Bibliometric Study of Scientific Productivity on the Impacts on Mental Health in Times of Pandemic.
Background and Objectives: The presence of the new SARS-CoV-2 virus is causing enormous threats to people's health and lives, so quantifying the scientific productivity on mental health in times of pandemic is an urgent need, especially to expand the degree of knowledge on mental health problems in regions of low scientific productivity. The aim was to characterize the bibliometric indicators of scientific productivity on mental health during the pandemic in the PubMed Identifier database of the National Library of Medicine in the United States. Materials and Methods: A documentary study (bibliometric) of the scientific productivity on mental health in times of pandemic from January 2020 to June 2021 was carried out. ⋯ A second group comprised Bangladesh, China, USA, and Spain, with 3 studies each; and a third group comprised 13 countries (Albania, Saudi Arabia, Argentina, Brazil, South Korea, Denmark, Ecuador, Egypt, Greece, Japan, Jordan, Kuwait, and New Zealand) with one study each. Conclusions: Bibliometric indicators of scientific productivity on mental health during the COVID-19 pandemic have ostensibly increased. We verified 47 studies in PubMed, which could serve to improve the understanding and management of COVID-19, as well as serve as a thought-provoking means for other countries and researchers to publish on the state of mental health during and post pandemic.

Background and Objectives: Symptoms and hemodynamic findings during orthostatic stress have been reported in both long-haul COVID-19 and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), but little work has directly compared patients from these two groups. To investigate the overlap in these clinical phenotypes, we compared orthostatic symptoms in daily life and during head-up tilt, heart rate and blood pressure responses to tilt, and reductions in cerebral blood flow in response to orthostatic stress in long-haul COVID-19 patients, ME/CFS controls, and healthy controls. Materials and Methods: We compared 10 consecutive long-haul COVID-19 cases with 20 age- and gender-matched ME/CFS controls with postural tachycardia syndrome (POTS) during head-up tilt, 20 age- and gender-matched ME/CFS controls with a normal heart rate and blood pressure response to head-up tilt, and 10 age- and gender-matched healthy controls. ⋯ Cerebral blood flow and cardiac index reductions during tilt were more severely impaired than in many patients with ME/CFS. The finding of early-onset orthostatic intolerance symptoms, and the high pre-illness physical activity level of the long-haul COVID-19 patients, makes it unlikely that POTS in this group is due to deconditioning. These data suggest that similar to SARS-CoV-1, SARS-CoV-2 infection acts as a trigger for the development of ME/CFS.

Background and objectives: The aim of the current study was to assess the use of determinations of total alcohol dehydrogenase and the activity of its isoenzymes as well as aldehyde dehydrogenase in the serum of patients with alcohol liver disease. Materials and Methods: The testing was performed on the serum of 38 patients with alcoholic fatty liver (26 males and 12 females aged 31-75). The total activity of ADH was determined by the colorimetric method. ⋯ Results: A statistically significantly higher ADH I activity was noted in the serum of patients with alcoholic fatty liver (4.45 mIU/L) compared to the control group (2.04 mIU/L). A statistically significant increase in the activity was also noted for the class II alcohol dehydrogenase isoenzyme (29.21 mIU/L, control group: 15.56 mIU/L) and the total ADH (1.41 IU/L, control group: 0.63 IU/L). Conclusions: The obtained results imply the diagnostic usefulness of the determination of AHD total, ADH I, and ADH II activity in the serum of patients with alcoholic fatty liver.

Chronic lymphocytic leukemia (CLL) treatment strategies have evolved to include mechanism-driven drugs but now raise new questions regarding their optimum timing and sequencing. In high-risk patients, switching from pathway inhibitors to allogeneic stem cell transplantation (allo-HCT) is still a matter of intense debate. ⋯ Early relapse after allo-HCT urged the initiation of salvage therapy, including donor lymphocytes infusions, ibrutinib, and venetoclax. We aim to outline and discuss the potential benefits of novel therapies, the current role of allo-HCT in CLL, drug timing and sequencing, and the unmet need to improve the long-term outcome of high-risk CLL patients.

Background and Objectives: Hypertrophic cardiomyopathy (HCM) depends on the primary impairment of sarcomeres, but it can also be associated with secondary alterations in the heart related to oxidative stress. The present study aimed to examine oxidative-antioxidant disturbances in patients with HCM compared with control individuals. Materials and Methods: We enrolled 52 consecutive HCM patients and 97 controls without HCM. ⋯ Lipid peroxidation markers also demonstrated good predictive power to detect HCM patients [AUCLPH = 0.73, AUCMDA = 0.79]. Conclusions: The TOS, the TAC, LPH levels, and MDA levels have good predictive power for HCM detection. The holistic assessment of oxidative stress by the OSI had excellent power and could identify patients with HCM.
