In January 2020, the COVID-19 pandemic started and has severely affected all countries around the world. The clinical symptoms alone are not sufficient for a proper diagnosis. Thus, molecular tests are required. Various institutes and researchers developed real-time PCR-based methods for the detection of the virus. However, the method needs expensive equipment. In the present study, we developed a real-time NASBA assay for the detection of SARS-CoV-2. ⋯ The results of the present study show that the developed real-time NASBA is a sensitive and specific method for the detection of SARS-CoV-2 and is comparable with real-time PCR. NASBA is an isothermal signal amplification method, and if stand-alone fluorescent readers are available, the real-time NASBA can be used without the need for expensive thermocyclers. In addition compared to other isothermal methods like LAMP, the primer design is straightforward. Thus, real-time NASBA could be a suitable method for inexpensive SARS-CoV-2 detection.

The pandemic caused by the SARS-CoV-2 virus has triggered great interest in the search for the pathophysiological mechanisms of COVID-19 and its associated hyperinflammatory state. The presence of prognostic factors such as diabetes, cardiovascular disease, hypertension, obesity, and age influence the expression of the disease's clinical severity. Other elements, such as 25-hydroxyvitamin D (25(OH)D3) concentrations, are currently being studied. ⋯ Thus, there are biological factors linking vitamin D to the cytokine storm, which can herald some of the most severe consequences of COVID-19, such as acute respiratory distress syndrome. Hypovitaminosis D is widespread worldwide, so the prevention of COVID-19 through vitamin D supplementation is being considered as a possible therapeutic strategy easy to implement. However, more-quality studies and well-designed randomized clinical trials are needed to address this relevant question.

Chronic pain can trigger both physical and mental health complications. During the COVID-19 pandemic, patients with chronic diseases have had reduced access to some medications. ⋯ The pharmacological management of patients with chronic pain is heterogeneous, and this real-world study showed that a high proportion of patients experienced an interruption of pain management during the 12 months following the onset of the COVID-19 pandemic.

The newly described SARS-CoV-2 respiratory virus is now righteously presenting as an ominous threat, based on the speed with which it originated a zoonosis from bats; advancing at a similar rate, the virus has placed mankind before a pandemic, with an infection toll of some 431 million, and a lethality of 5,9 million (as of February 25, 2022). The size of the harm that this agent can unleash against us is appallingly wide, from brain ischemia to foot chilblain, passing by heart massive infarction. ⋯ This will have to be avoided, and surveillance of society on psychological terms will be one tenet. Needless to say, the role of the enteric tract in these issues is growing higher, and it will be narrated to seal the matters with the last (not the least) touch of glue.

Does the COVID-19 personal protective equipment impair the surgeon's performance?
Despite increasing vaccination rates, new viral variants of SARS-CoV-2 (severe acute respiratory syndrome coronavirus type 2) are advancing the COVID 19 (coronavirus disease 2019) pandemic and continue to challenge the entire world. Surgical care of SARS-CoV-2 positive patients requires special protective measures. We hypothesized that "COVID-19" personal protective equipment (PPE) during surgery of SARS-CoV-2 positive or potentially positive patients would negatively affect the surgeon and thus the surgical outcome. ⋯ Level I.
