Moreover, among the participants, female gender, age, fewer years from HIV diagnosis and not being aware of their own viremia were associated to a higher risk of negative psychological outcomes. Almost half of our PLWH sample experienced significant levels of distress related to the COVID-19 pandemic. Women, elderly patients and those with recent HIV diagnosis appear to be the more psychologically fragile subgroups. Our findings could help identify patients most in need of psychological interventions to improve the wellbeing of PLWH.Direct viral damage and uncontrolled inflammation contribute to disease severity in SARS-CoV-2 infection. The aim of this study was to investigate the prognostic significance of neutrophil-to-lymphocyte [NLR], lymphocyte-to-monocyte [LMR] and platelet-to-lymphocyte [PLR] ratios in COVID-19 patients. All 184 COVID-19 patients hospitalized in our institution between March – April 2020 were retrospectively analyzed. The patients were grouped into intubated and non-intubated, and subgrouped into survived and deceased. An unpaired Student’s t-test was used for continuous variables, and the Pearson Chi-square (χ2) test for categorical. Univariate and multivariate logistic regression models were developed to assess the independent relationship between NLR, LMR and PLR and unfavorable outcomes. Non-parametric correlations were calculated using Spearman’s Rho correlation coefficient. The mean age of the patients was 64.7; mean BMI was 29.10; 73 (39.67%) were female and 111 male (60.33%). No statistical difference between groups was identified with regard to NLR (mean 8.29, standard deviation [SD] 7.86). On multivariate regression analysis, only PLR and LMR were shown to influence the ratio and it was positively correlated with PLR, lactate and C-reactive protein [CRP]. LMR for non-intubated survived [NI-S] (mean 2.29, SD 1.31) and non-intubated deceased [NI-D] (mean 1.79, SD 0.81) groups were statistically significant (p=0.03). LMR was influenced only by NLR on regression analysis. A positive correlation of LMR with body mass index [BMI] was ascertained. No statistical significance was found between groups for PLR (mean 269.85, SD 207.98) and the ratio was influenced by age and NLR on regression analysis, and positively correlated with NLR. To conclude, previously reported findings of a prognostic role of NLR, LMR and PLR in COVID-19 were not validated in our cohort and we would caution against using the ratios in question as independent markers for disease severity.The aim of this study was to determine the relationship between COVID-19 severity and androgenic alopecia in patients hospitalized in the Surgery Service of Honorio Delgado Espinoza Hospital in Arequipa, Peru. A cross-sectional study was performed in male patients with a diagnosis of COVID-19. Alopecia, clinical characteristics, treatment, and evolution were collected. In all, 98 patients were included; median age was 55 years old (range 18-89), 32.7% with comorbidities, and 45.9% with androgenic alopecia. The severity of COVID-19 infection was moderate to severe in 13.2% of patients without alopecia, and in 88.9% of patients with alopecia (p>0.001). In the logistic regression model analysis, patients with alopecia had a higher risk of presenting moderate to severe symptoms due to SARS-CoV-2 infection (OR 80.2; 95% CI 16.2-397.7). In conclusion, the severity of infection was statistically significant in patients over 60 years old and those with alopecia.Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), the causative pathogen for the COVID-19, first emerged in Wuhan, China, in December 2019 and by March 2020, it was declared a pandemic. COVID-19 pandemic has overburdened healthcare systems in most countries and has led to massive economic losses. SARS-CoV-2 transmission typically occurs by respiratory droplets. The average incubation period is 6.4 days and presenting symptoms typically include fever, cough, dyspnea, myalgia or fatigue. While the majority of patients tend to have a mild illness, a minority of patients develop severe hypoxia requiring hospitalization and mechanical ventilation. Management is mostly supportive. However, several direct anti-viral agents, and immunomodulatory therapy with steroids and various cytokine blockers seem promising in early results. However, an effective vaccine has been established, which will help curb the pandemic.Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic worldwide. On a daily basis the number of deaths associated with COVID-19 is rapidly increasing. The main transmission route of SARS-CoV-2 is through the air (airborne transmission). This review details the airborne transmission of SARS-CoV-2, the aerodynamics, and different modes of transmission (e.g. droplets, droplet nuclei, and aerosol particles). SARS-CoV-2 can be transmitted by an infected person during activities such as expiration, coughing, sneezing, and talking. During such activities and some medical procedures, aerosols and droplets contaminated with SARS-CoV-2 particles are formed. Depending on their sizes and the environmental conditions, such particles stay viable in the air for varying time periods and can cause infection in a susceptible host. Very few studies have been conducted to establish the mechanism or the aerodynamics of virus-loaded particles and droplets in causing infection. In this review we discuss the various forms in which SARS-CoV-2 virus particles can be transmitted in air and cause infections.In this review, we summarize the possible mechanisms of COVID-19-associated coagulopathy and compare its features to other similar conditions. The recent COVID-19 pandemic has caused enormous mortality and morbidity worldwide. It is important to note that COVID-19-associated thrombotic events play a huge role in the morbidity of this disease. Interestingly, it has been observed that this complication may occur despite prophylactic anticoagulant therapy. Recent studies on COVID-19-associated coagulopathy revealed that the COVID-19-associated hypercoagulability is more frequently observed among those with a severe course of the disease. Amcenestrant in vitro Various mechanisms have been suggested as explanations for this condition and possible underlying etiologies.
