, promoting immune responses, diluting virus concentrations in lung tissues by promoting viral migration to the rest of the body, maintaining waste removal balance, protecting heart function and renal function, avoiding other infections, reducing allergic reactions and anti-inflammatory. The interactions had been found on the binding specificity by Zn2+ ions-centered tetrahedral geometric coordination of the inhibitors against 3C and 3C-like proteases. In addition, transient zinc chelation TPEN and EPDTC have been noted as preventing virus replication. Zinc-induced ROS production in COVID-19 respiratory ailment and pneumonia occurs both in children and adults. In children. ROS production in zinc (Ⅱ)-immune pediatric patient with COVID-19 bronchitis and pneumonia cannot be elucidated yet. In adults, zinc induced ROS generation in pulmonary COVID-19 infected cells is that alterations of ROS-producing and scavenging pathways that are caused by respiratory viral infections are implicated in inflammation, lung epithelial disruption, and tissue damage, and, in some cases, even pulmonary fibrosis. The involvement of oxidative stress in cell deaths caused during RNA virus infection and ROS production is correlated with host cell death.

The day before yesterday, it was shameful for some politicians, especially President Trump, to label SARS-CoV2 virus as discriminatory “Chinese Virus”. Politicians should be more professional and graceful, and distance themselves from the independence of the academy if something remains unknown to them. Besides, there were two months for President Trump to prepare the Americans for this Virus [1]; unfortunately, could he have given more attention to his duty of anti-SARS-CoV2 action, despite spending time to defending against the impeachment of his presidency? Besides, in line with this idea, presidential candidate Hillary Clinton wrote: ”The president is turning to racist rhetoric to distract from his failures to take the coronavirus seriously early on, make tests widely available and adequately prepare the country for a period of crisis. Don’t fall for it. Don’t let your friends and family fall for it”.

Introduction: The incidence of STI-HIV/AIDS is on the rise, making adolescents a vulnerable group at risk. Objective: To increase the knowledge and perception of risk about STI-HIV/AIDS, through Educational Intervention in students of the Polytechnic Institute ¨Hermanos Gómez¨ of the Municipality San José de las Lajas, Mayabeque Province. Method: Quasi-experimental study, intervention at the ¨Hermanos Gómez Polytechnic Institute, of the Municipality of San José de la Lajas, through affective, participatory, animation and reflection techniques, the universe being made up of 17 students aged 16-17 years of specialty in Industrial Chemistry, during the period from December 2014 to November 2015. The variables used were: knowledge about STI-HIV/AIDS and perception of risk towards said diseases. Results: after the intervention, an increase in the level of knowledge of the main STIs in the study was evident: Syphilis, Condylomas, HIV/AIDS, Gonorrhea, Trichomonas, Candida Albicans and Herpes simplex, which were adequately identified by 60%; 71% recognized the routes of sexual transmission, 60% the typical clinical manifestations, an increase in the levels of knowledge about the use of condoms to prevent STIs, and in the same way the perception of risk in an 83% after the intervention. Conclusion: After the intervention, there was an increase in knowledge of STIs, transmission routes, clinical manifestations, condom use, and risk perception.

Background: Tetanus continues to threaten the survival of children in spite of it being a vaccine preventable disease. The objective of this study was to determine the prevalence of post-neonatal tetanus, review the vaccination of affected children, complications encountered and the outcome among affected children in a tertiary health institution in southwestern Nigeria. Methods: The study was a retrospective study. Case notes of children outside neonatal life admitted to the Paediatric ward with clinical diagnosis of tetanus between January 2012 and October 2018 were retrieved and evaluated to identify socio-demographic and clinical characteristics. A review of the immunization history and cards was done where the immunization cards were available. Results: 21children with post-neonatal tetanus were admitted over a period of six years (November 2012 to October 2018) with a prevalence of 0.3%. The M:F was 3.2:1. The mean age in years was 10.14 ±3.44 while the age range of the subjects was 4 to 16years. None of the patients had booster doses of tetanus toxoid (TT) outside the infancy period. Nine (42.9%) subjects had no previous TT vaccination, 2 (9.5%) had 3 doses of TT vaccine in infancy but developed tetanus at age ≥9 years, 1(4.8%) subject had a dose of TT while the remaining 9subjects had no proof of previous TT vaccination. The percentage mortality was 19% (4 out of 21). All the patients that died had no prior record of TT vaccination. Complications identified included laryngeal spasm and autonomic dysfunction. Conclusion: Post-neonatal tetanus is still common in our locality because booster doses of Tetanus Toxoid are not part of the national immunization schedule. Complete dose of tetanus toxoid vaccination during infancy and booster doses at school entry is necessary and should be part of school health programme to forestall post-neonatal tetanus

In today’s busy world, people don’t even have the time to fall ill. Diseases don’t just demand time but also physical efforts, mental peace, loss of work, distress of loved ones and financial loss. According to a report published in Harvard business review, each year in India, 39 million people are pushed into poverty by out-of-pocket payments for healthcare, with households on average devoting 5.8% of their expenditures to medical care [1].

A thought-provoking debate in the popular literature concerning vaccination has blossomed in recent years [1-6]. While “traditionalists” support universal immunization against a variety of infectious diseases, many influential individuals hold that vaccinations do far more harm than good. The web sites vactruth.com and anhinternational.org are typical web sites to visit to understand their concerns.  More details on the debate, offering commentary on both sides of the issue, can be explored at wikipedia.org/wiki/Vaccine_controversies. In essence, however, those arguing for the universal use of vaccines point to the many millions of lives saved since mass immunization programs were introduced and further argue that resistance to routine vaccination is almost always based on false information. Those arguing against the routine use of vaccines usually either contend that the vaccines are unsafe (often maintaining that vaccine components such as formaldehyde or thimerosal are highly toxic) or alternately argue that governments simply do not have the moral authority to encroach on an individual’s freedom to make medical decisions for themselves or for their children.

SARS-CoV-2 infection is associated with thyroid disorders. It has been reported that myxedema coma (MC) can be complicated with COVID-19. COVID-19-related thyroid disorders consist of a broad spectrum of thyroid dysfunction, from thyrotoxicosis to decompensated hypothyroidism. It is possible that both primary and central thyroid disorders are induced by COVID-19 due to systemic inflammatory and immune responses. We experienced two cases in which patients with COVID-19 developed MC with central hypothyroidism. It is likely that MC affected the severity of COVID-19. It is necessary to consider the existence of MC during SARS-CoV-2 infection. We propose the potential mechanisms.
