It is necessary to know the viral kinetics and conduct epidemiologic investigations of confirmers to prevent the spread of the new infectious disease COVID-19 to the community. To date, no study has been published on viral kinetics during the preclinical and clinical periods of SARS-CoV-2.

A confirmed case was defined as a patient with positive results by real-time reverse transcription polymerase chain reaction (RT-PCR) assay for SARS-CoV-2. Both specimen types were collected over the whole clinical course in all patients. Asymptomatic patients who had been screened for COVID-19 due to a strong epidemiologic link were also enrolled. The study population included 54 hospitalized patients with confirmed COVID-19.

COVID-19 shows a very high viral load on the day of symptom development which then decreases overall. Rapid viral proliferation was observed 0-5 days before symptoms developed. Cycle threshold (Ct) value was lowest in clinical course from 5 days before symptoms to 10 days after symptoms occurredations. Since there is very low possibility of transmission after 10 days of symptom occurrence, it may be considered to release isolation after 10 days of symptom occurrence in limited resource situations. This study allows for the planning of epidemiological investigations, patient's ward supply, and follow-up of patients through sequential changes in viral loads over the entire clinical course. In addition, it is possible to estimate the clinical time at which the patient is present.The management of intraductal papilloma (IDP) diagnosed on core needle biopsy (CNB) is controversial due to the variable upgrade rates to breast carcinoma (BC) on subsequent surgical excision reported in the literature. The purpose of our study was to investigate the upgrade rate of IDP diagnosed on CNB to BC in subsequent surgical excision and the impact of clinical, pathologic and radiologic variables. This is a retrospective cohort of all women who had a diagnosis of IDP on a CNB between 2005 and 2018 in a tertiary academic center with subsequent surgical excision. Upgrade was defined as ductal carcinoma in situ (DCIS) and invasive carcinoma on surgical excision. Statistical analyses included Pearson's chi-square, Wilcoxon rank-sum and logistic regression. A total of 216 women with IDP in a CNB were included. Arabinofuranosyl Cytidine Nineteen patients (8.8%) upgraded to BC in the overall cohort, including 14 DCIS and 5 invasive carcinomas. An upgrade rate of 27% was found in atypical IDP (14 of 51 cases), while only 3% of pure IDP upgraded to BC (5 of 165 cases). Older age (>53 years) at time of biopsy (OR=1.05, 95%CI 1.01-1.09, p=0.027) and concomitant atypical ductal hyperplasia (ADH) (OR=9.69, 95%CI 3.37-27.81, p less then 0.0001) were significantly associated with upgrade. Our results support surgical excision of IDP on CNB when associated with ADH or diagnosed in women older than 53 years of age. The low surgical upgrade rate of 3% for pure IDP on CNB in younger women should be part of the management discussion.We describe a case of a cholecystoduodenal fistula (CDF) diagnosed using oral contrast-enhanced ultrasound (CEUS). CDF is a rare type of biliary-enteric fistulation in which an abnormal communication forms between the gallbladder and duodenum. CDF are usually found in older patients, in the context of chronic cholecystitis, and can be associated with serious consequences. Given the non-specific presentation and limitations of the various imaging modalities, CDF are notoriously difficult to diagnose. CEUS is a recognised technique predominantly deployed for imaging following intravenous administration. Experience of CEUS has expanded into endocavitary use, including in the biliary and gastrointestinal systems. We describe a case of a CDF identified on intracavitary CEUS. This case report demonstrates oral ingestion of a diluted ultrasound contrast agent is a novel and safe mode of administration with stability of the contrast agent and the ability to define fistulation.

The aim of this study was to group the patients with total knee arthroplasty(TKA) surgery according to the World Health Organization (WHO) obesity classification and to evaluate the effects of body mass index (BMI) on complication rates, the functional and clinical outcomes of the patients after TKA.

Between 2011 and 2018, 588 patients who underwent TKA by a single surgeon were retrospectively evaluated. According to WHO's classification criteria, 588 patients were divided into 5 groups such as normal (< 25.0kg/m

, n 138, 23.4%), overweight (25.0-29.9kg/m

n 201, 34.1%), class I obese (30.0-34.9kg/m

n 124, 21%), class II obese (35-39.9kg/m

n 82, 13.9%) and class III obese (> 40kg/m

n 43 7.6%). Groups were compared in terms of age, sex, surgical side, follow-up period, case duration, prosthesis infection and aseptic prosthesis loosening rates, Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm functional scores and knee flexion degrees.

There was a statistically significant difference between the groups in terms of prosthesis infection or aseptic prosthesis loosening following TKA. The incidence of these complications increased as BMI increased (X2 20,079, p 0.01). Postoperative knee flexion degrees, KOOS and Lysholm scores were significantly different between the groups (p 0.000). As BMI increased, clinical and functional outcomes deteriorated.

Obesity is one of the most important risk factors for prosthesis infection and aseptic prosthesis loosening which can be seen after TKA. High BMI values also adversely affect clinical and functional outcomes after TKA.

We hypothesised that immune deregulation associated with MPNs may affect the immune response gained following vaccinations when compared to healthy controls. Using deep immunophenotyping with high-dimensional single-cell analysis and mass cytometry we could demonstrate an altered immune response in MPN patients following vaccination. We found that prior to vaccination, MPN patients had reduced numbers of naive CD4 T cells. Furthermore, at 3-weeks and 3-months post-vaccination there was evidence of both delayed and impaired B- and T-memory cells responses. Thus, although, the immune systems of MPN patients can 'recognise' the Influenza A vaccine, the response appears inferior compared to healthy controls.
