Type 2 diabetes is associated with increased risk of critical respiratory illness in patients COVID-19 in a community hospital.

BACKGROUND: Type 2 diabetes (T2D) is the leading non-communicable disease worldwide and is associated with several microvascular and macrovascular complications. Individuals with T2D are more prone to acquiring selected types of infections and are more susceptible to complications due to these infections. This study aimed to evaluate the relationship between T2D and COVID-19 in the community setting. METHODS: This was a single-center retrospective analysis that included 147 adult patients with laboratory-confirmed COVID-19 admitted to a community hospital. Demographics, medical history, symptoms and signs, laboratory findings, complications during the hospital course, and treatments were collected and analyzed. The Kaplan-Meier method was used to describe the probability of intubation in patients with T2D as compared with patients without T2D. The hazard ratio for intubation in the survival analysis was estimated using a bivariable Cox proportional-hazards model. RESULTS: Of 147 patients, 73 (49.7%) had a history of T2D. Patients with T2D had higher requirement of ICU admission (31.5% vs 12.2%; p = .004), higher incidence of ARDS (35.6% vs 16.2%, p = .007), higher rates of intubation (32.9% vs 12.2%, p = .003), and higher use neuromuscular blocking agents (23.3% vs 9.5%, p = .02). In the survival analysis at 28 days of follow-up, patients with T2D showed an increased hazard for intubation (HR 3.00; 95% CI, 1.39 to 6.46). CONCLUSION: In our patient population, patients with COVID-19 and T2D showed significantly higher ARDS incidence and intubation rates. The survival analysis also showed that after 28 days of follow-up, patients with T2D presented an increased risk for shorter time to intubation.

Community hospital stethoscope cleaning practices and contamination rates.

BACKGROUND: In the United States, nosocomial infections are estimated to cause 72,000 annual deaths. The stethoscope, commonly used, is rarely reported as a potential vector. Our study aims to describe stethoscope contamination and the effect of self-reported cleaning practices among health care providers in a community hospital setting. METHODS: Stethoscopes were collected at random times from health care providers and cultured per standard techniques. Providers answered a structured questionnaire related to their cleaning practices. Differences in bacterial growth rates and the impact of profession, cleaning frequency, and prior sanitization were evaluated. RESULTS: Of 104 cultured stethoscopes, 44% were from residents and medical students, from which 76% had bacterial growth, and 56% were from attendings, nurses, and respiratory therapists who had 91.4% growth (95% = confidence interval 0.62-0.86 and 0.81-0.96, respectively). Overall, 86.5% of providers claimed disinfection frequency compliant with Center for Disease Control and Prevention guidelines but there were no statistical differences between self-reported cleaning frequency or methods, and the presence of bacteria. CONCLUSIONS: Most stethoscopes are contaminated with bacteria, the presence of which was not affected by reported cleaning strategies.

Ginsenoside Rk1 bioactivity: a systematic review.

Ginsenoside Rk1 (G-Rk1) is a unique component created by processing the ginseng plant (mainly Sung Ginseng (SG)) at high temperatures. The aim of our study was to systematically review the pharmacological effects of G-Rk1. We utilized and manually searched eight databases to select in vivo and in vitro original studies that provided information about biological, pharmaceutical effects of G-Rk1 and were published up to July 2017 with no restriction on language or study design. Out of the 156 papers identified, we retrieved 28 eligible papers in the first skimming phase of research. Several articles largely described the G-Rk1 anti-cancer activity investigating "cell viability", "cell proliferation inhibition", "apoptotic activity", and "effects of G-Rk1 on G1 phase and autophagy in tumor cells" either alone or in combination with G-Rg5. Others proved that it has antiplatelet aggregation activities, anti-inflammatory effects, anti-insulin resistance, nephroprotective effect, antimicrobial effect, cognitive function enhancement, lipid accumulation reduction and prevents osteoporosis. In conclusion, G-Rk1 has a significant anti-tumor effect on liver cancer, melanoma, lung cancer, cervical cancer, colon cancer, pancreatic cancer, gastric cancer, and breast adenocarcinoma against in vitro cell lines. In vivo experiments are further warranted to confirm these effects.

Definition of "persistent vomiting" in current medical literature: A systematic review.

BACKGROUND AND AIM: Persistent vomiting is mentioned as a symptom of a large variety of systemic disorders. It is commonly used interchangeably with chronic, recurrent, or intractable vomiting and widely used as a warning sign of severe illness in dengue infection. However, it has been poorly defined in the medical literature. Therefore, we aimed to systematically review a definition of persistent vomiting in the medical literature. METHODS: A systematic search was done through; PubMed, Google Scholar, Web of Science, Scopus, VHL, WHO-GHL, Grey Literature Report, POPLINE, and SIGLE for the last 10 years. Consensus on the definition was considered to be reached if at least 50% of studies described the same definition using the Delphi consensus technique. RESULT: Of 2362 abstracts reviewed, 15 studies were selected based on the inclusion criteria. Three studies used the same definition. Another 2 studies defined it as vomiting of all foods and fluid in 24 hours. Three studies defined persistent vomiting in the units of days or weeks. Four studies used the number of episodes: ≥2 episodes 15 minutes apart, >3 episodes in 12 hours, and >3 episodes within 24 hours. CONCLUSION: No consensus for the definition was found among authors. This is a point of concern that needs to be addressed by further studies.
