Molecular and Source-Specific Profiling of Hospital Staphylococcus aureus Reveal Dominance of Skin Infection and Age-Specific Selections in Pediatrics and Geriatrics.

Staphylococcus aureus is a major human-associated pathogen that causes a wide range of clinical infections. However, the increased human dynamics and the changing epidemiology of the species have made it imperative to understand the population structure of local ecotypes, their transmission dynamics, and the emergence of new strains. Since the previous methicillin-resistant S. aureus (MRSA) pandemic, there has been a steady increase in global healthcare-associated infections involving cutaneous and soft tissue and resulting in high morbidities and mortalities. Limited data and paucity of high-quality evidence exist for many key clinical questions about the pattern of S. aureus infections. Using clinical, molecular, and epidemiological characterizations of isolates, hospital data on age and infection sites, as well as antibiograms, we have investigated profiles of circulating S. aureus types and infection patterns. We showed that age-specific profiling in both intensive care unit (ICU) and non-ICU revealed highest infection rates (94.7%) in senior-patients > 50 years; most of which were MRSA (81.99%). However, specific distributions of geriatric MRSA and MSSA rates were 46.5% and 4.6% in ICU and 35.48% and 8.065% in non-ICU, respectively. Intriguingly, the age groups 0−20 years showed uniquely similar MRSA patterns in ICU and non-ICU patients (13.9% and 9.7%, respectively) and MSSA in ICU (11.6%). The similar frequencies of both lineages in youth at both settings is consistent with their increased socializations and gathering strongly implying carriage and potential evolutionary replacement of MSSA by MRSA. However, in age groups 20−50 years, MRSA was two-fold higher in non-ICU (35%) than ICU (18.6%). Interestingly, a highly significant association was found between infection-site and age-groups (p-value 0.000). Skin infections remained higher in all ages; pediatrics 32.14%, adults 56%, and seniors 25% while respiratory infections were lower in pediatrics (14.3%) and adults (17%) while it was highest in seniors (38%). Blood and "other" sites in pediatrics were recorded (28.6%; 25%, respectively), and were slightly lower in adults (18.6%; 8.6%) and seniors (14%; 22.8%), respectively. Furthermore, a significant association existed between infection-site and MRSA (Chi-Square Test, p-value 0.002). Thus, the common cutaneous infections across all age-groups imply that skin is a significant reservoir for endogenous infections; particularly, for geriatrics MRSA. These findings have important clinical implications and in understanding S. aureus profiles and transmission dynamics across different age groups that is necessary for strategic planning in patient management and infection control.

Venous thromboembolism in COVID-19: A meta-summary of cases.

OBJECTIVES: To summarize cases of venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT) among coronavirus disease (COVID-19) patients and discuss their symptoms, diagnostic method, clinical features, and prognosis. METHODS: All major databases were searched for relevant studies published between December 1, 2019 and May 5, 2021. RESULTS: A total of 233 articles were identified, 22 describing 48 patients were included. A total of 79.1% had PE and 20.9% had DVT. Most patients were men, with a mean age of 56 years. Comorbidities were present in 70.8%, and 85.4% had at least one risk factor of VTE. 56.3% had received anticoagulation therapy. Most patients were treated in the general ward. Complications occurred in 27.1% of the patients, and recovery was achieved in 80.4%. CONCLUSION: Venous thromboembolism must be suspected even in patients who had received prior anticoagulant regimens or in stable cases, especially in males, the elderly, and patients with comorbidities and high D-dimer levels.

Depression among physicians and other medical employees involved in the COVID-19 outbreak: A cross-sectional study.

ABSTRACT: Health care employees are the front liners whom are directly involved in the management of COVID-19 at high risk of developing psychological distress and other mental health illness. We aim to assess the burden of depression during this pandemic on health care employees treating COVID-19 in Saudi Arabia. We also will shed the light on the best solutions of how to encounter depression.A cross-sectional, hospital-based survey conducted via a region-stratified, 2-stage cluster sample was conducted for 554 participants in >15 hospitals from April 29, 2020, to June 30, 2020. Depression is measured using the established PHQ9 score system. We grade PHQ9 depression scores as: normal, 0 to 4, mild, 5 to 9, significant (moderate or severe), 10 to 27. χ2/Fisher exact test was used; significant association between level of depression and survey characteristics were made. P value <0.05 was considered statistically significant.A total of 554 participants completed the survey. A total of 18.9% (n = 105) were aged <29 years, 51.2% (n = 284) were between 30 to 39 years and female represent 70% of all participants. Of all participants, 53.7% (n = 298) were nurses, and 38.6% (n = 214) were physicians; 68.5% (n = 380) worked in central area hospitals in Saudi Arabia. No significant (P = .432, 95% confidence interval [CI]) association was observed between sex and depression classifications. However, female had high proportion of significant depression 75.0% (n = 76) was observed as compared to male 24.8% (n = 25). Depression was significant in Saudis 61.4% (n = 62) (P < .001, 95% CI) and medical staff who encountered corona patients 51.5% (n = 52) (P < .002, 95% CI). Hospital preparedness associated with more freedom of depression symptoms 69.1% (n = 199/288) (P < .001, 95% CI).Frontline young health care workers especially physician in Saudi Arabia reported a high rate of depression symptoms. Countermeasures for health care workers represent a key component for the mental and physical well-being as part of public health measures during this pandemic. Attention to hospital preparedness and adequacy of personal protective equipment contributed to milder depression symptoms. Further studies need to be conducted on crisis management and depression.
