Since January 2020, the coronavirus disease 2019 (COVID-19) pandemic has raged around the world, causing nearly a million deaths and hundreds of severe economic crises. In this scenario, Italy has been one of the most affected countries.
This study investigated significant correlations between COVID-19 cases and demographic, geographical, and environmental statistics of each Italian region from February 26 to August 12, 2020. We further investigated the link between the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and particulate matter (PM) 2.5 and 10 concentrations before the lockdown in Lombardy.
All demographic data were obtained from the AdminStat Italia website, and geographic data were from the Il Meteo website. The collection frequency was one week. Data on PM2.5 and PM10 average daily concentrations were collected from previously published articles. We used Pearson's coefficients to correlate the quantities that followed a normal distribution, and Spearman's coefficienggest creating awareness campaigns for the recirculation of air in enclosed places and to avoid exposure to the cold.
Since SARS-CoV-2 is correlated with historical minimum temperatures and PM10 and 2.5, health authorities are urged to monitor pollution levels and to invest in precautions for the arrival of autumn. Furthermore, we suggest creating awareness campaigns for the recirculation of air in enclosed places and to avoid exposure to the cold.Depression is a mental illness that can have serious implications if left untreated. Studies involving a neurotrophic factor called brain derived neurotrophic factor (BDNF) and its associated signaling pathways have solidified our understanding of the pathophysiology of depression. The objective of this literature review is to gain a better understanding of the mechanism by which reduced levels of BDNF are implicated in depression and how antidepressants facilitate the treatment of depression by increasing BDNF levels. The specific approach is to learn about the key involvements of BDNF and its receptor TrkB (tropomyosin receptor kinase B) and how their interactions and subsequent intracellular signaling cascades bring about enhanced neuroplastic changes. In this literature review, we searched for past review articles focusing on BDNF. We collected data using PubMed and created a summary of our findings. The results showed that stress and depression through the reduction of BDNF levels contribute to neuroplastic changes while antidepressants through enhanced BDNF levels are able to generate positive neuroplastic outcomes and thereby help resolve depressive symptoms. In this paper, we will delve into how a better understanding of the neural circuitry involving BDNF will enable us to both understand how current antidepressants work in the limbic regions of the brain as well as search for novel rapid-acting antidepressants to use in clinical practice.Cefepime is a fourth-generation cephalosporin that has multitude of uses in various conditions. Cefepime associated neurotoxicity was first described in 1999. Here, we describe a case in which we appreciated the neuropsychiatric effects of cefepime on a patient who had underlying chronic kidney disease.Corticobasal syndrome is an atypical parkinsonian syndrome consisting of a constellation of clinical findings that can be the result of various etiologies. While most cases are a result of a tauopathy, such as corticobasal degeneration, other etiologies must be considered in the evaluation of patients presenting with corticobasal syndrome. We present a case of a patient presenting with clinical features of corticobasal syndrome due to a prion disease, Creutzfeldt-Jakob disease (CJD), who was initially misdiagnosed due to known pitfalls in the CJD diagnostic criteria. We further discuss this unusual manifestation of CJD presenting as corticobasal syndrome and relevant diagnostic consideration in the evaluation of this entity.Background Marjolin's ulcer (MU) of lower extremities usually presents with scar contracture and functional disability. They often follow an aggressive course and poor outcome, and require early radical removal. Split-thickness skin grafts, local flaps, or amputation are commonly practiced surgical options for MU. Though free flaps are gaining popularity for various oncoplastic reconstruction, they are not frequently used for MU. A free anterolateral thigh (ALT) flap may have a beneficial role as it provides simultaneous coverage for a large defect after radical tumor and scar excision. Methods Between January 2015 and December 2018, 11 patients with lower limb MU reconstructed with free ALT flap were reviewed retrospectively for the surgical procedure, recurrences, and functional outcomes. Results Mean dimensions of the defect and flaps were 8 cm × 6 cm and 18.91 cm × 11 cm, respectively, and total flap coverage was obtained in nine cases. Marginal flap loss was noted in one and residual contracture in two cases. selleck kinase inhibitor Functional improvement of the limb was achieved in all cases. Recurrence or disease-related mortality was not seen in any patient after a mean follow-up of 35.82 months. Conclusions Free ALT flap reconstruction of MU of extremity facilitates most radical tumor and scar-contracture removal and thus reduces the chances of re-ulceration. It facilitates local radiotherapy protocol with the provision of immediate durable coverage. Thus, it has a beneficial role other than a secondary reconstructive procedure. Moreover, an added benefit may be obtained with a "flow-through' flap" to avoid amputation and improve functional outcomes.Background Patients with avascular necrosis related to sickle cell disease (SCD) can be severely disabled by the severe degenerative changes of their hip. Total hip arthroplasty (THA) remains the only surgical option for some of these patients. Total hip arthroplasty can be a challenging procedure, and SCD patients demonstrate high percentages of medical, intraoperative, and postoperative complications and implant failure. Furthermore, the need for THA following avascular necrosis in the Eastern Province of Saudi Arabia is high, and the subsequent risk of periprosthetic fracture is prevalent. Therefore, it is crucial to conduct such a study. Aim of the study This cross-sectional retrospective study aimed to assess the prevalence and associated risk factors for periprosthetic fractures during total hip arthroplasty in sickle cell disease patients at King Fahad Hospital Hofuf, Saudi Arabia. Methods We collected the data of all SCD patients who had undergone THA during the study period, January 2015 to September 2020.
