Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The clinical manifestations of COVID-19 include dry cough, difficult breathing, fever, fatigue, and may lead to pneumonia and respiratory failure. There are significant gaps in the current understanding of whether SARS-CoV-2 attacks the CNS directly or through activation of the peripheral immune system and immune cell infiltration. Although the modality of neurological impairments associated with COVID-19 has not been thoroughly investigated, the latest studies have observed that SARS-CoV-2 induces neuroinflammation and may have severe long-term consequences. Here we review the literature on possible cellular and molecular mechanisms of SARS-CoV-2 induced-neuroinflammation. Activation of the innate immune system is associated with increased cytokine levels, chemokines, and free radicals in the SARS-CoV-2-induced pathogenic response at the blood-brain barrier (BBB). BBB disruption allows immune/inflammatory cell infiltration into the CNS activating immune resident cells (such as microglia and astrocytes). This review highlights the molecular and cellular mechanisms involved in COVID-19-induced neuroinflammation, which may lead to neuronal death. A better understanding of these mechanisms will help gain substantial knowledge about the potential role of SARS-CoV-2 in neurological changes and plan possible therapeutic intervention strategies.

Purpose To determine the role of lung transplantation in the treatment of patients presenting with bronchogenic carcinoma and end-stage lung disease. Methods An international survey was conducted to determine the outcome of patients with bronchogenic carcinoma in the explanted lung at the time of transplantation. A group of 69 patients was collected from 33 centers. Results Twenty-six patients underwent 29 lung transplantations for advanced multifocal bronchioloalveolar carcinoma (BAC) as the primary indication for transplantation, and 13 developed a recurrence, with an overall 5-year actuarial survival of 39%. Incidental bronchogenic carcinomas classified as stage I (n = 22), II (n = 12), and III (n = 2), or as incidental multifocal BAC (n = 7), were found in the explanted lung of the remaining 43 patients. The 5-year actuarial survival was 51% in patients with stage I carcinomas, and was significantly better than for patients with stage II and III carcinomas (survival of 14%) or with incidental multifocal BAC (survival of 23%). Time from transplantation to recurrence and from recurrence to death was significantly longer in patients with multifocal BAC than in patients with other types of bronchogenic carcinoma. In addition, the site of recurrence was limited to the transplanted lung in 88% of the patients with multifocal BAC, whereas it was always widespread in patients with other types of bronchogenic carcinoma. Conclusion This study demonstrates that long-term survival can be achieved after lung transplantation in patients with stage I bronchogenic carcinoma or with advanced multifocal BAC.

The immunity and immune system functions to fight against infections are significantly impacted by inappropriate food and nutrition. Long term malnutrition is universally considered as the leading cause of immune system deficiency. A substantial proportion of the global population does not meet the recommended daily intake of nutrients. The COVID-19 pandemic has focused attention on the role of the immune system, with health scientists and nutritionists urging people to take supplements and/or eat particular foods (nutrients) to super-charge their immune systems.The immune system is the most complex system of human body. This system is made up of a complex network of structural and functional units like cells, molecules, tissues and organs all working together to safeguard the body as a whole.This precise review provides a chance to go through the efficacy, efficiency and scientific significance of nutritional components and relevant food (especially fruits and vegetables). This will help you keep appropriate food items in your daily meals so that you can get a progressive increment in your body’s defence mechanisms and immunity to fight appropriately against COVID-19. This will also help to decrease your risk for catching the viral infection and/or reducing the chances of having complications from COVID-19.

INTRODUCTION: Carpal tunnel syndrome (CTS) is estimated to be the most frequently seen mononeuropathy, needing surgical intervention. Its prevalence is known to range between 1, and 3 percent. The components contained in this tunnel are the median nerve, four deep digital flexor tendons, as well as four superficial flexors and the tendon of flexor pollicis longus. Between the tendons and bursae an anatomical structure is present called subsynovial connective tissue (SSCT). SSCT absorbs and transmits stress between tendons and the median nerve and it functions as a scaffold for vascular elements. To find out the role of compression or pathologic proliferation of SSCT in the pathogenesis of CTS, we aimed to conduct a study about the surgical technique of this pathology and compared the long- term results of patients operated with or without SSCT excision in our neurosurgery clinic. METHODS: Between 2003 and 2019 we operated 1279 patients at our neurosurgery clinic. Among them 250 patients who had SSCT excision (syn+) were chosen and they were compared with other 250 patients operated without SSCT excision (Syn-). RESULTS: All patients were evaluated preoperatively and 12 months postoperatively based on the results of Boston Carpal Tunnel Syndrome Questionnaire. When pre-, and post-operative results were compared, we didn’t observe a statistically significant intergroup difference. DISCUSSION AND CONCLUSION: Although our primary goal in patients in whom we performed excision of tenosynovium is to relieve the median nerve by increasing decompression, we observed that there was no difference between the two groups in this large-scale study. We think that only liberation of the transverse carpal ligament during surgery will be sufficient.
