05). While the probability PDDIs statistically significantly increased 3.73 times (OR (Odds Ratio) =3.73; 95% CI= 1.47-9.50) in patients who used a single antibiotic compared to patients who did not use antibiotics (p=0.006), the probability of the occurrence of PDDIs by using more than one antibiotic was statistically significantly 8.5 times (95% CI =3.30-21.89) (p <0.001).

Our study results showed that the use of antimicrobial drugs (antibiotic, antifungal, antiviral) was found to be statistically significantly higher (p<0.05) in the group with PDDIs.

Serum D-dimer levels, as well as other biomarkers related to coagulation, are significantly elevated during severe community acquired pneumonia. The aim of this study is to investigate the utility of plasma D-dimer levels determining the severity of inflammation and prognosis in pediatric patients with COVID-19 infection.

We retrospectively chart reviewed medical records of pediatric patients (< 18 years of age) admitted to Istanbul Fcaulty of Medicine, Department of Pediatrics Infectious Disease Service between March 11, and June 30, 2020. We collected demographic, clinical, biochemical and radiographic data.

A hundred and seventy-one pediatric patients (1 - 216 months of age) admitted to pediatric infecitous disease service included in this study. Patients were classified into 4 categories; 1) COVID-19 infection confirmed by PCR, 2) Suspected COVID-19 infection due to close exposure history and radiographic findings, 3) Lower respiratory tract infection other than COVID-19 confirmed with multiplex respiratory viral panel, and 4) Systemic infections other than lower respiratory tract infection. Lymphopenia was observed significantly higher in patients with COVID-19 infection compared to patients with other respiratory viral infections (p=0.06). In patients with radiographic findings concerning for COVID-19 infection, elevated serum D-dimer levels were detected significantly higher than lymphopenia (p=0.07).

Elevated serum D-dimer levels at baseline are associated with inflammation especially in patients with COVID-19 infection with radipgraphic findings. Monitoring serum D-dimer levels may be used for early identification of severe cases in children.

LM is very rare in young patients and, for this reason, it can be commonly misdiagnosed. We describe the case of a locally recurrent LM in a 19-year-old male patient, which initially arose at the age of 17 years. In order to avoid diagnostic pitfalls, clinicians have to put more emphasis on diseases which previously were prerogative only of elderly patients and that now could begin to engage a younger age, according to climate and behavior changes.The Santa Maria and San Gallicano Hospital represents one of the first dermatological centers founded in the world; since its establishment its aim is to treat widespread skin diseases such as leprosy, scabies, ringworm, prurigo and mange. Its construction began on March 14, 1725 with a ceremony held for the laying of the foundation stone. Its official inauguration, however, is dated October 6, 1726 when Pope Benedict XIII issued the Bonus ille Seal. The hospital's origins stem from the apostolic and charitable work by Father Emilio Lami, who was its first prior, and by the tenacious will of Cardinal Pietro Marcellino Corradini who was its protector. As can be seen by the marble plaque, still preserved and dated 1725, the health facility was intended for people with skin diseases. Venereal affections, such as syphilis and gonorrhea, were instead treated starting from the second half of the 19th century under the direction of Dr. Pietro Shilling and subsequently Dr. Gaetano Ciarrocchi. MMP inhibitor Since the 18th century, the hospital, built initially by architect Filippo Raguzzini, underwent expansion work including the construction of the "Nuova Corsia dei ragazzi tignoselli" ward, the "Anatomical Theater" of great artistic value and of the "Celtic Rooms." More recently, from the 1939, the hospital obtained, and still maintains today, the recognition as an Institute for Hospitalization and Care of a Scientific Nature (IRCCS); a clear indication of its authoritativeness and value during almost three centuries of history.
Although it is near concluded that renin-angiotensin system inhibitors do not have a harmful effect on coronavirus disease 2019 (COVID-19), there is no report about whether angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) offer any protective role. This study aimed to compare the association of ARBs and ACEIs with COVID-19-related mortality.

All patients with COVID-19 in Korea between January 19 and April 16, 2020 were enrolled. The association of ARBs and ACEIs with mortality within 60 days were evaluated. A comparison of hazard ratio (HR) was performed between COVID-19 patients and a retrospective cohort of pneumonia patients hospitalized in 2019 in Korea.

Among 10,448 COVID-19 patients, ARBs and ACEIs were prescribed in 1,231 (11.7%) and 57 (0.6%) patients, respectively. After adjusting for age, sex, and history of comorbidities, the ARB group showed neutral association (HR, 1.034; 95% CI, 0.765 to 1.399; p = 0.8270) and the ACEI groups showed no significant associations likely owing to the small population size (HR, 0.736; 95% CI, 0.314 to 1.726; p = 0.4810). When comparing HR between COVID-19 patients and a retrospective cohort of patients hospitalized with pneumonia in 2019, the trend of ACEIs showed similar benefits, whereas the protective effect of ARBs observed in the retrospective cohort was absent in COVID-19 patients. Meta-analyses showed significant positive correlation with survival of ACEIs, whereas a neutral association between ARBs and mortality.

Although ARBs or ACEIs were not associated with fatal outcomes, potential beneficial effects of ARBs observed in pneumonia were attenuated in COVID-19.

Although a rapid response system (RRS) can reduce the incidence of cardiopulmonary resuscitation (CPR) in general wards, avoidable CPR cases still occur. This study aimed to investigate the incidence and causes of avoidable CPR.

We retrospectively reviewed the medical records of all adult patients who received CPR between April 2013 and March 2016 (35 months) at a tertiary teaching hospital where a part-time RRS was introduced in October 2012. Four experts reviewed all of the CPR cases and determined whether each event was avoidable.

A total of 192 CPR cases were identified, and the incidence of CPR was 0.190 per 1,000 patient admissions. Of these, 56 (29.2%) were considered potentially avoidable, with the most common cause being doctor error (n=32, 57.1%), followed by delayed do-not-resuscitate (DNR) placement (n=12, 21.4%) and procedural complications (n=5, 8.9%). The percentage of avoidable CPR was significantly lower in the RRS operating time group than in the RRS non-operating time group (20.7% vs. 35.5%; P=0.026). Among 44 avoidable CPR events (excluding cases related to DNR issues), the rapid response team intervened in only three cases (6.8%), and most of the avoidable CPR cases (65.9%) occurred during the non-operating time.

A significant number of avoidable CPR events occurred with a well-functioning, part-time RRS in place. However, RRS operation does appear to lower the occurrence of avoidable CPR. Thus, it is necessary to extend RRS operation time and modify RRS activation criteria. Moreover, policy and cultural changes are needed prior to implementing a full-time RRS.

A protective outer layer was an effective strategy to solve this problem. However, the commonly used coating techniques are too complicated or too difficult to accurately control, thus, the applicability was relatively low. In this study, a water stable MOF core-SiO2 shell nanomaterial (Fe-MOF-74@SiO2) was synthesized by a facile hydrothermal method, and applied to activate persulfate (PS) for dimethyl phthalate (DMP) degradation. The catalyst water stability and DMP degradation in the system were investigated, suggesting that the SiO2-coated catalyst was more stable and exhibited higher DMP degradation efficiency over the pure MOF. It was found that pH had negligible effects on Fe-MOF-74@SiO2 + PS system, while, higher temperature facilitated the degradation of DMP. The activation mechanism was studied by quenching experiments combined with electron paramagnetic resonance, indicating that SO4⋅- played a major role in the activation of PS with Fe-MOF-74@SiO2 for DMP removal, while ⋅OH also involved in the catalytic process. Finally, possible DMP degradation pathways were proposed. These findings indicated that the core-shell structured Fe-MOF-74@SiO2 showed promise for DMP degradation by PS advanced oxidation system.Frequent oil-spill accidents not only cause serious and long-term damage to marine ecosystems, but also lead to a huge loss of valuable natural resources. To lighten the environmental pollution of oil spills as quickly as possible, an efficient and environment-friendly approach for oil-water separation is highly desirable. Herein, a facile one-pot room-temperature approach was developed for large-scale fabrication of covalent organic framework-coated superhydrophobic sponges (sponges@COFs). The as-prepared sponges@COFs possessed many superior properties, including superhydrophobicity with the water contact angle of approximately 154.3°, large specific surface area (153.059 m2/g), high porosity of the network structures, as well as good mechanical and chemical stability. Taking the aformentioned advantages together, the superhydrophobic sponges showed ultra-high adsorption capacity for oil and various organic solvents. In comparision with its own weight, the adsorption amount of the sponges@COFs for silicone oil was up to 150 times and for toluene was 125 times, respectively. Furthermore, the superhydrophobic sponges also showed fast and highly efficient oil-water separation, outstanding flame retardancy and recyclability. In addition, the sponges@COFs were successfully applied to the high-efficiency removal of oil suspension from industrial waste water, firmly confirming their application prospect in industrial wastewater treatment.
